Absceso del psoas ilíaco secundario a un tumor de colon izquierdo fistulizado al retroperitoneo: caso clínico y análisis de la literatura / Iliopsoas abscess resulting from penetrating left colon cancer to the retroperitoneum: case report and literature review / Abscesso do iliopsoas secundário a tumor de cólon esquerdo fistulizado para o retroperitônio: caso clínico e análise da literatura

Los abscesos del psoas ilíaco secundarios a un tumor de colon fistulizado son excepcionales y potencialmente graves. La mayoría son adenocarcinomas de tipo mucinoso. Su tratamiento es complejo ya que, para lograr una resección oncológica pretendidamente curativa, es necesario realizar una resección ampliada con mayor morbimortalidad. Presentamos el caso de una paciente con un adenocarcinoma mucinoso de colon izquierdo fistulizado al músculo ilíaco y la pared anterolateral del abdomen en la que se realizó una resección multivisceral que incluyó el colon izquierdo, el músculo y la cresta ilíaca y parte de la pared anterolateral del abdomen.

Iliopsoas abscess secondary to perforation of colon cancer is an extremely rare and potentially life-threatening condition. Most tumors are mucinous adenocarcinomas. Its treatment its complex, as most patients need radical extended resections to achieve good oncological results, which are in turn, graved with higher morbidity and mortality. We present the case of a patient with a left colon mucinous adenocarcinoma penetrating to the iliopsoas muscle and the anterolateral abdominal wall that required a multivisceral resection including left colon, iliac muscle and crest and part of the anterolateral abdominal wall.

Abscessos do iliopsoas secundários a um tumor de cólon fistulizado são raros e potencialmente graves. A maioria são adenocarcinomas do tipo mucinoso. Seu tratamento é complexo, pois, para se obter uma ressecção oncológica supostamente curativa, é necessário realizar uma ressecção ampliada com maior morbimortalidade.

Sacroileítis infecciosa secundaria a un absceso del iliopsoas ­ reporte de un caso / Infectious sacroiliitis secondary to an iliopsoas abscess ­ a case report

La sacroileítis infecciosa (SII), también descrita en la literatura como sacroileítis séptica o piógena, es una patología infrecuente, y su diagnóstico constituye un reto debido a su rareza relativa y la diversa presentación clínica, que frecuentemente imita otros trastornos más prevalentes originados en estructuras vecinas. Se requiere un alto índice de sospecha y un examen físico acucioso para un diagnóstico oportuno, mientras que los estudios de laboratorio y de imagen ayudan a confirmar el diagnóstico y dirigir la estrategia de tratamiento apropiada para evitar complicaciones y secuelas a corto y mediano plazos. Presentamos un caso de paciente de género femenino de 36 años, con cuadro clínico de SII izquierda, secundaria a un absceso del músculo iliopsoas, condición que generalmente se presenta como una complicación de la infección. Se realizaron los diagnósticos clínico, imagenológico y Biológico, se inició el tratamiento antibiótico oportuno, y se logró una excelente evolución clínica, sin secuelas

Infectious sacroiliitis (ISI), also described in the literature as septic or pyogenic sacroiliitis, is an infrequent pathology, and its diagnosis constitutes a challenge due to its relative rarity and the diverse clinical presentation, frequently imitating other more prevalent disorders originating in neighboring structures. A high index of suspicion and a thorough physical examination are required in order to establish an opportune diagnosis, while laboratory and imaging studies help confirm the diagnosis and direct the appropriate treatment strategy to avoid complications and sequelae in the short and medium terms. We herein present a case of a female patient aged 36 years, with a clinical picture of left ISI, secondary to an iliopsoas muscle abscess, a condition that usually presents as a complication of the infection. The clinical, imaging and microbiological diagnoses were made, the timely antibiotic treatment was initiated, and an excellent clinical evolution without sequelae was achieved.

