Cholecystoduodenal fistula in a patient post-Roux-en-Y gastric bypass.

We presented a case of a cholecystoduodenal fistula in a patient 4 years post-Roux-en-Y gastric bypass. The patient presented with biliary colic symptoms after a stone became impacted in the fistula and outflow through the cystic duct was intermittently obstructed by a second stone. The fistulous tract was taken down with a cholecystectomy and duodenum repaired with a modified Graham patch.
