Clinical Implementation of Tissue-Sparing Posterior Cervical Fusion: Addressing Market Access Challenges.

Background: The traditional open midline posterior cervical spine fusion procedure has several shortcomings. It can cause soft tissue damage, muscle atrophy, compromise of the lateral masses and painful prominent posterior cervical instrumentation or spinous process if there is dehiscence of the fascia. Additionally, patients frequently experience the rapid development of adjacent segment disease, which can result in the reemergence of debilitating pain and functional impairment. Clinical relevance: Tissue-sparing posterior cervical fusion is an alternative method for treating patients with symptomatic cervical degenerative disc disease. However, widespread clinical adoption has been challenged by ambiguity, misunderstandings and misinterpretations regarding appropriate procedural reimbursement coding. Technological advancement: The tissue-sparing posterior cervical fusion procedure was approved by the US Food and Drug Administration (FDA) in 2018 (CORUS™ Spinal System and CAVUX® Facet Fixation System (CORUS/CAVUX); Providence™ Medical Technology). This technique addresses the concerns with traditional spine fusion methods by achieving the stability and outcomes of posterior cervical fusion without the morbidity associated with significant muscle stripping in the traditional approach. This technology uses specialized implants and instrumentation to perform all of the steps required to facilitate bone fusion and provide stability while minimizing tissue disruption. The technique involves extensive bone preparation for fusion and placement of specialized stabilization implants that span the facet joint, promoting natural bone growth and fusion while reducing the need for extensive exposure. This procedure provides an effective, less invasive solution for patients with cervical degenerative disc disease. Reimbursement and coding clarity: The article provides a comprehensive rationale for appropriate reimbursement coding for tissue-sparing posterior cervical fusion. This is a critical aspect for the adoption and accessibility of medical technologies. This information is crucial for practitioners and healthcare administrators, ensuring that innovative procedures are accurately coded and reimbursed. Procedural details and clinical evidence: By detailing the procedural steps, instruments used and the physiological basis for the procedure, this article serves as a valuable educational resource for spine surgeons and payers to appropriately code for this procedure. Conclusions: The description of work for CORUS/CAVUX is equivalent to the current surgical standard of lateral mass screw fixation with decortication and onlay posterior grafting to facilitate posterior fusion. Thus, it is recommended that CPT codes 22600/22840 be used, as they best reflect the surgical approach, instrumentation, decortication, posterior cervical fusion and bone grafting procedures.

Predicting Risk of Post-Operative Morbidity and Mortality following Gynaecological Oncology Surgery (PROMEGO): A Global Gynaecological Oncology Surgical Outcomes Collaborative Led Study.

The medical complexity of surgical patients is increasing, and surgical risk calculators are crucial in providing high-value, patient-centered surgical care. However, pre-existing models are not validated to accurately predict risk for major gynecological oncology surgeries, and many are not generalizable to low- and middle-income country settings (LMICs). The international GO SOAR database dataset was used to develop a novel predictive surgical risk calculator for post-operative morbidity and mortality following gynecological surgery. Fifteen candidate features readily available pre-operatively across both high-income countries (HICs) and LMICs were selected. Predictive modeling analyses using machine learning methods and linear regression were performed. The area-under-the-receiver-operating characteristic curve (AUROC) was calculated to assess overall discriminatory performance. Neural networks (AUROC 0.94) significantly outperformed other models (p < 0.001) for evaluating the accuracy of prediction across three groups, i.e., minor morbidity (Clavien-Dindo I-II), major morbidity (Clavien-Dindo III-V), and no morbidity. Logistic-regression modeling outperformed the clinically established SORT model in predicting mortality (AUROC 0.66 versus 0.61, p < 0.001). The GO SOAR surgical risk prediction model is the first that is validated for use in patients undergoing gynecological surgery. Accurate surgical risk predictions are vital within the context of major cytoreduction surgery, where surgery and its associated complications can diminish quality-of-life and affect long-term cancer survival. A model that requires readily available pre-operative data, irrespective of resource setting, is crucial to reducing global surgical disparities.

