Laparoscopic gastric banding (LGB) is the commonest bariatric procedure in Australia. The commonest complication of LGB is access port or tubing (AP/T) problems, requiring revisional surgery. The aim of this study was to document the evolving pattern of AP/T complications. All patients whose LGB procedure (AllerganTM Bands) and AP/T revision (AllerganTM port revision sets) were performed by one surgeon (1999 to 2008) were included, giving 167 AP/T revisions in 124 patients out of a total 1,928 LGB patients. All patient follow-up details were prospectively recorded and retrospectively analysed. Incidence of LGB AP/T problems was 8.7%. Mean time to first AP/T revision was 2 years. Over the last 4 years of the series, the number of LGB insertions was constant, but the number of AP/T revisions progressively increased. Twenty-seven percent of AP/T revision patients required two or more AP/T revisions. Sixty-two percent of the AP/T complications were leaks. Half the AP complications were flipping of the AP. There was no correlation of AP/T problems with any changes to port design to date. Infection rate for LGB insertion was 0.67%. The incidence of LGB AP/T complications progressively increases with duration after LGB insertion. Occurrence of one AP/T problem appears to select a subgroup more likely to experience further AP/T problems. To date, revisions of port design do not appear to have solved AP/T problems. Recent introduction of a significantly redesigned port may reduce AP/T failures.
