Sonja Chiappetta, Christine Stier, Oliver Scheffel, Sophia Theodoridou, Rudolf Weiner
INTRODUCTION: The established single-anastomosis-duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is based on a sleeve gastrectomy (SG) as the restrictive part of the procedure. Due to preserved pylorus, SG has the disadvantage of a high-pressure system with de novo or worsening of existing gastroesophageal reflux disease (GERD). CASE PRESENTATION: A female patient presented herself due to protracted GERD and weight regain after multiple bariatric surgeries...

BACKGROUND: Bariatric surgery is a well-tolerated and effective treatment for severe obesity. Newer surgical techniques and equipment have improved safety standards surrounding bariatric surgery. In particular, buttressing of the staple line in sleeve gastrectomy has decreased rates of clinically significant postoperative bleeding. The present study investigates the effectiveness of buttressing the circular stapled anastomosis during laparoscopic Roux-en-Y gastric bypass (LRYGB). SETTING: Academic, accredited hospital...

Bezoars are collections of undigested foreign material that accumulate in the gastrointestinal tract. The most common are phytobezoars, which are formed from plant fibers, especially those related to the ingestion of persimmon. Patients who undergo abdominal surgery, including bariatric surgery for obesity, and particularly gastrectomy, are prone to bezoar formation due to reduced gastric motility, loss of pyloric function, and hypoacidity. Bezoars can form months to years postoperatively. Our objective was to review the published literature regarding phytobezoar formation after bariatric surgery...

BACKGROUND: There is a scarcity of data available to determine the safety and effectiveness of bariatric surgery in the elderly population. Additionally, there are no studies showing the effect of the single anastomosis duodenal switch (SADS) has on the elderly obese, in comparison with other more popular procedures. Here we compare laparoscopic gastric band surgery (LAGB), Laparoscopic Roux-en-Y gastric bypass surgery (LRYGB), and the SADS to analyze the weight loss, perioperative and postoperative morbidity in the patients >70 years of age at a single US center...

BACKGROUND AND AIMS: Unsatisfactory weight loss after gastric bypass or sleeve gastrectomy in super-obese patients (body mass index > 50) is a growing concern. Biliopancreatic diversion with duodenal switch results in greater weight loss, but is technically challenging to perform, especially as a laparoscopic procedure (Lap-DS). The aim of this study was to compare perioperative outcomes of Lap-DS and the corresponding open procedure (O-DS) in Sweden. MATERIAL AND METHODS: The data source was a nationwide cohort from the Scandinavian Obesity Surgery Registry and 317 biliopancreatic diversion with duodenal switch patients (mean body mass index = 56...

BACKGROUND: Recent data show that some patients will have insufficient weight loss or experience weight regain after sleeve gastrectomy. Dilation of the sleeve over time or use of an inadequate technique may contribute to relapse of morbid obesity. Repeat sleeve gastrectomy is the most obvious option but requires stapling of scarred tissue, has a higher risk of leakage, and is prone to re-enlargement with time. We herein describe a simple and innovative technique with which to revise vertical sleeve gastrectomy (VSG) into functional single-anastomosis gastric bypass (f-SAGB)...

Background: Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. Aim: To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Methods: Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients...

BACKGROUND: Single anastomosis gastric bypass (SAGB) has been established as a safe and effective bariatric procedure. SAGB has also been suggested as a conversion option from other procedures, but so far not extensively explored in that direction. METHODS: The study retrospectively reviewed and analyzed 154 consecutive SAGB procedures, including 48 conversional SAGB (cSAGB) and 106 primary SAGB (pSAGB). Preoperative physical dimensions and perioperative complications were obtained...

INTRODUCTION: The single anastomosis sleeve ileal (SASI) bypass is a Novel Metabolic/Bariatric Surgery operation based on mini gastric bypass operation and Santoro's operation in which a sleeve gastrectomy is followed by a side to side gastro-ileal anastomosis. The purpose of this Study is to report the clinical results of the outcomes of SASI bypass as a therapeutic option for obese T2DM patients. METHODS: We conducted a retrospective cohort study of type 2 diabetic obese patients who underwent SASI bypass at one hospital from March 1, 2013 to December 31, 2014...

