    Abstract Background: Surgical interventions, such as paraoesophageal hernia (POH) repair, are complex with multiple components that require consideration in the reporting of clinical trials. Many aspects of POH repair, including mesh hiatal reinforcement and fundoplication type, are contentious. This review summarizes the reporting of components and outcomes in RCTs of POH repair.
    Methods: Systematic searches identified RCTs of POH repair published from 1995 to 2020. The patient selection criteria for RCT involvement were noted. The components of the surgical interventions in these RCTs were recorded using the CONSORT guidelines for non-pharmacological treatments, Template for Intervention Description and Replication (TIDieR) and Blencowe frameworks. The outcomes were summarized and definitions sought for critical variables, including recurrence.
    Results: Of 1918 abstracts and 21 screened full-text articles, 12 full papers reporting on six RCTs were included in the review. The patient selection criteria and definitions of POH between trials varied considerably. Although some description of trial interventions was provided in all RCTs, this varied in depth and detail. Four RCTs described efforts to standardize the trial intervention. Outcomes were reported inconsistently, were rarely defined fully, and overall trial conclusions varied during follow-up.
    Conclusion: This lack of detail on the surgical intervention in POH repair RCTs prevents full understanding of what exact procedure was evaluated and how it should be delivered in clinical practice to gain the desired treatment effects. Improved focus on the definitions, descriptions and reporting of surgical interventions in POH repair is required for better future RCTs.

    Abstract Background: Roux-en-Y gastric bypass (RYGB) is a gold-standard procedure for treatment of obesity and associated comorbidities. No consensus on the optimal design of this operation has been achieved, with various lengths of bypassed small bowel limb lengths being used by bariatric surgeons. This aim of this systematic review and meta-analysis was to determine whether biliopancreatic limb (BPL) length in RYGB affects postoperative outcomes including superior reduction in weight, body mass index (BMI), and resolution of metabolic comorbidities associated with obesity.
    Methods: A systematic search of the literature was conducted up until 1st June 2021. Meta-analysis of primary outcomes was performed utilising a random-effects model. Statistical significance was determined by p value < 0.05.
    Results: Ten randomised controlled trials were included in the final quantitative analysis. No difference in outcomes following short versus long BLP in RYGB was identified at 12-72 months post-operatively, namely in BMI reduction, remission or improvement of type 2 diabetes mellitus, hypertension, dyslipidaemia, and complications (p > 0.05). Even though results of four studies showed superior total body weight loss in the long BPL cohorts at 24 months post-operatively (pooled mean difference -6.92, 95% CI -12.37, -1.48, p = 0.01), this outcome was not observed at any other timepoint.
    Conclusion: Based on the outcomes of the present study, there is no definitive evidence to suggest that alteration of the BPL affects the quantity of weight loss or resolution of co-existent metabolic comorbidities associated with obesity.

    Abstract The Heald Silastic Anal Stent (HSAS) was designed to protect a newly constructed low colorectal anastomosis by keeping the anus open for up to 10 days postoperatively, and has also been used in combination with percutaneous drainage to treat a leak from a low rectal anastomosis. We describe a technique in two patients where the HSAS alone allowed adequate drainage of a leaking low colorectal anastomosis.

    Abstract The study aimed at application of a high performance liquid chromatography (HPLC) with UV detector for selenium speciation in samples of mineral and well waters in Poland. Basic solutions 1000 microg/l SeO3(2-) and SeO4(2-) were prepared by dissolving 2.190 g of reagent Na2SeO3 and 2.393 g Na2SeO4 in 1000 ml of deionised water, respectively. Recent standards SeO3(2-) and SeO4(2-) (single or mixed) were prepared daily. Chromatographic separations were obtained on a column with reversed phase of C18, 250*4 mm, 5 microm ODS. As mobile phase mixture of 5 mmol/l phosphate tetrabutylammonium, 50/50 water/methanol at pH 3.4 was used. Flow rate of mobile phase was 1 ml/min and detector was set on lambda = 210 nm. Injection volumes were 5 microl. The average concentration of Se(IV) was 4.10 microg/l and Se(VI) - 4.27 microg/l and Se(II) - 0.54 microg/l although the differences between water samples originating from various sources were relatively high. The developed method can be therefore recommended for determination of Se in samples of mineral water.

