Hospital readmission following open, single-stage, elective abdominal wall reconstructions using acellular dermal matrix affects long-term hernia recurrence rate

Background: We evaluated the incidence of and the risk factors for readmission in patients who underwent abdominal wall reconstruction (AWR) using acellular dermal matrix (ADM) and assess whether readmission affects AWR long-term outcomes. Methods: A retrospective, single-center study of patients underwent AWR with ADM was conducted. The primary outcome was the incidence of unplanned readmission within 30 days after the initial discharge post-AWR. Secondary outcomes were surgical site occurrence (SSO) and hernia recurrence at follow-up. Results: Of 452 patients (mean age, 59 years; mean follow-up, 35 months), 29 (6.4%) were readmitted within 30 days. Most readmissions were due to SSO (44.8%) or wound infections (12.8%). The hernia recurrence rate was significantly higher in readmitted patients (17.2% vs 9.9%; P = 0.044). Wider defects, prolonged operative time, and coronary artery disease were independent predictors of readmission. Conclusions: Readmission is associated with hernia recurrence on long-term follow-up. SSO is the most common cause for readmission.
