Twelve children with acute abdominal pain, which was suspected of being acute appendicitis, were subsequently found to have lower lobe pneumonia. Diagnostic barium enema or operative exploration failed to demonstrate any appendiceal abnormality. The abdominal symptoms and the ileus subsided soon after the initiation of antibiotic therapy. Contrary to common belief, it was observed that left-sided pneumonia is capable of mimicking appendicitis almost as frequently as right-sided pneumonia. Since the likelihood of acute appendicitis accompanying pneumonia is small, operative intervention is rarely indicated and should be undertaken only after careful and intensive investigation.

A retrospective review of 1,220 cystic fibrosis (CF) patients between 1965 and 1989 identified 60 patients who underwent appendectomy. Ten had appendectomy prior to referral and 16 had an incidental appendectomy (primarily meconium ileus). Among the remaining 34 patients, acute appendicitis was present in 19 (1.8% incidence). "Classic appendicitis"--acute abdominal pain shifting to the right lower quadrant (RLQ), focal RLQ tenderness, and elevated white blood cell (WBC) count--was present in 15. Four additional inflamed appendixes were removed in patients following incorrect preoperative diagnosis. Thirteen of these 19 were perforated. Complications included wound infection (2), pelvic abscess (1), ileal obstruction requiring ileostomy (1), and pelvic hematoma (1). There were no deaths. One patient with acute RLQ pain and tenderness had a normal appendix. Seven patients (mean, 20 years) had chronic, intermittent, focal RLQ pain and tenderness not originating periumbilically with a normal WBC count and temperature. At exploration, these appendixes were enlarged and tensely distended with inspissated mucus. Microscopic examination showed no inflammation. Appendectomy resulted in resolution of symptoms without complications. Four additional patients with intermittent RLQ pain and tenderness and a history of recurrent intussusception presented with ileocolic intussusception. Persistent postreduction symptoms in three and failure of reduction in the fourth necessitated celiotomy at which time tensely distended appendixes were removed. Appendectomy led to resolution of symptoms. Three additional enlarged noninflammed appendixes were incidentally removed in asymptomatic patients undergoing unrelated intraabdominal procedures. Appendiceal disease in CF patients represents a spectrum ranging from simple mucous distention to acute appendicitis with perforation. CF patients with pain secondary to a noninflamed distended appendix represent a distinct syndrome cured by appendectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Internal hernias are rarely diagnosed. Most of the times they are found at laparotomy when complications and their symptoms (for instance palpable tumour, abdominal pain, vomiting and ileus) require surgical treatment. We present a case of an eleven-year-old boy who was admitted to our hospital because of acute abdominal pain. Appendectomy brought only temporary relief of pain. Subsequent laparotomy yielded the diagnosis of left-sided paraduodenal hernia.

A woman of 60 years of age with acute abdominal pain, vomiting, constipation and radiological signs of small bowel obstruction was subjected to sonographic examination. Careful examination of the entire abdomen demonstrated a hyperechoic object within the distended terminal ileum with an intensive acoustic shadow. The gallbladder was not visible. This strongly suggested gallstone ileus, especially since the patient had a history of gallbladder disease. She was treated immediately by enterotomy and extraction of a noncalcified obstructing stone. The value of ultrasound in detecting gallstones causing small bowel obstruction is discussed.

2 cases of midgut infarction in patients taking oral contraceptives are reported. Case 1 was a 38-year-old married woman with 3 children. After 2 isolated bouts of severe abdominal pain and diarrhea, examination revealed only minimal epigastric and left loin tenderness. Blood counts were normal. Other tests were negative. She had been taking cyclical tablets of 2.5 mg norethynodrel and .1 mg mestranol (Con ovid-E) for 48 months and continued after 8 days in the hospital. 18 weeks later severe abdominal pain, vomiting, and diarrhea occurred with abdominal tenderness and rigidity. The white-cell count was 25,000 with 85-90% segmented forms. Other blood tests were normal. At operation the superior mesenteric artery was found to be occluded distal to the origin of the middle colic artery. The thrombus was removed and the circulation to the gut seemed adequate. Intravenous heparin was given. Reoperation at 12 and again at 36 hours revealed viable intestine. 8 days after hospital admission ileus symptoms occurred. Reoperation revealed gangrene of almost all of the small intestine and part of the large intestine. The patient died 3 days later. Autopsy showed thrombosis of the superior mesenteric artery which was apparently not associated with local atheroma. Minimal atheroma in the aorta and an infarct of the spleen were noted. Case 2 was a 45-year-old married woman with 2 children who complained of severe abdominal pain and vomiting of 8 hours duration. A similar attack 1 week earlier had subsided in 6 hours. She had been taking tablets of 5 mg ethinyl-esternol (lynestrenol) and .15 mg mestranol (Noracyclin) for 11 months. There was no fever. The white-cell count was 19,500 with 85% segmented forms. Other laboratory tests and X-ray were normal. A loud bruit was heard over the upper abdomen. Bowel sounds were hyperactive. A diagnosis of acute small-bowel obstruction was made. At operation a definite diagnosis could not be made. Symptoms became worse. Reoperation 10 days later revealed gangrenous small intestine and part of the large intestine. The gangrenous parts were removed. After a complicated convalescence the patient recovered, but has moderate steatorrhea. Histologic examination of the resected intestine showed no evidence of atheroma in the mesenteric vessels. Considering these 2 cases with premonitory warning symptoms and without evidence of an atheromatous cause but associated with oral contraceptive therapy the immediate discontinuance of such therapy in women who develop acute abdominal pain is irecommended.

