Impression fracture of the lateral condyle of tibial plateau complicated by acute peri-implant infection: a case report

Introduction. Deep infection after open osteosynthesis of tibial plateau fractures occurs in 9.9%. This rate is significantly higher than in surgical treatment of closed injuries of other localizations. Many authors consider it necessary to improve management protocols for patients with complex plateau fractures in order to minimize or prevent the development of infectious complications. Aims of the study: 1) to discuss the treatment tactics of a patient with an intraarticular fracture of the tibial plateau after osteosynthesis complicated by the development of early deep surgical site infection (SSI), using clinical case as an example; 2) to carry out the analysis of medical care defects. Case description. A 71-year-old patient with compromised somatic status underwent osteosynthesis with a buttress plate and allogeneic bone grafting of the metaphyseal defect on the 12th day after injury. In 7 days after the occurrence of signs of infection, a revision surgery was performed. Later, a number of consecutive revisions were performed due to recurrences of the infectious process. The complex of measures against SSI included the use of vacuum drainage systems and antibacterial spacers. As a result, the wounds had healed. Two years after the injury, the patient had a good functional result. Conclusion. The presented clinical case has shown that even if the treatment tactic for early peri-implant infection is chosen correctly, there are several defects in our routine practice. First of all, inaccurate sampling of material for bacteriological study and inadequate duration of antibacterial therapy are to be mentioned. To successfully treat infectious complications of osteosynthesis, a team of like-minded specialists including traumatologists as well as physicians, microbiologists and clinical pharmacologists is needed. Undoubtedly, surgical treatment of fractures might develop into infectious complications. Their diagnosis and treatment are often accompanied by a number of various mistakes. The most important points are early radical revision of the postoperative wound, etiotropic antibacterial therapy, maintaining stability of fixation after primary osteosynthesis. If these standards are complied with, the outcome of surgical treatment might be satisfying even with such a severe complication as peri-implant infection. At the same time, we are planning further researches aimed at improving algorithms and tactics for surgical treatment of infectious complications, reducing surgery trauma level and upgrading quality of primary osteosynthesis.

Chronic pyogenic spondylitis in patients with spinal gout: a case series and literature review

Background. Spinal gout is a rare and poorly described group of noninfectious inflammatory spinal lesions characterized by the deposition of monosodium urate crystals in the epidural space, paravertebral soft tissues, and by facet joints damage. There is no systematized data on the course of infectious spondylitis and spinal gout in the literature. The aim of the study — to present long-term outcomes of surgical treatment of chronic pyogenic spondylitis in patients with spinal gout and systematize the literature data on the issue. Methods. The clinical part of the study included 6 consecutively operated patients in the period from 2018 to 2021. The diagnosis of spinal gout and chronic pyogenic spondylitis was verified according to the results of histologic and bacteriologic studies of surgical material. Catamnesis accounted for at least 12 months. We studied the peculiarities of clinical and laboratory, radiological and histologic manifestations of the disease. Literature data systematization was carried out in the databases PubMed, Google Scholar, eLIBRARY from 2013 to 2023. Inclusion criteria: level of evidence II B-IV, catamnesis more or equal to 6 months, information on diagnostic and treatment measures. Results. The average age of the patients was 55±9 years. The duration of the diagnostic pause was 8±5 years. Multisegmented lesions of the lumbar (n = 6) spine prevailed. According to the classification of Pola E. et al. (2017) the following types of spondylitis were identified: B.3 (n = 1), C.1 (n = 1), C.3 (n = 2) and C.4 (n = 2). The clinical manifestation was dominated by chronic back pain with an intensity of 6,1±1,4 VAS scores. Neurologic disorders of the lower extremities and pelvic (ASIA scale) corresponded to types B (n = 1) and C (n = 4). The type of surgery: three-column reconstruction through combined approach in 2 cases and isolated anterior column reconstruction in 2 cases, 360° fusion in 1 case, and debridement of the epidural space and anterior column through posterior approach in 1 case. The follow-up results show the absence of recurrence of spondylitis in 4 cases, in 2 patients there were postoperative complications that required revision, after which no recurrence of spondylitis was noted. We selected 17 publications for literature review. Conclusion. The combination of chronic pyogenic spondylitis and spinal gout is a rare and poorly described pathology in the literature. Long therapeutic pause, chronic character of vertebrogenic pain syndrome in combination with increased uric acid level and formation of tophi of vertebral localization are distinctive features of the disease. Neurologic disorders with the combination of spondylitis and gout result from stenosis of the spinal canal due to two factors — epidural abscesses and tophi. Achieving local control of the combined pathology is possible with a combination of surgical intervention and long-term administration of hypouricemic drugs.

