Surgery - Splenic Rupture
Introduction
Splenic rupture carrying a significant risk of intra-abdominal bleeding.
The American Association for the Surgery of Trauma's severity rating
Grade 1: Haematoma (less than 10% of surface area) or minor subcapsular tear (less than 1 cm)
Grade 2: Subcapsular hemorrhage that is not growing 10–50% of the surface area, with an intraparenchymal hemorrhage less than 5 cm in diameter
Grade 3: Ruptured subcapsular or intraparenchymal hemorrhage, laceration >3 cm or involving trabecular arteries, and subcapsular hemorrhage greater than 50% of surface area
Grade 4: Significant devascularization and laceration involving segmental or hilar vessels
Grade 5: Devascularized spleen with hilar vascular damage and shattered spleen
Etiology
Most often as a result of injuries from fast deceleration or non-penetrating trauma. connected to additional traumatic internal organ damage, such as rib fractures, and injuries to the pancreas, liver, kidney, and diaphragm. Splenomegaly and associated conditions such leukemia, infectious mononucleosis, and malaria "the risk of rupture from even small trauma."
Epidemiology
quite prevalent; up to 25% of instances involving major trauma have some degree of it.
History
Past experiences with blunt trauma. Abdominal pain that may be referred to the left shoulder tip (Kehr's sign) and may be localized or diffuse to the left flank.
Examination
discomfort, guarding, and stiffness in the abdomen (generalized or limited to the left flank).
symptoms of shock, such as tachycardia and hypotension.
Due to the creation of a subcapsular hemorrhage that eventually ruptures due to its expansion in size, there may be a delay in rupture for several days after the trauma.
Investigations
Blood: clotting, crossmatch, FBC, U&Es, and LFTs.
Ultrasound: Targeted sonography evaluation for trauma to identify any fluid in the peritoneal cavity that can indicate an intra-abdominal hemorrhage.
CT scan: To detect damage to other organs and the spleen.
CXR: May reveal a left pulmonary contusion, diaphragmatic rupture, or rib fractures.
Due to the availability of FAST and CT scanning, diagnostic peritoneal lavage—which detects free intraperitoneal blood—is rarely carried out.
Management
based on the degree of injury and the heamodynamic condition.
Wide-bore IV access, fluids, transfusion if required, and avoiding overinfusion (permissive hypotension may be tolerated) are the components of resuscitation. First grade and up to Grade 2: Exercise cautious management, closely observe, and reassess frequently. Take into account using interventional radiology procedures to sever a bleeding site. Grade 3: Laparotomy and perhaps a splenectomy or splenorrhaphy. Grades 4 and 5: partial excision.
Immunization against meningococcal (Men C), pneumococcal, and hemophilus organisms should be administered following surgery. Up until the age of 15, patients receive antibiotic prophylaxis as well, and they are advised to keep an antibiotic supply at home in case of infection.
Complications
From injury: bleeding, demise.
bleeding, sepsis following splenectomy, "risk of encapsulated organism infections, thrombotic vascular event (splenic/splanchnic venous thrombosis), pancreatitis, subphrenic abscess, gastric distension, and focal gastric necrosis" are among the consequences of splenectomy.
Rebleeding or thrombosis of the residual spleen from splenorrhaphy.
Prognosis
75% fatality rate in the absence of treatment. The range of mean mortality with therapy is 3% to 23%.

Branchial Cyst, Sinus and Fistula
Introduction
swelling or discharge in the neck resulting from pharyngeal pouches and clefts not fully obliterated during embryonic development.
Etiology
Ninety-five percent originate from congenital remnants of the branchial cleft or second pharyngeal pouch, while it's unclear exactly where they originated embryologically (perhaps ectopic tissue or incomplete involution).
Epidemiology
Not common. The most prevalent are branchial cysts, which typically manifest in the third decade and can vary greatly. In children, fistulae and sinuses are typically present.
