Laparoscopic-assisted colectomy. Initial experience.

Objective: The authors studied the results of laparoscopic colectomies performed by a surgical team on 80 consecutive patients and compared these results with standard open colectomies.

Methods: Eight consecutive laparoscopic-assisted colectomies were performed by Norfolk Surgical Group in a 14-month period and compared to 53 patients who had a conventional open colectomies. Analysis included indications for surgery, types of procedure, complications, incidence and causes for conversion, length of procedure, duration of postoperative ileus, hospital stay, operating room and total hospital charges, and examination of the pathologic specimens.

Results: Many different types of colectomies were performed successfully and safely for a variety of surgical indications. The conversion rate was 22.5%, which decreased to 15% in the second half of the series. Complications in patients who underwent laparoscopic operations were not severe in number of type. The length of the operative procedure, operating room charge, and the total hospital charge were greater for patients undergoing laparoscopic-assisted colectomies. Patients who underwent laparoscopic operations had a shorter period of postoperative ileus and less pain, resumed a regular diet sooner, and were discharged from the hospital sooner than patients who underwent open colectomies. There was no significant difference in the pathology specimens obtained by laparoscopic-assisted colectomies compared with conventional open colectomies for length of specimen, surgical margins, and number of lymph nodes retrieved.

Conclusions: This study indicated that laparoscopic techniques can be applied safely and effectively to a broad range of colonic operations. Laparoscopic-assisted colectomies take longer to perform and are more costly, but are associated with less paralytic ileus, less pain, and reduced hospital stay. Laparoscopic colectomies for the treatment of malignancy are achievable technically, but will require careful long-term study.
