BACKGROUND: Postgraduate training has been haphazard to date. Surgeons have relied on attendance to annual meetings and multiple choice study guides to demonstrate maintenance of certification and continuing medical education. METHODS: SAGES held a retreat to develop the concept and scope of the Masters Program. Surveys were sent to SAGES members to guide curriculum development and selection of anchoring operations. RESULTS: SAGES has developed an educational curriculum across eight domains (Acute Care, Biliary, Bariatric, Colorectal, Hernia, Foregut, Flex Endoscopy, and Robotic Surrey) incorporating SAGES educational materials and guidelines, social media, coaching and mentoring...

Histological diagnosis of biliary cystadenoma is based on the type of epithelial cells lining the cyst and radiological features. The cyst-lining cells are not usually ciliated. We herein report a very rare example of an intrahepatic biliary cystadenoma with ciliated epithelial lining, which had taken us away from this diagnosis toward an intrahepatic foregut duplication cyst. Radiologically, also the lesion was deceptive, and a possibility of hydatid cyst was considered. However, immunohistochemical workup finally led us to this diagnosis...

Carnivores do not vary markedly in their digestive efficiency for protein and fat, but whether they resemble other trophic guilds (omnivores and herbivores) in this respect has not been evaluated. We collated data on apparent crude protein (CP) and crude fat (ether extracts, EE) digestibility in 157 mammal species, applying the Lucas principle of regressing digestible nutrient content against nutrient content, where the slope of the regression equation represents the true digestibility and the intercept the metabolic losses per unit dry matter intake...

The aim of this study was to improve an in vitro system in order to gather optimized information on the digestion of different forages in the horse's upper gastrointestinal tract. Therefore, foregut digestion of several forages was simulated in vitro (Part 1). The effect of different pH values on in vitro fructan degradation of two selected grasses (Part 2) was tested subsequently. Part 1: We hypothesized that our system produces representative results simulating digestive processes in the upper alimentary tract, but neglects microbial fermentation...

Mechanisms that regulate tissue-specific progenitors for maintenance and differentiation during development are poorly understood. Here, we demonstrate that the co-repressor protein Sin3a is critical for lung endoderm development. Loss of Sin3a in early foregut endoderm leads to a specific and profound defect in lung development with lung buds failing to undergo branching morphogenesis and progressive atrophy of the proximal lung endoderm with complete epithelial loss at later stages of development. Consequently, neonatal pups died at birth due to respiratory insufficiency...

Bemisiatabaci is an important vector of numerous plant viruses, including the emergent semi-persistently transmitted crinivirus Tomato chlorosis virus (ToCV). Its vector feeding behaviour is complex, with important implications for virus transmission, epidemiology and control. Thus, the objective of this study was to investigate the role of the stylet penetration activities of B. tabaci in the inoculation of ToCV in tomatoes by using the electrical penetration graph (EPG) technique. EPG recordings were classified into six categories depending on the waveforms observed...

The invasive red palm weevil, Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), is considered one of the world's most devastating insect pests to palm trees. It was observed that larvae of this pest are able to inhibit microbial growth on the rearing media when they start feeding and this observation has led us to study the effect of red palm weevils on various microbial species. The antimicrobial effect of extracts from different parts of the alimentary canal on Gram positive bacteria (Enterococcus faecalis and Staphylococcus aureus), Gram negative bacteria (Escherichia coli and Klebsiella spp...

BACKGROUND: Debate persists about the impact of a Collis gastroplasty on outcomes of antireflux operation. This study analyzed operative and quality of life outcomes from a series of 480 patients who underwent laparoscopic antireflux operation with a Collis gastroplasty reported to date. METHODS: A retrospective review was conducted to compare outcomes between patients undergoing laparoscopic antireflux operation with Collis gastroplasty versus without Collis gastroplasty at 2 large, foregut centers from October 2004 to December 2011 and July 2012 to September 2016...

We investigated the impact of pathologic differentiation (well or poorly differentiated) in metastatic grade 3 GEP-NEC patients receiving etoposide and platinum (EP)-based therapy, and evaluated a more exact Ki67 index cut-off point to select patients with grade 3 GEP-NEC who might benefit from EP-based therapy. A total of 31 patients with metastatic grade 3 GEP-NECs receiving EP-based therapy were included in this study. Primary sites included 13 foregut-derived GEP-NECs [stomach (n = 4), duodenum (n = 4), and pancreas (n = 5)] and 2 hindgut-derived GEP-NECs of the rectum...

Oral foregut duplication cysts are extremely rare lesions with approximately 57 cases reported. They are congenital cysts, located in the anterior or ventral tongue, and occur predominantly in males. They are lined by one or more types of epithelia which is limited to gastric, intestinal or respiratory epithelium. The differential diagnosis includes lymphangioma, hemangioma, ranula, epidermoid cyst, teratoma and less likely a malignant process.

