Indications for laparoscopic colorectal surgery. Results from the Medical Centre Alkmaar, The Netherlands

Between November 1991 and May 1995, a series of laparoscopic colectomies were performed in our hospital.

Our main aim was to define more specifically the indications for laparoscopic colectomy.

A total of 69 patients underwent laparoscopic surgery for benign polypoid colorectal disease (n = 10), inflammatory bowel disease (n = 24), and colorectal malignancy (n = 35). Of the latter group, four patients underwent a palliative procedure. The conversion rate of the whole group was 29%. The main reason to convert was infiltrative growth in inflammatory disease or cancer. Respectively, seven (10%) and 12 (17%) patients sustained complications in the perioperative and early postoperative phase. Two patients died perioperatively (3%). The mean hospital stay was 12 days. On follow-up, 11 patients had developed a stenotic anastomosis, which was successfully dilated in all cases. After 3 years, the survival rate according to Kaplan-Meier is 86%, 66%, 68%, and 0% for Dukes' A, B, C, and D color carcinoma, respectively. In one patient with a Dukes B carcinoma, port site metastases were found.

Justifiable indications for laparoscopic colorectal surgery include (a) a benign polyp 20-50 cm from the anal ring; (b) mobile, inflammatory large bowel disease; (c) palliation in case of malignant disease, preferably of the left hemicolon. It remains to be proven that laparoscopic colectomy is superior and not just equivalent to open colectomy. This is especially true for resections of colorectal carcinoma with curative intent. Therefore a cost/benefit analysis should be performed in a prospective, randomized setting.
