    OBJECTIVE To emphasize the need of an accurate diagnosis of congenital esophageal stenosis due to tracheobronchial remnants, since its treatment differs from other types of congenital narrowing. CASE DESCRIPTION Four cases of lower congenital esophageal stenosis due to tracheobronchial remnants, whose definitive diagnosis was made by histopathology. Except for the last case, in which a concomitant anti-reflux surgery was not performed, all had a favorable outcome after resection and anastomosis of the esophagus. COMMENTS The congenital esophageal stenosis is an intrinsic narrowing of the organâ€(tm)s wall associated with its structural malformation. The condition can be caused by tracheobronchial remnants, fibromuscular stenosis or membranous diaphragm and the first symptom is dysphagia after the introduction of solid food in the diet. The first-choice treatment to tracheobronchial remnants cases is the surgical resection and end-to-end anastomosis of the esophagus. PMID:24142326

    Endoscopic submucosal dissection (ESD) for the treatment of esophageal mucosal lesions is associated with a risk of esophageal stenosis, especially for near-circumferential or circumferential esophageal mucosal defects. Here, we review historic and modern studies on the prevention and treatment of esophageal stenosis after ESD. These methods include prevention via pharmacological treatment, endoscopic autologous cell transplantation, endoscopic esophageal dilatation, and stent placement. This short review will focus on direct prevention and treatment, which may help guide the way forward. PMID:25386186

    Purpose: To determine clinical factors for predicting the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer. Methods and Materials: The study group consisted of 109 patients with esophageal cancer of T1-4 and Stage I-III who were treated with definitive radiotherapy and achieved a complete response of their primary lesion at Kyushu University Hospital between January 1998 and December 2007. Esophageal stenosis was evaluated using esophagographic images within 3 months after completion of radiotherapy. We investigated the correlation between esophageal stenosis after radiotherapy and each of the clinical factors with regard to tumors and therapy. For validation of the correlative factors for esophageal stenosis, an artificial neural network was used to predict the esophageal stenotic ratio. Results: Esophageal stenosis tended to be more severe and more frequent in T3-4 cases than in T1-2 cases. Esophageal stenosis in cases with full circumference involvement tended to be more severe and more frequent than that in cases without full circumference involvement. Increases in wall thickness tended to be associated with increases in esophageal stenosis severity and frequency. In the multivariate analysis, T stage, extent of involved circumference, and wall thickness of the tumor region were significantly correlated to esophageal stenosis (p = 0.031, p < 0.0001, and p = 0.0011, respectively). The esophageal stenotic ratio predicted by the artificial neural network, which learned these three factors, was significantly correlated to the actual observed stenotic ratio, with a correlation coefficient of 0.864 (p < 0.001). Conclusion: Our study suggested that T stage, extent of involved circumference, and esophageal wall thickness of the tumor region were useful to predict the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer.

    In many cases, reflux esophagitis following surgical treatment for esophageal stenosis is caused by the recurrence of that after esophagectomy and esophogogastrostomy. We performed a new management without esophagectomy for a 66-year-old man with sliding hiatal hernia and esophageal stenosis induced by reflux esophagitis. A Expanding Metalic Stent (MES) was inserted to the stenotic portion of the esophagus, and then Collis-Nissen's procedure was done through left thoracotomy and phrenotomy. The postoperative course was satisfactory, and no gastroes-ophageal reflux was detected with the use of 24h pH-monitoring of the esophagus after surgery.

    We report a case of a 56-year-old woman with a history of allogenic bone marrow transplantation for two years, complaining with dysphagia and weight loss. Upper endoscopy revealed esophageal stenosis and extensive mucosa sloughing. Biopsies confirmed the diagnosis of graft-vs-host disease (GVHD). Balloon dilation, corticosteroids and cyclosporin resulted in marked clinical improvement. Gastrointestinal tract is involved in the majority of patients with chronic GVHD. Esophageal manifestations are rare and include vesiculobullous disease, ulceration, esophageal webs, casts or strictures. Sloughing esophagitis along with severe stenosis requiring endoscopic dilation has never been reported in this context. PMID:26290649

    Esophagopericardial fistula is a rare and severe complication, involving several benign, malignant and traumatic pathologies of the esophagus. Only few cases of esophagopericardial fistula have been published so far, as compared to more frequently reported cases of gastropericardial fistula. We report on a 25-year-old female with an esophagopericardial fistula following retrosternal esophagogastroplasty for esophageal caustic stenosis. One month before admission to our hospital, the patient had fever and nonradiating substernal chest pain which was relieved by aspirin, unfortunately without adequate antacid therapy. After 3 weeks, for abdominal pain and worsening chest pain with shock, she was admitted to another hospital and underwent laparotomy: an haemoperitoneum was found, due to a rupture of an ovarian cyst which was removed. For persistent shock, the patient had an echocardiogram which revealed a cardiac tamponade, treated with placement of a pericardic drainage (300 cc of purulent liquid). She was then transferred to our unit: an esophageal swallow with a small amount of methilene blue revealed a fistula between the stomach of the esophagogatroplasty and the pericardium. She eventually underwent surgery. A pericardial window was created, the gastric tube was taken down because of the impossibility to suture the gastric ulcer, and an esophagocoloplasty was used for the reconstruction of the alimentary transit. The postoperative course was unevenqf&l. She is alive and well at 15 months after surgery. Esophagopericardial fistula is a rare complication, with a high mortality rate. A timely decision is mandatory and an aggressive treatment often necessary.

    Aim: To review the patients with esophageal injuries and stenosis with respect to their etiology, clinical course, management, and the lessons learnt from these. Materials and Methods: Retrospective descriptive observation review of children with esophageal injuries and stenosis admitted between January 2009 and April 2015. Results: Eighteen children with esophageal injuries of varied etiology were managed and included, seven with corrosive injury, five with perforation due to various causes, three with mucosal erosion, two with trachea esophageal fistula (TEF), and one wall erosion. The five children who had perforation were due to poststricture dilatation in a child with esophageal atresia and secondary to foreign body impaction or its attempted retrieval in four. Alkaline button cell had caused TEF in two. Three congenital esophageal stenosis (CES) had presented with dysphagia and respiratory tract infection. Six corrosive stricture and two CES responded to dilatation alone and one each of them required surgery. Four of the children with esophageal perforation were detected early and required drainage procedure (1), diversion (1), and medical management (2). Pseudo diverticulum was managed expectantly. Among TEF, one had spontaneous closure and other one was lost to follow-up. All the remaining nineteen children have recovered well except one CES had mortality. Conclusion: Esophageal injuries though rare can be potentially devastating and life-threatening. PMID:27365909

    Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

    Post-esophageal atresia anastomotic strictures and post-corrosive esophagitis are the most frequent types of cicatricial esophageal stricture. Congenital esophageal stenosis has been reported to be a rare but typical disease in children; other pediatric conditions are peptic, eosinophilic esophagitis and dystrophic recessive epidermolysis bullosa strictures. The conservative treatment of esophageal stenosis and strictures (ES) rather than surgery is a well-known strategy for children. Before planning esophageal dilation, the esophageal morphology should be assessed in detail for its length, aspect, number and level, and different conservative strategies should be chosen accordingly. Endoscopic dilators and techniques that involve different adjuvant treatment strategies have been reported and depend on the stricture’s etiology, the availability of different tools and the operator’s experience and preferences. Balloon and semirigid dilators are the most frequently used tools. No high-quality studies have reported on the differences in the efficacies and rates of complications associated with these two types of dilators. There is no consensus in the literature regarding the frequency of dilations or the diameter that should be achieved. The use of adjuvant treatments has been reported in cases of recalcitrant stenosis or strictures with evidence of dysphagic symptoms. Corticosteroids (either systemically or locally injected), the local application of mitomycin C, diathermy and laser ES sectioning have been reported. Some authors have suggested that stenting can reduce both the number of dilations and the treatment length. In many cases, this strategy is effective when either metallic or plastic stents are utilized. Treatment complications, such esophageal perforations, can be conservatively managed, considering surgery only in cases with severe pleural cavity involvement. In cases of stricture relapse, even if such relapses occur following the execution of well

    Development of infantile hypertrophic pyloric stenosis during postoperative period in EA with TEF is rare. Postoperative vomiting or feeding intolerance in EA is more common which is due to esophageal stricture, gastroesophageal reflux and esophageal dysmotility. A typical case of IHPS also presents with non-bilious projectile vomiting at around 3-4 weeks of life. The diagnosis of infantile hypertrophic pyloric stenosis in this subset is usually delayed because of its rarity. We report a case of IHPS in postoperative EA and emphasize on high index of suspicion to avoid any delay in diagnosis with its metabolic consequences.

    In 1972 we described a method for dilatation of esophageal stenosis. The purpose of this paper is to report the results obtained between 1970 and 1989, the patients were studied by X-Rays, "calibration" of the stenosis, endoscopy, biopsy, cytology, gastric analysis and esophageal motility. One hundred and seven patients were treated (mean 60.5 years, M/F 3.9/1). The most frequent etiology was reflux esophagitis (80.3%). Hiatus hernia was present in 84.9%. The stenosis was in the lower third of the esophagus in 92.5%. The BAO was mean: 3.6 mEq/h, and the MAO mean 16.4 mEq/h with a hypersecretion pattern in 33.1% of the cases. Cytology was negative for malignancy in 100%. Biopsy showed esophagitis in 86.9%, Barrett's epithelium in 12.1%, normal tissue in 6.5% and insufficient material in 1.8%. Endoscopy showed 98.1% of grade IV esophagitis. Esophageal motility showed a HPZ of mean 6.5 mmHg. and varying degrees of aperistalsis in 24.3% of the patients. The total number of dilatations was 555 (mean 5.1/pt). The "calibration" of the stenosis previous to the dilatation was mean 8.6 mm, and post dilatation mean 15.6 mm. The result of the procedure was good in 92.5%, regular in 2.8% and bad in 4.6%. The morbidity was 0.9% and the mortality 0.1%. There was relapse of the stenosis in 42% of the cases, the follow-up was mean 3.2 years. Twenty nine patients were submitted to surgery due to failure of the procedure with 68.1% of good results, morbidity of 9% and mortality of 9%. We conclude that this dilatation procedure offers excellent results with a very low morbi-mortality.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. Effect of Slip Time in Forming Neo-Esophageal Stenosis After Replacement of a Thoracic Esophagus With Nitinol Artificial Esophagus.

    Attempts have been made to investigate the effect of slip time of nitinol artificial esophagus for forming neo-esophageal stenosis after replacement of a thoracic esophagus with nitinol artificial esophagus in 20 experimental pigs. The pigs whose slip time was less than 90 days postoperatively had severe dysphagia (Bown's III) immediately after they were fed, and the dysphagia aggravated gradually later on (Bown's III-IV). The pigs whose slip time was more than 90 days postoperatively had mild/moderate dysphagia (Bown's I-II) immediately after they were fed, and the dysphagia relieved gradually later on (Bown's II-I-0). The ratios between the diameter of neo-esophagus in different slip time and normal esophagus were 25% (at 2 months postoperatively), 58% (at 4 months postoperatively), and 93% (at 6 months postoperatively), respectively. The relationship between nitinol artificial esophagus slip time and neo-esophageal stenosis showed a positive correlation. After replacement of a thoracic esophagus with nitinol artificial esophagus, the artificial esophageal slip time not only affected the original diameter of the neo-esophagus immediately, but also affected the neo-esophageal scar stricture forming process later on. The narrowing of neo-esophagus is caused by overgrowth of scar tissue. But there is the positive correlation between artificial esophagus slip time and neo-esophageal stenosis, so this can be a way of overcoming neo-esophageal stenosis by delaying slip time of artificial esophagus.

The patient suffered from serious pharynx anastomotic stenosis after gastric-pha-ryngeal anastomosis. After balloon-dilatation,a domestic self-expanding Z-stents was implanted in the stricture ofthe esophagus under the X-rays. After stent implantation, the patient has been leading a normal life for threeyears. Balloon dilatation and stent implantation is an effective and safe method in the treatment of patients withpharynx anastomotic stenosis.

    Epidermolysis bullosa acquisita (EBA) is a rare auto-immune dermatologic disease, produced by auto-antibodies against colagen VII. We report a 44 years old male patient with EBA diagnosed 15 years before, who presented with progressive disphagia, being diagnosed an esophageal involvement of EBA. The patient was submitted to endoscopic treatment with thermoplastic bougie dilation and intralesional corticosteroid injection. The patient improved clinically with recovery of nutritional status. Esophageal involvement in EBA is very rare and its reason is still unknown. Endoscopic approach must be cautiously performed with the use of small diameter endoscopes, small caliber dilators, intralesional injection of corticosteroid and enteral tube in order to minimize the risks of complications, as well as esophageal rest from food trauma and better reparatory molding of the epithelium.

    In the present study 39 patients with benign esphageal stenosis were studied (average age 59,9 years). The most common etiology was refux esofagitis, and the most common associated pathology was esophageal hiatus hernia. Thirty one patients received medical treatment (diet. antireflux drugs and dilatations.) Twenty four were dilated with the slow continuous method, six with metalic bougies. One patient was not dilated. Seven patients were not treated since the stenosis was due to extrinsec compression. One patient was surgically treated from the onset. Seventy percent of the patients had goods results with esophageal dilatation. We propose that patients with benign esophageal stenosis should be treated by the slow continuous dilatation method.

    Select group of patients with concurrent esophageal and gastric stricturing secondary to corrosive intake requires colonic or free jejunal transfer. These technically demanding reconstructions are associated with significant complications and have up to 18% ischemic conduit necrosis. Following corrosive intake, up to 30% of such patients have stricturing at the pyloro-duodenal canal area only and rest of the stomach is available for rather less complex and better perfused gastrointestinal reconstruction. Here we describe an alternative technique where we utilize stomach following distal gastric resection along with Roux-en-Y reconstruction instead of colonic or jejunal interposition. This neo-conduit is potentially superior in terms of perfusion, lower risk of gastro-esophageal anastomotic leakage and technical ease as opposed to colonic and jejunal counterparts. We have utilized the said technique in three patients with acceptable postoperative outcome. In addition this technique offers a feasible reconstruction plan in patients where colon is not available for reconstruction due to concomitant pathology. Utility of this technique may also merit consideration for gastroesophageal junction tumors. PMID:28070231

    Esophageal tissue engineering is still in an early state, and ideal methods have not been developed. Since the beginning of the 20th century, advances have been made in the materials that can be used to produce an esophageal substitute. Three approaches to scaffold-based tissue engineering have yielded good results. The first development concerned non-absorbable constructs based on silicone and collagen. The need to remove the silicone tube is the main disadvantage of this material. Polymeric absorbable scaffolds have been used since the 1990s. The main polymeric material used is poly (glycolic) acid combined with collagen. The problem of stenosis remains prevalent in most studies using an absorbable construct. Finally, decellularized scaffolds have been used since 2000. The promises of this new approach are unfulfilled. Indeed, stenosis occurs when the esophageal defect is circumferential regardless of the scaffold materials. Cell supplementation can decrease the rate of stenosis, but the type(s) of cells and their roles have not been defined. Finally, esophageal tissue engineering cannot provide a functional esophageal substitute, and further development is necessary prior to conducting human clinical studies.

    Esophageal stent fractures occur quite rarely. A 61-year-old male patient was previously treated for rupture of benign stenosis, occurring after dilatation, by implanting an esophageal stent. However, a year after implantation, the patient suffered from dysphagia caused by the broken esophageal stent. He was treated with the interventional radiology technique, whereby a second implantation of the esophageal stent was carried out quite successfully.

Qualitative information concerning esophageal morphology and function in the various phases of deglutition, and scintigraphic features of achalasia, stenosis, and other pathologies are described. Measured esophageal transit time and its normal variation, its relevance to the diagnosis of esophagitis, and the monitoring of treatment are discussed. This technique observing distinct deglutitions has proven a useful diagnostic tool. Its advantages and limitations are discussed in comparison with other methods.

    The aim of the present study was to investigate esophageal motor function by means of krypton-81m esophageal transit scintigraphy and to compare the results with the functional and morphological data obtained by means of triple lumen manometry and endoscopy. In acute and subacute stages of the disease, all clinical, anatomical, and functional parameters were in good agreement, revealing significant impairment. In chronic stages, the severity of the dysphagia was not correlated to the importance of the residual stenosis. Conversely, 81mKr esophageal transit and manometric's findings were in good agreement with the clinical symptoms, during the entire follow-up period ranging between 3 months to 7 years. The 81mKr test is undoubtedly the easiest and probably the most physiological technique currently available for long-term functional evaluation of caustic esophagitis.

    Iatrogenic esophageal perforation (IEP) is a potentially serious adverse event of interventional endoscopy. The approach to IEP varies from surgical repair for large perforations to conservative treatment for small contained perforations. We report a case of an 18-month-old girl with congenital esophageal stenosis suffering a large esophageal perforation after a trial of stricture dilatation, which was successfully managed by the placement of fully covered stent. Hence, in selected cases, esophageal stent placement is a feasible alternative to invasive surgery in managing IEP. PMID:27144142

    2005-07-01

    Correction of dysphagia in benign esophageal stenosis without the need for surgery is a task that has been tried to be resolved for more than three centuries; in the last three decades this management has evolved with the development of pneumatic dilators and, more recently, alternative and adjuvant treatments like local steroid injection, electrocoagulation, use of argon plasma and the use of expandable stents have been added. The most common causes of benign esophageal stenosis are peptic esophagitis in first place followed by the ingestion of caustic substances; other less frequent etiologies are medication ingestion, stenosis secondary to a surgical anastomosis of the esophagus and stenosis related to mediastinal radiotherapy; the rarest causes include esophageal rings and membranes, sclerotherapy for esophageal varices, the prolonged use of a nasogastric tube, Crohn's disease, among others. A complete clinical, radiological and endoscopic evaluation of the patient is required to make the diagnosis, with the respective complimentary histopathologic study. At present, traditional esophageal dilatations, as well as pneumatic dilatations are the most common and effective treatments, the previously mentioned alternative and adjuvant treatments are used in exceptional cases, some with advantages over the others depending on each patient in particular and on the characteristics and etiology of the stenosis. The future seems to be aimed at the use of temporary expandable stents.

    Four patients with herpetic esophagitis were examined. In three of them, the presenting symptom was odynophagia. Early in the course of herpetic esophagitis, shallow round and oval ulcers were seen on barium esophagograms. Later, the ulcers filled with fibrinous exudate, forming nodular plaques that projected into the esophageal lumen. Although these findings are diagnostic of esophagitis, they are not specific for a herpes virus infection. The definitive diagnosis must be established by histologic examination, which demonstrates the cytopathic effect of the herpes virus infection within the squamous epithelium.

    Despite advances in our knowledge of esophageal cancer, 50% of patients present with incurable disease, and the overall survival after diagnosis is poor. The incidence of esophageal adenocarcinoma of the distal esophagus is rising at a rapid rate in developed countries. Recent advances in the epidemiology of esophageal cancer offer insights into preventive strategies in patients who are at risk. New developments in diagnosis may help detect the disease at an early stage. New diagnostic modalities permit more accurate staging procedures and allow appropriate selection of therapy. New studies provide more information on multimodality therapy for esophageal cancer, and new endoscopic techniques allow resection of small lesions without surgery. New stent designs provide better palliation by providing tumor ingrowth. These developments in the treatment of esophageal cancer are the focus of this review.

    Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition where infiltration of eosinophils into the esophageal mucosa leads to symptoms of esophageal dysfunction. It has rapidly emerged as an important cause of upper GI morbidity in patients of all ages and is encountered in a substantial proportion of patients undergoing diagnostic upper endoscopy. This review discusses the clinical, endoscopic, and histologic features of EoE and presents the most recent guidelines for diagnosis of EoE. It describes selected diagnostic dilemmas including distinguishing EoE from gastroesophageal reflux disease and addressing the newly recognized clinical entity of proton pump inhibitor responsive esophageal eosinophilia. It also highlights evidence to support both pharmacologic and non-pharmacologic treatments, including topical corticosteroids, dietary elimination therapy, and endoscopic dilation. PMID:23452635

    Herein, a case of intramural esophageal dissection is reported and the literature is reviewed. Intramural esophageal dissection is a rare but well described condition that is characterized by a laceration between the esophageal mucosa and submucosa but without perforation. A female patient aged 86 years was hospitalized with a diagnosis of abdominal aortic aneurysm. After placement of an aortic stent, she was started on intravenous heparin. After the procedure, the patient had retching and vomiting due to sedative drugs. On the first day after the procedure, the patient experienced sudden-onset chest pain, hematemesis, back pain and odynophagia. A hematoma was detected in the thoracic esophagus, which was opened during endoscopy and began to bleed suddenly owing to air insufflation. A false lumen was visualized within the esophagus. There was no perforation. The patient was followed up conservatively and discharged from the hospital uneventfully. In conclusion, we propose that esophageal transection, a condition that is widely regarded as relatively benign in the literature, has the potential to lead to perforation. It would be expected that most cases of esophageal transection would be managed conservatively. PMID:28149126

    This review gives an overview of the esophageal anastomosis. The history, various techniques and substitution organs, their advantages and disadvantages, healing mechanism, complications, and actual trend of this essential part of esophageal surgery are described. The history of the esophageal anastomosis extending from the first anastomosis in 1901 to today has undergone more than one century. In the early days, the success rate of the anastomosis was extremely low. As the technology progressed, the anastomosis got significant achievement. Various anastomotic techniques are currently being used. However, controversies exist on the choice of anastomotic method concerning the success rate, postoperative complication and quality of life. How to choose the method, no one can give the best answer. We searched the manuscripts about the esophageal anastomoses in recent years and studied the controversy questions about the anastomosis. Performing an esophageal anastomosis is a technical matter, and suture healing is independent of the patient's biologic situation. Every anastomosis technique has its own merit, but the outcomes were different if it was performed by different surgeons, and we also found that the complication rate of the anastomosis was mainly associated with the surgeons. So the surgeons should learn from their previous experience and others to avoid technical errors.

    Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. In addition, it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modifications, topical corticosteroids and endoscopic dilation can be used alone or in combination. PMID:19115464

    Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus. The improvement of survival observed over the previous two decades is multifactorial and largely attributable to advances in neonatal intensive care, neonatal anesthesia, ventilatory and nutritional support, antibiotics, early surgical intervention, surgical materials and techniques. Indeed, mortality is currently limited to those cases with coexisting severe life-threatening anomalies. The diagnosis of EA is most commonly made during the first 24 h of life but may occur either antenatally or may be delayed. The primary surgical correction for EA and TEF is the best option in the absence of severe malformations. There is no ideal replacement for the esophagus and the optimal surgical treatment for patients with long-gap EA is still controversial. The primary complications during the postoperative period are leak and stenosis of the anastomosis, gastro-esophageal reflux, esophageal dysmotility, fistula recurrence, respiratory disorders and deformities of the thoracic wall. Data regarding long-term outcomes and follow-ups are limited for patients following EA/TEF repair. The determination of the risk factors for the complicated evolution following EA/TEF repair may positively impact long-term prognoses. Much remains to be studied regarding this condition. This manuscript provides a literature review of the current knowledge regarding EA. PMID:22851858

    Background Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice. Aim To demonstrate and to analyze the results of urgent esophagectomy in a series of patients with esophageal perforation. Methods A retrospective study of 31 patients with confirmed esophageal perforation. Most injuries were due to endoscopic dilatation of benign esophageal disorders, which had evolved with stenosis. The diagnosis of perforation was based on clinical parameters, laboratory tests, and endoscopic images. ‪The main surgical technique used was transmediastinal esophagectomy followed by reconstruction of the digestive tract in a second surgical procedure. Patients were evaluated for the development of systemic and local complications, especially for the dehiscence or stricture of the anastomosis of the cervical esophagus with either the stomach or the transposed colon. Results Early postoperative evaluation showed a survival rate of 77.1% in relation to the proposed surgery, and 45% of these patients presented no further complications. The other patients had one or more complications, being pulmonary infection and anastomotic fistula the most frequent. The seven patients (22.9%) who underwent esophageal resection 48 hours after the diagnosis died of sepsis. At medium and long-term assessments, most patients reported a good quality of life and full satisfaction regarding the surgery outcomes. Conclusions Despite the morbidity, emergency esophagectomy has its validity, especially in well indicated cases of esophageal perforation subsequent to endoscopic dilation for benign strictures.

    Lymphocytic esophagitis (LyE) is a rare condition characterised histologically by high numbers of esophageal intraepithelial lymphocytes without significant granulocytes infiltration, in addition to intercellular edema (“spongiosis”). The clinical significance and natural history of LyE is poorly defined although dysphagia is reportedly the most common symptom. Endoscopic features range from normal appearing esophageal mucosa to features similar to those seen in eosinophilic esophagitis, including esophageal rings, linear furrows, whitish exudates, and esophageal strictures/stenosis. Symptomatic gastroesophageal reflux disease is an inconsistent association. LyE has been associated in paediatric Crohn’s disease, and recently in primary esophageal dysmotility disorder in adults. There are no studies assessing effective treatment strategies for LyE; empirical therapies have included use of proton pump inhibitor and corticosteroids. Esophageal dilatation have been used to manage esophageal strictures. LyE has been reported to run a benign course; however there has been a case of esophageal perforation associated with LyE. Here, we describe the clinical, endoscopic and histopathological features of three patients with lymphocytic esophagitis along with a review of the current literature. PMID:28035315

    Of 11,500 children who underwent excretory urography during a 17-year period, three were found to have the rare renal malformation infundibulopelvic stenosis, characterized by caliceal dilatation, infundibular stenosis, and hypoplasia or stenosis of the renal pelvis. The contralateral kidney was absent in two cases and normal in the other. Voiding cystourethrograms were normal in all three. Renal sonography showed a variable degree of caliceal dilatation without associated pelvic dilatation. The diagnosis was confirmed by retrograde ureteropyelography in one case. Two patients were followed for 12 and 18 months, respectively; both remained asymptomatic with normal renal function, and sequential sonographic examinations of their kidneys have shown no significant changes. The third patient died of an unrelated condition. Infundibulopelvic stenosis has highly characteristic radiographic features, and prognosis is good for most affected patients.

    'Benign' aqueduct stenosis is a common cause of hydrocephalus in the paediatric population and is frequently treated by endoscopic third ventriculostomy. Occasionally, aqueduct stenosis can be a prelude to the development of other pathology, as is seen in these two cases of pineal tumours developing in patients whose hydrocephalus was successfully treated with endoscopic third ventriculostomy. The case histories are presented, along with the recommendation for increased radiological screening of patients with this usually 'benign' presentation.

  15. Esophageal dilation in eosinophilic esophagitis.

    2015-10-01

    Tissue remodeling with scaring is common in adult EoE patients with long standing disease. This is the major factor contributing to their complaints of solid food dysphagia and recurrent food impactions. The best tests to define the degree of remodeling are barium esophagram, high resolution manometry and endoscopy. Many physicians are fearful to dilate EoE patients because of concerns about mucosal tears and perforations. However, multiple recent case series attest to the safety of esophageal dilation and its efficacy with many patients having symptom relief for an average of two years. This chapter will review the sordid history of esophageal dilation in EoE patients and outline how to perform this procedure safely. The key is graduated dilation over one to several sessions to a diameter of 15-18 mm. Postprocedural pain is to be expected and mucosal tears are a sign of successful dilation, not complications. In some healthy adults, occasional dilation may be preferred to regular use of medications or restricted diets. This approach is now supported by recent EoE consensus statements and societal guidelines.

    Esophageal moniliasis is found rarely. It has been described mainly in chronically ill patients, who receive antibiotics and corticoesteroids. Early diagnosis and treatment betters their prognosis. Nine patients, 5 males and 4 females were studies in Hospital General del Centro Medico Nacional in Mexico City. Their agesranged from 26 to 77 years, with a mean of 49 years. All patients were chronically ill and 7 of them were treated in the intensive care unit. Three had disphagia, 3 retrosternal pain, and 2 gastrointestinal hemorrhage. Eight patients had high W.B.C., 3 irregular filling defects on X ray studies, and on endoscopy, all showed a pseudomembranous white yellowish exudate, underneath it the mucosa was inflamed, irregular and bled scantily. In 5 out of 9 patients biopsy and a smear confirmed the diagnosis. Eight patients treated with nystatin were cured. This disorder must be suspected in patients with disphagia and retrosternal pain; esophagoscopy is the prefered procedure to establish this diagnosis.

    Lumbar spinal stenosis, the results of congenital and degenerative constriction of the neural canal and foramina leading to lumbosacral nerve root or cauda equina compression, is a common cause of disability in middle-aged and elderly patients. Advanced neuroradiologic imaging techniques have improved our ability to localize the site of nerve root entrapment in patients presenting with neurogenic claudication or painful radiculopathy. Although conservative medical management may be successful initially, surgical decompression by wide laminectomy or an intralaminar approach should be done in patients with serious or progressive pain or neurologic dysfunction. Because the early diagnosis and treatment of lumbar spinal stenosis may prevent intractable pain and the permanent neurologic sequelae of chronic nerve root entrapment, all physicians should be aware of the different neurologic presentations and the treatment options for patients with spinal stenosis.

    2012-01-01

    Eosinophilic Esophagitis (EoE) is a chronic inflammatory disease of the esophagus triggered by an immune response that leads to symptoms of dysphagia, chest pain, and food impaction. EoE is a clinicopathologic syndrome that requires clinical symptoms and pathologic findings for a diagnosis. The inflammatory process and eosinophilic infiltration of the esophagus in EoE lead to fibrosis and structural changes within the esophagus that cause esophageal dysfunction. The biomechanics of the esophageal function in EoE have been explored using manometry, impedance planimetry, barium esophagograms, and endoscopic ultrasound. These studies have identified several biomechanical changes to the esophagus in EoE including pan-esophageal pressurization on manometry, changes in esophageal compliance with decreased distentisbility by impedance planimetry, decreased esophageal luminal diameter by esophagograms, and dysfunction in the esophageal longitudinal muscles by endoscopic ultrasound. Treatments for the disease involve dietary changes, immunosuppressive drugs, and dilation techniques. However, the data regarding the effect of these therapies on altering mechanical properties of the esophagus is limited. As the pathogenesis of esophageal dysfunction in EoE appears multifactorial, further study of the biomechanics of EoE is critical to better diagnose, monitor and treat the disease. PMID:23105995

    Recent advances in and controversies concerning the management of children with congenital valvular aortic stenosis are discussed. In neonates with critical aortic stenosis, improved survival has recently been reported after surgical open valvotomy and balloon valvuloplasty, although it is difficult at this point to compare the results of the two procedures and determine their differential indications. Good results have also been achieved after extended aortic valvuloplasty for recurrent aortic stenosis and/or insufficiency, but the length of follow-up in these patients is still short. The technique first reported in 1991 for bilateral enlargement fo a small annulus permits the insertion of an aortic valve 3-4 sizes larger than the native annulus. It entails no risk of distorting the mitral valve, damaging the conduction system or important branches of the coronary arteries, or resulting in left ventricular dysfunction. The Ross procedure is now widely applied in the West, with reports of early mortality rates of less than 5% and event-free survival rates of 80-90% during follow-up of 4-8 years. Longer follow-up and continued careful evaluation are required to resolve the issue of possible dilatation and subsequent neoaortic valve dysfunction and pulmonary stenosis due to allograft degeneration after pulmonary autograft root replacement in children.

