In those clinical settings where surgical expertise and equipment are available and affordable, diagnostic laparoscopy and LA (either in combination or separately) seem to have various advantages over OA. Some of the clinical effects of LA, however, are small and of limited clinical relevance. In spite of the mediocre quality of the available research data, we would generally recommend to use laparoscopy and LA in patients with suspected appendicitis unless laparoscopy itself is contraindicated or not feasible. Especially young female, obese, and employed patients seem to benefit from LA.
Laparoscopic versus open appendectomy: a prospective randomized trial.
To study comparative results between laparoscopic and open appendectomy, all the patients with suspected acute appendicitis who presented between January 1992 and December 1994 (N = 210) were randomized into two groups: laparoscopic (LA, n = 106) and open appendectomy (OA, n = 104). Patient demographics, pathological findings, operative time, postoperative course, and cost were analyzed. Age, gender, previous laparotomy, intraoperative diagnosis, and perforated appendix rate were comparable between both groups. Mean operative time was longer in the LA group (p < 0.05). Earlier resumption of a regular diet, shorter postoperative stay, and less postoperative analgesia also were observed in the LA group (p < 0.05). Postoperative morbidity and hospital readmissions were similar in both groups (p > 0.05). Higher operative cost was observed in the LA group, but global cost was lower in this group (p < 0.05). Laparoscopic appendectomy shows a more comfortable postoperative course (oral resumption, postoperative stay, and analgesia) over open appendectomy, with similar postoperative morbidity. The LA group showed more operative but less global cost.
