Esophageal balloon

Esophageal cancer is the seventh most common type of cancer and the sixth leading cause of cancer -related mortality worldwide. Endoscopic submucosal dissection (ESD) is widely used for the resection of early esophageal cancer. However, post-ESD esophageal stricture is a common long-term complication, which requires attention. Patients with post-ESD esophageal stricture often experience dysphagia and require multiple dilatations, which greatly affects their quality of life and increases healthcare costs. Therefore, to manage post-ESD esophageal stricture, researchers are actively exploring various strategies, such as pharmaceutical interventions, endoscopic balloon dilation, and esophageal stenting...

Esophageal atresia (EA) repair can be complicated by associated malformations such as a tracheobronchial remnant in the distal esophagus. We describe our experience with a patient found to have long-gap EA with a distal cartilaginous ring who was managed using a combination of esophageal lengthening and magnetic compression anastomosis. A 5-month-old girl was referred to us from an outside hospital with type C EA including a very high upper pouch. She had undergone a prior thoracotomy with fistula ligation during which a clip was placed on the lower esophagus, leaving a 2-cm diverticulum on the trachea and a short lower esophageal pouch...

An 80-year-old woman with a history of left breast cancer complained of dysphagia. At the age of 67 years, she had undergone a left modified radical mastectomy, chemotherapy, and endocrine therapy for left breast cancer. Six years after adjuvant therapy completion, she developed dysphagia. Chest CT showed only midesophageal stenosis. Endoscopic examination revealed whole circumferential stenosis without mucosal abnormality located 25 cm from the incisors, and a biopsy showed histologically normal mucosa. Endoscopic balloon dilatation was performed 5 times in 1 year and 3 months...

Most patients with benign esophageal stenosis require multiple or even continuous balloon dilation treatments to achieve symptom relief. In this study, eighteen rabbits were used to establish an esophageal benign stenosis model and were divided into a control group (n = 6), a balloon group (n = 6) and a PTX-coated balloon group (n = 6) to evaluate the feasibility and effectiveness of paclitaxel (PTX)-coated balloons for the rabbit esophageal benign stenosis model. The weight and esophageal diameter were recorded every 2 weeks until 8 weeks post-surgery...

Endoluminal functional lumen impedance planimetry (EndoFLIPTM ) has become the gold standard to evaluate esophageal distensibility, although the study itself and its analysis present challenges. We propose here a new method to assess lower esophageal distension capacity that overcomes several limitations of prior approaches, including incomplete and corrupted EndoFLIPTM recordings. Esophageal distension capacity was evaluated with a 16-channel EndoFLIPTM in 10 controls and 14 patients with eosinophilic esophagitis (EoE)...

BACKGROUND: There is no optimal reconstruction method after proximal gastrectomy. The valvuloplastic esophagogastrostomy can reduce postoperative reflux esophagitis, but it is technically complex with a long operation time. The gastric tube anastomosis is technically simple, but the incidences of reflux esophagitis and anastomotic stricture are higher. METHODS: We have devised a modified valvuloplastic esophagogastrostomy after laparoscopy-assisted proximal gastrectomy (LAPG), the arch-bridge anastomosis...

Achalasia is an esophageal motility disorder characterized by loss of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter. Patients with achalasia often complain of persistent symptoms for several years before diagnosis. On the other hand, achalasia diagnosed as a sudden esophageal food impaction is uncommon, and no report has been issued on the diagnosis and successful treatment of achalasia in a 95-year-old patient. We report a case of achalasia diagnosed by high-resolution esophageal manometry and timed barium esophagography after food material removal by endoscopy in a 95-year-old woman who visited the hospital due to sudden esophageal food impaction and was successfully treated by endoscopic balloon dilatation...

Background: Acute esophageal variceal bleeding accounts for up to 70% of upper-gastrointestinal bleeding in cirrhotic patients. About 10-20% of patients with acute variceal bleeding have refractory bleeding that is not controlled by medical or endoscopic therapy, and this condition can be life-threatening. Balloon tamponade is a long-standing therapy which is only effective temporarily and has several complications, while transjugular intrahepatic portosystemic shunt (TIPS) and liver transplantation may not be readily available at some centers...

Background : Although bleeding from gastric varices is less observed than esophageal variceal bleeding (VB) (25% vs. 64%), it is associated with an exceedingly high mortality rate of up to 45%. Current guidelines suggest that endoscopic cyanoacrylate injection therapy (ECI) is the first-line treatment for gastric variceal bleeding (GVB). A major concern, however, is the possibility of embolic incidents, which are clinically evident in approximately 1% of cases. There are no guidelines for secondary prophylaxis of GVB...

