Abstract
As laparoscopy becomes a greater part of a general surgeon's practice, each new application must be analyzed. The purpose of this article is to report a four-year experience with laparoscopic appendectomy, with special attention to complications. All patients undergoing appendectomy by members of the General Surgery Department of Columbia Hospital between December 20, 1990, and December 24, 1994, were included (n = 434). Medical records were reviewed, and data were analyzed using multiple regression analysis, analysis of variance, and Pearson's chi-squared test. The number of post-operative intra-abdominal abscesses following laparoscopic appendectomy tended to be higher; however, this did not reach statistical significance. Conversely, all other complications combined demonstrated a rate of 4.3 percent for laparoscopic procedures and a rate of 8.5 percent for open procedures. Again this tended toward, but did not reach, statistical significance. Advantage in length of stay was approximately two days, with a mean length of stay for patients undergoing laparoscopic appendectomy of 3.3 days, whereas that for open appendectomy was 5.7 days. Laparoscopic appendectomy has significant advantages in terms of patient comfort and length of stay, and its overall complication rate seems to be lower than with open procedures; however, its rate of intra-abdominal abscess may actually be higher. Further study is recommended.
