title: An Unusual Case of Small Bowel Volvulus.
abstract: Small bowel volvulus is a rare and life threatening surgical emergency. Nearly 75% of volvulus occurs in colon and 25% occurs in small bowel. Small bowel volvulus is abnormal twisting of bowel loops around the axis of its own mesentry leading to twisting and occlusion of mesenteric vessels causing intestinal obstruction, venous engorgement, gangrene and perforation. Small bowel volvulus is more common in neonates and young adults and very rare in adults. We are reporting a first case of small bowel volvulus and gangrene caused by herniation of ovarian cyst through mesenteric defect and twisting of small bowel around the axis of ovarian cyst leading to closed loop obstruction, small bowel volvulus and gangrene. Outcome of the disease is mainly based on the early diagnosis and intervention. Mortality is about 5.8 - 8% in nongangrenous SBV which increases drastically to 20 - 100% in gangrenous bowel.
