Outcome of laparoscopic colorectal resection

Background: The aim of this study was to assess the feasibility and safety of laparoscopic surgery for colorectal diseases. Methods: A retrospective review was undertaken of all patients undergoing a laparoscopic colorectal procedure (LCP) for large bowel disease. All opertions were performed by a single experienced team. Patients were divided chronologically into three consecutive groups (GI, G2, and G3). Data collection included the incidence and cause of both "proper" and "mandatory" conversions to laparotomy, the incidence and type of early and late postoperative complications, incidence of operative mortality, and the length of hospital stay. The incidences of conversion to laparotomy and of early and late postoperative complications were also determined as related to diagnosis, type of LCP attempted, and chronological group. Results: Between January 1996 and December 2001, a total of 108 patients (49 men and 59 women) with a mean age of 65.1 years underwent an LCP for colorectal disease. Proper conversion to open surgery was necessary in five patients (4.6%), whereas a mandatory conversion was needed in 10 with patients advanced cancer (9.2%). The overall morbidity rate was 11.9%. There were no anastomotic leaks. In two patients (1.85%) developed a complication requiring reoperation. Postoperative mortality was nil. Mean postoperative hospital stay was 7.2 days. The rates of conversion and of early and late complications decreased through the three chronological periods. No trocar site recurrences were observed in the cancer patients. Conclusion: Laparoscopic colorectal surgery performed in experienced centers is safe; the observed morbidity and mortality rates are low and acceptable and compare favorably to those observed after standard open surgery.
