BACKGROUND: Preterm infants' meals typically progress to higher volumes over time. Knowledge of gastric emptying (GE) responses to differing meal volumes may inform enteral feeding management. We examined the effect of meal volume and composition on preterm GE. METHODS: Forty infants were studied at 33.3±1.4 (29.7-35.6) weeks postmenstrual age when fully enteral fed (target 150 ml/kg/day). Intra-individual comparisons of GE were made for paired meals of 100 and 75% prescribed volume and identical composition of mother's own milk (n=21) and pasteurized donor human milk (n=19)...

Abnormal thickened lesions of the gastric wall are usually covered with normal mucosa. Conventional endoscopic biopsies often do not yield sufficient positive histological results for clinical treatment. To increase the rate of diagnosis of conventional endoscopic biopsy-negative gastric wall thickening, we used an endoscopic submucosal dissection (ESD)-like sampling method under endoscopic ultrasound (EUS) guidance to obtain tissue of gastric wall-thickening lesions. Between 2012 and 2016, patients with gastric wall thickening (as identified by computed tomography (CT), EUS or other imaging methods that showed no positive findings in repeating conventional endoscopic biopsy) underwent via mucosa incision EUS-guided sampling...

Vincent Zimmer
Gastroduodenal stenting using self-expandable metallic stents (SEMSs) represents a viable endoscopic option for palliative treatment of gastric outlet obstruction (GOO), less invasive relative to surgical and/or endoscopic ultrasound-guided gastroenterostomy (EUS-GE). Nevertheless, high rates of stent dysfunction remain a significant Achilles' heel of the procedure. Endoscopic removal of a distally migrated gastroduodenal stent remains challenging with single-channel techniques, calling for individually tailored solutions vis-à-vis the inevitable upstream stricture...

BACKGROUND: Perioperative aspiration leads to significant morbidity and mortality. Standard fasting periods are used to ensure an empty stomach in patients. Anesthesiologists are frequently confronted with cases of dubious adherence to these guidelines. Point-of-care gastric ultrasound is a diagnostic tool that offers information on the type and volume of gastric contents. METHODS: We performed a retrospective analysis of a departmental database containing clinical and sonographic information on elective surgical patients who had been non- compliant to the fasting guidelines...

Functional regurgitation (FR) is common in early infancy and represents a major drain on healthcare resources. This double-blind, randomized controlled trial investigated the effects of a formula containing partially hydrolysed, 100% whey protein, starch and Lactobacillus reuteri (DSM 17938) on gastric emptying rate (GErate) and regurgitation frequency in infants with FR. Enrolled infants were randomly allocated to receive either the test formula or a standard starter formula for four weeks. Ultrasound GErate assessment was performed at baseline (week 0) and at week 4; the number of regurgitations, feed volumes and potential adverse events were recorded in a daily diary...

BACKGROUND: Gastric accommodation to a meal may be important in the pathogenesis of upper gastrointestinal disorders, but has been difficult to investigate in a minimally invasive fashion. METHODS: We studied gastric and lower esophageal physiology during food intake, combining transabdominal ultrasound, multichannel high-resolution impedance-manometry (HRIM) and a symptom questionnaire. A HRIM catheter was distally positioned at incisura angularis and 300 mL saline with 75 g glucose was ingested...

BACKGROUND: Morbidly obese patients are at increased risk for venous thromboembolism (VTE) after bariatric surgery. Perioperative chemoprophylaxis is used routinely with bariatric surgery to decrease the risk of VTE. When bleeding occurs, routine chemoprophylaxis is often withheld due to concerns about inciting another bleeding event. We sought to evaluate the relationship between perioperative bleeding and postoperative VTE in bariatric surgery. METHODS: The American College of Surgeons-National Surgical Quality Improvement Program (NSQIP) dataset between 2012 and 2014 was queried to identify patients who underwent bariatric surgery...

Gastric submucosal tumors (SMTs) less than 2 cm are generally considered benign neoplasms, and endoscopic observation is recommended, but SMTs over 2 cm, 40% of which are gastrointestinal stromal tumors (GISTs), have malignant potential. Although the Japanese Guidelines for GIST recommend partial surgical resection for GIST over 2 cm with malignant potential as well as en bloc large tissue sample to obtain appropriate and large specimens of SMTs, several reports have been published on tissue sampling of SMTs, such as with endoscopic ultrasound sound fine needle aspiration, submucosal tunneling bloc biopsy, and the combination of bite biopsy and endoscopic mucosal resection...

