RESUMO
BACKGROUND: Recent data support the use of bariatric surgery in adolescents with severe obesity following unsuccessful non-surgical treatments. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) have demonstrated reasonably similar weight loss and reduction of obesity related comorbidities in randomized trials in adults. SG has internationally become the most commonly used procedure in adolescents, yet long-term outcome data are lacking. No randomized controlled trial comparing SG and RYGB has been performed in adolescents. OBJECTIVE: Determine whether SG is non-inferior to RYGB in terms of total body weight (TBW) loss in adolescents with severe obesity. METHODS: A multicenter randomized controlled non-inferiority trial. Two hundred sixty-four adolescents aged 13-17 (Tanner stage ≥IV) with severe obesity (corrected for age and sex) will be included. Adolescents agreeing to participate will be randomized to either RYGB or SG. The primary outcome is the proportion of participants achieving 20% TBW loss at 3 years postoperatively. Secondary outcomes include (i) change in body weight, body mass index (BMI) and BMI standard deviation score, (ii) incidence of adverse health events and need for additional surgical intervention, (iii) resolution of obesity-related comorbidities, (iv) prevalence of cardio metabolic risk factor measures, (v) bone health measures and incidence of bone fractures, (vi) quality of life including psychosocial health, patient satisfaction and educational attainment and (vii) body composition. Follow-up will extend into the long term. RESULTS: Not applicable. DISCUSSION: This study will, to our knowledge, be the first randomized controlled trial comparing SG and RYGB in adolescents with severe obesity. TRIAL REGISTRATION: The trial is registered at the Netherlands Trial Register on July 26th, 2018 - NTR7191 - https://www.trialregister.nl/trial/7191 (protocol version 5.0 - February 3th 2020).

Background: Weight loss failure or weight regain occurs in up to 25% of patients with a Roux-en-Y gastric bypass (RYGB). Post-operative anatomical changes, like pouch or stoma dilatation, might contribute. Aim of this study is to assess reliability and usefulness of upper gastro intestinal (UGI) contrast studies to detect pouch dilatation.Methods: Retrospective case-control study of patients with weight loss failure between 2010 and 2015 (failure group, n = 101) and a control group (n = 101) with adequate weight loss. Pouch dilatation was systematically reassessed. Clinical parameters were extracted from the electronic patient records.Results: Systematic reassessment showed 23/101 (23%) pouch dilatation in the failure group, compared to 11/101 (11%) in the control group (p = .024). Revision surgery was performed in 43/101 patients in the failure group. After this surgery, only 8% of patients with pouch dilatation achieved adequate weight loss, whereas 39% of patients without pouch dilatation achieved adequate weight loss (p = .07). There was no difference in return to adequate weight loss between patients treated surgically and conservatively (30% vs 28%).Conclusion: Systematic reassessment of UGI contrast studies showed 23% pouch dilatation in patients with weight loss failure after RYGB. However, low interobserver agreement and discrepancy in success rate of revision surgery greatly questions the reliability and usefulness of this diagnostic modality.

An 89-year-old female came to the Emergency Department in acute respiratory distress and septic shock caused by a right-sided intra-thoracic incarcerated necrotic ileum. An idiopathic right-sided diaphragmatic herniation is rare. The herniation presumably occurred due to an old defect or weakness of the right-sided diaphragm post-traumatically.

Background: Bariatric complications may occur during pregnancy, potentially causing serious maternal and fetal problems. The aim of this study was to determine the current practice and preferences of bariatric surgeons regarding the pregnancy care of fertile women before and after bariatric surgery. Methods: A 26-question anonymous online survey was designed and sent to all bariatric surgeons of the Dutch Society of Metabolic and Bariatric Surgery. Results: At least one bariatric surgeon from each bariatric center (n = 18) completed the survey. In case of a future child, wish sleeve gastrectomy became more popular than Roux-en-Y gastric bypass. All surgeons provided preoperative education regarding bariatric complications during pregnancy. Nine centers without neonatal intensive care would not refer pregnant women with acute complications. Half of the centers had a standard operating procedure. Seven per 18 bariatric centers had seen at least one postbariatric pregnant patient with severe maternal morbidity. One case of perinatal mortality was reported. Conclusion: There is an inconsistent and often below guideline standard daily practice regarding pregnancy before and after bariatric surgery. There is limited experience with pregnant women with acute bariatric complications. Referral to tertiary centers is inadequate. Better information provision for both professionals and patients regarding possible complications is needed.
RESUMO
BACKGROUND: The most commonly performed bariatric procedures worldwide are Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), yet outcomes following these procedures in young adults are limited. Therefore, the objective of this study was to compare weight loss outcomes between RYGB and SG in young adults. METHODS: This is a nationwide retrospective cohort study of young adults, aged 18-25 years, who underwent RYGB or SG between 2015 and 2019, with data from the Dutch Audit Treatment of Obesity (DATO). The primary outcome was weight loss expressed as percentage total weight loss (%TWL) in a period of 3 years after surgery. Secondary outcomes were the incidence of complications (< 30 days) and progression of obesity-related comorbidities. RESULTS: In total, 2313 patients were included, 1246 in the RYGB group and 1067 in the SG group. Percentage TWL was significantly higher in the RYGB group compared to the SG group at 1, 2, and 3 years after surgery (respectively 2.4%, 2.9%, and 3.3% higher, p < 0.001). RYGB was associated with an on-average 2.75 higher %TWL compared to SG in females (p < 0.001), although this was not seen in males (ß = 0.63, p = 0.514). No differences were found in the incidence of complications, nor the progression of obesity-related comorbidities except for gastroesophageal reflux disease (GERD). There was more improvement or resolution of GERD in the RYGB group (95.2% vs. 56.3%, p < 0.001). CONCLUSION: Similar numbers of RYGB and SG were performed in young adults, whereas RYGB was associated with greater weight loss in the short- and midterm, particularly in females.