Latest Progress in Risk-Adapted Surgery for Medullary Thyroid Cancer.

(1) Background: The wider adoption of a preoperative ultrasound and calcitonin screening complemented by an intraoperative frozen section has increased the number of patients with occult sporadic medullary thyroid cancer (MTC). These advances offer new opportunities to reduce the extent of the initial operations, minimizing operative morbidity and the risk of postoperative thyroxin supplementation without compromising the cure. (2) Methods: This systematic review of the international literature published in the English language provides a comprehensive update on the latest progress made in the risk-adapted surgery for sporadic and hereditary MTC guided by an intraoperative frozen section. (3) Results: The current evidence confirms the viability of a hemithyroidectomy for desmoplasia-negative sporadic MTC. To add an extra safety margin, the hemithyroidectomy may be complemented by a diagnostic ipsilateral central node dissection. Despite the limited extent of the surgery, all the patients with desmoplasia-negative sporadic tumors achieved a biochemical cure with excellent clinical outcomes. A hemithyroidectomy decreases the need for postoperative thyroxine substitution, but a total thyroidectomy may be required for bilateral nodular thyroid disease. Hereditary MTC is a different issue. Because each residual thyroid C cell carries its own risk of malignant progression, a total thyroidectomy remains mandatory for hereditary MTC. (4) Conclusion: In experienced hands, a hemithyroidectomy, which minimizes morbidity without compromising the cure, is an adequate therapy for desmoplasia-negative sporadic MTC.

Impact of fine-needle aspiration cytology in thyroidectomy extent and associated surgical morbidity in thyroid cancer.

PURPOSE: To assess the impact of fine-needle aspiration cytology (FNAC) in the extent of surgery in patients with thyroid cancer (TC) and the associated surgical morbidity in primary and completion setting. METHODS: A Swedish nationwide cohort of patients having surgery for TC (n = 2519) from the Scandinavian Quality Register for Thyroid, Parathyroid and Adrenal surgery between 2004 and 2013 was obtained. Data was validated through scrutinizing FNAC and histology reports. RESULTS: Among the 2519 cases operated for TC, the diagnosis was substantiated and validated through the histology report in 2332 cases (92.6%). Among these, 1679 patients (72%) were female, and the median age at TC diagnosis was 52.3 years (range 18-94.6). Less than total thyroidectomy (LTT) was undertaken in 944 whereas total thyroidectomy (TT) in 1388 cases. The intermediate FNAC categories of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/ FLUS), as well as suspicion for follicular neoplasm (SFN) lesions were more often encountered in LTT (n = 314, 33.3%) than TT (n = 63, 4.6%), whereas FNACs suspicion for malignancy and/or malignancy were overrepresented in TT (n = 963, 69.4%). Completion thyroidectomies were undertaken in 553 patients out of 944 that initially had LTT. In 201 cases with cancer lesions > 1 cm, other than FTC (Follicular TC)/ HTC (Hürthle cell TC) subjected to primary LTT, inadequate procedures were undertaken in 81 due to absent, Bethesda I or II FNAC categories, preoperatively. Complications at completion of surgery in this particular setting were 0.5% for RLN palsy (n = 1) and 1% (n = 2) for hypoparathyroidism 6 months postoperatively. The overall postoperative complication rate was higher in primary TT vs. LTT for RLN palsy (4.8% [n = 67] vs. 2.4% [n = 23]; p = 0.003) and permanent hypoparathyroidism (6.8% [n = 95] vs. 0.8% [n = 8]; p < 0.0001). CONCLUSIONS: FNAC results appear to affect surgical planning in TC as intermediate FNAC categories lead more often to LTT. Overall, inadequate procedures necessitating completion surgery are encountered in up to 15% of TC patients subjected to LTT due to absent, inconclusive, or misleading FNAC, preoperatively. However, completion of thyroidectomy in this setting did not yield significant surgical morbidity. Primary LTT is a safer primary approach compared to TT in respect of RLN palsy and permanent hypoparathyroidism complication rates; therefore, primary TT should probably be reserved for lesions > 1 cm or even larger with suspicion for malignancy or malignant FNAC.

