Umbilical and bilateral inguinal hernias in a veteran powerlifter: is it a pressure-overload syndrome?

Work-relatedness of inguinal hernia: a systematic review including meta-analysis and GRADE

Purpose

Clinicians need to know whether inguinal hernia (IH) can be attributed to work to answer questions regarding prevention and medical causation. This review describes whether work-related risk factors are associated with IH.

Methods

A systematic review was performed in Medline via PubMed until February 3rd, 2020. Inclusion criteria were that IH was diagnosed by a clinician, and workers exposed to work-related risk factors were compared to workers less exposed or not at all. A quality assessment and a meta-analysis using Cochrane’s RevMan 5.3 were performed, including GRADE for quality of evidence.

Results

The search resulted in 540 references. Fourteen studies fulfilled the inclusion criteria, of which three were included in a meta-analysis, all three being of high quality, including 621 workers diagnosed with IH. The meta-analysis revealed significant associations with physically demanding work (OR 2.30, 95% CI 1.56–3.40). Two prospective studies, including 382 and 22,926 cases revealed associations that this was true for male workers with a lateral IH that reported standing or walking for more than six hours per workday (OR 1.45, 95% CI 1.12–1.88) or lifting cumulative loads of more than 4000 kg per workday (OR 1.32, 95% CI 1.27–1.38). The level of certainty for the latter two work-related risk factors was moderate and high according to GRADE.

Conclusion

Lateral IH among males is associated with work-related risk factors depending on the level of exposure to the time standing/walking per workday, or the amount of load lifted per workday.

Work related aspects of inguinal hernia: a literature review

INTRODUCTION

There is a traditional belief that that an inguinal hernia can be the result of increased intra-abdominal pressure (IAP) and therefore the development of a hernia may be attributed to single strenuous or recurrent strenuous events. As a result of this, litigation in this area is frequent.

METHODS

Medline was searched for English language publications using the keywords of 'hernia' or 'hernia AND recurrence' combined with 'work related', 'physical activity' and 'intra abdominal pressure'. The reference lists of appropriate papers identified on the original search were also checked to identify all related publications.

RESULTS

The search revealed 268 papers of which 59 were identified as appropriate to the subject of this review. Although publications in this area are scarce, from the literature available to date, there is no evidence to support the idea that single or recurrent strenuous events or early return to work related activity should result in the formation or recurrence of an inguinal hernia.

CONCLUSION

Although immediate pain at the time of an intensive or recurrent activity followed by a new diagnosis of a hernia supports a link between the activity and the hernia occurrence, it is likely that a congenital or acquired weakness in the connective tissue or muscles of the patient meant that hernia occurrence was almost inevitable. This may have significant implications regarding 'work related' hernia and its associated litigation.

Training Room Management of Medical Conditions: Sports Gastroenterology

Gastrointestinal (GI) illnesses are common in athletes. Various causes include adverse physiologic adaptations of the gut during exercise; excess ingestion of carbohydrate drinks, alcohol, and anti-inflammatory medications; emotional stressors; exposure to pathogens in closed environments and during travel; trauma; and abdominal wall pressure overload. Unfortunately, evidence-based management of GI illnesses in athletes is limited because most studies have compared various GI illnesses between different sports, rather than comparing athletes to nonathletes. This article reviews the evidence that is available specifically relating to etiology, pathophysiology, clinical presentation, relevant differential diagnoses, acute management, and recommendations for specialist consultation of various GI illnesses in the training-room setting.
