Cyanoacrylate tissue adhesive versus silk sutures for mandibular third molar surgery: a systematic review and meta-analysis.

OBJECTIVE: Cyanoacrylate tissue adhesive has been presented as an alternative to sutures and several studies have compared them. The objective of this meta-analysis was to evaluate the effect of cyanoacrylate tissue adhesive on postoperative pain and swelling, following mandibular third molar surgery. MATERIALS AND METHODS: Database search was conducted in MEDLINE/PubMed and Scopus, along with extensive search in the grey literature, including randomized and non-randomized clinical trials that applied cyanoacrylate adhesive for closing mandibular third molar surgical sites and compared it with silk sutures, assessing postoperative pain and swelling. The search ended on September 22, 2023. RESULTS: Of 886 identified articles, six were included and meta-analyzed. Applying cyanoacrylate demonstrated a reduction in the overall postoperative pain (SMD = -0.57, 95% CI -1.00 to -0.15, p = 0.009). A similar outcome was noted when pain was evaluated on the first and last postoperative days, based on controlled clinical trials (SMD = -0.47, 95% CI -0.92 to -0.03, p = 0.04), and randomized trials (SMD = -0.97, 95% CI -1.31 to -0.62, p < 0.00001). Patients/sides received cyanoacrylate showed a decrease in postoperative swelling (SMD = -0.26, 95% CI -0.51 to -0.01, p = 0.04). Following the GRADE rating system, the quality of evidence on pain and swelling was judged as moderate and low, respectively. CONCLUSIONS: The use of cyanoacrylate adhesive may offer benefit in reducing postoperative pain and swelling following mandibular third molar surgery. Nevertheless, this should be further investigated, considering the low number of included reports. CLINICAL RELEVANCE: The current results could help clinicians who perform this procedure to manage postoperative pain and swelling more effectively.

Cyanoacrylate versus suture as flap closure methods in mandibular third molar surgery: a split-mouth randomized controlled clinical study.

BACKGROUND: Sutures have been the standard flap closure method of choice following mandibular third molar surgery but can lead to some complications. Tissue adhesives, including cyanoacrylate, have emerged as alternative flap closure method in this surgery to overcome such drawbacks. However, limited clinical trials can be found. Therefore, the aim of this clinical study was to compare two methods of flap closure in mandibular third molar surgery, cyanoacrylate and 4/0 silk sutures, by assessing post-operative outcome measures (pain, swelling, trismus, and healing) and patient-reported outcome measures (PROMs). MATERIAL AND METHODS: A randomized split-mouth clinical trial was designed, in which mandibular third molar (M3M) extractions were performed, where the control side flap was closed with 4/0 silk sutures and the test side flap with cyanoacrylate. Swelling, pain, trismus, healing, and PROMs were recorded post-operatively. These variables were analyzed by means of the nonparametric Mann-Whitney U test, using SPSS statistical software version 28.0.0 (IBM® SPSS®, Chicago, IL, USA). For all results, a 95% confidence interval was recorded (significance level p < 0.05, two-tailed). RESULTS: A total of 17 patients were recruited and 34 mandibular third molar extractions were performed. No statistically significant differences were found in terms of swelling, pain, trismus, healing, and PROMs between both groups (p<0.05). CONCLUSIONS: No statistically significant differences were found between flap closure with 4/0 silk sutures and cyanoacrylate, in terms of surgical post-operative outcomes and PROMs. However, further studies with larger sample sizes are required to be able to affirm it with greater certainty.

Treatment of gastric varices with cyanoacrylate complicated by systemic embolization.

Acute gastric variceal bleeding is a life-threatening condition that could be effectively treated with endoscopic cyanoacrylate injection diluted with lipiodol. The mixture acts as a tissue adhesive that polymerizes when in contact with blood in a gastric varix. This work reports a patient that presented to the emergency department with upper gastrointestinal bleeding due to acute variceal bleeding, who developed systemic embolization following cyanoacrylate injection therapy. This complication culminated in cerebral, splenic and renal infarctions with a fatal outcome. Systemic embolization is a very rare, but the most severe complication associated with endoscopic cyanoacrylate injection and should be considered in patients undergoing this treatment.

