“…In performing the literature review, it was found one systematic review and meta-analysis [ 22 ], one systematic review [ 23 ], two narrative reviews [ 24 , 25 ], one clinical trial [ 26 ], eight observational studies [ [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] ], and one case series [ 35 ], that discussed the relationship between some risk factors, interventions and outcomes in the management of inguinal hernia.…”

“…Johner et al [ 22 ] performed a meta-analysis including four randomized clinical trials, with a total of 1074 herniorrhaphy, where they observed that those patients with the presence of pain and who underwent neurectomies had a higher incidence of postoperative chronic pain (OR 3.70; 95% CI, 2.61–5.25) [ 22 ]. Piga et al [ 23 ] conducted a systematic review of various imaging modalities and their impact on the approach to the patient with inguinal hernia, showing that ultrasound had better performance than computed tomography and magnetic resonance imaging, generally favoring the outcomes in the management of inguinal hernia, especially because it allowed to observe some findings that would facilitate the choice of the most appropriate surgical technique [ 23 ]. However, there is the disadvantage that ultrasound is operator-dependent, although it is now a portable tool that is easy to handle and mobilize.…”

“…They concluded that ultrasound has the highest sensitivity and specificity compared to CT and/or MRI. The sensitivity and specificity of ultrasound for diagnosing inguinal hernias were 56–100% and 0–100%, respectively, whereas the sensitivity and specificity of CT scans ranged from 48 to 98% and 25 to 100%, respectively, and of MRI from 85 to 95% and 90 to 100%, respectively [ 2 ]. In spite of the broader range in sensitivity and specificity observed, on average ultrasonography performed the best.…”

Positive predictive value of ultrasound in correctly identifying an inguinal hernia: a single-centered retrospective pilot study

Objectives To determine the clinical utility of preoperative ultrasound imaging for predicting an inguinal hernia in need of surgery. In addition, we aimed to identify factors associated with false positive (FP) ultrasound examinations. Methods In this retrospective pilot study, we included all 175 patients who underwent inguinal hernia surgery in our hospital in 2019 and of whom a positive preoperative ultrasound examination of the groin area was available. The positive predictive value (PPV) of the ultrasound examination was determined using inguinal hernia detected during surgery (yes/no) as golden standard. To identify possible predictive factors, we compared the characteristics of patients with a FP ultrasound with patients with a true positive (TP) ultrasound. Results PPV of ultrasound examinations to identify an inguinal hernia in need of surgery correctly was 90.9% (159/175). The patients with a FP ultrasound examination had a significantly higher body mass index (BMI) than the patients with a TP ultrasound examination (27.6 ± 4.2 vs 25.8 ± 2.3, p = 0.043). Conclusions With a false positive percentage of 9.1%, there is still room for improvement of preoperative diagnostic imaging. Studies with larger cohorts are necessary to establish prediction models that have the potential to reduce FP ultrasound results.

Rationale and objectives The objective of this study was to analyze the role of dynamic magnetic resonance imaging (MRI) in patients who suffered from groin pain and whose physical examination and ultrasound returned inconclusive/indefinite results, as well as in patients receiving an ongoing assessment for a previous herniotomy. Material and methods For this study, 25 patients 14 women and 11 men were selected with a mean age of 41.6 years, including clinical complaints, such as groin pain and or a previous herniotomies. These patients underwent dynamic MRI. Reports were created by a radiology resident and a radiology consultant. Clinical and ultrasound documentation were compared to with imaging results from the MRI. Results The results of the dynamic MRI were negative for 23 patients (92%) and positive for two patients (8%). One patient suffered from an indirect hernia and one from a femoral hernia. A repeated hernia was an excluding for the preoperated patients with pain and ongoing assessment. Conclusions Dynamic MRI shows substantially higher diagnostic performance in exclusion of inguinal hernia, when compared to a physical examination and ultrasound. The examination can also be used in assessments to analyze the operation’s results.