Absceso del psoas ilíaco: importancia del tratamiento percutáneo en una serie consecutiva de casos / Psoas abscess: importance of percutaneous drainage in a consecutive case series

Antecedentes: el absceso del psoas ilíaco es una entidad poco frecuente y de etiología variable. Su ubicación y cuadro clínico inespecífico la convierte en una entidad de difícil diagnóstico para el cirujano general. La oportunidad de tratar una serie de casos en un período de tiempo relativamente corto para este tipo de patología motivan esta comunicación. Objetivo: a partir de una serie consecutiva de casos, analizar etiología, clínica, y enfoque diagnóstico terapéutico, con especial énfasis en el drenaje percutáneo , como así también una sucinta revisión de la bibliografía reciente. Material y métodos: estudio observacional retrospectivo de una serie consecutiva de casos Resultados: la serie consta de 6 casos, 5 de tipo primario y 1 de tipo secundario. La signos más frecuentes fueron el dolor, la impotencia funcional y la leucocitosis. La Tomografía axial computada de abdomen con y sin contraste fue el método diagnóstico de elección. El drenaje percutáneo fue el tratamiento de elección en 5 casos (83,3%) mientras que en el restante se optó por antibioticoterapia y el drenaje de una colección adyacente. La evolución de todos los casos fue favorable. Conclusión: el absceso de psoas ilíaco es una patología que necesita un alto nivel de sospecha dada su clínica inespecífica. Para su diagnóstico, junto acon la clínica la Tomografía es el método de elección. El drenaje percutáneo de las colecciones bajo control tomográfico es un opción segura y eficaz para el tratamiento de esta entidad.

Background: The of the iliopsoas abscess is a rare entity with a variable etiology. Its location and nonspecific clinical features makes it becomes a diagnostic and therapeutic challenge for the general surgeon. The opportunity to treat a series of cases in a relatively short period of time motivates this communication. Objective: From a consecutive case series, we analyze etiology, clinical features , as well as diagnostic and therapeutic approaches, with special emphasis on percutaneous drainage, as well as a brief review of recent literature. Material and methods: Retrospective analysis of a consecutive series of six patients diagnosed with an ilipsoas abscess in a tertiary care center. Results: The series consists of 6 cases, 5 of primary type and 1 of secondary type. Pain, Limp and leucocitosis were the more prevalent signs; computed tomography of the abdomen was the diagnostic method of choice. Percutaneous drainage was the therapeutic option in 5 cases (83.3%), while in the remaining, antibiotic therapy and the drainage of an adjacent collection were indicated. The evolution of all cases was favorable with no mortality nor morbidity. Conclusion: The iliac psoas abscess is a pathology that needs a high level of suspicion given its nonspecific presentation. For diagnosis, together with the clinic, computed tomography is the method of choice. Percutaneous drainage of collection under tomographic control is a safe and effective option for the treatment of this entity.

Unusual abscess masquerading as poorly differentiated adenocarcinoma of the colon showing characteristics of choriocarcinoma

Extragonadal non-gestational choriocarcinoma (ENC) is an uncommon malignant tumor occasionally found in the gastrointestinal tract. ENC is characterized by a biphasic tumor growth with distinct areas of adenocarcinoma and choriocarcinoma differentiation. Primary choriocarcinoma of the colon is extremely rare, with only 21 cases reported in the literature. Most of the perforation of colorectal cancers occurs in the abdominal cavity, while abdominal wall abscess is rare; the psoas abscess associated with colon carcinoma is even less observed. Herein, we report the case of a 61-year-old female with poorly differentiated adenocarcinoma of the ascending colon and sigmoid, with choriocarcinomatous differentiation, masquerading a psoas abscess formation. Unfortunately, despite the aggressive therapy, the patient's disease rapidly progressed, and she died within 2 months after the diagnosis. The typical morphological pattern, immunohistochemistry, and its correlation with serum β-human chorionic gonadotropin enabled a correct diagnosis.

