Operative Correction of Rectus Muscle Diastasis (ARD): the Effect on Low Back Pain and Movement Control

Not Applicable
Conditions
Diastasis Recti
Interventions
Procedure: Suture repair
Procedure: Rolled mesh repair
Registration Number
NCT03509376
Lead Sponsor
Helsinki University Central Hospital
Brief Summary

This study is a randomized controlled trial comparing two ADR repair methods: nylon suturing and nylon suture with mesh enforcement. The ADR correction is performed simultaneously with abdominoplasty/ modified skin reduction abdominoplasty.

Detailed Description

Abdominal diastasis recti (ADR) persists after pregnancies in one third of women. Traditionally plain ADR has been managed conservatively. There is some evidence that ADR reduces abdominal integrity and functional strength, contributing to pelvic instability and back pain. However, patients are referred to a surgeon mainly because of some other primary concern and ADR is an additional condition: in the case of excess skin-subcutis, the person is referred to a plastic and reconstructive surgeon for abdominoplasty and in the case of midline hernia, to a general surgeon.

In combination with abdominoplasty the plication of the superficial aponeurosis of recti muscles is the most commonly used reconstructive technique. There is a wide variety of different plication procedures available. Convincing data of the long-term results of ADR repair are lacking especially when ADR is severe. Some studies have reported large recurrence rates. Polypropylene mesh repair is an evidence-based technique to ensure a strong and reliable abdominal wall repair in ventral hernias or in high risk laparotomy wounds. Large retromuscular or intraperitoneal meshes have been used also in ARD repair.

This study reports a novel surgical technique aimed at reliable and mini-invasive open repair of ADR with or without midline hernia combined by abdominoplasty for symptomatic ADR patients. In RmB (roll mesh in between) method the investigators bury a narrow piece of self-gripping mesh inside the plicated linea alba to give tensile strength to plication. Patients are randomized to a suture plication group or RmB group.

Outcome evaluation is performed by clinical examination with video recorded movement control tests and with structured questionnaires for Quality of Life (RAND36) and for low back pain (LBP) (Oswestry 2.0). Evaluation is done three times: when recruiting the patient, after a conservative 3-6 months therapy with written instructions and one year after the intervention. Complications and recurrences are recorded as well.

Outcomes The effect of ADR repair on LBP and movement control problems Patient satisfaction and complications of ADR repair after the two techniques
