Abstract
PURPOSE Small bowel obstruction (SBO) is a common surgical emergency. Previous studies have shown the value computed tomography (CT) scanning in both confirming this diagnosis and identifying indications for urgent surgical intervention, such as strangulated bowel or closed loop obstructions. However, most of the literature is based on retrospective expert review of previous imaging and little data regarding the real-time accuracy of CT reporting is available. Here, we investigated the real-world accuracy of CT reporting in patients admitted with SBO. METHODS This was a multicentre prospective study including consecutive patients admitted with SBO. The primary outcomes were the sensitivity and specificity of CT scanning for bowel obstruction with ischaemia and closed loop obstruction. Data were retrieved from the original CT reports written by on-call radiologists and compared with operative findings. RESULTS One hundred seventy-six patients were included, all of whom underwent CT scanning with intravenous contrast followed by operative management of SBO. Bowel obstruction with ischaemia was noted in 20 patients, with a sensitivity and specificity of CT scanning of 40.0% and 85.5%, respectively. Closed loop obstructions were noted in 26 patients, with a sensitivity and specificity of CT scanning of 23.1% and 98.0%, respectively. CONCLUSIONS The real-world accuracy of CT scanning appears to be lower than previously reported in the literature. Strategies to address this could include the development of standardised reporting schemas and to increase the surgeon's own familiarity with relevant CT features in patients admitted with SBO.

Abstract
AIMS The optimal management of small bowel obstruction (SBO) remains a matter of debate and treatment varies internationally. In Denmark, a more surgically aggressive strategy has traditionally been used, but to what extent patient outcomes differ from international reports is unknown. This study aimed to describe the current management and outcomes of patients admitted with SBO in Denmark. METHODS This was a prospective cohort study conducted at six acute hospitals in Denmark over a 4-month period. Patients aged ≥ 18 years with a clinical or radiological diagnosis of SBO were eligible. Primary outcomes were 30 day morbidity and mortality rates. RESULTS 316 patients were included during the study period. The median age was 72 years and 56% were female. Diagnosis was made by computed tomography (CT) in 313 patients (99.1%), with the remaining three diagnosed clinically. Non-operative management was the initial strategy in 152 patients (48.1%) and successful in 119 (78.3%). Urgent surgery was performed in the remaining 164 (51.9%), with a laparoscopic approach used in 84 patients (51.2%). The entire cohort had a 30 day mortality rate of 7.3% and a 30 day morbidity rate of 17.1%. CONCLUSIONS The management of SBO in Denmark differs markedly to previous international reports, with an almost ubiquitous use of CT for diagnosis and a high proportion of patients undergoing urgent surgery. Despite higher rates of surgery, patient outcomes are broadly similar to reports of more conservative strategies, perhaps due to a reduction in delayed operations.
