Patient Navigation Plus Tailored Digital Video Disc Increases Colorectal Cancer Screening Among Low-Income and Minority Patients Who Did Not Attend a Scheduled Screening Colonoscopy: A Randomized Trial.

BACKGROUND: Up to 50% of people scheduled for screening colonoscopy do not complete this test and no studies have focused on minority and low-income populations. Interventions are needed to improve colorectal cancer (CRC) screening knowledge, reduce barriers, and provide alternative screening options. Patient navigation (PN) and tailored interventions increase CRC screening uptake, however there is limited information comparing their effectiveness or the effect of combining them. PURPOSE: Compare the effectiveness of two interventions to increase CRC screening among minority and low-income individuals who did not attend their screening colonoscopy appointment-a mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based PN compared to usual care. METHODS: Patients (n = 371) aged 45-75 years at average risk for CRC who did not attend a screening colonoscopy appointment were enrolled and were randomized to: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. CRC screening outcomes were from electronic medical records at 12 months. Multivariable logistic regression analyses were used to study intervention effects. RESULTS: Participants randomized to tailored DVD plus PN were four times more likely to complete CRC screening compared to usual care and almost two and a half times more likely than those who were sent the DVD alone. CONCLUSIONS: Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend their screening colonoscopy appointments and has potential for wide dissemination.

Up to half of people scheduled for a screening colonoscopy do not complete this test. There is a need for interventions to improve knowledge about colorectal cancer (CRC) screening, enhance access to screening by offering alternative test options, foster skills for completing screening, and mitigate barriers. The purpose of this study was to compare the effects of two interventions aimed at increasing CRC screening­a mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based patient navigation (PN)­for patients who had not completed a scheduled screening colonoscopy. We enrolled 371 patients aged 45­75 years who had no CRC risk factors other than age, who were scheduled for a screening colonoscopy but did not attend their appointment. Participants were randomized to receive either: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. Those who received the tailored DVD plus PN were four times more likely to complete CRC screening with stool test or colonoscopy compared to usual care. Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend a scheduled screening colonoscopy appointment.

Transoral incisionless fundoplication with or without hiatal hernia repair for gastroesophageal reflux disease after peroral endoscopic myotomy.

Background and study aims Gastroesophageal reflux disease (GERD) following peroral endoscopic myotomy (POEM) occurs in 40% to 60% of patients. There are limited data evaluating antireflux surgery or transoral incisionless fundoplication (TIF) for refractory post-POEM GERD. Patients and methods In a single-center prospective cohort study, consecutive patients with medically refractory post-POEM regurgitation and/or GERD treated with TIF or combined laparoscopic hernia repair and TIF (cTIF) were evaluated. Baseline evaluation: GERD-Health Related Quality of Life (GERD-HQRL) and Reflux Symptom Questionnaire 7-day recall (RESQ-7) questionnaires, EGD, high-resolution manometry (HRM), 48-hour pH test off proton pump inhibitors (PPIs) and impedance planimetry of the esophagogastric junction (EGJ) to calculate the diameter distensibility index (EGJ-DI). A PPI was taken twice daily for 2 weeks after TIF and restarted later if required. Patients returned 9 to 12 months after treatment when all preoperative studies were repeated. Quality of life, pH studies and EGJ metrics before and after antireflux surgery were compared. Results Seventeen patients underwent TIF (n=2, 12%) or cTIF (n=15, 88%) a mean 25±15 months after POEM. At follow-up a mean of 9±1 months after TIF/cTIF, patients required less frequent daily PPIs (n=0.001), were more satisfied (P=0.008), had improved GERD-HQRL (P=0.001), less intensity and frequency of GERD (P=0.001) and fewer reflux episodes (P=0.04) by pH testing. There was no change in EGJ-DI, EGJ diameter, integrated relaxation pressure, % total time pH <4, or DeMeester score. Conclusions TIF and cTIF for difficult-to-control post-POEM GERD appear safe, decrease PPI use and reflux episodes, and improve QOL without significant change in IRP, EGJ compliance, diameter or esophageal acid exposure time.

