To evaluate the usefulness of a newly designed multifunctional coil catheter for stent placement in patients with upper gastrointestinal tract strictures.
Constructed in our research laboratory, the coil catheter was used in 202 consecutive patients with malignant (n = 191) or corrosive (n = 11) upper gastrointestinal tract strictures. The coil catheter was made of a stainless-steel coil (1.3-mm inner diameter, 1.8-mm outer diameter), a 0.4-mm nitinol wire, a polyolefin tube, and a hemostasis valve. Usefulness of the coil catheter was evaluated based on whether the coil catheter could pass the stricture over a guide wire and whether measurement of the stricture length was possible while the guide wire was in place.
The passage of the coil catheter over a guide wire beyond the stricture was technically successful and well tolerated in 199 of 202 patients (99%). Negotiation of a guide wire or a coil catheter through the stricture of the stomach (n = 2) or duodenum (n = 1) under fluoroscopic guidance failed in three patients. In two of these three patients, it was possible to negotiate a guide wire and a coil catheter under combined endoscopic and fluoroscopic guidance; it was not possible in the third. There were no procedure-related complications.
The newly designed multifunctional coil catheter is useful in stent placement in patients with upper gastrointestinal tract strictures.
评估一种新设计的多功能线圈导管在上消化道狭窄患者支架置入中的应用价值。
该线圈导管在我们的研究实验室构建，用于202例患有恶性（n = 191）或腐蚀性（n = 11）上消化道狭窄的患者。线圈导管由不锈钢线圈（内径1.3毫米，外径1.8毫米）、0.4毫米镍钛诺丝、聚烯烃管和止血阀制成。基于线圈导管能否在导丝上越过狭窄以及在导丝就位时能否测量狭窄长度来评估线圈导管的应用价值。
202例患者中有199例（99%）在技术上成功且耐受性良好地将线圈导管越过导丝通过狭窄部位。在3例患者中，在透视引导下将导丝或线圈导管通过胃（n = 2）或十二指肠（n = 1）的狭窄失败。在这3例患者中的2例，在内镜和透视联合引导下能够将导丝和线圈导管通过狭窄；第3例则无法通过。没有与操作相关的并发症。
新设计的多功能线圈导管在上消化道狭窄患者的支架置入中有用。