Maternal and neonatal outcomes associated with multiple repeat cesarean deliveries: A registry-based study from Qatar.

BACKGROUND: Cesarean delivery (CD) is associated with increased maternal and neonatal morbidity compared to vaginal delivery, particularly in cases classified as emergency procedures or when there are multiple CDs. This retrospective cohort study aims to examine the incidence of maternal and neonatal complications in women with multiple CDs. METHODS: This study used data from a national perinatal database obtained from a single tertiary maternity care hospital. Women who delivered a singleton live birth after 24 weeks of gestation by CD were stratified into five groups based on the number of CDs, with the last group having five or more CDs. The women were divided into those with five or more CDs (Group 5) versus those with fewer than five (Groups 1 to 4). The maternal outcomes included intra-operative surgical complications, blood loss, and intensive care unit (ICU) admission. The neonatal outcomes included preterm birth, neonatal ICU (NICU) admission, respiratory distress syndrome (RDS), and perinatal death. RESULTS: Of the 6,316 women in the study, 2,608 (41.3%) had a primary CD. 30.3%, 17.5%, and 7.3% of the cohort had their second, third, and fourth CDs, respectively. Women undergoing the 5th CD and above formed the remaining 3.5% (227). Women in Group 5 had the highest risk of suffering a surgical complication (3.1%, p = 0.015) and postpartum hemorrhage (7.5%, p = 0.010). 24% of babies in Group 5 were born preterm (p < 0.001). They also had a 3.5 times higher risk of having a surgical complication (RR = 3.5, 95% CI 1.6-7.6, p = 0.002), a 1.8 times higher risk of developing postpartum hemorrhage (RR = 1.8, 95% CI 1.1-2.9, p = 0.014), a 1.7 times higher risk of delivering between 32-37 weeks of gestation (RR = 1.7, 95% CI 1.3-2.2, p < 0.001), a higher risk of the baby getting admitted to NICU (RR = 1.3, 95% CI 1.0-1.6, p = 0.038), and developing RDS (RR = 1.5, 95% CI 1.2-2.0, p = 0.002) compared to Groups 1-4. The risks of neonatal outcomes such as NICU admission (RR 2.9, 95% CI 2.1-4.0) and RDS (RR 3.5, 95% CI 2.3-5.5) were much higher in elective CDs performed at term compared to preterm births (p < 0.001 for both). CONCLUSION: Maternal morbidity significantly increases with the increasing number of CD. The increased risk of RDS and NICU admissions in the neonate with multiple CDs reflects lower gestational age and birthweight in these groups-consideration of preoperative steroids for lung maturation in these women to reduce neonatal morbidity warrants further discussion.

Outcomes and Associated Extracardiac Malformations in Neonates from Colombia with Severe Congenital Heart Disease.

Congenital heart disease (CHD) is a common structural anomaly, affecting ~ 1% of live births worldwide. Advancements in medical and surgical management have significantly improved survival for children with CHD, however, extracardiac malformations (ECM) continue to be a significant cause of morbidity and mortality. Despite clinical significance, there is limited literature available on ECM in neonates with CHD, especially from Latin America. A cross-sectional study of neonates with severe CHD evaluated by the medical-surgical board team at Fundación Cardiovascular de Colombia from 2014 to 2019 was completed to characterize morbidity, mortality, surgical outcomes, and ECM. Demographics and surgical outcomes were compared between neonates with and without ECM. Medical record data were abstracted and descriptive statistical analysis was performed. Of 378 neonates with CHD, 262 had isolated CHD (69.3%) and 116 had ECM (30.7%). The most common ECM was gastrointestinal (n = 18, 15.5%) followed by central nervous system (n = 14, 12%). Most neonates required a biventricular surgical approach (n = 220, 58.2%). Genetic testing was performed more often for neonates with ECM (n = 65, 56%) than neonates with isolated CHD (n = 14, 5.3%). Neonates with ECM had lower birth weight, longer hospital stays, and higher postsurgical complications rates. There was no difference in survival between groups. Overall, Screening for ECM in neonates with CHD is important and identification of ECM can guide clinical decision-making. These findings have important implications for pediatric healthcare providers, especially in low- and middle-income countries, where the burden of CHD is high and resources for managing CHD and extracardiac malformations may be limited.

