To compare the continuous knotless technique of perineal repair with the interrupted method after spontaneous vaginal birth
                A randomized controlled trial.
                Canadian Task Force Classification I.
                This study was undertaken in a university hospital with more than 2200 deliveries per year. The static population of this district includes a wide range of socioeconomic classes and is predominately white.
                From May 1 to November 19, 2003, 214 primiparous women with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous knotless technique (CKT; n=107) or the interrupted technique (IT; n=107) suturing method.
                The interrupted technique (IT) involves placing 3 layers of sutures whereas the continuous knotless technique (CKT) involves reapproximating vaginal trauma, perineal muscles, and skin with a loose, continuous, nonlocking technique.
                The primary outcomes of the study were perineal pain (evaluated by visual analogue scale) at 48 hours and day 10 and dyspareunia 3 months after delivery. Secondary outcomes included suture removal, wound dehiscence, analgesia use up to 48 hours, and satisfaction with repair established at 3 and 12 months after childbirth. At day 10, 19 women had dropped out of the study. Significantly fewer women reported pain at 10 days with the CKT than with the IT (32.3% vs 60.4%; p<.001). Analgesia use up to 48 hours postpartum was less in the CKT group than in the IT group (33.6% vs 54.2%; p<.05). No difference was found in superficial dyspareunia at 3 months for the CKT versus the IT group.
                The use of a continuous knotless technique for perineal repair is associated with less short-term pain than techniques with interrupted sutures. To evaluate a policy of two stage postpartum perineal repair leaving the skin unsutured.
                A stratified randomised controlled trial using a 2 x 2 factorial design.
                The maternity unit at Ipswich Hospital NHS Trust, a district general hospital, between 1992 and 1994.
                1780 women requiring surgical repair of episiotomy or first or second degree tear following a spontaneous or simple instrumental delivery.
                A policy of two-stage perineal repair leaving skin unsutured was compared with a policy of three stage repair including skin closure with interrupted or subcuticular sutures. Both groups were assessed by a research midwife, blind to the allocation, completing questionnaires at 24 to 48 hours and 10 days postpartum, and by self-completed questionnaires at three months after birth.
                1. 24 to 48 hours postpartum: perineal pain; healing; 2. 10 days postpartum: perineal pain, healing and removal of sutures; 3. three months postpartum: perineal pain, removal of sutures, resuturing, dyspareunia, and failure to resume pain-free intercourse.
                Completed questionnaires were returned for 99% of women at both 24 to 48 hours and ten days and by 93% of women three months postpartum. No differences were detected in perineal pain at 24 to 48 hours (62% vs 64%; RR 0.96, 95% CI 0.90-1.03; 2P = 0.3) and 10 days (25% vs 28%; RR 0.90, 95% CI 0.77-1.06; 2P = 0.2). Significantly fewer women allocated to two-stage repair reported tight stitches at ten days (14% vs 18%; RR 0.77, 95% CI 0.62-0.96, 2P = 0.02); similar numbers of repairs were judged to be breaking down (five compared with seven women). At three months postpartum fewer women allocated to the two-stage repair reported perineal pain and more had resumed pain-free intercourse. Amongst women who had resumed intercourse there was a significant difference in dyspareunia (15% vs 19%; RR 0.80, 95% CI 0.65-0.99; 2P = 0.04). Significantly fewer women in the two-stage repair group (7% vs 12%; RR 0.61, 95% CI 0.45-0.83; 2P = < 0.01) reported removal of suture material. Four women in the two-stage repair group had required resuturing, compared with nine allocated to the three-stage repair.
                Two-stage repair of perineal trauma leaving the skin unsutured appears to reduce pain and dyspareunia three months postpartum. There are no apparent disadvantages, in particular no evidence of an increased risk of breakdown of the repair and resuturing. We set out to compare a policy of two-layered postpartum perineal repair leaving the skin unsutured with a policy of three-layered repair, which involved skin closure. Parturients who sustained a second-degree tear or an episiotomy in four Nigerian centers were randomised to have either a two-layered repair (417 women) or a three-layered repair (406 women). Fewer women in the two-layered group reported perineal pain at 48 hours (57% vs. 65%, relative risk [RR] 0.87, 95% confidence interval [CI] 0.78-0.97) and 14 days postpartum (22% vs. 28%, RR 0.77, CI 0.61-0.98). The two-layered repair was also associated with reduced risk of suture removal (6% vs. 10%, RR 0.62, CI 0.39-0.99), and less superficial dyspareunia at 3 months (6% vs. 12%, RR 0.52, CI 0.33-0.81). The rates of wound healing were similar between the two groups. Leaving the skin unsutured during postpartum perineal repair reduces perineal pain and dyspareunia. Commonly used suture materials and techniques for perineal repair following vaginal delivery were compared in a randomized controlled trial involving 1574 women. Three comparisons were made using a modified factorial design. In the comparison of teflon-coated polyglycolic acid (Dexon plus) with chromic catgut for repair of the vagina and deep perineal tissues there was no clear difference other than less short-term analgesia being required in association with polyglycolic acid. Outcome was also similar after skin repair with either polyglycolic acid or chromic catgut or silk, although silk repair required more packets of material and was associated with delay in resuming sexual intercourse; polyglycolic acid was more likely to need removal than chromic catgut but it appeared to reduce the need for resuturing. There was no clear difference between continuous subcuticular and interrupted transcutaneous sutures for repair of perineal skin. The study aimed to highlight any differences between the sequelae of episiorrhaphy performed using the Blair-Donatti and Guilmen-Pontonnier techniques.