    2010-01-01

    Eosinophilic esophagitis (EoE) is a chronic clinicopathological entity characterized by large numbers of intraepithelial eosinophils infiltrating the esophageal mucosa. The inflammation leads to alterations in the caliber and the motility of the organ, which determines esophageal symptoms, especially dysphagia and frequent food impaction. Firstly described in 1978, EoE represents today an increasingly recognized disease, with cases coming from all developed countries and rising epidemiology. The origin of EoE has been related to allergy to food components or inhalants, and a number of studies support a Th2-type reaction in the origin of the disease. Thus, several treatment strategies based on controlling the exposition to triggering allergens or therapies using anti-allergic drugs have demonstrated efficacy in EoE. Since EoE frequently presents with esophageal stenosis, endoscopic dilation has been also used in treating these patients, but a high risk of complications has been documented. However, single treatment strategies have not been compared to a placebo group in most of studies, and we do not know the long-term consequences of eosinophilic inflammation, esophageal fibrous remodeling or its possible modifications using different therapies. Furthermore, we lack of a common accepted therapeutic end-point to assess the efficacy of the treatment: from mere resolution of symptoms to full control of esophageal inflammation. This article summarizes the current knowledge about the epidemiology, origin and pathogenesis of the disease, and discuses several practical questions, especially those related to how the affected patients should be treated.

    Dysphagia after antireflux surgery is often a challenging situation. We report the case of a patient with relapsing cardial stricture and a weight loss of 24 kg following a laparoscopic Nissen procedure. Initial presentation was consistent with the diagnosis of pseudoachalasia and was resistant to endoscopic dilatation. Dysphagia was relieved by surgery, which showed cardial strangulation by tightly sutured diaphragmatic pillars. Symptoms and cardial stricture relapsed after a few months with no significant relief after repeated dilatations. Conservative treatment by endoscopic transcardial prosthesis for six weeks allowed a return to normal diet and a weight gain of 10 kg within a 30-month followup period.

    Purpose: To evaluate the clinical use of covered and noncovered, knitted nitinol stents in patients presenting new stent indications. Methods: Self-expandable, knitted nitinol stents were implanted in four patients for treatment of dysphagia. In two patients who had malignant strictures and had esophago-respiratory fistulae and in one patient with an esophagocutaneous fistula, polytetrafluoroethylene (PTFE)-covered stents were implanted. One patient received a noncovered stent, but a retrograde approach through a percutaneous endoscopic gastrostomy (PEG) fistula had to be chosen for recanalization of an esophageal occlusion. Two patients received stents for treatment of benign strictures. Results: Recanalization of the stricture and stent implantation were performed under fluoroscopic control without any procedure-related morbidity or mortality. Dysphagia improved in all patients and the esophageal fistulae could be sealed off by covered stents. During a maximum follow-up of 18 months, there was no stent migration or esophageal perforation. Complications observed were stent stenosis due to food impaction (1/4) and benign stent stenosis (2/2). Most complications could be treated by the interventional radiologist. Conclusion: Self-expandable, covered Nitinol stents provide an option for the treatment of dysphagia combined with esophageal fistulae. In combination with interventional radiology techniques, even complex strictures are accessible. For benign strictures, the value of stent treatment has not yet been proven.

  7. From Reflux Esophagitis to Esophageal Adenocarcinoma.

    PubMed

    Souza, Rhonda F

    Reflux esophagitis causes Barrett's metaplasia, an abnormal esophageal mucosa predisposed to adenocarcinoma. Medical therapy for reflux esophagitis focuses on decreasing gastric acid production with proton pump inhibitors. We have reported that reflux esophagitis in a rat model develops from a cytokine-mediated inflammatory injury, not from a caustic chemical (acid) injury. In this model, refluxed acid and bile stimulate the release of inflammatory cytokines from esophageal squamous cells, recruiting lymphocytes first to the submucosa and later to the luminal surface. Emerging studies on acute reflux esophagitis in humans support this new concept, suggesting that reflux-induced cytokine release may be a future target for medical therapies. Sometimes, reflux esophagitis heals with Barrett's metaplasia, a process facilitated by reflux-related nitric oxide (NO) production and Sonic Hedgehog (Hh) secretion by squamous cells. We have shown that NO reduces expression of genes that promote a squamous cell phenotype, while Hh signaling induces genes that mediate the development of the columnar cell phenotypes of Barrett's metaplasia. Agents targeting esophageal NO production or Hh signaling conceivably could prevent the development of Barrett's esophagus. Persistent reflux promotes cancer in Barrett's metaplasia. We have reported that acid and bile salts induce DNA damage in Barrett's cells. Bile salts also cause NF-x03BA;B activation in Barrett's cells, enabling them to resist apoptosis in the setting of DNA damage and likely contributing to carcinogenesis. Oral treatment with ursodeoxycholic acid prevents the esophageal DNA damage and NF-x03BA;B activation induced by toxic bile acids. Altering bile acid composition might be another approach to cancer prevention.

    The association of congenital tracheal stenosis and tracheoesophageal (TE) fistula is rare. Here, we report 2 patients with tracheobronchial stenosis (complete cartilage ring) involving the lower trachea and right bronchus. Both patients had associated VACTERL (vertebral anomalies, anal atresia, cardiovascular anomalies, TE, renal, and limb defects) congenital cardiac defects and tracheal diverticula after repair of the TE fistula in type C esophageal atresia. The stenotic segment began at the orifice of the TE fistula, which became diverticula after the TE fistula was repaired. Concomitant repair of congenital cardiac defects and a slide tracheoplasty with elimination of the diverticula were performed successfully.

    2015-01-01

    Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments.

    Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments. This review summarizes the evidence on EoE pathophysiology and illustrates the safety and efficacy of the most recent medical and endoscopic treatments.

    Benign subglottic stenosis represents a major therapeutic challenge. Interventional bronchoscopic treatment has a limited role in this setting due to anatomical and technical reasons. The benefit with these techniques is generally temporary, due to frequent recurrences, need for repeated procedures and risk of extending the area of damage. Laryngotracheal resection is at present the curative treatment of choice. Literature data show that surgical treatment may allow very high success rates at long term with low perioperative morbidity and mortality. Technical aspects and results are reported and discussed.

    The authors studied 37 patients belonging to the Pediatric Cardiology Service of the Institute National of Cardiology who were carriers of fixed fibrinous subaortic stenosis. The diagnosis was established by surgery or autopsy. Isolated subvalvular obstruction was found in 24 patients (63%), which represents the most important number of cases in the literature. The analysis of the 24 cases permitted important conclusions: 1. All the patients had systolic thrills in the suprasternal hollow and carotidinous pathways. 2. No case had protosystolic click. In all, the murmur's epicenter was in the 3rd and 4th IIS in the parasternal line, a fact which can lead to a mistaken diagnosis of interventricular septal defect. 66.6% of the patients had a diastolic murmur heard in the aortic focus, a secondary accompaniement to secondary valvular aortic insufficiency. The intensity of the second aortic sound held an inverse relationship to the magnitude of the gradient. The presence of paradoxic splitting of the second heart sound as well as prolongation of the expulsion period in the carotidogram are indexes for the severity of the obstruction. 3. A relationship between the severity of the lesion and the dilatation of the left atrium was found. The cardiomegaly had no relationship to the severity of the obstruction with the increase in ventricular telediastolic pressure or to the evolution time. 4. An adequate hemodynamic study permits evaluating and locating the site of the obstruction. Likewise, precise ventriculography appraises the nature of the narrowing. 5. Aortic regurgitation is located at the valvular level. Aortography permits its affirmation. Probably the stream coming from subvalvular stenosis produces fibrosis or asynchronism in the closing of the aortic valves. 6. Surgical treatment offers excelent perspectives in mortality as well as reducing the gradient. None of our patients operated on had hospital or later death. 7. Postoperatory evaluation was performed on six

    Dilatations are considered the election treatment for esophageal stenosis of different etiologies. Different methods of dilatation have been used through the years. Security and effectiveness are the main subjects when we choose a dilatation method. We present the results of the last 3 years that Savary-Guilliard have been used, with a guide wire probe, under endoscopic control. Six patients with postsurgical stenosis and 10 with post lye ingestion stenosis were treated with the above mentioned method. The site of stenosis is localized under flexible endoscopy, and a special guide wire probe is introduced to the stomach. Once the wire is in place, different diameter bougies are introduced until a firm resistance is felt or the desired diameter is reach. In complicated cases the progression of the wire was controlled by X-rays. A total of 208 dilatations have done in 16 patients over the last three years. Six patients with postsurgical stenosis needed from two to six dilatations for their cure. Of the 10 patients who ingest lye, none of them had needed a gastrostomy. Three of them have no dysphagia after 9, 13 and 13 dilatations. The other 7 are under dilatations every 6 weeks in 6 cases and every 4 weeks in one case, been all of them in the second year of treatment. All the dilatations have been performed under general anesthesia, as outpatients. We have not had any complication under this treatment. We have found that the Savary-Guilliard method is adequate for esophageal dilatations in pediatric population. Security and effectiveness are the main points of this procedure, there is no need for a gastrostomy, and the child will have a better quality of life. This procedure is less aggressive, and this will give a shorter postop period, with no complications and the child will have a longer period of normal life between dilatations.

    A 72 year-old female developed a herpetic esophagitis after 3 d of oral corticotherapy for an acute exacerbation of chronic obstructive pulmonary disease, presenting as odynophagia and total dysphagia. Biospies were taken during a first esophagogastroduodenoscopy (EGD) and the patient was referred to the thoracic surgery service with a presumptive diagnosis of esophageal cancer. A second EGD was planned for dilatation, but by that time the stenosis was completely resolved. The biopsies taken during the first EGD revealed multiple herpetic viral inclusions and ulcerations without any dysplasia or neoplasia. In front of a severe esophageal stenosis, one must still exclude the usual differential diagnosis peptic stenosis and cancer. Visualization of endoscopic lesions can suggest the diagnosis but must be promptly confirmed by biopsy, viral culture or polymerase chain reaction. Although immune systemic effects of corticotherapy are well known and herpetic esophagitis occurs most frequently in immunocompromised individuals, this case emphasizes the importance of clinical awareness concerning short courses of corticotherapy for immunocompetent individuals. This article discusses the reactivation process of herpetic infection in this context and addresses its diagnostic and therapeutic issues. PMID:23964155

    Twenty-eight patients presenting with low back pain, associated with sciatic or femoral neuropathy, were found to have lateral recess stenosis occurring as a result of hypertrophy of the facet joints, with preservation within normal limits of the sagittal AP diameter of the lumbar canal. Pathology was believed to be traumatic in origin, and the variable nature of the adhesions suggested recurrent inflammation; the hypertrophy of the facet joints may have been the result of traumatic inflammatory hyperaemia. Radiological investigations were unhelpful. The diagnosis of the condition was made at the time of surgical exploration by the findings of alteration of the facet joints, adhesions and fixity of the nerve roots, normal sagittal AP diameter of the canal, and absence of other significant lesions. Gratifying results were obtained with decompression by wide laminectomy with excision of overhanging facet joints and release of adhesions. PMID:894321

    2016-02-15

    Functional esophageal disorders consist of a disease category that present with esophageal symptoms (heartburn, chest pain, dysphagia, globus) not explained by mechanical obstruction (stricture, tumor, eosinophilic esophagitis), major motor disorders (achalasia, EGJ outflow obstruction, absent contractility, distal esophageal spasm, jackhammer esophagus), or gastroesophageal reflux disease (GERD). While mechanisms responsible are unclear, it is theorized that visceral hypersensitivity and hypervigilance play an important role in symptom generation, in the context of normal or borderline function. Treatments directed at improving borderline motor dysfunction or reducing reflux burden to sub-normal levels have limited success in symptom improvement. In contrast, strategies focused on modulating peripheral triggering and central perception are mechanistically viable and clinically meaningful. However, outcome data from these treatment options are limited. Future research needs to focus on understanding mechanisms underlying visceral hypersensitivity and hypervigilance so that appropriate targets and therapies can be developed.

    In this report, we describe the esophageal atresia in terms of current surgical management on the basis of our experience and literatures. Traditionally, infants with esophageal atresia have presented shortly after birth because of an inability to pass an orogastric tube, respiratory distress, or an inability to tolerate feeding. And also, an isolated trachea-esophageal fistula (TEF) usually cases coughing, recurrent pneumonia, or choking during feedings. To ignore these symptoms is to risk a delayed diagnosis. The condition may be associated with other major congenital anomalies such as those seen in the vertebral, anal, cardiac, tracheo-esophageal, renal/radial (VACTER) association, or it may be an isolated defect. Therapeutic strategies for esophageal atresia are a prevention of pulmonary complication by TEF closing and an early establishment of enteral alimentation. We promptly repair healthy infants without performing a gastrostomy and delay repair in infants with high-risk factors such as associated severe cardiac anomaly and respiratory insufficiency. Esophageal atresia has been classically approached through a thoracotomy. The disadvantages of such a thoracotomy have been recognized for a long time, for example winged scapula, elevation of fixation of shoulder, asymmetry of the chest wall, rib fusion, scoliosis, and breast and pectoral muscle maldevelopment. To avoid such disadvantages, thoracoscopic repair was recently reported.

    Radiotherapy and surgery have both played prominent roles in the treatment of esophageal cancer since the beginning of the 20th century. Although the use of radiotherapy alone to treat esophageal cancer has a long history, it has not demonstrated improved outcomes compared with surgery alone. The disappointing rates of survival and local control associated with single-modality therapy and the need for effective nonsurgical management led to the development of definitive chemoradiotherapy paradigms for esophageal cancer. Adding cytotoxic chemotherapy to radiotherapy for additive or synergistic effect was described as early as 1968, and over time, treatment has shifted from single-modality therapy toward combined-modality therapy using chemotherapy and radiotherapy. This approach eventually demonstrated superior outcomes in patients with esophageal cancer when compared to radiotherapy alone. Maximum benefit of this therapy depends on the appropriate addition of surgery and the optimization of radiosensitizing chemotherapy. A burgeoning area of research has focused on improving definitive chemoradiotherapy strategies through the incorporation of newer chemotherapeutic agents and targeted biologic agents. An overview of the history of chemoradiotherapy in the treatment of esophageal cancer is presented, as well as a discussion of ongoing studies and future areas of promising research. PMID:19461907

    Introduction Intramural esophageal tumors (IET) are located between unchanged mucous membrane and muscularis mucosae. They can be both benign and malignant. Aim To evaluate diagnostic and therapeutic difficulties of IET. Material and methods During the years 2010–2015, 11 patients with IET were treated in our clinic. Diagnostics included gastroscopy, computed tomography of the chest, endoscopic ultrasound (EUS) guided fine needle biopsy, and positron emission tomography (PET) of the esophagus in cases with no histopathological confirmation. Results Based on the conducted analysis we diagnosed 1 case of gastrointestinal stromal tumor (GIST), 1 case of adenocarcinoma, and 2 cases of esophageal cysts. In another 7 cases radiological images resembled leiomyoma but with no histopathological confirmation. Esophagectomy was performed in 2 cases of malignant tumors and 1 case of a large benign tumor. In other cases surgical enucleation of tumors was performed. Postoperatively we diagnosed 6 cases of leiomyoma, 1 case of schwannoma, 2 esophageal cysts, 1 case of GIST and 1 of esophageal cancer. Conclusions Intramural esophageal tumors is a very diverse group of tumors, both malignant and benign. In every case of IET we should seek histopathological conformation. Treatment of IET depends on localization, size and histopathological type of lesion. PMID:28096828

    Esophageal achalasia is due to the esophagus of neuromuscular dysfunction caused by esophageal functional disease. Its main feature is the lack of esophageal peristalsis, the lower esophageal sphincter pressure and to reduce the swallow's relaxation response. Lower esophageal muscular dissection is one of the main ways to treat esophageal achalasia. At present, the period of muscular layer under the thoracoscope esophagus dissection is one of the treatment of esophageal achalasia. Combined with our experience in minimally invasive esophageal surgery, to improved incision and operation procedure, and adopts the model of the complete period of muscular layer under the thoracoscope esophagus dissection in the treatment of esophageal achalasia.

    Dysphagia, or difficulty swallowing, is a common problem. Although most cases are attributable to benign disease processes, dysphagia is also a key symptom in several malignancies, making it an important symptom to evaluate. The differential diagnosis of dysphagia requires an understanding of deglutition, in particular the oropharyngeal versus esophageal stages. Stroke is the leading cause of oropharyngeal dysphagia, which is common in older adults and frequently presents as part of a broader complex of clinical manifestations. In esophageal dysphagia, difficulty swallowing is often the main complaint and is caused by localized neuromuscular disorders or obstructive lesions.

    Eosinophilic esophagitis (EoE) is an inflammatory immune-mediated disease with predominant eosinophilic inflammation characterized by the presence of esophageal dysfunction symptoms. Treatment delay can be associated with disease complications, like esophageal strictures, that can justify the use of invasive procedures which are not deprived of side effects. We present a case report of a 14 year old child with severe esophageal stricture secondary to EoE, that was treated with topical and systemic corticosteroid before any invasive procedure was considered. After 26 weeks of medical treatment, significant improvement of esophageal dysfunction occurred with histological remission and stricture resolution. In patients with severe esophageal strictures secondary to EoE, the need for esophageal dilation procedures should be considered only after anti-inflammatory treatment.

    Esophageal strictures due to malignant diseases are treated with self-expanding metalicic stents. However, experience is limited with these metalic stents in the cervical esophagus. Due to technical difficulties and procedure-related complications, the cervical esophagus has been assigned as a risky area for stenting procedures. Another encountered problem is patient discomfort after the procedure. In this case report, we present three patients with cervical esophageal strictures who were successfully treated with self-expandable metalic stents. Two of these patients had inoperable esophageal carcinoma and the third had benign stenosis due to radiotherapy of larynx carcinoma. The two patients with malignant disease survived four and six months, respectively, after the procedure. The last patient with benign disease is still alive and has been without dysphagia symptom for six months.

    A 74-year-old woman with extensive lichen planus mucosae (LPM) developed stenotic esophagitis that was refractory to intravenous glucocorticosteroids. Esophageal dilatations to 14 mm width were repeatedly performed without any lasting effect. After introducing oral apremilast, she experienced complete clinical remission within the first 4 weeks of treatment. Control esophagoscopy confirmed a marked recovery of the esophageal mucosa with no recurrence of the former stenosis. Our observation is in line with the case series of Paul et al. [J Am Acad Dermatol 2013;68: 255–261] who first reported on the benefit of apremilast in patients with extensive LPM. Ideally, the effectiveness of apremilast in LPM should be studied in a randomized controlled trial. PMID:27721755

    Objectives To conduct a systematic review and meta-analysis of studies comparing the gastric-tube vs. whole-stomach for esophageal cancer in order to determine the optimal surgical technique of esophagectomy. Methods A comprehensive literature search was performed using PubMed, EMBASE, ScienceDirect, Ovid MEDLINE, Cochrane Library, Web of Science, Google Scholar, and Scopus. Clinical trials that compared the gastric-tube versus whole-stomach for esophageal cancer were selected. The clinical endpoints included anastomotic leakage, anastomotic stenosis, reflux esophagitis, pneumonia, delayed gastric emptying, and thoracic stomach syndrome. Results A total of 6 articles (1571 patients) were included. Compared to the whole-stomach approach, the gastric-tube approach was associated with a lower incidence of reflux esophagitis (95% confidence interval [CI]: 0.16 to 0.81, p = 0.01) and thoracic stomach syndrome (95% CI: 0.17 to 0.55, p < 0.0001). The rates of anastomotic leakage, anastomotic stenosis, pneumonia, and delayed gastric emptying did not significantly differ between the two groups. Conclusions The gastric-tube esophagectomy is superior to the whole-stomach approach, as it is associated with a lower incidence of postoperative reflux esophagitis and thoracic stomach syndrome. Our findings must be validated in large-scale randomized controlled trials. PMID:28267808

    2014-01-01

    Eosinophilic esophagitis (EoE) is a chronic inflammatory process characterized by symptoms of esophageal dysfunction and, histologically, by eosinophilic infiltration of the esophagus. In adults, it commonly presents with dysphagia, food impaction, and chest or abdominal pain. Chronic inflammation can lead to diffuse narrowing of the esophageal lumen which may cause food impaction. Endoscopic procedures to relieve food impaction may lead to complications such as esophageal perforation due to the friability of the esophageal mucosa. Spontaneous transmural esophageal rupture, also known as Boerhaave's syndrome, as a primary manifestation of EoE is rare. In this paper, we present two adult patients who presented with esophageal perforation as the initial manifestation of EoE. This rare complication of EoE has been documented in 13 other reports (11 adults, 2 children) and only 1 of the patients had been previously diagnosed with EoE. A history of dysphagia was present in 1 of our patients and in the majority of previously documented patients. Esophageal perforation is a potentially severe complication of EoE. Patients with a history of dysphagia and patients with spontaneous esophageal perforation should warrant an evaluation for EoE. PMID:24899902

    Introduction Esophageal diverticulum, a relatively rare condition, has been considered to be associated with motor abnormalities such as conditions that cause a lack of coordination between the distal esophagus and lower esophageal sphincter. Presentation of case We herein report a case of esophageal epiphrenic diverticulum associated with diffuse esophageal spasm. A 73-year-old woman presented with dysphagia and regurgitation. Imaging examinations revealed a right-sided esophageal diverticulum located about 10 cm above the esophagogastric junction. High-resolution manometry revealed normal esophageal motility. However, 24-h pH monitoring revealed continuous acidity due to pooling of residue in the diverticulum. An esophageal epiphrenic diverticulum was diagnosed and resected thoracoscopically. Her dysphagia recurred 2 years later. High-resolution manometry revealed diffuse esophageal spasm. Discussion The diverticulum in the present case was considered to have been associated with diffuse esophageal spasm. The motility disorder was likely not identified at the first evaluation. Conclusion In this case, the patient’s symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. PMID:26143577

    1983-12-01

    Gastroesophageal reflux has been incriminated as a factor-inhibiting acquisition of esophageal speech after laryngectomy. Fourteen proficient esophageal speakers and 10 nonproficient speakers underwent esophageal manometry, esophageal pH probe testing, and Bernstein acid perfusion testing. Additionally, 175 laryngectomized members of Lost Chord Clubs answered mailed questionnaires about the frequency of reflux symptoms. Nonproficient and proficient esophageal speakers had a similar frequency of gastroesophageal reflux by pH probe testing, esophageal mucosal acid sensitivity by Bernstein testing, lower esophageal sphincter pressures, and gastroesophageal reflux symptoms. Gastroesophageal reflux does not appear to be a major factor in preventing esophageal speech.

    Symptoms of chest pain and dysphagia are common in the adult population. Most patients initially undergo an evaluation to exclude anatomic causes (ie, esophagitis, stricture) and cardiovascular disease as the etiology of these symptoms. Patients with persistent symptoms may then be referred for specialized testing of the esophagus, including esophageal manometry. Disorders of esophageal motility, which include achalasia, diffuse esophageal spasm, nutcracker esophagus, hypertensive lower esophageal sphincter, and ineffective motility are often identified in these patients. Unfortunately, the etiology of these disorders has not been well characterized and the treatment has not been standardized. This review will briefly discuss the impact, etiology, and diagnosis of esophageal motility disorders, and then focus on the medical management of these disorders using evidence from well-designed, prospective studies, where available.

    A 50-year-old woman was referred to our hospital for dysphagia and several episodes of esophageal food impaction during the prior three months. Complete blood count and basic biochemical tests were normal. No eosinophilia was found. Esophagogastroduodenoscopy (EGD) revealed the presence of concentric rings (esophageal "trachealization") and stenosis along the middle and distal esophagus. Endoscopic ultrasound (EUS) showed circumferential thickening of all layers in the same part. Cytopathologic evaluation of a specimen obtained by endoscopic biopsy of the thickened area in the distal esophagus showed eosinophilic infiltration (20 eosinophils per high-powered field). She was diagnosed as having eosinophilic esophagitis (EoE). Topical steroid therapy was started. A tendency of dysphagia for relief and improvement of characteristic EGD findings began early, but wall thickening in EUS remained. Past reports of the related literature have described that thickness of submucosa and muscularis propria remained after therapy, although significant reduction in the mucosal thickness was provided by short-term steroid therapy. One explanation for early relapse is insufficient reduction in the submucosa and muscularis propria. Consequently, our patient was given steroids until thickness on EUS improved. EUS is regarded as useful for evaluating the curative effect in patients with EoE.

    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. A female patient, 39 years old, with a history of previous suicide attempts, was admitted to the Emergency Room with chest pain and dysphagia after voluntary ingestion of 2 cell batteries. Two cell batteries are easily detected in a routine chest X-ray, presenting a characteristic double-ring shadow, or peripheral halo. Urgent oral endoscopy was performed 10 hours after ingestion, showing a greenish-gray lumpy magma-like consistency due to leakage of battery contents. The 2 batteries were sequentially removed with alligator-jaw forceps. After flushing and aspiration of the chemical material, a broad and circumferential injury with denudation of the mucosa and two deep ulcerations with necrosis were observed where the batteries had been. The batteries' seals were eroded, releasing chemical contents. Despite the severity of the injuries, the patient progressed favorably and there was no esophageal perforation. Esophageal impaction of cell batteries should always be considered an endoscopic urgency.

    Eosinophilic esophagitis (EoE) has only rarely been reported in esophageal atresia (EA) patients. A retrospective case analysis of all EA patients born at our center between January 1999 and April 2012 was performed. A total of 113 of patients were identified; 10 patients were excluded as a result of inadequate data. Eighteen patients (17%) were diagnosed with EoE. The average number of eosinophilis was 30/high-power field (HPF) (19/HPF-80/HPF). The median age for diagnosis of EoE was 1 year and 6 months (8 months-8 years and 7 months). Children with EoE had a significantly greater incidence of reflux symptoms, dysphagia, tracheomalacia, and 'hypoxic spells' (P < 0.05). EoE patients also underwent significantly more surgery including fundoplication and aortopexy when compared with those without EoE (P < 0.0001). Although the incidence of gastrostomy was greater in the EoE group (33% vs. 13%), this was not statistically significant. Half of the EoE patients had a coexisting atopic condition at time of diagnosis. The commonest condition was asthma 7/18 (38%) followed by specific food allergy 6/18 (33%). EoE was treated in 11 patients with either swallowed fluticasone or budesonide slurry. All improved clinically. Histologically, five had complete resolution and six had partial improvement. Six children with EoE were treated with acid suppression alone. All improved clinically, and 5/6 had subsequent histological resolution. One child who received acid suppression and an exclusion diet also improved. Seven patients (38%) had an esophageal stricture at time of EoE diagnosis. Five were dilated at time of the initial endoscopy, prior to the diagnosis of EoE being available. Two patients had resolution of their strictures on medical treatment of their EoE alone and did not require further dilatation. EoE was seen in 17% of children with EA in this study. EoE should be considered in EA patients with persistent symptoms on standard reflux treatment, increasing

    Eosinophilic esophagitis (EoE) is a relatively new entity with a significant amount of increased recognition over the last decade. The mainstay treatments of EoE are designed to eliminate the causative allergens or to reduce their effects on the esophageal mucosa. Common treatments include dietary modification, proton pump inhibitors, systemic and topical corticosteroids, and endoscopic treatments. As the pathogenesis of EoE is explored, new and novel treatments are being studied that target specific pathways and chemokines identified in as precipitating agents of EoE. This is a rapidly evolving field with significant ongoing research and clinical studies. Our review will therefore focus on current and novel treatment approaches to the disease.

    Eosinophilic esophagitis (EoE) is a newly recognized disease and is an emerging entity throughout developing and developed countries, including the United States. Therefore, understanding the causes, natural history, diagnosis, and management is important for future therapeutic interventions. The pathogenesis of EoE is still not clear, but a growing body of evidence has established that this condition represents a T-cell-mediated immune response involving several proinflammatory mediators and chemoattractants known to regulate eosinophilic accumulation in the esophagus, such as IL-4, IL-5, IL-3 and eotaxin-1, -2, and -3. Determining the mechanism or mechanisms through which human esophageal-derived factors ultimately induce the functional abnormalities observed, and to which antigens patients who have EoE are sensitized that lead to the manifestation of symptoms, is of significant interest.

    During the period included between January 1970 and December 1990, we studied 242 patients with manometric and radiological diagnosis of esophageal achalasia. Eight of these patients (3.3%) developed during the evolution of their disease an esophageal carcinoma. Eight cases showed histologic type of epidermoid carcinoma: 3 differentiated, 3 semi-differentiated and 2 anaplastic. Therapy for achalasia was: one patient, Heller myotomy, 4 patients, dilatations with bougies in numerous opportunities, and the other two patients receive no treatment for achalasia. Two patients reported tracheobronchial fistulas as complication of carcinoma. Treatment received for carcinoma included: three patients, radiotherapy (4000 rads); one patient, chemotherapy; one patient, chemotherapy and radiotherapy, one resection surgery and two patients feeding gastrostomy. All of the eight patients died within the year of diagnosis of epidermoid carcinoma.

    Fibrovascular polyps are extremely rare benign neoplasias of the esophagus, which usually originate in the lower cricoid area. They do not produce any discomfort in the patient for a long time, however it may make itself evident by the patient's regurgitation of the polyp, producing asphyxia or, more frequently, dysphagia. The case of a 58 year old male patient is presented herein, with a 9 month record of dysphagia, weight loss and intermittent melena. The barium x-ray showed a distended esophagus, with a tumor running from the upper esophageal sphincter to the cardia. The endoscopy confirmed the presence of a pediculated tumor, implanted in the cervical esophagus. Surgeons suspected the potential malignancy of the tumor and performed a transhiatal esophagectomy. The final pathologic diagnosis was giant fibrovascular esophageal polyp.

    Cardiac CT scan has emerged from a research tool to a widely used clinical modality in the diagnostic management of coronary artery disease. Based on evidence of numerous clinical studies coronary CT angiography (cCTA) has emerged as a fast, accurate, and noninvasive alternative to conventional angiography in selected patient populations. A major strength of cCTA is its ability to combine information on the coronary artery anatomy, the vessel lumen, and atherosclerotic lesions. Recent investigations on the application of cCTA in myocardial perfusion imaging suggest that cCTA may allow analysis of the hemodynamic relevance of detected stenosis. Data is accumulating that supports its relevance for patient management and outcome. This article examines the role of cCTA for the evaluation of plaques and stenosis.

    Hypnotherapy is an evidence based intervention for the treatment of functional bowel disorders, particularly irritable bowel syndrome. While similar in pathophysiology, less is known about the utility of hypnotherapy in the upper gastrointestinal tract. Esophageal disorders, most of which are functional in nature, cause painful and uncomfortable symptoms that impact patient quality of life and are difficult to treat from a medical perspective. After a thorough medical workup and a failed trial of proton pump inhibitor therapy, options for treatment are significantly limited. While the pathophysiology is likely multifactorial, two critical factors are believed to drive esophageal symptoms--visceral hypersensitivity and symptom hypervigilance. The goal of esophageal directed hypnotherapy is to promote a deep state of relaxation with focused attention allowing the patient to learn to modulate physiological sensations and symptoms that are not easily addressed with conventional medical intervention. Currently, the use of hypnosis is suitable for dysphagia, globus, functional chest pain/non-cardiac chest pain, dyspepsia, and functional heartburn. In this article the authors will provide a rationale for the use of hypnosis in these disorders, presenting the science whenever available, describing their approach with these patients, and sharing a case study representing a successful outcome.

