While subject-specific modeling poses challenges, emerging software tools enable rapid personalization of musculoskeletal geometry and motor control, enhancing physiological accuracy. Advanced predictive simulations and multi-scale modeling expand clinical applications, facilitating surgery outcomes prediction and movement modification for joint diseases. Collaborative interdisciplinary efforts are essential for overcoming challenges, refining workflows, and ultimately enhancing clinical treatment outcomes.

A systematic review and meta-analysis of long-term outcomes of femoral derotation surgery for intoeing gait in cerebral palsy

BackgroundFemoral derotation osteotomy is treatment of choice in intoeing gait secondary to cerebral palsy (CP). Research questionThe aim of this study was to critically appraise the literature regarding the long-term outcomes of femoral derotation surgery in CP. MethodsElectronic databases of PubMed and Scopus was used for the literature review by two researchers independently (SB, SC). The study population included patients of cerebral palsy undergoing femoral derotation surgery. The keywords used were “cerebral palsy”, “intoeing gait”, “femur anteversion”, “hip anteversion”, “femur derotation” and “femur osteotomy”. ResultsNine studies which included 657 limbs in 407 patients were selected for this study of which eight were retrospective in nature. The improvement in hip rotation at stance at last follow up (more than five years) maintained a statistical significance (SMD 1.67 95 %CI 1.12–2.22). Similar statistically significant outcomes were noted for foot progression angle (SMD 1.19 95 %CI 0.92–1.47), anteversion (SMD 2.75 95 %CI 1.49–4.01) and total passive internal rotation (SMD 1.71 95 %CI 1.19–2.22). SignificanceFemoral derotation surgery is the procedure of choice for correction of intoeing gait in CP. Even though, there is deterioration of results on long-term as compared to short term, majority of the patients shall maintain overall correction without recurrence of an intoeing gait. Future studies with uniform criteria for defining recurrence on the basis of functional limitations shall provide better idea about the natural course of this procedure.

Does Surgical Robot Know What It’s Doing? Understanding Patient Fear and Anxiety

Robot-assisted surgery (RAS) is a fast-emerging area of medicine that offers numerous benefits compared to conventional open surgery. Nevertheless, certain patients may encounter fear and anxiety over robot-assisted surgery as a result of several circumstances. This study sought to examine the underlying factors contributing to fear and anxiety in patients who underwent robot-assisted surgery and to propose implications to alleviate such emotions. The study used a qualitative research design, collecting data via 25 semi-structured interviews with individuals who have undergone RAS for various ailments. The interviews were transcribed and examined using text analysis techniques. The primary factors contributing to fear and anxiety encompass a lack of knowledge and understanding regarding RAS, uncertainty about the outcome of surgery, loss of control, and exposure to strange instruments(robots). The data analysis revealed five primary themes: robot-assisted procedures, robotic arms, smaller incisions and recovery time, idea of technology role, and cutting edge. This study provides practical and valuable information about the adoption of robot-assisted surgery in surgical encounters. This study deepens our understanding of the factors that contribute to fear and anxiety resulting from interactions with surgical robots, while also broadening the scope of research on surgical robots. The healthcare providers can perform preoperative psychological evaluations to identify patients with a heightened susceptibility to anxiety and fear. Moreover, providing psychological assistance or therapy, and instructing patients on relaxation techniques and mindfulness practices help them to effectively cope with anxiety prior to and following surgical procedures.

The Effect of Osteoporosis on Complications and Reoperation Rates After Surgical Management of Adult Thoracolumbar Spinal Deformity: A Systematic Review and Meta Analysis.

