Comparing return of bowel function after right versus extended right hemicolectomy: a retrospective analysis

Abstract

AbstractBackgroundProlonged postoperative ileus (PPOI) is associated with higher morbidity and extended inpatient stay. Although evidence suggests that PPOI is more common following right‐sided resections, it is uncertain if return to bowel function is similar following extended right (ERH) versus right hemicolectomy (RH).MethodsThe recovery of patients undergoing ERH and RH in a regional hospital in New Zealand was retrospectively compared, from 2012 to 2021. Rates of PPOI, return of bowel function and postoperative complications were compared. Other factors potentially relating to PPOI were analysed.Results293 patients were included (42 who underwent ERH, and 251 RH). PPOI was more common following ERH than RH (43% vs. 25%, P = 0.02). When accounting for the operative approach, rate of PPOI was not significantly different (42% open ERH vs. 36% open RH; P = 0.56). Excluding PPOI, return of bowel function did not differ between groups. Patient undergoing ERH versus RH had significantly higher length of stay (1 day) and Hb drop (2.5 g/L) postoperatively.ConclusionHigher rates of PPOI have been demonstrated in ERH versus RH however when controlling for approach, there was not a significant difference. Further interrogation into rates of PPOI (particularly after laparoscopic surgery) are warranted to tailor locoregional ERAS protocols.
