RESUMO

BACKGROUND: Tissue adhesives are a feasible option to fix a hernia repair mesh, avoiding tissue trauma of suture fixation. Classically, they are applied in the form of a drop, although novel applications such as spray are emerging. This study compares the use of a new experimental cyanoacrylate (n-butyl) in the form of a spray or drops. MATERIALS AND METHODS: Three study groups of New Zealand White rabbits were established (n = 6 each) according to the method used to fix a 5 × 3 cm polypropylene mesh in a partial abdominal wall defect model: control group (polypropylene stitches), adhesive drops group, and adhesive spray group. Morphological, immunohistochemical, and biomechanical strength studies were performed at 14 d postimplant. Collagen 1/3 gene ratio was determined by quantitative reverse transcription polymerase chain reaction. RESULTS: In the drops group, the adhesive obstructed the mesh pores and prevented tissue infiltration at the points of application. When the adhesive was applied as a spray, although more numerous, adhesive deposits were smaller and allowed for better host tissue infiltration into the mesh. The inflammatory response was similar in the adhesive groups and more intense than in the control group. Collagen 1/3 mRNA ratio was significantly higher in the spray than the control group. The mechanical resistance of the meshes was similar in all three groups. CONCLUSIONS: The application of the cyanoacrylate adhesive in the form of spray to fix polypropylene meshes in an animal model had a similar inflammatory response compared with droplet application. Neither application impacted the mechanical strength of the repaired area. An increased in collagen 1/3 ratio was found with cyanoacrylate spray compared with suture, and future studies should focus on this pathway.

RESUMO

OBJECTIVES: Cyanoacrylate glue is injected for incompetent great saphenous vein (GSV) treatment 5 cm distal to the saphenofemoral junction (SFJ). Although a few reports have investigated the postprocedural remnant stump length, none have focused on the factors affecting glue extension length and the consequent remnant stump length. METHODS: Seventy-nine patients undergoing cyanoacrylate closure using the VenaSeal system at our clinic between August 2018 and November 2018 were investigated. The GSV diameter was measured just before treatment in the supine position 3 cm distal to the SFJ. Cyanoacrylate glue was injected 5 cm distal to the SFJ. RESULTS: The mean glue extension length was 1.13 ± 1.12 cm. The GSV diameter and glue extension length exhibited a significant inversely proportional relationship (P < .001). More specifically, patients with a GSV diameter ≥0.7 cm had a longer remnant stump length than those with a smaller GSV diameter (P < .001). CONCLUSIONS: An increased GSV diameter is likely associated with a decreased glue extension length and, consequently, a longer remnant stump.

RESUMO

BACKGROUND: Gastric fistulas, bleeding, and strictures are commonly reported after laparoscopic sleeve gastrectomy (LSG), that increase morbidity and hospital stay and may put the patient's life at risk. We report our prospective evaluation of application of synthetic sealant, a modified cyanoacrylate (Glubran®2), on suture rime, associated with omentopexy, to identify results on LSG-related complications. METHODS: Patients were enrolled for LSG by two Bariatric Centers, with high-level activity volume. Intraoperative recorded parameters were: operative time, estimated intraoperative bleeding, conversion rate. We prospectively evaluated the presence of early complications after LSG during the follow up period. Overall complications were analyzed. Perioperative data and weight loss were also evaluated. A control group was identified for the study. RESULTS: Group A (treated with omentopexy with Glubran®2) included 96 cases. Control group included 90 consecutive patients. There were no differences among group in terms of age, sex and Body Mass Index (BMI). No patient was lost to follow-up for both groups. Overall complication rate was significantly reduced in Group A. Mean operative time and estimated bleeding did not differ from control group. We observed three postoperative leaks in Group B, while no case in Group A (not statistical significancy). We did not observe any mortality, neither reoperation. Weight loss of the cohort was similar among groups. In our series, no leaks occurred applying omentopexy with Glubran®2. CONCLUSION: Our experience of omentopexy with a modified cyanoacrylate sealant may lead to a standardized and reproducible approach that can be safeguard for long LSG-suture rime. TRIAL REGISTRATION: Retrospective registration on clinicaltrials.gov PRS, with TRN NCT03833232 (14/02/2019).