Immediate and long-term outcomes of surgical treatment in patients with retroperitoneal and abdominal desmoid fibromatosis: A retrospective study

Background. The main method of treatment of desmoid fibromatosis is surgical, especially in patients with symptomatic disease or in cases of progression during the Look and Stay period. Due to the rarity of the disease, different localization, unpredictability of the clinical course, the lack of generally accepted clear criteria for choosing a treatment method and/or a sequence of treatment methods, the determination of prognostic criteria for the course of the disease is of great scientific and practical interest. Aim. To study the immediate and long-term outcomes of surgical treatment in patients with retroperitoneal and abdominal desmoid fibromatosis. Materials and methods. The study analyzed the data of 121 patients with histologically verified retroperitoneal and abdominal desmoid fibromatosis who underwent surgical treatment at the Blokhin National Medical Research Center of Oncology from 1999 to 2022. Results. In 89% of cases, desmoid tumors are resectable; however, resections of adjacent organs are often required to remove the tumor mass completely. The frequency of combined interventions in the abdominal and retroperitoneal groups was 7.0 and 60.4%, respectively. Tumor cells along the edge of the incision are identified in 15.8% of patients, including 10% of patients with macroscopically detectable residual tumors. Surgical treatment of patients with desmoid tumors is associated with an acceptable complication rate and provides high rates of overall and relapse-free survival. Risk factors for disease-free survival of operated patients are retroperitoneal localization, multicentric tumor growth, and R2 category. Conclusion. The treatment of patients with retroperitoneal and abdominal desmoid tumors should be carried out in specialized clinics with sufficient experience in performing surgical interventions, including combined ones. The treatment approach in patients with desmoid tumors should be selected by a multidisciplinary team based on personalized oncological and functional prognoses in accordance with the prognostic risk groups.

Vagus Nerve Stimulation Therapy in Epilepsy: An Overview of Technical and Surgical Method, Patient Selection, and Treatment Outcomes

Epilepsy affects over 65 million people worldwide. One-third of people with epilepsy do not respond to medication and may benefit from surgery. Vagus nerve stimulation (VNS) is the first neuromodulation therapy for the treatment of drug-resistant epilepsy. This method is used in combination with anti-seizure medications in adults and in the pediatric population. VNS has also been demonstrated to have benefits for some epilepsy comorbidities, such as depression, and can be used in combination with other neuromodulation therapies in epilepsy. The authors present an overview of VNS physiology, patient selection, surgery and risks, neuromodulation therapy, and application to epilepsy comorbidities.

Segmental Spinal Aplasia: Anatomical Variations and Treatment Insights.

Retrospective Cohort Study. The study aimed to analyze anatomical variants of segmental spinal aplasia (SSA) and investigate factors influencing surgical treatment outcomes, with a specific focus on the incidence of complications. The study focused on patients with SSA treated at a single medical center, with over two years of follow-up. Neurological function changes were evaluated using the modified Japanese Orthopedic Scale (mJOA). Functional independence was measured using the Functional Independence Measure (FIM/WeeFIM) scale, and complications, well-being, and reoperation instances were documented. Statistical analyses used ANOVA and Kruskal-Wallis test. The predominant localization of SSA in 36 own cases occurs near or at the level of the thoracolumbar junction, often accompanied by significant spinal cord narrowing and a low position of the conus medullaris. Additionally, it frequently presents with aplasia of the lower ribs. Cervicothoracic SSA was more commonly associated with segmentation disorders (P = .04). The most common early complications were wound problems (17%) and neurological deterioration (17%); the most common late complications were: non-fusion (34%); 38% of patients required one or more revision surgery. The type, age of surgery, level of surgery, and initial neurological deficient did not significantly influence the incidence of complications or neurological and functional outcomes. SSA, a range of anomalies appearing early in childhood, progresses gradually. Surgery involves vertebrectomy followed by interbody fusion and screw fixation, guided by neurophysiological monitoring. Surgery is recommended for worsening neurological symptoms, but conservative options like bracing can be considered, due to a high risk of complications.

