Achalasia is an esophageal motility disorder of unknown cause, characterized by aperistalsis of the esophageal body and impaired lower esophageal sphincter relaxation. Patients present at all ages, primarily with dysphagia for solids/liquids and bland regurgitation. The diagnosis is suggested by barium esophagram and confirmed by esophageal manometry. Achalasia cannot be cured. Instead, our goa...

A 68-year-old man diagnosed with Chagas disease, hypertension and type 2 diabetes mellitus was followed up at a quarterly hospital in the specialties of otolaryngology and gastroenterology because of a chronic clinical feature of dysphagia and odynophagia for solid foods, and a non-confirmed diagnosis hypothesis of chagasic megaesophagus. During complementary investigation he was submitted to l...

Abstract CASE DESCRIPTION In Latvia in 2014, acquired idiopathic megaesophagus (AIME) was observed increased numbers of dogs that consumed varieties 1 brand dog food. Within 2 years, 253 were affected. Australia November 2017, 6 working diet another food developed AIME. total, 145 Australian CLINICAL FINDINGS AIME diagnosed predominantly large-breed male (> 25 kg [55 lb]). Regurgitation, wei...

OBJECTIVES The aim of the study is to evaluate cervical esophagogastric anastomosis complications between mechanical device versus manual suture. METHOD Thirty patients with megaesophagus with grade III/IV submitted to the esophagectomy transmediastinal approach were reviewed with average age from 31 to 68 years. The reconstruction was performed by gastric transposition and with anastomosis i...

OBJECTIVE To identify and classify the radiographic patterns of megaesophagus in Chagas disease, as seen on esophagograms and chest X-rays. MATERIALS AND METHODS This was a prospective study of 35 patients diagnosed with esophageal disease via manometry. The changes found on esophagograms were stratified according to Rezende's classification, divided into four categories (grades I through IV)...

Medical records of 55 dogs with 1 or more vascular rings around the esophagus and trachea were reviewed to determine the nature and frequency of related vascular anomalies and to determine the reliability of tracheal deviation on radiographs for the diagnosis of persistent right aortic arch (PRAA). Fifty-two (95%) of the 55 dogs had PRAA. Of the 52 dogs with PRAA, 44% had coexisting compressive...

Patients with megaesophagus (ME) have increased prevalence of cancer of the esophagus. In contrast, a higher incidence of colorectal cancer is not observed in patients with megacolon (MC). MC is very common in some regions of Brazil, where it is mainly associated with Chagas disease. We reviewed the pathology records of surgical specimens of all patients submitted for surgical resection of MC i...

Gastroesophageal intussusception is a rare pathology characterized by an acute or intermittent invagination of the stomach into the lumen caudal to the thoracic esophagus, the pathogenesis is not well understood, although it is likely multifactorial. The mortality is high, associated with a late diagnosis and a rapid deterioration. A 4-month-old male domestic shorthair kitten presented for eval...

Meaningful evaluation of the heart is predicated on a sound knowledge of normal anatomy, physiology, and breed variations and adherence to principles of standardized technique and positioning to eliminate non-pathologic variables. Digital radiography has helped improve radiographic technique but appropriate animal positioning remains critical. The ribs and spine should be penetrated well enough...