Radiofrequency ablation (RFA) is a well-established treatment for several benign, pre-malignant, and malignant disorders. Although the role of RFA has been clearly defined, new indications for luminal and extra-luminal applications of endoscopic RFA-directed therapies have emerged. RFA has recently produced promising results in patients with a variety of gastrointestinal and hepatopancreatobiliary pathologies. For example, endoscopic RFA has been used to treat patients with gastric antral vascular ectasia, chronic radiation proctitis, malignant biliary strictures, and ampullary adenomas with intraductal extension...

Background: Current fasting guidelines allow oral intake of water up to 2 h before induction of anaesthesia. We assessed whether gum chewing affects gastric emptying of 250 ml water and residual gastric fluid volume measured 2 h after ingestion of water. Methods: This prospective randomized observer-blind crossover trial was performed on 20 healthy volunteers who attended two separate study sessions: Control and Chewing gum (chlorophyll flavour, with 2.1 g carbohydrate)...

Background: Pre-operative fasting balances safety against patient discomfort. We compared the gastric emptying profiles of a novel clear, high protein drink against a "traditional" clear and a non-clear fluid. Methods: We conducted a prospective cross-sectional study with 48 healthy volunteers, eight to 14 yr of age, fasted overnight and without risk factors for abnormal gastrointestinal motility. Subjects were randomized in equal ratio to ingest 296 ml of apple juice, 2% milk or Ensure Clear...

Purpose of Review Gastrointestinal stromal tumors (GISTs) are both relatively common. Management of these lesions has been challenging with emerging interest in the endoscopic approach for both diagnostic and therapeutic interventions. Recent Findings Although these can be visualized on CT scan, endoscopic ultrasound (EUS) represents the standard method of evaluation and characterization using fine needle aspiration cytology (FNA) when indicated. While EUS-FNA can yield diagnostic cells, full characterization requires a sufficient volume of viable cells to do molecular analysis for c-KIT and determine the mitotic index...

Rapunzel syndrome is a rare form of gastric trichobezoar (hair ball) involving extension of a tail of the hair into the small bowel. A 13-year-old girl was admitted with a 4-day history of epigastric pain and nausea which worsened after meals. Abdominal ultrasound showed duodenal wall thickening and lymphadenopathy. Esophagogastroduodenoscopy identified a gastric trichobezoar with a tail extending into the duodenum. In addition, multiple longitudinal duodenal and jejunal ulcers were noted. The ulcers appeared to be a result of direct pressure by the tail itself against the intestinal mucosa...

This paper discusses variations of laparoscopic transgastric cystogastrostomy in management of retrogastric pancreatic pseudocysts for 8 patients with symptom or pseudocysts (larger than 6 cm) companied with clinical manifestations. Using a Harmonic scalpel, two 3-5-cm incisions were made in the anterior and posterior gastric wall respectively. In the last step, the anterior gastrotomy was closed with an Endo-GIA stapler. All cases were successfully treated without large blood loss and without conversion to open surgery...

Rapunzel syndrome is a rare form of gastric trichobezoar. A 4-year-old girl presented with generalised oedema and an epigastric mass. Her family was of a relatively low socio-economic background. There was microcytic hypochromic anaemia, hypoalbuminaemia and an elevated α1-antitrypsin clearance. Abdominal ultrasound and non-contrast computed tomography demonstrated a heterogeneous mass related to the stomach. Upper gastro-intestinal tract endoscopy failed to remove it. Surgical laparotomy was undertaken through a single anterior gastrotomy incision and a large mass was extracted which was a cast of the duodenum and stomach and had a tail of approximately 60 cm in length which extended to the jejunum...

Gastric glomus tumors are extremely rare, constituting approximately 1% of gastric mesenchymal tumors. We report the case of a 45-year-old female patient in whom upper gastrointestinal endoscopy revealed a 3-cm submucosal tumor with a bridging fold in the posterior wall of the antrum of the stomach. Contrast-enhanced computed tomography revealed the tumor to be hypervascular in the arterial phase and exhibit continuous enhancement in the post-venous phase. Dynamic contrast-enhanced magnetic resonance imaging showed that the tumor was hypervascular in the early phase and persistently enhanced in the late phase...

BACKGROUND: Gastric residuals are a common finding in enterally fed preterm neonates and traditionally thought to reflect immaturity-related delayed gastric emptying. Adult human data suggest that the meal volume regulate the gastric emptying rate, but early in life, this has not been adequately evaluated. The goal of this study was to study the rat postnatal changes in gastric emptying rate and the strain-induced effect on muscle contraction. We hypothesized that the stomach content volume and not developmental factors determines the newborn gastric emptying rate, via the Rho-kinase 2 (ROCK-2) pathway...

Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community...
