Partial restrictive intestinal bypass - a retrospective analysis of post-operative patients who undergonelazzarotto surgery for obesity treatment

The bariatric surgery procedures that currently exist can provide an improvement in obesity, diabetes, and other comorbidities. However, the anatomical changes inherent to these procedures impose risks that can lead to malnutrition, bone decalcification and other pathologies. This study aimed to evaluate data from patients submitted to partial restrictive intestinal bypass surgery (Lazzarotto surgery). In this study, medical records from 129 patients and data regarding their routine exams collected during a two-year postoperative follow-up to the procedure were included. The Parretti's inclusion and exclusion criteria were used. Measured variables were family history of obesity, age, sex, body mass index (BMI), diabetes, sleep apnea, intestinal rhythm, blood count, serum levels of fasting glucose, albumin, total proteins, aspartate aminotransferase (TGO), alanine aminotransferase (TGP), total cholesterol, and triglycerides. The average initial BMI was 40.58 (SD=5.74). At six months BMI was 32.9 (SD=5.1); at twelve months BMI was 32.1 (SD=5.0); at twenty-four months BMI was 31.2 (SD=5.1). The average initial BMI was statistically different from the average BMI at 6, 12 and 24 months (p<0.0001). After two years, weight loss was statistically higher with improvement of diabetes and dyslipidemia. Albumin levels remained unchanged throughout the period. In conclusion, Lazzarotto surgery showed satisfactory results in decreasing anthropometric measurements and balancing some physiological variables.
