Kembara Xtra - Symptoms and Signs - Localized Acute Abdominal Pain
The patient who comes into the clinic complaining of severe stomach discomfort is a typical example of a clinical issue that is of the utmost importance. However, for the purpose of this discussion, we will focus on individuals who report discomfort that is confined to a specific region within the abdominal cavity. This can be felt anywhere along the abdominal wall. The causes are numerous, and it is a productive exercise to compile a list of the organs that may be involved together with the pathological processes that are specific to each organ. This allows the clinician to explore the possibilities in a manner that is consistent with logic: 1. Gastroduodenal • Perforated gastric or duodenal ulcer • Perforated gastric cancer • Acute gastritis (frequently associated with alcohol consumption) • Irritant poisons 2. Intestinal Small-bowel obstruction (adhesions, etc.) Regional ileitis (Crohn's disease) Intussusception Sigmoid volvulus Acute colonic diverticulitis Large-bowel obstruction due to neoplasm Strangulated external hernia (inguinal, femoral, umbilical) Acute mesenteric occlusion due to arterial embolism or thrombosis or to venous 3. Appendix • Acute appendicitis 4. Pancreas • Pancreatic traumatic injury • Acute pancreatitis • Recurrent pancreatitis 5. Cholecystitis, acute cholecystitis, calculus in the gallbladder or common bile ducts, acute cholecystitis, and acute cholangitis are all conditions that can affect the gallbladder and bile ducts. 6. Liver; Trauma; Acute hepatitis; Malignant illness; Congestive heart failure; 7. Diseases or injuries to the spleen, such as malaria or infectious mononucleosis; ruptures that occur on their own; infarctions. 8. Renal trauma; calculus in the kidney, ureter, or vesicles; pyelonephritis; pyonephrosis; urinary tract; pyelonephritis; pyonephrosis 9. Conditions affecting the female genitalia, including salpingitis, pyosalpinx, ectopic pregnancy, torsion of subserous fibroid, red degeneration of fibroid, twisted ovarian cyst, ruptured ovarian cyst, and salpingo-oophorectomy. 10. Ruptured aneurysm of the aorta and dissecting aneurysm of the aorta It is vital to keep in mind that acute localized pain may be referred to the abdomen from various structures, in addition to the reasons that originate from within the abdominal cavity, retroperitoneal structures, and the pelvic organs. Herpes zoster, affecting the lower thoracic regions, is a condition that affects the central nervous system. Pain in the posterior nerve root (for example, as a result of a prolapsed intervertebral disc or depressed vertebra as a result of trauma or subsequent deposits) 12. Conditions affecting the heart and pericardium including: myocardial infarction, acute pericarditis 13. Pleura • Acute diaphragmatic pleurisy individuals who appear with simulated acute abdominal pain owing to hysteria or malingering are observed on occasion at the Accident and Emergency Department. These individuals are typically well-known in the department. Patients who are experiencing acute abdominal discomfort provide the clinician with one of the most difficult challenges. First and foremost, the diagnosis is of the utmost significance since it is necessary to determine whether or not the patient needs an emergency laparotomy. This may be the case, for instance, in the case of a ruptured peptic ulcer, acute appendicitis, or severe intestinal obstruction. Both the history and the examination can be challenging to get, but this is especially true in the case of a critically ill patient who is in a great deal of discomfort and has little desire either to answer a large number of questions or to submit to an in-depth examination. In conclusion, there are only a limited number of diagnostic tools available in the laboratory and through radiology. There is no one test that can diagnose acute appendicitis, for instance. There is a correlation between an increased white blood cell count and an intraperitoneal infection; nevertheless, there are cases of acute appendicitis in which the white blood cell count is less than 10,000 per mm3 in approximately one fourth of the cases. There is a possibility that liberated gas will be seen on a plain X-ray of the abdomen when there is a perforated hollow viscus, but this is not always the case (Fig. A.1). On a plain X-ray of the abdomen, distended loops of bowel may be seen if there is an obstruction in the intestines. However, in about 10% of cases of small-bowel obstruction, the X-rays appear completely normal. This is because the distended loops of bowel are filled with fluid only, rather than gas, and therefore do not have the appearance that is typical of gas distended loops of bowel. Abdominal ultrasonography can be used to demonstrate a diseased appendix, intussusception, distended loops of bowel, fluid collections, gallbladder pathology, the