[A Case of Synchronous Gallbladder Metastasis Originating from Advanced Gastric Cancer].

Gallbladder metastasis from gastric cancer is often found accidentally during postoperative pathological examinations, and its preoperative diagnosis is very difficult. There are a few reports in diagnostic imaging, and it is well known to have a very poor prognosis. There have been 13 reports on gallbladder metastasis from gastric cancer in the Japanese literature. Among the 13 reports, 10 cases were diagnosed with gallbladder metastasis synchronously and only 1 case was diagnosed as gallbladder metastasis before surgery. One case was reported as hematogenous metastasis, and 9 cases were reported as lymphoid metastasis. In total, 7 patients died, all within the first year after surgery. We experienced a case of synchronous gallbladder metastasis from gastric cancer.
