Self-expandable metallic stent-induced esophagorespiratory fistulas in patients with advanced esophageal cancer.

Background/aims: Self-expandable metallic stents (SEMSs) are widely adopted for the palliation of dysphagia in patients with malignant esophageal strictures. An important adverse event is the development of SEMS-induced esophagorespiratory fistulas (SEMS-ERFs). This study aimed to assess the risk factors related to the development of SEMS-ERF after SEMS placement in patients with esophageal cancer.

EUS-guided gastroenterostomy: Initial experience in a brazilian tertiary center.

Introduction: EUS-guided gastroenterostomy (EUS-GE) is a novel procedure for palliation of malignant gastric outlet obstruction (GOO). Our aim was to evaluate the outcomes of this technique in our initial experience.

Methods: Patients with GOO from our institute were included.

Clinical, endoscopic and manometric features of the primary motor disorders of the esophagus.

Background: Significant incidence, diagnostic difficulties, clinical relevance and therapeutic efficacy associated with the small number of publications on the primary esophageal motor disorders, motivated the present study.

Aim: To determine the manometric prevalence of these disorders and correlate them to the endoscopic and clinical findings.

Methods: A retrospective study of 2614 patients, being 1529 (58.
