ARTICLE HIGHLIGHTS
Research background

Postoperative pancreatic fistula (POPF) is the most formidable complication following pancreaticoduodenectomy (PD). Among the risk factors influencing the occurrence of POPF, the pancreaticojejunostomy (PJ) method stands out as a significant, modifiable factor that serves as a pivotal aspect in preventing POPF.

Research motivation

To detail the surgical procedure and technical intricacies of the novel invagination technique for PJ and assess its safety and efficacy.

Research objectives

Through the innovative optimization of PJ, reduce the incidence of postoperative complications and enhance the long-term prognosis for patients.

Research methods

This study employed a single-arm retrospective cohort study methodology to assess the effectiveness and safety of a novel invagination technique for PJ during PD.

Research results

Following application of the novel invagination technique for PJ, only three patients demonstrated grade B POPF, and no instances of grade C POPF were observed.

Research conclusions

The novel invagination procedure for PJ demonstrates safety, reliability, and significant clinical applicability, thereby qualifying as a standardized surgical approach in clinical practice.

Research perspectives

With the establishment of a standardized and homogeneous PJ method, a multicentre randomized controlled study can be conducted to further clarify its advantages, and animal experiments can subsequently be employed to elucidate the specific mechanisms and principles.
