Long-term Outcome of the Dutch Common Channel Trial (DUCATI): Preservation of Superior Weight Loss Results Without Significant Malnutrition Side Effects.

Purpose: The optimal bowel limb lengths for laparoscopic Roux-en-Y gastric bypass (LRYGB) to maximize weight loss while minimizing nutritional deficiencies in severe obesity treatment remain a topic of debate. The multi-center Dutch Common Channel Trial (DUCATI) aims to compare the outcomes of a very long Roux Limb Roux-en-Y gastric bypass (VLRL-LRYGB) with a standard Roux-en-Y gastric bypass (S-LRYGB).

Methods: A total of 444 patients were randomly assigned in a 1:1, double-blind manner to undergo either VLRL-RYGB or S-LRYGB.

Markers for Major Complications at Day-One Postoperative in Fast-Track Metabolic Surgery: Updated Metabolic Checklist.

Introduction: In fast-track metabolic surgery, the window to identify complications is narrow. Postoperative checklists can be useful tools in the decision-making of safe early discharge. The aim of this study was to evaluate the predictive value of a checklist used in metabolic surgery.

Peroperative administration of tranexamic acid in sleeve gastrectomy to reduce hemorrhage: a double-blind randomized controlled trial.

Introduction: In metabolic surgery, hemorrhage is the most common major complication. This study investigated whether peroperative administration of tranexamic acid (TXA) reduced the risk of hemorrhage in patients undergoing laparoscopic sleeve gastrectomy (SG).

Methods: In this double-blind randomized controlled trial, patients undergoing primary SG in a high-volume bariatric hospital were randomized (1:1) to receive 1500-mg TXA or placebo peroperatively.

Nissen-Sleeve procedure versus laparoscopic Roux-en-Y gastric bypass in patients with morbid obesity and gastro-oesophageal reflux disease: protocol for a non-inferiority randomised trial (GINSBY).

Introduction: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are the most frequently performed procedures in bariatric surgery. In patients with morbid obesity and gastro-oesophageal reflux disease (GORD), LRYGB is the most accepted procedure. For patients with a contraindication for LRYGB or a strong preference for LSG, the Nissen-Sleeve procedure may be a viable new option.

Midterm Results from the Dutch Common Channel Trial (DUCATI): Superior Weight Loss Results of the Long Roux Limb Gastric Bypass in Comparison to the Standard Bypass at 3-Year Follow-Up.

Unlabelled: In the multi-center Dutch Common Channel Trial (DUCATI), a very long Roux limb Roux-en-Y gastric bypass (VLRL-RYGB: BP-limb 60 cm, Roux limb variable, and common channel 100 cm) was compared to a standard Roux-en-Y gastric bypass (S-LRYGB: BP-limb 60 cm, Roux limb 150 cm, and common channel variable) in the treatment of morbidly obese patients. As all trial patients are beyond 3-year follow-up a midterm analysis was performed to investigate the effect of the VLRL-RYGB.

Methods: A total of 444 patients were randomized (1:1) to receive either a VLRL-RYGB or a S-LRYGB.

Effects of Morbid Obesity and Metabolic Syndrome on the Composition of Circulating Immune Subsets.

Morbid obesity is characterized by chronic, low-grade inflammation, which is associated with 'inflamm-aging'. The presence of metabolic syndrome (MetS) might accelerate this phenomenon of metaflammation. In this study, we assessed the effects of morbid obesity and MetS on the composition of a broad spectrum of immune cells present within the circulation.

Does the Length of the Common Channel as Part of the Total Alimentary Tract Matter? One Year Results from the Multicenter Dutch Common Channel Trial (DUCATI) Comparing Standard Versus Distal Roux-en-Y Gastric Bypass with Similar Biliopancreatic Bowel Limb Lengths.

