ABSTRACT

OBJECTIVE@#To explore the clinical efficacy and safety of manual therapy combined with posterior percutaneous endoscopic cervical decompression(PECD) in the treatment of intractable cervical spondylotic radiculopathy.@*METHODS@#From May 2016 to May 2018, 23 CSR patients who responded poorly to conservative treatment for at least 6 weeks underwent the combination management. Firstly, the patients received the posterior percutaneous endoscopic cervical decompression routine care for the following 4 weeks and manual therapy for another 4 weeks. A total of 23 patients were followed up, including 14 males and 9 females, the age ranged from 29 to 78 years old with an average of (50.30±12.28) years, the course of disease was 3 to 24 months with an average of (9.74±5.76) months. The lesion segment involved C4,5 in 4 cases, C5,6 in 13 cases, C6,7 in 6 cases. The visual analogue scale (VAS), neck disability index (NDI), changes of cervical physiological curvature and interbody stability, adverse events were observed before and after operation. The follow-up time points were before operation, 1 day after operation and 1, 3 and 6 months after operation.@*RESULTS@#All patients successfully completed the operation and manual treatment for 4 to 8 times. Among the 29 cases, 23 patients were followed up for more than 6 months. There was no spinal cord and nerve root injury during the treatment and follow-up. Operation time was from 80 to 120 min with a median of 90 min;intraoperative blood loss was from 35 to 80 ml with a median of 50 ml. NDI, VAS of neck, shoulder and arm each period after operation were significantly lower than those before PECD(P<0.05), while there were no significant improvement in cervical physiological curvature and target segment intervertebral space height(P>0.05);there was no significant change in interbody stability (P>0.05). After received the manual therapy, NDI significantly decreased (P<0.05), however, there was no significant difference in VAS of neck, shoulder and arm, physiological curvature of cervical spine and intervertebral space height of target segment compared with that before manual treatment (P>0.05);there was no significant change in interbody stability (P>0.05).@*CONCLUSION@#Manual therapy combined with PECD in the treatment of intractable cervical spondylotic radiculopathy can not only quickly improve the symptoms, but also alleviate the residual symptoms after PECD safely and effectively, and can not cause obvious signs of accelerated instability of cervical adjacent segments in the short term.

ABSTRACT

Introducción: el quiste dentígero, también conocido como quiste folicular, es la segunda forma más habitual de los quistes de la región maxilar después del quiste radicular. Tiene una incidencia del 20% con respecto a todos los quistes odontogénicos y se encuentra más en el género masculino entre los 20-40 años. El manejo conservador en lesiones quísticas de gran tamaño es indispensable para evitar defectos óseos o daño a estructuras vecinas. Sin embargo, en lesiones de menor tamaño, la enucleación continúa siendo el tratamiento de elección. Objetivo: presentar un caso clínico de un quiste dentígero y hacer una revisión de la literatura actualizada. Caso clínico: paciente masculino de 23 años que presentó aumento de volumen en zona geniana derecha y, además, en su ortopantomografía se observó una lesión en el sector de los incisivos superiores. Se realizó enucleación de la lesión, cuyo diagnóstico histológico previo fue quiste dentígero y posteriormente se obtiene una correcta regeneración ósea tras un año de seguimiento Conclusión: el manejo del quiste dentígero es variado: puede ir desde la enucleación quirúrgica hasta la descompresión y marsupialización del mismo. No obstante, todos los tratamientos actuales se basan en contrarrestar los factores de expansión quística que permiten a esta lesión alcanzar grandes tamaños intraóseos y poder causar desde rizolisis de dientes adyacentes hasta una asimetría facial como sucedió en este caso clínico.


Introduction: The dentigerous cyst, also known as a follicular cyst, is the second most common form of cysts of the maxillary region after the radicular cyst. It has an incidence of 20% with respect to all odontogenic cysts, it is found more in the male gender between 20-40 years of age. Conservative management of large cystic lesions is essential to avoid bone defects or damage to neighboring structures. However, in smaller lesions, enucleation continues to be the treatment of choice. Objective: To present a clinical case of a dentigerous cyst and to review the updated literature. Clinical case: A 23-year-old male patient who presented increased volume in the right genital area and his orthopantomography showed a lesion in the upper incisor sector. Enucleation of the lesion was performed, whose previous histological diagnosis was dentigerous cyst and later a correct bone regeneration was obtained after one year of follow-up. Conclusion: The management of the dentigerous cyst is varied, it can range from surgical enucleation to decompression and marsupialization. However, all current treatments are based on counteracting cystic expansion factors that allow this lesion to reach large intraosseous sizes and can cause from rhizolysis of adjacent teeth to facial asymmetry, as happened in this clinical case.

