Introduction: Ileocolic interposition is often used for the reconstruction of patients with esophageal cancer with a history of gastrectomy. However, graft failure due to conduit necrosis has been reported in 0-5 % of patients. Salvage reconstruction surgery for this situation is considered challenging, and only a few cases of successful salvage operations following failure of ileocolic interposition have been reported.
Presentation of case: A 70s year-old male patient with a history of distal and total gastrectomy underwent subtotal esophagectomy for esophageal cancer. Reconstruction using a pedicled ileocolic interposition was performed; however, the ileocolic graft failed. After recovery of the nutritional status, salvage reconstruction was planned. Due to a history of Roux-en-Y reconstruction for gastric cancer, jejunal reconstruction was not considered feasible. Therefore, salvage reconstruction was performed using left colon interposition with microscopic supercharge and superdrainage anastomosis. The graft was pedicled by the left colic artery and the inferior mesenteric vein, and microscopic anastomosis was performed between the intrathoracic and middle colic vessels. The patient recovered without major complications and retained the ability to consume normal food.
Discussion: Microscopic supercharge and superdrainage vascular anastomosis have been reported to ensure augmented blood flow. This is the first case report of successful salvage reconstruction using the left colon interposition technique following failure of ileocolic interposition for esophageal cancer.
Conclusion: We report a case of salvage reconstruction using left colon interposition with microscopic supercharge and superdrainage anastomosis following failure of ileocolic reconstruction for esophageal cancer.
