Safety and feasibility of robotic single-port (SP) cholecystectomy compared to conventional laparoscopic cholecystectomy: a propensity score matching analysis.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAdvancements in robotic systems have expanded the scope of minimally invasive hepatobiliary surgery. Specifically, the single-port (SP) robotic system offers distinct advantages for single-incision cholecystectomy. This study aimed to evaluate perioperative outcomes between SP robotic cholecystectomy (SP RC) and conventional laparoscopic cholecystectomy (LC).
methodsThis retrospective, single-center study included patients who underwent LC or SP RC between November 2020 and April 2023. Propensity score matching (PSM) was performed using covariates including age, sex, body mass index, American Society of Anesthesiologists score, GB stone, GB polyp, acute cholecystitis, DM, HTN, the number of cases of preoperative ERCP, and the surgeon. Of the 1184 enrolled patients, 340 pairs were successfully analyzed after PSM. Perioperative outcomes, including operative time, pain scores, length of stay, and postoperative complications, were compared between the matched groups.
resultsAfter PSM, BMI was comparable between the LC and SP RC (24.6 vs. 25.2 kg/m2, P = 0.824). The operative time was significantly shorter in the SP RC group (45.0 vs. 40.0 min, P < 0.001). There were no significant differences in postoperative pain scores (3 vs. 3 scores, P = 0.247) or incidence of symptomatic incisional hernia (4 vs. 6 cases, P = 0.754).
conclusionsSP RC demonstrated comparable safety and feasibility to conventional LC. Further prospective studies are needed to assess its broader clinical applicability.