ABSTRACT

Introdução: os cistos radiculares são as lesões císticas mais comuns nos maxilares. Eles surgem dos Restos Epiteliais de Malassez, presos no ligamento periodontal e podem ser ativados por um processo inflamatório na região pulpar. Geralmente são descobertos em exames radiográficos de rotina, apresentando-se como uma imagem radiolúcida, bem delimitada, envolvendo o periápice de um ou mais dentes. Objetivo: apresentar o tratamento de um extenso cisto radicular, em região de maxila, com acompanhamento de 18 meses. Relato do caso: Paciente do sexo feminino, 49 anos, foi encaminhada para avaliação e tratamento na Clínica Odontológica da Faculdade Sete Lagoas (FACSETE), apresentando lesão extensa em região maxilar anterior direita ao exame radiográfico. Ao exame clínico, observou-se leve assimetria facial e ausência de sintomas dolorosos. Tomografia computadorizada, punção aspirativa e biópsia incisional foram utilizadas para se chegar ao diagnóstico compatível com cisto radicular. Optou-se por uma técnica conservadora, em que foi realizada a descompressão da lesão. Após 05 meses de tratamento, um novo procedimento cirúrgico foi realizado para enuclear o restante da patologia. Conclusão: a descompressão, com utilização de cânula, é um tratamento auxiliar fácil, conservador, eficaz e reduz a morbidade causada por diferentes cistos odontogênicos(AU)


Introduction: root cysts are the most common cystic lesions in the jaw. They arise from the Epithelial Remains of Malassez, trapped in the periodontal ligament and can be activated by an inflammatory process in the pulp region. They are usually discovered in routine radiographic examinations, presenting as a well-defined radiolucent image involving the periapex of one or more teeth. Objective: to present the treatment of an extensive root cyst, in the maxillary region, with a follow-up of 18 months. Case report: A 49-year-old female patient was referred for evaluation and treatment at the Dental Clinic of Faculdade Sete Lagoas (FACSETE), with an extensive lesion in the right anterior maxillary region on radiographic examination. On clinical examination, mild facial asymmetry and absence of painful symptoms were observed. Computed tomography, aspiration puncture and incisional biopsy were used to reach a diagnosis compatible with radicular cyst. We opted for a conservative technique, in which the lesion was decompressed. After 05 months of treatment, a new surgical procedure was performed to enucleate the rest of the pathology. Conclusion: decompression, using a cannula, is an easy, conservative, effective auxiliary treatment and reduces the morbidity caused by different odontogenic cysts.

ABSTRACT

Abstract Objective To compare pain, function, quality of life and adverse events of lumbar decompression and spinal fusion in patients with degenerative spinal pathologies who participated in a second opinion program for spinal surgeries with a 36-month followup. Methods The data for this retrospective cohort were withdrawn from a private healthcare system between June 2011 and January 2014. The study sample consisted of 71 patients with a lumbar spine surgical referral. The outcomes for the comparisons between lumbar decompression and spinal fusion were quality of life (evaluated through the EuroQoL 5D), pain (measured by the Numerical Rating Scale) and function (assessed through the Roland Morris Disability Questionnaire) measured at baseline, and at 12 and 36 months after the surgical procedures. The definitions of recovery were established by the minimal clinically important difference (MCID). The baseline differences between the groups were analyzed by non-paired t-test, and the differences in instrument scores between time points, by generalized mixed models. The results were presented as mean values adjusted by the models and 95% confidence intervals. Results Concerning the surgical techniques, 22 patients were submitted to spinal fusion and 49 patients, to lumbar decompression. As for the comparisons of the findings before and after the surgical interventions, the MCID was achieved in all outcomes regarding quality of life, pain and function at both time points when compared to baseline scores Moreover, concerning the complication rates, only lumbar decompression presented a surgical rate of 4% (n = 3) for recurrence of lumbar disc hernia. Conclusion Patients with degenerative spinal pathologies present improvements in long-term outcomes of pain, function and quality of life which are clinically significant, no matter the surgical intervention.


Resumo Objetivo Comparar a dor, a função, a qualidade de vida e os eventos adversos da descompressão lombar e da fusão espinhal em pacientes com patologias degenerativas da coluna vertebral que participaram de um programa de segunda opinião para cirurgias de coluna com acompanhamento de 36 meses. Métodos Os dados desta coorte retrospectiva foram obtidos de um sistema de saúde privado entre junho de 2011 e janeiro de 2014. A amostra do estudo foi composta por 71 pacientes encaminhados para cirurgia de coluna lombar. Os desfechos para comparações entre a descompressão lombar e a fusão espinhal foram qualidade de vida (avaliada pelo questionário EuroQoL 5D), dor (medida pela Escala Numérica de Classificação de Dor) e função (avaliada pelo Questionário de Incapacidade de Roland Morris) no início do estudo e aos 12 e 36 meses de acompanhamento pós-cirúrgico. As definições de recuperação foram estabelecidas pela diferença mínima clinicamente importante (DMCI). As diferenças basais entre os grupos foram analisadas por teste t não pareado, e as diferenças nas pontuações dos instrumentos entre os momentos, por modelos mistos generalizados. Os resultados foram apresentados como valores médios ajustados pelos modelos e intervalos de confiança de 95%. Resultados No total, 22 pacientes foram submetidos à artrodese, e 49 pacientes, à descompressão lombar. Quanto às comparações de achados antes e depois das intervenções cirúrgicas, a DMCI foi alcançada em todos os desfechos de qualidade de vida, dor e função nos dois pontos de acompanhamento em relação aos escores basais Em relação às complicações, apenas a descompressão lombar apresentou 4% (n = 3) de taxa cirúrgica de recidiva da hérnia de disco lombar. Conclusão Pacientes com patologias espinhais degenerativas apresentam melhoras nos desfechos de dor, função e qualidade de vida em longo prazo que são clinicamente significativas e independentes da intervenção cirúrgica.

