RATIONALE AND OBJECTIVES
The objective of this study was to measure the safety and efficacy of thermal ablation, including radiofrequency ablation (RFA) and microwave ablation (MWA), for patients with stage I non-small cell lung cancer (NSCLC).
MATERIALS AND METHODS
The databases PubMed was searched from inception to November 2023 to identify relevant studies. Statistical analyses were performed with R version 3. 6. 3.
RESULTS
Thirty-three studies involving 1400 patients were finally included. According to our study, the incidence of patients with stage I NSCLC who were older than 60 years old was 98 % (95 % CI [94-100 %]); the lesions were mostly located in RUL (Right Upper Lobe) and LUL (Left Upper Lobe), and the incidence of the two sites was 29 % (95 % CI [23-35 %]) and 27 % (95 % CI [21-33 %]), respectively; the types of lung cancers mainly included adenocarcinoma, squamous carcinoma, and large-cell lung cancer, of which adenocarcinoma accounted for the largest proportion of 63 % (95 % CI [56-70 %]); the causes of death were mainly categorized into cancer-related (57 %, 95 %CI[40-74 %]) and noncancer-related (40 %, 95 %CI [23-58 %]); the common complications in the postoperative period were pneumothorax and pain, with the incidence of 33 % (95 %CI[24-44 %]) and 33 % (95 %CI[19-50 %]), and the rate of the postoperative complications in MWA was slightly higher than those in RFA; the local recurrence rate was 23 % (95 %CI[17-29 %]) and the distant recurrence rate was 18 % (95 %CI[7-32 %]); the pooling result showed the rate of 1-, 2-, 3-, and 5-year survival rate were 96 %, 81 %, 68 %, and 42 %, the Cancer-specific survival (CSS) rates at 1, 2, 3, and 5 years were 98 %, 88 %, 75 %, and 58 %, Disease-free survival (DFS) rates at 1, 2, 3, and 5 years were 87 %, 63 %, 57 %, and 42 %, there were no significant differences existed between the RFA group and MWA group in survival rate, CSS and DFS.
CONCLUSION
Ablation therapy is safe and effective for stage I NSCLC patient. MWA and RFA have comparable efficacy, safety, and prognosis, which could be recommended for patients with stageⅠNSCLC, especially for patients who cannot tolerate open surgery.

BACKGROUND
The impact of sex on outcomes following surgical aortic valve replacement (SAVR) remains unclear. It has been proposed that females experience inferior outcomes, but this has yet to be conclusively established, particularly in the long term. The objective of this study is to identify discrepancies in postoperative outcomes between males and females following SAVR to better inform consideration for surgical intervention.
METHOD
We retrospectively reviewed the outcomes of 4,927 patients who underwent SAVR from 2004 to 2018 at our centre. In total, 531 propensity-matched males and females were included in the final analysis. The primary outcome was mortality at any point during the follow-up period. Secondary outcomes included various measures of postoperative morbidity. Follow-up duration was 15 years.
RESULTS
In SAVR all-comers, females experienced inferior short-term mortality, but equivalent mid-term and long-term mortality. Rates of mediastinal bleeding, sternal wound infections, sepsis, heart failure, and pacemaker insertion were all equivalent between the sexes; however, males experienced a higher rate of acute kidney injury and readmission for stroke at the longest follow-up while females experienced a longer intensive care unit and hospital length of stay. In a sub-analysis of isolated SAVR, males and females experienced equivalent early, mid, and late mortality. Of note, a trend towards increased aortic valve reoperation was noted in females at the longest follow-up.
CONCLUSIONS
Males and females experience equivalent long-term mortality following isolated SAVR. Sex is not an independent risk factor of poor outcomes post-SAVR; however, the increased preoperative risk profile of females requires diligent consideration.

