Typical non-gynecological uses include dilating a stenotic percutaneous gastrostomy stoma, anal dilation and urethral dilation in the case of stricture or stenosis. Indications for a D&C in the pregnant patient include elective termination of pregnancy, early pregnancy failure, evacuation of a molar pregnancy, or suspected retention of products of conception. The pregnant D&C is usually performed with either manual or electric vacuum aspiration. In addition, a D&C may be used to evaluate the chorionic villi in a patient who has a pregnancy of unknown location.

If local anesthesia is used, then the cervix and lower uterine segment should be injected. Most commonly, 1% lidocaine is adequate. A tenaculum is used to grasp the anterior lip of the cervix and pull towards the introitus with the non-dominant hand. The traction will stabilize the uterus and reduce the cervicouterine angle to decrease the risk of uterine perforation. Routine use of uterine sound for cavity length does not benefit the procedure unless the uterus was not palpable on the initial bimanual examination. Not all materials are safe for your special place so you’ll definitely want to be mindful of what your device is made of.

If you’re entirely new to anal penetration or have a medical condition that causes rectal pain, silicone is softer and more flexible than other materials. To find the final size of the Hegar dilator your child will use, see chart below. When Starting Dilatations, Your Child Is: Look for dilators made from body-safe materials, such as medical-grade silicone, that are free of phthalates and BPA.

Chemical ripening agents are prostaglandin analogs or progesterone antagonists, which soften or prime the cervix. [8]Misoprostol, a prostaglandin analog, is the most common vaginally-administered medication. Misoprostol is a safe and effective form of cervical preparation and can be administered on the same day as the procedure. [9] [10]The progesterone antagonist, mifepristone, is as effective as misoprostol; however, its high cost and limited availability prohibit routine use. The Society of Family Planning does not recommend any cervical preparation for first-trimester abortions unless the patient is at an increased risk of complications such as cervical lacerations, inadequate cervical dilation, or uterine perforation. [8]Cervical priming is timely and can have uncomfortable side effects. However, using a cervical priming agent should be considered in later first-trimester abortions performed between 12 and 14 weeks, and in patients for whom cervical dilation may be challenging, such as adolescents or those with a history of cervical conization. If met with resistance — which is totally normal — gently remove the dilator, reapply more lube, and try again. Every week, you will increase the size of the dilator, using the next larger size. Continue to dilate your child’s anus two times a day until you get to the goal size set by the doctor.If you’re using a silicone dilator, use a water-based lube like #LubeLife instead. Remember: Silicone breaks down silicone. Choose the best position Cervical injury or lacerations to the lip of the cervix typically occur when too much traction is applied to the cervix during dilation or manipulation. Most lacerations can be managed with pressure, silver nitrate, or ferric subsulfate. Occasionally suture ligation is needed. If there is an injury to the endocervical canal, pressure or suture should be attempted first. If there is no response, then balloon tamponade or uterine artery embolization with further evaluation for abdominal or retroperitoneal bleeding should be considered. Cervical incompetence (CI) is one of the main causes of premature birth or miscarriage in the second trimester. According to statistics, 8% of miscarriages in the second trimester and premature births are due to CI ( 1). If a patient has a history of typical painless cervical dilation during the second trimester, and a No. 7 Hegar dilator can pass through the internal cervical os without resistance during the nonpregnancy period, the diagnosis of CI can be confirmed ( 2). The surgical treatment of CI is cervical cerclage which refers to a variety of procedures that use sutures or synthetic tape to reinforce the cervix. Cervical cerclage can be done through the vagina (transvaginal cervical cerclage) or, less commonly, through the abdomen (transabdominal or laparoscopic cervical cerclage). The prophylactic cervical cerclage should preferably be performed before or in the early period of pregnancy. Both approaches have their own advantages and disadvantages. Currently, the most commonly used method is the transvaginal approach, but upon its failure, laparoscopic cervical cerclage is recommended. Pregnancy outcomes: the mean delivery gestational age was 37.2±1.17 weeks (range, 35 to 38). One patient underwent cesarean section due to preterm labor at 35 weeks of pregnancy without premature rupture of membranes; the remaining 5 patients underwent elective cesarean sections at 37 to 38 weeks. six patients who underwent cesarean section experienced no serious surgical complications. The intraoperative blood loss was 100–800 mL, with an average of 283±263 mL. If it goes in easily, you can start again, repeating these steps with the next size up in your kit.

