RT Journal Article T1 Digestive involvement in a patient with Lambert-Eaton syndrome. A1 Díaz Alcázar, María Del Mar A1 Ruiz-Rodríguez, Antonio José A1 Martín-Lagos Maldonado, Alicia AB We present the case of a 50-year-old male diagnosed with myasthenia gravis, secondary to thymoma or Lambert-Eaton syndrome during the study of repeated vomiting. Gastrointestinal symptoms persisted despite the treatment of the thymoma. He suffered from sigma volvulus that required sigmoidectomy 9 years after diagnosis. Neuromuscular junction disorders are not characterized by gastrointestinal involvement, as in our case. They have previously sporadically been related to intestinal motility dysfunction.
