Impact of endoscopic ultrasound-guided transmural drainage for postoperative pancreatic fistula after pancreatic surgery.

Objectives: Postoperative pancreatic fistula (POPF) is a major cause of morbidity after pancreatic surgery. Recently, endoscopic ultrasound-guided transmural drainage (EUS-TD) has been widely used to manage pancreatic pseudocysts after acute pancreatitis. Several studies have reported the effectiveness of EUS-TD for POPF, although there is insufficient evidence regarding the performance of EUS-TD for POPF. We herein report on the safety, efficacy, and appropriate timing of EUS-TD for POPF compared with conventional percutaneous intervention.

Methods: Eight patients who underwent EUS-TD of POPF and 36 patients who underwent percutaneous intervention were retrospectively enrolled. Clinical outcomes, including technical success, clinical success, and complications, were analyzed among the two groups.

Results: In terms of clinical outcomes between the EUS-TD and percutaneous intervention groups, significant differences were observed in the number of interventions (1 vs. 4, = 0.011), period of clinical success (6 days vs. 11 days, = 0.001), incidence of complications (0 vs. 3, = 0.021), postoperative hospital stays (27 days vs. 34 days, = 0.027), and recurrence of POPF (0 vs. 5, = 0.001).

Conclusions: EUS-TD for POPF appears to be safe and technically feasible. This approach should be considered a therapeutic option in patients with POPF after pancreatic surgery.