Short‐term outcomes of surgical treatment for primary ileocaecal Crohn's disease: Results of the Crohn's(urg) study, a multicentre, retrospective, comparative analysis between inflammatory and complicated phenotypes

AbstractAimRecent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications of the disease. The aim of this study was to compare short‐term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes.MethodA retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres. Patients were divided into two groups according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short‐term results were compared.ResultsA total of 2013 patients were included, with 291 (14.5%) in the ICD group. No differences were found between the groups in time from diagnosis to surgery. CCD patients had higher rates of low body mass index, anaemia (40.9% vs. 27%, p < 0.001) and low albumin (11.3% vs. 2.6%, p < 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3% vs. 93.1%, p = 0.001) and higher conversion rates (9.3% vs. 1.9%, p < 0.001). CCD patients had a longer hospital stay and higher postoperative complication rates (26.1% vs. 21.3%, p = 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1% vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgery (OR 3.44, p = 0.001) and the requirement for multiple intraoperative procedures (OR 8.39, p = 0.030).ConclusionIndication for surgery in patients who present with an inflammatory phenotype of CD was associated with better outcomes compared with patients operated on for complications of the disease. There was no difference between groups in time from diagnosis to surgery.

Results of the use of an integrated risk scale for postoperative complications in patients with colorectal cancer

Inroduction. Polymorbidity significantly increases the risk of complications in the early postoperative period, especially in patients with colorectal cancer, taking into account the initial nutritional status disorder. At present, several scales of postoperative complications risk assessment (POSSUM, RCRI, MUST) are used, but they do not fully meet the needs of modern oncosurgery, so we consider it necessary to compare their effectiveness and propose a new integrated scale.Aim. To establish the most significant factors influencing the outcome of surgical treatment and length of hospitalization in comorbid patients with colon cancer with the development of a surgical risk assessment scale that is most adapted for this group of patients.Materials and methods. We analyzed the data of hospital charts of patients undergo surgery for colorectal cancer in the oncoproctologic department of the S. P. Botkin State Clinical Hospital of the Moscow Healthcare Department in the period from 2019 to 2022. Inclusion criteria: histologically verified colorectal adenocarcinoma; colorectal cancer in stage cT4, cN0, cM0 or cT1–4, cN1–2, cM0; presence of one or more concomitant diseases in the patient. Exclusion criteria: presence of distant metastases of colorectal cancer; absence of confirmed comorbidities; early forms of colorectal cancer (cT1–2, cN0). All patients were assessed for risk of perioperative complications using ASA, POSSUM, MUST, and RCRI scales. The study endpoints were number of days in intensive care, number of days of hospitalization, and 30-day mortality. An Excel database with POSSUM, RCRI, and MUST scale calculators was created for the study. The evaluation of parameters influencing the outcome of hospitalization was performed using ROC analysis and correlation analysis using Pearson’s criterion. To identify the most sensitive parameters affecting the outcome of hospitalization, commonly used calculators were studied in detail.Results. 200 patient records were analyzed. The results of treatment were compared with the data obtained using the postoperative risk scales POSSUM, MUST, RCRI. A comparative analysis of the scales presented above with our proposed integral scale of postoperative complications risk assessment was carried out. It was found that the parameters of our proposed integral scale showed the highest sensitivity (Se >70 %) and specificity (Sp >70 %) to the risk of postoperative complications. Our proposed integral scale showed a moderate correlation with the age of patients (r = 0.475, p = 0.01) and preoperative weight loss (r = 0.592, p = 0.01), as well as a high correlation with POSSUM (r = 0.649, p = 0.01; r = 0.852, p = 0.01) and MUST (r = 0.655, p = 0.01).Conclusion. The developed scale for assessment of surgical risk in comorbid patients with colorectal cancer showed a higher correlation with the outcome of surgical treatment than similar known scales, which indicates its effectiveness and possibility of application in clinical practice after its validation in prospective studies.

