- OBJECTIVE: To compare opioid use in patients with obesity treated with bariatric surgery versus adults with obesity who underwent intensive lifestyle modification. SUMMARY OFBACKGROUND DATA: Previous studies of opioid use after bariatric surgery have been limited by small sample sizes, short follow-up, and lack of control groups.METHODS: Nationwide matched cohort study including individuals from the Scandinavian Obesity Surgery Registry and the Itrim health database with individuals undergoing structured intensive lifestyle modification, between August 1, 2007 and September 30, 2015. Participants were matched on Body Mass Index, age, sex, education, previous opioid use, diabetes, cardiovascular disease, and psychiatric status (n = 30,359:21,356). Dispensed opioids were retrieved from the Swedish Prescribed Drug Register from 2 years before to up to 8 years after intervention.RESULTS: During the 2-year period before treatment, prevalence of individuals receiving ≥1 opioid prescription was identical in the surgery and lifestyle group. At 3 years, the prevalence of opioid prescriptions was 14.7% versus 8.9% in the surgery and lifestyle groups (mean difference 5.9%, 95% confidence interval 5.3-6.4) and at 8 years 16.9% versus 9.0% (7.9%, 6.8-9.0). The difference in mean daily dose also increased over time and was 3.55 mg in the surgery group versus 1.17 mg in the lifestyle group at 8 years (mean difference [adjusted for baseline dose] 2.30 mg, 95% confidence interval 1.61-2.98).CONCLUSIONS: Bariatric surgery was associated with a higher proportion of opioid users and larger total opioid dose, compared to actively treated obese individuals. These trends were especially evident in patients who received additional surgery during follow-up.

- Background: Laparoscopic sleeve gastrectomy (LSG) as a primary bariatric procedure has gained increasing popularity world-wide. However, controversies still exist regarding several operative aspects, such as the optimal diameter of thesleeve and the optimal distance from the pylorus to the edge of the resection line, and whether these aspects haveeffects on weight-loss results and the risk to develop postoperative complications.Objective: The aim of this study was to compare weight-loss results and the incidence of postoperative complications betweensleeve with different diameters measured in bougie size and with different distances from the pylorus to the edge ofthe resection line measured in centimeter.Setting: Nationwide registry-based study.Method: This study is an analysis of sleeve gastrectomy performed in Sweden between 2012 and 2019. Data were collectedfrom Scandinavian Obesity Surgery Registry (SOReg). Patients with bougie size 30-32 and 35-36 and patients withdistance from pylorus 1-4 cm, 5 cm, 6-8 cm were identified and compared regarding weight-loss results and the riskto develop postoperative complications.Results: 9,360 patients were included. Follow-up rate was 96% at day 30, 78.8% at one year and 50% at two years. Bothbougie size 30-32 compared to 35-36 and distance from the pylorus 1-4 cm compared to 5 cm were associated withsignificant higher weight-loss at one and two years. No difference in the risk for early or late complications was seenbetween bougie size groups 30-32 and 35-36. Resection starting 1-4 cm from the pylorus compared to 5 cm was as-sociated with higher risk for overall early postoperative complications (OR 1.46 (1.17-1.82, P=.001)), but there wasno significant difference in the risk to develop late complication at 1 and 2 years. No difference in the leak rate andin the risk to develop stricture was seen between different Bougie sizes, nor distances from the Pylorus.Conclusion: Using a smaller Bougie size and starting the resection closer to the pylorus was associated with better maximumweight-loss. Closer resection to the Pylorus, but not Bougie size was associated with increased risk for early postop-erative complications after sleeve gastrectomy.

- PURPOSE: Bariatric and metabolic surgery is an effective treatment for severe and complex obesity; however, robust long-term data comparing operations is lacking. Clinical registries complement clinical trials in contributing to this evidence base. Agreement on standard data for bariatric registries is needed to facilitate comparisons. This study developed a Core Registry Set (CRS) - core data to include in bariatric surgery registries globally.MATERIALS AND METHODS: Relevant items were identified from a bariatric surgery research core outcome set, a registry data dictionary project, systematic literature searches, and a patient advisory group. This comprehensive list informed a questionnaire for a two-round Delphi survey with international health professionals. Participants rated each item's importance and received anonymized feedback in round 2. Using pre-defined criteria, items were then categorized for voting at a consensus meeting to agree the CRS.RESULTS: Items identified from all sources were grouped into 97 questionnaire items. Professionals (n = 272) from 56 countries participated in the round 1 survey of which 45% responded to round 2. Twenty-four professionals from 13 countries participated in the consensus meeting. Twelve items were voted into the CRS including demographic and bariatric procedure information, effectiveness, and safety outcomes.CONCLUSION: This CRS is the first step towards unifying bariatric surgery registries internationally. We recommend the CRS is included as a minimum dataset in all bariatric registries worldwide. Adoption of the CRS will enable meaningful international comparisons of bariatric operations. Future work will agree definitions and measures for the CRS including incorporating quality-of-life measures defined in a parallel project.

