title: Sigmoid volvulus in the Middle East.
abstract: Little is known about sigmoid volvulus in the Middle East despite textbooks referring to the region as part of the "volvulus belt." Our objectives were to assess the prevalence, clinical presentations, radiological findings, operative treatments, and postoperative outcomes of patients managed for sigmoid volvulus in Jordan as a model for the region. The medical records of patients with large bowel obstruction who were managed at King Abdullah University Hospital and its affiliated institutes, northern Jordan, over a 6-year period between January 2001 and January 2007 were retrospectively reviewed to identify patients with a confirmed diagnosis of sigmoid volvulus. Sigmoid volvulus was responsible for 9.2% of all cases of large bowel obstruction seen during the study period. There were 32 patients with sigmoid volvulus, 24 (75%) of whom were men. The median age of the patients was 59 years (range 21-83 years). Abdominal pain and distention were the main presentations. Colonoscopic detorsion was applied in 25 patients, which was achieved in 17 (68%) of them after the first attempt. Six patients had a gangrenous sigmoid colon, four of which required resection and a Hartmann procedure. Sigmoid resection with primary anastomosis was performed in 28 patients, including 2 with a gangrenous colon. Postoperative complications were observed in five patients, including one patient with viable colon who develop an anastomotic leak. Two patients died, making the mortality rate 6%. Sigmoid volvulus is uncommon in Jordan. Resection of the sigmoid colon with primary anastomosis appears to be the preferred procedure.
