A 54-year-old Hispanic male presented to the clinic with chronic dyspepsia and uncontrolled reflux symptoms not responding to acid-suppression therapy with a proton pump inhibitor (PPI). His past history was remarkable for sleeve gastrectomy one year previously. PPI therapy was stopped two weeks prior to endoscopy to promote the yield of a Helicobacter pylori (H. pylori) test. Esophagogastroduo...

BACKGROUND An experimental study showed that thyropharyngeal, cricopharyngeal and cervical esophageal muscles of rabbits with iron deficiency anemia had morphological changes similar to those observed in muscular dystrophy, causing myastenic changes in muscles involved in swallowing. Our hypothesis is that patients with iron deficiency anemia may have a decrease in esophageal contractions with ...

A new percutaneous insertion technique for esophageal feeding tubes in cats is presented. The technique has been successfully applied in 12 feline patients. The placement technique is relatively simple, takes approximately five minutes to perform, and requires a scalpel blade, a curved hemostat, and an applicator for the insertion of the feeding tube. In contrast to other esophageal tube placem...

Jejuno-jejunal intussusception is a rare complication of feeding jejunostomy tube placement. A case of one year old child who underwent gastric pull-up for complicated tracheo-esophageal fistula had jejunojejunal intussusception induced by Witzel’s feeding jejunostomy tube; is discussed with review of literature.

Intramural esophageal dissection is a rare complication of eosinophilic esophagitis. Only three cases in adults have been described [1–3]. The residual mucosal septum could be treated with endoscopic section [4,5]. We report on the first pediatric case to be treated conservatively for intramural esophageal dissection due to eosinophilic esophagitis. A 15-year-old boy who was affected by Klinefe...

BACKGROUND Total thoracoscopic and laparoscopic esophagectomy (TLE) has attracted attention with the advantage of better operative field and minimal wound for the esophageal cancer. However, various severe complications are also reported during the TLE such as cervical anastomotic leakage, chylothorax, and tracheal injury. The aim of this study was to introduce a new optimized TLE procedure for...

Esophageal transport is a physiological process that mechanically transports an ingested food bolus from the pharynx to the stomach via the esophagus, a multilayered muscular tube. This process involves interactions between the bolus, the esophagus, and the neurally coordinated activation of the esophageal muscles. In this work, we use an immersed boundary (IB) approach to simulate peristaltic ...
