Weight loss outcomes and complications from bariatric surgery in the super super obese



Bariatric surgery has been established as the most effective long-term treatment for morbid obesity.


We performed a retrospective review of SSO patients treated at our institute between 2008 and 2013 who underwent a laparoscopic gastric bypass (LGBP) or sleeve gastrectomy (LSG). The primary end point for this study was excess weight loss (EWL) at 1, 3, 6, and 12 months. Secondary end points included procedure length (PL), length of stay (LOS), diabetes management and postoperative complications.


We identified 135 SSO patients who underwent bariatric surgery (93 LGBP, 42 LSG) at our institute from 2008 to 2013 with a median follow-up of 49 months. The incidence of EWL > 30 % for patients in the LGBP group was 3.9, 29.0, 72.2 and 94.6 % at 1, 3, 6 and 12 months, respectively, while the incidence of EWL > 30 % in patients in the LSG group was 4.2, 25.0, 59.1 and 100 % at 1, 3, 6 and 12 months, respectively. PL was 124 ± 49 min for the LGBP group and 98 + 51 min for the LSG group (p < 0.005). LOS was on average 3.0 days (range 1–21) for the LGBP group and 3.4 days (range 1–13) for the LSG group (p = 0.41). Patients experienced a decrease in their hemoglobin A1C level by 10 % for the LGBP group and 9 % for the LSG group at 1 year (p = 0.89). Postoperative complications were seen in 15.1 % of LGBP patients and 4.8 % of LSG patients.


Bariatric surgery is feasible in the SSO patients with comparable EWL outcomes and postoperative complications to historical non-SSO patients.
