Despite the critical need for structured documentation, the current practice often relies on free-text recordings, which poses challenges for scalable intervention analysis; however, the introduction of large language models (LLMs) offers a promising solution by enabling the automatic extraction of adverse event details from procedural reports without altering existing documentation practices.</div></div><div><h3>Methods</h3><div>We analyzed 672 endoscopy reports, using OpenAI’s GPT-4 and Llama-2–based models to structure the data in JavaScript Object Notation for efficient analysis. We used an automated LLM pipeline to extract adverse events such as bleeding, perforation, and aspiration. The dataset was divided into a proof-of-concept set (PoC-S) with n = 171 reports, on which we explored prompt engineering to improve the performance of the models.

Conversely, Llama-2–based models, especially the Llama-2 variants fine-tuned for German language, demonstrated comparable performance (PoC-S: sensitivity of 94%; specificity of 92%, in the test set (TS): sensitivity of 89%; specificity of 93%) and offered a viable privacy-compliant alternative. The model effectiveness was further influenced by the method of prompt engineering, with experiments showing that the specificity and sensitivity could vary substantially based on the inclusion of specific prompt features, underscoring the importance of tailored prompt design.</div></div><div><h3>Conclusions</h3><div>Applying LLMs to extract structured medical information, particularly from endoscopy reports, offers an efficient, scalable, and adaptable documentation method that captures adverse events accurately with a low error rate.

Generally, a large defect is left that can increase the risk of postprocedural bleeding or perforation, and it has been managed by techniques such as endoscopic placement of clips to reapproximate the defect edges. An over-the-scope suturing system (OSS), OverStitch created by Apollo Endosurgery, has been designed for similar utility in ESD closure. The goal of its design is to achieve full-thickness closure and exchange of suture without endoscopic removal. The goal of this study was to evaluate the technical success and efficacy of using OSS in the closure of ESD.</div></div><div><h3>Methods</h3><div>A comprehensive literature review across multiple databases was performed. Studies including OverStitch and ESD information were evaluated, with 7 articles meeting predetermined eligibility of quality for inclusion. Statistical analysis was completed by using CMA version 3.0 software (Biostat, Englewood, NJ, USA). The primary evaluated end point was technical success and efficacy of instrument use in patients undergoing ESD closure with OSS. The secondary evaluated end point was the overall rate of adverse events related to the use of OSS.</div></div><div><h3>Results</h3><div>Overall, the pooled rates for instrumental efficacy and technical success were 95.8% (95% CI [confidence interval], 80.6%-99.2%; <em>P</em> = .04) and 99.2% (95% CI, 79.8%-100.0%; <em>P</em> = 1.00), respectively. The pooled rate of adverse events was .9% (95% CI, 0%-24.8%; <em>P</em> = .99) with pain reported as the most common adverse event.</div></div><div><h3>Conclusions</h3><div>OSS seems to be an effective and safe tool in the closure of defects after ESD. However, its design also makes it large and difficult to maneuver. Although it allows for replacement of the suture kit without endoscopic removal, there have been multiple reported episodes of device failure. Further randomized controlled trials are warranted as OSS becomes more widely used.</div></div>","PeriodicalId":100652,"journal":{"name":"iGIE","volume":"3 4","pages":"Pages 527-532.e2"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143139963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
