Pre-surgical stress and social support predict post-surgical percent excess weight loss in a population of bariatric surgery patients

We initiated a new bariatric surgery program in February 2004. Before starting the program, we initiated a systemic planning process to design, develop, and implement a comprehensive, multidisciplinary program. Between May 2004 and June 2006, 178 patients underwent Roux-en-Y gastric bypass to treat morbid obesity at our institution. We have had no pulmonary emboli and no deaths. Twenty-one patients (11.8%) developed wound infection after surgery. Thirteen patients (7.3%) developed stenosis at the gastrojejunostomy. Five patients (2.8%) bled from the gastrojejunostomy. Four patients (2.2%) developed atelectasis. Three patients (1.6%) developed an internal hernia after surgery. One patient (0.5%) developed deep venous thrombosis. Two patients (1.1%) developed small bowel obstruction from adhesions. One patient developed a leak (0.6%). By 6 months after surgery, our patients have lost an average of 85 pounds (53% excess weight loss). By 12 months, they have lost an average of 104 pounds (65% excess weight loss). A focused effort to reduce infection has dropped our wound infection rate to 0 per cent in the past 6 months. Our results indicate that with proper planning, it is possible to initiate a new program and achieve excellent outcomes. Proper planning, systematic implementation, and a focus on patient education are critical to success.

Mass Losses

Body weight, body mass index (BMI), and percent excess weight loss are used to assess patient outcomes after bariatric surgery; however, they provide little insight into the true nature of the patient's weight loss. Body composition measurements monitor fat versus lean mass losses to permit interventions to reduce or avoid lean body mass loss after bariatric surgery. A retrospective review of patients who underwent bariatric surgery between 2002 and 2008 was performed. Patients underwent body composition testing via air displacement plethysmography before and after surgery (6 and 12 months). Body composition changes were assessed and compared with the BMI. Results include 330 patients (54 male, 276 female). Average preoperative weight was 139 kg, BMI was 50 kg/m2, fat percentage was 55 per cent, and lean mass percent was 45 per cent. Twelve months after surgery average weight was 90 kg, mean BMI was 32 kg/m2, fat percentage was 38 per cent, and lean mass percent was 62 per cent. Body composition measurements help monitor fat losses versus lean mass gains after bariatric surgery. This may give a better assessment of the patient's health and metabolic state than either BMI or excess weight loss and permits intervention if weight loss results in lean mass losses.
