Staple disruption in vertical banded gastroplasty.
BACKGROUND
In earlier studies of vertical banded gastroplasty (VBG), staple-line disruptions (SD) were only reported in a few per cent or less. Two recent studies have shown a significantly higher frequency of SD. To find the true frequency of SD, all patients must be examined regardless of weight outcome.


METHODS
91 consecutive patients were examined by a standardized radiological method at different postoperative intervals ranging from 6 to 48 months.


RESULTS
41 out of 91 patients developed SD. The average diameter of the disruptions was 6 mm (range 2-16 mm). During the first 2 years of follow-up, when at least 31% of the patients had developed SD, there was no significant difference in weight loss between the group with SD and the group without SD.


CONCLUSIONS
SD is an inherent problem of VBG which has been underestimated for a long period of time. An SD frequency of 45% or more within the first few years is not acceptable and changes in the VBG technique must be considered.
