- BACKGROUND: The optimal sleeve diameter and distance from the pylorus to the edge of the resection line in laparoscopic sleeve gastrectomy (LSG) remain controversial.OBJECTIVES: To evaluate the influence of bougie size and antral resection distance from the pylorus on postoperative complications and weight-loss results in LSG.SETTING: Nationwide registry-based study.METHODS: This study included all LSGs performed in Sweden between 2012 and 2019. Data were obtained from the Scandinavian Obesity Surgery Registry. Reference bougie size of 35-36 Fr and an antral resection distance of 5 cm from the pylorus were compared to narrower bougie size (30-32 Fr), shorter distances (1-4 cm), and extended distances (6-8 cm) from the pylorus in assessing postoperative complications and weight loss as the outcomes of LSG. RESULTS: The study included 9,360 patients with postoperative follow-up rates of 96%, 79%, and 50% at 30 days, 1 year, and 2 years, respectively. Narrow bougie and short antral resection distance from the pylorus were significantly associated with increased postoperative weight loss. Bougie size was not associated with increased early or late complications. However, short antral resection distance was associated with high risk of overall early complications [odds ratio: 1.46 (1.17-1.82, P = .001)], although no impact on late complications at 1 and 2 years was observed.CONCLUSIONS: Using a narrow bougie and initiating resection closer to the pylorus were associated with greater maximum weight loss. Although a closer resection to the pylorus was associated with an increased risk of early postoperative complications, no association was observed with the use of narrow bougie for LSG.

- Background: Roux-en-Y gastric bypass is the most common procedure for revisional bariatric surgery. This study is an analysis of revisional gastric bypass operations (rGBP) compared with primary gastric bypass (pGBP) performed in Sweden between 2007 and 2016.Objective: The aim was to compare the incidence of adverse events in primary and revisional gastric bypass surgery and to identify predictive factors of intraoperative, early, and late complications in revisional gastric bypass surgery.Setting: Forty-four hospitals.Methods: Registered study from the Scandinavian Obesity Surgery Registry. The study group (rGBP) comprised 1795 patients, and the control group (pGBP) comprised 46,055 patients.Results: Median follow-up time was 28 months. The rate of open procedures was significantly higher in the rGBP group (39.1% versus 2.4%; P < .001) decreasing from 70.8% in 2007 to 8.5% in 2016. Intraoperative complications (15.5% versus 3.0%, P < .001), early complications (24.6% versus 8.7%; P < .001), and late complications (17.7% versus 8.7%; P < .001) occurred more often in the rGBP group. Open access in revisional surgery was an independent risk factor for intraoperative complications (odds ratio 3.87; 95% confidence interval: 2.69-5.57, P < .001), early complications (odds ratio 2.08; 95% confidence interval: 1.53-2.83, P < .001), and late complications (odds ratio 1.91; 95% confidence interval: 1.31-2.78, P = .001). Indication for revision or type of index operation were not associated with complications.Conclusion: RGBP was associated with a higher incidence of intraoperative, early, and late complications compared with pGBP. Open access in revisional surgery was predictive of complications regardless of the index operation or indication for revision.

- Background: In Sweden, Roux-en-Y gastric bypass is the most common procedure when revising a previous bariatric procedure. This study is an analysis of all revisional gastric bypass operations (rGBP) compared with a matched group of primary gastric bypass (pGBP) operated between 2007 and 2012.Objective: The aim was to determine whether improvement of obesity-related co-morbidity and changes in weight after revisional gastric bypass surgery were comparable with those seen after primary surgery.Setting: 44 hospitals in SwedenMethods: Retrospective data were retrieved from the Scandinavian Obesity Surgery Registry. The study group (rGBP) comprised 1224 patients, and the control group (pGBP) comprised 3612 patients matched for age and gender.Results: The indication for revision was weight failure in 512 patients (42%), a late complication of the initial procedure in 330 patients (27%), and a combination of weight failure and complication in 303 patients (25%). A total of 66% of patients in the rGBP group and 67% in the pGBP group completed the 2-year follow-up in the Scandinavian Obesity Surgery Registry.The rGBP-group had significantly less excess BMI loss (%EBMIL, 59.4 +/- 147.0 versus 79.5 +/- 24.7, P < .001) and a lower dyslipidemia remission rate (42.9% versus 62.0%, P = .005) at the time of the 2-year follow-up. Remission rates of sleep apnea, hypertension, type 2 diabetes, and depression were similar. The effects on obesity-related co-morbidity were not related to the indication for revisional surgery or the initial bariatric procedure.Conclusion: Even if weight results might be inferior compared with primary bypass procedures, the improvement of co-morbidity is similar.

