Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD...

The experience of the "endoscopic community" in pediatric patients is limited, but during recent years increased skills of the endoscopists and technological improvements lead to a standardization of pediatric endoscopy and the development of specialized pediatric endoscopy unit. Adverse events related to diagnostic and therapeutic endoscopy in children are usually rare. Diagnosis, prevention and treatment of complications in pediatric endoscopy is crucial when dealing with benign diseases in children. The complication rate of diagnostic EGD and colonoscopy in children are extremely low...

Submucosal endoscopy essentially regroups peroral endoscopic esophageal myotomy (POEM) and, more recently, pyloromyotomy and tunnel tumor resections. The complication rate of POEM is between 5% and 10%. Complications include gas-related complications, mucosal tears, and bleeding, and are usually managed conservatively or with non-surgical procedures. Only one case of death has been reported. The most commonly identified risk factors for complicated procedures in POEM are short experience with the technique and sigmoid-type esophagus...

BACKGROUND: α1-Antitrypsin deficiency (ATD) is the most common genetic cause of liver injury in young children. Asymptomatic hepatitis is observed in most patients. However, the course of liver disease due to ATD is unpredictable, and some children develop liver cirrhosis. Liver transplantation (Ltx) dramatically improves their outcome and in some cases is required in the first years of life. The aim of the study was to evaluate the course of the disease in children with ATD treated with Ltx in a single center...

Although oral gavage is the most straightforward approach to achieve precise enteric administration in rodents, it is associated with potential adverse consequences. Here we compare the effects of serial oral gavage in awake compared with anesthetized mice. Female C57BL/6J mice (n = 20 per group) were assigned to 1 of 3 treatment groups (control, awake gavage, or anesthetized gavage) and gavaged daily with 0.2 mL of saline (with no manipulation on weekends) for a total of 18 treatment days. Body weight and clinical appearance were monitored throughout the treatment period, after which mice were euthanized and necropsied...

The ingestion of cell batteries can cause serious complications (fistula, perforation or stenosis) at the esophageal level. The damage starts soon after ingestion (approximately 2 hours) and is directly related to the amount of time the battery is lodged in said location, the amount of electrical charge remaining in the battery, and the size of the battery itself. Injury is produced by the combination of electrochemical and chemical mechanisms and pressure necrosis. The ingestion of multiple cells and a size > = 20 mm are related with more severe and clinically significant outcomes...

RATIONALE: Ingestion of a fishbone is a common cause of esophageal injury, but spinal epidural abscess (SEA) is a rare condition due to the esophageal penetration by a swallowed fishbone. Prompt diagnosis can be seldom made owing to incomplete patient history taking and difficulties in imaging evidence identification. PATIENT CONCERNS: We describe the case of a 62-year-old woman who was stuck in her throat by a fishbone, and complained of back pain, paresis of the lower limbs and fever, successively...

BACKGROUND: Esophageal fully covered self-expandable metal stents (FCSEMS) are indicated for the management of benign and malignant conditions of the esophagus including perforations, leaks, and strictures. FCSEMS are resistant to tissue ingrowth and are removable; however, stent migration occurs in 30-55% of cases. Endoscopic suture fixation of FCSEMS has been utilized to decrease the risk of stent migration though data supporting this practice remain limited. The primary aim of this study was to compare clinical outcomes and migration rate of patients who underwent placement of esophageal FCSEMS with and without endoscopic suture fixation...

OBJECTIVES: Endoscopic submucosal dissection (ESD) is a more difficult technique for esophageal cancer than for gastric cancer because the working space for esophageal ESD is small. Further, the difficulty level gradually increases depending on the size of the carcinoma. To overcome these difficulties, double endoscopic intraluminal operation (DEILO), which enables the resection of mucosal lesions using two fine endoscopes and monopolar shears, was reported previously. Here, we report the utility of DEILO for esophageal cancer...

BACKGROUND: Despite the lack of long-term results, peroral endoscopic myotomy (POEM) has been increasingly propagated as a feasible alternative to pneumatic balloon dilatation (BD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. After a long-term follow-up, a large percentage of patients reported recurrence of dysphagia. It is unclear which kind of procedure (redo POEM or LHM) should be utilized in these patients with failed POEM. CASE REPORT AND RESULTS: We report the case of a 37-year-old female patient with type I achalasia who was successfully treated with LHM after a failed POEM procedure...

The aim of this study was to evaluate the antioxidant and antiproliferative activities of PSO in vitro and its application in horse oil storage. We determined the reducing power of PSO and its scavenging effects on hydroxyl (•OH) and 1,1-diphenyl-2-picrylhydrazyl radicals (DPPH•) and tested its stabilizing effects on horse oil storage. The results showed that PSO had remarkable, dose-dependent antioxidant activities, and it effectively prevented horse oil lipid oxidation. We treated cervical cancer HeLa cells, esophageal cancer Eca-109 cells and breast cancer MCF-7 cells with PSO using non-neoplastic monkey kidney Vero cells as controls...
