Background: Laparoscopic vertical sleeve gastrectomy (LVSG) has overtaken the laparoscopic Roux-en-Y gastric bypass (LRYGB) as the most frequently performed bariatric surgical procedure. To date little has been reported on the long-term outcomes of the LVSG procedure comparative to the traditionally favoured LRYGB. We undertook a systematic review and meta-analysis to review the 5-year outcomes of comparing LVSG and LRYGB. Read More

Background: Improving operating room (OR) inefficiencies has financial and operational ramifications. However, their incidence has not been systematically studied, especially in bariatric surgery.

Objectives: The study aimed to identify the operational inefficiencies of the laparoscopic Roux-en-Y gastric bypass (LRYGB) procedure, specify the steps of the procedure, and investigate whether the inefficiencies are related to case-by-case variability, using a surgical application. Read More

Background: In Argentina, health insurances demand a 24-month duration preoperative weight loss program (POWLP) before bariatric surgery. It is unknown whether it enhances weight loss before or after surgery, or even if it is related to comorbidity remission. The main objective of this study was to determine its effectiveness and reliability. Read More

Division of General Surgery, Department of Surgery, Vienna Medical University, Waehringer Guertel 18-20, 1090, Vienna, Austria.

Purpose: Bariatric-metabolic surgery in superobese patients (BMI > 50 kg/m) is very challenging indeed with little room for error. In many cases, a two-step procedure is required, since more complex primary bariatric procedures can be technically demanding and bearing a relevant risk for the patient. At our institution, laparoscopic sleeve gastrectomy (SG) is the preferred primary procedure, followed by a conversion to either SADI-S or Roux-en-Y gastric bypass (RYGB) after initial weight loss is achieved [1, 2].

Background: Single anastomosis duodenoileal bypass with sleeve gastrectomy (SADI-s) is a well-known and accepted technique for extreme obesity but technically challenging in this group of patients and so frequently is performed as a laparoscopic staged procedure. Robotic devices such as Da Vinci® system may solve some limitations of laparoscopic surgery. The video shows a really totally robotic SADI-s (RTR-SADI-s) in a single stage on a patient with extreme morbid obesity and a non-reducible umbilical hernia. Read More

 Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP) (EDGE) is a novel technique for managing pancreaticobiliary diseases in patients with a history of Roux-en-Y Gastric Bypass (RYGB). It has shown to have high technical success rates and fewer adverse events as compared to laparoscopic-assisted ERCP (LA-ERCP).

The association between obesity and gastroesophageal reflux disease (GERD) is very well known and the pathophysiology of GERD is not completely understood but is likely to have a multifactorial nature especially after bariatric procedures. The current editorial summarizes the principal mechanisms involved in the reflux disease following different bariatric procedures. Laparoscopic adjustable gastric banding could reduce the gastroesophageal reflux in the short term in some cases, but overeating will inevitably lead to enlargement of the pouch with loss of its antireflux properties.

Purpose Of Review: Knowledge regarding postoperative outcomes after bariatric and metabolic surgery continues to evolve. This review highlights key findings in outcomes research over the last 5 years related to weight loss, remission of obesity-related disease, reflux, revisional surgery, robotic-assisted surgical platforms, and adolescent populations.

Recent Findings: Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) produce similar weight loss patterns at 5 years, while duodenal switch (BPD/DS) and related procedures are associated with maximal weight loss overall and optimal resolution of obesity-related comorbidities. Read More

Retrograde intussusception (RI), although relatively uncommon, has been increasingly seen in adults post Roux-en-Y gastric bypass (RYGB) surgery. The exact mechanism for its occurrence remains unknown but several theories have attributed it to bowel persialtic dysmotility. The increase in bariatric surgery over the last decade has resulted in a proportionate increase in the number of cases of intussusception seen globally.

BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has become the most common surgical procedure performed in bariatric surgery. Large hiatal hernias and Barrett's esophagus are the only contraindications recognized among experts. However, some studies have suggested that LSG may exacerbated gastroesophageal reflux disease (GERD) symptoms or induce postoperative GERD de novo. Read More

Introduction: While laparoscopic sleeve gastrectomy (LSG) has recently emerged as the predominant surgery type for the national bariatric cohort, the literature suggests that laparoscopic Roux-en-Y gastric bypass (LRYGB) may be more effective in normalizing gastroesophageal physiology for the subset of patients with GERD. This study explored practice patterns over time for patients with GERD or hiatal hernia, a related comorbidity, undergoing bariatric surgery.

Methods: Data for LSG and LRYGB were extracted from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) datasets for 2015-2018. Read More

Purpose: While over 200 million opioid prescriptions are written annually for chronic pain in the USA, little has been written on the impact of opioids on bariatric surgery, specifically on the effects of prescription opioid use on weight loss post laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG).

Materials And Methods: We completed a matched-cohort, retrospective review in 1176 consecutive patients undergoing primary bariatric surgery at a single institution. Patients were grouped into chronic prescription opioid users (POU), defined as ongoing opioid use for > 3 months at the time of surgery, and opioid-naïve controls (CON), defined as no opioid use prior to surgery.

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). Read More

Importance: Few studies have described the longitudinal trajectories of serum levels of micronutrients whose deficiencies are associated with serious sequelae following bariatric procedures, such as anemia, osteoporotic fractures, and neuropathies. Furthermore, previous studies comparing laparoscopic sleeve gastrectomy (LSG) vs Roux-en-Y gastric bypass (LRYGB) or one-anastomosis gastric bypass (OAGB) procedures may have been limited by selection and confounding biases.
