BACKGROUND: An optimal alimentary tract reconstruction technique after laparoscopic total gastrectomy (LTG) remains controversial. The authors developed a new simple technique for intracorporeal esophagojejunal anastomosis that employs a conventional purse-string suture instrument (PSI) and circular stapler. METHODS: From May 2014 to April 2016, 41 consecutive patients with gastric cancer underwent LTG in the author's institution. Intracorporeal esophagojejunal anastomosis using the following method was attempted for all patients...

Being an emerging transdermal delivery tool, nanoemulgel, has proved to show surprising upshots for the lipophilic drugs over other formulations. This lipophilic nature of majority of the newer drugs developed in this modern era resulting in poor oral bioavailability, erratic absorption and pharmacokinetic variations. Therefore, this novel transdermal delivery system has been proved to be advantageous over other oral and/or topical drug delivery to avoid such disturbances. These nanoemulgels are basically oil-in-water nanoemulsions gelled with the use of some gelling agent in it...

Background and aims Endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone Roux-en-Y gastric bypass (RYGB) is technically challenging. We describe our multicenter experience using lumen-apposing metal stents (LAMSs) to create an endoscopic ultrasound-guided transgastric fistula (EUS-TG) to facilitate peroral ERCP in these patients. Patients and methods Thirteen patients with RYGB who underwent EUS-TG at three tertiary centers were included. EUS was used to guide puncture of the excluded stomach from the gastric pouch or jejunum; a LAMS was placed across the transgastric fistula...

Stearoyl CoA Desaturase-1 (SCD) is considered as playing an important role in the explanation of obesity. The aim of this study was to evaluate whether the DNA methylation SCD gene promoter is associated with the metabolic improvement in morbidly obese patients after bariatric surgery. The study included 120 subjects with morbid obesity who underwent a laparoscopic Roux-en Y gastric by-pass (RYGB) and a control group of 30 obese subjects with a similar body mass index (BMI) to that found in morbidly obese subjects six months after RYGB...

In this article we compare the efficacy of different pharmacological agents (ranitidine, and omeprazole) to support phage transit from stomach to distal portions of the gastrointestinal tract in rats. We show that a temporal modification of environment in the animal stomach may protect Twort-like therapeutic antistaphylococcal phage A5/80 (from bacteriophage collection of the Hirszfeld Institute of Immunology and Experimental Therapy PAS in Wroclaw, Poland) from the inactivation by gastric juice effectively enough to enable a significant fraction of orally administered A5/80 to pass to the intestine...

We have previously demonstrated promising anticancer efficacy of orally-fed whole ginger extract (GE) in preclinical prostate models emphasizing the importance of preservation of the natural "milieu". Essentially, GE primarily includes active ginger phenolics viz., 6-gingerol (6G), 8-gingerol (8G), 10-gingerol (10G), and 6-shogaol (6S). However, the druglikeness properties of active GE phenolics like solubility, stability, and metabolic characteristics are poorly understood. Herein, we determined the physicochemical and biochemical properties of GE phenolics by conducting in vitro assays and mouse pharmacokinetic studies with and without co-administration of ketoconazole (KTZ)...

A novel oral drug delivery system, TPGS modified docetaxel proniosomes (DTX-TPGS-PNs), was designed to enhance the oral bioavailability and antitumor efficiency of the poorly water-soluble drug docetaxel. DTX-TPGS-PN niosomes were 93 ± 6.5 nm in size, -18.53 ± 1.65 mV in zeta potential and exhibited spherical morphology, with an encapsulation efficiency of 97.31 ± 0.60%. The system showed sustained release in both simulated gastric and intestinal fluid. The results of caco-2 monolayer, everted gut sac model and improved single-pass intestinal perfusion model transport studies showed that DTX-TPGS-PN niosomes could significantly improve the absorption of DTX...

INTRODUCTION: Theoretically, reducing the number of ports required in minimally invasive surgery for gastric cancer would further minimize trauma associated therewith. Advances in single-site surgery have afforded surgeons the ability to perform reduced-port distal gastrectomy via a robotic approach using the Single-Site™ system, eliminating restrictions on the movement of surgical instruments. METHODS: This phase I/II study was designed as a single-arm prospective trial of reduced-port robotic distal gastrectomy (RRDG) by a single surgeon (NCT02347956)...

INTRODUCTION: Bariatric procedures result in massive weight loss, however, not without side effects. Gastric acid is known to cause marginal ulcers, situated in the small bowel just distal to the upper anastomosis. We have used the wireless BRAVO™ system to study the buffering effect of the duodenal bulb in duodenal switch (DS), a procedure in which the gastric sleeve produces a substantial amount of acid. METHODS: We placed a pre- and a postpyloric pH capsule in 15 DS-patients (seven men, 44 years, BMI 33) under endoscopic guidance and verified the correct location by fluoroscopy...

REVIEW

Gastric cancer although occurring in reduced frequency is still an important disease, partly because of the bad prognosis when occurring in western countries. This decline in occurrence may mainly be due to the reduced prevalence of Helicobacter pylori (Hp) infection, which is the most important cause of gastric cancer. There exist many different pathological classifications of gastric carcinomas, but the most useful seems to be the one by Lauren into intestinal and diffuse types since these types seldom transform into the other and also have different epidemiology...

Malignant tumor has become the top cause of deaths before the average life expectancy in Chinese population. From the variations in the morbidity rate and mortality rate of malignant tumor in the mainland of China between 2000 and 2011, the primary prevention targeting the risk factors/etiological agents significantly reduced the morbidity rates of gastric cancer, esophageal cancer, and primary liver cancer, therefore reduced the mortality rates of these cancers. However, the contribution of clinical treatments to the mortality reduction was not obviously improved during this period...

INTRODUCTION: Gastric volvulus is an uncommon disorder and can present either in the acute or chronic setting with variable symptoms. A robust blood supply of the stomach from different sources does not allow ischemia to develop early. When it occurs in the acute scenario, patients present with severe epigastric pain and retching without vomiting. Together with inability to pass nasogastric tube, they constitute Borchardt's triad.

Hyaluronan (HA) has been utilized as a supplement. However, the absorption of orally administrated HA remains controversial. The degradation and absorption of HA in the intestine were investigated in this study. HA excretion into the feces, degradation in the intestinal tract, absorption through the large intestine, and translocation to the blood and skin were examined. HA administered orally was not detected in rat feces. HA was degraded by cecal content, but not by artificial gastric juice and intestinal juice...

Endoscopic submucosal dissection (ESD) has been widely accepted as a curative treatment for gastric neoplasm. Pyloric stenosis is a chronic complication that can be caused by ESD. The aim of this study is to clarify the risk factors and management for pyloric stenosis. From January 2004 to January 2014, a total of 126 patients who underwent ESD adjacent to pylorus were reviewed retrospectively. Pyloric mucosal defect was defined as when any resection margin of ESD was involved in the pyloric ring. Pyloric stenosis was defined as when a conventional endoscope could not be passed to the duodenum...
