Phytobezoar is the most common type of bezoar. It is composed of indigestible vegetable matter and is usually found in the stomach. Biliary phytobezoar is extremely rare and difficult to diagnose preoperatively. The pathogenesis is not clear, and there have been only a few reports of biliary bezoars associated with sphincteric impairment at the ampulla of Vater. Here, we present a report of biliary bezoar that resulted in jejunal obstruction. We were unable to identify the bezoar in the extrahepatic bile duct until it obstructed the small bowel lumen. To our knowledge, this is the first report of small bowel obstruction resulting from migration of a biliary bezoar.
植物性胃石是最常见的胃石类型。它由不可消化的植物物质组成,通常在胃中发现。胆源性植物性胃石极为罕见,术前难以诊断。其发病机制尚不清楚,仅有少数报道称胆石与壶腹括约肌功能障碍有关。在这里,我们报告了一例导致空肠梗阻的胆石。我们无法在肝外胆管中识别出胆石,直到它阻塞了小肠腔。据我们所知,这是首例因胆石迁移导致小肠梗阻的报告。
