The CUSUM curve shows three phases in the learning and use of robotic assisted rectal cancer surgery which correspond to the phases of initial learning of the technique, consolidation and higher expertise or mastery. The data obtained suggest that the estimated learning curve for robotic assisted rectal cancer surgery is achieved after 21-23 cases.

Robotic advantages could have an impact on learning curve for rectal cancer and lower the number of cases that are necessary for rectal resections.

VAC therapy is an alternative to surgery that can be safely administered in an ambulatory setting. Early administration in the 6 weeks following surgery is an independent predictive factor for successful closure; however, colonic transit was only recovered in a small percentage of patients.
