Endoscopy-Related Bleeding and Thromboembolic Events in Patients on Direct Oral Anticoagulants or Vitamin K Antagonists.

BACKGROUND & AIMS: Few prospective studies have assessed the safety of direct oral anticoagulants (DOACs) in elective endoscopy. Our primary aim was to compare the risks of endoscopy-related gastrointestinal bleeding and thromboembolic events in patients on DOACs or vitamin K antagonists (VKAs) in this setting. Secondarily, we examined the impact of the timing of anticoagulant resumption on the risk of delayed bleeding in high-risk therapeutic procedures. METHODS: We conducted a multicenter, prospective, observational study from January 2018 to March 2020 of 1602 patients on oral anticoagulants (1004 on VKAs and 598 on DOACs) undergoing 1874 elective endoscopic procedures. Our primary outcomes were 90-day thromboembolic events and 30-day endoscopy-related gastrointestinal bleeding. The inverse probability of treatment weighting propensity score method was used for baseline covariate adjustment. RESULTS: The 2 groups had similar risks of endoscopy-related gastrointestinal bleeding (VKAs vs DOACs, 6.2% vs 6.7%; adjusted odds ratio [OR], 1.05; 95% CI, 0.67-1.65) and thromboembolic events (VKAs vs DOACs, 1.3% vs 1.5%; adjusted OR, 0.90; 95% CI, 0.34-2.38). In high bleeding risk procedures (n = 747), delayed anticoagulant resumption (> 48 hours or 24-48 hours vs < 24 hours) did not reduce the risk of postprocedural bleeding (10.3%, 9%, and 5.8%, respectively; adjusted P = .43). Hot and cold snare polypectomy were the most frequent high-risk interventions (41.8% and 39.8%, respectively). CONCLUSION: In a prospective study of patients on DOACs or VKAs undergoing elective endoscopy, endoscopy-related bleeding and thromboembolic events showed similar risk. Our study suggests that early anticoagulant resumption is safe in most patients, but more data are needed for advanced high-risk therapeutic procedures.

Evaluation of long-term adherence to oesophagogastroduodenoscopy quality indicators. / Evaluación del cumplimiento a largo plazo de los indicadores de calidad en la esofagogastroduodenoscopia.

INTRODUCTION: In a previous study we demonstrated that a simple training programme improved quality indicators of Oesophagogastroduodenoscopy (OGD) achieving the recommended benchmarks. However, the long-term effect of this intervention is unknown. The aim of this study was to assess the quality of OGDs performed 3 years after of having completed a training programme. MATERIAL AND METHODS: A comparative study of 2 cohorts was designed as follows: Group A included OGDs performed in 2016 promptly after a training programme and Group B with OGDs performed from January to March 2019, this group was also divided into 2 subgroups: subgroup B1 of Endoscopists who had participated in the previous training programme and subgroup B2 of Endoscopists who had not. The intra-procedure quality indicators proposed by ASGE-ACG were used. RESULTS: A total of 1236 OGDs were analysed, 600 from Group A and 636 from Group B (439 subgroup B1 and 197 subgroup B2). The number of complete examinations was lower in Group B (566 [94.3%] vs. 551 [86.6%]; p<0.001). A significant decrease was observed in nearly all quality indicators and they did not reach the recommended benchmarks: retroflexion in the stomach (96% vs. 81%; p<0.001); Seattle biopsy protocol (86% vs. 50%; p=0.03), description of the upper GI bleeding lesion (100% vs. 62%; p<0.01), sufficient intestinal biopsy specimens (at least 4) in suspected coeliac disease (92.5% vs. 18%; p<0.001), photo documentation of the lesion (94% vs. 90%; p<0.05). Regarding the overall assessment of the procedure (including correct performance and adequate photo documentation), a significant decrease was also observed (90.5% vs. 62%; p<0.001). There were no differences between subgroups B1 and B2. CONCLUSIONS: The improvement observed in 2016 after a training programme did not prevail after 3 years. In order to keep the quality of OGDs above the recommended benchmarks, it is necessary to implement continuous training programmes.

Quality indicators for esophagogastroduodenoscopy: A comparative study of outcomes after an improvement programme in a tertiary hospital. / Indicadores de calidad en la esofagogastroduodenoscopia: estudio comparativo de los resultados tras un programa de mejora en un hospital terciario.

