The association between rectosigmoid polyps and polyps in the more proximal colon is still a matter of debate, and the need for colonoscopy in patients with rectosigmoid polyps that are detected by flexible sigmoidoscopy is controversial. The aim of this study was to determine whether or not certain characteristics of rectosigmoid polyps are associated with the presence and characteristics of proximal colonic polyps. Seven hundred and twenty-eight patients who underwent total colonoscopy between October 1995 and June 1998 and who had colorectal polyps were retrospectively analyzed. Patients with inflammatory bowel diseases, familial adenomatous polyposis, or any advanced cancer were excluded. The odds ratio (OR) and 95% confidence interval (CI) of prevalence of proximal colonic polyps according to the patients age and sex, as well as the characteristics of rectosigmoid polyps, were calculated. Advanced adenoma was defined as an adenoma larger than 10 mm or an adenoma of any size with villous component, high-grade dysplasia or invasive carcinoma. Among 728 patients with colorectal polyps, 356 patients (48.9%) had polyps only in the rectosigmoid region, 193 patients (26.5%) had polyps only in the proximal colon, and 179 patients (24.6%) had polyps in both the rectosigmoid and proximal colon. In 535 patients with rectosigmoid polyps, the prevalence of proximal colonic polyps, neoplastic polyps and advanced adenomas were 33.4%, 27.3% and 2.9%, respectively. The prevalence of proximal colonic polyps in patients with rectosigmoid polyps was found to be significantly related to the male gender and elderly patients, in addition to the neoplastic histology of the rectosigmoid polyps. However, the prevalence of the proximal colonic polyps was not related to the size, number and shape of rectosigmoid polyps. In 179 patients with both rectosigmoid and proximal colonic polyps, the characteristics of proximal colonic polyps such as size, number and shape were similar to those of rectosigmoid polyps. We recommend total colonoscopic examination in all patients with rectosigmoid adenomas, regardless of the size, number, and shape, especially in elderly males.

Objective: To explore the correlation between eosinophils (Eos) and the incidence of chronic sinusitis with nasal polyps (CRSwNP) in Xinjiang region of China by comparing the proportion of inflammatory cells in the pathological tissues and peripheral blood. Methods: Retrospective analysis was performed on 582 patients with CRSwNP who underwent endoscopic nasal surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2012 to March 2018, including 367 males and 215 females, aged (45.5±13.4) years (x¯±s). Patients were divided into groups according to demographic characteristics, recurrence and complication of allergic rhinitis (AR). Preoperative blood routine and postoperative pathological section data of nasal polyps were collected to compare the ratio of inflammatory cells in pathological tissue and the ratio of peripheral blood Eos in each group. The correlation between the proportion of inflammatory cells in the pathological tissue of nasal polyps and the recurrence of CRSwNP was analyzed, as well as the distribution of (eosCRSwNP) in Uygur and Han CRSwNP patients in Xinjiang region. Statistical analysis was performed by SPSS 19.0 software. Results: Compared with non-recurrent CRSwNP patients, the ratio of Eos in nasal polyp tissue and peripheral blood was increased significantly, (Z value was -3.142 and -2.344, respectively, both P<0.05). Compared with CRSwNP patients without AR, the ratio of Eos in nasal polyps and peripheral blood was also increased significantly in patients with AR (Z value was -6.664 and -4.520, respectively, both P<0.05). There was a positive correlation between tissue Eos and CRSwNP recurrence (r=0.130, P=0.002). The majority of CRSwNP patients were both eosCRSwNP in Uygur and Han ethnic groups. Conclusions: Eos is associated with the recurrence of CRSwNP in Xinjiang region, and eosCRSwNP is the dominant factor in both Uygur and Han patients.