The Effectiveness of Cyanoacrylates versus Sutures for Mesh Fixation after Lichtenstein Repair (SCyMeLi STUDY) A Systematic Review and Meta-Analyze of Randomized Controlled Trials.

Background: Chronic postoperative inguinal pain (CPIP) is still the most frequent complication after open Lichtenstein repair and any strategy to reduce its incidence and implications is a step forward to better outcomes. Between the means of mesh fixation atraumatic glue fixation has been explored as such possibility. A meta-analysis of randomized controlled trials comparing the performance of cyanoacrylate glue versus sutures fixation was conducted. Methods: the meta-analysis was conducted according to the PRISMA guidelines. Randomized controlled trials (RCTs) published between January 2000 and December 2021 were searched for in MEDLINE, PubMed, Web of Science, and Google Scholars. The quality of RCTs and the potential risk of bias were assessed using MINORS criteria and the Cochrane risk of bias tool. Results: of 269 papers the meta-analysis was performed on 19 RCTs including 3578 patients. In the glue fixation group, the operation was shorter (mean pooled difference 6 minutes; SE = 0.47; 95% CI = - 6.77 - - 4.92; t test = -12.36; p 0.0001) and immediate postoperative pain was lower (2.37% vs 13.3%OR - 0.158; 95% CI = 0.064 0.386; p = 0.0001). There was no difference in terms of chronic pain, recurrence rate and wound events. Conclusion: glue fixation of mesh in elective Lichtenstein repair of inguinal hernia seems to be a valid choice for a painful and safe procedure without increasing risk of recurrence.

Glued suture-less peritoneum closure in laparoscopic inguinal hernia repair reduces acute postoperative pain.

Inguinal hernia repair is performed more than 20 million times per annum, representing a significant health and economic burden. Over the last three decades, significant technical advances have started to reduce the invasiveness of these surgeries, which translated to better recovery and reduced costs. Here we bring forward an innovative surgical technique using a biodegradable cyanoacrylate glue instead of a traumatic suture to close the peritoneum, which is a highly innervated tissue layer, at the end of endoscopy hernia surgery. To test how this affects the invasiveness of hernia surgery, we conducted a cohort study. A total of 183 patients that underwent minimally invasive hernia repair, and the peritoneum was closed with either a conventional traumatic suture (n = 126, 68.9%) or our innovative approach using glue (n = 57, 31.1%). The proportion of patients experiencing acute pain after surgery was significantly reduced (36.8 vs. 54.0%, p = 0.032) by using glue instead of a suture. In accordance, the mean pain level was higher in the suture group (VAS = 1.5 vs. 1.3, p = 0.029) and more patients were still using painkillers (77.9 vs. 52.4%, p = 0.023). Furthermore, the rate of complications was not increased in the glue group. Using multivariate regressions, we identified that using a traumatic suture was an independent predictor of acute postoperative pain (OR 2.0, 95% CI 1.1-3.9, p = 0.042). In conclusion, suture-less glue closure of the peritoneum is innovative, safe, less painful, and possibly leads to enhanced recovery and decreased health costs.

Successful Sealing of Post-COVID-19 Bronchopleural Fistula with Computed Tomography Scan-Guided Percutaneous Cyanoacrylate Glue Injection: A Case Series.

Bronchopleural fistula (BPF), a sinus tract between the bronchial system and the pleural space, is associated with COVID-19 and can lead to pneumothorax, which increases the mortality rate. Due to the analytical status of COVID-19 patients, sealing the BPF necessitates the least minimal invasive treatment. Herein, we demonstrated a technique of sealing post-COVID-19 BPF with direct injection of cyanoacrylate glue under the guidance of a computed tomography scan. Following glue injection, the BPF was completely sealed in all four patients. In conclusion, in COVID-19 patients with small and distal BPF, percutaneous glue injection is recommended for BPF closure.

Use of cyanoacrylate for the stabilization of tissues in root coverage procedures: A case series report with 5 years follow up

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.

