A bezoar is the result of indigestible material that accumulates in the digestive tract, and represents 1 % of abdominal pathologies. Trichobezoar is a variant that is characterized by the ingestion of hair, nails, or eyebrows. It is frequently found in young women with associated psychiatric disorders [1]. It is suggested that the hair is trapped in the gastric folds and retained due to insufficient surface friction, which is necessary for propulsion [2].

A 41-year-old woman, with a history of generalized anxiety disorder, manifesting as trichomania and trichophagia, consulted for abdominal pain in the epigastric region associated with vomiting of “coffee grounds.” An upper gastrointestinal endoscopy revealed an accumulation of hair in the stomach, extending from the fundus, along the greater curvature, to the antrum ([Fig. 1]). This huge mass of hair, which partially obstructed the gastric lumen ([Fig. 2]), was impossible to remove endoscopically. Surgical colleagues took the patient to the operating room to perform gastrotomy and trichobezoar extraction ([Fig. 3], [Video 1]).

This case is interesting for several reasons. First, despite many publications of trichobezoar, there are few videos depicting this rare pathology. Second, we provide a detailed description of the endoscopic and surgical findings, and the steps required to resolve this uncommon but potentially life-threatening condition. Endoscopy is the most sensitive method for diagnosis of trichobezoars but has a low efficacy for treatment [2]. The video recording clearly depicts the dilated stomach with thin gastric wall, which portends a high risk for endoscopic attempts at extraction.

The treatment of choice is surgical by wide gastrotomy and extraction of the bezoar, although in some cases endoscopic extraction may be attempted. However, for cases where the trichobezoar occupies more than 50 % of the gastric chamber or extends into the duodenum the approach must be surgical [3].
