Laparoscopic colectomy

Background: Laparoscopic colectomy has developed with the explosion of technology that has followed laparoscopic cholecystectomy. Accumulation of skills in general laparoscopic surgery has made complex surgery, such as colectomy, feasible. Methods: Three hundred fifty-nine laparoscopic cases were prospectively studied. Data has been kept on benign and malignant cases, operative results, hospital stay, and morbidity. Special care has been taken to follow malignant cases, looking for recurrence of disease. Results: There were 359 cases (206 females, 153 male) average age 58.8 years (18-94), and 149 patients had malignancy. All types of resections were performed, including 151 anterior resections, 66 right hemicolectomies (RHC), 36 total colectomies, and 22 rectopexies. Operating times fell with experience--the last 20 cases of anterior resection took 150 min (110-240) and of RHC took 130 min (65-210). Twenty-six (7%) cases were converted to open surgery. Hospital stays for anterior resection lasted 5-7 days (2-33); in the last 20 cases the average stay was 4 days. Morbidity included seven leaks (2.7%), four strictures (1.2%), 12 wound infections (3.3%), and nine ileus (2.5%). There were six deaths within 30 days--sepsis, myocardial infarction, aspiration pneumonia, and disseminated liver metastases. One hundred forty-nine cancer cases have had ten recurrences: one pelvic recurrence, six liver metastases, two para-aortic nodal, and one case of disseminated disease. Average time of recurrence was 33 months (15-46 months). Conclusions: Laparoscopy in the hands of experienced laparoscopic surgeons is a safe, efficient procedure. All types of procedures are possible. Early results in 149 malignancies are encouraging and recurrence rates are low. Prospective studies, now that skills are developed to a level comparable to that of open surgery, are now being performed to further assess laparoscopy's possible role in treating cancer.