- Background: Roux-en-Y gastric bypass (RYGB) among adolescents with obesity results in signif-icant weight loss; however, depot-specific changes have been understudied.Objective: We hypothesized that visceral adipose tissue (VAT) reduction in adolescents undergoing RYGB would be greater than other depots and associated with improvement in cardiometabolic risk factors.Setting: Three specialized treatment centers in Sweden. Methods: Fifty-nine adolescents underwent dual x-ray absorptiometry before surgery and at 1, 2, and 5 years after RYGB. Changes in body composition in multiple depots (total fat, lean body, gynoid fat, android fat, subcutaneous adipose tissue, and VAT) and cardiometabolic risk factors were assessed using multiple linear regression analysis and generalized estimating equations adjusting for age, sex, and baseline risk factor levels. Data are presented as percent change (95% CI) with regression models showing slopes and estimated P values.Results: At 1 year post-RYGB, a significant reduction was observed across all body composition measures (P , .001) with the greatest reduction observed in VAT (-65.1% [-68.7, -61.8]). From year 1 to 5 years post-RYGB, a regain was observed in all depots except lean body mass (1.2% [.3, 2.7], P 5 .105). A sex-specific difference in overall trajectories was only observed in lean body mass with males consistently having higher mean levels. Change in VAT at 1 year correlated with change in triglycerides (slope: .21 mg/dL/kg, P = .034) and fasting plasma insulin (slope: 44 pmol/L/kg, P = .027). Conclusions: Adiposity measures all decreased after RYGB but poorly predicted change in cardio-metabolic risk. Despite significant reductions at 1 year, a steady regain was observed out to 5 years, with values still well below baseline. Further research should consider control group comparison and extended follow-up.

- There is a lack of knowledge about the patient's experience of excess skin after bariatric surgery in patients with body mass index, (BMI)>50 kg/m(2). The objective of this study was to evaluate experience of excess skin after laparoscopic biliopancreatic diversion with duodenal switch (BPD/DS) or laparoscopic Roux-en-Y gastric bypass (LRYGB) and explore possible gender differences. Another aim was to analyze possible correlation between the reported experiences of excess skin with changes in weight, BMI, and hip and waist circumference after surgery.

- Background: Despite the modest effects of behavioral treatment on obesity in adolescence, bariatric surgery is rarely performed. Obesity often persists from childhood to adulthood, but it is not known how many individuals proceed with bariatric surgery in young adulthood. Objective: The aim of this study was to determine what proportion of individuals who received pediatric behavioral obesity treatment subsequently underwent bariatric surgery in early adulthood, and to identify predictors thereof. Setting: National registries, Sweden. Methods: In this prospective cohort study, the Swedish Childhood Obesity Treatment Register was linked to several national registers. Results: The childhood obesity cohort included 6502 (45% females) with a median age at follow-up of 21.7 years (interquartile range [IQR] 5.2). Of these, 8.2% underwent bariatric surgery at a median age of 20.9 years (IQR 4.2). The estimated cumulative incidence of bariatric surgery at age 30 was 21.5%. Obesity-related co-morbidities were identified in 31.7% before bariatric surgery in the childhood obesity cohort. Predictors of bariatric surgery were female sex, high body mass index standard deviation score (BMI SDS) at the start and end of treatment, poor treatment response, as well as own or parental cardiometabolic disease. Conclusions: More than a fifth are estimated to undergo bariatric surgery in early adulthood, despite having received pediatric behavioral obesity treatment. Our results indicate that for many children, behavioral treatment is insufficient in reducing obesity and preventing obesity-related co-morbidity. Therefore, it is reasonable to assume that more effective treatment of adolescents with severe obesity, including more rigorous behavioral support and pharmacologic treatment, but also more frequent use of bariatric surgery, would benefit this group of patients. © 2020 American Society for Bariatric Surgery