Thirty-day surgical morbidity and risk factors in pediatric brain tumor surgery: a 10-year nationwide retrospective study.

OBJECTIVE: Pediatric neuro-oncological surgery is often associated with significant risk; however, comprehensive data on surgical morbidity remain limited. The purpose of this study was therefore to provide national population-based data on both the incidence and characteristics of poor postoperative outcomes following pediatric intracranial neuro-oncological surgery. Additionally, the authors aimed to evaluate key risk factors for poor postoperative outcomes including overall morbidity, significant morbidity, and the most frequent types of morbidity. METHODS: The authors conducted a registry-based, nationwide, retrospective study including all children receiving surgical treatment for a CNS tumor over a 10-year period. Patients were identified using the Danish Childhood Cancer Registry, and 30-day morbidity was assessed through manual review of electronic health records. Significant morbidity was defined as complications in need of treatment under general anesthesia, ICU admission, or persistent neurological deficits at 30 days following surgery or death. Risk factors including sex, age, tumor location, tumor malignancy grade, and preoperative hydrocephalus were investigated using multivariate logistic regression analysis. RESULTS: A total of 349 children undergoing 473 tumor procedures were included, with an overall morbidity rate of 66.0% and a significant morbidity rate of 34.2%. The most frequent complications included neurological deficits (41.4%) and CSF-related morbidity consisting of CSF leaks, pseudomeningoceles, and postoperative hydrocephalus. Highly significant associations between infratentorial tumor location and both significant morbidity (OR 1.26, 95% CI 1.11-1.43; p < 0.001) and neurological deficits (OR 1.38, 95% CI 1.21-1.57; p < 0.001) were identified. In addition, younger age was revealed as a major risk factor of both postoperative CSF leakage and CSF-related morbidity in general. CONCLUSIONS: In this large, population-based cohort, the authors show that postoperative morbidity is frequent, occurring in about two-thirds of all patients, largely driven by neurological deficits and CSF-related complications. In addition, infratentorial tumor location and younger age emerged as key risk factors for poor postoperative outcomes.

The association of marital status with kidney cancer surgery morbidity - a retrospective cohort study.

Purpose: To better understand whether the marital status impacts 90-day postoperative outcomes following kidney cancer surgery. Methods: We performed a retrospective cohort study of adult patients undergoing elective partial or radical nephrectomy to manage kidney masses from 2003 to 2017 using the Premier Hospital Database, a national hospital discharge dataset. Multinomial logistic regression models controlling for a wide range of clinicodemographic, surgical, and hospital characteristics were used to assess an association between marital status and postoperative complications. The primary outcome was 90-day complications, including minor complications (Clavien grades 1-2), non-fatal major complications (Clavien grades 3-4), and mortality (Clavien grade 5). Secondary outcomes included patient disposition and readmission rates. Results: The study cohort comprised 106,752 patients, of which 61,188 (57.32%) were married. The overall incidence of minor complications, major complications, and death was 24.04%, 6.00%, and 0.71%, respectively. Marriage was associated with a significantly lower incidence of minor (RR 0.97; 95% CI: 0.94-0.99) complications following open or radical nephrectomy and major complications (RR 0.89; 95% CI: 0.84-0.95) for all surgical types and approaches. There was no association between marital status and mortality (RR 0.94; 95% CI: 0.81-1.10). Conclusion: Marriage is associated with a significant reduction in major complications following kidney cancer surgery, likely because it is associated with greater social support, which is beneficial in the postoperative phase of care. Marital status and social support may play a role in the preoperative decision-making process and counseling for patients considering kidney cancer surgery.

Enhance Safety in Aneurysm Surgery: Strategies for Prevention of Intraoperative Vascular Complications.

