Biliopancreatic diversion in a renal transplant patient.

Surgery is usually the only solution to modify the evolution of morbid obesity and resolve the associated co-morbidities. There is very little written regarding malabsorptive surgery and transplantation. A 48-year-old male with hypertension, hyperuricemia and obesity underwent renal transplantation in 1994 for renal amyloidosis. He was maintained on oral immunosuppressive cyclosporine. The patient developed uncontrollable hypertension, hyperlipemia, hyperglycemia and increasing weight to a BMI of 44. Thus, in December 2004, he underwent biliopancreatic diversion (BPD). After 18 months follow-up, he has lost 85% of his excess weight, and his hypertension, hyperglycemia and hyperlipemia are markedly improved. Renal function was not modified, nor were the levels of cyclosporine. He has had no complications derived from the BPD, and has a better quality of life.

Total thyroidectomy is the surgical treatment of choice for differentiated thyroid carcinoma. Despite this surgical treatment, locoregional and distant metastases can develop. Postoperative follow-up should include determination of serum thyroglobulin levels and radioactive iodine (131I) and thallium (201Tl) whole body scans. These techniques are more reliable in patients who have undergone total thyroidectomy. We stress the importance of routine medical follow-up after surgical treatment of thyroid cancer, even in the absence of symptoms.

Effects of weight loss after biliopancreatic diversion on metabolism and cardiovascular profile.

BACKGROUND: Obesity is associated with increased prevalence of cardiovascular risk factors. Biliopancreatic diversion (BPD) for morbid obesity has been reported to produce anemia and malnutrition in short-term follow-up. The aim of our study was to analyze the effect of weight reduction on cardiovascular profile, renal function and nutritional status. METHODS: 35 morbidly obese patients underwent BPD. We analyzed the presence of cardiovascular risk factors, renal status, proteinuria and nutritional status before and 1 year after BPD. RESULTS: Excess weight loss was 67% at 1 year after BPD. All cardiovascular risk factors (hypertension, diabetes, hyperlipidemia) improved during follow-up. We could not find any relevant signs of malnutrition in the patients. Microalbuminuria decreased and proteinuria disappeared after weight loss. We observed less urinary calcium and citrate excretion, with an increase in oxaluria, but these changes did not increase the incidence of renal stones. CONCLUSIONS: BPD was followed by improved cardiovascular profile and a lower pro-inflammatory state. BPD did not produce significant malnutrition, anemia or renal stone disease.
