1. From this surgery, it was known that there was a leak in the recta and the dejecta was leaked to abdomen probably from the place where the stapler was used. 从第二次手术得知，病人是多发性肠间脓肿引起的感染性休克，怀疑造成感染的原因是直肠手术发生吻合口瘘（因直肠有漏洞造成粪便漏到腹腔而引起感染）。
2. Results: Vasa recta in jejunum frequently divided into three branches-two long and one short branches, in the ileum, it often divided into two branches-one long and one short branches. 结果： 正常小肠动脉分布具有一定规律性，空肠段直动脉通常分为三支（两长支，一短支），回肠段直动脉通常分为两支（长、短各一）。
3. Most pigmentations were present on head or around the tip of the finger and toe. Most polyps were present in colon and recta. The pathological type of most polyps was hamartomas and adenoma. 结果全国各省市自治区均有病例报道，黑斑分布以头部及手足为常见，以大肠息肉最为常见，病理以错构瘤性息肉和腺瘤性息肉为主，易合并恶性肿瘤。
