Abstract
BACKGROUND: Abdominal wall reconstruction for complex ventral and incisional hernias is associated with significant complications. Commonly, the peritoneal cavity is opened and adhesiolysis is performed with the potential for enterotomy. A totally extraperitoneal (TE) approach to abdominal wall reconstruction is feasible in many ventral hernia repairs and can reduce visceral injuries without impacting other outcomes. This study compares outcomes after retro-rectus ventral hernia repairs with TE and transabdominal (TA) preperitoneal approaches. STUDY DESIGN: An IRB-approved review of a prospective hernia database was performed for all ventral hernia repairs between 2009 and 2013. Preoperative patient characteristics, including demographics and comorbidities; operative variables, including surgical technique, operative duration, type/size/location of mesh, concomitant procedures, and incidence of inadvertent injury; and patient outcomes in terms of length of stay, wound and nonwound complications, and readmissions or returns to the operating room were obtained. Groups were compared using t-tests, Mann-Whitney U tests, chi-square tests, and Fisher's exact tests as appropriate. Significance was set at p < .05. RESULTS: One hundred and seventy-five complex abdominal wall reconstructions were performed between 2009 and 2013. Of those, 85 patients underwent hernia repair for CDC grade 1 hernias with retro-rectus mesh placement performed (n = 45 TA, n = 40 TE). Groups did not differ in age, BMI, sex, smoking status, hernia defect size, history of COPD, asthma, hypertension, cancer, or renal failure. More TA patients had diabetes (36% vs. 13%; p = 0.02) and previous hernia repair (73% vs. 45%; p = 0.01) than TE patients. Mesh size was larger in the TE group (625 ± 234 cm(2) vs. 424 ± 214 cm(2); p < .001). There was no difference in enterotomy between TA and TE groups (0% vs. 2%; p = 1.0). However, there was a reduced operative time with TE (170 ± 49 minutes vs. 212 ± 49 minutes; p < .001). CONCLUSIONS: Abdominal wall reconstruction can be performed safely in a TE fashion. The extraperitoneal approach results in shorter operative duration, but had similar complications when compared with TA preperitoneal approach.
