November 28, 2021 updated by: Li Chuan, Southwest Hospital, China

Short Term Outcomes of Robotic-assisted Intersphincteric Resection for Low Rectal Cancer:A Multicentric Randomized Controlled Trial

This study compared robot-assisted total mesorectal excision to treat very low rectal cancer within 2 cm from the dentate line to avoid permanent colostomy. improves the quality of life with better defecation function, urinary function and sexual function.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in urinary function
Time Frame: 6 months
The days of indwelling catheter after operation The overall efficiency of urination function
6 months
Change in International Index of Erectile Function [IIEF] score
Time Frame: 18 months
Alterations in IIEF scores from baseline up to 18 months postoperatively - 15 item questionnaire, each item range from 0 - 5, with total score to 30. lower score indicates more severe erectile dysfunction (ED)
18 months
Change in FIQL scores
Time Frame: 18 months
Alterations in Fecal Incontinence Quality of Life Instrument (FIQL) scores from baseline up to 18 months postoperatively - 29 items range from 1 (strongly agree) to 4 (strongly disagree); with a 1 indicating a lower functional status of quality of life. Scale scores are only calculated if at least half of the items have been answered
18 months
Change in Female Sexual Function Index [FSFI]
Time Frame: 18 months
Alterations in FSFI from baseline up to 18 months postoperatively - 19-item self-report measure, each item ranges from 0-5, with full range from 2 to 36, with low score indicating sexual function disorder.
18 months
