Extreme discrepancy between macroscopic diagnosis and pathological findings of gallbladder cancer treated by hepatopancreatoduodenectomy.
Diagnosis of gallbladder cancer in terms of invasion depth and spread is an important factor in determining cumulative survival after surgical treatment. However, diagnostic methods available at present occasionally fail to judge staging correctly. We report a case of gallbladder cancer which showed extreme discrepancy between the preoperative macroscopic and imaging diagnosis (positive direct invasion to the liver and invasion to the bile duct and duodenum through the serosal layer; S3, Hinf3, Binf2, and stage IV by the Japanese Society of Biliary Surgery classification) and the pathological findings (limited in vasion within the subserosal layer; ss, hinf0. binf0, and stage II). This discrepancy allowed us to perform curative treatment by hepatopancreatoduodenectomy, including extended right lobectomy of the liver, external bile duct resection, resection of the mesocolon, and lymph node dissection. Surgeons should aim for curability of advanced gallbladder cancer by radical resection until accurate methods for the preoperative diagnosis of cancer spread are available, because the clinical picture may be modified by inflammatory changes.
