  1. 21. Technical Aspects of Laparoscopic Liver Resection. An Experimental Study

    Författare :Kristinn Eiriksson; Dag Arvidsson; Sten Rubertsson; Bjørn Edwin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas embolism; laparoscopy; liver resection; pneumoperitoneum; carbon dioxide; argon; bleeding; stapling device;

    Sammanfattning : Various techniques are used to transect the liver. With increase in laparoscopic liver resections (LLR), it is of even more interest to develop surgical techniques to minimize bleeding and the risk for gas embolism during transection. Instrument like argon enhanced coagulator provides good hemostasis but increases the danger of gas embolism. LÄS MER

  3. 22. Gastric Bypass : Facilitating the Procedure and Long-term Results

    Författare :David Edholm; Magnus Sundbom; Per Hellman; Anders Thorell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morbid obesity; Gastric bypass; Laparoscopy; Low-calorie diet; Magnetic resonance imaging; Magnetic resonance spectroscopy; Kirurgi; Surgery;

    Sammanfattning : Gastric bypass achieves weight loss in the morbidly obese. Preoperative weight loss is used to reduce the enlarged fatty liver that otherwise reduces visibility during surgery. The purpose of gastric bypass is to provide patients with long-term weight loss. LÄS MER

  4. 23. Hepatic and Peritoneal Colorectal Metastases : Aspects of Prognosis and Treatment

    Författare :Haile Mahteme; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Colorectal cancer; lever metastas; peritoneal metastas; intraperitoneal; tumör reduktion; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Although two-thirds of colorectal cancer patients are cured by surgery, approximately 50% of the patients with this disease develop locally recurrent or distant metastases during the course of their illness. The aim of this study was to identify metastatic sites associated with poor prognosis in rectal cancer and then to investigate methods that can prevent the development and growth of metastases and optimise uptake of drugs at these sites in animal models.

  5. 24. Surgical Aspects and Prognostic Factors in the Management of Rectal Cancer

    Författare :Kevin Afshari; Maziar Nikberg; Kennet Smedh; Abbas Chabok; Per J. Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Loop ileostomy; Small bowel obstruction; Defecatory dysfunction; Stage IV rectal cancer; Surgery; Kirurgi;

    Sammanfattning : Survival among patients with stage IV rectal cancer is poor and surgical treatment for this disease is associated with morbidities such as small bowel obstruction, complications with a diverting loop ileostomy, and functional bowel disturbances. The overall aim of this thesis was to assess risk factors and morbidity after surgery for rectal cancer and to evaluate factors affecting survival in patients with stage IV rectal cancer. LÄS MER

  7. 25. Prognostic Factors for Death in Small Intestinal Neuroendocrine Tumours

    Författare :John Eriksson; Per Hellman; Kjetil Søreide; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; SI-NET; Prognostication; Immunohistochemistry; Surgery; Kirurgi;

    Sammanfattning : Tumours in the small intestine are rare compared to those in other gastrointestinal organs. Small intestinal neuroendocrine tumours (SI-NETs) are the most common small bowel tumours with an annual incidence of 0.3-1.7 per 100 000 persons. LÄS MER