History
The patient reports having a lateral neck swelling that fluctuates in size over time. Until inflammation and infection occur, the swelling is normally painless but eventually turns red and unpleasant. Mucus or mucopurulent fluid may leak from a neck dimple that is indicative of a sinus or fistula.
Examination
A lump is located at the intersection of the sternocleidomastoid's top and lower two-thirds, if this is indeed a cyst.
Upon palpation, the swelling is often oval-shaped, hard, and smooth. It can also fluctuate and transilluminate, as well as be somewhat soft in the early stages. There are 2% bilateral cases.
The intersection of the middle and lower thirds of the anterior margin of the sternocleidomastoid represents the external opening of a branchial sinus or fistula.
Pathogenesis
During the fifth week of fetal development, branchial clefts—neck grooves with branchial arches between—appear. The external auditory meatus, the first cleft, remains, while the other clefts usually vanish. Should the second cleft's remnants persist, a cyst, sinus, or fistula might form. Squamous or respiratory epithelium lines the cysts, which are filled with turbid fluid made up of cholesterol crystals and epithelial detritus, with lymphoid tissue present in some cases.
Between the internal and external carotid arteries, a branchial fistula terminates in the posterior portion of the tonsillar fossa in the oropharynx, superior to the hypoglossal nerve and inferior to the glossopharyngeal nerve.
Investigations
Imaging: To see the cyst, employ CT, MRI, or ultrasound scanning.
FNA: Used to differentiate cervical lymph node metastases in elderly patients from other types of cancer (such as thyroid cancer and mucoepidermoid carcinomas of the salivary glands, which may contain a significant cystic component).
Management
Surgery: The cyst and any related sinuses or tracts are surgically removed as part of the treatment. Usually, a transverse neck incision is used for this. To gain access to the cyst, the sternomastoid is retracted posteriorly and the platysma is separated. Subsequently, it is extracted with meticulous dissection, identification, and caution to prevent harm to any nerves, particularly the vagus, hypoglossal, and spinal accessory nerves. Before the cyst is removed, a branchial cyst abscess needs to be drained and antibiotics administered to prevent infection.
Complications
Incomplete excision of a sinus or fistula tract, infection, branchial cyst abscess, nerve injury during surgery.
Prognosis
Good, with full excision leading to a cure. Rates of recurrence are higher in cases of prior infection.

Surgery- Parathyroid Disease
Introduction
Primary hyperparathyroidism with hypercalcaemia and osteomalacia can be caused by benign parathyroid gland tumors (parathyroid adenomas) or parathyroid hyperplasia with excessive parathyroid hormone (PTH) release.
Malignancy (parathyroid adenocarcinomas) occurs seldom.
Etiology
It is uncertain exactly what causes these benign tumors to form. Past radiation exposure to the head, neck, and chest is linked to a higher risk of parathyroid adenomas.
One possible association between parathyroid adenomas and endocrine tumor syndromes is MENI and MENIIa.
Epidemiology
Seldom Used. One in a thousand, usually in the 50–70 age range.
History
frequently asymptomatic and detected by regular blood tests as hypercalcemia.
Hypercalcaemia symptoms could include:. weariness, arthralgia, and myalgia. bone ache. Nephrolithiasis. depression, anxiety, and diminished awareness. Pancreatitis
Other than the effects of hypercalcemia, an examination typically yields nothing.
Examination
Blood: bone profile (Ca2+, PTH), U&E (to evaluate fluid balance and electrolytes), plasma PTH.
Raised calcium levels in the urine.
Osteopenia and osteoporosis on plain radiographs. lesions in cystic bones.
To rule out sarcoidosis, use CXR.
Nuclear imaging: The location of the adenoma may be determined by technetium-99 scintigraphy.
US neck: Parathyroid adenomas may present differently.
To determine the severity of osteopenia or osteoporosis, a DEXA bone scan is required.
Management
IV rehydration with normal saline is the treatment for hypercalcemia. After rehydrating, keep up the fluid intake while using loop diuretics, such as furosemide, to improve renal calcium excretion.
