Lactobezoar is a foreign body produced in the gastrointestinal tract by the presence and accumulation of undigested milk curds. It is seen most commonly in low-birth-weight, premature infants fed with 24-calorie formulas. Conventional therapy includes withholding feedings, repeated gastric lavage, and maintenance of nutrition and hydration by the parenteral route. Most cases respond to this regimen within 48 to 72 hours. We present a case of gastric lactobezoar in a premature, small for gestational age infant who was fed a 24-calorie formula but failed to respond to conventional therapy for more than a week. Historical background and pathophysiology of lactobezoar are discussed.
乳石是胃肠道中因未消化的乳凝块存在和积聚而产生的异物。它最常见于喂食24千卡配方奶的低体重早产儿。传统治疗方法包括停止喂食、反复洗胃以及通过肠外途径维持营养和水合作用。大多数病例在48至72小时内对该治疗方案有反应。我们报告一例孕周小的早产儿胃乳石病例，该患儿喂食24千卡配方奶，但对传统治疗一周多无反应。本文讨论了乳石的历史背景和病理生理学。