Successful medical drainage and surgical treatment for vertebral osteomyelitis and bilateral psoas abscess with gas formation caused by klebsiella pneumoniae in a diabetic patient

SUMMARY OBJECTIVE: We describe the case of a diabetic patient who developed vertebral osteomyelitis and bilateral psoas abscess with gas formation due to klebsiella pneumoniae. METHODS: A 64-year-old woman with a 4-year history of type-2 diabetes mellitus was admitted to the Emergency Department. The subject had a 2-day history of high-grade fever associated with chills and a 5-hour history of consciousness. She received empirical treatment with febrifuge, after which her fever decreased. RESULTS: Her fever recurred after an interval of three hours. A computed tomography scan of the abdomen revealed vertebral osteomyelitis and bilateral psoas muscle abscess with gas formation. Blood culture and purulent fluid described the growth of the Klebsiella pneumoniae. The patient received antibiotic therapy and bilateral drainage therapy after the drainage catheter was placed into the abscess cavity by CT-guidance. Due to the serious damage to the vertebral column and permanent pain, the patient underwent minimally invasive internal spinal fixation and recovered successfully. CONCLUSION: A case of vertebral osteomyelitis and bilateral psoas abscess with gas formation caused by Klebsiella pneumoniae in a diabetic patient. Antibiotic therapy, drainage, and minimally invasive internal spinal fixation were performed, which enabled a good outcome.

RESUMO OBJETIVO: Descrever o caso de uma paciente diabética que desenvolveu osteomielite vertebral e abcesso bilateral do psoas com formação de gás causada por klebsiella pneumoniae. MÉTODOS: Uma mulher de 64 anos de idade, com 4 anos de histórico de diabetes mellitus tipo 2, foi admitida no Serviço de Emergência. A paciente apresentava um quadro de dias de febre alta acompanhada de calafrios e um histórico de 5 horas de consciência. Ela recebeu tratamento empírico com antitérmico, após o qual a febre diminuiu. RESULTADOS: A febre retornou após um intervalo de três horas. Uma tomografia computadorizada do abdome revelou osteomielite vertebral e abcesso bilateral do músculo psoas com formação de gás. A cultura do sangue e o fluido purulento revelaram o crescimento de Klebsiella pneumoniae. A paciente recebeu antibióticos e terapia de drenagem bilateral após o cateter de drenagem ser posicionado na cavidade do abscesso com auxílio de TC. Devido a sérios danos à coluna vertebral e a dor permanente, a paciente foi submetida à fixação vertebral interna minimamente invasiva e recuperou-se com sucesso. CONCLUSÃO: Um caso de osteomielite vertebral e abscesso do psoas bilateral com a formação de gás causada por Klebsiella pneumoniae em uma paciente diabética. Antibioticoterapia, drenagem e fixação vertebral interna minimamente invasiva foram realizadas, o que permitiu um bom resultado.

Absceso de psoas iliaco: un desafío diagnóstico / Psoas-Iliac Abscess a dignotic challengen

El absceso de músculo psoas iliaco se considera una rare-za. Su detección ha mejorado con la utilización de imágenes como la tomografía computada o la resonancia magnética. Presentamos una revisión de casos de absceso de psoas-iliaco internados entre julio de 2015 y febrero de 2018 en un hospital de CABA, Argentina.En este periodo se diagnosticaron un paciente conside-rado de origen primario y ocho de origen secundario. Se observó predominio de colecciones asociadas a es-pondilodiscitis. El síntoma más frecuente fue la fiebre. Staphylococcus aureus fue el germen más rescatado en muestras microbiológicas. Se debe tener alto índice de sospecha de esta patología ante la presencia de fiebre, dolor lumbar y en ocasiones alteración de la marcha. El empleo de antibióticos de amplio espectro sumado a la evacuación de colecciones constituyen la estrategia más efectiva

Psoas-iliac muscle abscess is considered a rarity, the use of images such as computed tomography or magnetic reso-nance imaging has improved its detection.This study reviews cases of psoas-iliac abscess in hospi-talized patients between July 2015 and February 2018 in a hospital in CABA, Argentina.In one of the patients the origin was considered primary ,while in the other eight it was secondary. There was a pre-dominance of collections associated with spondylodiscitis. The most frequent symptom was fever. Staphylococcus au-reus was the most frequent organism obtained in microbio-logical samples. A high level of suspicion must be held in the presence of fever, lumbar pain and sometimes alteration of the gait. The use of broad spectrum antibiotics in addition to evacuation of collections is the most effective strategy.

