RESUMEN

INTRODUCTION: Our objective was to perform a feasibility study using real-world data from a learning health system (LHS) to describe current practice patterns of wound closure and explore differences in outcomes associated with the use of tissue adhesives and other methods of wound closure in the pediatric surgical population to inform a potentially large study. METHODS: A multi-institutional cross-sectional study was performed of a random sample of patients <18 y-old who underwent laparoscopic appendectomy, open or laparoscopic inguinal hernia repair, umbilical hernia repair, or repair of traumatic laceration from January 1, 2019, to December 31, 2019. Sociodemographic and operative characteristics were obtained from 6 PEDSnet (a national pediatric LHS) children's hospitals and OneFlorida Clinical Research Consortium (a PCORnet collaboration across 14 academic health systems). Additional clinical data elements were collected via chart review. RESULTS: Of the 692 patients included, 182 (26.3%) had appendectomies, 155 (22.4%) inguinal hernia repairs, 163 (23.6%) umbilical hernia repairs, and 192 (27.8%) traumatic lacerations. Of the 500 surgical incisions, sutures with tissue adhesives were the most frequently used (n = 211, 42.2%), followed by sutures with adhesive strips (n = 176, 35.2%), and sutures only (n = 72, 14.4%). Most traumatic lacerations were repaired with sutures only (n = 127, 64.5%). The overall wound-related complication rate was 3.0% and resumption of normal activities was recommended at a median of 14 d (interquartile ranges 14-14). CONCLUSIONS: The LHS represents an efficient tool to identify cohorts of pediatric surgical patients to perform comparative effectiveness research using real-world data to support medical and surgical products/devices in children.

RESUMEN

Hydrogels that are mechanically tough and capable of strong underwater adhesion can lead to a paradigm shift in the design of adhesives for a variety of biomedical applications. We hereby innovatively develop a facile but efficient strategy to prepare hydrogel adhesives with strong and instant underwater adhesion, on-demand detachment, high toughness, notch-insensitivity, self-healability, low swelling index, and tailorable surface topography. Specifically, a polymerization lyophilization conjugation fabrication method was proposed to introduce tannic acid (TA) into the covalent network consisting of polyethylene glycol diacrylate (PEGDA) of substantially high molecular weight. The presence of TA facilitated wet adhesion to various substrates by forming collectively strong noncovalent bonds and offering hydrophobicity to allow water repellence and also provided a reversible cross-link within the binary network to improve the mechanical performance of the gels. The long-chain PEGDA enhanced the efficacy and stability of TA conjugation and contributed to gel mechanics and adhesion by allowing chain diffusion and entanglement formation. Moreover, PEGDA/TA hydrogels were demonstrated to be biocompatible and capable of accelerating wound healing in a skin wound animal model as compared to commercial tissue adhesives and can be applied for the treatment of both epidermal and intracorporeal wounds. Our study provides new, critical insight into the design principle of all-in-one hydrogels with outstanding mechanical and adhesive properties and can potentially enhance the efficacy of hydrogel adhesives for wound healing.

RESUMEN

BACKGROUND: Chylous ascites or chyloperitoneum can be caused by peroperative injury of the lymphatic pathways; the lymph is accumulated in the abdominal cavity. The incidence of chylous ascites varies according to the type of surgery and the extent of the lymphadenectomy. The first choice of treatment is a conservative procedure - total parenteral nutrition or a strict low-fat diet. If this fails, a surgical revision is indicated. However, this is often difficult due to postoperatively altered terrain and the chronic presence of pathological secretion in the abdominal cavity. The application of a fat emulsion or indocyanine green (ICG) to the lymphatic drainage area may help identify the lymph source. Nowadays, ICG is used in various clinical indications, e.g. evaluation of liver function, angiography in ophthalmology, assessment of blood supply to the tissues, search for lymph nodes in oncological surgeries. The advantage of ICG lymphography is the possibility of observing the source of the leak in real time directly during surgical revision. CASE REPORT: A polymorbid 66-year-old patient after radical oncogynaecological surgery with aortopelvic lymphadenectomy was postoperatively complicated by persistent, high-volume chylous ascites, not responding to conservative treatment. Therefore, we performed surgical revision of the abdominal cavity and successful treatment of the leak source using ICG peroperative lymphography and subsequent application of Vivostat autologous tissue glue to this area. CONCLUSION: High-volume consistent chylous ascites is not a frequent postoperative complication but it has a significant impact on the quality of life, nutritional status of the patient and further patient prognosis. The treatment is strictly individual. The first choice should be a conservative approach. Where that fails, a difficult surgical revision is indicated. Today, however, the surgeon can be helped by modern technologies such as fluorescent navigated surgery or treatment of the source with autologous tissue adhesives. The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedice papers.

