NCT01234714

Brief Summary

The purpose of this study is to objectively quantify liver fat content (LFC) by Magnetic Resonant Imaging (MRI) prior to major liver surgery, and to investigate its association with post-operative complications.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Liver Fat Content on MRI in Patients With Serious Post-operative Complications (Clavien-Dindo Grade ≥IV)

    Liver fat content, measured by MRI, uses the in-phase/out-of-phase imaging calculated in terms of fat signal fraction (FSF). The Clavien-Dindo Classification of Surgical Complications: Grade I: Any deviation from the normal postoperative course without the need for treatment. Grade II: Requiring pharmacological treatment with drugs. Grade III: Requiring surgical, endoscopic or radiological intervention. Grade IV: Life-threatening complication requiring IC/ICU-management. Grade V: Death of a patient

Secondary Outcomes (7)

  • Post-operative Alanine Transaminase (ALT) Levels

    December 2010

  • Intra-operative Blood Loss

Study Arms (1)

Major liver resection

This single Cohort/Group will include all consecutive patients that received pre-operative Magnetic Resonant Imaging (MRI) and underwent major liver resection (\>=3 segments).

Other: Non-invasive Magnetic Resonance Imaging (MRI)Procedure: Major liver resection

Interventions

Conventional pre-operative MRI

Also known as: Magnetic Resonance Imaging
Major liver resection

Hepatectomy of \>= 3 liver segments

Also known as: Hepatectomy = liver resection by open surgery.
Major liver resection

Study Population

Primary care clinics

You may qualify if:

  • Major liver resection (\>= 3 resected segments).
  • Patients that received a pre-operative Magnetic Resonance Imaging (MRI).
  • Patient over 18 years of age

You may not qualify if:

  • Patients that underwent liver surgery but \< 3 segments were resected (e.g. wedge liver resection).
  • Patient that did not receive a pre-operative MRI
  • Patient age less than 18 years of age.
