【Abstract】 Objective To investigate the characteristics of adenomatous polyp with malignant transformation, the indications for local resection, and the advantages of local resection by kraske’s operation with posterior approach. Methods A retrospective analysis the five year’s clinical material (1995～1999) and operative effect in 18 patients of adenomatous polyp with malignant transformation in rectum within 5～15cm from anus, was peyored. Results Among fourteen patients treating with local resection through anus, two had local recurrence within 8～12 months after operation. Up to now, however, no one has local recurrence among 4 locally resection cases who were treating by krask’s operation with posterior approach. Conclusions The indications for local resection of adenomatous polyp with malignant transformation in rectum are that the malignant polyp was restrected in mucous membrance. Comparing with local resection through anus in treating adenomatous polyp with malignant transformation in middle and low segments of rectum, the local resction by kraske’s operation with posterior approach were less injury, better visibility and more easy in operation, and the focus can be cleared thoroughly. Hence, it deserves to be populariced.更多还原
