Surgical repair carries high morbidity and mortality. Hence, prevention of PSH formation would be ideal, which requires better understanding of risk factors. We aimed to examine the role of abdominal rectus muscle (ARM) thickness and its postoperative atrophy in PSH pathogenesis. We hypothesised that a thin ARM upon stoma creation is a risk factor for PSH development, and that patients developing PSH show a higher degree of postoperative ARM atrophy compared to patients without PSH.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Radiological bilateral ARM measurements on 205 patients, before and after rectal cancer surgery with Hartmann\u2019s procedure or abdominoperineal resection, among Swedish patients recruited retrospectively from the Swedish Colorectal Cancer Registry.
