Perioperative outcomes of bariatric surgery in adolescents compared with adults at academic medical centers

Abstract 

Background

To compare the perioperative outcomes of bariatric surgery between adolescent (12–18 years) and adult (>18 years) patients for the treatment of morbid obesity using an administrative database.

Methods

Using the International Classification of Diseases, 9th Revision, Clinical Modification diagnosis and procedural codes, we obtained data from the University HealthSystem Consortium for 55,501 morbidly obese patients (309 adolescents and 55,192 adults) who had undergone laparoscopic or open gastric bypass, laparoscopic gastric banding, or laparoscopic gastroplasty from 2002 to 2006. The outcome measures included demographics, length of hospital stay, intensive care unit stay, 30-day readmission, morbidity, and observed and expected (risk-adjusted) mortality.

Results

The overall 30-day complication rate was significantly lower in the adolescent group (5.5% adolescents and 9.8% adults). The in-hospital and observed/expected mortality ratios were similar between groups. The greatest morbidity was associated with open gastric bypass procedures (7.6% for adolescents and 11.1% for adults) followed by laparoscopic gastric bypass (4.3% and 7.5%, respectively). Open gastric bypass in adults had the greatest observed/expected mortality ratio (1.0). In adolescents, the 30-day morbidity and mortality rate was 0% for restrictive procedures (laparoscopic adjustable gastric banding and gastroplasty).

Conclusion

Bariatric surgery in adolescents represents a small subset of all bariatric operations performed at academic centers, although the number has increased threefold since 2002. Gastric bypass is the most commonly performed bariatric procedure in adolescents. The outcomes of bariatric surgery in adolescents appear to be as safe as those in adults, with lower 30-day morbidity.
