Incidental Gallbladder Carcinoma (T1b) After Cholecystectomy: Next Step When Surgical Re-operation Does Not Achieve Tumour-Free Margins
This protocol addresses patients with a history of cholecystectomy in whom gallbladder carcinoma (stage T1b, no metastatic spread) was discovered incidentally — and who have already undergone surgical re-operation with radical intent.
Clinical scenario
Gallbladder carcinoma incidentally diagnosed after cholecystectomy, staged at T1b with no evidence of metastatic spread. The history of cholecystectomy is the defining clinical context for both diagnosis and subsequent management decisions.
When the prior surgical step falls short
The previous treatment step — re-operation with radical intent (resection of hepatic segments and lymphadenectomy of the hepatoduodenal ligament) — aimed to achieve R0 resection with no tumour at the margin. This protocol represents the structured next step taken when that primary surgical goal is not met.
Next step (partial overview)
Adjuvant chemotherapy is considered as the subsequent approach following surgical management. The complete regimen — including agent selection, cycle details, sequencing, and full clinical criteria — is available in the structured protocol below.

- In case of incidentally diagnosed GBC (after cholecystectomy), re-operation with radical intent should be offered to sufficiently fit patients with stage T1b disease, provided there is no metastatic spread.
- Adjuvant ChT with capecitabine should be considered for patients with CCA or GBC following resection.
- median OS was significantly improved with eight 3-weekly cycles of capecitabine compared with observation
