Indocyanine green fluorescence imaging ensures perfusion of the remnant stomach during laparoscopic splenectomy in a patient after distal gastrectomy: A case report.

Background: After distal gastrectomy, ischemic necrosis of the remnant stomach is a rare but serious complication. For distal pancreatectomy or splenectomy, ensuring adequate blood supply to the remnant stomach is important for patients with a history of distal gastrectomy. We report a case of successful splenectomy with indocyanine green (ICG) used to evaluate the blood supply to the remnant stomach in a patient after distal gastrectomy.

Methods: A 65-year-old woman who underwent distal gastrectomy for gastric cancer a year earlier had a splenic tumor that was increasing in size. We planned laparoscopic splenectomy because there was a possibility of a malignant splenic tumor. Intraoperative ICG fluorescence imaging confirmed perfusion of the remnant stomach. The patient was discharged on postoperative day 8 after an uncomplicated postoperative course.

Conclusions: ICG fluorescence imaging is useful for evaluating blood flow to the remnant stomach during laparoscopic splenectomy in patients after distal gastrectomy.
