The role of laparoscopic surgery in repeat ileocolic resection for Crohn's disease

Aim Laparoscopic surgery is the preferred approach for primary uncomplicated ileocolic resection (ICR); however, its role for repeat resections is unclear. This study assessed the outcomes of primary and repeated ICRs for Crohn's disease to examine rates of laparoscopy and patient morbidity. Methods A retrospective review of a prospectively maintained database was conducted at a tertiary centre between 2013 and 2019. All patients undergoing ICRs for Crohn's disease were included. The cohort was divided into three groups based on number of resections-primary (1R), secondary (2R) and tertiary or more (>2R) groups. The primary outcome was 30-day postoperative morbidity. Results Over a 6-year period, 474 patients underwent ICR for Crohn's disease, including 369 primary (1R, 77.8%) and 105 repeat (>= 2R, 22.2%) resections. A laparoscopic approach was less common in the >= 2R versus 1R groups (79.0% vs. 93.8%, P < 0.001), but rates of conversion to an open procedure were comparable. Morbidity was higher amongst repeat resections although this was not significant (20.0% vs. 14.1%, P = 0.18). Amongst cases approached laparoscopically (n = 429), rates of conversion and postoperative morbidity did not differ by stage of resection, although operative time was longer for repeat operations. Even in the group undergoing laparoscopy for tertiary or greater resections (>2R, n = 29), the rates of conversion (10%) and morbidity (14%) were relatively low. Conclusion In this contemporary series of primary and reoperative ICR for ileal CD, a laparoscopic approach is feasible and safe for the majority of repeat ICRs when performed at a high volume centre.
