Abstract
Introduction: Topic of this review is to provide a systematic overview of the current evidence on the management of patients after manual reduction of an incarcerated inguinal hernia.
Methods: Available literature regarding incarcerated or strangulated inguinal hernias published until March 2019 was obtained and reviewed. 32,021 papers were identified, of which only 20 were of a sufficient value to be used in this review.
Results: The terms ‘incarcerated’ and ’strangulated’ are used interchangeably in the literature making separate analysis of these two entities almost impossible, although manual reduction is very unlikely to be successful when the hernia has strangulated contents. Following successful manual reduction, mesh repair is generally superior compared to pure tissue repair with regard to recurrence rates. Nevertheless, mesh repair is associated with a significant increase in the surgical site infection (SSI) rate, especially when bowel necrosis is present. The laparoscopic approach provides the benefits of avoiding an unnecessary laparotomy and reducing associated morbidity, but it does require the availability of appropriate equipment and an appropriately skilled surgical team.
Conclusion: A mesh repair is generally superior to a pure tissue repair in the surgical management of emergency inguinal hernias, reducing the recurrence rate, but can be associated with an increased risk of SSI depending on the level of contamination. The laparoscopic approach is recommended if an experienced surgical team and necessary equipment are available.