Systematic Review. While substantial research has explored the impact of osteoporosis on patients undergoing adult spinal deformity (ASD) correction, the literature remains inconclusive. As such, the purpose of this study is to synthesize and analyze existing studies pertaining to osteoporosis as a predictor of postoperative outcomes in ASD surgery. We performed a systematic review and meta-analysis to determine the effect that a diagnosis of osteoporosis, based on ICD-10 coding, dual-energy X-ray absorptiometry (DEXA) or computed tomography, has on the incidence of adverse outcomes following surgical correction of ASD. Statistical analysis was performed using Comprehensive Meta-Analysis (Version 2) using a random effects model to account for heterogeneity between studies. After application of inclusion and exclusion criteria, 36 and 28 articles were included in the systematic review and meta-analysis, respectively. The meta-analysis identified greater rates of screw loosening amongst osteoporotic patients (70.5% vs 31.9%, P = .009), and decreased bone mineral density in patients who developed proximal junctional kyphosis (PJK) (.69 vs .79g/cm2, P = .001). The systematic review demonstrated significantly increased risk of any complication, reoperation, and proximal junctional failure (PJF) associated with reduced bone density. No statistical difference was observed between groups regarding fusion rates, readmission rates, and patient-reported and/or functional outcome scores. This study demonstrates a higher incidence of screw loosening, PJK, and revision surgery amongst osteoporotic ASD patients. Future investigations should explore outcomes at various follow-up intervals in order to better characterize how risk changes with time and to tailor preoperative planning based on patient-specific characteristics.

Holmium laser enucleation for large prostate hyperplasia: assessment of functional outcomes and postoperative complications

Introduction. To date, there has been insufficient research into the prostate volume as a factor that may influence the effectiveness and safety of surgical treatments. With the advent of relatively new laser techniques, it is important to take a closer look at this parameter, especially considering the success of these techniques in the treatment of benign prostatic hyperplasia (BPH) of various volumes.Objective. To assess the functional outcomes and postoperative complications of holmium laser enucleation of the prostate (HoLEP) depending on its volume.Materials & Methods. We performed a prospective study of HoLEP on 252 patients. Patients were divided into two groups according to their prostate volume: Group I included 206 patients (81%) with a prostate volume of < 100 mL, and Group II included 46 patients (19%) with a prostate volume ≥ 100 mL.Results. The prostate volume was the most significant prognostic factor regarding duration of surgery. This indicator significantly differed between the two groups. Group I had an average surgery time of 67.1 ± 26.7 minutes, while Group II had a time of 98.1 ± 24.2 minutes (p < 0.05). There were no significant differences in the number of complications between the groups — 36 cases (17.5%) in Group I and 12 cases (26%) in Group II, as well as functional results of urination between the groups. In the early postoperative period, the Q max in Group I was 17.4 ± 9.1 ml/s, in Group II — 18.2 ± 10.9 ml/s (p > 0.05), PVR — 52 ± 39.4 and 56 ± 31.8 ml (p > 0.05), respectively. After 3 months of observation, there were also no differences in the studied parameters: IPSS — 5.7 ± 4.1 vs 6.2 ± 4.9 points; QoL — 1.0 ± 0.9 vs 1.1 ± 0.9 points; Q max — 18.9 ± 6.7 vs 20.3 ± 11.5 ml/s; PVR — 53.5 ± 33.1 vs 54.9 ± 30.6 ml (p > 0.05).Conclusion. HoLEP is an effective and safe method of treating patients with different volumes of BPH. However, the duration of the procedure is an important factor that influences the surgery outcome, as it correlates with the prostate volume.

Quality of Life Outcomes After Pediatric Otitis Media Surgery: A Systematic Review and Meta-Analysis.

Systematically review of literature characterizing health-related quality of life (HRQoL) impact of surgery in pediatric otitis media (OM) patients, and meta-analysis of studies using the OM-6 questionnaire. Pubmed, EMBASE, Cochrane Library, Scopus. A systematic review of literature of studies evaluating HRQoL outcomes for OM patients managed by surgery. Two investigators independently reviewed abstracts and full-length articles. Risk of bias was assessed using the MINORS criteria and Cochrane Risk of Bias 2 tool. The search yielded 1272 studies, 50 underwent full-text review and 23 met inclusion criteria. Non-randomized studies were of moderate to good quality, while randomized trials had a high risk of bias. Age ranged from 6 months to 15 years. Race and socioeconomic factors were inconsistently reported. There were 11 HRQoL outcome measure instruments of which four were disease-specific. Eleven studies used OM-6 and nine were included in the meta-analysis. Pooled analysis of five studies showed a mean OM-6 change of 1.79 (95% CI: 1.53-2.06; 95% PI: 0.92-2.67; I2 = 68%) 4-6 weeks after surgery; a mean change of 1.87 (95% CI: 1.15-2.58; 98%) after 6 months across two studies; and a mean change of 1.64 (1.02 to 2.27; -6.35 to 9.64; 98%) after 9-13 months across three studies. There is no consistency in HRQoL instruments used to evaluate pediatric OM surgery outcomes in current literature with few RCTs. Meta-analysis showed a clinically significant large improvement in HRQoL 4-6 weeks after tympanostomy tube placement. N/A Laryngoscope, 2024.