ABSTRACT

ABSTRACT Background: Peripheral neural surgical decompression (PNSD) is used as a complementary therapy to the clinical treatment of neuritis to preserve neural function. Objective: To evaluate the long-term (≥ 1 year) clinical and functional results for PNSD in leprosy neuritis. Methods: This cross-sectional study included leprosy patients who were in late postoperative period (LPO) of surgical decompression of ulnar, median, tibial, and fibular nerves. Socioeconomic, epidemiological, and clinical data were collected. The following instruments were used in this evaluation: visual analogue pain scale (VAS), Douleur Neuropathique en 4 Questions (DN4), SALSA scale, and simplified neurological assessment protocol. The preoperative (PrO) and 180-day postoperative (PO180) results were compared. Results: We evaluated 246 nerves from 90 patients: 56.6% were on multidrug therapy (MDT) and 43.3% discharged from MDT. Motor scores and pain intensity showed statistically significant improvement (p<0.01). There was an increase in sensory scores only for bilateral ulnar nerves (p<0.05). Of the operated cases, 26.0% of patients were referred for surgery of ulnar neuritis and 23.6% of tibial neuritis. Neuropathic pain was reported in 41% of cases. Daily dose of prednisone reduced from 39.6 mg (±3.0) in PrO, 16.3 mg (±5.2) in PO180, to 1.7 mg (±0.8) in LPO. The SALSA scale results showed mild activity limitation in 51% and moderate in 34% of patients. Eighty percent of individuals reported that the results reached their expectations. Conclusions: PNSD in leprosy was effective in the long term to decrease the prevalence and intensity of pain, improve motor function, and reduce the dose of corticosteroids, which is reflected in the patients' satisfaction.


RESUMO Antecedentes: A descompressão cirúrgica neural periférica (DCNP) é usada como uma terapia complementar ao tratamento clínico da neurite hansênica para preservar a função neural. Objetivo: Avaliar a longo prazo (≥ 1 ano) os resultados clínicos e funcionais da DCNP na neurite hansênica. Métodos: Este estudo transversal incluiu pacientes que estavam no pós-operatório tardio (POT) de cirurgia de descompressão dos nervos ulnares, medianos, tibiais e fibulares. Foram coletados dados socioeconômicos, epidemiológicos e clínicos. Os instrumentos utilizados foram: escala visual analógica de dor (EVA), questionário de dor neuropática 4 (DN4), escala SALSA e protocolo de avaliação neurológica simplificada. Os resultados obtidos foram comparados com os do pré-operatório (PrO) e pós-operatório de 180 dias (PO180). Resultados: Foram avaliados 246 nervos de 90 pacientes: 56,6% estavam em poliquimioterapia (PQT) e 43,3% em alta da PQT. Escores motores e intensidade da dor apresentaram melhora significante (p<0,01). Houve aumento nos escores sensitivos nos nervos ulnares bilaterais (p<0,05). Neurite ulnar foi indicação cirúrgica em 26,0% dos casos operados, seguida pela neurite tibial (23,6%). Dor neuropática foi relatada em 41% dos casos. Dose diária de prednisona reduziu de 39,6 mg (±3,0) na PrO, 16,3 mg (±5,2) na PO180, para 1,7 mg (±0,8) na POT. Escala SALSA mostrou limitação leve da atividade em 51% e moderada em 34% dos pacientes. 80% dos indivíduos relataram que os resultados atingiram suas expectativas. Conclusão: DCNP na hanseníase foi eficaz a longo prazo na redução da prevalência e intensidade da dor, na melhora da função motora e redução da dose de corticosteroides, refletindo na satisfação do paciente.

ABSTRACT

La neuralgia del trigémino es un trastorno neuropático paroxístico que afecta a una o varias de las ramas sensoriales del nervio trigémino cuya etiología es variada, la más aceptada es por compresiones vasculares a nivel del ángulo ponto cerebeloso que generan conflicto de espacio. Dentro de las posibilidades de tratamiento, la descompresión microvascular permite la cura fisiopatológica de la neuralgia del trigémino, teniendo resultados satisfactorios a corto/largo plazo, y bastantes ventajas en comparación a otras técnicas de mínima invasión. Se presenta el caso de una paciente con tratamiento médico máximo no efectivo, a la cual se realizó descompresión microvascular evidenciando conflicto arterial y venoso con el nervio.


Trigeminal neuralgia is a paroxysmal neuropathic disorder that affects one or more of the sensory branches of the trigeminal nerve, the etiology of which is varied, the most accepted being due to vascular compressions at the level of the brainstem that generate conflict of space. Within the treatment possibilities, microvascular decompression allows the pathophysiological cure of trigeminal neuralgia, having satisfactory results in the short / long term, and many advantages compared to other minimally invasive techniques. We present the case of a patient with maximum ineffective medical treatment, who underwent microvascular decompression, showing arterial and venous conflict with the nerve.