presence of gallstones, and swollen loops of bowel that have caused intussusception. However, a correct diagnosis is greatly dependent on the observer, and it is necessary to seek the assistance of an experienced ultrasonographer. When it is performed, computed tomography (CT) can also be of tremendous value. A increased serum amylase activity is one of the few laboratory studies that the surgeon places a significant amount of weight on. It is almost pathognomic of acute pancreatitis when this is above 1000 units per 100 ml serum; nonetheless, a fulminating case of pancreatitis is encountered every once in a while in which the amylase is not raised. Unfortunately, over 200 distinct test techniques for the measurement of amylase have been described. As a consequence of this, various hospitals may very likely have distinct reference ranges for what constitutes normal serum amylase levels. Because of this, it is absolutely necessary to be familiar with the usual reference range of serum amylase at your own hospital rather than attempting to recall values that are applicable at other hospitals. In cases of acute pancreatitis and pancreatic damage, a very high serum amylase value is often detected; nevertheless, a moderate rise may occur in cases of nonpancreatic acute abdominal disease (for example, a ruptured peptic ulcer, intestinal blockage, or infarction). The kidneys are responsible for clearing amylase from the circulation. Anything that disrupts the kidneys' normal ability to clear amylase may therefore also result in a slight increase in the level of amylase in the blood. Because of this, it is imperative that every effort be made to establish the diagnosis by meticulous history taking and physical examination. The formation of a trend is an essential step in doing an evaluation of an acute abdomen, and it is also one of the most time-consuming steps. Pain, tenderness, guarding, or rigidity that is increasing with time are all symptoms that point to the presence of a developing intraabdominal disease. This is also suggested by a growing pulse rate on hourly or half-hourly observations, and it is also suggested by a gradual increase in temperature. Additionally, this is suggested by the progression of an increase in the blood pressure. Repeated clinical examinations, in conjunction with consecutive recordings of the patient's temperature and pulse, will help the clinician to determine, in a case where the diagnosis is uncertain, whether the intra-abdominal state is getting better or getting worse. General Features An overall examination of the patient is of utmost significance and must under no circumstances be skipped. Patients with acute appendicitis will have a reddened face and a coated tongue. Patients with perforated ulcers will have an agonized look, and patients with ureteral stones, biliary colic, or small intestinal blockage may writhe in pain. All of these symptoms are quite helpful. The patient's skin is scrutinized for the jaundice that may be linked with biliary colic caused by a stone impacted at the lower end of the common bile duct as well as the pallor that is indicative of a possible hemorrhage. In this scenario, there will also be bile pigment that may be identified in the individual's urine. ABDOMINAL EXAMINATION The patient needs to be positioned in an area with enough lighting, and the entire abdominal region, from the nipples to the knees, needs to be visible. It is necessary to examine the abdomen. The absence of movement in conjunction with respiration can indicate that there is an underlying peritoneal irritation. Intestinal obstruction causes abdominal distension, and in these kinds of cases, visual peristalsis may be observed as the result of rhythmic contractions of the small bowel. In acute peritonitis, the abdomen may retract, giving the patient the impression of having a scaphoid shape. This may happen, for example, after a peptic ulcer perforates and causes bleeding into the abdominal cavity. When palpated, guarding, which is a voluntary contraction of the abdominal wall, is indicative of an underlying inflammatory condition. This is followed by localized discomfort in the area. Rigidity is characterized by an involuntary tightening of the abdominal wall, which can either be universal or localized. Rigidity can occur anywhere along the abdominal wall. In cases of acute appendicitis or acute cholecystitis, for example, the presence of localized rigidity over the affected organ signals the presence of local peritoneal involvement. The abdominal area can be usefully percussioned. A dullness in the flanks is indicative of the presence of intraperitoneal fluid, such as blood in a patient whose spleen has ruptured and caused bleeding into the abdominal cavity. When there is obstruction, the abdomen will have a resonant distended appearance, and the loss of liver dullness may indicate the presence of free