Bleeding Risk With Cold Snare Polypectomy of ≤10 mm Pedunculated Colon Polyps.

OBJECTIVES: Pedunculated polyps (PPs) in the colon are usually resected with hot snare polypectomy to prevent immediate postpolypectomy bleeding (IPPB). This study aimed to evaluate the safety of CSP of <10 mm PPs. MATERIALS AND METHODS: Patients undergoing colonoscopy from February 18, 2019, to April 24, 2020, and were found to have at least 1 ≤10 mm PP resected with CSP were included prospectively in a continuous quality improvement project to assess the risk of IPPB and delayed postpolypectomy bleeding. Polyp location, size, and pathology, as well as the method of resection, were recorded. In addition, we assessed the occurrence and severity of IPPB and the need for intervention. RESULTS: We found 239 eligible polyps in 182 patients. The mean (SD) age was 58.8 (8.3) years, and 61% were males. IPPB occurred in 72 of 239 polyps, corresponding to a per-polyp bleeding percentage of 30.1% and in 65 of 182 patients, equating to a per-patient bleeding rate of 35.7%. We successfully treated bleeding by endoscopic hemostasis in 57%; the remaining 31 polyps (43%) did not require endoscopic intervention. There was no association between IPPB with age, gender, or use of aspirin or antithrombotic agents. In the bivariate model, polyp size and pathology were not associated with the risk of IPPB. Right-sided polyps were associated with a reduced risk of IPPB in the bivariate model by 61% (odds ratio=0.39; 95% confidence interval, 0.21-0.74; P =0.0057). In the multivariate model, choking the polyp base decreased the likelihood of IPPB by 97% (odds ratio=0.03; 95% confidence interval, 0.00-0.86; P =0.0459). There were no instances of delayed bleeding, perforation, or postpolypectomy syndrome. CONCLUSIONS: CSP can be used for resection of ≤10 mm PPs. It is associated with a lower risk of immediate bleeding than the common perception among gastroenterologists.

Development of a Computer-Tailored Intervention/Decision Aid To Increase Colorectal Cancer Screening in Health Systems.

Background Non-compliance with scheduled colonoscopy is common among patients, especially in underserved populations. High no-show and late cancelation rates result in wasted resources, increased costs, and missed opportunities for colorectal cancer (CRC) screening. Among the barriers to colonoscopy is a lack of knowledge about the benefits, fears, and limited time for patient counseling. Methodology We produced a digital video disc and a website program to enhance awareness about CRC screening and address patient barriers in a population with low screening adherence. Results Patients can be educated via an interactive computer-tailored intervention with both DVD and web versions. It details the benefits and need for CRC screening, different methods of screening, and addresses patient-related barriers. Conclusions Patient education is crucial to increase CRC screening among eligible individuals. Because online engagement is affected by attention, interest, and affect, content should be concise but comprehensive.

Retrospective, observational, cross-sectional study of detection of recurrent Barrett's esophagus and dysplasia in post-ablation patients with adjunctive use of wide-area transepithelial sample (WATS-3D).

