Abstract Accurate and robust navigation in complex surgical environments is crucial for bronchoscopic surgeries. This study purposes a bronchoscopic lumen feature matching network (BLFM-Net) based on deep learning to address the challenges of image noise, anatomical complexity, and the stringent real-time requirements. The BLFM-Net enhances bronchoscopic image processing by integrating several functional modules. The FFA-Net preprocessing module mitigates image fogging and improves visual clarity for subsequent processing. The feature extraction module derives multi-dimensional features, such as centroids, area, and shape descriptors, from dehazed images. The Faster R-CNN Object detection module detects bronchial regions of interest and… More >

Abstract Objective: Many children with fully corrected congenital heart disease (CHD) avoid physical activity (PA). This descriptive study sought to determine child and parental factors that could predict PA levels in Thai children after corrective surgery. Methods: Ninety school-aged children with fully corrected CHD were recruited from a cardiology clinic at a university hospital in northern Thailand. Data collection involved five validated questionnaires: (1) the Modified Thai Adolescent’s Physical Activity Questionnaire, (2) the Child Health Status Questionnaire-Forms I and II, (3) the Parental Knowledge on School-aged Children’s Physical Activity Scale, (4) the Perceived Self-efficacy to Physical Activity… More >

Abstract Introduction: Surgeons typically prefer 270 µm and 272 µm laser probes in retrograde intrarenal surgery (RIRS) due to the reduced deflection capacity of flexible ureterorenoscopes when using larger probe diameters. This study aims to investigate the effects of 272 and 365 µm holmium laser probes on operative time, clinical efficacy, and complication rates in RIRS. Materials and Methods: A total of 285 patients with proximal ureteral or kidney stones who met the inclusion criteria were enrolled in the study. Patients were divided into two groups based on laser probe thickness: 272 µm and 365 µm. Stone-free… More >

Abstract Background: Small cell lung cancer (SCLC) is characterized by its aggressive nature and high propensity for brain metastases. This study investigates the clinical efficacy and safety profile of Anlotinib in combination with Stereotactic Radiotherapy (SRT) for treating brain metastases in patients with small cell lung cancer (SCLC). Methods: This research included 98 SCLC brain metastasis patients treated at Chengde Central Hospital from October 2020 to January 2024. The patients were categorized into a combined treatment group (CTG) (n = 45) and a Simple SRT group (SSG)(n = 53). The CTG (58 lesions) received Anlotinib with… More >

Abstract Aorta–right atrial tunnel (ARAT) is an extremely rare congenital heart malformation with an average age of diagnosis of approximately 20 years. Its clinical symptoms are varied and often atypical. ARAT usually originates from the left or right sinus of Valsalva. In this case report, we aim to share a rare case of ARAT originating from the noncoronary sinus in an infant. The patient presented with a cardiac murmur, a dilated right heart, and a tortuous tunnel originating from the dilated noncoronary sinus and terminating at the right atrium in echocardiogram and computed tomography angiography.

Abstract Background: Congenital cardiac diseases (CCD) are common congenital birth defects that require high-risk surgery. Outcomes following congenital cardiac surgery in children living in high-income countries (HIC) have been documented, but little is known from the African continent. This study aimed to determine factors associated with perioperative mortality in patients who underwent congenital cardiac surgery at our institution. Methods: This retrospective, cross-sectional study was conducted at Charlotte Maxeke Johannesburg Academic Hospital over 12 years (2006–2017). A multivariable regression analysis was performed for the factors which had a p-value of 0.1 and less in the univariable regression analysis. A… More >

Abstract Introduction: Gender affirming surgeries (GAS), such as phalloplasty (PLPs) and vaginoplasty (VGPs), are important aspects of medical care for transgender patients. Here, we aim to better characterize patient demographics and surgical outcomes for PLPs and VGPs using the National Surgical Quality Improvement Program (NSQIP). We hypothesized that frailty indices would be predictive of perioperative PLP and VGP risk and outcomes for PLPs and VGPs.
Materials and methods: Primary GAS, specifically PLPs and VGPs performed from 2006-2020 were identified in NSQIP. Baseline frailty was based on NSQIP’s modified frailty index (mFI) and preoperative morbidity probability (morbprob) variable.
Results: Fifty-eight… More >

Abstract The Hem-o-lok Weck clip is part of a polymer locking ligation system often employed for hemostasis in surgical practices. Its use is routine in a wide array of surgical subspecialties. Surgeons have limited options in removing these clips when they are aberrantly positioned.
Herein, we describe a novel, cost-effective approach for removing a Hem-o-lok clip using standard robotic instruments. This simple approach will allow surgeons to remove a Hem-o-lok clip precisely and quickly if it is not adequately placed.
During a routine robotic-assisted laparoscopic prostatectomy a Hem-o-lok Weck clip was noted to be in juxtaposition to… More >

Abstract Introduction: The evidence on the effectiveness of prehabilitation in patients undergoing bladder cancer surgery remains lacking. Thus, the aim of this study is to determine the effectiveness of prehabilitation on reducing postoperative morbidity and length of hospital stay in patients undergoing bladder cancer surgery.
Materials and methods: This systematic review included randomized controlled trials investigating the effect of prehabilitation on postoperative outcomes in patients undergoing bladder cancer surgery. A comprehensive search was conducted, with two reviewers independently screening articles and extracting data. The Cochrane Collaboration’s tool was used to assess risk of bias, and GRADE to rate… More >
