INTRODUCTION: Ischemia of the tip of the alimentary limb involving the gastrojejunostomy (GJ) is an unusual complication during Roux-en-Y gastric bypass (RYGB). Revision of the GJ may be needed to manage this complication. OBJECTIVES: We present a case of inadvertent perforation of the jejunum by a gastric calibration tube, which was recognized on the table and appropriate measures are then taken. Repair of this enterotomy however then led to ischemia of the tip of alimentary limb extending to a portion of the GJ anastomosis...

Although metal(loid) bioaccessibility of ambient particulate matter, with an aerodynamic diameter of <10μm (PM10 ), has recently received increasing attention, limited research exists into standardising in-vitro methodologies using simulated lung fluid (SLF). Contradictions exist regarding which assay parameters should be adopted. Additionally, potential continuation of metal(loid) dissolution once PM10 is cleared from the lungs and passed through the gastro-intestinal tract (GIT) has rarely been addressed...

INTRODUCTION: A gastric diverticulum is a rare form of diverticular disease due to outpouching of the gastric wall. It is equally presented within both sexes and commonly occurs in fifth and sixth decades of life. Patients mostly asymptomatic but may present with mild gastric symptoms. Surgical treatment is largely dependent on the patient's symptoms, and a laparoscopic approach is usually recommended for surgery. CASE PRESENTATION: A 77-year-old gentleman presented to the outpatient clinic with a one-month history of passing black stools...

Gastrointestinal conditions along the digestive tract are the main stress to which probiotics administrated orally are exposed because they must survive these adverse conditions and arrive alive to the intestine. Adhesion to epithelium has been considered one of the key criteria for the characterization of probiotics because it extends their residence time in the intestine and as a consequence, can influence the health of the host by modifying the local microbiota or modulating the immune response. Nevertheless, there are very few reports on the adhesion properties to epithelium and mucus of microorganisms after passing through the gastrointestinal tract...

BACKGROUND: Endotracheal intubation of patients with massive regurgitation represents a challenge in emergency airway management. Gastric contents tend to block suction catheters, and few treatment alternatives exist. Based on a technique that was successfully applied in our district, we wanted to examine if endotracheal intubation would be easier and quicker to perform when the patient is turned over to a semiprone position, as compared to the supine position. METHODS: In a randomized crossover simulation trial, a child manikin with on-going regurgitation was intubated both in the supine and semiprone positions...

BACKGROUND: Obesity is on a continuous rise worldwide, and with it, novel bariatric procedures have emerged. The introduction of gastric balloons has opened up a nonsurgical option for patients opting for it. However, they still require some form of sedation and endoscopy for insertion and/or removal. OBJECTIVES: The Elipse balloon is a novel creation that has managed to bypass both these procedures; therefore, the investigation into its effectiveness is of importance...

Lanthanum (La) carbonate (LC) is one of the most potent phosphate binders that prevents the elevation of serum phosphate levels in patients with end-stage renal diseases undergoing dialysis. LC binds strongly to dietary phosphate and forms insoluble complexes that pass through the gastrointestinal tract. La deposition in patients treated with LC is a recently documented finding particularly observed in gastric mucosa. We herein describe the detailed gastric mucosal lesions in 45 LC-treated patients and address the potential underlying pathologic mechanism using oral LC administration in rats...

The aim of present study was to examine whether the digestivesystem (saliva, simulated gastric and small intestinal conditions) could break down and large intestinal microbiota could utilize the polysaccharides from Fuzhuan brick tea (FBTPS). The results showed that there was no change in molecular weight, monosaccharide content and content of reducing sugars before and after saliva, simulated gastric and small intestinal digestion, indicating that FBTPS could pass through the digestive system without being broken down and reach the large intestine safely...

With fluorescent end-labeling method, a homogenous Dendrobium huoshanense polysaccharide (GXG) that was orally administrated to mice was found to be degraded into a stable fragment (dGXG) in the stomach, where dGXG was propelled into the small intestine and absorbed into the systemic circulation. The residual GXG in the stomach could pass through the gastrointestinal tract and was excreted into faeces with a very slow fermentation in the large intestine. The simulated digestion of GXG indicated that the acidic pH condition in the gastric fluid was responsible for GXG degradation, which was supported by the oral digestion of dGXG...

The majority of foreign bodies ingested pass uneventfully through the gastrointestinal tract without endoscopic intervention. Nevertheless, certain ingested objects pose a greater risk for complications and are more challenging to remove than others. This case report describes a 49-year-old male who swallowed a cigarette lighter causing a gastric ulcer. The lighter was successfully removed by flexible endoscopy using a polypectomy snare. Urgent removal is required due to the shape of the object and its hazardous contents...

