Laparoscopic open surgery in ileostomy reversal in Crohn's disease: A retrospective study.

Background: Although minimally invasive surgery is becoming more commonly applied for ileostomy reversal (IR), there have been relatively few studies of IR for patients with Crohn's disease (CD). It is therefore important to evaluate the potential benefits and risks of laparoscopy for patients with CD.

Aim: To compare the safety, feasibility, and short-term and long-term outcomes of laparoscopic IR (LIR) open IR (OIR) for the treatment of CD.

Methods: The baseline characteristics, operative data, and short-term (30-d) and long-term outcomes of patients with CD who underwent LIR and OIR at our institution between January 2017 and January 2020 were retrieved from an electronic database and retrospectively reviewed.

Results: Of the 60 patients enrolled in this study, LIR was performed for 48 and OIR for 12. There were no statistically significant differences in baseline characteristics, operation time, intraoperative blood loss, days to flatus and soft diet, postoperative complications, hospitalization time, readmission rate within 30 d, length of hospitalization, hospitalization costs, or reoperation rate after IR between the two groups. However, patients in the LIR group more frequently required lysis of adhesions as compared to those in the OIR group (87.5% 41.7%, respectively, < 0.05). Notably, following exclusion of patients who underwent enterectomy plus IR, OIR was more advantageous in terms of postoperative recovery of gastrointestinal function and hospitalization costs.

Conclusion: The safety and feasibility of LIR for the treatment of CD are comparable to those of OIR with no increase in intraoperative or postoperative complications.
