上消化道重建主要包括全胃切除、胃次全切除、远端胃切除、近端胃切除和胰十二指肠切除术等术后重建。重建手术的原则是简便易行，能提高病人的生存质量，不增加并发症发生率和病死率。上消化道消化、运动、排空是一个非常复杂的生理过程，涉及神经、体液及激素调节等因素。严格来说，各种人工重建术无法替代消化道原有复杂的解剖和生理功能。

Impact of various reconstructions after surgery for upper digestive tract on quality of life        ZHAN Wen-hua. Department of Surgery, the First Hospital, Sun Yat-sen University, Guangzhou 510080, China
Abstract    Reconstructions of upper digestive tract after surgery are commonly used in total gastrectomy, subtotal gastrectomy, distal and proximal gastrectomy and pancreaticoduodenectomy.  It should be emphasized that the principle of reconstruction should be simple and feasible, beneficial to quality of lift of patients, and non-increasing morbidity and mortality. Digestion, absorption, motility and emptying of upper digestive tract are complex physiological mechanisms including factors of nerves, body fluid and hormones. Strictly speaking, primary complex anatomy and physiologic functions of upper digestive tract are unlikely be substituted by the artificial reconstruction after surgery.
