RESUMO
Endoscopic resection is currently accepted as a standard therapy for colon polyp because of its safety and efficiency. The indications for endoscopic resection have been expanded to treat mucosal colon cancer and submucosal tumor. The major complications of endoscopic resection are hemorrhage, perforation and post- polypectomy coagulation syndrome. Hemorrhage is the most common complication, and this can occur immediately following colonoscopic polypectomy or it can be delayed after completion of the procedure. Delayed hemorrhage usually occurs within 7 days and this can stop by itself or the hemorrhage can be controlled endoscopically in the majority of patients, with only the unusual and serious cases requiring transfusion, angiography and surgery. We experienced a case of delayed massive hemorrhage with hypotension that required transfusion 12 days after performing endoscopic resection for rectal carcinoid tumor. We report here on this case to provide a good example and to place emphasis on delayed massive hemorrhage after endoscopic resection.
