In children with drug-resistant epilepsy, the rate of freedom from seizures at 1 year was higher with epilepsy surgery than with medical therapy alone. Most measures of cognitive development were better in the surgery group than in the medical-therapy group.

Abstract A residual lung parenchyma abscess following pulmonary resection for lung cancer is a rare and potentially serious condition. We present a case of successful nonoperative management of a lung abscess that developed after a right upper lobectomy for adenocarcinoma in a 76-year-old man who experienced systemic symptoms 6 weeks after his initial surgery. Imaging revealed an abscess in the previous surgical cavity. We discuss management strategies and challenges associated with this uncommon condition.

The directions of distal and proximal airway stumps were different in Y-sleeve lobectomy. This difference might make Y-sleeve lobectomy a difficult procedure. In this article, we present our surgical techniques and analyse short-term outcomes of Y-sleeve lobectomy. Right middle and lower, left lower, and left lower and lingular segment sleeve lobectomies are categorized in Y-sleeve lobectomy. We retrospectively investigated the clinical courses of 17 patients who underwent Y-sleeve lobectomy from January 2017 to December 2020. No treatment-related deaths occurred. One patient developed a bronchopleural fistula. Four patients developed pneumonia and were cured by repeated bronchoscopies and antibiotic therapy. Three patients had retention of pleural effusion, and two had prolonged air leakage. One patient had empyema after prolonged air leakage and was cured by thoracic drainage and antibiotic therapy. A major complication was observed only in one patient. Y-sleeve lobectomy is a reliable surgical method to avoid pneumonectomy.

Background Robotic‐assisted thoracoscopic surgery (RATS) can achieve traditional clinical outcomes comparable to those of video‐assisted thoracoscopic surgery (VATS). However, patient‐reported outcomes (PROs) during the early period after RATS and VATS remain unclear. This study aimed to utilize longitudinal electronic PRO (ePRO) assessments to evaluate symptom burden and functional status between these approaches from patients' perspective. Methods This study comprised patients who underwent lobectomy via RATS or VATS for non‐small cell lung cancer. We collected multiple‐time‐point PROs data from the prospective longitudinal study via an ePRO system. Symptom severity and function status were assessed using the perioperative symptom assessment for patients undergoing lung surgery and were analyzed between groups using linear mixed‐effects models. Results Of the 164 patients, 42 underwent RATS and 122 underwent VATS. After propensity score matching (PSM), 42 RATS and 84 VATS exhibited similar baseline characteristics. During the 7‐day postoperative period, participants underwent RATS reported milder pain (p = 0.014), coughing (p < 0.001), drowsiness (p = 0.001), and distress (p = 0.045) compared with those underwent VATS. Moreover, participants in RATS group showed less functional interference with walking (p < 0.001) and general activity (p < 0.001). RATS exhibited a shorter postoperative hospitalization (p = 0.021) but higher hospital cost (p < 0.001). Meanwhile, short‐term clinical outcomes of operative time, dissected lymph node stations, chest tube drainage, and postoperative complication rates were comparable. Conclusion PROs are important metrics for assessing patients' recovery after lobectomy. Compared with VATS, RATS may induce less symptom burden and better functional status for patients in the early postoperative period. Key question: Are there any advantages of robotic‐assisted thoracoscopic surgery (RATS) compared to video‐assisted thoracoscopic surgery (VATS) from the patient's perspective? Key findings: Patients who underwent RATS lobectomy for lung cancer experienced less pain, coughing, drowsiness, and distress, as well as less impairment in walking and activity. Take‐home message: RATS lobectomy can achieve comparable traditional clinical outcomes to VATS. Notably, RATS yields milder symptoms and better functional status than VATS.

Background The effectiveness of robotic‐assisted lobectomy (RAL) for patients with non–small‐cell lung cancer (NSCLC) has not been fully evaluated. Methods This retrospective study compared the perioperative outcomes of NSCLC patients who underwent RAL and video‐assisted lobectomy (VAL) using propensity score matching (PSM) analysis. Subgroup analyses were then performed. Results A total of 822 NSCLC patients (359 RAL cases and 463 VAL cases) were included, and there were 292 patients in each group after PSM. Compared with the VAL group, the RAL group had a significantly higher number of lymph nodes (LNs) harvested (10 vs. 8, p < 0.001) and more LN stations examined (6 vs. 5, p < 0.001). The operative duration (95 minutes vs. 115 minutes, p < 0.001) and intraoperative estimated blood loss (65 mL vs. 80 mL, p < 0.001) were significantly reduced, and the drainage volume on postoperative day (POD) 1 (240 mL vs. 200 mL, p < 0.001) and hospitalization costs (¥81084.96 vs. ¥66142.55, p < 0.001) were significantly higher in the RAL group. Subgroup analysis indicated that the incidence of postoperative complications (17.9% vs. 26.7%, p = 0.042) was significantly reduced in the RAL group for overweight and obese patients (body mass index [BMI] ≥24 kg/m2), which became insignificant in the BMI < 24 kg/m2 subgroup (31.0% vs. 24.8%, p = 0.307). Conclusion RAL might have potential advantages in terms of lymph node assessment, reducing intraoperative blood loss, and shortening operation duration. Overweight and obese patients could benefit more from RAL because of reduced risk of postoperative complications. The incidence of overall postoperative complications (17.9% vs. 26.7%, p = 0.042) was significantly reduced in the robotic‐assisted lobectomy (RAL) group for overweight and obese patients (BMI ≥24 kg/m2), but there was no significant difference in the overall postoperative complications rate (31.0% vs. 24.8%, p = 0.307) between the RAL and video‐assisted lobectomy (VAL) groups in BMI <24 kg/m2 subgroup.

