Postoperative rhabdomyolysis is an uncommon event. The aim of this study was to determine the incidence of rhabdomyolysis following laparoscopic obesity surgery. ⋯ Rhabdomyolysis occurred in 22.7 % of 66 consecutive patients undergoing laparoscopic bariatric surgery. Risk factors were identified: massive obesity and long duration of the operation. Early diagnosis may have significant impact on outcome by preventing or reducing the severity of complications from rhabdomyolysis. CPK level should be performed systematically after obesity surgery.

Severe sepsis syndrome (SSS) and septic shock have an associated mortality ranging from 31 to 60%. Drotrecogin alfa (activated), activated protein C (APC), has been shown in a recent trial to decrease mortality from 44 to 31% in patients with SSS and a high risk of death. We present 3 patients who developed SSS after bariatric surgery and were treated with APC as part of comprehensive therapy for sepsis. ⋯ Weight alone should not be considered a contraindication to the use of APC. Close coordination between the intensivist and surgeon is recommended for bariatric surgery patients with SSS, so that a rapid determination can be made as to the patient's risk of death and eligibility to receive APC.

Obstructive sleep apnea (OSA) is common in morbidly obese patients, with a reported prevalence from 12 to 40%. Preoperative diagnosis of OSA is important for both perioperative airway management and the prevention of postoperative pulmonary complications. BMI has been reported to be an independent risk factor, and has been used recently in scoring systems to help predict OSA. Our hypothesis was that OSA is highly prevalent in patients presenting for bariatric surgery, and that BMI alone is not a good predictor of the presence or absence of sleep apnea. ⋯ In this large patient cohort, sleep apnea was prevalent (77%) independent of BMI, and most cases were not diagnosed before bariatric surgical consultation. These data support the use of routine screening polysomnography before bariatric surgery.
