Prevalence and risk factors of inguinal hernia: a study in a semi-urban area in Rayalaseema, Andhra Pradesh, India

The inheritance of groin hernias: an updated systematic review with meta-analyses

PURPOSE

The aim of this systematic review was to assess the inheritance of groin hernias.

METHODS

The primary outcome was to assess the inheritance based on the family history of groin hernias. We included studies that reported family history in patients with groin hernias, assessed the development of groin hernias in patients with a positive family history, or assessed the development of groin hernias in twins. Searches were conducted in PubMed, EMBASE, and Cochrane CENTRAL in November 2021. Results were synthesized narratively and with meta-analyses.

RESULTS

Twenty-two studies with unique participants were included. While two twin studies did not show convincing results of a genetic origin in children, database studies with low risk of bias showed that a positive history in parents or siblings increased the risk of inguinal hernia in children, and the risk was highest between mothers and daughters and between sisters. In adults, patients with inguinal hernia had higher odds of having a positive family history compared with patients without groin hernia (odds ratio 5.3, 95% confidence interval 3.3-8.7), and a nationwide study found the highest risk of inguinal hernia repair when a sister had been repaired compared with a brother. This study also found that having a sibling repaired for a groin hernia increased the risk of femoral hernia repair.

CONCLUSION

Despite studies being heterogeneous, there is overwhelming evidence that a positive family history is a risk factor for developing inguinal hernia in both children and adults, seemingly with a pronounced female-female inheritance pattern.

Hernia among Patients Admitted to the Department of Surgery of a Tertiary Care Centre

Introduction

Hernia is one of the most common surgical conditions causing disability and requiring hospital admission and surgery. The aim of this study was to find out the prevalence of hernia among patients admitted to the Department of Surgery of a tertiary care centre.

Methods

A descriptive cross-sectional study was conducted among patients admitted to the Department of Surgery between 14 April 2021 and 13 April 2023 and were collected from 1 July 2023 to 31 July 2023 from the hospital records. Ethical approval was obtained from the Institutional Review Committee. The patient admitted to the Department of Surgery was included and those with incomplete data were excluded. Convenience sampling was used. The point estimate was calculated at a 95% Confidence Interval.

Results

Out of 2057 patients, the prevalence of hernia was 247 (12.01%) (10.61-13.41, 95% Confidence Interval). A total of 31 (12.55%) hernias were irreducible and 15 (6.07%) were operated in the emergency setting. The most common type of hernia was inguinal hernia found in 169 (68.42%) and hypertension was the most common comorbidities found in 48 (19.43%).

Conclusions

The prevalence of hernia was similar to other studies done in similar settings. Hernia accounts for a major surgical burden in our setting. So, early diagnosis and treatment could reduce the morbidity and mortality related to it.

Study of Demographics, Clinical Profile and Risk Factors of Inguinal Hernia: A Public Health Problem in Elderly Males

BACKGROUND

Inguinal hernia repair is the most commonly performed elective surgery in India draining significant healthcare resources. This observational study was conducted at a tertiary-level institute in northern India to look into the demographics, clinical profile and risk factors of inguinal hernia.

METHOD

 This study was conducted as an observational study at the tertiary care centre of northern India, including 110 patients who had come to the surgical outpatient department for inguinal hernia repair. After obtaining informed consent from all the participants, demographic details, history and clinical examination were recorded. This was a prospective, single-centre, non-randomized, observational study.

RESULTS AND DISCUSSION

 In our study, 43 patients (39%) were >50 years of age. One hundred and seven patients (97.27%) were males, and three (2.72%) were females. Male: Female ratio was 32:1. The preponderance of males was due to their involvement in more strenuous exercises and lifting weights and the anatomical differences between them. The main risk factor in the present study was lifting heavy weights 55%, followed by altered bowel habits 36.36% and respiratory disease (chronic obstructive airway disease). Smoking and diabetes were also associated as risk factors for the hernia. In this study, the most common side of hernia was on the right side, 63%, on the left, 33% and bilateral in 4% of patients. The indirect hernia was the most common type.

CONCLUSION

Inguinal hernia is a surgical problem found commonly in the male elderly. Right-sided inguinal hernia is common, with the indirect type being more frequent. Heavy weight lifting and strenuous exercises were commonly found risk factors.

Worldwide magnitude of inguinal hernia: Systematic review and meta-analysis of population-based studies

This review pooled the magnitude of inguinal hernia based on the available population-based studies conducted throughout the world. We have searched for population-based articles reporting the magnitude of inguinal hernia on PubMed/Medline, EMBASE, Cochrane library and Google Scholar. Random-effect meta-analysis was carried out to pool the magnitude of inguinal hernia and its proportion between male and female subjects. To determine the presence of between-study heterogeneity, I2 and Cochran's Q methods were employed. Publication bias was evaluated by the Egger test and visual examination of a funnel plot. All statistical tests were conducted by Stata version 16 software. Ten population-based studies with a total population of 51,304,093 were incorporated to pool the magnitude of inguinal hernia. The pooled prevalence of inguinal hernia was 7.7% (95% confidence interval: 6.06-9.34). Subgroup analysis showed that the highest pooled prevalence of inguinal hernia (12.72%) was observed in Asia, On the contrary, the lowest pooled prevalence emanated from America, 4.73%. The pooled prevalence of inguinal hernia in males is far higher than females. It was, respectively, 9.61% (95% confidence interval: 6.46-12.76) and 1.31% (95% confidence interval: 0.36-2.26) for males and females. The current meta-analysis revealed a higher burden of inguinal hernia. This finding glares the light that giving greater attention to inguinal hernia is required. It is recommended to identify the significant causes of inguinal hernia and design appropriate prevention as well as management strategies.

Prevalence and associated factors of external hernia among adult patients visiting the surgical outpatient department at the University of Gondar Comprehensive Specialised Hospital, Northwest Ethiopia: a cross-sectional study

OBJECTIVES

This study was aimed to assess the prevalence and associated factors of external hernia among adult patients visiting the surgical outpatient department (OPD) at the University of Gondar Comprehensive Specialised Hospital (UOGCSH), Northwest Ethiopia.

STUDY DESIGN

Institution-based cross-sectional study was conducted from 5 April 2020 to 22 June 2020.

STUDY SETTING

UOGCSH.

PARTICIPANTS

All adult patients above 18 years of age who visited the surgical OPD at the UOGCSH.

OUTCOME

Prevalence of external hernia.

RESULT

A total of 403 study participants were involved in this study with a response rate of 100%. The prevalence of external hernia was 11.7% (95% CI 8.8% to 15.1%). The epigastric hernia had the highest prevalence 16 (34%), followed by inguinal hernia 14 (29.8%). Old age (adjusted OR (AOR) =2.47, 95% CI 1.06 to 5.78), constipation (AOR 3.67, 95% CI 1.68 to 8.11), chronic cough (AOR 5.18, 95% CI 2.17 to 12.3) and lifting of heavy objects (AOR 7.39, 95% CI 3.36 to 16.2) had a statistically significant association with external hernia.

CONCLUSION

Regardless of hardly any significant gender difference, the overall prevalence of external hernia was high. Old age, constipation, chronic cough and lifting of heavy objects were found to have a significant association with an external hernia. Patients who have constipation and cough should get appropriate treatment early.
