ABSTRACT
Objective:To evaluate the effect of multidimensional model of laparoscopic suture training in spread of laparoscopic pancreatic surgery.Methods:The surgeons who took advanced training in Department of Gastroenterology and Pancreatic Surgery in Zhejiang Provincial People’s Hospital from September 2018 to March 2020 were enrolled. Theoretical presentation, simulation training and assessment, clinical practices were included in the multidimensional training model. The " mattress suture" module (2 mattress sutures) in the LAP Mentor laparoscopic advanced simulator was used as the initial assessment and post-training assessment. The average needle loading time, time to form a knot, total time, accuracy rate of precise needle passage through the entrance and exit dots, and total aggressive tissue handing provided in the LAP Mentor were analyzed pre- and post-training. The trained surgeons were followed up for their clinical work in own hospitals.Results:A total of 13 surgeons were trained, including 4 deputy chief physicians, 7 attending physicians over 3 years, and 2 attending physicians under 3 years. The trainees had only primary laparoscopic surgery experience and no laparoscopic pancreatic surgery experience. After training in the above scheme, the average needle loading time was shortened from (93.6±31.6) s to (45.7±13.6) s, and the time to form a knot was reduced from (138.9±46.2) s to (62.1±22.9) s, and total time to accomplish the suture shortened from (15.9±3.8) min to (6.7±3.5) min. The accuracy rate of precise needle passage through the entrance and exit dots increased from (63.7±10.3)% to (89.6±9.8)%. The total aggressive tissue handing decreased from (18.2±12.5) to (6.7±4.9). All those data showed statistical differences ( P<0.05). During follow-up, all traineescan operate the laparoscopic pancreatic surgery proficiently. One trainee completed his first laparoscopic pancreaticoduodenctomy as the primary surgeon, and one trainee complete the splenic vein branch suture to stop hemostasis during laparoscopic pancreatectomy with spleen-preserving spleen, and 3 trainees completed laparoscopic pancreaticoduodenctomy as the first assistant surgeons with good outcomes. Conclusion:Multidimensional model of laparoscopic suture training can improve the trainee's suture skill and help perform complex laparoscopic pancreatic surgery with self-confidence.
