Background: Nutritional status during pregnancy and the effects of nutritional deficiencies on pregnancy outcomes after bariatric surgery is an important issue that warrants further study. The objective of this study was to investigate pregnancy outcomes and nutritional indices after restrictive and malabsorptive procedures.

Methods: We investigated pregnancy outcomes of 113 women who gave birth to 150 children after biliopancreatic diversion (BPD), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) between June 1994 and December 2011.

Background: This study presents late results of a previously published 2-year prospective comparison between Roux-en-Y gastric bypass (RYGBP) versus biliopancreatic diversion with Roux-en-Y gastric bypass (BPD-RYGBP) in an exclusively non-superobese population.

Methods: From a cohort of 130 patients with a BMI of 35-50 kg/m(2), 65 were randomly selected to undergo RYGBP and 65 to BPD-RYGBP. All underwent follow-up evaluation at 1, 3, 6, and 12 months postoperatively and every year thereafter.

Background: Over the past 14 years, we have used different malabsorptive bariatric operations to treat super-obesity. We compared the efficacy and safety of our preferred procedure for the last 8 years with previous methods used in super-obese.

Methods: Our first procedure was distal Roux-en-Y gastric bypass (distal RYGBP) (gastric pouch 15 ± 5 mL, 80 cm biliopancreatic limb, 100 cm common limb [CL]).

Objective: To evaluate the safety and effectiveness of revisional bariatric surgery at a tertiary institution. Revisional bariatric operations for unsuccessful weight loss or intolerable complications following the primary intervention are increasing.

Design: Case series from a prospective database.

Objective: To investigate the effect of marked weight loss after long limb-biliopancreatic diversion (BPD-LL) on bone mass and serum calcium, 25-OH-vitamin D, and PTH levels in relation to calcium supplementation.

Background Data: BPD is the most effective type of bariatric surgery, but it is followed by bone mass loss, mainly attributed to calcium and vitamin D malabsorption leading to secondary hyperparathyroidism.

Methods: Two groups, each consisting of 26 healthy, morbidly obese, premenopausal women, underwent BPD-LL.

Aim: To evaluate and present our experience with laparoscopic Roux en Y gastric bypass (RYGB) in a selected patient population.

Methods: A cohort of 130 patients with a body mass index (BMI) between 35 and 50 kg/m(2) were evaluated in relation to postoperative morbidity, weight loss and resolution of co-morbidities for a period of 4 years following laparoscopic RYGB.

Results: Early morbidity was 10.

Background: Super-obese patients with BMI > or = 70 kg/m(2) present a special subgroup among the obese population due to the higher incidence of severe comorbidities and increased technical difficulties in perioperative management. The optimal surgical approach still remains controversial.

Methods: From January 2002 to October 2007, 68 super-obese patients with BMI > or = 70 kg/m(2) (75.

Background: Super-obese patients with many co-morbidities present a challenge in bariatric surgery because of the high perioperative morbidity and mortality. The BioEnterics intragastric balloon (BIB) is an endoscopic device used preoperatively to induce weight loss to reduce the risk of surgery for morbid obesity.

Methods: From November 2003 to April 2006, the BIB was endoscopically placed in 26 high-risk super-obese patients with a mean body mass index of 65.

Background: In the non-superobese population, an agreement has not been made as to the optimal bariatric operation. The present study reports the results of a prospective comparison of Roux-en-Y gastric bypass (RYGBP) and a variant of biliopancreatic diversion (BPD) in a non-superobese population.

Methods: From a cohort of 130 patients with BMI 35 to 50 kg/m(2), 65 patients were randomly selected to undergo RYGBP and 65 to undergo BPD.

Background: In the non-superobese population, consensus is currently unavailable in bariatric surgery. We report the results of a prospective comparison of vertical banded gastroplasty (VBG) and Roux-en-Y gastric bypass (RYGBP) in a non-superobese population.

Methods: From 1994 to 2000, 179 patients with clinically severe obesity underwent various surgical procedures in our department.

The aim of this study was to determine prospectively the efficacy and safety of the biliopancreatic diversion with Roux-en-Y gastric bypass (BPD with RYGBP) procedure used as the primary bariatric procedure in super obese patients. The main characteristics of the BPD with RYGBP procedure were a gastric pouch of 15 +/- 5 ml, biliopancreatic limb of 200 cm, common limb of 100 cm, and alimentary limb of the remainder of the small intestine. From June 1994 through July 2003, 132 super obese patients (body mass index [BMI]: 57 +/- 7), with an incidence of comorbidities 6 +/- 2 per patient, underwent BPD with RYGBP and subsequent follow-up.

Background: Patients undergoing either Roux-en-Y gastric bypass (RYGBP) or biliopancreatic diversion (BPD) with RYGBP are at risk of developing metabolic sequelae secondary to malabsorption. We compared the differences in nutritional complications between these two bariatric operations.

Methods: A retrospective analysis of a prospective database was done.
