Abstract
A 75-year-old man presented with a type-2 tumor mass measuring 30 mm located anterior to the right side of the rectum (Rb). The mass was diagnosed as a rectal cancer (cMP, cN0, cH0, cP0, cM0, cStage I) and treated by a laparoscopic low anterior resection using a prolapsing technique. On postoperative day 14, the patient developed a fever, pollakiuria, and testicular pain. Although conservative medical treatment provided temporary relief, the symptoms recurred. On postoperative day 36, abdominal computed tomography (CT) and water-soluble contrast enema results suggested a diagnosis of a seminal vesicle-rectal fistula. On postoperative day 42, an ileostomy was performed. The ileostomy was closed 10 months after the surgery, and there has been no recurrence of the seminal vesicle-rectal fistula to date. There have been few reports of seminal vesicle-rectal fistulas reported as postoperative complications of rectal cancer. Here we reported such a case and discuss the literature.
