Liver Volume and Visceral Obesity in Women With Hepatic Steatosis Undergoing Gastric Banding

To investigate the relationships between visceral obesity and hepatic steatosis in obese patients undergoing adjustable silicone gastric banding with the LAP-BAND.

Method

Six premenopausal, morbidly obese women with an ultrasonographic diagnosis of liver steatosis were evaluated before surgery and 8 and 24 weeks after surgery. Liver volume and body fat distribution were simultaneously analyzed by total-body multislices magnetic resonance imaging.

Results

Before surgery, the only variable found to be correlated with liver volume was visceral adipose tissue volume. Weight loss was 9.9 +/- 3.8 kg in the period from 0 to 8 weeks and 7.1 +/- 4.9 kg in the the period from 8 to 24 weeks. Total fat showed a statistically significant reduction of 6.2 +/- 4.0 liters in the 0- to 8-week period and a further significant reduction of 7.7 +/- 3.9 liters in the 8- to 24-week period. Visceral adipose tissue showed a statistically significant reduction of 1.0 +/- 0.9 liters in the 0- to 8-week period but only a further, not significant reduction of 0.6 +/- 0.7 liters in the 8- to 24-week period. The relative reduction of visceral fat in the 0-to 8-week period was higher than the relative reduction of total fat. Liver volume also showed a statistically significant reduction of 0.24 +/- 0.26 liters in the first phase of weight loss, corresponding to a relative reduction of 12.3 +/- 10.6%. During the 8- to 24-week period, liver volume was substantially stable.

Discussion

Hepatomegaly was associated with visceral obesity in morbidly obese women with liver steatosis. In the phase of rapid weight loss after gastric surgery, a preferential mobilization of visceral fat, compared with total adipose tissue, occurred. This preferential visceral fat loss was associated with a significant reduction in liver volume.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2017 Bariatric-Surgery.Info - Terms - Contact - Information - Resources
