Endoscopic examination carried out in 20,000 patients allowed 7 benign tumors of the oesophagus to be detected. Four of them were intramural tumors corresponding to leiomyomas. Guided biopsies are not sufficient to assure an accurate diagnosis, but a mucosal lesion, particularly a carcinoma, should be ruled out. Endoscopic resection of the 3 intraluminal tumours was performed without incidents, allowing an accurate histologic diagnosis and a reasonable therapeutic approach. Endoscopic supervision is necessary in case of epithelial tumors.
Endoscopic removal applies to sessile or pediculated gastroduodenal tumours of benign aspect, whose size is inferior to 2 cm. It is a fairly safe technique: accidents in 4.60/o cases and no death in these cases concerning 150 snare polypectomies. Endoscopic removal allows an accurate histological diagnosis and makes it possible to adopt a reasoned behaviour. An endoscopic control is necessary one month after the removal, and in case of adenomatous polyp an endoscopic examination is advisable every two years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