RESUMO

AIMS: The aim of this study was to explore risk factors for complications associated with dural tear (DT), including the types of DT, and the intra- and postoperative management of DT. PATIENTS AND METHODS: Between 2012 and 2017, 12 171 patients with degenerative lumbar diseases underwent primary lumbar spine surgery. We investigated five categories of potential predictors: patient factors (sex, age, body mass index, and primary disease), surgical factors (surgical procedures, operative time, and estimated blood loss), types of DT (inaccessible for suturing/clipping and the presence of cauda equina/nerve root herniation), repair techniques (suturing, clipping, fibrin glue, polyethylene glycol (PEG) hydrogel, and polyglycolic acid sheet), and postoperative management (drainage duration). Postoperative complications were evaluated in terms of dural leak, prolonged bed rest, headache, nausea/vomiting, delayed wound healing, postoperative neurological deficit, surgical site infection (SSI), and reoperation for DT. We performed multivariable regression analyses to evaluate the predictors of postoperative complications associated with DT. RESULTS: In total, 429/12 171 patients (3.5%) had a DT. Multivariable analysis revealed that PEG hydrogel significantly reduced the incidence of dural leak and prolonged bed rest, and that patients treated with sealants (fibrin glue and PEG hydrogel) significantly less frequently suffered from headache. A longer drainage duration significantly increased the incidence of headache, nausea/vomiting, and delayed wound healing. Headache and nausea/vomiting were significantly more prevalent in younger female patients. Postoperative neurological deficit and reoperation for DT significantly depended on the presence of cauda equina/nerve root herniation. A longer operative time was the sole independent risk factor for SSI and was also a risk factor for dural leak, prolonged bed rest, and nausea/vomiting. CONCLUSION: Sealants, particularly PEG hydrogel, may be useful in reducing symptoms related to cerebrospinal fluid leakage, whereas prolonged drainage may be unnecessary. Younger female patients should be carefully treated when DT occurs. Cite this article: Bone Joint J 2019;101-B:1115-1121.

RESUMO

Introduction: The most recent guidelines vary in their approach to the management of variceal bleeding especially with the use of endoscopic sclerotherapy (ES) and endoscopic tissue adhesive (ETA). This review highlights their clinical use for variceal bleeding from different guidelines perspectives. Areas covered: A comprehensive literature review of three major guidelines including the American Association for the Study of Liver Diseases (AASLD) 2017, United Kingdom (UK) guidelines 2015 and Baveno VI Consensus workshop guidelines in 2015 on the use of ES and ETA in variceal bleeding. Expert opinion: While endoscopic band ligation (EBL) completely replaced endoscopic sclerotherapy (ES) for esophageal varices. There is a valuable use of endoscopic sclerotherapy (ES) and endoscopic tissue adhesive (ETA) especially for patients with gastroesophageal varices (GOV2) and isolated gastric varices (IGV2). The current standard of care heading toward portosystemic shunting with Trans-jugular-Intrahepatic Portosystemic Shunt (TIPS) and balloon retrograde transvenous obliteration (BRTO). However, recent advancement in endoscopic ultrasound (EUS) allowing direct injection of sclerosant and tissue adhesive into the varix bringing promising results in achieving hemostasis and lowering the risk of complications. Also, ES and ETA have great clinical value in achieving hemostasis for isolated (ectopic) varices and stomal varices.

