However, physicians use CT-scan, X-rays, or MRI images to recognize bone cancer, but still require techniques to increase precision and reduce human labor. These methods face challenges such as high costs, time consumption, and the risk of misdiagnosis due to the complexity of bone tumor appearances. Therefore, it is essential to establish an automated system to detect healthy bones from cancerous ones. In this regard, Artificial intelligence, particularly deep learning, shows increased attention in the medical image analysis process. This research presents a new Golden Search Optimization along with Deep Learning Enabled Computer Aided Diagnosis for Bone Cancer Classification (GSODL-CADBCC) on X-ray images. The aim of the GSODL-CADBCC approach is to accurately distinguish the input X-ray images into healthy and cancerous. This research presents the GSODL-CADBCC technique that leverages the bilateral filtering technique to remove the noise. This method uses the SqueezeNet model to generate feature vectors, and the GSO algorithm efficiently selects the hyperparameters. Finally, the extracted features can be classified by improved cuckoo search with a long short-term memory model. The experimental results demonstrate that the GSODL- CADBCC approach attains highest performance with an average accuracy of 95.52% on the training set data and 94.79% on the testing set data. This automated approach not only reduces the need for manual interpretation but also minimizes the risk of diagnostic errors and provides a viable option for precise medical imaging-based bone cancer screening.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"94-108"},"PeriodicalIF":1.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate various technical factors which can influence ICG fluorescence intensity and thus interpretation of angiograms.MethodSingle institution retrospective study (2015-2021) of immediate implant-based breast reconstructions postmastectomy using a standardized technique of ICGA, controlling for modifiable factors of ambient lighting, camera distance and ICG dose. \"Time to perfusion\" assessment was defined as elapsed time from ICG administration to perfusion assessment. Intraoperative \"absolute\" and \"relative\" IGCA perfusion values of mastectomy flaps, taken at different time points (30, 60 and 90 seconds), were correlated with postoperative flap outcomes.ResultsThere were 260 breast reconstructions with a 3.1% necrosis rate. ICGA perfusion values, when measured at 60 and 90 seconds, were significantly lower for cases that developed necrosis compared to cases that did not, and were both good predictors of necrosis (area under ROC curves, 0.84 and 0.85, respectively). Fluorescence intensity increased as \"time to perfusion\" assessment increased for flaps that did not develop necrosis (correlation coefficient, 0.9, P < 0.001). Perfusion value cut-off thresholds for predicting necrosis were higher for a longer \"time to perfusion\" assessment.ConclusionsA standardized ICGA protocol is recommended as ICG fluorescence intensity increased with \"time to perfusion\" assessment, and ≤30 seconds did not allow for accurate perfusion analysis. Using a perfusion recording of 60 or 90 seconds, and the corresponding perfusion value cut-off, may optimize reliability of perfusion assessments.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"77-84"},"PeriodicalIF":1.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894893/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142932415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this procedure is associated with loss of beta cells after intrahepatic transplantation. Islet delivery devices (IDDs) implanted at extrahepatic sites may support engraftment and improve survival of pancreatic islets. We assessed the surgical feasibility, tolerability and safety of implantation of open microwell devices at subcutaneous sites with varying friction in pigs.MethodsOpen, non-immunoisolating microwell islet delivery devices were made from polyvinylidene fluoride (PVDF). Empty (n = 26) and islet-seeded devices (n = 8) were implanted subcutaneously in 6 immunocompetent pigs in low-friction sites (abdomen and lateral hip) and high-friction sites (anterior neck) for 3 months. Retrieved grafts were analyzed histologically with haematoxylin and eosin, and Masson's Trichrome staining.ResultsIslet-seeding and transportation of IDDs was free from complications with minimal islet spillage. IDDs were implanted subcutaneously using standard surgical equipment, without complications during the surgeries. IDDs implanted in the neck and IDDs co-transplanted with human islets were expelled and retrieved after 10 days. Empty IDDs were removed after 3 months. The abdominal site showed reduced signs of inflammation as compared to the neck region, while similar tissue ingrowth and vascularization of devices were found in the two locations.ConclusionsOpen microwell IDDs can safely be implanted with standard surgical equipment and successful islet-loading can be performed. Low-friction sites are preferable over high-friction sites for subcutaneous implantation in the porcine model since these lead to the least amount of foreign body reaction.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"141-148"},"PeriodicalIF":1.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894865/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142819249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients who underwent LSG were divided into two groups: one utilizing the NR and the other employing the VN for liver retraction. Parameters such as operation duration, retraction time, liver laceration, trocar-induced hemorrhage, subxiphoid trocar site infections, pain scores measured via the visual analog scale (VAS) at various time points, pre- and postoperative liver enzyme levels (AST, ALT, GGT, ALP) and CRP levels were analyzed.ResultsData from 151 patients were analyzed.

Virtual pointers, indicating the instructor's gaze through eye-tracking devices and overlaying it onto the screen using augmented reality (AR), can enhance understanding and reduce errors.Methods: In a study involving 10 participants divided into experts and novices in laparoscopic surgery, various pointers (differing in shape, size and colour) were analysed in an AR environment using the HoloLens2 device. The aim was to assess the acceptance of these pointers by both groups, understand how their characteristics affect perception, and evaluate the AR device's usefulness.Results: Initial results showed an 80% acceptance rate. After analysing the pointers, this decreased to 60%, as some experts changed their opinion from positive to neutral. The study revealed that the characteristics of the pointers significantly affect their perception, with large, thick-rimmed pointers being preferred. Orange was the best-performing colour. The device used also influenced perception, as experts who changed their perception criticised certain aspects of the head-mounted display.Conclusions: The study highlights the potential of virtual pointers to improve communication in laparoscopic training, particularly when their size, shape, and colour are optimised. Further research with a larger sample size is needed to confirm these results and explore the HoloLens2's influence on users' perceptions. These insights could guide the development of more effective training tools for minimally invasive surgery.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"54-61"},"PeriodicalIF":1.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
