旧式环形节育器并发肠损伤,往往是套在肠管上,引起肠绞窄或肠梗阻。新式IUD由多乙烯塑料浸涂钡盐构成,有些IUD有小的开口或呈线状并有锐利双臂,近用带药IUD能释放铜或孕酮。新式IUD由于特殊外形结构,可穿通子宫引起大肠或小肠损伤,这种损伤常因不被怀疑或难于诊断而延误手术处理。 IUD引起肠穿孔妇科少见,当有腹部症状与体征又找不到IUD的尾丝时,应警惕有穿孔可能。IUD引起子宫底穿孔约为1∶350至1∶2,500。术者的技巧与经验是决定穿孔与否的因素,但推出放置法与IUD不密封于放置器者,可增加穿孔危险性。8
The old IUD with intestinal injury, often set in the intestine, causing intestinal strangulation or intestinal obstruction. The new IUD is made of polyethylene impregnated with barium salts. Some IUDs have small openings or lines and have sharp arms. Proximal IUDs release copper or progesterone. The new IUD due to the special shape of the structure, can be caused by the uterus to cause damage to the large intestine or small intestine, such damage is often not suspected or difficult to diagnose and delay the surgical treatment. IUD caused intestinal perforation gynecological rare, when there are signs and symptoms of the abdomen IUD can not find the tail wire, should be alert to the possibility of perforation. IUD caused uterine perforation at about 1: 350 to 1: 2500. The skill and experience of the surgeon is a factor that determines whether or not to perforate, but the introduction of placement and the lack of sealing of the IUD in the placer increase the risk of perforation. 8
