Treatment of P-J strictures results in poor outcomes. Although conventional EUS that has an oblique view is not suitable for such patients, forward-viewing EUS (FV-EUS) may become a useful option. This study aimed to evaluate the feasibility and efficacy of FV-EUS in patients who have undergone PD.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>Patients with PD who were scheduled to undergo diagnosis and treatment using FV-EUS for H-J or P-J lesions were enrolled in this single-center prospective study. After observation of the P-J and H-J using FV-EUS according to a predetermined protocol, treatment using FV-EUS was performed as needed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>A total of 30 patients were enrolled, and FV-EUS was used to observe P-J and H-J in 24 and 28 patients, respectively. The detection rates of P-J and H-J by endoscopy were 50% (12\/24) and 96.4% (27\/28), respectively, and by EUS were 70.8% (17\/24) and 100% (28\/28), respectively. Of these, P-J and H-J were found by endoscopy only after EUS observation in 3 and 1 patient, respectively. The success rates of endoscopic treatment using FV-EUS were 66.7% (2\/3), 95.2% (20\/21), and 25% (1\/4) for benign P-J strictures, benign H-J strictures, and tumor recurrence, respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Endoscopic treatment using FV-EUS is feasible and effective for patients after PD.
