What does the evidence say about gallbladder-preserving stone removal?
Clinical studies support gallbladder-preserving stone removal as an option for selected patients. They do not establish that it is generally better than cholecystectomy. Interpretation depends on the study design, patient selection, technique and duration of follow-up.
The evidence-based message is that preservation has research and clinical experience behind it and may be assessed for selected patients. Current evidence is technique- and design-dependent, so recurrence and follow-up belong in the decision.
Start with the guideline context
NICE recommends offering laparoscopic cholecystectomy for symptomatic gallbladder stones, while people with asymptomatic stones in a normal gallbladder and biliary tree generally do not need immediate treatment. This highlights the importance of symptoms and risk stratification. Support for gallbladder-preserving surgery varies across guidelines and regions; no single study replaces individual assessment.
Liu et al.: a retrospective cohort of 3,511 patients
A 2022 paper in Surgery reviewed choledochoscopic gallbladder-preserving cholecystolithotomy. Of 4,340 successful procedures, 3,511 patients (80.9%) had at least one follow-up. The authors reported 0.83% recurrence within one year and a maximum cumulative recurrence of 7.94% at 23 years. This was a single-centre retrospective case series, not a randomised trial, and it had no concurrent cholecystectomy control group. About one in five successful cases had no recorded follow-up visit. These data can inform discussion of that technique and follow-up, but cannot prove superiority or be applied to every centre or patient.
Comparative studies and meta-analyses are technique-specific
A 2020 meta-analysis and a 2022 matched NOTES study compared particular preservation techniques with laparoscopic cholecystectomy. Techniques, patient selection, study size and follow-up differ. A short-term recovery difference does not establish better long-term quality of life or overall outcomes. A matched study is not a randomised trial and does not represent all preservation procedures.
How patients can use the evidence
Ask whether the proposed technique matches the one studied, how recurrence was defined, how many patients completed follow-up, what monitoring is needed, how recurrence would be managed, and which patients the results describe. If only success stories or a single recurrence percentage are presented, ask for the denominator, losses to follow-up and comparison group.
A practical conclusion
Studies document clinical experience worth discussing and further research, while also showing the need for long-term follow-up. They do not justify saying that preservation suits everyone or is generally superior to cholecystectomy. For selected patients, it can be discussed as one shared-decision option after uncertainties and alternatives are explained.
