Background: The quality of colonoscopy has been related to a higher risk of interval cancer, and this issue has been addressed extensively in developed countries. The aim of our study was to explore the main quality indicators of colonoscopy in a large emerging country. Methods: Consecutive patients referred for colonoscopy in 14 centres were prospectively included between July and October 2014. Before colonoscopy, several clinical and demographic variables were collected. Main quality indicators (i.e. caecal intubation rate, (advanced) adenoma detection rate, rate of adequate cleansing and sedation) were collected. Data were analysed at per patient and per centre level (only for those with at least 100 cases). Factors associated with caecal intubation rate and adenoma detection rate were explored at multivariate analysis. Results: A total of 8829 (males: 35%; mean age: 57 þ 14 years) patients were included, with 11 centres enrolling at least 100 patients. Screening (including non-alarm symptoms) accounted for 59% (5188/8829) of the indications. Sedation and split preparation were used in 26% (2294/8829) and 25% (2187/8829) of the patients. Caecal intubation was achieved in 7616 patients (86%), and it was !85% in 8/11 (73%) centres. Adenoma detection rate was 18% (1550/8829), and it was higher than 20% in five (45%) centres, whilst it was lower than 10% in four (33%) centres. At multivariate analysis, age (OR: 1.020, 95% CI: 1.015-1.024), male sex (OR: 1.2, 95% CI: 1.1-1.3), alarm symptoms (OR: 1.8, 95% CI: 1.7-2), split preparation (OR: 1.4, 95% CI: 1.2-1.6), caecal intubation rate (OR: 1.6, 95% CI: 1.3-1.9) and withdrawal time measurement (OR: 1.2, 95% CI: 1.6-2.1) were predictors of a higher adenoma detection rate, while adequate preparation (OR: 3.4: 95% CI: 2.9-3.9) and sedation (OR: 1.3; 95% CI: 1.1-1.6) were the strongest predictors of caecal intubation rate. Conclusions: According to our study, there is a substantial intercentre variability in the main quality indicators. Overall, the caecal intubation rate appears to be acceptable in most centres, whilst the overall level of adenoma detection appears low, with less than half of the centres being higher than 20%. Educational and quality assurance programs, including higher rates of sedation and split regimen of preparation, may be necessary to increase the key quality indicators.

Сholelithiasis ranks third in terms of the prevalence of diseases among the adult population. A complication such as choledocholithiasis occurs in up to 33% of patients with gallstone disease. Despite the improvement in treatment methods and the use of “gold” standards, the number of complicated forms of cholelithiasis has no tendency to decrease. Timely resolution of choledocholithiasis by a correctly chosen technique helps to reduce complications and increases the frequency of favorable outcomes of the disease, returning patients to social activity.That is why it is important to know and, if possible, to use various methods of rehabilitation of the common bile duct when performing modern endoscopic transpapillary interventions.

AIM: to assess the safety of endoscopic piecemeal mucosal resection (EPMR) of large epithelial colorectal lesions and to identify risk factors for tumor recurrence.PATIENTS AND METHODS: results of EPMR were evaluated in retrospective study, which was carried out in five regional endoscopic centers. The criterion for inclusion in the study was benign colorectal lesion of 20 mm and larger.RESULTS: we found that complications of EPMR occurred in 13% of cases. In 9.2% it was intraoperative bleeding, which was stopped endoscopically. Postoperative bleeding was detected in 1.2% of patients, perforation – in 2.4%. Tumor recurrence developed in 12%. We have revealed a direct correlation between tumor recurrence and intraoperative bleeding (p=0.013) and a size of lesion >4 cm (p=0.012); the inverse correlation between the tumor recurrence and the fullness of the lifting during the removal (p=0.008) and the male gender of the patient (p=0.043).CONCLUSION: significant risk factors of tumor recurrence after endoscopic piecemeal resection of large benign colorectal neoplasia were identified before the procedure (gender and tumor size) and intraoperatively (completeness of lifting and the intraoperative bleeding).
