Abstract
Background
Laparoscopic adjustable gastric bands (AGB) are converted at high rates to secondary
bariatric procedures. The available literature on the safety of converting in one-
versus two-stage process has not included large databases.
Objective
To evaluate the safety of a one- versus two-stage conversion of AGB.
Setting
Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP),
United States.
Methods
The MBSAQIP database for the years 2020 and 2021 were evaluated. One-stage AGB conversions
were identified using Current Procedural Terminology codes and database variables.
Multivariable analysis was performed to determine if one- or two-stage conversions
were associated with 30-day serious complications.
Results
There were 12,085 patients who underwent conversion from previous AGB to SG (63.0%)
or RYGB (37.0%), of which 41.0% underwent conversion in one-stage and 59.0% in two-stages.
Patients who underwent two-stage conversions had higher BMIs. Rates of serious complications
were higher for patients undergoing RYGB compared to SG (5.2 vs 3.3%, p < 0.001),
however, were similar between one-stage and two-stage conversions in both cohorts.
In both cohorts, there were similar rates of anastomotic leaks, postoperative bleeding,
reoperation, and readmissions. Mortality was rare and similar between conversion groups.
Conclusions
There was no difference in outcomes or complications in 30-days between one- and two-stage
conversions of AGB to RYGB or SG. Conversions to RYGB have higher complication and
mortality rates than to SG, but there was no statistically significant difference
between staged procedures. Either one- or two-stage conversions from AGB are equivalent
in safety.