Background: Barrett's esophagus (BE) and dysplasia are often missed by Seattle protocol biopsies (SPB). Wide-area transepithelial sampling with 3-dimensional computer-assisted analysis (WATS-3D) with SPB improves detection in treatment-naïve patients. We aimed to determine to what extent WATS-3D adds to SPB in the detection of non-dysplastic BE (NDBE) and dysplasia in patients undergoing post-endoscopic eradication therapy (EET). Methods: This retrospective, observational, cross-sectional study included patients who presented for post-EET surveillance with SPB and WATS-3D sampling from April 2019 to February 2020. BE patients with no previous EET were excluded. For the outcomes of NDBE and any dysplastic/neoplastic finding, we calculated both relative and absolute increases in yield by WATS-3D over SBP. Results: In 78 patients [mean age 68±10.4 years, 66 (84.6%) male], the prevalence of NDBE, any dysplastic/neoplastic finding, and any abnormality (NDBE or dysplasia/neoplasia) were 53.85%, 10.26%, and 55.13%. The absolute increase in yield of NDBE with WATS-3D over SPB was 26.9% (95% confidence interval [CI] 17.95-37.18%), with the number needed to treat (NNT) 3.71 (95%CI 2.69-5.57) and a relative increase in yield of 100% (95%CI 53.33-188.25%). For dysplasia/neoplasia, the absolute increase in yield was 6.4% (95%CI 1.28-12.82%), NNT 15.6 (95%CI 7.8-78.0), and relative increase of 167% (95%CI 33.33%-infinity). For any abnormal finding, the absolute increase in yield was 26.9% (95%CI 16.67-37.18%), NNT 3.71 (95%CI 2.69-6.00), and relative increase in yield 95% (95%CI 50-176.92%). Conclusions: WATS-3D with SPB improves the detection of residual/recurrent BE and dysplasia in post-ablation BE. However, randomized controlled trials are needed to validate these findings.

Safety Profile of Endoscopist-directed Balanced Propofol Sedation for Procedural Sedation: An Experience at a Hospital-based Endoscopy Unit.

BACKGROUND: Nurse-administered propofol sedation was restricted to anesthesiologists in 2009, a practice that has contributed to spiraling health care costs in the United States. AIM: The aim of this study was to evaluate the safety of endoscopist-directed balanced propofol sedation (EDBPS). MATERIALS AND METHODS: We identified patients undergoing endoscopy with EDBPS from January 1, 2017, to June 20, 2017, and abstracted their medical records. Adverse events (AEs) included: hypoxia (oxygen saturation < 90%); hypotension [(a) systolic blood pressure < 90 mm Hg, (b) systolic blood pressure decline of >50 mm Hg, (c) decline in mean arterial pressure of >30%]; bradycardia (heart rate of < 40 beats/min). Logistic regression identified factors independently associated with AEs. RESULTS: A total of 1897 patients received EDBPS during the study period [mean age: 55 y (SD=11.4 y); 56.4% women]. Patients received median doses of 50 µg fentanyl, 2 mg of midazolam, and a mean propofol dose of 160±99 mg. There were no major complications (upper 95% confidence interval, 0.19%). Overall, 334 patients (17.6%) experienced a clinically insignificant AE: 65 (3.4%) experienced transient hypoxia, 277 patients (14.6%) experienced hypotension, 2 had transient bradycardia. In bivariate analysis, older age was associated with risk for hypotension, propofol dose was associated with transient hypoxemia, and procedure duration was associated with both hypotension and transient hypoxia. In multivariate analysis, only procedure length was associated with AEs (odds ratio scale 10; odds ratio=1.07; 95% confidence interval, 1.05-1.09, P<0.001). CONCLUSIONS: EDBPS is safe for endoscopic sedation. Given the higher cost of anesthesia-administered propofol, endoscopists should reinstate EDBPS by revising institutional sedation policies.

A Pilot Randomized Trial of Polypectomy Techniques for 4 to 6 mm Colonic Polyps.

