Comparative analysis of surgical site infection rates between transumbilical and periumbilical incisions in laparoscopic cholecystectomy: a randomized controlled trial.
Trial report in Surgical endoscopy, 2025. 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 cholecystectomy is the standard treatment for gallstone disease offering advantages such as minimal incision size and rapid recovery. The study compares the surgical site infection (SSI) rates between transumbilical (TUI) and periumbilical incisions (PUI) in this method.
methodsA randomized controlled trial was conducted from December 2021 to December 2023 at Panyananthaphikkhu Chonprathan Medical Center, Thailand. Patients undergoing laparoscopic cholecystectomy were randomly assigned to TUI or PUI groups. The primary endpoint was SSI rate, with secondary endpoints including length of hospital stay, operative time, blood loss, conversion rate, complications, cosmetic satisfaction, pain score, wound hypersensitivity, and numbness.
resultsA total of 156 patients were enrolled, with 78 patients in each group. The incidence of SSI was 14.1% in the TUI group and 10.3% in the PUI group (p = 0.46). There were no conversions to open surgery, bile leaks, intra-abdominal infections, reoperations, or mortalities observed in either group. Outcomes related to cosmetic satisfaction, wound numbness, and wound hypersensitivity were comparable between the groups. Patients who developed SSI demonstrated lower cosmetic satisfaction scores on postoperative day 7 surgery (8.47 ± 1.3) compared to those without SSI (9.5 ± 0.8) (p < 0.001), although these scores were similar by day 30. Additionally, the SSI group exhibited a higher prevalence of umbilical wound hypersensitivity on day 30 post-surgery [11 (57.9%) vs. 35 (25.7%), p = 0.04].
conclusionsSSI rates and other surgical outcomes were comparable between TUI and PUI in laparoscopic cholecystectomy, encouraging the use of either technique based on surgeon preference and patient-specific factors.
