To assess the use of self-expanding metallic stents in patients with inoperable malignant antrum-pylorus-duodenal obstruction.
Six patients underwent implantation of a Wallstent self-expanding metallic endoprosthesis (20 mm in five patients and 16 mm in one). In five patients a catheter (Berenstein) was introduced perorally into the stomach. A guidewire (Terumo) was introduced through the catheter and advanced through the antrum-pylorus-duodenal stenosis. The guidewire was removed and a 260-cm-long, 0.035" superstiff guide (Amplatz) was introduced. After the catheter was removed the stent assembly was introduced. In the last patient the stent was implanted through a percutaneous gastrostomy.
Treatment of inoperable gastric outlet obstruction caused by tumor compression is difficult and unsatisfactory. Peroral implantation of self-expanding metallic stents resulted in successful palliative therapy of antrum-pylorus-duodenal stenosis in six patients in whom surgery was not possible because of advanced disease and poor general condition. On average, patients were able to eat during 41 days. One patient is tolerating oral intake at 3 months.
Implantation of stents resulted in palliative relief of malignant antrum-pylorus-duodenal obstructions.
评估自膨式金属支架在无法手术的恶性胃窦-幽门-十二指肠梗阻患者中的应用。
6例患者植入了Wallstent自膨式金属内支架（5例为20mm，1例为16mm）。5例患者经口将导管（Berenstein）插入胃内。通过导管插入导丝（Terumo），并使其穿过胃窦-幽门-十二指肠狭窄处。移除导丝后，插入一根260cm长、0.035英寸的超硬导丝（Amplatz）。移除导管后，插入支架组件。最后1例患者通过经皮胃造口术植入支架。
由肿瘤压迫导致的无法手术的胃出口梗阻的治疗困难且效果不佳。经口植入自膨式金属支架成功地对6例因疾病晚期和全身状况差而无法进行手术的胃窦-幽门-十二指肠狭窄患者进行了姑息治疗。患者平均能够进食41天。1例患者在3个月时能够耐受经口进食。
支架植入可缓解恶性胃窦-幽门-十二指肠梗阻。
