Local excision of selected rectal cancers is an acceptable alternative to radical surgery. The results of local excision of various rectal lesions using either the transanal or trans-sacral approach were reviewed over a 10-year period at this institution. A total of 56 procedures were performed on 47 patients (50 transanal/six trans-sacral). The trans-sacral approach was used six times on five patients for lesions averaging a distance of 8 cm from the anal verge. The transanal approach was used 50 times on two patients for lesions occurring at an average distance of 5 cm from the anal verge. Twenty-six malignant lesions were excised (25 transanal/one trans-sacral) with pathologies ranging from poorly to well-differentiated adenocarcinoma. Staging included 12 T[sub 1] lesions (46%), 10 T2 lesions (38%), and four T[sub 3] lesions (16%). Eighteen malignancies were completely excised and recurrence occurred in four of 18 (22%) with an average follow-up of 2.3 years (range 0-10 years). Local recurrence occurred in two patients (T[sub 1] and T[sub 2] lesions) and recurrence was in the form of distant metastasis in two patients (two T[sub 3] lesions). Three of the recurrences occurred in patients with T[sub 3] lesions (three of four; 75%), two occurred in a patient with a T[sub 2] lesion (two of 10; 20%), and one occurred in a patient with a T[sub 1] lesion (one of 12; 8%). There were no cancer-related deaths during the study period. Twenty-six premalignant lesions (adenomatous polyps) and four benign lesions were excised (25 transanal/five trans-sacral). Local recurrence occurred 10 times with an average follow-up of 1.8 years. In conclusion local excision of certain rectal cancers is an acceptable alternative in the treatment of these malignancies.