BACKGROUD/AIMS: Obesity is a rising problem in industrialized countries. Numerous epidemiologic studies have shown a positive association between obesity and colorectal polyps. There are few studies investigating the association between colorectal adenomatous polyps and body fat composition in Korea. We tried to examine the relationship between body fatness and colorectal adenomatous polyps in health check-up subjects in Korea. METHODS: Six thousand seven hundred and six routine health check-up subjects, who visited our hospital between March 2002 and April 2005 and underwent distal colon examimation with sigmoidoscopy, were enrolled in this study. Among them, colonoscopy was done in 860 patients to evaluate the entire colon. We tried to reveal the relationship between body mass index (BMI) and size, location, number and histopathological type of polyps. BMI was used as an indicator of obesity. RESULTS: The mean value of BMI in total polyp-free group (23.8+/-2.9) was not different from that of the polyp group (24.5+/-2.8, p=0.09). The frequency of rectosigmoid polyps in obese patients (20.4%) was higher than that in non-obese patients (16.0%, p<0.05). The frequency of adenomatous polyp was not different between obese and non-obese group. Number of polyps (> or =4) correlated well with obesity. Moreover, age and triglyceride level in patients with colonic adenoma were significantly higher than in patients without colonic adenom. CONCLUSIONS: This study shows that obesity is not associated with colonic adenomatous polyp in Korean population. However, we observed that obesity may be associated with rectosigmoid colon polyps. Furthermore, age and triglyceride level might be the risk factors of colonic adenomatous polyps in Korean population.

OBJECTIVE: To investigate the endoscopic and pathological characteristics of gastric adenomatous polyps and to assess the potential risk factors for canceration of gastric adenomatous polyps. METHODS: The endoscopic and pathological characteristics of the patients with gastric adenomatous polyps from January 1, 2005 to December 31, 2019 were summarized retrospectively, and the risk factors of canceration were analyzed. RESULTS: A total of 125 patients with gastric adenomatous polyps were included, 51.20% of whom were females. The average age was (66.7±12.3) years. 64.80% of patients with gastric adenomatous polyps equal or more than 65 years old, and only 5.60% of the patients less than 45 years old. Adenomatous polyps were mostly distributed in the corpus and antrum with 40.80% and 32.80%, respectively. The majority of them were single (90.40%) and sessile (76.81%). 65.4% of adenomatous polyps were no more than 1.0 cm in diameter, and 23.20% of patients with adenomatous polyps were combined with hyperplastic polyps and/or fundus glandular polyps, and 1.60% had both pathological types of polyps. 58.62% (17/29) patients with hyperplastic polyps and/or fundus glandular polyps had multiple polyps. 1.60% (2/125) of the patients had gastric neuroendocrine tumor of G1 stage. Synchronous gastric cancer was detected in 13.60% (17/125) of the patients with adenomatous polyps, and the proportion of low-grade intraepithelial neoplasia was 18.40% (23/125). The main types of synchronous gastric cancer were progressive (70.59%) and undifferentiated (66.67%). Chronic atrophic gastritis with intestinal metaplasia was found in 52.80% of the patients, and autoimmune gastritis accounted for 11.20%. The positive rate of Helicobacter pylori was 21.60%. The canceration rate of gastric adenomatous polyps was 20.80%. The cancer was mainly differentiated, but there was sigmoid ring cell carcinoma as well. Diameter of >1.0 cm (OR=5.092, 95%CI: 1.447-17.923, P=0.011), uneven surface morphology and erosion (OR=13.749, 95%CI: 1.072-176.339, P=0.044) were independent risk factors of adenomatous polyps. CONCLUSION The synchronous gastric cancer is common and the canceration of gastric adenomatous polyps is high with diameter and surface morphology as independent risk factors. We should pay attention to the identification of the pathological types of polyps and the evaluation of the whole gastric mucosa during the endoscopic examination.

BACKGROUND/AIMS: Although there are various reports on the prevalence of gallbladder (GB) polyp according to the race or area, there is no report on Daegu and Gyeongbuk provinces. Therefore, we investigated the prevalence and related risk factors of GB polyp in health screening population of Daegu and Gyeongbuk provinces. METHODS: Of 28,911 adult health screening examinees from January 1997 to May 2003, age and gender-matched 8,008 (3,896 men, 4,112 women) were randomly selected to evaluate the prevalence. Independent risk factors were analyzed by comparing various variables between the GB polyp positive and negative groups. RESULTS: The prevalence of GB polyp was 2.2% (175/8,008). Those were 2.7% (104/3,896) among men and 1.7% (71/4,112) among women. Independent risk factors related with GB polyp were male gender (OR 1.434, p<0.001), obesity (OR 1.237, p=0.024), and hepatitis B carrier (OR 1.888, p<0.001) CONCLUSIONS: Prevalence of GB polyp in Daegu and Gyeongbuk provinces is 2.2%. Male, obesity, and hepatitis B carrier may be the risk factors related with GB polyp in this region.