- BACKGROUND: Several studies have addressed short-term admission rates after bariatric surgery. However, studies on long-term admission rates are few and population based studies are even scarcer.OBJECTIVE: The aim of this study was to assess short- and long-term admission rates for gastrointestinal surgery after gastric bypass in Sweden compared with admission rates in the general population.SETTING: Swedish healthcare system.METHODS: The surgery cohort consisted of adults with body mass index≥35 identified in the Scandinavian Obesity Surgery Registry (n = 28,331; mean age 41 years; 76% women; Roux-en-Y gastric bypass performed 2007-2012). For each individual, up to 10 comparators from the general population were matched on birth year, sex, and place of residence (n = 274,513). The primary outcome was inpatient admissions due to gastrointestinal surgery retrieved from the National Patient Register through December 31, 2014. Conditional hazard ratios (HR) were estimated using Cox regression.RESULTS: All-cause admission rates were 6.5%, 21.4%, and 65.9% during 30 days, 1 year, and 6 years after surgery, respectively. The corresponding rates for gastrointestinal surgery were 1.8%, 6.8%, and 24.4%. Compared with that of the general population, there was an increased risk of all-cause hospital admission at 1 year (HR 2.6 [2.5-2.6]) and 6 years (HR 2.7 [2.6-2.7]). The risk of hospital admission for any gastrointestinal surgical procedure was greatly increased throughout the study period (HR 8.6 [8.4-8.9]). Female sex, psychiatric disease, and low education were risk factors.CONCLUSION: We found a significant risk of admission to hospital over>6 years after gastric bypass surgery.

Tidskriftsartikel (refereegranskat)abstract
- Background: The interaction between motivation to eat, eating behavior traits, and gut peptides after Roux-en-Y gastric bypass (RYGB) surgery is not fully understood. Methods: Appetite and hormone responses to a fixed liquid preload were assessed in 12 obese (body mass index 45 +/- 1.9 kg/m(2)) participants immediately before and 3 days, 2 months, and 1 year after RYGB surgery. Subjective appetite and plasma levels of ghrelin, leptin, insulin, and glucagon-like peptide-1 (GLP-1) were measured for a 3-hour postprandial period. Eating behavior traits were also measured using the Three Factor Eating Questionnaire 18 (TFEQR18). Results: There was a decrease in TFEQR18 emotional eating (EE) and uncontrolled eating (UE) from presurgery to 1 year postsurgery but no significant change in cognitive restraint (CR). These changes occurred independently of change in weight. In addition, there was a reduction in subjective appetite ratings and alterations in appetite peptides favoring an anorectic response. Presurgery EE was significantly related to fasting and area under the curve (AUC) ghrelin; UE was associated with AUC desire to eat, and there was a significant association between fasting desire to eat and ghrelin (fasting and AUC). One year postsurgery, UE was positively related to fasting insulin, and CR was negatively associated with GLP-1. UE and subjective hunger were positively correlated, while the relationship between desire to eat and ghrelin remained. onclusion: The relationships among subjective appetite ratings, eating behavior traits, and appetite peptides in obese patients both before and at 1 year after RYGB surgery may contribute to the reduction in a propensity to overeat (as measured by TFEQR18 factors) and weight loss.

