Management of midline ventral hernias in a surgical department of sub-Saharan Africa: A retrospective cohort study.

Introduction: The linea alba is the second most frequent site of abdominal wall hernias after the inguinal region. Prosthetic approach, often recommended, comes up against the low socio-economic level and the availability of these materials in developing countries. Our objective is to evaluate the indications and results of midline ventral hernia surgery. Methods: This was a retrospective cross-sectional study over 36 months including all adult patients (over 15 years old) treated for primary or recurrent midline ventral hernias. The parameters studied were: age, sex, risk factors, type of hernia according to the classification of the European Hernia Society (EHS), clinical presentation, hernial ring size, surgical technique and results (recurrence, chronic pain). Results: We included 65 patients. The mean age was 40.5 years ± 16.4. There was a female predominance (56.3%, n = 36) with a sex ratio of 0.77. According to the EHS classification, type M3 (umbilical) was more common (67.2%), followed by type M2 (epigastric) in 25% and M4 (infra-umbilical) in 1.6%. According to the clinical presentation, 85.6% (n = 55) were uncomplicated, 10.9% (n = 7) were strangulated in and 3.1% (n = 2) incarcerated. A primary suture was performed in 93.8% (n = 61) and a mesh repair in 6.15% (n = 4). With a mean follow-up of 8.2 ± 11.9 months, we noted a recurrence in 6.1% (n = 4) and chronic pain in 6.1% (n = 4). Conclusion: There is a need to individualize or contextualize the guidelines. In our context where meshes are not always available, pure tissue repairs keep their place in the treatment.
