title: [Local excision of giant rectal polypoid neoplasms].
abstract: Local excision is the best therapeutic option for giant adenomas of the rectum. Parks technique for lower rectal lesions and the T.E.M. technique for lesions localised in the middle and upper rectum offer exceptionally good exposure, allowing radical excision in the case of early low-risk T1 adenocarcinomas (well or moderately differentiated [G1/2] without lymphovascular invasion [L0]). From July 1987 to March 2006, 224 patients were treated by local excision for rectal lesions in our department. In 48 patients (21.4%) a large sessile benign lesion was diagnosed preoperatively. In 3 patients with a preoperative diagnosis of severe dysplasia (Tis) final pathology showed adenoma and for this reason they were included in our study group. A total of 51 patients with giant preoperative benign lesions were treated by local excision (Parks technique, T.E.M. or both). Twenty-five (49%) patients had a definitive diagnosis of adenocarcinoma: in situ (pTis) in 22 patients (88%), pT1 in 2 patients (8%) and pT2 in 1 patient (4%). In 26 patients (51%) the diagnosis was adenoma. The overall local recurrence rate was 9.8% (5/51); the recurrence rate was 7.6% (2/26) for adenomas and 12% (3/25) for carcinomas. The median hospital stay was 7 days (range 3-39). There was no operative mortality. Giant sessile polypoid lesions localized in the middle and upper rectum are best treated with T.E.M., while Parks technique is a good option in lower rectal tumours. These techniques, if correctly indicated and well performed, offer great advantages in terms of safety and radicality. In our experience the operative mortality was nil and the morbidity and recurrence rates were low.
