Although SV commonly occurs due to predisposing factors like anatomic variations, age-related motility disorders, chronic constipation, and neurologic diseases, its incidence following sigmoid colon cancer surgery has rarely been reported.

Sixteen months postoperatively, he developed an incisional hernia at the umbilical site, which was treated with a laparoscopic repair using an intraperitoneal onlay mesh. After the hernia surgery, the patient had no anastomotic leakage or stenosis on regular follow-ups. However, 65 months after the first surgery, he presented with abdominal pain and distension. A computed tomography revealed that the remnant sigmoid colon was distended in a twisting manner around the anastomosis, leading to the diagnosis of SV.

The procedure involved resection of the sigmoid colon including the prior anastomosis with a left pararectal incision and DST re-anastomosis using a 25-mm circular stapler.