Keep an eye on the other electrolytes. Take into account IV calcitonin, pamidronate (which increases bone resorption), or steroids (which are only useful in treating other causes of hypercalcaemia).
Surgery: Total parathyroidectomy (removal of all aberrant glands) and neck exploration.
Directed parathyroidectomy may be an option if the adenoma's location is well determined (requiring the use of more than one modality); alternatively, parathyroidectomy may be carried out under the guidance of intraoperative PTH level monitoring, since PTH levels begin to decline shortly after the adenoma is removed.
Complications
Surgical risks include the possibility of post-operative hypoparathyroidism from "hungry bone syndrome," which may necessitate temporary vitamin D and calcium supplements.
There is a significant danger of recurrent laryngeal nerve damage, particularly with thorough neck examination. Vocal cord paralysis can be detected by laryngoscopy, and some of the damage can be repaired partially by operating quickly to repair a severed nerve.
A large haematoma in the neck may need to be surgically removed in order to release the compressed trachea, which could compromise the airway.
consequences of hypercalcemia, such as osteoporosis, cognitive decline, and nephrolithiasis.
Good prognosis if the adenoma is completely removed. Many patients don't require any extra supplements.

Surgery - Salivary Gland Tumours
Introduction
tumors with a variety of histological subgroups that originate in either the major (parotid, submandibular, sublingual) or small salivary glands. 15% arise in the submandibular glands (30–50% malignant); 20% arise in the parotid glands (20% malignant); and 15% arise in the small salivary glands (>60% malignant). Less than 0.3 percent of sublingual gland tumors are malignant.
Etiology
Unknown Causes
Risk Factors
The following environmental factors have been identified: Epstein-Barr virus with lymphoepithelial tumors; smoking (Warthin's); radiation (Warthin's and mucoepidermoid carcinomama).
Epidemiology
comparatively uncommon; most affect adults. Pleomorphic adenoma has an average age of 42 years, Warthin's tumor has an average age of 60 years (male > female), acinic cell carcinoma affects women in their 50s, and squamous carcinomas attack men in their 70s.
History
A swelling that normally grows slowly and without pain. A malignant tumor increases the likelihood of pain.
Examination
Examining the edema and looking for indications of fixation is important. induration or ulceration of the mucosa or skin underlying it in locally advanced instances. One should use both hands to palpate the submandibular gland. examination of the mouth cavity because parapharyngeal space might become inflamed by deep lobe parotid tumors. facial nerve function in parotid lesions and signs of regional lymphadenopathy; weakness in this area should increase the possibility of malignancy.
Investigations
Imaging: To define the mass and its position in relation to adjacent structures and staging, ultrasound, CT, or MRI scans are utilized.
Tissue biopsy: FNA is a useful tool, however it is not a 100% reliable method for histological diagnosis.
Because of the possibility of tumor spilling, incisional or excisional biopsy of tumors in large glands should be avoided.
Histopathology:
& benign tumors About 80–85% of parotid gland tumors are pleomorphic adenomas. lack of a real capsule in epithelium or myoepithelial cells, which explains their propensity to regrow following excision.
Once called as adenolymphoma, Warthin's tumor (papillary cystadenoma lymphomatosum) accounts for 15% of parotid neoplasms and 10% of bilateral or multicentric tumors with glandular, cystic, and eosinophilic epithelium.
& Malignant carcinomas: Parotid cancer is the most common type of acinic cell carcinoma. broad histological spectrum accompanied with lymphocyte infiltrations.
The most prevalent malignant tumor of the parotid gland, mucoepidermoid carcinoma can range in malignancy from low grade to severe.
& Adenoid cystic carcinoma: aggressive with a perineural spread into the brain and the potential for late metastases; it is the sixth most common malignant carcinoma of the submandibular region.
& Aggressive forms of adenocarcinoma, squamous, and undifferentiated carcinomas.
