Bilateral rectus muscle turning-over for complicated and eventrated abdominal wall hernias: results of a novel method

Abstract

Purpose: We present a technique for covering large midline loss of abdominal wall using a novel method by autologous tissues. Methods: Twenty-two patients (body mass index = 35,6 ± 6,9 kg/m2) were involved in the prospective cohort study. Acute and elective cases were included. The gap area was 450.1 ± 54 cm2. The average width of the midline gap was 16,3 ± 3,2 cm. The rectus muscles were mobilized from its posterior sheath. Both muscles were turned by 180º medially, so that the complete abdominal wall gap could be covered without considerable tension. Changes in intra-abdominal pressure, quality of life and hernia re-currency were determined. Results: There was no significant increase in the intra-abdominal pressure. Wound infection and seroma occurred in four cases. Bleeding occurred in one case. Pre- and post-operative quality of life index significantly improved (23 ± 13 vs. 47 ± 6; p = 0,0013). One recurrent hernia was registered. The procedure could be performed safely and yielded excellent results. The method was applied in acute cases. The intact anatomical structure of rectus muscles was essential. Conclusion: The midline reconstruction with bilateral turned-over rectus muscles provided low tension abdominal wall status, and it did not require synthetic mesh implantation.
