Diagnostic and therapeutic challenges in the management of obstructive defecation.

Chronic constipation is a very common disease in daily clinical practice with a significant deterioration in quality of life that increases when associated with obstructive defecation. For this reason, we believe that the case presented here can improve our knowledge of these problems.

Endoscopic submucosal dissection (ESD) of antral subepithelial lesion suspected of malignancy.

Subepithelial gastric tumours comprise a heterogeneous group of lesions. Endoscopic ultrasonography with fine-needle aspiration (EUS-FNA) is a useful approach but cannot always offer a definitive diagnosis to guide future therapeutic decisions. In the case we describe, biopsy samples of an antral subepithelial lesion and cytological analysis obtained with an EUS-FNA suggested the diagnosis of an adenocarcinoma. Endoscopic submucosal dissection (ESD) allowed en bloc resection of the tumour ensuring diagnosis and providing a definitive treatment.