BACKGROUND: Methods to prevent esophageal stenosis (ES) after endoscopic submucosal dissection (ESD) for superficial esophageal squamous cell carcinoma (ESCC) have received increasing attention. Although steroid administration is a prophylactic treatment, the risk factors for ES during prophylactic steroid therapy remain unknown. Therefore, this study aimed to retrospectively evaluate the risk factors for refractory ES in patients administered prophylactic steroids after ESD for ESCC...

Endoscopic submucosal dissection (ESD) has been widely used in the early neoplasia of the esophagus. However, postoperative esophageal stenosis is a big problem, particularly when a large circumferential proportion of esophageal mucosa is resected. Currently, there are several methods available to prevent esophageal stenosis after ESD, including steroid administration, esophageal stent implantation, and endoscopic balloon dilation (EBD). However, the therapeutic effects of these are not yet satisfactory. Stem cell-based therapies has shown promising potential in reconstructing tissue structure and restoring tissue function...

Esophageal cancer is typically identified as squamous cell carcinoma or adenocarcinoma. There are multiple risk factors that may contribute to esophageal squamous cell carcinoma including smoking, alcohol consumption, and the human papillomavirus. Lesions may appear ulcerated, friable, and circumferential and may obstruct the esophagus. Therefore, patients may complain of non-specific symptoms including dysphagia, weight loss, and retrosternal discomfort. Clinicians often rely on an upper endoscopy with biopsy to confirm the diagnosis...

BACKGROUND: Accuracy of esophageal pressure measured by an air-filled esophageal balloon catheter is dependent on balloon filling volume. However, this has been understudied in mechanically ventilated children. We sought to study the optimal filling volume in children receiving ventilation by using previously reported calibration methods. Secondary objectives included to examine the difference in pressure measurements at individualized optimal filling volume versus a standardized inflation volume and to study if a static hold during calibration is required to identify the optimal filling volume...

Acute respiratory distress syndrome (ARDS) is characterized by the heterogeneous distribution of lung aeration along a gravitational direction due to increased lung density. Therefore, the lung available for ventilation is usually limited to ventral, nondependent lung regions and has been called the "baby" lung. In ARDS, ventilator-induced lung injury is known to occur in nondependent "baby" lungs, as ventilation is shifted to ventral, nondependent lung regions, increasing stress and strain. To protect this nondependent "baby" lung, the clinician targets and limits global parameters such as tidal volume and plateau pressure...

BACKGROUND AND AIM: Managing gastric variceal (GV) hemorrhage is more complicated than managing esophageal variceal (EV) bleeding, resulting in significantly higher morbidity and mortality. We aim to compare the outcomes of endoscopic variceal ligation (EVL), transhepatic intrahepatic portosystemic shunt (TIPS), and balloon-occluded retrograde transvenous obliteration (BRTO) in the management of GV bleeding. METHODS: We utilized the National Inpatient Sample (NIS) database from January 2016 to December 2019 to include adult patients with GV hemorrhage...

Solitary Peutz-Jeghers-type polyp (SPJP) is a rare hamartomatous lesion. It is considered a different entity from Peutz-Jeghers syndrome despite similar histopathological findings. It can be found in the GI tract but rarely in the jejunum. Jejunal SPJP is susceptible to necrosis, ulceration, and intussusception, resulting in GI bleeding or small bowel obstruction. We describe a case of subacute gastrointestinal bleeding secondary to jejunal SPJP to share our approach to this challenging case using therapeutic endoscopy...

BACKGROUND: Standard impedance catheters and balloon-based mucosal impedance catheters (BBMI) have been used to assess mucosal integrity and diagnose mucosal diseases. The goal of this study was to determine the age-related technical issues associated with mucosal balloon inflation, validate the BBMI measurement against a standard impedance probe, and compare software-generated diagnoses to histologic diagnoses. METHODS: We prospectively recruited patients undergoing endoscopy, during which patients underwent standard mucosal impedance catheters and BBMI measurements...

When performing endoscopic submucosal dissection (ESD) beyond stenoses, there have only been two choices: balloon dilation until a conventional therapeutic endoscope passes through or the use of an ultrathin endoscope. However, balloon dilation has a risk of perforation and an ultrathin endoscope limits the devices that may be used. The novel thin-therapeutic endoscope has an outer diameter of 7.9 mm and instrument channel diameter of 3.2 mm; therefore, there are no restrictions on the ESD device that may be used, and the procedure may be performed in the same manner as regular ESD...

Background and study aims Foreign body ingestion is a common cause for Emergency Department presentation. In adults, foreign body ingestion is more common in patients with underlying psychiatric comorbidity, the elderly, alcohol intoxication, and in prisoners. This study reviewed the management of patients presenting to a tertiary hospital with foreign body ingestion. Patients and methods A retrospective review of patients presenting with foreign body ingestion to a tertiary hospital in Melbourne, Victoria, was undertaken from January 2017 to December 2021...
