Perianal disease, most commonly manifest as fistula or abscess formation, affects up to 40% of patients with Crohn's disease. Perianal Crohn's disease is disabling, associated with poor outcomes, and represents a therapeutic challenge for physicians. Correct diagnosis and classification of perianal disease is the first crucial step for appropriate multidisciplinary management. Areas covered: A literature search was performed of the PubMed database using the terms "transperineal ultrasonography", "transperineal ultrasound", "perianal disease", "perianal fistula", "perianal abscess", "magnetic resonance", "endoanal ultrasonography", "endoscopic ultrasound" in combination with "Crohn's disease"...

BACKGROUND: Anal squamous cell carcinoma (ASCC) is rare, accounting for only 1% of gastrointestinal malignancies. We sought to better understand management strategies for ASCC in the setting of Crohn's disease (CD). METHODS: A retrospective chart review from 2001 to 2016 was conducted using ICD-9/10 codes for CD (555.9/K50) and ASCC (154.3/C44.520). Adult patients with a diagnosis of CD at the time of ASCC diagnosis were included. RESULTS: Seven patients (five female) were included with a median age of 50 years...

Anogenital mammary-like glands (AGMLGs) are nowadays considered a normal component of the anogenital area. Lesions involving AGMLGs are histopathologically very similar to their mammary counterparts, but the information on molecular biological mechanisms in these vulvar/perianal tumors is scarce. Mutations in the PI3K-AKT cascade have been found in hidradenoma papilliferum. The authors studied selected BRCA1, BRCA2, and PIK3CA mutations in series of benign and malignant neoplasms thought to be associated with AGMLGs, including 9 cases of primary extramammary Paget disease, 3 different cases of mammary-type carcinoma (adenoid cystic like, tubulolobular, and invasive ductal like), and 5 cases of hidradenoma papilliferum...

OBJECTIVE: Monogenic defects in the interleukin-10 (IL-10) pathway are extremely rare and cause infantile-onset inflammatory bowel disease (IBD)-like pathology. Understanding how immune responses are dysregulated in monogenic IBD-like diseases can provide valuable insight in "classical" IBD pathogenesis. Here, we studied long-term immune cell development and function in an adolescent IL-10 receptor (IL10RA)-deficient patient who presented in infancy with severe colitis and fistulizing perianal disease and is currently treated with immune suppressants...

Neuroendocrine tumors in gastrointestinal (GI) tract are a rare source of GI malignancy with an estimated incidence of 2.5 - 5 per 100,000 people per year and the prevalence of 35 per 100,000. In the GI tract, they are located in decreasing order of frequency in appendix, ileum, rectum, stomach, and colon. Those found in the anal region represent just 1% of all malignancies of the anal canal. Their clinical presentation can be widely varying, sometimes being found incidentally with metastatic disease and an unknown primary source...

BACKGROUND: Interleukin-10 (IL10) signaling plays an important role in the pathogenesis of very early onset inflammatory bowel disease (VEO-IBD) in children. However, little is known about the role of the IL10 axis in children with VEO-IBD in China. METHODS: The Chinese VEO-IBD Collaboration Group was created to collect clinical and genetic data from patients deficient in IL10 and the IL10 receptor. High-throughput sequencing was performed to identify mutations in these genes...

Pelvic magnetic resonance (MR) imaging is currently the standard for imaging perianal Crohn disease. Perianal fistulas are a leading cause of patient morbidity because closure often requires multimodality treatments over a prolonged period of time. This review summarizes clinically relevant anal sphincter anatomy, imaging methods, classification systems, and treatment objectives. In addition, the MR appearance of healing perianal fistulas and fistula complications is described. Difficult imaging tasks including the assessment of rectovaginal fistulas and ileoanal anastomoses are highlighted, along with illustrative cases...

OBJECTIVES: In pediatric Crohn's disease (PCD), the benefit of microscopy in disease activity assessment and prediction of clinical outcome is, due to the focality and transmurality of the inflammation, disputable. We investigated whether histopathological scoring system predicts complications in pediatric CD and correlates with endoscopical and clinical scores. METHODS: We performed a retrospective study on 63 patients. Endoscopy in the time of diagnosis was evaluated using the Simple Endoscopic Score (SES) and histopathology with the Global Histology Activity Score, both in its original version (GHAS) and its modification (modGHAS)...

BACKGROUND: Colorectal cancer (CRC) has been known to complicate Crohn's disease (CD). Several reports in Western population revealed that CRC in CD were characterized by much younger onset and equal distribution of tumors along the entire colon. However, clinicopathologic features of CD-associated CRC in Korean population have not been well documented yet. METHODS: Among 2968 Korean CD patients, 16 patients (0.54%) were found to develop CRC during follow up. We reviewed clinicopathologic features of the 16 CRC patients...

OBJECTIVE: A relatively large proportion of patients with Crohn disease (CD) develop complications including abscess formation, stricture, and penetrating disease. A subset of patients will have genital and reproductive organ involvement of CD, resulting in significant morbidity. These special circumstances create unique management challenges that must be tailored to the activity, location, and extent of disease. Familiarity with the epidemiology, pathogenesis, imaging features, and treatment strategies for patients with genital CD can aid imaging diagnoses and guide appropriate patient management...

PURPOSE: The outcomes of single-stage transanal endorectal pull-through (SSTEPT) for Hirschsprung disease (HSCR) in young patients are favorable; however, reports have shown that diagnosis and surgery at young ages increase the risk for postoperative enterocolitis and slows postoperative recovery. The present study was primarily designed to evaluate the outcomes of SSTEPT in a multi-institutional cohort of neonates and nonneonates with HSCR. METHODS: Between August 2005 and May 2012, a total of 650 children with HSCR were divided into the following two groups: group A (neonatal group, operative age<28days [n=186]); and group B (nonneonatal group, operative age>28days [n=464])...
