Die corner filling is very important in tube hydroforming process. Definition of the internal pressure path is a key factor in improving the corner filling.  However, the factors that cause improvement of corner filling are still unclear. In this paper, effect of bilinear pressure path on corner filling in hydroforming of tube in box-shape die is studied using both finite element simulation and...

A N infant delivered in a private hospital after 33 weeks’ gestation weighed 2,050 g, had persistent tachypnea, and had associated hypoxia requiring intubation. After three esophageal intubations, the neonate’s trachea was successfully intubated. Despite mechanical ventilation, the infant had persistent tachycardia, hypoxemia (80–90% oxygen saturation) and a distended abdomen. A preoperative ra...

Esophageal duplication cysts are infrequent anomalies of the gastrointestinal tract that are predominantly found in children. The conventional surgical approach for removal of these cysts is an open surgery one with a posterolateral thoracotomy incision. However, more recently, these cysts have been excised via video-assisted thoracoscopic surgery (VATS). In this article, we present 2 pediatric...

Feeding difficulties such as dysphagia, coughing, choking, or vomiting during meals, slow eating, oral aversion, food refusal, and stressful mealtimes are common in children with repaired esophageal atresia (EA) and the reasons for this are often multifactorial. The aim of this review is to describe the possible underlying mechanisms contributing to feeding difficulties in patients with EA and ...

BACKGROUND Esophageal perforation is a serious, but rare complication of high mortality following the endoscopic submucosal dissection (ESD) procedure. The aim of this study is to evaluate the efficacy and safety of nonsurgical treatment of esophageal perforations caused by ESD based on our clinical experience. METHODS From January 2009 to November 2013, 8 patients were diagnosed with endosco...

An exclusive right thoracic approach for esophagus surgery is rarely used, with few reports of its use in China. We retrospectively reviewed the data of 21 esophageal cancer patients from January 2010 to January 2015. Their age ranged from 74-83 years (average 76.6). All of the patients had lower pulmonary function. After multidisciplinary team discussion, sufficient preoperative preparation, a...

Background: Malnutrition dramatically increases the risk of postoperative complications and delays patient recovery. Therefore, a feeding jejunostomy tube (FJT) is routinely placed during esophagectomy to maintain nutrition supply. However, recently published studies have questioned need FJT in every esophageal cancer patient. Because most patients can resume oral intake shortly after surgery, ...

We present our own observation of the multidrug-resistant tuberculosis course case, complicated by esophageal-pulmonary fistula, in a palliative patient who was treated Pulmonary Tuberculosis Department No. 2 Zaporizhzhia Regional Phthisio-pulmonology Clinical Treatment and Diagnostic Center. An esophago-pulmonary fistula with detected area right upper lobectomy, wich perfomed 8.5 years ago. Th...

RATIONALE Congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) ininfants have been treated well with surgery. Approximately 10% of children displayed recurrent fistula. In the present case, we reported recurrent TEF in an adolescent as a complication of EA/TEF in infancy. PATIENT CONCERNS An infant was diagnosed with gross type C congenital EA and TEF and subsequentlyunderwe...

Carcinosarcoma of the esophagus is a malignant neoplasm involving both carcinomatous and sarcomatous components. We report a patient with true esophageal carcinosarcoma who underwent laparoscopy-assisted surgery. An upper gastrointestinal barium study revealed a lobulated intraluminal filling defect in the lower intrathoracic esophagus. The patient underwent esophagectomy and regional lymphaden...
