Laparoscopic surgery for colorectal cancer.
Despite the widespread use of laparoscopic techniques in many fields, in the realm of malignant diseases, a great concern has been raised regarding safety, efficacy, and long-term results. The authors report their experience of 163 patients operated on for colorectal malignancies by minimally invasive access. The conversion rate (20.4%), morbidity (15.1%), and null mortality compare well with other studies published worldwide. The postoperative outcome was characterized by a prompt return to activity (1.3 days) and of bowel movements (2.9 days), while length of stay and an adequate oral resumption were comparable to those of open surgery. Peritoneal lavage did not show tumor cells disseminated during the operative maneuvers. The distance of tumor from resection margins and the number of lymph nodes harvested with the operative specimen did not vary from those obtained in open surgery. Two patients (1.2%) recurred at the mini-laparotomy and port sites, but, in both cases, the traumatic manipulation of the cancer specimen was probably responsible for the event. After a mean follow-up of over 3 years, 34 patients died of neoplastic recurrence, and 17 are alive with disease relapse. The laparoscopic approach to colectomy has not yet gained an unquestioned place in the experience of the colorectal surgeon. However, if sound surgical method and judgement are used to minimize local recurrences, and if a better preservation of postoperative immune function proves to be of clinical significance in the long term, laparoscopic colectomy may prove to be a safe and less stressful approach to colon resection.
