Endoscopic eTEP Versus Open Rives-Stoppa

Single-Center Observational Study With Comparison of Endoscopic Extended-View Totally Extraperitoneal Prosthesis (eTEP) Versus Open Rives-Stoppa Repair as a Treatment of Midline Abdominal Wall Hernias With Rectus Diastasis

Observational cohort study (partially retrospective, partially prospective) comparing the endoscopic extended totally extraperitoneal prosthesis (eTEP) repair for midline abdominal hernias to open Rives-Stoppa repair (control).

See included study protocol. Included patients will be registered to the European Hernia Society (EHS) registry.

Inclusion Criteria:

Group 1 (eTEP):

• Participants who underwent an eTEP procedure in the investigators' center
• Preoperative existence of one or more midline abdominal wall hernias
• Preoperative existence of rectus abdominis diastasis

Group 2 (Rives-Stoppa, control group):

- Participants who underwent an open Rives-Stoppa (midline repair with sublay mesh) in the investigators' center

Exclusion Criteria:

Group 1 (eTEP):

• Preoperative absence of midline abdominal wall hernias
• Preoperative absence of rectus abdominis diastasis
• Intraoperative performance of transverse abdominis release (TAR)
• Intraoperative inguinal hernia repair

Group 2 (Rives-Stoppa, control group):

• Intraoperative performance of transverse abdominis release (TAR)
• Intraoperative performance of anterior component separation
• Intraoperative inguinal hernia repair