Procedure Risk vs Frailty in Outcomes for Elderly Emergency General Surgery Patients: Results of a National Analysis.

The direct association between procedure risk and outcomes in elderly emergency general surgery (EGS) patients has not been analyzed. Studies only highlight the importance of frailty. A comprehensive analysis of relevant risk factors and their association with outcomes in elderly EGS patients is lacking. We hypothesized that procedure risk has a stronger association with relevant outcomes in elderly EGS patients compared to frailty. Elderly patients (age > 65) undergoing emergency general surgery operative procedures were identified in the NSQIP) database (2018 to 2020) and stratified based on the presence of frailty calculated by the Modified 5 Item Frailty Index (mFI-5; mFI 0 Non-Frail, mFI 1-2 Frail, and mFI ≥3 Severely Frail) and based on procedure risk. Multivariable regression models and Receiving Operative Curve (ROC) analysis were used to determine risk factors associated with outcomes. A total of 59,633 elderly EGS patients were classified into non-frail (17,496; 29.3%), frail (39,588; 66.4%), and severely frail (2,549; 4.3%). There were 25,157 patients in the low-risk procedure group and 34,476 in the high-risk group.Frailty and procedure risk were associated with increased mortality, complications, failure to rescue, and readmissions. Differences in outcomes were greater when patients were stratified according to procedure risk compared to frailty stratification alone. Procedure risk had a stronger association with relevant outcomes in elderly EGS patients compared to frailty. Assessing frailty in the elderly EGS patient population without adjusting for the type of procedure or procedure risk ultimately presents an incomplete representation of how frailty impacts patient-related outcomes.

Outcomes of Immediate Total Thyroidectomy in First-Side Loss of Neuromonitoring Signal

Use of intraoperative neuromonitoring (IONM) during thyroidectomy can nearly eliminate the risk of postoperative bilateral vocal cord palsy (VCP) by indicating staged surgery in cases of loss of signal (LOS) on the first side of planned total thyroidectomy. However, aborting planned total thyroidectomy may lead to persistence of symptoms, delay in adjuvant treatment, and patient inconvenience and distress. There are few data to guide a selective approach to total thyroidectomy in patients with first-side LOS. To investigate outcomes of immediate bilateral surgery in patients undergoing total thyroidectomy with first-side LOS. This cohort study was a retrospective review of outcomes for patients undergoing thyroidectomy between January 2016 and July 2023 at an academic tertiary referral center for thyroid surgery. Consecutive patients scheduled for total thyroidectomy using IONM were included. Exclusion criteria were preoperative VCP, deliberate sacrifice of recurrent laryngeal nerve (RLN), inadvertent RLN resection, and surgery performed without IONM. Total thyroidectomy performed using IONM. Vocal mobility on first postoperative day as assessed by flexible laryngoscopy; secondary outcome measures included subjective voice assessment, other postoperative complications, and long-term vocal mobility. Among 400 patients undergoing planned total thyroidectomy (mean age, 50.5 years [range, 4-88 years]; 318 female [79.5%]), 51 (12.8%) had first-side LOS, of whom 37 (9.3%) had persistent LOS. Twenty-nine patients (56% of procedures with first-side LOS, including 18 with persistent LOS) proceeded to immediate total thyroidectomy. Postoperatively, 16 patients (55% of patients undergoing total thyroidectomy following first-side LOS, including 14 of 18 with persistent LOS) had impaired vocal mobility. One patient had bilateral VCP that did not require tracheostomy, and 2 had postoperative hypoparathyroidism. Of those whose surgery was aborted after first-side LOS, 8 of 22 (36%) underwent completion thyroidectomy at a later stage. In those undergoing completion thyroidectomy, 2 of 8 (25%) had temporary VCP after the second surgery, 2 (25%) had permanent hypoparathyroidism, and 1 (12.5%) developed inoperable cancer. Postoperative VCP was fully reversible in all but 1 patient. Among patients planned for total thyroidectomy who develop first-side LOS, immediate total thyroidectomy may be considered among those who have pressing reasons for same, and where surgical difficulties might be anticipated in a secondary surgery.