& Non-epithelial tumors (such as lymphomas and haemangiomas): Very uncommon.
Management
Medical: Saved for infectious tumors or lymphomas.
Surgical: Both benign and malignant tumors can be removed.
Superficial or whole parotidectomy, with careful preservation of the facial nerve and its branches that pass between the deep and superficial lobes, is the treatment for parotid-related benign or low-grade cancers. Should the nerve be affected, it is possible to undertake sacrifice and prompt reconstruction using a nerve graft.
Submandibular: An incision in the submandibular triangle is used to address tumors.
Resection may be required if malignant tumors involve the lingual or hypoglossal nerves. This causes a partial loss of sensation and tongue movement; the patient should be informed of this. Additionally, there's a chance of harming the facial nerve's mandibular branch, which could cause asymmetry in the mouth and lower lip. If there is involvement of lymph nodes, neck dissection is done.
Palate cancers: Usually require a large excision and intricate repair.
Therapy: If the tumor is malignant, adjuvant post-operative radiotherapy ought to be administered.
Chemotherapy: Usually used for palliation, although not very effective.
Complications
Following a parotidectomy, there may be facial nerve damage, bleeding, necrosis of the skin flap, salivary fistula, and Frey's syndrome (10–50%), which is characterized by abnormal regeneration of postganglionic parasympathetic nerve fibers that typically innervate the parotid to sympathetic nerves of the sweat glands, causing gustatory sweating. Pleomorphic adenomas, because they feature pseudopod-like extensions extending from the tumor, are prone to recurrence even with simple enucleation.
Prognosis
If left untreated, pleuromorphic adenomas gradually increase and carry a 5% risk of developing into malignant transformation. Five-year survival for mucoepidermoid carcinoma is 70%; higher-grade types have a worse survival rate. Because perineural invasion is difficult to eliminate and has a tendency for late recurrence, adenoid cystic carcinoma has a poor prognosis. Only 25–50% of high grade tumors have a 10-year survival rate, compared to 80–95% for low grade tumors.

Surgery - Ingrowing Toenail
Introduction
An infection and inflammation are brought on by the lateral edge of a toenail growing into the soft tissue of the nail fold. Officially, it's called onychocryptosis.
Etiology
Along its edge, the toenail penetrates and develops into the skin. It may cause a bacterial or fungal infection on top of a foreign body reaction. Exuberant granulation tissue production can be the outcome of tissue healing.
Risk Factors
inadequately sized toenails, toe damage, ill cleanliness, and ill-fitting shoes—particularly those with tapering fronts.
Epidemiology
Typical. more typical in teenagers and young adults.
H HISTORY
Pain in the swollen toe and around the edges of the toenail. Ask about diabetes.
Examination
Warmth, discomfort, erythema, and oedema, usually on the big toe. Compared to the medial side of the toenail, the lateral side is more prone to be impacted.
Investigational studies
Usually not required.
Pus swab: Respect and tact if afflicted.
Toe radiograph: For osteomyelitis in diabetics and cases of severe infection.
Management
Medical: Podiatry care and basic analgesia for pain. If the foot appears early, it should be washed and dried carefully on a regular basis. Tips for keeping toenails trimmed transversely, as well as instructions on donning fresh socks and roomy shoes. If infected, antibiotics could be required (after incision and drainage if pus is present), particularly in diabetics.
Surgery: In cases that are severe or recurring. Local anesthesia with a ring-block.
If there is a localized pus collection, make an incision and drain the pus.
Avulsion of the nail: The toenail is cut off without damaging the nail bed. The likelihood of recurrence is about 50%.
Wedgeresection: Using phenol to kill the nail bed, the lateral portion of the nail that is ingrowing alongside the nail bed (about 25% of the nail) is excised. By doing this, the pressure on the toe's sides is released and the nail's regeneration into the skin is stopped.
Under Zadik's technique, the entire nail is extracted, and the nail bed is destroyed.
Complications
Permanent nail loss, malformation of the nail bed and surrounding toe, secondary infection of the nail and toe (typically fungal).
