食管拉网检查法是诊断食管癌的一种简便而有效的方法,对晚期狭窄型食管癌患者,用一般双腔橡胶管拉网时,由于质地较柔软,即使小号气囊也通不过狭窄部,给诊断带来一定困难。自1978年2月,我们在上海注射器一厂协助下,制成一种单腔塑料管拉网器,即用乙烯醋酸乙烯制成的长60厘米的八号或九号心导管,在距远端约0.5厘米处开一小孔,然后加上双腔管用的小号气囊和线网。经临床试用,效果较佳,现介绍如下: 病例选择:50例食管癌患者均进食困难(从半流质、流质到不能进水),X线示病变部明显狭窄,有的呈鼠尾状。年龄均在40岁以上。病变部位在食管上段者11例,中段13例,下段7例,贲门部19例,除一例因X线示高度狭窄而直接用单腔塑料管外,余49例都曾用过双腔橡胶管拉网器,用大小气囊均不能通过,有的先后检查6～7次,都未采集到肿瘤细胞。
Esophageal pull-net test is a simple and effective method for diagnosing esophageal cancer. For patients with advanced stenosis esophageal cancer, when using a general double-lumen rubber tube to pull the net, the texture is relatively soft, even though the small airbag can not pass through the narrow part. , to bring some difficulties in diagnosis. Since February 1978, with the help of Shanghai No. 1 Syringe Factory, we have made a single-cavity plastic pipe pulling device, namely a 60 cm long No. 8 or No. 9 heart catheter made of ethylene vinyl acetate, at a distance A small hole is made about 0.5 cm at the end, and then the small airbag and wire net for double lumens are added. After clinical trials, the results are better and are presented as follows: Case selection: All 50 patients with esophageal cancer had difficulty in feeding (from semi-fluid, fluid to non-influent). X-ray showed that the lesions were obviously narrow, and some were rat-tailed. Both are over 40 years old. The lesions were located in the upper esophagus in 11 cases, in the middle segment in 13 cases, in the lower segment in 7 cases, and in the cardiac cardiomysthesia in 19 cases. In addition to the single-lumen plastic tube used directly in the X-ray, the 49 cases had used double-lumen rubber tubing. Withdrawing the net device, the size balloon can not pass, and some have examined 6 to 7 times, and no tumor cells have been collected.
