Comparison conventional endoscopic myringoplasty with fibrin glue supplemented endoscopic myringoplasty

Introduction: The fibrin tissue glues have been used in many surgeries to reinforce surgical sutures and tissue adhesion. Myringoplasty is the commonly done ear surgery for the perforations of the tympanic membrane, where no suturing is done between remnant membrane and graft. Aim: The aim of the study is to compare the results and effectiveness of this biological fibrin tissue glue in myringoplasty surgeries as a supplementary procedure to conventional endoscopic myringoplasty (CEM) surgeries. Materials and Methods: Seventy patients with chronic suppurative otitis media with tympanic membrane perforation without ossicular and mastoid involvement have been chosen. One group of 35 patients underwent CEM surgeries. In another group of 35 patients, biological fibrin tissue glue, TISSEEL, has been used as supplementary to the CEM surgeries, and the graft uptake rate and hearing improvement were evaluated and compared postoperatively. Results: The graft success rate at 3 months postoperatively was 91.42% in both the groups, that is, 32/35, and these values were not statistically significantly different (P = 1.00). There was a highly statistically significant hearing outcome before and after the surgery in both the CEM and the fibrin tissue glue supplemented endoscopic myringoplasty groups. However, there was no statistically significant change in hearing outcomes between the two groups. Conclusion: In our study, we have got more or less similar results compared with the results of the studies on routine CEM cases. But the high-cost nature of the commercially available fibrin tissue glue makes it difficult to recommend for use in all routine endoscopy myringoplasty cases

Experimental Evaluation of Chitosan Membrane and Collagen Sponge (TachoSil®) as Sealants in Cardiovascular Surgery

ABSTRACT Introduction: The objectives of this study are to experimentally evaluate the haemostatic effects of two organic substances, a membrane of chitosan and a collagen sponge coated with thrombin and human fibrinogen (TachoSil®), in sealing 7-0 needle stitches holes on the femoral arteries of rats as well as to evaluate local histological reactions. Methods: Twenty-four rats were included, and four holes were made in each common femoral artery. In the control group, haemostasis was achieved only by compression with gauze sponge; and in the two other groups, haemostasis was achieved with application of one of these two substances. Results: Membrane of chitosan and TachoSil® showed a power to reduce the time to achieve haemostasis compared with the control group (P=0.001), and the haemostatic effects of these two substances were comparable. There was lower blood loss in the groups where these two substances were used when compared with the control group, but no difference was found comparing the two substances. Conclusion: The use of these sealants did not promote more adhesion or local histological reactions when compared to the control group. Since chitosan is easy to find in nature, has a positive effect to promote haemostasis, and did not bring considerable local reactions, it might be used as a sealant in cardiovascular surgery.

Effect of application of fibrin glue on vocal fold healing after surgical manipulation in rabbits / Efeito da aplicação de cola de fibrina na cicatrização de pregas vocais após manipulação cirúrgica em coelhos

Abstract Introduction A challenge in phonosurgery is achieving good vocal quality with minimal vocal fold fibrosis. Fibrin glue can be applied to minimize fibrosis; however, its use in the larynx is based primarily on clinical experience, particularly in extensive lesions. Objective The objective of this study was to evaluate the effect of application of fibrin glue on collagen concentration at the late phase of the healing process after detaching a pedicled flap of the vocal fold cover in rabbits. Methods In this prospective animal study, twelve adult male rabbits underwent laryngeal microsurgery, in which an incision was made along the entire length of both vocal folds, followed by extensive mucosal detachment and section of the incision ends. Fibrin glue was applied in the left vocal fold, and the mucosa was repositioned. In the right vocal fold, the mucosa was repositioned without treatment with fibrin glue. After 3-months, the rabbits were euthanized. Histological analyses were performed, and the data collected were subjected to statistical analysis. Results Vocal folds treated with fibrin glue presented higher collagen concentration in Masson trichrome staining and significantly higher (p< 0.05) collagen concentration in picrosirius red staining compared to control vocal folds. Conclusion Treatment with fibrin glue led to greater vocal fold fibrogenesis in the present study. Nonetheless, further studies are necessary to determine the prophylactic effect of sealants in laryngeal surgeries that require extensive detachment of the vocal fold cover.