ABSTRACT

ABSTRACT Objective: To verify the effectiveness of indirect decompression after lateral access fusion in patients with high pelvic incidence. Methods: A retrospective, non-comparative, non-randomized analysis of 22 patients with high pelvic incidence who underwent lateral access fusion, 11 of whom were male and 11 female, with a mean age of 63 years (52-74), was conducted. Magnetic resonance exams were performed within one year after surgery. The cross-sectional area of the thecal sac, anterior and posterior disc heights, and bilateral foramen heights, measured pre- and postoperatively in axial and sagittal magnetic resonance images, were analyzed. The sagittal alignment parameters were measured using simple radiographs. The clinical results were evaluated using the ODI and VAS (back and lower limbs) questionnaires. Results: In all cases, the technique was performed successfully without neural complications. The mean cross-sectional area increased from 126.5 mm preoperatively to 174.3 mm postoperatively. The mean anterior disc height increased from 9.4 mm preoperatively to 12.8 mm postoperatively, while the posterior disc height increased from 6.3 mm preoperatively to 8.1 mm postoperatively. The mean height of the right foramen increased from 157.3 mm in the preoperative period to 171.2 mm in the postoperative period and that of the left foramen increased from 139.3 mm in the preoperative to 158.9 mm in the postoperative. Conclusions: This technique is capable of correcting misalignment in spinal deformity, achieving fusion and promoting the decompression of neural elements. Level of evidence III; Retrospective study.

ABSTRACT

Abstract Degenerative lumbar spinal stenosis is the most frequent cause of low back pain and/or sciatica in the elderly patient. Epidemiology, pathophysiology, clinical manifestations and testing are reviewed in a wide current bibliographic investigation. The importance of the relationship between clinical presentation and imaging study, especially magnetic resonance imaging (MRI), is emphasized. Prior to treatment indication, it is necessary to identify the precise location of pain, as well as the differential diagnosis between neurological and vascular lameness. Conservative treatment combining medications with various physical therapy techniques solves the problem in most cases, while therapeutic testing with injections, whether epidural, foraminal or facetary, is performed when pain does not subside with conservative treatment and before surgery is indicated. Injections usually perform better results in relieving sciatica symptoms and less in neurological lameness. Equine tail and/or root decompression associated or not with fusion is the gold standard when surgical intervention is required. Fusion after decompression is necessary in cases with segmental instability, such as degenerative spondylolisthesis. When canal stenosis occurs at multiple levels and is accompanied by axis deviation, whether coronal and/or sagittal, correction of axis deviations should be performed in addition to decompression and fusion, especially of the sagittal axis, in which a lumbar lordosis correction is required with techniques that correct the rectified lordosis to values close to the pelvic incidence.


Resumo A estenose degenerativa do canal vertebral lombar é a causa mais frequente de dor lombar e/ou ciática no paciente idoso; sua epidemiologia, fisiopatogenia, manifestações e testes clínicos são revistos em ampla investigação bibliográfica atual. A importância da relação entre a clínica e o estudo por imagens, principalmente a ressonância magnética (RM), é ressaltada. Antes da indicação do tratamento, é necessário identificar a localização precisa da dor, bem como o diagnóstico diferencial entre a claudicação neurogênica e a vascular. O tratamento conservador associando medicações com as diversas técnicas fisioterápicas resolve o problema na maioria dos casos, já o teste terapêutico com os bloqueios, seja epidural, foraminal ou facetário, é realizado quando as dores não cedem com o tratamento conservador e antes da indicação da cirurgia. Os bloqueios costumam dar melhores resultados no alívio dos sintomas de ciatalgia e menos no quadro de claudicação neurogênica. A descompressão da cauda equina e/ou radicular associada ou não à artrodese é o padrão ouro quando a intervenção cirúrgica é necessária. A artrodese após a descompressão é necessária nos casos com instabilidade segmentar, como na espondilolistese degenerativa. Quando a estenose de canal acontece em múltiplos níveis e vem acompanhada de desvio de eixo, seja coronal e/ou sagital, deve ser realizada, além das descompressões e artrodese, a correção dos desvios de eixo, principalmente o eixo sagital, quando a correção da lordose lombar se impõe com técnicas que corrigem a lordose retificada para valores próximos à incidência pélvica.

ABSTRACT

OBJECTIVE@#To investigate the short-term clinical effect of double channel decompression and bone grafting through the greater trochanter combined with allograft fibula propping in the treatment of osteonecrosis of femoral head (ONFH).@*METHODS@#Twenty two patients (23 hips) with osteonecrosis of the femoral head were included from November 2017 to February 2019. According to Association Research Cirulation Osseous(ARCO) staging, there were 13 hips at stageⅡgroup, aged from 20 to 48 years old with an average of(32.5±8.5)years old;10 hips at stageⅢgroup, aged from 18 to 45 years old with an average of(32.7±8.6) years old. A single approach through the greater trochanterwas used for decompression, bone grafting and fibula support. Harris scoring system was used to evaluate the function of hip joint before and after implantation, and the anteroposterior and lateral X-ray films of hip joint were taken at 3, 6, 12 and 18 months after implantation to observe and analyze the progress of femoral head necrosis and regeneration.@*RESULTS@#All patients were followed up, and the duration ranged from 12 to 18 months with an average of (14.6±2.1) months. Harris score of stageⅡand stageⅢpatients increased from 73.2± 5.5 and 66.5±3.4 to 87.6±8.7(@*CONCLUSION@#The effect of double trochanteric decompression and bone grafting combined with fibular allograft propping in the treatment of early and middle stage avascular necrosis of the femoral head is good, especially suitable for young and middle aged patients with ARCOⅡstage avascular necrosis of the femoral head.

