Optimal indication of single-incision laparoscopic cholecystectomy using Konyang Standard Method in benign gallbladder diseases. JOURNAL OF MINIMALLY INVASIVE SURGERY 2022; 25:97-105. [PMID: 36177371 PMCID: PMC9494018 DOI: 10.7602/jmis.2022.25.3.97] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/09/2022] [Accepted: 08/22/2022] [Indexed: 12/12/2022]
Abstract
Purpose The optimal indications for single-incision laparoscopic cholecystectomy (SILC) have not yet been established. Methods This single-center retrospective study included consecutive patients who underwent SILC between April 2010 and June 2020. Difficult surgery (DS) (conversion to multiport or open cholecystectomy, adjacent organ injury, operation time of ≥90 minutes, or estimated blood loss of ≥100 mL) and poor postoperative outcome (PPO) (postoperative hospital stay ≥ 7 days or Clavien-Dindo grade ≥ II postoperative complications) were defined to comprehensively evaluate surgical difficulty and postoperative outcomes, respectively. Results Of 1,405 patients (mean age, 51.2 years; 802 female [57.1%]), 427 (grade I, n = 358; grade II/III, n = 69) underwent SILC for acute cholecystitis (AC), 34 (2.4%) needed conversion to multiport (n = 33) or open cholecystectomy (n = 1), 7 (0.5%) had adjacent organ injury during surgery, and 49 (3.5%) developed postoperative complications. Of the patients, 89 and 52 had DS and PPO, respectively. In the multivariate analysis, grade I AC, grade II/III AC, and body mass index of ≥30 kg/m2 were significant predictors of DS. Age of ≥70 years and DS were significant predictors of PPO. In a subgroup analysis of patients with AC, DS (9.5% vs. 27.5%, p < 0.001) and PPO (5.0% vs. 15.9%, p = 0.001) were more frequent in patients with grade II/III AC than in those with grade I AC. Conclusion SILC is not recommended in patients with grade II/III AC and should be carefully performed by experienced and well-trained surgeons.

Completion of single-incision laparoscopic cholecystectomy using the modified Konyang standard method. Surg Endosc 2021; 36:4992-5001.

Abstract
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.
