Completion of single-incision laparoscopic cholecystectomy using the modified Konyang standard method.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo 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.
methodsPatients 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.
resultsOf 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.
conclusionBased 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.
