Objectives: To determine the thickness of the gallbladder wall by ultrasound as a predictor for the conversion of laparoscopic cholecystectomy to open cholecystectomy at the Antonio Lorena Hospital in Cusco during the year 2021. Methods: The type of research is retrospective, correlational and cross-sectional, of the type of cases and controls, 126 patients who were exposed to laparoscopic cholecystectomy were studied, for the calculation of descriptive measures by control and experimental group it was by chi square OR, in case of numerical variables the t-student test, later the logistic regression models will be considered to determine the appropriate predictive model, the prediction will be compared using double-entry tables and the calculation of the specified sensitivity indicators and OR will be made considering the cut-off point or risk calculated for the thickness of the gallbladder wall, then a ROC CURVE was made to determine the best cut - off point and then determine the specificity, sensitivity, positive predictive value and negative predictive value. Results: it was found that the cut-off point for gallbladder wall thickness as a predictor for conversion is 5.31 millimeters (p<0.0001), we determined a sensitivity of 67.6%, specificity 96.1%, positive predictive value of 71.4, the predictive value negative 90.1%, and an OR 23 (p<0.0001) times more than undergoing conversion, with an area in the ROC curve of 0.901. with a cut-off point for men of 4.5mm and women of 6.04mm (<0.0001). Conclusions: The thickness of the gallbladder wall is a good predictor of conversions in cases of laparoscopic surgery, predicting 90% in men and women with a cut-off point of 5.31 mm. In the general characteristics, it is observed that males are more prone to a conversion, age is a little higher in conversion cases, there is no difference in BMI between cases and controls.
