PurposeAbdominal wall hernias are common in the UK and many present in an emergent fashion. The widespread introduction of computed tomography (CT) imaging has transformed surgical practice but out of hours access can be limited by hospital resources and introduce delays. We investigated the influence of preoperative CT imaging in acutely symptomatic hernia and the association with surgical delay and risks of bowel ischemia.MethodsA retrospective analysis of patients undergoing emergency hernia surgery between 2013 and 2021 in a busy UK district general hospital. We evaluated the role of preoperative CT and its influence on timing of surgery, postoperative complications, critical care admission and hospital length of stay.ResultsFive hundred and five patients were studied. Of these, 191 had a preoperative CT scan. Sites of hernia included inguinal in 164 patients (33%); umbilical in 164 (33%); femoral in 69 (14%); incisional in 69 (14%); epigastric in 30 (6%) and Spigelian hernia 9 (2%). Preoperative CT imaging was associated with surgical delay (22.0 h vs 13.0 h, p < 0.001) and an increased need for bowel resection (12% vs 6%, p = 0.027). Delay in surgery was not associated with increased postoperative complications (5% vs 4%, p = 0.474) but was associated with increased critical care admission (11.0% vs 4.8%, p = 0.014).ConclusionsPreoperative CT scan for emergent hernias can delay often inevitable surgery and is associated with an increasing need for more complex, resectional surgery .© 2022.