Tratamiento percutáneo del absceso del psoas / Percutaneous drainage of psoas muscle abscess

This article details the treatment of lymphangioma of the face with intralesional bleomycin: with a case report and literature review. Surgical treatment of lymphangioma of the face is a difficult task to achieve, due to close vicinity of the lesion to the facial nerve and possibility of scar tissue formation. Inefficient surgical removals generally will give rise to high recurrence rates because of infiltrative and diffuse extension of the lesion. However, complete cure has been described by non-surgical methods with intralesional bleomycin injection under ultrasonographic guidance. Lymphangioma is a rare congenital malformation of the lymphatic system, frequently seen in the head and neck. Percutaneous sclerotherapy of lymphangioma involves the injection of sclerosing substances into the lymphangioma. This study aims to evaluate the effectiveness of intralesional bleomycin sclerotherapy in the treatment of lymphangioma, and to determine the incidence of complications in the treatment. Intralesional bleomycin therapy was very effective in the treatment of lymphangioma. Bleomycin administered as intralesional injection was found to be safe as there was no lesions complicating or side effects observed in the study.

Percutaneous drainage of iliopsoas abscess: an effective option in cases not suitable for surgery / Drenagem percutânea de abscesso de iliopsoas: uma opção efetiva em casos não candidatos à cirurgia

ABSTRACT The aim of this study were to describe the technique of percutaneous drainage of iliopsoas abscess, and to discuss the benefits of using this minimally-invasive tool. A single center study with retrospective analysis of patients with psoas abscess confirmed by imaging scans, sent to the interventional medicine center and submitted to computed tomography and ultrasound-guided percutaneous drainage, from November 2013 to August 2016. Seven patients underwent percutaneous drainage of psoas abscess in this period. The mean initial drained volume was 61.4±50.7mL (ranging from 10 to 130mL), and the mean drainage duration was 8.3±2.8 days (ranging from 4 to 12 days). The success rate of the percutaneous procedures was 71.5%, and two patients required re-intervention. Image-guided percutaneous drainage of iliopsoas abscess is a minimally invasive, efficient and safe procedure, and an extremely valuable technique, especially for patients who are not suitable for surgical repair.

RESUMO Os objetivos deste estudo foram descrever a técnica de drenagem percutânea de abscesso de iliopsoas e discutir os benefícios do uso desta ferramenta minimamente invasiva. Trata-se de estudo unicêntrico com análise retrospectiva de pacientes com abscesso de psoas confirmado por exames de imagem, encaminhados a um centro de medicina intervencionista e submetidos à drenagem percutânea guiada por tomografia computadorizada e ultrassonografia, de novembro de 2013 a agosto de 2016.

Absceso de psoas / Psoas abscess

El absceso de psoas es una enfermedad relativamente rara. Muchos casos presentan características clínicas atípicas. El absceso de psoas puede ser primario en pacientes inmunodeprimidos o secundario a infecciones gastrointestinales y genitourinarias. En los países no desarrollados, la mayoría de estos pueden ser de etiología tuberculosa. Una alta sospecha clínica, una buena historia clínica y estudios de imagen, pueden ser útiles en el diagnóstico y tratamiento de la enfermedad. El tratamiento temprano con antibióticos, drenaje guiado o cirugía abierta es necesario debido a su alta morbimortalidad. Se reporta el caso de un paciente varón de 57 años con historia de Diabetes mellitus (DM) de 20 años de evolución, quien refiere dolor en región lumbar izquierda asociada a aumento de volumen y fiebre intermitente, por lo que se hospitaliza, detectándose un absceso de psoas izquierdo, el cual es drenado por cirugía abierta con abordaje extra-peritoneal, presentando evolución favorable.

