Avoiding an overdiagnosis of pancreatic pseudocysts.

Background/aims: Thirty-six cases of pancreatic pseudocysts were retrospectively analyzed, to evaluate the clinical features of the pseudocysts which could not be differentiated from the neoplastic cysts until laparotomy.

Surgical treatment of a sigmoid volvulus associated with megacolon: report of a case.

Sigmoid volvulus occurring concomitantly with megacolon is an uncommon cause of bowel obstruction, and various approaches to treatment have been proposed. We report herein a case of sigmoid volvulus with megacolon that was successfully treated by elective surgery following endoscopic reduction during the same hospital stay. A 70-year-old woman was admitted to our hospital with abdominal pain, distension, and severe constipation.
