Objective To analyze the effect of nasopharyngeal ventilation on the detection rate of colorectal polyps in 200 middle-aged and elderly overweight patients during painless colonoscopy. Methods A total of 100 patients aged 50-75 years, body mass index (BMI) ≥24 or abdominal circumference ≥85 cm in males and ≥82 cm in females, without underlying diseases, who underwent nasopharyngeal ventilation during painless colonoscopy at physical examinations in our hospital from 2019 to 2020, were selected as the observation subjects (n = 100). The control sample area was determined by propensity matching according to the basic information characteristics presented by the observation group. 100 patients received mask oxygen at physical examinations were randomly selected in the control group (n = 100). Results The verification analysis after matching indicated that there were no intraoperative and postoperative adverse reactions, the number of intraoperative limb movements was less than 1, and the intestinal peristalsis intervals were more than 5s in both groups, without atropine intervention. Colonoscopy was performed by senior endoscopists with a withdrawal time of 6-8 min. When the intraoperative SpO2 was lower than 90% but higher than 85%, the patients in the observation group underwent nasopharyngeal ventilation while those in the control group received mask oxygen assisted chin-lift. As a result, the SpO2 was maintained higher than 90%. The detection rate of colorectal polyps was compared between the two groups. Conclusion The detection rate of colorectal polyps in the observation group was higher than that in the control group, with a statistically significant difference. It may result from the reduction of ineffective respiratory movement and intraoperative intestinal peristalsis in middle-aged and elderly overweight patients.

Abstract: Introduction and aim: The aim was to assess the incidence of endoscopic findings based on the indication of the procedures in upper/lower endoscopies, and measuring quality indicators of colonoscopies at the 1st Department of Medicine, Semmelweis University, Budapest. Method: Data of 2987 patients (male/female:1361/1626, mean age: 60.7 years(y), SD: 16.7y) between 01.01.2010 and 31.12.2011 were analyzed. Both inpatient and outpatient records were collected. Results: Incidence of peptic ulcer disease, esophageal varices, gastric polyps and gastric cancer were 10.8%, 4.5%, 6.1%, 2.9% in upper endoscopies, respectively. In colonoscopies colorectal polyps, diverticulosis, colorectal cancer and IBD were found in 29.9%, 22.4%, 6.9%, 9.7%, respectively. In patients having upper endoscopy with GI bleeding indication, older age (p<0.001), male gender (p<0.001, OR: 1.64), acenocoumarol/heparin use (p<0,001, peptic ulcers and esophageal varices were more frequent (p<0.001, OR: 2.83 and p<0.001, OR: 2.79), while in colonoscopies colorectal cancer had higher incidence (p<0.001, OR:3.27). 81% of colonoscopies were complete. Causes of incomplete procedures were ineffective bowel preparation (38.2%), technical difficulties (25.1%) and strictures (20.5%). Conclusion: The endoscopic findings and quality indicators (adenoma detection rate, coecal intubation rate) were in line with that reported in published series. Orv.

AbstractColonoscopy is the gold standard for colorectal cancer (CRC) prevention. The main quality indicator of colonoscopy is the adenoma detection rate, which is inversely associated with the risk of interval CRC and the risk of death from this neoplasia. In the setting of CRC prevention, diagnostic colonoscopy has undergone a remarkable evolution in the past 20 years. Hand in hand with the implementation of CRC prevention programs and technological advances, we are now able to identify tiny and subtle neoplastic lesions and predict their histology with great efficiency. In this article, we briefly review the endoscopy technologies that can be used to improve the detection and characterization of colorectal polyps.

BACKGROUND /AIMS: Colorectal cancer is the third most common cancer in 2018, the objective of our study was to describe the types and patterns of colorectal polyps in patients presenting to a tertiary care referral center in Baghdad. We also assessed the polyp detection rate (PDR) and adenoma detection rate (ADR). PATIENTS &amp; METHODS: This is single-institution, descriptive cross-sectional study of consenting 103 patients who had colonoscopy done at the Endoscopy Unit of Baghdad teaching hospital, IRAQ from the 1st of June 2018 to 31st of March 2019 after taking verbal consent, The data collected included: Age, sex, Family history of colorectal malignancies and indication for the current colonoscopy. RESULTS: One thousand and thirty patients were included in the study with a mean age of 44 years (SD = 16), with 560 males representing 54.4% and 470 females representing 45.66%.The polyp detection rate in colonoscopies was 19.4% and the adenoma detection rate was 13.6%. Polyps were found and removed in 200 patients, 40% of the removed polyps were tubular adenomas, tubulovillous adenomas in 20%, villous adenomas in 10%, hyperplastic polyps in 5%. The majority of the polyps were in the distal colon in 80% of patients with polyps. CONCLUSIONS: The polyp detection rate was (19.4%) and adenoma detection rate was (13.6%). The majority of polyps were detected in distal colon.

Background: Colonoscopy is the gold standard for adenoma detection. All endoscopists who perform colonoscopy must by mandate be skilled to perform polypectomy. However, there are significant differences between endoscopists in terms of the polyp detection rate and in the effectiveness of polypectomy. Summary: Most polyps identified can be managed by conventional polypectomy and do not pose a significant challenge for resection to an adequately skilled and trained endoscopist. Up to 15% of polyps may be considered “difficult”, unsuitable for conventional endoscopic removal because of size, morphology, site, or access grade. Endoscopist-, patient- and polyp-specific viewpoints influence the management of difficult polyps. Advances in endoscopic resection techniques have led to extended indications for polypectomy. Conventional endoscopic removal of colorectal polyps is associated with a small but not negligible incidence of complications, most commonly bleeding and perforation. Advanced techniques for difficult polyps can potentially cause significant, even life-threatening complications. In addition, in the presence of “difficult” polyps, complications are more common. Key Messages: Multiple techniques are now available for the resection of difficult polyps. The endoscopist should individualize the appropriate approach for the treatment of difficult polyp in order to maximize oncological safety, efficacy and minimize complications and unnecessary surgery.

Abstract Background: To evaluate the effect of using linaclotide as an adjunctive agent with 3L polyethylene glycol (PEG) for bowel preparation among patients with Bristol stool form (BSFS) 1-2. Methods: Patients with BSFS 1-2 randomly received either 3L PEG (group A) or linaclotide plus 3L PEG (group B), patients with BSFS 3-7 received 3L PEG (group C) for bowel preparation. The primary outcome was the rate of adequate bowel preparation. The secondary endpoints were the polyp detection rate (PDR), acceptability and tolerability. Results: A total of 315 patients who underwent colonoscopy were enrolled. In per-protocol analysis, patient in group B attained significantly satisfactory bowel preparation rate than group A (77.9% vs 61.8%, PAB=0.049). The PDR in group B was significantly higher than group A (32.7% vs 15.7%, PAB=0.004), especially in rectosigmoid (25.0% vs 8.8%, PAB=0.002). Conclusion: 3L PEG plus 290ug Linaclotide can significantly improve the quality of bowel preparation and the colorectal polyps detection rate in patients with BSFS 1-2. The bowel preparation regimens is an effective and well-tolerated bowel preparation regimen.Trial registration: The study was registered at Chinese ClinicalTrials.gov (ChiCTR2100050437, 27/8/2021)
