A laparotomy was performed on a 44-year-old male patient with an acute abdomen who had findings suggestive of acute appendicitis and a periappendicular abscess. A histopathological examination revealed a carcinoid tumor infiltrating the intestinal serosa. The distal ileum and cecum were infiltrated with more than 40 multifocal tumors, with the largest measuring 1 cm in size. The distal ileum and cecum were resected. We failed to find any distant metastases either peroperatively or during postoperative scintigraphic tests. In addition, the patient had no symptoms of carcinoid syndrome either before or after surgery. No recurrence was experienced. We thus conclude that primary multifocal carcinoid tumors may act as a solitary carcinoid tumor, and the largest tumor tends to indicate the overall clinical outcome.

Salmonella spp. infections can be particularly challenging when they manifest as acute abdominal problems and lead to emergency surgery. Examples of such serious conditions are Salmonella-related intestinal perforation, gallbladder involvement, salpingitis, and peritonitis. Mesenteric lymphadenitis associated with Salmonella typhimurium mimics acute appendicitis and can make it difficult to establish a timely and definitive diagnosis in young patients who present with right lower abdominal pain. Paralytic ileus is a fairly common manifestation of Salmonella infection at all ages, but complete intestinal obstruction requiring surgical intervention is very rare. Because of the nature of the diagnostic process, a significant number of patients with Salmonella infection present with acute abdomen and undergo needless operations. This report describes the cases of 2 pediatric patients who underwent surgery to address persistent pain in the right lower abdominal quadrant and complete intestinal obstruction, respectively. The first patient had inflamed mesenteric lymph nodes that caused appendicitislike symptoms, and the second had dense adhesions between the mesentery and the terminal segments of the ileum that led to intestinal blockage. Serology results showed that both patients' titers for BO ("B and O agglutinating [BO]") antibodies rose to 1:640 in the week after their admission to hospital, a pattern and level that is indicative of S typhimurium infection. J Pediatr Surg 36:1849-1852.

The increasing use of sonography for evaluating acute abdomen has brought greater recognition of appendicular abnormalities. We present an incidental finding of an appendiceal diverticulum during a sonographic examination of a 4-year-old child with acute appendicitis. Abdominal sonography showed an enlarged, swollen appendix with a diameter of 1.1 cm and a small, fingerlike lateral projection approximately 2.0 cm from its tip. The specimen, resected during an appendectomy, was 5.5 cm long and 1.0 cm in diameter and had a 0.3-cm outpouching. Microscopic examination revealed a pseudodiverticulum composed of mucosa and muscularis mucosa.

This is a review of the epidemiological, diagnostic and therapeutic aspects of acute abdominal conditions during pregnancy. We emphasize the recent changes in surgical criteria that have appeared since the advent of laparoscopic surgery. The incidence of acute appendicitis during pregnancy is 1 in every 1,500 while approximately 4.5% of pregnant women have asymptomatic cholelithiasis and 0.05% acute cholecystitis. Up to 40% of these patients will require surgery during gestation and it is well known that abdominal interventions in this period carry out a higher risk of miscarriage or premature labor. We analyze the most common causes of acute abdomen during pregnancy as well as the special considerations of conservative treatment, open surgery and laparoscopic surgery. We also review the technical aspects of laparoscopic procedures and the safety guidelines by the Society of American Gastrointestinal Endoscopic Surgeons. It is concluded that the laparoscopic approach is safe and effective in the diagnosis and treatment of acute abdominal pathology during pregnancy. The advantages over conventional open surgery have made many surgeons and gynecologists change their criteria in favor of laparoscopy and this is now often their first choice of treatment.

Torsions are rare acute abdominal conditions and are mistaken for other more frequent diseases. The present work draws attention to the most frequent diagnostic errors. The authors present three cases of torsions of intraabdominal organs and two cases of testicular torsion. All patients attended their doctor because of abdominal pain. In four of five cases the patients were first treated for an erroneous diagnosis of acute abdomen. In the first case the torsion of the omentum was mistaken for diverticulitis of the sigmoid, later for an intraperitoneal lipoma, in he second case for cholecystitis, in the third case a patient with torsion of a myoma was indicated for surgery on account of acute appendicitis. In the fourth case incomplete torsion of the testis was mistaken for irritation of the appendix. In the fifth case where abdominal symptomatology dominated the correct diagnosis of testicular torsion was made and atypically spontaneous detorsion of the testis occurred.