INTRODUCTION: There is an opportunity for improvement in the recording and measuring of quality indicators. However, no previous experiences exist in our field in terms of their compliance in esophagogastroduodenoscopy (EGD). OBJECTIVE: To analyse compliance with EGD quality criteria and evaluate improvement after conducting a training programme. PATIENTS AND METHODS: Comparative study of 2 cohorts: one retrospective (control group) and one prospective (intervention group), before and after a training programme consisting of an information session and the report writing improvement programme. The quality indicators proposed by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology were used. RESULTS: A total of 1,200 EGDs were included in a sequential manner (600 in each group). Following the training programme, a significant improvement was observed in the following indicators: documented indication (93 vs. 99.8%; P<0.01), documented full examinations (94.7 vs. 97.3%; P<0.01), correct performance (63.7 vs. 87.9%; P<0.01), appropriate biopsies according to protocols (57.9 vs. 83.8%; P<0.01), photo-documentation of described lesions (84.1 vs. 94.9%; P<0.01), photo-documentation per segment (52.9 vs. 70.5%; P<0.01) and correct overall assessment (56,9 vs. 90.5%; P<0.01). Biopsies for coeliac disease, documented indication, full examination and correct performance, if it went ahead, exceeded the recommended standard. CONCLUSION: A very simple training programme improves EGD quality indicators, with the majority reaching the standards recommended by the American Society for Gastrointestinal Endoscopy and the American College of Gastroenterology.

Curative criteria for endoscopic treatment of gastric cancer.

Endoscopic treatment, particularly endoscopic submucosal dissection, has become the primary treatment for early gastric cancer. A comprehensive optical assessment, including white light endoscopy, image-enhanced endoscopy, and magnification, are the cornerstones for clinical staging and determining the resectability of lesions. This paper discusses factors that influence the indication for endoscopic resection and the likelihood of achieving a curative resection. Our review stresses the critical need for interpreting the histopathological report in accordance with clinical guidelines and the imperative of tailoring decisions based on the patients' and lesions' characteristics and preferences. Moreover, we offer guidance on managing complex scenarios, such as those involving non-curative resection. Finally, we identify future research avenues, including the role of artificial intelligence in estimating the depth of invasion and the urgent need to refine predictive scores for lymph node metastasis and metachronous lesions.

Adherence to patient blood management strategy in patients with gastrointestinal bleeding: a prospective nationwide multicenter study.

INTRODUCTION: Patient blood management (PBM) adherence in clinical practice is unclear. This real-world practice study assessed the management of patients with gastrointestinal (GI) bleeding after the implementation of the PBM strategy. METHODS: This was a nationwide multicenter and prospective study involving consecutive adults with GI bleeding between March 2019 and March 2021. Patients were examined according to hemoglobin (Hb) level at admission (<7 g/dl, n = 93; 7-8 g/dl, n = 47; 8-9 g/dl, n = 61; and >9 g/dl, n = 249). Study outcomes measures were morbidity and mortality during hospitalization and at 3- and 6-month follow-up. Appropriate anemia or iron deficiency management was considered when adherence to PBM policy was higher than 75%. RESULTS: A total of 450 patients (57.6% men, median age: 74 years, interquartile range: 63-82) were included. Overall, 55.1% and 59.3% of patients received transfusion and iron supplementation, respectively. The rates of appropriate transfusion and iron supplementation adherence were 90.9% (range: 86.9-93.5%, P = 0.109) and 81.8% (range: 78.5-85.1%, P = 0.041), depending on Hb level, respectively. No associations were observed between adherence to the PBM strategy and length of stay (P = 0.263) or risk of further bleeding (P = 0.742). Patients who were transfused [hazard ratio (HR): 0.79, 95% confidence interval (CI): 0.27-0.85] and iron supplemented (HR: 0.91, 95% CI: 0.38-1.41), however, appropriately achieved a lower risk of death. Age (HR: 1.12, 95% CI: 1.12-1.25) and further bleeding (HR: 39.08, 95% CI: 4.01-181.24) were poor prognostic factors. No serious adverse events were reported. CONCLUSIONS: In this nationwide study, there is a high level of adherence and safety of PBM for the treatment of GI bleeding. Adherence to the PBM strategy improved outcomes in patients with GI bleeding.
