Introduction: With obesity on the rise, more patients with a higher body mass index (BMI) are likely to require incisional hernia repairs. The aim of this study is to evaluate the impact of BMI on outcomes of laparoscopic ventral hernia repair.

Methods: We retrospectively reviewed the laparoscopic ventral hernia repairs performed from 2002 to 2009 at a single institution. We divided the patients into two groups; BMI≤30 kg/m2 and BMI>30 kg/m2. We looked at demographics, operative time, whether the hernia was an initial or a recurrent hernia, morbidity, and mortality.
 

Results: We had a total of 308 cases who qualified for this study.
 

  BMI≤30 Kg/m2 BMI>30 kg/m2 p-value 
N 123 185    ——-
Initial Hernia 101 134 p=0.05 
Recurrent Hernia 22 51 p=0.05
Male /Female 56/67 75/110 p=0.38
Age 57 (22-85) 51 (22-84) p<0.001
BMI 25.8 (17-30) 36.4 (31-73) p=0.84
Operative Time 110 min 118 min p=0.20
Hospital Stay 1.13 days 0.97 days p=0.41
Morbidities 14 (11.4%) 27 (14.6%) p=0.21
Mortalities 1 (0.8%) 0 (0%) p=0.44
Recurrence 6 (4.9%) 13 (7%) p=0.44
Seroma 2 (1.6%) 11 (5.9%) p=0.65
Wound Infection 2 (1.6%) 2 (1.1%) p=0.67
Mesh Infection 4 (3.3%) 4 (2.2%) p=0.55
Bowel Injury 3 (2.4%) 0 (0%) p=0.03

Small Bowel Obstruction  

1 (0.8%) 1 (0.5%) p=0.77
Re-Intubate 0 (0%) 1 (0.5%) p=0.41
Urinary Problems 2 (1.6%) 1 (0.5%) p=0.34

Conclusions: Laparoscopic ventral hernia repair can be successfully performed in the obese population with increases in complication and recurrence rate, that were not significantly different based on this sample size.
