[ 摘要 ] 宫腔镜手术是目前妇科常见的手术之一，用于诊治子宫病变，如子宫内膜息肉、黏膜下肌瘤等，术前需 要扩张宫颈，使宫腔镜顺利进入子宫腔。宫颈预处理是宫腔镜手术中的重要组成部分，充分和适当的宫颈扩 张可缩短手术时间，减少并发症及不良反应的发生。目前临床常用的方法主要有物理及药物两种，如海藻棒 或导尿管机械性扩张、阴道内置米索前列醇或卡前列甲酯、静脉滴注间苯三酚等。不同的方法适用人群不同， 且各有其优缺点，临床对术前宫颈预处理的方法仍未达成统一共识。本文对近年来临床常用的宫颈预处理方 法进行总结，以期为临床诊疗提供依据。
[Abstract] Hysteroscopic surgery is one of the common operations in gynecology, which is used to diagnose and treat uterine lesions, such as endometrial polyps and submucosal myoma. Before surgery, the cervix needs to be dilated to allow hysteroscopy to enter the uterine cavity smoothly. Cervical pretreatment is an important part of hysteroscopic surgery. Adequate and appropriate cervical dilatation can shorten the operation time and reduce the incidence of complications and adverse reactions. At present, there are two main methods commonly used in clinical practice, such as seaweed sticks or mechanical catheter dilation, intravaginal Misoprostol or Carboprost Methylate, intravenous drip of Phloroglucinol, etc. Different methods are suitable for different populations, and each has its own advantages and disadvantages. There is still no consensus on the method of cervical pretreatment. This article summarizes the commonly used cervical pretreatment methods in clinical practice in recent years, in order to provide a basis for clinical diagnosis and treatment.
