Abstract
The aim of this study was to study a group of consecutive patients with enteric fistulas treated by laparoscopic surgery and to compare outcomes with a matched group of patients treated by open surgery. The outcomes of 13 patients with Crohn's disease or sigmoid diverticulitis with enteric fistulas treated laparoscopically (Group I) were compared with 13 patients matched for age, weight, gender, diagnosis, and characteristics of fistulas and treated by conventional surgery (Group II) during the same period. No patient died postoperatively in either group. Mean operative time was 183 minutes in Group I vs. 154 minutes in Group II (P = 0.280). No significant difference was found between Groups I and II in the number of patients with major postoperative complications (3 vs. 5; P = 0.462), or postoperative stay (7.6 +/- 3.6 vs. 9.2 +/- 3 days; P = 0.239). Conversion to open laparotomy occurred in one (7.7 percent) patient from Group I. No patient required readmission for secondary surgery in Group I, and two patients were readmitted and underwent reoperation for complications in Group II (P = 0.462). The laparoscopic treatment of selected cases of enteric fistulas is safe. Although most good outcome trends favor the laparoscopic group, the study is inconclusive, because no statistical difference was demonstrated with regard to operative time, number of postoperative complications, readmission rate, and length of postoperative stay, most likely because of the small number of cases in each arm of the study. Study of a greater number of cases outside the learning curve of the laparoscopic surgeons would clarify this issue. Other outcomes, including cost, pain control, cosmesis, and return to activities of daily living, need to be included in the evaluation.
