Transgastroscopic ultrasonography.

H Lutz, W Rösch

    Endoscopy
    |November 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    A new endoscopic ultrasound probe aids in distinguishing solid from cystic masses in the upper abdomen. This technology enables guided puncture of pancreatic pseudocysts via the gastric lumen, preventing complications.

    Area of Science:

    • Gastroenterology
    • Medical Imaging
    • Surgical Innovation

    Background:

    • Upper abdominal masses require accurate differentiation between solid and cystic types.
    • Pancreatic pseudocysts pose a risk of pancreato-cutaneous fistula formation if improperly managed.
    • Endoscopic access to the upper abdomen is established for diagnostic and therapeutic interventions.

    Purpose of the Study:

    • To introduce a novel ultrasonography probe designed for endoscopic use.
    • To evaluate the probe's capability in differentiating upper abdominal masses.
    • To assess the feasibility of guided pseudocyst puncture via the gastric lumen.

    Main Methods:

    • A new ultrasonography probe was developed for insertion into an operative endoscope's instrumentation channel.

  • The A-scan feature of the probe was utilized to analyze upper abdominal masses.
  • Image guidance was employed for transgastric puncture of diagnosed pancreatic pseudocysts.

    • Main Results:

    • The ultrasonography probe successfully differentiated between solid and cystic masses.
    • Gastric impression was achieved for masses requiring intervention.
    • Guided puncture of pancreatic pseudocysts from the gastric lumen was demonstrated as feasible.

    Conclusions:

    • The novel endoscopic ultrasonography probe is effective for mass characterization in the upper abdomen.
    • Transgastric puncture of pancreatic pseudocysts is a viable and safe therapeutic approach.
    • This technique minimizes the risk of developing pancreato-cutaneous fistulas.
