   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Colonoscopy; population-based; indications; completion rates; complications; colorectal cancer; sensitivity; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : In a population-based study in the county of Södermanland, 6066 colonoscopies performed in 4304 patients from 1979 to 1995 inclusive were evaluated. As indications, bleeding increased and polyps and unclear x-ray findings decreased. Surveillance (cancer, polyps, colitis) was fairly stable. LÄS MER

3. 2. Going trough a colonoscopy and living with inflammatory bowel disease : children's and parents' experiences and evaluation of the bowel cleansing quality prior to colonoscopy

   Författare :Vedrana Vejzovic; Malmö högskola; []
   Nyckelord :Colonoscopy; Inflammatory bowel diseases; Randomised control trial; Content analysis; Phenomenological hermeneutics;

   Sammanfattning : This thesis focuses on children aged 10-18 years with symptoms of, ordiagnosed with, inflammatory bowel disease (henceforth referred to as IBD).Before the disease can be diagnosed, a child must undergo several procedures,with colonoscopy as an established investigation, including bowel cleansing,which is crucial for the safe examination of the intestine.

   Sammanfattning : BackgroundGastrointestinal (GI) symptoms are commonly reported in a normal population. Mostly, the symptoms are of benign cause but occasionally the symptoms can be signs of a more harmful disease. In general, it is difficult to distinguish whether the reported symptoms are caused by a benign (functional) or organic (i.e. LÄS MER

7. 5. CT Colonography: implementation and technical developments

   Författare :Valeria A Fisichella; Göteborgs universitet; []
   Nyckelord :X-ray Computed Tomography; Computed Tomographic Colonography; Computer-Assisted Image Processing; Three-Dimensional Imaging; Colonoscopy; Colon; Rectum; Colorectal Neoplasms; Computer-Assisted Diagnosis; Ionizing Radiation;

   Sammanfattning : Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care.
