Abstract 434

Background

Robotic rectal cancer surgery is gaining popularity, however, the scientific basis for treatment of rectal cancer is still unclear.

Methods

The cases of robot-assisted or laparoscopic colorectal resection were collected retrospectively between July 2015 and October 2017. We evaluated patient demographics, perioperative characteristics, and pathologic examination. A multivariable linear regression model was used to assess short-term outcomes between robotassisted and laparoscopic surgery. Short-term outcomes included time to passage of flatus, and postoperative hospital stay.

Results

A total of 284 patients were included in the study. There were 104 patients in the robotic colorectal surgery (RCS) group and 180 in the laparoscopic colorectal surgery (LCS) group. The mean age was 60.5 ± 10.8 years, and 62.0% of the patients were male. After controlling for confounding factors, the multiple linear model regression indicated that time to passage of flatus in the RCS group was 3.45 days shorter than the LCS group (Coef=-3.45; 95% CI, -5.19 to -1.71; P < 0.001). Additionally, the drainage of tube duration (Coef=0.59, 95% CI 0.3 to 0.87; P < 0.001) and transfers to the intensive care unit (Coef=7.34, 95% CI 3.17 to 11.5; P = 0.001) influenced the postoperative hospital stay. The total costs increased by 15501.48 CNY in the RCS group compared to the LCS group (P = 0.008).

Conclusions

The present study suggests that colorectal cancer robotic surgery was more beneficial to patients because of shorter postoperative recovery time of bowel function and shorter hospital stays.
