Transomental hernias (TOHs) are a rare finding, constituting a fraction of all intestinal hernias. Here, we report the cadaveric discovery of a spontaneous TOH involving the sigmoid colon in an 82-year-old female and discuss the relevant literature. To our knowledge, a TOH involving the sigmoid colon has not been previously reported.

Colocutaneous fistula caused by diverticulitis is relatively uncommon with colo-umbilical fistulas being even rarer. We herein report a rare case of a spontaneous colo-umbilical fistula due to diverticulitis of the sigmoid colon. The fistula developed from a diverticulum of the sigmoid colon that discharged through the umbilicus after two episodes of acute diverticulitis. The condition was succ...

Colonic endometriosis has been reported in the literature to mimic colon cancer. Patients can present with symptoms almost identical to colon cancer. We present an exemplary case of a woman who was found to have a mass on conventional colonoscopy. Virtual colonoscopy was instrumental in characterizing the obstructive sigmoid mass. A biopsy of the mass revealed sigmoid endometriosis.

A 35-year-old man was found to have a cerebral abscess secondary to a recurrent sigmoid diverticular abscess. Both cultures grew Streptococcus anginosus. Brain abscess is a rare but potential complication of sigmoid diverticulitis. Streptococcus anginosus, which is found in human gut flora, is a common cause of brain abscess.

A female patient was admitted to our hospital with sigmoid colon perforation caused by migrated biliary plastic stent, which was placed 2 months ago for the treatment of choledocholithiasis. The patient underwent sigmoid colon resection with primary anastomosis and was discharged on seventh postoperative day in good general condition.

A 68-year-old man was admitted with severe abdominal pain since the previous day. His physical examination was unremarkable, except for mild lower abdominal tenderness without rebound tenderness. Laboratory tests showed he had an elevated white blood cell count (11800 cells/μL) and increased C-reactive protein (CRP) level (105mg/L). A computed tomography (CT) scan revealed a radiodense linear f...

Two case reports of giant sigmoid diverticulum associated with diverticular disease of the sigmoid colon are presented. The clinical and radiological features of 30 similar cases found in the literature are reviewed. Our two cases represent the largest recorded diverticulum and the oldest recorded patient with this condition.

Volvulus is possible in any portion of the intestinal tract from the stomach to the sigmoid colon. Thus volvulus of the stomach, due to gastroptosis, an hour-glass contraction or certain kinds of injury, although extremely rare, is known. Volvulus of Meckel's diverticulum when it is persistent is recorded. Similarly volvulus of the small intestines, the ileo-csGcal junction or even of the csecu...
