A 68-year-old man who had undergone distal gastrectomy for gastric cancer 3 years previously, presented to our hospital for examination of dilatation of the main pancreatic duct on follow-up computed tomography and magnetic resonance cholangiopancreatography. After examination, he was diagnosed with early-stage pancreatic cancer and distal pancreatectomy (DP) was planned. With informed consent, we performed indocyanine green (ICG) fluorography during DP and digital subtraction angiography (DSA) of vessels supplying the remnant stomach immediately before and after DP. On ICG fluorography, the remnant stomach gradually became fluoresced starting at the area of the lesser curvature, and the fluorescence eventually intensified over the entire area of the remnant stomach to the same brightness as that of the liver and duodenum. On DSA following DP, the terminal branches of the left inferior phrenic artery (LIPA) were distributed to more than half of the area of the remnant stomach, centering around the proximal area. It is useful to confirm blood flows to the remnant stomach by ICG fluorography using a near-infrared imaging camera during DP. We found that the LIPA played an important role in maintaining the blood supply to the remnant stomach in the absence of the left gastric artery and splenic artery.© 2021.
