This paper refers to 50 unusual cases of 542 consecutive adult patients who underwent surgery because of acute intestinal obstruction. Of the 38 small bowel cases, 5 were caused by hernias in anomalous recesses (1 prevesical, 2 left paraduodenal, and 2 paracecal hernias), 6 by a gallstone ileus, 14 to the presence of a bezoar or foreign body, 8 to extended postradiation perivisceritis, 3 to Meckel diverticulum volvulus, 1 to transepiploic hernia, and 1 to ileus-Meckel hematoma during anticoagulation treatment. The 12 large bowel cases included 3 diaphragmatic hernias (1 late post-trauma), 3 cases of colo-colic intussusception, 1 case of obstructive cholecystitis, and 5 cases of Ogilvie's syndrome. Major technical problems have to be immediately solved in the case of left paraduodenal, prevesical, or diaphragmatic hernias; however, during laparotomy, there may also be some difficult and unpredictable problems caused by widespread postradiation perivisceritis.

Large bowel obstruction is an important surgical emergency. The cause of obstruction may be benign or malignant, and include large bowel volvulus, polyps, intraperitoneal adhesions, strictures and neoplastic growths. Large bowel obstruction caused by gallstone(s) is a very rare phenomenon and not many cases are reported in the English literature. The present report describes a case of large bowel obstruction and faecal peritonitis caused by a gallstone perforating sigmoid colon. A database search (PubMed) did not locate any cases of large bowel perforation by a gallstone in the English literature, and hence this case report may be the first on this subject.

Laparoscopic cholecystectomy is the procedure of choice for the treatment of symptomatic biliary disease. There is currently no agreement on the management of spilled gallstones, which commonly occurs during laparoscopic cholecystectomy and may produce significant morbidity. We present a case of spilled gallstones causing cicatrical cecal volvulus and also provide a review of pertinent literature.

Gallbladder torsion or volvulus is a rare but potentially lethal entity. We report the imaging findings of gallbladder torsion and describe a potentially novel ultrasound sign for the preoperative diagnosis of torsion. An 87-year-old woman presented with a 4-day history of right upper quadrant pain. An initial right upper quadrant ultrasound exam demonstrated cholelithiasis and findings of acute cholecystitis which included gallbladder distension, wall thickening, trace pericholecystic fluid, and a positive sonographic Murphy's sign. Gallbladder torsion was prospectively diagnosed on the subsequent contrast-enhanced CT scan of the abdomen based upon the abnormal transverse orientation of the gallbladder with the neck directed laterally. Ultrasound images were reviewed and a "knot"-like hyperechoic nodular appearance of the torsed cystic duct close to the gallbladder neck was clearly apparent. Prospective identification of the torsed cystic duct may prompt the ultrasound diagnosis of gallbladder torsion.

Gastric bypass (GBP) has been the most common surgical way to treat obesity and its comorbidities. Late abdominal pain may occur by gastro-jejunal ulcers, gallstones, internal herniation or, rarely, intussusception. In an area with more than 1000 GBPs performed yearly, three patients with primary small bowel volvulus causing abdominal pain and requiring emergency or semi-urgent surgery were identified. Patients' histories, radiology, and surgery performed are presented. Weight loss followed by mesenteric narrowing of the root and thus relative elongation may make rotation of the small bowel mesentery possible. Such a torsion might be an overlooked differential diagnosis in obscure abdominal pain after GBP.

The predominant causes of acute mechanical small bowel obstruction in geriatric patients are adhesions and hernias, which is not much different than in other adult age groups. Unusual etiologies may be encountered, such as volvulus or gallstone ileus, but a displaced feeding gastrostomy tube is a distinctly rare cause of intestinal obstruction which needs to be considered by emergency physicians as it may be increasingly encountered.

Gallbladder volvulus is a rare condition with similar presentation to acute cholecystitis. It is caused by the gallbladder twisting upon its mesentery leading to potential ischemia and biliary obstruction. A 77-year-old female presented with symptoms of right upper quadrant pain and nausea. She was found to have an elevated leukocytosis and a palpable right upper quadrant abdominal mass on exam. Imaging revealed a severely distended gallbladder with pericholecystic fluid and wall thickening without gallstones. Intraoperatively, an extremely distended, ischemic gallbladder was noted to have twisted upon its mesentery. The structures were able to be identified and the gallbladder was able to be safely removed with a laparoscopic approach despite its large size. Gallbladder volvulus is important to consider in the differential of acute cholecystitis because delay in intervention could lead to gallbladder necrosis and possible perforation, increasing the patient's morbidity and mortality.
