OBJECTIVES gastric bypass is the surgical procedure that is carried out most frequently in the treatment of morbid obesity. Stenosis of the gastro-jejunal anastomosis is a relatively frequent complication that requires endoscopic management. However, the optimal dilation technique is yet to be determined. The purpose of this study was to evaluate the safety and efficacy of dilation with a hydro...

BACKGROUND The objectives of this study were as follows: (1) to evaluate frontal sinus ostial patency following balloon dilation with the Ventera Sinus Dilation System, compared with frontal sinusotomy (Draf 2a); and (2) to compare mean blood loss and mean surgical time for frontal sinusotomy using balloon dilation compared with traditional surgical methods. METHODS A single blinded, randomiz...

t p a o Background. Completely occlusive esophageal stricures may develop after head and neck radiotherapy or sophagectomy with gastric or colonic interposition. Maor surgical intervention may be required to restore limentary tract patency when endoscopic lumen recontitution is not feasible by routine antegrade endoscopy. etrograde endoscopic lumen identification and dilation s a useful method ...

Slim endoscopes can be passed through gastrostomy tracts, but dilation is required for the passage of standard endoscopes, which may result in tract disruption. Large-diameter covered self-expandable metal stents (CSEMS) have been placed through percutaneous tracts to enable endotherapy. A 20-year-old man underwent complex thoraco-abdominal surgery following traumatic injury, resulting in a cer...