INTRODUCTION
Late open conversion (LOC) following endovascular aneurysm repair (EVAR) is a rare complication with a high morbidity and mortality and is often proposed as the last line of treatment after failure of endovascular reintervention of any type. This study aimed to highlights the limitations of EVAR follow-up imaging in characterizing endoleaks, which may contribute to the failure of endovascular reinterventions and lead to LOC.
METHODS
This retrospective cohort study recruited all EVAR implanted in Amiens University Hospital (France) between January 2008 and December 2022. Elective LOC was defined as surgical conversion > 1 month after EVAR. The primary endpoint was the rate of wrong categorisation of endoleaks by follow-up exams before LOC. Secondary endpoints were the morbidity and the mortality associated with LOC.
RESULTS
Seven hundred and eight EVAR were performed in our institution, 30 required elective LOC. Twenty-five of them were treated for sac enlargement due to an endoleak (83,3%) (all types). Wrong categorisation of the endoleak was noted in 13 of the patients (52.2%). Twelve of these re-categorisations involved the preoperative diagnosis of a type II endoleaks (92.3%). The change in categorisation in 7 out of 12 cases (58%) was in favor of a type I endoleak, other re-categorisation included 1 Type III (8%), 4 Types IV (33%). One patient died during 30 days post-operative period and 7 patients (28%) presented a major complication, the median length of stay was 13 days (IQR 9-21).
CONCLUSION
Routine follow-up examinations such as angioscanner and contrast Doppler ultrasound appear to be limited in their ability to categorise the type of persistent endoleak, which may increase the number of patients requiring LOC. New precision diagnostic imaging techniques, such as dynamic examinations, need to be developed to limit the need for LOC.

OBJECTIVE
Assess subsequent cardiovascular events and all-cause mortality in patients with intact AAA treated by EVAR according to the existence of isolated EL at 1 year after EVAR implantation.
METHODS
This retrospective, single-centre study included patients treated with EVAR between 2010 and 2017 in the vascular surgery department of the University Hospital of Lyon with a infrarenal AAA > 50 mm. The baseline clinical characteristics collected just before EVAR were retrieved from electronic patient records of our institution. AAA characteristics, procedure and the one-year post-operative CTA were reported. Study endpoints, major adverse cardiovascular events (MACE), major adverse lower extremity events (MALE) and all-cause mortality, were recorded during follow-up. Patients were divided into 2 groups according to the presence of isolated EL (EL +) or absence (EL -) of any endoleak on CTA at 1 year. MACE, MALE and all-cause mortality were compared between both groups.
RESULTS
During the study period, 589 patients were treated by endovascular surgery and 207 were included. According to the CTA results at 1 year, 60 patients (29%) were included in the EL + group, and 147 patients (71%) in the EL - group. A total of 109 patients (53%) experienced a MACE or MALE; significantly fewer patients in the EL + than in the EL - group did so (p = .009). There were 47 patients (23%) who experienced at least one MALE, and the frequency was significantly lower in the EL + group (p = .017).
CONCLUSION
Patients with AAA treated by EVAR who did not develop EL at one year, were at higher risk of MALE during follow-up. This might be explained by more frequent symptomatic LEPAD at baseline in this group. These patients therefore require a closer follow-up and strict control of cardiovascular risk factors to prevent cardiovascular morbi-mortality.

Review
The complexity of cardiac electrophysiology procedures has increased significantly over the past three decades. Anesthesia requirements of these procedures can be different based on patient- and procedure-specific factors. This manuscript outlines various anesthesia strategies for cardiac implantable electronic devices and electrophysiology procedures including pre-procedural, procedural and post-procedural management. A team-based approach with collaboration between cardiac electrophysiologists and anesthesiologists is required with careful pre-procedural and intra-procedural planning. Given the recent advances in electrophysiology, there is a need for specialized cardiac electrophysiology anesthesia care to improve the efficacy and safety of the procedures.

