In the majority of patients in this series of 1,000, acute abdominal pain was due to conditions that required neither surgical intervention nor hospitalization. Eleven of the 1,000 patients had an early missed diagnosis in the emergency clinic for which a subsequent operation was needed, and twenty underwent an operation which subsequent diagnosis showed was not required. All false-negative evaluations occurred in patients with early appendicitis or small bowel obstruction. Most false-positive results were due to acute infections of the female genitourinary tract in patients operated on to exclude appendicitis or a tubo-ovarian abscess. The following factors help identify the high risk patient with an acute surgical abdomen: (1) pain for less than 48 hours; (2) pain followed by vomiting; (3) guarding and rebound tenderness on physical examination; (4) advanced age; (5) a prior surgical procedure. The presence of these features demands careful evaluation and a liberal policy of admission and observation. White blood cell counts, body temperature, and abnormal abdominal roentgenograms may add confirmatory evidence but are not particularly helpful as screening devices.

Between 1 January 1988 and 31 December 1989, 525 patients were admitted to one hospital with a diagnosis of acute abdominal pain. Of these, 182 (34.7%) underwent an emergency operation and 14 (7.7%) of these patients subsequently died within 30 days. Death was due to intestinal obstruction in 69%, and there was a 28% mortality rate for emergency colonic resection. Non-specific abdominal pain (NSAP) was the most common diagnosis (36.0%), followed by appendicitis (14.9%) and urological causes (12.8%). There was an unnecessary appendicectomy rate of 25.0%. Admission with pain because of urological causes was over twice that of previous reports. Duration of stay increased greatly with age. Results from this study confirm the high mortality rate in the elderly from emergency colonic resection. Greater care in diagnosis and a conservative approach to appendicitis, with laparoscopy in females of reproductive age, may produce a lower unnecessary appendicectomy rate without an increase in morbidity. If the diagnosis of NSAP could be made earlier and patients discharged sooner, a large saving in resources would result. This early diagnosis is not yet possible.

Crohn's disease of the small intestine is usually managed by medical therapy with surgery being reserved for obstruction or fistula formation. A patient is described who developed small bowel obstruction due to an adenocarcinoma of the ileum after over twenty years of medical therapy for Crohn's disease, originally diagnosed at a laparotomy for acute abdominal pain. The possibility of malignancy in such long-standing disease should be considered.

The presentation, operative management and final diagnosis were reviewed in 28 patients with AIDS (27 men and one woman) who underwent emergency laparotomy. On clinical and radiological examination, six patients showed features of toxic megacolon, five patients had small bowel obstruction, six patients had localized peritonitis and three had perforated viscus with generalized peritonitis. The most common disease processes were acute colitis in seven patients (associated with cytomegalovirus (CMV) infection in six), intra-abdominal lymphoma in five patients, acute appendicitis in five patients (associated with CMV infection in two), and atypical mycobacterial (MAI) infection in four patients. Two perioperative deaths occurred; one in a patient with acute pancreatitis and a second with generalized peritonitis. Later deaths were due to progression of AIDS, and patient survival at 1 month, 3 months and 6 months was 89 per cent, 64 per cent and 48 per cent, respectively. Lower operative mortality than in previously reported series may be due to earlier intervention in CMV toxic megacolon. Surgery, however, conferred less benefit in patients with acute abdominal pain from MAI infection or lymphoma. With careful patient selection, emergency laparotomy may achieve worthwhile palliation in patients with AIDS.

