RESUMEN
Gastrointestinal duplication cysts are infrequent congenital abnormalities. 2% to 12% of these abnormalities are localized in correspondence of the duodenum. This disease rarely remains asymptomatic until adulthood. We present a case of A 62-yearold woman with intermittent upper abdominal pain and nausea, describing the diagnostic and therapeutic route.
RESUMEN
Objective To investigate the diagnostic value of endoscopic ultrasonography (EUS) for duodenal cysts.Methods Clinical manifestations, results of conventional gastroscopy and EUS, as well as follow-up, of patients with duodenal cysts were retrospectively analyzed.Results A total of 105 patients with duodenal cysts presented with no lesion-related symptoms, but displayed characteristic imaging changes under EUS, which could reveal the origin, size and nature of duodenal cysts, and differentiate it from other submucosal lesions.A maximum follow-up of 5 years showed no changes in duodenal cysts.Conclusion Duodenal cyst is a benign disease, and EUS plays a very important role in diagnosis of the disease.
