RESUMO
BACKGROUND: To date, a surgical method for single-incision laparoscopic cholecystectomy (SILC) has not been standardized. Therefore, this study aimed to introduce a standardized surgical method for SILC, in addition to reporting our experience over 10 years. METHODS: Patients who underwent SILC at a single institution between April 2010 and December 2019 were included in this study. We analyzed the patient demographics and surgical outcomes according to the surgical method used: phase 1 (Konyang standard method, KSM) comprising initial 3-channel SILC, phase 2 (modified KSM, mKSM) comprising 4-channel SILC with a snake retractor, and phase 3 (commercial mKSM, C-mKSM) using a commercial 4-channel port. RESULTS: Of 1372 patients (mean age, 51.3 years; 781 [56.9%] women), 418 (30.5%) surgeries were performed for acute cholecystitis (AC), 33 (2.4%) were converted to multiport or open cholecystectomy, and 49 (3.6%) developed postoperative complications. The mean operation time (OT) and length of postoperative hospital stay (LOS) were 51.9 min and 2.6 days, respectively. Overall, 325 patients underwent SILC with the KSM, 660 with the mKSM, and 387 with the C-mKSM. In the C-mKSM group, the number of patients with AC was the lowest (26.8% vs. 38.2% vs. 20.4%, p < 0.001) and the OT (51.7 min vs. 55.4 min vs. 46.1 min, p < 0.001), estimated blood loss (24.5 mL vs. 15.5 mL vs. 6.1 mL, p < 0.001), and LOS (2.8 days vs. 2.5 days vs. 2.3 days, p = 0.001) were significantly improved. The surgical outcomes were better in the non-AC group than in the AC group. CONCLUSION: Based on our 10 year experience, C-mKSM is a safe and feasible method of SILC in selected patients, although there were lower percentage of patients with AC compared to other groups.

Purpose: The safety of single-incision laparoscopic cholecystectomy (SILC) for acute cholecystitis (AC) has not yet been confirmed. Methods: This single-center retrospective study included patients who underwent laparoscopic cholecystectomy (LC) for AC between April 2010 and December 2020. Propensity scores were used to match patients who underwent SILC with those who underwent conventional multiport LC (CMLC) in the entire cohort and in the two subgroups. Results: A total of 1,876 patients underwent LC for AC, and 427 (22.8%) underwent SILC. In the propensity score-matched analysis of the entire cohort (404 patients in each group), the length of hospital stay (2.9 days vs. 3.5 days, p = 0.029) was shorter in the SILC group than in the CMLC group. No significant differences were observed in other surgical outcomes. In grade I AC (336 patients in each group), the SILC group showed poorer surgical outcomes than the CMLC group, regarding operation time (57.6 minutes vs. 52.4 minutes, p = 0.001) and estimated blood loss (22.9 mL vs. 13.1 mL, p = 0.006). In grade II/III AC (58 patients in each group), there were no significant differences in surgical outcomes between the two groups. Postoperative pain outcomes were also not significantly different in the two groups, regardless of severity. Conclusion: This study demonstrated that SILC had similar surgical and pain outcomes to CMLC in patients with AC; however, subgroup analysis showed that SILC was associated with poor surgical outcomes than CMLC in grade I AC. Therefore, SILC should be carefully performed in patients with AC by experienced hepatobiliary surgeons.
