Bezoars are the uncommon result of the ingestion of indigestible or poorly digested substances, which form a solid mass within the gastrointestinal tract. They are classified based on their content and include phytobezoars (plant fibers), trichobezoars (hair), and lactobezoars (milk curds). They may occur in combinations like trichophytobezoars, and can result from virtually anything capable of forming concretions within the gastrointestinal tract, including medications. They are found mainly in the stomach and are rare in the colon. Bezoars are uncommon in children. We report the rare case of a sunflower-seed bezoar impacted at the anal verge in a 6-year-old boy who presented initially with acute gastroenteritis. He required removal of the impaction under sedation.
胃石是摄入难以消化或消化不完全的物质后在胃肠道内形成固体团块的罕见结果。它们根据其成分进行分类，包括植物性胃石（植物纤维）、毛发胃石（毛发）和乳凝块胃石（乳凝块）。它们可能以毛发植物性胃石等组合形式出现，几乎任何能够在胃肠道内形成结石的物质都可能导致胃石形成，包括药物。胃石主要见于胃，在结肠中罕见。胃石在儿童中并不常见。我们报告了一例罕见病例，一名6岁男孩肛门边缘嵌顿有葵花籽胃石，最初表现为急性肠胃炎。他需要在镇静状态下取出嵌顿物。
