    Abstract:
    AIM: Comparison of transanal excision (TE) and transanal endoscopic microsurgery (TEM) of rectal adenomas (RA) has rarely been performed. METHOD: From 1990 to 2007, the results of TE (43 RA) and TEM (216 RA) were compared. Rectal adenomas were matched for diameter and distance from the anal verge. RESULTS: Operation time was 47.5 min for TE and 35 min for TEM (P < 0.001). Morbidity was 10% after TE and 5.3% after TEM (P < 0.001). Negative resection margins were observed in 50% after TE and 88% after TEM (P < 0.001). Fragmentation of the excised specimen was observed in 23.8% after TE and 1.4% after TEM (P < 0.001). In cases of fragmentation, positive resection margins were observed more frequently. Recurrence was 28.7% after TE and 6.1% after TEM (P < 0.001). After TE, RA with a negative resection margin had a local recurrence rate of 0%, compared with 59.6% with a positive margin (P < 0.001), and after TEM these rates were 3.2 and 7.7% (P = 0.3), respectively. CONCLUSION: Transanal endoscopic microsurgery is superior to transanal excision of RA.
