Time pattern of gastric acidity in Barrett's esophagus.
1996
Increased gastroesophageal acid reflux is frequently found in patients with Barrett's esophagus, and it has been hypothesized that gastric acid hypersecretion could be an important factor aggravating the exposure of esophageal mucosa to acid and then contributing to the development of this disorder. The aim of the present study was to assess whether the circadian pattern of gastric acidity differs between refluxer patients with and without Barrett's esophagus and normal subjects. Continuous 24-hr gastric pH monitoring was performed in 119 healthy volunteers, 20 patients with Barrett's esophagus, 37 patients with moderate and 10 patients with severe reflux esophagitis without Barrett's esoph…
Perforated giant mycotic aneurysm of mitral valve in a drug-addicted young man: Rare complication of infective endocarditis
2017
Infective endocarditis (IE) affects patients at high clinical risk and may present as an acute and rapidly progressive, subacute or chronic infection. Transthoracic and transesophageal echocardiography represent the key diagnostic method in IE diagnosis. In particular, three-dimensional transesophageal echocardiography represents the imaging technique that allows to establish with adequate accuracy dimensions, shape, and localization of endocarditis vegetations. In our case, we show a huge vermiform mycotic aneurysm in an immunodeficient young drug-addicted man with severe mitral valve regurgitation and the additive value of three-dimensional transesophageal echocardiography in this specifi…
Using multidimensional scaling in model choice for congenital oesophageal atresia: similarity analysis of human autopsy organ weights with those from…
2020
Swine models had been popular in paediatric oesophageal surgery in the past. Although being largely replaced by rodent models, swine experienced a revival with the establishment of minipig models. However, none of them has ever been investigated for similarity to humans. We conducted a pilot study to determine whether three-week old Pietrain piglets and three-month old Aachen Minipigs are suitable for experimental paediatric oesophageal atresia surgery. We tested the operation's feasibility, performed a necropsy, weighed organs, measured organ length and calculated relative weights and lengths, and measured laboratory parameters. We used multidimensional scaling to assess the similarity of…
Aortic intramural hemorrhage visualized by transesophageal echocardiography: Findings and prognostic implication
1994
Abstract Objectives. This study describes the transesophageal echocardiographic and follow-up findings in patients with aortic intramural hemorrhage. Background. Localized aortic intramural hemorrhage resulting in layered thickening of the aortic wall seems to represent a variant of acute aortic dissection without communication or a typical moving intimal flap. In autopsy studies this variant, attributed to a rupture of the van vasorum, has been described in 5% to 10% of patients with dissection. Methods. In a prospective transesophageal echocardiographic study in patients with aortic dissection performed between 1986 and 1991, the diagnosis of intramural hemorrhage was established in 15 of…
Gastroesophageal reflux in patients treated for congenital diaphragmatic hernia: short- and long-term evaluation with multichannel intraluminal imped…
2013
The incidence of GER, related symptoms and complications in patients treated for congenital diaphragmatic hernia (CDH) are poorly defined. The aim was to evaluate incidence and development of GER in children treated for CDH in a short- and long-term follow-up period, identifying potential risk factors of morbidity. Thirty-six patients were evaluated with pH-MII at a median age of 6 months (T1) and re-evaluated with pH-MII and endoscopy at a median age of 5 years (T2). The incidence of reflux was 83 % in T1 and 61 % in T2; the incidence of symptoms was 62 % in T1 and 38 % in T2. In both groups the reflux was mainly non-acidic. Patch, intrathoracic stomach and esophageal dysmotility were risk…
Long-term results of photodynamic therapy with 5-aminolevulinic acid for superficial Barrett's cancer and high-grade intraepithelial neoplasia
2005
Photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) has proven to be safe and effective in patients with early neoplasia in Barrett's esophagus. However, long-term results in patients with high-grade intraepithelial neoplasia (HGIN) or with early cancer are still lacking.The aim of the study was to evaluate the efficacy of ALA-PDT and the survival of patients with early Barrett's neoplasia. ALA-PDT was carried out in 66 patients. Protoporphyrin IX induced by oral administration of ALA (60 mg/kg body weight orally applied 4-6 hours before PDT) was used as the photosensitizer. Acid suppression was maintained in all patients.Between September 1996 and September 2002, 667 patients with …
Successful Endoscopic Resection of an Esophageal Metastasis from a Preceding Squamous-Cell Tonsillar Carcinoma
2005
This report describes the case of a 62-year-old man with tonsillar carcinoma who had undergone esophagectomy due to an esophageal metastasis. Subsequently, a second metastasis occurred in the residual esophagus, and he presented for evaluation for local endoscopic therapy. The initial upper endoscopy revealed a type IIa - c lesion at 21 cm from the incisors, within a segment suspicious for Barrett's mucosa. As part of the complex treatment approach in this patient, endoscopic resection of the lesion was carried out using the suck-and-cut technique with ligation. Histology showed that the lesion was a metastasis from a squamous-cell carcinoma, with focal infiltration of the upper submucosal …
Laparoscopic resection of an epiphrenic diverticulum of the esophagus
2000
Diverticulectomy of epiphrenic diverticula of the esophagus is conventionally performed via left thoracotomy. We report the case of a 57-year-old man who presented with an epiphrenic diverticulum that was resected using a transperitoneal laparoscopic technique.
Embolic stroke, sinus rhythm and left atrial mechanical function
2004
A 64-year-old man manifested a stroke two years after restoration of sinus rhythm through a radiofrequency catheter ablation. Transesophageal echo- cardiography demonstrated the presence of a thrombus in the left atrial appendage. Left atrial volumes and different parameters of atrial emptying showed that, de- spite the persistence of the sinus rhythm, atrial mechanical function was severely impaired. After atrial ablation procedures echocardiography can be useful to stratify pa- tients according to their risk of developing embolic events and hence be of help in deciding whether or not discontinuation of anticoagulant therapy is the appropri- ate choice.
Evaluation of esophageal motility and reflux in children treated for congenital diaphragmatic hernia with the use of combined multichannel intralumin…
2011
Abstract Background Gastroesophageal reflux (GER) is frequently observed in children treated for congenital diaphragmatic hernia (CDH) at birth, as well as esophageal dysmotility, that has been hypothesized to be caused by innervatory anomalies. The aim of this study is to evaluate GER and dysmotility in young patients with CDH using pH-multichannel intraluminal impedance. Methods Thirty children (17 boys and 13 girls) who underwent repair for CDH between 2002 and 2007 with a median age of 5.2 years (range, 3-10 years) were included in the study. All patients were operated on with a subcostal laparotomy incision and had a left-sided diaphragmatic defect. The defect repair required an artifi…
