Conservative management for pediatric craniocervical Pott's disease: A case study and literature review.

Craniocervical Pott's disease is rare, particularly in the pediatric population. The importance of motion preservation in this age group renders managing this disease even more challenging. The literature regarding craniocervical Pott's disease comes from endemic regions. Most authors will agree on early surgical intervention in cases of neurological compromise or severe instability, while patients with minimal symptoms will do well with conservative management. Controversy remains when patients are mildly symptomatic but with imaging findings concerning for significant instability. Here, we present the case of a 15-year-old male presenting with craniocervical tuberculoma with radiographic instability and advanced bony destruction without overt neurological deficits. He was managed with a rigid cervical collar and completed 1 year of anti-tuberculosis therapy. At 1-year follow-up, he had an intact range of motion, was pain-free, and remained neurologically intact. Although this case suggests good outcomes with conservative management are possible, more long-term follow-up is required to assess the need for delayed surgical intervention in this unique population.

Study on the expression level of NF-κB and clinical evaluations in spinal tuberculosis patients.

Spinal tuberculosis or tuberculous spondylitis is one of the most common types of skeletal tuberculosis. Complications of the spine and spinal cord tuberculosis include destruction of the vertebrae, deformity, and paraplegia. Since in some patients, the clinical manifestations of tuberculosis are unusual and timely diagnosis and treatment of this disease can prevent its serious consequences, so in the present study, some cases of rare manifestations of tuberculosis were investigated. The expression of the NF-κB gene in these patients was also evaluated. In this regard, 36 patients with spinal tuberculosis and 30 healthy individuals (as a control group) were assessed. Clinical symptoms, imaging, laboratory tests, pathology, and response to treatment related to patients with spinal tuberculosis and spinal cord tuberculosis were evaluated. NF-κB expression was also evaluated using the PCR technique in peripheral white blood cell samples. The obtained results were analyzed using SPSS ver. 16, χ2 and T-test statistical methods. Mann-Whitney U test and Kruskal-Wallis non-parametric tests were used to analyze non-parametric data. The results showed that out of 36 cases of spinal tuberculosis, 29 cases had spinal tuberculosis, five cases had tuberculous radiculomyelitis, one case had spinal intramedullary tuberculoma, and one case had syringomyelia. 52.78% of patients were male, and 70% of cases were observed between the ages of 35 and 55 years. Fever and back pain were seen in more than 80% of cases. The study of NF-κB expression in the control and case groups showed that the NF-κB expression in the case group increased compared to the control group. This increase was statistically significant (P = 0.0071). In general, in the present study, the methods of clinical diagnosis of spinal tuberculosis were evaluated. Also, the amount of NF-κB transcription factor was evaluated as an effective genetic factor in the diagnosis of this disease.

Clinical Conundrum: A Complex Case of Pott Disease in Pregnancy.

Spinal tuberculosis (TB) is a rare form of extrapulmonary TB that can be clinically difficult to diagnose, particularly in pregnancy. This 24-year-old G2, P0 patient was diagnosed at 19 weeks gestation, 2 days after a protracted admission for hyperemesis gravidarum, COVID-19 infection, and unexplained transaminitis with bilateral lower limb weakness and urinary retention. She underwent emergent spinal decompression surgery with expectant management on intravenous antitubercular medication and cesarean delivery at 343 weeks gestation. Spinal tuberculosis is a difficult diagnosis, impacted by medical comorbidities, pregnancy, and diagnostic bias. This case describes successful antenatal management of spinal tuberculosis and highlights the importance of interdisciplinary care.

MRI findings in Pott's spine and correlating clinical progress with radiological findings.

