Background
Lateral abdominal wall hernias (LAWH) constitute about 1–4% of hernia surgical procedures. They represent a unique surgical challenge on account of their potential for anatomical complexity and consequent operative technical demand. Furthermore, LAWH repairs are currently not standardized, and remain contentious, despite a variety of approaches. These repairs are attendant with not insignificant morbidity and recurrence rates. We profile here our endoscopic and hybrid surgical approach to the management of LAWH and early therapeutic outcomes.
Methods
A retrospective review of our hernia clinical database between March 2018 and December 2020 was performed to extract all LAWH (with and without an associated midline component) patients, who underwent an enhanced-view totally extra peritoneal (eTEP) hernia repair with a transversus abdominis release (TAR), or a hybrid repair. Initial outcome data (6-month follow-up) is profiled here. The primary outcome measures were hernia recurrence and hernia-site bulging. The secondary measures were surgical site occurrence (SSO) and hernia-related quality of life (QoL).
Results
A total of 33 LAWH patients underwent an eTEP TAR or hybrid hernia repair. 11 patients had an associated midline defect and 12 were recurrent hernias. The mean hernia defect area was 84.2 ± 49 cm2 and mean mesh size was 859.6 ± 263 cm2. There was no hernia recurrence at initial follow-up of 24 months. The SSO rate was 12%. The CCS QoL scores were 34.6 ± 2 pre-operatively, and improved to 27.2 ± 4 at 6 months.
Conclusions
Our endoscopic and hybrid technique is a safe, reproducible, and technically promising approach for the repair of LAWH. Thorough knowledge of the surgical anatomy of the lateral abdominal wall and advanced endosurgical skills are imperative for good outcomes. We await the long-term results of our LAWH cohort to confirm the findings.
