Robot‐assisted duodenum‐preserving pancreatic head resection with pancreaticogastrostomy for benign or premalignant pancreatic head lesions: a single‐centre experience

Abstract

BACKGROUND: The purpose of this study was to compare short- and long-term outcomes of modified robot-assisted duodenum-preserving pancreatic head resection (RA-DPPHR) versus robot-assisted pancreaticoduodenectomy (RA-PD). METHODS: Matched for age, sex, ASA classification, tumour size, history of abdominal surgery and pathological type, 34 patients undergoing RA-DPPHR and 34 patients undergoing RA-PD between January 2010 and December 2016 were retrospectively analyzed. RESULTS: The RA-DPPHR group had shorter surgical time (188.2 vs. 386.3 min, p < 0.001) and less blood loss (168.2 vs. 386.3 ml, p = 0.026) but higher complication rate (47.1% vs. 32.4%, p = 0.105) and pancreatic fistula rate (32.4% vs. 17.6%, p = 0.161). Hospital mortality was 2.9%. Exocrine insufficiency was lower in the RA-DPPHR group (3.0% vs. 24.2%, p = 0.027). Endocrine insufficiency was observed in one RA-DPPHR patient and 5 RA-PD patients (p = 0.197). CONCLUSIONS: Modified RA-DPPHR benefits in terms of better conservation of exocrine and endocrine pancreatic functions at the expense of a significant morbidity and non-zero mortality.
