METHODS: We performed a prospective, population-based study of IBD incidence in predefined catchment areas, collecting data for 1 year, starting on April 1, 2011. New cases were ascertained from multiple overlapping sources and entered into a Web-based database. Cases were confirmed using standard criteria. Local endoscopy, pathology, and pharmacy records were searched to ensure completeness of case capture.
RESULTS: We identified 419 new cases of IBD (232 of ulcerative colitis [UC], 166 of Crohn's disease [CD], and 21 IBD-undetermined). The crude annual overall incidence values per 100,000 individuals were 1.37 for IBD in Asia (95% confidence interval: 1.25-1.51; 0.76 for UC, 0.54 for CD, and 0.07 for IBD-undetermined) and 23.67 in Australia (95% confidence interval: 18.46-29.85; 7.33 for UC, 14.00 for CD, and 2.33 for IBD-undetermined). China had the highest incidence of IBD in Asia (3.44 per 100,000 individuals). The ratios of UC to CD were 2.0 in Asia and 0.5 in Australia. Median time from symptom onset to diagnosis was 5.5 months (interquartile range, 1.4-15 months). Complicated CD (stricturing, penetrating, or perianal disease) was more common in Asia than Australia (52% vs 24%; P = .001), and a family history of IBD was less common in Asia (3% vs 17%; P < .001).
CONCLUSIONS: We performed a large-scale population-based study and found that although the incidence of IBD varies throughout Asia, it is still lower than in the West. IBD can be as severe or more severe in Asia than in the West. The emergence of IBD in Asia will result in the need for specific health care resources, and offers a unique opportunity to study etiologic factors in developing nations.
METHODS: A systematic review and meta-analysis were performed of published studies from 1950 to 2010 using keyword searches in MEDLINE, EMBASE, EBM Reviews, and BIOSIS Previews.
RESULTS: In all, 477 abstracts were identified and data extracted from 93 studies, comprising 17,976 IBD patients and 27,350 age- and sex-matched controls. Major nucleotide oligomerization domain (NOD)-2 variants in Western Crohn's disease (CD) patients were not associated with CD in Han Chinese, Japanese, South Korean, Indian, and Malaysian populations. New NOD2 mutations were, however, associated with CD in Malaysians (JW1), Han Chinese, and Indians (P268S). Autophagy-related protein 16-linked 1 (ATG16L1) was not associated with CD in East Asians (odds ratio [OR] 0.97; 95% confidence interval [CI] 0.84-1.13). Interleukin (IL)-23R was associated with CD in South Koreans (OR 1.8; 95% CI 1.16-2.82) and a single nucleotide polymorphism in IL-23R (Gly149Arg) was protective of CD in Han Chinese (OR 0.3; 95% CI 0.15-0.60). Tumor necrosis factor (TNF) superfamily gene-15 (SF15) polymorphisms were associated with CD (OR 2.68; 95% CI 1.86-3.86), while TNF-308 polymorphisms (OR 1.82; 95% CI 1.15-2.9), cytotoxic T lymphocyte antigen (CTLA)-4 (OR 2.75; 95% CI 1.22-6.22) and MICA allele (OR 2.41; 95% CI 1.89-3.07) were associated with ulcerative colitis in Asians.
CONCLUSIONS: Genetic mutations of IBD in Asians differ from Caucasians. New mutations and susceptibility genes identified in Asian IBD patients provide an opportunity to explore new disease-associated mechanisms in this population of rising incidence.
METHODS: A cross-sectional study using IMPACT-III questionnaires evaluating HRQoL in children aged 8-17 years with duration of IBD of ≥6 months was conducted. IMPACT-III, a validated instrument designed to measure HRQoL in children with IBD, was used. Higher IMPACT-III (maximum = 100) score indicates better HRQoL. Impact of socio-demographic and clinical factors of IBD on the HRQoL was evaluated. Paediatric Crohn's disease (CD) and ulcerative colitis (UC) activity indices were used to classify disease severity.
RESULTS: A total of 75 children (UC = 44, CD = 41; mean (SD) age at diagnosis 8.2 (3.5) years) were interviewed at mean age of 12.8 (2.7) years. Mean IMPACT-III score was significantly lower in children with more severe disease (mild: 71.8 (13.6) vs. moderate: 65.5 (10.9) vs. severe: 46.3 (14.5); P
OBJECTIVE: This study aimed to assess preoperative predictors for intraoperative IPAA and review management.
DESIGN: This is a retrospective review.
SETTING: This study was conducted at Cleveland Clinic between January 2010 and May 2018.
PATIENTS: Patients ≥18 years of age who underwent ileoanal pouch surgery were included. Patients with successful pouch creation as planned were grouped as "successful IPAA creation." Operative reports of patients who underwent alternative procedures were reviewed to identify cases when the pouch was preoperatively planned but intraoperatively abandoned (IPAA-abandoned group). Multivariate logistic regression models were developed to determine predictors of intraoperative pouch abandonment. We also reviewed the management of patients in whom the initial pouch creation failed.
MAIN OUTCOME MEASURES: The primary outcomes measured were preoperative predictors for intraoperative ileoanal pouch abandonment.
