Background and Objectives: For the treatment of pancreatic duct stenosis due to chronic pancreatitis (CP) or postoperative (PO) stenosis, endoscopic procedures are usually the first choice. In cases of failure of the recommended treatment by ERCP, anastomosis between the Wirsung duct and the stomach or duodenum can be performed under EUS guidance. The objective of this retrospective study was to compare the outcomes of pancreatico-gastric or pancreaticoduodenal anastomosis under EUS for PO stenosis versus CP stenosis. Subjects and Methods: This was a retrospective, single-center, consecutive case study of patients who underwent EUS-guided Wirsungo-gastric/bulbar anastomosis. Results: Forty-three patients were included. Twenty-one patients underwent treatment for PO stenosis, and 22 patients underwent treatment for CP stenosis. The technical success rate was 95.3% (41/43), with 100% in cases of PO stenosis and 90.9% in cases of CP stenosis. The clinical success rate was 72.5% (29/40): 75% (15/20) in cases of PO stenosis and 70% (14/20) in cases of CP stenosis. The overall morbidity rate was 34.9% (15/43). The main complication was postprocedural pain, occurring in 20.9% (9/443) of patients. The rate of stent migration or obstruction was 27.9% (12/43). There was no difference in patient outcomes or morbidity according to the etiology of the stenosis. The median follow-up duration in this study was 14 months. Conclusions: EUS-guided Wirsungo-gastric/duodenal anastomosis is a feasible, minimally invasive, safe, and relatively effective procedure. The rates of technical success, clinical success, and complications were not different between patients with PO and CP stenosis. However, the follow-up period was too short to assess recurrent symptoms in these patients.
