[Endoscopic extraction of a tumor prosthesis dislodged into the stomach]

Endoscopic pertubation of oesophagogastric neoplasms is an established method of palliative treatment. The dislocated plastic prosthesis may be removed with difficulties from the stomach endoscopically. A simple technique for endoscopic removal of the prosthesis is described. The tube can be precisely centred within the oesophageal lumen by use of an intestinal decompression tube and additional guidance by the endoscopic retraction forceps. Thus gross damage of the exophytic tumor tissue with bleeding or perforation sequelae can be avoided. Injury to the patient does not exceed that caused by an ordinary gastroscopy.
