Influencing factors for surgical treatment in neonatal necrotizing enterocolitis: a systematic review and meta-analysis

BackgroundNecrotizing enterocolitis (NEC) is a complex disease characterized by gastrointestinal inflammation and is one of the most common gastrointestinal emergencies in neonates. Mild to moderate cases of NEC require medical treatment, whereas severe cases necessitate surgical intervention. However, evidence for surgical indications is limited and largely dependent on the surgeon’s experience, leading to variability in outcomes. The primary aim of this study is to identify the risk factors for surgical intervention in neonatal NEC, which will aid in predicting the optimal timing for surgical intervention.MethodsA literature search was conducted in PubMed, Embase, and Web of Science databases for case-control studies exploring risk factors for NEC requiring surgical intervention. The search was completed on June 16, 2024, and data analysis was performed using R Studio 4.3.2.Results18 studies were included, comprising 1,104 cases in the surgery group and 1,686 in the medical treatment group. The meta-analysis indicated that high C-reactive protein (CRP) levels [OR = 1.42, 95% CI (1.01, 1.99)], lower gestational age [OR = 0.52, 95% CI (0.3, 0.91)], sepsis [OR = 2.94, 95% CI (1.87, 4.60)], coagulation disorder [OR = 3.45, 95% CI (1.81, 6.58)], lack of enteral feeding [OR = 3.18, 95% CI (1.37, 7.35)], and hyponatremia [OR = 1.22, 95% CI (1.07, 1.39)] are significant risk factors for surgical treatment in neonatal NEC.ConclusionsHigh CRP levels, coagulation disorders, sepsis, lower gestational age, lack of enteral feeding, and hyponatremia are significant risk factors for surgical intervention in neonatal NEC. These findings have potential clinical significance for predicting surgical risk.

Surgical Interventions Following Radiotherapy in Spinal Metastases with Intermediate Instability: A Risk Factor Analysis: The Korean Society of Spinal Tumor Multicenter Study (KSST 2022-02).

One important determinant in choosing a treatment modality is spinal instability. Clear management guidelines are suggested for stable and unstable spinal metastatic lesions, but lesions in the intermediate instability category (SINS [spinal instability neoplastic score] score of 7-12) remain a clinical dilemma. This study aims to analyze the risk factors necessitating surgical intervention after radiotherapy (RT) in patients with those lesions. A multicenter cohort of 469 patients with spinal metastases of intermediate instability who received radiotherapy (RT) as the initial treatment between 2019 and 2021 were retrospectively enrolled. All patients were neurologically intact at the time of RT. According to the performance of surgical intervention after RT, various clinical and radiographic risk factors for surgical intervention were compared between surgery and non-surgery groups using uni- and multivariate analyses. A recursive partitioning analysis (RPA) was performed using significant determinants identified in multivariate analysis. The mean age at the time of RT was 59.9 years and there were 198 females. The lung was the most common primary site. During the mean follow-up duration of 18.2 months, surgical treatment was required in 79 (17.9%) of patients. The most common surgical method was decompressive laminectomy with stabilization (62.0%), followed by vertebrectomy with stabilization (22.8%) and stabilization only (15.2%). The mean SINS for the total cohort was 9.0. Multivariate regression analyses revealed that the primary tumor site of the lung, liver, and kidney, higher Bilsky grades of ESCC, lytic bone lesions, and higher EQD210 were significant risk factors for surgical intervention after RT. Among them, Bilsky grade, primary tumor type of the lung, liver, and kidney, and EQD210 were the most important determinants for expecting the probability of surgical intervention on RPA. Surgical intervention was performed in 17.9% of patients with intermediate instability after RT as the initial treatment. The primary tumor site of the lung, liver, and kidney, higher Bilsky grade of ESCC, and EQD210 were the most important determinants for expecting the probability of surgical intervention. Therefore, the optimal treatment strategy needs to be devised by carefully evaluating the risk of surgical intervention.

Surgery for carpal tunnel syndrome in patients with and without diabetes-Is there a difference in the frequency of surgical procedures?