Resumo Introdução Um desafio na fonocirurgia é conseguir uma boa qualidade vocal com o mínimo de fibrose das pregas vocais. A cola de fibrina pode ser aplicada para minimizar a fibrose; porém, seu uso na laringe é baseado principalmente na experiência clínica, particularmente em lesões extensas. Objetivo Avaliar o efeito da aplicação da cola de fibrina na concentração de colágeno na fase tardia do processo de cicatrização, após o descolamento do retalho pediculado da cobertura da prega vocal em coelhos. Método Neste estudo prospectivo com animais, 12 coelhos adultos machos foram submetidos à microcirurgia de laringe, na qual uma incisão foi feita em toda a extensão de ambas as pregas vocais, seguida de extenso descolamento da mucosa e secção das extremidades da incisão. A cola de fibrina foi aplicada na prega vocal esquerda e a mucosa foi reposicionada. Na prega vocal direita, a mucosa foi reposicionada sem tratamento com cola de fibrina. Após três meses, os coelhos foram sacrificados. Análises histológicas foram feitas e os dados coletados foram submetidos à análise estatística. Resultados As pregas vocais tratadas com cola de fibrina apresentaram maior concentração de colágeno na coloração tricrômica de Masson e concentração significativamente maior de colágeno (p < 0,05) na coloração com picrosirius red comparadas às pregas vocais controle. Conclusão O tratamento com cola de fibrina resultou em maior fibrogênese das pregas vocais no presente estudo. Contudo, novos estudos são necessários para determinar o efeito profilático dos selantes em cirurgias de laringe que requerem extenso descolamento da cobertura das pregas vocais.

Comparative analysis of endoscopic ligation and tissue adhesive injection for tortuous gastric varices / 中华消化内镜杂志

Objective:To evaluate the risks and benefits of endoscopic ligation and tissue adhesive injection for tortuous gastric varices.Methods:A total of 193 patients with esophagogastric varices, who underwent endoscopic variceal ligation or endoscopic tissue adhesive injection in Department of Gastroenterology of the First Affiliated Hospital of Anhui Medical University from June 2015 to June 2020, were included in the retrospective analysis. These cases were connected vessels (type Le and gf based on LDRf standard) of tortuous gastric varices (F1 in Hashizume standard). According to the treatment, the patients were divided into three groups: gastric fundus and esophageal ligation group (endoscopic ligation of gastric fundus and esophageal varices, 32 cases), tissue adhesive group (endoscopic tissue adhesive injection of gastric varices, endoscopic ligation of esophageal varices, 71 cases) and esophageal ligation group (endoscopic ligation of esophageal varices, 90 cases). The re-bleeding rate, the effectiveness rate, the significant effectiveness rate and complications of the three groups were compared.Results:The rates of re-bleeding in gastric fundus and esophageal ligation group, tissue adhesive group and esophageal ligation group were 18.75% (6/32), 12.68% (9/71) and 3.33% (3/90), respectively.There was significant difference only between gastric fundus and esophageal ligation group and esophageal ligation group ( χ2=6.110, P<0.016). The effectiveness rates of the three groups were all 100.00%. The significant effectiveness rates in gastric fundus and esophageal ligation group, tissue adhesive group and esophageal ligation group were 37.50% (12/32), 25.35% (18/71) and 14.44% (13/90), respectively. There was significant difference only between gastric fundus and esophageal ligation group and esophageal ligation group ( χ2=7.702, P<0.016). No pulmonary infection, hepatic encephalopathy, spontaneous bacterial peritonitis or perforation occurred in the three groups.The incidences of chest pain or abdominal pain in gastric fundus and esophageal ligation group, tissue adhesive group and esophageal ligation group were 18.75% (6/32), 11.27% (8/71) and 2.22% (2/90), respectively.There was significant difference only between gastric fundus and esophageal ligation group and esophageal ligation group ( χ2=10.524, P<0.016). There was no significant difference in the incidence of fever, nausea or vomiting among the three groups ( P>0.05). Conclusion:Simultaneous endoscopic ligation of gastric fundus and esophageal varices, and endoscopic tissue adhesive injection of gastric varices combined with endoscopic ligation of esophageal varices is of no benefit for patients with tortuous gastric varices, but endoscopic ligation of esophageal varices alone may yield more benefit.

Amniotic membrane graft after excision of widespread conjunctival concretions / Enxerto de membrana amniótica após remoção de concreções conjuntivais

ABSTRACT Conjunctival concretions are single or clustered lesions frequently found on the palpebral conjunctiva. They are commonly present in older individuals, despite being rarely symptomatic. This case report describes an 83-year-old man with multiple conjunctival concretions, which were surgically treated. The patient was symptomatic on presentation and did not respond to conservative treatment. For this reason, a surgical approach was considered. After wide excision of the conjunctival lesions, a piece of amniotic membrane was fitted using fibrin glue. During follow-up, a markedly improvement in patient's symptoms was observed, along with nearly complete absence of conjunctival concretions. This is the first case report addressing extensive conjunctival concretions with a surgical approach using amniotic membrane. The authors conceived the technique described after noticing the limited clinical options in the literature. This technique was easily performed and achieved satisfactory results.

