Sigmoid colon is one of the most variable parts of the large intestine. Here we report a very rare type of variation of the sigmoid colon. This variation was observed during the routine dissections for undergraduate medical students at Melaka Manipal Medical College (Manipal Campus) India in September 2012. In the current case, the sigmoid colon was about 60 cms long and made an inverted U shap...

    Idiopathic colon perforation is rare in children. It is more common at the extremes of age. Splenic flextures, ileocecal and lower sigmoid regions are the most common sites of perforation. Delay in proper management of this condition is associated with high mortality and morbidity rate. We report on the case of a 2.5 years old girl who presented with fever, diarrhea, nausea and vomiting and...

BACKGROUND Colon cancer can arise from the mucosa in a colonic diverticulum. Although colon diverticulum is a common disease, few cases have been previously reported on colon cancer associated with a diverticulum. We report a rare case of sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder, which presented characteristic radiographic images. CASE PRESENTATIO...

The colon involved with the sigmoid volvulus is much thicker than the normal colon. It is easy to handle and holds sutures well. Patients who have sigmoid-colon volvulus do not have much faecal loading. Most of the distension is gaseous. In the hands of experienced surgeons primary anastomosis can be done after sigmoid colectomy with safety and excellent results.

Prolapsed epiploica of the sigmoid colon through the vaginal cuff is a rare finding that has never been reported after total laparoscopic hysterectomy. We encountered a case of prolapsed epiploica of the sigmoid colon in a 40-year-old female, 4 months status after total laparoscopic hysterectomy. Diagnostic laparoscopy demonstrated prolapsed epiploica of the sigmoid colon through a dehisced vag...

Mucosa-associated lymphoid tissue (MALT) lymphoma is predominantly found in the stomach. Rarely, it is found in the proximal colon and even less so in the sigmoid colon. We present a rare case of primary sigmoid colon MALT lymphoma in a patient with concomitant Helicobacter pylori and hepatitis C infection. We also review current imaging, staging, and therapeutic modalities. To our knowledge, t...

The electric activity of the sigmoid colon (electrosigmoidogram=ESG) and rectum (electrorectogram=ERG) and their relationship was studied in nine patients. Slow waves or pacesetter potentials (PPs) of the sigmoid colon and rectum were recorded. The PP frequency and amplitude of the electrorectograms were higher (p less than 0.05) than electrosigmoidograms. Balloon distention of the sigmoid colo...

Introduction The sigmoid colon is continuous with the descending colon proximally and the rectum distally. It is an intraperitoneal organ suspended in a long mesocolon and has a median length of about 25-38 cm. It is highly mobile and quite variable in position and length [1, 2]. A longer than normal sigmoid colon is referred to as a redundant sigmoid colon or dolichosigmoid. Most of these vari...
