RESUMO
OBJECTIVE: To determine the frequency of duodenal ulcer (DU), as well as other clinical characteristics occurring after endoscopic variceal ligation (EVL) of the esophagus. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: The First Affiliated Hospital of Fujian Medical University, Fuzhou, China, from April 2012 to April 2013. METHODOLOGY: A total of 47 patients with esophageal varices (EVr) who had also undergone EVL and gastroscopic follow-up within 3 months of the procedure was retrospectively analyzed. The status of Helicobacter pylori(Hp) infection, Child-Pugh classification, and the grades of portal hypertensive gastropathy (PHG) were collected. Sixty EVr patients without EVL treatment, but with clinical data available, served as the control group. RESULTS: The frequency of DU in the EVL group (29.8%, 14/47) was higher than the control group (6.7%, 4/60) (p=0.02). Hp infection rate in EVLgroup was 19.15% (9/47), while in control group was 21.67% (13/60) (p=0.813). Hp positive rate (12.5%, 1/8) in patients exhibited new DUs after EVL was comparable to the patients without DU in the EVL group (12.1%, 4/33) (p=1.00). Patients with DU after EVL received 18.79 ±8.48 of ligating bands, while in those who did not exhibit DUs received 13.85 ±6.47 (z = -2.042, p = 0.041). Logistic regression analysis showed that the occurrence of DU was not associated with age, gender, Child-Pugh classification, or the grade of PHG (p > 0.05). CONCLUSION: Esophageal EVL is associated with a higher frequency of developing DU, which is related to a larger number of applied bands but is not correlated with Hp infection status or other variables.
