Experimental and Molecular Pathology – Focus HPB and GI Pathology

Experimental and Molecular Pathology – Focus: Molecular Hepatobiliary and Gastrointestinal Pathology, Group Achim Weber.

The University Hospital Zurich (USZ) has a major focus on diseases of the hepato-pancreato-biliary system and gastro-intestinal tract. The Swiss Hepato-Pancreato-Biliary (HPB) center and the ENTES (European neuroendocrine tumor society) center both are centers of excellence in Zurich for diseases of the liver, biliary tract and pancreas, and gastro-entero-pancreatic neuroendocrine (GEP-NET), respectively. A professorship was implemented in 2010 to cover the need of the University of Zurich (UZH) and the USZ in research and diagnostics in the field of liver, biliary tract, pancreas, and gastrointestinal pathology.

Clinical pathology, diagnostic team and diagnostic profile

Diagnostic Profile

The team covers the whole spectrum of diagnostic pathology in the field of liver, biliary tract, pancreas, and gastrointestinal pathology. A major focus is on diagnostic molecular pathology. Besides routine diagnostic cases, these fields comprise highly specialized works and activities, such as:

  • Surgical pathology and molecular testing of cases within the Swiss Hepato-Pancreato-Biliary (HPB) center
  • Surgical pathology of neuroendocrine tumors (NET Board)
  • Molecular diagnostic of hereditary cancer syndromes including genetic testing (MEN1, MEN2, SDH, VHL)
  • Second opinion and outside consultant cases in these fields

Surgical pathology service is performed in close interaction with clinical partners within the USZ and outside. The following clinical conferences are held on a regular basis:

  1. Surgical-oncological (HPB) board (weekly)
  2. Surgical-oncological (GIT) board (weekly)
  3. Hepato-pathological conference (weekly)
  4. NET board (biweekly)
  5. Gastro-intestinal conferences (gastrointestinal clinics: USZ, Stadtspital Waid, Zürich, Spital Männedorf, GCZ – Gastro Club Zurich)
