title: Revascularization using the short gastric vessels of the gastric tube after subtotal esophagectomy for intrathoracic esophageal carcinoma.
abstract: BACKGROUND
  Maintaining sufficient blood flow to the substitutive organ after esophagectomy is essential to decrease the risk of anastomotic leakage.
  
  
  METHODS
  Forty-one patients underwent subtotal esophagectomy for intrathoracic esophageal carcinoma and reconstruction using the gastric tube. Additional vascular anastomosis between the short gastric vessels and the vessels in the neck was performed in 15 patients. Tissue blood flow was measured by laser Doppler flowmetry before and after vascular anastomosis. The incidence of anastomotic leakage in the revascularization group was compared with that in the remaining 26 patients.
  
  
  RESULTS
  Venous anastomosis was performed in 14 patients and arterial anastomosis in 9. There was a significant increase in tissue blood flow after venous anastomosis alone (mean percent increase: 36%; p < 0.01), and after arterial and venous anastomoses (mean percent increase: 108%; p < 0.01). No anastomotic leakage was observed in the revascularization group; six patients (23.1%) in the control group had leakage (p < 0.05). Patients in the revascularization group started taking a meal 10.0 +/- 0.4 days postoperatively, compared with 15.1 +/- 1.8 days in the control group (p < 0.05).
  
  
  CONCLUSIONS
  Additional vascular anastomosis in esophageal reconstruction after subtotal esophagectomy achieved good results. This procedure can reduce the risk of anastomotic leakage and may be useful for esophageal reconstruction.
