Background/Aims
Colorectal cancer incidence among patients aged ≤50 years is increasing. This study aimed to develop and validate an advanced colorectal neoplasm (ACRN) screening model for young adults aged <50 years in Korea.
Methods
This retrospective cross-sectional study included 59,575 consecutive asymptomatic Koreans who underwent screening colonoscopy between 2003 and 2012 at a single comprehensive health care center. Young Adult Colorectal Screening (YCS) score was developed as an optimized risk stratification model for ACRN using multivariate analysis and was internally validated. The predictive power and diagnostic performance of YCS score was compared with those of Asia-Pacific Colorectal Screening (APCS) and Korean Colorectal Screening (KCS) scores.
Results
41,702 and 17,873 subjects were randomly allocated into the derivation and validation cohorts, respectively, by examination year. ACRN prevalence was 0.9% in both cohorts. YCS score comprised sex, age, alcohol, smoking, obesity, glucose metabolism abnormality, and family history of CRC, with score ranges of 0 to 10. In the validation cohort, ACRN prevalence was 0.6% in the low-risk tier (score, 0–4), 1.5% in the moderate-risk tier (score, 5–7), and 3.4% in the high-risk tier (score, 8–10). ACRN risk increased 2.5-fold (95%CI, 1.8–3.4) in the moderate-risk tier and 5.8-fold (95%CI, 3.4–9.8) in the high-risk tier compared with the low-risk tier. YCS score identified better balanced accuracy (53.9%) than APCS (51.5%) and KCS (50.7%) scores and had relatively good discriminative power (area under the curve=0.660).
Conclusions
YCS score based on clinical and laboratory risk factors was clinically effective and beneficial for predicting ACRN risk and targeting screening colonoscopy in adults aged <50 years.

<b>Background/Aims</b><br/>

To prevent the transmission of pathogens by endoscopes, following established reprocessing guidelines is critical. An ideal reprocessing step is simple, fast, and inexpensive. Here, we evaluated and compared the efficacy and safety of two disinfectants, a tertiary amine compound (TAC) and ortho-phthalaldehyde (OPA).

Methods

A total of 100 colonoscopes were randomly reprocessed using two same automated endoscope reprocessors, according to disinfectant. The exposure time was 10 minutes for 0.55% OPA (Cidex® OPA, Johnson & Johnson) and 5 minutes for 4% TAC (Sencron2®, Bab Gencel Pharma & Chemical Ind. Co.). Three culture samples were obtained from each colonoscope after reprocessing.

Results

A total of nine samples were positive among the 300 culture samples. The positive culture rate was not statistically different between the two groups (4% for OPA and 2% for TAC, P=0.501). There were no incidents related to safety during the study period.

Conclusions

TAC was non-inferior in terms of reprocessing efficacy to OPA and was safe to use. Therefore, TAC seems to be a good alternative disinfectant with a relatively short exposure time and is also less expensive than OPA.

<b>Background/Aims</b><br/>

Quality of life is closely related to anemia in patients with inflammatory bowel disease (IBD). Several studies have reported on anemia in patients with IBD in Western countries. This study investigated the prevalence and clinical characteristics of anemia in Korean patients with IBD.

Methods

We reviewed the medical records of 92 patients with ulcerative colitis (UC) and 76 patients with Crohn's disease (CD) who were followed regularly at a single tertiary medical center in Korea between January 2003 and December 2012. Hemoglobin (Hb) thresholds used to define anemia were <13.0 g/dL in men and <12.0 g/dL in women according to the World Health Organization criteria. We chose the lowest Hb level in each year as a representative value because Hb levels changed at each examination and anemia was associated with disease deterioration. The relationship between clinical variables and lowest Hb level was assessed.

Results

The prevalence of anemia was 36.3% in patients with UC and 41.6% in patients with CD. Anemia in patients with CD was associated with hospital admission, 5-aminosalicylate (5-ASA) and infliximab treatment in men. Anemia in patients with UC was associated with hospital admission, oral steroid use, thiopurine and infliximab treatment in men.

Conclusions

The prevalence of anemia in Korean patients with IBD was comparable to that of patients in Western countries. Anemia was associated with male patients with CD who were admitted to the hospital and received medications including 5-ASA and infliximab, and men with UC who were admitted to the hospital and received medications including oral steroids, thiopurine and infliximab.