PURPOSE: To document magnetic resonance imaging (MRI) changes in Pott's spine and to correlate these with clinical findings and outcome. METHODS: Patients with Pott's spine having more than one set of MRI were included in the study. Patients were grouped according to timing of their second MRI. The MRI findings included changes in bone, disc, spinal cord, and soft tissue. The MRI changes were categorized into improvement, no change, or worsening. "Paradoxical worsening" was defined as radiological worsening in setting of clinical improvement, as described by improvement of Nurick's grade. Outcome was defined by mRS scale at three, six, and 12 months. The MRI findings and outcome were correlated. RESULTS: The results are based on 36 patients. The MRI changes included vertebral changes in form of spondylodiscitis in 33 (92%), epidural abscess in 29 (81%), spinal cord changes including edema and granuloma in 17 (47%), paravertebral abscess in 29 (81%), and vertebral body collapse in 12 (33.3%) patients. At three months, clinical improvement occurred in eight out of 12 patients, deterioration in two, and no change in two. Spinal MRI revealed improvement in one patient only; whereas eight had deterioration and three had no change. At six months, all nine patients improved clinically, but MRI showed improvement in only four, while another four showed deterioration and one had no change. In the nine and 12 months group, while all patients clinically improved, MRI showed minimal worsening. CONCLUSION: In Pott's spine, the clinical improvement precedes the radiological improvement.

Clinical efficacy of three types of autogenous bone grafts in treatment of single-segment thoracic tuberculosis: A retrospective cohort study.

A retrospective study investigated and compared the results of lamina with spinous process (LSP), transverse process strut (TPS) and iliac graft (IG) as bone graft in thoracic single-segment spinal tuberculosis(TB) with the one-stage posterior approach of debridement, fusion and internal instrumentation. 99 patients treated from January 2012 to December 2015 were reviewed. LSP was performed in 35 patients (group A), TPS was undertaken in 33 patients (group B), and IG was carried out in 31 patients (group C). Surgical time, blood loss, hospitalization time, drainage volume, and follow-up (FU) duration were recorded. The visual analog scale (VAS), Oswestry Disability Index (ODI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), American Spinal Injury Association (ASIA) grade, segmental angle, intervertebral height and bone fusion time were compared between preoperative and final FU. All the patients were followed up for a mean 43.90±10.39 months in group A, 45.30±6.20 months in group B, 44.32±7.17 months in group C without difference(P>0.05). The mean age was younger, the blood loss was less, the hospitalization time and the surgical time were shorter in group A than those in group B and C (P<0.05). The drainage volume was less in group A than that in group B and group C. The CRP, ESR, VAS, and ODI were significantly decreased and there were no significant difference among the groups at the final FU. The neurological function after surgery was improved compared with preoperation among the groups. The bony fusion at a mean time 12.90±3.91 months in group A was longer than that in group B (6.75±1.55 months) and group C (5.52±1.64 months) (P<0.05). No significant difference was found at the mean segmental angle, mean intervetebral height of preoperation and final FU among the groups (P>0.05). In conclusion, the LSP and TPS as bone graft are reliable, safe, and effective for single-segment stability reconstruction for surgical management of thoracic TB and TPS could be new bone graft methods.

Minimally invasive surgery for paravertebral or psoas abscess with spinal tuberculosis - a long-term retrospective study of 106 cases.

BACKGROUND: Minimally invasive surgery (MIS) is a common treatment option for paravertebral or psoas abscesses (PAs) in patients with spinal tuberculosis (ST). However, its efficacy remains controversial. The aim of the study was to evaluate the efficacy of MIS for PA with ST combined with anti-tuberculous chemotherapy. METHODS: A total of 106 consecutive patients who underwent MIS for ST with PA from January 2002 to Oct 2012 were reviewed. The MIS involved computed tomography (CT)-guided percutaneous catheter drainage and percutaneous catheter infusion chemotherapy. Clinical outcomes were evaluated based on the changes observed on preoperative and postoperative physical examination, inflammatory marker testing, and magnetic resonance imaging (MRI). RESULTS: The mean follow-up period was 7.21 ± 3.15 years. All surgeries were successfully completed under CT-guidance without intraoperative complications and all patients experienced immediate relief of their symptoms, which included fever and back pain. The preoperatively elevated erythrocyte sedimentation rate and C-reactive protein values returned to normal at a mean period of 3 months postoperatively. Solid bony union was observed in 106 patients and no abscesses were found on MRI examination. CONCLUSION: MIS carries advantages in terms of less invasiveness, precise drainage, and enhanced local drug concentration. While the technique has not been fully characterized and clinically prove, its use in addition to conservative chemotherapy and open debridement and instrumental fixation may be recommended for patients with ST and PA.

