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

PURPOSE

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).

METHODS

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.

RESULTS

169 patients (51% female, median age 46, median body mass index 31 kg/m) 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.

CONCLUSIONS

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.