Tratamiento de fístula enterocutánea combinando láser diodo y embolización / Combined treatment of enterocutaneous fistula with laser diode and embolization

INTRODUCCIÓN: El tratamiento delas fístulas enterocutáneas establecidas en pacientes multioperados es complejo y requiere de soluciones creativas. Presentamos la resolución de un caso con láser diodo y con cianoacrilatos. CASO CLÍNICO: Paciente de 15 años, diagnosticado a los 12 de colitis ulcerosa y sometido a pancolectomía con ileostomía urgente por brote refractario al tratamiento médico. Cinco meses después se realizó un descenso ileoanal con reservorio dejando ileostomía de protección, pero presentó un posoperatorio tórpido con infección pélvica, precisando dos nuevas laparotomías urgentes, para lavado y hemostasia. Seis meses después, se evidenció una estenosis de la anastomosis que se resolvió tras varias dilataciones, neumáticas bajo visión endoscópica y domiciliarias con tallos de Hegar. Un año después se cerró la ileostomía, presentando al mes una distensión abdominal y aparición de fístula en línea media abdominal, que pudo tutorizarse endoscópicamente, observando su origen en la anastomosis ileoanal. Se trató mediante sesiones de láser diodo, con mejoría parcial, aunque persistía la salida de gases. Un año después se embolizó implantando espirales de platino y cianoacrilatos diluidos con lipiodol, resolviéndose totalmente el cuadro. Transcurridos 17 meses de esta última intervención, el paciente se encuentra asintomático, con continencia fecal total diurna y nocturna, tres deposiciones al día y la fístula está totalmente cerrada. CONCLUSIÓN: El tratamiento con láser diodo, combinado con embolización con espirales de platino y cianoacrilatos, puede ser un tratamiento eficaz con baja morbilidad de las fístulas enterocutáneas establecidas

INTRODUCTION: Enterocutaneous fistula treatment in patients undergoing multiple surgeries is complex and requires creative solutions. We present the case of an enterocutaneous fistula managed with laser diode and cyanoacrylates. CLINICAL CASE: 15-year-old patient, diagnosed with ulcerative colitis at 12 years of age, undergoing full colectomy with urgent ileostomy as a result of a flare-up refractory to medical treatment. Five months later, an ileoanal pull-through with pouch was carried out, leaving a protection ileostomy in place. However, postoperative evolution was poor, with pelvic infection, so two further urgent open surgeries were required for lavage and hemostasis purposes. Six months later, anastomotic stricture was noted. It was healed following various pneumatic dilations under ultrasound vision and at-home dilations using Hegar dilators. One year following this, ileostomy was closed, but one month later, abdominal distension occurred. It was associated with a fistula in the abdominal midline, which could be endoscopically guided, with its origin being located at the ileoanal anastomosis. Laser diode sessions were applied for treatment purposes, with partial improvement, but still with gas emission. One year later, embolization was performed by placing platinum coils and lipiodol-diluted cyanoacrylates, and clinical signs disappeared. 17 months following this surgery, the patient has no symptoms, with full day and night fecal continence and 3 daily stools, and the fistula is completely closed. CONCLUSION: Combined treatment with laser diode and platinum coil and cyanoacrylate embolization proves effective in the management of enterocutaneous fistula, with low morbidity

Incisões cirúrgicas mamárias tratadas com 2-octilcianoacrilato versus sutura intradérmica com fio de nylon: ensaio clínico randomizado / Surgical breast incisions treated with 2-octyl-cyanoacrylate versus intradermal nylon suture: a randomized clinical trial

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.

