Morison Pit
The Morison Pit (Morison bag, Morison's pouch, Morison pouch, recess mori soni, hepatorenal recess, falsely often Mor r ison Pouch u. Ä.) Is a intraperitoneally situated room. Its back wall is formed by the right kidney , located retroperitoneally , and its front by the back wall of the right lobe of the liver .
The Morison Pit is named after the British surgeon James Rutherford Morison (1853–1939).
This space is of particular importance in ultrasound diagnostics : in the case of a person lying on their back, this space is the deepest in the abdominal cavity, so that fluids (e.g. blood if internal organs are injured or ascites in diseases of the liver) accumulate there and can also be recognized by the inexperienced user of the ultrasound. The presence of fluid (“free fluid”) in this space or in the Douglas space (in female patients) or in the rectovesical cavity (in male patients) usually leads to a change in therapy for a multiple injured person , since life the injured person is much more threatened by an internal injury (for example a ruptured spleen ) than by an injury to the extremities .
An accumulation of liquid on the left side is sought in the Koller pouch .
