Evaluation of the positioning of the tip of the Veress needle during creation of closed pneumoperitoneum in pigs.

Purpose: Erroneous punctures and insufflations are frequent with the use of the Veress needle. Mistaken injections of gas in the preperitoneal space are not rare. The purpose of this research is to evaluate the correct positioning of the tip of the needle during creation of pneumoperitoneum.

[One layer sutures of digestive tract knotted in the lumen, in dogs: perforating stitch versus serosubmucosal suture].

Objective: To compare hand sewn digestive tract single layer anastomosis with knots tied in the lumen: total stitches versus serosubmucosal.

Methods: Six mongrel dogs were submitted to laparotomy, each one with two transversal jejunum sections, 30 and 70 cm far from Treizt angle and suture, serosubmucosal and total stitches, both with knots tied in the lumen, over the mucosa, at the posterior wall. After slaughter (7th post-operative day) was evaluated the peritoneal adhesions at posterior wall.