Management of Craniovertebral Junction Tuberculosis Presenting with Atlantoaxial Dislocation.

Tuberculosis (TB) rarely involves the craniovertebral junction (CVJ). Atlantoaxial dislocation (AAD) is one of the most commonly encountered lesions in craniocervical TB. The incidence of TB and its craniovertebral manifestation is increasing even in developed countries because of intercontinental migration and increased prevalence rates of immunosuppression conditions. While the treatment of craniovertebral TB is well standardized and relies on conservative measures, the treatment of TB with AAD is disputable. In this paper we present a review of the literature and elucidate our approach to craniovertebral TB with AAD through a case illustration.

Comparison of three surgical approaches for thoracolumbar junction (T12-L1) tuberculosis: a multicentre, retrospective study.

BACKGROUND: The surgical approaches to thoracolumbar junction (T12-L1) tuberculosis were controversial. We aimed to compare the safety and efficacy of three different procedures through a multicentre retrospective study. METHODS: The medical records of thoracolumbar junction tuberculosis patients (n = 177) from January 2005 to January 2015 were collected and reviewed. Forty-five patients underwent anterior debridement and instrumented fusion (Group A), 52 underwent anterior combined with posterior debridement and instrumented fusion (Group B) and 80 underwent posterior-only debridement and instrumented fusion (Group C). Patients with neurological deficit were 10 in Group A, 23 in Group B, 36 in Group C. All patients had a standard preoperative and postoperative anti - tuberculous therapy regimen. Clinical outcomes, laboratory indexes and radiological evaluation of the three groups were compared. Operations at each centre were performed by the respective senior medical teams of the six different hospitals. RESULTS: All three surgical approaches achieved bone fusion and pain relief. Cases with neurological deficits had different degrees of improvement after surgery. The operative time was 330.2 ± 45.4 min, 408.0 ± 54.3 min, 227.9 ± 58.5 min, and the blood loss was 744.0 ± 193.8 ml, 1134.6 ± 328.2 ml, 349.8 ± 289.4 ml in groups A, B and C respectively. The average loss of correction was 5.5 ± 3.7° in group A, 1.6 ± 1.9° in group B, 1.7 ± 2.2° in group C, and the difference between groups except B vs C were of statistically significant (P < 0.05). CONCLUSIONS: For patients with thoracolumbar junction (T12-L1) tuberculosis, the posterior-only procedure is the better than the anterior-only procedure in the correction of kyphosis and maintenance of spinal stability. The posterior-only procedure is recommended because it achieves the same efficacy as combined procedure with shorter operation time, less blood loss and trauma.

Evaluation of clinical outcomes of one-stage anterior and posterior surgical treatment for atlantoaxial tuberculosis complicated with neurological damage.

