NEW ANASTOMOTIC GUN FOR BIOFRAGMENTABLE ANASTOMOTIC RING IN LOW ANTERIOR RESECTION

PURPOSE: The biofragmentable anastomotic ring remains difficult to use for low rectal anastomosis. The authors report their experience of clinical application of the biofragmentable ring in low anterior resection with a newly designed instrument. METHODS: In this series, 31 patients underwent sphincter-preserving low anterior resections for rectal tumors from May 1993 to November 1994. With the assistance of a self-developed anastomotic instrument (biofragmentable anastomotic ring gun), biofragmentable ring anastomoses were performed following low anterior resection. RESULTS: There was no operative mortality. One patient had clinical evidence of anastomotic leakage. In postoperative follow-up, there was no anastomotic stenosis or incontinence. CONCLUSION: Therefore, we believe biofragmentable ring rectal anastomosis is a safe and reliable alternative to other anastomotic methods in rectal surgery.