Prognosis
generally favorable if caught early. Up to 30% of cases recur. Diabetes has a greater morbidity rate and can result in toe (or perhaps limb) loss.

Surgery - Intestinal Ischemia
Introduction
Bowel necrosis and ischemia caused by obstruction (e.g., by an embolus or thrombosis) of a mesenteric artery.
Etiology
60% in emboli, 25% in arterial thrombosis, and 15% in venous thrombosis. may result from bowel strangulation inside a hernia, volvulus, intussusception, or surgical resection.
Risk Factors
Endocarditis for emboli, atrial fibrillation, and cardiac mural thrombus. For arterial thrombosis, hypertension, diabetes mellitus, and smoking are risk factors. Venous thrombosis is linked to splenectomy, portal hypertension, septic thrombophlebitis, and heart failure.
Epidemiology
Depending on the cause. more typical among older people.
H HISTORY
severe, intense stomach pain from colickiness. possibly accompanied by rectal bleeding or vomiting.
Past medical history of persistent mesenteric artery insufficiency, including significant weight loss and pain in the abdomen after eating. past liver or heart illness.
History and Examination
diffuse soreness and distension in the abdomen. a sensitive, palpable mass if a hernia is present. There could be no bowel sounds. unequal level of cardiovascular breakdown.
Investigations
Making the diagnosis might be challenging and may depend on a laparotomy or clinical suspicion.
Blood: FBC, U&Es, LFT, clotting, crossmatch, ABG (lactic acidosis).
AXR: May reveal thumbprinting or thickening of the intestinal wall.
CT scan: The intestinal wall may contain gas.
Mesenteric arteriography: Provides localization, assessment of the degree, and trial of intervention if stable.
Management
General: IV fluid resuscitation and electrolyte imbalance correction, IV antibiotics, nil by mouth.
Surgical: Infarcted bowel resection and emergency laparotomy. An embolectomy or a saphenous vein bypass from the iliac artery to the superior mesenteric artery below the blockage can be used to restore the vascular supply to the non-necrotic colon. A transient, non-functional stoma is frequently utilized. After surgery, close observation and care are necessary, usually on an ITU or HDU. Rarely, complete parenteral nourishment has been used to support large-scale small-bowel resection, which was then followed by small-bowel transplantation.
Medical: Heparin post-operative thrombosis prevention. Warfarinization over the long term could be advised.
Complications
multi-organ failure, intestinal perforation, peritonitis, and lactic acidosis.
Prognosis
It's a grave illness with a 50–100% fatality rate.
Introduction
Bowel necrosis and ischemia caused by obstruction (e.g., by an embolus or thrombosis) of a mesenteric artery.
Etiology
60% in emboli, 25% in arterial thrombosis, and 15% in venous thrombosis. may result from bowel strangulation inside a hernia, volvulus, intussusception, or surgical resection.
Risk Factors
Endocarditis for emboli, atrial fibrillation, and cardiac mural thrombus. For arterial thrombosis, hypertension, diabetes mellitus, and smoking are risk factors. Venous thrombosis is linked to splenectomy, portal hypertension, septic thrombophlebitis, and heart failure.
Epidemiology
Depending on the cause. more typical among older people.
H HISTORY
severe, intense stomach pain from colickiness. possibly accompanied by rectal bleeding or vomiting.
Past medical history of persistent mesenteric artery insufficiency, including significant weight loss and pain in the abdomen after eating. past liver or heart illness.
History and Examination
diffuse soreness and distension in the abdomen. a sensitive, palpable mass if a hernia is present. There could be no bowel sounds. unequal level of cardiovascular breakdown.

Intestinal Ischemia
- Published on
Surgery - intestinal Obstruction
Introduction
obstruction of the bowel's regular flow of contents. categorized by site: simple or strangulated, partial or whole, small or big bowel (SBO or LBO).