BACKGROUND: Surgical treatment is mainly used for atlantoaxial tuberculosis with neurological damage. However, the anatomic structure around the atlantoaxial joint is complex, and the position of vertebral body is deep, which increases the difficulty of the operation and it is challenging for the surgeon to develop surgical strategy. The purpose of this study was to evaluate the clinical outcomes of one-stage combined anterior and posterior surgical treatment approach for atlantoaxial tuberculosis with neurological impairment. METHODS: From January 2005 to January 2015, 12 patients suffering from atlantoaxial tuberculosis with neurological impairment were surgically treated by one-stage combined anterior and posterior approach. Preoperative CT scanning and MRI imaging showed unilateral or bilateral lateral mass destruction of the atlas, and varying destruction degrees of odontoid process, loss of atlantoaxial stability, and tuberculosis focus into the spinal canal resulting in the corresponding spinal cord compression in all patients. The preoperative neurological classifications were Class C for 4 cases, D for 8 cases according to the American Spinal Injury Association (ASIA) system. Quadruple sensitive anti-TB drug treatment was used in all 12 patients preoperative and postoperative. Patients' clinical symptoms and neurological function recovery were evaluated by comparing the Visual Analogue Scale (VAS) score, Neck Disability Index (NDI), Japanese Orthopedic Association (JOA) score and ASIA grading before operation and at the final follow-up. RESULTS: Mean surgical duration was 263.3 ± 43.6 min. Intraoperative blood loss was averagely 529.2 ± 169.8 ml. The average fusion period was 7.3 ± 1.5 months. No instrumentation loosening, migration or breakage was observed during the follow-up of 6.5 ± 2.9 years. The VAS, NDI and JOA scores were significantly changed to 1.00 ± 0.95, 9.50 ± 3.34 and 15.42 ± 1.44 at last follow-up (P < 0.05). The neurological function of all 12 patients was recovered to Class E according to the ASIA grading system. CONCLUSION: In the treatment of atlantoaxial tuberculosis with neurological impairment, one-stage combined anterior and posterior surgical approach have the ability to complete debridement and decompression, and reconstruction of the stability of the upper cervical spine.

Anterior versus posterior instrumentation for treatment of thoracolumbar tuberculosis : A meta-analysis.

BACKGROUND: To compare clinical and functional outcomes of anterior versus posterior debridement and spinal fixation for surgical treatment of thoracolumbar tuberculosis. METHODS: A computer-based online search of the Cochrane Library, PubMed, EMBase, Wanfang, VIP, and the CNKI database was performed. The methodological quality of included studies was evaluated, and data analyses were performed using RevMan 5.0 software (The Nordic Cochrane Centre, The Cochrane Collaboration Copenhagen, Denmark). RESULTS: Eleven trials were studied, with eight performed in China, two in Egypt, and one in India. The results showed significant differences between the two operative approaches in terms of correction of kyphotic angle and intraoperative blood loss, but not in terms of operation time, hospital stay, fusion time, and loss of correction at the final follow-up. CONCLUSION: The anterior and posterior approaches are equally good methods for treatment of thoracolumbar tuberculosis. The anterior approach results in less blood loss, whereas posterior instrumentation is better suited for correction of kyphotic angle.

The spectrum of tuberculosis of the spine in pediatric age group: a review.

INTRODUCTION: Pediatric spinal tuberculosis is characterized by rapid bone destruction and carries the risk of rapid onset neurological deficits and severe deformity of the spine. Behavior of spinal deformity over time is affected by growth of spine. Owing to this dynamic behavior of pediatric spinal tuberculosis both in active phase and in healed phase, it presents with challenges which are quite different from adults with caries spine. A clinician must have high index of suspicion for accurate and early diagnosis of spinal tuberculosis in the pediatric population and should also have a thorough knowledge of differences in natural history between adult and pediatric spinal tuberculosis. DISCUSSION: This is based on the senior author's experience of dealing with tuberculosis of the spine in children over the last two decades. Recent advances in field of rapid diagnosis of tuberculosis based on nuclear material-related diagnostic tests have further improved the management of tuberculosis. At the same time, the basic treatment principles remain the same. However, the threshold for surgical vs conservative treatment have subtle differences when compared to adult population. The importance of long-term follow-up after treatment must be appreciated. CONCLUSION: Tuberculosis in the spine in children needs early attention. Prompting to diagnostic and medical therapy measures can avoid neurological sequellae and delayed deformity.

