Comparison of adenoma detection in different colorectal segments between deep-sedated and unsedated colonoscopy.

ABSTRACT: To investigate if deep-sedated colonoscopy affects adenoma detection in certain colorectal segment. Review of colonoscopy reports, electronic images and medical records of individuals underwent screening colonoscopy with or without propofol sedation between October 2020 and March 2021 from seven hospitals in China. A total of 4500 individuals were analyzed. There was no significant difference in ADR between deep-sedated colonoscopy and unsedated colonoscopy [45.4% vs. 46.3%, P > 0.05]. The APP of deep-sedated colonoscopy was lower than unsedated colonoscopy (1.76 ± 0.81 vs. 2.00 ± 1.30, P < 0.05). Both average number of adenomas and luminal distention score of splenic flexure and descending colon were lower in deep-sedated colonoscopy (P < 0.05), and average number of adenomas was positively correlated with an improved distension score in splenic flexure and descending colon (splenic flexure r = 0.031, P < 0.05; descending colon r = 0.312, P < 0.05). Linear regression model showed deep-sedated colonoscopy significantly affected luminal distention of splenic flexure and descending colon as well as average number of adenomas detected in splenic flexure (P < 0.05). Deep-sedated colonoscopy decreased adenoma detection in splenic flexure and the luminal distention of splenic flexure and descending colon compared with unsedated colonoscopy.

Project description:ObjectiveThe adenoma detection rate (ADR) varies widely between physicians, possibly due to patient population differences, hampering direct ADR comparison. We developed and validated a prediction model for adenoma detection in an effort to determine if physicians' ADRs should be adjusted for patient-related factors.Materials and methodsScreening and surveillance colonoscopy data from the cross-sectional multicenter cluster-randomized Endoscopic Quality Improvement Program-3 (EQUIP-3) study (NCT02325635) was used. The dataset was split into two cohorts based on center. A prediction model for detection of ≥1 adenoma was developed using multivariable logistic regression and subsequently internally (bootstrap resampling) and geographically validated. We compared predicted to observed ADRs.ResultsThe derivation (5 centers, 35 physicians, overall-ADR: 36%) and validation (4 centers, 31 physicians, overall-ADR: 40%) cohort included respectively 9934 and 10034 patients (both cohorts: 48% male, median age 60 years). Independent predictors for detection of ≥1 adenoma were: age (optimism-corrected odds ratio (OR): 1.02; 95%-confidence interval (CI): 1.02-1.03), male sex (OR: 1.73; 95%-CI: 1.60-1.88), body mass index (OR: 1.02; 95%-CI: 1.01-1.03), American Society of Anesthesiology physical status class (OR class II vs. I: 1.29; 95%-CI: 1.17-1.43, OR class ≥III vs. I: 1.57; 95%-CI: 1.32-1.86), surveillance versus screening (OR: 1.39; 95%-CI: 1.27-1.53), and Hispanic or Latino ethnicity (OR: 1.13; 95%-CI: 1.00-1.27). The model's discriminative ability was modest (C-statistic in the derivation: 0.63 and validation cohort: 0.60). The observed ADR was considerably lower than predicted for 12/66 (18.2%) physicians and 2/9 (22.2%) centers, and considerably higher than predicted for 18/66 (27.3%) physicians and 4/9 (44.4%) centers.ConclusionThe substantial variation in ADRs could only partially be explained by patient-related factors. These data suggest that ADR variation could likely also be due to other factors, e.g. physician or technical issues.

Project description:ImportanceIndividuals with adenomatous polyps are advised to undergo repeated colonoscopy surveillance to prevent subsequent colorectal cancer (CRC), but the relationship between adenomas at colonoscopy and long-term CRC incidence is unclear.ObjectiveTo compare long-term CRC incidence by colonoscopy adenoma findings.Design, setting, and participantsMulticenter, prospective cohort study of participants in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer randomized clinical trial of flexible sigmoidoscopy (FSG) beginning in 1993 with follow-up for CRC incidence to 2013 across the United States. Participants included 154 900 men and women aged 55 to 74 years enrolled in PLCO of whom 15 935 underwent colonoscopy following their first positive FSG screening result. The final day of follow-up was December 31, 2013.ExposuresEnrolled participants had been randomized to FSG or usual care. Participants who underwent FSG and had abnormal findings were referred for follow-up. Subsequent colonoscopy findings were categorized as advanced adenoma (≥1 cm, high-grade dysplasia, or tubulovillous or villous histology), nonadvanced adenoma (<1 cm without advanced histology), or no adenoma.Main outcomes and measuresThe primary outcome was CRC incidence within 15 years of the baseline colonoscopy. The secondary outcome was CRC mortality.ResultsThere were 15 935 participants who underwent colonoscopy (men, 59.7%; white, 90.7%; median age, 64 y [IQR, 61-68]). On initial colonoscopy, 2882 participants (18.1%) had an advanced adenoma, 5068 participants (31.8%) had a nonadvanced adenoma, and 7985 participants (50.1%) had no adenoma; median follow-up for CRC incidence was 12.9 years. CRC incidence rates per 10 000 person-years of observation were 20.0 (95% CI, 15.3-24.7; n = 70) for advanced adenoma, 9.1 (95% CI, 6.7-11.5; n = 55) for nonadvanced adenoma, and 7.5 (95% CI, 5.8-9.7; n = 71) for no adenoma. Participants with advanced adenoma were significantly more likely to develop CRC compared with participants with no adenoma (rate ratio [RR], 2.7 [95% CI, 1.9-3.7]; P < .001). There was no significant difference in CRC risk between participants with nonadvanced adenoma compared with no adenoma (RR, 1.2 [95% CI, 0.8-1.7]; P = .30). Compared with participants with no adenoma, those with advanced adenoma were at significantly increased risk of CRC death (RR, 2.6 [95% CI, 1.2-5.7], P = .01), but mortality risk in participants with nonadvanced adenoma was not significantly different (RR, 1.2 [95% CI, 0.5-2.7], P = .68).Conclusions and relevanceOver a median of 13 years of follow-up, participants with an advanced adenoma at diagnostic colonoscopy prompted by a positive flexible sigmoidoscopy result were at significantly increased risk of developing colorectal cancer compared with those with no adenoma. Identification of nonadvanced adenoma may not be associated with increased colorectal cancer risk.Trial registrationclinicaltrials.gov Identifier: NCT00002540.
