Laparoscopic Total Devascularization of the Upper Stomach and Splenectomy (Hassab's Procedure) Under Indocyanine...

The use of surgical treatment for refractory isolated gastric varices has decreased owing to the development of endoscopic and radiologic procedures, although surgeries are sometimes required as the final method. A 75-year-old Japanese woman was diagnosed with solitary gastric varices. Initially, intraoperative splenic artery embolization was performed using the balloon transcatheter technique under general anesthesia. Laparoscopic splenectomy was performed safely owing to preoperative splenic artery embolization. Intraoperative indocyanine green (ICG) fluorescence angiography was performed following the injection of 5 mL of ICG; the remnant stomach was observed using laparoscopic equipment with an ICG imaging system, and blood flow from the remnant gastric artery was confirmed. The blood did not pool or wash out immediately, which confirmed successful devascularization of the stomach. The total operative time was 269 minutes, and the intraoperative blood loss was 500 mL. The patient's postoperative course was good, and at 21 days after the last operation, she was discharged from our hospital in remission. Real-time fluorescence angiography with ICG is a reliable and objective technique of assessing blood flow of the stomach. Accurate, extensive devascularization in the lower esophagus and upper stomach was performed using Hassab's procedure in combination with ICG imaging.
