Microvascular reconstruction in salvaging the gastric conduit post-esophagectomy after iatrogenic right gastroepiploic vessel injury

The preservation of the right gastroepiploic vessels is essential to ensure proper perfusion of the gastric conduit following esophagectomy. The loss of these vessels can lead to conduit ischemia or necrosis, resulting in significant postoperative complications. Traditional approaches such as colonic or jejunal interposition require extensive surgery and multiple anastomoses. In this report, we present our successful experience of salvaging the gastric tube through microvascular reconstruction following iatrogenic injury to the right gastroepiploic vessels in two cases. The first case involved re-anastomosis of the right gastroepiploic vein, while the second case required reconstruction of both the artery and vein during esophagectomy in a single setting. The procedures were performed by an experienced surgical team using microvascular techniques. Both patients had uneventful postoperative courses without any anastomotic leakage or major complications. Adequate perfusion of the salvaged gastric tube was confirmed intraoperatively using indocyanine green fluorescence perfusion imaging. In conclusion, immediate microvascular reconstruction offers a viable solution by restoring perfusion of the gastric tube in cases of right gastroepiploic vessel injury during esophagectomy.
