Late-onset severe biliary bleeding after endoscopic pigtail plastic stent insertion

World Journal of Gastroenterology 2017年第4期23卷 735-739页

Here, we report our experience with a case of severe biliary bleeding due to a hepatic arterial pseudoaneurysm that had developed 1 year after endoscopic biliary plastic stent insertion. The patient, a 78-year-old woman, presented with hematemesis and obstructive jaundice. Ruptured hepatic arterial pseudoaneurysm was diagnosed, which was suspected to have been caused by long-term placement of an endoscopic retrograde biliary drainage(ERBD) stent. This episode of biliary bleeding was successfully treated by transarterial embolization(TAE). Pseudoaneurysm leading to hemobilia is a rare but potentially fatal complication in patients with long-term placement of ERBD. TAE is a minimally invasive procedure that offers effective treatment for biliary bleeding.

AIM To investigate usefulness of triple therapy with vonoprazan,a potassium ion-competitive acid blocker and antibiotics,for Helicobacter pylori(***) *** The *** eradication rate was examined in 2507 patients(2055 undergoing primary eradication and 452 undergoing secondary eradication,excluding patients with subtotal gastrectomy) at the Japanese Red Cross Kyoto Daiichi Hospital from March 2013 to September *** patients treated from March 2013 to February 2015,a proton pump inhibitor(PPI) was used to reduce acid secretion,while vonoprazan was used after March *** success rates of the 2 regimens(PPI + amoxicillin + clarithromycin/metronidazole,or vonoprazan + amoxicillin + clarithromycin/metronidazole) were *** The success rate of primary *** eradication was significantly higher in the vonoprazan *** stratified by the underlying disease,a significant increase of the *** eradication rate was observed in patients with chronic gastritis.A significantly lower *** eradication rate was observed in younger patients compared to older patients in the PPI group,but there was no difference according to age in the vonoprazan *** the otherhand,the success rate of secondary eradication was similar at approximately 90% in both *** Vonoprazan is very useful for primary eradication of ***,and may become a first-line acid secretion inhibitor instead of PPIs.
