LS and UC are clearly the safest and most efficient methods of coagulation, whereas ME and BE could cause serious clinical and histological complications. We found histological evidence that UC causes a slightly greater inflammatory response than LS, and the clinical implications of this warrant further investigation.

Serum sex hormone levels were measured preoperatively in 57 morbidly obese patients (19 men and 38 premenopausal women) and 12 months after vertical banded gastroplasty. In the male group, there was a significant decrease in estradiol and an increase in follicle-stimulating hormone (FSH), total testosterone and sex-hormone-binding globulin (SHBG). Among female patients, a significant decrease in estradiol, total and free testosterone and an increase in FSH and SHBG was found. Irregular menses present preoperatively in 5 women were corrected after successful weight loss. In conclusion, altered sex hormonal levels and gynecologic abnormalities associated with morbid obesity are corrected with adequate weight loss following vertical banded gastroplasty.

Occult cancer is fairly common in patients with idiopathic DVT, but the routine use of extensive diagnostic studies for its detection remains to be validated by further prospective studies.
