Laparoscopic retromuscular hernia repair (LaHRR): a case-series of 17 patients treated with a novel technique for laparoscopic ventral hernia and diastasis repair.

Abstract

Many minimally invasive techniques have been developed over the years to treat primary ventral hernias and rectus abdominis diastasis, all of which have their advantages and disadvantages in terms of complications, reproducibility, and cost. We present a case-series of a novel approach that was safe and reproducible in a cohort of 17 patients. All patients in the study underwent the novel procedure between October 2022 and July 2023. We collected data retrospectively, including patient general characteristics, surgical outcomes, and complications. Patient follow-up lasted 12months to exclude recurrences. Seventeen patients underwent the procedure for primary uncomplicated ventral hernias and rectus diastasis. The median length of hospital stay was 2days (IQR 2-3). In 4 out of 17 cases minor complications occurred within 30days, of which 3 were class I and 1 was a class II complication according to the Clavien-Dindo classification. There were no recurrences. Although limited by a small cohort of patients and a non-comparative study design, our study presents encouraging results in regards to the safety of this technique. More studies with a larger study population are needed to evaluate the benefits and pitfalls of this new technique.[query names].