Endovascular treatment of patients with distal aneurysms of cerebellar arteries

Aim. To evaluate short- and long‑term angiographic and clinical outcomes of endovascular treatment of patients with distal aneurysms of cerebellar arteries.Materials and methods. The outcomes of endovascular treatment of 6 patients with distal aneurysms of cerebellar arteries who underwent surgery at the Neurosurgical Division No. 3 of the Polenov Russian Research Institute of Neurosurgery between January 1 of 2017 and March 31 of 2023 were analyzed.Results. The following endovascular methods were used: occlusion of the aneurysm sac using only detachable coils (n = 2); occlusion using stent‑assisted coiling (n = 3); deconstructive intervention with occlusion of the main artery (n = 1). In 1 of 2 cases of coil‑only aneurysm occlusion, additional stent‑assisted occlusion was performed due to recurrence. Among 6 aneurysms, 1 (16.65 %) aneurysm was radically excluded from the blood flow (class А); 4 (66.7 %) were excluded subtotally (class B); 1 (16.65 %) was excluded partially (class С). Control angiography at least 6 months after showed radical exclusion of the aneurysm from the blood flow (class A) in 5 (83.3 %) patients, subtotal exclusion (class В) in 1 (16.7 %) patient. Clinical outcome was excellent in 5 (83.3 %) patients (0 points per the modified Rankin scale); in 1 patient after deconstructive surgery, augmentation of neurological symptoms with following partial regression was observed (2 points per the modified Rankin scale). Complications during deconstructive surgery were observed in 1 (16.7 %) patient.Conclusion. Deconstructive surgery of the distal aneurysms of cerebellar arteries can be associated with high risk of postoperative ischemic complications with development of persisting neurological deficit. Surgical interventions with preservation of the artery lumen (including reconstructive surgeries) should be the method of choice in endovascular treatment of distal aneurysms of cerebellar arteries due to minimal risk of ischemic complications and improved clinical outcomes of surgical treatment.

Prognostic Factors and Clinical Outcomes of Surgical Treatment of Major Thoracic Trauma.

Major thoracic trauma represents a life-threatening condition, requiring a prompt multidisciplinary approach and appropriate pathways for effective recovery. While acute morbidity and mortality are well-known outcomes in thoracic-traumatized patients, long-term quality of life in patients surviving surgical treatment has not been widely investigated before. Between November 2016 and November 2023, thirty-two consecutive patients were operated on because of thoracic trauma. Age, sex, comorbidities, location and extent of thoracic trauma, Injury Severity Score (ISS), Abbreviated Injury Scale (AIS), Organ Injury Scale (OIS), intra and extrathoracic organ involvement, mechanism of injury, type of surgical procedure, postoperative complications, ICU and total length of stay, immediate clinical outcomes and long-term quality of life-by using the EQ-5D-3L scale and Numeric Rate Pain Score (NPRS)-were collected for each patient Results: Results indicated no significant difference in EQOL.5D3L among patients with thoracic trauma based on AIS (p = 0.55), but a significant difference was observed in relation to ISS (p = 0.000011). ISS is correlated with the EQOL.5D3L questionnaire on long-term quality of life, representing the best prognostic factor-in terms of long-term quality of life-in patients surviving major thoracic trauma surgical treatment.

Surgical outcomes for non-small cell lung carcinoma by race and surgical facility types in the United States.

