LOWER ANTERIOR RECTAL RESECTION AND RECONSTRUCTIVE METHOD BY J-SHAPED COLON POUCH

In accordance with the wide use of stapling devices, low anterior resection for rectal cancer has been the standard operation except for a cancer that is located in extremely low in the rectum or extend to the anal verge. Low anterior resection is an excellent procedures in that the anal function is preserved completely and the technique is simple. But at the same time, if the ampulla of the rectum is resected, stool frequency occurs and impossible voluntary evacuation by abdominal pressure.In order to overcome these demerit, we make a pouch with the residual sigmoid colon by using linear stapling devices. The colon pouch plays the role of an artificial ampulla, and the patients who received these operation are able to have a voluntary stool evacuation by abdominal compression. And at the same time, the artificial ampulla can retain the stool, which decreases stool frequency. From the standpoint of quality of life, colon pouch formation is a useful surgical procedure for lower rectal cancer.