Carpal tunnel syndrome (CTS) occurs more often among individuals with diabetes. The aim of this retrospective observational registry study was to examine whether individuals with diabetes and CTS are treated surgically to the same extent as individuals with CTS but without diabetes. Data on CTS diagnosis and surgery were collected from the Skåne Healthcare Register (SHR). A total of 35,105 individuals (age ≥ 18 years) diagnosed with CTS from 2004-2019 were included. Data were matched to the Swedish National Diabetes Register (NDR. Cox regression models were used to calculate the risk of the use of surgical treatment. Of the 35,105 included individuals with a CTS diagnosis, 17,662 (50%) were treated surgically, and 4,966 (14%) had diabetes. A higher number of individuals with diabetes were treated surgically (2,935/4,966, 59%) than individuals without diabetes (14,727/30,139, 49%). In the Cox regression model, diabetes remained a significant risk factor for surgical treatment (PR 1.14 (95% CI 1.11-1.17)). Individuals with type 1 diabetes were more frequently treated surgically (490/757, 65%) than individuals with type 2 diabetes (2,445/4,209, 58%). There was no difference between the sexes and their treatment. The duration of diabetes was also a risk factor for surgical treatment in diabetes type 2, but high HbA1c levels were not. Individuals with diabetes are more likely to be treated surgically for CTS than individuals without diabetes. Individuals with type 1 diabetes are more likely to be treated surgically for CTS than individuals with type 2 diabetes.

Risk Factors for Surgical Treatment of Lumbar Degenerative Disc Disease in Middle-aged and Older Women: A Prospective Case-Control Study of 2370 Subjects.

Given the distinct physiological and societal traits between women and men, we propose that there are distinct risk factors for lumbar degenerative disc disease surgeries, including lumbar disc herniation (LDH) and lumbar spinal stenosis (LSS), in middle-aged and older populations. However, few studies have focused on middle-aged and older women. This study aims to identify these risk factors specifically in this population. In this case-control study, the study group comprised 1202 women aged ≥ 45 years who underwent operative treatment of lumbar degenerative disc disease (LDH, n = 825; LSS, n = 377), and the control group comprised 1168 women without lumbar disease who visited a health examination clinic during the same period. The study factors included demographics (age, body mass index [BMI], smoking, labor intensity, and genetic history), female-specific factors (menopausal status, number of deliveries, cesarean section, and simple hysterectomy), surgical history (number of abdominal surgeries, hip joint surgery, knee joint surgery, and thyroidectomy), and systemic diseases (hypercholesterolemia, hypertriglyceridemia, hyper-low-density lipoprotein cholesterolemia, hypertension, diabetes, cardiovascular disease, and cerebrovascular disease). Multivariate binary logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (95% CI) of associated factors. The risk factors for surgical treatment of LDH in middle-aged and older women included BMI (OR = 1.603), labor intensity (OR = 1.189), genetic history (OR = 2.212), number of deliveries (OR = 1.736), simple hysterectomy (OR = 2.511), hypertriglyceridemia (OR = 1.932), and hyper-low-density lipoprotein cholesterolemia (OR = 2.662). For surgical treatment of LSS, the risk factors were age (OR = 1.889), BMI (OR = 1.671), genetic history (OR = 2.134), number of deliveries (OR = 2.962), simple hysterectomy (OR = 1.968), knee joint surgery (OR = 2.527), hypertriglyceridemia (OR = 1.476), hyper-low-density lipoprotein cholesterolemia (OR = 2.413), and diabetes (OR = 1.643). Cerebrovascular disease was a protective factor against surgery for LDH (OR = 0.267). BMI, genetic history, number of deliveries, simple hysterectomy, hypertriglyceridemia, and hyper-low-density lipoprotein cholesterolemia were independent risk factors for surgical treatment of both LDH and LSS in middle-aged and older women. Two disparities were found: labor intensity was a risk factor for LDH patients, and knee joint surgery and diabetes were risk factors for LSS patients.