Etiology
Bowel blockage without vascular impairment is known as simple obstruction. Bowel above the obstruction dilates with gas and fluid, whereas the intestine distal to the obstruction quickly empties and collapses. Distension impairs the blood supply to the intestinal wall, increasing the risk of bowel perforation and mucosal ulcers.
Strangulated obstruction: When the blood supply to the afflicted segment is cut off, the usual mucosal barrier is weakened, bacteria can penetrate into the peritoneal cavity and cause peritonitis. If the intestine is left untreated, it can develop gangrene and burst.
The obstruction's cause is divided into the following categories. Extramural: External compression caused by a space-occupying lesion, bands, hernias, volvulus.
Intramural: Tumors, inflammatory strictures (such as those associated with diverticulitis or Crohn's disease), and intussusception.
Intraluminal: fecal impaction/constipation, worm infestation, pedunculated tumors, foreign objects (bezoars, gallstones), etc.
Epidemiology
Typical. more prevalent in older people as a result of an increase in adhesions, hernias, and cancer.
History
Severe, clenching, colicky pain in the lower abdomen (large intestine) or central abdomen (small intestine), that sometimes eases.
stomach distension.
Greenish-stained vomit that frequently comes up, either early in SBO or late with faeculent vomiting in distal SBO or LBO.
total constipation, defined as the inability to move gas or stool.
Examination
stomach distension accompanied by widespread soreness.
Peristalsis is observable.
bowel noises, or "tinkling" as they are called. Guarding and rebound indicate the development of peritonitis, and there may not be any bowel sounds.
Check for any hernias. Adhesions are a potential with any abdominal scarring.
Look for any masses in the abdomen (such as those caused by faecal impaction, cancer, intussusception, or a mass in the Douglas pouch).
Investigational studies
Blood: ABG: Lactic acidosis may indicate imminent perforation and intestinal ischaemia.
A big bowel cancer may be indicated by microcytic anemia. For electrolyte imbalance and dehydration brought on by vomiting, use urea and electrolytes.
AXR: Aids in blockage localization and diagnosis. SBO is suggested by the central ladder pattern, which consists of dilated loops with valvulae conniventes spanning the entire bowel's breadth. LBO is suggested if the distended bowel is more peripheral and has haustrations that do not overlap the intestinal breadth. One can see the fluid levels.
Raise the CXR to rule out perforation.
Water-soluble contrast enema: Helps identify the obstruction's location in LBO.
Water-soluble follow-through for contrast: to look into the obstruction's level.
CT scan: Enables care to be planned in accordance with the cause and/or degree of obstruction, as well as its level, prior to surgery. It can show a perforation or metastases.
Management
General: Inserting a nasogastric tube, closely monitoring vital signs, fluid balance, urine output, and clinical condition; resuscitation with IV fluids and electrolyte supplementation. Gastrografin follow-through for adhesive blockage may have therapeutic as well as diagnostic purposes. It is believed that the hyperosmotic contrast will lessen intestinal wall oedema and ease the obstruction. An early surgery can be scheduled if the study points to a different diagnosis.
Acute obstructions may resolve with conservative therapy; if not, or if problems appear, surgical surgery should be performed.
Surgical: To treat the cause, a laparoscopy or laparotomy.may entail band division, adhesiolysis, or bowel resection with or without a stoma. In small-bowel resection, primary anastomosis; in large-bowel resection, Hartmann's operation or hemicolectomy with non-functioning stoma. Post-operative care in an ICU or HDU may be necessary.
Endoscopic: Stenting obstructing colonic tumors can be done as a palliative measure or as a preoperative measure to prevent the need for urgent surgery. Endoscopic treatment options for obstruction resulting from a sigmoid volvulus include the use of a flexible sigmoidoscope and the insertion of a flatus tube.
Complications
diarrhea, intestinal perforation, toxaemia, and necrosis of the ischemic colon wall.
Prognosis
Variable. based on the patients' overall health and the frequency of problems.

