A case of severe biliary stenosis after cholecystectomy and hepatoduodenal ligament lymph node dissection for early gallbladder cancer

We report a patient who developed severe biliary stenosis after undergoing cholecystectomy and hepatoduodenal ligament lymph node dissection for early gallbladder cancer. A 43-year-old man underwent cholecystectomy for gallbladder cancer, developed postoperative biliary stenosis, and again underwent surgery involving bile duct resection. The pathological diagnosis for the bile duct wall was a fibrous scar with no evidence of malignancy; therefore, the biliary stenosis was presumably secondary to disruption of the bile duct blood supply caused by lymph node dissection.
