TL;DR
The likelihood of postoperative complications from bariatric procedures is greater for patients with low- volume surgeons or in low-volume hospitals.

Findings suggest that use of bariatric surgical procedures increased substantially from 1998 to 2003, while rates of in-hospital complications were stable and length of stay decreased.
Journal of the American College of SurgeonsImpact of gastric bypass operation on survival: A population-based analysis
528 Citations2004David R. Flum, Patchen Dellinger
Thirty-day mortality after gastric bypass is higher than previously reported and closely linked to surgeon inexperience, and a modest overall survival benefit was associated with the procedure but a marked survival advantage was noted for patients who survive to the first postoperative year.

426 Citations2004Ninh T. Nguyen, Mahbod Paya +4 more
Bariatric surgery performed at hospitals with more than 100 cases annually is associated with a shorter length of stay, lower morbidity and mortality, and decreased costs, which may be related in part to formalization of the structures and processes of care.

Increases in hospital use after surgery appear to be related to Roux-en-Y gastric bypass, and increasing Charlson Comorbidity Index score, and hospitalization in the 3-year period prior to RYGB were significantly associated with readmission within a year.

206 Citations2002G. Darby Pope, John D. Birkmeyer +1 more
Between 1990 and 1997, the annual rate of bariatric surgery in the United States more than doubled, without substantial changes in perioperative morbidity or mortality, largely associated with an increase in the use of gastric bypass procedures.
