Gallbladder cancer is a rare cancer, associated with an extremely poor prognosis. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is not commonly performed in gallbladder cancer; however, case series have shown prolonged survival time with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in gallbladder cancer and no increase in morbidity compared to cytoreductive surgery without hyperthermic intraperitoneal chemotherapy. We present a case of gallbladder cancer with peritoneal metastases in a 60-year-old male who was successfully treated with complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and survived for 4 years following diagnosis.
