Percutaneous transhepatic cholecystoscopy aids early gallbladder cancer diagnosis and offers a nonsurgical treatment for gallstones. This minimally invasive technique provides reliable histological diagnosis and effective stone removal.

Area of Science:

  • Gastroenterology and Hepatology
  • Minimally Invasive Procedures
  • Diagnostic Endoscopy

Background:

  • Gallbladder diseases, including carcinoma and cholecystolithiasis, pose significant health challenges.
  • Accurate and early diagnosis of gallbladder carcinoma is crucial for effective treatment.
  • Nonsurgical treatment options for gallstones are continually being explored.

Purpose of the Study:

  • To evaluate the efficacy of percutaneous transhepatic cholecystoscopy for diagnosing gallbladder diseases, particularly early-stage gallbladder carcinoma.
  • To assess the utility of this method for differential diagnosis between malignant lesions and benign polyps.
  • To report on the application of endoscopic lithotripsy as a nonsurgical treatment for cholecystolithiasis.

Main Methods:

Related Experiment Videos

  • Percutaneous transhepatic cholecystoscopy was performed through the sinus tract of percutaneous cholecystostomy in 72 patients.
  • Histological diagnosis was achieved via cholecystoscopic biopsies in patients with suspected gallbladder carcinoma.
  • Endoscopic lithotripsy using Nd:YAG laser or electrohydraulic lithotripter was employed for cholecystolithiasis treatment.

    • Main Results:

    • Histological diagnosis was successful in all 21 patients with gallbladder carcinoma, including eight early-stage cases.
    • The method reliably differentiated between carcinoma and polypoid lesions and identified cancer extension to the cystic duct.
    • Twenty-one patients with cholecystolithiasis were successfully treated with endoscopic lithotripsy.

    Conclusions:

    • Percutaneous transhepatic cholecystoscopy is a valuable tool for the early diagnosis of gallbladder carcinoma, offering definitive histological assessment.
    • This technique is recommended as a definitive diagnostic step for early gallbladder cancer detection and staging.
    • Endoscopic lithotripsy presents a viable nonsurgical treatment option for patients with cholecystolithiasis.
