INTRODUCTION: Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare entity that mimics various inflammatory strictures of the small intestine. Pediatric literature is scarce. We analyzed the clinical, radiological, endoscopic and histopathological features of children with CMUSE that differentiate it from small bowel Crohn's disease (SBCD) and gastrointestinal tuberculosis (GITB).
METHODS: CMUSE was diagnosed by the following criteria: (1) unexplained small bowel strictures with superficial ulcers, (2) chronic/relapsing ulcers of small bowel after resection, (3) no signs of systemic inflammation, (4) absence of other known etiologies of small bowel ulcers. SBCD and GITB were diagnosed based on standard criteria. The clinical features, laboratory parameters, radioimaging, endoscopy (including video capsule endoscopy [VCE], intra-operative endoscopy), histopathological features and treatment outcome were noted.
RESULTS: Out of 48, CMUSE was diagnosed in 13 (27%) isolated small bowel and ileocecal strictures, while GITB and SBCD accounted for 41% and 21% cases, respectively. Common presentations were sub-acute obstruction (46%), obscure gastrointestinal bleeding (38%) and protein-losing enteropathy (38%). CMUSE patients had significantly longer disease duration compared to SBCD and GITB (p < 0.001). SBCD (90.0%) and GITB (85%) cases had elevated C-reactive protein (CRP), none with CMUSE had elevated CRP (p < 0.001). The disease was localized in jejunum (100%) and proximal ileum (56%) in CMUSE, ileocecal region (85%) in GITB, but evenly distributed in small intestine in SBCD. Endoscopy showed evenly placed, superficial, circumferential ulcers with strictures in CMUSE, deep linear ulcers in SBCD and circumferential ulcers in GITB. Upfront immunosuppression was given in four; three (75%) of them relapsed. Only surgery was done in three with one (25%) having relapse. Upfront surgery followed by immunosuppression was used in six, but all relapsed and two required repeat surgery.
CONCLUSION: CMUSE is important but underdiagnosed in children. Lack of constitutional symptoms, normal inflammatory parameters and characteristic ulcers with strictures helped in differentiating CMUSE from GITB and SBCD.
