The procedure is illustrated by an instructive video article that standardizes the essential steps to make the technique ergonomic and easy to perform with step-by-step explanations. The sutures must include the rectovaginal fascia (Figure 4), which provides support to the posterior vagina. During the second stage of labor, perineal massage and application of a warm compress to the perineum are beneficial. Skin sutures have been shown to increase the incidence of perineal pain at three months after delivery.15 [Evidence level B, uncontrolled trial] If the skin requires suturing, running subcuticular sutures have been shown to be superior to interrupted transcutaneous sutures.16 The 4-0 polyglactin 910 sutures should start at the posterior apex of the skin laceration and should be placed approximately 3 mm from the edge of the skin. Live male infant with Apgars of 9 and 9. An alternative technique is overlapping repair of the external anal sphincter. [4]First degree lacerations that are hemostatic and do not distort the natural anatomy do not need to be repaired. By inserting an index finger into the rectum and the thumb into the vagina you will be better able to feel the tone of the sphincter. Results: A total of 104,301 deliveries were assessed for breakdown of perineal laceration. So if they gave length of the repair, depth, etc. The more severe the laceration, the longer the return to normal sexual function.[10]. Braided absorbable suture is associated with less pain during recovery and a lower incidence of wound dehiscence. 187. In 2015-16, 5,639 such lacerations were recorded in Australian public hospitals. This aids in placement of the interrupted plicating sutures over the injured area and will improve resting tone of the anus. Risk factors associated with anal sphincter tear: A comparison of primiparous patients, vaginal birth after cesarean deliveries, and patients with previous vaginal delivery. These injuries do not require immediate repair; hence, an inexperienced physician can delay the procedure for a few hours until appropriate support staff are available. [2]There is also a risk of infection and wound break down with any vaginal repair. MeSH The wound was copiously irrigated. Female Pelvic Med Reconstr Surg, 27 (2021), pp. vol. Classification of episiotomy: towards a standardisation of terminology. POSTOPERATIVE DIAGNOSES: Effective repair requires a knowledge of perineal anatomy and surgical technique. Use of a large needle facilitates proper suture placement. Location: __________________ The repair consists of either end-to-end or overlapping plication of the disrupted external anal sphincter and capsule using interrupted or figure-of-eight . vol. The vaginal muscles are still intact. Laceration-A spontaneous tear to the vulva (perineum, vagina, labia) that occurs during the birth process a. N Engl J Med. It is, however, always possible to sustain a third degree laceration without any of the previously mentioned risk factors. degree tears are identified, repaired and followed up with both obstetric and physiotherapy input. Splenic laceration. A rectal exam can improve evaluation of the extent of the injury. Cervical lacerations 5. He was taken to the emergency room where he was noted to have a profusely bleeding submental facial laceration, approximately 4 cm in total length; however, it was L shaped. [8]The midline episiotomy is the most commonly performed in the United States and is associated with a higher frequency of severe perineal lacerations. Research and data collection on obstetric lacerations can be challenging given variations in classification and difficulty separating independent risk factors. Because it is such a severe injury, a fourth degree tear must be repaired in theatre by an experienced surgeon. The entire wound edge was reapproximated in the configuration in which it had been avulsed. vol. 3rd degree tears extend to the anal sphincter without affecting the rectal mucosa. Anal sphincter disruption during vaginal delivery. Cochrane review involving four trials with 2,497 women, Cochrane review with four studies involving 1,799 women for warm compresses, six studies involving 2,618 women for perineal massage, and a systematic review of manual perineal support including six randomized and nonrandomized studies involving 81,391 women, Cochrane review involving two studies with 154 women showing similar results in both groups, Randomized controlled trial of 1,780 women with first- or second-degree lacerations, Randomized controlled trial of 102 patients, with 