OBJECTIVES: This study aims to characterize pediatric inflammatory bowel disease (IBD) patients who change diagnosis and describe the characteristics of that change. METHODS: A retrospective study was conducted on pediatric IBD patients from the ImproveCareNow (ICN) multicenter international cohort from 2007 to January 2019. Primary outcome was change in diagnosis after the first four visits. Other variables included demographics, diagnostics, disease characteristics, and timing. RESULTS: 6.1% of 18,055 patients aged 1-20 years changed diagnosis. Median time between the baseline visit and first diagnosis change was 0.9 years. Change in diagnosis occurred in 257/12,178 (2.1%) patients with Crohn's disease (CD), 347/4758 (7.3%) patients with ulcerative colitis (UC), and 495/1119 (44.2%) patients with IBD-Unclassified (IBD-U). In multivariable analysis, initial diagnosis of IBD-U and longer follow-up times were associated with greater odds of a diagnosis change. CONCLUSION: IBD-U initial diagnosis and longer follow-up were associated with increased diagnosis change risk. The most common change was reclassification to CD. Disease activity, moderate malnutrition, and presence of EIMs were not associated with change in diagnosis.

Familial adenomatous polyposis (FAP) is a rare syndrome caused by adenomatous polyposis coli (APC) gene mutation resulting in the development of hundreds of adenomatous colorectal polyps. The disease process usually manifests fully by the second decade of life. Total colectomy or restorative proctocolectomy is often required to prevent the development of colorectal adenocarcinoma. Routine surveillance following surgery is critical for the early detection of polyps or malignancy. We present a rare case of a 31-year-old male with a history of FAP status post total proctocolectomy with ileal pouch-anal anastomosis (IPAA) who presented with acute exacerbation of lower back pain and new-onset lower extremity paresthesia. Imaging demonstrated an aggressive T12 vertebral body lesion. Pathology following laminectomy demonstrated metastatic adenocarcinoma. Subsequent pouchoscopy revealed a distal 1.5-cm pedunculated lesion arising from remnant rectal tissue with pathology confirming moderately differentiated rectal adenocarcinoma. This patient underwent a prophylactic proctocolectomy 20 years prior to this admission but was lost to follow-up prior to any endoscopic evaluations. Despite postoperative surveillance guidelines and patient counseling, follow-up and recommended endoscopic evaluation are often inadequate. This case examines potential socioeconomic factors influencing the completion of surveillance endoscopy and also represents an opportunity to incorporate education and provide resources to patients with FAP to improve surveillance examinations and mitigate the development of preventable malignancies.
Deployment of bare metal duodenal stents for individuals with gastric outlet obstructions (GOOs) is a well-characterized measure to improve the quality of life. However, these interventions are palliative in nature and are associated with known complications. We present an unfortunate case of a previously not well described, albeit not surprising, a complication of stent placement. The individual underwent duodenal stent placement due to obstructive metastatic disease and subsequently presented for gastrointestinal (GI) bleed. It was determined that an aortoduodenal fistula acutely developed and, despite heroic efforts, the patient ultimately expired.
