Aim of the study:
A gastric tube is commonly used in thoracic esophageal reconstruction. When a gastric tube is not available, pedicled jejunum transfer and colonic interposition are alternative methods. Oral end of the reconstructed esophagus occasionally has poor blood flow and may result in partial necrosis of the oral segment We performed additional microvascular blood flow augmentation, the “supercharge” technique, to improve a blood flow circulation in the oral segment of the reconstructed esophagus.

A series of 86 esophageal reconstructions with microvascular blood flow augmentation using the “supercharge” technique were performed. Reconstructive methods included a gastric tube in five patients, a gastric tube combined with a free jejunual graft in one, an elongated gastric tube in eight, a pedicled colonic interposition in 22, and a pedicled jejunum in 50. Recipient vessels were used in neck or chest region.

The color and blood flow of the transferred intestine appeared greatly improved after microvascular blood flow augmentation. Thrombosis was noticed in three patients during the surgery, and all thrombosies were salvaged by re-anastomosis. There were only three patients with partial graft necrosis of oral segment, two patients with anastomotic leakage, one anastomotic stricture.

Augmentation of microvascular blood flow by this “supercharge” technique can be expected to reduce the risk of leakage and partial necrosis of the transferred intestine. This technique contributes to the successful reconstruction of esophageal defect.

Key words:
esophageal reconstruction – supercharge – microsurgery – blood flow augmentation