RESUMO

PURPOSE: To determine whether the use of fibrin sealant impacted the rate of postoperative wound complications following parotidectomy. METHODS: We retrospectively reviewed 100 consecutive parotidectomies with and without fibrin sealant. Primary outcomes were development of seroma, sialocele, abscess, or hematoma within the first 30 days as well as length of hospital stay for drain output if one was placed. Secondary outcomes analyzed wound complications based on several patient and surgical factors. RESULTS: In our cohort, there were 82 superficial parotidectomies (82%), and the most common pathology was pleomorphic adenoma (39%) followed by Warthin's tumor (27%). Fibrin sealant was used in 46 patients (46%). Postoperative wound complications occurred in 20 patients, and were not statistically different with or without fibrin sealant placement (23.9% vs. 16.7%, p = 0.454). Fibrin sealant did not significantly reduce wound complications regardless of tissue volume removed, use of acellular dermis, history of smoking, diagnosis of diabetes, or active anticoagulant/antiplatelet use. Only four patients without fibrin sealant (7.4%) required hospitalization beyond 24 h for high drain output. CONCLUSIONS: In our retrospective cohort, the development of postoperative wound complications following parotidectomy did not appear to be significantly impacted by the use of a fibrin sealant.

RESUMO

Aims: To evaluate the safety and effectiveness of percutaneous transhepatic antegrade embolization (PTAE) with 2-octyl cyanoacrylate assisted with balloon occlusion of the left renal vein or gastrorenal shunts (GRSs) for the treatment of isolated gastric varices (IGVs) with large GRSs. Methods: Thirty patients with IGVs associated with large GRSs who had underwent PTAE assisted with a balloon to block the opening of the GRS in the left renal vein were retrospectively evaluated and followed up. Clinical and laboratory data were collected to evaluate the technical success of the procedure, complications, changes in the liver function using Child-Pugh scores, worsening of the esophageal varices, the rebleeding rate, and survival. Laboratory data obtained before and after PTAE were compared (paired-sample t-test). Results: PTAE was technically successful in all 30 patients. No serious complications were observed except for one nonsymptomatic pulmonary embolism. During a mean follow-up of 30 months, rebleeding was observed in 4/30 (13.3%) patients, worsening of esophageal varices was observed in 4/30 (13.3%) patients, and newly developed or aggravated ascites were observed on CT in 3/30 (10%) patients. Significant improvement was observed in Child-Pugh scores (p=0.009) and the international normalized ratio (INR) (p=0.004) at 3 months after PTAE. The cumulative survival rates at 1, 2, 3, and 5 years were 96.3%, 96.3%, 79.9%, and 79.9%, respectively. Conclusion: Balloon-assisted PTAE with 2-octyl cyanoacrylate is technically feasible, safe, and effective for the treatment of IGV associated with a large GRS.

RESUMO

BACKGROUND: Synthetic vascular material use, particularly polytetrafluoroethylene- (PTFE) -based, can be associated with bleeding, which may increase operative time and blood loss. None of the commercially available sealants designed to ensure hemostasis combine bioresorption, high viscosity, hydrophobicity, and compliance with the underlying tissue and on-demand activation. METHODS: A study was designed to assess the biocompatibility and in-vivo performance and bioresorption of a new synthetic on-demand light-activated poly(glycerol-sebacate) acrylate- (PGSA) -based SETALIUM™ Vascular Sealant (TISSIUM, Paris, France) in three large animal studies of open vascular carotid and aortic surgery. The pre-clinical results were then translated into a clinical setting in a prospective, single-arm multicenter study in patients requiring carotid endarterectomy using an ePTFE patch. RESULTS: The biocompatibility testing showed that the PGSA-based SETALIUM™ Vascular Sealant did not induce any significant toxic reaction at a standard clinical dose nor at doses up to 40 times the equivalent intended clinical dose. The PGSA-based sealant was shown to be non-pyrogenic, non-sensitizing, non-irritant, non-clastogenic, and non-mutagenic. The animal studies showed excellent performance and safety results, with clinically significant hemostasis achieved in 100% of the animals in both carotid and aorta studies and excellent local tolerance. Histopathology and morphometric analyses showed surface-based gradual and sustained bioresorption of the PGSA-based sealant up to 86% at 12 months. In the clinical study, the application of the PGSA-based sealant resulted in good performance and safety, with immediate hemostasis achieved in 84% of the cases and no adverse event related to the sealant reported through the one-year follow-up. CONCLUSIONS: The new synthetic on-demand light activated PGSA-based SETALIUM™ Vascular Sealant investigated in our studies demonstrated good biocompatibility, sustained and gradual surface based bioresorption, and acceptable safety profile in animal studies. In addition, the first in-human use showed that the sealant is a safe and effective alternative to achieve fast and controlled hemostasis in vascular carotid reconstructions. A larger randomized controlled study will allow further validation of these encouraging preliminary results.

