Obesity surgery
-
In nonobese patients, peritoneal insufflation has consistently been shown to influence parameters of preload and afterload as well as cardiac output. Obese patients have an abnormal and particular cardiovascular status. The aim of this study was to investigate the hemodynamic changes induced by an increase of intra-abdominal pressure in morbidly obese patients (MOP). ⋯ When compared to nonobese patients our obese patients tolerated the pneumoperitoneum surprisingly well, without experiencing fall in cardiac output. The hemodynamic consequences of peritoneal insufflation seem to be different in obese and nonobese patients.

Different surgical alternatives for the treatment of severe obesity have been described. The two most common surgical procedures are the Vertical Banded Gastroplasty (VBG) and the Roux-en-Y Gastric Bypass (GBP). ⋯ The procedure was fairly easy to perform. The results were excellent in terms of weight loss and postoperative complications. It is an early experience and the long-term results are still inconclusive; regular check-ups should indicate the procedure's long-term effectiveness.
