Background: Current strategies to prevent colorectal cancer (CRC) vary considerably regarding safety, invasiveness, and patient satisfaction. A known deterrent for patients is the required bowel cleansing for colonoscopy. A new colon-scan capsule system is a unique preparation-free approach that provides structural information on colonic mucosa intended for detection of colorectal polyps and masses., Aims: The aim of this study was to determine safety and patient satisfaction with the colon-scan capsule., Methods: Prospective single-arm pilot study conducted at two tertiary care centers. Patients with a pre-scheduled colonoscopy for CRC screening or surveillance were included. Patients participating in this study underwent the colon-scan capsule and colonoscopy. Safety was defined by the occurrence of procedure or device-related adverse events. Satisfaction was based on survey questionnaires using a scoring system 1 (strongly disagree) to 5 (strongly agree). Patient satisfaction with the colon-scan capsule was compared to colonoscopy., Results: Forty patients were included (52.9 [5.7] years; 64.1% females). There were no serious adverse events and no occurrences of capsule retention. The most common (12.5%) complaint was self-limiting abdominal cramping. Satisfaction questionnaires were completed by more than 87% of patients, with patients likely to recommend the capsule (score 4.1 [1.03]) compared to colonoscopy (score 2.8 [1.2]), p = 0.001., Conclusions: The new prepless colon-scan capsule system is an innovative, minimally invasive technology with demonstrated safety and high patient satisfaction. A multicenter pivotal study is planned to validate the performance, safety, and accuracy of polyp detection using the capsule system in comparison with colonoscopy., (© 2021.

Goal: The purpose of this study was to assess the effect of decreased colonoscopy reimbursement on gastroenterologist practice behavior, including time to retirement and procedure volume., Background: In 2015, the Centers for Medicare and Medicaid Services proposed reductions in colonoscopy reimbursements. With new initiatives for increased colorectal cancer screening, it is crucial to understand how reimbursement changes could affect these efforts., Study: Randomly selected respondents from the American College of Gastroenterology membership database were surveyed on incremental changes in practice behavior if colonoscopy reimbursement were to decrease by 10, 20, 30, or 40 %. Data were analyzed using both Pearson's Chi-square and analysis of variance., Results: Two thousand and nine gastroenterologists received the survey with a 16.3 % response rate. Procedure volume significantly decreased with degree of reimbursement reductions (p < 0.001). With a 10 % decrease, 72 % of respondents reported no change in the number of colonoscopies performed. With a 20 % decrease, 39 % would decrease their procedure volume, while 21 % of respondents would increase their procedure volume. With a 30 and 40 % decrease, procedure volume decreased by 48 and 50 %, respectively. In terms of retirement, current plans predict a cumulative retirement rate of 29.4 % at 10 years. More than 42 % of respondents plan to retire after 2030. In the 2014-2023 retirement subgroup (N = 74 responses), there was a significant hastening of retirement year at 20 % (p = 0.016), 30 % (p < 0.001), and 40 % (p < 0.001) reimbursement reductions as compared to baseline responses., Conclusion: Decreasing colonoscopy reimbursements may have a significant effect on the effective gastroenterology work force.

Background: Lymph nodes (LNs) echofeatures on endoscopic ultrasound (EUS) and concurrent fine needle aspiration (FNA) are alternatives to highly invasive approaches for etiologic diagnosis of mediastinal lymphadenopathy (MLAD)., Aims: To evaluate the efficacy of LNs echofeatures and FNA via EUS to distinguish benign LNs from LNs involved by sarcoidosis, lymphoma, and metastasis in non-lung cancer patients., Methods: A retrospective review of patients who underwent EUS-FNA for MLAD was performed. Echofeatures of LNs including echogenicity, margins, shape, and LN size were recorded. Final diagnosis was made based on surgical sampling or clinical diagnosis with long-term follow-up. Only patients diagnosed as benign MLAD, sarcoidosis, lymphoma, and metastasis included. Diagnostic value of echofeatures and FNA was evaluated., Results: Included were 162 patients with final diagnosis of benign (68), sarcoidosis (33), lymphoma (20), and metastasis (41). The median LN along axis in the benign group [20.5 mm (6-76)] was significantly shorter than in the metastasis [28 mm (9-82)] and sarcoidosis [27 mm (17-50)] groups (p < 0.05). The median LN short axis in the benign group [11 mm (2-50)] was significantly shorter than in the metastasis [17 mm (5-44)] and lymphoma [16 mm (7-47)] groups (p < 0.05). No other echofeatures showed a discriminant value among the groups. When performing FNA, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA were 73.7, 100, 100, 72.2, and 84.4 %, respectively., Conclusion: Although benign MLAD tend to be smaller than other etiologies, echofeatures of LNs are not reliable etiologic diagnostic approach to MLAD. Therefore, FNA is suggested when feasible. However, due to relatively low sensitivity, LNs with benign FNA results should be subjected to further work-up if they are clinically suspicious.
