This study highlights the value of a novel needle endoscope for interventional procedures. The minimally invasive device demonstrated safety and utility in various diagnostic and therapeutic applications.

Area of Science:

  • Minimally Invasive Surgery
  • Gastroenterology
  • Interventional Radiology

Background:

  • The needle endoscope offers a unique solution for accessing difficult-to-reach areas through standard catheter tracks.
  • Its rigid shaft (2.2 mm wide, 20 cm long) and specific illumination range (2-4 cm) are designed for precision.

Purpose of the Study:

  • To evaluate the utility and safety of a needle endoscope in various interventional procedures.
  • To describe techniques and present results from cases utilizing this specialized endoscopic instrument.

Main Methods:

  • The needle endoscope was inserted into 7-F catheter tracks for procedures.
  • Combined use with fluoroscopy for guidance in specific applications.
  • Techniques for evaluating drain tracks, fistulas, sinuses, pleura, peritoneum, gallbladder, and renal pelvis were employed.

Main Results:

  • The needle endoscope proved valuable in retracing drain tracks, evaluating fistulas/sinuses, and performing limited pleuroscopy/laparoscopy for biopsy.
  • Direct visualization of the gallbladder and renal pelvis for duct opening identification was successful.
  • Over 800 examinations were performed over 12 years with no associated morbidity.

Conclusions:

  • The needle endoscope is a safe and versatile tool for specialized interventional procedures.
  • Its ability to navigate standard catheter tracks enhances its applicability in complex diagnostic and therapeutic scenarios.
  • The instrument facilitates direct visualization for biopsies and anatomical evaluations, with a proven safety record.