Native lung surgery after single lung transplantation: clinical characteristics and outcomes.

Single lung transplantation (SLT) is a viable option for patients with end-stage pulmonary parenchymal and vascular diseases. However, various diseases can occur in native lungs after SLT. Between January 2000 and December 2021, 35 patients underwent cadaveric SLT and survived for more than 30days in our hospital. Among these 35 patients, 10 required surgery for diseases that developed in their native lungs. The clinical characteristics of these 10 patients and the outcomes of native lung surgery (NLS) were investigated. Among these ten patients, the indications for lung transplantation were chronic obstructive pulmonary disease and idiopathic interstitial pneumonia in three patients each, and lymphangioleiomyomatosis and collagen vascular disease-related interstitial pneumoniain two patients each. The causes of NLS included pneumothorax (n = 4), primary lung cancer (n = 2), native lung hyperinflation (n = 2), and pulmonary aspergilloma (n = 2). The surgical procedures were pneumonectomy (n = 7), lobectomy (n = 2), and alveolar-pleural fistula repair (n = 1). Only one postoperative complication, empyema, was treated with antibiotics. The 5-year overall survival rates after transplantation with and without NLS were 70.0% and 80.0%, respectively, and did not differ to a statistically extent (p = 0.56). NLS is an effective treatment option for diseases that develop in the native lungs after SLT.

Provider's exposure to diversity contributes to socioeconomic disparities in lumbar and cervical fusion outcomes

BackgroundStudies report patient race, income, and education influence spinal fusion outcomes; fewer studies, however, examine the influence of provider factors such as exposure to diversity or cultural sensitivity. ObjectiveTo examine how providers’ experience with diverse patient populations affects spinal fusion outcomes. MethodsRetrospective review of 39,680 patients undergoing lumbar and cervical fusions, 2003–2021, in Clinformatics® Data Mart national database. We used the provider patient racial diversity index (pRDI)—a published metric of physician exposure to diverse patients—to divide patients into groups based their provider's category (I, II, III) where patients treated by category III providers had surgeons with the most diverse patient populations. Multivariate regression models on propensity score-matched cohorts examined the association between patient SES and provider category on post-operative outcomes. ResultsBlack patients had decreased discharge home (OR 0.67; 95% CI 0.54–0.83) compared to white patients. Patients treated by category III providers had increased length of stay (Coeff. 0.62; 95% CI 0.43–0.81), charge (Coeff. 36800; 95% CI 29,200–44,400), and decreased discharge home (OR 0.90; 95% CI 0.83–0.97) compared to patients treated by category I providers. Asian patients treated by category II providers had decreased readmission (OR 0.38; 95% CI 0.14–0.96), and Black patients treated by category III providers had increased discharge home (OR 1.41; 95% CI 1.1–1.9) compared to those treated by category I providers. ConclusionWhile our study found two specific instances of improved spine surgery outcomes for minority patients treated by providers serving diverse patient populations, we present mixed findings overall. This study serves as the foundation for future research to better understand how provider pRDI affects outcomes in patients undergoing lumbar and cervical spine surgery.

Analysis of the Prognostic Factors That Influence the Outcome of Periapical Surgery, including Biomimetic Membranes for Tissue Regeneration: A Review.