74 patients randomized to surgical glue, Cochrane review involving 16 studies with 8,184 women showed improvements in continuous suture group but no differences in long-term pain, Cochrane review involving 10 studies with 1,825 women showed improvement in pain compared with no treatment, Laceration involving the perineal muscles but not involving the anal sphincter, Laceration involving the anal sphincter muscles, Laceration involving the anal sphincter complex and rectal epithelium, Large fetal weight (> 4,000 g [8 lb, 13.1 oz]), Occipitotransverse or occipitoposterior position at delivery, Epidural anesthesia (increases risk of severe lacerations, decreases overall lacerations), Operative vaginal delivery (i.e., forceps, vacuum), Prolonged second stage of labor (> 60 minutes), Immediate, unlimited access to all AFP content, Immediate, unlimited access to this issue's content, Immediate, unlimited access to just this article. The perineal skin is then closed using a running, subcuticular suture. A fourth-degree laceration is a tear in the area surrounding the vagina, the skin and muscles between the vagina and anus (perineal skin & perineal muscles), the anal sphincters (the muscles that surrounds your anus) and into the anus. The anal sphincter complex extends for a distance of 3 to 4 cm.6, The internal anal sphincter provides most of the resting anal tone that is essential for maintaining continence. The patient suffered no complications from this procedure. Aka: Perineal Laceration Repair, Episiotomy Repair, Obstetric Laceration Repair, Obstetrical Laceration, Female Perineal Laceration, First-degree Perineal Laceration, Second Degree Perineal Laceration, Third Degree Perineal Laceration, Fourth Degree Perineal Laceration, These images are a random sampling from a Bing search on the term "Perineal Laceration Repair." An episiotomy is a procedure that may be used to widen the vaginal opening in a controlled way. [3]A digital rectal examination should be done with any severe laceration to assess the integrity and tone of theanal sphincter.[3][4]. The written test is the same as the one used by Patel et al to evaluate residents' knowledge about fourth-degree laceration repair. 308. Intermediate repair code genitalia 12041 - 12047 Varies by code Use in conjunction with 11420 -11426 and 11620-11626 if layered closure required . One of the most common surgical procedures for an obstetrician is primary repair of a perineal laceration, whether spontaneous or after episiotomy. A Cochrane review demonstrated that liberal use of episiotomy does not reduce the incidence of anal sphincter lacerations and is associated with increased perineal trauma.18 [Evidence level A, systematic review of RCTs] A meta-analysis of eight randomized trials of vacuum extraction versus forceps delivery demonstrated that one sphincter tear would be prevented for every 18 women delivered with vacuum rather than forceps.19 [Evidence level B, systematic review of lower quality RCTs]. A Cochrane review demonstrated that digital perineal self-massage starting at 35 weeks' gestation reduces the rate of perineal lacerations in primiparous women with a number needed to treat of 15 to prevent one laceration.5 Because the review included fewer than 2,500 patients, reductions could not be demonstrated for specific laceration grades. Perineal lacerations are defined by the depth of musculature involved, with fourth-degree lacerations disrupting the anal sphincter and the underlying rectal mucosa and first-degree lacerations having no perineal muscle involvement. Fourth degree perineal tears; Obstetrical anal sphincter injury (OASIS); Vaginal birth, Anal sphincter, Postpartum urinary retention. Identify the anatomy. There is no consensus on the best ways to prevent or reduce the severity of lacerations. A Cochrane review demonstrated that digital perineal self-massage starting at 35 weeks' gestation reduces the rate of perineal lacerations in primiparous women with a number needed to treat of 15 to prevent one laceration. Identify multiple different perineal lacerations. A vaginal tear (perineal laceration) is an injury to the tissue around your vagina and rectum that can happen during childbirth. After repair of a third- or fourth-degree laceration, we include several weeks of therapy with a stool softener, such as docusate sodium (Colace), to minimize the potential for repair breakdown from straining during defecation. Fourth degree tears are full-thickness tears through the internal anal sphincter (IAS) and the anal epithelium. Background. If the apex is too far into the vagina to be seen, the anchoring suture is placed at the most distally visible area of laceration, and traction is applied on the suture to bring the apex into view. Management of third and fourth degree perineal tears following vaginal delivery; RCOG guideline no. 2010. pp. StatPearls Publishing, Treasure Island (FL). 