ABSTRACT

PURPOSE@#The median time from the event leading to the spinal cord injury (SCI) to the time of decompressive surgery is estimated to be 6.9 days in Iran, which is much longer than the proposed ideal time (less than 24 h) in published guidelines. The current qualitative study aimed to determine the reasons for the observed decompression surgery delay in Iran from the perspective of neurosurgeons.@*METHODS@#This qualitative study is designed to perform content analysis on the gathered data from face-to-face semi-structured interviews with 12 Iranian neurosurgeons.@*RESULTS@#The findings of the current study suggest that patient-related factors constitute more than half of the codes extracted from the interviews. Overall, the type of injury, presence of polytrauma, and surgeons' wrong attitude are the main factors causing delayed spinal cord decompression in Iranian patients from the perspective of neurosurgeons. Other notable factors include delay in transferring patients to the trauma center, delay in availability of necessary equipment, and scarce medical personnel.@*CONCLUSION@#In the perspective of neurosurgeons, the type of injury, presence of polytrauma, and surgeons' wrong attitude are the leading reasons for delayed decompressive surgery of individuals with SCI in Iran.

ABSTRACT

ABSTRACT Purpose To evaluate the effects of controlled decompression and rapid decompression, explore the potential mechanism, provide the theoretical basis for the clinical application, and explore the new cell death method in intracranial hypertension. Methods Acute intracranial hypertension was triggered in rabbits by epidural balloon compression. New Zealand white rabbits were randomly put into the sham group, the controlled decompression group, and the rapid decompression group. Brain water content, etc., was used to evaluate early brain injury. Western blotting and double immunofluorescence staining were used to detect necroptosis and apoptosis. Results Brain edema, neurological dysfunction, and brain injury appeared after traumatic brain injury (TBI). Compared with rapid decompression, brain water content was significantly decreased, neurological scores were improved by controlled decompression treatment. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining and Nissl staining showed neuron death decreased in the controlled decompression group. Compared with rapid decompression, it was also found that apoptosis-related protein caspase-3/ tumor necrosis factor (TNF)-a was reduced markedly in the brain cortex and serum, and the expression levels of necroptosis-related protein, receptor-interacting protein 1 (RIP1)/receptor-interacting protein 1 (RIP3) reduced significantly in the controlled decompression group. Conclusions Controlled decompression can effectively reduce neuronal damage and cerebral edema after craniocerebral injury and, thus, protect the brain tissue by alleviating necroptosis and apoptosis.

ABSTRACT

Resumen El tratamiento actual para la obstrucción biliar maligna es la derivación biliar no quirúrgica con propósito paliativo. La cirugía tiene indicaciones específicas en pacientes con patología maligna con propósito curativo. Sin embargo, la obstrucción duodenal y del conducto biliar intra o extrahepático no dilatado hace que esta cirugía y el procedimiento endoscópico guiado por ultrasonografía endoscópica (USE) sean difíciles de realizar. Presentamos nuestra experiencia con el primer caso en Colombia, un país latinoamericano del tercer mundo. Consistió en una colecistogastrostomía guiada por USE, a partir de la utilización de una endoprótesis luminal (Lumen-apposing metal stents, LAMS) (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, Estados Unidos) de 15 mm × 10 mm, en un paciente masculino con cáncer pancreático inoperable e invasión duodenal con conducto colédoco dilatado. La colecistogastrostomía guiada por USE podría ser considerada como una opción de más importancia para la descompresión biliar que el drenaje percutáneo, ya que es superior en términos de viabilidad técnica, seguridad y eficacia en casos específicos de estenosis ampular e invasión duodenal. Además, puede ser realizada en países del tercer mundo, cuando se cuenta con el entrenamiento y los instrumentos adecuados. La endoprótesis metálica totalmente recubierta, aplicada a luz (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, Estados Unidos), es ideal para la colecistogastrostomía guiada por USE, a fin de minimizar complicaciones como fugas biliares. Se necesitan estudios comparativos adicionales para validar los beneficios de esta técnica.