BACKGROUND AND GOALS: There is variation in polypectomy techniques for resection of small polyps. Aim was to compare techniques for 4 to 6 mm polyps for recurrent adenoma, efficiency, and adverse events and to establish methodological factors for definitive trial. MATERIALS AND METHODS: The study was a randomized controlled trial. Outpatients with ≥1, 4 to 6 mm polyps were randomized to cold forceps (CF), cold snare (CS), and hot snare (HS). Polypectomy site was marked with SPOT to assess for recurrence at the original polypectomy site during surveillance colonoscopy. To assess feasibility of a definitive trial we measured (1) rates of patient refusal, participation, ineligibility; (2) retention; (3) recurrent neoplasia; and (4) sample size for a definitive trial. RESULTS: Three hundred fifty-three patients were randomized to 1 of the 3 polypectomy techniques, of whom 260 (73.6%) completed the initial colonoscopy (mean age 57 y, 50.4% women), with 91, 87, and 82 patients randomized to CF, CS, and HS polypectomy, respectively. Mean time for polyp resection for CF, CS, and HS were 198.8, 58.5, and 96.8 seconds, respectively, with CS and HS requiring less time than CF (P<0.001). One hundred sixty-four (63.1%) completed surveillance colonoscopy. Polyp recurrences were 9 (14.5%) with CF, 5 (9.6%) with CS, and 0 (0%) with HS. Although the recurrence relative risks with CF and CS polypectomy were 1.84 and 1.65 as compared with HS, respectively, neither was statistically significant. CONCLUSIONS: CS and HS polypectomy require less time than CF. HS polypectomy may have a lower risk for recurrent neoplasia. High attrition rate is a challenge in conducting randomized controlled trial with polyp recurrence as endpoint.

Process Evaluation of a Mailed Interactive Educational DVD in a Comparative Effectiveness Trial to Promote Colorectal Cancer Screening.

A process evaluation was conducted as part of a comparative effectiveness trial of a mailed interactive educational DVD intervention to promote colorectal cancer screening among average-risk patients who did not attend a scheduled colonoscopy. Participants (n = 371) for the trial were randomized to (1) mailed DVD, (2) mailed DVD plus patient navigation, or (3) usual care. Participants (n = 243) randomized to the two DVD intervention arms were called 2 weeks after mailing materials to complete a process evaluation interview about the DVD (September 2017-February 2020). Forty-nine (20%) participants were not reached, and 194 (80%) participants watched the DVD and completed the interview. The process evaluation assessed whether (1) the DVD content was helpful, (2) any new information was learned by participants, (3) the appropriate amount of information was included in the DVD, (4) participants were engaged when watching the DVD, (5) the DVD content was relevant, (6) participants were satisfied with the DVD (7) participants would recommend the DVD to others, and (8) their opinion about colorectal cancer screening was changed by watching the DVD. Among participants who watched the DVD, 99% reported the screening information was very or somewhat helpful, 47% learned new information, 75% said the DVD included the right amount of information, they were engaged (M = 3.35 out of 4, SD = 0.49), 87% reported all or most information applied to them, they were satisfied (M = 3.42 out of 4, SD = 0.39) with DVD content, 99% would recommend the DVD to others, and 45% reported changing their opinion about screening. To understand the effects of interventions being tested in trials and to plan the dissemination of evidence-based interventions, process evaluation is critical to assess the dose received and acceptability of behavioral interventions.

Systematic review with meta-analysis: neoplasia detection rate and post-endoscopy Barrett's neoplasia in Barrett's oesophagus.

BACKGROUND: Neoplasia detection rate, the proportion of Barrett's oesophagus patients with high-grade dysplasia or oesophageal adenocarcinoma detected at index surveillance endoscopy has been proposed as a quality metric. However, the correlation between neoplasia detection rate and a clinically relevant outcome like post-endoscopy Barrett's neoplasia remains unknown. Post-endoscopy Barrett's neoplasia refers to the rate of high-grade dysplasia or oesophageal adenocarcinoma on repeat endoscopy within one year of an index screening examination revealing non-dysplastic Barrett's oesophagus or low-grade dysplasia. AIM: To assess correlation between neoplasia detection rate and post-endoscopy Barrett's neoplasia. METHODS: We performed a systematic search of multiple databases from date of inception to June 2021 to identify cohort studies reporting both neoplasia detection rate and post-endoscopy Barrett's neoplasia. Data from each study were pooled using a random effects model, and their correlation assessed using meta-regression. Heterogeneity was assessed and a priori planned subgroup analyses were conducted. RESULTS: Ten studies with 27 894 patients with Barrett's oesophagus were included. The pooled neoplasia detection rate and post-endoscopy Barrett's neoplasia were 5.0% (95% CI: 3.4%-7.1%, I2  = 97%) and 19.6% (95% CI: 10.1%-34.7%, I2  = 96%), respectively. Meta-regression revealed a statistically significant inverse relationship between the two variables (coefficient -3.50, 95% CI: -4.63 to -2.37, P < 0.01). With every 1% increase of neoplasia detection rate, post-endoscopy Barrett's neoplasia decreased by 3.50%. Heterogeneity was high despite adjusting for study quality and performing several subgroup analyses. CONCLUSION: We observed a statistically significant inverse correlation between neoplasia detection rate and post-endoscopy Barrett's neoplasia. Additional studies are needed to further validate this correlation.