11167 Background: Successful outcomes of surgical treatment of cancer requires expertise and high-quality supportive services for surgical care. Previous studies have shown that case volume and availability of other in-house supportive services affect surgical outcomes. Latest studies have shown that this gap has now significantly reduced. Issues related to access, availability of funding for latest technologies and continuous medical education still exist and likely still impact the surgical outcomes. The objective of the study is to understand the impact of surgical center related factors on survival outcomes for cancer patients based on race and other demographic features. Methods: We conducted a retrospective analysis of patients diagnosed with Stage I-III Non-small cell lung cancer (NSCLC) between 2004 to 2020 using the National Cancer Database (NCDB). Patients were divided into 4 cohorts of NCDB assigned facility type (Community Cancer Program, Comprehensive Community Cancer Program, Academic/Research Program, Integrated Network Cancer Program). Racial and other demographic data was analyzed for each of the facility types. Differences in categorical variables were evaluated using a Chi-square test. Results: 298,393 adenocarcinoma and 129,144 squamous cell carcinoma patients underwent surgery for NSCLC between 2004-2020. 326,798 patients with clinical stages I-III were selected for the analysis. Most surgeries were performed at the academic/research programs and comprehensive community programs. Utilization of each facility type was uniform across all races. The 30-day mortality rate was lowest for the academic/research programs (Community Cancer Program 3.1%, Comprehensive Community Cancer Program 2.6%, Academic/Research Program 1.8%, Integrated Network Cancer Program 2.3%; p=0.000). 30-day mortality rate was higher for American Indian, Aleutian, or Eskimo racial subgroups amongst all age-groups at all the surgical facility types especially for Stage IIIB NSCLC (White: 6%, Black: 3.4%, American Indian, Aleutian, or Eskimo: 14.3%, p=0.006). For each race, the 30-day mortality rate was better at the academic/research programs. Females had lower 30-day mortality for all racial subgroups. Having private insurance was associated with the lowest 30-day mortality rate. This was noted for all races across all the facility types. Lower income status was associated with higher mortality rates across all facility types. This difference was statistically significant for white patients. Majority of patients had less than 10 days of length of stay at all the surgical facility types. Conclusions: Outcomes of NSCLC surgery are significantly better at academic/research programs where a higher number of procedures are performed and access to latest surgical technologies is available. Short-term mortality rates are higher for American Indian, Aleutian, or Eskimo racial subgroup.

Percutaneous thermal radiofrequency rhizotomy of L2-S1 spinal nerve roots in children with cerebral palsy.

This study presents the results of an evaluation of the effectiveness of percutaneous thermal radiofrequency (RF) ablation of spinal nerve roots to reduce spasticity and improve motor function in children with cerebral palsy (CP). A retrospective analysis was conducted on the surgical treatment outcomes of 26 pediatric patients with severe CP (Gross Motor Function Classification System levels IV-V). The assessment protocol included muscle tone assessment using the modified Ashworth scale (MAS), evaluation of passive and active range of motion, gait video recording, and locomotor status evaluation using the Gross Motor Function Measure (GMFM)-88 scale. Thermal RF rhizotomy (ablation of spinal nerve roots) was performed on all patients at the L2-S1 levels at 70°C for 90 seconds. The statistical data analysis was conducted using the t-test and Mann-Whitney U-test. A p value < 0.05 was considered statistically significant. Before the operation, the average level of spasticity in the lower-limb muscles of all patients was 3.0 ± 0.2 according to the MAS. In the early postoperative period, the spasticity level in all examined muscle groups significantly decreased to a mean of 1.14 ± 0.15 (p < 0.001). In the long-term postoperative period, the spasticity level in the examined muscle groups averaged 1.49 ± 0.17 points on the MAS (p < 0.001 compared to baseline, p = 0.0416 compared to the early postoperative period). Despite the marked reduction of spasticity in the lower limbs, no significant change in locomotor status according to the GMFM-88 scale was observed in the selected category of patients. In the long-term period, during the control examination of patients, the GMFM-88 level increased on average by 3.6% ± 1.4% (from 22.2% ± 3.1% to 25.8% ± 3.6%). The findings of this study offer preliminary yet compelling evidence that RF ablation of spinal nerve roots can lead to a significant and enduring decrease in muscle tone among children with severe spastic CP. Further studies and longer-term data of the impact on functionality and quality of life of patients with CP after spinal root RF ablation are needed.

Validation of a 3D-printed model of cryptoglandular perianal fistulas.

