Achieving a cure for anastomotic leakage following laparoscopic low anterior resection for rectal cancer using an...

Anastomotic leakage (AL) following low anterior resection (LAR) for rectal cancer is a major complication. While most reports focus on the closure of AL using over-the-scope clip (OTSC), few reports are available on the use of through-the-scope clip (TTSC). This is because TTSC is not typically designed for full-thickness closure, unlike OTSC. However, a MANTIS clip, categorized as TTSC, is indicated for full-thickness closure. A 73-year-old man diagnosed with AL 7 days postoperatively following laparoscopic LAR underwent laparoscopic drainage and ileostomy the next day. Although the drainage led to the shrinkage of the fistula, it persisted even after 2 months. Consequently, the fistula orifice was closed using a MANTIS clip under colonoscopy and radiography. Two days later, the patient was discharged. The drain was withdrawn cautiously to prevent residual fistula and removed completely on day 29. This report highlights our experience in using a MANTIS clip for AL following LAR.