Background The discovery of cellular tumor networks in glioblastoma, with routes of malignant communication extending far beyond the detectable tumor margins, has highlighted the potential of supramarginal resection strategies. Retrospective data suggest that these approaches may improve long-term disease control. However, their application is limited by the proximity of critical brain regions and vasculature, posing challenges for validation in randomized trials. Anterior temporal lobectomy (ATL) is a standardized surgical procedure commonly performed in patients with pharmacoresistant temporal lobe epilepsy. Translating the ATL approach from epilepsy surgery to the neuro-oncological field may provide a model for investigating supramarginal resection in glioblastomas located in the anterior temporal lobe. Methods The ATLAS/NOA-29 trial is a prospective, multicenter, multinational, phase III randomized controlled trial designed to compare ATL with standard gross-total resection (GTR) in patients with newly-diagnosed anterior temporal lobe glioblastoma. The primary endpoint is overall survival (OS), with superiority defined by significant improvements in OS and non-inferiority in the co-primary endpoint, quality of life (QoL; “global health” domain of the European organization for research and treatment of cancer (EORTC) QLQ-C30 questionnaire). Secondary endpoints include progression-free survival (PFS), seizure outcomes, neurocognitive performance, and the longitudinal assessment of six selected domains from the EORTC QLQ-C30 and BN20 questionnaires. Randomization will be performed intraoperatively upon receipt of the fresh frozen section result. A total of 178 patients will be randomized in a 1:1 ratio over a 3-year recruitment period and followed-up for a minimum of 3 years. The trial will be supervised by a Data Safety Monitoring Board, with an interim safety analysis planned after the recruitment of the 57th patient to assess potential differences in modified Rankin Scale (mRS) scores between the treatment arms 6 months after resection. Assuming a median improvement in OS from 17 to 27.5 months, the trial is powered at > 80% to detect OS differences with a two-sided log-rank test at a 5% significance level. Discussion The ATLAS/NOA-29 trial aims to determine whether ATL provides superior outcomes at equal patients’ Qol compared to GTR in anterior temporal lobe glioblastoma, potentially establishing ATL as the surgical approach of choice for isolated temporal glioblastoma and redefining the standard of care for this patient population.

Background Only one prospective randomized study on the extent of mesial resection in surgery for temporal lobe epilepsy (TLE) exists. This randomized controlled trial (RCT) examines whether 3.5-cm mesial resection is leading to a better seizure outcome than a 2.5-cm resection. Methods Three epilepsy surgery centers using similar MRI protocols, neuropsychological tests, and resection types for TLE surgery included 207 patients in a RCT with pre- and postoperative volumetrics. One hundred and four patients were randomized into a 2.5-cm resection group and 103 patients into a 3.5-cm resection group, i.e., an intended minimum resection length of 25 versus 35 mm for the hippocampus and parahippocampus. Primary outcome measure was seizure freedom Engel class I throughout the first year. The study was powered to detect a 20% difference in class I outcome. Seizure outcome was available for 207 patients, complete volumetric results for 179 patients. Outcome analysis was restricted to control of successful randomization and an intent-to-treat analysis of seizure outcome. Results The mean true resection volumes were significantly different for the 2.5-cm and 3.5-cm resection groups; thus, the randomization was successful. Median resection volume in the 2.5-cm group was 72.86% of initial volume and 83.44% in the 3.5-cm group. At 1 year, seizure outcome Engel class I was 74% in the 2.5-cm and 72.8% in the 3.5-cm resection group. Conclusions The primary intent-to-treat analysis did not show a different seizure freedom rate for the more posteriorly reaching 3.5-cm resection group. It appears possible that not maximal volume resection but adequate volume resection leads to good seizure freedom.

