Comparison of the short‐term operative, Oncological, and Functional Outcomes between two types of robot‐assisted total mesorectal excision for rectal cancer: Da Vinci versus Micro Hand S surgical robot

Abstract Objective This study aimed to evaluate the difference of two various robotic technology applied in R‐ Total mesorectal excision (TME). Methods From May 2017 to December 2018, consecutive patients with rectal cancer who underwent da Vinci R‐TME or Micro Hand S R‐TME were enrolled. The comparative study was conducted on Short‐term Operative, Oncological, and Functional Outcomes between two type of R‐TME. Results 47 patients underwent da Vinci R‐TME, and 43 patients underwent Micro Hand S R‐TME. No difference occured between two groups in TME completeness, CRM, DRM, CRM involvement and DRM involvement, operative time, blood loss, protective ileostomy, conversion rate, number of retrieved lymph nodes, Comprehensive Complication Index (CCI), International Prostate Symptom Score (IPSS) or Wexner scores. However, the setup time in the Micro Hand S group was longer. Conclusions In the present study, both da Vinci R‐TME and Micro Hand S R‐TME achieve excellent TME quality with acceptable morbidity and postoperative function.
