Should debulking surgery be performed for a ruptured gallbladder carcinoma, or is palliation with chemotherapy (gemcitabine plus cisplatin), biliary stenting, and drainage the appropriate management?

Management of Ruptured Gallbladder Carcinoma

Debulking surgery should not be performed for ruptured gallbladder carcinoma; instead, proceed with palliative biliary drainage, systemic chemotherapy with gemcitabine plus cisplatin, and best supportive care. Rupture represents advanced, unresectable disease where surgical intervention increases morbidity without improving survival outcomes.

Why Surgery is Contraindicated in Ruptured Disease

Gallbladder rupture indicates peritoneal contamination and represents stage IV disease with peritoneal metastases, which is definitively unresectable. 1, 2

• Peritoneal metastases are present in 10-20% of gallbladder cancer patients at diagnosis and represent a contraindication to curative resection 2
• Surgery should not be performed when disease resectability has not been established, nor should it be performed by surgeons untrained in hepatobiliary oncology 1
• The NCCN explicitly advises against delaying chemotherapy while pursuing multiple surgical opinions in metastatic disease 3

Appropriate Palliative Management Algorithm

Step 1: Establish Biliary Drainage First

Biliary drainage via ERCP with stent placement should be performed before initiating chemotherapy if technically feasible, as it improves both survival and quality of life. 1, 3, 4

• Metal stents are preferred over plastic stents if life expectancy exceeds 6 months, as cost analysis demonstrates superior patency and cost-effectiveness 1, 3, 4
• Biliary drainage followed by chemotherapy results in improved quality of life compared to chemotherapy alone 1
• Percutaneous transhepatic cholangiography (PTC) should be available as an alternative when ERCP fails 4

Step 2: Initiate Systemic Chemotherapy Immediately

Start gemcitabine plus cisplatin chemotherapy immediately after performance status assessment (Karnofsky ≥50) and biliary drainage, as this provides a 4-month survival benefit over best supportive care alone. 3

• The standard regimen is gemcitabine 1000 mg/m² on days 1 and 8 plus cisplatin 25-70 mg/m² on day 1, repeated every 21 days 5, 6
• Disease control rates reach 59.5-64% with this combination, including complete and partial responses 5, 6
• Median overall survival is 8-10 months with treatment versus 5.8 months without treatment 3, 6
• Do not delay chemotherapy initiation in patients with adequate performance status 3

Step 3: Monitor for Complications

Patients with biliary stents require close monitoring for recurrent sepsis, biliary obstruction, and stent occlusion, which are common causes of death in addition to disease progression. 3, 4

• Metal stent occlusion may cause complex biliary obstruction and sepsis requiring restenting 4
• Tumor growth through mesh metal stents can be managed by inserting plastic stents through the metal stent lumen 1

Prognostic Factors to Consider

Quality of life should be the primary focus with survival as a secondary endpoint in stage IV disease management. 3

• Median survival without treatment is approximately 5.8 months, with 5-year survival of only 1% 3
• Negative prognostic factors include liver metastases (HR 1.63), neutrophil-to-lymphocyte ratio ≥3 (HR 1.65), CEA ≥5 ng/mL (HR 1.50), and CA19-9 ≥500 U/mL (HR 1.59) 6
• Achieving stable disease has value that translates into both length and quality of life 3

Critical Pitfalls to Avoid

Never attempt debulking surgery in ruptured gallbladder cancer, as this represents peritoneal dissemination and unresectable disease. 1, 2

• Do not use plastic stents when life expectancy exceeds 6 months—metal stents have superior patency 1, 3, 4
• Do not wait for disease progression before initiating chemotherapy in patients with adequate performance status 3
• Do not neglect biliary drainage in symptomatic obstruction, as this worsens quality of life and prevents effective chemotherapy delivery 1, 3
• Avoid routine surgical bypass, as endoscopic stenting has equivalent outcomes with lower morbidity 4
