Positive impact of mastering laparoscopic gastrectomy on shortening the learning curve of laparoscopic pancreaticoduodenectomy / 中华肝胆外科杂志

ABSTRACT

Objective:To find out whether surgeon's proficiency in laparoscopic gastrectomy helps to get over the learning curve of laparoscopic pancreaticoduodenectomy (LPD) more quickly.Methods:From January 2015 to October 2016, the clinical and perioperative data of 41 consecutive patients who underwent LPD at the Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. The learning curves were evaluated using the CUSUMOT method and RA-CUSUM method.Results:Of 41 patients, 25 were males and 16 were females, with age ranging from 25.0 to 83.0 (60.6±13.7) years. These patients all successfully underwent LPD, with operation time Mean±SD being (456.3±85.9) min. There were 4 patients (9.8%) who developed biochemical fistula and 4 patients (9.8%) grade B pancreatic fistula. There was no grade C pancreatic fistula after operation. There were 10 patients who developed postoperative complications ≥ Clavien-Dindo grade III (24.39%) and 1 died. The data of the CUSUMOT method showed the learning curve to be over after the 33rd patient and the data of the RA-CUSUM method showed the learning curve to be over after the 31st patient.Conclusions:Laparoscopic gastrectomy helped surgeons to master the key techniques in LPD faster, and to get over the learning curve more safely and quickly.