BACKGROUND: When performing a Roux-en-Y gastric bypass (RYGB), the gastroenterostomy can be constructed with a circular stapled or linear stapled technique. The size of the gastroenterostomy depends on the stapling method and this may affect weight loss outcomes. The aim of this study was to examine the impact of the stapling technique on weight loss outcomes after RYGB. METHODS: This is a nationwide population-based cohort study of patients that received a RYGB. Data were derived from the Dutch Audit of Treatment of Obesity. Primary outcome was the impact of stapling technique on the rate of non-response defined as significant weight regain (≥20% of a patients' lost weight) 2-4 years post-surgery, after initial successful weight loss (≥20% total weight loss, TWL). Secondary outcomes were the rate of response, defined as successful weight loss (≥20% TWL) within 1.5 years post-surgery, the incidence of complications and the progression of comorbidities. RESULTS: In a cohort of 12,468 patients, non-response was equally distributed between both groups (circular 18.0% vs. linear 17.6%). No differences in response rate (circular 97.0% vs. linear 96.5%) or %TWL were observed up to 4 years post-surgery. Patients in the circular stapled group experienced more complications, specifically major bleedings (2.4% vs. 1.2%; p=0.002) within 30 days postoperatively. No differences were found in deteriorated comorbidities, neither in de novo developed comorbidities. CONCLUSION: When comparing stapling technique in RYGB, weight loss outcomes did not differ during a 4-year follow-up period. The linear stapled gastroenterostomy could pose an advantage due to its lower complication rate.

PURPOSE: Primary nonresponse (1NR) - inability to achieve adequate weight loss after surgery - and secondary nonresponse (2NR) - excessive weight regain after initial adequate weight loss after surgery - can occur in up to 25-35% of patients after bariatric surgery. The aim of this study was to explore the variations in both definition as well as management of 1NR and 2NR amongst bariatric surgeons. MATERIALS AND METHODS: An online survey was distributed to all members of the national bariatric societies in the Netherlands and Belgium regarding questions about definition, work-up and treatment of 1NR and 2NR after bariatric surgery. RESULTS: A total of 45 responses from bariatric surgeons were obtained, representing 32 medical centers that perform bariatric procedures. When assessing 1NR, excess weight loss(EWL) was reported to be used by most respondents(30/45), total body weight loss(TBWL) by 18/45 and body mass index(BMI) by 25/45. A great variation in cut off values was observed. When assessing 2NR, percentage weight gain from the lowest (nadir) weight was preferred most by 22/45 respondents with cut off values varying from 5 to 20%. Most respondents deemed 18 months after initial surgery the most appropriate timeframe to determine 1NR or 2NR. CONCLUSIONS: The current practice regarding primary and secondary nonresponse after bariatric surgery has a wide variety in definitions, work-up and treatment options. Consensus on the definition of 1NR and 2NR is needed to optimize the treatment of bariatric patients.

BACKGROUND: Pregnant women with a history of bariatric surgery (BS) may develop acute abdominal pain related to this surgery, especially after Roux-en-Y gastric bypass. Studies showed alarming results regarding maternal and foetal morbidity and mortality. The aim of this study was to analyse these outcomes for pregnant women and their offspring. METHODS: Single-centre retrospective cohort study in a tertiary referral centre for bariatric complications during pregnancy. Pregnant women with a history of BS referred between September 2015 and November 2019 with acute abdominal pain suspected for a bariatric complication were included. Data were retrospectively collected from the patient files, and a questionnaire was sent regarding the postoperative course and childbirth. RESULTS: Fifty women were included. At presentation, mean maternal age was 31 (± 4) years, and median gestational age was 28+4 (25+4, 30+5) weeks. Thirteen women were treated conservatively. Thirty-seven women underwent surgery for, among others, internal herniation (n = 26) and intussusception (n = 6). Six women required small bowel resection. Two women underwent an emergency caesarean section shortly after the surgery due to foetal distress. Eight women delivered preterm of whom five infants required respiratory support. There was one intrauterine foetal death. Surgery > 48 h after the onset of the symptoms was not associated with an increase in small bowel resections or preterm birth. CONCLUSION: Acute abdominal pain in pregnant women may be related to a bariatric complication. Further awareness of bariatric complications within the obstetric care and transferal to specialized care to prevent diagnostic delay may improve maternal and neonatal outcome.

Lack of standard definitions of primary and secondary (non)responders after RYGB and SG makes it impossible to compare the literature. The aim was to analyze the different definitions used. MEDLINE® was searched for literature published between 01-07-2014 and 01-07-2017 concerning (1) patients who received a primary RYGB or SG and (2) the outcomes of primary and secondary (non)responders. One hundred twelve out of 650 papers were eligible. Forty out of 47 papers described a definition of weight loss success. Sixty-seven out of 112 papers mentioned weight loss failure of which 42 described a definition, in total 23 different definitions. Weight regain was mentioned in 77 papers; only 21 papers provided a definition. The recent literature regarding definitions of these outcomes is highly inconsistent. To compare the literature international consensus is required.