RESUMEN

BACKGROUND: Given appropriate case selection and capability, many acute lacerations can be managed in the primary care setting. An understanding of the basic pathophysiology, assessment and management principles is essential. OBJECTIVE: The aim of this article is to provide a basic framework for assessing and managing simple acute lacerations. DISCUSSION: The aim of assessment is initially to decide whether the laceration is suitable for office-based treatment, and then whether it requires formal surgical closure with sutures or staples. Two non-surgical techniques for skin closure in amenable wounds are described. A companion article in this issue provides details of surgical closure techniques and wound aftercare.

RESUMEN

Radiation-associated vascular changes most commonly present in the form of stenosis, thrombosis and occlusion. However, development of intracranial aneurysms secondary to radiation is far less common and often manifests with rupture. These aneurysms are difficult to treat and associated with high morbidity and mortality when ruptured compared with saccular aneurysms unrelated to radiation treatment. Both surgical and endovascular options are available for treatment of these aneurysms. We present a young patient with a radiation-induced intracranial pseudoaneurysm arising from the lenticulostriate branch of the left middle cerebral artery (MCA); this developed 1 year 4 months after 59.4 Gy of focused radiation to the suprasellar pilomyxoid astrocytoma. The patient successfully underwent endovascular glue embolization of the aneurysm and occlusion of the lenticulostriate artery after unsuccessful trapping of the aneurysm and occlusion of the parent artery using coils. She developed transient hemiparesis of the right side following the procedure, which was managed conservatively. We performed a complete review of the literature dealing with the radiation-induced intracranial aneurysms, their presentation, treatment and outcome.

RESUMEN

BACKGROUND: Traumatic lacerations to the skin represent a fairly common reason for seeking emergency department care. Although the incidence of lacerations has decreased over the past decades, traumatic cutaneous lacerations remain a common reason for patients to seek emergency department care. OBJECTIVE: Innovations in laceration management have the potential to improve patient experience with this common presentation. DISCUSSION: Studies have confirmed that delays in wound closure rarely confer increased rates of infection, although comorbidities such as diabetes, chronic renal failure, obesity, human immunodeficiency virus, smoking, and cancer should be considered. Antibiotics should be reserved for high-risk wounds, such as those with comorbidities, gross contamination, involvement of deeper structures, stellate wounds, and selected bite wounds. Topical anesthetics, which are painless to apply, have a role in select populations. In most studies, absorbable sutures perform similarly to nonabsorbable sutures and do not require revisit for removal. Novel atraumatic closure devices and expanded use of tissue adhesives for wounds under tension further erode the primacy of regular sutures in wound closure. Maintaining a moist wound environment with occlusive dressings is more important than previously thought. Most topical wound agents are of limited benefit. CONCLUSIONS: Recent innovations in wound closure are allowing emergency physicians to shift toward painless, atraumatic, and rapid closure of lacerations.

