Upper Gastrointestinal (GI) pseudomelanosis is an uncommon entity characterized by endoscopic visualization of speckled dark mucosal pigmentation. While described in the rectum and colon, 'melanosis' or more aptly 'pseudomelanosis' is rare in the duodenum and exceedingly rare in the stomach. Five cases of pseudomelanosis were encountered at our department. Four females and one male were diagnosed, with a mean age of 70 years. All patients exhibited duodenal pseudomelanosis, with one demonstrating gastric antral pseudomelanosis as well...

Morbidly obese patients exhibit impaired secretion of gut hormones that may contribute to the development of obesity. After bariatric surgery there is a dramatic increase in gut hormone release. In this study, gastric and duodenal tissues were endoscopically collected from lean, and morbidly obese subjects before and 3 months after laparoscopic sleeve gastrectomy (LSG). Tissue morphology, abundance of chromogranin A, gut hormones, α-defensin, mucin 2, Na(+)/glucose co-transporter 1 (SGLT1) and transcription factors, Hes1, HATH1, NeuroD1, and Ngn3, were determined...

INTRODUCTION: When gastric cancer or carcinoid patients have coexisting diseases such as duodenal adenoma, FAP, or Crohn's disease, periodic observation of the duodenum is necessary. METHODS: Between August 2013 and April 2015, we performed four consecutive laparoscopic total gastrectomies with double tract reconstruction for duodenal surveillance. Three of the patients were diagnosed with gastric cancer, while the remaining patient was diagnosed with gastric carcinoid...

INTRODUCTION: Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENTATION OF CASE: A 67-year-old man presents to the Emergency Room (ER) following large volume melena and complaining of syncope...

Growth depends on an animal's capacity to digest and assimilate ingested nutrients, and insufficient supply and impairment will constrain lamb growth. Eight groups of Alpine Finewool lambs were harvested on 0, 3, 7, 14, 21, 28, 42, and 56 d to measure pH and enzymatic activities in the duodenum, proximal jejunum, middle jejunum, distal jejunum, and ileum mucosa or digesta. From the duodenum to the ileum the pH of intestinal mucosa and digesta increased, whereas pH changed very little with age. The trypsin, chymotrypsin, lipase, lactase, and α-amylase activities observed at birth decreased by d 3, followed by a nonuniform enzymatic response in the small intestine...

The cationic amino acid transporter (CAT) protein family transports lysine and arginine in cellular amino acid pools. We hypothesized that CAT expression changes in pig skeletal muscles during rapid pig postnatal development. We aimed to investigate the tissue distribution and changes in the ontogenic expression of CATs in pig skeletal muscles during postnatal development. Six piglets at 1, 12, 26, 45, and 75 days old were selected from six litters, and their longissimus dorsi (LD), biceps femoris (BF), and rhomboideus (RH) muscles, and their stomach, duodenum, jejunum, ileum, colon, liver, kidney, heart, and cerebrum were collected...

The chemical variability of the intestinal lumen requires the presence of molecular receptors detecting the various substances naturally occurring in the diet and as a result of the activity of the microbiota. Despite their early discovery, intestinal bitter taste receptors (Tas2r) have not yet been assigned an unambiguous physiological function. Recently, using a CRE-recombinant approach we showed that the Tas2r131 gene is expressed in a subset of mucin-producing goblet cells in the colon of mice. Moreover, we also demonstrated that the expression of the Tas2r131 locus is not restricted to this region...

A 68-year-old Japanese woman underwent radiotherapy for gastric lymphoma. Although lymphangiectasia was sparsely observed in the second portion of the duodenum before radiotherapy, the number of pinpoint white spots obviously increased after the treatment. Although the duodenal lymphangiectasia gradually progressed, the patient had no features of protein-losing enteropathy. This case highlights the importance of endoscopic observation of the duodenum after irradiation to the abdomen as radiotherapy may secondarily cause intestinal lymphangiectasia...

Type I intestinal atresias (webs) are rare causes of gastrointestinal obstruction in infants, the most common site being the second portion of the duodenum. According to the Louw and Barnard classification, type 1 atresia has been defined as an intra-luminal web which results in either complete (web with no perforation) or incomplete (web with central perforation) intestinal obstruction. The jejunum is a rare site of such webs. Diagnosis of an incompletely obstructing web due to central perforation is usually difficult and challenging...

Clinicopathologic characteristics of paraduodenal (groove) pancreatitis (PDP) remain to be fully unraveled. In this study, 47 PDPs with preoperative enhanced images available were subjected to detailed comparative analysis in conjunction with pathologic findings. PDP were predominantly in males (3:1) with a mean age of 50 years, and 60% had a preoperative diagnosis of cancer. Mean lesional size was 3.1 cm. Three distinct subtypes were identified by imaging. Solid-tumoral (type-1) with groove-predominant (type-1A, 36%) forming a distinct solid band between the duodenum and pancreas often with histologic microabscesses (69% vs...

This report describes a patient who presented with a large gallstone obstructing the duodenal bulb, with the chief complaint of acute on chronic abdominal pain. Classically, this is known as Bouveret's syndrome or a gallstone ileus of the duodenum. Our patient's current health status presented a challenge, with the presence of several comorbidities, particularly a large abdominal aortic aneurism. We chose an open procedure for this reason. The stone was removed through a laparotomy, and the cholecystoduodenal fistula that the stone used to pass into the small bowel was repaired...

It was detected that sweet taste receptors (STRs) were expressed in L cells which secreted glucagon-like peptide-1 (GLP-1) in the gut. The STR blocker lactisole reduced GLP-1 secretion and increased blood glucose level. Therefore, we investigated the expression of sweet taste molecules in the proximal and distal small intestine, and gut hormones secretion in healthy control and type 2 diabetic rats. Two groups of rats (Sprague Dawley (SD), and Zucker diabetic fatty (ZDF)) were involved in the study. Each group (n=10) was performed by an intragastric glucose infusion (50% glucose solution, 2g/kg body weight)...

BACKGROUND: Tissue transglutaminase (tTG) immunoglobulin A (IgA) testing is a sensitive adjunct to the diagnosis of coeliac disease. The threshold for positivity was developed for diagnosis, with negative results reported as below the reference value (<4 U/mL). AIM: To investigate if an undetectable (tTG IgA<1.2 U/mL) is more predictive of healing compared to patients with negative but detectable serology (1.2-3.9 U/mL). METHODS: We performed a retrospective study of 402 treated coeliac disease patients seen at the Mayo Clinic with negative tTG IgA values drawn within 1 month of duodenal biopsy between January 2009 and December 2015...

Colorectal cancer (CRC) is a leading cause of cancer mortality. Diet has a significant influence on colon cancer risk. Identifying chemopreventive agents, dietary constituents, practices and/or diet supplements that promote gut health and reduce the incidence of intestinal neoplasias and CRC could significantly impact public health. Sphingadienes (SDs) are dietary sphingolipids found in plant-based food products. SDs are cytotoxic to colon cancer cells and exhibit chemopreventive properties. The aim of the present study was to develop a sensitive and robust ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for quantifying SDs in food products and biological samples...
