This study aimed to elucidate the prevalence of hepatitis B virus (HBV) serologic markers in Korean patients newly diagnosed with, but not yet treated for inflammatory bowel disease (IBD).
We prospectively enrolled 210 patients newly diagnosed with IBD (109 with ulcerative colitis and 101 with Crohn's disease). Hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core antibody (anti-HBc) levels were measured and compared with those of 1,100 sex- and age-matched controls.
The prevalence of chronic HBV infection (positive HBsAg, positive anti-HBc, and negative anti-HBs results) and past infection (negative HBsAg, positive anti-HBc, and positive or negative anti-HBs results) were not significantly different between the patients and controls (chronic HBV infection: IBD, 3.8% vs. control, 4.9%,
The patients newly diagnosed with IBD were susceptible to HBV infection. The frequency of nonimmunity was high, especially in the patients aged <20 years and those with a longer duration of symptoms before diagnosis. Therefore, it is necessary to screen for HBV serologic markers and generate a detailed vaccination plan for patients newly diagnosed with IBD.

This study aimed to compare the clinical characteristics and management patterns of inflammatory bowel disease (IBD) patients in a secondary hospital (SH) with those in tertiary referral centers (TRC).
Data from IBD patients in SH and 2 TRCs were retrospectively reviewed. The cumulative thiopurine use rate was compared between hospitals after controlling for different baseline characteristics using propensity score matching.
Among the total of 447 patients with IBD, 178 Crohn's disease (CD) and 269 ulcerative colitis (UC) patients were included. Regarding initial CD symptoms, patients from SH were more likely to show perianal symptoms, such as anal pain or discharge (56.6% vs. 34.3%,
The clinical characteristics and management of the IBD patients in SH were substantially different from those in TRCs. Thiopurine treatment was less commonly used for SH patients.

Establishment of a colonoscopy reporting system is a prerequisite to determining and improving quality. This study aimed to investigate colonoscopists' opinions and the actual situation of a colonoscopy reporting system in a clinical practice in southeastern area of Korea and to assess the factors predictive of an inadequate reporting system.
Physicians who performed colonoscopies in the Daegu-Gyeongbuk province of Korea and were registered with the Korean Society of Gastrointestinal Endoscopy (KSGE) were interviewed via mail about colonoscopy reporting systems using a standardized questionnaire.
Of 181 endoscopists invited to participate, 125 responded to the questionnaires (response rate, 69%). Most responders were internists (105/125, 84%) and worked in primary clinics (88/125, 70.4%). Seventy-one specialists (56.8%) held board certifications for endoscopy from the KSGE. A median of 20 colonoscopies (interquartile range, 10–47) was performed per month. Although 88.8% of responders agreed that a colonoscopy reporting system is necessary, only 18.4% (23/125) had achieved the optimal reporting system level recommended by the Quality Assurance Task Group of the National Colorectal Cancer Roundtable. One-third of endoscopists replied that they did not use a reporting document for the main reasons of "too busy" and "inconvenience." Non-endoscopy specialists and primary care centers were independent predictive factors for failure to use a colonoscopy reporting system.
The quality of colonoscopy reporting systems varies widely and is considerably suboptimal in actual clinical practice settings in southeastern Korea, indicating considerable room for quality improvements in this field.

Despite the rising incidence and prevalence of inflammatory bowel disease (IBD) in Asian populations, data regarding clinical characteristics of patients in Asia based on age at diagnosis are relatively sparse. The aim of this study was to compare clinical characteristics based on the age at diagnosis according to the Montreal Classification in Korean IBD patients.
We recruited consecutive patients with IBD at two tertiary hospitals and retrospectively reviewed their medical information. Patients were divided into three groups according to their age at diagnosis: youth (<17 years), young adult (17-40 years), and middle-old (>40 years). The main clinical characteristics for comparison were the achievement of a remission state at the last follow-up visit, cumulative rate of surgery, and cumulative use of immunomodulators and tumor necrosis factor-α (TNFα) blockers during the follow-up period.
In total, 346 IBD patients were included (Crohn's disease [CD] 146 and ulcerative colitis 200; 36 youth, 202 young adult, and 113 middle-old). The middle-old group with CD was characterized by a predominance of uncomplicated behavior (
Age at diagnosis according to the Montreal Classification is an important prognostic factor for Korean IBD patients.

Given the characteristic procedures involved in the endoscopy unit, the spread of pathogens is much more frequent in this unit than in other environments. However, there is a lack of data elucidating the existence of pathogens in the endoscopy unit. The aim of this study was to detect the presence of possible pathogens in the endoscopy unit.
We performed environmental culture using samples from the endoscopy rooms of 2 tertiary hospitals. We used sterile cotton-tipped swabs moistened with sterile saline to swab the surfaces of 197 samples. Then, we cultured the swab in blood agar plate. Samples from the colonoscopy room were placed in thioglycollate broth to detect the presence of anaerobes. After 2 weeks of culture period, we counted the colony numbers.
The most commonly contaminated spots were the doctor's keyboard, nurse's cart, and nurse's mouse. The common organisms found were non-pathogenic bacterial microorganisms
Although the organisms detected in the endoscopy unit were mainly non-pathogenic organisms, they might cause opportunistic infections in immunocompromised patients. Therefore, the environment of the endoscopy room should be managed appropriately; moreover, individual hand hygiene is important for preventing possible hospital-acquired infections.
