Laparoscopic Low Anterior Resection of the Rectum with Transanal Prolapsing Specimen Extraction: Early Experience with 23 Patients

Abstract Objective: For laparoscopic low anterior resection of the rectum, a small additional incision is needed to extract the specimen. We describe an adjustment technique, which inserted the anvil and extracted the specimen through transanal pathway. Methods: Between July 2010 and July 2012, 23 patients underwent laparoscopic rectal surgery with transanal anvil insertion and transanal prolapsing specimen extraction. All perioperative data and short-term outcomes were recorded in a database. Results: The mean patient age was 61.3 years (range 47–68 years). Of the 23 patients, 17 underwent resection for rectal carcinoma and 6 had tubulovillous adenomas. No intraoperative complications occurred. The mean operative time was 137 minutes (range 118–170 minutes). The distal margins, circumferential resection margins, and lymph node dissections were oncologically adequate for all malignancies. One patient experienced anastomotic leakage (4.3%), treated conservatively. One male patient with benign prostatic hyp...
