Background

Although laparoscopic adjustable gastric bands (LAGBs) have been shown to be efficacious, their long‐term usefulness has been questioned. This study examined the fate of LAGBs in a unit with over a decade of experience in their use. Patient factors related to the need for, and timing of, band removal were investigated.

Method

A prospectively maintained database was used to identify all patients with a LAGB. Patient demographics, need for band removal and band survival were examined. Logistic regression modelling was done and Kaplan–Meier curves were calculated for band survival.

Results

Between 2000 and 2012, 674 bands were placed in 665 patients. Of these, 143 (21·2 per cent) were removed. There was no difference in rates of removal by sex (P = 0·910). The highest rates of removal were in patients aged less than 40 years (26·7 per cent), and those with a BMI greater than 60 kg/m2 (28·6 per cent). Earlier band removal was seen in younger patients (P = 0·002). Rates of removal increased linearly by earlier year of placement. Of bands placed 4 or more years previously, 35·0 per cent required removal. Eighty‐three patients (58·0 per cent) who had a LAGB removed went on to have a further bariatric procedure (band to bypass, 66; band to sleeve, 17).

Conclusion

Even in experienced hands LAGB does not appear to be a definitive solution. In a large number of patients there appears to be a finite ‘band life’, with the majority of patients requiring conversion to a further bariatric procedure.
