Totally Laparoscopic Ileocolic Resection for Complex Enterovisceral Fistulas in Crohn's Disease: A Comparative Study.

Introduction: In primary Crohn's disease (CD), laparoscopic ileocolic resection has been shown to be both feasible and safe, and is associated with improved outcomes in terms of postoperative morbidity and length of hospital stay. However, it is unclear whether the laparoscopic approach can be routinely proposed as a safe procedure for patients with complex enterovisceral fistulas.The aim of this study is to assess the feasibility and safety of laparoscopic surgery for complex enterovisceral fistulas, and compare it with CD patients who underwent primary laparoscopic ileocolic resection.
Patients and Methods: All patients who underwent laparoscopic primary ileocolic resection (LICR) for complex enterovisceral fistulas between July 2006 and July 2017 were included. They were compared with all consecutive patients who underwent LICR for nonfistulizing CD in the same period of time. Patients with previous bowel resections or recurrent disease were excluded.
Results: Nineteen patients with 20 enterovisceral fistulas (group I) were compared with 61 patients who underwent LICR for nonfistulizing disease (group II). There were no differences between the groups in age, sex, preoperative body mass index, nutritional status, and American Society of Anesthesiology score. There was no conversion to open surgery in both groups.There were no significant differences between groups in terms of operative time [120 (range: 65 to 232) vs. 117 (range: 62 to 217) min, P=0.7], hospital stay [6 (5 to 8) vs. 7 (5 to 65) days, P=0.56], overall morbidity 26.3% versus 16.4% (P=0.33), major morbidity (Clavien-Dindo >3) 15.7% versus 10% (P=0.66) and reoperation rates 5.3% versus 4.9% (P=0.9). There was no mortality in both groups.
Conclusions: Our experience shows that the laparoscopic approach for complex enterovisceral fistulas in selected CD patients is both feasible and safe in the hands of experienced inflammatory bowel disease surgeons with extensive expertise in laparoscopic surgery. Larger study cohorts are needed to confirm these findings.