RESUMO As concreções conjuntivais representam lesões amareladas, simples ou múltiplas, frequentemente encontradas na conjuntiva palpebral. São mais prevalentes em idades avançadas e raramente sintomáticas. Este relato de caso descreve o quadro clínico de um paciente de 83 anos com múltiplas concreções conjuntivais, cirurgicamente tratadas. Por se tratar de um paciente sintomático com resposta insuficiente ao tratamento conservador, foi considerada a abordagem cirúrgica. Após remoção das lesões, foi aplicado um enxerto de membrana amniótica, adaptado com cola de fibrina. No acompanhamento pós-operatório, verificou-se melhoria significativa dos sintomas, com desaparecimento quase total das concreções conjuntivais. Este é o primeiro caso que descreve uma abordagem cirúrgica com utilização de membrana amniótica na resolução desse tipo de lesões. A técnica, de fácil execução e com resultados muito favoráveis, foi desenvolvida pelos autores após constatarem a escassez de alternativas na literatura.

Chronic venous ulcers: a review on treatment with fibrin sealant and prognostic advances using proteomic strategies

Venous ulcers are the main causes of chronic lower-limb ulcers. The healing difficulties encourage the research and development of new products in order to achieve better therapeutic results. Fibrin sealant is one of these alternatives. Besides being a validated scaffold and drug delivery system, it possesses excellent healing properties. This review covered the last 25 years of the literature and showed that the fibrin sealant is used in various clinical situations to promote the healing of different types of ulcers, especially chronic ones. These are mostly venous in origin and usually does not respond to conventional treatment. Commercially, only the homologous fibrin sealants obtained from human blood are available, which are highly efficient but very expensive. The heterologous fibrin sealant is a non-commercial experimental low-cost product and easily produced due to the abundance of raw material. The phase I/II clinical trial is already completed and showed that the product is safe and promisingly efficacious for the treatment of chronic venous ulcers. In addition, clinical proteomic strategies to assess disease prognosis have been increasingly used. By analyzing liquid samples from the wounds through proteomic strategies, it is possible to predict before treatment which ulcers will evolve favorably and which ones will be difficult to heal. This prognosis is only possible by evaluating the expression of isolated proteins in exudates and analysis using label-free strategies for shotgun. Multicentric clinical trials will be required to evaluate the efficacy of fibrin sealant to treat chronic ulcers, as well as to validate the proteomic strategies to assess prognosis.(AU)

Comparing intra-oral wound healing after alveoloplasty using silk sutures and n-butyl-2-cyanoacrylate

OBJECTIVES: The need for proper wound closure is of paramount importance after any intra-oral surgery. Various wound closure techniques have been described in literature using traditional non-absorbable suture materials. These include like synthetic absorbable sutures, surgical staples and tissue adhesives. Cyanoacrylates are among the most commonly used biocompatible tissue adhesives. To evaluate and compare intraoral wound healing using 3-0 silk sutures and n-butyl-2-cyanoacrylate after alveoloplasty.MATERIALS AND METHODS: A total of 20 patients requiring bilateral alveoloplasty in the same arch (upper or lower) were included in this study. Patients with any pre-existing pathology or systemic disease were excluded. After alveoloplasty was performed, the wound was closed using 3-0 braided silk sutures on one side, and using n-butyl-2-cyanoacrylate bio adhesive on the other side. Patients were evaluated based on the following parameters: time required to achieve wound closure; the incidence of immediate and postoperative hemostasis; the time to the use of the first rescue medication; the side where pain first arises; and the side where wound healing begins first.RESULTS: Compared to 3-0 silk sutures, cyanoacrylate demonstrated better hemostatic properties, reduced operative time, reduced postoperative pain and better wound healing.CONCLUSION: These data suggest that cyanoacrylate glue is an adequate alternative to conventional sutures to close the surgical wound after alveoloplasty, and better than are 3-0 silk sutures.

