Comparative study of monopolar electrocautery versus ultrasonic dissection of gallbladder in laparoscopic cholecystectomy

This study is a prospective observational study evaluating the effectiveness and safety between surgeries performed using electrocautery and those performed using the curved jaw cordless ultrasonic dissector during laparoscopic cholecystectomy. Patient will be selected through consecutive sampling as they present for surgery and meet inclusion criteria. The choice of instrument will be based on availability and surgeon preference without any predefined allocation. The primary outcome measures include: operative time, intraoperative blood loss, gallbladder perforation rate, postoperative pain scores, postoperative complications. Data will be statistically analysed using appropriate tests, and the results will help determine whether the curved jaw cordless ultrasonic dissector offers significant clinical advantages over traditional electrocautery in terms of effectiveness, safety and patient outcomes.
