  1. 21. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia

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

    Sammanfattning : 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. LÄS MER

  3. 22. Antireflux surgery in the prevention of supra-esophageal cancer and mortality

    Författare :Manar Yanes; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Gastroesophageal reflux disease (GERD), mainly characterized by heartburn or regurgitation, is a common condition in the Western world with an increasing prevalence. GERD is associated with an increased risk of adenocarcinoma of the esophagus, and possibly of supraesophageal cancers of the larynx, pharynx and lung. LÄS MER

  4. 23. Aspects of gastroesophageal reflux and risk for esophageal cancer : an epidemiological approach

    Författare :Weimin Ye; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Gastroesophageal reflux; anti-reflux surgery; esophagus; adenocarcinoma; squamous- cell carcinoma; H. pylori; gastric atrophy; DNA repair gene; polymorphism; cohort study; case-control study; relative risk;

    Sammanfattning : Aims: The aims of this study were to confirm, in a prospective study, the link between gastroesophageal reflux. and risk of adenocarcinoma of the esophagus and gastroesophageal junction observed in retrospective studies, to investigate into the effects of anti-reflux surgery, and to shed light on some possible mechanisms behind the alleged carcinogenicity.

  5. 24. Risk indicators for esophageal cancer : some medical conditions and tobacco-related indicators

    Författare :Kazem Zendehdel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Because of little progress in the prognosis and survival of esophageal cancer patients, the early diagnosis and prevention have been prioritized. Alcohol consumption and tobacco smoking are the main risk factors of squamous cell carcinoma, and high body mass index and gastroesophageal reflux are strongly linked to adenocarcinoma of the esophagus.

  7. 25. Liver cirrhosis : epidemiology, prognosis, and cancer

    Författare :Bonnie Bengtsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Liver cirrhosis is a major risk factor for hepatocellular carcinoma (HCC). Patients with liver cirrhosis also have a high risk to develop infections leading to deterioration of liver function and increased mortality. LÄS MER