Treatment of Lumbar Tuberculosis by Mini-Open Anterior Approach Focal Cleaning Combined with Posterior Internal Fixation.

BACKGROUND The aim of this study was to evaluate the efficiency and clinical outcomes of mini-open anterior approach focal cleaning combined with posterior internal fixation compared to conventional anterior extraperitoneal approach focal cleaning combined with posterior internal fixation in the treatment of lumbar tuberculosis (TB). MATERIAL AND METHODS Medical records from 124 patients were collected from February 2010 to April 2015; patients were divided into two groups: group A (mini-open anterior approach focal cleaning combined with posterior internal fixation) and group B (conventional anterior extraperitoneal approach focal cleaning combined with posterior internal fixation in period I). The data on postoperative mechanical ventilation time, preoperative, postoperative, and last follow-up Cobb angle, visual analog scale (VAS), erythrocyte sedimentation rate (ESR), and Frankel classification were collected and analyzed. Operative complications, internal stability, and bone graft fusion were also observed. RESULTS All patients were followed-up for 12 to 36 months (average 22.5 months). Seven cases (five in group A and two in group B) had side psoas abscess and were cured after secondary drainage surgery. The rest of the cases were all cured after primary surgery, with no formation of sinus, incisional hernia, cerebrospinal fluid leakage, or recurrence of spinal TB, with no TB symptoms. Bone graft fusion ranged from 3 to 8 months (average 4.7 months). Compared to group B, group A, which had less time on postoperative mechanical ventilation, had a higher VAS score. Both groups had distinct improvements in Cobb angle, ESR, and Frankel classification after surgery. CONCLUSIONS Treating lumbar TB by mini-open anterior approach focal cleaning combined with posterior internal fixation was safe and effective.

Demographics of tuberculosis of spine and factors affecting neurological improvement in patients suffering from tuberculosis of spine: a retrospective analysis of 312 cases.

OBJECTIVES: The purpose of the study was to study demographics of tuberculosis of spine and analyze factors that might affect neurological improvement in such patients. METHODS: Of the 638 suspected cases of spinal tuberculosis, 312 cases with confirmed diagnosis with at least 1-year follow-up were selected for retrospective analysis. Two hundred cases who presented with neurological deficit were further divided into three groups-completely improved, partially improved and no improvement according to American Spinal Injury Association impairment scale (AIS) grading. All continuous variables and categorical variables were compared across groups. RESULTS: A total of 209 (66.99%) patients had typical clinical presentation. A total of 264 (84.62%) had typical magnetic resonance imaging (MRI) presentation. Among 356 involved vertebrae, thoracic levels (T1-10) were most commonly affected in 163 (45.78%) followed by thoracolumbar (T11-L2) vertebrae in 98 (27.52%). In 250 patients (80.12%), disease was restricted to one or two adjoining vertebrae. At presentation, 112 (35.89%) patients were neurologically intact, whereas 97 (31%) were AIS D, 65 (20.83%) were AIS C, 8 (2.5%) were AIS B and 30 (9.61%) were AIS A. On statistical analysis, although three groups of patients with complete improvement, partial improvement and no improvement were similar in age, sex, radiological presentation, and co-morbidities and the presence of pulmonary tuberculosis, they were significantly different with regard to the levels of vertebral involvement, AIS grade at presentation, bladder and bowel involvement and its duration. CONCLUSIONS: In management of patients suffering from tuberculosis of spine, levels of vertebral involvement, AIS grade at presentation, bladder and bowel involvement and its duration significantly affect the final neurological improvement.

The efficacy of local continuous chemotherapy and postural drainage in combination with one-stage posterior surgery for the treatment of lumbar spinal tuberculosis.