    Single center experience with thoracoscopic repair of esophageal atresia with distal fistula and of tracheomalacia. Between May 2000 and December 2006, 51 neonates with an esophageal atresia were presented for thoracoscopic repair. Gestational age varied from 31 3/7 to 42 2/7 weeks (M = 37 2/7). Birth weight was between 1025 g and 4030 g (mean 2620 g). Concomitant anomalies or VACTERL association were encoutered in 31 patients (61%). Duration of the operation was from 90 minutes to 390 minutes (mean 178 minutes). All but 1 patient had an esophageal atresia with a distal fistula. Six patients had tracheomalacia requiring aortopexia, which was performed thoracoscopically. In 2 patients the thoracoscopic procedure had to be converted to a thoracotomy. All other patients underwent a successful thoracoscopic repair. One patient died in the postoperative period because of sepsis. A total of 22 patients (45%) developed a stenosis in the postoperative follow up (1 month-7y 7 month) requiring 1 to 18 dilatations (mean 1.5). Postoperative leakage occurred in 9 patients (18%). Recurrent fistula was encountered in 2 patients. A total of 11 patients (22%) underwent a laparoscopic antireflux procedure for either recurring stenosis (8) or ALTES (3). Six children (12%) underwent thoracoscopic aortopexy for tracheomalacia. In 2 children symptoms recurred for which a successful repeat thoracoscopic aortopexy was undertaken. The thoracoscopic approach to the treatment of esophageal atresia and tracheomalacia is becoming increasingly accepted. The cosmesis is undoubtedly better. The secundary effects like thoracic cage deformities, winged scapula, or scoliosis have not yet been described and are expected to be reduced in comparison to the open technique. Sequelae like leakage, stenosis, recurrent fistulae, and GERD and ALTES will probably remain the same. Whether thoracoscopic dissection has less detrimental effect on disturbed motility remains to be proven. Thoracoscopic aortopexy

    The Rome IV diagnostic criteria delineates 5 functional esophageal disorders which include functional chest pain, functional heartburn, reflux hypersensitivity, globus, and functional dysphagia. These are a heterogenous group of disorders which, despite having characteristic symptom profiles attributable to esophageal pathology, fail to demonstrate any structural, motility or inflammatory abnormalities on standard clinical testing. These disorders are associated with a marked reduction in patient quality of life, not least considerable healthcare resources. Furthermore, the pathophysiology of these disorders is incompletely understood. In this narrative review we provide the reader with an introductory primer to the structure and function of esophageal perception, including nociception that forms the basis of the putative mechanisms that may give rise to symptoms in functional esophageal disorders. We also discuss the provocative techniques and outcome measures by which esophageal hypersensitivity can be established.

    This study examines the scintigraphic transit pattern in a variety of esophageal disorders. Scintigraphy was performed with a semi solid bolus and the patient in an upright position. Condensed esophageal images were obtained from which we derived the esophageal transit time. The pattern of bolus transit was graded by the duration of transit and by the presence of hold up or retrograde motion. Scintigrams were performed in 11 volunteers and 88 patients whose esophageal function had been confirmed by conventional gastroesophageal techniques. Esophageal disorders examined included achalasia (20), scleroderma (9), esophageal carcinoma (8), Barrett esophagus (5), and reflux esophagitis (27). We also examined the effects of gastroesophageal surgery on esophageal function. Transit times distinguished grossly abnormal esophageal function from normal but did not distinguish between different esophageal disorders. Graded transit patterns were a more sensitive indicator of esophageal function and permitted some differentiation between esophageal disorders and allowed evaluation of the effects of gastroesophageal surgery.

    Esophageal motility disorders are classified primary and secondary, and primary esophageal motility disorders are classified esophageal achalasia and other diseases by manometry. An esophageal emptying disorder associated with insufficient relaxation of the lower esophageal sphincter (LES) and elimination of peristaltic waves on the esophageal body is the major abnormality of achalasia. Esophagogram, endoscopy, and manometry are used for diagnosis. As pharmacological therapy, administration of a calcium channel blocker or nitrate is useful. The pharmacological therapy is not recommended as long-term basic therapy but as a temporary treatment. At 1st, the balloon dilation method is chosen in treatment of achalasia Surgical treatment is indicated in the following cases: (1) Patients uneffected by balloon dilation, (2) Flask type with grade II to III dilation, and sigmoid type, (3) the gradual progression to the pathophysiological stage, (4) young patients, (5) complicated with esophageal cancer. Laparoscopic Heller-Dor procedure is the most popular surgical procedure, recently. It is somewhat difficult to perform surgical treatment for this functional disease. We should select the most suitable individualized treatment with efficient comprehension of the pathophysiological situation.

    Patients with resectable esophageal cancer often require placement of a surgical jejunostomy tube prior to receiving chemoradiation so as to maintain adequate nutrition due to their inability to swallow and eat. This study reports a single institutional experience with the Polyflex self-expanding silicone stent (Riisch; Kernen. Germany) in patients with malignant stenosis receiving chemoradiation prior to esophagectomy. This was a retrospective, nonrandomized study of 6 patients who underwent Polyflex esophageal stent placement across a malignant stricture prior to receiving neoadjuvant chemoradiation. The study assessed procedural success, restoration of oral nutrition, migration, and removal of the Polyflex stent. The outcomes measured were the efficacy of treatment, stent-related complications, and changes in the nutritional status of the patient after stent placement. Stent placement was successful in 5 of 6 patients (83%). Restoration of oral nutrition after stent placement occurred in 5 of 5 patients (100%). Migration of the stent into the stomach occurred in 3 patients (60%) without occurrence of gastric outlet obstruction; there was no proximal migration. Stents were successfully removed endoscopically or at the time of esophagectomy. This early experience suggests that the removable silicone Polyflex stent is an effective alternative to a surgical jejunostomy tube for the management of malignant esophageal stenosis in patients for whom neoadjuvant chemoradiation is planned prior to esophagectomy.

    Nutcracker esophagus (NE), Jackhammer esophagus (JHE), distal esophageal spasm (DES), and hypertensive lower esophageal sphincter (HTLES) are defined by esophageal manometric findings. Some patients with these esophageal motility disorders also have abnormal gastroesophageal reflux. It is unclear to what extent these patients' symptoms are caused by the motility disorder, the acid reflux, or both. The aim of this study was to determine the effectiveness of laparoscopic Nissen fundoplication (LNF) on esophageal motility disorders, gastroesophageal reflux, and patient symptoms. Between 2007 and 2013, we performed high-resolution esophageal manometry on 3400 patients, and 221 patients were found to have a spastic esophageal motility disorder. The medical records of these patients were reviewed to determine the manometric abnormality, presence of gastroesophageal symptoms, and amount of esophageal acid exposure. In those patients that underwent LNF, we compared pre- and postoperative esophageal motility, gastroesophageal symptom severity, and esophageal acid exposure. Of the 221 patients with spastic motility disorders, 77 had NE, 2 had JHE, 30 had DES, and 112 had HTLES. The most frequently reported primary and secondary symptoms among all patients were: heartburn and/or regurgitation, 69.2%; respiratory, 39.8%; dysphagia, 35.7%; and chest pain, 22.6%. Of the 221 patients, 192 underwent 24-hour pH monitoring, and 103 demonstrated abnormal distal esophageal acid exposure. Abnormal 24-hour pH monitoring was detected in 62% of patients with heartburn and regurgitation, 49% of patients with respiratory symptoms, 36.8 % of patients with dysphagia, and 32.6% of patients with chest pain. Sixty-six of the 103 patients with abnormal 24-hour pH monitoring underwent LNF. Thirty-eight (13NE, 2JHE, 6 DES, and 17 HTLES) of these 66 patients had a minimum of 6-month postoperative follow-up that included clinical evaluation, esophageal manometry, and 24-hour pH monitoring

    Post-intubation tracheal stenosis accounts for the greatest proportion of whole-cause tracheal stenosis. Treatment of post-intubation tracheal stenosis requires a multidisciplinary approach. Surgery or an endoscopic procedure can be used, depending on the type of stenosis. However, the efficacy of cryotherapy in post-intubation tracheal stenosis has not been validated. Here, we report a case of recurring post-intubation tracheal stenosis successfully treated with bronchoscopic cryotherapy that had previously been treated with surgery. In this case, cryotherapy was effective in treating web-like fibrous stenosis, without requiring more surgery. Cryotherapy can be considered as an alternative or primary treatment for post-intubation tracheal stenosis.

    When radiation therapy is used for palliation of obstruction in patients with advanced esophageal carcinoma, an improvement in dysphagia can be expected in approximately 50% of patients. Major objective responses have rarely been quantitied but, in one study, were seen in 33% patients. Recurrence of dysphagia is usually seen within 2-6 months of treatment. Radiation toxicities and complications, even when used with palliative intent, can be substantial and include esophagitis, tracheoesophageal or esophageal-aortic fistula, mediastinitis, hemorrhage, pneumonitis, and myelosuppression.

In the acute and subacute phases, the radiographic findings consisted of mucosal edema, submucosal edema or hemorrhage, ulcerations, sloughing of the mucosa, atony, and dilatation. Strictures of the esophagus were present in the chronic phase. These radiographic findings were not different from those found in alkaline corrosive esophagitis. The severity of the corrosive esophagitis is considered related to the concentration, amount, viscosity, and duration of contact between the caustic agent and the esophageal mucosa.

    Patients with gastroesophageal reflux disease (GERD) and disordered esophageal motility are at risk for postoperative dysphagia, and are often treated with partial (270-degree) fundoplication as a strategy to minimize postoperative swallowing difficulties. Complete (360-degree) fundoplication, however, may provide more effective and durable reflux protection over time. Recently we reported that postfundoplication dysphagia is uncommon, regardless of preoperative manometric status and type of fundoplication. To determine whether esophageal function improves after fundoplication, we measured postoperative motility in patients in whom disordered esophageal motility had been documented before fundoplication. Forty-eight of 262 patients who underwent laparoscopic fundoplication between 1995 and 2000 satisfied preoperative manometric criteria for disordered esophageal motility (distal esophageal peristaltic amplitude < or =30 mm Hg and/or peristaltic frequency < or =80%). Of these, 19 had preoperative manometric assessment at our facility and consented to repeat study. Fifteen (79%) of these patients had a complete fundoplication and four (21%) had a partial fundoplication. Each patient underwent repeat four-channel esophageal manometry 29.5 +/- 18.4 months (mean +/- SD) after fundoplication. Distal esophageal peristaltic amplitude and peristaltic frequency were compared to preoperative data by paired t test. After fundoplication, mean peristaltic amplitude in the distal esophagus increased by 47% (56.8 +/- 30.9 mm Hg to 83.5 +/- 36.5 mm Hg; P < 0.001) and peristaltic frequency improved by 33% (66.4 +/- 28.7% to 87.6 +/- 16.3%; P < 0.01). Normal esophageal motor function was present in 14 patients (74%) after fundoplication, whereas in five patients the esophageal motor function remained abnormal (2 improved, 1 worsened, and 2 remained unchanged). Three patients with preoperative peristaltic frequencies of 0%, 10%, and 20% improved to 84%, 88%, and 50%, respectively

    Esophageal lipomas are rare tumors, making up 0.4% of all digestive tract benign neoplasms. Most of these lesions are clinically silent as a result of their small size, however, the majority of lesions over 4 cm have been reported to cause dysphagia, regurgitation and/or epigastralgia. We report a case of a 53 year-old African American female who presented with dysphagia. Computed tomography of the chest and esophagram confirmed esophageal lipoma as the cause of the patient’s symptoms. Accurately diagnosing an esophageal lipoma is crucial in order to rule out potential malignant lesions, relieve patient symptoms and plan the appropriate treatment. PMID:23365708

    Synopsis This articles reviews the environmental risk factors and predisposing conditions for the two main histological types of esophageal cancer, esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EA). Tobacco smoking, excessive alcohol consumption, drinking maté, low intake of fresh fruits and vegetables, achalasia, and low socioeconomic status increase the risk of ESCC. Results of investigations on several other potential risk factors, including opium consumption, intake of hot drinks, eating pickled vegetables, poor oral health, and exposure to human papillomavirus, polycyclic aromatic hydrocarbons, N-nitroso compounds, acetaldehyde, and fumonisins are also discussed. Gastroesophageal reflux, obesity, tobacco smoking, hiatal hernia, achalasia, and probably absence of H. pylori in the stomach increase the risk of EA. Results of studies investigating other factors, including low intake of fresh fruits and vegetables, consumption of carbonated soft drink, use of H2 blockers, non-steroidal anti-inflammatory drugs, and drugs that relax the lower esophageal sphincter are also discussed.

    Radiation-induced esophagitis is the most common local acute toxicity of radiotherapy (RT) delivered for the curative or palliative intent treatment of lung cancer. Although concurrent chemotherapy and higher RT dose are associated with increased esophagitis risk, advancements in RT techniques as well as adherence to esophageal dosimetric constraints may reduce the incidence and severity. Mild acute esophagitis symptoms are generally self-limited, and supportive management options include analgesics, acid suppression, diet modification, treatment for candidiasis, and maintenance of adequate nutrition. Esophageal stricture is the most common late sequela from esophageal irradiation and can be addressed with endoscopic dilatation. Approaches to prevent or mitigate these toxicities are also discussed. PMID:28210168

  15. Uses of esophageal function testing: dysphagia.

    PubMed

    Yazaki, Etsuro; Woodland, Philip; Sifrim, Daniel

    2014-10-01

    Esophageal function testing should be used for differential diagnosis of dysphagia. Dysphagia can be the consequence of hypermotility or hypomotility of the muscles of the esophagus. Decreased esophageal or esophagogastric junction distensibility can provoke dysphagia. The most well established esophageal dysmotility is achalasia. Other motility disorders can also cause dysphagia. High-resolution manometry (HRM) is the gold standard investigation for esophageal motility disorders. Simultaneous measurement of HRM and intraluminal impedance can be useful to assess motility and bolus transit. Impedance planimetry measures distensibility of the esophageal body and gastroesophageal junction in patients with achalasia and eosinophilic esophagitis.

    Eosinophilic esophagitis, long known to be a feature of acid reflux, has recently been described in patients with food allergies and macroscopically furrowed esophagus. The pathophysiology and optimal management of patients with eosinophilic esophagitis is unclear. We describe our clinical experience related to eosinophilic esophagitis and obstructive symptoms in children and propose etiopathogenesis and management guidelines. Twelve children with obstructive esophageal symptoms (11 male), median age 5 years, and identified to have eosinophilic esophagitis with > 5 eosinophils per high-power field (eos/hpf) are reported. Of these, four had strictures, six had impactions, and two had only dysphagia. A diagnostic evaluation included esophagogastroduodenoscopy with biopsies in all and upper gastrointestinal series, IgE, radioallergosorbent tests, and skin tests for food allergies in some cases. Esophageal histology specimens were independently analyzed for eosinophil density by two authors. Four of five children with > 20 eos/hpf responded to elimination diets/steroids. The fifth child responded to a fundoplication. Seven children had 5-20 eos/hpf and three of them with no known food allergies responded to antireflux therapy alone. Three others in this group with positive food allergies responded to treatment with elimination diets and/or steroids. The seventh patient in this group was lost to follow-up. In conclusion, on the basis of response to therapy, eosinophilic esophagitis can be subdivided into two groups: those with likely gastroesophageal reflux disease if < 20 eos/hpf and no food allergies, and others with allergic eosinophilic esophagitis associated with food allergies and often with > 20 eos/hpf.

    Thermal injuries of the esophagus are rare causes of benign esophageal stricture, and all published cases were successfully treated with conservative management. A 28-year-old Japanese man with a thermal esophageal injury caused by drinking a cup of hot coffee six months earlier was referred to our hospital. The hot coffee was consumed in a single gulp at a party. Although the patient had been treated conservatively at another hospital, his symptoms of dysphagia gradually worsened after discharge. An upper gastrointestinal endoscopy and computed tomography revealed a pin-hole like area of stricture located 19 cm distally from the incisors to the esophagogastric junction, as well as circumferential stenosis with notable wall thickness at the same site. The patient underwent a thoracoscopic esophageal resection with reconstruction using ileocolon interposition. The pathological findings revealed wall thickening along the entire length of the esophagus, with massive fibrosis extending to the muscularis propria and adventitia at almost all levels. Treatment with balloon dilation for long areas of stricture is generally difficult, and stent placement in patients with benign esophageal stricture, particularly young patients, is not yet widely accepted due to the incidence of late adverse events. Considering the curability and quality-of-life associated with a long expected prognosis, we determined that surgery was the best treatment option for this young patient. In this case, we decided to perform an esophagectomy and reconstruction with ileocolon interposition in order to preserve the reservoir function of the stomach and to avoid any problems related to the reflux of gastric contents. In conclusion, resection of the esophagus is a treatment option in patients with benign esophageal injury, especially in cases involving young patients with refractory esophageal stricture. In addition, ileocolon interposition may help to improve the quality-of-life of patients. PMID

  18. Esophageal malignancy: A growing concern

    PubMed Central

    Chai, Jianyuan; Jamal, M Mazen

    2012-01-01

    Esophageal cancer is mainly found in Asia and east Africa and is one of the deadliest cancers in the world. However, it has not garnered much attention in the Western world due to its low incidence rate. An increasing amount of data indicate that esophageal cancer, particularly esophageal adenocarcinoma, has been rising by 6-fold annually and is now becoming the fastest growing cancer in the United States. This rise has been associated with the increase of the obese population, as abdominal fat puts extra pressure on the stomach and causes gastroesophageal reflux disease (GERD). Long standing GERD can induce esophagitis and metaplasia and, ultimately, leads to adenocarcinoma. Acid suppression has been the main strategy to treat GERD; however, it has not been proven to control esophageal malignancy effectively. In fact, its side effects have triggered multiple warnings from regulatory agencies. The high mortality and fast growth of esophageal cancer demand more vigorous efforts to look into its deeper mechanisms and come up with better therapeutic options. PMID:23236223

  19. Low-gradient aortic stenosis.

    PubMed

    Clavel, Marie-Annick; Magne, Julien; Pibarot, Philippe

    2016-09-07

    An important proportion of patients with aortic stenosis (AS) have a 'low-gradient' AS, i.e. a small aortic valve area (AVA <1.0 cm(2)) consistent with severe AS but a low mean transvalvular gradient (<40 mmHg) consistent with non-severe AS. The management of this subset of patients is particularly challenging because the AVA-gradient discrepancy raises uncertainty about the actual stenosis severity and thus about the indication for aortic valve replacement (AVR) if the patient has symptoms and/or left ventricular (LV) systolic dysfunction. The most frequent cause of low-gradient (LG) AS is the presence of a low LV outflow state, which may occur with reduced left ventricular ejection fraction (LVEF), i.e. classical low-flow, low-gradient (LF-LG), or preserved LVEF, i.e. paradoxical LF-LG. Furthermore, a substantial proportion of patients with AS may have a normal-flow, low-gradient (NF-LG) AS: i.e. a small AVA-low-gradient combination but with a normal flow. One of the most important clinical challenges in these three categories of patients with LG AS (classical LF-LG, paradoxical LF-LG, and NF-LG) is to differentiate a true-severe AS that generally benefits from AVR vs. a pseudo-severe AS that should be managed conservatively. A low-dose dobutamine stress echocardiography may be used for this purpose in patients with classical LF-LG AS, whereas aortic valve calcium scoring by multi-detector computed tomography is the preferred modality in those with paradoxical LF-LG or NF-LG AS. Although patients with LF-LG severe AS have worse outcomes than those with high-gradient AS following AVR, they nonetheless display an important survival benefit with this intervention. Some studies suggest that transcatheter AVR may be superior to surgical AVR in patients with LF-LG AS.

    Purpose: This study was designed to evaluate our experience with the treatment of postoperative anastomotic leaks and benign esophageal perforations with covered biodegradable stents. Materials and Methods: From 2008 to 2010, we treated five men with either an anastomotic leak or benign esophageal perforation by implanting of covered biodegradable Ella-BD stents. The average age of the patients was 60 (range, 38-74) years. Postoperative anastomotic leaks were treated in four patients (1 after esophagectomy, 1 after resection of diverticulum, 2 after gastrectomy). In one patient, perforation occurred as a complication of the treatment of an esophageal rupture (which occurred during a balloon dilatation of benign stenosis) with a metallic stent. Results: Seven covered biodegradable stents were implanted in five patients. Primary technical success was 100%. Clinical success (leak sealing) was achieved in four of the five patients (80%). Stent migration occurred in three patients. In two of these patients, the leak had been sealed by the time of stent migration, therefore no reintervention was necessary. In one patient an additional stent had to be implanted. Conclusion: The use of biodegradable covered stents for the treatment of anastomotic leaks or esophageal perforations is technically feasible and safe. The initial results are promising; however, larger number of patients will be required to evaluate the capability of these biodegradable stents in the future. The use of biodegradable material for coverage of the stent is essential.

  7. Efficacy and complication of endoscopic submucosal dissection for superficial esophageal carcinoma: a systematic review and meta-analysis

    2014-01-01

    Aim For patients with superficial esophageal carcinoma, ESD was one of treatment modalities to remove the lesion safely and effectively. We perform this meta-analysis to determine the efficacy and incidence of complication of ESD for patients with superficial esophageal carcinoma. Method Articles were searched in MEDLINE (PubMed and Ovid), Cochrane Database of Systemic Reviews, Google scholar, and Web of Science. Two reviewers independently searched and extracted data. Meta-analysis of the efficacy of ESD was analyzed by calculating pooled en bloc and R0 resection rate. Incidence of complications such as perforation, stenosis and mediastinal emphysema was also calculated. Pooling was conducted using either fixed-effects model or random-effects model depending on the heterogeneity across studies. Results 21 studies (1152 patients and 1240 lesions) were included in this analysis. The pooled en bloc resection rate was 99% (95% CI 99%-100%). Stratified by tumor size, en bloc resection rates did not show any significant difference. The pooled R0 resection rate was 90% (95% CI 87%-93%). The pooled R0 resection rate was 85% (95% CI, 80%-90%) for large tumor and 92% (95% CI, 87%-93%) for small tumor (p < 0.001). Stenosis served as the most common reported complication with pooled incidence of 5% (95% CI 3-8%), followed by perforation (1%, 95% CI 0-1%) and mediastinal emphysema (0% CI 0-1%). The incidence of postoperative stenosis decreased significantly after 2011 (2%, 95% CI 0-3%) compared with that before 2011 (9%, 95% CI 3-8%) (p < 0.001). Conclusion ESD was an efficient modality for treating superficial esophageal carcinoma, with perfect en bloc and R0 resection rate and low complication rate. The most common complication of ESD was stenosis. Although recurrence rate was low, patients should be maintained in a scheduled surveillance program. PMID:24885614

    Esophageal pain that manifests as heartburn or chest pain, is a prevalent problem. Esophageal chest pain is most often caused by gastroesophageal reflux disease (GERD), but can also result from inflammatory processes, infections involving the esophagus, and contractions of the esophageal muscle. The mechanisms and pathways of esophageal chest pain are poorly understood. Vagal and spinal afferent pathways carry sensory information from the esophagus. Recently, esophageal hypersensitivity is identified as an important factor in the development of esophageal pain. A number of techniques are available to evaluate esophageal chest pain such as endoscopy and/or proton-pump inhibitor trial, esophageal manometry, a combined impedance-pH study, and esophageal ultrasound imaging. Proton pump inhibitors (PPIs) have the huge success in the treatment of GERD. Other drugs such as imipramine, trazadone, sertraline, tricyclics, and theophylline have been introduced for the control of esophageal chest pain in partial responders to PPI and the patients with esophageal hypersensitivity. Novel drugs which act on different targets are anticipated to treat esophageal pain in the future.

    Opportunistic esophageal infections (Candida, cytomegalovirus, herpes simplex virus) and idiophatic esophageal ulcerations are commonly found in HIV patients. However, motility disorders of the esophagus have seldom been investigated in this population. The aim of this prospective study was to determine the presence of motility disorders in HIV patients with esophageal symptoms (with or without associated lesions detected by endoscopy) and in HIV patients without esophageal symptoms and normal esophagoscopy. Eigthteen consecutive HIV patients (10 male, 8 female, ages 20-44 years, mean age 33.5; 8 HIV positive and 10 AIDS) were studied prospectively. Nine patients complained of esophageal symptoms, e.g, dysphagia/odynophagia (group 1) and 9 had symptoms not related to esophageal disease, such as diarrhea, abdominal pain, or gastrointestinal bleeding (group 2). All patients underwent upper endoscopy; mucosal biopsies were taken when macroscopic esophageal lesions were identified or when the patients were symptomatic even if the esophageal mucosa was normal. Esophageal manometry was performed in the 18 patients, using a 4-channel water-perfused system according to a standardized technique. Sixteen of the 18 patients (88.8%) had baseline manometric abnormalities. In group 1, 8/9 patients had esophageal motility disorders: nutcrackeresophagus in 1, hypertensive lower esophageal sphincter (LES) with incomplete relaxation in 2, nonspecific esophageal motility disorders (NEMD) in 3, diffuse esophageal spasm in 1, esophageal hypocontraction with low LES pressure in 1. Six of these 9 patients had lesions detected by endoscopy: CMV ulcers in 2, idiopathic ulcers in 1, candidiasis in 1, idiopathic ulcer + candidiasis in 1, nonspecific esophagitis in 1; and 3/9 had normal endoscopy and normal esophageal biopsies. In group 2, 8/9 patients had abnormal motility: hypertensive LES with incomplete relaxation in 1, nutcracker esophagus in 2, esophageal hypocontraction in 3, and NEMD

    At Digestive Disease Week (DDW) 2014, developments in esophageal disease were presented. Highlights include: the usefulness of impedancemetry to diagnose reflux disease, or the effectiveness of PPIs for treating non-cardiac chest pain. Concerning Barrett's esophagus, its prevalence is identical in patients with and without reflux symptoms, Barrett segments less than 1cm probably do not require follow-up, and in older patients with long-segment Barrett, initial endoscopies overlooked up to 2% of significant lesions. Regarding achalasia, surgical myotomy is no more effective than endoscopic dilation and may even be less effective than peroral endoscopic myotomy (POEM). In terms of eosinophilic esophagitis, it is important to systematically take biopsies in patients with dysphagia so that cases of eosinophilic esophagitis are not overlooked. In addition, for this condition, routine endoscopic dilations not only do not seem useful in improving the course of the disease, but could also worsen the response to medical treatment.

  15. Hemodynamics of Curved Vessels with Stenosis

    NASA Astrophysics Data System (ADS)

    Boghosian, Michael E.; Cassel, Kevin W.

    2007-11-01

    In hemodialysis access, the brachiocephalic or upper-arm fistula has less than optimal functional rates. The cause of this reduced patency is stenosis due to intimal hyperplasia in the cephalic vein. Stenosis typically leads to thrombosis and ultimately failure of the fistula. To increase our understanding of this process, numerical simulations of the unsteady, two-dimensional, incompressible Navier-Stokes equations are solved for the flow in an infinite channel having curvature and stenosis. Physiologically relevant Reynolds numbers ranging from 300 to 1500 and stenosis percentages of 0, 25, 50, and 75 are modeled. The post-stenotic flow is characterized by strong shear layers and recirculation regions. The largest shear stresses are found just upstream of the stenosis apex. The maximum shear stress increases with increasing Reynolds number and percent stenosis. The results indicate that hemodynamic conditions in the vein after fistula creation combined with curvature of the cephalic arch lead to shear stresses that exceed normal physiological values (both minimum and maximum). In some cases, the shear stresses are sufficiently large to cause damage to the endothelium and possibly denudation.

    Abstract Introduction: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by a marked eosinophilic infiltrate in the esophageal mucosa. What was once considered a rare disease has nowadays become one of the most frequent esophageal diseases in the Western countries, occupying a place just next to the gastroesophageal reflux disease. EoE etiology and pathogenesis remain largely unknown, although most studies consider that allergic and genetic factors play the most important role. Methods: We report the case of EoE in an elderly male (octogenarian), giving a brief review of the current data related to epidemiology, pathogenesis, diagnosis, and treatment of the disease. Results: Dysphagia to solid foods was the leading symptom, and endoscopic findings included white exudates, longitudinal furrows, and concentric mucosal rings, all suggestive for EoE. Diagnosis relied on histological findings in esophageal mucosal biopsies (>30 eosinophils per high power field). He was treated with topical steroids for 8 weeks, symptoms improved gradually and the patient remained in remission at the 8-month follow-up. Conclusion: This case emphasizes that EoE may occur in very old patients and gastroenterologists should have a high index of suspicion of this disorder in any elderly with dysphagia and endoscopic relevant features.

    2014-01-01

    Eosinophilic esophagitis (EoE) is an emerging disease characterized by esophageal eosinophilia (>15eos/hpf), lack of responsiveness to acid-suppressive medication and is managed by allergen elimination and anti-allergy therapy. Although the pathophysiology of EoE is currently unsubstantiated, evidence implicates food and aeroallergen hypersensitivity in genetically predisposed individuals as contributory factors. Genome-wide expression analyses have isolated a remarkably conserved gene-expression profile irrespective of age and gender, suggesting a genetic contribution. EoE has characteristics of mainly TH2 type immune responses but also some TH1 cytokines, which appear to strongly contribute to tissue fibrosis, with esophageal epithelial cells providing a hospitable environment for this inflammatory process. Eosinophil-degranulation products appear to play a central role in tissue remodeling in EoE. This remodeling and dysregulation predisposes to fibrosis. Mast-cell-derived molecules such as histamine may have an effect on enteric nerves and may also act in concert with transforming growth factor-β to interfere with esophageal musculature. Additionally, the esophageal epithelium may facilitate the inflammatory process under pathogenic contexts such as in EoE. This article aims to discuss the contributory factors in the pathophysiology of EoE.

    2015-01-01

    Aortic stenosis (AS) occurs in almost 10% of adults over age 80 years with a mortality about 50% at 2 years unless outflow obstruction is relieved by aortic valve replacement (AVR). Development of AS is associated with anatomic, clinical and genetic risk factors including a bicuspid valve in 50%; clinical factors that include older age, hypertension, smoking, diabetes and elevated serum lipoprotein(a) [Lp(a)] levels; and genetic factors such as a polymorphism in the Lp(a) locus. Early stages of AS are characterized by focal areas of leaflet thickening and calcification. The rate of hemodynamic progression is variable but eventual severe AS is inevitable once even mild valve obstruction is present. There is no specific medical therapy to prevent leaflet calcification. Basic principles of medical therapy for asymptomatic AS are patient education, periodic echocardiographic and clinical monitoring, standard cardiac risk factor evaluation and modification and treatment of hypertension or other comorbid conditions. When severe AS is present, a careful evaluation for symptoms is needed, often with an exercise test to document symptom status and cardiac reserve. In symptomatic patients with severe AS, AVR improves survival and relieves symptoms. In asymptomatic patients with severe AS, AVR also is appropriate if ejection fraction is < 50%, disease progression is rapid or AS is very severe (aortic velocity > 5 m/s). The choice of surgical or transcatheter AVR depends on the estimated surgical risk plus other factors such as frailty, other organ system disease and procedural specific impediments. PMID:26140146

    Background. The relation of esophageal food bolus impaction (FBI) to eosinophilic esophagitis (EoE) and lymphocytic esophagitis (LyE) is unclear. The aim of this study was to determine the prevalence of EoE and LyE among adults with FBI. Methods. In this retrospective study we analyzed data from all patients referred for gastroscopy during the past 5 years, because of a present or recent episode of FBI. Results. We found 238 patients with FBI (median age 51 (17–96), 71% males). Endoscopic therapy was required in 143 patients. Esophageal biopsies were obtained in 185 (78%) patients. All biopsies were assessed for numbers of eosinophils and lymphocytes. EoE was found in 18% of patients who underwent biopsy. We found 41 patients (22%) who fulfilled the criteria for both EoE and LyE (EoE/LyE). LyE was found in the 9% of patients with FBI. EoE together with EoE/LyE was the leading cause of FBI in patients ≤50 years (64%). GERD was the leading cause of FBI among patients older than 50 years (42%). Conclusions. Our study showed that EoE was the leading cause of FBI in particular among young adults. Our study highlights the need for esophageal biopsies in any patient with FBI. PMID:27547221

We found 41 patients (22%) who fulfilled the criteria for both EoE and LyE (EoE/LyE). LyE was found in the 9% of patients with FBI. EoE together with EoE/LyE was the leading cause of FBI in patients ≤50 years (64%). GERD was the leading cause of FBI among patients older than 50 years (42%). Conclusions. Our study showed that EoE was the leading cause of FBI in particular among young adults. Our study highlights the need for esophageal biopsies in any patient with FBI.

