AIM: To assess the feasibility and efficacy of laparoscopic total mesorectal excision (LTME) of @entity5 with preservation of anal sphincter. METHODS: From June 2001 to June 2003, 82 @entity1 with @entity5 underwent laparoscopic total mesorectal excision with preservation of anal sphincter. The lowest edge of @entity5 was below peritoneal reflection and 1.5-7 cm from the dentate line (1.5-5 cm in 48 cases, 5-7 cm in 34 cases). RESULTS: LTME with anal sphincter preservation was performed on 82 randomized @entity1 with @entity5 , and 100 % sphincter preservation rate was achieved. There were 30 @entity1 with laparoscopic low anterior resection (LLAR) at the level of the anastomosis below peritoneal reflection and 2 cm above from the dentate line; 27 @entity1 with laparoscopic ultralow anterior resection (LULAR) at the level of anastomoses 2 cm below from the dentate line; and 25 @entity1 with laparoscopic coloanal anastomoses (LCAA) at the level of the anastomoses at or below the dentate line. No defunctioning ileostomy was created in any case. The mean operating time was 120 minutes (ranged from 110-220 min), and the mean operative @entity190 was 20 mL (ranged from 5-120 mL). Bowel function was restored and diet was resumed on day 1 or 2 after operation. The mean hospital stay was 8 days (ranged from 5-14). Postoperative analgesics were used in 45 @entity1 . After surgery, 2 @entity1 had urinary retention, one had @entity834 , and another 2 @entity1 had local recurrence one year later. No interoperative complication was observed. CONCLUSION: LTME with preservation of anal sphincter is a feasible, safe and minimally invasive technique with less @entity282 and rapid recovery, and importantly, it has preserved the function of the sphincter.
