BACKGROUND: Morbid obesity remains one of society's significant medical dilemmas. It is rapidly worsening and expected to affect 35% of the US population by the year 2020. Common current bariatric procedures exist and include, but not limited to, the adjustable gastric band, gastric bypass, and the sleeve gastrectomy. Although beneficial to morbidly obese patients, they also alter the patient's anatomy and involve resections, or require maintenance. The goal of the trial is to show a new minimally invasive vertical gastric clip technique that produces significant weight loss but requires no resection, no change in anatomy, and is reversible...

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: Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed procedures in obesity surgery. The benefits of minimally invasive surgery include rapid recovery. We evaluated the clinical outcomes of different resection margin lengths from the pylorus in LSG. METHODS: This retrospective study included 152 patients who underwent LSG from January 2011 to October 2014. The antrum was resected 2 cm from the pylorus in 84 patients (group A) and 6 cm from the pylorus in 68 patients (group B)...

BACKGROUND: After an acute attack of pancreatitis, walled-off pancreatic fluid collections (PFC) occur in approximately 10 % of cases. Drainage of the cavity is recommended when specific indications are met. Endoscopic drainage has been adopted as the main intervention for symptomatic walled-off PFC. Altered gastric anatomy in these patients poses an interesting challenge. We present the first case of a patient with sleeve gastrectomy who underwent successful endoscopic transduodenal necrosectomy (TDN)...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has become a very popular surgical treatment for the treatment of morbidly obese patients. Staple line leaks are the major cause of severe morbidity. Reasons for leaks might be hyperpressure (mechanical theory) or hypoperfusion (vascular theory) of the narrow gastric tube. This study assessed microperfusion patterns of the stomach during LSG using visible light spectroscopy (VLS), a method to measure tissue oxygenation (saturated O2 (StO2))...

BACKGROUND: The objective of this study is to evaluate the utility of conventional ultrasonography (USG) in the evaluation of the stomach antrum and distal corpus lesions. METHODS: A prospective evaluation was made of 69 patients who underwent sleeve gastrectomy. Preoperative USG was applied to the patients and measurements were taken and recorded of the stomach antrum full layer wall thickness (USGFT) and of mucosal thickness (USGMT). Postoperatively, same parameters were again measured histopathologically and the pathological full thickness (PFT) and pathological mucosal thickness (PMT) values were compared...

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...

INTRODUCTION: Gastric lipomas are rare benign mesenchymal tumors of the stomach. CASE REPORT: We report a 41 year old, morbid obese male, admitted for elective laparoscopic sleeve gastrectomy. Thorough preoperative assessment revealed a gastric lipoma in the antrum of the stomach measuring 3×3cm. Due to the patient's preference, surgical resection of the lipoma was done along with the laparoscopic sleeve gastrectomy procedure. DISCUSSION: In our case, we report a rare case of submucosal gastric lipoma successfully removed during a laparoscopic sleeve gastrectomy...

The sleeve gastrectomy has been accepted as a primary bariatric procedure. One of the most feared complications is staple line leakage. It is important to use the right staple sizes to minimize the risk of leak. Knowledge of gastric thickness is important. The goal of this study was to measure the thickness of the gastric wall after elimination of the gastric folds in the mucosa. An electronic thickness gauge was developed that measured the anterior and posterior wall of the fresh stomach specimen together at 5 points at a pressure based on the finger pressure necessary to flatten the gastric folds...

Rose Huang, Michel Gagner
BACKGROUND: Leaks after sleeve gastrectomy (SG) may be due to a mismatch between staple height and tissue thickness. The aim of this study was to determine the range of gastric thicknesses in three areas of stapling. METHODS: SG was performed using a 40-Fr suction calibration system 4 cm from the pylorus. Measurement of combined gastric walls was accomplished with an applied pressure of 8 g/mm(2) on the fundus, midbody, and antrum. RESULTS: We enrolled 26 SG patients (15 women, 11 men; mean age 36...

BACKGROUND: Primary endoscopic weight loss therapies are of interest for access, simplicity, and economy. The objective of this manuscript is to describe the endoscopic sleeve gastroplasty used in 50 patients. METHODS: The goal of this procedure is to reduce the gastric lumen into a tubular configuration, with the greater curvature modified by a line of sutured plications. General anesthesia with endotracheal intubation is needed. An endoscopic suturing system requiring a specific double-channel endoscope delivers full-thickness sets of running sutures from the antrum to the fundus...

Whereas the remodeling of intestinal mucosa after bariatric surgeries has been the matter of numerous studies to our knowledge, very few reported on the remodeling of the residual gastric mucosa. In this study, we analyzed remodeling of gastric mucosa after Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) in rats. Diet-induced obese rats were subjected to RYGB, VSG or sham surgical procedures. All animals were assessed for food intake, body-weight, fasting blood, metabolites and hormones profiling, as well as insulin and glucose tolerance tests before and up to 5 weeks post-surgery...
