[Clinical application of laparoscopy-assisted total proctocolectomy using medial-to-lateral approach]

To investigate the safety and feasibility of laparoscopy-assisted total proctocolectomy using medial-to-lateral approach.

Between October 2005 and January 2012, 21 consecutive patients underwent laparoscopic-assisted total proctocolectomy by medial-to-lateral approach in Department of General Surgery in Nanfang Hospital. The clinical data and follow-up results were reviewed.

Twenty cases underwent laparoscopic resection successfully, and 1 case (4.8%) was converted to open surgery because of serious peritoneal cavity adhesion. The mean operative time was (237.1±64.2) min and intraoperative blood loss was (90.0±77.7) ml. The mean time to first flatus was (2.7±0.8) days. The mean postoperative hospital stay was (11.8±5.7) days. Three patients (14.3%) experienced postoperative complications, including anastomotic leakage (n=1), lymphatic leakage (n=1), and anastomotic stricture (n=1). The median follow-up was 22 months (4-60 months). There were two deaths including one patient died of progressive disease 5 months after surgery and the other died of multiple organ failure.

The advantages of laparoscopy-assisted total proctocolectomy using medial-to-lateral approach include simplified surgical procedure, clearly revealed surgical plane, and shortened operative time. This procedure is safe and feasible in the experienced department of laparoscopic colorectal surgery.