    History | A 77-year-old woman was admitted with severe chest pain, heartburn, dysphagia and odynophagia. She had been on dabigatran for 13 months due to atrial fibrillation and arterial hypertension. Investigations and findings | Endoscopy of the esophagus revealed sloughing of mucosal casts, predominantly in the upper half of the organ. Treatment and course | The patient was placed on pantoprazol, local anaesthetic antacid and i. v. fluids. Dabigatran was discontinued. The symptoms disappeared within 3 days. Control endoscopy after 12 days showed complete healing of the esophageal mucosa. Conclusion | The intake of dabigatran was associated with exfoliative esophagitis, possibly due to caustic tissue damage by prolonged drug contact.

    Objective Laryngotracheal stenosis is largely considered a structural entity, defined on anatomic terms (i.e. percent stenosis, distance from vocal folds, overall length). This has significant implications for identifying at-risk populations, devising systems-based preventive strategies, and promoting patient-centered treatment. The present study was undertaken to test the hypothesis that LTS is heterogeneous in regard to etiology, natural history, and clinical outcome. Study Design Retrospective cohort study of consecutive adult tracheal stenosis patients from 1998–2013. Methods Subjects diagnosed with laryngotracheal stenosis (ICD-9: 478.74, 519.19) between January 1, 1998 and January 1, 2013 were identified. Patient characteristics (age, gender, race, follow-up duration), and comorbidities were extracted. Records were reviewed for etiology of stenosis, treatment approach, and surgical dates. Stenosis morphology was derived from intraoperative measurements. The presence of tracheostomy at last follow-up was recorded. Results 150 patients met inclusion criteria. 54.7% had an iatrogenic etiology followed by idiopathic (18.5%), autoimmune (18.5%), and traumatic (8%). Tracheostomy dependence differed based on etiology (p<0.001). Significantly more patients with iatrogenic (66%) and autoimmune (54%) etiologies remained tracheostomy dependent compared to traumatic (33%) or idiopathic (0%) groups. On multivariate regression analysis, each additional point on Charlson Comorbidity Index was associated with a 67% increased odds of tracheostomy dependence (OR 1.67, 95% CI 1.04 – 2.69; p=0.04). Conclusions Laryngotracheal stenosis is not a homogeneous clinical entity. It has multiple distinct etiologies that demonstrate disparate rates of long-term tracheostomy dependence. Understanding the mechanism of injury and contribution of comorbid illnesses is critical to systems-based preventive strategies and patient-centered treatment. PMID:25290987

    The goal of this article is to present the results of the long-term treatment with esophageal dilation of a consecutive series of adults with eosinophilic esophagitis (EoE). EoE in adults is a disease of middle aged white males, with recurrent food impactions and dysphagia. The exact treatment of EoE is unknown due to the uncertainty of the pathogenesis. Currently, the long-term follow-up of adult EoE patients is limited. Sixteen consecutive adult patients (12 males/4 females between ages 27 and 58 years) with EoE underwent a detailed history and baseline upper gastrointestinal endoscopy (EGD) with multiple esophageal biopsies. Thirteen had esophageal dilation. Fifteen were on proton pump inhibitor (PPI) therapy. After dilation, one patient was treated with a restrictive diet. One patient took prn fluticasone. Most of the patients had allergy testing for food and aeroallergens. Follow-up evaluation with similar testing was on average 22 months (range: 12-40 months). Six patients were not available for follow-up. None of the remaining 10 patients had a food impaction; one required further esophageal dilation. Only two patients had intermittent dysphagia. The average dysphagia score decreased from 2.1 to 0.3 (P < 0.002). The average number of eosinophils at follow-up was not significantly different from baseline (120 eosinophils/HPF proximally and 165 eosinophils/HPF distally (P= 0.75). The gross endoscopy findings were unchanged in all patients except one who normalized. A total of 62% and 75% of patients had positive tests for aeroallergens and food allergens, respectively. Over an average of two years, esophageal dilation provided excellent symptomatic relief among 10 adult EoE patients despite no improvement in the mucosal eosinophilia or gross endoscopic appearance.

    Esophageal atresia (EA) is defined as a discontinuity of the lumen of the esophagus repaired soon after birth. Dysphagia is a common symptom in these patients, usually related to stricture, dysmotility or peptic esophagitis. We present 4 cases of patients with EA who complained of dysphagia and the diagnosis of Eosinophilic esophagitis (EoE) was made, ages ranging from 9 to 16 years. Although our patients were on acid suppression years after their EA repair, they presented with acute worsening of dysphagia. Esophogastroduodenoscopy and/or barium swallow did not show stricture and biopsies revealed elevated eosinophil counts consistent with EoE. Two of 4 patients improved symptomatically with the topical steroids. It is important to note that all our patients have asthma and 3 out of 4 have tested positive for food allergies. One of our patients developed recurrent anastomotic strictures that improved with the treatment of the EoE. A previous case report linked the recurrence of esophageal strictures in patients with EA repair with EoE. Once the EoE was treated the strictures resolved. On the other hand, based on our observation, EoE could be present in patients without recurrent anastomotic strictures. There appears to be a spectrum in the disease process. We are suggesting that EoE is a frequent concomitant problem in patients with history of congenital esophageal deformities, and for this reason any of these patients with refractory reflux symptoms or dysphagia (with or without anastomotic stricture) may benefit from an endoscopic evaluation with biopsies to rule out EoE.

    Background: The long-term success of bariatric operations for weight reduction has been well documented, but their potential effects on the risk of esophageal cancer have not been evaluated. Methods: We performed operations on 3 patients for esophageal cancer following bariatric operations: 2 had Roux-en-Y gastric bypass, and 1 underwent vertical banded gastroplasty. All of these patients had adenocarcinoma at the gastroesophageal junction; 1 involved the entire intrathoracic esophagus. Results: The intervals between the weight-loss operations and cancer diagnoses were 21, 16, and 14 years. All 3 patients had symptoms of reflux for many years before dysphagia developed and cancer was diagnosed. We performed a limited esophagogastrectomy, a classic IvorLewis procedure, and a total esophagectomy with jejunal free-tissue transfer from stomach to cervical esophagus. Two patients had positive lymph nodes. One patient is alive at 6 years; 2 died at 13 and 15 months after undergoing operation for recurrent cancer. Conclusion: The effect of bariatric operations on gastroesophageal reflux is not known, although gastric bypass has been advocated as the “ultimate antireflux procedure.” The presence of esophageal cancer in these 3 patients years after the weight loss operation is worrisome. We believe that patients who develop new symptoms should have endoscopic evaluation and that epidemiologic studies on the incidence of esophageal cancer occurring years after bariatric operation should be performed.

    2017-01-01

    Background/Aims Esophageal dysmotility is associated with gastrointestinal dysmotility in various systemic and neuroregulatory disorders. Hypothyroidism has been reported to be associated with impaired motor function in esophagus due to accumulation of glycosaminoglycan hyaluronic acid in its soft tissues, leading to changes in various contraction and relaxation parameters of esophagus, particularly in the lower esophageal sphincter. In this study we evaluated esophageal transit times in patients of primary hypothyroidism using the technique of radionuclide esophageal transit scintigraphy. Methods Thirty-one patients of primary hypothyroidism and 15 euthyroid healthy controls were evaluated for esophageal transit time using 15–20 MBq of Technetium-99m sulfur colloid diluted in 10–15 mL of drinking water. Time activity curve was generated for each study and esophageal transit time was calculated as time taken for clearance of 90% radioactive bolus from the region of interest encompassing the esophagus. Esophageal transit time of more than 10 seconds was considered as prolonged. Results Patients of primary hypothyroidism had a significantly increased mean esophageal transit time of 19.35 ± 20.02 seconds in comparison to the mean time of 8.25 ± 1.71 seconds in healthy controls (P < 0.05). Esophageal transit time improved and in some patients even normalized after treatment with thyroxine. A positive correlation (r = 0.39, P < 0.05) albeit weak existed between the serum thyroid stimulating hormone and the observed esophageal transit time. Conclusions A significant number of patients with primary hypothyroidism may have subclinical esophageal dysmotility with prolonged esophageal transit time which can be reversible by thyroxine treatment. Prolonged esophageal transit time in primary hypothyroidism may correlate with serum thyroid stimulating hormone levels. PMID:27444283

    Percutaneous transcatheter tricuspid balloon valvuloplasty (PTTBV) is an accepted treatment option for symptomatic severe native tricuspid valve stenosis, although surgical tricuspid valve replacement remains the treatment of choice. There have been few reports of successful PTTBV for bioprosthetic tricuspid valve stenosis. We present case reports of 3 patients from our hospital experience. Two of the 3 cases were successful, with lasting clinical improvement, whereas the 3rd patient failed to show a reduction in valve gradient. We describe the standard technique used for PTTBV. We present results from a literature review that identified 16 previously reported cases of PTTBV for bioprosthetic severe tricuspid stenosis, with overall favorable results. We conclude that PTTBV should perhaps be considered for a select patient population in which symptomatic improvement and hemodynamic stability are desired immediately, and particularly for patients who are inoperable or at high surgical risk.

Case 2, which involved a 1-year-old neutered male Norwegian Forest cat, and Case 3, which involved a 6-month-old intact female American Curl cat, were referred, because of cardiac murmurs. Grades III to IV/VI systolic heart murmurs were auscultated at the left heart base in all 3 cats. All cases showed bilateral pulmonary artery stenosis, although there were no associated clinical signs. In Cases 1 and 2, the pressure gradient through the stenosis decreased after treatment with atenolol. PMID:25650057

    Acquired vaginal stenosis is a rare obstructing anomaly, which can be caused by use of chemicals in the vagina. A 21-year-old gravida 1 para 1, presented with secondary amenorrhea and inability to have sexual intercourse, after normal spontaneous vaginal delivery complicated by post partum bleeding. The delivery was conducted by untrained traditional birth attendant at home. The wash cloth soaked with caustic soda was packed in the patient’s vagina and was left in situ for 10 days, which ultimately led to the severe scarring and stenosis of the vagina. Patient underwent surgical management and the extensive vaginal adhesions were excised and a patent vagina was reconstructed. Patient then reported successful vaginal intercourse without dyspareunia. Post partum vaginal stenosis due to chemical vaginitis is rare. These cases can be prevented by adequate training of untrained health care workers. PMID:27437311

    Coronary ostial stenosis is a rare but potentially serious sequela after aortic valve replacement. It occurs in the left main or right coronary artery after 1% to 5% of aortic valve replacement procedures. The clinical symptoms are usually severe and may appear from 1 to 6 months postoperatively. Although the typical treatment is coronary artery bypass grafting, patients have been successfully treated by means of percutaneous coronary intervention. Herein, we present the cases of 2 patients in whom coronary ostial stenosis developed after aortic valve replacement. In the 1st case, a 72-year-old man underwent aortic valve replacement and bypass grafting of the saphenous vein to the left anterior descending coronary artery. Six months later, he experienced a non-ST-segment-elevation myocardial infarction. Coronary angiography revealed a critical stenosis of the right coronary artery ostium. In the 2nd case, a 78-year-old woman underwent aortic valve replacement and grafting of the saphenous vein to an occluded right coronary artery. Four months later, she experienced unstable angina. Coronary angiography showed a critical left main coronary artery ostial stenosis and occlusion of the right coronary artery venous graft. In each patient, we performed percutaneous coronary intervention and deployed a drug-eluting stent. Both patients were asymptomatic on 6-to 12-month follow-up. We attribute the coronary ostial stenosis to the selective ostial administration of cardioplegic solution during surgery. We conclude that retrograde administration of cardioplegic solution through the coronary sinus may reduce the incidence of postoperative coronary ostial stenosis, and that stenting may be an efficient treatment option.

    Pulmonary vein stenosis is a rare progressive narrowing of the extrapulmonary pulmonary veins, presenting predominantly in infancy and virtually always lethal. It typically arises following repair of congenital heart disease, particularly anomalous pulmonary venous return. Histologic characterization of pediatric pulmonary vein stenosis, not previously well described, may provide insight into the disease pathobiology. We retrieved archival lung specimens (biopsy, explant, or autopsy) from patients with pediatric pulmonary vein stenosis. Medical records were reviewed. Microscopic examination included hematoxylin and eosin (H&E)-stained slides, and for a subset of patients, elastic, trichrome, smooth-muscle actin, and D2-40. Groups with different clinical disease features were compared using Fisher's exact test. A total of 33 patients (median age, 7 months) had available tissue and 52% had congenital heart disease; 18% were premature. Within the lungs, interlobular septal veins showed thickened muscular coats (in 58%), proliferation/tortuosity (in 6%), and fibromyxoid intimal proliferation (in 3%). Associated arterial hypertensive changes were seen in 30 (91%). The one patient with intrapulmonary venous fibromyxoid intimal proliferation was the only patient with apparent primary familial disease. Lymphangiectasia and arterial medial hypertrophy were histologic features that correlated with clinical grouping. We conclude that in pediatric pulmonary vein stenosis, intrapulmonary pulmonary veins commonly show muscular thickening, best interpreted as venous hypertensive remodeling. Fibromyxoid intimal proliferation resembling that of the extrapulmonary pulmonary veins is uncommon. Awareness of intrapulmonary features in various clinical subtypes of pulmonary vein stenosis may be diagnostically and therapeutically informative considering that current catheter-based and surgical therapy is directed at the extrapulmonary component of pulmonary vein stenosis.

    The natural history of chronic radiation esophagitis occurring in previously normal esophagus is still unknown. The authors describe here the long-term outcome of chronic esophagitis arising after neck irradiation for oropharynx and larynx carcinomas in 13 consecutive adult patients. The first clinical signs of radiation esophagitis were dysphagia or impossibility of oral intake, which appeared within 26 months (range 2--120 months) after the end of radiation for pyriform fossae carcinoma (N = 5), tonsil carcinoma (N = 2), larynx carcinoma (N = 2), pharynx carcinoma (N = 2), base of the tongue (N = 1), and thyroid carcinomas (N = 1). During upper endoscopy, an esophageal stenosis was found in 11 cases and was associated with ulceration in three cases. An isolated esophageal ulceration was present in only two cases. Chronic radiation esophagitis diagnosis was confirmed by histology and surgery in seven cases. In the last six cases, diagnosis was supported by the absence of first cancer relapses within a median follow-up of two years (16 months to nine years) and by endoscopic findings. Seven patients received parenteral or enteral nutrition. Ten patients were treated by peroral dilatations. These treatments allowed nearly normal oral diet in 11/13 patients. Only one patient was lost of follow-up after 20 months. Four patients died from chronic radiation esophagitis. One of these patients died from massive hemorrhage after peroral dilatation. Four patients died of a second carcinoma with no first cancer recurrence. Four patients were alive after six months to nine years of follow-up. Moderate dysphagia was still present, allowing nearly normal oral feeding. In conclusion, chronic radiation esophagitis is a severe disease with an underestimated frequency. In this study, peroral dilatations appeared to be necessary and were not associated with an increased morbidity. 21 refs., 1 tab.

    Post-intubation tracheal stenosis accounts for the greatest proportion of whole-cause tracheal stenosis. Treatment of post-intubation tracheal stenosis requires a multidisciplinary approach. Surgery or an endoscopic procedure can be used, depending on the type of stenosis. However, the efficacy of cryotherapy in post-intubation tracheal stenosis has not been validated. Here, we report a case of recurring post-intubation tracheal stenosis successfully treated with bronchoscopic cryotherapy that had previously been treated with surgery. In this case, cryotherapy was effective in treating web-like fibrous stenosis, without requiring more surgery. Cryotherapy can be considered as an alternative or primary treatment for post-intubation tracheal stenosis. PMID:27853078

    This paper presents an update on degenerative stenosis of the lumbar spine, which is a common pathological condition among patients over the age of 65 years. The anamnesis and physical examination need to be precise, since radiography often only provides indirect signs. Magnetic resonance imaging is necessary if the symptoms persist. The treatment for lumbar stenosis is a matter of controversy. However, there seems to be some benefit from surgical treatment rather than conservative treatment, such that surgery brings improvements in symptoms and functions for a period of up to two years.

    Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation. PMID:26229836

    Supravalvular aortic stenosis as a late complication of transposition of the great arteries is very rare, and only a few cases have been reported. We describe the case of a 14-year-old girl who developed supravalvular aortic stenosis as a late complication of the arterial switch operation for transposition of the great arteries. The narrowed ascending aorta was replaced with a graft. The right pulmonary artery was transected to approach the ascending aorta which adhered severely to the main pulmonary trunk, and we obtained a good operative field.

    Esophageal perforation is a difficult problem in thoracic surgery. Esophageal perforations can be spontaneous, iatrogenic, or malignant. We report two cases of esophageal perforations caused by thoracic osteophytes and different management strategies leading to successful outcomes. An 80-year-old male presented with chest pain and dysphagia following a fall. On endoscopy, an esophageal perforation and foreign body was noted which was confirmed as a thoracic osteophyte on computed tomography scan. He was managed conservatively as he declined surgery. A 63-year-old male was admitted with dysphagia following a food bolus obstruction. Following esophagoscopy and dilatation, there was clinical and radiological evidence of perforation. During surgery, a thoracic osteophyte was identified as the cause of perforation. The perforation was closed in layers and the osteophyte was trimmed. Both patients recovered well. Thoracic osteophytes are a rare cause of esophageal perforations and a high index of suspicion is required in patients with osteoarthritis who present with esophageal perforations.

    Background: Thoracoscopic treatment of esophageal atresia and tracheoesophageal fistula (EA+TEF) is accepted as a superior technique at least in cosmetic point of view but it is considered as an advance endoscopic procedure that needs a learning curve to be performed perfectly. This is the first report of Iranian group pediatric surgeons in thoracoscopic approach to EA. Methods and Materials: Since 2010, twenty four cases with EA+TEF underwent thoracoscopic approach in Sarvar Children Hospital (Mashhad -Iran). During the first 6 months, thoracoscopic approach to 6 cases of EA+TEF was converted to open procedure because of technical and instrumental problems. The first case of successful thoracoscopic EA repair was accomplished in 2010 and since then, 10 cases of EA+ TEF among 18 patients were treated successfully with thoracoscopic approach Results: Overall conversion rate was 58.3% but conversion rate after the primary learning curve period, was 35.7%. The main conversion causes include difficulties in esophageal anastomosis, limited exposure and deteriorating the patient's condition. Anastomotic leak and stenosis were observed in 20% and 40% respectively. Overall mortality rate was 4.2%. Conclusion: Thoracoscopic repair of esophageal atresia seems feasible and safe with considerable superiorities to the conventional method although acceptable results needs a prolonged learning curve and advanced endoscopic surgical skill. Clear judgment about the best surgical intervention for EA according to all cosmetic and functional outcomes needs further studies. PMID:27471677

    This study reports the case of a 44-year-old woman with oral oxalic acid poisoning. As the illness progressed, the patient exhibited severe metabolic acidosis, large-area esophageal mucosa injury and acute kidney injury, which required dialysis. A guide wire slipped out of position during the process of hemodialysis and moved back and forth in the veins, but was removed successfully by interventional endovascular treatment. However, the patient's esophageal mucosa exfoliated, which lead to severe benign esophageal stenosis and dysphagia. Balloon distention was conducted twice in the upper digestive tract using X-ray location in combination with a dumb-bell bladder and interventional wire. The patient exhibited convulsions, shock, embolism and loss of consciousness while undergoing the second balloon distention procedure. Following symptomatic treatment, the patient eventually remained in a stable condition, the digestive tract expansion procedure was not resumed and a jejunostomy was performed in order to facilitate enteral nutrition, which was administered via the jejunum and had little stimulatory effect on the pancreas. Following various treatments, the patient's condition improved markedly, with renal function returning to normal. PMID:26889241

    Background: Long-term patency is required during treatment for benign airway stenosis. This study investigated the effectiveness of surgical airway plasty for benign airway stenosis. Methods: Clinical courses of 20 patients, who were treated with surgical plasty for their benign airway stenosis, were retrospectively investigated. Results: Causes of stenosis were tracheobronchial tuberculosis in 12 patients, post-intubation stenosis in five patients, malacia in two patients, and others in one patient. 28 interventional pulmonology procedures and 20 surgical plasty were performed. Five patients with post-intubation stenosis and four patients with tuberculous stenosis were treated with tracheoplasty. Eight patients with tuberculous stenosis were treated with bronchoplasty, and two patients with malacia were treated with stabilization of the membranous portion. Anastomotic stenosis was observed in four patients, and one to four additional treatments were required. Performance status, Hugh–Jones classification, and ventilatory functions were improved after surgical plasty. Outcomes were fair in patients with tuberculous stenosis and malacia. However, efficacy of surgical plasty for post-intubation stenosis was not observed. Conclusion: Surgical airway plasty may be an acceptable treatment for tuberculous stenosis. Patients with malacia recover well after surgical plasty. There may be untreated patients with malacia who have the potential to benefit from surgical plasty. PMID:26567879

    Esophageal achalasia is a primary esophageal motility disorder characterized by lack of peristalsis and a lower esophageal sphincter that fails to relax appropriately in response to swallowing. This article summarizes the most salient issues in the diagnosis and management of achalasia as discussed in a symposium that took place in Kagoshima, Japan, in September 2010 under the auspices of the International Society for Diseases of the Esophagus.

  11. Acute Necrotizing Esophagitis Followed by Duodenal Necrosis.

    2011-12-01

    Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

    The incidence of esophageal cancer is rapidly increasing especially in developing countries. The major risk factors include unhealthy lifestyle practices such as alcohol consumption, smoking, and chewing tobacco to name a few. Diagnosis at an advanced stage and poor prognosis make esophageal cancer one of the most lethal diseases. These factors have urged further research in understanding the pathophysiology of the disease. Animal models not only aid in understanding the molecular pathogenesis of esophageal cancer but also help in developing therapeutic interventions for the disease. This review throws light on the various recent laboratory animal models for esophageal cancer. PMID:27956773

    Noxious stimuli in the esophagus activate nociceptive receptors on esophageal mucosa, such as transient receptor potential, acid-sensing ion channel and the P2X family, a family of ligand-gated ion channels responsive to ATP, and this generates signals that are transmitted to the central nervous system via either spinal nerves or vagal nerves, resulting in esophageal sensation. Among the noxious stimuli, gastric acid and other gastric contents are clinically most important, causing typical reflux symptoms such as heartburn and regurgitation. A conventional acid penetration theory has been used to explain the mechanism of heartburn, but much recent evidence does not support this theory. Therefore, it may be necessary to approach the causes of heartburn symptoms from a new conceptual framework. Hypersensitivity of the esophagus, like that of other visceral organs, includes peripheral, central and probably psychosocial factor-mediated hypersensitivity, and is known to play crucial roles in the pathoegenesis of nonerosive reflux disease, functional heartburn and non-cardiac chest pain. There also are esophagitis patients who do not perceive typical symptoms. This condition is known as silent gastroesophageal reflux disease. Although the pathogenesis of silent gastroesophageal reflux disease is still not known, hyposensitivity to reflux of acid may possibly explain the condition.

    2013-07-01

    Eosinophilic esophagitis (EoE) is an emerging disease defined by esophageal dysfunction, by typical endoscopic findings and by abnormal eosinophilic inflammation within the esophagus. Eosinophilic accumulation in the esophagus occurs as a result of esophageal overexpression of pro-inflammatory mediators, including T cells and mast cells, cytokines such as interleukin (IL)-13, IL-5 and IL-15, as well as chemoattractants (eotaxin and transforming growth factor-β1, fibroblast growth factor and the newly characterized gene--thymic stromal lymphopoietin, which is a key regulator of allergic sensitization initiation). The role of allergy, particularly food allergy in EoE is indisputable, as elimination diet is a proven commonly used treatment for the disease. However, unlike classical immediate IgE-mediated reaction to allergen, EoE is associated with an altered immune response, characterized by a combination of IgE-mediated and non-IgE-mediated mechanisms. In this review, we aim to discuss the many typical aspects of EoE as opposed to other entities involving the esophagus, with focusing on the aberrant immune-mediated key players contributing to the pathogenesis of this unique disease.

    2012-10-07

    To test the hypothesis that disturbed flow can impede the transport of nitric oxide (NO) in the artery and hence induce atherogenesis, we used a lumen-wall model of an idealized arterial stenosis with NO produced at the blood vessel-wall interface to study the transport of NO in the stenosis. Blood flows in the lumen and through the arterial wall were simulated by Navier-Stokes equations and Darcy's Law, respectively. Meanwhile, the transport of NO in the lumen and the transport of NO within the arterial wall were modelled by advection-diffusion reaction equations. Coupling of fluid dynamics at the endothelium was achieved by the Kedem-Katchalsky equations. The results showed that both the hydraulic conductivity of the endothelium and the non-Newtonian viscous behaviour of blood had little effect on the distribution of NO. However, the blood flow rate, stenosis severity, red blood cells (RBCs), RBC-free layer and NO production rate at the blood vessel-wall interface could significantly affect the transport of NO. The theoretical study revealed that the transport of NO was significantly hindered in the disturbed flow region distal to the stenosis. The reduced NO concentration in the disturbed flow region might play an important role in the localized genesis and development of atherosclerosis.

  18. Pradaxa-induced esophageal ulcer.

    Pradaxa (dabigatran) is a direct thrombin inhibitor approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. We describe a case of esophageal ulceration associated with Pradaxa administration in a 75-year-old man. The patient reported difficulty swallowing and a burning sensation after taking his first dose of Pradaxa. An esophagogastroduodenoscopy (EGD) revealed linear ulcerations in the mid-esophagus. Pradaxa was held beginning the day before the EGD. The patient reported that his pain and difficulty swallowing resolved on stopping Pradaxa. Pradaxa is formulated with a tartaric acid excipient to reduce variability in absorption. We hypothesise that the capsule lodged in the patient's esophagus and the tartaric acid may have caused local damage resulting in an esophageal ulcer. It is important to educate patients on proper administration of Pradaxa, to decrease the risk of this rare, but potentially serious adverse event.

    Internal carotid stenosis constitutes a significant clinical challenge, since it is the cause of 20–25% of ischemic brain strokes. The management of the internal carotid stenosis for many years has been raising controversies amongst neurologists, vascular surgeons and interventional radiologists mainly due to the introduction of endovascular stenting as an alternative to surgical treatment. Its application, however, requires knowledge of specific selection criteria for this kind of treatment as well as of the methods of monitoring patients after stent implantation into the internal carotid artery. Duplex Doppler ultrasound examination is currently a basis for the diagnosis of the arterial stenosis of precranial segments of the carotid arteries. It allows a reliable assessment of not only the course and morphology of the walls, but also of the hemodynamics of blood flow. Interventional treatment is applicable in patients with internal carotid stenosis of ≥70%, which is accompanied by an increase of the systolic flow velocity above 200 cm/s and the end-diastolic velocity above 50–60 cm/s in the stenotic lumen. In most cases, such a diagnosis in duplex Doppler ultrasound examination does not require any confirmation by additional diagnostic methods and if neurological symptoms are also present, it constitutes a single indication for interventional treatment. When deciding about choice of surgical or endovascular method of treatment, the following factors are of crucial importance: morphology of atherosclerotic plaque, its size, echogenicity, homogeneity of its structure, its surface and outlines. By means of ultrasound examinations, patients can be monitored after endovascular stent implantation. They enable evaluation of the degree of stent patency and allow for an early detection of symptoms indicating stenosis recurrence or presence of in-stent thrombosis.

    Percutaneous balloon valvuloplasty is considered the standard of care for treatment of valvular pulmonic stenosis, a common congenital defect in dogs. Supravalvular pulmonic stenosis is a rare form of pulmonic stenosis in dogs and standard treatment has not been established. Although, there have been reports of successful treatment of supravalvular pulmonic stenosis with surgical and stenting techniques, there have been no reports of balloon dilation to treat dogs with this condition. Here, a case of supravalvular pulmonic stenosis diagnosed echocardiographically and angiographically in which a significant reduction in pressure gradient was achieved with balloon dilation alone is presented.

  2. Distal esophageal spasm: an update.

    Achem, Sami R; Gerson, Lauren B

    2013-09-01

    Distal esophageal spasm (DES) is an esophageal motility disorder that presents clinically with chest pain and/or dysphagia and is defined manometrically as simultaneous contractions in the distal (smooth muscle) esophagus in ≥20% of wet swallows (and amplitude contraction of ≥30 mmHg) alternating with normal peristalsis. With the introduction of high resolution esophageal pressure topography (EPT) in 2000, the definition of DES was modified. The Chicago classification proposed that the defining criteria for DES using EPT should be the presence of at least two premature contractions (distal latency<4.5 s) in a context of normal EGJ relaxation. The etiology of DES remains insufficiently understood, but evidence links nitric oxide (NO) deficiency as a culprit resulting in a disordered neural inhibition. GERD frequently coexists in DES, and its role in the pathogenesis of symptoms needs further evaluation. There is some evidence from small series that DES can progress to achalasia. Treatment remains challenging due in part to lack of randomized placebo-controlled trials. Current treatment agents include nitrates (both short and long acting), calcium-channel blockers, anticholinergic agents, 5-phosphodiesterase inhibitors, visceral analgesics (tricyclic agents or SSRI), and esophageal dilation. Acid suppression therapy is frequently used, but clinical outcome trials to support this approach are not available. Injection of botulinum toxin in the distal esophagus may be effective, but further data regarding the development of post-injection gastroesophageal reflux need to be assessed. Heller myotomy combined with fundoplication remains an alternative for the rare refractory patient. Preliminary studies suggest that the newly developed endoscopic technique of per oral endoscopic myotomy (POEM) may also be an alternative treatment modality.

