Electrosurgical Patterns and Learning Curve in Elective Laparoscopic Cholecystectomy

Sponsor: University Hospital of Split

Summary

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 liver bed. Intraoperative difficulty will be graded from the initial operative video using the Parkland Grading Scale by two independent assessors, with adjudication when needed.
