Idiopathic segmental infarction of the greater omentum is a rare cause of acute abdomen. Patients, typically children or obese males in their fifties, present with abdominal pain located in the right upper or lower quadrant, mimicking cholecystitis and appendicitis. CT scanning and ultrasound imaging both may show a well-circumscribed soft tissue mass. Retrospective review of all patients treated for idiopathic segmental infarction of the greater omentum occurred from January 1993 to December 2001. Nine patients were treated successfully, six surgically and three medically. Conservative management of segmental infarction of the greater omentum can be proposed when correctly diagnosed by ultrasound imaging or CT scanning and the patient's condition is stable. If not, laparoscopic removal of the involved segment of the greater omentum is the treatment of choice.

Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are nonspecific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum.

The authors present case of patient with biliary stent dislocation after chest injury and fracture of VIII. rib. Polymorbid patient with cirrhosis, chronic pancreatitis, portal hypertension (Child Plugh B) and biliary stent insertion came with acute abdominal pain and inflammatory signs. Progressive signs of acute abdomen have led to laparotomy. Perforation of duodeno-jejunal-loop due to dislocated biliary stent, small loop adhesions and thickened intestine wall were found. Postsurgical period was complicated with obstructive ileus, cholecystitis and cholangiolitis and the second biliary stent was inserted. Present-day status of the patient is satisfactory.

Gallbladder perforation is an almost exclusive complication of cholecystitis, which accompanies severe inflammation of the gallbladder with or without cholelithiasis. Whether it is of a calculous or acalculous origin, gallbladder perforation, as a complication of acute cholecystitis, has common symptoms, signs, laboratory data, radiological findings and treatment modalities. Even though many reports of gallbladder perforation have been published, there are few reports of gallbladder perforation without any clinical and radiological indications. We experienced a case of a 70-year-old woman with acute abdomen, which was found to be peritonitis caused by spontaneous gallbladder perforation that was devoid of clues suggesting this condition. Although rare and unusual, this case shows that this disorder should be considered in elderly patients presenting with peritonitis with an unknown etiology.

Over a three-year period 49 cases were admitted to our hospital with an acute abdomen in pregnancy due to cholecystitis. In this article we compare surgical treatment with medical treatment and consider the aetiology of the high prevalence. Out of the 49 cases admitted, 15 cases (31%) had emergency cholecystectomy within the first week and 34 cases (69%) were treated conservatively of whom 24 relapsed many times and had to be readmitted to the hospital (mean number of admissions was 4 +/- 1.4 and the mean hospital stay was 8 +/- 2.3 days) and of the remaining 10 on conservative management, three had emergency cholecystectomy and seven reached term safely. The maternal morbidity is significantly less in the surgically treated group (P < 0.0001) but the perinatal outcome failed to show any significant difference. The frequency of acute cholecystitis in pregnancy (0.33%) is high in comparison with other studies. Although tocolytics were used in 13 cases they did not improve the fetal outcome significantly and had maternal and fetal side effects. In conclusion early surgical intervention is recommended and the use of tocolytics did not improve the perinatal outcome.

Echinococcus granulosus is one of the most important parasitic infections in the Mediterranean countries, it presents in the form of cystic lesions of the liver. During their development the cysts may cause various symptoms due to compression. Rupture of the cysts may lead to anaphylactoid reactions and/or to acute abdomen. We operated on a patient with symptoms of cholelithiasis and cholecystitis; she underwent laparoscopic cholecystectomy, during which a cystic tumour in the liver was accidentally detected. Successful laparoscopic pericystectomy was performed with Harmonic Scalpel. We are sure that laparoscopic resection of hydatid cysts is a safe option for a number of patients in the treatment of parasitic cysts of the liver.