BACKGROUND: In one anastomosis gastric bypass (OAGB), the measurement of the afferent limb starting at the angle of Treitz may result in insufficient absorptive surface of the intestine of the remaining efferent limb. To address this concern, we recently modified the technique of OAGB by constructing the gastrointestinal anastomosis at a fixed distance from the ileocecal valve (i.e., 300 cm). We adopted the new concept and named it the single anastomosis gastro-ileal bypass (SAGI). METHODS: Seven consecutive patients with morbid obesity underwent the SAGI procedure...

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) is a very effective treatment for obesity and its related co-morbidities. However, some patients fail to achieve>50% of their excess weight loss (EWL), and others regain much of the weight that they lost. OBJECTIVE: The purpose of this study was to analyze early outcomes after conversion of RYGB to duodenal switch (DS) in terms of weight loss, change in co-morbidities, and complications. SETTING: This is a retrospective analysis from 1 surgeon at a single private institution...

Bariatric surgery was developed with the aim of weight reduction. Success was defined only by excess weight loss. Other indices of resolution of metabolic co-morbidities were reported but were mostly secondary. Several communications have reported that regardless of body mass index (BMI), complete or partial remission of type 2 diabetes (T2D) is possible with such traditional gastrointestinal operations as the Roux-en-Y gastric bypass, bileopancreatic diversion, and sleeve gastrectomy. These results mostly occur before weight loss, positioning metabolic surgery as a good tool for controlling the current T2D epidemic...

BACKGROUND: Obesity is the most frequent chronic metabolic disease globally. There is a direct correlation between increasing body mass index (BMI) and elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and triglycerides (Tg), and an inverse correlation with high-density lipoprotein cholesterol (HDL); all these lipid derangements are associated with an increased risk of cardiovascular disease. Our aim was to evaluate lipid profiles in morbidly obese patients before and after one-anastomosis gastric bypass (OAGB) performed at a single-center during a 2-year follow-up...

BACKGROUND: Insufficient weight loss (percentage of excess weight loss [%EWL]<50%) is observed in approximately 20% of patients after Roux-en-Y gastric bypass (RYGB). Surgical revision can be performed by various procedures including malabsorptive techniques. Conversion to a biliopancreatic diversion with duodenal switch (BPD/DS) remains a complex technique which cannot always be performed as a one-stage procedure. OBJECTIVES: This study evaluates the conversion of RYGB to BPD/DS using a novel gastric reconstruction technique based on a "hybrid sleeve" using the existing gastrojejunal anastomosis of the RYGB...

The mini-gastric bypass (MGBP) is becoming an increasingly popular procedure worldwide. It is based on an "omega" reconstruction, resulting in a single anastomosis and in potential shortening of operative time. Internal hernia represents a potentially life-threatening complication after laparoscopic Roux-en-Y gastric bypass, but it has not yet been reported after a mini-gastric bypass. We herein describe, for the first time, a case of internal hernia after this surgery.

BACKGROUND: Laparoscopic gastric bypass is a commonly performed bariatric surgery for the treatment of morbid obesity. Revision surgery for patients who have gastric bypass complications is a challenge for bariatric surgeon. Our aim is to present the early results of the conversions of gastric bypass complications to sleeve gastrectomies. METHODS: From January 2001 to April 2015, 49 of 2382 gastric bypasses underwent revisional surgery to convert gastric bypasses to sleeve gastrectomies...

BACKGROUND: The Roux-en-Y gastric bypass (GBP) has been considered the gold standard for many years. The loop duodenal switch (LDS) is a relatively new procedure that simplifies the complexity of the duodenal switch (BPDDS) by making it a single anastomosis procedure while at the same time giving it more intestinal absorption to reduce the rates of malnutrition associated with traditional BPDDS. This paper seeks to compare the 18-month weight loss outcomes and complications of the more standard GBP with the newer LDS in a single US center...
