Abstract

Background

Enumerating the complications of groin hernia repair might help to highlight the need for improvement in the quality of care. This is imperative in a country without a strong post-operative complication surveillance mechanism. Hence, this review aims to determine the complications encountered during the surgical treatment of groin hernias among Nigerian subjects.

Methods

Databases like Google Scholar, Scopus, and PubMed were searched. Out of the 140 papers found during the search, only 20 were included in this review. Bassini repair was the most common type of hernia repair used, and neither laparoscopic repair nor posterior approach was utilized in any of the patients. Emergency presentations constituted about 18.5% of the cases. Meta-analysis of the studies showed that more prevalent complications were wound/scrotal edema (derived from four studies), surgical site infections (derived from 17 studies), and hematoma (from 19 studies). The rates were 23% (CI 0–46%; I2 = 80.9%), 6% (CI 3–10%; I2 = 87.7%), and 5% (CI 2–8%; I2 = 83.7%), respectively. The rate of complication in giant hernias was higher than the non-giant hernias and was statistically significant [p < 0.05; OR 1.5 (CI 0.9–2.4)]. Although the recurrence rate is low, there was insufficient follow-up of patients.

Conclusion

This review has shown that one-fifth of the patients had emergency repair of hernias and giant groin hernias have higher odds of complications after repair compared to normal-sized ones. The most common complication noted was wound/scrotal edema. None of the hernias was repaired with laparoscopy. Perhaps, establishing a registry might improve the detection of late complications in patients who had groin hernia repair.
