Purpose: Laparoscopic surgery for complicated Crohn's (CD) is often technically challenging. Previous studies are limited by the comparison of heterogeneous cohorts of patients undergoing laparoscopic vs open surgery. We aimed to compare perioperative and long-term outcomes of matched patients undergoing laparoscopic and open colonic and ileocolonic resection. Primary outcomes were operative time, blood loss, and complications. Long-term outcomes were subsequent intraabdominal CD surgery, incisional hernia repair, and stoma reversal rates.
Methods: Laparoscopic and open CD patients were 1:1 propensity score matched on age, body mass index, sex, indication, ASA grade, prior abdominal surgery, and postoperative Crohn's medication use based on the laparoscopic approach.
Results: A total of 906 patients underwent surgery for complex CD. After propensity matching, 386 were analyzed (193 open/193 lap, 51.3% male, mean age 33.9 + / - 12.6). Mean follow-up was 9.8 (range 7.9-12.1) years. Length of stay [(LOS) 6 (4, 8) vs 8 (5, 11) days, p < 0.001] and operative time [154 (110, 216) vs 176 (126, 239) min, p = 0.03] were shorter in the laparoscopic group. There was no difference in other complications or mortality. After adjusting for postoperative medications, no association was found between operative approach and subsequent intra-abdominal operation or incisional hernia repair. Laparoscopic patients were less likely to have postoperative sepsis [OR 0.40 (0.18, 0.91), p = 0.03].
Conclusion: In the setting of complicated Crohn's, in matched cohorts, laparoscopic surgery is associated with reduced operative times and LOS. Mortality, reoperation, and symptomatic hernia rates were equivalent to open surgery. Patients undergoing laparoscopic surgery are less likely to experience postoperative sepsis.