Comparison of Wound Closure using Octylcyanoacrylate Tissue Adhesive versus Subcuticular Suture in Inguinal Hernia Surgery

In our study, we have compared inguinal hernia skin closure with octylcyanoacrylate tissue adhesive and subcuticular suturewith 4-0 Monocryl. We found that time require for closure is significantly less with using glue. Hospital stay are less in glue groupcompare to subcuticular group but not significant. Incidence of infection is more in subcuticular group. Cosmetic outcome of scaris equally good in glue as compared to sutures. Post op pain is less in glue group. Inguinal hernia is a common surgical problemand the usual treatment is Lichtenstein mesh hernioplasty. Wound closure is usually done by interrupted sutures, subcuticularsutures, or staples. Tissue adhesive octylcyanoacrylate is an alternative method for skin closure, which is a new generation longchain tissue adhesive. In this study, we will be comparing the outcome of tissue adhesive octylcyanoacrylate with subcuticularsuture for closure of inguinal hernia surgery in adults in terms of time efficiency, cosmesis, pain, and wound complications

Comparación del tiempo de cicatrización entre N-butil cianoacrilato y ácido poliglicólico en caninos sometidos a esterilización / Comparison of healing times between N-butyl cyanoacrylate and polyglycolic acid in canines subjected to sterilization

RESUMEN El objetivo de este estudio fue comparar el tiempo de cicatrización entre N-butil cianocrilato (NBC) y ácido poliglicólico (AC) sobre el cierre tisular en caninos sometidos a operaciones de esterilización. Se realizó un estudio observacional, comparativo y descriptivo sobre una población de 80 perros (Canis familiaris) vivos. Los animales se dividieron en cuatro grupos de 20 perros cada uno según sexo y material de sutura, así: primero grupo, hembras que recibieron NBC; segundo grupo, machos y NBC; tercero grupo, hembras y AC como medio de sutura en piel y cuarto grupo, machos y AC. La técnica quirúrgica en hembras fue oforosalpingohisterectomia y en machos orquiectomia. El tiempo de cierre fue estadísticamente (p < 0,05) menor en los grupos de machos y hembras con el adhesivo NBC comparado con los dos grupos tratados con AC. Se concluye que el NBC es un material seguro y eficaz como medio de fijación tisular en ambas técnicas quirúrgicas que disminuye los días de cierre y recuperación.

ABSTRACT The aim of this study was to compare N-butyl cyanoacrylate (NBC) and polyglycolic acid (AC) in tissue closure in canines subjected to sterilization operations. An observational, comparative and descriptive study was conducted in a population of 80 living dogs (Canis familiaris). The animals were divided into 4 groups of 20 dogs each, according to gender and suture material: the first group consisted of females that received NBC; the second group consisted of males that received NBC; the third group consisted of females that received AC as skin suture; and the fourth group was formed by males that received AC. The surgical technique in females was salpingo-oophorectomy, and in males it was orchiectomy. The closure time was statistically (p < 0.05) lower in the male and female groups with the NBC adhesive in comparison to the two groups treated with AC. It was concluded that NBC is a safe and effective material for tissue fixation in both surgical techniques, decreasing times of closure and recovery.

Multiple epidural fibrin glue patches in a patient with spontaneous intracranial hypotension:A case report

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous leakage of cerebrospinal fluid, with postural headache as the primary symptom. Orthostatic headache caused by SIH is often not resolved by conservative management. CASE: We performed 15 epidural blood patch treatments in a 43-year-old female patient; however, they were only transiently effective. To improve the patient's SIH and orthostatic headache, epidural fibrin glue patch treatment was attempted. Fibrin glue is a substance that can act as a bio-friendly adhesive by facilitating the coagulation cascade. In our case, 3 epidural fibrin glue patch treatments were performed and the symptoms completely resolved. CONCLUSIONS: The epidural fibrin glue patch may be beneficial for the treatment of refractory postural headaches caused by SIH.

The effect of fibrin glue in preventing staple-line leak after sleeve gastrectomy. An experimental study in rats

Abstract Purpose To evaluate the effect of fibrin glue on staple-line leak after sleeve gastrectomy. Methods Fourteen adult wistar rats 300 gr were randomized into two groups: Control group (n=7) and study group (n=7). All the rats underwent sleeve gastrectomy using lineer stapler. In the study group, fibrin glue was used to reinforce the staple-line. The rats were sacrificed 7 days after surgery. The stomach was resected, submerged in saline and exposed to excess pressure to obtain a burst pressure value. The gastric staple line was evaluated histopathologically according to the Ehrlich Hunt scale. The results of the two groups were compared. Results The mean Ehrlich-Hunt scores for inflammation, fibroblastic activity and neo-angiogenesis were similar between the groups (p>0.05). Collagen deposition was significantly higher in study group (3.42±0.53) when compared with control group (2.57±0.78) (p=0.035). The mean burst pressure was 137.8±8.5 mmHg for control group and 135.0±8.1 mmHg for study group (p=0.536). Conclusion Reinforcement of the staple-line with fibrin glue has no effect on the burst pressure after sleeve gastrectomy. More studies are needed to evaluate the precautions against leak after sleeve gastrectomy.

