Endoscopic diode laser therapy for gastric hyperplastic polyps in cirrhotic patients.

Abstract

Purpose Endoscopic polypectomy to remove gastric hyperplastic polyps in cirrhotic patients is associated to a high risk of postprocedural bleeding. The current study set out to examine the effect of diode laser therapy used to treat this type of polyps in cirrhotic patients. Methods This single-center study retrospectively examined the data of cirrhotic patients with macroscopic bleeding or anemia who underwent diode laser therapy (940 nm wave length, 30-W power setting in continuous mode) to remove histology-confirmed hyperplastic gastric polyps. Results A total of 222 polyps (mean diameter 10 ± 8 mm) were treated in 55 patients who were included in the study. No complications such as bleeding or perforations were reported. After a mean of 5 ± 4 sessions, 31 patients (56%) were completely healed. In 16 patients (29%), there was only a partial response (mean polyp reduction diameter of 64 ± 15%), while 8 (15%) patients did not respond to treatment. Statistically significant better results were noted in the patients who underwent ≥ 2 laser sessions. Hemoglobin levels and number of blood transfusions required were not statistically different after treatment. After a mean study period of 21 ± 17 months, polyp recurrences were noted in 11 patients (20%), but none of the polyps had degenerated. Conclusion Diode laser therapy was found to be a safe treatment for hyperplastic polyps in cirrhotic patients. Due to the presence of others bleeding lesions in cirrhotic patients, this treatment did not have an impact on anemia and transfusion requirements.
