1 · What the graph read from it

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.

2 · The registry

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

purposeThe Tokyo Guidelines 2018 introduced the Surgical Difficulty Score (TGDS18) to assess laparoscopic cholecystectomy (LC) difficulty based on intraoperative findings. This study aimed to predict surgical difficulty preoperatively using clinical factors correlated with TGDS18.

methodsOf 369 LC cases for cholecystitis (Jan 2014-Jul 2024), 106 with operative video data were analyzed. Multivariate analysis of 69 with preoperative CT (≤14 days) evaluated the association between preoperative clinical findings and TGDS18 sub-scores (around the gallbladder, Calot's triangle, gallbladder bed, additional findings, unrelated to inflammation).

resultsTGDS18 was positively correlated with operative time, blood loss, and hospital stay (all p < .001). Patients undergoing subtotal cholecystectomy had higher TGDS18 scores (median 20, p < .001). Six preoperative findings strongly associated with TGDS18 sub-scores were identified: calcified stone in cystic duct, TG18 Grade ≥2, preoperative gallbladder drainage, urgent operation, pericholecystic inflammation, and age-adjusted Charlson comorbidity index ≥7. The rate of subtotal cholecystectomy increased with the number of findings linked to the "Calot's triangle" sub-score-cystic duct stone and TG18 Grade ≥2. (0% with no findings, 8% with one finding, and 23% with both, p = .009). Similarly, the risk of cholecystectomy requiring the posterior wall left can be predicted by the number of clinical findings related to the 'Gallbladder bed' sub-score (p = .009).

conclusionsThe clinical findings linked to TGDS18 allow tailored preoperative strategies for acute cholecystitis.