Abstract The current treatment of malignant biliary obstruction is non-surgical biliary diversion with palliative intent. The surgery having specific indications in patients with malignant pathology with curative intent. However, duodenal obstruction and non-dilated intra- or extrahepatic bile duct make these surgical and endoscopic procedures guided by EUS difficult. We present our experience with the first case in Colombia, a third-world country in Latin America, of a cholecystogastrostomy guided by endoscopic ultrasound (EUS) in a patient with unresectable pancreatic cancer and duodenal invasion with dilated common bile duct using a luminal stent (LAMS) (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, USA) 15 mm × 10 mm. EUS-guided cholecystogastrostomy should be considered as an option for biliary decompression of greater importance than percutaneous drainage since it is superior in terms of technical feasibility, safety and efficacy in specific cases of ampullary stenosis and duodenal invasion. In addition, it can be done in third world countries when it has the appropriate training and implements. The fully covered metal stent applied to light (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, USA) is ideal for EUS guided cholecystogastrostomy to minimize complications such as bile leakage. Additional comparative studies are needed to validate the benefits of this technique.

ABSTRACT

Introdução: O objetivo do trabalho é relatar um caso de ceratocisto associado à impactação dentária, o qual foi tratado com descompressão, seguido de enucleação da lesão e utilização de solução de Carnoy. Relato de caso: Paciente do sexo masculino, 14 anos, encaminhado para avaliação de lesão encontrada após exame imaginológico de rotina. O mesmo demonstrou extensa lesão radiolúcida localizada na região de ângulo e ramo da mandíbula, com presença do elemento 48 intralesional próximo a basilar. Foi realizado biópsia incisional e instalação de dispositivo de descompressão no mesmo tempo cirúrgico, o qual o resultado histopatológico foi de ceratocisto. Após 6 meses com o dispositivo, observou-se diminuição da lesão e melhora no posicionamento do dente incluso. Frente a boa resposta à descompressão, decidiu-se pela enucleação total da lesão, exodontia dos dentes 47 e 48, curetagem rigorosa e tereapia adjuvante com aplicação da solução de Carnoy. O paciente evoluiu bem, neoformação óssea na área operada e encontra-se em acompanhamento há 6 meses, sem sinais de recidiva. Considerações finais: O uso da descompressão cirúrgica em lesões císticas mandibulares minimiza os danos as estruturas circunvizinhas, riscos de fratura patológica e lesão nervosa. Em função das altas taxas de recidiva, a terapia adjuvante após a enucleção é imprescindível para essa lesão, sendo a aplicação da solução de Carnoy uma das técnicas com melhores resultados. Dessa forma, para aumentar a taxa de sucesso e minimizar as sequelas, o planejamento cirúrgico dos ceratocistos mandibulares extensos deve ser feito de forma criteriosa e cuidadosa... (AU)


Introduction: The objective of this study is to report a case of keratocyst associated with dental impaction, which was treated with decompression, followed by enucleation lesion and Carnoy solution. Case report: Male patient, 14 years old, referred for evaluation of lesion found after routine imaging. He showed extensive radiolucent lesion located in the region of the angle and branch of the mandible, with the presence of the intralesional element 48 near the basilar. An incisional biopsy was performed and a decompression device was installed during surgical time and the histopathological result was keratocyst. After 6 months of observation a reduction of the lesion and improvement in the positioning of the tooth even were noticed. Given the good response to decompression, it was decided to complete the enucleation of the lesion, extraction of teeth 47 and 48, rigorous curettage and adjuvant therapy with Carnoy's solution. Followed up for 6 months, patient evolved well creating a new bone formation in the operated area with no signs of relapse. Final considerations: The use of surgical decompression in cystic mandibular lesions minimizes damage to surrounding structures, pathological fracture risks, and nerve damage. Because of the high rates of recurrence, keratocysts require adjuvant therapy after enucleation and Carnoy's solution is one of the best performing techniques. Thus, to increase success rate and minimize sequelae, the surgical planning of extensive mandibular keratocysts should be done carefully and judiciously... (AU)

ABSTRACT

Abstract Objective To assess the long-term outcome and perioperative morbidity in spine surgeries for lumbar degenerative disorders and, thereby, to evaluate the safety of surgery in the aging population. Methods Retrospective study of patients aged > 70 years, operated for degenerative lumbar disorders between 2011 and 2015. We evaluated patient demographic, clinical and surgical data; comorbidities, perioperative complications, pre & postoperative pain scores and Oswestry disability index (ODI) scores, patient satisfaction and overall mortality. Results A total of 103 patients (Males: Females55:48) with mean age 74.6 years (70-85yrs) were studied. 60 patients (58.2%) had decompression alone, while 43 (41.8%) had decompression & fusion. Mean hospital stay was 5.7days. Mean follow-up was 47.6months (24-73mnths). Patients reported significant improvement in backpain (Numerical pain score 7.7 vs 1.6; p < 0.001), leg pain (Numerical pain score 7.4 vs 1.7; p < 0.001), disability (ODI 82.3 vs 19.1; p < 0.001) and walking distance (p < 0.001). 76% patients were satisfied with the results at the time of final follow-up. 26 patients (25.24%) had perioperative complications which were all minor, without mortality. Most common intraoperative & postoperative complications were dural tear (6.79%) & urinary tract infection (6.79%) respectively. Conclusions With meticulous perioperative care lumbar spine surgery is safe and effective in elderly population. Patients had longer mean hospital stay in view of the gradual and comprehensive rehabilitation program. Presence of comorbidities or minor perioperative complications did not increase the overall morbidity or affect the clinical outcomes of surgery in our study.


