Abstract

Background

Surgery is becoming less invasive as technology advances. Natural orifice specimen extraction surgery (NOSES) ushered in a new era of minimally invasive techniques. At the same time, NOSES is gaining popularity in the world. With their distinct advantages, surgical robots have advanced the development of NOSES. The aim of current study was to compare the short-term outcomes between robotic-assisted NOSES and laparoscopic-assisted NOSES for the treatment of middle rectal cancer.

Methods

Patients with middle rectal cancer who underwent robotic-assisted or laparoscopic-assisted NOSES at the First Affiliated Hospital of Nanchang University between January 2020 and June 2022 had their clinicopathological data collected retrospectively. 46 patients were enrolled in the study: 23 in the robotic group and 23 in the laparoscopic group. Short-term outcomes and postoperative anal function in the two groups were compared.

Results

There was no significant difference in the clinicopathological data between the two groups. The robotic group had less intraoperative blood loss (p = 0.04), less postoperative abdominal drainage (p = 0.02), lower postoperative white blood cell counts (p = 0.024) and C-reactive protein levels (p = 0.017), and shorter catheter removal time when compared to the laparoscopic group (p = 0.003). Furthermore, there were no significant difference in mean operative time (159 ± 31 min vs 172 ± 41 min) between the robotic and laparoscopic groups (p = 0.235), but time to naked the rectum (86.4 ± 20.9 min vs. 103.8 ± 31.5 min p = 0.033) and time of digestive tract reconstruction (15.6 ± 3.88 min vs. 22.1 ± 2.81 min p < 0.01) in the robotic group were significantly shorter than laparoscopic group. The robotic group had lower postoperative Wexner scores than the laparoscopic group.

Conclusions

This research reveals that combining a robotic surgical system and NOSES results in superior outcomes, with short-term outcomes preferable to laparoscopic-assisted NOSES.
