The paradox of Zeno in bariatric surgery weight loss: Superobese patients run faster than morbidly obese patients, but can't overtake them

INTRODUCTION: Superobesity (SO) is defined as a BMI > 50 Kg/m(2), and represents the extreme severity of the disease, resulting in a challenge for the surgeons. METHODS: In this retrospective study we aimed to compare the outcomes of SO patients compared to morbidly obese (MO) patients. RESULTS:...

Sumario:INTRODUCTION: Superobesity (SO) is defined as a BMI > 50 Kg/m(2), and represents the extreme severity of the disease, resulting in a challenge for the surgeons. METHODS: In this retrospective study we aimed to compare the outcomes of SO patients compared to morbidly obese (MO) patients. RESULTS: We included in this study 154 MO patients, with a median preoperative BMI of 40.8 kg/m(2), and 19 SO patients with median preoperative BMI of 54.9 kg/m(2). The MO patients underwent sleeve gastrectomy (SG) in 62 (40.3%) cases, laparoscopic Roux-and-Y gastric bypass (LRYGBP) in 85 (55.2%) cases and One-Anastomosis Gastric Bypass (OAGB) in 7 (4.5%) cases. underwent OAGB. The patients in the SO group were submitted to SG in 11 (57.9%) cases, LRYGBP in 5 (26.3%) cases, and OAGB in 3 (15.8%). At 24-month follow-up, an excess weight loss (EWL) >50% was achieved in 129 (83.8%) patients in the MO group and in 15 (78.9%) in the SO group (p = 0.53). A BMI < 35 kg/m(2) was achieved in 137 (89%) patients in the MO group and from 8 (42.2%) patients in the SO group (p < 0.001). The total weight loss was significantly directly related to the initial BMI. Superobesity was identified as independent risk factor for surgical failure when considering the outcome of BMI < 35 kg/m(2). DISCUSSION: Our study confirms that, although SO patients tend to gain a greater weight loss than MO patients, they less frequently achieve the desired BMI target. In this setting, it should be necessary to re-consider malabsorptive procedures as first choice.