Complications during surgery for intracranial aneurysms can be devastating. Notorious pitfalls include premature rupture, parent vessel occlusion, local cerebral injury and brain contusion, and incomplete neck obliteration. These unfavorable intraoperative events can result in major neurological deficits with permanent morbidity and even mortality. Herein, the author highlights the relevant surgical strategies used in his daily practice of aneurysm surgery (e.g., aneurysm clipping with adenosine-induced temporary cardiac arrest), application of which may help prevent vascular complications and enhance surgical safety through reduction of the associated risks, thus allowing improvement of postoperative outcomes. Overall, all described methods and techniques should be considered as small pieces in the complex puzzle of prevention of vascular complications during aneurysm surgery.

Pectoralis Major in Salvage Total Laryngectomy after Irradiation: Morbidity, Mortality, Functional, and Oncological Results in a Referral Center in Egypt.

BACKGROUND: Nonsurgical organ preservation protocols have seen a large diffusion worldwide in the last decades. Their oncological and functional effectiveness in a real-world setting has been recently questioned because of the high morbidity of salvage procedures. The aim of this study is to review the outcomes of postirradiation salvage total laryngectomy (STL) and reconstruction with pectoralis major flap. METHODS: This retrospective observational study included 37 cases of STL in the period from January 2015 to December 2021. Data for each patient were extracted from the hospital information system and reviewed. RESULTS: The 3-year overall and disease-specific survival are, respectively, 28% and 51%. Only seven recurrences after salvage surgery were recorded and all of them died from the disease. The other 14 deaths derived from comorbidities, with diabetes being the most significant predictive parameter for overall survival. Also, lower postoperative albumin levels were associated with a higher risk of death. CONCLUSIONS: Overall survival after STL and reconstruction with PMMF is low but most deaths are due to comorbidities and not to cancer progression or recurrence.

Temporal trends of failure-to-rescue following perioperative complications in vulvar cancer surgery in the United States.

OBJECTIVE: Failure-to-rescue, defined as mortality following a perioperative complication, is a perioperative quality indicator studied in various surgeries, but not in vulvar cancer surgery. The objective of this study was to assess failure-to-rescue in patients undergoing surgical therapy for vulvar cancer. METHODS: This cross-section study queried the National Inpatient Sample. The study population was 31,077 patients who had surgical therapy for vulvar cancer from 1/2001-9/2015. The main outcomes were (i) perioperative morbidity (29 indicators) and (ii) mortality following a perioperative complication during the index admission for vulvar surgery (failure-to-rescue), assessed with a multivariable binary logistic regression model. RESULTS: The cohort-level median age was 69 years, and 14,337 (46.1%) had medical comorbidity. Perioperative complications were reported in 4736 (15.2%) patients during the hospital admission for vulvar surgery. In multivariable analysis, patient factors including older age, medical comorbidity, and morbid obesity, and treatment factors with prior radiotherapy and radical vulvectomy were associated with perioperative complications (P < 0.05). The number of patients with morbid obesity, higher comorbidity index, and prior radiotherapy increased over time (P-trends < 0.001). Among 4736 patients who developed perioperative complications, 55 patients died during the hospital admission for vulvar surgery (failure-to-rescue rate, 1.2%). In multivariable analysis, cardiac arrest (adjusted-odds ratio [aOR] 27.25), sepsis or systemic inflammatory response syndrome (aOR 11.54), pneumonia (aOR 6.03), shock (aOR 4.37), and respiratory failure (aOR 3.10) were associated with failure-to-rescue (high-risk morbidities). There was an increasing trend of high-risk morbidities from 2.0% to 3.7% over time, but the failure-to-rescue from high-risk morbidities decreased from 9.1% to 2.8% (P-trend < 0.05). CONCLUSION: Vulvar cancer patients undergoing surgical treatment had increased comorbidity over time with an increase in high-risk complications. However, failure-to-rescue rate has decreased significantly.

Postsurgical morbidity and mortality favorably informs deep brain stimulation for new indications including schizophrenia and schizoaffective disorder.

