Abstract
An 81-year-old woman was diagnosed with a gall bladder tumor that was increasing in size during the follow-up for chronic non-specific enterocolitis. Surgery for suspected gallbladder cancer was scheduled. Although invasion into the liver was not obvious, we suspected that tumor invasion extended beyond the muscularis propria. Because the patient's general condition was not satisfactory, given her advanced age, we decided to opt for minimally invasive surgery. Therefore, laparoscopic cholecystectomy and radiofrequency ablation of the liver bed was performed. On pathology, adenoendocrine cell carcinoma of the gallbladder was diagnosed. The postoperative course was uneventful. Currently, at 4 years 3 month after surgery, the patient is alive without recurrence. Adenoendocrine cell carcinoma of the gallbladder is rare and is associated with poor prognosis. Few cases of long-term survival have been reported. A literature review did not identify any report on radiofrequency ablation of the liver bed for gallbladder cancer. Here, we describe the clinical features of this disease and show that radiofrequency ablation is a possible treatment option for gallbladder cancer.
