To determine whether the colonic epithelial proliferation rate is useful as a marker for colorectal cancer, we measured the Ki-67 labeling index (LI) in normal-appearing mucosa from the sigmoid and ascending colon in patients with two or more tumors (early cancers, which are defined as tumors the depth of invasion of which is limited to mucosal layer or submucosal layer, adenomas, or both). The...

We treated a 68-year-old woman for stenosis arising from colonic diverticulosis. Two years previously, she had developed diverticulitis of the sigmoid colon, received conservative treatment, and was being carefully watched at another hospital. She began to experience irregular bowel movements and thus visited our hospital. Detailed examination showed circumferential stenosis of the colon, and p...

When obstructive colitis becomes fulminant, it is known as 'acute necrotizing colitis'. We report a rare case of acute necrotizing colitis due to sigmoid colon cancer, in which shock status occurred within ten hours of onset. A 79-year-old female with acute abdominal pain was transported to our hospital with acute shock. Abdominal enhanced computed tomography revealed thickening of the wall of ...

background: acute obstruction of the colon continues to be a lethal disease with little improvement in the mortality rate over the past 50 years. so, this study was undertaken to define the causes of colon obstruction and their probable changes after years. â  methods: from 1979 to 2004, all records of patients with definite diagnosis of intestinal obstruction at all hospitals affiliated to shi...

BACKGROUND Typhoid fever is a severe infective disease endemic in the areas where sanitation is poor. Its serious complication is bowel perforation with terminal ileum as the commonest perforation site. We report a case of an extremely unusual site of perforation in sigmoid colon due to typhoid fever. METHODS An 18-month-old boy presented with no passage of flatus and feces along with guardin...

A 59-year-old woman presented with a history of intermittent abdominal discomfort associated with bloody bowel movements. Physical examination was notable for mild suprapubic tenderness. A colonoscopy revealed a submucosal tumor with a necrotic tip, which was nearly obstructing the colonic lumen in the sigmoid (Figure 1). An abdominal/pelvic computed tomography (CT) showed a colonic mass with a...

The ileo-sigmoid knot is a rare surgical entity, corresponding to the wrapping of ileum around base sigmoid colon forming knot.An associated condition with rapid progression intestinal gangrene and high mortality. It cause obstruction especially during pregnancy. We report here case patient at 13 weeks amenorrhea an diagnosed late stage fetal loss.

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.

Ileosigmoid knot, also known as compound volvulus, is an unusual and a rare cause of intestinal obstruction. We are reporting a case of ileosigmoid knot in a 30-year-old male, who presented with lower abdominal pain. On examination, there was tenderness in the suprapubic area and later, the patient developed features of peritonitis. Exploratory laparotomy revealed a large volume of haemorrhagic...
