Summary

Pancreaticoduodenectomy (PD) is the only curative procedure for periampullary malignant tumors. Although modern perioperative management has greatly reduced postoperative mortality, delayed gastric emptying (DGE) remains one of the most common and troublesome complications after PD, with an incidence up to 30%. DGE leads to abdominal distension, nausea, vomiting, intolerance of oral diet, prolonged hospital stay, increased medical costs, delayed adjuvant therapy initiation, and impaired long-term nutritional recovery and quality of life.

Braun anastomosis (BE) can reconstruct the gastrointestinal tract by side-to-side jejunojejunostomy between the afferent and efferent limbs, which may reduce intestinal stasis, bile reflux and afferent limb obstruction, and theoretically lower the risk of postoperative DGE. However, current clinical studies and meta-analyses remain controversial regarding the actual efficacy of BE in preventing DGE after PD. Some studies support that BE can reduce DGE incidence, shorten hospitalization and improve postoperative recovery, while others demonstrate no statistically significant benefit, or even concern about prolonged operative time and technical difficulty. Existing evidence is limited by small sample size, retrospective design and potential selection bias, and high-quality prospective randomized controlled trials are still lacking to confirm the clinical value of BE.

This study is designed as a prospective, single-center, randomized controlled trial, aiming to evaluate the impact of routine Braun anastomosis during digestive tract reconstruction on the incidence and severity of postoperative DGE in patients undergoing pancreaticoduodenectomy for malignant tumors. The results will provide high-level clinical evidence for the rational application of Braun anastomosis in PD reconstruction and guide standardized clinical practice.
