    Abstract: Pregnant women who previously had bariatric surgery may develop acute abdominal pain during pregnancy. Two patients, 38-year-old twin primigravida (gestational age of 24+6 weeks) and a 26-year-old woman (gestational age of 24+0 weeks), both of whom had ... ...

    Abstract Pregnant women who previously had bariatric surgery may develop acute abdominal pain during pregnancy. Two patients, 38-year-old twin primigravida (gestational age of 24+6 weeks) and a 26-year-old woman (gestational age of 24+0 weeks), both of whom had laparoscopic gastric bypass surgery previously, developed abdominal pain. The patients both had diffuse abdominal pain in combination with normal blood tests and imaging. Patient B had undergone laparoscopy at another centre after 5 weeks of gestation for internal herniation. After referral to our multidisciplinary bariatric-obstetric-neonatal (MD-BON) team, diagnostic laparoscopy was advised as internal herniation was deemed possible. In both patients, internal herniation was indeed found in Petersen's space and jejunal mesenteric defect, which was closed using laparoscopic surgery. Both women delivered healthy offspring afterwards. The presence of an MD-BON team allows for an increased awareness of potential long-term complications associated with earlier bariatric surgery in pregnancy.

    Abstract 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.

    Abstract Background: Roux-en-Y gastric bypass (RYGB) is associated with approximately 25 % weight loss failure, resulting in insufficient weight loss or weight regain. Strategies of revisional surgery focus on alteration of limb length, pouch or stoma size. Altering pouch size and outlet by adding laparoscopic adjustable gastric band (LAGB) might initiate further weight loss. The goal of this study is to review the safety and efficacy of LAGB after failed RYGB in a retrospective cohort of patients in our institute.
    Methods: Patients with secondary LAGB (n = 44) were studied between May 2012 and January 2015. Demographics, effects on weight loss and complications were analysed.
    Results: Mean age and body mass index (BMI) at time of LAGB was 45.8 ± 8.2 years and 37.2 ± 5.4 kg/m
    Conclusion: In this largest published cohort, secondary banding of failed RYGB provides only limited additional weight loss. Furthermore, this technique is associated with high morbidity and reoperation rates. A significant difference in effect was found between patients with weight loss failure and weight regain. Larger prospective series are necessary to evaluate if the modest benefits are worth the risks of secondary LAGB.

    Abstract 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.

    Title translation Abdominal pain in a pregnant patient who had gastric reduction surgery: risks associated with a history of bariatric surgery.
    Abstract Pregnant women who previously had bariatric surgery may develop acute abdominal pain during pregnancy that may be related to previous operations. Two patients, a 38-year-old twin-primigravida who had a gestation period of 24+6 weeks and a 26-year-old woman who had a gestation period of 24 weeks, both of whom had laparoscopic gastric bypass (RYGB) surgery 2 and 3 years previously, developed abdominal pain. The patients were not ill, but had diffuse abdominal pain in combination with normal blood tests and imaging. Patient B had undergone laparoscopy at another centre after 5 weeks of gestation for internal herniation. After referral to our multidisciplinary Bariatric-Obstetric-Neonatal (MD-BON) team, diagnostic laparoscopy was advised as internal herniation was deemed possible. In both patients, internal herniation was indeed found in Petersen's space and jejunal mesenteric defect, which was closed using laparoscopic surgery.
