title: Laparoscopic bariatric surgery for the treatment of severe hypertriglyceridemia.
abstract: BACKGROUND
  It is well established that severe hypertriglyceridemia can lead to pancreatitis. At present, medical treatment for patients with severe hypertriglyceridemia and repeat pancreatitis attacks is not adequate. The aim of this study was to assess the effectiveness of laparoscopic bariatric surgery in these patients.
  
  
  METHODS
  A review of 20 morbidly obese patients with severe hypertriglyceridemia (a triglyceride level of >1000 mg/dL) who received laparoscopic bariatric surgery was performed. The study population comprised 14 males and six females, with an average age of 35.0 years (range 24-52 years), and the mean body mass index was 38.2 kg/m(2) (range 25-53 kg/m(2)). The preoperative mean plasma triglyceride level was 1782.7 mg/dL (range 1043-3884 mg/dL). Four patients had a history of hypertriglyceridemic pancreatitis and 13 patients had associated diabetes.
  
  
  RESULTS
  Of the 20 patients, 17 (85%) received gastric bypass, whereas three (15%) received restrictive-type surgery. Laparoscopic access was used in all of the patients. Hypertriglyceridemia in morbidly obese patients was more commonly associated with male sex and a poorly controlled diabetic state. The mean weight reduction was 25.5% 1 year after surgery, with a marked improvement in diabetes management. As early as 1 month following surgery, the plasma mean triglyceride levels had decreased to 254 mg/dL (range 153-519 mg/dL), and this was further reduced to mean levels of 192 mg/dL (range 73-385 mg/dL) 1 year after surgery. One patient developed acute pancreatitis during the perioperative period, but none of the patients suffered an episode of pancreatitis in the follow-up period (from 6 months to 13 years).
  
  
  CONCLUSIONS
  Bariatric surgery can be successfully used as a metabolic surgery in severe hypertriglyceridemia patients at risk of acute pancreatitis. However, control of triglyceride levels prior to bariatric surgery is indicated.