The objective of this study was to analyze the prognostic factors that influence the outcome of periapical surgery. A systematic search of the literature was carried out using PubMed and Scopus databases between January 2000 and December 2023 with no language limitations. The PICO question of the present systematic review was: What prognostic factors may influence the outcome of periapical surgery? The most relevant randomized controlled clinical trials (RCTs), prospective clinical trials, retrospective studies, and meta-analyses (n = 44) were selected from 134 articles. The reviewed literature evidenced that bone-lesion healing could significantly be improved by the absence of deep periodontal pockets (>4 mm), localization in anterior teeth, the absence of pain and/or preoperative symptoms, a size of bone lesion < 5 mm, the use of ultrasound, the correct placement of retrograde filling material, and the use of different biomimetic membranes for guided tissue regeneration (GTR). Some preoperative and intraoperative factors could significantly improve the prognosis of periapical surgery. However, these results were not conclusive, and further high-quality research is required.

Surgery Advances in Gynecologic Tumors: The Evolution and Outcomes of Robotic Surgery for Gynecologic Cancers in a Tertiary Center.

The integration of innovation into routine clinical practice is faced with many challenges. In 2007, we received the mandate to evaluate how the introduction of a robotic program in gynecologic oncology affected patient-centered care by studying its impact on clinical outcomes and hospital resource utilization. Here we summarize the history and experience of developing a robotic surgery program for gynecologic cancers over 16 years. Analysis of the data indicates that robotic surgery improved perioperative patient clinical parameters, decreased blood loss, complications, and hospital stay, maintained the oncologic outcome, and is cost-effective, resulting in it becoming the dominant surgical approach in gynecologic oncology in a tertiary cancer care institution.

The Impact of Postoperative COVID-19 Infection on 30-day Outcomes of Laparoscopic Cholecystectomy.

Introduction: Preoperative Coronavirus Disease 2019 (COVID-19) infections are associated with postoperative adverse outcomes. However, there is limited data on the impact of postoperative COVID-19 infection on postoperative outcomes of common general surgery procedures.Objective: To evaluate the impact of postoperative COVID-19 diagnosis on laparoscopic cholecystectomy outcomes.Methods: Patients with symptomatic cholelithiasis, acute cholecystitis, or gallstone pancreatitis who underwent laparoscopic cholecystectomy with or without intraoperative cholangiogram were identified using the 2021 National Surgical Quality Improvement Program (NSQIP) database. Patients were categorized into two groups: patients with and without a postoperative COVID-19 diagnosis. Coarsened Exact Matching was used to match the groups based on preoperative risk factors, and outcomes were compared.Results: A total of 47,948 patients were included. In the aggregate cohort, 31% were male, and mean age was 50years. Age, BMI, smoking, COPD, CHF, preoperative sepsis, and ASA class were significantly different between the two groups. After matching, there were no differences in characteristics. 30-day morbidity (OR = 2.7, 95% CI 1.4-5.1), pneumonia (OR = 5.0, 95% CI 1.7-15.0), DVT (OR = 8.22, 95% CI 1.0-66), reoperation (OR = 9.3, 95% CI 1.2-73.8), and readmission (OR = 4.8, 95% CI 2.3-10.1) continued to be significantly worse in the matched cohort.Conclusion: Postoperative COVID-19 infection was associated with worse outcomes after laparoscopic cholecystectomy. These findings suggest that even postoperative COVID-19 diagnosis increases the risk for adverse outcomes in patients recovering from laparoscopic cholecystectomy and may indicate that precautions should be taken and new COVID-19 infections even after surgery should be closely monitored.

Long Term Surgical and Radiological Outcome of Discoid Lateral Meniscus: An Updated Systematic Review.

