case_images: Images of the trichobezoar stuck in the stomach and attempts of endoscopic removal. (A) A trichobezoar was occupying the lumen of the stomach. (B) The trichobezoar contained synthetic yarn. (C) A variceal ligator cap was attached to provide more flexible maneuvering space for positioning the hairball in the cap. (D) Grasping forceps were applied to loosen the tightly intertwined forces. (E) Piecemeal removal of the hair strands and yarn by using grasping forceps. (F) Complete removal of the trichobezoar.

case_images: A 10 cm x 10 cm mass consisting of hair mixed with yarn was found, occupying the lumen of the stomach (Figures 1A,B). The variceal ligator cap enabled a more flexible maneuvering space (Figure 1C). It was used to position the hair strands into it when the grasping forceps was repeatedly pulling the densely impacted hairball back and forth in order to loosen it (Figure 1D). Cautiously, the hair strands and yarn were removed piecemeal (Figure 1E). The hairball and yarn were completely removed in about 20 passes (Figure 1F).
