Laparoscopic colectomy for colon cancer: trial update.
Laparoscopic colon surgery is gaining acceptance for benign conditions, but cannot yet be considered an established procedure for malignancy. The main reported benefit of the technique is the reduction in length of hospital stay. Other potential benefits such as cosmesis, improvement in quality of life, physiologic and immunologic advantages, as well as reduced complication rates have not been clearly demonstrated. Concerns about laparoscopic colon surgery for cancer including the possibility of inadequate resection, tumor staging, and altered tumor spread due to pneumoperitoneum have only been partially addressed by retrospective and experimental studies and require a prospective randomized trial for definitive resolution. Details of the trial currently underway sponsored by the National Institutes of Health are described. Although innovations in clinical practice and increased familiarity account for the expanding popularity of laparoscopic colon surgery, results from this and similar worldwide trials are needed before this approach can be recommended for cancer.
