摘要："PurposeThe objective of incisional hernia surgery is to achieve the restoration of abdominal wall anatomical and physiological functions. This study aims to investigate the impact of abdominal wall reconstruction on abdominal muscle alterations by measuring the preoperative and postoperative changes in abdominal wall muscles in patients undergoing incisional hernia repair.MethodsFor patients undergoing open incisional hernia abdominal wall reconstruction, preoperative and postoperative abdominal CT scans were analyzed at a minimum of 3 months post-surgery. 3D Slicer software was utilized for measuring preoperative and postoperative changes in abdominal cavity volume, abdominal muscle volume, as well as muscle volume, cross-sectional area, and abdominal circumference at specific levels. The acquired data were subjected to statistical analysis using SPSS software.ResultsA total of 40 patients meeting the inclusion criteria underwent open incisional hernia repair surgery. Some of these patients required component separation technique (CST) due to the larger size of the hernia sac. The abdominal muscles surrounding the hernia ring were defined as the ""damaged group,"" while the remaining abdominal muscles were defined as the ""undamaged group."" Measurements revealed a significant increase in the volume of rectus abdominis, external oblique, internal oblique, and transversus abdominis muscles in the damaged group. Similarly, there was a corresponding increase in the volume of rectus abdominis, external oblique, internal oblique, and transversus abdominis muscles in the undamaged group.ConclusionsAfter abdominal wall reconstruction in incisional hernia patients, not only is their anatomical structure restored, but the overall biomechanical integrity of the abdominal wall is also repaired. The damaged muscles are subjected to renewed loading, leading to the reversal of disuse atrophy and an increase in muscle volume."