Laparoscopy, which has been well known as a diagnostic procedure for more than a century, has recently established itself as an important therapeutic procedure in several branches of surgery. In the present study the authors report on 221 patients over a 10-year period (1991-2001), admitted to hospital with a diagnosis of acute abdomen or abdominal trauma. All patients were submitted to emergency laparoscopic surgery; 128 patients (57%) presented acute appendicitis, 40 (18%) acute cholecystitis, 13 (6%) occlusive ileus, 10 (5%) adnexal pathologies, 9 (4%) perforation of abdominal viscera, 3 (1.4%) acute diverticulitis, 3 (1.4%) subdiaphragmatic abscesses, 3 (1.4%) intestinal infarction, 2 (0.8%) other diseases and 10 (5%) abdominal trauma. The operation was completed laparoscopically in 192 cases (87%), while conversion to laparotomy proved necessary in 29 cases (13%). The morbidity of the cases completed laparoscopically was 3%, the mortality 0.5%, and the mean hospital stay 4 days. Advantages of laparoscopy (shorter hospital stay, rapid postoperative recovery and faster return to social activities) emerge from the present study and are confirmed by the literature. The possibility of combining a diagnostic procedure with curative therapy suggests that laparoscopy may have an important role in emergency surgery, demonstrating its efficacy also in acute abdominal syndromes. Nevertheless, emergency laparoscopic surgery is still a technically difficult procedure that needs to be performed by an expert surgical team.

The era of videoendoscopic surgery in emergency surgery practice has facilitated a wide range of endoscopic operative procedures. In our unit the diagnosis of acute abdomen is made after sequential clinical and laboratory examination, and diagnostic laparoscopy is advocated. Laparoscopy-assisted resection of complicated Meckel's diverticulum in two adult patients was performed, and the results are discussed. Between December 1996 and June 2000, 98 patients underwent diagnostic laparoscopy at the Cerrahpasa Medical Faculty Emergency Surgery Unit of Istanbul University because of signs and symptoms of acute abdomen. Among these, we have diagnosed one case of intestinal obstruction due to a volvulus around Meckel's diverticulum and one of acute abdomen masquerading as acute appendicitis but actually involving omphalomesenteric duct cyst torsion. Both of these patients underwent diagnostic laparoscopy and laparoscopy-assisted Meckel's diverticulectomy. Diagnostic laparoscopies were performed on 46 male (47%) and 52 female (53%) patients. In all cases, laparoscopy successfully confirmed the diagnosis. Although in 27 patients the interventions were converted to open procedures, the operations were completed laparoscopically in 71 patients. Two of these patients underwent laparoscopy-assisted Meckel's diverticulectomy and their postoperative periods were uneventful. Both patients were discharged from the hospital on their fourth postoperative day. Diagnostic laparoscopy is a safe and effective method for diagnosis of acute abdomen. In emergency surgery practices in developing countries, advanced laparoscopy should be performed to reduce expenses. Laparoscopy-assisted Meckel's diverticulectomy is a safe and economic procedure and can be performed in adults for treatment of complicated cases without staplers.

Amoebiasis, a disease of worldwide distribution, is endemic in tropical countries with suboptimal sanitation facilities. Isolated amoebic appendicitis (IAA) is regarded as a rare manifestation of the disease globally. Because there are no defined clinical features that distinguish IAA from bacterial appendicitis, diagnosis is usually dependent on histopathological examination. A 9-year retrospective study was undertaken to investigate the clinicopathological aspects of IAA. The main complaints were fever and abdominal pain. None of the patients had dysentery. The pre-operative clinical diagnosis was acute appendicitis and acute abdomen in 13 and 8 patients, respectively. In all cases the intra-operative diagnosis was acute appendicitis. Gross pathological appraisal revealed peritonitis and perforation in 19 and 17 cases, respectively. Histopathological examination of these appendices demonstrated appendiceal ulceration, transmural mixed inflammation, haematophagous amoebic trophozoites and necrosis in all cases. Vascular pathology comprised venous and capillary luminal plugging (11 cases), necrotising small vessel vasculitis (11 cases), thrombophlebitis of medium sized veins (9 cases) and arteritis with associated thrombosis (1 case). Organising fibrinopurulent peritonitis was present in 19 cases. Two appendices that appeared normal macroscopically demonstrated ulceration and inflammation that were confined to the mucosa and submucosa. All of 18 patients who were treated with metronidazole survived without further surgery, while three patients who were untreated succumbed to the disease. Appendicectomy, accurate histopathological appraisal thereof and optimal, timely management of IAA were critical to the favourable outcome in the present study.

Isolated inflammatory alterations of the greater omentum are rare diseases. Since the preoperative diagnosis is difficult these changes are usually ascertained upon laparotomy. Between 1999 and 2001 four patients (44-88-years-old, 2 males) underwent laparotomy for an inflammatory tumor mass or an acute abdomen, respectively. C-reactive protein was elevated in all cases. In two cases a primary torsion of the greater omentum was found, in the other two a paracolic pseudotumorous omentitis. Resection of the diseased omental parts led to complete recovery. Torsion of the greater omentum and omentitis cause abdominal symptoms with an inflammatory component that often mimics other more common diseases such as acute appendicitis and urges laparotomy. Partial omentectomy is the therapy of choice.
