What this trial studies

This clinical trial aims to evaluate the effectiveness of Esmesol, a proton pump inhibitor, compared to a placebo in preventing marginal ulcers in patients undergoing pancreaticoduodenectomy (PPPD). The study is a prospective multicenter trial conducted in Korea, focusing on patients with pancreatic, bile duct, or ampulla of Vater diseases. Participants will be randomly assigned to receive either Esmesol or a placebo, and their outcomes will be monitored to determine the incidence of marginal ulcers post-surgery.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 19 and older who are scheduled for pancreaticoduodenectomy and meet specific eligibility criteria.

Not a fit: Patients with a history of certain gastrointestinal diseases, previous gastric surgery, or those allergic to Esmesol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the occurrence of marginal ulcers in patients after pancreatic surgery, improving recovery and quality of life.

How similar studies have performed: While there have been studies on the use of proton pump inhibitors in various contexts, this specific approach to preventing marginal ulcers post-PPPD is relatively novel.