Meckel's diverticulum occurs in 2% of the population and may present at any age. Its management, when found incidentally at laparotomy, remains controversial, particularly in the pediatric population. From 1970 to 1989, a Meckel's diverticulum was discovered in 164 children at laparotomy. There were 120 boys and 44 girls with a mean age of 5.2 years (range, 0 to 18 years). Forty-seven cases were asymptomatic, representing an incidental finding at laparotomy, 25 were resected, and ectopic gastric mucosa was present in 7 specimens (28%). Three postoperative deaths (6%) that were not related to the resection and 2 complications (4%) (postoperative leak and wound infection) occurred in this group. Of the 117 symptomatic patients, 49 (42%) presented with bowel obstruction, 45 (38%) had rectal bleeding, 16 (14%) had diverticulitis, and 7 (6%) had umbilical pathology. Volvulus (20) and intussusception (19) were the most common causes of obstruction. Predisposing factors for bowel obstruction were fibrous bands to umbilicus or mesentery (37%) and ectopic mucosa (35%). Severe painless rectal bleeding occurred in 45 patients, 30 of whom (67%) required blood transfusion. A nuclear medicine Meckel scan was positive in 32 of 37 patients (85%). Contrast studies were not diagnostic; colonoscopy and gastroscopy ruled out other causes of bleeding. Patients with diverticulitis (16) presented with acute abdominal pain compatible with appendicitis. In the symptomatic group, ectopic mucosa was present in 61% of the resected specimens. Gastric (88%), pancreatic (7%), and gastric with pancreatic (3%) were the most common ectopic tissue. Postoperative morbidity and mortality for symptomatic patients was 8.5% and 0%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Intestinal obstruction owing to colonic carcinoma is a relatively frequent cause of acute abdominal pain. The aim of this prospective study is to evaluate the prognostic factors that may influence the final outcome of those patients operated upon for an intestinal obstruction (OG) as opposed to those electively operated upon (EG). From September 1984 to March 1988, a total of 188 patients with colorectal cancer have been included in the study. One hundred thirty-five were EG, while 53 (28.1 percent) were OG. The mean ages were similar in both groups. Sex, morbidity, and mortality rates were equally distributed. Curative resection rate was significantly higher in the EG group (P = 0.029). Tumor staging tended to be significantly more advanced in OG patients (chi-square = 9.054; df = 3; P = 0.026). Multivariate analysis (proportional hazards model) showed that the only independent prognostic factor was tumor staging (P = 0.0000). Obstruction itself disappears as a predictive variable when tumor staging is introduced in the model. We conclude that obstructing colon carcinomas tend to be more locally advanced, that probably being the only reason for a worse long-term prognosis.

Plain abdominal radiographs are rarely diagnostic when the patient presents with acute abdominal pain. Emergency physicians, therefore, should be aware of the appropriate indications and limitations of abdominal films in this setting and should be skilled in their interpretation to exclude the rare cases of pneumoperitoneum, pneumobilia, hepatic-portovenous gas, small and large bowel obstruction, toxic megacolon, volvulus and intramural gas.

Acute abdominal pain continues to provide not only a large workload for the general surgeon but also many diagnostic and management problems. Many different techniques have been introduced over the past two decades to help in the management of the acute abdomen and this review considers their relative claims to become incorporated into the process of clinical decision-making. The evidence in support of formally structured patient interview pathways with or without computer-aided diagnostic programs is now overwhelming and should become routine. Both laparoscopy and peritoneal cytology have an important role to play in the management of patients in whom the decision to operate is in doubt, and a combination of the two would be complementary. Ultrasonography has become increasingly popular for investigating the acute abdomen, and results from specialist centres are impressive. However, the problems of operator variation and the difficulties in providing a 24-h service will probably prevent it from becoming a first-line investigation in most hospitals. Although plain radiography has been available for many years, its routine use in the management of the acute abdomen remains controversial. Recent studies have confirmed that contrast radiography is an important adjunct to decision-making, particularly in the management of large bowel obstruction, and there is increasing evidence to support its use in suspected small bowel obstruction, perforated peptic ulcer and acute diverticular disease.

Acute abdominal pain in the patient receiving oral anticoagulants poses a difficult diagnostic and therapeutic challenge. We describe two cases of peritonitis requiring laparotomy in anticoagulated patients, and review 49 similar case reports from the world literature. These patients were usually explored for signs of bowel obstruction. At operation, the intestine often appeared infarcted, but pathologic examination commonly revealed intramural hematomata. In contrast, we present microscopic evidence of hemorrhagic cecal infarction complicating oral anticoagulation therapy in one patient. Intramural intestinal hemorrhage is the most common cause of acute abdominal pain in the anticoagulated patient who undergoes laparotomy. In addition to intramural hemorrhage, 14 per cent of patients had coexistent volvulus, appendicitis, intestinal wall disruption or intestinal infarction. We conclude that anticoagulated patients with suspected intramural intestinal hemorrhage may have severe intraabdominal pathology requiring operation. Therefore, operation is mandatory for patients who fail to improve after a short course of expectant management.

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.