Total knee arthroplasty and bariatric surgery : change in BMI and risk of revision depending on sequence of surgery
- 2023
-
Ingår i: BMC Surgery. - : BioMed Central (BMC). - 1471-2482. ; 23:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with obesity have a higher risk of complications after total knee arthroplasty (TKA). We investigated the change in weight 1 and 2 years post-Bariatric Surgery (BS) in patients that had undergone both TKA and BS as well as the risk of revision after TKA based on if BS was performed before or after the TKA.METHODS: Patients who had undergone BS within 2 years before or after TKA were identified from the Scandinavian Obesity Surgery Register (SOReg) and the Swedish Knee Arthroplasty Register (SKAR) between 2007 and 2019 and 2009 and 2020, respectively. The cohort was divided into two groups; patients who underwent TKA before BS (TKA-BS) and patients who underwent BS before TKA (BS-TKA). Multilinear regression analysis and a Cox proportional hazards model were used to analyze weight change after BS and the risk of revision after TKA.RESULTS: Of the 584 patients included in the study, 119 patients underwent TKA before BS and 465 underwent BS before TKA. No association was detected between the sequence of surgery and total weight loss 1 and 2 years post-BS, - 0.1 (95% confidence interval (CI), - 1.7 to 1.5) and - 1.2 (95% CI, - 5.2 to 2.9), or the risk of revision after TKA [hazard ratio 1.54 (95% CI 0.5-4.5)].CONCLUSION: The sequence of surgery in patients undergoing both BS and TKA does not appear to be associated with weight loss after BS or the risk of revision after TKA.

- BACKGROUND: Symptomatic postbariatric hypoglycemia (PBH) is a known complication that can occur a few years after Roux-en-Y gastric bypass (RYGB). There is currently no established rating scale for PBH-associated symptoms developed for use in Swedish populations. The aim of the study was to translate an already existing questionnaire into Swedish and to test its reliability.METHODS: The study included forward and backward translations of the original Dumping Severity Scale (DSS) questionnaire with 8 items regarding symptoms of early dumping and 6 items regarding hypoglycemia, with each item graded on a 4-point Likert scale. The reliability of the Swedish translated questionnaire (DSS-Swe) was estimated using internal consistency and test-retest methods.RESULTS: A total of 200 patients were included in the study. Good internal consistency was demonstrated regarding the items related to early dumping symptoms, with a Cronbach's alpha coefficient of 0.82, and very good agreement in terms of test-retest reliability, with an overall intraclass correlation coefficient (ICC) of 0.91 (95% CI 0.88-0.93). The items related to hypoglycemia yielded a good Cronbach's alpha coefficient of 0.76 and an ICC of 0.89 (95% CI 0.85-0.91).CONCLUSION: The DSS-Swe questionnaire shows good reliability regarding both internal consistency and test-retest performance for use in Swedish populations.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: It remains unknown whether routine division of the greater omentum during laparoscopic Roux-en-Y gastric bypass (LRYGB) influences the risk for small bowel obstruction (SBO) after RYGB.OBJECTIVE: To evaluate the effect of omental division on SBO after LRYGB stratified by handling of the mesenteric defects.SETTING: Nationwide, registry-based.METHODS: In this registry-based cohort study, 40,517 patients who underwent LRYGB in Sweden within the period from January 1, 2007, to December 31, 2019, with data from the Scandinavian Obesity Surgery Registry (SOReg) were included. The study was based on combined data from the SOReg, the National Patient Register, the Swedish Prescribed Drugs Register, and the Total Population Registry. The main outcome was reoperation for SBO.RESULTS: During a follow-up period of 5.9 ± 2.6 years, the cumulative incidence of SBO was 11.2% in the nondivision group compared with 9.7% among patients with divided omentum (hazard ratio [HR] = .83, 95% confidence interval [CI]: .77-.89, P < .001). The association was seen in patients without mesenteric defects closure (HR = .69, 95% CI: .61-.78, P < .001) as well as patients with closed mesenteric defects (HR = .80, 95% CI: .74-.87, P < .001).CONCLUSION: Division of the greater omentum is associated with reduced risk for SBO after antecolic, antegastric LRYGB and should be considered as a complement to mesenteric defects closure to further reduce the risk for SBO after LRYGB.

