Primary duct closure after laparoscopic common bile duct exploration in elderly patients with cholecystocholedocholithiasis: a propensity-matched analysis.
Article in BMC surgery, 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
backgroundLaparoscopic common bile duct exploration (LCBDE) is a minimally invasive option for treating cholecystocholedocholithiasis. Primary duct closure (PDC) after laparoscopic common bile duct exploration has been shown to be safe. This study aims to evaluate the feasibility and safety of LCBDE + PDC in elderly (≥ 65 years) patients.
methodsThis study included 284 elderly patients who underwent LCBDE(PDC group = 86, T-tube drainage group = 198). We compared the baseline characteristics and perioperative data between the two groups. The Propensity Score Matching (PSM) method was employed to balance the baseline characteristics of the groups and mitigate potential biases.
resultsThe PDC group showed shorter operative time (105 vs. 130 min, P < 0.001), reduced postoperative hospital stays (7 days vs. 8 days, P < 0.001) and total hospital stays (11.5 days vs. 13 days, P < 0.001), and lower costs (3273.6 USD vs. 3848.4 USD, P < 0.001) compared to the T-tube group. The rates of postoperative bile leakage (4.65% vs. 2.02%, P = 0.25) and severe complications (3.49% vs. 3.54%, P = 1) were comparable between the two groups. After PSM, PDC group maintained advantages in operative time (105 min vs. 130 min, P < 0.001) and costs ( 3310.9 USD vs. 3719.4 USD, P = 0.012).
conclusionsOur study demonstrates that LCBDE + PDC is a safe and feasible treatment for elderly patients with cholecystocholedocholithiasis.
