RESUMO
BACKGROUND: Clinically relevant (CR) postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) are common. Endoscopic treatment (ET) has only scarcely been explored. The aim of this study was to evaluate risk factors for CR POPF after DP and the efficacy of ET in adjunct to standard therapy. METHODS: Consecutive patients without previous pancreatic surgery who underwent DP between 2011 and 2020 were evaluated, analyzing risk factors for CR POPF. The choice and performance of ET, main pancreatic duct (MPD) stenting, was not standardized. Healing time and complications after ET were registered. RESULTS: 406 patients underwent DP, CR POPF occurred in 29.6%. ET was performed in 17 patients 27 days (median) after index surgery. Risk for CR POPF was increased in ASA-PS 1-2 patients, MPD ≤ 3 mm, procedure time ≥ 3 h, and CRP ≥ 180 on postoperative day 3. POPF resolved with standard treatment after 32 days and 59 days in the ET group (p < 0.001). There was one mortality in the ET-group (not procedure related). Mild post-ERCP pancreatitis occurred in three patients. CONCLUSIONS: CR POPF is common after DP. Long operating time, a narrow MPD, low ASA score, and high postoperative CRP were risk factors for CR POPF. ET was not beneficial but proper evaluation was not possible due to few patients and non-standardized treatment. Complications after ET appeared mild.
