Abstract

Preoperative imaging with computed tomography (CT) scans can be useful in preoperative planning. We hypothesized that CT measurements of ventral hernia defect size and abdominal wall thickness (AWT) would correlate with postoperative complications and need for complex abdominal wall reconstruction (AWR). Patients who underwent open ventral hernia repair and had preoperative abdominal CT imagining were identified from an institutional hernia-specific surgery outcomes database at our tertiary referral hernia center. Grade III and IV hernias and biologic mesh cases were excluded. CT measures of defect size and AWT were analyzed and correlated to complications and the need for AWR techniques using univariate, multivariate, and principal component (PC) analyses. PC1 and PC2 used five AWT measures, hernia defect width, and body mass index to create a new component variable. There were 151 open ventral hernia repairs included in the study. Preoperative findings included 37.7% male; age 55.3 ± 12.5 years; body mass index (BMI) 33.3 ± 7.8 kg/m(2); 60.3% were recurrent hernias with average defect width 8.5 ± 5.0 cm and area 178.3 ± 214 cm(2); AWT at umbilicus 3.5 ± 1.8 cm; and AWT at pubis 7.0 ± 3.2. Component separation was performed in 24.0% of patients and panniculectomy in 34.4%. Wound complications occurred in 13.3% patients, and 2.7% had hernia recurrence. Increasing defect width, length, and area as well as select AWT measurements were associated with increased need for component separation, concomitant panniculectomy, and higher rates of wound and total complications (all P < 0.05). Using multivariate regression, PC1 was associated with wound complications (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.01-1.16); PC2 (hernia defect width) was associated with the need for component separation (OR, 1.16; 95% CI, 1.03-1.30). Hernia recurrence was not predicted by AWT or defect size (OR, 1.00; 95%CI, 0.87-1.15). Preoperative CT measurements of hernia defects and AWT predict wound complications and the need for complex AWR techniques. Obtaining preoperative CT imaging should be a consideration in preoperative planning and may help with patient counseling.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 June 2015.
All research outputs
#19,944,994
of 25,374,647 outputs
Outputs from Journal of Surgical Research
#4,133
of 5,778 outputs
Outputs of similar age
#189,864
of 278,177 outputs
Outputs of similar age from Journal of Surgical Research
#78
of 140 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,778 research outputs from this source. They receive a mean Attention Score of 4.3. This one is in the 22nd percentile – i.e., 22% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 278,177 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 140 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
