Evaluation of blood supply with indocyanine green fluorescence in resection for concurrent gastric and pancreatic cancer: A case report

Abstract

We present a rare case of concurrent resection of pancreatic and gastric cancer in which indocyanine green (ICG) fluorescence was used to evaluate the remnant stomach. An 80-year-old man was referred with a tumor in the distal pancreas. Computed tomography showed a 25-mm mass in the pancreatic tail; endoscopic ultrasound-guided fine-needle aspiration revealed adenocarcinoma. Upper gastrointestinal endoscopy and subsequent upper gastrointestinal series revealed advanced gastric cancer in the mid-stomach. Concurrent resection of the pancreatic and gastric tumors was performed. After distal pancreatectomy and distal gastrectomy, ICG evaluation of the stomach showed fluorescence extending only 3 cm distal from the cardia. To avoid ischemic change at the remnant stomach, total gastrectomy was performed. Since remnant gastric necrosis and anastomotic leak following ischemia can lead to fatal outcomes, the use of ICG to evaluate blood supply at anastomotic sites can help determine the extent of safe resection in such cases.
