Impact of institutional volume on short‐ and long‐term outcomes after laparoscopic colectomy

Abstract

AbstractIntroductionThe impact of institutional volume on postoperative outcomes after laparoscopic colectomy is still being debated. This study aimed to investigate whether differences in postoperative outcomes of laparoscopic colon resection exist between high‐ and low‐volume centers.MethodsData were reviewed for 1360 patients who underwent laparoscopic colectomy for colon cancer between 2016 and 2022. Patients were divided according to whether they were treated at a high‐volume center (≥100 colorectal surgeries annually; n = 947) or a low‐volume center (<100 colorectal surgeries annually; n = 413). Propensity score matching was applied to balance covariates and minimize selection biases that could affect outcomes. Finally, 406 patients from each group were matched.ResultsAfter matching, patients from high‐volume centers showed a higher number of retrieved lymph nodes (19 vs. 17, p < .001) and more frequent involvement of expert surgeons (98.3% vs. 88.4%, p < .001). Postoperative complication rates were similar between groups (p = .488). No significant differences between high‐ and low‐volume centers were seen in relapse‐free survival (88.8% each, p = .716) or overall survival (85.7% vs. 82.8%, p = .480).ConclusionThe present study suggests that in appropriately educated organizations, relatively safe procedures and good prognosis may be obtained for laparoscopic colectomy cases, regardless of institutional volume.