  3. Optimal lymphadenectomy for esophageal adenocarcinoma.

    PubMed

    Oezcelik, A

    2013-08-01

    Recently published data have shown that an extended lymphadenectomy during the en bloc esophagectomy leads to a significant increased long-term survival for esophageal adenocarcinoma. On the other hand some studies indicate that the increased survival is based on stage migration and that the surgical complication rate is increased after extended lymphadenectomy. The aim of this review was to give an overview about all aspects of an extended lymphadenectomy in patients with esophageal adenocarcinoma. The review of the literature shows clearly that the number of involved lymph nodes is an independent prognostic factor in patients with esophageal adenocarcinoma. Furthermore, an extended lymphadenectomy leads to an increased long-term survival. Some studies describe that 23 lymph nodes should be removed to predict survival; other studies 18 lymph nodes or 15 lymph nodes. Opponents indicate that the survival benefit is based on stage migration. The studies with a large study population have performed a Cox regression analyzes and identified the number of lymph nodes removed as an independent factor for improved survival, which means it is significant independently from other parameters. Under these circumstances is stage migration not an option to explain the survival benefit. An important difficulty is, that there is no standardized definition of an extended lymphadenectomy, which means the localization and number of removed lymph nodes differ depending from the performing centre. The controversies regarding the survival benefit of the lymphadenectomy is based on the lack of standardisation of the lymphadenectomy. The main goal of further studies should be to generate a clear definition of an extended lymphadenectomy in patients with esophageal adenocarcinoma.

    2013-01-01

    Eosinophilic esophagitis (EoE) is a clinicopathologic, chronic esophageal inflammatory disease resistant to acid suppressive therapy and is associated with variable symptoms indicative of upper gastrointestinal dysfunction. Per current guidelines established by The International Group of Eosinophil Researchers (TIGERS), the diagnosis is made in symptomatic patients after a biopsy that confirms a peak eosinophil level of ≥15 eosinophils/high-powered field (HPF). The esophagus is distinguished by pronounced tissue eosinophilia in which dietary antigens are key inciting factors for disease pathogenesis; EoE being reversed by elimination of triggering food allergens suggests that the disease is mediated in part by allergic sensitization to foods. Moreover, experimental EoE in mice can be induced not only via food exposure but also via aeroallergen exposure. Consistent with an allergic etiology rather than an acid-induced esophagitis, swallowed glucocorticoids are effective for the treatment of EoE. Evaluation by an allergist is a recommended part of the diagnostic workup, especially for management of allergic comorbidities. Clinical practice for the evaluation of patients with EoE mainly relies on prick skin tests due to the ease and validation of these tests in the context of immediate hypersensitivity. However, both atopy patch testing and serum IgE testing have been used in EoE. Herein, we reviewed the basic clinical features of EoE with a focus on the approach to diagnosing causative food allergens and to dietary therapy.

    This study assessed esophageal motility in patients with esophageal varices by radionuclide transit studies. Data were acquired in list mode after an oral dose of 0.5 mCi Tc-99m sulfur colloid in 10 ml of water in the supine position above a low-energy all-purpose collimator of a gamma camera. The condensed image (CI) superimposed with a centroid curve was also produced in each case. Twenty-five normal subjects (N) and 32 patients (pts) with esophageal varices by endoscopy (large varices in Grades IV and V in 8 and small varices in Grade III or less in 24) were studied. TMTT, RTT, RF, and RI were all significantly increased in pts as compared to N. Especially, the transit time for the middle third (6.7 +- 2.6 sec vs 3.5 +- 0.9 sec in N, rho < 0.005) had the optimal sensitivy and specificity of 88% each at the cutoff value of 4.2 sec as determined by ROC analysis. In summary, radionuclide transit disorders occur in the majority of pts with esopageal varices. The middle RTT and CI are both optimal in sensitivity and specificity for detecting the abnormalities.

  6. A Systematic Review of the Risk of Perforation During Esophageal Dilation for Patients with Eosinophilic Esophagitis

    2011-01-01

    Background Eosinophilic esophagitis (EoE) is associated with tissue remodeling that can result in esophageal mucosal fragility, and esophageal dilation for patients with EoE is known to cause painful mucosal lacerations. Clinicians have been admonished that patients with EoE may be exceptionally predisposed to perforation with esophageal dilation, a notion supported primarily by case reports. We have conducted a systematic review of literature on esophageal dilation in EoE in an attempt to better define the risk of perforation. Methods We searched PubMed and abstracts presented at the annual scientific meetings of the American Gastroenterological Association and the American College of Gastroenterology to identify reports on esophageal dilation in EoE. We analyzed reports meeting the following criteria: (1) the diagnosis was established from esophageal biopsy specimens revealing ≥15 eosinophils/hpf, (2) esophageal dilation was described, (3) esophageal perforations described were the result of esophageal dilation. Results We identified 18 reports for inclusion in our systematic review. The studies comprised 468 patients who underwent a total of 671 endoscopic dilations. Esophageal mucosal tears were described in most cases, but there was only one perforation among the 671 dilations (0.1%). Conclusions Our systematic review does not reveal an inordinate frequency of esophageal perforation from dilation in patients with EoE, and it is not clear that dilation is any more hazardous for patients with EoE than for patients with other causes of esophageal stricture. Although esophageal dilation must be performed with caution in all patients, the risk of perforation in EoE appears to have been exaggerated. PMID:20238250

    Magnetic Particle Imaging (MPI) is able to provide high temporal and good spatial resolution, high signal-to-noise ratio and sensitivity. Furthermore, it is a truly quantitative method as its signal strength is proportional to the concentration of its tracer, superparamagnetic iron oxide nanoparticles (SPIOs). Because of that, MPI is proposed to be a promising future method for cardiovascular imaging. Here, an interesting application may be the quantification of vascular pathologies like stenosis by utilizing the proportionality of the SPIO concentration and the MPI signal strength. In this study, the feasibility of MPI based stenosis quantification is evaluated based on this application scenario. Nine different stenosis phantoms with a normal diameter of 10 mm each and different stenoses of 1–9 mm and ten reference phantoms with a straight diameter of 1–10 mm were filled with a 1% Resovist dilution and measured in a preclinical MPI-demonstrator. The MPI signal intensities of the reference phantoms were compared to each other and the change of signal intensity within each stenosis phantom was used to calculate the degree of stenosis. These values were then compared to the known diameters of each phantom. As a second measurement, the 5 mm stenosis phantom was used for a serial dilution measurement down to a Resovist dilution of 1:3200 (0.031%), which is lower than a first pass blood concentration of a Resovist bolus in the peripheral arteries of an average adult human of at least about 1:1000. The correlation of the stenosis values based on MPI signal intensity measurements and based on the known diameters showed a very good agreement, proving the high precision of quantitative MPI in this regard.

Nine different stenosis phantoms with a normal diameter of 10 mm each and different stenoses of 1-9 mm and ten reference phantoms with a straight diameter of 1-10 mm were filled with a 1% Resovist dilution and measured in a preclinical MPI-demonstrator. The MPI signal intensities of the reference phantoms were compared to each other and the change of signal intensity within each stenosis phantom was used to calculate the degree of stenosis. These values were then compared to the known diameters of each phantom. As a second measurement, the 5 mm stenosis phantom was used for a serial dilution measurement down to a Resovist dilution of 1:3200 (0.031%), which is lower than a first pass blood concentration of a Resovist bolus in the peripheral arteries of an average adult human of at least about 1:1000. The correlation of the stenosis values based on MPI signal intensity measurements and based on the known diameters showed a very good agreement, proving the high precision of quantitative MPI in this regard.

  17. Esophageal mucosal damage may promote dysmotility and worsen esophageal acid exposure.

    This study determines the relationship among esophageal dysmotility, esophageal acid exposure, and esophageal mucosal injury in patients with gastroesophageal reflux disease (GERD). A total of 827 patients with GERD (confirmed by ambulatory pH monitoring) were divided into three groups based on the degree of mucosal injury: group A, no esophagitis, 493 patients; group B, esophagitis grades I to III, 273 patients; and group C, Barrett's esophagus, 61 patients. As mucosal damage progressed from no esophagitis to Barrett's esophagus, there was a significant decrease in lower esophageal sphincter pressure and amplitude of peristalsis in the distal esophagus, with a subsequent increase in the number of reflux episodes in 24 hours, the number of reflux episodes longer than 5 minutes, and the reflux score. These data suggest that in patients with GERD, worsening of esophageal mucosal injury may determine progressive deterioration of esophageal motor function with impairment of acid clearance and increase of esophageal acid exposure. These findings suggest that Barrett's esophagus is an end-stage form of gastroesophageal reflux, and that if surgical therapy is performed early in the course of the disease, this cascade of events might be blocked.

  18. The Esophageal Propulsive Force: Esophageal Response to Acute Obstruction*

    PubMed Central

    Winship, Daniel H.; Zboralske, F. Frank

    1967-01-01

    The response of the normal human esophagus to an obstructing intraluminal bolus was investigated and compared to the response evoked by transient intraluminal distention. A balloon, immobilized within the esophagus by external attachment to a force transducer, was inflated with from 3 to 25 ml of air for from 3 to 210 sec. Pressure phenomena occurring in the esophagus were simultaneously recorded from the body of the esophagus above and below the balloon. Transient distention (5 sec or less) with small volumes (5 ml or less) often evoked a secondary peristaltic wave in the esophagus distal to the balloon, but infrequently resulted in the registration of any force exerted upon the balloon to drive it downward. Conversely, distentions of longer duration and with greater volume elicited an esophageal propulsive force exerted upon the balloon oriented to propel it aborally, and much less often evoked a propagated wave of secondary peristalsis. The propulsive force, obviously resulting from esophageal muscular contraction, occurred promptly, and once initiated, was sustained until deflation of the balloon. It varied widely in magnitude, from 4 to 200 g, and was associated with no motor phenomena recorded from the body of the esophagus proximal or distal to the balloon which could account for its presence, onset, magnitude, or duration. The force was inhibited by deglutition, but arrival of the primary peristaltic wave at the bolus resulted in augmentation of the force. When the obstructing balloon was freed from its attachment, the persistent, stationary force was converted to a propagated one that propelled the balloon before it. It the balloon was arrested before entering the stomach, the moving contraction was also arrested and the persistent propulsive force acting upon the balloon was maintained. The velocity of the moving contraction wave was determined in great part by the resistance offered by the bolus. Unrestrained, the balloon was propelled aborally at 4-8 cm

    The incidence of aortic stenosis increases with age, affecting up to 10% of the population by the eighth decade. Once symptoms develop, aortic stenosis is rapidly fatal. Proper management requires an understanding of the physiology and criteria used to define disease severity. There is no effective pharmacologic treatment. Surgical aortic valve replacement has been the gold standard treatment for decades. However, over the last 10 years transcatheter aortic valve replacement has emerged as an attractive, less-invasive option for appropriately selected patients. Refinements in valve design and delivery systems have led to widespread use of this breakthrough technology in selected patients. We review the pathophysiology, criteria for valve replacement, and the results of the trials comparing transcatheter aortic valve replacement with surgical aortic valve replacement.

    Two children are reported with hydrocephalus and aqueduct stenosis who presented with back and limb pains. Neither had the classic symptoms of headache and vomiting. The children had enlarged heads and later developed ataxic gait and papilloedema. The cause of the pains is uncertain but similar symptoms have been reported in subjects with benign intracranial hypertension and may relate to spinal nerve root pouch distension. Operative ventricular drainage resulted in rapid improvement of all symptoms in both children.

    Background Degenerative lumbar stenosis associated with spondylolisthesis is common in elderly patients. The most common symptoms are those of neurogenic claudication with leg pain. Surgery is indicated for those who fail conservative management. The generally accepted recommendation is to perform a laminectomy and a fusion at the involved level. Methods We reviewed our results for minimally invasive single-level decompression without fusion performed by the senior author in patients with symptomatic lumbar stenosis with spondylolisthesis with no dynamic instability from 2008 to 2011 at a single institution. Outcomes were measured using the visual analog scale (VAS), Prolo Economic Functional Rating Scale, and revised Oswestry Disability Index (ODI) at initial presentation and at 3-month, 6-month, and 1-year follow-up time points. Results Records for 28 patients (19 males, 9 females) were reviewed. The success rate, defined as improvement in pain and functional outcome without the need for surgical fusion, was 86%. VAS scores decreased by 6.3 points, Prolo scores increased by 3.5 points, and the ODI decreased by 31% at 1 year. All changes were statistically significant. Conclusion Minimally invasive decompression alone can be a reasonable alternative to decompression and fusion for patients with spondylolisthetic lumbar stenosis and neurogenic claudication with leg pain. Decompression without fusion should be considered for older patients and for patients who are not ideal fusion candidates. PMID:24688331

    Aortic valve stenosis, which causes considerable constriction of the flow passage, is one of the most frequent cardiovascular diseases and is the most common cause of the valvular replacements which take place for around 100,000 per year in North America. Furthermore, it is considered as the most frequent cardiac disease after arterial hypertension and coronary artery disease. The objective of this study is to develop an analytical model considering the coupling effect between fluid flow and elastic deformation with reasonable boundary conditions to describe the effect of AS on the left ventricle and the aorta. The pulsatile and Newtonian blood flow through aortic stenosis with vascular wall deformability is analyzed and its effects are discussed in terms of flow parameters such as velocity, resistance to flow, shear stress distribution and pressure loss. Meanwhile we developed analytical expressions to improve the comprehension of the transvalvular hemodynamics and the aortic stenosis hemodynamics which is of great interest because of one main reason. To medical scientists, an accurate knowledge of the mechanical properties of whole blood flow in the aorta can suggest a new diagnostic tool.

  3. Activity assessment of eosinophilic esophagitis.

    2014-01-01

    The activity of eosinophilic esophagitis (EoE) can be assessed with patient-reported outcomes and biologic measures. Patient-reported outcomes include symptoms and quality of life, whereas biologic measures refer to endoscopic, histologic, and biochemical activity (e.g. blood biomarkers). So far, a validated tool to assess EoE activity in the above-mentioned dimensions is lacking. Given the lack of a standardized way to assess EoE activity in the various dimensions, the results of different clinical trials may be difficult to compare. For symptom assessment in adult patients, the symptom 'dysphagia' should be evaluated according to different standardized food consistencies. Furthermore, symptom assessment should take into account the following items: avoidance of specific food categories, food modification, and time to eat a regular meal. A distinct symptom recall period (e.g. 2 weeks) has to be defined for symptom assessment. Performing an 'esophageal stress test' with ingestion of a standardized meal to measure symptom severity bears the potential risk of acute food bolus impaction and should therefore be avoided. The description of endoscopic findings in EoE has meanwhile been standardized. Histologic evaluation of EoE activity should report either the size of the high-power field used or count the eosinophils per mm(2). There is a current lack of blood biomarkers demonstrating a good correlation with histologic activity in esophageal biopsies. The development and validation of an adult and pediatric EoE activity index is urgently needed not only for clinical trials and observational studies, but also for daily practice.

    The rupture of gastric varices results in variceal hemorrhage, which is one the most lethal complications of cirrhosis. Endoscopic therapies for varices aim to reduce variceal wall tension by obliteration of the varix. The two principal methods available for esophageal varices are endoscopic sclerotherapy (EST) and band ligation (EBL). The advantages of EST are that it is cheap and easy to use, and the injection catheter fits through the working channel of a diagnostic gastroscope. Endoscopic variceal ligation obliterates varices by causing mechanical strangulation with rubber bands. The following review aims to describe the utility of EBL and EST in different situations, such as acute bleeding, primary and secondary prophylaxis.

    Four studies reported an increasing incidence of pyloric stenosis during the late 1970s from geographically diverse areas of the United Kingdom. It was suggested that the increased incidence might be related to changes in infant feeding practices. We used data from the Metropolitan Atlanta Congenital Defects Program, a population based birth defects registry, to examine the secular trends and descriptive epidemiology of pyloric stenosis in a North American city. For the period 1968 to 1982, the incidence of pyloric stenosis was 1.33 per 1000 live births; there was no evidence of an increasing trend for either race or sex specific rates of pyloric stenosis. The descriptive epidemiology of the pyloric stenosis cases showed higher rates for males, whites, and infants of higher birth weight. We found no increasing trend in pyloric stenosis incidence in Atlanta, despite well documented changes in US infant feeding practices (an increased prevalence of breast feeding) during the 1970s.

    Noncardiac chest pain (NCCP) is an often-encountered clinical problem. Although many patients suffer from persistent or recurrent chest pain, treatment remains a challenge owing to its various possible etiologies. Gastroesophageal reflux disease (GERD) is the most common cause of NCCP. In GERD-related NCCP, proton pump inhibitor treatment appears to be effective. However, the pathophysiology remains to be fully elucidated in NCCP patients without GERD. Treatment for non-GERD-related NCCP has been aimed at esophageal motility disorders and visceral hypersensitivity. As there is growing evidence that esophageal visceral hypersensitivity plays a role in NCCP, pain modulators have become the mainstay of therapy in patients with non-GERD-related NCCP. However, there is an unmet need for the treatment of esophageal hypersensitivity in NCCP due to modest evidence for the benefit of pain modulators, including antidepressants, in non-GERD-related NCCP. Recent studies have demonstrated that esophageal mast cell infiltration and impaired mucosal integrity are related to visceral hypersensitivity in patients with NCCP. Thus, esophageal mast cell stabilization and restoration of esophageal mucosal integrity could be considered potential therapeutic targets in selected NCCP patients with hypersensitivity. However, further observations are necessary to shed light on esophageal hypersensitivity in NCCP.

    Esophageal involvement is an extremely rare complication of tuberculosis even in countries with high prevalence of infection. We report the case of a 57 year-old hiv-seronegative patient with simultaneous diagnoses of oral blastomycosis and laryngeal papillomatosis. Both were confirmed by anatomopathological analysis. The esophageal biopsy revealed granulomatous esophagitis with necrosis and ziehl-neelsen stain showed acid-fast alcohol resistant bacilli suggestive of tuberculosis. The patient's history included pulmonary tuberculosis twice and previous abandonment of therapy. Thus, it was necessary to use oral itraconazole combined with second-line anti-tuberculosis drugs administered through a gastrostomy tube. The clinical development was favorable.

    The presence of a coronary stenosis results primarily in subendocardial ischemia. Apart from the decrease in coronary perfusion pressure, a stenosis also decreases coronary flow pulsations. Applying a coronary perfusion system, we compared the autoregulatory response of subendocardial (n = 10) and subepicardial (n = 12) arterioles (<120 microm) after stepwise decreases in coronary arterial pressure from 100 to 70, 50, and 30 mmHg in vivo in dogs (n = 9). Pressure steps were performed with and without stenosis on the perfusion line. Maximal arteriolar diameter during the cardiac cycle was determined and normalized to its value at 100 mmHg. The initial decrease in diameter during reductions in pressure was significantly larger at the subendocardium. Diameters of subendocardial and subepicardial arterioles were similar 10--15 s after the decrease in pressure without stenosis. However, stenosis decreased the dilatory response of the subendocardial arterioles significantly. This decreased dilatory response was also evidenced by a lower coronary inflow at similar average pressure in the presence of a stenosis. Inhibition of nitric oxide production with N(G)-monomethyl-L-arginine abrogated the effect of the stenosis on flow. We conclude that the decrease in pressure caused by a stenosis in vivo results in a larger decrease in diameter of the subendocardial arterioles than in the subepicardial arterioles, and furthermore stenosis selectively decreases the dilatory response of subendocardial arterioles. These two findings expand our understanding of subendocardial vulnerability to ischemia.

    Subglottic stenosis is one of the most common causes of upper airway obstruction in children. Even though it may have a congenital origin, most of them are acquired stenosis. This condition should be suspected in any child with a history of intubation, instrumentation or trauma of the airway that is having difficulty breathing. The diagnosis is suspected by clinical, history and cervical radiograph, and is confirmed by endoscopic examination. Among others factors the treatment depends on the stenosis degree. We describe our experience with 6 patients with post-intubation subglottic stenosis treated surgically with expansion technique.

    Thoracic spinal stenosis is a relatively common disorder causing paraplegia in the population of China. Until nowadays, the clinical management of thoracic spinal stenosis is still demanding and challenging with lots of questions remaining to be answered. A clinical guideline for the treatment of symptomatic thoracic spinal stenosis has been created by reaching the consensus of Chinese specialists using the best available evidence as a tool to aid practitioners involved with the care of this disease. In this guideline, many fundamental questions about thoracic spinal stenosis which were controversial have been explained clearly, including the definition of thoracic spinal stenosis, the standard procedure for diagnosing symptomatic thoracic spinal stenosis, indications for surgery, and so on. According to the consensus on the definition of thoracic spinal stenosis, the soft herniation of thoracic discs has been excluded from the pathological factors causing thoracic spinal stenosis. The procedure for diagnosing thoracic spinal stenosis has been quite mature, while the principles for selecting operative procedures remain to be improved. This guideline will be updated on a timely schedule and adhering to its recommendations should not be mandatory because it does not have the force of law.

    Communicating bronchopulmonary foregut malformation (CBPFM) and congenital tracheal stenosis (CTS) are difficult developmental disorders especially when they are presented simultaneously in a patient. The authors report a case of a newborn boy born at 37 weeks of gestation weighing 2356 g with CBPFM (right esophageal lung) and long segment CTS. Staged surgical repair (by-force endotracheal intubation for securing the airway followed by bronchotracheal anastomosis for CBPFM, tracheostomy with handmade, length-adjustable tracheostomy tube, and slide tracheoplasty) was performed. He has been healthy without tracheostomy for 25 months after slide tracheoplasty. This is the first report of a successful tracheobronchial reconstruction for a patient with a long segment CTS and CBPFM preserving the affected lung function.

    1998-09-01

    Animal studies were done using an in vivo dog model to examine the possible mechanism for the esophageal adverse events reported with alendronate sodium tablets. These studies showed that under low pH conditions alendronate sodium can cause esophageal irritation. No esophageal irritation occurred at pH 3.5 or higher where the drug exists primarily as the sodium salt. The animal studies also showed that alendronate sodium can exacerbate preexisting esophageal damage. Exposure of the esophageal mucosa for a prolonged period to alendronate sodium tablet can also cause mild esophageal irritation. These findings suggest that the esophageal irritation in patients taking Fosamax can be from prolonged contact with the tablet, reflux of acidic gastric contents with alendronate sodium, and exacerbation of preexisting esophageal damage. The findings also suggest that other bisphosphonates can cause esophageal injury under similar conditions.

    AIM To understand the molecular mechanism of esophageal cancer development and provide molecular markers for screening high-risk populations and early diagnosis. METHODS Two-dimensional electrophoresis combined with mass spectrometry were adopted to screen differentially expressed proteins in nine cases of fetal esophageal epithelium, eight cases of esophageal cancer, and eight cases of tumor-adjacent normal esophageal epithelium collected from fetuses of different gestational age, or esophageal cancer patients from a high-risk area of esophageal cancer in China. Immunohistochemistry (avidin-biotin-horseradish peroxidase complex method) was used to detect the expression of peroxiredoxin (PRX)6 in 91 cases of esophageal cancer, tumor-adjacent normal esophageal tissue, basal cell hyperplasia, dysplasia, and carcinoma in situ, as well as 65 cases of esophageal epithelium from fetuses at a gestational age of 3-9 mo. RESULTS After peptide mass fingerprint analysis and search of protein databases, 21 differential proteins were identified; some of which represent a protein isoform. Varying degrees of expression of PRX6 protein, which was localized mainly in the cytoplasm, were detected in adult and fetal normal esophageal tissues, precancerous lesions, and esophageal cancer. With the progression of esophageal lesions, PRX6 protein expression showed a declining trend (P < 0.05). In fetal epithelium from fetuses at gestational age 3-6 mo, PRX6 protein expression showed a declining trend with age (P < 0.05). PRX6 protein expression was significantly higher in well-differentiated esophageal cancer tissues than in poorly differentiated esophageal cancer tissues (P < 0.05). CONCLUSION Development and progression of esophageal cancer result from interactions of genetic changes (accumulation or superposition). PRX6 protein is associated with fetal esophageal development and cancer differentiation. PMID:28293090

    Clinical symptoms and diagnostic findings in patients with mitral stenosis are usually determined by the extent of the stenosis. Compared to a normal mitral valve area (MVA) of > 4 cm2, MVA in patients with severe mitral stenosis is usually reduced to < 1.5 cm2. In older patients symptoms are frequently influenced by concomitant diseases (e.g. atrial fibrillation, arterial hypertension or lung disease). An important diagnostic element besides anamnesis, auscultation, ECG and chest X-ray is echocardiography, which is required in order to measure non-invasively and reliably the mitral valve gradient (MVG), the MVA and morphologic changes to the valves, as well as concomitant valvular disease, ventricular functions and, where appropriate, left-atrial thrombi. In addition to the surgical treatment of patients with severe mitral stenosis, which has been an established procedure for 50 years, percutaneous balloon mitral valvuloplasty (MVP) has recently established itself as an alternative option. At the current time, the Inoue technique seems to display the most advantages. Following transseptal puncture, the Inoue balloon is guided transvenously into the left atrium and then into the left ventricle using a special support wire. The balloon is short and soft. Its special unfolding character enables it to be placed securely in the mitral valve without any risk of ventricular perforation (Figure 1). As with surgical commissurotomy, balloon valvuloplasty leads to a separation of fused commissures. This results in a significant reduction of MVG, accompanied by an increase in the MVA (Figure 2). The results and success of MVP are influenced by the morphology of the valves and the changes to the subvalvular apparatus. In randomized studies, the results of surgical commissurotomy were comparable with those of balloon mitral valvulotomy. In our hospital, an increase in MVA from 1.0 to 1.8 cm2 could be achieved in 899 patients (mean age 56 +/- 3 years). In younger patients with

    Systemic sclerosis is a rare connective tissue disease, distinctive features of which are fibrosis and microangiopathy. The esophagus is one of the most commonly involved internal organs. Most patients experience dysphagia, difficulties in swallowing and gastro-esophageal reflux. However, in up to one third of cases, the initial onset of esophageal disease may be clinically silent. There are several diagnostic modalities available for assessing both morphological and functional abnormalities of the esophagus. If structural abnormalities are suspected, endoscopy is the method of choice. Functional evaluation is best achieved with manometry. Both endoscopy and manometry are invasive techniques, with low patient acceptance. Barium-contrast study is well tolerated, but qualitative assessment of functional abnormalities is imprecise. Esophageal scintigraphy is an easy, non-invasive, sensitive and specific diagnostic modality. It can detect esophageal dysfunction even in asymptomatic patients. In patients already diagnosed with systemic sclerosis, scintigraphy is useful in evaluating severity and progression of the disease. PMID:27994270

    The management of esophageal and gastric cancer is complex and involves multiple specialists in an effort to optimize patient outcomes. Utilizing a multidisciplinary team approach starting from the initial staging evaluation ensures that all members are in agreement with the plan of care. Treatment selection for esophageal and gastric cancer often involves a combination of chemotherapy, radiation, surgery, and palliative interventions (endoscopic and surgical), and direct communication between specialists in these fields is needed to ensure appropriate clinical decision making. At the University of Colorado, the Esophageal and Gastric Multidisciplinary Clinic was created to bring together all experts involved in treating these diseases at a weekly conference in order to provide patients with coordinated, individualized, and patient-centered care. This review details the essential elements and benefits of building a multidisciplinary program focused on treating esophageal and gastric cancer patients. PMID:27217796

    Eosinophilic esophagitis (EoE) is a chronic and progressive immune-mediated condition defined by symptoms of esophageal dysfunction and dense eosinophilic infiltration of the esophageal mucosa. Therapies consist of anti-eosinophilic medications and specialized diets aimed to decrease the progression of EoE and alleviate its symptoms, namely, dysphagia and food impaction. Assessing response to therapy remains challenging, as treatment end points are not well defined and currently consist of clinical, histologic, and endoscopic features. Newer validated measures may help standardize treatment end points. Emerging data support the use of maintenance therapy, which may reduce disease progression. Optimal dosages, delivery techniques, and duration of treatment need to be determined. When features of fibrostenosis develop, esophageal dilation is a safe and effective adjunctive strategy for improving symptoms. In EoE cases refractory to conventional treatments, newer therapies targeting inflammatory mediators and cytokines are on the horizon. PMID:27695356

    Squamous papilloma of the esophagus is a rare benign lesion of the esophagus. Radiofrequency ablation is an established endoscopic technique for the eradication of Barrett esophagus. No cases of endoscopic ablation of esophageal papilloma by radiofrequency ablation (RFA) have been reported. We report a case of esophageal papilloma successfully treated with a single session of radiofrequency ablation. Endoscopic ablation of the lesion was achieved by radiofrequency using a new catheter inserted through the working channel of endoscope. The esophageal ablated tissue was removed by a specifically designed cup. Complete ablation was confirmed at 3 mo by endoscopy with biopsies. This case supports feasibility and safety of as a new potential indication for BarrxTM RFA in patients with esophageal papilloma. PMID:25789102

    Autoimmune blistering skin diseases, including pemphigus vulgaris, rarely involve the esophagus. We report a case of exfoliative esophagitis with pemphigus vulgaris. A sloughing esophageal cast observed by endoscopy was dissected esophageal squamous epithelium in all layers. Our case is the fifth case of pemphigus vulgaris associated with esophageal cast formation recorded in the medical literature. Prednisolone was administered, and both the pemphigus vulgaris and exfoliative esophagitis improved. Upon findings of exfoliative esophagitis by endoscopic examination, we should consider the coexistence of blistering skin diseases, including pemphigus vulgaris.

    After surgical correction of esophageal atresia with or without tracheoesophageal fistula, esophageal body motility dysfunction has been reported in nearly all patients. Using high-resolution esophageal manometry before surgical repair in 2 children with isolated tracheoesophageal fistula, we sought to determine whether dysmotility was present before any surgical insult to test the hypothesis that dysmotility associated with esophageal atresia with or without tracheoesophageal fistula is related to intrinsic primary factors linked to abnormal development of the esophagus. Both had an abnormal esophageal motility: one exhibited hypomotility with distal contraction, whereas the other showed a complete aperistalsis pattern. This suggests that esophageal dysmotility is congenital in nature rather than secondary to surgery.

    Endoscopic ultrasonography (EUS) has been widely used for evaluating the nature of diseases of various organs. The possibility of applying EUS for esophageal motility diseases has not been well discussed despite its versatility. At present, peroral endoscopic myotomy (POEM) for esophageal achalasia and related diseases has brought new attention to esophageal diseases because POEM provides a more direct approach to the inner structures of the esophageal wall. In the present study, we discuss the clinical utility of EUS in evaluating and treating esophageal motility diseases such as esophageal achalasia and related diseases.

    The purpose of this review is to explore the pathophysiology, epidemiology, and interventional treatment of central vein stenosis (CVS) that may result from central vein catheter (CVC) placement. The precise mechanism of CVC-associated CVS remains largely undefined, though anatomic considerations appear to play a prominent pathologic role. The impact of CVC-associated CVS on arteriovenous fistula outcomes is reviewed. The percutaneous treatment of CVS, observation, angioplasty, or angioplasty with stent placement is reviewed, along with potential surgical treatment options. As the treatment outcomes of CVC-associated CVS have been disappointing, catheter avoidance remains the best strategy.

    A 5-year-old boy was diagnosed to have supravalvular aortic stenosis (SVAS). On evaluation of CT angiogram, there was associated bovine aortic arch (BAA). Association of BAA with SVAS has not been previously reported in literature, and to best of our knowledge, this is the first case report of SVAS with BAA. Recent studies show BAA as a marker for aortopathy. SVAS is also an arteriopathy. In light of this, SVAS can also possibly be a manifestation of aortopathy associated with BAA.

    We examined perinatal factors in relation to the rise in incidence of infantile hypertrophic pyloric stenosis among children in Olmsted County, Minnesota, during the period from 1950 through 1984. Primogeniture was associated with male infants but not female infants; some factor related to primogeniture, such as breast-feeding, may be etiologically important. Our data did not support a role for maternal disease, use of doxylamine succinate-pyridoxide hydrochloride (Bendectin), or an infectious process. Further study should be directed toward environmental factors associated with primogeniture.