This study aimed to reach a consensus for ideal surgical treatment of discoid lateral meniscus (DLM) and to evaluate its long term surgical and radiological outcome. All authors independently searched for peer reviewed publications with keywords like discoid lateral meniscus, tibial menisci abnormalities, tibial menisci surgery and clinical outcome and their representative Medical Subjects Headings (MeSH) in databases of PubMed, EBSCO, Cochrane Central Register of Controlled Trials, from inception to December 2022. Original articles in English language on discoid lateral meniscus reporting clinical, surgical, or radiological outcomes with five or more years of follow-up were included in this systematic review. Study details and outcome data were analysed according to the age, follow-up period, kind of surgery, DLM type, and alignment. Our search strategy yielded 654 articles in PubMed, 222 articles in EBSCO and 5 articles in CENTRAL i.e. a total of 881 articles. After detailed assessment and screening, 12 articles were included in the final analysis, which included 444 DLM cases. The mean patient age at surgery ranged from 9.9 to 35.9years, and the mean follow-up period ranged from 5.2 to 16years. Partial meniscectomy and meniscoplasty are the recommended treatment because of the concerns of degenerative arthritis development after the total and subtotal meniscectomies. Two studies have documented better results with meniscal allograft transplantation. Satisfactory clinico-radiological outcome can be obtained after surgical treatment of discoid lateral meniscus with meniscus reshaping and repair of peripheral unstable part. Meniscal allograft transplantation (MAT) is gaining popularity in patients with total meniscectomy with satisfactory long term functional outcome.

Influence of Changes in Patella Indices on Total Knee Replacement Surgery Outcomes.

Total knee replacement is increasingly widely prescribed, not only for degenerative joint disease but also for other problems such as articular cartilage disease, misalignment due to causes other than degeneration, bone and joint cancer, and diseases that cause joint destruction. However, changes in knee joint biomechanics as well as complications of the patellofemoral joint after surgery lead to instability, joint pain, patellar rupture, and patellar tendon rupture. These are issues that challenge surgeons as well as make patients hesitant when considering knee replacement surgery. Understanding the changes in patella index that can occur after total knee replacement surgery will help surgeons carefully evaluate patients before surgery and calculate intraoperative techniques to minimize complications. Fifty-eight patients with 62 knees were diagnosed with osteoarthritis and underwent total knee replacement surgery. All patients had clinical and radiographic evaluation of the knee joint before and after surgery. Patellar indexes did not change significantly after surgery compared to before surgery. Before surgery, 2 patients (3.23%) had true patella baja. After surgery, 7 patients (11.29%) had true patella baja and 3 patients (4.84%) had pseudo-patella baja. The average knee flexion amplitude after surgery was 103.11±15.440, with only 2 patients losing extension >50º. The average KS score after surgery was 83.69±9.98, significantly improved compared to before surgery 33.44±11.38. Similarly, KFS score after surgery was 81.01±8.84 compared to before surgery 37.05±8.08. Changes in index of the patella before and after surgery affect the surgical results, the normal patella group has better results than the group with patella baja.

Value of Spinal Infection Treatment Evaluation Score, Pola Classification, and Brighton Spondylodiscitis Score from Decision to Surgery in Patients with Spondylodiscitis: A Receiver-Operating Characteristic Curve Analysis.

This was a retrospective study. This study aimed to assess the value of the Spinal Infection Treatment Evaluation (SITE) score, Brighton Spondylodiscitis Score (BSDS), and Pola classification to predict the need for surgical intervention in patients with spondylodiscitis. Spondylodiscitis is a rare disease, and the prediction of its outcome is crucial in the decision-making process. All case records were assessed to extract information on the American Spinal Injury Association (ASIA), Visual Analog Scale (VAS), and Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores before and after surgery. The SITE score, Pola classification, and BSDS were recorded. The receiver-operating characteristic (ROC) curve analysis and the area under the curve (AUC) were applied to estimate the predictive ability of the scoring systems. Patients' satisfaction with surgery outcomes was evaluated using the VAS, ASIA, JOABPEQ, and Likert scale for quality-of-life evaluation. In all 148 patients, case records were reviewed. The mean±standard deviation age of the patients was 54.6±14.7 years. Of these, 112 patients underwent surgery. The AUC scores were 0.86, 0.81, and 0.73 for the SITE score, BSDS, and Pola classification, respectively. In the comparison of the AUC of ROC curves, SITE score vs. BSDS showed a significantly greater AUC, 0.13 (Z =2.1, p =0.037); SITE score vs. Pola classification, 0.05 (Z =0.82, p =0.412); and Pola classification vs. BSDS, 0.08 (Z =1.22, p =0.219). The optimal cutoff score was 8.5 (sensitivity, 80.6%; specificity, 81.2%) for the SITE score and 9.5 (sensitivity, 52.8%; specificity, 83.0%) for the BSDS in the decision to surgery. VAS back pain and JOABPEQ subscales showed a significant difference when compared with preoperative scores. According to ASIA grading, none of the patients experienced neurological deterioration. Overall, patients' satisfaction was observed. The findings suggest that the SITE score is a useful measure and helps clinicians make clinically sound decisions in patients with spondylodiscitis.

