Abstract
Background
Functional outcomes after robotic and laparoscopic Intersphincteric resections (ISR)
have not been studied adequately. We aimed to compare the bowel functions after robotic
or laparoscopic ISR.
Methods
Single-center, cross-sectional study of minimally invasive ISR. Functional outcomes
were assessed on the low anterior resection syndrome (LARS), Wexner incontinence scale,
and the Kirwan grading. Baseline characteristics (age, sex, body mass index, T stage,
tumour height, preoperative radiation, and anastomotic configuration) in the groups
were balanced using inverse probability of treatment weighting (IPTW).
Results
Functional outcomes were assessed for 132 patients, 85 laparoscopic and 47 robotic
ISR were performed. After IPTW, baseline characteristics were well balanced (mean
deviation <0.1). In the weighted cohorts of laparoscopic and robotic ISR, major LARS
was observed in 18.1% and 18.5% (p – 0.182) and major incontinence on the Wexner scale
in 18.4% and 22.8% (p – 0.443), respectively. The Kirwan grades of incontinence were
also similar between the groups (p – 0.794).
Conclusion
No differences in bowel functions on the LARS and incontinence scales between laparoscopic
and robotic ISR were found in the present study.
