Mortality has been reported to complicate gastric bypass, with common causes of death attributable to anastomotic leaks, sepsis, hemorrhage, and bowel obstruction. We evaluated autopsy reports from 10 patients having undergone gastric bypass. Medical records were reviewed to identify comorbidities. Data of interest included preoperative electrocardiogram (EKG) abnormalities, cause of death, body weight, anastamosis appearance, heart weight, extent of coronary artery disease, ventricular size, liver weight, and gall bladder status. A total of 7 men and 3 women were autopsied. Average age was 40 years (range, 30-49 years), and mean body mass index at autopsy was 60.3 kg/m(2) (range, 33.2-80.9 kg/m(2)). Evidence of anastomotic leaks was present in 7 cases, resulting in 4 deaths. Death was attributed to pulmonary embolism in one case. There were 5 cardiac-related deaths, all attributed to arrhythmias. Microscopic evidence of coronary artery disease was observed in 6. Cardiomegaly was seen in all patients, left ventricular hypertrophy in 8, right ventricular hypertrophy in 3, and hepatomegaly in all 10. Nine patients were status post cholecystectomy. Of the 8 preoperative EKG available, abnormalities were identified in 5. After gastric bypass, death was attributed to cardiac-related causes, pulmonary embolism, and operative complications. A significant proportion of cardiac-related deaths occured in the absence of atherosclerosis. Most patients had preoperative EKG abnormalities. As a high incidence of cardiomegaly was observed, operative stress associated with the procedure may increase the risk of arrhythmia in morbid obesity. Consequently, in morbidly obese patients, a detailed preoperative cardiovascular evaluation is warranted to reduce postoperative mortality. |
