Blind loop syndrome (BLS) is a clinical condition characterized by bacterial overgrowth and stasis within intestinal blind loops, which may result from anatomical abnormalities such as diverticula, fistulae, or surgical anastomoses. While end-to-side and side-to-side intestinal anastomoses are common surgical techniques, the latter has been associated with a higher risk of BLS due to the potential formation of stagnant segments. This case report presents a rare instance of small intestinal obstruction caused by large fecalith formation within a blind loop 1 year after side-to-side anastomosis. The clinical presentation, diagnostic approach, and management strategies are discussed in detail. This report highlights the importance of surgical technique selection and standardization in preventing BLS-related complications, providing valuable insights for clinical practice.
盲袢综合征（BLS）是一种临床病症，其特征为肠道盲袢内细菌过度生长和淤滞，这可能由憩室、瘘管或手术吻合等解剖学异常引起。虽然端侧和侧侧肠吻合术是常见的外科技术，但由于可能形成停滞段，后者与BLS的风险较高相关。本病例报告呈现了一例罕见的小肠梗阻病例，该梗阻由侧侧吻合术后1年盲袢内形成巨大粪石所致。详细讨论了临床表现、诊断方法和管理策略。本报告强调了手术技术选择和标准化在预防BLS相关并发症中的重要性，为临床实践提供了有价值的见解。
