内支架治疗消化道恶性梗阻的探讨

目的探讨内支架治疗消化道恶性梗阻和食管-支气管瘘的有效性和安全性。方法71例消化道恶性梗阻和食管-支气管瘘患者采用永久性部分覆膜镍钛合金内支架治疗,全部病例均在DSA监视下经口或肛门将支架置放于梗阻或瘘口部位,术前术后均做造影对照,根据进食进水和排便情况评价疗效。结果上消化道支架置入后恢复饮食,饮水后无呛咳62例(96.9%);乙状结肠和直肠支架置入后肠梗阻症状均即刻解除;术后支架移位2例(2.8%);再狭窄2例(2.8%);声音嘶哑1例(1.4%);胸部剧烈疼痛2例(2.8%),轻度疼痛12例(16.9%);大出血1例(1.4%),经相应处理后全部好转。结论永久性部分覆膜镍钛合金内支架置入术是消化道恶性梗阻和食管-支气管瘘的有效治疗方法,操作简便,安全性高。

Efficiency and safety of the intraluminal stent as a treatment malignant obstruction of the digestive tract

Objective To evaluate the efficiency and safety of intraluminal stent as a treatment of malignant obstruction of digestive tract and esophago-bronchial fistula. Methods In total 71 patients suffered with malignant obstruction or esophago-bronchial fistula were treated with permanent nickel-titanium alloy, partially covered stents. All the procedures were performed under DSA guidance. Inserted via the oral anal access, the stents were placed at the sites of obstructions or the fistulas. Esophagogram or colonogram were done before and post the intervention. The clinical efficiency was assessed by function of swallowing or defecation in follow-up. Results In 62 patients (96.9%), function of swallowing was restored after the stent was placed in upper digestive tract without drinking triggered coughing. Symptoms were immediately relieved after the stent was placed in sigmoid colon or rectum. Displacement of stents was seen in 2 cases (2.8%); restenosis in 2 (2.8%); hoarse voice was noted in 1 case (1.4%); intense thoracic pain was complained in 2 cases (2.8%); mild pain was noted in 12 cases (16.9%); and massive hemorrhage was complicated in 1 case (1.4%). All complications were successfully controlled after proper treatment. Conclusion It is an effective, easy and safe method to treat malignant obstruction of digestive tract or esophago-bronchial fistula using partially covered nickel-titanium alloy stent.
