Background: Incisional hernia is a common problem following open abdominal surgery. Hernia repair in patients with relevant medical conditions is a topic of controversy due to the high risk of morbidity and recurrence. We investigated the risk of recurrence in patients with relevant medical conditions managed with a prosthesis in the retromuscular position.
Methods: A retrospective review of the data of patients undergoing midline incisional hernia repair was performed. The outcomes of patients with relevant concomitant medical conditions defined as ASA scores >2 were compared with those of healthier patients with ASA scores ≤2.
Results: 115 patients including 41 with ASA >2 and 74 with ASA ≤2 were included for analysis. There were no statistically significant differences amongst both groups with regard to the size of the hernia defect, the duration of surgery (123.0 ± 71 vs. 149.0 ± 92 min, p = 0.73), the incidence of postoperative seroma (14.6% vs. 29.7%, p = 0.07), postoperative hematoma (12.2% vs. 4.1%, p = 0.10) and surgical site infection (14.6% vs. 8.1%, p = 0.27). No statistically significant difference was seen amongst both groups with respect to the rate of long-term recurrence after a median follow-up of 63.0 ± 36 months (12.2% vs. 6.8%, p = 0.32).
Conclusion: Relevant medical condition alone cannot be seen as a contraindication for midline incisional hernia repair using the retromuscular technique. Rates of morbidity and long-term recurrence following mesh-associated closure are not difference from those of healthier patients.