RESUMO

AIM: To investigate comparative efficacy of a novel absorbable adhesive membrane (TissuePatchDuralTM "TPD") and a fibrin glue (Tisseel "T") in reducing cerebrospinal fluid (CSF) leaks after posterior fossa and spinal procedures, and also to identify potential risk factors for CSF leakage. MATERIAL AND METHODS: This is a single-center, retrospective cohort study of 123 consecutive posterior fossa (n=77) and spinal (n=46) surgeries. Patients were grouped based on dural sealants used 2-group comparison: TPD (n=56) vs. no-TPD (n=67) and 3-group comparison: T only (n=43), TPD only (n=32) vs TPD+T (n=35). RESULTS: Mean age was 38.9 ± 22.2 years (62 males, 61 females). Baseline characteristics were similar between groups. Neither 2-group (TPD: 10.4% vs no-TPD: 8.9%; p=0.778) nor 3-group (T: 9.3% vs TPD: 6.3% vs TPD+T: 14.3%; p=0.539) comparisons revealed a significant difference in postoperative CSF leakage rates. Multivariate analysis showed that diagnosis (non-tumoral vs. tumor) (OR: 5.487; 95% CI: 1.118-26.937; p=0.036); previous surgery (OR: 9.268; 95% CI: 1.911-44.958; p=0.006), postoperative hydrocephalus (OR: 5.456; 95% CI: 1.250-23.821; p=0.024) were independent predictors of postoperative CSF leakage. CONCLUSION: TissuePatchDural < sup > TM < /sup > is a novel dural sealant patch which can be safely used to reinforce dural closure in posterior fossa and spinal surgeries, and its efficacy is comparable to widely used fibrin glue (Tisseel). Non-tumoral pathologies, previous surgery, and postoperative hydrocephalus appear to be independent risk factors for postoperative CSF leakage.

RESUMO

A 65-year-old patient presenting with left labial and perirectal pain was diagnosed with bilateral Tarlov cysts. Upon treatment of the left Tarlov cyst (the right was asymptomatic) using image-guided aspiration and subsequent injection of the cyst with fibrin sealant, the cyst reduced in size. To our knowledge, there are currently no other documented cases in which the Tarlov cyst reduced in size following this procedure. This case would seem to suggest that clinicians are poorly informed with regard to Tarlov cysts. These cysts are more common in Caucasian women, many of whom are told their cysts are not responsible for their pain or that they are not treatable. However, there is clear evidence that some Tarlov cysts are symptomatic and minimally invasive procedures have been developed to treat them. As they primarily occur in women, it is possible gender bias may also play a role in the delayed diagnosis of the patient's pain.

RESUMO

Objective: To differentiate the inflow and outflow channels of gastric varices in cirrhotic portal hypertension patients using multi-slice spiral CT (MSCT), and to assess the relationship between calculable CT volume of gastric varices and the amount of tissue adhesive. Methods: 97 cases with cirrhotic gastric varices who were admitted from November 2013 to August 2017 were selected. The type and shape of gastric varices were observed before tissue glue injection treatment by MSCT. The correlation between CT volume of gastric varices and the amount of tissue adhesive was evaluated by Spearman rank correlation coefficient and Univariate linear regression analysis. Results: MSCT showed that Le, g type had the highest proportion (54.6%), followed by Le, g, Lg (20.6%). Le, Lg and Lgf type accounted for 17.5%, and 5.2%, respectively, while Lgf+b accounted for 2.1%. On MSCT, varices of the gastric fundus were in the direction from bottom to top, and 75% of the fundus had a large curved side varices combined with gastric and renal shunt. Under the gastroscopy, varices in the small curved side of the gastric fundus from near to far were formless. In addition, varices in the large curved side of the gastric fundus when observed from different angles to the direction of blood flow (reverse gastroscope) were 72.7% (near and far) or 20.5 % (far and near). There was a positive correlation between CT volume (R = 0.97, P < 0.001) and the amount of tissue adhesive (Y(1) = 0.35 + 0.65X1, Univariate linear regression equation; ρ = 0.89, P < 0.001, Spearman correlation analysis). Conclusion: MSCT can recognize the vascular shape and inflow and outflow channels of gastric varices. A positive correlation between CT volume and the amount of tissue adhesive, suggested that the CT volume measurement before treatment could be used as one of the method to predict the amount of tissue adhesive.