Repeat Surgery after Percutaneous Endoscopic Lumbar Discectomy for Adolescent Lumbar Disc Herniation: A Multicenter Observational Study.

The reported date in the repeat surgical intervention for adolescent lumbar disc herniation (ALDH) after percutaneous endoscopic lumbar discectomy (PELD) was quite scarce. This study aims to introduce cases of repeat surgeries after PELD for ALDH and assess the incidence, chief causes, repeat surgery methods, and surgical outcomes of repeat surgeries after PELD for ALDH. A retrospective multicenter observational study was conducted on patients undergoing repeat surgeries after PELD for ALDH at four tertiary referral hospitals from January 2014 through August 2022. The incidence of repeat surgeries, chief causes, strategies for repeat surgeries, and timing of repeat surgeries were recorded and analyzed. The clinical outcomes were evaluated by the Numeric Rating Scales (NRS) scores and the modified MacNab criteria. Statistical analyses were performed with the Wilcoxon signed-rank test. A total of 23 patients who underwent repeat surgeries after PELD for ALDH were included. The chief causes were re-herniation (homo-lateral re-herniation at the same level, new disc herniation of adjacent level). The repeat surgery methods were revision PELD, micro-endoscopic discectomy (MED), open discectomy and instrumented lumbar inter-body fusion. The NRS scores decreased significantly in follow-up evaluations and these scores demonstrated significant improvement at the last follow-up (p < 0.002). For the modified MacNab criteria, at the last follow-up, 18 patients (78.26%) had an excellent outcome, and the overall success rate was 86.95%. This study's data suggest that young patients who underwent repeat surgery improved significantly compared to baseline. The chief cause was re-herniation. Revision PELD was the main surgical procedure, which provides satisfactory clinical results in young patients who underwent repeat surgeries.

Outcome of Epilepsy Surgery for Extratemporal Focal Cortical Dysplasia

Outcome of Epilepsy Surgery for Extratemporal Focal Cortical Dysplasia

Impact of enhanced recovery program implementation on postoperative outcomes after liver surgery: a monocentric retrospective study.

It is still unclear whether enhanced recovery programs (ERPs) reduce postoperative morbidity after liver surgery. This study investigated the effect on liver surgery outcomes of labeling as a reference center for ERP. Perioperative data from 75 consecutive patients who underwent hepatectomy in our institution after implementation and labeling of our ERP were retrospectively compared to 75 patients managed before ERP. Length of hospital stay, postoperative complications, and adherence to protocol were examined. Patient demographics, comorbidities, and intraoperative data were similar in the two groups. Our ERP resulted in shorter length of stay (3 days [1-6] vs. 4 days [2-7.5], p = 0.03) and fewer postoperative complications (24% vs. 45.3%, p = 0.0067). This reduction in postoperative morbidity can be attributed exclusively to a lower rate of minor complications (Clavien-dindo grade < IIIa), and in particular to a lower rate of postoperative ileus, after labeling. (5.3% vs. 25.3%, p = 0.0019). Other medical and surgical complications were not significantly reduced. Adherence to protocol improved after labeling (17 [16-18] vs. 14 [13-16] items, p < 0.001). The application of a labeled enhanced recovery program for liver surgery was associated with a significant shortening of hospital stay and a halving of postoperative morbidity, mainly ileus.