Purpose: Although the laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is the gold-standard bariatric procedure, it remains uncertain what the optimal bowel limb lengths are to accomplish maximal weight loss while minimizing nutritional deficiencies and related gastro-intestinal complaints. The aim of this randomized controlled multicenter trial is to investigate the effect of significant lengthening of the length of the Roux limb (RL) at the cost of the length of the common channel (CC) while keeping the biliopancreatic limb (BPL) lengths the same on both study arms.

Methods: Four hundred forty-four patients were randomized to receive either a Very Long Roux Limb LRYGB (VLRL-LRYGB) (variable RL length, BPL 60 cm, and CC 100 cm) or a Standard LRYGB (S-LRYGB) (RL 150 cm, BPL 60 cm, and a variable CC length).

Low-pressure pneumoperitoneum with deep neuromuscular blockade in metabolic surgery to reduce postoperative pain: a randomized pilot trial.

Background: For metabolic laparoscopic surgery, higher pressures up to 20 mmHg are often used to create a surgical field of sufficient quality. This randomized pilot study aimed to determine the feasibility, safety and tolerability of low intraabdominal pressure (IAP) and deep neuromuscular blockade (NMB) to reduce postoperative pain.

Methods: In a teaching hospital in the Netherlands, 62 patients eligible for a laparoscopic Roux-en-Y gastric bypass (LRYGB) were randomized into one of four groups in a 2 × 2 factorial design: deep/moderate NMB and standard (20 mmHg)/low IAP (12 mmHg).

Correction to: One anastomosis gastric bypass vs. Roux-en-Y gastric bypass, remedy for insufficient weight loss and weight regain after failed restrictive bariatric surgery.

In the original article there was a discrepancy between the XML (online) version of the article and the PDF.

One anastomosis gastric bypass vs. Roux-en-Y gastric bypass, remedy for insufficient weight loss and weight regain after failed restrictive bariatric surgery.

Background: Failure occurs in up to 60% of the patients that were treated with primary restrictive bariatric operations such as Laparoscopic Adjustable Gastric Banding (LAGB), or restrictive/metabolic operations like Laparoscopic Sleeve Gastrectomy (LSG). Insufficient weight loss and weight regain are the most commonly reported reasons of failure. The aim of this retrospective multicenter study was to compare One Anastomosis Gastric Bypass (OAGB) to Roux-en-Y Gastric Bypass (RYGB) as a revisional procedure in terms of weight loss, procedure time, complication rate and morbidity.

The Prognostic Value of the Dutch Sweet Eating Questionnaire on Weight Loss After Metabolic Surgery: a Randomized Controlled Trial.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) have shown different weight loss results. These differences might be partly due to dumping after LRYGB, forcing sweet eaters to switch to a healthy diet. The Dutch Sweet Eating Questionnaire (DSEQ) is validated to measure sweet eating.

Reducing complication rates and hospital readmissions while revising the enhanced recovery after bariatric surgery (ERABS) protocol.

Background: To optimize the postoperative phase following bariatric surgery, the enhanced recovery after bariatric surgery pathway (ERABS) has been developed. The aim of ERABS is to create a care path that is as safe, efficient and patient-friendly as possible. Continuous evaluation and optimization of ERABS are important to ensure a safe treatment path and may result in better outcomes.

Trial protocol: preoperative administration of tranexamic acid in sleeve gastrectomy (PATAS) to reduce haemorrhage rates. A randomised controlled trial.

Introduction: Fast-track protocols often include short-term thromboprophylaxis and short length of hospital stay. These treatment strategies may negatively affect the occurrence and diagnosis of postoperative haemorrhage. Over the years, the rates of venous thromboembolic events (VTEs) have decreased, while there seems to be an increase in the occurrence of postoperative haemorrhage.

The Influence of Surgical Experience on Postoperative Recovery in Fast-Track Bariatric Surgery.

Introduction: Short duration of surgery is an important aspect in fast-track protocols. Peroperative training of surgical residents could influence the duration of surgery, possibly affecting patient outcome. This study evaluates the influence of the operator's level of experience on patient outcome in fast-track bariatric surgery.

