RESUMO
Objective:To evaluate the day-surgery unit-based training of laparoscopic cholecystectomy (LC).Methods:Perioperative data of 438 patients (187 males and 251 females) with a median age of 54 (aged 17 to 91) years undergoing LC during January 2019 to April 2021 in the day-surgery unit of Chinese PLA General Hospital were retrospectively collected and subdivided according to the training methods of surgeons [Group A( n=260): conventional training vs. Group B ( n=178): protocoled stepwise training]. The protocoled stepwise training consists of the rotation in open biliary surgery unit, the stimulator-based laparoscopic training, and the stepwise procedural tutoring. The conventional training features the traditional surgical practice following senior surgeons. The technical data involving operation time, blood loss, the percentages of intraoperative decision-making by senior surgeons and the handing-over of procedure to senior surgeons, etc. were statistically analyzed. Results:The operation time was shortened in Group B [(55±30) min vs. (61±33) min], with significantly decreased percentages of intraoperative decision-making by senior surgeons [7.9% (14/178)vs. 16.9%(44/260), P<0.05] and the handing-over of procedure to senior surgeons [3.4%(6/178) vs. 11.2%(29/260), P<0.05]. Conclusion:Based on the protocoled stepwise training and the consecutive, high-volumed and standardized procedures, the laparoscopic technical proficiency and competency of the trainee surgeons have been improved.