RESUMEN

OBJECTIVE: Cyanoacrylate (CYA) injection is recommended for bleeding gastric varices (GV) but with significant adverse effects. Transesophageal endoscopic ultrasound-guided therapy of large GV with a combined coil and CYA injection has shown promising results. However, it is expensive and requires technical expertise. In this study, we aimed to compare the safety and efficacy of a new method with UCYA [undiluated CYA (UCYA) followed by lipiodol-diluated CYA (DCYA)] in the management of large bleeding GV. METHODS: Fifteen consecutive patients with bleeding from large GV (>1 cm) were prospectively treated with DCYA and another 15 patients treated with UCYA retrospectively. All patients in the DCYA group underwent thoracic computed tomography scan to identify glue embolism. RESULTS: Baseline characteristics were similar between the two groups. Rates of GV obliteration and rebleeding were 100% vs 93.3% (P = 0.309) and 6.7% vs 33.3% (P = 0.06) in the DCYA and UCYA groups, respectively. One patient in the UCYA group had needle fixation which led to fatal bleeding after forceful needle extraction. In DCYA group none had glue embolism. CONCLUSIONS: Both UCYA and DCYA are effective in treating bleeding from large GV. DCYA has lower rebleeding rates and tends to have fewer adverse events than UCYA injection, although the differences are not statistically significant. Large-sample-sized prospective randomized trials are required.

RESUMEN

As lesões na face estão mais comuns na sociedade atual, envolvendo acidentes automobilísticos, quedas ou consequências iatrogênicas após procedimentos. Essas lesões podem afetar os nervos responsáveis pela musculatura facial repercutindo em alterações físicas, emocionais e psicossociais, por exemplo, no sistema estomatognático, na voz, na expressão e estética faciais, nos sentimentos e convívio social do indivíduo. Pesquisas atuais estão almejando melhores técnicas para o processo de reparo nervoso periférico e reabilitação funcional dessas lesões. As técnicas tradicionais como sutura epineural término-lateral e coaptação por meio de selante de fibrina são utilizadas com essa finalidade. O objetivo deste estudo foi avaliar a reparação do ramo bucal do nervo facial lesionado por meio da técnica términolateral de duas diferentes formas: sutura epineural e o novo selante heterólogo de fibrina, associadas ou não ao tratamento com laser de baixa potência. Foram utilizados trinta e dois ratos (Rattus norvegiccus, Wistar) com 80 dias de vida, distribuídos aleatoriamente em Grupo Controle (GC; n=8), e Grupos Experimentais (Grupo Experimental Sutura - GES e Grupo Experimental Fibrina – GEF; n=12; Grupo Experimental Sutura Laser – GESL e Grupo Experimental Fibrina Laser – GEFL; n=12). Os animais do GC não receberam intervenção cirúrgica; no GES foi realizado, no lado direito da face, a secção do ramo bucal do nervo facial, onde o coto proximal foi suturado à tela subcutânea e o coto distal suturado de forma término-lateral ao ramo zigomático do nervo facial; no GEF, no lado esquerdo da face, foram realizados os mesmos procedimentos do GES, porém foi utilizada a coaptação com selante de fibrina do coto distal. Os grupos GESL e GEFL, além das técnicas descritas, receberam tratamento com aplicação de Laser Arseneto de Gálio Alumínio (GaAlAs), pulso contínuo, comprimento de onda de 830 nm, 6 J/cm2, por 24 segundos, três vezes por semana durante cinco semanas, em três...


The injuries on the face are more common in today's society, involving motor vehicle accidents, falls or iatrogenic consequences after procedures. These injuries can affect the nerves responsible for facial muscles reflecting in physical, emotional and psychosocial changes, for example in the stomatognathic system, in voice, facial expression and aesthetics, feelings and social life of the individual. Current researches are aiming best techniques to the process of peripheral nerve repair and functional rehabilitation of these injuries. Traditional techniques such as end-to-side epineural suture coaptation by fibrin sealants are used for this purpose. The objective of this study was to evaluate the repair of buccal branch of the facial nerve injured by end-toside technique in two different ways: epineural suture and the new heterologous fibrin sealant, associated or not to treatment with low power laser. Thirty-two rats (Rattus norvegicus, Wistar) were used. They were 80 days old and were randomly divided into Control Group (CG, n=8) and Experimental Groups (Experimental Suture Group – ESG and Experimental Fibrin Group - EFG; n=12; Experimental Suture Laser Group – ESLG and Experimental Fibrin Laser Group - EFLG; n=12). The CG animals did not receive surgery; the ESG was performed on the right side of the face, the section of the buccal branch of the facial nerve, where the proximal stump was sutured to the subcutaneous tissue and the distal stump sutured end-to-side portion of the zygomatic branch of the facial nerve; EFG on the left side of the face, the same procedures were carried ESG, but was used coaptation with fibrin sealant of the distal stump. The groups ESLG and EFLG, and the techniques described, have been treated with the application of Laser Gallium Aluminum Arsenide (GaAlAs), continuous pulse, wave length 830 nm, 6J /cm2 for 24 seconds, three times per week for five weeks, at three points of the local operated from both sides. It also...