RESULTS: A total of 1438 patients were offered an ileoanal pouch; 21 (1.5%) experienced pouch abandonment due to inadequate reach (n = 17) and other technical reasons (n = 4). These patients underwent alternative procedures such as end or loop ileostomy with/without proctectomy. Multivariate logistic regression analysis indicated male sex (OR, 6.021; 95% CI, 1.540-23.534), BMI (OR, 1.217; 95% CI, 1.114-1.329), and a 2-stage procedure (OR, 14.510; 95% CI, 4.123-51.064) as independent factors associated with intraoperative abandonment of pouch creation. Alternative procedures were total proctocolectomy with end ileostomy (n = 14) and total abdominal colectomy with end ileostomy without proctectomy (n = 7). Ultimately, pouch creation was achieved in 6 of 21 patients after a median interval of 8.8 (range, 4.1-34.8) months. All patients had intentional weight loss before a reattempt and total abdominal colectomy with end ileostomy without proctectomy as their initial procedure.
LIMITATIONS: This study was limited by its retrospective nature.
CONCLUSIONS: Ileoanal pouch abandonment is rare and can be mitigated by initial total abdominal colectomy and weight loss. Male, obese patients are at a higher risk of failure. Intraoperative assessment of ileoanal pouch feasibility should occur before rectal dissection. See Video Abstract at http://links.lww.com/DCR/B156. PREDICCIÓN MULTIVARIANTE DEL ABANDONO INTRAOPERATORIO DE LA ANASTOMOSIS ANAL CON BOLSA ILEAL: La proctocolectomía total restaurativa con anastomosis de bolsa ileoanal puede no ser posible en algunos pacientes debido a limitaciones técnicas intraoperatorias.Evaluar los predictores preoperatorios para el abandono intraoperatorio de la bolsa ileoanal y revisar el manejo.Revisión retrospectiva.Cleveland Clinic entre Enero de 2010 y mayo de 2018.Pacientes > 18 años que se sometieron a cirugía de bolsa ileoanal. Los pacientes con una creación exitosa de la bolsa según lo planeado se agruparon como "creación exitosa de anastomosis de bolsa ileoanal". Se revisaron los informes operativos de los pacientes que se sometieron a procedimientos alternativos para identificar los casos en que la bolsa se planificó preoperatoriamente pero se abandonó intraoperatoriamente (grupo de "anastomosis anal de bolsa ileoanal abandonada"). Se desarrollaron modelos de regresión logística multivariante para determinar los predictores del abandono intraoperatorio de la bolsa. También revisamos el manejo de pacientes que fallaron en la creación inicial de la bolsa.Predictores preoperatorios para el abandono intraoperatorio de la bolsa ileoanal.A un total de 1438 pacientes se les ofreció una bolsa ileoanal; 21 (1.5%) experimentaron abandono de la bolsa debido a un alcance inadecuado (n = 17) y otras razones técnicas (n = 4). Estos pacientes se sometieron a procedimientos alternativos como ileostomía final o de asa con / sin proctectomía. El análisis de regresión logística multivariante indicó género masculino (OR, 6.021; IC 95%, 1.540-23.534), índice de masa corporal (OR, 1.217; IC 95%, 1.114-1.329) y procedimiento en 2 etapas (OR, 14.510; IC 95%, 4.123-51.064) como factores independientes asociados con el abandono intraoperatorio de la creación de la bolsa. Los procedimientos alternativos fueron la proctocolectomía total con ileostomía final (n = 14) y la colectomía abdominal total con ileostomía final sin proctectomía (n = 7). Finalmente, la creación de la bolsa se logró en 6/21 pacientes después de un intervalo medio de 8.8 (rango, 4.1-34.8) meses. Todos los pacientes tuvieron pérdida de peso intencional antes de la reintenta y colectomía abdominal total con ileostomía final sin proctectomía como procedimiento inicial.Naturaleza retrospectiva.El abandono de la bolsa ileoanal es raro y puede mitigarse mediante la colectomía abdominal total inicial y la pérdida de peso. Los pacientes masculinos y obesos tienen un mayor riesgo de fracaso. La evaluación intraoperatoria de la viabilidad de la bolsa ileoanal debe ocurrir antes de la disección rectal.

METHODS: Hospital Sultanah Aminah, Johor Bahru, is the only public hospital in Johor with a Gastroenterology service. Data on all existing and new IBD patients managed by the Gastroenterology Unit in 2016 were collected. Incidence and prevalence of IBD in 2016 were then calculated based on the estimated population of Johor and Johor Bahru.
RESULTS: Twenty-five new cases of IBD were diagnosed in 2016. Among the 25 cases, 13 cases were Crohn's disease (CD), 10 were ulcerative colitis (UC) and two were IBD Unclassified (IBDU). The crude incidence of IBD, CD, UC and IBDU were 0.68, 0.36, 0.27, and 0.05 per 100,000 population respectively. Ethnic Indians had the highest incidence of IBD at 4.21 followed by Malays and Chinese at 0.56 and 0.18 per 100,000 population respectively. A total of 156 IBD cases were captured. Amongst them, 85 cases were UC, 68 cases were CD and three cases were IBDU, hence the prevalence of IBD, UC, CD and IBDU were 4.27, 2.33, 1.86 and 0.08 per 100,000 population respectively. Similarly, Indians had the highest prevalence at 16.84, followed by Chinese at 4.06 and Malays at 3.44 per 100,000 population.
CONCLUSIONS: The incidence of IBD in Johor is comparable to that of a previous study in northern Peninsular Malaysia. The ethnicity preponderance is similar to the previous studies conducted in Malaysia.