A Single-Center Comparison of Extended and Restricted THROMBOPROPHYLAXIS with LMWH after Metabolic Surgery.

Introduction: Morbid obesity is an important risk factor for developing a venous thromboembolic events (VTE) after surgery. Fast-track protocols in metabolic surgery can lower the risk of VTE in the postoperative period by reducing the immobilization period. Administration of thromboprophylaxis can be a burden for patients.

Structural and functional vascular improvement 1 year after bariatric surgery: a prospective cohort study.

Background: Obesity is a major risk factor for cardiovascular disease. Data on structural and functional arterial changes after bariatric surgery are scarce.

Objectives: The aim of this study was to determine the effects of bariatric surgery on the carotid intima media thickness (cIMT) and pulse wave velocity (PWV).

The effect of sex and menopause on carotid intima-media thickness and pulse wave velocity in morbid obesity.

Background: Women are relatively protected from cardiovascular disease compared with men. Since morbid obesity is an independent risk factor for cardiovascular disease, the current study investigated whether the association between sex and cardiovascular risk factors and outcomes can be demonstrated in subjects suffering from morbid obesity.

Materials And Methods: Two hundred subjects enrolled in a study on cardiovascular risk factors in morbid obesity underwent extensive laboratory screening, carotid intima-media thickness (cIMT) and pulse wave velocity (PWV) measurements.

A Stepwise Approach in Learning Surgical Residents a Roux-en-Y Gastric Bypass.

Introduction: This study describes a stepwise training program to teach a laparoscopic Roux-en-Y gastric bypass (LRYGB). Results of a resident are compared to experienced bariatric surgeons (EBS).

Methods: The resident performed a varying amount of surgical steps and the duration of every step was measured using video analysis.

Contribution of Type 2 Diabetes Mellitus to Subclinical Atherosclerosis in Subjects with Morbid Obesity.

Introduction: Type 2 diabetes mellitus (T2DM) and obesity are both related to increased risk of cardiovascular disease and mortality. Early atherosclerotic vascular changes can be detected by non-invasive tests like carotid artery intima-media thickness (cIMT) and pulse wave velocity (PWV). Both cIMT and PWV are significantly impaired in T2DM patients and in obese patients, but the additional effect of T2DM on these vascular measurements in obese subjects has not been evaluated.

The Standardized Postoperative Checklist for Bariatric Surgery; a Tool for Safe Early Discharge?

Background: Morbidly obese patients are at higher risk of complications after surgery. In bariatric surgery, pre- and intra-operative checklists are commonly used to identify high-risk patients preoperatively, to decrease the number of postoperative complications. This pilot study evaluates the effect of a postoperative checklist in bariatric surgery, addressing regularly measured parameters, on the occurrence and early recognition of complications.

Quality of Life 1 Year After Laparoscopic Sleeve Gastrectomy Versus Laparoscopic Roux-en-Y Gastric Bypass: a Randomized Controlled Trial Focusing on Gastroesophageal Reflux Disease.

Introduction: Bariatric surgery is the only treatment option that achieves sustained weight loss in obese patients and that also has positive effects on obesity-related comorbidities. Laparoscopic sleeve gastrectomy (LSG) seems to achieve equal weight loss as laparoscopic Roux-en-Y gastric bypass (LRYGB), but there is still much debate about the quality of life (QOL) after LSG, mainly concerning the association with gastroesophageal reflux. Our hypothesis is that QOL after LSG is comparable with QOL after LRYGB.

The Sleeve Bypass Trial: a multicentre randomized controlled trial comparing the long term outcome of laparoscopic sleeve gastrectomy and gastric bypass for morbid obesity in terms of excess BMI loss percentage and quality of life.

Background: Obesity is an increasing disease worldwide. Bariatric surgery is the only effective therapy to induce sufficient long-term weight loss for morbidly obese patients. Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is the gold standard surgical technique.
