RESUMO

BACKGROUND: Surgical glue has been used in several body tissues, including perineal repair, and can benefit women. OBJECTIVES: To evaluate the effectiveness of n-butyl-2-cyanoacrylate surgical glue compared to the polyglactin 910 suture in repairing first- and second-degree perineal tears and episiotomy in vaginal births. DESIGN: A parallel randomised controlled open trial. SETTING: Birth centre in Itapecerica da Serra, São Paulo, Brazil. PARTICIPANTS AND METHODS: The participants were 140 postpartum women allocated into four groups: two experimental groups repaired with surgical glue (n = 35 women with a first-degree tear; n = 35 women with a second-degree tear or episiotomy); two control groups sutured with thread (n = 35 women with a first-degree tear; n = 35 women with a second-degree tear or episiotomy). The outcomes were perineal pain and the healing process. Data collection was conducted in six stages: (1) up to 2 h after perineal repair; (2) from 12 to 24 h postpartum; (3) from 36 to 48 h; (4) from 10 to 20 days; (5) from 50 to 70 days; and (6) from 6 to 8 months. ANOVA, Student's t, Monte Carlo, x-square and Wald tests were used for the statistical analysis. RESULTS: One hundred forty women participated in the first three stages, 110 in stage 4, 122 in stage 5, and 54 in stage 6. The women treated with surgical glue had less perineal pain (p ≤ 0.001). There was no difference in the healing process, but the CG obtained a better result in the coaptation item (p ≤ 0.001). CONCLUSIONS: Perineal repair with surgical glue has low pain intensity and results in a healing process similar to suture threads.

RESUMO

Background: Perineal tears in vaginal birth are highly prevalent and may be related to physical and psychological trauma. Surgical glues are an alternative repair method to avoid the pain that may be caused by perineal repairs with sutures. Objective: To evaluate the effectiveness of surgical adhesive glue in reducing perineal pain when compared to sutures in first-degree perineal tears resulting from vaginal birth. Design: Open-label parallel-group randomised controlled trial. Setting: An alongside birth centre in Sao Paulo, Brazil. Participants: 84 intrapartum women with first-degree perineal tears needing repair. Methods: In the experimental group (n = 42), the perineal tears were repaired with Epiglu® surgical glue (ethyl-2-cyanoacrylate); in the control group (n = 42), the tears were repaired with Vicryl Rapide® (polyglactin 910) sutures. The primary outcome was the intensity of perineal pain after birth measured by a numeric pain rating scale ranging from 0 to 10 points. The secondary outcomes were healing, measured by the "Redness, Oedema, Ecchymosis, Discharge, and Approximation" scale; women's satisfaction with the perineal repair, measured by a visual analogue scale; and the time necessary to complete the repair. Data were collected during postpartum hospitalisation and 10-20 days after discharge, from December 2020 to May 2021. Data were analysed using bivariate analysis and linear models by intention-to-treat. Results: 36-48 h after birth, the mean of perineal pain was 0.2 (95% Confidence Interval [CI] 0.1-0.8) in the experimental group and 0.9 (95% CI 0.5-1.5) in the control group; the perineal healing score was 0.7 (95% CI 0.4-1.2) and 0.8 (95% CI 0.5-1.2), in the experimental and control groups, respectively; satisfaction was higher among women in the experimental group (88.1% versus 83.3% in the control group). After discharge, the mean of perineal pain was 0.1 (95% CI 0.0-0.5) in the experimental group and 1.4 (95% CI 0.8-2.2) in the control group; the perineal healing score was 0.0 (95% CI 0) and 1.0 (95% CI 0.7-1.3) in the experimental and control groups, respectively. Satisfaction was higher in the experimental group (94.9% versus 75.0%). The longitudinal analysis showed statistically significant differences between the groups regarding perineal pain and women's satisfaction. The average time necessary for perineal repair was 6.0 (95% CI 4.7-8.7) minutes in the experimental group and 9.7 (95% CI 8.3-11.5) in the control group (p < 0.001). Conclusions: Surgical glue resulted in less perineal pain, faster repair, and greater satisfaction than perineal sutures after birth. The healing process was similar in both cases. Tweetable abstract: Surgical glue was less painful and promoted greater satisfaction after birth compared to sutures in women with first-degree perineal tears.

