Frequency of cholelithiasis in need of surgical or endoscopic treatment a decade or more after Roux-en-Y gastric bypass.

Background: Symptomatic cholelithiasis requiring treatment is a known side effect after Roux-en-Y gastric bypass (RYGB), but reported rates vary greatly. The objectives for this study were to evaluate the long-term frequency of surgical or endoscopic treatment for symptomatic cholelithiasis 10-15 years after RYGB and its relation to self-reported abdominal pain.

Methods: Observational data from 546 patients who underwent RYGB at public hospitals in Central Norway between March 2003 and December 2009 were analyzed.

The Long-Term Impact of Postoperative Educational Programs on Weight Loss After Roux-en-Y Gastric Bypass.

Purpose: Roux-en-Y gastric bypass (RYGB) is a well-documented treatment of severe obesity. Attending postoperative educational programs may improve the outcome. The aim of this study was to evaluate whether participation in educational programs lasting 2-3 years after RYGB influences long-term weight loss, weight regain, physical activity, and compliance to multivitamin supplements.

Suboptimal Weight Loss 13 Years After Roux-en-Y Gastric Bypass: Is Hedonic Hunger, Eating Behaviour and Food Reward to Blame?

Purpose: Suboptimal weight loss (SWL) and weight regain (WR) following bariatric surgery are common. The exact reasons for this phenomenon remain to be fully elucidated. To compare hedonic hunger, food preferences, food reward and eating behaviour traits between participants with SWL and optimal weight loss (OWL) 13 years after Roux-en-Y gastric bypass (RYGB).

Iron Deficiency and Anemia 10 Years After Roux-en-Y Gastric Bypass for Severe Obesity.

Iron deficiency with or without anemia is a well-known long-term complication after Roux-en-Y, gastric bypass (RYGB) as the procedure alters the gastrointestinal absorption of iron. Iron is essential for hemoglobin synthesis and a number of cellular processes in muscles, neurons, and other organs. Ferritin is the best marker of iron status, and in a patient without inflammation, iron deficiency occurs when ferritin levels are below 15 µg/L, while iron insufficiency occurs when ferritin levels are below 50 µg/L.
