高齢者早期胃癌ESDにおける偶発症

Adverse Events Associated with Endoscopic Submucosal Dissection in Elderly Patients with Early Gastric Cancer

要旨●本稿では，高齢者早期胃癌に対するESDの治療成績について，偶発症を中心に検討を行った．高齢者では併存疾患が多く，年齢別の偶発症の発生頻度は高い傾向を認めるが有意差はなかった．内視鏡治療自体は可能で，偶発症が生じなければ非高齢者と同程度の入院期間で対応可能である一方，ひとたび偶発症が生じると，より長期の入院を必要としていた．アスピリン，シロスタゾール以外の抗血栓薬では出血時期が遅延し，ヘモグロビン減少量が多く，特に留意が必要と思われる．

　Many elderly individuals exhibited comorbidities, and the frequency of adverse events as per age tended to be high, but no significant differences were noted. Endoscopic treatment can be performed on elderly patients with early gastric cancer. If no adverse event occurred, the length of hospital stay of these patients was similar to that of non-elderly individuals. However, once an adverse event developed, they required prolonged hospitalization. It is noteworthy that the administration of antithrombotic drugs other than aspirin or cilostazol causes delayed onset of hemorrhage and remarkable decrease in hemoglobin levels.
