An appraisal of endoscopic removal of malignant XXXX .

@entity1 @entity1127 @entity2735 @entity5 @entity189 @entity3 @entity1586
The issue of whether @entity1 who have @entity189 in an otherwise benign polyp should undergo surgical resection of that bowel segment is controversial. We examined the records of 83 @entity1 with such @entity1127 that were removed endoscopically between 1978 and 1981. After exclusion of 18 @entity1 from the study for various reasons, our study group consisted of 65 @entity1 who had undergone complete endoscopic removal of 69 @entity1127 that contained a malignant process. @entity2735 was found in 34 @entity1127 , and 3 @entity1 with such @entity1127 had a recurrent malignant lesion of the same degree. These recurrent @entity5 were treated successfully by aggressive endoscopic removal. Seventeen @entity1127 that contained @entity189 were treated endoscopically without resection, and two @entity1 in this group subsequently had recurrent @entity189 at the site of the original polyp. These recurrent lesions were resected, and neither @entity1 had evidence of nodal @entity3 . Of the 18 @entity1 who underwent immediate resection of @entity189 , 2 had residual @entity189 at the time of the resection, although no lymph node @entity3 was found. We conclude that @entity1586 in situ can be treated safely with complete endoscopic removal. @entity189 in a polyp can be treated safely with complete polypectomy, and immediate resection may not be necessary. This group of @entity1 , however, should undergo thorough follow-up studies and periodic endoscopic reexamination.
