 To define the current management of colorectal carpet-like tumors, clinical data of 152 cases were accumulated from 11 centers and analysed.

 Endoscopic therapy was performed in 61 cases (40.1%) and surgical operation in 91 (59.9%). The average (±SD) maximal diameter of lesion in the former group was 22.48±11.30 mm, which was significantly smaller than that of the latter. In the former group, piecemeal polypectomy was generally employed for relatively large lesions, while strip biopsy was often selected for smaller ones. Local recurrence occurred in 6 (14.3%) out of 42 cases in which follow-up examination was made.

 Endoscopic therapy should not be selected for cancer invading beyond sm1. Therefore, precise diagnosis on the nature and depth of lesion is prerequisite to management decision. Indication of endoscopic treatment also depends on the skill of endoscopists. Whatever method one may choose, the procedure must be cautiously performed, since carpet-like tumors are often flat and large.
