The incidence and risk factors of marginal ulcers in the short and medium term in symptomatic post-pancreaticoduodenectomy patients ---- single-center experience.

Background: Marginal ulcer (MU) is one of the postoperative complications of pancreaticoduodenectomy (PD), which needs particular attention in postoperative treatments.
Methods: The data of 190 patients who underwent PD and follow-up gastroscopic review due to upper GI symptoms within two years were retrospectively analyzed. The incidence of MU and risk factors were analyzed based on personal history, surgical procedure, past medical history, postoperative complications, and other relevant indicators.
Results: The proportion of MU in patients who underwent endoscopic follow-up for upper gastrointestinal symptoms in the postoperative period in this cohort was 10.5% (20/190). Advanced age (69y vs. 59y, P ​= ​0.012), alcohol consumption (20% vs. 8.2%, P ​= ​0.03), and cigarette smoking (35% vs. 14.7%, P ​= ​0.022) were associated with an increased incidence of MU. Longer surgery time (276.5min vs. 240min, P ​= ​0.049), postoperative bleeding (10% vs. 1.8%, P ​= ​0.030), and failure to take antacid regularly postoperatively (75% vs. 97.1%, P ​= ​0.000) would increase the risk of MU; taking antacid regularly was an independent protective factor for postoperative anastomotic ulceration (OR: 0.091, CI: 0.022-0.383, P ​= ​0.001).
Conclusion: Advanced age, alcohol consumption, smoking, longer operation time, or postoperative extraluminal hemorrhage are associated with MU. Regular use of antacids is an independent protective factor against the development of MU.
