PURPOSE: It is generally recommended that the defect, after full thickness total wall excision of a tumour located in the extraperitoneal part of the rectum, should be sutured. There is a lack of controlled studies however, supporting this approach. The aim of this study was to compare the results obtained in patients after peranal local excision of rectal tumours whose defect were sutured with those that were not. METHODS:44 patients were prospectively randomized to group A: The defect is closed; Group B: Defect left un-sutured. Pre-operative test were digital examination, proctoscopy and endorectal ultrasound. Local full-thickness excision was performed mainly with the Transanal Endoscopic Microsurgery (TEM) equipment, but for cases near the anal verge a Parks' retractor was used. Data recorded were operation time, blood loss, hospital stay and early and late complications. The first postoperative assessment was planned at 1 month and then every three months until 18 months of follow-up. Result for 40 patients (21 from group A; 19 from group B) were analysed. There were no differences between groups regarding age, sex, location of the tumour and specimen's size. RESULTS: The intra-operative loss of blood was 22 ml for group A and 39 ml for B, the difference was not significant. The mean operation time was slighter longer for group A (93 min) than for group B (77 min) but not statistically significant. For both group the mean hospital stay was of 4[2-7] days. No differences in early or late complications could be demonstrated. CONCLUSION: The present study suggests that there is no difference between these two practices in terms of intra-operative results and outcome.
