Endoscopic Ultrasonography in the Diagnosis of Regional Lymph Nodes in Esophageal and Gastric Cancer - Results of Studies in Vitro
1993
A total of 90 regional lymph nodes (43 benign/47 metastatic) from 16 surgical resection specimens of patients with esophageal and gastric carcinoma were examined in vitro by endosonography. The validity of endosonographic criteria of lymph node dignity (size, echogenicity, internal echo pattern and margin structure) was assessed using computer-supported B-mode analysis and compared to histopathological results. Of 26 lymph nodes with a diameter of more than 10 mm, 19 were metastatic (72%). The subjective assessment of the internal echo pattern (homogeneity) and the node margins by an experienced observer allowed the diagnosis of metastatic lymph nodes, but there was a high proportion of fal…
Chromoendoscopy in Barrett's oesophagus: is cresyl violet the magic bullet?
2006
The endoscopic detection of Barrett’s epithelium remains challenging even for modern endoscopy. This is mainly due to the fact that Barrett’s epithelium is often patchy and can easily be overlooked by conventional endoscopy with random biopsies. Thus, chromoendoscopy and magnifying endoscopy were introduced to facilitate diagnosis of Barrett’s epithelium and Barrett’s associated neoplasias. Methylene blue-aided chromoendoscopy was firstly introduced by Canto et al. [1]. The authors could show that methylene blue selectively stains specialised columnar epithelium, which is pathognomonic for Barrett’s epithelium. In contrast, dysplastic areas revealed no or weaker staining due to changes in t…
Extended pH-monitoring in the evaluation of gastroesophageal reflux in infancy and childhood
1986
Esophageal 24-h pH monitoring was performed in addition to esophagogastrography, esophageal manometry, and esophagoscopy in 66 infants and 12 children from 2–14 years of age with symptoms characteristic of gastroesophageal reflux (GER). In ten infants, ph monitoring was repeated once or twice at intervals of 1 week to 8 1/2 months. The follow-up time for all patients ranged from 2–7 years. Our findings suggest that extended pH monitoring is the most valuable diagnostic procedure under the following circumstances. First, when there are major discrepancies between reported observations and actual symptoms during hospitalization, pH monitoring can clarify the causal relationship. Second, when …
Reversible esophageal motor dysfunction in botulism
1985
Two cases of botulism with autonomic and neuromuscular system involvement are presented. In both patients, dryness of the mouth and difficulties in swallowing were predominant symptoms. Esophageal manometry revealed a marked decrease in peristaltic amplitude, which was most pronounced in the upper third of the esophagus. These functional abnormalities returned to normal following recovery from the acute disease.
A Continuous Suture Anastomosis Outperforms a Simple Interrupted Suture Anastomosis in Esophageal Elongation.
2020
Abstract Introduction Long-gap esophageal atresia represents a distinct entity among the esophageal atresia spectrum. In many patients, achieving a reasonable anastomosis depends on some millimeters of tissue. We aimed to determine what effect the suturing technique would have on esophageal ex vivo elongation as it may determine the strength of a primary anastomosis. Materials and Methods In an analysis of porcine esophagi from animals for slaughter (100–120 days old with a weight of 100–120 kg), we determined esophageal length gain of simple continuous and simple interrupted suture anastomoses subjected to linear traction until linear breaking strength was reached. Statistical power of 80%…
Beyond Magnamosis: A Method to Test Sutureless Esophageal Anastomotic Devices in Living Swine by Creating an Esophageal Bypass Loop for Natural Oral …

Abstract Introduction: Thoracoscopic esophageal atresia repair has become increasingly popular, but is still limited to a few expert centers and has some challenges and shortcomings. One of them ha...
Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays.
2021
Abstract Background Button battery ingestions have emerged as an increasing medical issue in recent years, especially for children. The frequent use of these energy sources in small appliances and toys is responsible for their ubiquitous occurrence in households. In addition to other possible foreign bodies, button batteries are particularly dangerous as they can cause severe complications in the aerodigestive tract. Objective The study aimed for a detailed analysis of specific radiographic identifiers of button batteries and similarly configured potential esophageal foreign bodies in high-resolution X-ray scans. Methods A selection of potentially hazardous button batteries - in cases of in…
Long-Segment Early Squamous Cell Carcinoma of the Proximal Esophagus: Curative Treatment and Long-Term Follow-Up after 5-Aminolevulinic Acid (5-ALA)-…
2006
Photodynamic therapy (PDT) is an established treatment for the ablation of dysplastic Barrett's epithelium and early esophageal carcinoma, but no data have been published on curative 5-aminolevulinic acid (5-ALA)-PDT for long-segment early esophageal cancer with infiltration of the upper sphincter. We describe successful curative treatment of an unusual early long-segment squamous cell carcinoma (uT1a,N0) of the proximal esophagus (18 - 28 cm aborally), with three sessions of 5-ALA-PDT. Endoscopic and endosonographic follow-up macroscopically showed a complete remission of the tumor, proven by biopsy showing total histological ablation. After a follow-up period of 23 months, there has been …
Achalasia with megaesophagus and tracheal compression in a young patient: A case report.
2015
Highlights • This report emphasizes that physicians should be alert and consider airway obstruction and signs of dyspnea as severe and threatening symptoms in extensive cases of achalasia with megaesophagus. • Early surgical treatment provides a therapeutic option to obviate the occurrence of acute respiratory distress and consecutive complications. • In particular, difficulties in intubation prior to surgery must be considered. Due to potential tracheomalacia, the status of “bull frog neck” in achalasia, including severe tracheal compression caused by megaesophagus with concomitant cervical swelling, may also lead to extubation problems and deserves special care in the postoperative period.
Achalasie oder Pseudoachalasie? Fallstricke der Diagnostik und Therapieentscheidung
2007
History Patient 1 (female, aged 55 years) had for some time complained of morning nausea. She reported symptoms of reflux with regurgitation of food for two-and-a-half years and also dysphagia with retrosternal bolus obstruction for the last eighteen months. Patient 2 (male, aged 84 years) complained of restrosternal dysphagia with each intake of food for one year, weight loss of 12 kg and occasional regurgitation of food. Investigations The general condition of patient 1 was only slightly impaired but that of patient 2 markedly reduced. Routine laboratory tests were unremarkable in both. Barium meal in patient 1 revealed fixed narrowing in the region of the esophageal hiatus. The inferior …
