Effects of N-acetylcysteine on the inflammatory response and bacterial translocation in a model of intestinal obstruction and ischemia in rats.

Purpose: To evaluate effect of N-acetylcysteine (NAC) associated with Ringer lactate or hypertonic saline in inflammation and bacterial translocation on experimental intestinal obstruction (IO).

Methods: Wistar rats was subjected to IO. Six or 24 hours after, rats were subjected to enterectomy and fluid resuscitation: IO, RL (subjected to the same procedures but with fluid resuscitation using Ringer's lactate solution); RLNAC (added NAC to Ringer's solution); and HSNAC (surgical procedure + fluid reposition with 7.

Bacterial translocation and mortality on rat model of intestinal ischemia and obstruction.

Purpose:: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival.

Methods:: After anesthesia, Wistar rats was subject to laparotomy, intestinal ischemia and obstruction through an ileal ligature 1.5cm of ileum cecal valve; and the mesenteric vessels that irrigate upstream of the obstruction site to approximately 7 to 10 cm were ligated.

Treatment of mid-line abdominal wall hernias with the use of endo-stapler for mid-line closure.

Introduction: Minimally invasive videosurgery has modified anatomy dissection of diseases that are treated operatively. However, the benefit of this method has been delayed due to the lack of development of technologies and articulated movements for the abdominal wall, demanding the need for investments and time for solidification. This approach to repair the abdominal wall is based on the Rives-Stoppa principles.

[Modified robot assisted Rives/Stoppa videosurgery for midline ventral hernia repair].

Background: The weakness of the linea alba can be caused by congenital and aquired factors. The conventional procedure to correct these imperfections generally involve large incisions with big detachments of the skin and subcutaneous tissue. The use of videosurgery for the repair of these weaknesses is still controversy.

Brazilian experience in obesity surgery robot-assisted.

Background: Minimally invasive techniques were associated with bariatric surgery, leading to a decrease in aggression to the organs and systems. Robotic surgery is a new possibility within the concept of minimal invasion.

Aim: To evaluate the initial experience of robotic surgery for obesity.