    Abstract Context: Bariatric surgery has beneficial effects on obesity and associated comorbidities such as glycaemic control in type 2 diabetes, dyslipidaemia, hypertension, and renal and hepatic function. Nevertheless, this surgery is not free of complications and possible side effects due to restrictive and/or malabsorptive related components.
    Case description: We report the case of a 60-year-old woman whose past medical history included morbid obesity, hypertension and Scopinaro biliopancreatic diversion (BPD) with duodenal switch in 1998. In 2015, she attended the emergency department hypotensive with bad general condition and reporting chronic constitutional symptoms. A wide variety of tests were performed including endoscopic studies as her symptoms were not immediately correlated with the BPD surgery. Finally, she was diagnosed from gastrojejunal stricture which caused her severe malnutrition. The patient underwent successful surgical management.
    Discussion: BPD is one of the most effective surgical procedures for obesity, with an overall 5-year loss of excess body weight higher than 72%. Nonetheless, it is associated with long-term complications such as protein malnutrition and vitamin deficiencies due to malabsorption. Being surgically challenging, with high risk of nutritional complications and lifelong needed for the follow-up, BPD is rarely performed nowadays.
    Conclusions: Bariatric Surgery is a well-known effective therapeutic measure to improve obesity and cardiovascular related disease. However, this case highlights the importance of robust multidisciplinary lifelong surgical and medical follow-up in all BPD patients. BPD complications can be minimised and recognised early with patient and healthcare staff education on the importance of lifetime follow-up and adherence to dietary and supplement regimes.

    Abstract Background: Bariatric and metabolic surgery (BMS) is an established safe, effective, and durable treatment for obesity and its complications. However, there is still a paucity of evidence on surgery outcomes in patients suffering from extreme obesity.
    Objectives: This study aimed to evaluate outcomes of BMS in weight loss and the resolution of co-morbidities in patients with a body mass index (BMI) ≥70kg/m
    Setting: National Health Service and private hospitals in the United Kingdom.
    Methods: This cohort study analyzed prospectively collected records from the UK National Bariatric Surgery Registry of patients with a BMI ≥70 kg/m
    Results: There were 230 patients (64% female) eligible for inclusion in the study: 22 underwent AGB; 102 underwent SG, and 106 underwent RYGB. Preoperative weight and BMI values were comparable (76 ± 7 kg/m
    Conclusion: This study found that primary BMS in patients with a BMI >70kg/m

    Abstract Background: An excessively long-blind end of the alimentary limb following a Roux-en-Y gastric bypass (RYGB), known as a 'candy cane' (CC), may cause symptoms including abdominal pain, regurgitation and vomiting. Very few studies have examined the efficacy of surgical resection of the CC.
    Objectives: The aim of this study was to assess sensitivity of preoperative diagnostic tools for CC, as well as perioperative outcomes and symptom resolution after CC revision surgery.
    Setting: High volume bariatric centre of excellence, United Kingdom.
    Methods: Observational study of CC revisions from 2010 to 2017.
    Results: Twenty-eight CC revision cases were identified (mean age 45 ± 9 years, female preponderance 9:1). Presenting symptoms were abdominal pain (86%), regurgitation/vomiting (43%), suboptimal weight loss (36%) and acid reflux (21%). Preoperative tests provided correct diagnosis in 63% of barium contrast swallows, 50% of upper gastrointestinal endoscopies and 29% computed tomographies. Patients presenting with pain had significantly higher CC size as compared with pain-free group (4.2 vs. 2 cm, p = 0.001). Perioperative complications occurred in 25% of cases. Complete or partial symptom resolution was documented in 73% of patients undergoing CC revision. Highest success rates were recorded in the regurgitation/vomiting group (67%).
    Conclusion: Surgical revision of CC is associated with good symptom resolution in the majority of patients, especially those presenting with regurgitation/vomiting. However, it carries certain risk of complications. CC diagnosis may frequently be missed; hence more than one diagnostic tool should be considered when investigating symptomatic patients after RYGB.
