消化道出血的一个不明原因：在没有门脉高压的情况下，肌内注射奥曲肽治疗复发性十二指肠静脉曲张出血。An obscure cause of gastrointestinal bleeding: Recurrent duodenal variceal hemorrhage treated with intramuscular octreotide in the absence of portal hypertension.-医云文献数字医云科研云海量医学决策数据服务

Abstract：

Duodenal varices (DVs) are ectopic gastrointestinal varices (ECVs) associated with portal hypertension (PH). We present the case of an 82-year-old woman who presented with symptomatic anemia secondary to DV hemorrhage diagnosed on oesophagogastroduodenoscopy. This lesion was treated with endoscopic adrenaline injection and clip application. The patient re-presented on multiple occasions with bleeding recurrence localized to the duodenum, which was managed with intramuscular octreotide and oral beta-blockade resulting in sustained remission of bleeding. This case highlights a rare cause of upper gastrointestinal hemorrhage and highlights the value of somatostatin analogues for conservative treatment of DVs.

摘要：

十二指肠静脉曲张（DV）是与门脉高压（PH）相关的异位胃肠道静脉曲张（ECV）。我们介绍了一名82岁女性的病例，该女性在食管胃十二指肠镜检查中被诊断为因DV出血而出现有症状的贫血。该病变采用内镜下肾上腺素注射和夹子应用治疗。患者多次出现十二指肠局部出血复发，通过肌内奥曲肽和口服β-阻滞剂治疗，导致出血持续缓解。该病例突出了上消化道出血的罕见原因，并强调了生长抑素类似物对DV保守治疗的价值。