Background: Deep brain stimulation (DBS) shows promise for new indications like treatment-refractory schizophrenia in early clinical trials. In the first DBS clinical trial for treatment refractory schizophrenia, despite promising results in treating psychosis, one of the eight subjects experienced both a symptomatic hemorrhage and an infection requiring device removal. Now, ethical concerns about higher surgical risk in schizophrenia/schizoaffective disorder (SZ/SAD) are impacting clinical trial progress. However, insufficient cases preclude conclusions regarding DBS risk in SZ/SAD. Therefore, we directly compare adverse surgical outcomes for all surgical procedures between SZ/SAD and Parkinson's disease (PD) cases to infer relative surgical risk relevant to gauging DBS risks in subjects with SZ/SAD. Design: In the primary analysis, we used browser-based statistical analysis software, TriNetX Live (trinetx.com TriNetX LLC, Cambridge, MA), for Measures of Association using the Z-test. Postsurgical morbidity and mortality after matching for ethnicity, over 39 risk factors, and 19 CPT 1003143 coded surgical procedures from over 35,000 electronic medical records, over 19 years, from 48 United States health care organizations (HCOs) through the TriNetX Research Network™. TriNetXis a global, federated, web-based health research network providing access and statistical analysis of aggregate counts of deidentified EMR data. Diagnoses were based on ICD-10 codes. In the final analysis, logistic regression was used to determine relative frequencies of outcomes among 21 diagnostic groups/cohorts being treated with or considered for DBS and 3 control cohorts. Results: Postsurgical mortality was 1.01-4.11% lower in SZ/SAD compared to the matched PD cohort at 1 month and 1 year after any surgery, while morbidity was 1.91-2.73% higher and associated with postsurgical noncompliance with medical treatment. Hemorrhages and infections were not increased. Across the 21 cohorts compared, PD and SZ/SAD were among eight cohorts with fewer surgeries, nine cohorts with higher postsurgical morbidity, and fifteen cohorts within the control-group range for 1-month postsurgical mortality. Conclusions: Given that the subjects with SZ or SAD, along with most other diagnostic groups examined, had lower postsurgical mortality than PD subjects, it is reasonable to apply existing ethical and clinical guidelines to identify appropriate surgical candidates for inclusion of these patient populations in DBS clinical trials.

Using the Social Vulnerability Index to Examine Disparities in Surgical Pediatric Trauma Patients.

INTRODUCTION: The Social Vulnerability Index (SVI) is a composite measure geocoded at the census tract level that has the potential to identify target populations at risk for postoperative surgical morbidity. We applied the SVI to examine demographics and disparities in surgical outcomes in pediatric trauma patients. METHODS: Surgical pediatric trauma patients (≤18-year-old) at our institution from 2010 to 2020 were included. Patients were geocoded to identify their census tract of residence and estimated SVI and were stratified into high (≥70th percentile) and low (<70th percentile) SVI groups. Demographics, clinical data, and outcomes were compared using Kruskal-Wallis and Fisher's exact tests. RESULTS: Of 355 patients included, 21.4% had high SVI percentiles while 78.6% had low SVI percentiles. Patients with high SVI were more likely to have government insurance (73.7% versus 37.2%, P < 0.001), be of minority race (49.8% versus 19.1%, P < 0.001), present with penetrating injuries (32.9% versus 19.7%, P = 0.007), and develop surgical site infections (3.9% versus 0.4%, P = 0.03) compared to the low SVI group. CONCLUSIONS: The SVI has the potential to examine health care disparities in pediatric trauma patients and identify discrete at-risk target populations for preventative resources allocation and intervention. Future studies are necessary to determine the utility of this tool in additional pediatric cohorts.

Assessment of the Milan Complexity Scale for prediction of postoperative morbidity in pediatric neuro-oncological surgery.

