Prosthetic mesh hernioplasty versus primary repair in incarcerated and strangulated groin and abdominal wall hernias with or without organ resection. Retrospective study.

Purpose: The use of synthetic materials in emergency surgery for abdominal wall hernia in a potentially infected operating field has long been debated. In the present study, we evaluated the outcome of mesh prostheses in the management of incarcerated and strangulated abdominal wall hernias with or without organ resection. Methods: Between March 2012 and January 2020, medical records of 301 patients who underwent emergency surgery for incarcerated and strangulated abdominal wall hernias were retrospectively evaluated. The interventions were exclusively realized by two surgical teams, one of which used polypropylene mesh prostheses (group I), whereas the second team performed primary hernia repair (group II). The outcome of patients was observed for a mean follow-up period of 18.2 months. Categorical data were analyzed with the χ2 test or likelihood ratio. Logistic regression was used for adjustments in multivariate analysis. Statistical analyses were realized with SPSS, version 18. P values < 0.05 were considered statistically significant. For multiple comparisons between types of hernia, the significance level was set to P < 0.0083 according to Bonferroni adjustment. Results: Of the 301 patients, 190 were men (63.1%), and 111 were women (36.9%). The mean age was 59,98 years (range 17–92). Overall, 226 (75.1%) patients were treated with synthetic mesh replacement. One hundred two organ resections (34%) were performed involving the omentum, small intestine, colon, and appendix. No significant difference was identified in terms of postoperative complications, between the two groups both in patients who underwent organ resection and in patients who did not. Conclusion: Synthetic materials may safely be used in the emergency management of incarcerated and strangulated groin and abdominal wall hernias in patients with or without organ resection, although they cannot formally be recommended due to the limited number of cases of the present study.