- Background: Young adults display particularly poor weight loss in behavioral obesity treatment; nonetheless, they have seldom been included in bariatric research. Objectives: To compare weight loss, adverse events, and loss to follow-up in young (18-25 yr) versus older (>= 26 yr) adults up to 5 years after Roux-en-Y gastric bypass. Methods: Prospective registry data (Scandinavian Obesity Surgery Register) were analyzed in young (22.2 yr [standard deviation (SD): 2.1], 81.6% women, mean body mass index 43.7 kg/m(2) [SD: 5.4]) and older (42.6 years [SD: 9.6], 82.0% women, mean body mass index 43.4 kg/m(2) [SD: 5.0]) adults undergoing Roux-en-Y gastric bypass. Groups were matched for body mass index, sex, and year of surgery. Regression analyses and mixed models were used to compare outcomes between groups. Results: A total of 369 young (37.0% of eligible) and 2210 older (46.1%) adults attended the 5-year follow-up. At this time, weight loss was 31.8% in young and 28.2% in older adults (P < .001), with a serious adverse event (Clavien-Dindo >= 3b) being reported in 52 (14.1%) young and 153 (6.9%) older adults (odds ratio = 2.06, 95% confidence interval: 1.45-2.92, P < .001). Loss to follow-up was higher in young versus older adults throughout the study period (range of relative risk = 1.16-1.89, P < .001). Conclusions: While young adults displayed at least equal weight loss as older adults, rates of adverse events were approximately doubled, and loss to follow-up rates were higher. Future studies on the significance of and the etiology behind the higher incidence of serious adverse events are needed. Intensified clinical contact post Roux-en-Y gastric bypass should have the potential to further improve outcomes in young adults. (C) 2018 American Society for Bariatric Surgery.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Open Roux-en-Y gastric bypass (RYGB) may be chosen because of known widespread adhesions or as a result of conversion during laparoscopic surgery. Although conversions are rare, they occur even in experienced hands. The gastrojejunostomy may be performed with a circular stapler (CS) or a linear stapler (LS) or may be entirely hand sewn (HS). Our aim was to study differences in outcomes regarding the anastomotic techniques utilized in open surgery.SETTING: Nationwide cohort.METHODS: Data on open surgery, both primary open and converted procedures from Scandinavian Obesity Surgery Registry were analyzed for the years 2007-2013. Outcomes were assessed through multivariate analysis, adjusting for gender, age, preoperative body mass index, diabetes, conversion, and technique used for the gastrojejunostomy.RESULTS: CS was the most common method used for primary open RYGB (58%), whereas LS was the most common for converted RYGB (63%). HS was uncommon in both groups. Operative time was shorter for LS than for CS in the primary open RYGB (110±40 min versus 132±46 min; P<.001). Anastomotic leakage rates were similar in primary open RYGB (1.0%-2.4%), but leakage rates for LS in converted procedures was 10.1%, thus higher compared with 2.1% in converted CS patients (P = .02). Odds ratio for leakage was 2.87 (95% confidence interval 1.18-6.97) for LS using CS as a reference when adjusting for variables above.CONCLUSION: LS was associated to increased risk of leakage in patients with conversion from laparoscopic RYGB to open RYGB. Conversion to open surgery was associated to increased risk of leakage. Technique used for the gastrojejunostomy did not affect weight loss.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND:Weight loss before laparoscopic Roux-en-Y gastric bypass (LRYGB) is desirable, because it can reduce liver volume and thereby facilitate the procedure. The optimal duration of a low-calorie diet (LCD) has not been established. The objective of this study was to assess changes in liver volume and body composition during 4 weeks of LCD.METHODS:Ten women (aged 43±8.9 years, 114±12.1 kg, and body mass index 42±2.6 kg/m2) were examined on days 0, 3, 7, 14, and 28 after commencing the LCD. At each evaluation, body composition was assessed through bioelectric impedance analysis, and liver volume and intrahepatic fat content were assessed by magnetic resonance imaging. Serum and urine samples were obtained. Questionnaires regarding quality of life and LCD-related symptoms were administered.RESULTS:In total, mean weight decreased by 7.4±1.2 kg (range 5.7-9.1 kg), and 71% of the weight loss consisted of fat mass according to bioelectric impedance analysis. From day 0 to day 3, the weight loss (2.0 kg) consisted mainly of water. Liver volume decreased by 18%±6.2%, from 2.1 to 1.7 liters (P<.01), during the first 2 weeks with no further change thereafter. A continuous 51%±16% decrease was seen in intrahepatic fat content. Systolic blood pressure, insulin, and lipids improved, while liver enzymes, glucose levels, and quality of life were unaffected.CONCLUSION:A significant decrease in liver volume (18%) occurred during the first 2 weeks of LCD treatment, and intrahepatic fat gradually decreased throughout the study period. A preoperative 2-week LCD treatment seems sufficient in similar patients.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Although laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common bariatric procedure worldwide, no consensus on the optimal technique for the gastrojejunostomy (GJ) has been reached. Circular stapling (CS) immediately results in a GJ of standardized width, whereas linear stapling (LS) requires a technically challenging closure of the stapler defect. The aim was to study differences in outcomes between CS and LS.SETTING: Nationwide Swedish cohort.METHODS: The Scandinavian Obesity Registry (SOReg) included prospective data from 34,284 primary LRYGB patients operated on in 2007-2013. We studied operative time, length of hospital stay, postoperative complications, and percent excess body mass index loss (%EBMIL) after 1 year. Outcomes were assessed through multivariate analysis adjusting for gender, age, preoperative body mass index (BMI), and diabetes.RESULTS: Preoperatively the groups were similar (40.9 yr, BMI 42.4 kg/m(2), 76% female). For CS and LS, operative time and hospital stay were 114 and 73 minutes (P<.001) and 4.6 and 2.0 days (P<.001), respectively. Using LS as a reference, adjusted odds ratio (OR) for CS patients to have anastomotic leakage was 2.8 (95% CI 1.5-5.0), postoperative hemorrhage 1.9 (95% CI 1.2-2.9), wound complication 9.7 (95% CI 6.8-13.9), and marginal ulcer 3.1 (95% CI 1.8-5.3). The %EBMIL at 1 year was 80% for both techniques and 31% of total weight was lost. Follow-up rate at 6 weeks and 1 year was 96% and 73%, respectively.CONCLUSION: CS was found to be associated with disadvantages regarding operative time, hospital stay, and postoperative complications compared with LS.

