Usefulness of indocyanine green fluorescence imaging: A case of laparoscopic distal gastrectomy after distal pancreatectomy with splenectomy.

Safe preservation of the remnant stomach during distal gastrectomy in patients who have undergone distal pancreatectomy is important. During distal pancreatectomy, the splenic artery that supplies arterial blood to the cardiac part of stomach is resected. Previous reports suggested that blood flow to the remnant stomach may be insufficient when supplied by only the left inferior phrenic artery. In the present case, a 79-year-old woman who underwent distal pancreatectomy with splenectomy 20 years before she was diagnosed with gastric cancer and referred to our hospital. We performed laparoscopic distal gastrectomy and Roux-en-Y reconstruction because preoperative CT scan indicated a developed left inferior phrenic artery. To evaluate the blood supply, we employed indocyanine green fluorescence and were able to safely preserve the remnant stomach. Our experience suggests that indocyanine green fluorescence is potentially useful for evaluating blood flow to the remnant stomach.
