The Impact of Groin Surgery during Childhood on the Incidence of Inguinal Hernia Repair and Its Postoperative Complications in Adult Life

Adolescent inguinal hernia repair: a review of the literature and recommendations for selective management

BACKGROUND

The choice of how to repair inguinal hernias in adolescents has historically been a matter of experience and differed between pediatric surgeons who traditionally performed a high ligation of the sac and general surgeons who typically perform a repair using mesh. This up-to-date review thoroughly examines the subject and discusses the suitability of both types of repairs in this unique age group.

METHODS

A 20-year Pub Med search was performed for the following terms: adolescent hernia repair including reports of mesh hernia repair in adolescents and postoperative complications including chronic inguinal pain and recurrences.

RESULTS

The evidence in the literature suggests that while there appears to be no difference between the two types of repairs with regards to recurrence and complications, changes in the pelvic floor physiology in adolescents suggest that a selective, individualized approach can be recommended depending on the size and nature of the presenting pathology.

CONCLUSIONS

A selective approach to the inguinal hernia in adolescent patients based on the size of the defect appears justified.

The efficacy and safety of preoperative glucocorticoids in herniorrhaphy: a systematic review and meta-analysis

Postoperative pain is the main reason for delayed recovery after herniorrhaphy. Preoperative glucocorticoid administration may improve postoperative recovery. The present study assessed the efficacy of preoperative glucocorticoids in facilitating recovery after herniorrhaphy. Randomized controlled trials (RCTs) conducted up to January 2021 were searched in electronic databases and trial registries. Meta-analyses were performed using random effects models. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to assess the certainty of evidence. Seven RCTs (744 patients) were included in the meta-analysis. Preoperative glucocorticoid administration reduced patients' pain on postoperative day 0 (standard mean difference [SMD] = - 0.73, 95% confidence interval [CI] - 1.45 to - 0.01; I² = 94%). However, there was no marked difference in rescue analgesic use (risk ratio [RR] = - 0.06, 95% CI - 0.28 to - 0.16; I² = 0%) or vomiting (RR = 0.78, 95% CI 0.50-1.20; I² = 30%) between preoperative glucocorticoid administration and control. The certainty of evidence was moderate because of inconsistencies or imprecision. No serious adverse effects were observed. Preoperative glucocorticoid administration reduced pain in patients following herniorrhaphy without increasing the occurrence of adverse events. Further studies will be required to confirm the efficacy of preoperative glucocorticoids.

Androgen Deprivation Therapy and the Risk for Inguinal Hernia: An Observational Nested Case Control Study

It has been suggested that hypogonadism increases the risk for inguinal hernia (IH). The aim of this study was to investigate any association between androgen deprivation therapy (ADT) for prostate cancer and increased risk for IH. The study population in this population-based nested case-control study was based on data from the Prostate Cancer Database Sweden. The cohort included all men with prostate cancer who had not received curative treatment. Men who had been diagnosed or had undergone IH repair (n = 1,324) were cases and controls, where not diagnosed, nor operated on for IH, matched only on birth year (n = 13,240). Conditional multivariate logistic regression models were used to assess any temporal association between ADT and IH, adjusting for marital status, education level, prostate cancer risk category, Charlson Comorbidity Index, ADT, time since prostate cancer diagnosis, and primary prostate cancer treatment. Odds ratio (OR) for diagnosis/repair of IH 0 to 1 year from start of ADT was 0.5 (95% confidence interval [CI] = [0.38, 0.68]); between 1 and 3 years after, the OR was 0.35 (95% CI = [0.26, 0.47]); between 3 and 5 years after, the OR was 0.39 (95% CI = [0.26, 0.56]); between 5 and 7 years after, the OR was 0.6 (95% CI = [0.41, 0.97]); and >9 years after, the OR was 3.68 (95% CI = [2.45, 5.53]). The marked increase in OR for IH after 9 years of ADT supports the hypothesis that low testosterone levels increase the risk for IH. The low risk for IH during the first 8 years on ADT is likely caused by selection of men with advanced cancer unlikely to be diagnosed or treated for IH.

Inguinal hernia repair in inpatient children: a nationwide analysis of German administrative data

Background

Contrary to adult inguinal hernia surgery, large-scale investigations using registries or administrative data are missing in paediatric surgery. We aimed to fill this gap by analysing German administrative hospital data to describe the current reality of inpatient hernia surgery in children.

Methods

We analysed aggregated data files bought from the German federals statistics office on hospital reimbursement data separately for principal diagnoses of inguinal hernia in children and for herniotomies in inpatients. Developments over time were assessed via regression and differences between groups with nonparametric comparisons.

Results

Principal diagnoses of hernias were decreasing over time with the exception of male bilateral and female bilateral incarcerated hernias in the first year of life which increased. The vast majority of operations were conducted via the open approach and laparoscopy was increasingly only used for females older than 1 year of age. Recurrent hernia repair was scarce. Rates of inguinal hernia repair were higher in both sexes the younger the patient was, but were also decreasing in all age groups despite a population growth since 2012. The amount of inguinal hernia repairs by paediatric surgeons compared to adult surgeons increased by 1.5% per year.

Conclusions

Our results corroborate previous findings of age and sex distribution. It demonstrates that inpatient hernia repair is primarily open surgery with herniorrhaphy and that recurrences seem to be rare. We observed decreasing rates of hernia repairs over time and as this has been described before in England, future studies should try to elucidate this development.