RESUMO

OBJECTIVES: To study the therapeutic effect of early local drug therapy on pancreatic contusion and laceration. METHODS: Twenty pigs were divided into 4 groups: model(PL), 1 ml of saline; medical protein glue (EC), 1 ml of medical protein glue; ulinastatin (UL), 50000U of ulinastatin; combined treatment (UE), 1 ml of medical protein glue and 50000U of ulinastatin. 30 min after model establishment, different groups received different local drug treatments. The pancreatic function, peritoneal effusion and pancreatic pathology were observed. RESULTS: The UE group got the best therapeutic effect. The changes of pancreatic function and the peritoneal effusion were compared with PL group as follows. 0-6h: amylase (p < 0.01), lipase (p > 0.05), effusion (p < 0.01); 6-12h: amylase (p > 0.05), lipase (p < 0.01), effusion (p < 0.01); 12-24h: amylase (p < 0.01), lipase (p < 0.01), effusion (p < 0.01). CONCLUSIONS: Early local drug therapy in pancreatic contusion and laceration could effectively control the development of the disease and improve the prognosis.

RESUMO

BACKGROUND: Esophageal cancer is surgically treated by means of an esophagectomy. However, esophagectomies are associated with high morbidity rates with dehiscence of the anastomosis occurring in 19% of these procedures in the Netherlands. Application of a fibrin sealant may improve mechanical strength of the anastomosis. The aim of this study was to determine the technical feasibility of the application of an autologous fibrin sealant by aerosolized spraying on esophageal anastomoses. METHODS: This study was designed as a single-center feasibility study. Patients undergoing elective minimal invasive esophageal surgery with the creation of a thoracic or a cervical anastomosis were eligible. Fibrin sealant (Vivostat) was applied to the anastomosis intraoperatively. Feasibility was measured using a nine-item checklist, designed for intraoperative application. RESULTS: In total, fifteen patients, between the ages of 43-79 y, were included in this study. One procedure scored eight out of nine points on the feasibility checklist, so application was considered as unsuccessful. The other fourteen procedures obtained a 100% score and were documented as successful procedures. Together, this led to a success rate of 93%. Grade III anastomotic leakage occurred in one of the fifteen patients (6.7%). CONCLUSIONS: This study showed that application of fibrin sealant on esophageal anastomoses is technically feasible and safe. Future studies may investigate the possible protective effects of fibrin sealant application on the development of anastomotic leakage. NCT03251040.

RESUMO

A 74-year-old female, who was diagnosed with superficial esophageal cancer, underwent endoscopic submucosal dissection (ESD) at another hospital, but a perforation occurred during the procedure. The perforation was closed with endoscopic clips, and the ESD was halted. The patient was referred to our hospital, and ESD was retried. There was severe fibrosis around the lesion, and injections into the submucosal layer were difficult. In addition, it was not possible to identify the submucosal layer, and making an oral-side incision caused a large perforation along the incision line. As continuing the submucosal dissection with an endoknife was considered difficult, the lesion was finally resected with hybrid ESD using a snare. The perforation was closed using polyglycolic acid (PGA) sheets and fibrin glue. Endoscopy performed 6 days later showed that the defect had been closed, and no contrast leakage was detected. Follow-up endoscopy conducted 3 months after the ESD showed ulcer healing at the dissection site and scar formation, but no residual tumor or esophageal stricture was noted. Our experience suggests that the use of PGA sheets with fibrin glue is a feasible, safe, and effective way of treating large esophageal perforations during ESD.

