Current status of robotic surgery for rectal cancer: A bird's eye view.

The MRC CLASICC trial showed a trend towards increased sexual dysfunction in the laparoscopic arm in comparison to the open group.[ 1 ] Comparison of robotic and laparoscopic groups in the study by Kim et al .[ 21 ] showed decreased sexual desire and voiding function in both groups 1 month after surgery with more rapid and complete recovery of both parameters in the robotic group; possibly due to a more delicate operation with the robotic apparatus.

There were however concerns raised due to a higher conversion rate and a trend towards a higher Circumferential Margin Positivity [CRM] rate in the laparoscopic arm [ Table 1 ].[ 1 ] The CRM positivity however did not reach statistical significance and indeed did not worsen survival on long-term analysis.