Psoas abscess is a relatively rare disease. Many cases present atypical clinical features. Psoas abscess may be primary in immunosuppressed patients or secondary to gastrointestinal and genitourinary infections. In non-developed countries most of these can be of tuberculous etiology. A high clinical suspicion, a good clinical history and imaging studies can be useful in diagnosing the disease. Early treatment with antibiotics, guided drainage or open surgery is necessary due to its high morbidity and mortality. It's reported the case of a male patient of 57 years with a history of diabetes mellitus (DM) of 20 years of evolution, who referred pain in the left lumbar region associated with increased volume and intermittent fever, so he is hospitalized, detecting an extensive left psoas abscess which is drained by open surgery with extraperitoneal approach, showing favorable evolution.

Feasibility study of preoperative percutaneous catheter drainage in the treatment of lumbar tuberculosis with psoas abscess / 中国骨伤

OBJECTIVE@#To investigate the effect of preoperative percutaneous drainage in lumbar tuberculosis with psoas abscess, through compare the clinical efficacy of two different methods.@*METHODS@#Thirty-six patients with lumbar tuberculosis complicated with psoas abscess in corresponding with the inclusion criteria were admitted in Zhejiang Province Traditional Chinese Medicine Hospital from January 2015 to January 2017. The patients were divided into group A and group B according to the different therapeutic methods. All patients were given the standard anti tuberculosis treatment, and percutaneous catheter drainage was used in group A after admission immediately for psoas abscess before operation, while group B with no special treatment. At 3 weeks after anti tuberculosis treatment, 2 patients were excluded in group B, which had to postpone operation because of no reduction in erythrocyte sedimentation rate(ESR) and C reactive protein(CRP). Finally 34 patients were enrolled in this study. There were 18 cases in group A, including 10 males and 8 females, aged from 24 to 73 years old with an average of(42.5±10.2) years. There were 16 cases in group B, including 9 males and 7 females, aged from 23 to 75 years old with an average of(42.3±9.8) years. All patients were treated with posterior pedicle screw fixation, anterior debridement and bone graft fusion. Anterior surgery bleeding volume, operation time, anterior incision length, postoperative anus exhaust time, VAS score, Cobb angle, ESR, CRP changes and postoperative sinus formation were compared between two groups.@*RESULTS@#All patients were followed up for 6 to 21 months with an average of 13 months. At the last follow-up, no mixed infection, tuberculosis recurrence, pedicle screw loosening and nail withdrawal were found. The average operative time, anterior surgery bleeding volume and anterior incision length of group A were less than that of group B(0.05). There was 1 case sinus formation in group A and 5 cases in group B, there was significant difference in sinus formation rate between two groups (0.05). Spinal cord nerve injury was obvious improved after operation, but there was no significant difference between two groups.@*CONCLUSIONS@#Preoperative percutaneous catheter drainage is a safe and feasible method for the treatment of lumbar tuberculosis with psoas abscess. It can increase the effect of anti tuberculosis before operation, reduce the surgical trauma and reduce the incidence of postoperative complications. It can be recommended in clinical application.

Cerebrospinal fluid infection after lumbar nerve root steroid injection: a case report / 대한마취과학회지

A 45-year-old woman was admitted due to severe headache and neck stiffness. She had visited a local clinic for back pain and received a lumbar nerve root steroid injection 10 days before admission. Computed tomography and magnetic resonance imaging showed psoas abscess, pneumocephalus, and subdural hygroma. She was diagnosed with psoas abscess and meningitis. The abscess and external ventricle were drained, and antibiotics were administered. Unfortunately, the patient died on hospital day 19 due to diffuse leptomeningitis. Lumbar nerve root steroid injections are commonly used to control back pain. Vigilance to "red flag signs" and a rapid diagnosis can prevent lethal outcomes produced by rare and unexpected complications related to infection. Here, we report a case of fatal meningitis after infection of the cerebrospinal fluid following a lumbar nerve root steroid injection.

