      Lassen, Kristoffer; Nymo, Linn Såve; Olsen, Frank; Søreide, Kjetil (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-23)
      <i>Background</i>: Length of hospital stay (LOS) may serve as a surrogate measure of healthcare quality and resource use, particularly when transfers of care and readmissions are accounted for. This study aimed to benchmark true hospital stay by measuring index, transfer and readmission stays across the range of digestive cancer surgery.<p> <p><i>Methods</i>: A cohort study of all patients ...

      Nymo, Linn Såve; Kleive, Dyre; Waardal, Kim; Bringeland, Erling Audun; Søreide, Jon Arne; Labori, Knut Jørgen; Mortensen, Kim Erlend; Søreide, Kjetil; Lassen, Kristoffer (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-07)
      <i>Background</i> - Centralization of pancreatic surgery is currently called for owing to superior outcomes in higher‐volume centres. Conversely, organizational and patient concerns speak for a moderation in centralization. Consensus on the optimal balance has not yet been reached. This observational study presents a volume–outcome analysis of a complete national cohort in a health system with ...

    • Diverting stomas reduce reoperation rates for anastomotic leak but not overall reoperation rates within 30 days after anterior rectal resection: a national cohort study 

      Myrseth, Elisabeth; Nymo, Linn Såve; Gjessing, Petter Fosse; Norderval, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-24)
      Purpose A diverting stoma is commonly formed to reduce the rate of anastomotic leak following anterior resection with anastomosis, although some studies question this strategy. The aim of this study was to assess the leak rates and overall complication burden after anterior resection with and without a diverting stoma.<p> <p>Methods A 5-year national cohort with prospectively registered data of ...

      Background Preoperative inflammatory markers were shown to be associated with prognosis following surgery for hepato-pancreato-biliary cancer. Yet little evidence exists about their role in patients with colorectal liver metastases (CRLM). This study aimed to examine the association between selected preoperative inflammatory markers and outcomes of liver resection for CRLM.<p> <p>Methods Data ...
    • The Role of Preoperative Inflammatory Markers in Pancreatectomy: a Norwegian Nationwide Cohort Study 

      Sahakyan, Mushegh; Kleive, Dyre; Dille-Amdam, Rachel G.; Kjeseth, Trond; Waardal, Kim; Edwin, Bjørn von Gohren; Nymo, Linn Såve; Lassen, Kristoffer (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-15)
      Background and purpose Preoperative infammatory markers, such as Glasgow prognostic score, modifed Glasgow prognostic score and C-reactive protein to albumin ratio, were shown to be associated with prognosis in patients undergoing pancreatectomy for cancer. However, little is known about their predictive role in a Western population.<p> <p>Methods The Norwegian National Registry for Gastrointestinal ...

      BACKGROUND: To describe the real burden of major complications after elective surgery for colon cancer in Norway, and to assess which predictors that are significantly associated with the short-term outcome. <br> <br> METHODS: An observational, multi-centre analysis of prospectively registered colon resections registered into the Norwegian Registry for Gastrointestinal Surgery, NoRGast, between ...
    • Simultaneous Resection of Primary Colorectal Cancer and Synchronous Liver Metastases: Contemporary Practice, Evidence and Knowledge Gaps 

      Kleive, Dyre; Aas, Eline; Bringeland, Erling Audun; Nesbakken, Arild; Nymo, Linn Såve; Schultz, Johannes Kurt; Søreide, Kjetil; Yaqub, Sheraz (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)
      The timing of surgical resection of synchronous liver metastases from colorectal cancer has been debated for decades. Several strategies have been proposed, but high-level evidence remains scarce. Simultaneous resection of the primary tumour and liver metastases has been described in numerous retrospective audits and meta-analyses. The potential benefits of simultaneous resections are the eradication ...

      <i>Background & aims</i> - Although malnutrition is thought to be common among patients with intraabdominal diseases and is recognized as a risk factor for postoperative complications, diagnostic criteria for malnutrition have not been consistent. Thus, the Global Leadership Initiative in Malnutrition (GLIM) has recently published new criteria for malnutrition. The aims of this study were to investigate ...