AbstractAbstract PDF
Background/Aims
A subset of patients may develop colorectal cancer after a colonoscopy that was negative for carcinoma. These missed or de novo developed lesions were termed as interval cancers. Many studies regarding interval cancer have been conducted in Western countries, whereas very limited data are available in Asian populations. Therefore, the purpose of this study was to investigate prevalence, clinicopathologic features, and predictors of interval colorectal cancers in the Korean population. Methods: Interval cancer was defined as a cancer that is diagnosed within 5 years of a negative colonoscopy result. Among the patients who were diagnosed colorectal cancers at Kangbuk Samsung Hospital from January 2007 to April 2012, clinicopathologic characteristics of interval cancers were compared with those of sporadic cancers. Results: Among the 785 patients, 482 responded to telephone calls. Of these, 30 (6.2%) developed interval cancers. Finally, 28 patients who had interval cancers were compared with 415 patients who had sporadic cancers. Interval cancer group was significantly younger and more frequent in the right side colon than sporadic cancer group. There was no differences in sex, tumor size, differentiation, and staging between two groups. In multivariate analysis, young age and right side colon cancer were independent factors associated with an interval cancer. Conclusions: A significant proportion of Korean patients developed interval colorectal cancer, especially at the young age and in the proximal colon. (Intest Res 2013;11:178-183)

Exposure to Diagnostic Radiation in Patients with Inflammatory Bowel Disease: A Single Center Study
Jae Wan Lim, Yoon Suk Jung, Jung Ho Park, Hong Joo Kim, Yong Kyun Cho, Chong Il Sohn, Woo Kyu Jeon, Byung Ik Kim, Dong Il Park
Intest Res 2013;11(2):107-112.   Published online April 30, 2013
DOI: https://doi.org/10.5217/ir.2013.11.2.107
AbstractAbstract PDF
Background/Aims
Western studies recently reported that patients with inflammatory bowel disease (IBD) are exposed to diagnostic radiation at potentially harmful levels. There is little research, however, on exposure to diagnostic radiation in patients with IBD in Asian areas. The present study assessed cumulative radiation exposure dose in patients with IBD who were treated at a single-tertiary medical center in Korea and analyzed the factors that increased the exposure dose. Methods: Retrospective investigation was performed of the medical records of the patients who were followed up for 1 year or more in a period from January 2003 through November 2011 at Kangbuk Samsung Hospital. Results: Included in the study were 202 patients with IBD: 80 (39.6%) had Crohn's disease (CD) and 122 (60.4%) had ulcerative colitis (UC). The mean follow-up period was 4.2±2.5 years for CD and 4.3±1.4 years for UC. The mean culmulative effective dose (CED) for CD and UC were 39.7 and 11.0 mSv respectively (P<0.001). In CD, factors associated with increased CED were surgery, history of intravenous steroid treatment, and structuring or penetrating disease. Conclusions: A substantial proportion of IBD patients, especially CD patients, were exposed to significantly harmful amounts of diagnostic radiation, mainly due to computed tomography examination. Efforts should be made to reduced diagnostic medical radiation, especially in patients at risk for increased radiation exposure. (Intest Res 2013;11:107-112)

AbstractAbstract PDF
Background/Aims
Conflicting data have been reported about the seasonal variation in flare-up of inflammatory bowel disease (IBD). The aim of this study was to assess the occurrence of seasonal variations in flare-up of IBD in the Korean population. Methods: Patients with IBD, who underwent more than 1 year of follow-up and showed more than 1 episode of flare-up, were included. Flares of disease were refined as follows; receipt of a new prescription and increasing dose of corticosteroids, 5-ASA or immunosuppressant; hospitalized or operated due to development and worsening of symptoms; elevation of inflammatory marker due to worsening of Crohn's Disease Activity Index (CDAI) or Mayo score. In addition, for patients with more than two episodes of flare-up, they were investigated in a monthly and seasonal pattern. Results: Of 573 patients with IBD, 46 patients with Crohn's disease and 61 patients with ulcerative colitis were enrolled. There was no association between month of the year and flare of Crohn's disease (P=0.06) or ulcerative colitis (P=0.58). Further, no association between season of the year and flare of Crohn's disease (P=0.06) or ulcerative colitis (P=0.68). However, in Crohn's disease who experience 2 or more flare-ups, symptoms occurred more frequently during winter, especially December (P=0.029). Conclusions: In the Korean population, there was no association of seasonal and monthly variation in flares of Crohn's disease and ulcerative colitis. However, in Crohn's disease, individuals with 2 flar-up or more, symptoms occurred more frequently during December. (Intest Res 2012;10: 0-167)

A Case of Pulmonary Tuberculosis Misdiagnosed as Lung Metastases after Curative Resection of Early Colon Cancer
Chang Joon Kim, Dong Il Park, Sung Keun Park, Jung Ho Park, Chong Il Sohn, Woo Kyu Jeon, Young-Ho Kim, Sun-Young Lee
Intest Res 2007;5(2):196-199.   Published online December 30, 2007
AbstractAbstract PDF
Early colon cancer can be cured by endoscopic mucosal resection (EMR). However, the possibility of complete resection depends on the depth of cancer invasion. Ten percent of cancers invading the submucosal layer are associated with local lymph node metastasis. Therefore, colon cancers confirmed to invade the submucosal layer after EMR require surgical resection. We treated a woman with adenocarcinoma at the hepatic flexure with submucosal invasion diagnosed after piecemeal EMR. Subsequent right hemicolectomy with lymph node dissection revealed no residual cancer. However, after 21 months, multiple pulmonary nodules were incorrectly diagnosed as pulmonary metastases, based on the radiological findings. The final diagnosis of pulmonary tuberculosis was made after lung metastasectomy. (Intest Res 2007;5:196-199)
