Change in gastrointestinal symptoms over the first 5?years after bariatric surgery in a multicenter cohort of adolescents.

ABSTRACT: BACKGROUND:Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) are effective for weight loss in adolescents with severe obesity. However, little is known about adverse gastrointestinal symptoms (GIS) following these operations in adolescents. The objective was to examine GIS over 5?years after surgery and differences by surgery type. METHODS:We prospectively studied 228 adolescents (161 RYGB, 67 VSG) undergoing bariatric surgery. Gastrointestinal symptoms were assessed before surgery, at 6-months, and yearly to 5?years after surgery. Symptom severity was dichotomized for analysis. Analysis of post-surgery symptoms involved linear models adjusting for baseline symptoms, BMI, early post-operative complication, sex, and race. RESULTS:Participants at surgery were 17?±?1.6?years with preoperative BMI 53?±?9.4?kg/m2. From 6?months to 5?years, gastroesophageal reflux symptoms (GERS), nausea, bloating, and diarrhea increased. Crude prevalence rates of GERS increased from 4% (1% RYGB, 11% VSG) at 6-months post-surgery to 14% (10% RYGB, 26% VSG) at 5-years. In adjusted analyses, the VSG group experienced 4-fold (4.85 95% CI 2.63, 8.91, p?

Project description:BackgroundPatients having bariatric surgery have lower mortality compared with those with similar body mass index who do not undergo surgery. It is unclear whether mortality post-bariatric surgery is similar to the general population. The benefit of bariatric surgery would be highlighted should people previously at high risk for premature death have comparable, or better, mortality as the general population.ObjectiveTo compare mortality after bariatric surgery to the general U.S. population of the same age, sex, and race.SettingThe Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) prospective cohort of 2458 adults who underwent bariatric surgery at 10 U.S. hospitals between 2006 and 2009.MethodsDeaths were identified via LABS-2 follow-up and the National Death Index. Standardized mortality ratios (SMR) of post-bariatric surgery mortality observed in LABS-2 versus age-, sex-, race-, and year-adjusted expected mortality in the general U.S. population were calculated and compared with 1, which results when the number of observed and expected deaths are equal.ResultsLABS-2 median follow-up was 6.6 (interquartile range: 5.9-7.0) years postsurgery. Seventy-six deaths were observed over 15,616 person-years (PY) of observation (4.9 deaths/1000 PY). The rate expected in the general U.S. population with the same age, sex, race, and year distribution was 4.8 deaths per 1000 PY (SMR = 1.02, 95% confidence interval [CI]: .80-1.27). There were no significant differences between observed and expected mortality by surgical procedure. Compared with expected mortality in the general U.S. population, people 35-44 years old at time of surgery had significantly more deaths (SMR = 2.06, 95% CI: 1.22-3.25), while people at least 55 years of age had significantly fewer (SMR = .63, 95% CI: .42-.92). Significantly more deaths than expected occurred in the perioperative period and 5-7 years after surgery.ConclusionsMortality within 7 years of bariatric surgery is comparable to the general U.S. population, which is likely to have better survival than people with severe obesity. However, more deaths than expected were identified 5-7 years after surgery.

Project description:BackgroundThe expansion of the obesity epidemic is accompanied with an increase in bariatric procedures, in particular in women of reproductive age. The weight loss induced by the surgery is believed to reverse the negative impact of overweight and obesity on female reproduction, however, research is limited to in particular retrospective cohort studies and a growing number of small case-series and case-(control) studies.Methods/designAURORA is a multicenter prospective cohort study. The main objective is to collect long-term data on reproductive outcomes before and after bariatric surgery and in a subsequent pregnancy. Women aged 18-45 years are invited to participate at 4 possible inclusion moments: 1) before surgery, 2) after surgery, 3) before 15 weeks of pregnancy and 4) in the immediate postpartum period (day 3-4). Depending on the time of inclusion, data are collected before surgery (T1), 3 weeks and 3, 6, 12 or x months after surgery (T2-T5) and during the first, second and third trimester of pregnancy (T6-T8), at delivery (T9) and 6 weeks and 6 months after delivery (T10-T11). Online questionnaires are send on the different measuring moments. Data are collected on contraception, menstrual cycle, sexuality, intention of becoming pregnant, diet, physical activity, lifestyle, psycho-social characteristics and dietary supplement intake. Fasting blood samples determine levels of vitamin A, D, E, K, B-1, B-12 and folate, albumin, total protein, coagulation parameters, magnesium, calcium, zinc and glucose. Participants are weighted every measuring moment. Fetal ultrasounds and pregnancy course and complications are reported every trimester of pregnancy. Breastfeeding is recorded and breast milk composition in the postpartum period is studied.DiscussionAURORA is a multicenter prospective cohort study extensively monitoring women before undergoing bariatric surgery until a subsequent pregnancy and postpartum period.Trial registrationRetrospectively registered (July 2015 - NCT02515214 ).
