Cost-effectiveness of trans-nasal endoscopic sphenopalatine artery ligation vs arterial embolisation for intractable epistaxis: Long-term analyses.

Objectives: Trans-nasal endoscopic sphenopalatine artery ligation (TESPAL) and endovascular arterial embolisation both provide excellent success rates for intractable epistaxis. Recent economic models suggest that TESPAL could be a cost-saving strategy. Our main aim was to perform cost-effectiveness analyses on TESPAL compared with embolisation to treat patients with epistaxis.

Stapled aortic anastomoses: a minimally invasive, feasible alternative to videoscopic aortic suturing?

Widespread applications of totally laparoscopic aortic reconstructions have been limited by the long cross-clamp time required to suture the aortic anastomosis despite improvement in instrumentation. The authors' hypothesis was that a "one-step anastomosis concept" using an intraluminal stapler would allow shorter cross-clamp time but similar patency and imperviousness as videoscopic suturing techniques. An intraluminal stapler (Endopath-ILS, Ethicon) with a modified anvil was used to perform videoscopic-assisted thoracic aorta-to-iliac artery bypass with a 21 mm by 8 mm polytetrafluoroethylene (PTFE) graft in 22 sheep through a minimally invasive approach using a 5 cm thoracotomy.
