- The aim was to investigate whether young children with drug-refractory nausea and vomiting can be treated with gastric electrical stimulation (GES) in a similar way as adults and to evaluate whether temporary percutaneous gastric electrical stimulation (TPGES) can be used in the pediatric population to select the patients who are responders to GES treatment. We report the clinical results in 3 children between 2 and 3 years of age. To the best of our knowledge, these are the youngest patients treated with GES.

- Background:Little is known about eating behaviour and meal pattern subsequent to Roux-en-Y gastric bypass (RYGB), knowledge important for the nutritional care process. The objective of the study was to obtain basic information of how meal size, eating rate, meal frequency and eating behaviour change upon the RYGB surgery.Materials and methods:Voluntary chosen meal size and eating rate were measured in a longitudinal, within subject, cohort study of 43 patients, 31 women and 12 men, age 42.6 (s.d. 9.7) years, body mass index (BMI) 44.5 (4.9) kgm(-2). Thirty-one non-obese subjects, 37.8 (13.6) years, BMI 23.7 (2.7) kgm(-2) served as a reference group. All subjects completed a meal pattern questionnaire and the Three-Factor Eating Questionnaire (TFEQ-R21).Results:Six weeks postoperatively meal size was 42% of the preoperative meal size, (P<0.001). After 1 and 2 years, meal size increased but was still lower than preoperative size 57% (P<0.001) and 66% (P<0.001), respectively. Mean meal duration was constant before and after surgery. Mean eating rate measured as amount consumed food per minute was 45% of preoperative eating rate 6 weeks postoperatively (P<0.001). After 1 and 2 years, eating rate increased to 65% (P<0.001) and 72% (P<0.001), respectively, of preoperative rate. Number of meals per day increased from 4.9 (95% confidence interval, 4.4,5.4) preoperatively to 6 weeks: 5.2 (4.9,5.6), (not significant), 1 year 5.8 (5.5,6.1), (P=0.003), and 2 years 5.4 (5.1,5.7), (not significant). Emotional and uncontrolled eating were significantly decreased postoperatively, (both P<0.001 at all-time points), while cognitive restraint was only transiently increased 6 weeks postoperatively (P=0.011).Conclusions:Subsequent to RYGB, patients display markedly changed eating behaviour and meal patterns, which may lead to sustained weight loss.International Journal of Obesity advance online publication, 29 November 2011; doi:10.1038/ijo.2011.217.

- OBJECTIVE: To identify risk factors for serious and specific early complications of laparoscopic gastric bypass surgery using a large national cohort of patients.BACKGROUND: Bariatric procedures are among the most common surgical procedures today. There is, however, still a need to identify preoperative and intraoperative risk factors for serious complications.METHODS: From the Scandinavian Obesity Surgery Registry database, we identified 26,173 patients undergoing primary laparoscopic gastric bypass operation for morbid obesity between May 1, 2007, and September 30, 2012. Follow-up on day 30 was 95.7%. Preoperative data and data from the operation were analyzed against serious postoperative complications and specific complications.RESULTS: The overall risk of serious postoperative complications was 3.4%. Age (adjusted P = 0.028), other additional operation [odds ratio (OR) = 1.50; confidence interval (CI): 1.04-2.18], intraoperative adverse event (OR = 2.63; 1.89-3.66), and conversion to open surgery (OR = 4.12; CI: 2.47-6.89) were all risk factors for serious postoperative complications. Annual hospital volume affected the rate of serious postoperative complications. If the hospital was in a learning curve at the time of the operation, the risk for serious postoperative complications was higher (OR = 1.45; CI: 1.22-1.71). The 90-day mortality rate was 0.04%.CONCLUSIONS: Intraoperative adverse events and conversion to open surgery are the strongest risk factors for serious complications after laparoscopic gastric bypass surgery. Annual operative volume and total institutional experience are important for the outcome. Patient related factors, in particular age, also increased the risk but to a lesser extent.

- Objective Increased sensitivity to alcohol after gastric bypass has been described. The aim of this study was to investigate whether bariatric surgery is associated with alcohol problems. Design and Methods The prospective, controlled Swedish Obese Subjects (SOS) study enrolled 2,010 obese patients who underwent bariatric surgery (68% vertical banded gastroplasty (VBG), 19% banding, and 13% gastric bypass) and 2,037 matched controls. Patients were recruited between 1987 and 2001. Data on alcohol abuse diagnoses, self-reported alcohol consumption, and alcohol problems were obtained from the National Patient Register and questionnaires. Follow-up time was 8-22 years. Results During follow-up, 93.1% of the surgery patients and 96.0% of the controls reported alcohol consumption classified as low risk by the World Health Organization (WHO). However, compared to controls, the gastric bypass group had increased risk of alcohol abuse diagnoses (adjusted hazard ratio [adjHR] = 4.97), alcohol consumption at least at the WHO medium risk level (adjHR = 2.69), and alcohol problems (adjHR = 5.91). VBG increased the risk of these conditions with adjHRs of 2.23, 1.52, and 2.30, respectively, while banding was not different from controls. Conclusions Alcohol consumption, alcohol problems, and alcohol abuse are increased after gastric bypass and VBG.

- OBJECTIVES: Improvement of gastric accommodation has been proposed as a potential explanation for the positive effect of gastric electrical stimulation (GES) on nausea/vomiting. A drinking test has been suggested as a noninvasive measure of gastric accommodation capacity. METHODS: Eight patients with therapy refractory nausea and vomiting and nonapproved diagnosis for GES (chronic intestinal pseudo-obstruction (CIP, n=1), functional dyspepsia (FD, n=3), postsurgical gastroparesis (PSGP, n=4) underwent temporary percutaneous GES for 10-14 days, randomized to stimulation ON or OFF, respectively. 19 patients [CIP (n=1), diabetic gastroparesis (n=5), FD (n=5), idiopathic gastroparesis (n=4), PSGP (n=4)] received permanent GES (Enterra, Medtronic) (follow-up at baseline, 6 and 12 months). At the end of each stimulation period a slow caloric satiety drinking test was performed (Nutridrink 1.5 kcal/ml, 15 ml/min). RESULTS: Healthy volunteers had higher drinking capacity compared to patients at baseline (1630+/-496 kcal vs. 887+/-412; P<0.001) and less composite symptom score (128+/-51 vs. 235+/-83; P<0.001). With temporary percutaneous GES, there was no significant change in drinking capacity during stimulation ON versus OFF (746+/-383 vs. 734+/-427 kcal) and symptom severity at the drinking test was unchanged. For patients having permanent GES there was no significant difference at 6 months (876+/-277 kcal) versus baseline, and no difference between symptomatic responders and nonresponders in change in drinking capacity (P=0.7). CONCLUSION: GES had no effect on proximal gastric function as evaluated by the slow caloric satiety drinking test. This seems to be the case for patients with approved as well as nonapproved indications for GES, and irrespective of the symptomatic response.