RESUMEN

INTRODUCTION: Circumcision is the most commonly performed surgical procedures in male children. Maine is one of 18 states in the United States which does not pay for neonatal circumcisions. The aim of this study was to perform outcomes and cost analysis of a sutureless circumcision technique versus circumcision using sutures. Specifically, we evaluated Dermaflex (2-octyl cyanoacrylate, 2-OCA) surgical glue circumcision as a cost effective, faster, and safe alternative to traditional suture circumcision. MATERIALS AND METHODS: Our study was a non-randomized series. We collected the operative details prospectively, abstracted clinical outcomes retrospectively, and performed data analysis retrospectively. One hundred and twenty-six circumcisions were performed by two pediatric urologists over a 1 year period. Suture circumcisions were performed exclusively during the first 6 months, and 2-OCA glue circumcisions were performed during the second 6 months. Billing charges were analyzed to extrapolate variable costs between the two surgical procedures. The technique used to perform the sutureless circumcision was a modification of the standard sleeve technique, with the use of monopolar diathermy instead of scalpel, and application of 2-OCA glue to approximate tissue edges. RESULTS: From Jan 2013 to Jan 2014, 72 patients underwent circumcision with suture, and 54 patients underwent circumcision with 2-OCA glue. Mean age in the glue group was 61 months (range 8-202 months), and 50 months in the suture group (range 5-215 months), p = 0.19. All cases were performed under general anesthesia, as outpatient surgery. Mean operative cut time was 18.4 min for the glue group, and 28.6 min for the suture group (p < 0.01). The 10.2 min operative time difference translated to a $378 cost savings per glue circumcision case. Complication rates were not statistically significant between the two groups. CONCLUSION: The use of 2-OCA tissue adhesive for sutureless circumcision is an alternative to the standard technique. It results in faster operative times, with a significant cost savings, while maintaining comparable complication rates to the standard suture technique. This is a viable, less expensive surgical option for patients whose circumcisions are not covered by Medicaid.

RESUMEN

BACKGROUND: Optimal wound healing in negative pressure wound therapy (NPWT) depends on a properly sealed vacuum system. Anatomically difficult wounds disrupt the adhesive dressing, resulting in air leaks that impair the integrity of this system. Several techniques have been used in previous reports to prevent air leaks, including the addition of skin adhesives (eg, Skin-Prep [Smith and Nephew, St. Petersburg, FL] or compound tincture of benzoin), hydrocolloid dressings, silicone, and stoma paste. The purpose of this case report is to demonstrate the effectiveness of using a cyanoacrylate tissue adhesive, dermaFLEX (FLEXCon, Spencer, MA), in maintaining an airtight, durable seal in NPWT. MATERIALS AND METHODS: The authors present a patient with a difficult to manage anogenital wound where efforts to maintain an airtight seal in NPWT proved difficult. It was decided during the course of treatment to use the cyanoacrylate tissue adhesive to create an airtight, durable seal. The tissue adhesive was applied circumferentially to the skin surrounding the wound edge. After placement of vacuum-assisted closure foam over the wound, the adhesive dressing was applied with its edges overlapping the skin area where the tissue adhesive was applied. RESULTS: The size of the wound was visibly reduced at each dressing change. An airtight seal was consistently maintained for 3 days at a time, surviving the difficult environment of the wound and maximizing the life of each adhesive dressing. CONCLUSION: For wounds in anatomically challenging locations, the use of the tissue adhesive appears to be a safe and viable option in creating a durable seal in NPWT.

