◆要旨:患者は73歳,男性.1か月前から続く心窩部痛を主訴に救急外来を受診した.採血で貧血を認め緊急上部消化管内視鏡を施行し,約10cm大の単発巨大胃石と活動期の胃潰瘍を複数認め加療目的で入院となった.プロトンポンプ阻害薬の点滴と絶食による保存的治療で症状は軽快したが,胃石の硬さと大きさから内視鏡的治療は困難と判断し,手術の方針とした.第20病日,腹腔鏡下に胃を切開し胃石を摘出した.胃石は12×5×5cmで,内部は橙黄色であり柿胃石が疑われた.術後経過は良好で術後6日目より食事を開始し,13日目に退院となった.腹腔鏡下での胃石摘出術の報告は少なく,文献的考察を含めて報告する.
A 73-year-old man was admitted to our hospital for epigastric pain. He had tarry stools and laboratory data included blood hemoglobin value of 8.5 g/dl. Upper gastrointestinal endoscopy demonstrated a large bezoar and multiple gastric ulcers. With the diagnosis of gastric ulcer due to a giant bezoar, he was treated with proton pump inhibitor. The bezoar was approximately 10cm in diameter and the surface was too difficult to fragment. Therefore, he underwent laparoscopic gastrotomy and bezoar removal on hospital day 20. The bezoar was grayish black and elastic soft, and measured 12×5×5 cm. He was discharged on the 13th postoperative day, and remains well without recurrence. A giant bezoar seems to be a good indication for laparoscopic surgery.