Journal of Neurosurgery Jun 2024The objective of this study was to develop a nomogram to predict long-term facial nerve (FN) function after vestibular schwannoma (VS) resection.
OBJECTIVE
The objective of this study was to develop a nomogram to predict long-term facial nerve (FN) function after vestibular schwannoma (VS) resection.
METHODS
A retrospective cohort study of two tertiary academic skull base referral centers was performed. Consecutive adults > 18 years of age with sporadic unilateral VS who underwent resection between September 2016 and May 2021 were included. FN function in the immediate postoperative period and at the most recent evaluation was measured.
RESULTS
A total of 306 patients (mean age 49 years, 63% female) were included, with a mean follow-up of 18 months. The mean maximum tumor diameter was 19 mm (range 1-50 mm), and 80 (26.1%) tumors were > 25 mm. Overall, 85% of patients showed good immediate postoperative FN function (House-Brackmann [HB] grade I or II) and 89% maintained good FN function at > 12 months of follow-up. An intraoperative FN electromyographic (EMG) response ≥ 100 µV to 0.05 mA of stimulation (OR 18.6, p < 0.001) was the strongest predictor of good HB grade in the immediate postoperative period. EMG response ≥ 100 µV (OR 5.70, p < 0.001), tumor size ≤ 25 mm (OR 3.09, p < 0.05), and better immediate postoperative HB grade (OR 1.48, p = 0.005) predicted good long-term FN function on multivariable analysis. A point-of-care nomogram based on these data predicted long-term FN function with a sensitivity of 89% and specificity of 69%.
CONCLUSIONS
Better immediate postoperative HB grade, intraoperative FN EMG response ≥ 100 µV, and tumor size ≤ 25 mm strongly predicted good long-term FN function after VS resection. A point-of-care nomogram based on these variables could serve as a useful tool for postoperative counseling and prognosis of long-term FN recovery.

OBJECTIVE
Functional hemispherectomy is an effective surgical intervention for select patients with drug-resistant epilepsy. The last several decades have seen dramatic evolutions in preoperative evaluation, surgical techniques, and postoperative care. Here, the authors present a retrospective review of the medical records of 146 children who underwent hemispherectomy between 1987 and 2022 at The Hospital for Sick Children, providing a unique overview of the evolution of the procedure and patient outcomes over 35 years.
METHODS
The medical records of all children who underwent hemispherectomy at The Hospital for Sick Children between 1987 and 2022 were reviewed. Demographic information, preoperative clinical features, short-term and long-term seizure outcomes, and details regarding postoperative complications were recorded.
RESULTS
The seizure outcomes of 146 children were analyzed. There were 68 females and 78 males with a mean age of 5.08 years, 123 of whom demonstrated seizure freedom (Engel class IA) in the short-term postoperative follow-up period and 89 in the long term. The effectiveness of hemispherectomy in achieving long-term seizure control has improved over time (β = 0.06, p < 0.001). Factors associated with overall seizure freedom included younger age at the time of hemispherectomy and stroke as the etiology of seizures, as well as complete disconnection during the first surgery. Additionally, the etiologies of epilepsy for which hemispherectomy is performed have expanded over time, while complication rates have remained unchanged.
CONCLUSIONS
Hemispherectomy is an increasingly effective treatment for certain cases of drug-resistant epilepsy. The etiologies of epilepsy for which hemispherectomy is performed are broadening, with no change in its safety profile. Seizure outcomes are better when the etiology of epilepsy is an ischemic injury, and the most common complication after the procedure is hydrocephalus. These findings reinforce the ongoing use of hemispherectomy as a safe and effective treatment option for certain individuals with drug-resistant epilepsy, support its application to a broader range of etiologies, and highlight areas of future investigation.

Isolated popliteal artery occlusions are rare compared with femoropopliteal occlusive diseases. Although endovascular procedures have gained importance in treatment, conventional surgery remains the gold standard. In this study, we reviewed popliteal endarterectomy and patch plasty using a posterior approach. Fourteen patients who underwent surgery for isolated popliteal artery occlusions were retrospectively examined. Patients were assessed in terms of age, sex, and risk factors, such as accompanying diseases and smoking, surgical method and anesthesia, incision type, preoperative and postoperative pulse examination, ankle-brachial indices, patency, wound infection, postoperative complications, and the treatment applied. Twelve (85.7%) patients were male, and 2 (14.3%) were female. Limb ischemia was critical (ABI < 0.7) in 11 (78.5%) patients. The average duration of postoperative hospitalization was 8 ± 3.7 days on average, and the average length of follow-up was 17 ± 3.4 months. Thrombosis and complications requiring secondary intervention did not develop during the early postoperative period. While the patency rate in the first 6 months of follow-up was 100%, it was 92.8% in the 1st year and 85.7% in the 2nd year. Surgical treatment with the posterior approach in isolated popliteal artery lesions is preferred by vascular surgeons as a prioritized treatment method, with a sufficient recanalization rate and low perioperative morbidity and mortality rates. Furthermore, it is promising because it does not prevent below-knee femoropopliteal bypass, which is the subsequent stage of treatment. Moreover, the great saphenous vein was protected, and the acceptable early- and mid-term results were encouraging.

