A 64-year-old woman underwent gastroscopy and abdominal computed tomography, which revealed a 4.0 × 3.5 cm gastric gastrointestinal stromal tumor (GIST) in the anterior wall of the stomach ([ Fig. 1 a ]). After full evaluation, an endoscopic full-thickness resection technique was used to achieve complete resection ([ Fig. 1 b ]). It is very important to retrieve the complete specimen to allow for subsequent pathological evaluation; however, retrieval is difficult for specimen larger than 3.5 cm. Wu et al. successfully applied a balloon-assisted technique for removal of large esophageal foreign bodies [ 1 ]. Therefore, we applied this technique for endoscopic en bloc retrieval of a large gastric GIST specimen ([ Video 1 ]). Fig. 1 Endoscopic en bloc retrieval of a large gastric gastrointestinal stromal tumor (GIST) specimen using a transparent cap with a balloon. a A 4.0 × 3.5 cm gastric GIST was located in the anterior wall of the stomach. b The omentum was visible on the wound after complete resection. c A transparent cap with a balloon, which could be expanded to a maximum outer diameter of 4.0 cm, was used to assist retrieval. d The specimen had a volume of 4.0 × 3.5 × 3.5 cm and was retrieved en bloc.
