Title: Preoperative anthropomorphic and nutritious status and fistula risk score for predicting
clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy
Version: 1Date: 06 Mar 2020
Reviewer: Sunjong Han
Reviewer's report:
This study assesses the prognistic impact of anthropomorphic imbalance and FRS for CRPOPF
after PD. It is clear that preoperative malnutrition is strongly associated with poor outcome. In thisstudy, the authors adjusted two scores, V ATA/SATA and V ATA/SMI to subdivide anthromorphicimbalance. And they also calculated each reference value by ROC curve. It was quite interstingmethod.However, this cohort is relatively small even in a single center. And mortality and morbidity rateswere little higher than of other recent studies. Therefore, more details such as clinicopathologiccharacteristics and pathologic results, perioperative data are required to explain the outcomes ofyour center. And if possible, subgroup analysis according to existence of CRPOPF andanthropomorphic imbalances. Finally, I recommend multicenter study to generalize your theory.This is not a prospective study, so it would be possible without difficulties.