Rarely, liver tissue can be seen in the umbilical cord, where it is thought to result from ectopic localization during embryogenesis. The placental parenchyma is also a rare site for this occurrence. The exact pathophysiology of ectopic liver in the placenta is unknown. It has been considered that aberrant migration or displacement of cells from the developing hepatic buds leads to ectopic liver formation, including groups of liver cells that become entrapped in the foregut as the diaphragm closes. Additional hypotheses put forward have included monodermal teratoma and hepatocellular adenoma...

Pulmonary sequestration (PMS) is a rare bronchopulmonary malformation. It has an incidence of between 0.15% to 1.7%. Likewise, cystic adenomatoid malformation (CCAM) is another relatively rare category of a bronchopulmonary malformation with a reported incidence of between 1 in 25,000 to 1 in 35,000. Moreover, a bronchopulmonary malformation with features allied to both of these forms is considered an even rarer entity. In general, bronchopulmonary malformations present with a range of non-specific symptoms...

BACKGROUND: Laparoscopic antireflux surgery (LARS) is the gold standard treatment for refractory gastroesophageal reflux disease (GERD). Traditional surgical outcomes following LARS are well described, but limited data exist regarding patient-reported outcomes. We aimed to identify preoperative characteristics that were independently associated with a high GERD health-related quality of life (GERD-HRQL) following LARS. METHODS: Clinical data from our single institution foregut surgery database were used to identify all patients with GERD who underwent primary LARS from June 2010 to November 2015...

The physiological functions of insect foregut, especially in xenobiotic detoxification, are scarcely reported because of the unimportance in appearance and insufficient molecular information. The cockroach Periplaneta americana, an entomological model organism, provides perfect material to study physiological functions of foregut tissue due to its architectural feature. Through Illumina sequencing of foregut tissue from P. americana individuals (control) or insects treated with cycloxaprid, as novel neonicotinoid insecticide, 54 193 166 clean reads were obtained and further assembled into 53 853 unigenes with an average length of 366 bp...

The hoatzin is the only known avian species that has evolved a foregut fermentation system similar to that of ruminant animals. Due to the closeness of the bird's fermentation chamber, the crop, to the bird's beak it exudes an unpleasant odour; therefore, the hoatzin is called the "cow among the birds". In addition to Eubacteria and Archaea, responsible for digestion of the vegetation they consume, the bird's crop contains a holotrich ciliate, described here for the first time in detail. Cytological staining of this isotrichid-like ciliate with the Chatton-Lwoff and Protargol staining procedures, as well as SEM and TEM, justified the establishment of the new genus Aviisotricha n...

The gut microbiome of insects plays an important role in their ecology and evolution, participating in nutrient acquisition, immunity, and behavior. Microbial community structure within the gut is heavily influenced by differences among gut regions in morphology and physiology, which determine the niches available for microbes to colonize. We present a high-resolution analysis of the structure of the gut microbiome in the Mormon cricket Anabrus simplex, an insect known for its periodic outbreaks in the western United States and nutrition-dependent mating system...

Investigations of gut microbiomes have shed light on the diversity and genetic content of these communities, and helped shape our understanding of how host-associated microorganisms influence host physiology, behavior, and health. Despite the importance of gut microbes to metazoans, our understanding of the changes in diversity and composition across the alimentary tract, and the source of the resident community are limited. Here, using community metagenomics and 16S rRNA gene sequencing, we assess microbial community diversity and coding potential in the foregut, midgut, and hindgut of a juvenile Panchlora cockroach, which resides in the refuse piles of the leaf-cutter ant species Atta colombica...

To establish the animal body plan, embryos link the external epidermis to the internal digestive tract. In Caenorhabditis elegans, this linkage is achieved by the Arcade Cells, which form an epithelial bridge between the foregut and epidermis, but little is known about how development of these three epithelia is coordinated temporally. The Arcade Cell epithelium is generated after the epidermis and digestive tract epithelia have matured, ensuring that both organs can withstand the mechanical stress of embryo elongation; mis-timing of epithelium formation leads to defects in morphogenesis...

In human neonates rapid adaptation from an aqueous intrauterine environment to permanent air breathing is the rate-limiting step for extrauterine life, failure of which justifies the existence of neonatal intensive care units. The lung develops at about 4-6 weeks' gestation in humans as a ventral outpouching of the primitive foregut into the surrounding ventral mesenchyme, termed the laryngotracheal groove. At its posterior end lie progenitor cells that form a pair of bronchial tubes, from which arise all the distal epithelial structures of the lung...
