Prospective evaluation of the effectiveness of colonoscopic polyp resection
International Journal of Family & Community Medicine
Background: Colon cancer incidence is on the rise and despite having undergone a colonoscopy to screen and remove all visible polyps as a preventive measure, nearly 1 in 110 patients will develop colon cancer within 3 years. The three main possible explanations for this are missing polyps, incompletely removed polyps, or rapidly growing tumors. Objective: To determine the proportion of colonic polyps ≤ 3 cm in size that show evidence of residual polyp tissue following colonoscopy and polypectomy. Methods: Patients who presented for colonoscopy at a community center were invited to participate in this study. Those who had confirmed adenoma were invited to repeat the procedure in 2 to 6 months with biopsies at the resection site to check for the presence of residual polyp tissue. Exclusion criteria included the absence of adenoma in the resected lesion, contraindication to polypectomy or follow-up colonoscopy, refusal to participate in follow-up examination, and other conditions incre...
Importance of Early Follow-up Colonoscopy in Patients at High Risk for Colorectal Polyps
Annals of coloproctology, 2013
Minimizing the polyp miss rate during colonoscopy is important for patients at high risk for colorectal polyps. We investigated the polyp miss rate and the factors associated with it in high-risk patients. The medical records of 163 patients who underwent follow-up colonoscopy between January 2001 and April 2010, which was within 9 months after a polypectomy, because the index colonoscopy had shown multiple (more than 3) adenomas or advanced adenoma were retrospectively reviewed. Miss rates were calculated for all polyps, for neoplastic polyps and for advanced adenomas. Factors associated with the miss rates in these patients, such as the location, shape and size of the polyp, were analyzed. The miss rates for polyps, adenomas, adenomas <5 mm, adenomas ≥5 mm and advanced adenomas were 32.6%, 20.9%, 17.7%, 3.2%, and 0.9%, respectively. No carcinoma, except for one small carcinoid tumor, was missed. Flat shape and small size (<5 mm) were significantly associated with adenoma mis...

BACKGROUND The incidence of colorectal cancer is increasing in the northeast of Iran. Colorectal polyps are among the proposed risk factors noted, especially in the elder population. This study was designed to study the diagnosed cases of intestinal polyps detected from 2011 to 2016 in the northeast of Iran. METHODS The population consisted of symptomatic candidates referred to the colonoscopy center in Gorgan city. Based on the available colonoscopy and pathology reports, 1706 cases were enrolled after the exclusion of cases without sufficient data. RESULTS Among 1709 (55.5% males and 44.5% females) cases, 1405 cases with 1912 polyps were detected. Among them, 345 (25%) aged less than 50 years. Tubular adenoma (N = 826, 43.2%) and hyperplastic polyps (N = 519, 27.1%) were the top two histological findings. Out of 1405 patients with polyps, 660 (39.6%) polyps were detected in proximal colon (15.6% in proximal and 24% in both proximal and distal). Malignancies were detected in 13.2% ...

Colon polypectomy decreases the incidence of colorectal cancer and related mortality. Several factors such as the size, location and type of polyp as well as endoscopist experience have been shown to correlate with the risk of ensuing procedure-related complications. This study aims to evaluate the impact of polyp and endoscopist-related factors on the rate of postpolypectomy complication in a real-life setting. During the study period all polypectomies performed in our unit were reported on a standard form that included data on polyp type (flat, sessile, pedunculated), size, location in the colon, resection method, endoscopist volume and procedure-related complications arising up to 30 days. The main outcome was the complication rate of polypectomies. The factors that associated with a higher risk of complications were assessed on univariate and multivariate analysis. 244 polyp resections from 95 patients were included in the analysis. 199 polyps were resected by low-volume endosco...

Background and Aims: Diagnostic colonoscopy allows exploration of the colonic mucosa. Indications are multiple. The purpose of this work was to describe the indications and to report the lesions observed during colonoscopy at the General Hospital of Douala. Methods: This was a cross-sectional study with retrospective data collection over a period of 7 years (January 1, 2010 to January 31, 2017). The data collected from the reports were socio-demographic characteristics, indications and lesions observed at colonoscopy. Binary logistic regression allowed us to identify the independent risk factors associated with the presence of tumors and polyps. Results: We included 719 exams. The main indications were rectorrhagia (29.5%), abdominal pain (25.9%) and constipation (17.8%). A colonic lesion was found in 60.1% of cases. A colorectal tumor accounted for 10.3% of cases. Factors independently associated with colonic tumor were complete colonoscopy (aOR: 0.167 95% CI [0.096-0.289], p < 0.001), presence of abdominal or rectal mass (aOR: 13.390 95% CI) [5.684-31.544], p < 0.001) and weight loss (aOR: 5.143, 95% CI [2.450-10.797], p < 0.001). Conclusion: The presence of weight loss, abdominal or rectal mass should motivate the realization of a complete colonoscopy in search of a colorectal tumor. The most observed lesions remain hemorrhoids, polyps and diverticulosis of the colon.
Characteristics of the Patients Undergoing Colonoscopy in a Single Center within an 8-year Period
Journal of Gastrointestinal & Digestive System, 2017
Aim: To evaluate patient characteristics by reviewing colonoscopy procedures performed within an 8-year period in the endoscopy centre of a training and research hospital. Methods: Colonoscopy procedures that were performed for various indications between 2002 and 2009 in the endoscopy unit of our hospital were retrospectively evaluated. Of 3035 colonoscopy procedures, 2831 were included in the analysis. In addition to demographic characteristics of the patients, presence and localization of colorectal masses, presence of inflammatory bowel disease, frequency of presence of hemorrhoids, diverticula, polyps, and other diseases, as well as complications were recorded. Results: The mean age of the patients (male, 50.5%) was 54.36 ± 15.05 years (range, 16-93 years). While a pathological finding was determined in 1512 (53.4%) colonoscopy procedures, 1319 (46.6%) colonoscopy procedures were reported as normal. Concerning complications during examinations, perforation was encountered in two patients and major bleeding was not determined in any of the patients. The most common diagnoses were polyps (15.9%) and hemorrhoids (15.9%), followed by colorectal mass (12.9%), diverticula (6.8%), and inflammatory bowel disease (5.6%). Conclusion: The fact that colorectal masses ranked third among the colonoscopic diagnoses suggested that cancer screening programs should be handled nationally.
