Abstract

Abstract Purpose Laparoscopic colectomy for transverse colon cancer (TCC) can be technically demanding due to the anatomical complexity of the region. In Japan, the Endoscopic Surgical Skill Qualification System (ESSQS) was established to improve the skill of laparoscopic surgeons and further develop surgical teams. We examined the safety and feasibility of laparoscopic colectomy for TCC, and evaluated the effects of the Japanese ESSQS in facilitating this approach. Methods We retrospectively reviewed 136 patients who underwent laparoscopic colectomy for TCC between April 2016 and December 2021. Patients were divided into an expert group (surgery performed by an ESSQS-qualified surgeon, n = 52) and a non-expert group (surgery performed by an ESSQS-unqualified surgeon, n = 84). Clinicopathological and surgical features were compared between groups. Results Postoperative complications occurred in 37 patients (27.2%). The proportion of patients who developed postoperative complications was lower in the expert group (8.0%) than in the non-expert group (34.5%; p < 0.017). Multivariate analysis revealed “Operation by ESSQS-qualified surgeon” (Odds ratio [OR] 0.360, 95% confidence interval [CI] 0.140–0.924; p = 0.033), blood loss (OR 4.146, 95%CI 1.688–10.184; p = 0.002) and clinical N status (OR 4.563, 95%CI 1.814–11.474; p = 0.001) as factors independently associated with postoperative complications. Conclusion The present multicenter study confirmed the feasibility and safety of laparoscopic colectomy for TCC and revealed that ESSQS-qualified surgeons achieved better surgical outcomes.
