BACKGROUND/AIMS: Uninsured individuals have lower rates of screening colonoscopy (SC), and little is known regarding the pathology results obtained when they undergo colonoscopies. Since 2004, we have participated in a program that offers SC to uninsured New Yorkers; herein, we report our findings. METHODS: Uninsured, average-risk patients who were at least 50 years of age underwent SC at our institution between April 2004 and June 2011. We analyzed polyp pathology, location, size, incidence of adenomas, and incidence of adenomas with advanced pathology (AAP) with respect to ethnicity, gender, and age. RESULTS: Out of 493 referrals, 222 patients completed the colonoscopies. Polyps were identified in 21.2% of all patients; 14% had adenomas, and 4.5% had AAP. The rates of adenomas among African-Americans, Hispanics, and Whites were 24.3%, 12.1%, and 11.6%, respectively, and the corresponding rates of AAP were 10.8%, 3.5%, and 2.3%. Differences in the polyp type, location, and AAP did not reach statistical significance with respect to ethnicity or gender. Patients aged 60 and older were found to have a higher rate of advanced adenomas compared with younger patients (8.6% vs 2.6%, p=0.047). CONCLUSIONS: Further efforts to fund screening colonoscopies for uninsured individuals will likely result in the identification of advanced lesions of the colon before they progress to colorectal cancer.

OBJECTIVETo evaluate the colorectal cancer incidence among compliers and non-compliers in the population of colorectal cancer screening area, and to provide scientific basis for health economic evaluation of cancer screening.
METHODSBy screening different years build queue, to retrospectively compare the data of colorectal cancer screening from January 1, 2008 to December 31, 2013 and the data of cancer registration, and to analyze the colorectal cancer incidence rates among screening compliers and non-compliers, and to compare the average intervals between the end of screening and clinical cancer diagnosis using SPSS 19 statistical software. Mantel-Haenszel test was performed with a statistical significance level of α = 0.05.
RESULTSThe non-compliance rate was 38.24% among males and 28.49% among females (P < 0.001). The non-compliance rate was highest in the 40-44 and 70-74 years age groups and lowest in the 50-59 years age group. The compliers of the screening were followed up for 476,049 person-years, and there were 51 cases of colorectal cancer, with an incidence rate of 10.71/100,000. The non-compliers of the screening were followed up for 259 183 person-years, and there were 66 cases of colorectal cancer, with an incidence rate of 25.46/100,000, which was 1.38 times higher than that of the compliance group (χ2 = 21.699, P < 0.001). The incidence rate of colorectal cancer among subjects who were positive in initial screening but refused to receive an electronic colonoscopy was as high as 164.40/100,000, and the average delay time was 20.8 ± 16.8 months.
CONCLUSIONSThe colorectal cancer screening adherence among women is better than among men, and that of 50-54 years and 55-59 years age groups is better than in other age groups. The subsequent incidence rate of colorectal cancer in the non-compliance group is significantly higher than that of the compliance population.

Objective: To analyze the effect of colorectal cancer screening in the general population in Guangzhou, and provide evidence for the for development of colorectal cancer screening policy and strategy. Methods: The data of colorectal cancer screening in Guangzhou during 2015- 2016 were collected. The participation, the positive rate of fecal occult blood test, the detection rate of colonoscopy and screening effect of colonoscopy were evaluated. Results: A total of 220 834 residents aged 50-74 years received the screening, and the positive rate of the screening was 16.77% (37 040 cases). Colonoscopy was performed for 7 821 cases (21.12%). Colorectal lesions were found in 4 126 cases (52.76%), of which 614 (7.85%) and 73 (0.93%) and 230 (2.94%) were identified as advanced adenoma, severe dysplasia lesions and colorectal cancers, respectively. The detection rates of all colorectal lesions were higher in men than in women (all P<0.01). The diagnostic rate of early lesion was 87.24%, and 99 early cancer cases were found, accounting for 46.26% of the total cases. The overall screening detection rate of colorectal cancer was 104.15/100 000, higher than the incidence rate (81.18/100 000) in colorectal cancer surveillance (P<0.001), but age group <70 years had higher detection rate, age group ≥70 years had higher incidence rate. Conclusions: The colorectal cancer screening strategy in Guangzhou is effective in the detection of the population at high risk, increase the detection rate of colorectal lesions, early diagnosis rate of precancerous lesions and diagnosis rate of early colorectal cancer. The benefit in those aged ≤69 years was more obvious than that in those aged 70-74 years. It is necessary to improve the compliancy of colorectal cancer screening in population at high risk.

