APC is highly effective in all patients with mild radiation proctitis and in the majority of those with severe disease, providing long-lasting clinical remission.

Surgery improves constipation and is associated with a higher degree of patient satisfaction, but the quality of studies was very variable. Future controlled trials should examine the ideal therapeutic approach for different patient groups.

Supragastric belch is the prominent belching pattern in patients with excessive belching. Supragastric belches almost ceased at night suggesting the presence of a behavioral disorder. There were no diurnal changes in the rate of gastric belches.

Ageing does not affect the completion rate and the quality of bowel preparation for VCE. However, elderly patients have fewer normal studies and more angiodysplasias and tumors in the small bowel.

Background. Quality monitoring and improvement is prerequisite for efficient colonoscopy. Aim. To assess the effects of increased sedation administration on colonoscopy performance. Materials and Methods. During Era 1 we prospectively measured four colonoscopy quality indicators: sedation administration, colonoscopy completion rate, adenoma detection rate, and early complications rate in three cohorts: cohort A: intention for total colonoscopy cases; cohort B: cohort A excluding bowel obstruction cases; cohort C: CRC screening-surveillance cases within cohort B. We identified deficiencies and implemented our plan to optimize sedation. We prospectively evaluated its effects in both short- (Era 2) and long-term period (Era 3). Results. We identified that sedation administration and colonoscopy completion rates were below recommended standards. After sedation optimization its use rate increased significantly (38.1% to 55.8% to 69.5%) and colonoscopy completion rate increased from 88.3% to 90.6% to 96.4% in cohort B and from 93.2% to 95.3% to 98.3% in cohort C, in Eras 1, 2, and 3, respectively. Adenoma detection rate increased in cohort C (25.9% to 30.6% to 35%) and early complications rate decreased from 3.4% to 1.9% to 0.3%. Most endoscopists increased significantly their completion rate and this was preserved long-term. Conclusion. Increased sedation administration results in long-lasting improvement of colonoscopy quality indicators.
