BACKGROUND: Mutations activating the α subunit of heterotrimeric Gs protein are associated with a number of highly specific pathological molecular phenotypes. One of the best characterized is the McCune Albright syndrome. The disease presents with an increased incidence of neoplasias in specific tissues. MAIN BODY: A similar repertoire of neoplasms can develop whether mutations occur spontaneously in somatic tissues during fetal development or after birth. Glands are the most "permissive" tissues, recently found to include the entire gastrointestinal tract...

The object of this study was to describe the prenatal development and histochemical properties of mucins in the sheep gastrointestinal tract. To determine changes in the mucin profile, the sections were stained with specific histochemical stains for carbohydrates. While neutral and mixed mucins were observed in the superficial epithelial cells of the abomasal pyloric region, acidic mucins were detected in the secretory ducts and corpus of the glands. Acidic mucins consisted predominantly of sialomucins. In the duodenal villi, the number of goblet cells containing neutral mucins increased toward the end of gestation, whereas Brunner's glands contained acidic mucins until the 95th day of gestation and both acidic and neutral mucins thereafter...

BACKGROUND: Delayed gastric emptying is one of the most disturbing complications of pylorus-preserving gastrectomy (PPG) and it increases hospital stay. We investigated the clinical outcome of intraoperative manual dilatation of the pylorus as a preventive method of pyloric spasm after PPG. MATERIALS AND METHODS: We reviewed gastric cancer patients who underwent PPG between January 2014 and December 2016 at Seoul National University Hospital by a single surgeon...

Cornelia de Lange syndrome (CdLS) is a developmental disorder which is characterized by typical facial features, upper extremity malformations, and growth and cognitive delays. The genes involved in CdLS encode the cohesin complex and its associated proteins; and NIPBL mutations, which account for half of the cases, result in severe CdLS phenotypes. We describe a girl with CdLS, presenting with typical facial dysmorphism, cleft palate, hypertrichosis, upper limb hypertonicity, flexion contracture of elbows, micromelia, bilateral hearing loss, gastroesophageal reflux, and severe pyloric stenosis...

BACKGROUND: The single-anastomosis duodenal switch procedure is a type of duodenal switch that involves a loop anastomosis rather than traditional Roux-en-Y reconstruction. To date, there have been no multicenter studies looking at the complications associated with post-pyloric loop reconstruction. OBJECTIVES: The aim of the study was to report the incidence of complications associated with loop duodeno-ileostomy (DI) following single-anastomosis duodenal switch (SADS) procedures...

In spite of increasing naval activities and petroleum exploration in cold environments, there is currently a paucity of tools available to monitor oil contamination in boreal marine life, especially in sedentary (non-fish) species that dominate benthic communities. This research aimed to identify biotic sources of variation in biomarkers using subarctic echinoderms, and to identify suitable biomarkers of their exposure to hydrocarbons. The focal species included the sea star Asterias rubens, the brittle star Ophiopholis aculeata, the sea urchin Strongylocentrotus droebachiensis, and the sea cucumber Cucumaria frondosa, which are among the most abundant echinoderms in the North Atlantic and Arctic Oceans...

BACKGROUND: Early enteral nutrition has been shown to decrease complications and improve patient outcomes. Post pyloric feeding is recommended for patients with gastric intolerance or at high risk for aspiration. Feeding tube placement can be challenging and pose risk of pulmonary complications. Reliance on radiographic confirmation for feeding tube placement exposes the patient to radiation. Electromagnetic placement device (EMPD) may offer a method to minimize pulmonary complications, increase successful placement, and decrease radiation exposure to the patient...

BACKGROUND: Heterotopic gastric tissue can be found in the entire gastrointestinal tract. It is usually located in the upper intestine. Rarely, it can be found in the gallbladder. This study describes several clinically, imaging features as well as histopathology findings of heterotopic gastric tissue in gallbladder (HGM). METHODS: The radiologic database of 1 tertiary university hospital was retrospectively screened for HGM. Additionally, a systemic review of the Medline database was conducted to identify previously published cases reports...

Background: Gastrostomy for feeding disorders or swallowing dysfunctions can be complicated by persistent gastrostomy site infection (PGSI). PGSI causes nutrient leakage, with dilated PGSI requiring gastrostomy reconstruction. The purpose of this study was to evaluate the causes, patient characteristics, and perioperative management of PGSI after Nissen fundoplication and gastrostomy for patients with gastro-oesophageal reflux. Patients and Methods: The records of all patients who underwent Nissen fundoplication and gastrostomy for gastro-oesophageal reflux over the past 12 years were retrieved...

