Carolina Malagelada, Juan R Malagelada
PURPOSE OF REVIEW: Small bowel motility disorders constitute a relatively small but important segment of clinical gastroenterology. Presenting features encompass a broad range of symptom manifestations and severity: from chronic functional-type complaints to life-threatening nutritional impairment. Diagnostic assessment of patients with suspected intestinal motility disorders is often hampered by the complexity of measuring intestinal contractile activity in humans. In this review, we describe and critically comment the main current and forthcoming methodologies...

Dalbir S Sandhu, Ronnie Fass
Gastroesophageal reflux disease (GERD) defined as heartburn and/or regurgitation is one of the most common gastrointestinal disorder managed by gastroenterologists and primary care physicians. There is an increase in GERD prevalence since 1995 particularly in North America and East Asia. Over the past three decades proton pump inhibitors (PPIs) had become the mainstay medical therapy for management of GERD. However, over the last decade there is an increasing awareness amongst physicians and patient population regarding the side effects of otherwise considered safe PPIs...

BACKGROUND: The necessity for reoperation due to insufficient weight loss after bariatric surgery has led to a novel endoluminal plication of the gastric sleeve using a endoscopic suturing device. Advances in endoluminal endoscopy and other minimally invasive bariatric surgeries have inspired innovative techniques and have produced reliable suturing tools for gastric volume reduction. METHODS: Retrospective pilot case series of 5 patients with an enlarged gastric sleeve...

Obesity is a growing problem in developed countries, and surgery is the most effective treatment in terms of weight loss and improving medical comorbidity in a high proportion of obese patients. Despite the advances in surgical techniques, some patients still develop acute and late postoperative complications, and an endoscopic evaluation is often required for diagnosis. Moreover, the high morbidity related to surgical reintervention, the important enhancement of endoscopic procedures and technological innovations introduced in endoscopic equipment have made the endoscopic approach a minimally-invasive alternative to surgery, and, in many cases, a suitable first-line treatment of bariatric surgery complications...

BACKGROUND: With the increasing frequency of tunneled hemodialysis catheter use there is a parallel increase in the need for removal and/or exchange. A small but significant minority of catheters become embedded or 'stuck' and cannot be removed by traditional means. Management of embedded catheters involves cutting the catheter, burying the retained fragment with a subsequent increased risk of infections and thrombosis. Endoluminal dilatation may provide a potential safe and effective technique for removing embedded catheters, however, to date, there is a paucity of data...

BACKGROUND: Endoscopy is useful in assessing conduit ischemia and anastomotic leaks after esophagectomy but poses a theoretical threat of anastomotic disruption. We used a porcine model to evaluate the safety of endoscopy after esophagectomy. METHODS: We performed esophagectomies in 10 live pigs and performed endoscopy with progressive air insufflation and continuous intraluminal pressure monitoring. We stopped insufflation when the intraluminal pressure reached a plateau...

The small bowel is a prime target for bariatric and metabolic endoscopic therapies. New insights into the mechanisms of action of surgical therapies have led to new endoscopic therapies for obesity, type 2 diabetes mellitus, and the metabolic syndrome. The development of endoluminal sleeves that bypass the proximal duodenum have replicated some of the effects of surgical bypass procedures. The endoscopic dual-path enteral bypass has created new and treatment options for these conditions. Duodenal mucosal resurfacing offers significant promise for diabetes management...

Bariatric surgical procedures, including gastric bypass, vertical sleeve gastrectomy, and biliopancreatic diversion, are the most effective and durable treatments for obesity. In addition, These operations induce metabolic changes that provide weight-independent improvement in type 2 diabetes, fatty liver disease and other metabolic disorders. Initially thought to work by mechanical restriction of food intake or malabsorption of ingested nutrients, these procedures are now known to work through complex changes in neuroendocrine and immune signals emanating from the gut, including peptide hormones, bile acids, vagal nerve activity, and metabolites generated by the gut microbiota, all collaborating to reregulate appetite, food preference, and energy expenditure...

The study's objective was to determine effects of relative size and placement location of endoluminal stents on incidence of complications and survival for canine tracheal collapse. Measurements were obtained on lateral radiographs before and after stenting to determine percent of the trachea occupied by the stent. These values were monitored over time and compared to complication rates and survival. Overall median survival time was 502 days. Six month survival rate was 78%, 1 yr survival was 60%, and 2 yr survival was 26%...

Heterotopic pancreas is a congenital anomaly in which pancreatic tissue is anatomically separate from the main gland. The most common locations of this displacement include the upper gastrointestinal tract-specifically, the stomach, duodenum, and proximal jejunum. Less common sites are the esophagus, ileum, Meckel diverticulum, biliary tree, mesentery, and spleen. Uncomplicated heterotopic pancreas is typically asymptomatic, with the lesion being discovered incidentally during an unrelated surgery, during an imaging examination, or at autopsy...

Bio-kinetic thrombus dissolution model has been developed to describe the thrombus dissolution behavior during endoluminal thrombolytic patch treatment to recanalize blocked vessel in ischemic strokes. The initial model ignored the effect of pulsatile pressure in the lumen. However, pulsatile pressure in the lumen may affect molecule diffusion and bio-chemical reaction rate and accelerate clot dissolution. The effect of pressure on the dissolution rate was examined in this study. The dissolution behaviors of 100-400 μm thick blood clot specimens subject to diastolic, systolic, and pulsatile pressure were characterized using Raman spectroscopy...

BACKGROUND: Isolated congenital diaphragmatic hernia defect allows viscera to herniate into the chest, competing for space with the developing lungs. At birth, pulmonary hypoplasia leads to respiratory insufficiency and persistent pulmonary hypertension that is lethal in up to 30% of patients. Antenatal measurement of lung size and liver herniation can predict survival after birth. Prenatal intervention aims at stimulating lung development, clinically achieved by percutaneous fetal endoscopic tracheal occlusion under local anesthesia...

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) has become a widely accepted option in the treatment of morbid obesity. Gastric leaks after SG occur in .9%-2.2% of the patients, mostly at the gastroesophageal junction. The current treatment algorithm includes drainage, antibiotics, nutritional support, and endoluminal control. OBJECTIVES: Our hypothesis is that long, fully covered stents represent a safe, effective solution for SG leaks. SETTING: University hospital...

The term "stuck catheter" refers to situations where a central venous catheter cannot be removed from the central veins or right atrium using standard technique, usually due to development of a fibrin sheath leading to adherence to SVC or right atrial wall. Endoluminal dilatation is an interventional radiology technique that has been previously reported in the removal of stuck hemodialysis catheters, and to the best of our knowledge, this case describes the first application of the technique to remove a hemodialysis catheter that was adherent to SVC wall and transvenous pacemaker leads...
