Endoscopic retrieval of a gastric trichobezoar

Figure 1 A transnasal esophagogastroduodenal endoscopy identified a long and large gastric trichobezoar extending into the duodenum.

Figure 2 A standard gastroscope (GIFQ260; Olympus, Tokyo, Japan) was used for retrieval. A gasper with 5-prolongs (Olympus, Tokyo, Japan), commonly used for retrieval of polyps excised endoscopically, was used to retrieve the gastric trichobezoar.

Figure 3 A net for collecting the removed colorectal polyps was used instead of a grasper for endoscopic retrieval.

Figure 4 The retrieved specimens were 1. 8 cm × 3.2 cm × 34 cm in length and 100 g in weight.