BACKGROUND: The objective of this study was to compare the outcomes of one-stage posterior surgery involving debridement, bone grafting, and instrumentation with and without local continuous chemotherapy and postural drainage for the treatment of lumbar spinal tuberculosis. METHODS: From January 2009 to January 2013, 109 patients with lumbar spinal tuberculosis were treated in our center using a posterior surgical approach. Patients underwent one-stage posterior debridement, bone grafting, and instrumentation, without (group A) and with (group B) local continuous chemotherapy and postural drainage. Clinical and radiographic results for the two groups were analyzed and compared. Clinical efficacy was evaluated based on surgery duration and blood loss. The Frankel scale was used to evaluate neurological function. A visual analog scale was used to assess low back pain. Bone graft fusion and instrumentation failure were monitored by radiography, and tuberculosis activity was monitored by erythrocyte sedimentation rate (ESR) and C-reactive protein testing. RESULTS: Groups A and B contained 52 and 57 patients, respectively. Patients were followed for 18-36 (mean, 26.64 ± 4.2) months. All bone grafts ultimately fused, but the fusion rate was significantly more rapid in group B [6.4 ± 0.5 (range, 5-10) months] than in group A [8.9 ± 0.6 (range, 6-12) months; P < 0.05]. At 6 weeks postoperatively, ESR levels differed significantly between groups A and B (24.6 ± 1.5 vs. 16.3 ± 1.1 mm/h; P < 0.05). ESR levels normalized in both groups at 16 weeks. CONCLUSIONS: Local continuous chemotherapy and postural drainage effectively eliminated infection foci caused by abscess remnants and accelerated interbody bone fusion in patients with lumbar spinal tuberculosis undergoing one-stage posterior surgery involving debridement, bone grafting, and instrumentation.

Early diagnosis of spinal tuberculosis.

Spinal tuberculosis (STB) is a common manifestation of extrapulmonary tuberculosis (TB). STB accounts for around 2% of all cases of TB and around 15% of extrapulmonary TB cases. The World Health Organization has proposed a global strategy and targets for TB prevention, care, and control after 2015. Under this strategy, patients will receive standard care according to the recommendations and guidelines after confirmation of STB diagnosis. However, current recommendations and guidelines focus on disease and medication therapy management, and recommendations for early detection or decision-making algorithms regarding STB are lacking. In this review, we identified five key components for early diagnosis: (1) risk factors for STB; (2) common symptoms/signs of STB; (3) significant neuroradiological findings of STB; (4) significant laboratory findings of STB, including positive interferon-γ release assays and nonpyogenic evidence in initial laboratory data; and (5) significant clinical findings of STB. Individualized consideration for each patient with STB is essential, and we hope that the algorithm established in this review will provide a valuable tool for physicians who encounter cases of STB.

Concomitant metastatic cutaneous tuberculous abscesses and Pott disease in an immunocompetent patient.

Tuberculosis affects one-third of the world's population. The incidence of extrapulmonary tuberculosis including cutaneous and skeletal manifestations has increased in the last decades. The authors report a clinical case of concomitant metastatic cutaneous abscesses and Pott disease in an immunocompetent patient, a rare presentation of tuberculosis.

Spinal tuberculosis, natural history of disease, classifications and principles of management with historical perspective.

PURPOSE: To describe the natural history spinal tuberculosis, classifications and principles of management based upon the grading of the neurological deficit. METHODS: Review of literature was conducted with the aim to provide the clinico-radiological correlation of the natural history of spinal tuberculosis in different stages. Management strategy is developed based upon the severity of the neurological deficit. RESULTS: A five stage natural history of spinal tuberculosis is described. Stage of neurological involvement is further divided into 4 grades, predominantly on the basis of progressively increasing motor deficits as negligible, mild, moderate and severe with sensory and autonomic dysfunctions. Suitable principles of management with role of rest, braces, chemotherapy and surgery are discussed. Neurological deficit grading based management is developed. Grade 1 and 2, conservative treatment, grade 3, gray zone and grade 4, operative treatment is emphasized. CONCLUSION: The five stages of natural history of tuberculosis of spine have been developed from the clinician's point of view. Management of tuberculosis of spine, in general, it is no different than management of soft tissue tuberculosis, in HIV negative or positive patients. Role of surgery is very limited. Management of tubercular paraplegia, based upon the grading of paraplegia is simple, logical, efficient and easy to understand and remember by any orthopedic surgeon.

