Selective effect of laparoscopic Roux-en-Y gastric bypass on lipid metabolism.

Introduction: Bariatric surgery (BS) has shown to reduce cardiovascular morbidity and mortality in obesity. The BS has improved the dyslipidemia of the insulin resistant patient, our objective was to evaluate if there was a difference in the lipid profile between the laparoscopic roux-en-Y gastric bypass (RYGB) technique vs. the sleeve gastrectomy (SG) technique at 18 months of follow-up.

Chronic Gastric Dilation-Surgical Management.

Chronic dilation of the gastric remnant is a rare complication, although it can be serious. It is due to an exaggerated distension of the gastric remnant after a Roux-en-Y gastric bypass (RYGB). Clinical suspicion and computed tomography (CT) are essential for its diagnosis.

Image-Guided Surgical Simulation in Minimally Invasive Liver Procedures: Development of a Liver Tumor Porcine Model Using a Multimodality Imaging Assessment.

Image-guided liver surgery and interventions are growing as part of the current trend to translate liver procedures into minimally invasive approaches. Hands-on surgical training in such techniques is required. Consequently, a meaningful and realistic liver tumor model using multi-imaging modalities, such as ultrasound (US), computed tomography (CT), magnetic resonance (MR), cone beam-CT (CBCT), is mandatory.

Image-Guided Surgery for Common Bile Duct Stones After Roux-en-Y Gastric Bypass.

The relationship between obesity with common bile duct stone (CBDS) is close and increases after a Roux-en-Y gastric bypass (RYGB). Due to the anatomical modification, direct endoscopic access is not always possible. For this reason, image-guided surgery (IGS) by percutaneous transhepatic biliary drainage (PTBD) of the common bile duct (CBD) could be a first-line approach for the treatment of post-RYGB choledocholithiasis.

Image-Guided Surgical Training in Percutaneous Hepatobiliary Procedures: Development of a Realistic and Meaningful Bile Duct Dilatation Porcine Model.

Malignant or benign biliary obstructions can be successfully managed with minimally invasive percutaneous interventions. Since percutaneous approaches are challenging, extensive training using relevant models is fundamental to improve the proficiency of percutaneous physicians. The aim of this experimental study was to develop an training model in pigs to simulate bile duct dilatation to be used during percutaneous biliary interventions.

Acute Gastric Dilation of the Post-Roux-en-Y Gastric Bypass Remnant Stomach: Image-Guided Surgery Approach.

Bariatric surgery is an effective treatment for obesity and its associated morbidities. They are safe surgeries, their general complication rate is 0%-10%. However, acute gastric dilation is an unusual complication.

Applications of Elastography in Ablation Therapies: An Animal Model Study.

Ablation therapies are one of the main local treatments for solid organ tumors. After applying any ablation therapy, few days should be waited to perform an imaging study and analyze the result. In this work, we analyzed the correlation between elastography monitoring after procedure and the result of ablation.

Percutaneous Image-Guided Surgery in Complications After Bariatric Surgery.

Although bariatric surgery is a standardized procedure, it is not without complications. Image-guided surgery allows minimally invasive resolution of complications, making it ideal for bariatric patients. The objective of this work was to analyze the image-guided surgery approach to postoperative complications of bariatric surgery.

Revisional Surgery: Aphagia After Gastric Bypass.

Gastric bypass is one of the most widely performed bariatric procedures worldwide and continues to be the gold standard in obese patients with metabolic disorders. Regarding the complications, these can appear early or late, the most frequent of the latter being anastomosis stenosis, especially the gastrojejunal (G-J) stenosis. The first treatment option in stenosis is the endoscopic approach, but in cases wherein it fails or the diagnosis is kinking, revisional surgery should be performed.

N-SLEEVE GASTRECTOMY: AN OPTION FOR OBESITY AND GERD.

Background: Obesity represents a growing threat to population health all over the world. Laparoscopic sleeve gastrectomy induces alteration of the esophagogastric angle due to surgery itself, hypotony of the lower esophageal sphincter after division of muscular sling fibers, decrease of the gastric volume and, consequently, increase of intragastric pressure; that's why some patients have reflux after sleeve.

Aim: To describe a technique and preliminary results of sleeve gastrectomy with a Nissen fundoplication, in order to decrease reflux after sleeve.

Laparoscopic Sleeve Gastrectomy: How Do I Do It.

Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure in the world. LSG is a safe and effective primary bariatric procedure with durable weight loss. We believe LSG should not be called "easy" and should be performed only by surgeons trained in bariatric surgery.

Percutaneous Image-Guided Abdominal Interventions for Leaks and Fistulas Following Sleeve Gastrectomy and Roux-en-Y Gastric Bypass.

