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).
