Abstract    Several reconstruction techniques are possible after gastrectomy. But the best reconstruction technique hasn’t been admitted yet by now. The best reconstruction should meet the condition of maintaining satisfactory nutritional status and quality of life meanwhile keeping postoperative morbidity as low as possible. After total gastrectomy, Roux-en-Y reconstruction remains the easiest solution with satisfactory functional results and less complication. A pouch reservoir is suggested to make for patients with benign tumor and early gastric cancer, not for  patients with advanced tumor and poor prognosis, during Roux-en-Y reconstruction. After distal gastrectomy, Billroth Ⅱ or Roux-en-Y reconstruction should be preferred over Billroth I reconstruction because of lower postoperative morbidity and better oncologic margins. After proximal gastrectomy, esophagogastric anastomosis is the basic reconstruction method. Gastric remnant is made into gastric tube in the operation. The effect of pyloroplasty remains controversial. The further study is needed to improve the quality of life after operation.