Visualising the course of a complex perianal fistula on imaging can be difficult. It has been postulated that three-dimensional (3D) models of perianal fistulas improve understanding of the perianal pathology, contribute to surgical decision-making and might even improve future outcomes of surgical treatment. The aim of the current study is to investigate the accuracy of 3D-printed models of perianal fistulas compared with magnetic resonance imaging (MRI). MRI scans of 15 patients with transsphincteric and intersphincteric fistulas were selected and then assessed by an experienced abdominal and colorectal radiologist. A standardised method of creating a 3D-printed anatomical model of cryptoglandular perianal fistula was developed by a technical medical physicist and a surgeon in training with special interest in 3D printing. Manual segmentation of the fistula and external sphincter was performed by a trained technical medical physicist. The anatomical models were 3D printed in a 1:1 ratio and assessed by two colorectal surgeons. The 3D-printed models were then scanned with a 3D scanner. Volume of the 3D-printed model was compared with manual segmentation. Inter-rater reliability statistics were calculated for consistency between the radiologist who assessed the MRI scans and the surgeons who assessed the 3D-printed models. The assessment of the MRI was considered the 'gold standard'. Agreement between the two surgeons who assessed the 3D printed models was also determined. Consistency between the radiologist and the surgeons was almost perfect for classification (κ = 0.87, κ = 0.87), substantial for complexity (κ = 0.73, κ = 0.74) and location of the internal orifice (κ = 0.73, κ = 0.73) and moderate for the percentage of involved external anal sphincter in transsphincteric fistulas (ICC 0.63, ICC 0.52). Agreement between the two surgeons was substantial for classification (κ = 0.73), complexity (κ = 0.74), location of the internal orifice (κ = 0.75) and percentage of involved external anal sphincter in transsphincteric fistulas (ICC 0.77). Our 3D-printed anatomical models of perianal fistulas are an accurate reflection of the MRI. Further research is needed to determine the added value of 3D-printed anatomical models in preoperative planning and education.

Marginal Ulcer Perforation after One Anastomosis Gastric Bypass: Surgical Treatment and Two-Year Outcomes.

Background: Marginal ulcer (MU) perforation is a chronic complication after One-anastomosis Gastric Bypass (OAGB). This study's purpose was to analyze patients undergoing OAGB revision due to MU perforation and describe the two-year outcomes. Methods: A retrospective analysis of a database in a single-tertiary hospital. All patients undergoing surgical revision due to MU perforation were included. Results: During the study period, 22 patients underwent OAGB revision due to MU perforation. The rate of MU perforation was 0.98%. The median age was 48 years and there were 13 men (59%). The median time from OAGB to MU perforation was 19 months with a median total weight loss of 31.5%. Nine patients (41%) were smokers. Omental patch (±primary closure) was performed in 19 patients (86%) and three patients (14%) underwent conversion to Roux-en-Y gastric bypass (RYGB). At a median follow-up of 48 months, three patients (14%) had recurrent MU diagnosis, of which one had a recurrent MU perforation. Four patients (18%) underwent conversion to RYGB during follow-up. Conclusions: MU perforation is a chronic complication after OAGB. In this cohort, most patients were men and likely to be smokers. Omental patch was effective in most cases. Recurrent MU rates at two years follow-up were acceptable.

ANTEGRADE METHODS OF BILIARY DECOMPRESSION IN TUMOR OBSTRUCTION OF THE BILIARY TRACT

Percutaneous transhepatic endoscopic ultrasound-guided intervention is a crucial method for addressing mechanical jaundice. This technique for restoring bile outflow enables the resolution of several medical and diagnostic issues with minimal invasiveness and fewer complications compared to traditional open surgical treatments. Most often, antegrade cholangiostomy is used in oncological practice, where the variety of clinical situations determines the indications for performing this intervention in different variants and with different goals. According to the world literature, at the moment, sufficient experience of transdermal technologies has been accumulated, their application in clinical practice has been worked out, which allows to recognize them, to a certain extent, as routine. The purpose of this work is to optimize biliary decompression in patients with tumor obstruction of the biliary tract, to improve the prevention of complications, to enhance the immediate results of treatment and the quality of life for this group of population. The study analyzed the examination and surgical treatment outcomes of 64 patients with tumor-related mechanical jaundice treated in surgical hospitals from 2017 to 2023. All patients underwent antegrade biliary drainage procedures, specifically percutaneous transhepatic cholangiostomy and bile duct stenting under ultrasound guidance, to achieve biliary decompression. Percutaneous transhepatic endoscopic interventions have become the primary method for biliary decompression in cases of bile duct obstruction due to tumors. These procedures, particularly for malignant tumors, are associated with relatively few complications and low mortality rates.