Emergency department utilisation and treatment for trauma-related presentations of adolescents aged 16–18: a retrospective cross-sectional study

BackgroundA recent study conducted at our tertiary hospital emergency department (ED) reviewed ED consultations and found that adolescents aged 16–18 years present significantly more often for trauma and psychiatric problems than adults over 18 years. Accidental injuries are one of the greatest health risks for children and adolescents. In view of the increased vulnerability of the adolescent population, this study aimed to further analyse trauma-related presentations in adolescents.MethodsWe conducted a single-centre, retrospective, cross-sectional study of all adolescent trauma patients aged 16 to 18 years presenting to the adult ED at the University Hospital (Inselspital) in Bern, Switzerland, from January 2013 to July 2017. We analysed presentation data as well as inpatient treatment and cost-related data. Data of female and male patients were compared by univariable analysis. A comparison group was formed consisting of 200 randomly chosen patients aged 19–25 years old with the same presentation characteristics. Predictive factors for surgical treatment were obtained by multivariable analysis.ResultsThe study population included a total of 1,626 adolescent patients aged 16–18 years. The predominant causes for ED presentation were consistent within case and comparison groups for sex and age and were sports accidents, falls and violence. Male patients were more likely to need surgical treatment (OR 1.8 [95% CI: 1.2–2.5], p = 0.001) and consequently inpatient treatment (OR 1.5 [95% CI: 1.1–2.1], p = 0.01), associated with higher costs (median 792 Swiss francs [IQR: 491-1,598]). Other independent risk factors for surgical treatment were violence-related visits (OR 2.1 [95% CI: 1.3–3.5, p = 0.004]) and trauma to the upper extremities (OR 2.02 [95% CI: 1.5–2.8], p < 0.001). Night shift (OR 0.56 [95% CI: 0.37–0.86], 0.008) and walk-in consultations (OR 0.3 [95% CI: 0.2; 0.4, < 0.001] were preventive factors for surgical treatment.ConclusionsMale adolescents account for the majority of emergency visits and appear to be at higher risk for accidents as well as for surgical treatment and/or inpatient admission due to sports accidents or injuries from violence. We suggest that further preventive measures and recommendations should be implemented and that these should focus on sport activities and injuries from violence.

Impact of lifestyle and clinical factors on the prognosis of tennis elbow

Tennis elbow (lateral epicondylitis) typically responds well to conservative treatment, and few patients require surgical intervention. This study aimed to investigate the influence of lifestyle and clinical factors on the prognosis of tennis elbow. This prospective, multicenter, nested case–control study included patients diagnosed with lateral epicondylitis after excluding other conditions. Patients who required surgery because of inadequate improvement after 6 months of conservative treatment were defined as the case group; the remaining patients constituted the control group. Propensity score matching was performed to eliminate baseline differences. Univariate and multivariate analyses were performed using logistic regression. This study included 265 patients (53 in the case group, 212 in the control group). Multivariate analysis revealed that smoking, alcohol consumption, and frequent physical exercise were independent risk factors for surgical intervention, whereas combined treatment with oral nonsteroidal anti-inflammatory drugs (NSAIDs) and local corticosteroid injections was a protective factor against surgery. Subgroup analysis showed that heavy drinkers had a 3.74-fold higher risk of requiring surgical treatment within 1 year than occasional drinkers. Smoking and alcohol consumption were associated with non-operative treatment failure in patients with lateral epicondylitis. Combining oral NSAIDs and corticosteroid injections is a favorable conservative treatment option.

Intracranial Arachnoid Cyst in Children: Clinical Presentation and Risk Factors for Surgical Intervention

Plain Language SummaryPediatric imaging findings of brain cysts are a common finding. Some cysts do not require surgical intervention while others may require surgery. We conducted a retrospective chart review from 2009 to 2021 on patients aged 0–21 years of age who were found to have a brain cyst on imaging reports. Our aim was to identify clinical risk factors in patients with brain cysts who underwent surgery versus those who did not. A total of 230 patients were included in the study, of which 45 (19.6%) underwent surgery. Overall, surgical patients were younger (median age 1.1 years) and had a median cyst volume larger (41.7 cm3), compared to nonsurgical patients (median age 5.9 years, volume 11.8 cm3, respectively). The most common reason to undergo initial imaging was headache for nonsurgical patients (54/185, 29.2%) while surgical patients had initial imaging due to large head size (11/45, 24.4%) or imaging carried out prenatally to 1 year of life (11/45, 24.4%). We found that cyst volume and age at diagnosis were predictors for surgical intervention. The greater the cyst volume was at initial diagnosis and the younger the patient was at time of diagnosis, the greater the odds the patient had of undergoing surgical intervention. Therefore these patients should be monitored closely for development of symptoms indicating a need for surgical intervention.

