Randomised assessment of new laparoscopic surgical techniques is difficult. Surgeons need time to become experienced with the methods and tend, when they have experience, to favour one or other approach. We have carried out a prospective randomised comparison of laparoscopic and conventional appendicectomy done by surgeons of comparable experience in patients with suspected acute appendicitis. Postoperative management decisions were made by surgeons other than the operating surgeon. 140 patients were randomly assigned to open (OA) or laparoscopic (LA) appendicectomy (70 each). The age, sex ratio, duration of symptoms, and proportion of patients with histologically confirmed appendicitis was similar in the two groups. Operating time was longer for LA than for OA (mean 70.3 [SD 21.9] vs 46.5 [25.9] min; p < 0.001). There were no major intraoperative complications in either group. 14 (20%) patients in the LA group required conversion to an open operation. No significant differences between the groups were found postoperatively for pain score, analgesic requirement, time to reintroduction of diet, or hospital stay. 46 LA patients and 42 OA patients attended follow-up 3 weeks after surgery. Similar proportions had returned to work (36 [79%] vs 31 [74%]). The frequency of wound complications and wound pain after leaving hospital was lower after LA but not significantly so. We conclude that the postoperative course after LA and conventional OA does not differ significantly.

The clinical safety and efficacy of imipenem/cilastatin in the treatment of intra-abdominal infections was compared with the combination of aztreonam and clindamycin in a randomized prospective trial. The severity of illness was determined by means of the Apache II score and a fixed outcome reporting scheme was used. One hundred and four patients were entered into the study, of whom 80 were evaluable. Forty-two patients were treated with imipenem/cilastatin (500 + 500 mg qds) and 38 with aztreonam (600 tds) and clindamycin (1000 mg tds). The study groups were comparable for age and sex. The imipenem/cilastatin group differed from the aztreonam and clindamycin group in having significantly more patients with the diagnosis of acute appendicitis (P < 0.01) and a significantly lower mean Apache score (P < 0.05). The predominate microorganisms isolated in both groups were Escherichia coli and Bacteroides fragilis. Treatment with imipenem/cilastatin proved successful in 71% and failed in 24%, and initial success only was seen in 5%. The numbers in the group treated with aztreonam and clindamycin were 64%, 29% and 7% respectively. Severity of illness, as measured by Apache II score, had no influence on the study outcome. Imipenem/cilastatin as well as the combination of aztreonam and clindamycin were effective in the treatment of abdominal infections and no major adverse reactions were seen.

To assess the risks of adverse outcomes after appendectomy incidental to cholecystectomy among elderly Medicare beneficiaries, 8,936 persons undergoing cholecystectomy with incidental appendectomy and 44,461 persons undergoing cholecystectomy without incidental appendectomy were studied. Controlling for age, race, gender and co-morbidity status, the risk for wound infection in persons with incidental appendectomy was 83 percent higher than in persons without incidental appendectomy (95 percent confidence interval, 1.53 to 2.18). The risks for having other adverse outcomes, including other infections, extensive intrahospital complications and mortality rate at 30 days, were also higher for the former group, although these differences were not statistically significant. In addition, the demographic characteristics and health status of persons undergoing cholecystectomy with incidental appendectomy with persons undergoing cholecystectomy only were compared. Males, persons of younger ages, of white race or with no co-morbid conditions, were significantly more likely to undergo cholecystectomy with incidental appendectomy. Variables to control for differences in the demographic characteristics and health status between persons receiving and not receiving incidental appendectomy were included in the regression models for adverse outcomes. However, these models may not completely control for differences between the two groups. As a result, the actual relationship between incidental appendectomy and adverse outcomes may be underestimated. The preventive effect of incidental appendectomy on morbidity and mortality rates from future instances of appendicitis was assessed by determining the remaining lifetime risk for acute appendicitis. For persons 65 to 69 years of age, 115 incidental appendectomies would be required to prevent one future instance of appendicitis and 4,472 incidental appendectomies would be needed to prevent a single future death from acute appendicitis. Because incidental appendectomy increases the risk for wound infection among persons undergoing cholecystectomy and because the lifetime risk for acute appendicitis is relatively low for persons of this age group, surgeons should carefully consider the risks and benefits of incidental appendectomy in the elderly.