Tidskriftsartikel (refereegranskat)abstract
- Background: Roux-en-Y gastric bypass (RYGB) is the most common bariatric procedure worldwide. There are few studies investigating how early return to solid food affects complications.Objective: The aim of this study was to explore how oral intake was resumed in RYGB patients and how the postoperative food regimen affects outcomes, such as complications and length of stay. Setting: Retrospective nationwide registry study.Methods: The Scandinavian Obesity Surgery Registry included prospective data from RYGB patients operated in 2009 to 2014. A questionnaire assessed the postoperative reintroduction of solid food applied at each bariatric center. The postoperative regimen was established in 23,589 patients. Outcomes were recorded at 30-day follow-up according to the standard Scandinavian Obesity Surgery Registry routine.Results: Nine percent of patients (n = 2074) returned to solid food within the first week after surgery. Most commonly solid food was resumed in week 4 (37%, n=8659). Median length of stay was 2 days for all. Of all, 2.8% suffered from a severe complication (>Clavien-Dindo 3a). After adjusting for the annual volume of procedures at hospitals, there was no correlation that the timing of solid food affected complication rates. The odds ratio for a severe complication was significantly lower for intermediate- (odds ratio .64 95% confidence interval .48.85) or high (odds ratio .52 95% confidence interval .42.66) volume centers. The rate of leaks and small bowel obstructions were evenly distributed between the different postoperative food regimens.Conclusion: Early return to solid food after RYGB did not affect the risk of severe complications. Patients operated at centers with an annual volume of > 100 procedures have a lower risk of severe complications. (C) 2018 American Society for Bariatric Surgery.

Tidskriftsartikel (refereegranskat)abstract
- Background: Roux-en-Y gastric bypass surgery (RYGB) as treatment of morbid obesity results in substantial weight loss. Most published long-term studies have included few patients at the last follow-up point. The aim of the present study was to explore long-term results in a large cohort of patients 7-17 years after gastric bypass.Methods: All 539 patients who had undergone primary RYGB from 1993 to 2003 at Uppsala and Orebro University Hospitals received a questionnaire regarding their postoperative status. Blood samples were obtained and the medical charts studied.Results: Of the 539 patients, 384 responded (71.2% response rate, mean age 37.9 yr, body mass index 44.5 kg/m(2) at surgery, 317 women, and 67 men). At a mean follow-up of 11.4 years (range 7-17), the body mass index had decreased to 32.5 kg/m(2), corresponding to an excess body mass index loss of 63.3%. Similar weight loss was observed, regardless of the length of follow-up. Orally treated diabetes resolved in 72% and sleep apnea and hyperlipidemia were improved. Revisional bariatric surgery had been performed in 2.1% and abdominoplasty in 40.2%. The gastrointestinal symptoms were considered tolerable. The overall result was satisfactory for 79% of the patients and 92% would recommend Roux-en-Y gastric bypass to a friend. Attendance to the annual checkups was 37%. Vitamin B-12 supplements were taken by 72% and multivitamins by 24%.Conclusion: At 11 years, substantial weight loss was maintained and revisional surgery was rare. Surprisingly few patients were compliant with the recommendation of lifelong supplements and yearly evaluations; however, patient satisfaction was high.

