Abstract：
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.

摘要：
背景：本研究的目的是分析国家切口疝登记处（EVEREG）收集的外侧切口疝（LIH）的数据，并评估LIH修复的当前实践和结果。
方法：使用10年（2012-2022年）记录的LIH数据进行回顾性队列研究。合并症,疝的特点，短期并发症,并对复发情况进行了研究，以及它们与所用方法类型的联系，开放或腹腔镜，在选择性手术中。
结果：研究了1742例LIH病例。根据EHS分类，其中包括L1409(23.5%)，L2388（22.3%），L3565（32.4%），L4150（8.6%）和合并230（13.2%）。开腹手术1528例(87.7%),腹腔镜手术214例(12.3%)。中位年龄为66±12.45岁，大多数男性，934（53.6%）。中位体重指数为29±5.18kg/m2。最常见的合并症是动脉高血压（957例患者，55%）。638项干预措施中有一名专家(56%)。24个月的随访率为17.9%，复发率为27.2%,当干预期间没有专家在场时，发病率较高，onlay网格位置，和更大的缺陷尺寸。
结论：LIH手术很常见，尽管腹腔镜方法仍然很少见。此外，它与高百分比的复发相关,当没有腹壁手术专家时,复发会增加。