Analysis of Risk Factors for Surgical Treatment of Acute Female Pelvic Inflammatory Disease.

To investigate the incidence and high-risk factors associated with the surgical treatment of acute female pelvic inflammatory disease (PID). A retrospective analysis was conducted on all inpatients diagnosed with acute female PID, encompassing conditions such as endometritis, salpingitis, tubo-ovarian abscess, ovarian abscess, and pelvic peritonitis, at Dongyang Hospital of Wenzhou Medical University from January 2013 to December 2021. Patients were categorized into two groups: the surgery group (n = 58) and the non-surgery group (n = 399), based on the necessity of surgical intervention (refer to Materials and Methods for surgical indications). Collected data included patient demographics (age, body mass index (BMI)), comorbidities (hypertension, diabetes mellitus), initial laboratory findings upon admission (white blood cell count, absolute neutrophil count, hemoglobin, platelet count, blood urea nitrogen/creatinine, prothrombin time (PT), international normalized ratio (INR), fibrinogen, albumin), surgical records, and postoperative pathology. Univariate and multivariate logistic regression analyses were conducted to ascertain the risk factors associated with the surgical treatment of acute female PID. Out of 457 hospitalized patients with acute female PID, 58 cases (12.7%) required surgical intervention. Univariate and multivariate logistic regression analyses indicated that advancing age correlated with an increased likelihood of surgical intervention in women with acute PID (odds ratio (OR) = 1.052, 95% Confidence Interval (CI) 1.022-1.082, p = 0.001). Additionally, lower serum albumin levels upon admission were associated with a heightened risk of surgery (OR = 0.913, 95% CI 0.859-0.970, p = 0.003), while elevated fibrinogen levels amplified the risk of surgical intervention in these patients (OR = 1.193, 95% CI 1.008-1.411, p = 0.04). Elderly women diagnosed with acute PID, especially those presenting with abscess formation, should undergo prompt surgical intervention if they display high-risk factors such as low albumin levels and elevated fibrinogen levels upon admission.

Gluteal Muscle Fatty Atrophy: An Independent Risk Factor for Surgical Treatment in Elderly Patients Diagnosed with Type-III Fragility Fractures of the Pelvis.

Gluteal muscle fatty atrophy (gMFA) might impair pelvic stability and negatively influence remobilization in patients with fragility fractures of the pelvis (FFP). This study aimed to investigate the association between gMFA and surgical indication in patients with FFP. A retrospective analysis of 429 patients (age ≥80) diagnosed with FFP was performed. gMFA of the gluteus maximus, medius, and minimus was evaluated using a standard scoring system based on computer tomography images. No significant difference was found in gMFA between genders or among FFP types. The severity of gMFA did not correlate with age. The severity of gMFA in the gluteus medius was significantly greater than in the gluteus maximus, whereas the most profound gMFA was found in the gluteus minimus. gMFA was significantly more severe in patients who underwent an operation than in conservatively treated patients with type-III FFP, and an independent correlation to surgical indication was found using logistic regression. Our findings imply that gMFA is an independent factor for surgical treatment in patients with type-III FFP. Besides focusing on the fracture pattern, the further evaluation of gMFA could be a feasible parameter for decision making toward either conservative or surgical treatment of type-III FFP.

Clinical comparative analysis of culture-proven bacterial keratitis according to prior topical steroid use: a retrospective study in a tertiary referral center of South Korea

