Pancreatic tumor ablation is a novel and emerging treatment modality which can now be performed using endoscopic ultrasound (EUS) guidance. This modality is well suited to guide energy delivery for radiofrequency ablation (RFA) and microwave ablation. These approaches provide minimally invasive, nonsurgical methods for delivering energy to ablate pancreatic tumors in situ . This review summarizes the current data and safety profile for ablation in managing pancreatic cancer and pancreatic neuroendocrine tumors.Recent findings: RFA uses thermal energy to induce cell death by coagulative necrosis and protein denaturation. Studies have reported increased overall survival in patients with pancreatic tumors treated with EUS-guided RFA in a multimodality systemic approach and when used in palliative surgeries. Radiofrequency ablation may have corollary benefits in inducing an immune-modulatory effect. Tumor marker carbohydrate antigen 19-9 has been reported to decrease in response to RFA. Microwave ablation is an emerging modality.Summary: RFA utilizes focal thermal energy to induce cell death. RFA has been applied through open, laparoscopic, and radiographic modalities.

Historically, the treatment of benign strictures revolved around endoscopic balloon dilation, whereas, in the case of malignant strictures, the placement of self-expandable metallic stents was the focus. The advent of lumen-apposing metal stent has opened new horizons in addressing shortcomings of enteral stenting and surgical gastroenterostomies. The purpose of the review is to discuss the endoscopic approaches to small bowel strictures and to examine the supporting data behind each practice.Recent findings: Given the risk and futility of balloon dilation for malignant strictures, enteral stenting is pursued in patients who are poor surgical candidates and with life expectancy less than 6 months. For patients with longer survival, surgical gastroenterostomy (S-GE) should be considered. Recent data have shown comparable technical and clinical success rates between EUS-gastroenterostomy and S-GE but with lower adverse event rate and hospital length of stay.Summary: In recurrent benign strictures and malignant GOO, EUS-GE has recently gained momentum in providing an effective and a well tolerated alternative. Individualized therapy centered around the patient's prognosis and preference while factoring in the local expertise for the specific indication is vital.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":"39 5","pages":"356-361"},"PeriodicalIF":2.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9922306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we aim to provide the latest and relevant advances in AI, specifically deep learning (DL) and radiomics approaches, for pancreatic cancer diagnosis using cross-sectional imaging examinations such as computed tomography (CT) and magnetic resonance imaging (MRI).Recent findings: This review highlights the recent developments in DL techniques applied to medical imaging, including convolutional neural networks (CNNs), transformer-based models, and novel deep learning architectures that focus on multitype pancreatic lesions, multiorgan and multitumor segmentation, as well as incorporating auxiliary information. We also discuss advancements in radiomics, such as improved imaging feature extraction, optimized machine learning classifiers and integration with clinical data. Furthermore, we explore implementing AI-based clinical decision support systems for pancreatic cancer diagnosis using medical imaging in practical settings.Summary: Deep learning and radiomics with medical imaging have demonstrated strong potential to improve diagnostic accuracy of pancreatic cancer, facilitate personalized treatment planning, and identify prognostic and predictive biomarkers. However, challenges remain in translating research findings into clinical practice.

EPD classically results from conditions that cause loss of pancreatic acinar cell function and decreased digestive enzyme production. However, several conditions may contribute to signs or symptoms of EPD with otherwise normal pancreatic exocrine function. A thoughtful approach to considering these conditions, along with their specific therapies, can guide a tailored management approach.Recent findings: An EPD severity classification schema has been proposed, which emphasizes a shift towards a more restrictive prescription of pancreas enzyme replacement therapy (PERT) for patients with milder EPD. In contrast, PERT use has been associated with a measurable survival benefit among individuals with EPD and pancreatic cancer, so the prescription of PERT may be more liberal in this population. Recent publications in the cystic fibrosis population offer pearls guiding the titration and optimization of PERT.Summary: Among individuals with severe EPD, PERT is an effective therapy. Among individuals with milder EPD, although PERT is effective, there may be opportunities to provide additional and potentially more effective therapies.","PeriodicalId":50607,"journal":{"name":"Current Opinion in Gastroenterology","volume":"39 5","pages":"428-435"},"PeriodicalIF":2.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10403264/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9945543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