RESUMEN

OBJECTIVE: To evaluate the behavior of castor oil-derived polyurethane as a hemostatic agent and tissue response after abdominal aortic injury and to compare it with 2-octyl-cyanoacrylate. METHODS: Twenty-four Guinea Pigs were randomly divided into three groups of eight animals (I, II, and III). The infrarenal abdominal aorta was dissected, clamped proximally and distally to the vascular puncture site. In group I (control), hemostasis was achieved with digital pressure; in group II (polyurethane) castor oil-derived polyurethane was applied, and in group III (cyanoacrylate), 2-octyl-cyanoacrylate was used. Group II was subdivided into IIA and IIB according to the time of preparation of the hemostatic agent. RESULTS: Mean blood loss in groups IIA, IIB and III was 0.002 grams (g), 0.008 g, and 0.170 g, with standard deviation of 0.005 g, 0.005 g, and 0.424 g, respectively (P=0.069). The drying time for cyanoacrylate averaged 81.5 seconds (s) (standard deviation: 51.5 seconds) and 126.1 s (standard deviation: 23.0 s) for polyurethane B (P=0.046). However, there was a trend (P=0.069) for cyanoacrylate to dry more slowly than polyurethane A (mean: 40.5 s; SD: 8.6 s). Furthermore, polyurethane A had a shorter drying time than polyurethane B (P=0.003), mean IIA of 40.5 s (standard deviation: 8.6 s). In group III, 100% of the animals had mild/severe fibrosis, while in group II only 12.5% showed this degree of fibrosis (P=0.001). CONCLUSION: Polyurethane derived from castor oil showed similar hemostatic behavior to octyl-2-cyanoacrylate. There was less perivascular tissue response with polyurethane when compared with cyanoacrylate.

RESUMEN

OBJECTIVES: Watertight dural closure is imperative after neurosurgical procedures because inadequately treated leakage of cerebrospinal fluid (CSF) can have serious consequences. In this study, the authors test the use of a new gelatin glue as a dural sealant in in vitro and in vivo canine models of transdural CSF leakage. METHODS: The in vitro model was sutured semicircles of canine dura mater and artificial dural substitute. The sutures were sealed with gelatin glue (n  =  20), fibrin glue (n  =  20), or a polyethylene glycol (PEG)-based hydrogel sealant (n  =  20). Each sample was set in a device to measure water pressure, and pressure was increased until leakage occurred. Bonding strength was subjectively evaluated. The in vivo model was dogs who underwent dural excision and received either no sealant (control group; n  =  5) or gelatin glue sealant (n  =  5) before dural closure. Twenty-eight days post-surgery, the maximum intracranial pressure was measured at the cisterna magna using Valsalva maneuver and tissue adhesion was evaluated. RESULTS: The water pressure at which leakage occurred in the in vitro model was higher with gelatin glue (76·5 ± 39·8 mmHg) than with fibrin glue (38·3 ± 27·4 mmHg, P < 0·001) or the PEG-based hydrogel sealant (46·3 ± 20·9 mmHg, P  =  0·007). Bonding strength was higher for the gelatin glue than fibrin glue (P < 0·001) or PEG-based hydrogel sealant (P  =  0·001). The maximum intracranial pressure in the in vivo model was higher for the gelatin glue group (59·0 ± 2·2 mmHg) than the control group (13·8 ± 4·0 mmHg, P < 0·001). Tissue adhesion was lower for the gelatin glue group than the control group (P  =  0·005). DISCUSSION: The new gelatin glue provides an effective watertight closure when used as an adjunct to sutured dural repair.

