Background : Appropriately matching a surgeon with a specific level of surgical skill to a patient with a corresponding level of surgical difficulty is crucial to ensure the safety of minimally invasive distal pancreatectomy (MIDP). Difficulty scoring system (DSS) and modified difficulty scoring system (mDSS) have been developed to assess the surgical difficulty of MIDP. This study aims to develop new DSS for MIDP and compare the performance among the four systems.
Methods : Patients' clinical data who underwent MIDP for benign and malignant pancreatic lesion between March 2005 and January 2015 at Asan Medical Center were reviewed. Body mass index and tumor size are additionally included in newly developed DSS. Predictive performances of open conversion rate, long operation time, and intraoperative blood transfusion were compared between conventional and developed systems using value of area under the curve (AUC).
Results : A total of 1,053 patients were included in the study. DSS (AUC 0.80; 95%CI: 0.72-0.87) and new DSS (AUC 0.80; 95%CI: 0.72-0.88) showed the best performance to predict open conversion, but the difference was not statistically significant. All systems are not suitable for prediction of intraoperative transfusion (AUC of DSS 0.54; 95%CI: 0.49-0.59) and longer operation time over the average performance (AUC of DSS 0.57; 95%CI: 0.54-0.59).
Conclusions : DSS is suitable to predict open conversion rather than intraoperative transfusion, and long operation time. Newly developed DSS showed no additional improvement of the predictive performance.
