Obesity surgery

Bariatric surgery was established at several Norwegian hospitals in 2004. This study evaluates the perioperative outcome and the learning curves for two surgeons while introducing laparoscopic Roux-en-Y gastric bypass (LRYGB). ⋯ LRYGB was introduced with an acceptable morbidity rate and no mortality. Only the length of surgery and postoperative hospital stay were suitable indicators of a learning curve, which comprised about 100 cases.

A super-obese patient who suffered from severe sleep apnea (SSA) and other comorbidities underwent insertion of a BioEnterics intragastric balloon (BIB) before bariatric surgery. During the night, he was victim of cardiac arrest. After cardiopulmonary resuscitation and return of spontaneous circulation, he was transferred to intensive care unit. ⋯ The BIB induces vagal nerve activation by stretching the gastric wall. In addition, super-obese patients with sleep apnea and other comorbitities have an increased risk of potentially fatal cardiac arrhythmias especially during the night. For all these reasons, we think that these patients may benefit from further preoperative cardiac investigations and a more intensive control during the first postinsertion day.

Case Reports
Retrograde endoscopic cystgastrostomy for pancreatic pseudocyst drainage after a Prior Roux-en-Y gastric bypass.
A 47-year-old woman with a history of Roux-en-Y gastric bypass developed a pancreatic pseudocyst after an episode of acute necrotizing pancreatitis. She presented with intractable abdominal pain and weight loss. ⋯ The patient underwent exploratory laparotomy, at which a Whipple procedure was aborted due to severe fibrosis and necrosis of her pancreas. Retrograde peroral endoscopic pancreatic pseudocyst drainage was successfully performed through the defunctionalized stomach.

Obesity has emerged as one of the most serious public health concerns in the twenty-first century. the fat mass and obesity associated gene (FTO) has been found to contribute to the risk of obesity in humans. Our aims in this study were to investigate the association of rs9939609 single nucleotide polymorphism (SNP) of the FTO gene with different obesity-related parameters, to assess the FTO gene expression in subcutaneous and visceral adipose tissues from morbidly obese and its correlations with other adipocytokine gene expressions. ⋯ Our results show: (1) A strong association between rs9939609 SNP of the FTO gene variant and obesity in Spanish morbidly obese adult patients; (2) positive correlations between FTO mRNA and leptin, perilipin, and visfatin gene expressions in subcutaneous adipose tissue; (3) FTO and perilipin gene expressions were positively correlated in visceral fat depot. Overall these results may suggest a role of FTO in the regulation of lipolysis as well as in total body fat rather in fat distribution patterns.

Evidence for the necessity to systematically assess micronutrient status prior to bariatric surgery.
Bariatric surgery has been proven the most effective treatment of morbid obesity, but micronutrient deficiency following bariatric surgery is a major concern. Increasing evidence points to a generally poor micronutrient status in obese subjects. ⋯ Data indicate a high prevalence of micronutrient deficiencies in morbidly obese subjects. Based on these results, we strongly recommend a systematic assessment of the micronutrient status in all candidates for bariatric surgery.
