Location is everything: The role of splenic flexure mobilization during colon resection for diverticulitis

Abstract Introduction Routine splenic flexure mobilization (SFM) has been previously recommended to ensure an adequate length for a tension free anastomosis during resection for diverticulitis. We sought to evaluate the role of selective SFM for diverticulitis, and its impact on outcomes. Materials and methods Retrospective review of elective colectomies at a tertiary care center (2007–2015) for left-sided diverticulitis were identified from the National Surgical Quality Improvement Program. Demographics and perioperative characteristics were compared; and 30-day risk-adjusted outcomes were assessed. Results We identified 208 sigmoid/left colectomy cases. A laparoscopic approach predominated (71%), and SFM was performed in 54% of cases (n = 113). Demographics and comorbidities were similar. Median operative time was greater in the SFM group [226; interquartile range (IQR): (190–267) minutes] compared to no mobilization [180; IQR: (153–209) minutes] (p
