Clipless hand-assisted laparoscopic total colectomy using Ligasure Atlas.

Hand-assisted laparoscopic total colectomy for ulcerative colitis has allowed less invasive operations in acute severe colitis and poor risk, and has not yet been widely applied for the reason of prolong the operating time in comparison with open surgery. We present the advantages of the use of the LigaSure Atlas vessel sealing for vascular control during laparoscopic surgery. A retrospective study was conducted to compare 15 patients who underwent hand-assisted laparoscopic total colectomy using an ultrasonic coagulator from January 1988 to September 2002 (US group) with 18 patients who were operated using LigaSure Atlas (LS group) from October 2002 to December 2003. There was no significant difference in the background factors of patients between both groups. The operating time was 225 +/- 58 min in the LS group and less than 280 +/- 105 min in the US group. Intraoperative blood loss was 91 +/- 22 ml in the LS group and less than 212 +/- 178 ml in the US group. Postoperative bleeding did not occur in the LS group, but occurred in 1 patient in the US group (6.6%) and this patient required re-operation. Postoperative seroma formation in the abdomen was found in 3 patients of the US group (20%). The procedure using LigaSure Atlas reduced the operating time, intraoperative bleeding and operator's stress in comparison with standard ultrasonic coagulation.

Graciloplasty for internal and external sphincteric resection of lower rectal cancer.

Anal sphincteric resection for rectal cancer is most commonly followed by colostomy in the lower abdominal wall, which enforces quite a poor quality of life due to a permanent stoma. For surgeons treating lower rectal cancer, the goal is to achieve defecation via the anus without placing a stoma. Internal sphincteric resection, partial external sphincteric resection and coloanal anastomosis have been reported for the treatment of lower rectal cancer with avoiding a colostoma. Extended resection of the external sphincter, however, limits patient's daily activities because of poor functional results and necessitates reconstruction of damaged anal function. This paper describes a case of graciloplasty for postoperative anal dysfunction that yielded a good clinical outcome in a 65-year-old female who had undergone very low anterior resection with complete internal and partial external sphincteric resection for lower rectal cancer.
