Results The average operation time was 23.5min. The average hospital stay was 3.5d. The correction of the prolapsed hemorrhoids was satisfied in 93.5% patients. Intraoperative hemorrhea occurred in two cases because the large range rectum mucosa was uncompletely stapled or cut. Urine retention occurred in 184 cases (31.9%), anal pain in 357 cases (62%) and a second operation were performed in 3 cases because of postoperative hemorrhea. A total of 484 cases were followedup for 14 years. The postoperative satisfaction rate of symptom improvement was 94 .3%. Four cases underwent thrombosed external hemorrhoid resection. Other patients had no recurrence, no anal stenosis and no fecal incontinence.

However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。

Removed veins research demonstrate the main reason of transplanted vessel stenosis is the hyperplasic of endothelium. Which is a popular reaction when set vein into arteral circulation. It is caused by the transmission of smooth muscle cell to endothelium and proliferate and release extracellular matrix. These are two characteristics in pathology erg middle layer of sue proliferates and migrate to endothelium in early and excel of end thulium aggregate in cater stage. The colic and the motivation of end thulium hyper is the hyper of sac.

在mRNA水平，随着移植术后时间的推移，ECE的表达逐渐增高，手术后1W-2W达到高峰2W后表达逐渐下降，于8W左右趋于平衡，ET-1的表达与ECE的动态变化过程相似，亦于术手1W-2W达到高峰，在8W左右趋于平稳在蛋白质水平，以ET-1抗体免疫组织化学染色结果显示ET-1主要在血管内收细胞及平滑细胞胞浆中表达，尤其是中膜平滑肌细胞更为明显，呈棕黄色颗粒。