PURPOSE: To assess the performance of the risk-predicting Milan Complexity Scale (MCS) on postoperative morbidity in pediatric neuro-oncological surgery. METHODS: A retrospective dual-center review of children undergoing primary brain tumor resection in Denmark over a 10-year period. MCS scoring was performed based on preoperative imaging, blinded to individual outcomes. Surgical morbidity was registered according to existing complication scales and dichotomized as significant or nonsignificant morbidity. The MCS was evaluated using logistic regression modeling. RESULTS: 208 children (50% female, mean age 7.9 y, and SD 5.2) were included. Of the original "Big Five" predictors included in the MCS, only posterior fossa (OR: 2.31, 95% CI: 1.25-4.34, p-value = 0.008) and eloquent area (OR: 3.32, 95% CI: 1.50-7.68, p-value = 0.004) locations were significantly associated with increased risk of significant morbidity in our pediatric cohort. The absolute MCS score correctly classified 63.0% of cases. Its accuracy increased to 69.2% when mutually adjusting for each of the "Big Five" predictors with corresponding positive and negative predictive values of 66.2% and 71.0%, using a predicted probability cutoff of 0.5. CONCLUSION: The MCS is predictive of postoperative morbidity also in pediatric neuro-oncological surgery, although only two of its original five variables were significantly associated with poor outcome in children. The clinical value of the MCS is likely limited for the experienced pediatric neurosurgeon. Future clinically impactful risk-prediction tools should include a larger number of relevant variables and be tailored to the pediatric population.

Prior vertical uterine incision: Effect on subsequent pregnancy characteristics and outcomes.

OBJECTIVE: To examine characteristics and outcomes of cesarean delivery (CD) in women with a history of vertical hysterotomy. METHOD: This is a comparative study that retrospectively queried the National Inpatient Sample from October 2016 to December 2018. Pregnancy characteristics and surgical outcomes of CD among 18 575 women with prior vertical uterine incision were compared to 1 072 949 women with prior low-transverse incision, assessed by multivariable generalized estimating equation model and propensity score weighting. RESULTS: In a multivariable analysis, women who had prior vertical uterine incision were more likely to have placenta percreta (odds ratio [OR] 3.41, 95% confidence interval [CI] 1.87-6.20), pre-labor uterine rupture (OR 2.70, 95% CI 1.52-4.80), in-labor uterine rupture (OR 2.33, 95% CI 1.55-3.51), and extreme preterm delivery <28 weeks (OR 17.8, 95% CI 15.2-20.7) in the current pregnancy, compared to those who had prior low-transverse uterine incision. In a weighted model, prior vertical hysterotomy was associated with increased surgical morbidity in current CD compared to prior low-transverse hysterotomy (10.6% vs. 4.8%, OR 2.02, 95% CI 1.81-2.26), including hemorrhage (OR 1.99, 95% CI 1.74-2.27) and hysterectomy (OR 3.67, 95% CI 2.97-4.53). CONCLUSION: Prior vertical uterine incision at CD was associated with increased risk of placenta percreta, uterine rupture, particularly before labor, and adverse outcomes in the subsequent pregnancy.

Utilizing preoperative arterial embolization to minimize blood loss at time of vulvar sarcoma resection: A case report.

Selective arterial embolization has long been utilized in the field of obstetrics and gynecology as both a prophylactic and therapeutic measure. We present a case of a highly vascularized, poorly differentiated, radiation-related vulvar sarcoma that was resected immediately following selective arterial embolization. Arterial embolization in patients with gynecologic malignancies has been shown to compromise blood supply to the tumor and decrease the risk of hemorrhage and related surgical complications. In this case, the use of embolization prior to surgery appeared to result in a less morbid procedure for the patient with decreased blood loss and improved quality of life thereafter. Based on the presented case, we believe that arterial embolization can be considered a safe preoperative intervention to decrease surgical risk, particularly hemorrhage, at time of resection of highly vascularized vulvar tumors.

PO2 21% oxygenated hypothermic machine perfusion in kidney transplantation: Any clinical benefit?