Surgical Treatment Outcomes of Anterior-Only Correction and Reconstruction for Severe Cervical Kyphotic Deformity with Neurofibromatosis-1: A Retrospective Study with a 5-Year Follow-Up.

Currently, anterior-only (AO), posterior-only, and combined anterior-posterior spinal fusions are common strategies for treating cervical kyphosis in patients with neurofibromatosis-1 NF-1. Nevertheless, the choice of surgical strategy remains a topic of controversy. The aim of our study is to evaluate the safety and effectiveness of anterior decompression and spinal reconstruction for the treatment of cervical kyphosis in patients with NF-1. Twelve patients with NF-1-associated cervical kyphotic deformity were reviewed retrospectively between January 2010 and April 2020. All patients underwent AO correction and reconstruction. The X-ray was followed up in all these patients to assess the preoperative and postoperative local kyphosis angle (LKA), the global kyphosis angle (GKA), the sagittal vertical axis, and the T1 slope. The visual analog scale score, Japanese Orthopedic Association (JOA) score, and neck disability index (NDI) score were used to evaluate the improvement inclinical symptoms. The results of the difference in improvement from preoperatively to the final follow-up assessment were assessed using a paired t-test or Mann-Whitney U-test. The LKA and GKA decreased from the preoperative average of 64.42 (range, 38-86) and 35.50 (range, 10-81) to an average of 16.83 (range, -2 to 46) and 4.25 (range, -22 to 39) postoperatively, respectively. The average correction rates of the LKA and GKA were 76.11% and 111.97%, respectively. All patients had achieved satisfactory relief of neurological symptoms (p < 0.01). JOA scores were improved from 10.42 (range, 8-16) preoperatively to 15.25 (range, 11-18) at final follow-up (p < 0.01). NDI scores were decreased from an average of 23.25 (range, 16-34) preoperatively to an average of 7.08 (range, 3-15) at the final follow-up (p < 0.01). Anterior-only correction and reconstruction is a safe and effective method for correcting cervical kyphosis in NF-1 patients. In fixed cervical kyphosis cases, preoperative skull traction should also be considered.

Risk factors for carotid endarterectomy in the early period of stroke

The OBJECTIVE was to identify significant risk factors of complications after carotid endarterectomy in the acute period of ischemic stroke, thus improving the outcomes of surgical treatment of symptomatic internal carotid artery stenosis.METHODS AND MATERIALS. The results of treatment of 776 patients after carotid endarterectomy in the acute period of stroke operated in the State Budgetary Institution of Tuberculosis «Regional Clinical Hospital № 2» were subjected to the factor analysis. catamnesis of the disease was traced for at least one year from the surgical intervention.RESULTS. Repeated ispilatory stroke occurred in 13 patients. Significant factors were tortuosity of the target artery (OR, 6.94; 95 % cI=2.21–21.86; p=0.003), aneurysm in the tortuosity zone (OR, 138.5; 95 % cI=11.6–1643.1; p=0.001), the presence of an electric cardiac pacemaker in the patient (OR, 31.71; 95 % cI=2.69–373.84; p=0.05), and need for IcA resection (OR, 6.83; 95 % cI=2.1–21.48; p=0.004). The risk factor for contralateral stroke in the early postoperative period was the use of a temporary intraluminal shunt (OR – 35.86; 95 % cI=2.17–592.92; p=0.05). Tortuosity of the target artery (OR – 4.6; 95 % cI=1.1–18.3; p=0.017), the need for IcA resection and in the presence of complicated atherosclerotic plaque in the reconstruction area (OR – 6.84; 95 % cI=1.89–24.85; p=0.01) turned out to be the sig nificant risk of death in the immediate postoperative period.CONCLUSIONS. Significant risk factors for recurrent stroke and death after carotid endarterectomy performed in the acute period of stroke were the tortuosity of the target artery, an aneurysm in the tortuosity zone, the presence of an electric cardiac pacemaker in the patient and the need for IcA resection in the presence of complicated atherosclerotic plaque in the reconstruction zone. The only risk factor for contralateral stroke in the early postoperative period was the use of a temporary intraluminal shunt. Further large trials are needed to clarify the obtained results.