BACKGROUND: The first total laparoscopic pancreaticoduodenectomy was performed in 1994 by Gagner and Pomp. Their comments coupled with the inherent technical difficulties stifled development of the technique. In the last decade there has been a renewed interest in the technique with high volume centres publishing large series. We present our experience with the first operation completed at Dr George Mukhari Academic Hospital. METHOD: Pre-operative CT confirmed a resectable head of pancreas mass...

CONTEXT: Bariatric surgery can lead to nutrient deficiencies. Gastric by-pass (GBP) entails restriction and malabsorption, whereas, vertical banded gastroplasty (VBG) is only restrictive. OBJECTIVE: The objective of this study is to study whether GBP-patients develop iodine deficiency from malabsorption, and if GBP- and VBG-patients develop lower 24-h urinary iodine excretion (24-UIE) than obese non-operated controls (OB-controls) due to lower iodine intake. DESIGN: The Swedish Obese Subjects (SOS) study is a prospective, non-randomized study of 4047 obese patients included 1987-2001, who chose bariatric surgery or non-surgical treatment...

BACKGROUND & AIMS: Bile acids (BAs) play a key role in lipid uptake and metabolic signalling in different organs including gut, liver, muscle and brown adipose tissue. Portal and peripheral plasma BA concentrations increase after a meal. However, the exact kinetics of postprandial BA metabolism have never been described in great detail. We used a conscious porcine model to investigate postprandial plasma concentrations and transorgan fluxes of BAs, glucose and insulin using the para-aminohippuric acid dilution method...

Following intramuscular injections of 0.1 mL, 3 mg kg-1  BW-1 (1/10 LD50 ) T-2 toxin (T-2), the tissue concentration of T-2 in shrimp was quantitatively detected using LC-MS/MS. The biological half-time (t1/2 ) of T-2 in blood was 40.47 ± 0.24 min. The highest number of intramuscular T-2 shrimp could tolerate when given at blood t1/2 intervals was 4. The shrimps which were injected 5 T-2 died. The T-2 toxin highest accumulation was 0.471 ± 0.012 ng g-1  BW-1 . The effect of toxic shrimp muscle subjected to different processing conditions (high pressure, trifluoroacetic acid, acid and alkali digestions, artificial digestive juice [to simulate exposure to gastric and intestinal juices]) on mouse macrophage cells (RAW267...

Phytoconstituents have been utilized as medicines for thousands of years, yet their application is limited owing to major hurdles like deficit lipid solubility, large molecular size and degradation in the gastric environment of gut. Recently, phospholipid-complex technique has unveiled in addressing these stumbling blocks either by enhancing the solubilizing capacity or its potentiating ability to pass through the biological membranes and it also protects the active herbal components from degradation. Hence, this phospholipid-complex-technique can enable researchers to deliver the phytoconstituents into systemic circulation by using certain conventional dosage forms like tablets and capsules...

BACKGROUND: Proximal early gastric cancer is a good indication for totally laparoscopic proximal gastrectomy (TLPG) with double-tract reconstruction (DTR). However, when most of the dietary intake passes through the escape route of the jejunum, the functional benefits of proximal gastrectomy might be similar to those after total gastrectomy. Our DTR procedure was improved for easy passage through the remnant stomach. The purposes of this study were to present a novel technique for intracorporeal DTR using linear staplers after TLPG and to investigate surgical outcomes...

The oral cavity displays one potentially attractive route that is not associated with gastric transit and hepatic first pass metabolism. However, poorly soluble active candidates require a drug delivery system to facilitate their transport through oral biological membranes. To this end, nanostructured lipid carriers (NLC) were loaded with Domperidone and produced with high pressure homogenization. NLC were characterized regarding particle size, particle size distribution, zeta potential, entrapment efficiency and crystallinity...

In the current study the influence of different lipid-based formulations (Pickering and nanoemulsions) and their droplet size on curcumin encapsulation and bioaccessibility, as well as on its anti-oxidant activity was investigated. Oil-in-water Pickering emulsion stabilized by chitosan-tripolyphosphate (CS-TPP) nanoparticles and nanoemulsions containing an organic phase (Span80:Tween80), were prepared with either medium chain triglyceride (MCT) or corn oil as long chain triglyceride (LCT). An in vitro gastrointestinal (GIT) model consisting of mouth, gastric and intestinal phases was used to characterize the rate and extent of lipid phase digestion of the ingested samples...
