Abstract

A 51-year-old man was referred to our clinic for recurrent obstructive jaundice and underwent pylorus-preserving pancreaticoduodenectomy for a suspected malignancy. The pathology showed immunoglobulin G4 positive plasma cell infiltrated at the pancreas and the gallbladder. We discuss the cost-effectiveness of serum immunoglobulin G4 level prior to arranging for a pancreaticoduodenectomy, which would reduce the possibility of surgical complications as well as costs.
