Risk factors for achieving textbook outcome after laparoscopic duodenum-preserving total pancreatic head resection: a retrospective cohort study

Abstract

INTRODUCTION: The risk factors for achieving textbook outcome (TO) after laparoscopic duodenum-preserving total pancreatic head resection (LDPPHR-t) are unknown, and no relevant articles have been reported so far. The aim of this study was to identify the risk factors for achieving TO after LDPPHR-t. METHODS: The risk factors for achieving TO after LDPPHR-t were retrospectively evaluated by logistic regression analysis in 31 consecutive patients from May 2020 to December 2021. RESULTS: All LDPPHR-t procedures were successfully performed without conversion. There was no death within 90 days after surgery and no readmission within 30 days after discharge. The percentage of achieving TO after LDPPHR-t was 61.3% (19/31). Among the six TO items, the postoperative complication of grade B/C postoperative pancreatic fistula (POPF) occurred most frequently with 22.6%, followed by grade B/C bile leakage with 19.4%, Clavien-Dindo≥III complications with 19.4%, and grade B/C postpancreatectomy hemorrhage with 16.1%. POPF was the major obstacle to achieve TO after LDPPHR-t. Placing an endoscopic nasobiliary drainage (ENBD) catheter and prolonged operation time (>311 min) were significantly associated with the decreased probability of achieving TO after LDPPHR-t (odd ratio (OR), 25.775; P =0.012 and OR, 16.378; P =0.020, respectively). Placing an ENBD catheter was the only significant independent risk factor for POPF after LDPPHR-t (OR, 19.580; P =0.017). Bile leakage was the independent risk factor for postpancreatectomy hemorrhage after LDPPHR-t (OR, 15.754; P =0.040). The prolonged operation time was significantly correlated with Clavien-Dindo grade≥III complications after LDPPHR-t (OR, 19.126; P =0.024). CONCLUSION: Placing the ENBD catheter was the independent risk factor for POPF and achieving TO after LDPPHR-t. In order to reduce POPF and increase the probability of achieving TO, placing an ENBD catheter should be avoided prior to LDPPHR-t.
