Total laparoscopic sigmoid and rectal surgery combined with transanal endoscopic microsurgery / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and short-term outcomes of total laparoscopic sigmoid and rectal surgery combined with transanal endoscopic microsurgery(TEM).</p><p><b>METHODS</b>The clinical data of 26 patients with colorectal carcinoma treated by total laparoscopic surgery with TEM between May 2010 and May 2011 in the Shanghai Ruijin Hospital were retrospectively analyzed.</p><p><b>RESULTS</b>All the 26 operations were successfully accomplished laparoscopically. There was no conversion to open procedure. No diverting ileostomy was made. The mean operative time was (151.6±25.9) min. The mean blood loss was (200.2±114.7) ml. The mean time to first flatus was (2.0±0.5) d. The mean tumor size was (3.0±0.7) cm and all resection margins were negative. The mean number of lymph nodes harvested was (12.9±2.2). Six patients developed postoperative anastomotic leakage, all of who had tumors in the lower rectum. There were no ureteral injury, intestinal obstruction, or pulmonary infection.</p><p><b>CONCLUSIONS</b>Total laparoscopic sigmoid and rectal surgery combined with TEM is a safe and feasible minimally invasive surgery. It is an improvement by combining laparoscopic skills with the concept of natural orifice transluminal endoscopic surgery.</p>
