1. Effects of anesthesia on esophageal sphincters in obese patients
Sammanfattning : 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). LÄS MER
2. Effects of anasthesia on esophageal sphincters
Sammanfattning : 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.

3. Gastroesephageal reflux and related motility disorders after esophageal atresia : a clinical study
Sammanfattning : The most common congenital malformation of the esophagus is esophageal atresia (EA) with or without tracheoesophageal fistula (TEF). Successful repair of EA does not ensure normal esophageal function. Disturbed esophageal motility and gastroesophageal reflux (GER) are often detected after repair of EA. LÄS MER
4. The Columnar Lined Esophagus. Pathophysiological and Clinical Aspects
Sammanfattning : There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction.

5. Pharyngeal function, airway protection and anesthetic agents
Sammanfattning : Anesthesia related complications occur most frequently in the immediate postoperative period. The three most common conditions associated with such events are ventilatory failure, airway obstruction and aspiration. The pharynx is essential for respiration and protection of the upper airway.
