Introduction: Endoscopic treatment of diastasis rectus abdominis offers the possibility of correcting the condition without complete abdominoplasty. The purpose of this study was to develop a training method on fresh cadavers models based on a literature review on this surgery.

Material and methods: The endoscopic procedure considered involved the insertion of a 10mm suprapubic trocar and of 5mm trocars in each iliac fossae. The muscle suture is done using running barbed suture. The surgery was performed on eight fresh cadavers to estimate the learning curve for this intervention, which was estimated with the CUSUM method. A systematic literature review in the PubMed database was performed, and 20 articles that met the inclusion criteria were analyzed.

Results: The learning curve threshold was reached after 6 operations and can be separated into two phases. The most common complication of this surgery is seroma, it is encountered in 3 to 27% of cases according to the studies. Diastasis recurrence is rare, occurring in less than 2% of cases. In comparison, open surgical treatment of diastasis recti is associated with a higher risk of hematoma, skin necrosis and longer operating times. Recurrence rates are similarly low after open and endoscopic repair. Mesh reinforcement is indicated in cases of diastasis wider than 5cm, diastasis recurrence, severe musculoaponeurotic laxity, or hernia larger than 1cm.

Conclusion: The data in the literature indicate that laparoscopic surgery is an efficient and safe approach to correct diastasis of the rectus muscles and can be offered by plastic surgeons to selected patients.