Surgery - Intussusception
Introduction
the process of an intestine segment, the intussusceptum, invaginating into the adjacent intestinal lumen, the intussuscipiens, with the potential to cause blockage or vascular compromise of the colon.
Etiology
<three years: Up to 90% of cases are idiopathic and are linked to lymphoid hyperplasia in Peyer's patches, Meckel's diverticulum, polyps, and hemorrhages.
Children: Henoch-Schönlein purpura, blood dyscrasias (caused by submucosal hemoglobinas), recent upper respiratory tract infections.
Child/Adult: About one-third of small-bowel cases and two-thirds of large-bowel cases involve a mass in the bowel wall or lumen, such as a polyp, tumor, or Meckel's diverticulum, that is caused by malignancy.
Epidemiology
The frequency is 1-3/1000. mostly affects children between the ages of three and nine months. uncommon among grownups.
H HISTORY
Children may experience sporadic episodes of intense stomach discomfort, frequently accompanied by limb cramping. It is reported that PR can pass bloody mucus that looks like "red currant jelly."
Later stages may have vomiting and distension, similar to intestinal obstruction. Adults may experience vague symptoms.
Examination
Traditionally, the right hypochondrium had a "sausage-shaped" bulk.
Pale, hypotensive, and tachycardic are signs of shock.
Abdominal distension and tinkling bowel noises are indicators of blockage.
Absence of bowel sounds, rebound, and abdominal guarding are symptoms of peritonism.
Pathogenesis
The gut exhibits aberrant telescoping and peristalsis due to a pathological "lead point." The most frequent location is the ileocolic junction, however ileo-ileal and colo-colic are also possible. If left untreated, bowel wall venous congestion and oedema can lead to infarction and perforation.
Investigational studies
AXR: May reveal signs of blockage or a lack of air in the right side of the colon.
Ultrasound: The intruded section manifests as a lump shaped like a target.
The traditional method of demonstrating intussusception is with contrast/air enema, where the contrast at the location resembles a "coiled spring." Therapy may result from this (see Management).
Blood: lactic acidosis-related ABG, G&S, U&Es, and FBC.
Management
Supportive measures include NG tube insertion if vomiting, analgesics, antibiotic cover, and IV fluid resuscitation.
Therapeutic enema: Barium, air, or saline can be used to reduce the invaginating segment back. Not recommended in cases of suspected tumor, peritonitis, or perforation.
Surgery: Done if an enema is unable to relieve the condition or if peritonitis is showing symptoms.
To lessen intussusception, the impacted bowel is gently moved. Resection of the affected segment is required if the implicated bowel is non-viable, cannot be shrunk, or Meckel's diverticulum is discovered. able could be carried out laparoscopically
Complications
can result in perforation, blockage, hemorrhage, and ischaemia.
Prognosis
In as many as 10% of pediatric instances, spontaneous decrease can happen. The rate of recurrence is 5–10%.
Good with quick care; if left untreated, could be lethal.

Surgery - Venous leg ulcers
Introduction
Eighty to eighty-five percent of leg ulcers are caused by venous insufficiency, which results in lower limb ulceration.
Etiology
The consequences of venous hypertension, stemming from either superficial or deep venous incompetence, include heightened tissue oedema, compromised microcirculation, and ultimately, tissue necrosis and ulceration. The "fibrin cuff" of tissue, white cell adhesion, and/or persistent inflammation due to ischaemia-reperfusion injury are some of the theories regarding the processes.
Epidemiology
Leg ulcers affect 1% of people in affluent nations, placing a significant strain on healthcare resources as people age and are more common in women than in men.
History
The symptoms of chronic venous insufficiency include weight gain, hurting legs, ankle swelling, skin abnormalities, itching, and ulceration. Identify the risk factors for peripheral vascular disease or deep vein thrombosis.