Postoperative enteral nutrition is a widely accepted route of application for nutrition formulas due to a low complication rate, a good acceptance by patients. and a favorable cost-effectiveness. We report three cases of bezoar ileus after early postoperative enteral nutrition, using a fine needle jejunostomy (FNJ) in two cases and a nasoduodenal tube in one case. A male patient who underwent gastric resection for a gastrointestinal stroma tumor and was nourished through an fine needle jejunostomy developed an acute abdomen on the seventh postoperative day. Surgical exploration revealed a mechanical ileus caused by denaturated nutrition formula distal to the catheter tip. The second case, a female patient, underwent gastric resection for a gastric cancer and on the fourth postoperative day developed acute onset of abdominal pain. Intraoperative findings were the same as described in the first case. The third case, a male patient with necrotizing cholecystitis, underwent open cholecystectomy. Postoperative enteral feeding was performed using a nasoduodenal tube. He developed a small bowel obstruction on the 17th postoperative day that was caused by an intraluminal bezoar. In conclusion, bezoar formation represents an underestimated complication of postoperative enteral feeding. Acute onset of abdominal pain and the development of small bowel obstruction are the main clinical symptoms of this severe complication. The pathogenesis of bezoar formation remains unclear.

A 59-year-old man with myelodysplastic syndrome who was hospitalized for evaluation of fever and generalized fatigue had elevated levels of C-reactive protein and pancytopenia. A search for a site of infection and empiric treatment with antibiotics were unsuccessful. Over 5 to 6 weeks right upper quadrant pain and rebound tenderness developed. Sonographic Murphys sign was present. Computed tomography showed thickening of the gallbladder wall, and repeated ultrasonography demonstrated changes consistent with cholecystitis. Open cholecystectomy was performed as an emergency procedure. Macroscopically the resected gallbladder showed an edematous and thickened wall. Histopathologic examination revealed transmural infiltration by atypical mononuclear cells with distinct nuclei. The cells showed immunohistochemical staining for CD15, indicating myeloid lineage. By 10 days after surgery, counts of leukocytes and leukoblasts had markedly increased, reaching 36,700/microL and 76.0%, respectively. The blast crisis was thought to indicate progression from myelodysplastic syndrome to leukemia. The patient died of progressive disease 12 days after surgery. We have described a rare case of acute cholecystitis caused by infiltration of immature myeloid cells to the gallbladder. An acute abdomen complicating hematologic disorders is life-threatening and requires prompt and appropriate treatment.

Among 328 patients with dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS), 14 (4 men and 10 women, median age 44 years) had acute abdomen. DHF/DSS was initially suspected in only 2 of these 14 patients. Presumptive diagnoses of acute cholecystitis (6 acalculus and 4 calculus cholecystitis) were made in 10 patients, non-specific peritonitis in three patients, and acute appendicitis in one patients. Cholecystectomy, percutaneous transhepatic gallbladder drainage, and appendectomy were performed in three patients. Transfused blood in the three patients who underwent invasive procedures and the 11 patients who received supportive treatment included packed red blood cells (24 versus 0 units; P = 0.048), fresh frozen plasma (84 versus 0 units; P = 0.048), and platelets (192 versus 180 units; P = 0.003). Patients who underwent invasive procedures also had prolonged time in the hospital (median = 11 versus 7 days; P = 0.015). To avoid unnecessary invasive procedure-related morbidity and mortality, this report underscores the importance of a careful differential diagnosis in patients with acute abdomen in a dengue-endemic setting.

While jejunoileal diverticula are rare and often asymptomatic, they may lead to chronic non-specific or acute symptoms. The large majority of complications present with an acute abdomen similar to appendicitis, cholecystitis or colonic diverticulitis but they also may appear with atypical symptoms. As a result, diagnosis of complicated jejunoileal diverticulosis can be quite difficult, and may solely depend on the result of surgical exploration. In the absence of contra-indications, diagnostic laparoscopy has the benefit of thorough examination of the abdominal contents and helps to reach an absolute diagnosis. Surgical resection of the involved small-bowel segment with primary anastomosis is the preferred treatment in patients with symptomatic complicated jejunoileal diverticular disease. An atypical presentation of complicated jejunal diverticulitis in conjunction with sigmoid diverticulitis diagnosed with laparoscopy and treated with surgical resection is presented.
