Biliopancreatic Diversion for Severe Obesity: Long-Term Effectiveness and Nutritional Complications.
Bariatric surgery is currently the treatment of choice for those patients with severe obesity, but the procedure of choice is not clearly established. We describe weight loss and nutritional parameters in severely obese patients after biliopancreatic diversion for 10 years of follow-up. ⋯ Biliopancreatic diversion is an effective surgical procedure in terms of weight loss, quality of life, and evolution of obesity-related diseases. Nutritional deficiencies are less frequent than feared for a malabsorptive procedure, but must be taken into account, especially for fat-soluble vitamins.

The effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) is controversial. Although concomitant hiatal hernia repair (HHR) at the time of LSG is common and advocated by many, there are few data on the outcomes of GERD symptoms in these patients. The aim of this study was to evaluate the effect of concomitant HHR on GERD symptoms in morbidly obese patients undergoing LSG. ⋯ Based on our data, LSG with concomitant HHR improved GERD symptoms or the need for daily antisecretory therapy only in a third of symptomatic patients. Furthermore, 15.6 % of asymptomatic patients developed de novo GERD symptoms despite a HHR. In patients with a documented hiatal hernia, HHR does not lead to GERD resolution or prevention after LSG, indicating the need for appropriate patient counseling and further study.

Fatigue and mental workload are directly associated with high-complexity tasks. In general, difficult tasks produce a higher mental workload, leaving little opportunity to deal with new/unexpected events and increasing the likelihood of performance errors. The laparoscopic Roux-en-Y gastric bypass (LRYGB) learning curve is considered to be one of the most difficult to complete in laparoscopic surgery. We wished to validate the National Aeronautics and Space Administration Task Load Index (NASA-TLX) in LRYGB and identify factors that could provoke a higher mental workload for surgeons during the learning curve. ⋯ The NASA-TLX is a valid tool to gauge mental workload in LRYGB.

The proportion of population older than 60 years is rapidly increasing. The majority of this older population suffers from multiple comorbid conditions including obesity. Non-surgical means of weight loss do not offer a predictable solution. Surgical interventions seem to be the most promising solution for the obesity problem, but there is a relative lack of data in literature regarding bariatric procedures in older populations. ⋯ Bariatric surgery can be safe and effective for patients older than 60 years of age with a low morbidity and mortality; the weight loss and improvement in comorbidities in older patients were clinically significant. When compared to the general population, there was no statistically significant difference in the average %EWL at 12 months or the number of complications due to surgery. Long-term effects of such interventions will need further studies and investigations.

Laparoscopic procedures for the treatment of morbid obesity are commonly offered to patients with comorbidities previously thought to carry prohibitive operative risk. In this study, we reviewed characteristics and perioperative outcomes of patients with dialysis-dependent renal failure (DDRF) who underwent laparoscopic bariatric procedures. ⋯ When performed in selected DDRF patients, bariatric surgery is safe. An increase in LSG with a concurrent decline in LAGB procedures was demonstrated over the period of the study.