Pyloromyotomy is the tried and tested surgical procedure for successful operative treatment of pyloric stenosis. Over time, the operative approach has evolved to take advantage of cosmetically superior incisions and more recently minimally invasive surgery. During and following surgery, complications are uncommon. The specific complications of an inadequate pyloromyotomy requiring repeated procedure and mucosal perforation during an overzealous pyloromyotomy represent the ends of a spectrum within which sits the perfect procedure...

Dear Editor, delayed gastric emptying due to bilateral vagotomy after esophagectomy, has been associated with increased aspiration rates, prolonged hospital stay and impaired quality of life. A pyloric drainage procedure in an effort to reduce its incidence, most commonly a pyloroplasty, represented for years a standard part of distal esophagectomy. This trend has been reevaluated nowadays and the question that still remains open is whether we should further keep on draining pylorus during esophagectomy or not...

The gastrointestinal mucosae provide a critical barrier between the external and internal milieu. Thus, damage to the mucosa requires an immediate response to provide appropriate wound closure and healing. Metaplastic lineages with phenotypes similar to the mucous glands of the distal stomach or Brunner's glands have been associated with various injurious scenarios in the stomach, small bowel and colon. These lineages have been assigned various names including pyloric metaplasia, pseudopyloric metaplasia, ulcer-associated cell lineage (UACL) and spasmolytic polypeptide-expressing metaplasia (SPEM)...

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is one of the most common indications for non-elective surgery in the neonatal population. Multiple small prospective trials have shown that postoperative outcomes for laparoscopic versus open pyloromyotomy are equivalent or slightly better with the minimally invasive approach. This study uses a prospective national database to compare postoperative complications and length of stay for infants undergoing laparoscopic versus open pyloromyotomy...

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is a common neonatal condition treated with open or laparoscopic pyloromyotomy. 3D-printed organs offer realistic simulations to practice surgical techniques. The purpose of this study was to validate a 3D HPS stomach model and assess model reliability and surgical realism. METHODS: Medical students, general surgery residents, and adult and pediatric general surgeons were recruited from a single center. Participants were videotaped three times performing a laparoscopic pyloromyotomy using box trainers and 3D-printed stomachs...

The diagnosis of duodenal adenocarcinoma is still a complex gastrological and oncological problem. The described case illustrates the unusual character of the course, the reasonableness of the diagnostic procedures and the scope of the therapy undertaken. The causes of anemia, which was the first symptom of the disease, were not revealed in the tests carried out at this stage - gastroscopy, colonoscopy, with normal other basic laboratory tests. At the next episode, after 6 months from the first, the presence of a bleeding lesion within the duodenum was revealed...

BACKGROUND: Pylorotomy and pyloroplasty in thoracoabdominal esophagectomy are routinely performed in many high-volume centers to prevent delayed gastric emptying (DGE) due to truncal vagotomy. Currently, controversy remains regarding the need for these practices. The present study aimed to determine the value and role of pyloric drainage procedures in esophagectomy with gastric replacement. METHODS: A retrospective review of prospectively collected data was performed for all consecutive patients who underwent thoracoabdominal resection of the esophagus between January 2009 and December 2016 at the Katharinenhospital in Stuttgart, Germany...

BACKGROUND: The natural incidence of left displacement of abomasum (LDA) in dairy cows was high. The diagnosis of LDA usually relies on characteristic physical exam findings but that transabdominal ultrasound is a useful technique that has been applied to the diagnosis of gastrointestinal diseases of dairy cows in equivocal cases. METHODS: Forty dairy cows with LDA were clinically and ultrasonographically examined to determine the position and the echogenic property of the abomasum...

Gastric bezoars are rare and are usually found incidentally. They can sometimes cause severe complications, including gastric outlet obstruction (GOO) or gastric pneumatosis (GP). In cases of bezoars with GP, the optimal treatment strategy has not yet been defined. We report the case of an 89-year-old man with a history of type 2 diabetes mellitus and hypertension who presented to our emergency room with a 2-day history of upper abdominal pain, nausea, and vomiting. Physical examination revealed no rebound tenderness or guarding, and laboratory values revealed no elevation of the serum lactate level...
