Frequency of Peptic Ulcer Disease in Patients with Chronic Liver Disease Presenting with Upper Gastrointestinal Bleeding

Abstract

Background: Peptic ulcer disease (PUD) is a significant cause of morbidity and mortality worldwide, particularly in patients with chronic liver disease (CLD). The occurrence of upper gastrointestinal bleeding (UGIB) in CLD patients presents a serious complication, often requiring urgent medical intervention. Objective: The main objective of this study was to determine the frequency of peptic ulcer disease in patients with chronic liver disease presenting with upper gastrointestinal bleeding. Methods: This retrospective observational study was conducted at Ayub Teaching Hospital, Abbottabad, from 2021 to 2023. Data were collected from 105 patients diagnosed with chronic liver disease who presented with symptoms of upper gastrointestinal bleeding. The diagnosis of CLD was confirmed through clinical evaluation, biochemical tests, imaging studies, and/or liver biopsy. Patients included were aged 18 years and above and presented with UGIB evidenced by hematemesis, melena, or both. Exclusion criteria were individuals with bleeding disorders unrelated to CLD and those who did not undergo endoscopic evaluation. Data collection involved demographic information, clinical history, duration and etiology of CLD, comorbid conditions, and UGIB presentation. Upper gastrointestinal endoscopy was performed on all patients to identify the source of bleeding. Statistical analysis was performed using SPSS version 25, with a p-value of less than 0.05 considered statistically significant. Results: The study included 105 patients, with a mean age of 55.3±3.27 years; 65 (61.9%) were male, and 40 (38.1%) were female. The etiologies of CLD were viral hepatitis (42.9%), alcoholic liver disease (28.6%), non-alcoholic fatty liver disease (19.0%), and other causes (9.5%). Clinical presentations of UGIB included hematemesis (66.7%), melena (23.8%), and both (9.5%). Endoscopic findings revealed that 35 patients (33.3%) had peptic ulcer disease, with 20 (57.1%) having duodenal ulcers and 15 (42.9%) having gastric ulcers. Other sources of UGIB included esophageal varices (38.1%), gastric varices (14.3%), erosive gastritis (9.5%), and malignancies (4.8%). Associated risk factors for PUD included NSAID use (42.9%), smoking (28.6%), and coexisting portal hypertension (71.4%). The mean size of ulcers was 10.2 mm. Endoscopic therapy was utilized in 71.4% of cases, with pharmacological treatment primarily including proton pump inhibitors (85.7%). Complications included rebleeding within 7 days (14.3%) and the need for surgical intervention (5.7%). The mean hospital stay was 7.8 days, and in-hospital mortality was observed in 8.6% of patients. Conclusion: Peptic ulcer disease represents a substantial yet manageable complication in patients with chronic liver disease presenting with upper gastrointestinal bleeding. Prompt recognition and targeted therapeutic interventions are crucial for optimizing outcomes in this high-risk population.