Characteristics and Clinical Outcome of Bone and Joint Tuberculosis From 1994 to 2011: A Retrospective Register-based Study in Denmark.

BACKGROUND: Most information on bone-joint (BJ)-tuberculosis is based on data from high-incidence areas. We conducted a nationwide register-based analysis of BJ-tuberculosis in Denmark from 1994 to 2011. METHODS: We linked data from the national tuberculosis surveillance system on BJ-tuberculosis, hospital records, the Danish Hospital and Civil Registration System. RESULTS: We identified 282 patients with BJ-tuberculosis, 3.6% of all tuberculosis cases (n = 7936). Spinal tuberculosis was found in 153 of 282 patients (54.3%); 83.3% of all cases were immigrants. Danes were older and had higher Charlson comorbidity index scores than immigrants (P < .01). C-reactive protein and erythrocyte sedimentation rates were elevated in most cases. Median time to diagnosis after first hospital contact was 19.5 days for spinal tuberculosis and 28 days for other forms of BJ-tuberculosis (P = .01). Of patients with spinal tuberculosis, 54/133 (40.6%) had neurologic deficits at admission and 17.3% presented with cauda equina. Diagnosis was culture verified in 87%. (Resistance to any drug was found in 10.2%). Median time on antituberculous treatment for patients with spinal and other forms of BJ-tuberculosis was 9 months and 7 months, respectively (P < .01). Surgery was required in 44.4% patients with spinal tuberculosis and in 32.6% patients with other forms of BJ-tuberculosis (P = .04). Sequelae were reported in 57.5% of patients with spinal tuberculosis and 29.1% of patient with other forms of BJ-tuberculosis (P < .01). One-year mortality was 25.5% among Danes compared with 1.3% among immigrants (P < .01). CONCLUSIONS: BJ-tuberculosis was rare and seen mainly in younger immigrants in Denmark. More than half of cases were spinal tuberculosis, presenting with more severe symptoms and worse outcome, compared with other forms of BJ-tuberculosis.

Minimally invasive retroperitoneoscopic surgery for psoas abscess with thoracolumbar tuberculosis.

BACKGROUND AND STUDY AIMS: Minimally invasive retroperitoneoscopic surgery (MIS) for psoas abscess (PA) in patients with thoracolumbar tuberculosis is not well-illustrated and has not reached the status of being fully clinically assessed when we review the English literatures. The aim of this study is to introduce and investigate on efficacy and feasibility of MIS (retroperitoneoscopic technique) for PA in patients with thoracolumbar tuberculosis. PATIENTS AND METHODS: From January 2008 to 2013, 39 consecutive patients of the diagnosis of PA with thoracolumbar tuberculosis received the debridement of abscesses and cavity walls of abscesses by the retroperitoneoscopic technique (MIS) in combination with anti-tuberculosis chemotherapy. Medical records and follow-up data were retrospectively studied. CRP and ESR of every patient preoperatively and postoperatively were analyzed RESULTS: Immediate relief in clinical symptoms and signs, and amelioration in imaging and laboratory examinations were obviously observed in all the patients. The follow-up had proceeded for 12-48 (mean 23) months. No complication was observed during the follow-up postoperatively. CONCLUSIONS: The retroperitoneoscopic technique for PA gain advantages in terms of shorter hospital stay, minimal invasiveness, absence of radiation, quicker recovery to daily life compared with percutaneous drainage, and anterior or posterior debridement surgery. Despite the technique not been fully clinically proved, it seems to be a recommended option as an effective diagnostic and therapeutic technique for PA, especially with massive or complicated PA.
