Abstract
|
|
|
|
Therapeutic radiation therapy has developed new technologies that use a high dose of radiation with three- dimensional targeting for a few days instead of conventional radiation therapy that uses small doses of radiation for a longer period of time. A Cyberknife is an image- guided robotic system for stereotactic radiosurgery. The Cyberknife was first developed for the treatment of intracranial lesions, and recently has been used for tumors in the chest and abdomen. A Cyberknife can use a high dose of radiation for treatment of a hepatocellular carcinoma and can be employed to minimize radiation injury around the tumor. However, in a large tumor, the therapeutic efficacy is reduced and injury can occur around the organs. We report a case of acute injury in the stomach and duodenum after Cyberknife treatment of a hepatocellular carcinoma near the hepatic portal area. (Korean J Gastrointest Endosc 2007;35:262-266)
