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. PRESENTATION OF CASE: We report a case which presented in the emergency department with severe abdominal pain, abdominal distension and vomiting and a previous history of pulmonary tuberculosis...

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...

BACKGROUND: Cytomegalovirus is the most common cause of congenital infection in the developed countries. Gastrointestinal involvement has been extensively described in both adult and paediatric immunocompromised patients but it is infrequent in congenital or perinatal CMV infection. CASE PRESENTATION: We report on a case of coexistent congenital Cytomegalovirus infection with intestinal malrotation and positive intestinal Cytomegalovirus biopsy. At birth the neonate showed clinical and radiological evidence of intestinal obstruction...

Trichobezoars are hairballs or hair-like fibers formed by chewing and swallowing hair or any other indigestible materials. Trichobezoars usually form in the gastric body and are thus prepyloric. However, trichobezoars may rarely pass through the pylorus into the duodenum, jejunum, ileum, and even the colon, in a condition referred to as Rapunzel syndrome. Here, we present a case of a 13-year-old girl with this rare syndrome and discuss the diagnosis and treatment of the disease.

Efforts at elimination of scourges, such as malaria, are limited by the logistic challenges of reaching large rural populations and ensuring patient adherence to adequate pharmacologic treatment. We have developed an oral, ultra-long-acting capsule that dissolves in the stomach and deploys a star-shaped dosage form that releases drug while assuming a geometry that prevents passage through the pylorus yet allows passage of food, enabling prolonged gastric residence. This gastric-resident, drug delivery dosage form releases small-molecule drugs for days to weeks and potentially longer...

INTRODUCTION: Helicobacter-induced atrophic gastritis with a hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonising acid-free stomach oxidise ethanol to acetaldehyde, a recognised group 1 carcinogen. OBJECTIVE: To assess gastric production of acetaldehyde and its inert condensation product, non-toxic 2-methyl-1,3-thiazolidine-4-carboxylic acid (MTCA), after alcohol intake under treatment with slow-release L-cysteine or placebo. METHODS: Seven patients with biopsy-confirmed atrophic gastritis, low serum pepsinogen and high gastrin-17 were studied in a cross-over single-blinded design...

Vascular changes observed in intralobar pulmonary sequestration (PS) have been reported to be similar to those observed in pulmonary hypertension (PH). However, atherosclerosis in the pulmonary artery, which is one of the characteristic arterial changes of PH, has scarcely been reported in PS. Here, we report this unique manifestation in a 66-year-old man, in whom an intralobar PS fed by an aberrant artery branching from the left gastric artery had been identified 10 years earlier, and who was diagnosed with pneumonia after having symptoms of fever and cough...

A 77-year-old woman underwent an upper gastrointestinal (UGI) endoscopy screening examination, and a 10-mm reddish, submucosal tumor-like lesion was found on the posterior wall of the fornix. Biopsy was performed, but there was no evidence of malignancy, so annual follow-up by UGI endoscopy was decided upon. After 12 years, examination of another biopsy specimen revealed an adenocarcinoma of the fundic gland type. There had been no significant change in the size or shape of the lesion over the long follow-up period...

The present study was aimed to develope a proliposomal formulation to decrease the hepatic first-pass metabolism of protocatechualdehyde (PD), followed by pellet coating to modify the drug release for angina chronotherapy. PD proliposomes were prepared by depositing PD-phospholipid complex on mannitol powders to improve the drug encapsulation. Afterwards, the PD proliposomes were prepared into pellet cores via extrusion-spheronization using 10% κ-carrageenan as pelletization aid prior to the development of PD sustained-release pellets (PD-SRPs)...

Gastric mucormycosis is a rare and life-threatening fungal disease, caused by fungus in the order Mucorales. While rhino-cerebral and pulmonary forms are common, gastric mucormycosis is an uncommon site for the disease. We diagnosed gastric mucormycosis in a 41-year-old female who had severe multiple trauma, including cardiac rupture, due to a traffic accident. Eighteen days after hospitalization, she passed 800 mL of melena over one day. We performed upper esophagogastroduodenoscopy (EGD) and found a huge gastric ulcer with bleeding...

BACKGROUND AND AIMS: EUS-guided FNA biopsy has been widely performed to aid in the diagnosis of submucosal tumors (SMTs). However, in cases of small tumors, the diagnostic yield of EUS-FNA is poor. Therefore, it is necessary to develop a new needle for the diagnosis. We developed a device with a new mechanism that we refer to as a drill needle aspiration biopsy (DNAB). The aim of this study was to evaluate the use of DNAB in resected gastric SMT specimens. METHODS: A drill needle with a sharp tip and wide ditch was inserted into a catheter for angiography...

Rodolfo J Oviedo, Chase W Sofiak, Bruce M Dixon
INTRODUCTION: Achalasia is a condition that occurs when the lower esophageal sphincter (LES) fails to properly relax, combined with slowing/failure of esophageal peristalsis. This is seen clinically by not allowing solids and liquids to pass easily into the stomach. Achalasia is not historically associated with morbid obesity, yet dual treatment of morbid obesity and achalasia is becoming more prominent due to the worldwide obesity epidemic. PRESENTATION OF CASE: Achalasia is typically a disease that affects non-obese adults over the age of 55, which makes the discussion of this case report unique in that our patient is a 23 year-old woman who successfully underwent per-oral endoscopic myotomy (POEM) in preparation for a future laparoscopic sleeve gastrectomy...

OBJECTIVE: Acquiring adequate tissue for immunohistochemical (IHC) analysis is important in the differential diagnosis of subepithelial tumors (SETs). In this study, we aimed to compare the diagnostic yield based on IHC analysis between endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and EUS-guided fine needle biopsy (EUS-FNB) after on-site cytological evaluation for cellularity in gastric SETs. METHODS: In 22 patients with gastric SETs, EUS-guided tissue sampling was performed on the same SET in a randomized sequence, with EUS-FNA followed by EUS-FNB, or vice versa...

Swati Agrawal, Sandeep Arora, Nishi Sharma
Ingestion of foreign bodies is a common pediatric problem. The majority of ingested foreign bodies pass spontaneously. Oesophageal foreign bodies should be urgently removed because of their potential to cause complications. Ingested batteries that lodge in the oesophagus, sharp or pointed foreign bodies in the oesophageal or gastric tract, and ingestion of multiple magnets all require urgent endoscopic removal. A 4-year-old boy ingested a sharp magnetic foreign body, which was removed via rigid oesophagoscopy without complication...

REVIEW
Deepanshu Jain, Nirav Thosani, Shashideep Singhal
Gastrointestinal bleeding can range from grossly visible blood in stool or vomitus to microscopic bleed. However, any kind of bleeding can lead to potential life-threatening consequences. A small proportion of patients with gastrointestinal bleeding remain refractory to initial endoscopic hemostasis. While some are successfully managed by repeat endoscopic intervention, a few fail to respond or are not amenable to endoscopic hemostasis. As of now, the next level of intervention is passed on to either surgeons or interventional radiologists...
