An alternative endoscopic treatment for massive gastric bezoars: Ho:YAG laser fragmentation

Abstract

Gastrointestinal (GI) bezoars are aggregates of indigestible material that occur mainly in patients with altered GI anatomy (i. e. bariatric surgery, partial gastrectomy) and/or motility disorders (i. e. gastroparesis, drug-induced delayed gastric emptying). Other risk factors are high fiber intake, psychiatric diseases, and severe constipation [1].
