Abstract:
Objective:To explore the learning curve of central pancreatectomy (CP) and provide an excellent reference for surgeons to get the point of this operation.Methods:Clinical data of 73 patients who underwent CP in the same operation team from January 2006 to January 2018 were collected and retrospectively analyzed by the moving average method (MAM) and the cumulative sum method (CUSUM). Data was analyzed by statistical package for social science (SPSS) software.Results:According to the MAM and CUSUM curves, the learning process of CP could be divided into two stages. At the first stage ( n=1-11), the median operation time was 340 minutes and the median intraoperative hemorrhage was 400 ml. In the second stage ( n=12-73), the median operation time was 213 minutes and the median intraoperative hemorrhage was 100 ml. The difference was statistically significant ( P<0.001). There were no significant differences between the two stages of patients in terms of other aspects ( P>0.05). Conclusions:CP can be mastered after 11 cases of exercises. In the first 11 operations, surgeons should get familiar with the operation process, respond actively to emergencies and accumulate experience to gain this surgical technique fast.
