Pharmacologic pain treatment is common among bariatric patients. Nonsteroid anti-inflammatory drugs (NSAID) are not recommended after Roux-en-Y gastric bypass (RYGB) because of the increased risk of marginal ulceration, but the connection with NSAID is not unambiguous. Examine the association between NSAID exposure and peptic ulcers after primary laparoscopic RYGB and sleeve gastrectomy (SG) respectively. University Hospital, Sweden. Cross-matched data from 3 national registers were used in this retrospective, population-based cohort study of all primary laparoscopic RYGB and SG in Sweden within the period from 2010–2015. NSAID exposure was analyzed with individual data of dispensed daily defined doses (DDD) of NSAID after surgery. Multivariate logistic regression estimated the association between NSAID exposure and peptic ulcers, expressed as odds ratios with 95% confidence intervals adjusted for confounding. Of the 41,380 patients (37,913 RYGB, 3467 SG), 1.8% were diagnosed with peptic ulcers after surgery (RYGB 1.9%, SG.2%). In total, 60% of the patients had been prescribed NSAID during a follow-up period of 4.1 (1.0–7.0) years in median. The adjusted risk odds ratios for NSAID exposure were 1.10 (.88–1.38), 1.43 (1.16–1.76), and 1.52 (1.25–1.84) for >0–30 DDD, >30–100 DDD, and >100 DDD, respectively. In subanalysis, the association was similar for RYGB alone, whereas no association was found for SG. The results of the present study support the notion that continuous NSAID use of ≥30 days is a significant risk factor for the development of peptic ulcers after RYGB, whereas temporary use (<30 days) is not. No association between NSAID exposure and the development of peptic ulcers after SG was identified. [Display omitted] - NSAIDs are frequently prescribed to patients which has undergone bariatric surgery - The prevalence of peptic ulcers was 1.8% in this cohort of 41,380 patients - Continuous NSAID-use (>30 days) is a significant risk factor for peptic ulcers after RYGB - No increased risk was observed for temporary NSAID-use (<30 days) [ABSTRACT FROM AUTHOR]

The association between severe obesity and chronic pain makes opioid use common among bariatric patients. Preoperative opioid use has been identified as a risk factor in other surgical procedures. To examine the impact of preoperative opioid use on complications after primary bariatric surgery. Sweden. All primary laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) patients from 2007–2017 were identified in the Scandinavian Obesity Surgery Register. Prescriptions for opioids within 90 days prior to surgery were retrieved from the Swedish Prescribed Drug Register and converted into oral morphine equivalents (OMEs). Patients with ≥2 prescription of opioids within 90 days prior to surgery were defined as chronic opioid users. Generalized linear regression was used to adjust for age, sex, body mass index, procedure type, year of operation, and co-morbidities. Of the 56,183 patients who had undergone primary LRYGB (n = 49,615) or LSG (n = 6568), 17.5% (n = 9825) had at least 1 prescription of opioids prior to surgery, of which 4.3% (n = 2390) were defined as chronic opioid users. Chronic opioid use was associated with a higher risk of severe complications (Clavien Dindo grade ≥ 3b; odds ratio [OR], 1.67; 95% confidence interval [CI], 1.37–2.04), increased lengths of stay (relative risk, 1.11; 95% CI, 1.08–1.14), and higher rates of readmission (OR, 1.70; 95% CI, 1.49–1.94) and reoperation (OR, 1.87; 95% CI, 1.53–2.27; all P values <.001). Furthermore, higher OME exposure was associated with stepwise higher risks. Preoperative opioid use was an independent risk factor for severe complications, as well as prolonged lengths of stay, readmission, and reoperation after primary bariatric surgery. [Display omitted] - Chronic opioid use was associated with an increased risk of severe complications - Length of stay was prolonged - 30-day readmission and reoperation rates were increased - Increasing opioid exposure was associated with stepwise higher risks [ABSTRACT FROM AUTHOR]

Insufficient weight loss is common in super-obese patients (body mass index >50) after Roux-en-Y gastric bypass (RYGB). Duodenal switch (DS) is more effective; however, it is considered to have an increased complication rate. To compare early complications (≤30 d), long-term adverse events, and quality of life (QoL) between primary DS and RYGB. Sweden. National cohort-study of super-obese patients after primary DS or RYGB in Sweden 2007 to 2017. Propensity-score matching was used to reduce confounders. Five national registers were cross-matched. The study population consisted of 333 DS and 1332 RYGB (body mass index 55 ± 5 kg/m2, 38.5 ± 11 yr, and 60.7% females). Laparoscopic approach was used in 25% of DS and 91% of RYGB. Early complications were more common after DS (15.3% versus 8.1%, P <.01), mainly because of more open surgery and related surgical site infections. During 4.6 ± 2.3 years mean follow-up, hospital admission rate was 1.4 ± 2.3 versus 1.1 ± 3.3 (P =.18), with 6.7 ± 18.3 versus 7.0 ± 43.0 in-hospital days, for DS and RYGB, respectively. An increased risk of malnutrition/malabsorption requiring inpatient care (2.8% versus.2%, odds ratio 12.3 [3.3–45.7]) and greater need for additional abdominal surgery (25.8% versus 15.3%, odds ratio 2.0 [1.5–2.7]) was observed for DS. However, QoL was more improved after DS. DS was associated with more early complications because of more open surgery, but long-term requirement of inpatient care was similar to RYGB. The increased risk of malnutrition/malabsorption and need for additional abdominal surgeries was contrasted with a greater improvement in QoL for DS. [ABSTRACT FROM AUTHOR]

Unsatisfactory weight loss is common after bariatric surgery in patients with super obesity (body mass index [BMI] ≥50 kg/m2). Unfortunately, this group of patients is increasing worldwide. The aim of this study was to compare long-term weight loss and effect on co-morbidities after duodenal switch (DS) and gastric bypass (RYGB) in super-obese patients. University hospital, Sweden, national cohort. This observational population-based cohort-study of primary DS and RYGB (BMI ≥48 kg/m2) in Sweden from 2007 to 2017 used data from 4 national registers. Baseline characteristics were used for propensity score matching (1 DS:4 RYGB). Weight loss was analyzed up until 5 years after surgery. Medication for diabetes, hypertension, dyslipidemia, depression, and pain were analyzed up until 10 years after surgery. The study population consisted of 333 DS and 1332 RYGB, with 60.7% females averaging 38.5 years old and BMI 55.0 kg/m2 at baseline. DS resulted in a lower BMI at 5 years compared with RYGB, 32.2 ± 5.5 and 37.8 ± 7.3, respectively, (P <.01). DS reduced prevalence of diabetes and hypertension more than RYGB, while reduction in dyslipidemia was similar for both groups, during the 10-year follow-up. Both groups increased their use of antidepressants and a maintained a high use of opioids. This study indicates that super-obese patients have more favorable outcomes regarding weight loss and effect on diabetes and hypertension, after DS compared with RYGB. Propensity-score matched, national cohort of 333 DS and 1332 RYGB. DS resulted in a superior weight loss at 5 years. DS resulted in greater improvement in diabetes and hypertension, 10-year follow-up. [ABSTRACT FROM AUTHOR]
