[Synchronous Resection of Gallbladder Hyperplasia Polyps with Pancreaticobiliary Maljunction without Dilation of the Bile Duct and Sigmoid Colon Carcinoma].

We report synchronous resection of gallbladder hyperplasia polyps with pancreaticobiliary maljunction without dilation of the bile duct and sigmoid colon carcinoma. The patient was a 60-year-old woman diagnosed with sigmoid colon cancer. Gallbladder polyps were detected incidentally during a preoperative examination for sigmoid colon cancer that was discovered because of anemia. Detailed examination revealed a suspected gallbladder carcinoma along with pancreaticobiliary maljunction without dilation of the bile duct. The patient underwent synchronous open colectomy and cholecystectomy. Histopathological diagnosis excluded gallbladder carcinoma, so we did not perform bile duct resection or lymph node resection around the bile duct. The final diagnosis was gallbladder hyperplasia polyps, chronic cholecystitis, and sigmoid colon cancer (pT3N2M0, stage Ⅲb). Therefore, physicians should pay attention to the possibility of pancreaticobiliary maljunction if gallbladder polyps are detected incidentally during preoperative examination for other diseases. In the present case, we could treat the patient with minimally invasive techniques by adding the treatment to that performed for the other disease.