RESUMO

ABSTRACT: A variety of periodontal plastic surgery techniques have been proposed to correct aesthetic and functional problems caused by gingival recession, with root coverage using connective tissue grafts being the one most commonly performed. These surgeries, however, are partially dependent on tissue graft stability. In this case series, we describe the use of a tissue adhesive (cyanoacrylate) as a solution for graft stabilization. Two patients with Cairo's type 1 gingival recession were treated with an envelope technique using connective tissue graft stabilized with cyanoacrylate alone. The results were a faster procedure and complete root coverage, even after 5 years of follow-up. Our findings suggest that cyanoacrylates can be an alternative to standard graft stabilizing procedures, leading to a stable root coverage in RT1 recessions.

Abstract Objective To describe the use of surgical glue to repair perineal trauma during normal delivery. Methods This is a case series study, which was carried out in three moments (up to 2 hours, 12-24 hours and 36-48 hours after delivery) in Itapecerica da Serra, SP. Women who had a normal delivery with perineal trauma with a suture (first or second degree laceration and episiotomy) were included. Perineal trauma was repaired exclusively with Glubran-2® surgical glue. Perineal pain intensity (11-point Visual Numeric Scale), healing process (15-point REEDA scale), satisfaction with repair (5-point Likert scale) were assessed. Data were analyzed in a descriptive and inferential way comparing the three moments. Results The technique of applying the glue and the required amount were defined in a sample of 19 women. Of these, 78.9% had first-degree lacerations, 15.8%, second-degree lacerations and 5.3%, episiotomy. The outcomes at moments 1, 2 and 3 were absence of pain (73.6%, 94.7% and 89.4%), score ≤1 on the REEDA scale (94.7%, 78.9% and 84, two%); 100% were satisfied with the repair at all times. There was no difference by the Friedman test for pain and satisfaction. The healing process showed a difference, but without confirmation in the hoc post-test. Conclusion The glue application proved to be viable for assessment in a larger sample of women, as the results suggest good acceptance by women and low or no pain, adequate healing and high satisfaction with the repair in the first 48 hours after delivery.

RESUMO

RESUMEN Introducción: el Tisuacryl es un biomaterial de gran efectividad como apósito periodontal en papilectomías, gingivectomías y gingivoplastias. Objetivo: determinar la efectividad del Tisuacryl con respecto al cemento quirúrgico o Quirucem, usados como apósito periodontal en cirugías periodontales. Métodos: estudio observacional analítico de casos y controles en 60 pacientes con diagnóstico de gingivitis crónica fibrosa y fibroedematosa desde septiembre de 2016 a junio de 2017. Se realizó examen físico, confección de historia clínica de periodoncia, tratamiento periodontal y selección de pacientes con necesidad de tratamiento quirúrgico. Se utilizaron medidas de resúmenes para variables cualitativas como el porcentaje y para variables cuantitativas como la media y la desviación estándar. Se empleó el test estadístico prueba de Chi cuadrado con nivel de significación de &= 0.05 para la comparación de los grupos con diferentes modalidades de tratamiento. Resultados: el total de los pacientes tratados con Tisuacryl expresaron comodidad con el uso de este y no se produjo acúmulo de placa dentobacteriana. Solo el 30 % presentó enrojecimiento a los siete días, pero a los 15 se constató cicatrización total de la herida. Con Quirucem existieron todos los síntomas y signos estudiados y en todos los casos el enrojecimiento; más de la mitad presentó incomodidad en la evolución y el 40 % de los casos a los 15 días continuaban sin cicatrizar totalmente. Conclusiones: el Tisuacryl resultó más efectivo con respecto al Quirucem considerando el menor tiempo de cicatrización, mayor comodidad y estética en los pacientes.

ABSTRACT Introduction: Tisuacryl is a highly effective biomaterial as a periodontal dressing in papillectomies, gingivectomies and gingivoplasties. Objective: to determine the effectiveness of Tisuacryl with respect to surgical cement or Quirucem, used as a periodontal dressing in periodontal surgeries. Methods: observational analytical study of cases and controls in 60 patients with the diagnosis of chronic fibrous and fibro-edematous gingivitis from September 2016 to June 2017. Physical examination, periodontal history, periodontal treatment and selection of patients in need of surgical treatment were performed. Summary measures were used for qualitative variables, such as percentage and for quantitative variables such as mean and standard deviation. The chi-square statistical test with a significance level of &= 0.05 was used to compare the groups with different treatment modalities. Results: all patients treated with Tisuacryl expressed comfort with its use and no accumulation of dentobacterial plaque occurred. Only 30 % had redness at seven days, but at 15 days the wound was completely healed. With Quirucem all the symptoms and signs studied were present along with redness in all cases; more than the half of patients complained of discomfort during evolution and 40 % of the cases at 15 days remained totally unhealed. Conclusions: Tisuacryl was more effective than Quirucem considering the shorter time of cicatrization, greater comfort and better aesthetics results in patients.

