It is commonly believed that traditional endoscopy has reached its limits due to the intrinsic characteristics of existing platforms. Numerous robotic endoluminal platforms have been developed to overcome limitations in recent years. Existing robotic endoluminal platforms can be divided into three categories: fully robotic flexible endoscopic, robotic add-on systems, and traditional surgery-based platforms. These platforms are incredible pieces of technology, but in reality, they can only be considered a bridge to a genuinely robotic surgical system. Nowadays, both gastroenterologists and surgeons perform endoscopic procedures all over the world. We believe these platforms, leading to increased manipulation possibilities, may require an increasingly excellent knowledge of surgical techniques to develop their potential fully. Surgeons' unique training and experience push surgeons to take the lead in endoscopic operations over gastroenterologists due to the potential advantages in surgical precision and patient outcomes. However, gastroenterologists deeply understand gastrointestinal disorders and a collaborative effort between them and surgeons can lead to an efficient approach to endoscopic surgery.</p></div>","PeriodicalId":55956,"journal":{"name":"Seminars in Colon and Rectal Surgery","volume":"35 2","pages":"Article 101025"},"PeriodicalIF":0.3,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1043148924000241/pdfft?md5=1c7c82c30dfcb4e5d5dfe60fb76cba8e&pid=1-s2.0-S1043148924000241-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141026767","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}

As the number of colonoscopies performed increases, the detection of advanced and difficult to resect polyps will also rise. These polyps tend to be larger, greater than 2 cm, have flat morphology, and are in difficult anatomic locations behind haustral folds or at sharp flexures of the colon. Advanced endoscopic techniques such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are useful to remove these polyps. However, many polyps remain unresectable with these techniques. Combined endoscopic laparoscopic surgery (CELS) has shown to be an effective technique to facilitate safe removal of complex polyps. CELS encompasses a variety of techniques including laparoscopic assisted ESD/EMR and laparo-endoscopic full thickness excisions (FLEX). Success rate of CELS ranges from 70 to 100 %, with less than 5 % conversion to colectomy. Perioperative outcomes boast shorter hospital length of stay, with low rates of serious post-op complications when compared to colectomy. Malignancy rate after CELS in appropriately selected patients is low, ranging from 1.6 %-10 % of cases. Polyp recurrence rate after CELS is also low, usually less than 10 %. Use of CELS for early-stage cancers remains controversial but maybe adequate in appropriately selected patients. Further evaluation and long-term studies are needed to study its efficacy in cases of known cancer. The purpose of this review is to provide recommendations for use of CELS techniques, appropriate indications, describe technical tips, and review potential future applications.</p></div>","PeriodicalId":55956,"journal":{"name":"Seminars in Colon and Rectal Surgery","volume":"35 2","pages":"Article 101022"},"PeriodicalIF":0.3,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141027853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
