This aim of this study is to determine the risk factors in failed endoscopic retrograde cholangiography (ERC). ⋯ ERC is highly effective in treating BAS. A success rate of 73%, the highest ever reported, has been achieved. Morphology of stricture is associated with outcome of ERC. Radiological or surgical intervention should be considered for patients with pouched BAS after endoscopic treatment fails for the first time.

Our aim was to evaluate a fluorescence-based enhanced-reality system to assess intestinal viability in a laparoscopic mesenteric ischemia model. ⋯ Fluorescence-based AR may effectively detect the boundary between the ischemic and the vascularized zones in this experimental model.

To assess the contribution of hypoxia and bone marrow-derived cells to aggressive outgrowth of micrometastases after liver surgery. ⋯ Surgery-generated hypoxia in the liver causes rapid dedifferentiation of tumor cells into immature CSCs with high clone- and metastasis-forming capacity. The results help explain the phenomenon of aggressive local tumor recurrence after liver surgery and offer a potential strategy to kill aggressive CSCs by hypoxia-activated prodrugs.
