Impact of Minimal Incision Repair of Rectus Abdominis Diastasis on Quality of Life and Stress Incontinence: A Prospective Study

TL;DR

A new surgical method for repairing abdominal muscle separation in postpartum women significantly improves physical strength, daily activities, and urinary issues.

Contribution

The MIRRAD procedure is introduced as an effective surgical treatment for postpartum rectus abdominis diastasis, with measurable improvements in physical and urinary health.

Findings

MIRRAD significantly improved physical activity levels, including vigorous activity and steps per minute.

The procedure enhanced back and abdominal muscle strength and trunk stability.

Urinary symptoms like frequency and leakage were significantly reduced post-surgery.

Abstract

This study evaluates the impact of the minimal incision repair of rectus abdominis diastasis (MIRRAD) procedure on physical activity, muscle strength, quality of life, and overall satisfaction in women with postpartum rectus abdominis diastasis (PP-RAD).

A cohort of 31 female patients, aged 20–50 years, diagnosed with PP-RAD unresponsive to conservative treatment, underwent the MIRRAD procedure. Assessments were conducted preoperatively and 1 year postoperatively, these included the Modified Abdominal Trunk Function Protocol (MATFP), Disability Rating Index (DRI), and Urinary Disability Index (UDI) questionnaires. Physical activity intensity was monitored using accelerometers.

Significant improvements were observed in vigorous physical activities (Z = −2.352, p = 0.019), vector magnitude counts per minute (Z = −2.163, p = 0.031), and steps per minute (Z = −3.131, p = 0.002). DRI showed significant improvements in physical tasks like dressing, walking, and strenuous work (Z ranging from −2.705 to −4.603, p < 0.001). UDI indicated significant improvements in urinary symptoms, including reduced frequency (Z = −2.984, p = 0.003) and less urinary leakage (Z = −2.357, p = 0.018). MATFP demonstrated gains in back and abdominal muscle strength (Z = −4.321, p < 0.001) and trunk stability (Z = −3.991, p < 0.001).

The MIRRAD procedure significantly improves physical strength, trunk stability, and urinary function, enhancing daily activities and overall physical health in women with PP-RAD. Further research is recommended to evaluate long-term outcomes.
