More Anastomotic Ulcers, Less Dumping, and Equal Weight Loss in Long vs. Short Gastric Pouch in Laparoscopic Roux-en-Y Gastric Bypass.

Background: Anastomotic ulcers (AU) at the gastroenterostomy are a common postoperative complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). Possible risk factors for ulcer formation include active smoking, the use of non-steroidal anti-inflammatory drugs, increased tension or ischemia at the anastomosis, or factors that increase the acid secretion of the gastric pouch. Therefore, a longer gastric pouch may increase risk of AU formation after LRYGB.

Think-Aloud Testing of a Companion App for Colonoscopy Exams: Usability Study.

Background: Colonoscopies, are vital for initial screening, follow-ups, surveillance of neoplasia, and assessing symptoms like rectal bleeding. Successful colonoscopies require thorough colon preparation, but up to 25% fail due to poor preparation. This can lead to longer procedures, repeat colonoscopies, inconvenience, poorer health outcomes, and higher costs.

European recommendations from health care professionals and people living with obesity on safe practice for bariatric and metabolic surgery medical tourism: a modified delphi consensus statement from EASO, IFSO-EC and ECPO.

Background: Bariatric and metabolic surgery tourism (BMT) is becoming an increasingly popular route to treatment for patients living with obesity. Recent reports have highlighted that some patients travelling abroad for bariatric surgery have received inadequate care, fraudulent care, and, tragically, some cases have resulted in death. This study aimed to define consensus in Europe regarding safe practices concerning BMT.

Role of sleeve gastrectomy in improving metabolic syndrome: an overview.

Metabolic syndrome (MetS) presents a global health challenge characterized by cardiometabolic risk factors like central obesity, elevated blood pressure, dyslipidemia, and high fasting glucose levels. Despite lifestyle interventions and medications, the increasing prevalence of MetS calls for effective treatments. Sleeve gastrectomy (SG) has emerged as a promising intervention.

Competency, Proficiency, and Mastery: Learning Curves for Robotic Distal Pancreatectomy at 16 International Expert Centers.

Objective: The aim of this study was to evaluate the different phases of the learning curve for robotic distal pancreatectomy (RDP) in international expert centers.

Summary Background Data: RDP is an emerging minimally invasive approach; however, only limited, mostly single center data are available on its safe implementation, including the learning curve.

Methods: Consecutive patients undergoing elective RDP from 16 expert centers across three continents were included to assess the learning curve.

Mesh-associated complications in minimally invasive ventral mesh rectopexy: a systematic review.

Background: Ventral mesh rectopexy (laparoscopic and robotic) is a common and well established treatment of rectal prolapse. Although described as safe and effective, complications, especially mesh-associated ones are often mentioned. Additionally, there is no consensus regarding the mesh type and fixation method as well as the materials used for this purpose.

Improving obesity management: Insights from the ACTION Switzerland survey of people with obesity, physicians and dietitians.

ACTION Switzerland (NCT05232786) examined obesity-related perceptions, attitudes, behaviours and potential barriers to treatment among people with obesity (PwO) and healthcare professionals (HCPs). In March/April 2022, adult PwO (body mass index ≥30 kg/m, per self-reported height/weight) and physicians/certified dietitians who manage PwO in Switzerland completed online surveys in a cross-sectional design. Overall, 1002 PwO, 125 physicians and 25 dietitians completed the survey.

Alloplastic Vascular Grafts for Venous Interposition in Pancreatic Surgery: Readily Available and Reliable.

Objective: To investigate patency and clinical outcomes of alloplastic and other venous interposition graft materials in pancreatic surgery.

Background: Vascular pancreatic surgery is increasingly performed for locally advanced pancreatic neoplasms. Different than other centers, we prefer to use alloplastic vascular graft materials for superior mesenteric vein and portal vein interposition in pancreatic surgery.

Definition and Predictors of Early Recurrence in Neoadjuvantly Treated Esophageal and Gastroesophageal Adenocarcinoma: a Dual-Center Retrospective Cohort Study.

