Analysis of Superficial Subcutaneous Fat Camper’s and Scarpa’s Fascia in a United States Cohort

Together, the Camper’s and Scarpa’s fasciae form the superficial fat layer of the abdominal wall. Though they have clinical and surgical relevance, little is known about their role in body composition across diverse patient populations. This study aimed to determine the relationship between patient...

description Together, the Camper’s and Scarpa’s fasciae form the superficial fat layer of the abdominal wall. Though they have clinical and surgical relevance, little is known about their role in body composition across diverse patient populations. This study aimed to determine the relationship between patient characteristics, including sex and body mass index, and the distribution of Camper’s and Scarpa’s fascial layers in the abdominal wall. A total of 458 patients’ abdominal CT examinations were segmented via CoreSlicer 1.0 to determine the surface area of each patient’s Camper’s, Scarpa’s, and visceral fascia layers. The reproducibility of segmentation was corroborated by an inter-rater analysis of segmented data for 20 randomly chosen patients divided between three study investigators. Pearson correlation and Student’s t-test analyses were performed to characterize the relationship between fascia distribution and demographic factors. The ratios of Camper’s fascia, both as a proportion of superficial fat (r = −0.44 and p < 0.0001) and as a proportion of total body fat (r = −0.34 and p < 0.0001), showed statistically significant negative correlations with BMI. In contrast, the ratios of Scarpa’s fascia, both as a proportion of superficial fat (r = 0.44 and p < 0.0001) and as a proportion of total body fat (r = 0.41 and p < 0.0001), exhibited statistically significant positive correlations with BMI. Between sexes, the females had a higher ratio of Scarpa’s facia to total body fat compared to the males (36.9% vs. 31% and p < 0.0001). The ICC values for the visceral fat, Scarpa fascia, and Camper fascia were 0.995, 0.991, and 0.995, respectively, which were all within the ‘almost perfect’ range (ICC = 0.81–1.00). These findings contribute novel insights by revealing that as BMI increases the proportion of Camper’s fascia decreases, while the ratio of Scarpa’s fascia increases. Such insights expand the scope of body composition studies, which typically focus solely on superficial and visceral fat ratios.
