A 77-year-old man was diagnosed with gastric cancer and underwent robot-assisted total gastrectomy, D2 lymph node dissection, and Roux-en Y reconstruction. The histopathological diagnosis was pT4a (SE)N3aM0 Stage IIIB. CEA showed a temporary increase after three courses, but postoperative adjuvant chemotherapy with S-1 was ended without recurrence, with this decision made based on normal tumor markers and CT. Acute cholangitis and gallbladder stones were observed 26 months after gastrectomy, and thus, laparoscopic cholecystectomy was performed following conservative treatment. There were no specific findings in the gallbladder in preoperative CT or intraoperatively, but postoperative histopathological diagnosis revealed that the gallbladder had many nodules of metastatic gastric cancer. Thus, this case is a rare example of gallbladder metastasis of gastric cancer.
