Gastric bezoar: another side effect of endoscopic variceal sclerotherapy.
Gastric bezoars were observed after esophageal variceal injection of polidocanol in 5 of 56 patients with alcoholic cirrhosis treated by endoscopic sclerosis. We suggest that endoscopic sclerotherapy could have induced a transient vagal injury resulting in delayed gastric emptying and subsequent bezoar formation. Although the volume of sclerosant (25-35 ml per session) and the length of the injector needle (4 mm) were the same in all patients, two reasons could explain the occurrence of bezoars in these five patients: a deeper injection of sclerosant, and a worsening of a preexistent vagal neuropathy due to diabetes mellitus and/or alcoholism.
