Excessive Weight Loss Following Laparoscopic Gastric Mini Bypass or Roux-En-Y Gastric Bypass Surgery

Roux-en-Y gastric bypass: limb length and weight loss.

BACKGROUND Roux-en-Y gastric bypass is a surgical technique widely used in the treatment of obesity. It is unclear, however, if the length of the biliopancreatic and alimentary limb interferes with the magnitude of weight loss. AIM To evaluate if the length of these limbs is related to the percentage of weight loss one year after surgery. METHOD One hundred and twenty obese people underwent...

Revisional Laparoscopic Gastric Pouch Resizing for Inadequate Weight Loss After Roux-en-Y Gastric Bypass

BACKGROUND Weight regain due to gastric pouch dilatation after Roux-en-Y gastric bypass (RYGB) is seen more frequently after long-term follow-up. We studied the feasibility and safety of laparoscopic pouch resizing (LPR) for dilated gastric pouch after RYGB associated with inadequate weight loss. METHODS From 1st June 2011 to 1st September 2013, patients who underwent LPR after failed RYGB we...

Kidney stone risk following Roux-en-Y gastric bypass surgery

Since the first report in 2005, Roux-en-Y gastric bypass (RYGB) surgery has been linked to a variety of metabolic changes that alter kidney stone risk. The studies with the highest level of evidence, performed in non-stone forming patients before and after RYGB, cite a number of kidney stone risk factors, including a 25% increase in urinary oxalate, a 30% decrease in urinary citrate, and reduct...

A Genetic Risk Score Is Associated with Weight Loss Following Roux-en Y Gastric Bypass Surgery

BACKGROUND Currently, Roux-en Y gastric bypass (RYGB) is the most efficient therapy for severe obesity. Weight loss after surgery is, however, highly variable and genetically influenced. Genome-wide association studies have identified several single nucleotide polymorphisms (SNP) associated with body mass index (BMI) and waist-hip ratio (WHR). We aimed to identify two genetic risk scores (GRS) ...
