Brief Summary

Gallstones, as a common benign gallbladder disease worldwide, have a prevalence of approximately 6.1%. Although laparoscopic cholecystectomy (LC) is currently the mainstream treatment, its associated complications cannot be overlooked, including intra-abdominal bleeding, bile leakage, intra-abdominal infection, bile duct injury, and damage to surrounding organs. With a deeper understanding of the physiological functions of the gallbladder-such as bile concentration, lipid digestion, and neuroendocrine regulation-combined with advances in minimally invasive techniques, the concept of "gallbladder-preserving stone removal" has gradually emerged. This approach aims to remove gallstones while preserving the structure and function of the gallbladder. In recent years, choledochoscopic gallbladder-preserving surgery (CGPS) has gained consensus and been incorporated into relevant guidelines. However, gallbladder-preserving stone removal still faces key controversies, particularly the balance between "preserving organ function" and the risks of "high stone recurrence" and "technical complexity." Exploring more minimally invasive and standardized procedures, optimizing patient selection, and improving postoperative management strategies are critical directions for overcoming these challenges.

    From enrollment to the end of treatment at 1year

  • Adverse events

    From enrollment to the end of treatment at 1year

  • Procedure-related parameters

    From enrollment to the end of treatment at 1year

  • Recurrence of gallstone

    From enrollment to the end of treatment at 5 year.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age: 18-80 years;
  • Sex: Both male and female;
  • Patients diagnosed with gallstones by imaging (transabdominal ultrasound, endoscopic ultrasound, CT, or MRCP), either single or multiple stones, with a maximum stone diameter ≥1 cm, gallbladder length ≥3 cm, gallbladder wall thickness \<5 mm, and with cystic duct stones or common bile duct stones excluded;
  • History of right upper abdominal pain or discomfort;
  • Gallbladder function assessment by abdominal ultrasound indicating a gallbladder ejection fraction ≥30%;
  • Willingness to preserve the gallbladder;
  • Provision of written informed consent, with understanding of the study objectives and potential risks (e.g., bile leakage, bleeding, recurrence).

You may not qualify if:

  • Patients with uncontrolled high fever or sepsis within 72 hours of acute cholecystitis onset (eligible for enrollment after inflammation is controlled);
  • Gallbladder perforation, gangrenous cholecystitis, or abscess formation;
  • Suspected or confirmed malignant gallbladder lesions;
  • Expected survival \<6 months (e.g., advanced malignancy);
  • Anatomical limitations preventing the establishment of a stable puncture tract, such as severe gastric or duodenal stenosis/deformity, severe adhesions of the gallbladder wall, obstruction by major vessels (e.g., branches of the hepatic artery or portal vein), massive ascites, or a gallbladder completely filled with stones;
  • Prior gallbladder drainage or biliary surgery (which may interfere with outcome assessment);
  • Pregnancy, coagulation disorders (PLT \<50×10⁹/L, INR \>1.5 without correction), or cardiopulmonary dysfunction rendering the patient unable to tolerate the procedure;
  • Refusal to sign informed consent.
