BACKGROUND: Surgical trainees are required to develop competency in a variety of laparoscopic operations. Developing laparoscopic technical skills can be difficult as there has been a decrease in the number of procedures performed. This study aims to develop an inexpensive and anatomically relevant model for training in laparoscopic foregut procedures. METHODS: An ex vivo, anatomic model of the human upper abdomen was developed using intact porcine esophagus, stomach, diaphragm and spleen...

INTRODUCTION: Laparoscopic fundoplication is the gold standard treatment for gastroesophageal reflux disease (GERD) refractory to medical management. Although many studies have compared Nissen fundoplication (NF) to Toupet fundoplication (TF), it is unclear which operation provides the best long-term reflux control. The objective of this study was to evaluate long-term quality-of-life (QoL) outcomes after NF versus TF. METHODS: Clinical data from our single academic institutional foregut database were used to identify patients who underwent NF or TF (June 2010 to May 2016)...

The field of laparoscopic surgery has continued to grow exponentially over the years, prompting new innovative technologies. Despite substantial advancements, standard laparoscopic tools have undergone little design changes and fail to optimize mobility in limited spaces. Advancements in robotics have attempted to address this, allowing for increasing degrees of freedom and articulation of instruments. Even so, this system has proven to be cumbersome with questionable cost-effectiveness. In this study, we present the first use of a solely mechanical intuitively controlled articulating laparoscopic needle driver...

A 78-year-old man presented to the accident and emergency department with acute abdominal pain. A CT scan done to investigate the pain showed an intra-abdominal abscess medial to the caecum and an incidental exophytic lesion in the gall bladder. This was excised during surgery and sent for histological examination. Histology showed a ciliated foregut cyst of the gall bladder. A literature review revealed that this was the 13th case worldwide, as ciliated foregut cysts are usually found either above the diaphragm or in the liver...

Stability in gut ecosystems is an important area of study that impacts on the use of additives and is related with several pathologies. Kefir is a fermented milk drink made with a consortium of yeast and bacteria as a fermentation starter, of which the use as additive in companion and livestock animals has increased in the last few years. To investigate the effect of kefir milk on foregut and hindgut digestive systems, an in vitro approach was followed. Either rumen fluid or horse fecal contents were used as a microbial inoculate and the inclusion of kefir (fresh, autoclaved, or pasteurized) was tested...

Small heat shock proteins (sHSPs) constitute a large, diverse, and functionally uncharacterized family of heat shock proteins. To gain insight regarding the function of sHSPs in insects, we identified genes encoding two sHSPs, Cshsp22.9b and Cshsp24.3, from the rice pest Chilo suppressalis. The cDNAs of Cshsp22.9b and Cshsp24.3 encoded proteins of 206 and 216 amino acids with isoelectric points of 5.79 and 9.28, respectively. Further characterization indicated that both Cshsp22.9b and Cshsp24.3 lacked introns...

INTRODUCTION: Some patients require one or more reoperative interventions after undergoing primary antireflux surgery (ARS). We compared outcomes after primary and reoperative ARS. METHODS: We queried a prospectively maintained database to identify patients who underwent ARS from September 23, 2003 to May 28, 2016. Patients were categorized into four groups: A (primary ARS), B (first reoperative ARS), C (second reoperative ARS), or D (≥ third reoperative ARS)...

Despite the wide variety of adaptive modifications in the oral and facial regions of vertebrates, their early oropharyngeal development is considered strictly uniform. It involves sequential formation of the mouth and pharyngeal pouches, with ectoderm outlining the outer surface and endoderm the inner surface, as a rule. At the extreme anterior domain of vertebrate embryos, the ectoderm and endoderm directly juxtapose and initial development of this earliest ecto-endoderm interface, the primary mouth, typically involves ectodermal stomodeal invagination that limits the anterior expansion of the foregut endoderm...

Transmission of plant viruses by phytophagous hemipteran insects encompasses complex interactions underlying a continuum of processes involved in virus acquisition, retention and inoculation combined with vector feeding behavior. Here, we investigated the effects of dietary pH on whitefly (Bemisia tabaci) feeding behavior and release of Lettuce infectious yellows virus (LIYV) virions retained in the vector's foregut. Electrical penetration graph analysis revealed that variables associated with whitefly probing and ingestion did not differ significantly in pH (4, 7...

BACKGROUND AND AIMS: Complications such as need for bowel resections and hospitalization due to Crohn's disease (CD) occur when disease activity persists due to ineffective therapy. Certain "high-risk" features require an early introduction of anti-tumor necrosis factor-α therapy to prevent such complications. We aim to evaluate the prevalence of "high-risk" features among a cohort of patients with CD and examine the association between discordance of early therapy with baseline risk stratification and disease outcome...

INTRODUCTION: Various reconstructions of the gastro-intestinal tract have been described in the past after distal gastrectomy. Among these, a Billroth II (BII) anastomosis can be performed with the addition of the Omega entero-enterostomy that may theoretically reduce the alkaline reflux. Given the significant complications associated with this procedure such as biliary reflux, marginal ulceration, and afferent loop syndrome, a revision into a Roux-en-Y anatomy is generally recommended...

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...
