1. Respiratory and esophageal morbidity in adults with repaired esophageal atresia
Abstract : Background: Esophageal atresia (EA) often leads to persistent esophageal and respiratory symptoms, as well as impaired esophageal and lung function in adulthood. The reasons for this, and the connections between symptoms and documented abnormalities, are not fully understood. READ MORE

2. Effects of anesthesia on esophageal sphincters in obese patients
Abstract : The lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) play a central role in preventing regurgitation and aspiration. The aim of this thesis was to evaluate the UES, LES, esophageal (E) and barrier (Br) pressures (P) using high resolution solid state manometry (HRSM). READ MORE

3. Effects of anasthesia on esophageal sphincters
Abstract : The esophageal sphincters constitute the anatomical protection against pulmonary aspiration. The aim of this thesis was to study the esophageal sphincters and how they are affected by different components of emergency anesthesia using high-resolution solid-state manometry.The effect of propofol (0.

4. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia
Abstract : In idiopathic achalasia, degeneration of the inhibitory innervation of the esophageal smooth muscle results in absence of primary peristalsis and in incomplete relaxation of the lower esophageal sphincter (LES). All treatments for achalasia aim at reducing the pressure gradient across the LES, thus facilitating esophageal emptying by gravity. READ MORE

5. Experimental studies on barriers of the esophageal mucosa
Abstract : Reflux esophagitis is the multifactorial result of the failing of protective barriers and the aggressive assault on the esophageal epithelium by gastric contents entering the esophagus. The three main lines of defense against reflux are: the antireflux barriers, the luminal acid clearance and the epithelium itself. READ MORE
