Fig. 1 Perforations and leaks of the gastrointestinal (GI) tract. Perforations, leaks, and fistulae of the GI tract may occur as a result of surgery, ingestion of foreign bodies, retching, trauma, inflammatory and neoplastic conditions, and as a complication from diagnostic and interventional endoscopy. The graphic shows common areas of luminal GI damage such as esophageal perforation, dehiscence of anastomosis after surgery, duodenal perforation during endoscopic retrograde cholangiopancreatography or endoscopic ultrasound, and colonic leaks and perforations. The therapeutic endoscopist should be able to manage most of these discontinuities of the luminal GI tract with various devices such as those as shown on figures.

Fig. 3 Endoscopic views showing: a a target sign indicating excisional injury to the muscularis propria (after each snare resection and at the completion of the procedure, the endoscopic mucosal resection (EMR) defect should be inspected for signs of deep mural injury); b,c clip closure of the injury to the muscularis propria (the entire defect does not need to be closed but there should be firm closure of the muscle injury); d – f the use of coagulating forceps to control bleeding (significant post-EMR bleeding occurs in 5%– 7% of patients, with approximately two-thirds settling spontaneously without the need for further endoscopy, while endoscopic hemostasis is readily achieved in those that continue to bleed).
