ratory data showed a white blood cell count of 9 800 / mm 3 (normal 3 500 -9 000) with a mild left shift, a C-reactive protein level of 0.15 mg / dl (normal, < 0.17) and a creatine kinase level of 123 IU / I (normal, 62 -287). The diagnosis was sigmoid colon volvulus and the patient underwent colonoscopic decompression. He was discharged and was followed up on an outpatient basis. A similar event occurred 6 months later, and he underwent colonic decompression followed by elective laparoscopic sigmoidectomy after complete bowel preparation. The patient was placed in the lithotomy position, and a 5-mm trocar for the laparoscope was inserted through a sub-umbilical incision, while the other three 5-mm trocars were inserted in the right upper, right lower, and left upper quadrants along the mid-clavicular line, respectively, and CO 2 gas was then insuffl ated at pressure of 8 mmHg. An elongated sigmoid colon with moderate dilatation was seen, with a long narrow-based mesentery and close approximation of the two limbs of the sigmoid loop. After simple fenestration of the sigmoid mesentery, a balloon catheter was introduced into the sigmoid colon through the anus, and the sigmoid colon was then tied tightly with umbilical tape just below the insuffl ated balloon. The catheter was carefully pulled out, creating a rectosigmoid prolapse ( • ▶ Fig . 2a,b ). The colon was transected at the rectosigmoid junction, the divided sigmoid colon was exteriorized via the anus, and the redundant part was resected with dissection of the arcade and straight vessels ( • ▶ Fig . 2c ).