RESUMEN

Introducción El uso de adhesivos tisulares puede ser una alternativa a la sutura en la fijación de la malla, pero su experiencia clínica es muy limitada. Material y métodos Estudio prospectivo y descriptivo en un grupo de 35 pacientes con hernias inguinales operados mediante hernioplastia sin sutura (20 vía abierta y 15 vía endoscópica); la prótesis se fijó con adhesivo sintético (n-hexil-α-cianoacrilato). Este grupo se ha comparado con uno control operado mediante hernioplastia utilizando suturas. Todos los pacientes seguían protocolo de cirugía mayor ambulatoria. Se han registrado variables peri- y postoperatorias. El seguimiento se realizó a la semana, al mes, a los 6 meses y al año. Resultados No ha existido morbilidad asociada con el uso del adhesivo tisular. Durante una mediana de 15 meses no se han detectado complicaciones ni recurrencias. En la hernioplastia abierta el uso del adhesivo disminuye de forma significativa el tiempo quirúrgico (30min versus 62min, p=0,001), el dolor postoperatorio (de 2,4 a 4,5 a la semana, p < 0,001) y el consumo de analgésico (de 7 a 14 días, p < 0,001). En el abordaje laparoscópico se demuestran diferencias significativas a favor del adhesivo en el dolor (p=0,001 a las 24h) y consumo de analgésicos (p <0,001). El análisis económico demuestra un ahorro anual de 117.461,2 euros (sobre 460 hernias).Conclusión El uso de un adhesivo tisular sintético (n-hexil-α-cianocrilato) es seguro como medio de fijación en las hernioplastias no complejas en pacientes sin comorbilidad, con buenos resultados postoperatorios (AU)


Introduction: The purpose of this study was to analyse the relationship between preoperative serum levels of vitamin D and postoperative hypocalcaemia after total thyroidectomy. Material and methods: A prospective observational study was conducted on 113 patients treated by total thyroidectomy due to benign disease. Preoperative vitamin D serum levels and postoperative albumin-corrected calcium and parathormone (PTH) levels were determined. Sensitivity, specificity, positive predictive value and negative predictive value ofvitamin D and PTH levels, respectively, in the diagnosis of postoperative hypocalcaemia were calculated. Results: Hypocalcaemia was diagnosed in 44 (38.9%) patients. Vitamin D levels were signifi-cantly higher in the group of patients with normal postoperative calcium (median: 25.4 pg/mL; range: 4-60), compared to those who developed hypocalcaemia (median: 16.4 pg/mL; range: 6.3-46.9) (P = .001). Postoperative hypocalcaemia was more frequent in patients with vitamin D < 30 ng/mL (39/78) (50%), than among those with normal levels (5/35) (14.2%)(P = .001). Sensitivity, specificity, positive predictive value and negative predictive value were 88% and 68%, 43% and 82%, 50% and 71%, and 85% and 80% for vitamin D and PTH, respectively. Vitamin D and PTH showed independent prognostic values on the risk of hypocalcaemia. The OR associated with vitamin D < 30 ng/mL was 4.25 (95% CI: 1.31-13.78)(P = .016), and the OR of PTH < 13 pg/mL was 15.4 (95% CI: 4.83-49.1) (P < .001).Conclusion: Vitamin D deficiency is a risk factor of hypocalcaemia after total thyroidectomy for benign goitre. The vitamin D level provides independent prognostic information, which his complementary to that given by PTH (AU)

RESUMEN

BACKGROUND: Dentin hypersensitivity (DH) is a painful, exaggerated response to normal stimuli, such as cold, sweetness, and brushing. The aim of the present controlled, randomized, double-masked, non-inferiority clinical trial is to evaluate the effectiveness of cyanoacrylate in the treatment of DH when compared to the application of low-intensity laser. METHODS: The study includes 434 sensitive teeth from 62 patients. A total of 216 teeth were treated with laser and 218 with cyanoacrylate. A numeric rating scale was used to record the parameters of pain related to the stimuli at baseline and after the treatment at intervals of 24 hours and 30, 90, and 180 days. RESULTS: Both groups had significant reductions in DH. However, there was no significant difference between the two groups ≤6 months. Intragroup analysis showed that the effect of cyanoacrylate obtained at 24 hours remained for 90 days in response to air-jet test and 30 days for cold-spray test. There was a statistically significant difference between all other intragroup comparisons at the time intervals (P <0.001). CONCLUSIONS: It was concluded that cyanoacrylate is as effective as low-intensity laser in reducing DH. In addition, it is a more accessible and low-cost procedure and can be safely used in the treatment of DH.