RESUMO

The focus of this study was to test the hypothesis that there would be no difference between the biocompatibility of cyanoacrylate-based adhesives in rat subcutaneous tissues. In total, 60 male Wistar rats were used, and divided into four groups (n = 15): Group C (control, PVA-polyvinyl alcohol sponge), Group NO (N-butyl-2-octylcyanoacrylate), Group NH (n-hexyl-cyanoacrylate), and Group EC (Ethyl-cyanoacrylate). The animals were sacrificed after time intervals of 7, 15, and 30 days and tissues were analyzed under optical microscope as regards the events of inflammatory infiltrate, edema, necrosis, granulation tissue, giant cells, young fibroblasts, and collagen formation. The results were statistically analyzed by the Kruskal-Wallis and Dunn tests (p < .05). Significant inflammatory infiltrate was shown for all the adhesives in the time intervals of 7 (p = .004) and 15 days (p = .003). In the time interval of 30 days, moderate inflammatory infiltrate was observed in Groups NH and EC, with significant difference from Control (p = .001). The quantity of collagen fibers in all the experimental groups showed significant difference compared with Control in the time intervals of 7 (p = .002) and 15 days (p = .001), at 30 days only Group EC showed a smaller quantity of collagen fibers in comparison with Control (p = .001). The hypothesis was rejected. The adhesive N-butyl-2-octylcyanoacrylate had less influence on the inflammatory intensity of multinucleated giant cells. Ethyl-cyanoacrylate demonstrated the lowest level of biocompatibility among the adhesives, but its use in clinical practice may be promising for coaptation of smaller edges of superficial tissue. Surgical adhesives were shown to be feasible for clinical use in substitution of conventional suturing. Ethyl-cyanoacrylate should be used with caution due to its greater influence on tissues.

RESUMO

RESUMO Objetivo: avaliar o perfil de segurança e os resultados estéticos do 2-octilcianoacrilato versus sutura intradérmica com fio de nylon em cirurgias mamárias. Métodos: ensaio clínico randomizado, aberto, que avaliou a ocorrência de complicações, como deiscência, hematoma, infecção e reações alérgicas após o uso do 2-octilcianoacrilato ou do fio de nylon. Também foi analisado o tamanho das incisões, o tempo de fechamento da pele e o tempo cirúrgico total. O resultado estético foi avaliado após 40 e 180 dias da cirurgia, por meio da largura média da ferida operatória e por avaliação subjetiva conceitual (ótimo, bom, razoável ou ruim). Resultados: foram incluídas 79 pacientes, sendo 37 no grupo 2-octilcianoacrilato e 42 no grupo de sutura com fio de nylon. O estudo foi interrompido antes do término do recrutamento dos pacientes pela ocorrência de maior número de deiscências no grupo do adesivo (OR: 11,42; IC95%: 1,36-96,02; p=0,007). Em relação às demais complicações analisadas, ao tempo cirúrgico e ao resultado estético no pós-operatório, não se observaram diferenças significativas entre os grupos. A média do tamanho da ferida operatória foi maior no grupo do adesivo em relação ao grupo da sutura, mas não houve correlação entre o tamanho da ferida e o maior número de deiscências. Conclusão: o 2-octilcianoacrilato apresentou maior risco de deiscência em relação à sutura intradérmica, com resultados estéticos equivalentes.

ABSTRACT Objective: to evaluate the safety profile and aesthetic results of 2-octyl-cyanoacrylate versus intradermal nylon suture in breast surgeries. Methods: an open-label, randomized, clinical trial evaluating the occurrence of complications, such as dehiscence, hematoma, infection, and allergic reactions after the use of 2-octyl-cyanoacrylate or nylon thread. The size of the incisions, skin closure time, and total surgical time were also analyzed. The aesthetic outcome was evaluated at 40 and 180 days after surgery, by means of the average width of the surgical wound and by subjective conceptual assessment (optimal, good, reasonable, or poor). Results: 79 patients were included: 37 in the 2-octyl-cyanoacrylate group and 42 in the nylon suture group. The study was stopped before the end of patient recruitment due to the occurrence of a greater number of dehiscences in the adhesive group (OR: 11.42; 95%CI: 1.36-96.02; p=0.007). Regarding the other analyzed complications, the surgical duration and postoperative aesthetic result, no significant differences were observed between the groups. The mean operative wound size was greater in the adhesive group than in the suture group, but there was no correlation between wound size and the largest number of dehiscences. Conclusion: while the cosmetic outcomes with the two techniques were similar, there was a greater risk of dehiscence with the use of 2-octyl-cyanoacrylate compared to intradermal suturing.