- Purpose Obesity is associated with increased incidence of kidney stones, a risk further increased by metabolic and bariatric surgery, particularly after procedures with a malabsorptive component. However, there is a paucity in reports on baseline risk factor and on larger population-based cohorts. The objective was to evaluate incidence and risk factors for kidney stones after bariatric surgery by comparing them to an age-, sex-, and geographically matched cohort from the normal population. Material and Methods Patients operated with primary Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), or biliopancreatic diversion with duodenal switch (BPD-DS) from 2007 until 2017 within the Scandinavian Obesity Surgery registry were matched 1:10 to controls from the normal population. Hospital admission or outpatient visits due to kidney stones registered in the National Patient Registry were considered as endpoint. Results The study included 58,366 surgical patients (mean age 41.0 +/-, BMI 42.0 +/- 5.68, 76% women) with median follow-up time 5.0 [IQR 2.9-7.0] years and 583,660 controls. All surgical procedures were associated with a significantly increased risk for kidney stones (RYGB, HR 6.16, [95% CI 5.37-7.06]; SG, HR 6.33, [95% CI 3.57-11.25]; BPD/DS, HR 10.16, [95% CI 2.94-35.09]). Higher age, type 2 diabetes hypertension at baseline, and a preoperative history of kidney stones were risk factors for having a postoperative diagnosis of kidney stones. Conclusion Primary RYGB, SG, and BPD/DS were all associated with a more than sixfold increased risk for postoperative kidney stones. The risk increased with advancing age, two common obesity-related conditions, and among patients with preoperative history of kidney stones.

- BACKGROUND: The personal economic impact of bariatric surgery is not well-described. OBJECTIVES: To examine earnings and work loss from 5 years before to 5 years after bariatric surgery compared with the general population.SETTING: Nationwide matched cohort study in the Swedish health care system.METHODS: Patients undergoing primary bariatric surgery (n = 15,828) and an equal number of comparators from the Swedish general population were identified and matched on age, sex, place of residence, and educational level. Annual taxable earnings (primary outcome) and annual work loss (secondary outcome combining months with sick leave and disability pension) were retrieved from Statistics Sweden. Participants were included in the analysis until the year of study end, emigration or death.RESULTS: From 5 years before to 5 years after bariatric surgery, earnings increased for patients overall and in subgroups defined by education level and sex, while work loss remained relatively constant. Bariatric patients and matched comparators from the general population increased their earnings in a near parallel fashion, from 5 years before (mean difference -$3,489 [95%CI -3,918 to -3,060]) to 5 years after surgery (-$4,164 [-4,709 to -3,619]). Work loss was relatively stable within both groups but with large absolute differences both at 5 years before (1.09 months, [95%CI 1.01 to 1.17]) and 5 years after surgery (1.25 months, [1.11 to 1.40]).CONCLUSIONS: Five years after treatment, bariatric surgery had not reduced the gap in earnings and work loss between surgery patients and matched comparators from the general population.

- IMPORTANCE: Short-term and midterm data suggest that mesenteric defects closure during laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery reduces the risk of internal herniation with small bowel obstruction (SBO) but may increase risk of kinking of the jejunojejunostomy in the early postoperative period. However, to our knowledge, there are no clinical trials reporting long-term results from this intervention in terms of risk for SBO or opioid use.OBJECTIVE: To evaluate long-term safety and efficacy outcomes of closure of mesenteric defects during LRYGB.DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial with a 2-arm, parallel, open-label design included patients with severe obesity scheduled for LRYGB bariatric surgery at 12 centers in Sweden from May 1, 2010, through November 14, 2011, with 10 years of follow-up after the intervention. INTERVENTIONS: During the operation, patients were randomly assigned 1:1 to closure of mesenteric defects beneath the jejunojejunostomy and at the Petersen space using nonabsorbable running sutures during LRYGB or to nonclosure.MAIN OUTCOME AND MEASURES: The primary outcome was reoperation for SBO. New incident, chronic opioid use was a secondary end point as a measure of harm.RESULTS: A total of 2507 patients (mean [SD] age, 41.7 [10.7] years; 1863 female [74.3%]) were randomly assigned to closure of mesenteric defects (n = 1259) or nonclosure (n = 1248). After censoring for death and emigration, 1193 patients in the closure group (94.8%) and 1198 in the nonclosure group (96.0%) were followed up until the study closed. Over a median follow-up of 10 years (IQR, 10.0-10.0 years), a reoperation for SBO from day 31 to 10 years after surgery was performed in 185 patients with nonclosure (10-year cumulative incidence, 14.9%; 95% CI, 13.0%-16.9%) and in 98 patients with closure (10-year cumulative incidence, 7.8%; 95% CI, 6.4%-9.4%) (subhazard ratio [SHR], 0.42; 95% CI, 0.32-0.55). New incident chronic opioid use was seen among 175 of 863 opioid-naive patients with nonclosure (10-year cumulative incidence, 20.4%; 95% CI, 17.7%-23.0%) and 166 of 895 opioid-naive patients with closure (10-year cumulative incidence, 18.7%; 95% CI, 16.2%-21.3%) (SHR, 0.90; 95% CI, 0.73-1.11).CONCLUSIONS AND RELEVANCE: This randomized clinical trial found long-term reduced risk of SBO after mesenteric defects closure in LRYGB. The findings suggest that routine use of this procedure during LRYGB should be considered.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01137201.
