Overview

May support long-term survival benefit after gastric bypass in survivors; leaves open randomized confirmation in obesity.

Structured PICO

Does gastric bypass improve survival in obese patients?

P
Population
66,109 obese patients (age 18 to 65 years) from 1987 to 2001 in Washington State, USA.
I
Intervention
Gastric bypass (bariatric procedure)
C
Comparator
Nonoperated cohort of patients of similar age with a diagnosis of obesity or morbid obesity who did not have a bariatric procedure
O
Outcome
Short- and longterm mortality rates (survival) at up to 15 years follow-uphard clinical

Gastric bypass in obese patients is associated with a significant long-term survival benefit for those who survive the first postoperative year, though early mortality is strongly linked to surgeon inexperience.