During the process of dilation, the cervix may have to be stabilized with a tenaculum, and then the dilators are slowly entered into the cervical canal with a lubricant, starting with a thin, low Hegar number rod and progressing gradually to larger numbers. [11] The dilators can also be used to sound the uterus. Anatomically the cervix is the lower part of the uterus. The cervix protrudes into the vaginal lumen and is visible on speculum examination. The external cervical os opens into the endocervical canal, which extends proximally to the level of the internal cervical os. The endocervical canal is contiguous with the endometrial cavity. The external and internal cervical ossaare narrower than the endocervical canal; dilation of these openings is often needed to accommodate the instruments used in a D&C.A patient's inability to tolerate an EMBor a failure to obtain a tissue sample sufficient for diagnosis would prompt further endometrial sampling; a D&C may be used in this circumstance. Likewise, cervical stenosis, persistent abnormal bleeding, or postmenopausal bleeding after a benign EMB may warrant a D&C. A D&C may be indicated to exclude endometrial cancer ina patient diagnosed with endometrial intraepithelial neoplasia via EMB. Hellman LM, Pritchard JA. Williams Obstetrics, 14th edition. Appleton Century Croft, 1971. p.1089f. If a healthcare provider has recommended you use dilators, chances are they’ve also provided some guidance as far as size. Removal should be slow and steady. Try to keep the dilator in line with your anus and rectum as you gently pull it out. What should you do if…? HL Dilators TM are lengthier compared to the Hegar dilators. This additional length is advantageous, especially when a subcoronal approach is preferred for penile prosthesis implantation. Due to the 25 cm length of the HL Dilators TM, even from a subcoronal corporotomy, the surgeon can dilate the corpus cavernosum down to the crus of penis in one single move and reliably measure the corpus. In most cases, the distance from the subcoronal corporotomy to the crus of penis is longer than the Hegar dilator’s length [ 5].

In addition to the points discussed above, all HL Dilators TM also act as a precise sizer. When using a Hegar dilator, the surgeon must use a separate sizer tool, whereas, with the HL Dilator TM, the surgeon can size the corpus cavernosum with the same dilator as he or she completes the dilation process [ 6]. Because a single tool has two varying dilator tips, the authors expect a positive post-operative outcome regarding inflammation and infection since fewer surgical tools are introduced inside the corpus cavernosum. Uterine sounding may be performed prior to embryo transfer to determine the uterine depth and how easily an embryo transfer catheter can be passed through the cervix. In this case, it may also be called a trial transfer. [1] You will start by dilating your child’s new anus two times each day – one time in the morning and one time in the evening. The patient should be placed in the dorsal lithotomy position. Then, a bimanual examination should be performed to assess the uterine size and position.Dilation and curettage (D&C) is one of the most common invasive procedures in the United States. The procedure can be performed on a pregnant or nonpregnantpatient and be either diagnostic or therapeutic. Sometimes the circumstances lead to a diagnostic procedure becoming therapeutic. A patient seeking elective termination or management of a missed, incomplete, or inevitable abortion in the first trimester of pregnancy at less than 14 weeks of estimated gestational age could be offered this surgical procedure or medical management. Dilation and evacuation is a similar procedure employed at an estimated gestational age of greater than 14 weeks and is outside this activity's scope. The3 most common types of dilators are steel Pratt dilators, Hank dilators, and Hegar dilators. No trials have compared the safety or efficiency of these different dilator sets. [8]
