Abstract
IntroductionThe incidence of de novo malignancies after organ transplantation is increasing. We herein report a patient who developed gastric cancer after living donor liver transplantation (LDLT) and splenectomy. Intraoperative indocyanine green (ICG) fluorescence angiography immediately after gastrectomy was useful for evaluating the blood supply into the remnant stomach in this patient. Presentation of caseA 69-year-old woman underwent LDLT and splenectomy for end-stage liver disease. Gastric cancer was found by an endoscopic examination eight years after LDLT. Although total gastrectomy was considered due to previous splenectomy, we decided to intraoperatively evaluate the flow of the remnant stomach using ICG fluorescence. After ligation of the left gastric artery and transection of the stomach with a sufficient proximal margin from the tumor, intraoperative ICG fluorescence angiography showed abundant intramural blood flow of the remnant stomach. We were able to preserve the proximal stomach with confidence and she recovered smoothly after the operation without any signs of acute rejection. ConclusionIntraoperative ICG fluorescence angiography may be helpful for evaluating the blood flow in the remnant stomach during surgery for de novo gastric cancer after LDLT.
