    • Diagnostic accuracy of transabdominal ultrasound in chronic pancreatitis 

      Engjom, Trond; Sangnes, Dag André; Havre, Roald Flesland; Erchinger, Friedemann Georg; Pham, Khanh Do-Cong; Haldorsen, Ingfrid S.; Gilja, Odd Helge; Dimcevski, Georg Gjorgji (Peer reviewed; Journal article, 2017-04)
      The performance of transabdominal ultrasound (US) in chronic pancreatitis (CP) following the advances in US technology made during recent decades has not been explored. Our aim in this prospective study was to evaluate the ...

    • Effects of high intake of cod or salmon on gut microbiota profile, faecal output and serum concentrations of lipids and bile acids in overweight adults: a randomised clinical trial 

      Bratlie, Marianne; Hagen, Ingrid Valheim; Helland, Anita; Erchinger, Friedemann Georg; Midttun, Øivind; Ueland, Per Magne; Rosenlund, Grethe; Sveier, Harald; Mellgren, Gunnar; Hausken, Trygve; Gudbrandsen, Oddrun Anita (Journal article; Peer reviewed, 2020-10-27)
      Purpose To explore whether high intake of cod or salmon would affect gut microbiota profile, faecal output and serum concentrations of lipids and bile acids. Methods Seventy-six adults with overweight/obesity with no ...

      Erchinger, Friedemann Georg; Engjom, Trond; Dimcevski, Georg Gjorgji; Drewes, Asbjørn M.; Olesen, Søren Schou; Vujasinovic, Miroslav; Löhr, Johannes-Matthias; Nøjgaard, Camilla; Novovic, Srdan; Laukkarinen, Johanna; Parhiala, Mikael; Björn, Lindkvist; Waage, Anne; Hauge, Truls; Pukitis, Aldis; Ozola-Zalite, Imanta; Kalaitzakis, Evangelos; Okhlobystin, Alexey; Barauskas, Giederius; Efsen, Dahl Eva; Tjora, Erling (Journal article; Peer reviewed, 2022)
      Background/objectives There is scarce information about risk factors for exocrine pancreas insufficiency (EPI) in chronic pancreatitis (CP), and how it associates with other complications. The aim of the present study was ...

    • Fecal fat analyses in chronic pancreatitis importance of fat ingestion before stool collection 

      Erchinger, Friedemann Georg; Engjom, Trond; Jurmy, Palwasha; Tjora, Erling; Gilja, Odd Helge; Dimcevski, Georg Gjorgji (Peer reviewed; Journal article, 2017-01-17)
