RESUMO
GOALS: To determine the prevalence, severity, and outcome of gastroparesis after heart and lung transplantation (HLT). STUDY: Ten patients (five women; age range, 27-57 years) underwent HLT at Temple University Hospital from 1996 to 1999. The charts of these patients were reviewed, including results from gastric emptying scans and upper endoscopies. Symptoms were assessed with a standardized questionnaire. RESULTS: The indications for HLT included pulmonary hypertension in six patients, Eisenmenger syndrome in two, and dilated cardiomyopathy and congenital heart disease in two. Four patients died before the start of this clinical analysis. The six surviving patients constituted our study population. The patients' posttransplantation follow-up period ranged from 1.4 to 4.4 years (average, 2.6 years). Five patients (83%) were symptomatic with nausea, vomiting, and postprandial abdominal distension. Solid phase gastric emptying was delayed in all five patients with mean gastric retention of 93% at 2 hours (normal <50%). Patients generally did not respond to prokinetic agents. Four patients required pyloroplasty with J tube placement for symptom control, nutrition, and delivery of immunosuppressive medication. CONCLUSIONS: There is a high prevalence of symptomatic gastroparesis in patients after HLT. The gastroparesis is severe and often resistant to prokinetic agents.
