Background: The aim of this study is to analyze the data collected on lateral incisional hernias (LIH) in the National Incisional Hernia Registry (EVEREG) and assess current practices and outcomes in LIH repair.
Methods: A retrospective cohort study was conducted using LIH data recorded over 10 years (2012-2022). Comorbidities, hernia characteristics, short-term complications, and recurrences were studied, along with their association with the type of approach used, either open or laparoscopic, in elective surgery.
Results: 1742 LIH cases were studied. According to the EHS classification, these included L1 409 (23.5%), L2 388 (22.3%), L3 565 (32.4%), L4 150 (8.6%) and combined 230 (13.2%). An open approach was performed in 1528 (87.7%) cases and laparoscopic in 214 (12.3%). The median age was 66 ± 12.45 years, with a majority of males, 934 (53.6%). The median body mass index was 29 ± 5.18 kg/m2. The most observed comorbidity was arterial hypertension (957 patients, 55%). A specialist was present in 638 interventions (56%). The 24-month follow-up was 17.9%, and recurrence in those cases was 27.2%, with a higher incidence when there was no specialist present during the intervention, onlay mesh position, and larger defect size.
Conclusions: Surgery for LIH is common, although laparoscopic approach remains infrequent. Furthermore, it is associated with a high percentage of recurrences that increases when there is no specialist in abdominal wall surgery present.
