Peroral cholecystoscopy allows endoscopic access to the gallbladder via the cystic duct. This minimally invasive technique, using a small baby scope, enabled successful endoscopic lithotripsy in three patients.

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery

Background:

  • Cholecystoscopy, a technique for visualizing the gallbladder, has traditionally faced challenges related to accessing the cystic duct.
  • Developing minimally invasive methods for gallbladder examination and intervention is crucial for improving patient outcomes.

Observation:

  • Three cases of peroral cholecystoscopy were successfully performed.
  • The procedure involved dilation of the cystic duct to diameters ranging from 8.5 mm to 10.0 mm.
  • A 4.5 mm diameter baby scope was utilized, demonstrating feasibility of small-caliber instrumentation.

Findings:

  • Peroral cholecystoscopy provided adequate access to the gallbladder lumen.
  • Endoscopic lithotripsy, a treatment for gallstones, was performed without difficulty through the dilated cystic duct.

  • The technique proved effective for in-situ gallstone management.

    • Implications:

    • Peroral cholecystoscopy represents a promising alternative for gallbladder visualization and intervention.
    • This approach may reduce the need for more invasive surgical procedures for certain gallbladder conditions.
    • Further research is warranted to establish the full clinical utility and long-term safety of peroral cholecystoscopy.
