BACKGROUND Although the use of a subepithelial connective tissue graft (SCTG) in conjunction with a coronally advanced flap (CAF) is a widely performed periodontal procedure, the creation of a partial-thickness flap can incur a risk of perforation or overthinning of the flap itself. Therefore, the aim of the present trial is to compare the efficacies of(More)

The patient presented with pain and jaundice and ultrasonography disclosed multiple common bile duct stones, cystic dilatation of the extrahepatic biliary tree and a mass in the right lobe of the liver.

Endoscopic dilatation and stenting are the procedures of choice in the treatment of oesophago-gastric anastomotic stricture following oesophagectomy, leading to immediate relief of dysphagia with a low procedure-related risk. Prosthesis displacement is a described late complication, easy detected and sorted out whenever possible with endoscopic retrieval. A(More)
Infected vascular grafts are associated with very high rates of limb loss and mortality. "Classic" treatment has invariably included graft excision. Recent reports have suggested that a more conservative approach may be indicated in selected cases, leaving the graft in place and using an aggressive local treatment associated with appropriate intravenous(More)