- Background: Gastric banding (GB) and vertical banded gastroplasty (VBG) may result in unsatisfactory weight loss or intolerable side effects. Such outcomes are potential indications for additional bariatric surgery, and Roux-en-Y gastric bypass is frequently used at such revisions (rRYGB). The present study examined long-term results of rRYGB.Methods: In total, 175 patients who had undergone rRYGB between 1993 and 2003 at 2 university hospitals received a questionnaire regarding their current status. The questionnaire was returned by 131 patients (75% follow-up rate, 66 VBG and 65 GB patients). Blood samples were obtained and medical charts studied. The reason for conversion was mainly unsatisfactory weight loss among the VBG patients and intolerable side effects among GB patients.Results: The 131 patients (112 women), mean age 41.8 years at rRYGB, were evaluated at mean 11.9 years (range 7-17) after rRYGB. Mean body mass index of those with prior unsatisfactory weight loss was reduced from 40.1 kg/m(2) (range 28.7-52.2) to 32.6 kg/m(2) (range 19.1-50.2) (P < .01). Only 2 patients (2%) underwent additional bariatric surgery after rRYGB. The overall result was satisfactory for 74% of the patients. Only 21% of the patients adhered to the recommendation of lifelong multivitamin supplements while 76% took vitamin B-12. Anemia was present in 18%.Conclusions: rRYGB results in sustained weight loss and satisfied patients when VBG or GB have failed. Subsequent bariatric surgery was rare but micronutrient deficiencies were frequent.

- BACKGROUND: Roux-en-Y gastric bypass (RYGB) is one of the most common bariatric procedures. Internal herniation may lead to small bowel ischemia requiring small bowel resection, resulting in short bowel syndrome. OBJECTIVE: To determine the incidence of extensive small bowel resection in patients operated with RYGB. We also aimed to look for early clinical warning signs among patients requiring extensive small bowel resection.SETTING: Cohort from national quality registers.METHODS: All patients having undergone RYGB between January 2007 to June 2019 were analyzed in the Scandinavian Obesity Surgery Registry (SOReg). We identified patients with small bowel obstruction (SBO) for whom small bowel resection was necessary. Additionally, we assessed clinical signs in these patients.RESULTS: The study included 57,255 patients having undergone RYGB. Closure of the mesenteric openings was performed in 78%. Surgery for SBO was required in 3659 (6%) of patients, and small bowel resection in 188 (.3%). Extensive small bowel resection, resulting in less than 1.5 meters of remaining small bowel, was required in 7 patients (.01%). All patients with extensive small bowel resection presented with abdominal pain and had confirmed internal herniation as the cause of the small bowel resection, and 2 of 7 patients died. Closure of mesenteric defects was not associated with a reduction in overall small bowel resection rates (P = .89)CONCLUSION: Surgery for SBO after RYGB was common (6%). The risk of extensive small bowel resection leading to short bowel was low (.01%). Patients with abdominal pain after RYGB should be assessed for internal hernia, as it can be devastating.

- Excess skin is well known after massive weight loss but, there is missing knowledge from various groups.To describe and compare excess skin in a reference population during obesity, after obesity surgery, and after reconstructive abdominoplasty.University hospital, Sweden.The following 6 groups were included: the reference population, obese adults before obesity surgery, obese adults after obesity surgery, adolescents after obesity surgery, super-obese adults after obesity surgery, and adults after abdominoplasty. All groups filled in the Sahlgrenska Excess Skin Questionnaire (SESQ). Some groups also underwent measurements of ptosis/excess skin on 4 body parts.All groups scored significantly higher experience of and discomfort from excess skin compared with the reference population. SESQ scores were significantly higher for obese adults (10.5 ± 8.5) and even higher for adults and adolescents (12.3 ± 8.1 versus 14.4 ± 7.7) after obesity surgery compared with the reference population (1.5 ± 3.5). Abdominoplasty resulted in significantly reduced scores (2.9 ± 5.2). Those undergoing obesity surgery and weight loss had significantly less excess skin measured on arms, breasts, and abdomen compared with before surgery, except for the upper arms on the adolescents. Excess skin increased on inner thighs in both age groups after weight loss. Correlations between objectively measured ptosis/excess skin and the patients' experience of and discomfort were .16 to .71, and the highest correlations were found among adolescents.Excess skin is not a problem for the vast majority of the normal population but is linked to obesity and massive weight loss. The SESQ score illustrates major problems related to excess skin both for obese adults and after obesity surgery for adults and for adolescents, who have problems similar to or worse than adults. Abdominoplasty markedly decreases symptoms.