Evaluation of tensile strength of tissue adhesives made of fibrin and cyanoacrylate used as reinforcement of colon suture in "ex vivo" swine

ABSTRACT Aim: To evaluate rupture pressures of tissue adhesives of cyanoacrylate (Omnex®) and fibrin (Evicel®), used as reinforcement in colonic suture from "ex vivo" swine. Methods: Surgical procedures were performed in the Surgical Technique Laboratory. From a division in segments of 10 cm of descending colon and sigmoid colon from three "ex vivo" female swine, Landrace breed, which were resected in less than six hours after the slaughter time, 30 segments were selected, 10 of each animal. They were stored in saline solution 0.9% at 36 °C, being randomly allocated in three groups (Control, Evicel and Omnex), each one containing 10 segments. Results: The lower and higher pressure values found in the groups Control, Evicel and Omnex were 36 mmHg and 41 mmHg, 70 mmHg and 90 mmHg, 90 mmHg and 120 mmHg, respectively. Containing statistical significance (p-value <0.0001) concerning the 2 to 2 comparisons (Control, Evicel and Omnex) with 95% trusting rate based on the application of the Turkey Method. Conclusion: One concludes that the use of tissue adhesives in anastomoses colonic in an experimental animal model of "ex vivo" swine increased the anastomoses rupture pressures. Among the tested adhesives, cyanoacrylate presented higher rupture pressure in relation to fibrin adhesive.

RESUMO Objetivo: Avaliar as pressões de ruptura dos adesivos teciduais de Cianoacrilato (Omnex®) e de Fibrina (Evicel®), usados como reforço em suturas colônicas de suínos "ex-vivo". Métodos: Os procedimentos cirúrgicos realizados foram realizados no Laboratório de Técnica Cirúrgica. A partir da divisão em segmentos de 10 cm do colo descendente e colo sigmoide de três suínas fêmeas ex-vivo, da raça Landrace, ressecados em tempo inferior a seis horas em relação ao momento do abate, foram selecionados 30 segmentos, 10 de cada animal. Foram armazenados em soro fisiológico 0,9% a 36 °C, alocando-se aleatoriamente esses segmentos em três grupos (Controle, Evicel e Omnex) com 10 segmentos cada. Resultados: Os menores e maiores valores pressóricos encontrados nos grupos Controle, Evicel e Omnex foram 36 mmHg e 41 mmHg, 70 mmHg e 90 mmHg, 90 mmHg e 120 mmHg, respectivamente. Com significância estatística (Valor-p < 0,0001) para as comparações 2 a 2 (Sutura, Evicel e Omnex) com um intervalo de confiança de 95% construído a partir da aplicação do método de Turkey. Conclusão: A partir desse estudo conclui-se que o uso de adesivos teciduais em anastomoses colônicas, em modelo experimental animal de suíno ex-vivo, aumentou as pressões de ruptura das anastomoses. Dentre os adesivos testados, o adesivo de Cianoacrilato apresentou maiores pressões de ruptura em relação ao adesivo de Fibrina.

Prevención de la hernia incisional mediante malla retrofascial fijada con cianoacrilato / Incisional hernia prevention using a cyanoacrilate-fixed retrofascial mesh

Introducción: La incidencia de hernia incisional en pacientes de riesgo (obesidad, cáncer, etc.) es elevada, incluso en cirugía laparoscópica. El objetivo de este estudio es evaluar la seguridad del empleo de mallas profilácticas retrofasciales fijadas con cianoacrilato en la incisión de asistencia en pacientes con sobrepeso sometidos a cirugía laparoscópica colorrectal. Métodos: Estudio prospectivo de cohortes, no aleatorizado, de pacientes sometidos a resección laparoscópica electiva por cáncer colorrectal entre enero de 2013 y marzo de 2016. Aquellos con índice de masa corporal superior a 25 kg/m2 fueron evaluados para implantar una malla profiláctica fijada con cianoacrilato (Histoacryl®) como refuerzo de la incisión de asistencia. Resultados: Se analizan 52 pacientes (índice de masa corporal medio: 28,4±2 kg/m2). En 15 pacientes se implantó una malla profiláctica. El tiempo de implante siempre fue inferior a 5 minutos. No hubo diferencias significativas en la tasa de infección de herida (12 vs. 10%). Ninguna malla requirió ser explantada. Aunque el seguimiento medio es menor (14,1±4 vs. 22,3±9 meses), no ha aparecido hernia incisional en el grupo malla. Por el contrario, en el grupo no malla se han observado una evisceración (2,7%) y 4 eventraciones de la incisión de asistencia (10,8%). No hubo diferencias significativas entre los grupos respecto a hernia incisional de trócar (6,6 vs. 5,4%). Conclusiones: La implantación de mallas profilácticas en pacientes con sobrepeso u obesidad sometidos a cirugía laparoscópica colorrectal es segura y parece reducir la tasa de eventraciones a corto plazo. La fijación con cianoacrilato es un método rápido que facilita el procedimiento sin complicaciones adicionales (AU)

