Prospective evaluation of 114 obese patients (96 women, 18 men) underg
oing vertical banded gastroplasty over a 5-year period was undertaken.
The age range was 17-58 (median 37) years, median weight 119.3 (range
79-216) kg, mean(s.d) proportion of excess body-weight 104.1(34.9) pe
r cent and median body mass index (BMI) 44.8 (range 33.2-77.7) kg/m(2)
. Three gastric outlet stoma circumferences were used: 5.5 cm (31 pati
ents), 5.0 cm (28) and 4.75 cm (55). A total of 109 patients (95.6 per
cent) were available for follow-up. At 1 year after operation, 54 pat
ients (59 per cent) had lost greater than 50 per cent of excess body-w
eight. No patient lost less than 25 per cent of excess body-weight, an
d the median BMI was 32.5 (range 21.3-47.8) kg/m(2). The operative mor
tality rate was zero, but three patients (2.6 per cent) with gastric l
eakage required surgical revision. Vertical banded gastroplasty is a r
elatively safe and simple procedure that produces significant and sust
ained weight reduction in the majority of morbidly obese patients.
