Abstract
A 78-year-old woman was admitted to our hospital because of an abdominal pain. It was pointed out the focal wall thickening of gall bladder by ultrasonography (US). In the US, endoscopic ultrasonography (EUS) and abdomen CT, the qualitative diagnosis was difficult, but, by endoscopic double contrast cholecystography, we defected the irregular membrane of the gallbladder that normal reticular pattern disappeared, granular pattern fused and it was drawn to the center. We diagnosed it as IIb-type early stage gallbladder cancer and cholecystectomy was carried out. The pathology diagnosis was IIb-liked advanced gallbladder cancer, ss, well-differenciated tubular adenocarcinoma, ly0, v0, pn0, n0. The range was defected by endoscopic double contrast cholecystography approximately precisely agreed with the change of IIb menbrane. It was thought that gallbladder cancer had difficulty with a preoperative diagnosis conventionally for the non-elevated type, but it was thought that the cancer was able to be detected by doing the endoscopic double contrast cholecystography, even if it was non-elevated-type gallbladder cancer.
