“…High sensitivity and high penetration power are the key advantages of WIUS [23]. WIUS has successfully been used to describe the US features of gastric carcinoma [24] and the intestine [14,15]. WIUS can directly scan tissues shortly after gastrointestinal tract resection, providing a clear image that avoids the possibility of errors caused by inexperienced examiners.…”

“…A reliable or definite diagnosis of CD could be obtained, and the diseased intestinal segment was resected in surgery. According to the criteria of the Japanese Research Committee on Inflammatory Bowel Disease [15], a diagnosis of CD was made by gastroenterologists on the basis of history, physical exam, laboratory/radiological studies, and gastrointestinal histology. From December 2006 to December 2017, enterectomy was performed in 396 patients with a definite diagnosis of CD in our hospital.…”

“…Kunihiro et al used WIUS to successfully identify wall stratification in 91.3% of CD lesions [14]. Very recently, Yaguchi et al also found that WIUS clearly visualized the thickness and hierarchical structure of a bowel segment involving CD [15]. Although WIUS is highly sensitive for diagnosis, the inconvenience of its in vitro study limits its clinical application compared with TAUS.…”

The aim of this study is to clarify whether trans-abdominal ultrasound (TAUS) can reflect actual intestinal conditions in Crohn’s disease (CD) as effectively as water-immersion ultrasound (WIUS) does. This retrospective study enrolled 29 CD patients with 113 intestinal lesions. Five ultrasound (US) parameters (distinct presence/indistinct presence/disappearance of wall stratification in the submucosal and mucosal layers; thickened submucosal layer; irregular mucosal surface; increased fat wrapping around the bowel wall; and fistula signs) that may indicate different states in CD were determined by TAUS and WIUS for the same lesion. Using WIUS as a reference standard, the sensitivity, specificity, and accuracy of TAUS were calculated. The degree of agreement between TAUS and WIUS was evaluated by the kappa coefficient. All US parameters of TAUS had an accuracy >70% (72.6–92.7%). The highest efficacy of TAUS was obtained for fistula signs (sensitivity, specificity, and accuracy values were 63.6%, 96.0%, and 92.7%, respectively). All US parameters between TAUS and WIUS had a definitive (p ≤ 0.001) and moderate-to-substantial consistency (kappa value = 0.446–0.615). The images of TAUS showed substantial similarity to those of WIUS, suggesting that TAUS may function as a substitute to evaluate the actual intestinal conditions of CD.
