Symptoms of patients obese heart failure improved after Bariatric Surgery

PharmaLive.com (14 November 2010) - a small Mayo clinical study found that obesity morbid congestive heart failure patients undergoing Bariatric Surgery gain lasting and significant improvements in symptoms of disease and the quality of life. The results were presented on 15 November at the American Heart Association scientific sessions 2010 in Chicago.

"This tells us that Bariatric Surgery can be part of the treatment of patients with heart failure and obesity if no major contraindication to surgery - and that this could be particularly important for patients with significant obesity," says principal investigator of the study, cardiologist Francisco Lopez-Jimenez, MD

He warned, however, that because the study tested the effects of surgery Bariatric patients only 13, "should consider these preliminary results suggestive of benefits, but additional research is needed to confirm these results."

Even if one third of patients with heart failure are obese, it seems that cardiologists do not often reference obese patients suffering from heart failure for surgery Bariatric, said Mr. Jimenez Lopez.

The research team examined the results of 13 patients, 44 and 64 years who received Bariatric Surgery at the Minnesota between 1990 and 2005, Mayo Clinic as well as congestive heart failure, six patients aged 52-72, which was followed by Mayo Clinic nutrition and has not received the surgery.

In the group who received surgery mean body mass index (BMI) was 53 and in the Group of comparison, it was 42.After a four-year follow-up average BMI dropped 37 surgery group and pink group at 45.

Based on surveys of patients, the researchers found that the quality of life has been improved considerably patients who received surgery Bariatric, that heart failure patients who do not have.Researchers also found that symptoms such as swelling in the legs and labored breathing during exercise only in the surgery group.

Mr. Lopez-Jimenez says that the benefits of health observed in patients who have had bariatric surgery has produced even though most remained overweight."These patients had levels very advanced obesity before surgery, and even though they have lost large amounts of weight, most remains obèse.ainsi, these results suggest that advantage does not patients require reach a normal weight,"he said.""

More fat around internal organs may mean more complications after liver surgery

PharmaLive.com (16 November 2010) - amount of intra-abdominal fat seems to be associated with the risk of complications after major surgery of the liver, according to an article published in the November issue of the archives of surgery, one of the JAMA/Archives Journals. However, appearing in overweight or who have a high body mass index (BMI) were not associated with increased post-operative risk.

Approximately 65% of the u.s. population is currently overweight, half of those eligible as obese, according to background information in the article. Increase the frequency of obesity "surgeons review requires more critical of the effect of overweight and obesity on their patients," write the authors. " Literature currently presents mixed conclusions about the effect of overweight and obesity on various surgical populations with different measures of obesity used in these studies.»

Katherine Morris, M.D. and his colleagues at Memorial Sloan - Kettering Cancer Center in New York, studied 349 patients undergoing a surgical removal of part of the liver from June 1996 and November 2001. Computed tomography (CT) analysis before surgery were used to estimate the amount of fat as perinephritic, a measure of fat around the kidneys, which has been used as a substitute for the intra-abdominal fat.In addition, BMI patients was calculated using data size and poids.Les authors have also used computed tomography to measure external abdominal fat. Complications were followed by the cancer centre database.

After the major operations of liver, 230 patients (65.9%) have complications and nine (2.6%) patients died.The average duration of hospital stay was 10.8 days.

As measured by the amount of grease around the kidney patients with intra-abdominal fat than were more likely to have complications, including serious complications, longer length of hospital stay, and were more likely to die within 30 days that patients with less material grasses.Les patients with a higher mass index (BMI) body had procedures which took over time; However, BMI and external abdominal fat measures not were not associated with complications rate, the onset of serious complications, the duration of the stay or the risk of death within 30 days.

IMC appears to be a poor measure obesity puts abdominal surgery patients at risk type, the authors note.""As defined as perinephritic grease unique and simple substitution, intra-abdominal fat could serve as a risk stratifying patients for mortality, the rate of complication, severity of complications and increasing length of stay," they write.

"This should help surgeons be better able to identify patients at high risk and, conversely, not reject a transaction based on the presumed someone external obesity risk."Now that most of our patients taken into account for a major upper abdominal resection will preoperative CT scan, provided as perinephritic looking fat rich information is easily determined and should not be ignored.
