Robotic TME is oncologically safe and adequate for rectal cancer treatment, showing better results than laparoscopic TME in terms of CRM, conversions, and hospital length of stay. Better recovery in voiding and sexual function is achieved with the robotic technique.

After local excision of early rectal cancer, a substantial local recurrence rate is observed. Patients with recurrent Tis/T1 cancers who undergo a salvage operation may achieve good long-term outcome. Local treatment without adjuvant therapy for T2 rectal cancers appears inadequate.

Robotic assistance allows performance of oncologically adequate dissection of the right colon with radical lymphadenectomy and to fashion a handsewn intracorporeal anastomosis as in open surgery, confirming the safety and oncological adequacy of this technique, with acceptable results and short-term outcomes.

Thanks to robotic technology, some subpopulations of patients with clinical or oncological contra-indications to laparoscopic treatment may be addressed with minimally invasive treatment.

Background. Colorectal cancer is the fourth leading cause of death in the world. Minimally invasive surgery has been demonstrated to have the same oncological results as open surgery, with better clinical outcomes. Robotic assistance is an evolution of minimally invasive technique. This study aims to evaluate surgical and oncological short-term outcomes of robotic-assisted right colon resection in malignant disease. Methods. Fifty consecutive patients affected by rightsided colon cancer were operated from May 2001 to May 2009 using the da Vinci Ò surgical system. Data regarding surgical and early oncological outcomes were systematically collected in a specific database for statistical analysis. Results. Twenty-four male and 26 female patients underwent robotic right colectomy. Median age was 73.34 ± 11 years. Median operative time was 223.50 (180-270) min. No conversion occurred. Specimen length was 26.7 ± 8 cm (range 21-50 cm), number of harvested lymph nodes was 18.76 ± 7.2 (range 12-44), and mean number of positive lymph nodes was 1.65 ± 3 (range 0-17). Surgeryrelated morbidity was 1/50 (2%): one twisting of the mesentery in one case with extracorporeal anastomosis. All patients were included in a follow-up regimen. Diseasefree survival was 90% (45/50), and overall survival was 92% (46/50). Cancer-related mortality was 8% (4/50). Conclusions. Robotic assistance allows performance of oncologically adequate dissection of the right colon with radical lymphadenectomy and to fashion a handsewn intracorporeal anastomosis as in open surgery, confirming the safety and oncological adequacy of this technique, with acceptable results and short-term outcomes.
