BACKGROUND/AIM: Extended total mesorectal excision (ETME) is defined as en bloc resection of the adjacent organs outside the mesorectal fascia, that is indicated in cases with locally advanced lower rectal cancer (T4 tumor). The aim of this study was to evaluate the clinical and oncological outcomes of laparoscopic ETME (L-ETME) for locally advanced lower rectal cancer. PATIENTS AND METHODS: The present study analyzed clinical outcomes and oncological outcomes of 11 consecutive patients who underwent L-ETME for cT4 lower rectal cancer in Nagasaki Medical Center between 2012 and 2015. RESULTS: Of the 11 patients, 7 underwent neoadjuvant therapy, and 7 underwent pelvic node dissection. One case (7.1%) underwent resection of anterior organs (prostate), 6 cases (54.5%) had resection of the lateral organs (neurovascular bundle, hypogastric nerve, pelvic plexus, ovary, and internal iliac blood vessels) and 4 cases (36.4%) had resection of both anterior and lateral organs. In all cases enrolled in this study, R0 resection was achieved. The median operation time and intraoperative blood loss were 416 min and 350 ml, respectively. The postoperative complication rate was 18.2% (2/11). The 3-year overall survival rate was 79.5%, and the 3-year local recurrence-free survival rate was 87.5%. There was no mortality and no re-operation in this series. CONCLUSION: The results of the present study suggest that L-ETME is feasible and has efficacy for locally advanced lower rectal cancer.
