低位直肠癌前切除术后肛门直肠内压力变化的临床研究

目的研究低位直肠癌前切除术后患者肛门直肠内压力的变化,探讨其与吻合口瘘发生的关系。方法42例直肠癌前切除患者,术中将1根乳胶引流管和2根分别为10号、6号的吸痰管固定在一起,通过肛门置于肠腔,达吻合口上方约5 cm处,并将这3根引流管缝合固定在肛周皮肤上,分别接引流袋,术后采用中心静脉压测压系统,以静止测压法测定术后1~6 d内肛门直肠内压力的变化。结果术后2例发生吻合口瘘,未瘘组患者术后肛门直肠内压力变化呈先增高后降低的趋势,第4 d压力最高;而吻合瘘组患者的肛门直肠内压基本呈持续增高的趋势。吻合口瘘组第4、5、6 d的压力均高于未瘘组。结论术后肛门直肠内压力的变化与吻合口瘘的发生有关,可能是导致术后吻合口瘘的原因之一。

The Clinical Research of the Anorectal Pressure Changes after Anterior Resection for Low Rectal Cancer

Objective To study anorectal pressure changes after the low anterior resection of rectal cancer.Methods After the anterior resection,one latex drainage tube and two sputum tubes were put together above the stoma for 5cm through the anus.At the first to the sixth day after operation,the central venous pressure measurement system was used through the tubes to measure the static anorectal pressure in 42 cases.Results There were 2 cases occurred stoma leakage.In the 40 un-leakage cases,the anorectal pressure sh...
