title: [Technique and results of laparoscopic rectum resection].
abstract: The general principles of oncologic operations for colorectal cancer are the same for both open and laparoscopic surgery. Isolation of the tumor by occlusion of the intestinal lumen, early blockage of venous outflow, complete resection of the lymph node bearing mesenterium, high ligation of the artery and prevention of tumor cell dissemination during extirpation of the specimen are the most important factors. We present our technique for laparoscopic abdominoperineal resection, which fulfills the above mentioned criteria. From June 1993 to October 1994 we operated on 19 patients (median age 68 [47-91] years; male/female ratio 10/9). Laparoscopic abdominoperineal resection of the rectum was palliative in 3 patients and curative in 16. Tumors were located 3 (1-8) cm from the anal verge. In 3 patients the operation was converted to open surgery. Intraoperative complications were encountered in 3 patients. Median operation time was 300 (200-400) minutes and postoperative morbidity 8/19 (42%) leading to reoperation in one patient. 30-day mortality was nil. Three patients died 5, 8, and 14 months postoperatively due to metastatic disease (all 3 after initial palliation). One patient had local recurrence and liver metastasis and died 14 months after operation. Another patient died from liver metastases. In one patient a single liver metastasis was successfully removed. 14 patients were tumor-free after a median follow-up of 10 (3-14) months. There was no implantation metastasis on a trocar site. Laparoscopic abdominoperineal resection of the rectum is feasible and the results are comparable with those of open surgery. Local recurrence rate and incidence of liver metastases are comparable with open surgery after this short follow-up. However, 5-year survival is needed to judge the oncological radicality of laparoscopic abdominoperineal resection of the rectum.