Abstarct: BACKGROUND: Early recurrence after esophagectomy is often used as a surrogate for aggressive tumor biology and treatment failure. However, there is no standardized definition of early recurrence, and predictors for early recurrence are unknown. Therefore, we aimed to define an evidence-based cutoff to discriminate early and late recurrence and assess the influence of neoadjuvant treatment modalities for patients with esophageal or gastroesophageal-junction adenocarcinoma (EAC).

How preoperative upper gastrointestinal investigations affect the management of bariatric patients: results of a cohort study of 897 patients.

Introduction: Preoperative diagnostic protocols vary worldwide, some prioritizing safety while others question routine procedures. Building on prior research, this study explores the impact of diverse preoperative findings on bariatric management and procedure selection.

Methods: In a retrospective analysis of prospective data of over 1000 bariatric surgery patients from January 2017 to December 2022 undergoing primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) were analyzed.

Effect of a colorectal bundle in an entire healthcare region in Switzerland: results from a prospective cohort study (EvaCol study).

Introduction: Standardization has the potential to serve as a measure to mitigate complication rates. The objective was to assess the impact of standardization by implementing a colorectal bundle (CB), which comprises nine elements, on the complication rates in left-sided colorectal resections.

Patients And Methods: This prospective, multicentre, observational, cohort trial was conducted in Switzerland at nine participating hospitals.

Clinical and computed tomography outcomes after mesh-enforced hiatoplasty and anterior hemi-fundoplication in large hiatal hernia repair.

Background: The surgical technique in large hiatal hernia (HH) repair is controversially discussed and the outcome measures and follow-up schemes are highly heterogeneous. The aim of this study is to assess the true recurrence rate using computed tomography (CT) in patients with standardized large HH repair.

Methods: Prospective single-center study investigating the outcome after dorsal, mesh-enforced large HH repair with anterior fundoplication.

Bidirectional association between inflammatory bowel disease and type 1 diabetes: a nationwide matched cohort and case-control study.

Background: Co-occurrence of inflammatory bowel disease (IBD) and type 1 diabetes (T1D) has been linked to poor clinical outcomes, but evidence on their bidirectional associations remain scarce. This study aims to investigate their bidirectional associations.

Methods: A nationwide matched cohort and case-control study with IBD patients identified between 1987 and 2017.

MLX phosphorylation stabilizes the ChREBP-MLX heterotetramer on tandem E-boxes to control carbohydrate and lipid metabolism.

The heterodimeric ChREBP-MLX transcription factor complex is a key mediator that couples intracellular sugar levels to carbohydrate and lipid metabolism. To promote the expression of target genes, two ChREBP-MLX heterodimers form a heterotetramer to bind a tandem element with two adjacent E-boxes, called Carbohydrate Responsive Element (ChoRE). How the ChREBP-MLX hetero-tetramerization is achieved and regulated, remains poorly understood.

Informing Decision-making for Transected Margin Reresection in Intraductal Papillary Mucinous Neoplasm-derived PDAC: An International Multicenter Study.

Objective: To assess the prognostic impact of margin status in patients with resected intraductal papillary mucinous neoplasms (IPMN)-derived pancreatic ductal adenocarcinoma (PDAC) and to inform future intraoperative decision-making on handling differing degrees of dysplasia on frozen section.

Summary Background Data: The ideal oncologic surgical outcome is a negative transection margin with normal pancreatic epithelium left behind. However, the prognostic significance of reresecting certain degrees of dysplasia or invasive cancer at the pancreatic neck margin during pancreatectomy for IPMN-derived PDAC is debatable.

Defining non-inferiority margins in randomised controlled surgical trials: a protocol for a systematic review.

Background: The reporting of randomised controlled non-inferiority (NI) drug trials is poor with less than 50% of published trials reporting a justification of the NI margin. This is despite the introduction of the Consolidated Standards of Reporting Trials (CONSORT) extension on reporting of NI and equivalence in randomised trials. It is critical to set the appropriate NI margin as this choice dictates the conclusions of the trial.

Diverticular disease and risk of incident major adverse cardiovascular events: A nationwide matched cohort study.

Background: An increased risk of cardiovascular disease (CVD) has been reported in patients with diverticular disease (DD). However, there are knowledge gaps about specific risks of each major adverse cardiovascular event (MACE) component.

Methods: This nationwide cohort study included Swedish adults with DD (1987-2017, N=52,468) without previous CVD.
