EUS-guided drainage in the management of postoperative pancreatic leaks and fistulas (with video)

Background and aims: Postoperative pancreatic leakage and fistulae (POPF) are a leading adverse event after partial pancreatic resection. Treatment algorithms are currently not standardized. Evidence regarding the role of endoscopy is scarce.

Methods: One hundred ninety-six POPF patients with (n = 132) and without (n = 64) concomitant pancreatic fluid collections (PFCs) from centers in Berlin, Kiel, and Dresden were analyzed retrospectively. Clinical resolution was used as the primary endpoint of analysis.

Results: Analysis was stratified by the presence or absence of a PFC because these patients differed in treatment pathway and the presence of systemic inflammation with a median C-reactive protein of 30.7 mg/dL in patients without a PFC versus 131.0 mg/dL in patients with a PFC (P = 3.4 × 10^-4). In patients with PFCs, EUS-guided intervention led to resolution in a median of 8 days as compared with 25 days for percutaneous drainage and 248 days for surgery (P = 3.75 × 10^-14). There was a trend toward a higher success rate of EUS-guided intervention as a primary treatment modality with 85% (P = .034), followed by percutaneous drainage (64%) and surgery (41%). When applied as a rescue intervention (n = 24), EUS led to clinical resolution in 96% of cases. In patients without PFCs, EUS-guided internalization in a novel endoscopic technique led to resolution after a median of 4 days as compared with 51 days for a remaining surgical drainage (P = 9.3 × 10^-9).

Conclusions: In this retrospective analysis, EUS-guided drainage of POPF led to a more rapid resolution. EUS may be considered as a viable option in the management of PFCs and POPF and should be evaluated in prospective studies.