This study analyzed the clinical characteristics of patients exposed to topical steroids before bacterial keratitis diagnosis (the prior topical steroid use, PS group), and compared these with those of the non-exposed group (the no prior topical steroid use, NPS group). We retrospectively analyzed 194 patients (PS, 34; NPS, 160) with culture-proven bacterial keratitis between 2007 and 2016. The microbiological profiles, epidemiology, predisposing factors, clinical characteristics, and treatment outcomes of PS and NPS were compared, and the risk factors for surgical intervention were evaluated. Pseudomonas spp. and Staphylococcus spp. were the most common isolates in PS and NPS, respectively, and no significant difference in the strain distribution between the two groups were observed. Significant differences were observed between PS and NPS for previous ocular surface disease (41.2%: 23.8%), initial BCVA < 0.1 (70.6%: 49.4%), epithelial defect size ≥ 5 mm2 (64.7%: 41.2%), epithelial healing time > 14 days (55.9%: 37.3%), and surgical intervention (23.5%: 8.8%). Prior topical steroid use, strong steroid use, and long-term steroid use groups were included in significant risk factors for surgical intervention. Previous exposure to topical steroids before the diagnosis of bacterial keratitis was associated with a worse initial clinical presentation and treatment outcomes. Additional multicenter studies should be conducted in the future.

High survival rate after the combination of intrameniscal and intraarticular infiltrations of platelet-rich plasma as conservative treatment for meniscal lesions.

To evaluate the efficacy of applying a combination of intrameniscal and intraarticular infiltrations of Platelet-Rich Plasma (PRP) in patients with meniscal tears, analyzing its failure rate and clinical evolution, as well as factors that may influence the positive response to this treatment. Three hundred and ninety-two cases out of 696 met the inclusion criteria and were included in this work. Survival and patient-reported outcome measure (PROM) were collected and analyzed. Survival rate was defined as the percentage of patients who did not undergo meniscus surgery during their follow-up time. Patients were asked to complete the Knee injury and Osteoarthritis Outcome Score (KOOS) at baseline, 6months and 18months. Other patient- and pathology-related variables were collected. Blood and PRP samples were randomly tested as a quality control measure. Survival and comparative statistical tests, and multivariate regression were performed for the analysis of the variables. The PRP applied had a platelet concentration factor of 1.9X in respect to blood levels, with no leukocytes or erythrocytes. Thirty-eight patients required surgical intervention after treatment reaching a survival rate of 90.3% with an estimated mean survival time of 54.4months. The type of injury (P = 0.002) and the presence of chondropathy were risk factors for surgical intervention after PRP treatment (P = 0.043). All KOOS scores showed a significant statistical increase from baseline to 6months (N = 93) and 18months (N = 66) (P < 0.0001). The number of cases with minimal clinically important improvement (MCII) at 6months and 18months post-treatment was 65 (69.9%) and 43 (65.2%), respectively. The combination of intrameniscal and intraarticular PRP infiltrations is a valid conservative treatment for meniscal injuries avoiding the need for surgical intervention. Its efficacy is higher in horizontal tears and decreases when joint degeneration is present. Level IV.

Risk Factors for Chalazion Diagnosis and Subsequent Surgical Excision

ABSTRACT Purpose To identify factors associated with chalazion diagnosis and surgical excision. Methods Patients with an incident chalazion diagnosis from 2002 to 2019 were compared 1:5 with matched controls. Multivariable logistic regression was performed to identify variables associated with diagnosis and surgical excision. Results Chalazion patients (n = 134,959) and controls (678,160) were analyzed. Risk factors for diagnosis included female sex, non-white race, northeast location, conditions affecting periocular skin and tear film (blepharitis, meibomian gland dysfunction, rosacea, pterygium), non-ocular inflammatory conditions (gastritis, inflammatory bowel disease, sarcoidosis, seborrheic dermatitis, Graves’ disease), and smoking (p < .001 for all comparisons). Thirteen percent of patients with chalazion underwent subsequent surgical excision. Diabetes and systemic sclerosis diagnoses decreased odds of diagnosis (p < .001). Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use increased odds of surgery (p < .001). Conclusion Female sex, non-white race, conditions affecting periocular skin and the tear film, several non-ocular inflammatory conditions, and smoking were risk factors for chalazion diagnosis. Male sex, rosacea diagnosis, Black and Hispanic race, antibiotic use, and doxycycline use were risk factors for surgical intervention for chalazion. Our results prompt further study of these variables and their relationship to chalazion diagnosis to understand physiology and improve clinical outcomes. Furthermore, the results of this study suggest early recognition and treatment of concomitant rosacea may serve an important role in the management of chalazion and in the prevention of surgical intervention.

