Management of diastasis recti during ventral hernia repair: an analysis of the abdominal core health quality collaborative.

Abstract

<h4>Purpose</h4>Advancements of minimally invasive techniques leveraged routine repair of concomitant diastasis recti (DR), as those approaches facilitate fascial plication and wide mesh overlap while obviating skin incision and/or undermining. Nevertheless, evidence on the value of such intervention is lacking. We aimed to investigate the management and outcomes of concomitant DR during ventral hernia repair (VHR + DR) from surgeons participating in the Abdominal Core Health Quality Collaborative (ACHQC).<h4>Methods</h4>Patients who have undergone VHR + DR with a minimum 30-day follow-up complete were identified. Outcomes of interest included operative details, surgical site occurrences (SSO), medical complications, and readmissions.<h4>Results</h4>169 patients (51% female, median age 46, median body mass index 31 kg/m²) were identified. Most hernias were primary (64% umbilical, 28% epigastric). Median hernia width was 3 cm (IQR 2-4) and median diastasis width and length were 4 cm (IQR 3-6) and 15 cm (IQR 10-20), respectively. Most operations were robotic (79%), with a synthetic mesh (92%) placed as a sublay (72%; 59% retromuscular, 13% preperitoneal). DR was repaired with absorbable (92%) and running suture (93%). Considering our cohort's relatively small diastasis and hernia size, a high rate of transversus abdominis release was noted (14.7%). 76% were discharged the same day and the 30-day readmission rate was 2% (2 ileus, 1 pneumonia). SSO rate was 4% (6 seromas, 1 skin necrosis) and only one patient required a procedural intervention.<h4>Conclusions</h4>ACHQC participating surgeons usually perform VHR + DR robotically with a retromuscular synthetic mesh and close the DR with running absorbable sutures. Short-term complications occurred in approximately 6% of patients and were mainly managed without interventions. Larger studies with longer-term follow-up are needed to determine the value of VHR + DR.
