Abstract
PURPOSE: To realize a systematic review to evaluate groin hernia surgery for adults in sub-Saharan Africa. METHODS: We conducted a systematic review and meta-analysis, the primary objective of which was to determine the surgical techniques used for unilateral groin hernia surgery in sub-Saharan Africa. Studies published in the last 20 years were considered. A meta-analysis estimated the pooled prevalence with 95% confidence interval (CI) of mortality, chronic pain and recurrence. A subgroup analysis compared the rate of complications between complicated or uncomplicated hernia. RESULTS: We included 113 articles. The most used technique was Bassini in 40.1%, followed by Lichtenstein in 29.9% and Shouldice in 12.6%. The overall mortality rate was 0.6% (95% CI 0.4-0.9). The pooled recurrence rate was 1.4% (95% CI 1.05-1.9). The pooled rate of chronic pain was 2.7% (95% CI 1.9-3.7). We found that mortality rate for complicated hernias (6.4%) was higher compared to uncomplicated hernias (0.2%). This difference was statistically significant [p ≤ 0.001; OR = 47.7; 95 CI (27.2-83.47)]. CONCLUSION: This review showed that pure tissue repairs are the most used techniques with Bassini and Shouldice as leading procedures. The post-operative rates of recurrence and chronic pain are low. However, there is a high heterogeneity between studies than can underestimate these pooled prevalences. The consultation at complication stage remains frequent and associated with a higher mortality. Futures studies should focus on improving the quality of studies in terms of design and follow-up to increase the degree of evidence.
