Background: Volvulus commonly occurs in the sigmoid colon and caecum, but splenic flexure volvulus is rare. Features that may predispose to a volvulus include redundant colon with a narrow mesenteric attachment, non-retroperitonealized structures, and colonic dysmotility. Case Presentation: A male in his mid-20s presented with anorexia and a three-day history of colicky left sided abdominal pain. He had no previous medical history. Blood analysis was unremarkable and vital signs were normal. The patient was tender in the left upper quadrant but not peritonitic. A computed tomography scan demonstrated dilated large bowel loops with a closed loop obstruction in the left upper quadrant which was thought to originate from the transverse colon. A diagnostic laparoscopy revealed a splenic flexure volvulus with a 720-degree rotation of the bowel around its mesentery. There was a congenital absence of all splenic flexure ligamentous attachments. The bowel was severely dilated but viable. The operation was converted to a laparotomy as it was not possible to devolve the volvulus laparoscopically. A left hemi-colectomy was performed to remove the pathologically dilated and mobile portion of bowel. An isoperistaltic colo-colonic anastomosis from the mid-transverse colon to the descending colon was fashioned. The patient made a good recovery. Conclusion: Prompt management of a splenic flexure volvulus is required. Options include endoscopic detorsion, colopexy, or segmental resection due to the risk of colonic ischemia and perforation. In this case, a segmental colectomy with a primary anastomosis was performed due to the high risk of recurrence in an otherwise healthy patient.
