Abstract

Graphical abstract

Background: several studies were carried out on hernias. The recent studies are concentrated on the architecture of colla-
gen fibers that form the Linea Alba. Objective: To identify the histological structures and the thickness of collagen fibers in Linea Alba of herniated and non- herniated cases. Methods: 14 samples from the herniated patients, 10 samples as control. Histological preparation of slides from both sam- ples was stained by Hematoxylin and Eosin (H&E)and Van Gieson stains. Collagen fibers thickness was estimated by digital microscope with camera. According to length and weight, body mass index (BMI) is measured to identify obese patients. Statistical analysis was done by computer SPSS. Results: Control samples have thick collagen fibers with high density for staining ability and regular arrangement except for some bundles that showed thin collagen fibers in some regions. All the herniated samples were having thin, irregular collagen fibers with some spaces in between the bundles. More de- structive features were seen in herniated samples especially in obese & smoker patients. They had more irregularity in fibers with low staining ability; identified spread of adipose tissue; newly developed blood vessels and some of them were dilated and engorged with blood cells