BACKGROUND/AIMS: The landscape of sedation for gastrointestinal (GI) endoscopic procedures and the nature of the procedures themselves have changed over the last decade. In this study, an attempt is made to analyze the frequency and etiology of all major adverse events associated with GI endoscopy. METHODS: All adverse events extracted from the electronic database and local registry were analyzed. Although the data analysis was retrospective, the adverse events themselves were documented prospectively. These events were evaluated after subdivision into propofol-based anesthesia and intravenous conscious sedation groups. RESULTS: Cardiorespiratory events, including cardiac arrest, were the most common adverse events during esophagogastroduodenoscopy, while bleeding was more frequent in patients undergoing colonoscopy. Pancreatitis was the most frequent adverse event in patients undergoing endoscopic retrograde cholangiopancreatography. The frequencies of most adverse events were significantly higher in patients anesthetized with propofol. Automatic regression modeling showed that the type of sedation, the American Society of Anesthesiologists physical status classification, and the procedure type were some of the predictors of immediate life-threatening complications. CONCLUSIONS: Clearly, our regression modeling suggests a strong association between the type of sedation as well as various patient factors and the frequency of adverse events. The possible reasons for our results are the changing demographics, the worsening comorbidities of the patient population, and the increasing technical complexity of these procedures. Although extensive use of propofol has increased patient satisfaction and procedure acceptability, its use is also associated with more frequent adverse events.

BACKGROUND/AIMS: This study sought to characterize the current sedation practices of Korean endoscopists in real-world settings. METHODS: All active members of the Korean Society of Gastrointestinal Endoscopy were invited to complete an anonymous 35-item questionnaire. RESULTS: The overall response rate was 22.7% (1,332/5,860). Propofol-based sedation was the dominant method used in both elective esophagogastroduodenoscopy (55.6%) and colonoscopy (52.6%). The mean satisfaction score for propofol-based sedation was significantly higher than that for standard sedation in both examinations (all p<0.001). The use of propofol was supervised exclusively by endoscopists (98.6%). Endoscopists practicing in nonacademic settings, gastroenterologists, or endoscopists with <10 years of endoscopic practice were more likely to use propofol than were their counterparts (all p<0.001). In total, 27.3% of all respondents performed sedation practices without having undergone sedation training, and 27.4% did so without any formal sedation protocols. The choice of propofol as the dominant sedation method was the only significant predictor of endoscopist experience with serious sedation-related adverse events (odds ratio, 1.854; 95% confidence interval, 1.414 to 2.432). CONCLUSIONS: Endoscopist-directed propofol administration is the predominant sedation method used in Korea. This survey strongly suggests that there is much room for quality improvement regarding sedation training and patient vigilance in endoscopist-directed sedation.

OBJECTIVETo evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for gastrointestinal disorders.
METHODSRetrospective analysis of the clinical data of 406 patients who underwent FMT from May 2014 to April 2016 in the Intestinal Microenvironment Treatment Centre of Nanjing General Hospital was performed, including patients with constipation(276 cases), recurrent Clostridium Difficile infection (RCDI, 61 cases), ulcerative colitis(44 cases), irritable bowel syndrome (15 cases) and Crohn's disease(10 cases). Donors were completely unrelated, 18- to 50-year-old non-pregnant healthy adult, with healthy lifestyle and habits, without taking antibiotics, probiotics and other probiotics history within 3 months. There were three routes of FMT administration: patients received 6 days of frozen FMT by nasointestinal tube placed in the proximal jejunum under gastroscope (319 cases); patients received capsules FMT per day for 6 consecutive days (46 cases) or once 600 ml of treated fecal liquid infusion into colon and terminal ileum by colonoscopy(41 cases).
RESULTSClinical cure rate and improvement rate of different diseases receiving FMT were respectively as follows: RCDI was 85.2% (52/61) and 95.1%(58/61); constipation was 40.2%(111/276) and 67.4%(186/276); ulcerative colitis was 34.1%(15/44) and 68.2% (30/44); irritable bowel syndrome was 46.7% (7/15) and 73.3% (11/15) and Crohn disease was 30.0%(3/10) and 60.0%(6/10). RCDI had the best efficacy among these diseases(P<0.01). There was no significant difference between the three routes of FMT administration(P=0.829). The clinical cure rate and improvement rate of different routes were 43.3%(138/319) and 58.6% (187/319) respectively in nasogastric transplantation group, 41.5%(17/41) and 61.0%(25/41) in colonoscopy group, 37.0%(17/46) and 63.0% (29/46) in the capsule transplantation group. There was no serious adverse event during the follow-up. The most common side effects were respiratory discomfort (27.3%, 87/319) and increased venting (51.7%, 165/319) in nasogastric transplantation group. Diarrhea was the most common complication in colonoscopy group (36.6%, 15/41). The main symptoms were increased venting (50.0%, 23/46) and nausea(34.8%, 16/46) in oral capsule group. Side effect symptoms disappeared after the withdraw of nasogastric tube, or at the end of treatment, or during hospitalization for 1-3 days.
CONCLUSIONSFMT is effective for many gastrointestinal disorders. No significant adverse event is found, while the associated mechanism should be further explored.