RESUMEN

PURPOSE: The use of fibrin sealant (FS) (Tisseel™) for mesh fixation in patients undergoing laparoscopic groin hernia surgery is a well-recognised technique in Europe, but no study to date has examined effect on quality of life (QoL) on patients undergoing FS mesh fixation. A prospective study was therefore conducted to examine the effects on QoL of patients undergoing laparoscopic groin hernia surgery using FS in the United Kingdom. MATERIALS AND METHODS: Between March 2007 and January 2011, all patients undergoing laparoscopic total extra preperitoneal (TEP) groin hernia repair using FS were included in the study. A validated hernia questionnaire from The Royal College of Surgeons of England supplemented by the EORTC QLQ C-30 to assess the pre- and postoperative QoL, pain scores and health outcome measures was used. All the patient's demographics, duration of surgery, size of hernia, recurrence, morbidity and hospital stay were recorded. RESULTS: Data from 92 patients (87 males and 5 females) with a median age of 46 years (range, 19-82 years) was collected for the study (response rate of 92/121, 73 %). A total of 58 patients (63 %) had a unilateral and 34 patients (37 %) a bilateral hernia repair, of which 6 (7 %) were recurrent inguinal hernia. The mean operating time for a unilateral hernia was 36 min (30-62), and that for a bilateral hernia was 59 min (51-83). There were no conversions to open surgery out of the 92 patients included with the recorded morbidity of 7 %. There were no early recurrences. Eighty-nine patients (98 %) of patients were discharged in the first 24 h after surgery. There was a significant statistical difference recorded in patients visual analogue pain score (VAS 0-10) before and after surgery (P < 0.0001, Mann-Whitney U test). The physical, emotional, social and health components of the questionnaire were statistically significant pre- and postoperatively (P < 0.001 Mann-Whitney U test). CONCLUSION: Groin hernia TEP repair with FS fixation did not have a detrimental effect on QoL and pain scores. In addition, the low early recurrence rate provided good evidence of the mesh fixation properties of FS. FS can therefore be continued to be recommended, as an alternative fixation method in laparoscopic groin hernia surgery.

RESUMEN

BACKGROUND: Despite its long history, the application of N-butyl cyanoacrylate (NBCA) has been limited compared to other materials such as particulate agents and coils. This possibly owes to a widespread misconception that NBCA is difficult to handle and carries a high risk of complications due to its liquid nature and rapid polymerization time. However, recent reports have shown that, with knowledge and experience, NBCA is safe and effective to use in visceral arteries. PURPOSE: To review the outcome of transcatheter embolization of the renal artery using NBCA for varied etiologies in the kidney. MATERIAL AND METHODS: Fourteen patients with varied etiologies in the kidney underwent renal artery embolization using NBCA as the sole embolic agent (64%) or in combination with an additional embolic material (36%). A review of medical charts and images were performed to gather information regarding underlying etiologies, clinical presentation, and outcome of embolization. RESULTS: Technical success was achieved in all patients (100%) while clinical success was achieved in 12 (85.7%). One failed case was managed by repeat embolization using microcoils, while the other underwent partial nephrectomy after failed reattempt at embolization. Three patients with recurrent bleeding after previously having undergone embolization using microcoils or gelatin sponge particles were successfully managed the second time using NBCA. NBCA embolization was also effective in three patients with hemostatic abnormality. Complications attributable to NBCA embolization were renal atrophy in one patient and microcatheter tip fracture in another. CONCLUSION: The application of NBCA for transcatheter embolization of varied etiologies involving the renal artery is feasible and safe in the hands of an experienced interventional radiologist. It offers immediate and effective occlusion of the pathologic vessel and, while it can be used exclusively on its own, it can also be used to complement other embolic materials.
