Digestive endoscopy has evolved from primary diagnosis to extensive therapeutic approaches for the management of gastrointestinal diseases. Increased health awareness has encouraged more people to undergo endoscopic examinations. For these reasons, the absolute number of iatrogenic perforations is likely to increase. Because of the very low incidence of perforations, clinicians are not always prepared or experienced in cases of unexpectedly encountered perforations during diagnostic or therapeutic endoscopic procedures. In this study, the proper approach to handling perforations is discussed including selection of endoscopic devices, endoscopic closure procedures, and management of patients after a perforation occurs in the gastrointestinal tract.

Because gastrointestinal (GI) endoscopy examinations are being performed increasingly frequently, the rate of detection of cancer and of precancerous lesions has increased. Moreover, development of more advanced endoscopic technologies has expanded the indications for, and thus frequency of, therapeutic endoscopic procedures. However, the incidence of complications associated with diagnostic or therapeutic GI endoscopy has also increased. The complications associated with GI endoscopy can be ameliorated by endoscopic or conservative treatment, but caution is needed as some of the more serious complications, such as perforation, can lead to death. In this chapter, we review the possible complications of GI endoscopy and discuss methods for their prevention and treatment.

Colonoscopy offers higher diagnostic sensitivity than other colorectal cancer screening methods and provides the advantage of both diagnostic tissue sampling and polyp removal. Since the majority of colorectal cancers evolve from adenomatous polyps, polyp resection through colonoscopy is widely considered an effective method of preventing colorectal cancer and reducing mortality rates.Current Concepts: Determining colorectal polyp size and shape requires comprehensive endoscopy with enhanced imaging techniques to choose treatment directions and the appropriate colorectal polypectomy method. The selection of the polypectomy method is contingent upon the polyp’s attributes and possible malignancy according to US Multi-Society Task Force on Colorectal Cancer and European gastrointestinal endoscopy guidelines. This article examines eight polypectomy procedures: cold forceps polypectomy, hot biopsy polypectomy, cold snare polypectomy, hot snare polypectomy, endoscopic mucosal resection (EMR), and modified EMR techniques. Each method has unique benefits and is suitable for particular polyp types and sizes. Piecemeal EMR and endoscopic submucosal dissection offer alternatives for larger or challenging lesions that require careful planning and follow-up. After endoscopic resection of early colorectal cancer, further surgery may be necessary depending on the risk of lymph node metastasis as determined by specific histologic findings following Korean and Japanese guidelines.Discussion and Conclusion: The choice of endoscopic resection technique, which depends on factors such as polyp shape, size, and location as well as endoscopist skill, is crucial for ensuring complete polyp removal.
