    Abstract:
    INTRODUCTION: In laparoscopic rectal surgery, there are some limitations on a surgeon's ability to maneuver, especially in transection of the lower rectum. To achieve minimally invasive surgery, safe anastomosis, including proper rectal transaction, is necessary. METHODS: To overcome the difficulty in lower rectal resection, we followed a series of steps. First, we completely mobilized the rectum to the pelvic bottom, just above the anal canal, making the lower rectum mobile and allowing for an easy rectal transection. To secure the transaction, the mesorectum around the transection must be properly divided. We recommend placing the lower right quadrant port as caudal as possible to properly staple the rectum. We found a 60 mm compression-type stapler most suitable for rectal transection. To wash and flatten the rectum, a detachable intestinal clip is quite useful because of its flexibility. Finally, in addition to conventional abdominal drains around the anastomotic site, we employed transanal tube to actively decompress rectal pressure inside the anastomotic site. RESULTS: Between August 2009 and July 2010, 101 patients underwent laparoscopic low anterior resection using this technique. Most patients, 98.0% (99/101), underwent lower rectum transection using a single-fire cartridge. The anastomotic leakage rate was only 1.0% (1/101) in total and 1.3% (1/78), when not including patients with diverting stoma. CONCLUSION: We have to follow up with more patients to conclude whether our technique is effective in the long term. However, this step-by-step technique could lead to safe anastomosis in laparoscopic low anterior resection for rectal cancer.
