Laparoscopic resection for rectal cancer: a review.
Despite increasing evidence on the success of laparoscopic resection in colorectal diseases, clinicians remain skeptical about the application of laparoscopic resection in rectal cancer, although it may benefit patients by resulting in early return of bowel function, reduced postoperative pain, and shorter hospital stay. Rectal cancer surgery has been regarded as a technically demanding procedure. Deviation from the oncologic principle of mesrectal dissection will lead to a higher local recurrence rate. Therefore, rectal cancer was not included in earlier studies on laparoscopic versus open resection for colorectal cancer. However, many colorectal surgeons who practice laparoscopic surgery soon appreciated that the improved optics of laparoscopy can provide a much better view of the pelvis, and the Heald principle of meticulous sharp dissection for total mesorectal excision could be performed without compromise. In recent years, there has been increasing number of reports on laparoscopic resection of rectal cancers. Apart from the issues on postoperative outcomes and long-term results, laparoscopic resection has generated interest in its impact on the preservation of sexual and bladder function. We summarize the current evidence on laparoscopic resection for rectal cancer.
