Biliopancreatic Diversion in the Surgical Treatment of Morbid Obesity: Long-Term Results and Metabolic Consequences

Purpose In the multidisciplinary therapeutic approach to obesity, bariatric surgery is considered the most effective treatment in weight reduction and the decrease in associated comorbidities. The objective of this work is to describe the long-term clinical and metabolic results in obese patients undergoing biliopancreatic diversion (BPD) according to Scopinaro’s technique. Materials and Methods Patients undergoing surgery were followed by the same multidisciplinary team in a study period of 15 years (1999–2015). A retrospective study based on a prospective database was designed, where data on the evolution of obesity-related diseases and nutritional parameters were studied. Results Two hundred seventy-seven patients were collected; 75.5% were women. The preoperative body mass index (BMI) decreased from 52.5 kg/m 2 to 34.9 kg/m 2 10 years after surgery. A resolution or improvement of diabetes has been observed in 85.38% of the patients; a decrease in arterial hypertension and obstructive sleep apnea syndrome were in 65.61% and 89.14%, respectively. Throughout the monitoring of the sample, protein malnutrition increased, from 1.8% after the first year of surgery to 4.5% 10 years after the operation. Conclusion Even if Scopinaro’s technique is beginning to be replaced by other malabsorptive techniques, it can still be considered as an effective surgical procedure in terms of weight loss, quality of life, and evolution of obesity-related diseases. In order to avoid nutritional deficiencies, the operated patients need a strict follow-up and a supplementation adjusted to the technique.
