Benefits and risks of using laparoscopic ultrasonography versus intraoperative cholangiography during laparoscopic cholecystectomy for gallstone disease: a systematic review and meta-analysis.
Synthesis in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundIntraoperative laparoscopic ultrasonography (LUS) or intraoperative cholangiography (IOC) can be used for visualisation of the biliary tract during laparoscopic cholecystectomy. The aim of this systematic review was to compare use of LUS with IOC.
methodsPubMed, Embase, the Cochrane Library, and Web of Science were searched (last update: April 2024). PICO: P = patients undergoing intraoperative imaging of the biliary tree during laparoscopic cholecystectomy for gallstone disease; I = intervention: LUS; C = comparison: IOC; O = outcomes: mortality, bile duct injury, retained gallstone, conversion to open cholecystectomy, procedural failure, operation time including imaging time. Included articles were critically appraised using checklists. Conclusions were based on studies without major risk of bias. Meta-analyses were performed using random effects models. Certainty of evidence was assessed according to GRADE.
resultsSixteen non-randomised studies met the PICO. Two before/after studies (594 versus 807 patients) contributed to conclusions regarding mortality (no events; very low certainty evidence), bile duct injury (1 versus 0 events; very low certainty evidence), retained gallstone (2 versus 2 events; very low certainty evidence), and conversion to open cholecystectomy (6 versus 21 events; risk ratio: 0.38 (95% confidence interval: 0.15-0.95); I
conclusionIt is uncertain whether there is any difference in mortality/bile duct injury/retained gallstone using LUS compared with IOC, but LUS may be associated with fewer conversions to open cholecystectomy and is probably associated with shorter imaging time.
