Health benefits and risks during 10 years after Roux-en-Y gastric bypass.

BACKGROUND: Long-term evaluations 10 years after Roux-en-Y gastric bypass (RYGB) are limited. We report the development in weight and cardiovascular risk factors during 10 years after laparoscopic RYGB, with evaluation of gastrointestinal symptoms and quality of life (QoL) at 10-year follow-up. METHODS: We performed a prospective longitudinal cohort study. Patients operated with laparoscopic RYGB from May 2004 to November 2006 were invited to 10-year follow-up consultations. Gastrointestinal Symptom Rating Scale (GSRS) questionnaire and two QoL questionnaires were used for analyses of gastrointestinal symptoms and QoL. RESULTS: A total of 203 patients were operated; nine (4.4%) died during follow-up. Of 194 eligible patients, 124 (63.9%) attended 10-year follow-up consultations. Percent excess weight loss (%EWL) and percent total weight loss (%TWL) at 10 years were 53.0% and 24.1%, respectively. %EWL > 50% was seen in 53.2%. Significant weight regain (≥15%) from 2 to 10 years was seen in 63.3%. Remission rates of type 2 diabetes, dyslipidemia, and hypertension were 56.8%, 46.0%, and 41.4%, respectively. Abdominal operations beyond 30 days after RYGB were reported in 33.9%. Internal hernia and ileus (13.7%) and gallstone-related disease (9.7%) were the most common causes. Vitamin D deficiency (<50nmol/L) was seen in 33.3%. At 10 years, bothersome abdominal pain and indigestion symptoms (GSRS scores ≥3) were reported in 42.9% and 54.0%, respectively, and were associated with low QoL. CONCLUSION: We observed significant weight loss and remission of comorbidities 10 years after RYGB. Significant weight regain occurred in a substantial subset of patients. Gastrointestinal symptoms were common and negatively impacted QoL.

Abdominal pain and symptoms before and after Roux-en-Y gastric bypass.

Background: Despite increased emphasis on patient-reported outcomes, few studies have focused on abdominal pain symptoms before and after Roux-en-Y gastric bypass (RYGB). The aim of this study was to quantify chronic abdominal pain (CAP) in relation to RYGB. Methods: Patients with morbid obesity planned for RYGB were invited to participate at a tertiary referral centre from February 2014 to June 2015. Participants completed a series of seven questionnaires before and 2 years after RYGB. CAP was defined as patient-reported presence of long-term or recurrent abdominal pain lasting for more than 3 months. Results: A total of 236 patients were included, of whom 209 (88·6 per cent) attended follow-up. CAP was reported by 28 patients (11·9 per cent) at baseline and 60 (28·7 per cent) at follow-up (P < 0·001). Gastrointestinal Symptom Rating Scale (GSRS) scores (except reflux scores) and symptoms of anxiety increased from baseline to follow-up. Most quality of life (QoL) scores (except role emotional, mental health and mental component scores) also increased. At follow-up, patients with CAP had higher GSRS scores than those without CAP, with large effect sizes for abdominal pain and indigestion syndrome scores. Patients with CAP had more symptoms of anxiety, higher levels of catastrophizing and lower QoL scores. Baseline CAP seemed to predict CAP at follow-up. Conclusion: The prevalence of CAP is higher 2 years after RYGB compared with baseline values.
