A randomized comparison of a new flexible bipolar hemostasis forceps designed principally for NOTES versus a conventional surgical laparoscopic bipolar forceps for intra-abdominal vessel sealing in a porcine model.

Background: Current devices for hemostasis in flexible endoscopy are inferior to methods used during open or laparoscopic surgery and might be ineffective for natural orifice transluminal endoscopic surgery.

Objective: To compare new flexible bipolar forceps (FBF), designed principally for natural orifice transluminal endoscopic surgery, with laparoscopic bipolar forceps (LBF) for hemostasis of intra-abdominal porcine arteries.

Setting: Surgical laboratories in Europe and the United States.

Optimizing bipolar electrocoagulation for endoscopic hemostasis: assessment of factors influencing energy delivery and coagulation.

Background: Few data inform decisions on the optimal bipolar electrocoagulation (BPEC) technique.

Objectives: To assess how technical factors influence energy delivery and coagulation.

Design: Prospective, randomized study in experimental models: meat, live pig mesenteric arteries.