Fibrin sealant repair of a double-necked femoral pseudoaneurysm

SUMMARY Pseudoaneurysms are rare, but femoral artery false aneurysms have increased in recent decades. They are related to endovascular procedures performed on patients with increased risk for this complication. Pseudoaneurysms generally present with only one neck. This paper describes a femoral artery pseudoaneurysm with two necks that occurred after an endovascular procedure and was successfully treated by duplex-guided fibrin sealant. Pseudoaneurysms are rare, but femoral artery pseudoaneurysms have increased with a discrepant incidence reported from 0.5% to almost 4%, mainly related to the increase of endovascular procedures in recent decades. The double-necked pseudoaneurysm identification was of utmost importance to guide the clinical decision-making and allowed good outcomes for the patient.

RESUMO Os pseudoaneurismas são raros, mas os aneurismas falsos da artéria femoral aumentaram nas últimas décadas. Eles estão relacionados aos procedimentos endovasculares realizados em pacientes com risco aumentado para esta complicação. Os pseudoaneurismas geralmente apresentam apenas um colo. Este artigo descreve um pseudoaneurisma da artéria femoral com dois colos que ocorreu após um procedimento endovascular e foi tratado com sucesso por selante de fibrina guiado por duplex. Os pseudoaneurismas são raros, mas os pseudoaneurismas da artéria femoral aumentaram com uma incidência discrepante relatada de 0,5% a 4%, principalmente relacionada ao aumento dos procedimentos endovasculares nas últimas décadas. A identificação do pseudoaneurisma de colo duplo foi de extrema importância para orientar a tomada de decisão clínica e permitiu bons resultados para o paciente.

Comparative Study Of Fixation Of Split Skin Graft With Suture Versus Cyanoacrylate Tissue Adhesive

Skin is considered to be the best covering of Human body. Because it interfaces with the environment, it plays an important immunity role in protecting the body against pathogens [1]. Skin performs many important and crucial functions of body, therefore loss of skin results in many complications. Because of which it is imperative to cover skin loss at the earliest. There are many options available to cover skin loss and one of the best and convenient methods is Split skin Grafting (SSG). However, SSG fails, if not fixed. If not fixed, mobilization of graft may occur leading to failed revascularization and then necrosis of graft. Therefore, it is mandatory to fix the split skin graft to donor site for its survival. Many techniques and materials have been used for fixation of split skin graft. Each has its merit and demerit. In this article, we present comparative study of effectiveness of fixation of SSG with sutures versus Cyanoacrylate tissue adhesive

Comparison of injecting tissue glue and lauromacrogol in modiifed sandwich method with synchronization or sequential ligation for esophageal and gastric variceal / 中国内镜杂志

Objecive To evaluate and compare the efficacy of injecting tissue glue and lauromacrogol in modified sandwich method combined with synchronous ligation for patients with esophageal and gastric variceal.Methods 42 cases of patients with esophageal and gastric variceal were randomly divided into synchronous treatment group (22 cases) and sequential treatment group (20 cases). Both group received modiifed sandwich method for gastric varices (lauromacrogol-tissue adhesive-lauromacrogol). Synchronous treatment group meanwhile received synchronization ligation for esophageal varices, but sequential treatment group received sequential ligation after one week. The hemostasis rate, effective rate of varices, rebleeding and complications rate were analyzed.Results There were no signiifcant difference in hemostasis rate, effective rate and rebleeding rate between two groups. The incidence of complications, such as chest and abdominal pain, fever, transient bacteremia were equal between these two groups. No patients had ectopic embolism. The number of ligation device in synchronous treatment group was more than sequential treatment group (8.19 ± 2.01 vs 7.81 ± 1.78,P > 0.05), and the rate of esophageal varices disappearance was inferior to sequential treatment group (59.09% vs 70.00%), however, there were no statistical difference (P > 0.05).Conclusion Endoscopic injection of tissue glue and lauromacrogol synchronization ligation is safe and effective for esophageal and gastric variceal with low complication rates. This method could reduce gastroscopy times and medical expenses, and is worthy of further investigating.
