title: Management of large malignant rectal polyps with transanal endoscopic microsurgery. Is there anything better for the patient?
abstract: The authors report their experience with transanal endoscopic microsurgery (TEM), a technique that allows all the standard surgical manoeuvres such as tissue excision, suction, control of bleeding and suturing in the entire length of the rectal cavity. Main indications for TEM are the removal of large sessile polyps and early rectal cancers' (T1, G1-G2). Out of 50 patients submitted to TEM the authors consider in this study 24 cases with a preoperative diagnosis of benign large sessile polyps. The procedures included: 14 (58.3%) total wall excision, four (16.6%) total wall excision with perirectal fat, three (12.5%) mucosectomy, one mucosectomy + total wall excision, one partial wall excision + total wall excision, and the remaining case was converted to laparotomy due to a large intraperitoneal perforation. There was no operative mortality and an 8.3% rate of major complications. With a median follow up of 19 months there was no evidence of local or distant recurrence. The authors compare their results with those of alternative endoscopic and surgical techniques and highlight the advantages of TEM in the management of large and giant rectal polyps.
