Abstract
BACKGROUND: Acute necrotizing pancreatitis (ANP) is complicated with segmental portal hypertension (PHT) and formation of venous collaterals. Presence of collaterals in vicinity of endoscopic transmural tract can lead to potentially catastrophic situation. Here, we report safety and outcome of EUS-guided transmural drainage of walled-off pancreatic necrosis (WOPN) in patients with PHT and intra-abdominal collaterals. METHODS: Retrospective analysis of collected database of patients (n=18; age 40.94±8.43 years; 17 males) who underwent EUS-guided transmural drainage of WOPN and had PHT with collaterals. RESULTS: Etiology of ANP: alcohol in 14 and gallstones in 3 patients. Mean size of collection was 10.7±3.5 cm, and all 18 patients had splenic vein thrombosis with 1 patient also having portal vein thrombosis. Drainage was not feasible in 1 patient as no window free of collaterals could be found. One patient with gastric variceal bleeding underwent drainage after successful obliteration of varix with glue. Multiple plastic stents were placed in 15 patients and fully covered self-expanding metallic stent (FCSEMS) in 1 patient and 1 patient required direct endoscopic necrosectomy (DEN). Mean procedures required were 3 ± 0.79 and time to resolution was 4.4 ± 1.3 weeks. One patient had post-drainage bleeding that was successfully managed with intravenous terlipressin and intermittent irrigation via nasocystic catheter. Successfully treated patients have been asymptomatic over follow up period of 15.65±12.2 weeks. CONCLUSION: EUS-guided drainage of WOPN seems to be safe and effective in patients with portal hypertension and intra-abdominal collaterals.