Delayed Removal of Entrapped Snare in Colonoscopic Polypectomy.

Snare entrapment is a rare complication of hot snare polypectomy of large colon polyps. We report a case of snare entrapment in our unit and its management. This report highlights the method of delayed removal of snare followed by repeat colonoscopy.

Metal Stent Insertion for Malignant Obstruction of a Colostomy.

A 47-year-old female with metastatic cervical cancer and diverting colostomy presented with abdominal distention and minimal stool output from her colostomy. A computed tomography (CT) scan revealed a metastatic mass causing partial obstruction at the colostomy level and significant proximal colonic dilation. Her obstruction was relieved by the endoscopic placement of a metal stent through the stoma, with the stent's distal edge visible externally but not protruding beyond skin level. Two months later, the stent remained patent and did not migrate. This case highlights a viable palliative treatment option for patients who are not operative candidates.

A Case Report of an Early Response to Definitive Chemoradiation for Esophageal Carcinoma Cuniculatum.

This case report describes a 63-year-old female with a locally advanced esophageal carcinoma cuniculatum treated with definitive chemoradiation who had a rapid and early response. This case is illustrative of an aggressive behavior with rapid response and rapid recurrence. The cases of esophageal carcinoma cuniculatum as well as the closely related clinical entity of verrucous carcinoma are reviewed suggesting good clinical outcomes after definitive therapy with chemoradiation and/or surgery.

Impact of the development of an endoscopic eradication program for Barrett's esophagus with high grade dysplasia or early adenocarcinoma on the frequency of surgery.

Background and aims The impact of the advent of an institutional endoscopic eradication therapy (EET) program on surgical practice for Barrett's esophagus (BE)-associated high grade dysplasia (HGD) or suspected T1a esophageal adenocarcinoma (EAC) is unknown. The aims of this study are to evaluate the different endoscopic modalities used during development of our EET program and factors associated with the use of EET or surgery for these patients after its development. Methods Patients who underwent primary endoscopic or surgical treatment for BE-HGD or early EAC at our hospital between January 1992 and December 2014 were retrospectively identified. They were categorized by their initial modality of treatment during the first year, and the impact over time for choice of therapy was assessed by multivariable logistic regression. Results We identified 386 patients and 80 patients who underwent EET and surgery, respectively. EET included single modality therapy in 254 (66 %) patients and multimodal therapy in 132 (34 %) patients. Multivariable logistic regression showed that, for each subsequent study year, EET was more likely to be performed in patients who were older ( P  = 0.0009), with shorter BE lengths ( P  < 0.0001), and with a pretreatment diagnosis of HGD ( P  = 0.0054) compared to surgical patients. The diagnosis of EAC did not increase the utilization of EET compared to surgery as time progressed ( P  = 0.8165). Conclusion The introduction of an EET program at our hospital increased the odds of utilizing EET versus surgery over time for initial treatment of patients who were older, had shorter BE lengths or the diagnosis of BE-HGD, but not in patients with EAC.

Autoimmune Ascites Responding to Mycophenolate Mofetil: A Case Report.

