Abstract

Background: Recurrent abdominal hernias remain a significant clinical challenge, with relatively high recurrence rates despite prosthetic mesh repair. Accurate imaging modalities are essential to assess mesh positioning and detect complications. Our study aims to compare computed tomography (CT) and magnetic resonance imaging (MRI) for mesh visualization, recurrence detection, and related postoperative outcomes in recurrent hernia patients.

Methods: A systematic review and meta-analysis were conducted, including CT scan or MRI studies, to assess mesh visualization in recurrent hernia cases. A comprehensive search of PubMed, Scopus, Embase, and Web of Science was performed up to July 2024. Data were extracted for mesh visualization, recurrence rates, seroma detection, and reoperation rates. Statistical analysis employed a random-effects model with subgroup analysis for CT and MRI modalities.

Results: A total of 26 studies were included (18 for CT, and 8 for MRI). Recurrence rates were 20% (95% CI: 0-42%) for CT-based studies and 15% (95% CI: 4-26%) for MRI-based studies (p = 0.72). MRI exhibited superior mesh visualization (73%; 95% CI: 42-100%) compared to CT-(48%; 95% CI: 0-100%) (p = 0.44) studies. Seroma detection rates were similar: 12% (95% CI: 4-19%) for CT- and 10% (95% CI: 4-15%) for MRI- (p = 0.65) studies. Reoperation rates were 6% (95% CI: 1-11%) for CT- and 34% (95% CI: 3-66%) for MRI-based studies, showing a non-significant trend (p = 0.08).

Conclusion: CT and MRI offer distinct advantages in detecting mesh-related complications after hernia surgery. CT remains preferred for identifying recurrence and acute complications, while MRI excels in mesh visualization and soft-tissue assessment. Tailored imaging strategies based on clinical scenarios can optimize outcomes and improve postoperative care.

期刊介绍： Hernia was founded in 1997 by Jean P. Chevrel with the purpose of promoting clinical studies and basic research as they apply to groin hernias and the abdominal wall . Since that time, a true revolution in the field of hernia studies has transformed the field from a ”simple” disease to one that is very specialized. While the majority of surgeries for primary inguinal and abdominal wall hernia are performed in hospitals worldwide, complex situations such as multi recurrences, complications, abdominal wall reconstructions and others are being studied and treated in specialist centers. As a result, major institutions and societies are creating specific parameters and criteria to better address the complexities of hernia surgery. Hernia is a journal written by surgeons who have made abdominal wall surgery their specific field of interest, but we will consider publishing content from any surgeon who wishes to improve the science of this field. The Journal aims to ensure that hernia surgery is safer and easier for surgeons as well as patients, and provides a forum to all surgeons in the exchange of new ideas, results, and important research that is the basis of professional activity.
