Delayed gastric emptying can be due to muscular, neural, or humoral abnormalities. In the absence of an identified cause, gastroparesis is labelled as idiopathic. We present the case of a patient with severe idiopathic gastroparesis. Pharmacological approaches failed, as well as reduction in gastric emptying resistance with pyloric injection of botulinum toxin and pyloroplasty. Therefore, subtotal gastrectomy was performed. Histological and immunohistochemical study of the resected specimen showed hypoganglionosis, neuronal dysplasia, and a marked reduction in both myenteric and intramuscular interstitial cells of Cajal. To our knowledge, this is the first time these rare histological findings have been described in a patient with idiopathic gastroparesis.
胃排空延迟可能是由于肌肉、神经或体液异常所致。在未发现明确病因的情况下,胃轻瘫被标记为特发性。我们报告一例严重特发性胃轻瘫患者的病例。药物治疗方法无效,幽门注射肉毒杆菌毒素及幽门成形术以降低胃排空阻力的方法也无效。因此,实施了胃次全切除术。对切除标本进行的组织学和免疫组化研究显示神经节减少、神经元发育异常,以及肌间和肌内 Cajal 间质细胞显著减少。据我们所知,这是首次在特发性胃轻瘫患者中描述这些罕见的组织学发现。