The patient with acute abdominal pain presents the attending physician with a wide and varied gamut of diagnostic possibilities. Prompt and accurate diagnosis is essential for the proper care and management of these acutely ill patients. Diagnostic radiology is often an integral part of the emergent evaluation of these patients. This article focuses on some of the key plain-film findings in the patients suffering from acute abdominal pain of intestinal causes and reviews the radiologic evaluation of several major abdominal conditions such as acute appendicitis, diverticulitis, inflammatory bowel disease, bowel ischemia, and infarction.

To understand the surgical approach to acute abdominal pain, the internist must be familiar with common presentations of most abdominal emergencies; these emergencies include acute appendicitis, acute gall bladder disease (biliary colic, acute cholecystitis, and acute pancreatitis), ischemic bowel disease and ischemic colitis, abdominal aortic aneurysm, and intestinal obstruction. Nothing compares to experience; this article reviews the salient points that deserve consideration.

Acute appendicitis is rarely the initial presentation of carcinoma of the cecum in elderly patients. A 20-year retrospective review of all patients 65 years of age or older presenting with proven acute appendicitis at the Montefiore Medical Center confirms this opinion. In only 1.8% of patients was acute appendicitis the initial presentation of an underlying carcinoma of the cecum.

We report a case of a 28-year-old female, Grava 2, Para I, Ab. 0, who presented acute abdominal pain on the 21st week of her gestation. A diagnosis of acute appendicitis was entertained and an appendectomy performed. The pathologic specimen revealed an inflamed appendix with endometriosis and a marked decidual reaction. A decidual polyp, which occluded most of the appendiceal lumen, is proposed as a rare cause of acute appendicitis during pregnancy.

A study was carried out on 366 female patients admitted consecutively to Asir Central Hospital with clinical diagnosis of acute appendicitis during the period between 1988 through 1991. In this study, 271 patients had histopathologically proven appendicitis for a diagnostic accuracy of 74%. Ninety-five (26%) patients did not have appendicitis, however, 27 (7.4%) of them had other disorders indicating surgical intervention. Consequently, 18.6% of the patients studied had negative laparotomy. This study showed insignificant (P > 0.05) relation between age, site of pain and its duration, presence of urinary symptoms, post-operative complications and hospitalization in one hand, and the final diagnosis on the other hand. The marital status, the presence of gynaecological symptoms, white blood cells count, neutrophils and lymphocytes percentages were, however, significantly related to the final diagnosis (P < 0.05). A conservative approach with in-hospital observation and repeated clinical examination of the doubted appendicitis cases are recommended so as to reduce the rate of the negative laparotomy with its considerable complications.

Ascariasis is a helminthic infection of global distribution with more than 1.4 billion persons infected throughout the world. The majority of infections occur in the developing countries of Asia and Latin America. Of 4 million people infected in the United States, a large percentage are immigrants from developing countries. Ascaris-related clinical disease is restricted to subjects with heavy worm load, and an estimated 1.2 to 2 million such cases, with 20,000 deaths, occur in endemic areas per year. More often, recurring moderate infections cause stunting of linear growth, cause reduced cognitive function, and contribute to existing malnutrition in children in endemic areas. Ascaris infection is acquired by the ingestion of the embryonated eggs. The larvae, while passing through the pulmonary migration phase for maturation, cause ascaris pneumonia. Intestinal ascaris is usually detected as an incidental finding. Ascaris-induced intestinal obstruction is a frequent complication in children with heavy worm loads. It can be complicated by intussusception, perforation, and gangrene of the bowel. Acute appendicitis and appendicular perforation can occur as a result of worms entering the appendix. HPA is a frequent cause of biliary and pancreatic disease in endemic areas. It occurs in adult women and can cause biliary colic, acute cholecystitis, acute cholangitis, acute pancreatitis, and hepatic abscess. RPC causing hepatic duct calculi is possibly an aftermath of recurrent biliary invasion in such areas. Ultrasonography can detect worms in the biliary tract and pancreas and is a useful noninvasive technique for diagnosis and follow-up of such patients. ERCP can help diagnose biliary and pancreatic ascariasis, including ascaris in the duodenum. Also, ERCP can be used to extract worms from the biliary and pancreatic ducts when indicated. Pyrantel pomoate, mebendazole, albendazole, and levamisole are effective drugs and can be used for mass therapy to control ascariasis in endemic areas.

Metastatic tumors to the appendix are not common. However, these tumors should be one of the differential diagnoses in patients with known primary malignancy, who present with signs and symptoms of acute appendicitis. We report a case of an elderly male with poorly differentiated bronchogenic adenocarcinoma which metastasized to the appendix.
