Within the limitations of a modest sample size, CBP appears to be inadequate treatment for the removal of diminutive polyps.

Our EVBL-induced ulcer bleeding rate was low, but associated with significant mortality. Highest rates were observed following EVBL for acute variceal haemorrhage, for which EVBL is unavoidable. The incidence was lower following prophylactic EVBL, with the MELD score being the predominant risk factor. Reflux oesophagitis requires further investigation as a potentially modifiable risk factor for EVBL-induced ulcer bleeding.

NBI detected fewer lesions than CE in chronic colitis; however, most were not dysplastic. There was a nonsignificant trend in favor of CE for detection of dysplasia. At present, NBI cannot be recommended as an alternative to CE for dysplasia surveillance in colitis.

This novel ID-FCSEMS has a high clinical success and low complication rate, and in particular, there was only one case of stent migration. As a result, this stent type is preferred to traditional metal stents for treating AS after OLT.
