要旨　患者は63歳，女性．腹痛，下痢，発熱のため入院．左下腹部痛，defenseを認めたため憩室炎を疑い抗生剤を投与し，症状は消失したが，5日目より再度発熱し，腹水を認めたため，手術施行．X線的に下行結腸に竹の節状変形を認めた．われわれは動物実験でショックによる血流障害が原因と思われる竹の節状変形を経験したが，本症例も憩室炎→エンドトキシンショックによる虚血性疾患と診断した．

　A 63-year-old woman was hospitalized because of abdominal pain, diarrhea and fever. Since left lower abdominal pain and muscular defense were noted, diverticulitis was suspected. With administration of antbiotics, the symptoms were relieved. However fever developed again on the 5th hospital day and ascites was noted. Therefore operation was performed. X-ray examination revealed bamboo-joint sign in the descending colon. In the past we had encountered bamboo-joint sign considered indicative of blood flow disturbance in shock. Based on such an experience, we made a diagnosis of ischemic disease due to diverticulitis-endotoxin shock in this case.
