Gastric emptying of solids after Roux-en-Y gastrectomy: is extragastric vagal innervation important?

Truncal vagotomy, antrectomy with Roux-en-Y gastrojejunostomy is frequently complicated by poor gastric emptying. The aim of this study was to determine whether the vagal denervation beyond the stomach (extragastric vagal denervation) contributes to this delay in gastric emptying. Three groups of six female mongrel dogs underwent antrectomy, Roux-en-Y gastrojejunostomy, and either truncal vagotomy, gastric vagotomy, or no vagotomy.

Atraumatic control in calcified arteries.

We have attempted distal saphenous vein bypasses for limb salvage in increasingly difficult situations. Severe calcification in the recipient artery makes vascular control and anastomosis troublesome. An atraumatic method of intraluminal control, which has been of aid in this situation, is described.
