Cardiovascular changes during laparoscopy. Studies of stroke volume and cardiac output using impedance cardiography.

The stroke volume and cardiac output changes in twenty-four patients undergoing laparoscopy were measured using the non-invasive technique of impedance cardiography. There was a moderate fall of stroke volume and cardiac output during intraperitoneal insufflation of carbon dioxide which was directly related to the volume of gas used. The need for caution during laparoscopy particularly in ill patients is emphasised.

Alternative operative techniques in laparoscopic Roux-en-Y gastric bypass for morbid obesity.

The only effective treatment for patients with morbid obesity is surgery. Laparoscopic bariatric surgery has become quite popular in attempts to decrease the morbidity associated with laparotomy. In this article, we describe the technical details of laparoscopic Roux-en-Y gastric bypass with three different techniques for creating the 15-cc gastric pouch. These techniques avoid upper endoscopy for the transoral introduction of the 21-mm circular stapler anvil down to the gastric pouch.
