Whether the remnant stomach can be safely preserved when performing distal pancreatectomy (DP) in patients with a prior distal gastrectomy (DG) remains unclear because the remnant stomach and pancreatic body/tail share an arterial blood supply via the splenic artery (SPA). A total of 18 patients with prior DG who underwent DP were enrolled in this study. Clinicopathologic data were retrospectively analyzed with a focus on management of the remnant stomach and complications related to ischemia of the remnant stomach. Additionally, intraoperative indocyanine green (ICG) fluorescence angiography was performed to visualize the blood flow and circulation in the remnant stomach. Ten patients underwent a standard DP (DP in conjunction with splenectomy and division of the SPA) with preservation of the remnant stomach. The entire stomach was preserved in seven patients, and three underwent concomitant partial resection of the remnant stomach. No patients in whom the entire remnant stomach was preserved developed postoperative complications associated with it, whereas two of the three patients who underwent partial resection of the remnant stomach developed severe ischemic complications. Intraoperative ICG fluorescence angiography revealed a caudally directed circulation of blood from the esophagogastric junction through the intramural capillary network in the remnant stomach. When performing DP in patients with a prior DG, preservation of the entire remnant stomach was a safe procedure because of the presence of an intramural network that supplies blood to the remnant stomach. In contrast, partial resection of the remnant stomach could be dangerous because of the potential for severe ischemic complications.
