Long-term results after EUS gallbladder drainage in high-surgical-risk patients with acute cholecystitis: A 3-year follow-up registry

Background and study aims Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has become the favorite drainage option for high surgical-risk patients with acute cholecystitis. However, data on long-term outcomes regarding efficacy and security over 1 year are scarce. Patients and methods We performed a retrospective review of a prospectively maintained database to analyze the 3-year long-term outcomes of EUS-GBD with lumen apposing metal stents (LAMS) in high-surgical-risk patients with acute cholecystitis. Results Fifty patients with acute cholecystitis who underwent EUS-GBD with LAMS and 3-year follow-up or until death were included in this study. No endoscopic revisions were scheduled unless an adverse event (AE) or suspected LAMS dysfunction occurred. AEs occurred in 18%, 20%, and 26% of patients in the first, second, and third years, respectively. Thirteen patients developed at least one AE, and six presented with a second AE during follow-up. Recurrence of cholecystitis occurred in two patients (4%). Seven stent migrations (14%) occurred but all were asymptomatic. Symptomatic LAMS-related AEs (LAMS-RAEs) (37.5%) were related to gastric location of the stent compared with duodenal location (66.7% vs. 12.5%, P = 0.03). No stent-related bleeding or stent-related mortality was observed. Conclusions EUS-GBD with LAMS without scheduled removal is an effective and safe long-term treatment in high-surgical-risk patients with acute cholecystitis. Late LAMS-RAEs tend to be more asymptomatic over time. Symptomatic LAMS-RAEs are associated with gastric location, and overall, AEs tend to recur.

Diagnostic yield of early repeat colonoscopy after suboptimal bowel preparation in a fecal immunochemical test-based screening program

BACKGROUND

Current guidelines regarding surveillance after screening colonoscopy assume adequate bowel preparation. However, follow-up intervals after suboptimal cleansing are highly heterogeneous. We aimed to determine the diagnostic yield of early repeat colonoscopy in patients with suboptimal bowel preparation in fecal immunochemical test (FIT)-based screening colonoscopy.

METHODS

An observational study including patients who underwent colonoscopy with suboptimal bowel preparation after positive FIT screening and then repeat colonoscopy within 1 year. Suboptimal preparation was defined as a Boston Bowel Preparation Scale (BBPS) score of 1 in any segment. Patients with a BBPS score of 0 in any segment or incomplete examination were excluded. The adenoma detection rate (ADR), advanced ADR (AADR), and colorectal cancer rate were calculated for the index and repeat colonoscopies.

RESULTS

Of the 2474 patients with FIT-positive colonoscopy at our center during this period, 314 (12.7 %) had suboptimal preparation. Of the 259 (82.5 %) patients who underwent repeat colonoscopy, suboptimal cleansing persisted in 22 (9 %). On repeat colonoscopy, the ADR was 38.7 % (95 %CI 32.6 % to 44.8 %) and the AADR was 14.9 % (95 %CI 10.5 % to 19.4 %). The per-adenoma miss rate was 27.7 % (95 %CI 24.0 % to 31.6 %), and the per-advanced adenoma miss rate was 17.6 % (95 %CI 13.3 % to 22.7 %). After repeat colonoscopy, the post-polypectomy surveillance recommendation changed from 10 to 3 years in 14.7 % of the patients with previous 10-year surveillance recommendation.

CONCLUSIONS

Patients with suboptimal bowel preparation on FIT-positive colonoscopy present a high rate of advanced adenomas in repeat colonoscopy, with major changes in post-polypectomy surveillance recommendations.