BACKGROUND: In deceased donor kidney transplantation (KT), the use of hypothermic machine perfusion (HMP) has been acquiring the status of best practice in the pre-transplant management of kidney grafts. Two types of HMP are currently available, oxygenated HMP and non-oxygenated HMP. However, data on the real clinical impact of oxygenation on KT outcome are still heterogeneous. METHODS: Retrospective study on a cohort of 103 patients transplanted with a single kidney graft that was managed either with end-ischemic oxygenated (O2 group, Waves Machine, n = 51, 49.5%) or non-oxygenated HMP (no-O2 group, Life Port Kidney Transporter Machine, n = 52, 50.5%), during the period January 2016-December 2020. Oxygenation was performed at pO2 21%. RESULTS: The median cold ischemia time was 29 h:40 min [IQR 26 h:55 min-31 h:10 min] and the prevalence of grafts from extended criteria donors (ECD) was 46.7%, with a median kidney donor profile index (KDPI) of 72 [41-94]. The study groups were homogeneous in terms of recipient characteristics, ischemia times and donor characteristics. O2 and no-O2 groups showed comparable outcomes in terms of delayed graft function (O2 vs no-O2, 21.5% vs 25%, p = 0.58), vascular (0.2% vs 0.2%, p > 0.99) and urologic (13.7% vs 11.5%, p = 0.77) complications, and episodes of graft rejection (11.7% vs 7.7%, p = 0.52). At 1 year follow up, even creatinine serum levels were comparable between the groups (1.27 mg/dL [1.09 and 1.67] vs 1.4 mg/dL [1.9-1.78], p = 0.319), with similar post-transplant trend (p = 0.870). No significant benefit was either observed in ECD or KDPI > 60 subgroups, respectively. CONCLUSIONS: Oxygenation at pO2 21% during HMP seems not to significantly enhance the KT outcomes in terms of postoperative complications or graft function.

Immediate postoperative complications after lateral ridge augmentation - a clinical comparison between bone shell technique and sticky bone.

Nowadays, implant dentistry is strongly interconnected to bone augmentation procedures. Lateral ridge augmentation is often an imperative treatment stage for successful, prosthetic-driven implant placement. This study aimed to comparatively analyze the immediate postoperative complications of two horizontal bone grafting procedures: sticky bone and bone shell technique. Records of patients with lateral ridge augmentation were analyzed to identify immediate postoperative complications. The study group included 80 patients divided into 40 control (bone-shell technique - BS) and 40 tests (sticky bone -SB). More patients reported moderate and severe pain in the BS - group (11 patients - 27.5%) than in the SB group (6 patients - 15%). In the BS group, the incidence of severe and moderate trismus, neurosensory disturbances, and important hematoma was higher. There was an increased inflammatory response following the bone shell technique, while the sticky bone technique proved reduced surgical morbidity. There was no difference between the two groups in the risk of dehiscence or infection.

The effect of major postoperative complications on recurrence and long-term survival after cytoreductive surgery for ovarian cancer.

OBJECTIVE: To assess the impact on survival of major postoperative complications and to identify the factors associated with these complications in patients with advanced ovarian cancer after cytoreductive surgery. METHODS: We designed a retrospective multicenter study collecting data from patients with IIIC-IV FIGO Stage ovarian cancer who had undergone either primary debulking surgery (PDS), early interval debulking surgery (IDS) after 3-4 cycles of neoadjuvant chemotherapy, or delayed debulking surgery (DDS) after 6 cycles, with minimal or no residual disease, from January 2008 to December 2015. Univariable and multivariable analyses were conducted to identify factors associated with major surgical complications (≥Grade 3). We assessed disease-free survival (DFS) and overall survival (OS) rates according to the occurrence of major postoperative complications. RESULTS: 549 women were included. The overall rate of major surgical complications was 22.4%. Patients who underwent PDS had a higher rate of major complications (28.6%) than patients who underwent either early IDS (23.2%) or DDS (14.0%). Multivariable analysis revealed that extensive peritonectomy and surgical timing were associated with the occurrence of major complications. Median DFS and OS were 16.9 months (95%CI = [13.7-18.4]) and 48.0 months (95%CI = [37.2-73.1]) for the group of patients with major complications, and 20.1 months (95%CI = [18.6-22.4]) and 56.7 months (95%CI = [51.2-70.4]) for the group without major complications. Multivariable analysis revealed that major surgical complications were significantly associated with DFS, but not with OS. CONCLUSIONS: Patients who experienced major surgical complications had reduced DFS, compared with patients without major morbidity. Extensive peritonectomy and surgical timing were predictive factors of postoperative morbidity.
