Abstract
Purpose
Rectus diastasis (RD) associated with abdominal hernias present a surgical challenge associated with a paucity in treatment guidelines. The objective of this systematic review is to review surgical techniques and assess complication and recurrence rates of RD in patients with concurrent abdominal hernias.
Methods
PubMed and EMBASE databases were systematically searched, and data extraction was performed on articles which met the inclusion criteria. Pooled analyses of complication and recurrence rates were performed to compare open vs. minimally invasive surgery. Student t tests were performed to compare differences in continuous outcomes.
Results
Twenty-eight studies were included in this review. RD can be surgically repaired by both open and laparoscopic approaches using both non-absorbable and absorbable sutures. The majority of the techniques reported included mesh insertion either above the aponeurosis, retromuscular, preperitoneal, or intraperitoneal. Open techniques, compared to laparoscopic approaches, were associated with a significantly higher rate of skin dehiscence (6.79% vs. 2.86%; p = 0.003) and hematoma formation (4.73% vs. 1.09%; p < 0.001) and a significantly lower rate of post-operative seroma formation (2.47% vs. 8.29%; p < 0.001). No significant difference in RD recurrence rates were observed between open and laparoscopic repair (0.22 vs. 0.63%, p = 0.17).
Conclusion
Both open and laparoscopic surgery are safe and effective methods that can be used to repair RD in patients with RD and concurrent abdominal hernias as evident by the low recurrence and complication rates and almost negligible major complications post repair.