Absceso del psoas y osteomielitis de la columna lumbar: Caso clínico / Psoas abscess and lumbar spine osteomyelitis: Case report

El absceso del psoas es una enfermedad infrecuente en niños. Puede tener una presentación clínica inespecífica, ser de inicio insidioso y relacionarse o no con fiebre. El tipo más frecuente en pediatría es primario; sin embargo, en ocasiones, puede ser de origen secundario y asociarse a infecciones graves, como la osteomielitis, por lo que se requiere un alto índice de sospecha para detectarlo y tratarlo oportunamente. Presentamos un caso atípico de absceso del psoas con infiltración del cuerpo vertebral de L2 en un paciente masculino de 14 años previamente sano, sin antecedente de traumatismo ni fiebre al momento del ingreso. Se realizaron una radiografía y una ecografía, pero el diagnóstico se confirmó a través de una resonancia nuclear magnética de columna lumbosacra. Conhemocultivos positivos para Staphylococcus aureus meticilino resistente, completó 2 semanas de tratamiento antibiótico endovenoso y 4 semanas por vía oral con negativización de cultivos y resolvió por completo la sintomatología inicial.

Psoas abscess is a common disease in children. It can have a nonspecific clinical presentation, insidious onset and sometimes fever. The most common type in children is the primary one; however, it can sometimes be of secondary origin and associated with severe infections such as osteomyelitis so a high index of suspicion is required to detect and treat it promptly. We present an unusual case of psoas abscess with infiltration of the vertebral body of L2 in a 14 year old male patient previously healthy with no history of trauma or fever on admission. X-ray and ultrasound were performed but the diagnosis was confirmed by magnetic resonance imaging of the lumbosacral spine. With positive blood cultures for methicillin-resistant Staphylococcus aureus he completed 2 weeks of intravenous antibiotic therapy and 4 weeks of oral antibiotic therapy with blood cultures negativization and resolution of symptoms.

Absceso del psoas como presentación de tuberculosis vertebral: reporte de un caso / Psoas abscess as spinal tuberculosis presentation: case report

Introducción: El absceso del psoas es un cuadro infrecuente cuyo principal agente etiológico es el Staphyloccocus aureus, y que con baja frecuencia puede ser de etiología tuberculosa como complicación de una afección vertebral por Mycobacterium tuberculosis. Presentación del caso: Mujer de 58 años, mapuche, con antecedentes de enfermedad pulmonar obstructiva crónica y alcoholismo crónico, consultó por cuadro de dos meses de evolución de dolor lumbar, baja de peso y paresia de extremidad inferior derecha que impedía la marcha. Tomografía computada (TC) de columna evidenció espondilodiscitis y absceso del psoas derecho, iniciándose tratamiento antibiótico cubriendo Staphyloccocus aureus. Los hemocultivos y los cultivos de la colección resultaron negativos por lo que se decidió mantener tratamiento ambulatorio. Paciente consultó cuatro meses después por exacerbación de su disnea basal de dos semanas de evolución, radiografía de tórax y TC de tórax de alta resolución compatibles con tuberculosis pulmonar con diseminación miliar bilateral, por lo cual, se inició tratamiento antituberculoso, realizándose baciloscopías que resultaron negativas. Además, se solicitó identificación del bacilo de Koch mediante reacción de polimerasa en cadena que resultó positiva, con lo que se confirmó el diagnóstico de tuberculosis miliar y mal de Pott. Se decidió reevaluar con TC de columna una vez finalizado el tratamiento antituberculoso para decidir conducta quirúrgica. Discusión: Es importante la sospecha activa de etiología tuberculosa ante una espondilodiscitis y un absceso del psoas, pese a su baja frecuencia. El inicio del tratamiento en forma precoz puede modificar la progresión de una infección que puede ser invalidante e incluso mortal.