Choroidal Effusions after Glaucoma Drainage Implant Surgery: Risk Factors and Surgical Management

To report the incidence of patients who developed choroidal effusions after glaucoma drainage implant (GDI) surgery and determine risk factors for and outcomes of surgical intervention. Retrospective case series. Medical records of 605 patients who underwent GDI surgery from January 1, 2017 to June 7, 2021 at New York University Langone Health and New York Eye and Ear Infirmary of Mount Sinai were reviewed. Preoperative, intraoperative, and postoperative clinical data were obtained. Multivariate logistic regression evaluated the factors associated with the need for surgical intervention. Patient records were analyzed for effusion resolution, intraocular pressure (IOP), visual acuity (VA), and complications across treatment modalities. Incidence of choroidal effusion development and need for surgical intervention. Choroidal effusions developed in 110 (18%) patients (110 eyes). Surgical intervention to drain the effusion or ligate the implant tube was performed in 19 (17%) patients. The average time to surgical intervention was 47.6 days. Among patients who developed postoperative effusions, risk factors for requiring surgical intervention included history of selective laser trabeculoplasty (SLT) (P=0.004; odds ratio [OR], 14.4), prior GDI surgery (P=0.04; OR 8.7), 350-mm2 Baerveldt glaucoma implant placement (P=0.05; OR, 4.8), and anterior chamber shallowing (AC; P<0.001; OR, 25.1) in the presence of effusions. The subgroup that required multiple surgeries for effusion resolution had a significantly lower mean IOP at the most recent follow-up compared with those who received medical management only (P<0.001). A higher percentage of patients who required surgical intervention lost VA at the most recent follow-up compared with patients whose effusions resolved with conservative management (i.e., medical management, AC viscoelastic injection). Choroidal effusions after GDI surgery resolved with conservative management in most patients. A history of SLT or GDI placement, implantation of a BGI-350, and the presence of a shallow chamber were risk factors for surgical intervention. Although interventions, such as surgical drainage are at times necessary, a better understanding of their impacts can help guide postoperative decisions. The risks and benefits of these procedures must be carefully considered in these high-risk eyes. Proprietary or commercial disclosure may be found after the references.

Independent reliability and availability analyses of modified classification for migrated lumbar disc herniation

Study designRetrospective cohort study.ObjectiveThe purpose of this study was to evaluate the reliability of modified classification system of migrated nucleus pulposus and its clinical application value.MethodsWe retrieved 1000 lumbar MRI of different patients in Hangzhou Hospital of Traditional Chinese Medicine from January 2016 to December 2019 for interpretation, and screened 105 migrated lumbar MRI for inclusion in the study. Three spinal surgeons made classification according to the modified classification method. Two weeks later, the sorting data of the patients were shuffled and the classification was judged by three doctors again. The consistency and repeatability of the improved classification were evaluated by Kappa coefficient. The general data of the included patients were collected. The patients were followed up for 2 years, and the risk factors of surgical treatment of patients with migrated lumbar disc herniation were analyzed. The treatment plan, surgical approach, operation time, VAS score, ODI score and other relevant data of the included patients were collected to evaluate the guiding effect of the classification system on clinical practice.ResultsIn this study, the incidence of migrated lumbar disc herniation was about 10.5%, and most of the patients were male. Patients with higher BMI are more likely to develop this disease. Our study confirmed that the modified classification has moderate to high confidence. During the 2-year follow-up period, 66 patients (62.9%) were treated conservatively, and the patients with conservative treatment were mainly A2 and B2 type (59.1%). Thirty-nine patients (37.1%) underwent surgical treatment. The patients recovered well after operation, and the low back pain and ODI index were significantly improved at 1 year after operation (P < 0.05). We suggest that type A1 and B1 migrated nucleus pulposus can be removed by posterior approach. For type A2, B2, C1, C2, the lateral approach is recommended to remove the nucleus pulposus directly. Logistic regression and ROC analysis showed that disease duration (≥ 1 year) and BMI (≥ 24) maybe were risk factors for surgical treatment of patients with migrated lumbar disc herniation.ConclusionThe modified classification has good reliability. In the current study, the experience level of spine surgeons does not affect the reliability of the classification system. Our study confirmed that this classification has a good reference value for guiding the treatment plan and the choice of surgical approach.