                A total of 202 pregnant women were recruited in the Obstetrics Ward of Codogno Civic Hospital in 1994 and 1995. Subjects were randomly divided into two groups matched for socioeconomic status, age and parity (group A: Guilmen-Pontonnier suture, group B: Blair-Donatti suture). The following parameters were evaluated: pain twenty-four hours, sixty-six hours and one, two and three months after labour, pain during sexual relations, the onset of infection, hematoma, dehiscence of the wound, and lastly the cosmetic results.
                No significant differences were found between the parameters examined in both groups, barring the improved cosmetic result in group A. To compare different repair techniques and different suture materials for episiotomy.
                160 women having vertex delivery with right-mediolateral episiotomy were randomly allocated to four groups. In the groups where continuos technique was performed, vaginal mucosa, perineal muscles and the skin were sutured continuously. In the groups of interrupted technique, vaginal mucosa was sutured with continuous sutures, then muscle layers and skin were closed by interrupted sutures. Two different types of synthetic absorbed suture material were used: monofilament type is in form of polyglycolide-co-caprolactone and multifilament one is polyglactin 910-Rapide. Perineal pain during different activities on the first and tenth day postpartum and also during sexual intercourse 6 weeks after the delivery was questioned by visual analogous scale (VAS). Furthermore, repair time, amount of suture and episiotomy complications were investigated in each groups.
                On the first day after delivery, the perineal pain scores, the repair time, the amount of suture were statistically less in the continuous technique groups. The differences between the pain at tenth day and during sexual intercourse 6 weeks after the delivery were statistically same.
                The continuous suturing techniques for episiotomy closure, compared to interrupted methods, are associated with less short-term pain, are quicker and also need less suture material. Trauma to the perineum is a serious and frequent problem after childbirth, with about 350000 women each year in the UK needing sutures for perineal injury after spontaneous vaginal delivery, and many millions more worldwide. We compared the continuous technique of perineal repair with the interrupted method, and the more rapidly absorbed polyglactin 910 suture material with the standard polyglactin 910 material.
                1542 women who had a spontaneous vaginal delivery with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous (n=771) or interrupted (771) suturing method, and to either the more rapidly absorbed polyglactin 910 suture material (772) or standard polyglactin 910 material (770). Primary outcomes were pain 10 days after delivery and superficial dyspareunia 3 months postpartum. Analysis was by intention to treat.
                At day 10, three women had dropped out of the study. Significantly fewer women reported pain at 10 days with the continuous technique than with the interrupted method (204/770 [26.5%] vs 338/769 [44.0%], odds ratio 0.47, 95% CI 0.38-0.58, p<0.0001). Occurrence of pain did not differ significantly between groups assigned the more rapidly absorbed material or standard material (256/769 [33.3%] vs 286/770 [37.1%], 0.84, 0.68-1.04, p=0.10). Women reported no difference in superficial dyspareunia at 3 months for the continuous vs the interrupted method (98/581 [16.9%] vs 102/593 [17.2%], 0.98, 0.72-1.33, p=0.88) or the more rapidly absorbed versus standard material (105/586 [17.9%] vs 95/588 [16.2%], 1.13, 0.84-1.54, p=0.42). Suture removal was done less with the more rapidly absorbed material than with standard suture material (22/769 [3%] vs 98/770 [13%], p<0.0001), and with the continuous versus interrupted method (24/770 [3%] vs 96/769 [12%], p<0.0001).
