A Study of the Comparison Between Preoperative Ultrasonography Findings With Intraoperative Observations in Laparoscopic Cholecystectomy.

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
aimThis study aims to evaluate the accuracy of ultrasonography (US) by comparing preoperative ultrasonographic findings with intraoperative observations during laparoscopic cholecystectomy (LC). MATERIALS AND
methodsAn observational analytical study was conducted at a tertiary hospital in Pune over two years and included 98 patients aged 20-80 with symptomatic cholelithiasis confirmed by US. Preoperative parameters assessed included gallstone number, gallbladder volume, wall thickness, and pericholecystic fluid. These were compared to intraoperative findings during LC. Data were analyzed using SPSS Statistics for Windows, Version 16 (Released 2007; SPSS Inc., Chicago, Ill), with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) calculated for the US parameters.
resultsThe mean patient age was 44.14±15.06 years, with a female predominance (70%). US showed high sensitivity (78.13%) but low specificity (35.29%) for detecting the number of stones, and showed high specificity (100%) but low sensitivity (21%) in the assessment of gallbladder wall thickness. For detecting gallbladder distension, US had a sensitivity of 69.7% and a specificity of 11.1%, while it achieved perfect sensitivity and NPV (100%) for evaluation of pericholecystic fluid.
conclusionsPreoperative US provides valuable insights for surgical planning, with high sensitivity and specificity for gallbladder wall thickness and pericholecystic fluid. However, its accuracy in detecting the number of stones and gallbladder distension is moderate. US can be considered a useful investigation for diagnosing cholelithiasis. It may be used to predict the fate of LC, but further studies need to be carried out to confirm its surgical importance.
