Post-infectious gastroparesis: clinical and electerogastrographic aspects.
OBJECTIVE
Post-infectious gastroparesis (PIGP) is a subgroup of idiopathic gastroparesis. The aim of this study was to identify post-viral gastroparesis and to characterize clinical and electrogastrographic aspects of the disease and their usefulness as a diagnostic tool.


METHODS
Patients diagnosed with gastroparesis were defined as PIGP if they had a clear history of an acute viral illness prior to the development of their symptoms. All patients underwent evaluation of gastric emptying and electrogastrography (EGG).


RESULTS
Seven patients met the criteria for diagnosis of PIGP. Patients' age ranged from 3 months to 47 years. A specific virus was identified in two patients (one cytomegalovirus [CMV] and one Epstein-Barr virus [EBV]). EGG was pathological in six out of seven patients. In four out of seven patients, symptoms resolved spontaneously within 4 weeks to 12 months, three patients had improved but were still symptomatic at the time of the writing of this work.


CONCLUSIONS
We conclude that post-infectious gastroparesis is an uncommon and often over looked condition. It is self-limiting in most cases. EGG is pathological in most patients.
