Bone metabolism and fracture risk after Biliopancreatic Diversion.

Background: Bariatric surgery (BS) is an effective treatment. However, there have been concerns regarding the negative effect on the bone. The aim of this study was to assess changes in bone metabolism and the risk of fracture after biliopancreatic diversion (BPD).

Secondary Hyperparathyroidism in Patients with Biliopancreatic Diversion After 10 Years of Follow-up, and Relationship with Vitamin D and Serum Calcium.

Background: Secondary hyperparathyroidism (SHPT) is a matter of concern after biliopancreatic diversion (BPD). The aim of this study was to investigate the relationship between SHPT, 25(OH)D, and calcium after BPD.

Design: A retrospective analysis in obese patients after BPD performed between 1998 and 2016.

Biliopancreatic Diversion for Severe Obesity: Long-Term Effectiveness and Nutritional Complications.

Background: Bariatric surgery is currently the treatment of choice for those patients with severe obesity, but the procedure of choice is not clearly established. We describe weight loss and nutritional parameters in severely obese patients after biliopancreatic diversion for 10 years of follow-up.

Methods: Patients were followed by the same multidisciplinary team, and data are shown for 10 years.

[Upper endoscopy findings in obese morbid patients candidates for bariatric surgery].

Introduction: Body mass index has been associated with the presence and severity of various gastrointestinal symptoms. The aim of the study was to analyze the endoscopic findings and gastric histology of morbidly obese candidates for bariatric surgery.

Methods: We retrospectively included patients undergoing bariatric surgery at the Hospital de León from March 2005 to April 2013.

Insulin resistance and metabolic syndrome are related to non-alcoholic fatty liver disease, but not visceral adiposity index, in severely obese patients.

The visceral adiposity index (VAI) is a marker of visceral fat distribution and dysfunction. Visceral adiposity is related to nonalcoholic fatty liver disease (NAFLD); however, there is some controversy regarding the association between VAI and NAFLD.The aim of this study was to analyse the relationship between VAI and NAFLD and to describe the related factors in severely obese patients.

[Effects of preoperative weight loss with a very low calorie diet (VLCD) on weight loss after biliopancreatic diversion in patients with severe obesity].

Background: Weight loss before bariatric surgery, achieved by means of a very low calorie diet (VLCD) has been recently reported to be related to a lower rate of postoperative complications. However, it is controversial if preoperative weight loss after VLCD could improve postoperative weight loss.

Aims: To assess the effectiveness of a preoperative VLCD for 6 weeks in weight loss one year after bariatric surgery.