Analysis of the efficacy and risk factors of surgical treatment of recurrent UPJO in adults

BackgroundTo compare the efficacy of secondary pyeloplasty and balloon dilation and to analyze the risk factors for secondary surgical failure in patients with recurrent uretero-pelvic junction obstruction (UPJO).MethodsWe retrospectively analyzed 65 patients with recurrent UPJO who underwent secondary surgery between September 2011 and March 2019, of whom 33 had complete baseline data and follow-up data. General clinical information, perioperative data, and follow-up results were collected from patients. Risk factors for surgical failure in patients with recurrent UPJO were analyzed using logistic regression.ResultsThe failure rates of secondary pyeloplasty and balloon dilation in secondary surgery were 16.7% and 33.3%, respectively. Univariate analysis showed that ureteral stenosis length and operative time were associated with secondary pyeloplasty and balloon dilatation failure (p < 0.05), and ureteral stenosis length was an independent risk factor for secondary pyeloplasty failure (OR = 0.074, 95% CI: 0.006–0.864, p = 0.038). In the balloon dilation group, treatment failure rates were significantly lower in patients with stenotic segment lengths less than 1 ± 0.32 cm than in patients with stenotic segment lengths greater than 1 ± 0.32 cm (p = 0.019).ConclusionsThe secondary pyeloplasty may provide better benefit. Ureteral stricture length is an independent risk factor for failure of secondary pyeloplasty and a potential risk factor for balloon dilatation. Operation time is a potential risk factor for pyeloplasty and balloon dilatation.

Efficacy of Anterior Cervical Discectomy and Fusion for Female Patients with Hirayama Disease

To compare the preoperative and postoperative hand function and radiographic parameters in female patients with HD. Consecutive female patients with HD undergoing anterior cervical discectomy and fusion were followed-up. The postoperative hand functional data were obtained from the last follow-up, while the postoperative radiographic data were obtained from the examinations in 3- or 6-month follow-up after surgical treatments. The preoperative and postoperative data of hand functional and radiographic assessments were collected and compared between them. Logistic regression analysis was used to clear potential risk factors for surgical treatment. In all, 15 female patients with HD were included in the follow-up study over 9 years. Significant differences were found in total scores (P<0.001) and all five dimensions, including function (P=0.003), activities of daily life (P=0.002), work (P=0.003), satisfaction (P=0.002), appearance (P=0.005), and HD-specific hand symptoms (P=0.001) in hand functional assessment. The comparison of C2-7 Cobb angle was statistically different (P=0.042) in radiographic assessments. The course of illness was of marginal significance (P=0.065) with curative effect of surgical treatment in logistic regression analysis. Anterior cervical discectomy and fusion was an effective way to treat female patients with HD, and the course of illness may be correlated with the efficacy of surgery. For some female patients with HD with a clear diagnosis, early surgical treatment is worthy of clinical consideration.

Predictors of surgical intervention in the onset of stenotic Crohn’s disease in a 15-year-old teenager

Aim: to demonstrate a child with early ileocecal resection in stenosing Crohn’s disease, taking into account the risk factors of surgical intervention. Crohn’s disease (CD) is a chronic recurrent segmental granulomatous lesion of any part of the gastrointestinal tract, with a wide range of manifestations and various phenotypes of the disease. Despite the great diagnostic and therapeutic possibilities today, there is an increase in primary and secondary resistance to therapy, largely associated with an incorrect assessment of the CD phenotype, patient management strategy. In the above observation of CD in a teenager, clinical signs of ileocecal stenosis were observed 3 months after the supposed onset of the disease, which caused a planned laparoscopic ileocecal resection with the formation of a ileo-colon anastomosis. The start of CD in adolescence, positive ASCA-status are regarded as risk factors for surgical intervention in this child. Timely diagnosis did not allow to avoid surgery. It is necessary to make individual algorithms for the management of a child with CD, taking into account the predictors of surgical intervention, complications and unfavorable course of the disease already at the time of diagnosis.

