[Morbidity and mortality related to anesthesia and surgery in 60 patients treated with bariatric surgery].
OBJECTIVE
To identify the factors predicting morbidity and mortality in patients undergoing bariatric surgery for morbid obesity in our hospital.


METHODS
Sixty bariatric surgery patients whose body mass indexes (BMI) exceeded 35 kg.m-2 were studied retrospectively. We examined the incidence of associated disease, the perioperative period, type of surgery, anesthetic technique, postoperative analgesia and the incidence of major complications.


RESULTS
Fifty-one women and 9 men (mean age 43.33 +/- 10.25 years, mean BMI 46.41 +/- 6.04 kg/m-2) were studied. The incidences of high blood pressure (55%) and obstructive sleep apnea syndrome (40%) were high. Nine patients (15%) were physical status (ASA) I, 18 (30%) were ASA II, 27 (45%) were ASA III and 6 (10%) were ASA IV. Major complications developed in 3 cases (5%) in the first 24 h and in 8 (13.33%) in the first 7 days. The mortality rate was 0% among ASA I and II patients, 3.7% (1 death) among ASA III patients, and 33.33% (2 deaths) among ASA IV patients. All who died were men. The only factor that predicted morbidity in the first week after surgery was BMI. Both morbidity in the first 24 h and mortality were associated with greater underlying disease in our patients undergoing bariatric surgery.


CONCLUSIONS
Major complications of bariatric surgery occurred in 18.3% of our patients and mortality was 5%. Physical status was a prognostic factor for both early (24 h) postoperative morbidity and mortality in our morbidly obese patients, whereas BMI was related to morbidity during the first week after surgery.
