Remnant gastric ischemia is the most significant complication in distal pancreatectomy (DP) after distal gastrectomy (DG). Some studies have reported the safety of asynchronous DP in patients who underwent DG. We report a case of simultaneous robotic DG and DP. A 78-year-old man was diagnosed with gastric and pancreatic cancer.

We preoperatively confirmed the absence of anomalies in the left inferior phrenic artery. Robotic simultaneous DG and DP was performed; subtotal resection of the stomach was carried out, enabling the left inferior phrenic artery to maintain perfusion of the remnant stomach, even after ligation of the splenic artery.

The remnant stomach was preserved as scheduled, and indocyanine green fluorescence imaging confirmed sufficient remnant stomach tissue perfusion. Robotic surgery using the da Vinci surgical system (with a fluorescence imaging system and technology enabling surgical precision) is suitable for this surgical procedure because it considers tumor radicality and allows for function preservation.
