Drain selection reduces pancreatic fistulae risk: a propensity-score matched study

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Postoperative Care

Background:

• Effective drainage management is critical for minimizing complications after pancreaticoduodenectomy (PD).
• Postoperative complications can significantly impact patient recovery and outcomes.
• Evaluating different drainage systems is essential for optimizing surgical care.

Purpose of the Study:

• To compare the incidence of postoperative complications between closed and open drainage systems following PD.
• To assess the efficacy of closed drainage in preventing retrograde infections and pancreatic fistulas.

Main Methods:

• A prospective study involving 100 patients undergoing PD, divided into open and closed drainage groups.
• Propensity score matching (PSM) was used to control for potential confounding variables.
• Postoperative complications were meticulously recorded and compared between the matched groups.

Main Results:

• The closed drainage group showed significantly lower rates of pancreatic fistulae requiring treatment (11.5% vs. 46.2% in the open group post-PSM).
• Wound infections and intra-abdominal abscesses were exclusively observed in the open drainage group.
• Exogenous infections, identified through drainage fluid culture, were present in the open group but absent in the closed group.

Conclusions:

• Closed drainage systems are effective in preventing postoperative retrograde infections after PD.
• Utilizing a closed drainage system can substantially reduce the incidence of pancreatic fistulas.
• This study supports the adoption of closed drainage for improved patient safety and outcomes post-pancreaticoduodenectomy.
