P-014 surgical treatment of complex incisional hernias

Aim to study the early and long-term outcomes of the abdominal wall reconstruction (AWR) of complex incisional hernias. Material & Methods We retrospectively reviewed prospectively collected data from 121 patients with 1 to 7 years of follow-up, who underwent midline AWR between 2015 and 2022. The complexity of hernia was determined according to the criteria of N. J. Slater et all. All patients had a hernia gate width ≥10cm (W3). “Loss of domain”≥20% had 38% of patients, a recurrence after previously performed mesh-reinforced AWR (R1–5) - 36%, purulent fistulas, trophic ulcers and chronic seromas - 9%. Three laparotomies or more in anamnesis had 48.7% patients. Obesity had 74.4%; type II diabetes mellitus - 26.5%; COPD - 15.7%. Mesh-reinforced fascial repairs were used in 73 (60.33%) cases, bridged repairs were used in 48 (39.67%) cases. Results Wound complications in the early postoperative period were observed in 48 (40.5%) patients. Long-term outcomes: recurrence hernia - 7 (5.8%), ligature fistula - 3 (2.5%), chronic wound - 2 (1.6%), pseudocyst - 3 (2.5%), building of the mesh - 7 (5.8%). Mesh-reinforced AWRs with primary fascial coaptation resulted in fewer hernia recurrences (2.7% vs 10.4%) and fewer wound (31.5% vs 52.2%) and overall (5.5% vs 16.6%) complications than bridged repairs. At the same time, bridged repairs resulted in fewer postoperative pain (9.6% versus 4.2%) than mesh-reinforced AWRs. Conclusions Surgical treatment of patients with complex incisional hernias requires the use of combined techniques for AWR using a mesh, which reduces the recurrence to 5.8%.