Resumo Objetivos Avaliar o resultado no longo prazo e a morbidade perioperatória em cirurgias da coluna vertebral, devido a doenças lombares degenerativas e, assim, avaliar a segurança da cirurgia na população idosa. Métodos Estudo retrospectivo de pacientes com idade superior a 70 anos, submetidos à cirurgia em virtude de distúrbios lombares degenerativos, entre 2011 e 2015. Foram avaliados os dados demográficos, clínicos e cirúrgicos dos pacientes; comorbidades; complicações perioperatórias; escores de dor no pré e no pós-operatório; índice de incapacidade de Oswestry (ODI, na sigla em inglês); satisfação do paciente e a mortalidade geral. Resultados Foram estudados 103 pacientes (homens:mulheres, 55:48) com idade média de 74,6 anos (70 a 85 anos). 60 pacientes (58,2%) apresentaram somente descompressão, enquanto 43 (41,8%) apresentaram descompressão e fusão. O tempo médio de internação foi de 5,7 dias. O tempo médio de acompanhamento foi de 47,6 meses (24-73 meses). Os pacientes relataram melhora significativa da dor nas costas (pontuação numérica da dor 7,7 versus 1,6; p < 0,001), dor nas pernas (pontuação numérica da dor 7,4 versus 1,7; p < 0,001), incapacidade (ODI 82,3 versus 19,1; p < 0,001) e distância percorrida a pé (p < 0,001). Um total de 76% dos pacientes estavam satisfeitos com os resultados no momento do acompanhamento final. 26 pacientes (25,24%) apresentaram complicações perioperatórias, todas sem relevância e sem mortalidade. As complicações intra e pós-operatórias mais comuns foram ruptura dural (6,79%) e infecção do trato urinário (6,79%), respectivamente. Conclusões Com meticulosos cuidados perioperatórios, a cirurgia da coluna lombar é segura e eficaz na população idosa. Os pacientes tiveram um maior tempo médio de internação hospitalar, em virtude do programa de reabilitação gradual e abrangente. A presença de comorbidades ou complicações perioperatórias sem relevância, não aumentou a morbidade geral, nem afetou os resultados clínicos da cirurgia em nosso estudo.

ABSTRACT

Introdução: O ameloblastoma é uma neoplasia benigna, localmente invasiva, originada do epitélio odontogênico que ainda não possui sua etiologia esclarecida. Este tumor pode ser identificado radiograficamente como unicístico ou multicístico e geralmente, está relacionado com um dente incluso. O tratamento desta patologia do complexo maxilofacial que acomete tanto a maxila quanto a mandíbula, é baseado no diagnóstico clínico, imagens (raios x (RX), tomografia computadorizada (TC) e histopatológico. O objetivo deste trabalho é descrever e avaliar através de tomografia computadorizada (TC), o tamanho do tumor durante o período em que foi submetido à descompressão, para que as dimensões do mesmo possam ser mensuradas e comparadas em intervalos, dessa forma, comprovar a efetividade dos métodos de descompressão e marsupialização quando bem indicados.Relato de caso:No presente relato de caso, o paciente apresenta ameloblastoma unicístico de variante histológica plexiforme, conforme o exame histopatológico e está sendo tratado por meio de descompressão com a finalidade de se obter a diminuição do volume da lesão cística e consequente neoformação óssea, uma vez que a descompressão possibilita este processo. Considerações finais:O tratamento conservador pode surtir efeito tal como nesse caso em que se evidenciou a regressão do tamanho do tumor e a neoformação de estruturas ósseas antes acometidas pela patologia...

Introduction: Ameloblastoma is a benign neoplasm, locally invasive, originating from the odontogenic epithelium that still does not have a clear etiology. This tumor can be radiographically identified as unicystic or multicystic and is usually related to an included tooth. The treatment of this pathology of the maxillofacial complex that affects both the maxilla and the mandible is based on clinical diagnosis, images (x-rays (X-rays), computed tomography (CT) and histopathology. The objective of this work is to describe and evaluate using computed tomography (CT), the size of the tumor during the period in which it was subjected to decompression, so that its dimensions can be measured and compared at intervals, thus proving the effectiveness of the methods of decompression and marsupialization when well indicated. Case report: In the present case report, the patient has unicystic ameloblastoma of a plexiform histological variant, according to the histopathological examination and is being treated by means of decompression in order to obtain a decrease in the volume of the cystic lesion and consequent bone neoformation, once that decompression makes this process possible. Final considerations: The conserved treatment or it can have an effect as in this case, in which the regression of the tumor size and the new formation of bone structures that were previously affected by the pathology were evidenced...