    Atherosclerotic renal artery stenosis (ARAS) remains a major cause of secondary hypertension and renal failure. Randomized, prospective trials show that medical treatment should constitute the main therapeutic approach in ARAS. Regardless of intensive treatment and adequate blood pressure control, however, renal and extra-renal complications are not uncommon. Yet, the precise mechanisms, accurate detection, and optimal treatment in ARAS remain elusive. Strategies oriented to early detection and targeting these pathogenic pathways might prevent development of clinical endpoints. Here, we review the results of recent clinical trials, current understanding of the pathogenic mechanisms, novel imaging techniques to assess renal damage in ARAS, and treatment options.

    Introduction The aim of this study was to stratify anastomotic strictures (AS) following esophageal atresia (EA) repair and to establish predictors for the need of dilations. Material and Methods A retrospective study on children operated on for EA between 2004 and 2014 was conducted. The stricture index (SI) was measured both radiologically (SIXR) and endoscopically (SIEND). A correlation analysis between the SI and the number of dilations was performed using Spearman's test and linear regression analysis. Results In this study, 40 patients were included: 35 (87.5%) presented with Gross's type C EA, 3 (7.5%) type A, 1 (2.5%) type B, and 1 (2.5%) type D. The mean follow-up time was 101 ± 71.1 months (range: 7.8-232.5, median: 97.6). The mean SIXR was 0.56 ± 0.16 (range: 0.15-0.86). The mean SIEND was 0.45 ± 0.22 (range: 0.15-0.85). Twenty-four patients (60%) underwent a mean of 2 endoscopic dilations (range: 1-9). The number of dilations was poorly correlated with SIXR, while significantly correlated with SIEND. Patients who did not need dilations had a SIEND < 0.33, patients who needed only one dilation had 0.33 ≤ SIEND < 0.44, and those with SIEND ≥ 0.44 needed two or more dilations. No significant association with other clinical variables was found. All patients were asymptomatic at the time of the first endoscopy. Conclusion SIEND is a useful tool to classify AS and can represent a predictor of the need for endoscopic dilation. The role of the SIEND becomes even more important as clinical characteristics have a low predictive value for the development of an AS and the need for subsequent endoscopic esophageal dilatations.

    In the evaluation of esophageal disease, the appropriate question must be asked before the correct tests can be selected. Reflux can be demonstrated by radiologic methods, pH testing or radioisotopic techniques. Esophageal mucosal damage is best evaluated by x-ray, endoscopy, or biopsy. Chest pain is demonstrated by acid infusion or by manometry. Two algorithms are presented for the evaluation of chest pain and reflux symptoms.

    Total laryngectomy for cancer can result in dysphagia and altered esophageal motility. Manometric changes in the upper esophageal sphincter (UES), and in proximal and distal esophageal function have been reported. However, most studies have failed to take into account radiation therapy and appropriate controls. We selected ten male patients (54.3 +/- 1.9 yr) for longitudinal manometric evaluation prior to laryngectomy then at two weeks and again six months later. No patient received preoperative radiation therapy, had a previous history of esophageal surgery, or developed a postoperative wound infection or fistula. Seven of ten patients had positive nodes and received 6,000-6,600 rads postoperative radiation therapy. Preoperatively 4 of 10 patients complained of dysphagia which did not significantly change following surgery and radiation. Two of three patients who did not complain of dysphagia preoperatively and received radiation postoperatively developed dysphagia. No patient without dysphagia preoperatively who received no radiation therapy developed symptoms. Our studies show that laryngectomy causes alterations in the UES resting and peak pressures but not in the proximal or distal esophagus, or the lower esophageal sphincter. These data also imply radiation therapy may be associated with progressive alterations in motility and symptomatology. Further study regarding the effects of radiation on esophageal motility and function are urged.

    Achalasia is a rare esophageal motility disorder that is usually idiopathic in origin. It is characterized by dysphagia, and patients often have chest pain, regurgitation, weight loss, and an abnormal barium radiograph showing esophageal dilation with narrowing at the gastroesophageal junction. Abnormal or absent esophageal peristalsis and impaired relaxation of the lower esophageal sphincter (LES) are typically seen on esophageal manometry. The advent of high resolution manometry (HRM) has allowed more precise diagnosis of achalasia, subtype designation, and differentiation from other esophageal motor disorders with an initial seminal publication in 2008 followed by further refinements of what has been termed the Chicago classification. Potential treatments include drugs, endoscopic botulinum toxin injection, balloon dilation, traditional surgery (usually laparoscopic Heller myotomy; LHM), and a novel, less invasive, natural orifice transluminal endoscopic surgery (NOTES) approach to Heller myotomy termed peroral endoscopic myotomy (POEM). The first human POEM was performed in 2008, with the first publication appearing in 2010 and evidence now rapidly accumulating showing POEM to be comparable to traditional surgery in terms of clinical success and radiologic and manometric post-therapy outcomes. This review discusses the diagnosis and management of achalasia with particular emphasis on the recent developments of HRM and POEM, which arguably represent the most important advances in the field since the advent of laparoscopic Heller myotomy in the 1990s.

    Purpose. To evaluate the relationship between internal carotid artery (ICA) stenosis and subfoveal choroidal thickness (SFCT) in the elderly population. Methods. A total of 42 eyes of 21 patients with more than 70% ICA stenosis (Group 1) on one side and less than 70% stenosis (Group 2) on the other side were recruited for this study. ICA stenosis was diagnosed using both the B-mode and Doppler ultrasound. The two groups were compared in terms of the percentage of stenosis, SFCT measurements, intraocular pressure, ocular perfusion pressure, refractive error, and peak systolic velocity. Eyes were examined with the RTVue-100 OCT device by the EDI-OCT technique. Results. The mean age of the patients was 71.9 ± 10.8 years. The mean percentage of ICA stenosis was 74 ± 4.9% in Group 1 and 47.5 ± 7.7% in Group 2. The mean SFCT was 231.9 ± 44.6 μm in Group 1 and 216.2 ± 46.8 μm in Group 2, which was significantly lower (P = 0.028). A statistically significant positive correlation was found between the percentage of internal carotid artery stenosis and SFCT (r = 0896, P = 0.001). Conclusions. Compensatory SFCT increase can be seen in ipsilateral internal carotid artery stenosis greater than 70%. PMID:26989500

    Esophageal cancer (EC) is the fourth leading cause of cancer death in China. Despite a lot of advances in diagnosis and therapy, the survival rate of patients with EC is low. There is urgent need for a variety of methods and techniques to improve the survival time and alleviate the lesions of EC. Nowadays, alternative and less invasive approaches to the treatment of ECs are being identified. Here, we review several main interventional methods at different stages of EC, including endoscopic resection, stent placement, arterial infusion, photodynamic therapy, and radiofrequency ablation. This review will focus on the indications, methods, clinical outcomes, and complications of these methods, which may help guide the way forward. PMID:27904858

    Of the patients enrolled in the Japanese Registry of Neuroendovascular Therapy (JR-NET), a surveillance study in Japanese, 1133 patients who underwent intracranial percutaneous transluminal angioplasty (PTA)/stenting for intracranial stenosis during the period from 2005 to 2009 were investigated. A technical success was achieved in 98.3% of the patients, and 70.5% and 7.5% had a residual stenosis of < 30% and ≥ 50%, respectively. The incidence of ischemic complications and hemorrhagic complications was as low as 7.7% and 2.5%, respectively, but tended to increase in patients who underwent stenting. While a significant correlation with ischemic complications was observed in previously untreated patients and patients who underwent stenting followed by post-dilatation, a significant correlation with hemorrhagic complications was observed in patients who received emergency treatment and those treated between 24 hours and 14 days of the onset. Flexible intracranial stents are expected to contribute to improvement in the treatment outcome. PMID:24390191

    Esophageal intramural pseudodiverticulosis (EIPD) is a rare, benign condition of uncertain etiology and pathogenesis, which usually presents with either progressive or intermittent dysphagia. Acute presentation with food impaction, requiring emergency esophago-gastroduodenoscopy (EGD), is rare. We report a case of EIPD presenting as food bolus impaction in an elderly black female. The patient had no previous history of dysphagia or odynophagia. Currently accepted risk factors, such as diabetes mellitus, chronic alcoholism, and reflux esophagitis, were not present in our patient. Emergency EGD established the diagnosis and also dislodged the food bolus. Histopathological evaluation of the mucosa diagnosed co-existent acute candidal infection. Medical treatment with proton pump inhibitor and azole antifungal led to resolution of her symptoms. Review of the literature revealed that stenosis, strictures, perforation, gastro-intestinal bleed, and fistula formation are potential complications of EIPD. Multiple motility abnormalities have been described but are not consistent. Treatment of the underlying inflammatory and or infectious condition is the mainstay of management of this unusual condition. PMID:24951515

    A 21 year old male was discovered to be severely hypertensive. He was found to have bilateral adrenal phaeochromocytomas and a single renal artery stenosis. More than 40 cases of coexisting renal artery stenosis and phaeochromocytomas have been reported. The aetiology of renal artery stenosis in association with phaeochromocytoma maybe multifactorial and the radiographic appearances are not always clear-cut. Renin levels in this patient were elevated prior to the removal of the phaeochromocytomas but the renal vein renin ratio did not suggest that the renal artery stenosis contributed significantly to his hypertension. The patient's hypertension resolved following successful removal of the phaeochromocytomas despite persistence of the renal artery stenosis. Thus, though renin levels may be misleading in these cases, renal vein renin ratios may still be helpful in deciding on patient management. Images Figure 1 Figure 2 PMID:2694147

    Pulmonary vein stenosis is a well-established possible complication following an atrial fibrillation ablation of pulmonary veins. Symptoms of pulmonary vein stenosis range from asymptomatic to severe exertional dyspnea. The number of asymptomatic patients with pulmonary vein stenosis is greater than originally estimated; moreover, only about 22% of severe pulmonary vein stenosis requires intervention. We present a patient with severe postatrial fibrillation (AF) ablation pulmonary vein (PV) stenosis, which was seen on multiple imaging modalities including cardiac computed tomography (CT) angiogram, lung perfusion scan, and pulmonary angiogram. This patient did not have any pulmonary symptoms. Hemodynamic changes within a stenosed pulmonary vein might not reflect the clinical severity of the obstruction if redistribution of pulmonary artery flow occurs. Our patient had an abnormal lung perfusion and ventilation (V/Q) scan, suggesting pulmonary artery blood flow redistribution. The patient ultimately underwent safe repeat atrial fibrillation ablation with successful elimination of arrhythmia. PMID:28105376

    In 30 patients with syndrome X, esophageal motility was evaluated by radionuclide esophageal transit test (RETT). Esophageal motility measurements included esophageal mean transit time (MTT), residual fraction (RF), and retrograde index (RI). In comparison with 25 age- and sex-matched healthy volunteers, 66% of the patients with syndrome X had abnormal RETT findings including 50% of cases with longer MTT, 50% of cases with higher RF, and 33% of cases with higher RI. In addition, the mean values of MTT, RF, and RI in patients with syndrome X were significantly higher than those of healthy volunteers. We conclude that abnormal esophageal motility occurred in a large portion of syndrome X patients based on an simple and noninvasive RETT.

    OBJECTIVES: To assess the effects of chronic xerostomia on parameters of gastroesophageal reflux and esophagitis. DESIGN: Observational study of a cohort of male patients with xerostomia and age-matched control subjects. SETTING: Tertiary-care Veterans Affairs Medical Center. SUBJECTS: Sixteen male patients with chronic xerostomia secondary to radiation for head and neck cancers or medications. Nineteen age-matched male control subjects with comparable alcohol and smoking histories. MEASUREMENTS AND MAIN RESULTS: Esophageal motility was similar in patients with xerostomia and controls. Clearance of acid from the esophagus and 24-hour intraesophageal pH were markedly abnormal in patients with xerostomia. Symptoms and signs of esophagitis were significantly more frequent in subjects with xerostomia. CONCLUSIONS: Chronic xerostomia may predispose to esophageal injury, at least in part, by decreasing the clearance of acid from the esophagus and altering 24-hour intraesophageal pH. Esophageal injury is a previously unreported complication of long-term salivary deficiency.

    Eosinophilic esophagitis (EoE) is a relatively new condition resulting in dysphagia or symptoms resembling gastroesophageal reflux disease, symptoms that also are common in patients with a history of esophageal atresia. We present 2 patients with persistent dysphagia after repair of esophageal atresia that was caused by EoE. Although the exact etiology and pathogenesis of EoE remain unclear, it is now generally accepted that it is the result of a T-helper cell 2-type immune response with a crucial role for the eosinophil-specific chemotaxis factor eotaxin 3 and eosinophils. Because there are genetic similarities between esophageal atresia and EoE, we speculate that patients with esophageal atresia are at increased risk for developing EoE.

    Esophageal distension causes simultaneous relaxation of the lower esophageal sphincter (LES) and crural diaphragm. The mechanism of crural diaphragm relaxation during esophageal distension is not well understood. We studied the motion of crural and costal diaphragm along with the motion of the distal esophagus during esophageal distension-induced relaxation of the LES and crural diaphragm. Wire electrodes were surgically implanted into the crural and costal diaphragm in five cats. In two additional cats, radiopaque markers were also sutured into the outer wall of the distal esophagus to monitor esophageal shortening. Under light anesthesia, animals were placed on an X-ray fluoroscope to monitor the motion of the diaphragm and the distal esophagus by tracking the radiopaque markers. Crural and costal diaphragm electromyograms (EMGs) were recorded along with the esophageal, LES, and gastric pressures. A 2-cm balloon placed 5 cm above the LES was used for esophageal distension. Effects of baclofen, a GABA(B) agonist, were also studied. Esophageal distension induced LES relaxation and selective inhibition of the crural diaphragm EMG. The crural diaphragm moved in a craniocaudal direction with expiration and inspiration, respectively. Esophageal distension-induced inhibition of the crural EMG was associated with sustained cranial motion of the crural diaphragm and esophagus. Baclofen blocked distension-induced LES relaxation and crural diaphragm EMG inhibition along with the cranial motion of the crural diaphragm and the distal esophagus. There is a close temporal correlation between esophageal distension-mediated LES relaxation and crural diaphragm inhibition with the sustained cranial motion of the crural diaphragm. Stretch caused by the longitudinal muscle contraction of the esophagus during distension of the esophagus may be important in causing LES relaxation and crural diaphragm inhibition.

    AIM: To analyze the clinical and dosimetric predictive factors for radiation-induced esophageal injury in patients with non-small-cell lung cancer (NSCLC) during three-dimensional conformal radiotherapy (3D-CRT). METHODS: We retrospectively analyzed 208 consecutive patients (146 men and 62 women) with NSCLC treated with 3D-CRT. The median age of the patients was 64 years (range 35-87 years). The clinical and treatment parameters including gender, age, performance status, sequential chemotherapy, concurrent chemotherapy, presence of carinal or subcarinal lymph nodes, pretreatment weight loss, mean dose to the entire esophagus, maximal point dose to the esophagus, and percentage of volume of esophagus receiving >55 Gy were studied. Clinical and dosimetric factors for radiation-induced acute and late grade 3-5 esophageal injury were analyzed according to Radiation Therapy Oncology Group (RTOG) criteria. RESULTS: Twenty-five (12%) of the two hundred and eight patients developed acute or late grade 3-5 esophageal injury. Among them, nine patients had both acute and late grade 3-5 esophageal injury, two died of late esophageal perforation. Concurrent chemotherapy and maximal point dose to the esophagus ≥60 Gy were significantly associated with the risk of grade 3-5 esophageal injury. Fifty-four (26%) of the two hundred and eight patients received concurrent chemotherapy. Among them, 25 (46%) developed grade 3-5 esophageal injury (P = 0.0001<0.01). However, no grade 3-5 esophageal injury occurred in patients who received a maximal point dose to the esophagus <60 Gy (P = 0.0001<0.01). CONCLUSION: Concurrent chemotherapy and the maximal esophageal point dose ≥60 Gy are significantly associated with the risk of grade 3-5 esophageal injury in patients with NSCLC treated with 3D-CRT.

    INTRODUCTION Blunt esophageal injury is extremely rare event. However, it is a potential morbid injury unless managed early. PRESENTATION OF CASE We report a rare case of blunt esophageal injury for a 28-year old male who presented with history of fall of heavy object over the right side of the chest. Diagnostic work up including chest X-ray, computerized tomography scans and gastrografin esophagogram revealed lower esophageal rupture. Right mini-thoracotomy with esophageal repair was performed. Postoperative course was uneventful. DISCUSSION The exact mechanism of blunt esophageal injury remains uncertain. This report described a unique location of esophageal rupture after blunt trauma that happened on the right side. Diagnosis of esophageal injury needs high index of suspicion and accurate diagnostic workup. CONCLUSION Prompt diagnosis and management are the key for better prognosis in patients with blunt esophageal injury. PMID:24394856

    Esophageal achalasia is often associated with esophageal cancer. However, in many cases, esophageal cancer tends to be found in an advanced stage, with a poor prognosis. However, early-stage cancer was detected recently due to the advances in endoscopic instruments. In those cases, it is important to facilitate successful treatment by endoscopic submucosal dissection. We analyzed a total of six cases of esophageal cancer with achalasia in four patients treated with endoscopic submucosal dissection. Three features common to all six cases had a bearing on how endoscopic submucosal dissection was performed. First, esophageal dilatation and diminished peristalsis facilitated the performance of successful endoscopic submucosal dissection. Second, the esophageal wall was thickened, primarily with muscular tissue. Third, the submucosal layer contained abundant blood vessels that made it difficult to minimize bleeding during dissection. Those findings suggest that endoscopic submucosal dissection for early esophageal cancer associated with achalasia is a safe and potentially curative procedure. It is important, therefore, to detect esophageal cancer early.

    We report a case of aorto-bronchial fistula (ABF) caused by a self-expanding metallic stent (EMS) 51 days after insertion into the left main bronchus. The patient presented with left main bronchial stenosis caused by post-operative local recurrence of esophageal cancer. Post-operative radio therapy totaling 40 Gy and post-recurrence radiotherapy totaling 34 Gy were administered, with daily fractions of 2 Gy. Stenosis of the left main bronchus improved slightly, and was followed with insertion of EMS to prevent re-stenosis. The patient experienced massive hemoptysis for 3 days before sudden death. Autopsy revealed the EMS edge perforating the descending aortic lumen. Tumor infiltration and bacterial infection were observed on the wall of the left bronchus, and atherosclerosis was present on the aortic wall around the fistula. It should be noted that the left main bronchus was at considerable risk of ABF after insertion of EMS for malignant stenosis, and prophylactic stent insertion into the bronchus without imperative need must be avoided.

    Esophageal cancer is one of the top leading causes of cancer-related deaths in Malaysia. To date, neither the prevalence nor incidence of esophageal cancer nationally have been recorded. Esophageal cancer remains a major and lethal health problem even if it is not common in Malaysia. The late presentation of esophageal cancer makes it a difficult and challenging medical problem. Therefore, more governmental and non-governmental organizations of Malaysia should emphasize primary and secondary prevention strategies.

    Eosinophilic and herpetic esophagitis are listed as independent causes of dysphagia, especially in young adult males. However, herpetic esophagitis rarely affects immunocompetent individuals. We report the case of a young, not immunocompromised patient, admitted because of severe dysphagia secondary to herpes simplex virus esophagitis. After complete resolution, an endoscopic and histologic reevaluation established the diagnosis of eosinophilic esophagitis. The potential association between the two conditions is discussed.

    Esophageal squamous cell carcinoma (SCC) is responsible for approximately one-sixth of all cancer-related mortality worldwide. This malignancy has a multifactorial etiology involving several environmental, dietary and genetic factors. Since esophageal cancer has often metastasized at the time of diagnosis, current treatment modalities offer poor survival and cure rates. Chemoprevention offers a viable alternative that could well be effective against the disease. Clinical investigations have shown that primary chemoprevention of this disease is feasible if potent inhibitory agents are identified. The Fischer 344 (F-344) rat model of esophageal SCC has been used extensively to investigate the biology of the disease, and to identify chemopreventive agents that could be useful in human trials. Multiple compounds that inhibit tumor initiation by esophageal carcinogens have been identified using this model. These include several isothiocyanates, diallyl sulfide and polyphenolic compounds. These compounds influence the metabolic activation of esophageal carcinogens resulting in reduced genetic (DNA) damage. Recently, a few agents have been shown to inhibit the progression of preneoplastic lesions in the rat esophagus into tumors. These agents include inhibitors of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), vascular endothelial growth factor (VEGF) and c-Jun [a component of activator protein-1 (AP-1)]. Using a food-based approach to cancer prevention, we have shown that freeze-dried berry preparations inhibit both the initiation and promotion/progression stages of esophageal SCC in F-344 rats. These observations have led to a clinical trial in China to evaluate the ability of freeze-dried strawberries to influence the progression of esophageal dysplasia to SCC.

    An 8-week-old male domestic shorthair was presented to the Internal Medicine Service at North Carolina State University for regurgitation. Radiographic diagnosis of generalized esophageal dilation and failure of esophageal peristalsis were compatible with diagnosis of congenital megaesophagus. Endoscopic examination of the esophagus revealed a fibrous stricture just orad to the lower esophageal sphincter. Conservative management to increase the body condition and size of the kitten consisted of feeding through a gastrostomy tube, during which time the esophagus regained normal peristaltic function, the stricture orifice widened in size and successful balloon dilatation of the stricture was performed. Esophageal endoscopy should be considered to rule out a stricture near the lower esophageal sphincter in kittens with radiographic findings suggestive of congenital megaesophagus. Management of such kittens by means of gastrostomy tube feeding may be associated with a return of normal esophageal motility and widening of the esophageal stricture, and facilitate subsequent success of interventional dilation of the esophageal stricture.

    Satisfactory palliation of the lesions involving the carinal region is difficult to achieve because the stenting is conducted in an unsuitable anatomy, in highly symptomatic patients. During the period 1987-2000 we performed 785 operative rigid bronchoscopies in 524 patients, 184 of whom received a respiratory stent. The stenting of the carinal region was carried out in 27 patients with the use of the Frietag Dynamic stent. In this group of patients indication for stenting was as follows:--advanced lung cancer (22);--esophageal cancer invading the lower trachea (1);--severe tracheobronchomalacia (2);--postintubation stenosis of the lower trachea (2). No perioperative mortality was observed. All patients experienced symptomatic improvement. Follow-up ranged from 1 to 60 months: all neoplastic patients died for advanced disease without significant respiratory problems with a median survival of 5.6 months; three patients treated for benign diseases are still alive at 2, 31 and 65 months from stent deployment. No major complications were observed: in two patients the stent was removed after few days due to mucous retention; furthermore we observed symptomatic respiratory infections caused by a residual space between the tracheal wall and the prosthesis in other two patients with severe COPD. Dynamic stent is to be considered the stent of choice for palliation of the carinal region because it is effective and well tolerated with a low complications rate. The main limitations of such prosthesis are the shortness of the right bronchial branch and the size, sometimes inadequate.

    Pulmonary vein stenosis (PVS) is rare condition characterized by a challenging diagnosis and unfavorable prognosis at advance stages. At present, injury from radiofrequency ablation for atrial fibrillation has become the main cause of the disease. PVS is characterized by a progressive lumen size reduction of one or more pulmonary veins that, when hemodynamically significant, may raise lobar capillary pressure leading to signs and symptoms such as shortness of breath, cough, and hemoptysis. Image techniques (transesophageal echocardiography, computed tomography, magnetic resonance and perfusion imaging) are essential to reach a final diagnosis and decide an appropriate therapy. In this regard, series from referral centers have shown that surgical and transcatheter interventions may improve prognosis. The purpose of this article is to review the etiology, assessment and management of PVS.

    Reports of self-enucleation are frequent in medical literature, but cases of enucleation towards another are rare. We report the case of a man, 20 years of age, who suffered from psychosis with hydrocephalus and aqueductal stenosis that required a forensic psychiatric investigation to ascertain whether he was of unsound mind when he assaulted and enucleated the right eye of an officer and led to the surgical enucleation of the victim's left eye. Based on his clinical interviews and hospitalization record, we conclude that at the time of the assault, he was suffering from a delusional disorder with religious and demonic content, visual and auditory hallucinations, illusion phenomena, delusional interpretations, imaginative elements, a feeling of terror, and command hallucinations that compelled him to perform the act of aggression.

    Introduction. Postsurgical nasopharyngeal airway stenosis can be a challenge to manage. The stenosis could be as a result of any surgical procedure in the nasopharyngeal region that heals extensive scarring and fibrosis. Objective. To evaluate patients with nasopharyngeal stenosis managed with FAMM flap. Study Design. Prospective study of patients with nasopharyngeal stenosis at the Kenyatta National Hospital between 2010 and 2013 managed with FAMM flap. Materials and Methods. Patients with severe nasopharyngeal airway stenosis were reviewed and managed with FAMM flaps at the Kenyatta National Hospital. Postoperatively they were assessed for symptomatic improvement in respiratory distress, patency of the nasopharyngeal airway, and donor site morbidity. Results. A total of 8 patients were managed by the authors in a duration of 4 years with nasopharyngeal stenosis. Five patients were managed with unilateral FAMM flaps in a two-staged surgical procedure. Four patients had complete relieve of the airway obstruction with a patent airway created. One patient had a patent airway created though with only mild improvement in airway obstruction. Conclusion. FAMM flap provides an alternative in the management of postsurgical severe nasopharyngeal stenosis. It is a reliable flap that is easy to raise and could provide adequate epithelium for the stenosed pharynx. PMID:25328699

    Esophageal food bolus impaction may require an urgent endoscopy. Glucagon is often administered to promote spontaneous passage of the food bolus. Eosinophilic esophagitis is increasingly recognized as a cause of dysphagia, and food impaction is often the presenting symptom. Our study was aimed at determining the effectiveness of glucagon in relieving esophageal foreign body obstruction in general and in the setting of esophageal eosinophilic infiltration (EEI). A retrospective chart review was performed using the ICD codes and the emergency department database of adult patients presenting with symptoms of esophageal food bolus impaction from July 2004 to October 2010. Response to glucagon was defined as symptomatic relief of obstruction prior to endoscopic intervention. A total of 213 episodes of esophageal food bolus obstruction in 192 patients were identified during the study period. Glucagon was given in 125 cases of which 41 had a response (32.8 %). A total of 170 episodes had an Esophagogastroduodenoscopy performed either during the impaction event or at a later date. Of the 60 patients' biopsies, 45 had received glucagon (17 with EEI, 28 without EEI). None of the 17 episodes with EEI as compared to 8 of the 28 without EEI responded to glucagon (0 % vs. 28.5 %, p = 0.017). Glucagon is effective in about one third of patients with esophageal food bolus impaction, which is consistent with historical data. Patients with EEI appear less likely to respond to glucagon.

    The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

    Perforation of esophagus in the adult is a very morbid condition with high morbidity and mortality. The ideal treatment is controversial. The main causes for esophageal perforation in adults are iatrogenic, traumatic, spontaneous and foreign bodies. The morbidity and mortality rate is directly related to the delay in diagnosis and initiation of optimum treatment. The reported mortality from treated esophageal perforation is 10% to 25%, when therapy is initiated within 24 hours of perforation, but it could rise up to 40% to 60% when the treatment is delayed beyond 48 hours. Primary closure of the perforation site and wide drainage of the mediastinum is recommended if perforation is detected in less than 24 hours. Treatment option for delayed or missed rupture of esophagus is not very clear and is controversial. Recently a substantial number of patients with esophageal perforation are being managed by nonoperative measures. Patients with small perforations and minimal extraesophageal involvement may be better managed by nonoperative treatment Major prognostic factors determining mortality are the etiology and site of the injury, the presence of underlying esophageal pathology, the delay in diagnosis and the method of treatment. For optimum outcome for management of esophageal perforations in adults a multidisciplinary approach is needed. PMID:27942303

    Esophageal cancer is a deadly disease, ranking sixth among all cancers in mortality. Despite incremental advances in diagnostics and therapeutics, esophageal cancer still carries a poor prognosis, and thus there remains a need to elucidate the molecular mechanisms underlying this disease. There is accumulating evidence that a comprehensive understanding of the molecular composition of esophageal cancer requires attention to not only tumor cells but also the tumor microenvironment, which contains diverse cell populations, signaling factors, and structural molecules that interact with tumor cells and support all stages of tumorigenesis. In esophageal cancer, environmental exposures can trigger chronic inflammation, which leads to constitutive activation of pro-inflammatory signaling pathways that promote survival and proliferation. Anti-tumor immunity is attenuated by cell populations such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs), as well as immune checkpoints like programmed death-1 (PD-1). Other immune cells such as tumor-associated macrophages can have other pro-tumorigenic functions, including the induction of angiogenesis and tumor cell invasion. Cancer-associated fibroblasts secrete growth factors and alter the extracellular matrix (ECM) to create a tumor niche and enhance tumor cell migration and metastasis. Further study of how these TME components relate to the different stages of tumor progression in each esophageal cancer subtype will lead to development of novel and specific TME-targeting therapeutic strategies, which offer considerable potential especially in the setting of combination therapy.

    The delayed upstroke of the arterial pulse in valvular aortic stenosis has been attributed, in part, to prolonged left ventricular emptying. Left ventricular emptying rate, however, has not been measured in aortic stenosis. We assessed the rate of left ventricular emptying by computer analysis of biplane cineangiograms in seven normal subjects, six patients with mild to moderate aortic stenosis, and 12 patients with severe aortic stenosis. As an indicator of delayed arterial pulse rise, T time index (time to half maximum aortic pressure corrected for heart rate) was measured in each group. T time index averaged 0.07 +/- 0.01 units in normal subjects, 0.14 +/- 0.04 units in the patients with mild to moderate aortic stenosis, and 0.13 +/- 0.05 units in those with severe aortic stenosis. Patients with mild to moderate and severe aortic stenosis differed significantly from normal subjects. Relative emptying rates were defined as the percentage of initial systolic volume ejected divided by the percentage of systole elapsed. These relative emptying rates were determined during the first, second, and third thirds of systole in all three groups. No significant decrease in the relative rate of left ventricular emptying was noted when each group of patients with aortic stenosis was compared with the normal subjects. Neither was there slowing in the actual rate of ejection of blood in ml per second throughout systole. We conclude that the rate of ventricular emptying is normal in aortic stenosis and does not explain the arterial pulse delay in this disease. PMID:7295438

    Background/Aims Disturbances of esophageal motility have been reported to be more frequent the aged population. However, the physiology of disturbances in esophageal motility during aging is unclear. The aim of this study was to evaluate the effects of age on esophageal motility using high-resolution esophageal impedance manometry (HRIM). Methods Esophageal motor function of 268 subjects were measured using HRIM in 3 age groups, < 40 years (Group A, n = 32), 40–65 years (Group B, n = 185), and > 65 years (Group C, n = 62). Lower esophageal sphincter (LES) and upper esophageal sphincter (UES) pressures, integrated relaxation pressure, distal contractile integral, contractile front velocity, distal latency, and pressures and duration of contraction on 4 positions along the esophagus, and complete bolus transit were measured. Results Basal UES pressure was lower in Group C (P < 0.001) but there was no significant difference in the LES pressure among groups. Contractile duration on position 3 (10 cm from proximal LES high pressure zone) was longer in Group C (P = 0.001), and the contractile amplitude on position 4 (5 cm from proximal LES high pressure zone) was lower in Group C (P = 0.005). Distal contractile integral was lower in Group C (P = 0.037). Contractile front velocity (P = 0.015) and the onset velocity (P = 0.040) was lower in Group C. There was no significant difference in impedance values. Conclusions The decrease of UES pressure, distal esophageal motility, and peristaltic velocity might be related with esophageal symptoms in the aged population. PMID:28163259

Proper selection of surgical technique in each clinical setting is the key for successful outcome. The purpose of this article is to guide one in selection of appropriate surgical procedures depending upon various stenosis parameters. Aim To record the clinical profile of cases with LTS. To assess the outcome following various surgical interventions based on site, severity, cause of stenosis and to derive conclusions regarding treatment options in various stenosis. Materials and Methods It is a study of 60 cases with chronic LTS. It includes retrospective study of 30 cases treated from 2004 and prospective study of 30 cases from Jan 2007 to Dec 2009. A total of 60 cases with LTS were enrolled in the study. Patients were assessed clinically by eliciting detailed history and analyzing previous records. After assessment of extent of stenosis, they were subjected to surgical interventions (endoscopic/open approach). Outcome after surgical interventions was assessed. Results 60 patients were included in the study, in the age group of 2.5-50 years. There were 46 (77%) male patients and 14 (23%) female patients. Intrinsic trauma, secondary to prolonged intubation was the most common cause of LTS, seen in 23 (38%) cases followed by post traumatic stenosis (strangulation-18 (30%), blunt injury-15 (25%), penetrating neck injury-4 (7%)). Stenosis was divided into 6 types based on subsite involvement. Of which, cervical trachea was the commonest site of involvement (25/60 cases). Majority of cases had fixed vocal cords at presentation (55%), more commonly due to post traumatic injury. 60 cases had undergone a total of 110 surgical procedures (endoscopic-56,open approach-54). In the end, overall decannulation rate is 93.3%. In site wise tracheal stenosis, isolated subglottis, combined glottis and subglottic stenosis had decannulation rate of 100% each and

    The risk associated with repeated treatment of aortic stenosis is as high as 5% and increases to as much as 25% in complex heart diseases. Among the methods that are commonly accepted and used in the treatment of recurrent aortic stenosis are balloon dilatation and stent implantation. In this study we describe five patients with recurrent stenosis of the aorta treated with stent implantation. The short-term results of such treatment are promising. However, in some cases it is only palliative in character and does not completely resolve the problems arising from congenital heart disease. (Cardiol J 2007; 14: 186-192).

    Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by symptoms of esophageal dysfunction and eosinophilic infiltration of the esophageal mucosa. The diagnosis requires esophageal biopsies demonstrating at least 15 eosinophils per high-powered field following a course of high-dose proton pump inhibitors. Management of EoE consists of the three Ds: drugs, dietary therapy, and esophageal dilation. In this review, we discuss the epidemiology, pathogenesis, diagnosis, and treatment of EoE to include the role of emerging therapies. PMID:26986655

    Precise tumor-staging is critical in the management of early esophageal caner. Endoscopic ultrasound (EUS) allows the endoscopist a view beyond the esophageal wall which opens the door to a variety of new gastroenterologic techniques. Endoscopic mucosal resection, laser photoablation and photodynamic therapy may be successfully employed in early esophageal cancer management. Combination radiation therapy and chemotherapy have shown better responses in advanced cancer. Expandable metallic stents may also provide palliation with inoperable esophageal cancer. The efficacy of EUS in the management of esophageal cancer is critically reviewed.

    2016-01-25

    Achalasia is a motility disorder of the esophagus characterized by dysphagia, regurgitation of undigested food, chest pain, weight loss and respiratory symptoms. The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry (HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type II achalasia are better after treatment compared to younger patients, males and type III achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies.

    There have been some breakthroughs in the diagnosis and treatment of esophageal achalasia in the past few years. First, the introduction of high-resolution manometry with pressure topography plotting as a new diagnostic tool has made it possible to classify achalasia into three subtypes. The most favorable outcome is predicted for patients receiving treatment for type II achalasia (achalasia with compression). Patients with type I(classic achalasia) and type III achalasia (spastic achalasia) experience a less favorable outcome. Second, the first multicenter randomized controlled trial published by the European Achalasia Trial group reported 2-year follow-up results indicating that laparoscopic Heller myotomy was not superior to endoscopic pneumatic dilation (PD). Although the follow-up period was not long enough to reach a convincing conclusion, it merits the continued use of PD as a generally available technique in gastroenterology. Third, the novel endoscopic technique peroral endoscopic myotomy is a promising option for treating achalasia, but it requires increased experience and cautious evaluation. Despite all this good news, the bottom line is a real breakthrough from the basic studies to identify the actual cause of achalasia that may impede treatment success is still anticipated.

    Rhabdomyomatous well-differentiated esophageal liposarcomas are extremely rare. As of August 2016, only one other such case has been reported in the English-language medical literature. Liposarcomas in general are one of the most common soft tissue neoplasms in adults, but the incidence of primary esophageal liposarcomas is exceptionally low. There have been only 42 reported cases of primary liposarcoma of the esophagus worldwide thus far. These malignancies are harbored within giant fibrovascular polyps, which slowly grow within the esophageal lumen causing obstructing symptoms. We hereby present the case of a 68-year-old male patient who came in with a 2-mo history of worsening intermittent dysphagia, persistent cough, and postprandial retrosternal pain. After an esophagogastroduodenoscopy, a computed tomographic scan, and a diagnostic endoscopy, complete endoscopic resection was performed of the 13 cm × 6 cm × 2.6 cm fibrovascular polyp. A literature review was done and results are presented herein. PMID:28035254

    Five patients with early esophageal carcinoma were treated by 6-12 Gy of intracavitary irradiation following 50-60 Gy of external irradiation as a boost therapy. Surgery was not performed in these cases. None of the patients had local recurrence after radiation therapy, as demonstrated by esophagography and endoscopy. Three patients have been alive for 1-3 years 10 months. Esophageal ulceration induced by intracavitary irradiation has occurred in three of the five patients; however, intracavitary irradiation is still a beneficial treatment because of its efficacy in controlling local lesions and because radiation ulceration can eventually be cured. Intracavitary irradiation is recommended to follow external irradiation as a boost therapy for the treatment of early esophageal carcinoma.

At presentation, the bone was dislodged at endoscopy; one round opening in a deep ulceration was detected when the fishbone was removed. The perforation was closed by endoscopic hemoclipping, after the removal of the fishbone. A thoracic computed tomography revealed air around the esophagus, aorta and bronchus and the presence of a pleural effusion. These findings suggested mediastinal emphysema and mediastinitis due to the esophageal perforation after the removal of the fishbone. Esophagography revealed a focal esophageal defect and linear contrast leakage at the distal esophagus. The mediastinal emphysema and pleural effusion successfully resolved after the endoscopic hemoclip application and conservative management of the perforation.

    A 39-year old man came to our outpatient clinic with long history of unspecific symptoms and signs. Cerebral MRI showed herniation of the cerebellar tonsils of more than 1 cm below the foramen magnum and a triventricular hydrocephalus. A diagnosis of Chiari I malformation was retained. After an osteo-dural decompression of the posterior fossa, post-operative MRI revealed an aqueductal stenosis with triventricular hydrocephalus. An endoscopic-third- ventriculostomy showed an idiopathic stenosis of the right foramen of Monro. Residual symptoms and persistence of biventricular hydrocephalus justified a ventriculo-peritoneal shunt. Aqueductal and foramina of Monro stenosis can mimick a Chiari I malformation.

    In Plummer-Vinson syndrome, esophagography often reveals a web at the anterior wall of the cervical esophagus. The pathogenesis of the esophageal web and the cause of dysphagia in this syndrome were investigated radiographically, endoscopically, manometrically, and histologically. It was considered that the web seen in the esophagogram may have been formed due to the restriction of dilation of the esophageal wall, which results from repetitive inflammation and the subsequent healing process. Dysphagia in this syndrome may be explained by a decrease in swallowing power. Iron deficiency anemia may play the main role in the above histological changes and the resulting decrease in swallowing power.

    Topical steroid therapy has been used to treat eosinophilic esophagitis (EoE) for more than 15 years. We review the treatment trials of topical steroid therapy in adult patients with EoE. Currently, there is no commercially available preparation designed to deliver the steroid to the esophagus. Current regimens consist of swallowing steroid preparations designed for inhalation treatment for asthma. In the short term, steroids are associated with an approximately 15% to 25% incidence of asymptomatic esophageal candidiasis, but otherwise appear to be well tolerated.

    Eosinophilic esophagitis is a worldwide chronic allergic disease of the esophagus. In the last decade, there is an epidemic of this entity in the western world. Mostly seen in children and young adults, patients present with dysphagia or food impaction in the emergency room. Characteristic endoscopic findings, esophageal eosinophilia and non-responsiveness to proton pump inhibitors help make the diagnosis. Avoidance of food allergens, administration of steroidal anti-inflammatory medications and dilation of the esophagus are the mainstays of treatment. Investigations are ongoing for mucosal healing and optimum maintenance treatment. PMID:27158535

  9. Subcoronary versus supracoronary aortic stenosis. an experimental evaluation

    PubMed Central

    2011-01-01

    Background Valvular aortic stenosis is the most common cause of left ventricular hypertrophy due to gradually increasing pressure work. As the stenosis develop the left ventricular hypertrophy may lead to congestive heart failure, increased risk of perioperative complications and also increased risk of sudden death. A functional porcine model imitating the pathophysiological nature of valvular aortic stenosis is very much sought after in order to study the geometrical and pathophysiological changes of the left ventricle, timing of surgery and also pharmacological therapy in this patient group. Earlier we developed a porcine model for aortic stenosis based on supracoronary aortic banding, this model may not completely imitate the pathophysiological changes that occurs when valvular aortic stenosis is present including the coronary blood flow. It would therefore be desirable to optimize this model according to the localization of the stenosis. Methods In 20 kg pigs subcoronary (n = 8), supracoronary aortic banding (n = 8) or sham operation (n = 4) was preformed via a left lateral thoracotomy. The primary endpoint was left ventricular wall thickness; secondary endpoints were heart/body weight ratio and the systolic/diastolic blood flow ratio in the left anterior descending coronary. Statistical evaluation by oneway anova and unpaired t-test. Results Sub- and supracoronary banding induce an equal degree of left ventricular hypertrophy compared with the control group. The coronary blood flow ratio was slightly but not significantly higher in the supracoronary group (ratio = 0.45) compared with the two other groups (subcoronary ratio = 0.36, control ratio = 0.34). Conclusions A human pathophysiologically compatible porcine model for valvular aortic stenosis was developed by performing subcoronary aortic banding. Sub- and supracoronary aortic banding induce an equal degree of left ventricular hypertrophy. This model may be valid for experimental investigations of aortic

    Objectives. To study the cerebral and central hemodynamics in patients with stenotic lesions of inner carotid arteries (ICA) before and after reconstructive surgery. Material and methods. Fifty-nine patients, aged from 46 to 78 years, with >50% atherosclerotic stenosis of ICA who underwent preventive carotid endarterectomy (CEAE) were examined. The isolate stenosis of ICA was identified in 13.6% of patients, concomitant lesions of brachiocephalic arteries in 86.4%. Atherosclerotic lesions of coronary arteries were found in 91.1% of patients and those of arteries of lower extremities in 45.8%. In 25.5% of patients, the heart surgery was performed before the current hospitalization. Heterogeneous atherosclerotic plaques with dense or hyperdense components were more frequents in symptomatic stenosis (63.3%). The maximal stenosis was identified in heterogeneous hyperechogenic plaques, the minimal ones in homogenous hypoechogenic plaques. Parameters of central hemodynamics were better in patients with 2nd stage of reconstructive surgeries. The emission fraction decreased proportionally to the degree of stenosis. The parameters of cerebral hemodynamics were significantly decreased in ICA stenosis and improved in the early post-surgery period. Results. CEAE promoted the improvement of cognitive functions and the recovery of motor functions. The best positive dynamics was recorded in asymptomatic ICA stenosis. Poor outcome (transitory ischemic attacks, urgent surgery, restenosis) was found in patients with low levels of central and cerebral hemodynamics 12-24 months after the discharge. Moreover, smoking and the degree of stenosis predicted poor outcome. Conclusions. Surgical treatment in combination with the complex pharmacotherapy (hypotensive drugs, antiaggregants and statins) had the maximal effect, including the remote period.

    There are several nonsurgical alternatives to treat radicular pain in degenerative lumbar spinal stenosis. Epidural steroid injections have been used for several decades, but the different studies have shown variable effects. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified nine systematic reviews including seven pertinent randomized controlled trials. We concluded epidural steroid injection probably leads to little or no effect on reducing radicular pain of spinal stenosis.

    Summary Introduction: This prospective study was planned to investigate the frequency and relationship of acquired von Willebrand syndrome (AVWS) with aortic and pulmonary stenosis in patients. Methods: A total of 84 children, ranging from two to 18 years of age, were enrolled in this study. Of these, 28 had isolated aortic stenosis, 32 had isolated pulmonary stenosis and 24 were healthy. Children with aortic and pulmonary stenosis associated with other congenital heart diseases were excluded. Children with hypothyroidism, renal or liver disease, malignancy or autoimmune disease were also excluded. Wholeblood count, blood group, factor VIII level, prothrombin time (PT), activated partial thromboplastin time (aPTT), von Willebrand factor antigen (VWF:Ag), ristocetin co-factor (VWF:RCo), and bleeding time using a platelet-function analyser (PFA-100) were performed in all patients. All of the children in the study underwent a detailed physical examination and echocardiographic evaluation. Results: A history of bleeding was positive in 18% of the aortic stenosis group, 9% of the pulmonary stenosis group, and 4% of the control group. Seven of 60 (12%) patients had laboratory findings that implied a diagnosis of AVWS, and two of these (28%) had a history of bleeding. The frequency of AVWS was 14% in patients with aortic stenosis and 9% in those with pulmonary stenosis. Conclusion: AVWS is not rare in stenotic obstructive cardiac diseases. A detailed history of bleeding should be taken from patients with valvular disease. Even if the history is negative, whole blood count, PT and aPTT should be performed. If necessary, PFA-100 closure time and further tests should be planned for the diagnosis of AVWS. PMID:27841910

    Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease characterized with symptoms related to esophageal dysfunction and eosinophil-predominant inflammation. There has been a dramatic increase in the diagnosis of this disease in recent years. The primary objective of this study was to determine the frequency of EoE in adult patients who were evaluated by gastroenterologists in our clinic with esophageal symptoms. Between November 2010 and May 2011, 311 adult patients who were evaluated in our clinic with esophageal symptoms were enrolled prospectively. All patients underwent endoscopy and had biopsies taken. Gastroesophageal reflux disease was excluded by either proton pump inhibitory treatment or 24-hour ambulatory pH monitorization. The diagnosis was confirmed by one independent pathologist. Frequency of EoE in patients with esophageal symptoms was 2.6% (n = 8; four men and four women). Mean age at diagnosis was 40.2 ± 8 years. Heartburn was the predominant symptom in patients (75% of the patients), and 87.5% (n = 7) of patients had more than one symptom at diagnosis. Nearly 38% of the patients (n = 3) had a history of allergic disease. Endoscopic findings were as follows: transient/fixed esophageal rings (25%), white exudates (25%), and normal appearance (50%). Median number of circulating eosinophils was 208 (93-659)/mm(3) . Median number of intraepithelial eosinophils in proximal-middle 1/3 part and distal 1/3 part of esophagus were 0 (0-50)/hpf and 37 (16-50)/hpf, respectively. In conclusion, EoE is not rare in Turkey, and it should be considered in the differential diagnosis of patients with esophageal symptoms.

To the authors' knowledge, there have been no reports of adults with amyoplasia in the current literature. We report a case of an adult patient with cervical stenosis in the setting of amyoplasia. Patients and Methods A 48-year-old patient with amyoplasia and over 30 previous orthopedic reconstructive surgeries presented with neck pain radiating down his left shoulder and into the fingers, dysesthesia in his fingertips, and left-sided periauricular headache. A diagnosis of central spinal canal stenosis and bilateral foraminal stenosis at C3–C7 with radiculopathy was made based on computed tomography scans. Because of a prior right-side sternocleidomastoid muscle transfer, a left-side C3–C4, C5–C7 anterior cervical discectomy and fusion procedure was performed. Results The patient experienced significant improvement in symptoms that was transient. Symptoms returned to preoperative values after 1 year, despite significant and persistent improvement in stenosis. Conclusions Both amyoplasia and cervical stenosis can manifest in neurologic symptoms. Distinguishing the causing pathology can be challenging. The radiographic improvement of cervical stenosis in a patient with amyoplasia is not always associated with long-standing pain relief. PMID:24715873

    2005-01-01

    The most common type of esophageal dysfunction associated with chest pain is gastroesophageal reflux, which may be induced by exercise. The effect of exercise on esophageal function has mainly been investigated in normal subjects or trained athletes. Few studies have investigated exercise and esophageal motility disorders. One hundred and thirty-five patients underwent ambulatory esophageal manometry and pH monitoring, before, during and immediately after moderate exercise. Patients were divided into four groups: Normal, nutcracker, diffuse spasm and gastroesophageal reflux disease (GERD). Ambulatory manometry and pH were monitored while exercising on a treadmill during which standardized boluses of water were administered. Nutcracker and diffuse spasm patients demonstrated a significant fall in esophageal wave amplitude during exercise compared to controls, which returned rapidly to pre exercise values after resting. There was no evidence of acid reflux in the non-reflux groups during exercise. Reflux was noted in 13 patients with GERD during exercise, none of whom had evidence of reflux at the onset of exercise. When these patients were classified by reflux type, the majority, 11 patients, were found to come from the combined or supine reflux group. Esophageal amplitude in nutcracker esophagus does not increase during moderate exercise. Moderate exercise provokes reflux in GERD patients with combined or supine reflux.

    This paper reviews current concepts and results in the management of congenital tracheal stenosis (CTS). Diagnostic options are considered and the requirements for successful management defined. Chief amongst these is a multi-disciplinary approach with individualised patient management. Severe long-segment CTS represents the biggest challenge to clinicians and the worst problems for affected families. Near-death episodes are frequent in affected infants and some cannot be ventilated and require ECMO. Associated cardiovascular anomalies are frequent. Patients require immediate resuscitation and transfer to a specialist unit. After careful assessment, accurate diagnosis and discussion, primary resection and end-to-end repair with a slide technique should always be the first option, with concomitant repair of associated cardiac anomalies. If this is impossible because of the severity of the lesion, some form of patch tracheoplasty will be indicated. Cardiopulmonary bypass is often required. Patches include pericardium, autograft trachea, carotid artery, cartilage, and allograft trachea. Mortality ranges from 0 to 30% in the literature, which largely comprises single-centre long-term experience. Recurrence is common and can be managed by stenting and tracheal homograft implantation. Long-term quality of life of survivors is little reported but seems good. Physiological data are lacking. To improve results, we suggest a treatment algorithm to rationalise care.

    The relative rarity of hypertrophic pyloric stenosis (HPS) in the developing world makes its diagnosis a challenge to many physicians. This study audits the management of HPS at a tertiary hospital in South Africa, with a view to defining its regional pattern. This is a retrospective review of records of all patients (n = 63) managed for HPS over an eight-year period (2002-2010). The mean age at presentation was 6.2 weeks and the male/female ratio was 6:1. The majority of patients presented with non-bilious vomiting. Abdominal ultrasound had a sensitivity of 65% and 81.3% when the criteria of pyloric muscle thickness >4 mm and pyloric channel length >16 mm were used, respectively. The overall complication rate was 14.3% and the mortality rate was 0%. Despite the rarity of HPS in the Third World, the outcome of its management is favourable. However, the sensitivity of abdominal ultrasound for diagnosing HPS is low.

    Does infant malnutrition produce smaller adult spinal canals? Lumbar and thoracic vertebrae (n X 1073), from a prehistoric American Indian population (15-55 yrs of age), were measured for anteroposterior (AP) and transverse (TR) vertebral canal sizes, nerve root tunnel (intervertebral foramen) widths (NRT), vertebral heights (VH), vertebral osteophytosis (VO), and tibial lengths. They underwent a dietary change from hunting-gathering, protein rich (PR), to maize agriculture, protein deficient (PD), between 950 and 1300 A.D. Multivariate analyses controlled for age, sex, culture, NRT, VH, VO, and wedging. Canal size was significantly smaller in the PD. AP diameters were generally and highly correlated with NRT, and thus both spinal stenosis and sciatica may have a developmental basis. Canal size was independent of statural components. Consequently, canal size is a most powerful tool in assessing the presence infant malnutrition. Moreover, perhaps the association between canal size and low-back pain (LBP) found in living populations has been underestimated, and this component of LBP is preventable.

    The aim of this study was to investigate histomorphological and immunophenotypic features in pill-induced esophagitis. We comparatively evaluated the histomorphological, immunophenotypic features of pill-induced esophagitis vs. reflux esophagitis, as well as clinical information and endoscopic findings. Fifty-two tissue pieces from 22 cases of pill-induced esophagitis, 46 pieces from 20 reflux esophagitis, and 16 pieces from 14 control samples were subjected to immunohistochemistry for inflammatory infiltrates (CD3 for T lymphocyte, CD20 for B lymphocyte, CD56 for NK cell, CD68 for macrophage, CD117 for mast cell) and eosinophil chemotaxis-associated proteins (Erk, leptin, leptin receptor, pSTAT3, phospho-mTOR). As a result, Histomorphology showed that a diffuse pattern of dilated intercellular spaces was more frequently observed in pill-induced esophagitis, while reactive atypia and subepithelial papillary elongation were more often found in reflux esophagitis (P < 0.05, respectively). Interestingly, intraepithelial eosinophilic microabscess, intraepithelial pustule and diffuse pattern of dilated intercellular spaces were observed in 14% (3 cases), 9% (2 cases) and 32% (7 cases) of pill-induced esophagitis, respectively, but in no cases of reflux esophagitis. Regarding intraepithelial inflammatory infiltrates in pill-induced esophagitis, T lymphocytes were the most common cells, followed by eosinophil; 11 and 7 in one x400 power field, respectively. Intraepithelial pSTAT3-positive pattern was more frequently observed in pill-induced esophagitis than in reflux esophagitis, at 45% (10 cases) versus 10% (2 cases), respectively (P < 0.05). Considering the distal esophageal lesion only, intraepithelial pustule, diffuse dilated intercellular spaces and stromal macrophages were more frequently found in distal pill-induced esophagitis, whereas reactive atypia and intraepithelial mast cells in reflux esophagitis (P < 0.05, respectively).

    The esophagus serves to transport food and fluid from the pharynx to the stomach. Manometry has been the “golden standard” for the diagnosis of esophageal motility diseases for many decades. Hence, esophageal function is normally evaluated by means of manometry even though it reflects the squeeze force (force in radial direction) whereas the bolus moves along the length of esophagus in a distal direction. Force measurements in the longitudinal (axial) direction provide a more direct measure of esophageal transport function. The technique used to record axial force has developed from external force transducers over in-vivo strain gauges of various sizes to electrical impedance based measurements. The amplitude and duration of the axial force has been shown to be as reliable as manometry. Normal, as well as abnormal, manometric recordings occur with normal bolus transit, which have been documented using imaging modalities such as radiography and scintigraphy. This inconsistency using manometry has also been documented by axial force recordings. This underlines the lack of information when diagnostics are based on manometry alone. Increasing the volume of a bag mounted on a probe with combined axial force and manometry recordings showed that axial force amplitude increased by 130% in contrast to an increase of 30% using manometry. Using axial force in combination with manometry provides a more complete picture of esophageal motility, and the current paper outlines the advantages of using this method. PMID:19132762

    Abstract Background: Human papillomavirus (HPV) has been identified to be related to progression of esophageal cancer. However, the results remain controversial. A meta-analysis of epidemiologic studies was therefore conducted to address this issue. Methods: The electronic databases of MEDLINE and Excerpta Medica database were searched till April 30, 2016. Study-specific risk estimates were pooled using a random-effects model. Results: Ten studies involving a total of 1184 esophageal cancer cases were included in this meta-analysis. The pooled hazard ratio comparing HPV-positive to HPV-negative esophageal cancers was 1.03 (95% confidence interval 0.78–1.37), which was not significantly correlated with improved survival. However, HPV-16-positive patients might have a significantly favorable survival (hazard ratio 0.73, 95% confidence interval 0.44–1.21). Conclusion: The meta-analysis indicated that HPV infection may not be of prognostic utility in the evaluation of factors contributing to esophageal cancer. Further large prospective studies are encouraged to stratify survival analysis by HPV type. PMID:27861358

    The high incidence of dysphagia in patients with symptomatic gastroesophageal reflux (GER) but no evidence of peptic stricture suggests esophageal motor dysfunction. Conventional methods for detecting dysfunction (radiologic and manometric examinations) often fail to detect abnormality in these patients. Radionuclide transit (RT), a new method for detecting esophageal motor dysfunction, was used to prospectively assess function in 29 patients with symptomatic GER uncomplicated by stricture before and three months after antireflux surgery (HILL). The preoperative incidence of dysphagia and esophageal dysfunction was 73% and 52%, respectively. During operation (Hill repair), intraoperative measurement of the lower esophageal sphincter pressure was performed and the LESP raised to levels between 45 and 55 mmHg. The preoperative lower esophageal sphincter pressure was raised from a mean of 8.6 mmHg, to mean of 18.5 mmHg after operation. No patient has free reflux after operation. Postoperative studies on 20 patients demonstrated persistence of all preoperative esophageal dysfunction despite loss of dysphagia. RT has demonstrated a disorder of esophageal motor function in 52% of patients with symptomatic GER that may be responsible for impaired esophageal clearance. This abnormality is not contraindication to surgery. The results indicate that construction of an effective barrier to reflex corrects symptoms of reflux, even in the presence of impaired esophageal transit. Radionuclide transit is a safe noninvasive test for assessment of esophageal function.

    Abstract Clinicopathologic features and clinical outcomes of gastrointestinal stromal tumors (GISTs) in esophagus are limited, because of the relatively rare incidence of esophageal GISTs. Therefore, the aim of the current study was to investigate the clinicopathologic features and clinical outcomes of esophageal GISTs, and to investigate the potential factors that may predict prognosis. Esophageal GIST cases were obtained from our center and from case reports and clinical studies extracted from MEDLINE. Clinicopathologic features and survivals were analyzed and compared with gastric GISTs from our center. The most common location was lower esophagus (86.84%), followed by middle and upper esophagus (11.40% and 1.76%). The majority of esophageal GISTs were classified as high-risk category (70.83%). Mitotic index was correlated with histologic type, mutational status, and tumor size. The 5-year disease-free survival and disease-specific survival were 65.1% and 65.9%, respectively. Tumor size, mitotic index, and National Institutes of Health risk classification were associated with prognosis of esophageal GISTs. Only tumor size, however, was the independent risk factor for the prognosis of esophageal GISTs. In comparison to gastric GISTs, the distribution of tumor size, histologic type, and National Institutes of Health risk classification were significantly different between esophageal GISTs and gastric GISTs. The disease-free survival and disease-specific survival of esophageal GISTs were significantly lower than that of gastric GISTs. The most common location for esophageal GISTs was lower esophagus, and most of the esophageal GISTs are high-risk category. Tumor size was the independent risk factor for the prognosis of esophageal GISTs. Esophageal GISTs differ significantly from gastric GISTs in respect to clinicopathologic features. The prognosis of esophageal GISTs was worse than that of gastric GISTs. PMID:26765432

    Nonspecific esophageal motility disorder (NEMD) is a vague category used to include patients with poorly defined esophageal contraction abnormalities. The criteria include "ineffective" contraction waves, ie, peristaltic waves that are either of low amplitude or are not transmitted. The aim of this study was to identify the prevalence of ineffective esophageal motility (IEM) found during manometry testing and to evaluate esophageal acid exposure and esophageal acid clearance (EAC) in patients with IEM compared to those with other motility findings. We analyzed esophageal manometric tracings from 600 consecutive patients undergoing manometry in our laboratory following a specific protocol from April 1992 through October 1994 to identify the frequency of ineffective contractions and the percentages of other motility abnormalities present in patients meeting criteria for NEMD. Comparison of acid exposure and EAC was made with 150 patients who also had both esophageal manometry and pH-metry over the same time period. Sixty-one of 600 patients (10%) met the diagnostic criteria for NEMD. Sixty of 61 (98%) of these patients had IEM, defined by at least 30% ineffective contractions out of 10 wet swallows. Thirty-five of these patients also underwent ambulatory esophageal pH monitoring. Patients with IEM demonstrated significant increases in both recumbent median percentage of time of pH <4 (4.5%) and median distal EAC (4.2 min/episode) compared to those with normal motility (0.2%, 1 min/episode), diffuse esophageal spasm (0%, 0.6 min/episode), hypertensive LES (0%, 1.8 min/episode), and nutcracker esophagus (0.4% 1.6 min/episode). Recumbent acid exposure in IEM did not differ significantly from that in patients with systemic scleroderma (SSc) for either variable (5.4%, 4.2 min/episode). We propose that IEM is a more appropriate term and should replace NEMD, giving it a more specific manometric identity. IEM patients demonstrate a distinctive recumbent reflux pattern

    Background Esophageal cancer (EC) is the eighth most prevalent malignant tumor and the sixth leading cause of cancer mortality throughout the world. Despite the technical developments in diagnosis and treatment, the 5-year survival rate is still low. The etiology of EC remains poorly understood; multiple risk factors may be involved and account for the great variation in EC incidence in different geographic regions. Summary Infection with carcinogenetic pathogens has been proposed as a risk factor for EC. This review explores the recent studies on the association of human papillomavirus (HPV), Epstein-Barr virus (EBV), Helicobacter pylori and esophageal bacterial biota with EC. Key Message Among the above-mentioned pathogens, HPV most likely contributes to esophageal squamous cell carcinoma (ESCC) in high-risk populations. New techniques are being applied to studies on the role of infection in EC, which will inevitably bring novel ideas to the field in the near future. Practical Implications Multiple meta-analyses support the finding of a higher HPV detection rate in regions associated with high risk for ESCC compared to low-risk areas. A potential role of HPV in the rise of esophageal adenocarcinoma (EAC) was proposed recently. However, further studies are required before a firm conclusion can be drawn. Less work has been done in studying the association between EBV and ESCC, and the results are quite controversial. H. pylori infection is found to be inversely related to EC, which is probably due to the reduced incidence of gastroesophageal reflux disease. Analysis of the esophageal bacterial biota revealed distinct clusters of bacteria in normal and diseased esophagi. A type II microbiome rich in Gram-negative bacteria potentially contributes to EAC by inducing chronic inflammation. Novel findings from such studies as these may benefit public health by justifying anti-infection measures to prevent EC. PMID:26674173

    Introduction: Carotid endarterectomy (CEA) is a standard treatment for the prevention of stroke and death in patients with significant stenosis of the internal carotid artery. Eversion endarterectomy is warranted in patients with symptoms of cerebral ischemia and the degree of stenosis of 70-99%. The same is suitable for treating a symptomatic carotid artery stenosis with contralateral stenosis (50-70%). Purpose: The aim of this study was to evaluate perioperative complications (ICV, TIA, MI, mortality) in patients treated with carotid eversion endarterectomy with unilateral and bilateral symptomatic stenosis (with bilateral stenosis treated with ACI stenosis ≥70%). Patients and Methods: The study included 139 patients with symptomatic carotid artery stenosis at the Department of Vascular Surgery of the University Clinical Center of Sarajevo in the period from January 2012 to December 2014 year. Given the involvement of ACI stenosis patients were divided into two groups. Group A consisted of 74 patients with bilateral stenosis (surgically treated with ACI stenosis ≥70%, while the degree of stenosis opposite ACI was from 50-70%), and group B of 65 patients with unilateral stenosis ≥70%. Results: Of the 139 patients included in the study, in the group A was 74, of which 46 male (62.2%) and 28 female (37.8%), while in group B were 42 male (64.6%) and 23 female (35.4%) (p = 0.90). The subjects in group A were slightly older 65.9 (± 7.8) compared to group B 64.2 (± 7.7) (p = 0.17). Analysis of risk factors indicating a higher number in Group A compared to group B, but the difference was not statistically significant: 34 smokers (45.9%) versus 36 (55.4%); p = 0:34), patients with hypertension (63 (85.1%) against the 52 (80.0%); p = 0.56), with statin therapy (62 (83.8%) versus 52 (80.0%); p = 0.72), diabetes (18 (24.3%) versus 18 (27.7%); p = 0.79) and with a heart disease (18 (24.3%) versus 7 (10.8%); p = 0.06).

