人类没有了胃和结肠会怎么样？
What if humans have no stomach and colon?

本文通过一位因胃癌施行全胃切除、7年后又因结肠多发息肉癌变行全结肠切除的病例，论述了胃和结肠的生理解剖关系，它们被切除的适应证、术式选择、无瘤操作及杀瘤技术的应用，以及术后并发症的预防等问题。此患者术后随访近3年，目前日常生活正常，从而证明了人类在去除胃和结肠的情况下是可以生存的。
This article presented a patient whose stomach was totally cut for gastric cancer and colon was removedseven years later for colon cancer associated with malignant multiple polyposis. Based on the case, we aim to discussthe anatomic-physiological relationship between the stomach and the colon, the indications, operation modes, tumor-freeoperative skills, and tumor-killing techniques of the whole gastric-colon resection, and the prevention of postoperativecomplications. The near 3-year follow-up after the operation showed the patient had a normal daily life, which proves thata person can live on after the removal of the stomach and colon
