Pain After Insufflation for Robotic Sacrocolpopexy (PAIRS) Trial

August 5, 2026 updated by: Henry Ford Health System
This study evaluates post-operative pain between different insufflation pressures during robotic-assisted sacrocolpopexy. Subjective pain and narcotic usage after surgery will be measured.

Detailed Description

This is a prospective single-blind randomized controlled trial of adult women undergoing robotic-assisted sacrocolpopexy for pelvic organ prolapse. Each surgery will be performed by a board-certified Female Pelvic Medicine & Reconstructive Surgery (FPMRS) surgeon with a standard technique other than pneumoperitoneum level. A sacrocolpopexy for apical prolapse may be performed at the same time as a hysterectomy and other clinically indicated procedures if desired by the patient and as part of the standard of care. Patients will be stratified by hysterectomy prior to randomization. Postoperatively, patients will be evaluated with a Visual Analogue Scale (VAS) as well as prescribed narcotic analgesic use and followed up to 2 weeks.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Standard Insufflation Group
Patients will receive standard insufflation during surgery (15 mm Hg).
This is the amount of insufflation using during the surgical procedure.
Experimental: Low Insufflation Group
Patients will receive a lower level of insufflation during surgery (12 mm Hg or lower).
This is the amount of insufflation using during the surgical procedure.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post-operative Pain on a visual analogue scale, ranging from 1-10 with a higher score meaning more pain.
Time Frame: Pain will be assessed within 24 hours of the surgery. .
Pain will be assessed during the 24-hour post-operative period.
Pain will be assessed within 24 hours of the surgery. .
Post-operative Pain on a visual analogue scale, ranging from 1-10 with a higher score meaning more pain.
Time Frame: Pain will be assessed at the two-week post-operative follow-up visit.
Pain will be assessed during the two-week post-operative period.
Pain will be assessed at the two-week post-operative follow-up visit.
Safety using Operation length, blood loss, need to increase insufflation, operative conversion rates. These are all counts with higher numbers meaning worse outcomes.
Time Frame: Safety will be assessed during the procedure.
The safety of the lower insufflation pressure will be assessed during the procedure.
Safety will be assessed during the procedure.
Safety using Operation length, blood loss, need to increase insufflation, operative conversion rates. These are all counts with higher numbers meaning worse outcomes.
Time Frame: Safety will be assessed immediately post-operatively.
The safety of the lower insufflation pressure will be assessed immediately post-operatively.
