#1
Shengxian Fan, Jing Wang, Yousheng Li
Duodenal phytobezoar, an unusual cause of acute duodenal obstruction, is rarely seen. The most common cause of this type of bezoar is persimmon. It frequently arises from underlying gastrointestinal tract pathologies (gastric surgery, etc.). Here, we report the case of a 66-year-old man who had undergone distal gastrectomy with Billroth I reconstruction for gastric cancer and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. The abdominal computed tomography scan showed a large-sized mass in the horizontal portion of the duodenum...

BACKGROUND: The distal splenorenal shunt is an effective procedure for the treatment of portal hypertension in children. However, there has been no report about laparoscopic distal splenorenal shunt in the treatment of portal hypertension in children. METHODS: From December 2015 to August 2016, 4 children with upper gastrointestinal bleeding underwent laparoscopic distal splenoadrenal shunt. Portal hypertension and splenomegaly were demonstrated on the preoperative computed tomography (CT) and sonography...

The muskox ( Ovibos moschatus ) population inhabiting the eastern North Slope (ENS) of Alaska declined dramatically during 1999-2006, whereas populations in western Alaska (WA) were stable or increasing. To understand morbidity and mortality factors contributing to the decline, Alaska Department of Fish and Game conducted pathologic investigations of carcasses from 2005 until 2008. Additionally, archived sera from both ENS and WA muskoxen collected during 1984-1992, before the documented beginning of the ENS decline; sera collected during 2000, near the beginning of the decline; and contemporary sera (from live capture-release, adult females) collected during 2006, 2007, and 2008 were analyzed to determine whether prevalence of antibody to potential pathogens differed in the two areas or changed over time...

INTRODUCTION: Primary colorectal sarcomas are a rare entity with anecdotally poor outcomes. We sought to inform surgeons, oncologists, and researchers of the characteristics and outcomes of these understudied and difficult-to-manage tumors. METHODS: The National Cancer Data Base (NCDB) was queried for patients with pathologically confirmed primary sarcoma of the colon or rectum (1998-2012). Gastrointestinal stromal tumors were excluded. Unadjusted overall survival was reported using the Kaplan-Meier method...

Communication between the brain and gut is not one-way, but a bidirectional highway whereby reciprocal signals between the two organ systems are exchanged to coordinate function. The messengers of this complex dialogue include neural, metabolic, endocrine and immune mediators responsive to diverse environmental cues, including nutrients and components of the intestinal microbiota (microbiota-gut-brain axis). We are now starting to understand how perturbation of these systems affects transition between health and disease...

Gastrointestinal dysfunction is one of several physiologic complications in patients with traumatic brain injury (TBI). TBI can result in increased intestinal permeability due to apoptosis of intestinal epithelial cells, which contain a large number of mitochondria for persisting barrier function. Autophagy of damaged mitochondria (mitophagy) controls the quality of the mitochondria and regulates cellular homeostasis. However, the exact mechanism of mitophagy that underlies the pathological changes induced by TBI is unknown...

Several members of the SLC9A family of Na(+)/H(+) exchangers are expressed in the gut, with varying expression patterns and cellular localization. Not only do they participate in the regulation of basic epithelial cell functions, including control of transepithelial Na(+) absorption, intracellular pH (pH i ), cell volume, and nutrient absorption, but also in cellular proliferation, migration, and apoptosis. Additionally, they modulate the extracellular milieu in order to facilitate other nutrient absorption and to regulate the intestinal microbial microenvironment...

OBJECTIVE: Constipation is a common non-motor symptom of Parkinson's disease (PD). Although pathology of the enteric nervous system (ENS) has been associated with constipation in PD, the contribution of catecholaminergic neurodegeneration to this symptom is currently debated. The goal of this study was to assess the effects of the neurotoxin 6-hydroxydopamine (6-OHDA) on the colonic myenteric plexus and shed light on the role of catecholaminergic innervation in gastrointestinal (GI) function...

CDX2 is a sensitive and specific marker of intestinal differentiation. It is routinely used in surgical pathology, as its expression within a tumor favors an origin within the gastrointestinal tract. We had anecdotally encountered occasional hepatocellular carcinomas (HCC) that were CDX2 positive. CDX2 expression in HCC has not yet been reported but it has also not been examined in detail. Therefore, we evaluated CDX2 expression in a large number of resected HCCs. Full tumor sections from 172 resected HCCs and 6 resected fibrolamellar carcinomas (FLC) were stained for CDX2...

Select group of patients with concurrent esophageal and gastric stricturing secondary to corrosive intake requires colonic or free jejunal transfer. These technically demanding reconstructions are associated with significant complications and have up to 18% ischemic conduit necrosis. Following corrosive intake, up to 30% of such patients have stricturing at the pyloro-duodenal canal area only and rest of the stomach is available for rather less complex and better perfused gastrointestinal reconstruction. Here we describe an alternative technique where we utilize stomach following distal gastric resection along with Roux-en-Y reconstruction instead of colonic or jejunal interposition...

The growth of human population and deficient pollution control measures pose significant challenge to the environment. Despite conservation efforts, all sea turtle species are at some risk of extinction. The present study investigated the effect of marine debris on the gastrointestinal tract of green turtles in southeastern Brazil. Of the 777 animals evaluated, 290 showed marine debris in one segment of the gastrointestinal tract. The presence of these materials in the gastrointestinal tract may be harmful, independent of the segment involved, and increases the risk of impaction...

BACKGROUND: Bleeding from the small bowel is a rare pathology that represents 5-10% of gastrointestinal bleeding; 0.06% to 5% of cases are due to the presence of diverticula of the small intestine. The majority of diverticula are asymptomatic and present symptoms when there is a complication. CLINICAL CASE: We present the case of a 53-year-old male with a history of chronic renal failure and hypertension. While he was hospitalized due to cerebrovascular disease he recurrently presented lower gastrointestinal bleeding that required blood transfusion on several occasions...
