Gastric peroral endoscopic myotomy (GPOEM) for severe gastroparesis after lung transplantation: A promising minimally invasive option.

After lung transplantation (LT), gastroparesis is frequent, occurring in 25-63% of cases and leading to pulmonary infections. In refractory disease, classical management has demonstrated limited efficacy. Gastric peroral endoscopic myotomy (G-POEM) is a recently developed safe and effective procedure that has been performed here on five patients with severe post-LT gastroparesis.
In all patients, the diagnosis was confirmed by disturbed gastric emptying scintigraphy and GCSI calculation showing severe disease. Upper gastrointestinal endoscopies confirmed the absence of organic lesions. All patients were informed about the procedure and signed informed consent forms. The procedure consisted of performing an endoscopic pyloromyotomy under general anesthesia.
The patients were between 35 and 64 years of age. Four had chronic disease, starting approximately 1 year following LT, and one had acute, severe gastroparesis requiring intubation in the intensive care unit. All patients underwent G-POEM after failure of medical treatment, without any complications. Three of the patients with chronic disease improved; they resumed a normal diet and gained weight. The patient with acute disease was discharged within a few days following the procedure and resumed oral intake.
G-POEM is promising for managing post-LT refractory gastroparesis and should be further evaluated.
