715 Background: Complete mesocolic excision (CME) with central vascular ligation (CVL) has been advocated for right colon cancer (RC), but the radicality of lymphadenectomy remains controversial. Optimal D2 lymphadenectomy removes all intermediate nodes with high ligation (HL) of feeding vessels, while D3 lymphadenectomy additionally exposes and retrieves nodes along ventral superior mesenteric vessels (SMA/V). We aim to evaluate minimally invasive CME-CVL, explicitly defining the radicality of central lymphadenectomy. Methods: Patients who underwent minimally invasive resection for RC between 2008 and 2016 were identified from a prospective institutional database. CME was standard. The radicality of central lymphadenectomy was defined as high ligation (HL, optimal D2) vs central node dissection (CND, D3) after review of operative reports and/or videos. A blinded radiologist evaluated the pre- and post-operative CT scans for radiographically abnormal nodes. Results: Among 200 patients, 169 (84.5%) underwent laparoscopic and 31 (15.5%) robotic resection. Central lymphadenectomy was performed as HL in 58 (29%) and as CND in 142 (71%) patients. Preoperative imaging identified abnormal D2 nodes in 33.0% and D3 nodes in 2.6%. CND was performed in 73% of those with abnormal D2 and 100% of those with abnormal D3 nodes. Pathologically positive nodes were identified in 41% (37.9% of the HL and 42.3% of the CND, p=0.64). The median number of nodes retrieved was 27 and 32, respectively. No patient had residual abnormal node on post-operative imaging. The 30 day mortality rate was 0%, and morbidity rate was 15% (4% grade 3, 11% grades 1-2). After a median of 22 months, one (0.5%) patient recurred locally at the anastomosis. Conclusions: Minimally invasive CME-CVL can be safely performed with excellent nodal yield with both optimal D2 as well as D3 lymphadenectomy. With imperfect clinical nodal staging, the near-zero local recurrence rate observed supports CME with optimal D2 lymphadenectomy as a minimum standard and D3 lymphadenectomy when radiographically abnormal nodes are identified.

Abstract Background Minimally invasive colorectal surgery has demonstrated to have the same oncological results as open surgery, with better clinical outcomes. Robotic assistance is an evolution of minimally invasive technique. Purpose The study aims to present technical details and short-term oncological outcomes of robotic-assisted complete mesocolic excision (CME) with central vascular ligation (CVL) for right colon cancer. Methodology Fifty-two consecutive patients affected by right colon cancer were operated between May 2016 and February 2020 with da Vinci Xi platform. Data regarding surgical and short-term oncological outcomes were systematically collected in a colorectal specific database for statistical analysis. Results Thirty-seven (71.15%) and 15 (28.85%) patients underwent right and extended right hemicoletomy with an extracorporeal anastomosis. Median age was 55 years. Mean operative time was 182 ± 36 min. Mean blood loss was 110 ± 90 ml. Conversion rate was 3.84% (two cases). 78.84% (41 cases) were pT3 and mean number of harvested lymph nodes was 28 ± 4. 1/52 (1.92%) had a documented anastomotic leak requiring exploratory laparotomy and diversion proximal ileostomy. Surgery-related grade IIIa–IIIb Calvien Dindo morbidity were noted in 9.61% and 1.92%, respectively. Conclusion Robotic assistance allows performance of oncological adequate dissection of the right colon with radical lymphadenectomy as in open surgery, confirming the safety and oncological adequacy of this technique, with acceptable results and short-term outcomes.
