PURPOSE: We present the preliminary experiences with and short-term outcomes of 50 consecutive patients with rectal cancer who underwent preoperative concurrent chemoradiotherapy (CCRT) followed by robotic surgery by using the high dissection and low ligation technique.
METHODS: Between October 2013 and August 2015, 50 patients with rectal cancer underwent robotic surgery after preoperative CCRT at a single institution. We performed D3 lymph node dissection and low tie ligation of the inferior mesenteric artery (IMA); this technique is referred to as the high dissection and low ligation technique. Clinicopathological features, perioperative parameters, and postoperative outcomes were retrospectively analyzed.
RESULTS: FOLFOX regimen was used for preoperative CCRT in 26 (52 %) patients. Long-course radiotherapy was concurrently administered. A pathological complete response (pCR) was obtained in 14 (28 %) patients. Of the 50 patients, 23 (46 %) patients received intersphincteric resection (ISR) with coloanal anastomosis, 25 (50 %) patients received lower anterior resection (LAR), and 2 (4 %) patients received abdominoperineal resection (APR). Apical nodes were pathologically harvested in 47 (94 %) patients, and the median number of harvested apical lymph nodes was 2 (range, 0-10). The overall complication rate was 24 % (10 patients with 12 episodes), and most complications were mild.
CONCLUSION: Roboic rectal surgery combined with appropriate preoperative CCRT helps in achieving a favorable pCR, circumferential resection margin, and sphincter preservation. Moreover, high dissection and low ligation of the IMA can be safely performed using the da Vinci(®) Surgical System safely which yield favorable short-term clinical outcomes.