SINGLE CENTER EXPERIENCE IN SURGICAL TREATMENT FOR ACTIVE ENDOCARDITIS BEFORE AND AFTER COVID–19 PANDEMIC

Abstract Background Despite advanced diagnosis and treatment, infective endocarditis (IE) is a potentially life–threatening condition. The impact of COVID–19 on diagnosis and outcome of surgical treatment of IE is uncertain. The aim of this study was to analyze the incidence, characteristics and outcomes of surgically treated IE before and after the COVID–19 pandemic. Methods This study retrospectively analyzed data of 536 patients who underwent valve surgical procedures for IE between January 2010 and December 2022 in a single cardiac surgery center. Patients were divided in two groups depending on the date of operation: before (n=393) and after (n=142) COVID–19 onset. In order to balance the groups, inverse probability of treatment weighting (IPTW) calculated from the propensity score (PS) was applied. Results We noticed a significant increase (p=0.006) in the prevalence of infective endocarditis admitted for surgery throughout the years, comparing it to overall hospitalizations in our cardiac surgery department (Figure 1). Patients from the post COVID cohort (after march 2020) had more comorbidities such as diabetes (29.6% vs 16.3% p=0.001), hypertension (71.1% vs 59.5% p=0.015), and preoperative kidney injury requiring dialysis (9.2% vs 2.5% p=0.002), but median additive and logistic Euroscore were not statistically different. In the post COVID group, we observed a greater prevalence of S. Aureus related endocarditis (24.5% vs 15.4% p=0.026), and a consequent reduction in S. non Aureus related endocarditis (12.2% vs 20.1% p=0.048) (Figure 2), a decrease of aortic valve replacement (43.0% vs 53.9%), while the number of mitral valve replacement ad repair resulted to be higher (21.1% vs 15.0% and 6.3% vs 4.3% respectively) (Figure 3). No differences in the two groups concerning early death but also death or relapse at one year after surgery. Data obtained by the multivariable analysis identify the preoperative renal dysfunction requiring dialysis as the only common risk factor for early mortality stratifying by time periods in analysis. Conclusions The incidence of surgical treated IE significant increase after COVID–19 pandemic with a higher incidence of mitral involvement instead of aortic valve. Despite the pandemic and the delay in surgical timing, results in terms of mortality and outcomes have improved and were largely unaffected by the COVID–19 pandemic.

Displaced proximal humeral fractures in skeletally immature patients: functional outcomes of surgical treatment.

To report the functional results of our experience and to describe intraoperative findings and complications due to the techniques used in our service. From January 2018 to December 2022, 27 Pediatric patients aged from 8 to 16years underwent surgery to treat proximal humerus fractures. Their demographic characteristics were evaluated, as well as their clinical characteristics on admission, type of reduction (closed/open), presence of interposition in open reductions, type of implant, complications, and functional range of movement according to two shoulder functional scores. Mean age was 11.2years (8-15), there was a predominance of males, who accounted for 70% of the cases, and sports accidents were the cause of injury in 44% of the cases. Anatomical location was balanced between patients, including 55% of physeal fractures and 45% of metaphyseal ones. Overall, 81.5% of patients required open reduction to achieve axis correction, and that 55.5% of fractures were fixed with Kirschner wires, and 44, 4% with elastic titanium nails. Mean QuickDASH score was 0.58 (0-1.7), and Constant score was 9 (3-24). There were no major complications, but 27% of cases subjected to open reduction presented a hypertrophic scar. Surgical treatment of severely displaced proximal humerus fractures is successful, both with closed and open reduction; type of implant does not play a key role and should be selected based on the characteristics of each case. Surgical training should prevail at the time of decision-making. When these recommendations are followed, results can be excellent and sequelae are infrequent.