                A simple and widely practicable continuous repair technique can prevent one woman in six from having pain at 10 days. Also, the more rapidly absorbed polyglactin 910 material obviates need for suture removal up to 3 months postpartum for one in ten women sutured. The aim was to compare healing and perineal pain with the use of continuous and interrupted suture techniques in women after normal delivery. A randomized controlled trial was carried out at a hospital birth center in Itapecirica da Serra, Sao Paulo, Brazil. A total of 61 women participated with episiotomy or second degree perineal tear, allocated in two groups according to the continuous (n=31) or interrupted (n=30) suture techniques. The main outcomes evaluated were edema, ecchymosis, hyperemia, secretion, dehiscence, fibrosis, frequency and degree of pain (evaluated by numerical scale from 1 to 10). Data were collected during hospitalization and after discharge (four and 41 days after birth). Healing occurred by first intention in 100% of cases in both suture techniques. There were no statistically significant differences for the occurrence of morbidities, except for perineal pain due to palpation at four days after delivery, which was more frequent among women with interrupted suture. Polyglycolic acid sutures (Dexon) were compared to chromic catgut sutures in episiotomy repair. When polyglycolic acid sutures were used, the degree of postpartum perineal pain was approximately half as great, and the incidence of dehiscence of episiotomy was 3--5 times greater in the chromic catgut group. The cosmetic results 3 months postpartum were clearly better by using Dexon sutures, especially when the perineal skin was closed by a continuous intracutaneous suture. To evaluate the repair techniques of continuous and interrupted methods for episiotomy or perineal tears.
                A randomised controlled trial.
                The Hospital Universitario Principe de Asturias, a state hospital belonging to the community of Madrid.
                Four hundred forty-five women who had undergone vaginal deliveries with episiotomies or second-grade tearing of the perineum between September 2005 and July 2007.
                One group was repaired with continuous, nonlocking sutures involving the vagina, perineum, and subcutaneous tissues. The other group had continuous, locking sutures of the vagina, interrupted sutures in the perineal muscles, and interrupted transcutaneous sutures. The threads used for stitching were identical in both groups.
                The participants were questioned regarding the sensation of pain and the use of painkillers on the second and the tenth days, and 3 months postpartum.
                When comparing the group with continuous suture to the group with interrupted sutures, the differences included less repair time (1 minute; P= 0.017) and less suture material used (relative risk [RR], 3.2, 95% CI: 2.6-4.0). The comparison of pain on the second and tenth days, and 3 months postpartum were not statistically different between the two techniques (RR, 1.08, 95% CI: 0.74-1.57; RR, 0.96, 95% CI: 0.59-1.55; and RR, 0.68, 95% CI: 0.19-2.46, respectively).
                Although we did not demonstrate that one technique was better than the other in the incidence of pain in the short or long term, we showed that episiotomy and perineal tear repairs with continuous suturing were quicker and used less suture material without an increase in complication than interrupted suturing. nan Three methods of episiotomy repair were randomly assigned after 900 consecutive deliveries. The three procedures were: (1) continuous No. 00-plain catgut in the vagina; No. 00-plain catgut interrupted stitches in the perineal muscles and fascia, and No. 00-nylon interrupted stitches in the skin. (2) The same technique as in (1), but with No. 0-polyglycolic acid (Dexon) in all layers. (3) The suture material as in (2), but used with a subcuticular technique. The women treated with method 3 reported statistically significant less pain and disabilities in the early puerperium. Three months after delivery 262 women (33%) still had perineal complaints which could be directly related to the episiotomy in 25% (8% of total number). The group treated with method 3 had the best long-term results and we conclude that the subcuticular technique using polyglycolic acid should be the method of choice. To compare a continuous suture technique with interrupted stitches using inverted knots for postpartum perineal repair of second-degree lacerations and episiotomies.
                A double-blind randomised controlled trial.
                A Danish university hospital with more than 4800 deliveries annually.
                A total of 400 healthy primiparous women with a vaginal delivery at term. METHOD Randomisation was computer-controlled. Structured interviews and systematic assessment of perineal healing were performed by research midwives blinded to treatment allocation at 24-48 hours, 10 days and 6 months postpartum. Pain was evaluated using a visual analogue scale and the McGill Pain Questionnaire. Wound healing was evaluated using the REEDA scale and by assessment of gaping wounds >0.5 cm. Analysis complied with the intention-to-treat principle.
                The primary outcome was perineal pain 10 days after delivery. Secondary outcomes were wound healing, patient satisfaction, dyspareunia, need for resuturing, time elapsed during repair and amount of suture material used.
                A total of 400 women were randomised; 5 women withdrew their consent, leaving 395 for follow up. The follow-up rate was 98% for all assessments after delivery. No difference was seen in perineal pain 10 days after delivery. No difference was seen in wound healing, patient satisfaction, dyspareunia or need for resuturing. The continuous suture technique was significantly faster (15 versus 17 minutes, P = 0.03) and less suture material was used (one versus two packets, P < 0.01).
                Interrupted, inverted stitches for perineal repair leaving the skin unsutured appear to be equivalent to the continuous suture technique in relation to perineal pain, wound healing, patient satisfaction, dyspareunia and need for resuturing. The continuous technique, however, is faster and requires less suture material, thus leaving it the more cost-effective of the two techniques evaluated.
The continuous suturing techniques for perineal closure, compared with interrupted methods, are associated with less short-term pain, need for analgesia and suture removal. Furthermore, there is also some evidence that the continuous techniques used less suture material as compared with the interrupted methods (one packet compared to two or three packets, respectively).