Introduction: The rate of incisional hernia in high-risk patients (obesity, cancer, etc.) is high, even in laparoscopic surgery. The aim of this study is to evaluate the safety of the use of cyanoacrylate fixed prophylactic meshes in the assistance incision in overweight or obese patients undergoing laparoscopic colorectal surgery. Methods: A prospective, non-randomized cohort study of patients undergoing elective laparoscopic resection for colorectal cancer between January 2013 and March 2016 was performed. Those with a body mass index greater than 25 kg / m2 were evaluated to implant a prophylactic meshes fixed with cyanoacrylate (Histoacryl®) as reinforcement of the assistance incision. Results: 52 patients were analyzed (mean body mass index: 28.4±2 kg / m 2). Prophylactic meshes was implanted in 15 patients. The time to put the mesh in place was always less than 5minutes. There was no significant difference in wound infection rate (12% vs. 10%). No mesh had to be explanted. Although the mean follow-up was shorter (14.1±4 vs. 22.3±9 months), there were no incisional hernia in the mesh group. On the other hand, in the non-mesh group, 1 acute evisceration (2.7%) and 4 incisional hernia of the assistance incision were observed (10.8%). There were no significant differences between groups regarding trocar incisional hernia (6.6 vs. 5.4%). Conclusions: The implantation of a reinforcement prophylactic mesh in overweight or obese patients undergoing laparoscopic colorectal surgery is safe and seems to reduce the short-term rate of incisional hernia. Fixation with cyanoacrylate is a rapid method that facilitates the procedure without additional complications (AU)

The aplication of cyanoacrilate surgical glue on skin suture in rats

Abstract Purpose: To compare the use of a new cyanoacrylate-based surgical glue and suture with sepa-rate points in skin wounds closure. Methods: Thirty-six rats were subjected to a 4cm dorsal longitudinal incision. Twelve were sub-jected to simple suture with polyamide 6-0, 12 rats underwent wall synthesis using Dermabond(r) and 12 was performed cutaneous synthesis with N-2-Butyl-Cyanoacrylate. Twelve of each group was euthanized on the seventh postoperative day, their blood was taken to biochemical tests and a layer of skin and subcutaneous tissue surrounding the surgical scar was randomly divided in two segments, to the submission of tension tests and to histological study. Results: There were no significant difference between groups (p>0.05). In the soft dermis there was more type I collagen production in group I (p<0.05), group II and III was similar re-sults (p>0.05). In the compact dermis, all 3 groups showed similar results (p>0.05). The biomechanical study was similarity between the glue groups (p>0.05) but the group III proved to be different from the others having a higher resistance (p>0.05) . Conclusion: This glue does not cause any inflammation or kidney and hepatic toxicity. Polyamide sutures are more resistant and the glue should be used alone only in less tension are-as.

Abrupt occlusion of right gastroepiploic artery as an angiographic evidence of gastrointestinal hemorrhage

Angiography plays an important role in both diagnosis and treatment of gastrointestinal (GI) bleeding; however, the sensitivity is low for diagnosis. We report a case of a 38-year-old woman who presented with recurrent upper GI bleeding following central pancreatectomy. Multiple selective arteriograms failed to reveal any active bleeding or other common signs of bleeding. There was an abrupt occlusion of the right gastroepiploic artery initially interpreted to be a surgical ligation. Upon direct superselective injection near the occlusion, an area of frank contrast extravasation was demonstrated immediately beyond the occlusion. The underlying vessel was embolized with n-butyl cyanoacrylate without recurrent bleeding up to 3-month follow-up (AU)