The correlation between chronic constipation and colorectal neoplasms has been arousing wide interest. There have been a number of domestic and international epidemiological and clinical researches focusing on this issue. Based on these researches, the correlation between constipation and colorectal neoplasms was studied from three aspects: constipation and colorectal polyps; constipation and colorectal cancer; melanosis coli (MC), laxatives and colorectal neoplasms. We find that constipation can significantly increase the incidence of colorectal polyps and constipation does not significantly increase the incidence of colorectal cancer but is one of the risk factors for colorectal cancer. In addition, MC, laxatives and the incidence of colorectal polyps are also closely correlated. Given the fact that colorectal polyps are precancerous lesions, patients with long-term constipation should take less anthraquinone laxatives, and those with colorectal polyps should be followed up periodically.

OBJECTIVETo explore the health-related quality of life (QOL) status of patients with chronic rhinosinusitis and nasal polyps.

METHODSOne hundred and twenty patients with chronic rhinosinusitis and nasal polyps and two hundred individuals passing health examination were enrolled by random and their QOL scores were assessed by using QOL instruments including existing SF-36 questionnaire (Chinese version ) and SNOT-20 questionnaire translated into Chinese, of which clinimetric and psychometric properties were tested.

RESULTSThe feasibility, reliability, validity, and responsibility of Chinese version of SNOT-20 questionnaire all passed the test. By the assessment of SF-36 questionnaire, it revealed that scores of six domains such as physical functioning, role physical, bodily pain, mental health, vitality, and general health from patients with chronic rhinosinusitis and nasal polyps were lower than that of control group except social functioning and role emotional (P < 0.05). It showed by Chinese version of SNOT-20 questionnaire that patients exceeded healthy individuals in the scores of twenty items of three domains including physical problems, functional limitations, and emotional consequences, of which the most five important items affecting health status were respectively need to blow nose, thick nasal discharge, lack of a good night's sleep, dizziness, and post-nasal discharge (P < 0.05).

CONCLUSIONSQOL instruments such as Chinese version of SF-36 and SNOT-20 questionnaires can effectively differentiate the QOL status between patients with chronic rhinosinusitis and nasal polyps and healthy individuals. The negative impact of chronic rhinosinusitis and nasal polyps on patients' QOL includes physical functioning, role physical, bodily pain, mental health, vitality, general health, and emotional consequences. The problems of nasal discharge, sleep, and dizziness should be sufficiently emphasized in clinical treatment.

OBJECTIVEThe purpose of this article is to establish an endoscopic score system for quantitative evaluation of the inflammation of mucous membrane in patients with chronic rhinosinusitis (CRS) , and to investigate the correlation of this system with a variety of clinical factors.

METHODSA set of score system was constructed based on anatomic configuration, status of mucous membrane and nasal secretion to evaluate quantificationally the severity of inflammation of CRS. The clinical correlation of this system was studied prospectively in 60 CRS patients, with a variety of clinical factors which included age, duration of disease, previous recurrence and the years from recent recurrence, atopy, serum total immunoglobulin E (TIgE), serum eosinophil cationic protein (ECP), the count of blood eosinophil, the count of tissue inflammatory cell, the extension of CRS indicated by CT, smoking, concomitant chronic inflammation in lower respiratory tract. All above factors were analyzed statistically with the endoscopic score by Pearson correlation and multi-factor linear regression analysis.

RESULTSIn pearson analysis, the correlative factors with the evaluated score included age (x1, r = - 0.310, P = 0.016), the extension of disease (x2, r = 0. 810, P < 0.0005), recurrence (x3, r = 0.408, P = 0.001), eosinophil of nasal tissue (x4, r = 0.279, P = 0. 031), duration of disease (x5, r = 0.536, P < 0.0005), concurrent nasal polyps (r = 0.549, P < 0.0005), plasm cell (r = 0. 317, P = 0.014) and years from the recent recurrence (r = 0.385, P = 0.002). In multi-factor linear regression, the five independent predictive factors were recurrence, age, extension of disease, tissue eosinophils, years of disease. The regressive equation is y = 10.148 - 0.152 (x1) + 2.250 (x2) + 3.348 (x3) + 1.233 (x4) + 0.270 (x5).

CONCLUSIONSAppropriate score system by nasal endoscopy is feasible to evaluate quantificationally the degree of inflammation of CRS; being appropriately modified, it is even able to reveal the underlying histological behavior finely.