Ascites is an abnormal accumulation of fluid within the peritoneal cavity. The most common cause of ascites in the United States population is portal hypertension secondary to cirrhosis, accounting for about 80% of the cases. Other etiologies include malignancy, heart failure, tuberculosis, and pancreatic disease. After an extensive literature review, it is to our best knowledge that there have been no cases reported on autoimmune ascites. We present an interesting case of ascites in a 67-year-old Caucasian male with symptoms of recurrent abdominal distention and significant weight gain, refractory to standard therapies. An extensive 3-year long workup was only significant for serum-ascites albumin gradient > 1.1 g/dL, ascitic fluid protein of 3.0 g/dL, and peritoneal biopsies showing minor inflammatory changes. Both common and rare causes of ascites were ruled out. Empiric treatment with mycophenolate mofetil (CellCept) resulted in resolution of symptoms with no need for a repeat paracentesis for > 2 years, suggesting the diagnosis of autoimmune ascites.

Outcomes of submucosal (T1b) esophageal adenocarcinomas removed by endoscopic mucosal resection.

AIM: To investigate the outcomes and recurrences of pT1b esophageal adenocarcinoma (EAC) following endoscopic mucosal resection (EMR) and associated treatments. METHODS: Patients undergoing EMR with pathologically confirmed T1b EAC at two academic referral centers were retrospectively identified. Patients were divided into 4 groups based on treatment following EMR: Endoscopic therapy alone (group A), endoscopic therapy with either chemotherapy, radiation or both (group B), surgical resection (group C) or no further treatment/lost to follow-up (< 12 mo) (group D). Pathology specimens were reviewed by a central pathologist. Follow-up data was obtained from the academic centers, primary care physicians and/or referring physicians. Univariate analysis was performed to identify factors predicting recurrence of EAC. RESULTS: Fifty-three patients with T1b EAC underwent EMR, of which 32 (60%) had adequate follow-up ≥ 12 mo (median 34 mo, range 12-103). There were 16 patients in group A, 9 in group B, 7 in group C and 21 in group D. Median follow-up in groups A to C was 34 mo (range 12-103). Recurrent EAC developed overall in 9 patients (28%) including 6 (38%) in group A (median: 21 mo, range: 6-73), 1 (11%) in group B (median: 30 mo, range: 30-30) and 2 (29%) in group C (median 21 mo, range: 7-35. Six of 9 recurrences were local; of the 6 recurrences, 5 were treated with endoscopy alone. No predictors of recurrence of EAC were identified. CONCLUSION: Endoscopic therapy of T1b EAC may be a reasonable strategy for a subset of patients including those either refusing or medically unfit for esophagectomy.

Narrow-band imaging versus white light for the detection of proximal colon serrated lesions: a randomized, controlled trial.

BACKGROUND: The value of narrow-band imaging (NBI) for detecting serrated lesions is unknown. OBJECTIVE: To assess NBI for the detection of proximal colon serrated lesions. DESIGN: Randomized, controlled trial. SETTING: Two academic hospital outpatient units. PATIENTS: Eight hundred outpatients 50 years of age and older with intact colons undergoing routine screening, surveillance, or diagnostic examinations. INTERVENTIONS: Randomization to colon inspection in NBI versus white-light colonoscopy. MAIN OUTCOME MEASUREMENTS: The number of serrated lesions (sessile serrated polyps plus hyperplastic polyps) proximal to the sigmoid colon. RESULTS: The mean inspection times for the whole colon and proximal colon were the same for the NBI and white-light groups. There were 204 proximal colon lesions in the NBI group and 158 in the white light group (P = .085). Detection of conventional adenomas was comparable in the 2 groups. LIMITATIONS: Lack of blinding, endoscopic estimation of polyp location. CONCLUSION: NBI may increase the detection of proximal colon serrated lesions, but the result in this trial did not reach significance. Additional study of this issue is warranted. ( CLINICAL TRIAL REGISTRATION NUMBER: NCT01572428.).
