Objective To explore the clinical effects of ileus tube in treatment of colonic obstruction caused by colorectal carcinoma. Methods Thirtytwo colorectal carcinoma patients with colonic obstruction admitted to our hospital from December 2005 to December 2008 were given onestage radical excision and anastomosis after transnasal or transanal placement of ileus tube for colonic decompression and drainage. Results Combined placement of transnasal and transanal ileus tube was successfully carried out in 19 cases, while the other 13 cases were treated only with transnasal ileus tube. Abdominal pain and distention of all cases were relieved 12-36 h after tube placement, while those of 26 cases disappeared 48-96 h later. Compared with before tube placement, abdominal circumferences of all cases were significantly reduced after tube placement, the mean reduction rate was (81.3±19.6)% vs. 100% (t=3.586, P=0.02). All cases were successfully treated by onestage radical excision and anastomosis 5-7 d after placement, and no serious complications such as peritoneal infection, anastomotic leakage etc. were found. Conclusion Preoperative intubation of ileus tube can enhance the therapeutic effects of onestage radical excision and anastomosis in patients with colorectal carcinoma combined with colonic obstruction.
目的 探讨乳房肿物体表定位膜对乳腺彩超结果的影响。方法 回顾性分析2010年12月至2011年1月期间，笔者所在医院乳腺门诊检查触诊阴性的180例患者共236个乳房肿物贴膜前后的彩超检查结果，分析其血运、边界、钙化及分级情况的变化。结果 贴膜后，236个肿物中有2个血运情况有变化，7个边界有变化，5个钙化情况有变化，5个分级有变化，但贴膜前后乳房肿物的血运（P=0.500）、边界（P=0.136）、钙化（P=0.082）及分级（P=0.172）变化情况比较差异均无统计学意义。结论 乳房肿物体表定位膜不影响乳房肿物的彩超检查结果。