RESUMO

PURPOSE:: The use of cyanoacrylate for intravenous catheter securement is of interest to clinicians and patients, because of the superior adhesive strength and hemostatic effect of cyanoacrylate compared to current securement devices. The purpose of this study is to use novel in vitro and in vivo testing methods to analyze the hemostatic effect of a catheter securement cyanoacrylate (cyanoacrylate). METHODS:: An unprecedented in vitro method was performed to determine the effects of a cyanoacrylate on a customized modified activated clotting time assay and blood flow inhibition assay by exposing blood or plasma to either one or three drops of cyanoacrylate. For the in vivo testing, full-thickness incisions were made on swine, and the bleeding was scored prior to treatment and at 3, 6, 9, and 12 min after treatment. RESULTS:: The cyanoacrylate rapidly achieved hemostasis in the presence of anticoagulated whole blood, platelet-poor plasma, and non-anticoagulated whole blood, in vitro. The cyanoacrylate achieved hemostasis 12-fold faster than thromboplastin in the modified activated clotting time assay. The cyanoacrylate does not alter normal blood clotting, as measured by prothrombin time. In vivo, the bleeding score of cyanoacrylate prior to treatment and at 3, 6, 9, and 12 min after treatment were 2.3 ± 1.0, 0.3 ± 0.5, 0.2 ± 0.5, 0.2 ± 0.4, and 0.2 ± 0.4, respectively. CONCLUSION:: This study indicates that cyanoacrylate demonstrates a potent mechanical hemostatic effect and cyanoacrylate in the presence of anticoagulated whole blood has an activated clotting time that is 12 times quicker than thromboplastin. The cyanoacrylate was found to be significantly equivalent to two known hemostatic agents, in vivo.

RESUMO

OBJECTIVE: To report the results of endoscopic ultrasound-guided injection of coils with cyanoacrylate (CYA) using a less-expensive coil with an emphasis on the roles of Doppler and endosonographic varicealography (EV) in identifying the feeder vessel in gastric varix treatment. METHODS: An observational, descriptive study with prospectively collected data. Patients with gastric varices (GV) were included and were treated by endoscopic ultrasound-guided injection of CYA and a less-expensive coil. Technical success, complete and immediate variceal obliteration, rebleeding, complication and survival rates were evaluated. RESULTS: Thirty patients with GV with a mean age of 62 years (range: 44-76 years) were treated. Median number of coils used was 2 (range: 1-3), and median volume of CYA was 1.8 mL (1.2-2.4 mL). Technical success rate was 100%. EV technical success was observed in 26/30 patients. Complete variceal obliteration was observed in 96.6% of patients, and immediate disappearance of the varix was observed in 24 (80%) patients. The complication rate was 6.7%. CONCLUSIONS: Endoscopic-ultrasound guidance for gastric varix treatment with the addition of EV and the use of a less-expensive coil is a safe and effective technique that results in the immediate disappearance of GV after targeting the feeding vessel.

RESUMO

Sutureless nerve repair has been regarded as a promising technique for nerve repair as the suture materials often results in neuroma formation and scar tissue that impede nerve regeneration. The aim of this study was to analyze the mechanical stability and morphological outcome of sutureless repair using fibrin glue conduit and an alternative approach of modified suture placement. Using rat sciatic nerve, we tested the following experimental conditions: conventional suture repair; single suture combined with fibrin glue repair, and fibrin conduit reinforced with modified suture or fibrin glue. Nerve detachment anatomical measures such as axon density, myelin, and fiber caliber were analyzed for evaluation of nerve regeneration. Muscle atrophy were evaluated by muscle wet weight and H&E staining. All animals in sutureless repair group exhibited complete detachment or elongation by two or four weeks after repair. No detachment was found in any other groups. Animals treated with fibrin conduit reinforced with modified suture showed better axonal regeneration with good alignment. There were no significant differences in axon caliber among the groups. Muscle atrophy was found in all groups and there was no significant difference in muscle wet-weight among the groups. In summary, sutureless nerve repair with fibrin glue was mechanically unstable for resistance of mechanical stretches, fibrin glue conduit with modified suture placement is mechanically stable and resulted in better morphological outcome.
