The Impact

Abstract Background and study aims Colorectal cancer (CRC) screening with biennial fecal occult blood test has been shown to reduce CRC mortality. For the effectiveness of the CRC screening program is crucial that a high-quality colonoscopy with a high adenoma detection rate (ADR) be performed. To improve ADR, various endoscopic devices have been developed. Endocuff, an endoscopic cap with finger-like projections, has been shown to improve ADR. The aim of this study was to compare in an organized CRC screening program ADR, advanced adenoma detection rate (AADR) and mean number of adenomas per patient (MAP) using standard colonoscopy (SC) and Endocuff-assisted colonoscopy (EAC). Patients and methods We compared performance of SC (in 2014) and EAC (in 2015) in consecutive participants in an organized CRC screening program. Results SC and EAC were performed in 546 (284 males) and 519 (293 males) subjects, respectively (mean age 60 years). Cecal intubation rate was 97.4 % for SC and 97.1 % for EAC and not significantly different (P = 0.7). ADR was 47 % for SC and 52 % for EAC, P = 0.1. MAP in SC and EAC were 0.87 (range: 0 – 7) and 1.11 (range: 0 – 13) respectively, P = 0.02. AADR rate was 25 % and 23 % for SC and EAC, respectively, P = 0.5. Conclusion Endocuff-assisted colonoscopy does not improve the number of patients with at least one adenoma but it may increase the number of detected adenomas per procedure.

Incidence And Mortality

Abstract Background Although colorectal cancer (CRC) screening programs reduce CRC incidence and mortality, they are associated with risks in healthy subjects. However, the risk of overtreatment and overdiagnosis has not been determined yet. The aim of this study was to report the surgery rates in patients with nonmalignant lesions detected within the first round of a fecal immunochemical test (FIT) based CRC screening program and the factors associated with it. Methods We included in this analysis all patients with nonmalignant lesions detected between May 2013 and June 2019 in the Galician (Spain) CRC screening program. We calculated surgery rate according to demographic variables, the risk classification according to the colonoscopy findings (European guidelines for quality assurance), the endoscopist’s adenoma detection rate (ADR) classified into quartiles and the hospital’s complexity level. We determined which variables were independently associated with surgery rate and expressed the association as Odds Ratio and its 95% confidence interval (CI). Results We included 15,707 patients in the analysis with high (19.9%), intermediate (26.9%) low risk (23.3%) adenomas and normal colonoscopy (29.9%) detected in the analyzed period. Colorectal surgery was performed in 162 patients (1.03, 95% CI 0.87–1.19), due to colonoscopy complications (0.02, 95% CI 0.00–0.05) and resection of colorectal benign lesions (1.00, 95% CI 0.85–1.16). Median hospital stay was 6 days with 17.3% patients developing minor complications, 7.4% major complications and one death. After discharge, complications developed in 18.4% patients. In benign lesions, an endoscopic resection was performed in 25.4% and a residual premalignant lesion was detected in 89.9%. The variables independently associated with surgery in the multivariable analysis were age (≥60 years = 1.57, 95% CI 1.11–2.23), sex (female = 2.10, 95% CI 1.52–2.91), the European guidelines classification (high risk = 67.94, 95% CI 24.87–185.59; intermediate risk = 5.63, 95% CI 1.89–16.80; low risk = 1.43; 95% CI 0.36–5.75), the endoscopist’s ADR (Q4 = 0.44, 95% CI 0.28–0.68; Q3 = 0.44, 95% CI 0.27–0.71; Q2 = 0.71, 95% CI 0.44–1.14) and the hospital (tertiary = 0.54, 95% CI 0.38–0.79). Conclusions In a CRC screening program, the surgery rate and the associated complications in patients with nonmalignant lesions are low, and related to age, sex, endoscopic findings, endoscopist’s ADR and the hospital’s complexity.

Abstract Background Screening sigmoidoscopy is effective in reducing mortality from colorectal cancer. In 2009, Cancer Care Ontario (CCO) launched a nurse-performed screening flexible sigmoidoscopy program at Hotel Dieu Hospital, Kingston, Ontario. Prior to this program, there was a pilot sigmoidoscopy screening program by gastroenterologists in a similar average risk cohort. Aim To compare neoplasia detection rates and associated costs of screening sigmoidoscopy performed by nurses and gastroenterologists. Method A retrospective chart review was conducted on flexible sigmoidoscopies performed as part of two average risk screening programs performed by gastroenterologists and nurse-endoscopists. Detected polyps were categorized as hyperplastic, low-risk adenomas or high-risk adenomas. Average cost per procedure was estimated based on physician fee for service charges, nurse wage and benefits, physician supervisory fees, pathology costs and administrative expenses. Results There were 538 procedures performed by nurses and 174 by physicians. Adenomas were detected in 18% of nurse-performed procedures versus 9% in physician-performed procedures (p=0.003), with the higher adenoma detection rate restricted to low risk adenomas. One cancer was found in the physician group. Seven physicians performed the 174 sigmoidoscopies, with one physician performing the majority. This physician’s adenoma detection rate was 4.5%, whereas detection rate for the remaining physicians combined was 16.5%. Nurses biopsied more polyps per case (0.96 versus 0.18). Average estimated cost per case was greater for nurses ($387.54 versus $309.37). Conclusion Well-trained nurse-endoscopists can provide an effective service for colorectal cancer screening, but as currently structured in Ontario, the associated cost is higher for nurse-performed procedures.

However, the risk of overtreatment and overdiagnosis has not been determined yet. The aim of this study is to report the surgery rates in patients with nonmalignant lesions detected within the first round of a fecal immunochemical test (FIT) based CRC screening program and the factors associated with it.

We calculated surgery rate according to demographic variables, the risk classification according to the colonoscopy findings (European guidelines for quality assurance), the endoscopist’s adenoma detection rate (ADR) classified into quartiles and the hospital’s complexity level. We determined which variables were independently associated with surgery rate and expressed the association as Odds Ratio and its 95% confidence interval (CI).Results: We included 15,707 patients in the analysis with high (19.3%), intermediate (25.1%) low risk (21.7%) adenomas and normal colonoscopy (27.8%) detected in the analyzed period. Colorectal surgery was performed in 162 (10.3‰, 95% CI 8.7-11.9), due to colonoscopy complications (0.2‰, 95% CI 0.005-0.5) and resection of colorectal benign lesions (10.0‰, 95% CI 8.5-11.6). Median hospital stay was 6 days with 17.3% patients developing minor complications, 7.4% major complications, one death. After discharge, complications developed in 18.4% patients. In benign lesions, an endoscopic resection was performed in 25.4% and a residual premalignant lesion was detected in 89.9%. The variables independently associated with surgery in the multivariable analysis were age (≥60 years= 1.57, 95% CI 1.11-2.23), sex (female= 2.10, 95% CI 1.52-2.91), the European guidelines classification (high risk= 67.94, 95% CI 24.87-185.59; intermediate risk= 5.63, 95% CI 1.89-16.80; low risk= 1.43; 95% CI 0.36-5.75), the endoscopist’s ADR (Q4= 0.44, 95% CI 0.28-0.68; Q3= 0.44, 95% CI 0.27-0.71; Q2= 0.71, 95% CI 0.44-1.14) and the hospital (third level= 0.54, 95% CI 0.38-0.79). Conclusions: In a CRC screening program, the surgery rate and the associated complications in patients with nonmalignant lesions are acceptable and related to age, sex, endoscopic findings, endoscopist’s ADR and the hospital’s complexity.
