Roux-en-Y gastric bypass is the most effective therapy for morbid obesity. This study investigated how gastric bypass affects intake of and preference for high-fat food in an experimental (rat) study and within a trial setting (human). Proportion of dietary fat in gastric bypass patients was significantly lower 6 yr after surgery compared with patients after vertical-banded gastroplasty (P = 0....

conclusions administration of gabapentin before surgery can reduce pain after lgbp. furthermore, it is not accompanied by significant short-term adverse effects. results the mean pain score in the group receiving gabapentin was significantly lower than the placebo group (p < 0.001). indications and dose of opioid consumption between the two groups were not statistically significant. incidence o...

conclusions in the newly set up center similar to the older one, surgical treatment in our follow up duration was effective for reducing weight, body mass index reduction and achievement of success in biochemical markers on diabetics. results during follow up time after 276 days mean weight decreased from 118.7 ± 23.3 to 82.9 ± 15.7, p < 0.001 bmi also changed from 45.2 ± 1.8 to 32.2 ± 1.3, p <...

background: prevalence of obesity in the world, in both developed and developing countries, is growing rapidly. bariatric surgery is now accepted as the treatment for morbid obesity. objective: this study compares laparoscopic sleeve gastrectomy's effectiveness (lsg) with the most common bariatric surgery, laparoscopic roux-en-y (lrygb) gastric bypass.   methods: a systematic review was perform...

BACKGROUND In recent years, a surgical technique known as single-anastomosis gastric bypass or mini-gastric bypass has been developed. Its frequency of performance has increased considerably in the current decade. AIM To describe the mini-gastric bypass technique, its implementation and preliminary results in a university hospital. M...

Gastric bypass patients are at risk for small-bowel obstruction secondary to adhesions, internal hernias, intussusception and volvulus. Most gastric bypass patients do not present with classic obstructive symptoms. We present a rare case of concurrent intussusception and volvulus in a woman with previous history of internal hernia following laparoscopic Roux-en-Y gastric bypass surgery.

Gastric bypass surgery, by definition, changes the absorption capabilities of the stomach and small intestine. The use of oral medications in patients post gastric bypass may need to be adjusted by medical providers to account for this absorption change. The following case exemplifies this dilemma in a pregnant patient status post gastric bypass surgery with a complicated urinary tract infection.

To evaluate the theoretical increased precision offered by utilization of the robotic instrument, we attempted to determine whether incorporation of its use into traditional laparoscopic gastric bypass would duplicate or improve the success of the operation without increasing complications. The Roux-en-Y gastric bypass is the most commonly performed procedure for morbid obesity in the United St...

Despite the many benefits of bariatric surgery in patients with morbid obesity, concerns have been raised over its association with severe hyperinsulinemic hypoglycemia and nesidioblastosis following Roux-en-Y gastric bypass surgery. Cases have been described with severe post-prandial hypoglycemia with neurological symptoms following surgery. Some of these cases are recalcitrant to medical trea...

Roux-en-Y gastric bypass surgery remains the major surgical option for individuals with medically complicated obesity. The importance of preoperative evaluation to permit identification of micronutrient deficiencies is being re-evaluated. The risk of complications related to pregnancy after gastric bypass supports careful follow-up. Micronutrient deficiencies are common in postoperative gastric...
