What the trial is, and whether it could suit you

This prospective observational study will examine how electrosurgical activation patterns during elective laparoscopic cholecystectomy are associated with surgeon experience and intraoperative difficulty. Adult patients scheduled for elective laparoscopic cholecystectomy at University Hospital of Split will receive standard clinical care; the study does not assign an intervention or change the surgical technique. A fixed camera will record only the laparoscopic monitor, and a directional microphone will record the audible signals of the electrosurgical generator. The study includes a cross-sectional comparison among surgeons with different cumulative experience and a longitudinal assessment of developing surgeons as they gain additional experience. Activation patterns will be analyzed separately during dissection of the hepatocystic triangle and separation of the gallbladder from the liv