ABSTRACT

Introducción: El hemiespasmo facial primario (HFP) se produce por la hiperexcitabilidad del nervio facial y sus núcleos de origen como consecuencia de la compresión vascular. La cirugía de descompresión neurovascular se plantea como alternativa al tratamiento médico refractario. Objetivos: Presentar nuestra experiencia respecto a esta patología. Material y métodos: Se realizó una revisión retrospectiva de pacientes operados por HPF refractarios a tratamiento médico en nuestra institución en los últimos 5 años (periodo 2014-2019). Todos fueron intervenidos vía retrosigmoidea. Se evaluaron datos demográficos, evaluación prequirúrgica y evolución postoperatoria. Resultados: Se operaron 4 pacientes bajo técnica microquirúrgica asistido por endoscopía. Edad promedio 52 años (rango 41-61) con una relación femenino masculino 3:1. El 25% (n=1) presentaba paresia facial grado 2 (HB) en el prequirúrgico. No hubo cambios en cuanto al grado de paresia facial en el postoperatorio en ningún caso. Sólo un paciente registró caída leve en la audiometría postquirúrgica. El 75% (n=3) resolvieron el HFP. Conclusión: Si bien nuestra serie es acotada a un número reducido de pacientes, la cirugía descompresiva microvascular es efectiva como alternativa al tratamiento médico refractario del HFP.


Introduction: Primary hemifacial spasm (PHS) is defined as the hyper excitability of the nerve due to the compression of the facial nerve or its nuclei, most commonly by a vascular structure. The surgical indication for microvascular decompression is resistance to pharmacological treatment or severe adverse effects. Objectives: To present our experience in the surgical treatment of this pathology with this novel technique. Materials and methods: We retrospectively reviewed all patients (n=4) with a diagnosis of PHS, who underwent endoscope-assisted microvascular decompression surgery in our institution during the last 5 years. In all the cases, we choose the retrosigmoid approach. We evaluated demographic data, preoperative evaluation, and post-operative evolution. Results: Endoscope-assisted microvascular decompression was the surgical technique in all the patients. The median age was 52 years, the female-male ratio of 3:1. Only one patient presented a grade 2 facial palsy (House-Brackmann scale) in the preoperative evaluation; there were no significant changes in the post-operative evaluation in any patient. Only one patient experienced worsening in the post-operative audiometric follow-up. The 75% (n=3) of the patients solved the HFP after the surgical treatment. Conclusion: By taking into account our experience in this small case series, we can support the concept that endoscope-assisted microvascular decompression is as effective as the open surgical treatment of the PHS.

ABSTRACT

OBJECTIVE@#To explore the effect of anterolateral spinal canal decompression combined with short segment screw fixation with posterior approach for severe thoracolumbar burst fractures with spinal cord injury.@*METHODS@#From January 2016 to June 2018, 16 patients with severe thoracolumbar burst fractures (more than 50% of ratio of spinal canal encroachment, reverse fragment at the posterior edge of the vertebral body) with spinal cord injury were retrospectively analyzed, including 10 males and 6 females, ranging in age from 19 to 57 years old. Causes of injury:8 cases of fall injury, 6 cases of traffic accident injury and 2 cases of other injuries. Fracture site:T@*RESULTS@#All 16 patients were followed up, and the average follow up time was (15.9±5.4) months. The average operation time was (234±41) minutes and the average amount of bleeding was (431±93) ml. The loss of anterior height of injured vertebrae was (52.25±10.10)% before operation, (8.93± 3.61)% at 3 days after operation, and (9.25±2.88)% at the latest follow up. The results of 3 days after operation and the latest follow up were better than that before operation, and there was no significant differencesbetween results at the latest follow up and 3 days after operation (@*CONCLUSION@#For severe thoracolumbar burst fracture and spinal cord injury, with more than 50% of ratio of spinal canal encroachment and reverse fragment at the posterior edge of the vertebral body, the anterolateral spinal canal decompression combined with short segment screw fixation with posterior approach has the characteristics of accurate reduction, complete decompression and firm fixation, and the clinical effect is satisfactory.

ABSTRACT

BACKGROUND: We aimed to confirm the long-term effect of patellar nonresurfacing (patellar decompression) in preventing anterior knee pain after total knee arthroplasty (TKA) and to investigate the possible complications.METHODS: Among patients who underwent primary TKA after being diagnosed as having advanced osteoarthritis (Kellgren-Lawrence grade 4) at our institution from January 2004 to December 2010, 121 patients who were followed up for more than 7 years were included in this study. Patients who underwent TKA with and without patellar decompression were classified as the study group and control group, respectively. A clinical knee rating score was used to compare the postoperative clinical outcomes between groups. To identify complications after patellar decompression, simple radiographs (weight-bearing anteroposterior and lateral views, patella in 30° and 45° axial views, and whole scanogram) were taken during follow-up.RESULTS: There were no complications such as patellar fracture, osteonecrosis, and subluxation. At 2 years after surgery, the prevalence of anterior knee pain was 12.7% and 18.0% in the study group and control group, respectively (p = 0.42), and the number of patients with patellofemoral osteoarthritis grade II or over was lower in the study group (p = 0.03). At 7 years after surgery, the prevalence of anterior knee pain was 18.3% and 24.0% in the study group and control group, respectively (p = 0.45), and there was no statistically significant intergroup difference in the number of patients with patellofemoral osteoarthritis grade II or over (p = 0.11).CONCLUSIONS: Patellar nonresurfacing TKA reduces anterior knee pain in the early postoperative period. The procedure can be considered a relatively safe option with fewer complications; however, its effectiveness appears to decrease over time.