Surgical treatment of tumors of the supplementary motor area

Background. The supplementary motor area is a part of the medial frontal cortex, that is located just anterior to the primary motor cortex entirely within the interhemispheric fissure. This area belongs traditionally to the secondary motor cortex and perhaps it is the least studied motor region of the brain. While functions and symptoms of a damage to the primary motor and the premotor cortex areas have been well known and described for a long time, study of the supplementary motor area has been limited to fundamental neuroimaging and electrophysiological researches, and a practical side of the issue and clinical significance of this region remained outside the interest of researchers.Aim. To present the anatomical and functional features of the supplementary motor area, the clinical symptoms of its lesion, to analyze all the data available today and aspects of surgical treatment of tumors in this region.Materials and methods. A search in scientific databases (PubMed, etc.) led to the selection and analysis of sixty-two literary sources. The review is mainly devoted to the aspects and risk factors of surgical treatment of pathologies localized in this region.Results. According to its anatomical and functional characteristics, the supplementary motor area is a heterogeneous region - it has two separate subregions in it. In addition to the motor function of the supplementary motor area, its role has also been reliably established in the implementation of working memory processes, language, perceptual, cognitive and other functions. Such a number of functions performed by the supplementary motor area is associated with numerous neural connections of this area. For example, the frontal aslant tract has been described recently, and it connects medial part of the superior frontal gyrus with the pars opercularis of the inferior frontal gyrus. This tract, apparently, is associated with the implementation of language function in the dominant hemisphere and function of working memory in the non-dominant hemisphere.When the supplementary motor area is affected, various neurological motor and speech symptoms can occur, in particular, the supplementary motor area syndrome, which is characterized by the development of akinetic mutism in patients and, in most cases, is completely reversible within a few days or months. Among all pathologies in this area, tumors are most common, especially gliomas, which can also manifest themselves with various clinical symptoms both in the preoperative and postoperative periods.Conclusion. Critically important preoperative planning, informing the patient about the spatio-temporal picture of the predicted postoperative clinical disorders and the timing of rehabilitation are critically important. It is recommended to use methods of intraoperative neuronavigation, as well as intraoperative neurophysiological monitoring. It is necessary to further study the supplementary motor area and the peculiarities of its surgery in order to standardize approaches to the treatment of pathologies.

Anteroinferior Glenoid Rim Fractures Are a Relatively Common Finding in Shoulder Instability Patients Aged 50 Years or Older but May Not Portend a Worse Prognosis

PurposeTo investigate the incidence of anteroinferior glenoid rim fractures (AGRFs) after anterior shoulder instability (ASI) in patients aged 50 years or older, identify risk factors for surgical intervention for AGRFs, compare initial treatment strategies, and compare clinical outcomes of patients with and without associated AGRFs.MethodsAn established geographic medical record system was used to identify patients aged 50 years or older with ASI between 1994 and 2016. Patients with radiographic evidence of AGRFs were identified and matched 1:1 to patients without AGRFs. Outcome measures included recurrent instability, recurrent pain events, conversion to arthroplasty, and osteoarthritis graded with the Samilson-Prieto classification for post-instability arthritis.ResultsOverall, 177 patients were identified, with a mean follow-up period of 10.8 years. Of these patients, 41 (23.2%) had AGRFs and were matched to 41 control patients without AGRFs. The average age was 58.6 and 58.2 years for the AGRF and control groups, respectively. Rates of surgical intervention (27% vs 49%), recurrent instability (12% vs 20%), progression of osteoarthritis (34% vs 39%), and conversion to arthroplasty (2% vs 5%) were similar between AGRF patients and controls. For patients with AGRFs, increased bone fragment size (odds ratio, 1.1) and increased body mass index (odds ratio, 1.2) correlated with an increased risk of surgery. The cutoff value for an increased risk of surgery in patients with AGRFs was a fragment size 33% of the glenoid width or greater.ConclusionsOf patients aged 50 years or older at presentation of ASI, 23.2% presented with an associated AGRF. A fragment size 33% of the glenoid width or greater and a higher patient body mass index were significant factors for surgical intervention; however, most patients did not require surgery and still showed acceptable clinical outcomes, and the most common reason for surgical intervention was a rotator cuff tear. Overall, the presence of an AGRF did not portend a worse prognosis as treatment strategies and long-term outcomes including recurrent instability, progression of osteoarthritis, and conversion to arthroplasty were similar to those in patients without AGRFs.Level of EvidenceLevel III, retrospective comparative study.
