From: Retrospective study of an incisional hernia after laparoscopic colectomy for colorectal cancer
Example of CT images of diagnosed IH occurrence. a) Computed tomography (CT) images at 6 months postoperatively. The black line indicates the fascial defect. The length of the horizontal axis was 1.7 cm (minor axis). Six slices of the CT images showed fascial defects; the length of the vertical axis was 3.0 cm (the major axis). The incisional hernia (IH) size was calculated as the ellipse area at 4.0 cm2b) CT images were taken 1 year postoperatively. The black line indicates the fascial defect. The length of the horizontal axis was 3.4 cm (minor axis). Fifteen slices of the CT images showed fascial defects; the length of the vertical axis was 7.5 cm (the major axis). The size of the IH was calculated as the elliptical area at 20.0 cm2