Background: Bariatric surgery offers the only effective long-term weight loss therapy for morbidly obese patients. Numerous studies have demonstrated a mortality and morbidity reduction associated with weight loss surgery, but these interventions also have significant rates of complications. It is important for the bariatric surgeons to recognize these complications and acknowledge which of them can be solved in a minimally invasive manner in order to offer to patients the best treatment.

Mixed reality navigation system for ultrasound-guided percutaneous punctures: a pre-clinical evaluation.

Image-guided surgery is growing in importance with each year. Various imaging technologies are used. The objective of this study was to test whether a new mixed reality navigation system (MRNS) improved percutaneous punctures.

STAGES AND FACTORS OF THE "PERIOPERATIVE PROCESS": POINTS IN COMMON WITH THE AERONAUTICAL INDUSTRY.

Background: The aeronautical industry is one of the disciplines that most use control systems. Its purpose is to avoid accidents and return safer flights. The flight of an airplane, from its takeoff to its landing is a process divided into stages under strict control.

THE CRITICAL VIEW OF SAFETY PREVENTS THE APPEARANCE OF BILIARY INJURIES? ANALYSIS OF A SURVEY.

Background: The risk of bile duct injury (BDI) during cholecystectomy remains a concern, despite efforts proposed for increasing safety. The Critical View of Safety (CVS) has been adopted promoting to reduce its risk.

Aim: To perform a survey to assess the awareness of the CVS, estimating the proportion of surgeons that correctly identified its elements and its relationship with BDI.

PERCUTANEOUS RADIOFREQUENCY ASSISTED LIVER PARTITION WITH PORTAL VEIN EMBOLIZATION FOR STAGED HEPATECTOMY (PRALPPS).

Background: When a major hepatic resection is necessary, sometimes the future liver remnant is not enough to maintain sufficient liver function and patients are more likely to develop liver failure after surgery.

Aim: To test the hypothesis that performing a percutaneous radiofrecuency liver partition plus percutaneous portal vein embolization (PRALPPS) for stage hepatectomy in pigs is feasible.

Methods: Four pigs (Sus scrofa domesticus) both sexes with weights between 25 to 35 kg underwent percutaneous portal vein embolization with coils of the left portal vein.

Percutaneous Image-guided Surgery Training: Model IHU-DAICIM.

The evolution of guided imaging surgery is well known in recent years. As the field of action becomes more specific, learning and teaching are also more specific. State-of-the-art medical training should be mandatory in the field of general medicine and surgery in particular.

Metabolic surgery: gastric bypass for the treatment of type 2 diabetes mellitus.

Type 2 diabetes mellitus (T2DM) is one of the largest health emergencies of the 21st century given the worldwide increase of obesity during the last decades and its close association. T2DM is an inherited, polygenic and chronic disease caused by the interaction between several genetic variants in genes and the environment. The continuous search for new and more effective tools to achieve appropriate glycemic control became imperative in order to reduce long-term complications and mortality rates related to T2DM.

SIMPLIFIED LAPAROSCOPIC GASTRIC BYPASS WITH GASTROJEJUNAL LINEAR MECHANICAL ANASTOMOSIS: TECHNICAL ASPECTS.

Background: Gastric bypass is a restrictive and malabsorptive surgery. The restrictive part consists in the creation of a small gastric pouch. The gastrointestinal bypass serves as the malabsorptive element.

Most common robotic bariatric procedures: review and technical aspects.

Since its appear in the year 1997, when Drs. Cadiere and Himpens did the first robotic cholecystectomy in Brussels, not long after the first cholecystectomy, they performed the first robotic bariatric procedure. It is believed that robotically-assisted surgery's most notable contributions are reflected in its ability to extend the benefits of minimally invasive surgery to procedures not routinely performed using minimal access techniques.

[Gastric Bypass versus Sleeve gastrectomy: comparison between type 2 Diabetes weight loss and complications. Review of randomized control trails].

Introduction: Obesity today is a major health problem worldwide and the leading health problem in Western countries because it is associated with multiple comorbidities that increase the mortality of these patients.

Material And Methods: A review of the literature was done in PubMed (Medline) and Cochrane Library of randomized controlled trials comparing gastric bypass with sleeve gastrectomy in the treatment of obesity and type 2 diabetes mellitus (T2DM). Eighteen papers were found, of which eleven met the initial inclusion criteria.

Late surgical complications after gastric by-pass: a literature review.

Introduction: Gastric bypass is today the most frequently performed bariatric procedure, but, despite of it, several complications can occur with varied morbimortality. Probably all bariatric surgeons know these complications, but, as bariatric surgery continues to spread, general surgeon must be familiarized to it and its management. Gastric bypass complications can be divided into two groups: early and late complications, taking into account the two weeks period after the surgery.
