Insights
A gallbladder tumor caused severe anemia and black stools in a patient on anticoagulant medication. Laparoscopic cholecystectomy was performed, revealing papillary adenocarcinoma.
Area of Science:
- Gastroenterology
- Surgical Oncology
Background:
- A 77-year-old woman on anticoagulant therapy presented with symptoms suggestive of gastrointestinal bleeding.
- Initial investigations revealed a gallbladder tumor as a potential source of hemorrhage.
Abstract:
A 77-year-old woman was taking anticoagulant medication for pulmonary hypertension. Black stools were noted in August 2018. Close abdominal ultrasonography revealed a broad-based tumor at the base of the gallbladder. Lower endoscopy showed no obvious digestive tract hemorrhage but hemorrhage from a gallbladder tumor was suspected. The resected procedure was suspected for gallbladder cancer(cT2N0M0, cStageⅡ), but dizziness 5 days before operation. The patient complained of severe anemia, and underwent laparoscopic cholecystectomy for hemorrhage control. In the macroscopic examination of the specimens, tumorous lesions and blood clots were found adhered to the bottom of the gallbladder. The histopathological diagnosis was papillary adenocarcinoma.
