Escisión mesorrectal total laparoscópica versus asistida por robot en el tratamiento del cáncer de recto: un metaanálisis

Five trials with a total of 380 patients were selected, of whom 169 were subjected to RA-TME and 211 to L-TME. No significant differences were found, although RA-TME was associated with a lower conversion rate, a greater resection margin circumference, and higher number of isolated lymph nodes, as well as a lower overall rate of complications. There was no evidence that RA-TME had advantages that compensated for the longer duration of the surgery and the higher cost of the procedure. More randomised prospective studies and a greater number of patients are needed.
