2. 1. Respiratory and esophageal morbidity in adults with repaired esophageal atresia

   Author : Vladimir Gatzinsky; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal atresia; Long-term outcome; Pulmonary function; Esophageal morbidity; Gastro-esophageal reflux; Dysphagia;

   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

4. 2. Effects of anesthesia on esophageal sphincters in obese patients

   Author : Alex de León; Magnus Wattwil; Ola Stenqvist; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lower esophageal sphincter; upper esophageal sphincter; barrier pressure; obesity; high-resolution solid-state manometry; anesthesia; MEDICINE; MEDICIN; Surgery; Kirurgi; Anaesthetics; Anestesiologi; Surgery; Kirurgi; Anaesthesiology; Anestesiologi;

   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

5. 3. Effects of anasthesia on esophageal sphincters

   Author : Rebecca Ahlstrand; Magnus Wattvil; Johan Ullman; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lower esophageal shincter; Upper esophageal sphincter; Barrier pressure; Manometry; Propofol; Remifentanil; Alfentanil; Rocuronium; Cricoid pressure; MEDICINE; MEDICIN; Surgery; Kirurgi; Anaesthetics; Anestesiologi; Anaesthesiology; Anestesiologi;

   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.

6. 4. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia

   Author : Mats Andersson; Göteborgs universitet; []
   Keywords : Achalasia; Dysphagia; Radiography; Barium esophagogram; Reproducibility of findings; Observer variation; Laparoscopic myotomy; Balloon dilatation; Esophageal neoplasms;

   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

7. 5. Experimental studies on barriers of the esophageal mucosa

   Author : Nadereh Poorkhalkali; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophagus; gastroesophageal reflux disease; glycoconjugates; lectins; esophagitis; basal cell hyperplasia; metaplasia; gastrin; cell kinetics;

   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
