Objective To introduce the technique of esophageal intraluminal stenting and assess its effect on the prevention of development of stenosis in patients with esophageal burns. Methods Thirty-three patients were admitted less than 3 weeks after ingestion of caustic agents. The second-or third-degree injuries were confirmed by esophogoscopy in all cases, but one with esophageal perforation at admission. Esophageal stenting was performed in all patients and these stents were kept in place for 4 to 6 months. Results There was no death in the series. All patients had a normal intake of food after removal of the stents, and stricture was not found on barium swallow test. Follow-up from 1 to 60 months five cases developed esophageal stenosis from 2 to 3 months after extracting the stents. One of them responded to esophageal bougienage, the remaining 4 patients required esophageal reconstruction and took a normal diet postoperatively. The other 28 patients have a normal diet after the stent removal. Conclusion The esophageal intraluminal stenting is able to prevent the formation of stricture in the aftermath of esophageal burns and its effect will be enhanced plus administering isoniazid.
【摘要】 目的 探讨经鼻胃镜在食管狭窄扩张和支架置入术中的作用。 方法 2007年10月-2009年3月对28例癌性食管狭窄以及并发食管-气管瘘的患者行PENTAX(EG-1580K)超细经鼻电子胃镜检查,计算插入深度,并进行扩张和支架治疗,在胃镜直视下调节输送器内支架上端的位置,观察扩张效果、支架放置成功率、定位的准确性以及并发症情况。 结果 全部患者均行扩张治疗,效果良好,支架一次性放置全部成功,定位准确,自膨满意,最狭窄处的内径由(4.8±1.2)mm扩至(12.5±1.5)mm,食管气管瘘被覆盖治疗效果好,患者的吞咽困难评级由3.25±0.58降至0.94±0.59。 结论 在食管狭窄扩张和支架置入术中应用经鼻超细胃镜患者依从性好,方法简便,安全有效。【Abstract】 Objective To explore the role of nasal endoscopy in the esophagostenosis expansion and esophageal stent. Methods PENTAX (EG-1580K) ultrafine nasal endoscopy was used in 28 patients (October 2007-March 2009) with esophageal cancer complicated with esophagostenosis and fistula to check the e-calculated insertion depth, stent expansion and the average diameter expansion. The endoscopy was carried under the direct vision with the location of the top bracket in order to ensure the accurate stent placement, all without X-ray assist. The success rates of stent placement, positioning accuracy, as well as complications were evaluated. Results The expansion treatments were successful in all patients with one-off operation. The narrowest part increased from (4.9±1.6) mm to (12.7±1.5) mm, and the esophageal fistula was covered. The rating of dysphagia decreased from 3.15±0.68 to 0.91±0.49. Conclusion Nasal endoscopy is simple, safe and effective in the treatment of ultrafine expansion for esophagostenosis and stent implantation with good compliance.

ObjectiveTo develop an experimental model of gastroesophageal reflux-induced esophageal stricture in rats and explore the mechanism of esophageal stricture. MethodsA total of 30 male Sprague-Dawley (SD) rats by random number table method were randomly divided into three groups as follows: an operation+acid perfusion group, first the models of lower esophageal sphincter relaxation and hiatal hernia were made, and then the rats’ esophagus were perfused with hydrochloric acid-pepsin; acid perfusion group, the rats’ esophagus were directly perfused with hydrochloric acid-pepsin; and control group, rats’ esophagus were perfused with normal saline. After 4 weeks of continuous perfusion, the esophageal mucosal injury of SD rats in each group were observed, and the concentrations of inflammatory cytokines [tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-18] in esophageal tissues were detected by enzyme-linked immunosorbent assay. ResultsIn the operation+acid perfusion group, esophageal stricture was formed in 2 SD rats, but no esophageal stenosis was found in the acid perfusion group and the control group. The body weight of rats in the operation+acid perfusion group and the acid perfusion group were lower than that in the control group (P<0.05). The esophageal mucosal injury scores of rats in the operation+acid perfusion group and the acid perfusion group were higher than that in the control group (P<0.001), and the operation+acid perfusion group was higher than that in the acid perfusion group (P=0.014). The concentrations of TNF-α, IL-1β and IL-18 in esophageal tissues were higher in the operation+acid perfusion group and the acid perfusion group than that in the control group (P<0.001), and the operation+acid perfusion group was higher than that in the acid perfusion group (P<0.001). ConclusionsThe anti-reflux barrier is an important part of preventing gastroesophageal reflux disease. The destruction of anti-reflux barrier, hydrochloric acid-pepsin perfusion and inflammatory cytokines jointly induced esophageal inflammation and injury, and even caused esophageal stricture.