1 This was equivalent to a rate of 358 perineal lacerations for vaginal birth per 10,000 hospitalisations in 2015-16.1 Third and fourth degree perineal lacerations cause persistent and distressing 1194-8. Copyright 2023 American Academy of Family Physicians. (C) The internal anal sphincter should be properly identified and repaired as a separate layer. [1][3]Most perineal lacerations that occur in a vaginal delivery can be classified as first- or second-degree. If the laceration has separated the rectovaginal fascia from the perineal body, the fascia is reattached to the perineal body with two vertical interrupted 3-0 polyglactin 910 sutures (Figure 8). In a fourth-degree laceration, the rectal mucosa is reapproximated starting at 1 cm above the apex of the laceration. Proper technique for repair, as well as each step of the repair, is demonstrated, including repair of: the anal epithelium with a second imbricating layer through the anorectal muscularis and submucosa . Risk factors for perineal lacerations include nulliparity, operative vaginal delivery, midline episiotomy, Asian race, and increased fetal weight. Please do the following: 1. A midline episiotomy increases the risk for extension of the episiotomy into the anal sphincter. Muscles of perineal body. Sultan, AH, Thakar, R. Lower genital tract and anal sphincter trauma. [12], Delayed or immediate pushing after a woman reached ten centimeters of dilation showed no difference in the incidence of perineal lacerations. Local perineal cooling during the first three days after perineal repair reduces pain. Residual Defects of the Anal Sphincter Complex Following Primary Repair of Obstetrical Anal Sphincter Injuries at a Large Canadian Obstetrical Centre. Close the rectal mucosa- If possible knots on the rectal side of the closure is preferable. A single dose of prophylactic antibiotics, such as a second-generation cephalosporin, at the time of the repair is reasonable for women who sustain a 3rd or 4th degree laceration. Approximately 3% of lacerations involve clinically evident obstetric anal sphincter injuries, doubling the risk of fecal incontinence at five years postpartum.3,4 These lacerations are further classified by the extent of anal sphincter injury (Table 1).1, Less than 50% external anal sphincter involvement, More than 50% external anal sphincter involvement. (B) The torn anal mucosa is repaired using a running stitch, but interrupted stitches are also acceptable. Effect of perineal massage on the rate of episiotomy and perineal tearing.

Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.35 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. Minimal skin edge debridement was required. Perineal lacerations should be repaired immediately after child birth to reduce blood loss and also reduce the chance of infection. A correct repair is required to avoid improper healing, as a persistent defect in the external anal sphincter after delivery can increase the risk of complications and worsening of symptoms following subsequent vaginal deliveries. Previous perineal tears increase the risk of another, Encourage perineal massage weeks before delivery, The woman should be placed on complete bed rest, She should take a low residue diet and prune juice for at least five days. We recommend the use of sitz baths and an analgesic such as ibuprofen.

You must log in or register to reply here. *** 3-0 Nylon interrupted sutures were placed. Repair of a second-degree laceration (Figure 3) requires approximation of the vaginal tissues, muscles of the perineal body, and perineal skin. Women reported that self-massage was initially uncomfortable, unpleasant, and even painful, but nearly 90% would recommend the technique to others.6, Studies of prevention during delivery have focused on prevention of obstetric anal sphincter injuries. You will then identify and grasp the torn edges of the external anal sphincter capsule with Allis clamps and perform a repair as for a third-degree laceration. Continuous suturing of second-degree perineal tears reduces short-term pain and pain medication use. vol. Demirel G, Golbasi Z. A fourth-degree tear is also called fourth-degree laceration.