A 45-yr-old male patient developed acute abdominal pain, ileus, and microscopic hematuria with biochemical evidence of pancreatitis and a marked increase in liver alkaline phosphatase; CT demonstrated swelling of the pancreas, bilateral adrenal hemorrhage, and a suggestion of renal hemorrhage. ERCP was negative and renal arterial and venous blood flow normal. A coagulation profile demonstrated the presence of lupus anticoagulant, but tests for anticardiolipin antibodies and collagen vascular diseases were negative. Treatment with corticosteroids and anticoagulation resulted in improvement in clinical and all biochemical indices. Thus, lupus anticoagulant syndrome may masquerade as an acute abdominal illness with multiorgan involvement.

From the surgical point of view acute abdominal pain is the cardinal symptom of acute abdomen. Additional leading symptoms of acute abdomen are tension of the abdominal wall, peristaltic disorders and, in rare cases, shock symptoms. Acute abdomen is an operational diagnosis for painful, in part life threatening diseases of various etiologies. The most frequent cause is acute appendicitis, followed by cholecystitis and by diverse forms of ileus. These three diseases together are the cause of acute abdomen in more than 80% of cases. Over 90% of cases with acute abdomen are treated surgically. The decision in favour of a surgical intervention must be determined within minutes to hours depending on the etiology. A delay may lead to further, partly most serious sequelae.

A 37-year-old woman underwent an emergency operation at our hospital because of severe abdominal pain and ileus. Most of her small intestine and ascending colon were observed to have become necrotic due to occlusion of her superior mesenteric artery (SMA). Pathological findings of the resected intestine revealed that her SMA was completely thrombosed 2 cm distal from its origin with smooth muscle proliferation. Post-surgical blood analysis of her pre-operative serum was positive for lupus anticoagulant and antinuclear antibodies. She noticed vaginal bleeding due to missed abortion on the 31st day after the operation. We diagnosed her acute abdominal pain to be that of antiphospholipid syndrome associated with her pregnancy.

We report herein the case of an 81-year-old woman found to have small intestinal carcinoma producing carbohydrate antigen (CA)19-9, in whom recurrence on the abdominal wall was strongly suspected 4 months after resection. She presented to our hospital with acute abdominal pain with severe anemia. Marked serum elevation of CA19-9 to 164.8 U/ml suggested a progression to malignancy. A fluorography using an ileus tube revealed an abnormal mucosal pattern. An exploratory laparotomy showed an incomplete annular constrictive Borrmann type 2 tumor, located approximately 190 cm from Treitz's ligament, without any signs of peritoneal or hepatic metastases. Histological examination confirmed a diagnosis of papillotubular adenocarcinoma without metastases of the regional lymph nodes. CA19-9 antigenicity was detected in the cytoplasm and on the surface of the cancer cells, using the monoclonal CA19-9 antibody, NS19-9. In this report, we demonstrate the CA19-9 productivity and distribution of the cancer tissues in relation to their prognosis.

A 43-year-old woman presented with acute abdominal pain and signs of ileus. CT scan of the abdomen showed hepatic portal venous gas. At surgery, a long segment of gangrenous bowel extending from the jejunum to the proximal hemicolon was found. The cause was superior mesenteric artery occlusion. The aetiology, imaging features and clinical significance of hepatic portal venous gas are discussed.
