Obesity surgery
-
Obstructive sleep apnea syndrome (OSAS) is present in 44% of patients scheduled for bariatric surgery. Respiratory dysfunction associated with this syndrome is attributable to chronic obstructive pulmonary disease (COPD) and/or obesity hypoventilation syndrome (OHS). We studied the long-term effect of bariatric surgery on weight loss, on the respiratory comorbidities associated with obesity, and on the need for non-invasive positive pressure ventilation. ⋯ Weight loss after RYGBP improved arterial blood gases, respiratory tests and polysomnographic studies. CPAP treatment can be withdrawn in most patients.

Comparative Study
Cholecystectomy during laparoscopic gastric bypass has no effect on duration of hospital stay.
Laparoscopic cholecystectomy can be safely performed at the time of laparoscopic Roux-en-Y gastric bypass (LRYGBP). This study was primarily conducted to examine whether there is any difference in the length of hospital stay and duration of operation in patients who undergo concomitant cholecystectomy with their LRYGBP. In addition, the frequency and nature of complications in the two groups were compared. ⋯ Laparoscopic cholecystectomy performed at the time of LRYGBP does not alter length of hospital stay or frequency of postoperative complications and only adds an extra half hour to total operation time.