- The majority of postbariatric patients experience major problems from excess skin, with most desiring abdominoplasty.To present visual assessments and objective measurements of excess abdominal skin; analyze relationships between patient-reported outcomes, objective measurements of excess skin, and visual assessments; and discuss criteria for reconstructive abdominal surgery in public healthcare.An academic hospital in Sweden.This is a secondary analysis of a prospective, longitudinal study that included 200 obese patients undergoing bariatric surgery, with 147 of these patients participating in follow-up 18-months postsurgery. Patients rated their symptoms related to excess skin and quality of life (QoL) according to the Sahlgrenska Excess Skin Questionnaire and EuroQol-5 D before and after bariatric surgery. Abdominal ptosis was measured at different anatomic locations.Waist circumference and ptosis were significantly reduced at all anatomic locations after weight loss, and abdominal ptosis was significantly larger laterally than at the midline (P < .001). The majority of patients had a ptosis ≥3 cm following bariatric surgery and had significantly more symptoms related to excess skin relative to those reported preoperation (P < .05). Additionally, the number of patients experiencing discomfort from excess skin increased along with increased ptosis size, but the correlation between ptosis size and QoL was low. Reconstructive abdominal surgery was requested by 70% of patients, all having significantly larger ptosis and significantly more symptoms than those not desiring surgery.Criteria for abdominal reconstruction should be based on both patient-reported symptoms and objective measures to ensure more patient-centered care than is possible only using objective measurements.

- Background: Laparoscopic sleeve gastrectomy (SG) achieves type 2 diabetes (T2D) remission to various extents, and reasons for such variations are unknown. Objectives: We assessed patients’ characteristics associated with T2D remission 1 year post SG. Setting: University hospital. Methods: Retrospective study of 230 T2D patients (18–64 yr) who underwent SG at our institution. We examined pre- and postoperative demographic, anthropometric, biochemical, and clinical characteristics associated with T2D complete remission, partial remission, improvement, or unchanged status. Independent predictors of T2D complete remission were assessed by binary logistic regression and then included in 7 predictive models. Logistic regression assessed the pre- and postoperative predictors of T2D complete remission and their predictive performance was measured with the area under the curve of the receiver operating characteristic curve. Results: A total of 230 patients were included in the study, females comprised 69%, and mean age was 45.66 ± 8.84 years. Mean preoperative weight and body mass index were 115.69 ± 20.76 kg and 43.53 ± 6.98 kg/m2, respectively. Approximately two thirds (64.4%) of the sample had diabetes for >5 years. Insulin therapy users comprised 36.9% of the sample and 29.6% of patients were on ≥2 oral hypoglycemic agents (OHA). At 1 year, mean body mass index was 32.77 ± 6.09 kg/m2, percent excess weight loss (%EWL) was 62.29 ± 23.60% and glycosylated hemoglobin (HbA1C) improved from 8.1% to 6.18%. Approximately 42.2% of the sample achieved T2D complete remission. Compared with those with no remission, patients with complete remission were significantly younger, had shorter duration of diabetes, were not on insulin therapy, took fewer OHA, had higher C-peptide, lower preoperative HbA1C, were less likely to have had hypertension or dyslipidemia, and more likely to have achieved higher %EWL. Seven proposed models for prediction of complete remission showed the most useful model comprised diabetes duration + pre-HbA1C + %EWL + insulin therapy + age + OHA (area under the curve = .81). Independent predictors of complete remission were preoperative HbA1C, %EWL, insulin therapy, age, and OHA (but not diabetes duration). Conclusion: SG results in significant weight reduction and various extents of T2D remission. HbA1C, %EWL, insulin therapy, age, and OHA were independent predictors of complete remission. Assessing these factors before bariatric surgery is important to identify any modifiable characteristics that can be altered to increase the likelihood of remission. © 2020 American Society for Bariatric Surgery
