Transabdominal bowel ultrasonic diagnosis of complications of small bowel Crohn disease / 中国医学影像技术

ABSTRACT

Objective:To observe the value of transabdominal bowel ultrasound (TBUS) in diagnosis of complications of small bowel Crohn disease (SBCD). Methods: Imaging manifestations on 42 times ultrasonic examinations of 25 SBCD patients during 10 years were retrospectively analyzed, including 26 times in active phase (active group) and 16 times in remission stage (remission group). The consistency between ultrasound and Harvey Bradshaw index (HBI) for evaluation on disease activity was observed. Results: There was high consistency between ultrasound and HBI for evaluation on disease activity of SBCD (Kappa=0.897). Fistula, abscess and inflammatory mass all appeared in active stage. The incidence of stenosis, creeping fat sign, lymphadenitis and ascites in active group were significantly higher than those in remission group (all P<0.05). The thickness of intestinal wall and creeping fat in active group were significantly greater than those in remission group (all P<0.05). Among all 42 times examinations, stenosis was observed in 15 times, fistula was found in 8 times, while inflammatory hyperplasia of adipose tissue around the diseased intestinal wall, multiple mesenteric lymphadenitis and ascites were noticed in 31,20 and 16 times, respectively. Abdominal masses were detected in 9 times, including 5 with abscess. Perforated Intestinal wall was found in 1 time, while inflammatory hypertrophy and diverticulum formation were detected in 8 and 3 times, respectively. Conclusion: TBUS could accurately show the abdominal complications of SBCD,therefore being able to be used as a routine imaging method for evaluation on complications of SBCD.
