Abstract
The advantages of laparoscopy in the treatment of benign diseases have been well demonstrated. Compared with laparotomy, the laparoscopic approach is associated with a shorter hospitalization period, shorter duration of ileus, decreased postoperative pain, earlier return to work, and improved cosmesis. The role of laparoscopy for the treatment of gastrointestinal malignancy has had a slower evolution and been the subject of considerable debate over the past decade. Since 1991, several concerns have limited the widespread use of laparoscopy for attempted cure of colorectal carcinoma. This review aims to analyze the results of several studies published to date on short and long term outcome of laparoscopy for colorectal carcinoma, based on levels of evidence. From the least to the most convincing data, the hierarchy of study designs progresses through a spectrum ranging from retrospective reviews to prospective series, to case-controlled, cohort, and ultimately randomized controlled trials.