BACKGROUND
This study aimed to evaluate the clinical and radiological features of the patella fixation technique using Toggleloc suspension system in a single ellipsoidal blind patellar tunnel during medial patellofemoral ligament (MPFL) reconstruction.
METHODS
This study included 52 patients (25 men, 27 women) who underwent MPFL reconstruction using a semitendinosus tendon graft. The graft was fixed to the ellipsoidal single blind tunnel opened on the medial side of the patella with an endobutton and was fixed to the femoral tunnel by using bioabsorbable screw. Clinical scores (Kujala score, Lysholm score, Tegner activity score and the visual analog scale [VAS] score) were evaluated preoperatively and at the end-follow up. Preoperative and postoperative radiological measurements (trochlea depth, sulcus angle, patellar height, patellar congruence angle, patellar tilt angle and lateral patellofemoral angle) were evaluated with X-ray (Merchant X-ray, anteroposterior and lateral radiography) and computed tomography (CT) of the knee.
RESULTS
Postoperative patellar redislocation or subluxation was not observed in any patient. Patellar congruence angle, patellar tilt angle and lateral patellofemoral angle mean values were found to return to normal values in the postoperative period and the results were statistically significant. Also statistically significant improvement in all clinical scores postoperatively. According to the Insall-Salvati index (ISI) and Caton-Deschamps index (CDI) on lateral radiography of the knee at 30° flexion, patellar height decreased in the postoperative period statistically significant. The CDI was above 1.3 in 17 (%32) of our patients. Thirteen of these values decreased to normal values. No radiological progression of patellofemoral osteoarthritis was observed in all patients at the final follow-up evaluation.
CONCLUSION
In cases of patellofemoral instability, fixation of the tendon graft in blind ellipsoid tunnel using the Toggleloc suspension system provides satisfactory patellar graft fixation strength, significant functional improvement and a low failure rate.

Emergency surgeries are linked with increased morbidity and reduced life expectancy, often associated with low socioeconomic status, limited access to healthcare, and delayed hospital admissions. While the influence of socioeconomic status on elective surgery outcomes is well-established, its impact on emergency surgeries, including ostomy creation and closure, is less clear. This study aimed to explore how the pandemic and socioeconomic status affect emergency ostomy procedures, seeking to determine which has a greater effect. It emphasizes the importance of considering socioeconomic factors in patient care pathways for ostomy procedures. A total of 542 patients who underwent emergency ostomy formation between 2016 and 2022 were retrospectively analyzed and divided into pre-pandemic and pandemic periods. The pre-pandemic and pandemic periods were compared between themselves and against each other. Demographic data (age and sex), comorbidities, socioeconomic status, etiology of the primary disease, type of surgery, stoma type, length of hospital stay, ostomy closure time, and postoperative complications were retrospectively analyzed for all patients. In total, 290 (53%) patients underwent surgery during the pandemic period, whereas 252 (47%) underwent surgery during the pre-pandemic period. Emergency surgery was performed for malignancy in 366 (67%) patients. The number of days patients underwent ostomy closure was significantly higher in the low-income group (P = .038, 95% CI: 293,2, 386-945). The risk of failure of stoma closure was 3-fold (95% CI: 1.8-5.2) in patients with metastasis. The risk of mortality was 12.4-fold (95% CI: 6.5-23.7) when there was failure of stoma closure. When compared to pandemic period, the mortality risk was 6.3-fold (95% CI: 3.9-10.2) in pre-pandemic period. Pandemic patients had a shorter hospital stay than before the pandemic (P = .044). A high socioeconomic status was significantly associated with early hospital admission for ostomy closure, and lower probability of mortality. More metastases and perforations were observed during the pandemic period and mortality was increased during pandemic and in patients without ostomy closure. The socioeconomic status lost its effect in cases of emergency ostomy creation and had no impact on length of hospital stay in either the pre-pandemic or pandemic period.
