e-TEP repair for midline primary and incisional hernia: technical considerations and initial experience.

Introduction: The Enhanced-View Totally Extra Peritoneal Rives-Stoppa (e-TEP-RS) Technique for the repair of large, complex, ventral abdominal hernias has gained popularity especially in overcoming the disadvantages with Intra Peritoneal Onlay Mesh (IPOM) repairs and to enable siting of a large prosthetic mesh in an anatomical plane distinct from the abdominal cavity and its contents. Evolving variations of the original technique have allowed the definitive repair of such defects in a reproducible manner. We present our initial experience of this approach and detailed steps of our native technical modifications in overcoming the challenges in performing this complex and potentially challenging procedure.

Materials And Methods: This is a retrospective review of the clinical data of midline, large, complex, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR). Patients, with or without Diastasis of Rectus Abdominis Muscle (DRAM) were included. Key outcomes measured were post-operative pain, operative morbidity, readmission, Quality of Life (QoL), hernia recurrence.

Results: A total of 58 midline, ventral abdominal hernia patients who underwent e-TEP-RS with and without Transversus Abdominis Release (TAR), between March 2018 and December 2019 were studied. Mean defect area was 41.0 ± 28 cm and the mean mesh surface area was 473.5 ± 165 cm. e-TEP-RS was done in 35 cases, e-TEP RS TAR in 15 cases and e-TEP-RS with e-TEP inguinal in 08 cases. There was no intraoperative morbidity. Mean duration of surgery was 156.2 ± 40 min and mean blood loss was 40.5 ± 26 cc. The CCS QoL scores improved from 34.6 (± 2) pre-operatively to 27.2 (± 4) at the end of 6 months. One patient had a supra-umbilical recurrence following bilateral TAR over the superior edge of the mesh. Follow-up ranged from 6 to 22 months, with a mean of 14 months. Major complications (n = 12; 20.7%) were seroma formation and prolonged ileus.

Conclusion: The e-TEP-RS technique for large, complex, midline, ventral abdominal hernias can be used with excellent results and acceptable morbidity. This technique is technically challenging and should be mastered in relatively smaller ventral hernias to achieve good results before attempting it in larger, complex ones.
