[Recovery and duration of work disability after laparoscopic and conventional appendectomy. A prospective randomized study]

Abstract

To evaluate whether laparoscopic appendectomy shortens the convalescence and the postoperative period until return to work when compared to conventional appendectomy, a prospective randomized trial was performed. The major endpoint of the study was the time until return to work; minor endpoints were postoperative pain, fatigue, operative time and postoperative morbidity. In all, 54 patients with a mean age of 29.5 +/- 10.1 years were randomized to open (n = 28) or laparoscopic appendectomy (n = 26). Age, sex, body mass index (BMI), American Society of Anesthesiology (ASA) rating, job status as well as histologic degree of inflammation of the appendix were comparable in the two groups. Operative time was 59.2 +/- 15.8 min for laparoscopic and 59.8 +/- 24.4 min for conventional appendectomy (P = 0.9). Some 16 laparoscopic appendectomies (62%) were performed by board-certified surgeons, while 23 conventional appendectomies (82%) were performed by residents (P = 0.003). Postoperative morbidity was comparable between the two groups. After laparoscopic appendectomy, pain was rated significantly lower on the first, second and fourth postoperative day when compared to the conventional group. There were no difference in postoperative fatigue between the groups. Time to return to work was 17.0 +/- 6.2 days in the laparoscopic group and 18.2 +/- 6.0 days in the conventional group (p = 0.5). Laparoscopic appendectomy has no advantages in terms of convalescence and time to return to work when compared to open appendectomy and should therefore be limited to selected cases.
