title: [A case of idiopathic portal vein obstruction identified by severe bleeding after a routine hemorrhoid operation].
abstract: We report our experiences of a case of repeated bleeding after hemorrhoid ligation. A 53-year-old man underwent hemorrhoid ligation for internal hemorrhoids at another hospital. Postoperatively, he developed severe and repeated bleeding. Scanning revealed extrahepatic portal venous obstruction. The severe bleeding persisted after transfer to our institution, where we re-sutured the ligature and performed superior rectal artery embolism, leading to arrest of bleeding. The rectal varix arose due to portal hypertension, which resulted in the diagnosis of idiopathic extrahepatic portal vein obstruction.