Facial expressions of emotions have been shown to modulate early ERP components, in particular the N170. The underlying anatomical structure producing these early effects are unclear. In this study, we examined the N170 enhancement for fearful expressions in healthy controls as well as epileptic patients after unilateral left or right amygdala resection. We observed a greater N170 for fearful faces in healthy participants as well as in individuals with left amygdala resections. By contrast, the effect was not observed in patients who had undergone surgery in which the right amygdala had been removed. This result demonstrates that the amygdala produces an early brain response to fearful faces. This early response relies specifically on the right amygdala and occurs at around 170 ms. It is likely that such increases are due to a heightened response of the extrastriate cortex that occurs through rapid amygdalofugal projections to the visual areas.

BackgroundWith expanding neurosurgical options in epilepsy, it is important to characterise each options’ risk for postoperative cognitive decline. Here, we characterise how patients’ preoperative white matter (WM) networks relates to postoperative memory changes following different epilepsy surgeries.MethodsEighty-nine patients with temporal lobe epilepsy with T1-weighted and diffusion-weighted imaging as well as preoperative and postoperative verbal memory scores (prose recall) underwent either anterior temporal lobectomy (ATL: n=38) or stereotactic laser amygdalohippocampotomy (SLAH; n=51). We computed laterality indices (ie, asymmetry) for volume of the hippocampus and fractional anisotropy (FA) of two deep WM tracts (uncinate fasciculus (UF) and inferior longitudinal fasciculus (ILF)).ResultsPreoperatively, left-lateralised FA of the ILF was associated with higher prose recall (p<0.01). This pattern was not observed for the UF or hippocampus (ps>0.05). Postoperatively, right-lateralised FA of the UF was associated with less decline following left ATL (p<0.05) but not left SLAH (p>0.05), while right-lateralised hippocampal asymmetry was associated with less decline following both left ATL and SLAH (ps<0.05). After accounting for preoperative memory score, age of onset and hippocampal asymmetry, the association between UF and memory decline in left ATL remained significant (p<0.01).ConclusionsAsymmetry of the hippocampus is an important predictor of risk for memory decline following both surgeries. However, asymmetry of UF integrity, which is only severed during ATL, is an important predictor of memory decline after ATL only. As surgical procedures and pre-surgical mapping evolve, understanding the role of frontal-temporal WM in memory networks could help to guide more targeted surgical approaches to mitigate cognitive decline.

Background Data on high-flow nasal oxygen after thoracic surgery are limited and confined to the comparison with low-flow oxygen. Different from low-flow oxygen, Venturi masks provide higher gas flow at a predetermined fraction of inspired oxygen (FiO 2 ). We conducted a randomized trial to determine whether preemptive high-flow nasal oxygen reduces the incidence of postoperative hypoxemia after lung resection, as compared to Venturi mask oxygen therapy. Methods In this single-center, randomized trial conducted in a teaching hospital in Italy, consecutive adult patients undergoing thoracotomic lung resection, who were not on long-term oxygen therapy, were randomly assigned to receive high-flow nasal or Venturi mask oxygen after extubation continuously for two postoperative days. The primary outcome was the incidence of postoperative hypoxemia (i.e., ratio of the partial pressure of arterial oxygen to FiO 2 (PaO 2 /FiO 2 ) lower than 300 mmHg) within four postoperative days. Results Between September 2015 and April 2018, 96 patients were enrolled; 95 patients were analyzed (47 in high-flow group and 48 in Venturi mask group). In both groups, 38 patients (81% in the high-flow group and 79% in the Venturi mask group) developed postoperative hypoxemia, with an unadjusted odds ratio (OR) for the high-flow group of 1.11 [95% confidence interval (CI) 0.41–3] ( p  = 0.84). No inter-group differences were found in the degree of dyspnea nor in the proportion of patients needing oxygen therapy after treatment discontinuation (OR 1.34 [95% CI 0.60–3]), experiencing pulmonary complications (OR 1.29 [95% CI 0.51–3.25]) or requiring ventilatory support (OR 0.67 [95% CI 0.11–4.18]). Post hoc analyses revealed that PaO 2 /FiO 2 during the study was not different between groups ( p  = 0.92), but patients receiving high-flow nasal oxygen had lower arterial pressure of carbon dioxide, with a mean inter-group difference of 2 mmHg [95% CI 0.5–3.4] ( p  = 0.009), and were burdened by a lower risk of postoperative hypercapnia (adjusted OR 0.18 [95% CI 0.06–0.54], p  = 0.002). Conclusions When compared to Venturi mask after thoracotomic lung resection, preemptive high-flow nasal oxygen did not reduce the incidence of postoperative hypoxemia nor improved other analyzed outcomes. Further adequately powered investigations in this setting are warranted to establish whether high-flow nasal oxygen may yield clinical benefit on carbon dioxide clearance.