Introduction: The Psoas abscess is an infrecuent condition which main ethiology is the Staphyloccocus aureus and with less frequency can be a vertebral tuberculosis complication caused by Mycobacterium tuberculosis. Case Report: a 58 years old female, Mapuche, with Chronic Obstructive Pulmonar Disease and chronic alcoholism antecedents, was admitted in the emergency room with a two month old lumbar pain, loss of weight and right inferior extremity paresia which didn't allowed her to walk. The column's Computed Tomography (CT) showed spondylodiscitis and a right psoas abscess, the antibiotherapy, covering Staphyloccocus aureus, was started. The hemoculives and abscess' cultives were negative, so it was decided to continue with ambulatory treatment. The patient was admitted four month later because of two weeks of exacerbation of her basal dysnea. The thorax Radiography and high resolution CT were compatibles with pulmonary tuberculosis with bilateral miliar disemination. Antituberculosis treatment was started, bacilloscopies were negative, also, a Polymerase Chain Reaction identification of Koch's bacillus was performed, resulting positive, confirming the diagnosis of miliar tuberculosis and Pott's disease. Once antituberculosis treatment was finished, a new column's CT was requested to decided surgical conduct. Discussion: Is important to actively suspect of tuberculosis ethiology in presence of spondylodiscitis and psoas abscess, despite it's low frequency. The early treatment start may modify the progresion of an infección that can be invalidating and even mortal.

Case-control studies of two kinds of method for the treatment of lumbar tuberculosis with psoas abscess / 中国骨伤

<p><b>OBJECTIVE</b>To compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.</p><p><b>METHODS</b>From January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.</p><p><b>RESULTS</b>The loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).</p><p><b>CONCLUSION</b>Lumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.</p>

Non-Caseating Granulomatous Infective Spondylitis: Melioidotic Spondylitis

STUDY DESIGN: Retrospective clinical analysis. PURPOSE: To delineate the clinical presentation of melioidosis in the spine and to create awareness among healthcare professionals, particularly spine surgeons, regarding the diagnosis and treatment of melioidotic spondylitis. OVERVIEW OF LITERATURE: Melioidosis is an emerging disease, particularly in developing countries, associated with a high mortality rate. Its causative pathogen, Burkholderia pseudomallei, has been labeled as a bio-terrorism agent. METHODS: We performed a retrospective analysis of patients who were culture positive for B. pseudomallei. Assessment of patients was performed using clinical, radiological, and blood parameters. Clinical measures included pain, neurological deficit, and return to work. Radiological measures included plain radiography of the spine and magnetic resonance imaging. Blood tests included erythrocyte sedimentation rate and C-reactive protein levels. RESULTS: Four patients having melioidosis with spondylitis were evaluated. All of them had diabetes mellitus; three had multiple abscesses which required incision and drainage. Their clinical spectrum was similar to that of tuberculous spondylitis; all had back pain and radiology revealed infective spondylodiscitis with prevertebral and paravertebral collections with psoas abscess. Three patients underwent ultrasound-guided drainage of the psoas abscess and one had aspiration of the subcutaneous abscess. Bacteriological cultures showed presence of B. pseudomallei, and histopathology showed non-caseating granulomatous inflammation. All patients were treated with intravenous Ceftazidime for 2 weeks, followed by oral bactrim double strength and Doxycycline for 20 weeks. All patients improved with treatment and were healed at follow up. CONCLUSIONS: Melioidosis presents with a clinical spectrum similar to that of tuberculosis. A diagnosis of melioidotic spondylitis should be considered, particularly in patients with diabetes with neutrophilic leukocytosis and clinical-radiological features suggestive of infective spondylodiscitis. Bacteriological culture and histopathology helps in differentiating the two conditions. Health education for healthcare professionals is important for correctly diagnosing this disease.