Examination
A venous ulcer's typical location is in the "gaiter area," which is above the medial malleolus. The majority of the time, ulcerations are shallow, have sloping margins, and are surrounded by pigmentation, atrophie blanche, varicose eczema, and lipodermatosclerosis. While the patient is standing, look for varicose veins. Find the ankle-brachial pressure index (ABPI) to check for peripheral artery disease that may be present concurrently. Vascular, diabetic, neuropathic, infectious, neoplastic, and arterial ulcers are among the differential diagnoses.
Investigational studies
Ankle-brachial pressure index (ABPI): ABPIs should be used to screen all patients for vascular disease. Modified compression may be an option for patients with an ABPI of 0.5–0.8, while patients with an ABPI of less than 0.5 should be referred or evaluated for the care of arterial insufficiency first. Microbiology swab: If discharge, erythema, cellulitis, or pyrexia are indications of an infection. If cytology or a biopsy raises any doubts regarding cancer.
Management
Multiple layers of compression, such as the Charing Cross four-layer bandage made of wool, crepe, elastic, and cohesive bandages, are used to treat venous hypertension. suggestions for moving and elevating the legs. Compression stockings stop recurrence after healing. Antibiotics ought to be saved for cellulitis-surrounded infected ulcers. Pentoxifylline might be a useful supplement. It has not been demonstrated that topical treatments, regular systemic antibiotics, or certain types of dressings enhance healing. Surgery: Varicose veins can be treated with endovascular or open surgery. According to the ESCHAR (Effect of Surgery and Compression on Healing and Recurrence) study, superficial vein surgery helps to prevent recurrence once it has healed but does not accelerate the healing process by compression. Skin grafting might be suitable for some patients.
Complications
Chronic wounds, infection, recurrence, and the emergence of cancer in ulcers that have been open for a long time (Marjolin's ulcer).
Prognosis
Frequently a persistent issue with erratic recovery times. Recurrence rates after healing are roughly 25% after a year and 33% after 18 months.

Surgery - Lipomas
Introduction
Lipomas are benign adipose tissue tumors that grow slowly. Multiple contiguous lipomas that deform tissues, such as those on the buttocks or, less frequently, the neck, are referred to as lipomatosis. categorized according to its location, such as subcutaneous, subfascial, or subsynovial.
Etiology
are most frequently seen in subcutaneous fat but can appear in any type of connective tissue. Histologically, lipomas are composed of adipose cell collections that are identical to normal adipocytes and are separated into enormous lobules by thin fibrous septa.
Some chromosomal abnormalities, such as the translocation of a gene on chromosome 12, have been linked to the cause, which is unknown. Multiple painful lipomas (adiposis dolorosa/Dercum's disease) are an uncommon manifestation.
Epidemiology
All ages; uncommon in children, primarily 40–60 years old. No preference for a gender.
History
The patient feels a lump that is normally harmless and gradually growing, unless there has been trauma. In that case, it may expand and become tender due to fat necrosis.
Examination
can happen anyplace that there are stores of adipose tissue, which is often the upper arm subcutaneous tissue. Variable size, frequently lobulated, typically oval or spherical (a helpful diagnostic trait). Although they are soft, non-tender, and compressible, they rarely change or become transilluminate.
Usually, the skin on top is normal. Palpable local lymph nodes are not desired.
Investigational studies
Usually not required; deeply positioned lipomas can be seen with MRI.
Management
Conservative: Shouldn't cause discomfort or deform look, it can be left alone.
Surgical: If uncomfortable or unappealing. Removeable with local anesthesia: To expose the lipoma, surgical incision is made over it; often, the lipoma can be gently milked out via the incision with minimal dissection by applying moderate pressure on the surrounding tissue. It is important to maintain hemostasis in the resultant cavity to prevent the formation of hemomas. Greater in size or located in more intricate locations, lipomas will require removal under general anesthesia.
Complications
Usually connected with their excision via surgery rather than the lipoma itself.
In the event of trauma, fat necrosis could occur.
Prognosis
Superb; lipomas typically do not progress to malignancy (liposarcomas typically develop from scratch, for example in the retroperitoneum).
