Purpose: Laparoscopic left lateral sectionectomy (LLLS) is a feasible and safe procedure with a relatively smooth learning curve. However, single-incision LLLS requires extensive surgical experience and advanced techniques. The aim of this study is to report the standardized single-incision plus one-port LLLS (reduced port LLLS, RPLLLS) technique and evaluate its safety, feasibility, and effectiveness for junior surgeons. Methods: Between January 2008 and November 2020, the clinical records of 49 patients who underwent LLLS, divided into the conventional LLLS (n = 37) and the RPLLLS group (n = 12), were retrospectively reviewed. The patient characteristics, pathologic results, and operative outcomes were evaluated. Results: A history of previous abdominal surgery in the RPLLLS group was significantly high (56.8% vs. 91.7%, p = 0.552). Notably, junior surgeons performed 62.2% of the conventional LLLSs and 58.4% of the standardized RPLLLSs. There were no significant differences between the two groups in terms of median operative time (121.0 vs. 113.5, p = 0.387), median blood loss (13.0 vs. 8.5, p = 0.518), median length of hospital stays (7.0 vs. 7.0, p = 0.408), and morbidity rate (2.7% vs. 0%, p = 0.565), respectively. Conclusion: This standardized RPLLLS is a feasible and safe alternative to conventional LLLS and may become the ideal training procedure for both junior surgeons and surgeons aiming to learn more complex procedures.
