Background: A relation between abdominal obesity and colorectal tumor development has been reported repeatedly, and is believed to be more remarkable in man than in women. However, the details vary depending on scientific reports. This may be due at least partly to the selected surface anthropometric index in addition to the influence of gender and ethnic groups. To cope with this, we considered a new index of abdominal obesity and evaluated its risk prediction potential. Materials and Methods: Six hundred ninety five Japanese (262 women and 433 men) who had a colonoscopy were studied. The new index was named as waist circumference to height index (WHI) and was calculated by the formula of waist circumference (cm)/height (m)/height (m). Biochemical and lifestyle factors were investigated preceding the colonoscopy. Statistical analysis was performed using SPSS for Windows. Results: Increase of WHI was associated with altered metabolism of carbohydrate and lipid in both women and men. WHI was positively related with the development of colon tumor of women, while not with that of men. Logistic regression analysis performed for stratified age groups (45-54, 55-64 and 65-74 years) showed that WHI significantly increased odds ratio to 1.31 (CI 1.05-1.64 p=0.01) in women of 55-65 years. In contrast, in men this index WHI reduced the odds ratio insignificantly, while low density lipoprotein and triglyceride significantly increased the odds ratio to 1.01 (CI 1.00-1.03 p=0.02) in the 55-65 year group and to 1.02 (CI 1.00-1.03 p=0.02) in the 45-55 year group. Conclusions: In Japanese the risk factors for colon tumor development are different between women and men. WHI is a simple and efficient predictor of colon tumor risk in Japanese women and may be used to select those who should have colonoscopy.

We report an unusual case of a sigmoid colon perforation after ventriculoperitoneal shunt surgery. Distal catheters are known to cause perforation in the setting of colonoscopy. The exact pathogenesis of this complication is not clear, but it can cause serious complications. Hence, patients require prompt and aggressive management, including laparotomy with bowel wall repair, catheter removal, and antibiotic therapy.

Purpose: A descriptive study was conducted to identify awareness of information, emotional distress, behavioral distress, and perceived value of information in clients who were scheduled for endoscopic examinations, and to determine correlations between the variables. Method: Participants were 87 clients who were scheduled for endoscopic examinations; gastroscopy, bronchoscopy, and colonoscopy. The questionnaires were collected from September to December, 2002 by a trained nurse. Self reports, interviews, and observations were used. Data were analyzed with frequencies, percentages, means, Pearson correlation coefficients, ANOVA, and Scheffe post test using the SPSS/PC 9.0. Result: The score for awareness of information was 17.46, state anxiety was 47.26, emotional distress during exam was 2.90, behavioral distress was 11.18, and perceived value of information was 4.21, Clients aged above 60 showed significantly lower awareness of information than other groups. Clients undergoing broncoscopy reported significantly higher emotional distress during the ekam than subjects for colonoscopy. Clients undergoing gastroscopy showed significantly higher behavioral distress than any of the others. There were no relationships between awareness of information and anxiety, but, a significant positive relationship was found between anxiety and emotional distress during exam, between emotional distress and behavioral distress, and between awareness of information and perceived value of information. Conclusion: Awareness of information by the clients through provision of an educational booklet was low, and clients showed moderate level of state anxiety. Research studies are needed to compare providing information with other interventions for comfortable progress of endoscopic examinations. Especially specific strategies should be established for elderly clients to facilitate awareness of information.

Purpose: Even though the incidence of colorectal cancer (CRC) has increased in Korea, the colorectal cancer screening (CRCS) is lower than that of other cancer screenings. The purpose of this study was to identify CRCS rate and to predict factors in blue-color workers. Methods: A descriptive survey design was employed. Data were collected with 327 workers, recruited from 32 companies, aged 40 and over using questionnaire from August 2010 to January 2011. Collected information included CRCS, demographic characteristics, job characteristics, health behaviors, and interpersonal relationship. The definition of CRCS included fecal occult blood test (FOBT), colonoscopy, or double contrast barium enema (DCBE). Results: Among 94 workers receiving CRCS, workers having FOBT were 37, colonoscopy were 28, and DCBE was 6 in the past. Workers who aged over 50 (OR=2.30, 95% CI=1.11-4.77), middle school educated (OR=0.30, 95% CI=0.14-0.65), less working hours (OR=0.98, 95% CI=0.96- 0.99), and had family members who carried out regular cancer screening (OR=1.89, 95% CI=1.01-3.55) were more likely to perform CRCS. Conclusion: The findings suggest that the information and notice about CRCS to increase screening uptake, providing the accessible screening method, and involving company administrators or health managers might be useful to increase the CRCS rate in workers.

Background: Colorectal cancer is the third most common type of cancer in males and the second in females in Iran. Males are more likely to develop CRC than women and age is considered as a main risk factor for colorectal cancer. Prevalence of colorectal cancer has been increasing in Asian countries. Aim: The object of this study was to determine the clinical and pathology characteristics of colorectal polyps in Iranian patients and to investigate the variation between our populations with other populations. Materials and Methods: A total of 167 patients with colorectal polyps were included in our study. All underwent colonoscopy during 2009-2013 and specimens were taken through polypectomy and transferred to pathology. All data in patient files including pathology reports were collected and analyzed by SPSS 16 software. A two-tailed test was used and a P-value of < 0.05 was considered significant. Results: Mean age of participants was $57{\pm}15$. Some 84 were females (50.3%) and 83 males (49.7%). Total of 225 polyps were detected which 119 (52.9%) were in males and 106 (47.1%) were in females. Solitary polyps were observed in 124 patients (74%), 26 (15.6%) had two polyps and 17 (10.1%) with more than two polyps (three to five). Rectosigmoid was the site of most of the polyps (63.1%), followed by 19.6% in the descending colon, 7.6% in the transverse, 5.8% in the ascending, and 3.1% in the cecum, data being missing in two cases. Conclusions: Recto sigmoid was site of most of the polyps. The most prevalent type of lesion was adenomatous polyps detected in 78 (34.7%). Mixed hyperplastic adenomatous type observed in 70 (31.1%). This high prevalence of adenomatous polyps in Iranian patients implies the urgent need for screening plans to prevent further healthcare problems with colorectal cancer in the Iranian population.

Background: Colorectal cancer is a major cause of morbidity and mortality throughout the world. Colorectal cancer screening is an optimal way for reducing of morbidity and mortality and a clinical decision support system (CDSS) plays an important role in predicting success of screening processes. DSS is a computer-based information system that improves the delivery of preventive care services. The aim of this article was to detail engineering of information requirements and work flow design of CDSS for a colorectal cancer screening program. Materials and Methods: In the first stage a screening minimum data set was determined. Developed and developing countries were analyzed for identifying this data set. Then information deficiencies and gaps were determined by check list. The second stage was a qualitative survey with a semi-structured interview as the study tool. A total of 15 users and stakeholders' perspectives about workflow of CDSS were studied. Finally workflow of DSS of control program was designed by standard clinical practice guidelines and perspectives. Results: Screening minimum data set of national colorectal cancer screening program was defined in five sections, including colonoscopy data set, surgery, pathology, genetics and pedigree data set. Deficiencies and information gaps were analyzed. Then we designed a work process standard of screening. Finally workflow of DSS and entry stage were determined. Conclusions: A CDSS facilitates complex decision making for screening and has key roles in designing optimal interactions between colonoscopy, pathology and laboratory departments. Also workflow analysis is useful to identify data reconciliation strategies to address documentation gaps. Following recommendations of CDSS should improve quality of colorectal cancer screening.