gas within the peritoneal cavity in a patient who has a ruptured hollow viscus. When there is a blockage in the digestive tract, the sounds of the intestine are amplified and take on a distinctive 'tinkling' quality. Borborygmi may be audible even without the use of a stethoscope under some circumstances. Peritonitis may be suspected when there are no bowel noises audible at all. Once the hernial orifices have been thoroughly examined and palpated, the examination of the abdominal cavity will be considered to be complete. It is not difficult to miss a minor strangulated umbilical, femoral, or inguinal hernia, which, shockingly enough, may have been completely unnoticed by the patient. This can happen in any of these three locations. After that, a rectal examination will be carried out. Although the actual process that causes the rectum to have this characteristic 'ballooned' and empty feel in intestinal obstruction is unknown, the condition is characterized by it. There will be soreness anteriorly in the pouch of Douglas when a patient has pelvic peritonitis. It is possible to ascertain that an inflamed or twisted pelvic organ is the cause of a sensitive mass in the vagina by doing a bimanual examination. INVESTIGATIONS RELATING TO THE URINE AND OTHER SPECIAL THINGS When comparing a renal or biliary colic to other potential causes of intra-abdominal discomfort, the presence of blood, protein, pus, or bile pigment in the urine may be helpful in making the distinction. In addition to the standard analysis of a urine sample, a valuable test can be performed by placing a droplet under a microscope and observing it through a 1/6th lens; staining the sample beforehand is not necessary. Checking to see if pus cells or red cells are visible takes only a few minutes of work on your part. Porphyria should be ruled out in mysterious cases of stomach discomfort by testing the urine for porphyrins. This is especially important in situations where barbiturates appear to have been a contributing factor in triggering the attack. Laboratory and radiographic studies may be used to enhance the clinical assessment of a patient who is experiencing acute localized abdominal discomfort. The clinical assessment is mostly based on a comprehensive history and examination of the patient, as well as an analysis of the urine. In cases when pancreatitis is suspected, it is possible that a full blood count, a plain X-ray of the abdomen, and an assessment of the serum amylase will all be helpful. However, it is important to remember that the findings need to be interpreted with extreme caution. Urinary beta human chorionic gonadotrophin (beta hCG) is found to be positive in cases when it is thought that an ectopic pregnancy has burst. In cases where a twisted ovarian cyst or another form of pelvic pathology is suspected, an ultrasound of the pelvis can be of great assistance. In acute cases of cholecystitis, ultrasonography might be helpful in demonstrating the presence of gallstones. When there is a possibility of a stone in the ureter or another form of renal pathology, an urgent intravenous urogram should be performed. If it is thought that the upper belly pain is caused by a myocardial infarction, then an EKG and the proper cardiac enzyme estimations will be done on the patient. Additionally, a chest X-ray may show that the patient has a basal pneumonia. It is very helpful to demonstrate the oedematous and enlarged pancreas that occurs with acute pancreatitis through the use of computed tomography. However, it is imperative that this point be emphasized that the clinical aspects should be given priority above any and all other diagnostic aids. It's possible that diagnosing a patient with the so-called "acute abdomen" is both the easiest and most difficult medical challenge possible. Infants, where obtaining an exact history may be difficult and evaluating a crying child may be the most demanding, and the elderly, where, once again, it is frequently difficult to obtain an accurate history and where physical indications are frequently uncommon, are both likely to present with their own unique set of challenges. People who are morbidly obese and women who are pregnant are two other groups that are at a higher risk of experiencing unique challenges. When dealing with a patient who is experiencing significant abdominal discomfort, the primary choice that needs to be made is, of course, determining whether or not an emergency laparotomy is required to investigate the situation. In the event that rigorous evaluation still renders the decision challenging, it is necessary to carry out repeated observations over the course of the following few hours in order to monitor the development of the specific instance. This will almost always make it possible to arrive at a conclusive choice regarding whether or not a laparotomy or additional conservative treatment is necessary.