    The treatment of carotid stenosis entails three methodologies, namely, medical management, carotid angioplasty and stenting (CAS), as well as carotid endarterectomy (CEA). The North American Symptomatic Carotid Endarterectomy Trial (NASCET) and European Carotid Surgery Trial (ECST) have shown that symptomatic carotid stenosis greater than 70% is best treated with CEA. In asymptomatic patients with carotid stenosis greater than 60%, CEA was more beneficial than treatment with aspirin alone according to the Asymptomatic Carotid Atherosclerosis (ACAS) and Asymptomatic Carotid Stenosis Trial (ACST) trials. When CAS is compared with CEA, the CREST resulted in similar rates of ipsilateral stroke and death rates regardless of symptoms. However, CAS not only increased adverse effects in women, it also amplified stroke rates and death in elderly patients compared with CEA. CAS can maximize its utility in treating focal restenosis after CEA and patients with overwhelming cardiac risk or prior neck irradiation. When performing CEA, using a patch was equated to a more durable result than primary closure, whereas eversion technique is a new methodology deserving a spotlight. Comparing the three major treatment strategies of carotid stenosis has intrinsic drawbacks, as most trials are outdated and they vary in their premises, definitions, and study designs. With the newly codified best medical management including antiplatelet therapies with aspirin and clopidogrel, statin, antihypertensive agents, strict diabetes control, smoking cessation, and life style change, the current trials may demonstrate that asymptomatic carotid stenosis is best treated with best medical therapy. The ongoing trials will illuminate and reshape the treatment paradigm for symptomatic and asymptomatic carotid stenosis. PMID:26417191

    Background Eosinophilic esophagitis (EE) is an emerging worldwide disease that mimics gastroesophageal reflux disease. Objective Early studies have suggested that esophageal eosinophilia occurs in association with T helper type 2 allergic responses, yet the local and systemic expression of relevant cytokines has not been well characterized. Methods A human inflammatory cytokine and receptor PCR array containing 84 genes followed by PCR validation and multiplex arrays were used to quantify cytokine mRNA in esophageal biopsies and blood levels. Results Esophageal transcripts of numerous chemokines [e.g. CCL1, CCL23, CCL26 (eotaxin-3), CXCL1, and CXCL2], cytokines (e.g. IL13 and ABCF1), and cytokine receptors (e.g. IL5RA) were induced at least 4-fold in individuals with EE. Analysis of esophageal biopsies (n=288) revealed that eotaxin-3 mRNA level alone had 89% sensitivity for distinguishing EE from non-EE individuals. The presence of allergy was associated with significantly increased esophageal expression of IL4 and IL5 mRNA in active EE patients. We identified 8 cytokines (IL-4, IL-13, IL-5, IL-6, IL-12p70, CD40L, IL-1α, and IL-17) whose blood levels retrospectively distinguished 12 non-EE from 13 EE patients with 100% specificity and 100% sensitivity. When applied to a blinded, prospectively recruited group of 36 patients, the cytokine panel scoring system had a 79% positive predictive value, 68% negative predictive value, 61% sensitivity, and 83% specificity for identifying EE. Conclusion Evidence is presented that IL13 and IL5 associate with eosinophil and eotaxin-3 levels, indicating the key role of adaptive Th2 immunity in regulating eotaxin-3-driven esophageal eosinophilia in the absence of a consistent systemic change in cytokines.

    AIM: To determine if esophageal capsule endoscopy (ECE) is an adequate diagnostic alternative to esophagogastroduodenoscopy (EGD) in pre-bariatric surgery patients. METHODS: We conducted a prospective pilot study to assess the diagnostic accuracy of ECE (PillCam ESO2, Given Imaging) vs conventional EGD in pre-bariatric surgery patients. Patients who were scheduled for bariatric surgery and referred for pre-operative EGD were prospectively enrolled. All patients underwent ECE followed by standard EGD. Two experienced gastroenterologists blinded to the patient’s history and the findings of the EGD reviewed the ECE and documented their findings. The gold standard was the findings on EGD. RESULTS: Ten patients with an average body mass index of 50 kg/m2 were enrolled and completed the study. ECE identified 11 of 14 (79%) positive esophageal/gastroesophageal junction (GEJ) findings and 14 of 17 (82%) combined esophageal and gastric findings identified on EGD. Fisher’s exact test was used to compare the findings and no significant difference was found between ECE and EGD (P = 0.64 for esophageal/GEJ and P = 0.66 for combined esophageal and gastric findings respectively). Of the positive esophageal/GEJ findings, ECE failed to identify the following: hiatal hernia in two patients, mild esophagitis in two patients, and mild Schatzki ring in two patients. ECE was able to identify the entire esophagus in 100%, gastric cardia in 0%, gastric body in 100%, gastric antrum in 70%, pylorus in 60%, and duodenum in 0%. CONCLUSION: There were no significant differences in the likelihood of identifying a positive finding using ECE compared with EGD in preoperative evaluation of bariatric patients. PMID:24115815

    The incidence of eosinophilic esophagitis (EoE) has increased in the past several years, yet our understanding of its pathogenesis remains limited. To test the hypothesis that microRNAs (miRNAs) are altered in children with EoE, miRNAs were profiled in esophageal mucosa biopsies obtained from patients with active disease (n = 5) and healthy control subjects (n = 6). Fourteen miRNAs were significantly altered between groups; four of these miRNAs were decreased in EoE patients. A panel of five miRNAs (miR-203, miR-375, miR-21, miR-223, and miR-142-3p) were selected for validation in an independent set of samples from control (n = 22), active disease (n = 22), inactive disease (n = 22), and gastroesophageal reflux disease (n = 6) patients. Each panel miRNA was significantly altered among groups. miRNA changes in esophageal biopsies were not reflected in the circulating RNA pool, as no differences in panel miRNA levels were observed in sera collected from the four patient groups. In addition, in contrast to previous studies, no change in esophageal miRNA levels was detected following treatment that resolved esophageal eosinophilia. In an effort to identify the ramifications of reduced esophageal miR-203, miR-203 activity was inhibited in cultured epithelial cells via expression of a tough decoy miRNA inhibitor. Luciferase reporter assays demonstrated that miR-203 does not directly regulate human IL-15 through targeting of the IL-15 3'-untranslated region. From these experiments, it is concluded that miRNAs are perturbed in the esophageal mucosa, but not the serum, of pediatric EoE patients. Further investigation is required to decipher pathologically relevant consequences of miRNA perturbation in this context.

    The management of asymptomatic carotid stenosis remains unclear in terms of screening as well as of treatment. The degree of carotid stenosis is not enough to clarify the debate. It seems useful to search among severe carotid stenosis parameters indicating higher ipsilateral stroke risk. Duplex ultrasound and transcranial Doppler offer this opportunity with a diagnostic battery allowing to evaluate hemodynamical risk (degree of stenosis, common carotid flow, MCA signal, cerebral vasoreactivity), thrombo-embolic risk (echostructure of the stenosis, micro-embolic signals, HITS) and progression of the stenosis.

    Technetium-99m albumin-sucralfate ((/sup 99m/Tc)Su) can be used to demonstrate peptic ulcer disease in man and animals. We evaluated the usefulness of (/sup 99m/Tc)Su for detecting various grades of esophagitis. (/sup 99m/Tc)Su adhered to the distal esophagus for up to 3 hr in five of six patients with esophageal ulcers but adhered to only two of nine with lesser degrees of esophagitis. No adherence was seen in five patients without esophagitis. Thus, (/sup 99m/Tc)Su may not be useful for detecting any but the most severe grade of esophagitis. Based on these results, we speculate that the previously documented beneficial effects of sucralfate on mild to moderate esophagitis may be due to other mechanisms besides adherence to the ulcerated mucosa.

    Symptomatic adjacent segment disease (ASD) after anterior cervical fusion (ACF) is reported in 25% of patients at 10 years postoperatively. Debate continues as to whether this degeneration is due to the natural history of the disk or the changed biomechanics after ACF. This study explored whether congenital stenosis predisposes patients to an increased incidence of ASD after ACF. A retrospective review of 635 patients with myelopathy or radiculopathy was performed; 364 patients had complete records for review. Patients underwent 1- to 5-level ACF (94 one-level, 145 two-level, 79 three-level, 45 four-level, and 1 five-level). Radiographs were evaluated for bony congenital stenosis using validated parameters, and ASD was measured according to Hilibrand's criteria and correlated with symptomatic ASD. Congenital stenosis was found in 21.7% of patients and radiographic ASD in 33.5%, with a significant association between these parameters. However, symptomatic ASD occurred in 11.8% of patients; no association between congenital stenosis and symptomatic ASD or myelopathy and ASD was found. Clinical results demonstrated excellent or good Robinson scores in 86.2% of patients and Odom scores in 87% of patients. Despite mostly excellent to good outcomes, symptomatic ASD is common after ACF. Although congenital stenosis appears to increase the incidence of radiographic ASD, it does not appear to predict symptomatic ASD.

    2015-01-01

    Degeneration of the intervertebral disc results in initial relative instability, hypermobility, and hypertrophy of the facet joints, particularly at the superior articular process. This finally leads to a reduction of the spinal canal dimensions and compression of the neural elements, which can result in neurogenic intermittent claudication caused by venous congestion and arterial hypertension around nerve roots. Most patients with symptomatic lumbar stenosis had neurogenic intermittent claudication with the risk of a fall. However, although the physical findings and clinical symptoms in lumbar stenosis are not acute, the radiographic findings are comparatively severe. Magnetic resonance imaging is a noninvasive and good method for evaluation of lumbar stenosis. Though there are very few studies pertaining to the natural progression of lumbar spinal stenosis, symptoms of spinal stenosis usually respond favorably to non-operative management. In patients who fail to respond to non-operative management, surgical treatments such as decompression or decompression with spinal fusion are required. Restoration of a normal pelvic tilt after lumbar fusion correlates to a good clinical outcome. PMID:26435805

    Introduction The dominant location of electrical triggers for initiating atrial fibrillation (AF) originates from the muscle sleeves inside pulmonary veins (PVs). Currently, radiofrequency ablation (RFA) is performed outside of the PVs to isolate, rather than directly ablate these tissues, due to the risk of intraluminal PV stenosis. Methods In 4 chronic canine experiments, we performed direct PV muscle sleeve RFA ± post-ablation drug-coated balloon (DCB) treatment with paclitaxel/everolimus. Of the 4 PVs, 2 PVs were ablated and treated with DCB, 1 PV was ablated without DCB treatment (positive control), and 1 PV was left as a negative control. Local electrograms were assessed in PVs for near-field signals and were targeted for ablation. After 12-14 weeks survival, PVs were interrogated for absence of near-field PV potentials, and each PV was assessed for stenosis. Results All canines survived the study period without cardiorespiratory complications, and remained ambulatory. In all canines, PVs that were ablated and treated with DCB remained without any significant intraluminal stenosis. In contrast, PVs that were ablated and not treated with DCB showed near or complete intraluminal stenosis. At terminal study, PV potentials remained undetectable. A blinded, histologic analysis demonstrated that ablated PVs without DCB treatment had extensive thrombus, fibrin, mineralization, and elastin disruption. Conclusion Our chronic canine data suggest that direct PV tissue ablation without subsequent stenosis is feasible with the use of post-ablation DCBs. PMID:26075706

    2012-01-01

    Background Congenital nasal pyriform aperture stenosis is a rare and potentially lethal form of airway obstruction in newborns. Immediate recognition and appropriate therapy are mandatory for this potentially life-threating condition. This anomaly may present as an isolated malformation or may be associated with other cranial-facial anomalies. Clinically, CNPS shows unspecific symptoms of nasal airway obstruction such as apnoic crisis, episodic cyanosis and inability to nurse. The purpose of this report is to present author's experience in the surgical management of this rare pathology in 3 patients. Patients and Methods Three cases of congenital nasal pyriform aperture stenosis were reviewed for presentation of the disorder, management and effectiveness of the surgical treatment. Results All the patients underwent a surgical correction of the pyriform aperture stenosis using a sublabial approach followed by nasal stenting. During the follow-up no cases of restenosis, respiratory failure or cyanosis were detected. Conclusions Congenital pyriform aperture stenosis should be suspected in newborns with clinical signs of severe nasal obstruction associated with a difficulty to pass a small catheter though the anterior nasal valve. Timely recognition is mandatory to prevent a potential deadly outcome. Surgical correction of the stenosis though a sublabial approach followed by a nasal stenting revealed to be most effective treatment for these patients. PMID:22731387

    Purpose The purpose of this study is to accurately characterize the cephalic arch segments into four domains and to enable more specific evaluation of cephalic arch stenosis (CAS) and determine the frequency of stenosis in each domain. Methods After Institutional Review Board (IRB) approval, a retrospective chart review was done to define a population of patients receiving hemodialysis who developed CAS as apparent on clinically indicated radiologic imaging. A standardized approach was devised to categorize four domains of the cephalic arch. Domain I was defined as the peripheral portion of the arch and Domain IV was the distal portion of the cephalic vein near termination with the axillary vein. The magnitude of stenosis as measured by percentage was determined and compared in the four domains. Results The most frequent location for stenosis was found in domain IV when compared with domains II or I (p<0.01). The magnitude of stenosis differed across all domains (p<0.001) with the least common place for CAS in domain I. Treatment of CAS included angioplasty in all, thrombectomy in eight, and stent placement in five. Conclusions CAS occurs most commonly in the terminal portion of the arch. Four standardized domains have been defined; future work will validate these findings and determine the best intervention for each domain. PMID:25198819

    Sunitinib is a chemotherapeutic agent that has been approved for renal cell carcinoma and gastrointestinal stromal tumors resistant to imatinib. It is usually well tolerated and severe gastrointestinal side effects are rare. There are very few reports of sunitinib causing severe esophagitis, and only one of them was previously reported as exfoliative esophagitis. We describe a case of severe sunitinib-induced exfoliative esophagitis that resulted in overt gastrointestinal bleed. PMID:27921054

    Esophageal cancer represents one of the most aggressive digestive tumors, with a survival rate at 5 years of only 10%. Globally, during the last three decades, there has been an increasing incidence of the esophageal cancer, approx. 400,000 new esophageal cancers being currently diagnosed annually. This represents the eighth leading cause of cancer incidence and the sixth leading cause of cancer death overall. Taking into account the population’s global aging and thus, the increase in the number of patients who will not bear surgery, PCT and radiation, or the fact that they do not want it especially because of deficiencies and associated pathology, the endoscopic ablative techniques with palliation purposes represent the alternative. If we refer to the Western Europe countries and North America, we notice an increase of esophageal adenocarcinoma rate versus squamous cancer. As for the Asian region, referring in particular to China and Japan, 9 out of 10 esophageal cancers are squamous cell carcinomas. For at least half of the patients with EC (esophageal cancer) there is no hope of healing because of the advanced regional malignant invasion (T3-4, N+, M+) with no chemo and radiotherapy response, poor preoperative patients’ conditions or systemic metastasis. The low life expectancy does not justify the risky medical procedures, the goal of the therapy consisting in the improvement of the quality of life by eliminating dysphagia (reestablishing oral feeding) which represents the most common complication of EC, the respiratory tract complication caused by eso-tracheal fistulas or by eliminating chest pain. To treat dysphagia, which is the main target of palliation, combined methods like endoscopic, chemo and radio-therapy, can be used, each one with indications, benefits and risks.

    Fifteen consecutive patients presenting with dysphagia due to aluminum phosphide (AP)-induced esophageal strictures were studied retrospectively to elucidate the natural history of AP-induced esophageal strictures and to evaluate the efficacy of bougie dilation. The median time lag between consumption of AP and occurrence of dysphagia was 3 weeks. All patients had a single stricture and could be dilated using a bougie dilator. Thirteen patients were relieved of dysphagia on a mean (SD) follow-up of 18 (7.3) months. Two patients had recalcitrant strictures and needed needle-knife incision of the stricture followed by balloon dilation. The strictures opened up well in both the patients and they were relieved of dysphagia. AP-induced esophageal stricture is a new cause of benign esophageal stricture. Most patients present with dysphagia around 3 weeks after consumption of AP tablets. A single esophageal stricture is found in these patients. Most strictures respond very well to bougie dilation. However, some of the strictures may be recalcitrant and may require needle-knife incision and balloon dilation.

    The value of gastroesophageal (G/E) scintigraphy in the diagnosis of gastroesophageal reflux was assessed in 51 subjects, who presented with heartburn and had endoscopic evidence of reflux esophagitis. G/E scintigraphy was done using /sup 99m/Tc sulfur-colloid in acidified orange juice. The G/E reflux index was calculated according to previous reports. The mean (+/- SD) G/E reflux index in 18 patients with severe esophagitis and 30 patients with moderate esophagitis were 1.6% (+/- 1.5) and 3.2% (+/- 5.0), respectively. The mean G/E reflux index in 14 control subjects was 2.4% (+/- 1.1). There was no significant difference between the esophagitis and control groups. Furthermore, if 4% was taken as upper limit of normal, this will include almost all the esophagitis patients and controls. It is concluded that the G/E reflux index based on G/E scintigraphy is of little value in the diagnosis of G/E reflux.

    Esophagic Intramural Hematoma is an uncommon clinical condition, with a prognosis which is essentially benign. On most cases, a predisposing or precipitating factor may be seen, with the most common ones being the history of esophagic instrumentation, food impactations and thrombocytopenia. In the following manuscript, the authors present the case of a 54-years-old male with history of valve replacement surgery, who was treated at the Clinica Cardiovascular (Medellin, Colombia), with a clinical case of Intramural Esophagic Hematoma that was later confirmed to be due to a Coumarinic overanticoagulation. On this case, it is evidenced that Intramural Esophagic Hematoma is an unrecognized complication of Courmarinic anticoagulation therapy. PMID:20069068

    2015-08-01

    Dysphagia or swallowing disorder is very common (range, 15-52%) in patients with esophageal atresia. Children present with a wide range of symptoms. The most common diagnostic tools to evaluate esophageal dysphagia, such as upper barium study and manometry, aim to characterize anatomy and function of the esophageal body and the esophagogastric junction (EGJ). Using these technologies, a variety of pathological motor patterns have been identified in children with esophageal atresia. However, the most challenging part of diagnosing patients with esophageal dysphagia lies in the fact that these methods fail to link functional symptoms such as dysphagia with the esophageal motor disorders observed. A recent method, called pressure-flow analysis (PFA), uses simultaneously acquired impedance and manometry measurements, and applies an integrated analysis of these recordings to derive quantitative pressure-flow metrics. These pressure-flow metrics allow detection of the interplay between bolus flow, motor patterns, and symptomatology by combining data on bolus transit and bolus flow resistance. Based on a dichotomous categorization, flow resistance at the EGJ and ineffective esophageal bolus transit can be determined. This method has the potential to guide therapeutic decisions for esophageal dysmotility in pediatric patients with esophageal atresia.

    We carried out a detailed analysis of rat model of esophageal achalasia previously developed by us. Manifest morphological and functional disorders were observed in experimental achalasia: hyperplasia of the squamous epithelium, reduced number of nerve fibers, excessive growth of fibrous connective tissue in the esophageal wall, high contractile activity of the lower esophageal sphincter, and reduced motility of the longitudinal muscle layer. Changes in rat esophagus observed in experimental achalasia largely correlate with those in esophageal achalasia in humans. Hence, our experimental model can be used for the development of new methods of disease treatment.

    Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone) with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT) with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation. PMID:26977330

    The spiral component of blood flow has both beneficial and detrimental effects in human circulatory system. A numerical investigation is carried out to analyze the effect of spiral blood flow through an axisymmetric three dimensional artery having 75% stenosis at the center. Blood is assumed as a Non-Newtonian fluid. Standard k-ω model is used for the simulation with the Reynolds number of 1000. A parabolic velocity profile with spiral flow is used as inlet boundary condition. The peak values of all velocity components are found just after stenosis. But total pressure gradually decreases at downstream. Spiral flow of blood has significant effects on tangential component of velocity. However, the effect is mild for radial and axial velocity components. The peak value of wall shear stress is at the stenosis zone and decreases rapidly in downstream. The effect of spiral flow is significant for turbulent kinetic energy. Detailed investigation and relevant pathological issues are delineated throughout the paper.

    The authors report their surgical experience of complicated stenosis of urethra in the Department of Urology of the Central Hospital of N'Djaména (Tchad) from 1984 to 1987 (July). The surgical treatment was indicated for the complicated cases of stenosis of the urethra, which were obstructed (less than a quarter of the patients who were admitted for urethra stenosis). Before 1984 the only surgical procedure was called "Chemin de fer: a blind pull-through method with a lot of complications. After 1984 the one stage urethroplasties were used in forty four cases: either with a free full thickness skin graft (DEVINE), or with a vascularized flap (BLANDY'S or ORANDI'S technique). The results are studied with a follow up of 18 months. The urethroplasties with a vascularized flap have had less failures (16%) than with a free full thickness skin graft (33%).

    Internal carotid artery (ICA) stenosis may lead to a wide range of clinical symptoms. We describe the case of a 66-year-old female who experienced a transient ischemic attack (TIA) with episodes of limb shaking caused by ICA stenosis. After epilepsy had been suspected and ruled out, studies of her left ICA showed extensive blockage as a result of atherosclerosis. Magnetic resonance angiography (MRA) revealed total occlusion of the left ICA and the patient was eventually medically managed due to the strong possibility of surgical complications. We reported this patient's clinical course to shed light on a rare manifestation of carotid stenosis that may be confused with other diagnoses if not closely scrutinized. PMID:27840754

    We present a case of complete vaginal stenosis in a woman diagnosed with Sheehan's syndrome. The patient delivered at full-term 5 months prior, and experienced massive postpartum bleeding at that time. During evaluation of persistent amenorrhea, we found that her vaginal orifice was completely adhesive and obstructed. Prior to corrective surgery, we managed the patient with an oral contraceptive to induce uterine bleeding into the vaginal outflow tract. After three cycles of an oral contraceptive, we could confirm that there was no stenotic lesion in the vaginal cavity as a hematocolpos was created. Adhesiolysis with scar revision for the vaginal stenosis was successfully performed; it was found that the lesion was limited to only the distal part of the vaginal outlet. Complete vaginal stenosis in reproductive age women with hypopituitarism has not been reported. The artificial induction of hematometrocolpos before surgery was useful in determining the extent of the stenotic lesion, and assured safety.

    Background: Calcific aortic valve stenosis (CAVS) is seen in a large proportion of individuals over 60 years. It is an active process, influenced by lipid accumulation, mechanical stress, inflammation, and abnormal extracellular matrix turnover. Various biomarkers (BMs) are studied, as regards mechanisms, diagnosis and prognosis. Methods: In the calcified valves calcium deposition, elastin fragmentation and disorganization of cellular matrix were assessed, together with expression of OPN, OPG, osteocalcin (OCN) and RL2. We prospectively studied the following serum BMs in 60 patients with CAVS and compared them to 20 healthy controls, free from any cardiac disease: Matrix metalloproteinases (MMP) 2 and 9 and tissue inhibitor of metalloproteinase 1 (TIMP1), which regulate collagen turnover, inflammatory factors, i.e. tumor necrosis factor a (TNFa), interleukin 2 (IL2), transforming growth factor β1 (TGF-β1) which regulates fibrosis, fetuin-A (fet-A), osteopontin (OPN), osteoprotegerin (OPG), sclerostin (SOST), and relaxin-2 (RL2) which positively or negatively regulate calcification. Monocyte chemoattractant protein 1 (MCP-1) which regulates migration and infiltration of monocytes/macrophages was also studied as well as malondialdehyde (MDA) an oxidative marker. Results: Extent of tissue valve calcification (Alizarin Red stain) was negatively correlated with tissue elastin, and RL2, and positively correlated with tissue OCN and serum TIMP1 and MCP-1 and negatively with MMP9. Tissue OCN was positively correlated with OPN and negatively with the elastin. Tissue OPN was negatively correlated with elastin and OPG. Tissue OPN OPG and RL2 were not correlated with serum levels In the serum we found in patients statistically lower TIMP1, fet-A and RL2 levels, while all other BMs were higher compared to the healthy group. Positive correlations between SOST and IL2, OPG and MDA but negative with TNFa and OPN were found; also MMP9 was negatively correlated with TNFa and MCP-1

    Valvular calcification precedes the development of valvular stenosis and may represent an important early phenotype for valvular heart disease. It is known that development of valvular calcification is likely to occur among members of a family. However, the knowledge about the role of genomic predictive markers in valvular calcification is still elusive. Aims of this review are to assess the impact of gene polymorphisms on risk and severity of aortic stenosis and mitral annular calcification. According to the results of the investigations carried out, all polymorphisms may be divided into the three groups conferring the level of evidence of their association with valvular stenosis. It is possible to conclude that apoB (XbaI, rs1042031, and rs6725189), ACE (rs4340), IL10 (rs1800896 and rs1800872), and LPA (rs10455872) gene polymorphisms may be associated with valvular calcific stenosis with a relatively high level of evidence. A number of other polymorphisms, such as PvuII polymorphism within the ORα gene, rs1042636 polymorphism within the CaSR gene, rs3024491, rs3021094, rs1554286, and rs3024498 polymorphisms within the IL10 gene, rs662 polymorphism within the PON1 gene, rs2276288 polymorphism within the MYO7A gene, rs5194 polymorphism within the AGTR1 gene, rs2071307 polymorphism within the ELN gene, rs17659543 and rs13415097 polymorphisms within the IL1F9 gene may correlate with a risk of calcific valve stenosis with moderate level of evidence. Finally, rs1544410 polymorphism within the VDR gene, E2 and E4 alleles within the apoE gene, rs6254 polymorphism within the PTH gene, and rs1800871 polymorphism within the IL10 gene may be associated with aortic stenosis with low level of evidence.

    We examined 11 pediatric patients with eosinophilic esophagitis with a tardy diagnosis. The symptoms were initially thought to be related to other diseases, leading to the use of inadequate therapeutic approaches. The patients were between 3 and 17 years old (mean 7.8 ± 3.8 years), and 8 of the patients were male. Common symptoms included abdominal pain, regurgitation, difficulty in gaining weight, vomiting, dysphagia, and coughing. The mean age for the onset of symptoms was 4.3 ± 2.9 years. Endoscopic findings included normal mucosa in five (45%) patients, thickening of the mucosa with longitudinal grooves in three (27%), erosive esophagitis in two (18%), and a whitish stippling in one (9%) patient. Treatment included the use of a topical corticosteroid for 10 patients. In eight (73%) cases, the treatment made the symptoms disappear. Ten patients underwent histopathological management after treatment, with a decrease in the number of eosinophils. PMID:24106430

    Thoracoscopic approaches for esophageal cancer are still disparate. Complete scopic technique is feasible for esophagectomy. Mini-thoracotomy is effective for excellent exposure of the mediastinum for lymph node dissection. The magnifying effect of a video, by keeping the camera in close proximity to the dissection is essential to perform the same quality of dissection as open surgery. The benefit, for respiratory morbidity, remains to be studied in a large number of patients. Minimizing the chest wall injury contributed, to the reduction of constrictive pulmonary damage. Survival after the thoracoscopic approach was favorably compared with open surgery, when extensive lymphadenectomy was performed. Because the efficacy improves with the surgeon's experience, satisfactory outcome will only be obtained in a center performing a sufficient volume of esophageal surgery to provide the surgeon with opportunities to refine his necessary skills. Improvements in technique and instrumentation should make the procedure more accessible and steepen the learning curve.

    Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus that, in a genetically susceptible host, is triggered by a food antigen. Emerging evidence supports impaired epithelia barrier function as the key initial event in the development of EoE and other allergic diseases. Symptom resolution, histologic remission, and prevention of both disease and treatment-related complications are the goals of treatment. Successful dietary treatments include elemental and elimination diets, both empiric and allergy test directed. These treatments are dietary approaches to inducing clinical and histologic remission. Dietary therapy with an exclusive elemental diet offers the best response with a remission rate of more than 96%. Empiric elimination diets and allergy-directed diets offer similar response with remission induced in 3 of 4 subjects (75%). Cow's milk, wheat, egg and soy are the four common food antigens most likely to induce esophageal inflammation.

    Eosinophilic esophagitis (EoE) is an allergic disorder characterized by infiltration of the esophagus with eosinophils. We had previously reported association of the TSLP/WDR36 locus with EoE. Here we report genome-wide significant associations at four additional loci; c11orf30 and STAT6, which have been previously associated with both atopic and autoimmune disease, and two EoE-specific loci, ANKRD27 that regulates the trafficking of melanogenic enzymes to epidermal melanocytes and CAPN14, that encodes a calpain whose expression is highly enriched in the esophagus. The identification of five EoE loci, not only expands our etiological understanding of the disease but may also represent new therapeutic targets to treat the most debilitating aspect of EoE, esophageal inflammation and remodeling.

    Abstract Introduction: Atrial-esophageal fistula (AEF) is a rare severe disease, which may be associated with radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) or intraoperative radiofrequency ablation of atrial fibrillation (IRAAF). Clinical Findings: We reported a case of a 67-year-old man with AEF following RFCA of AF, who treated with esophageal stenting and surgical repair. Outcomes: He was attacked by out-of-control sepsis and infectious shock after surgery and died. Literature review: We analyzed 57 relevant articles about AEF from 2003 to 2015 by searching PubMed database. According literatures, the most common symptoms were fever, rigor, sepsis, and neurologic symptoms. Chest computer tomography (CT) and contrast enhanced CT may be the reliable noninvasive diagnosis methods because of high sensitive for AEF. Conclusion: Make a definition diagnosis in time with early primary surgical repair may save their lives. Conservative treatment or esophageal stenting alone may not be a better choice for AEF patients. PMID:27787367

    Eosinophilic esophagitis (EoE) is a chronic immune-mediated clinicopathologic disease. The prevalence of EoE is approximately 1/2000 persons, EoE is now the most common cause of food impactions, with healthcare expenditures approaching US$ 1 billion annually. This article will discuss challenges related to proton pump inhibitor responsive esophageal eosinophilia, including distinguishing this condition from EoE and understanding the mechanisms behind the PPI response. For EoE, we will review multiple ongoing debates about treatment and monitoring strategies, including selecting treatment outcomes, optimizing medication formulations, approaching the steroid-refractory patient, conducting dietary elimination, prescribing long-term maintenance therapy and performing esophageal dilation.

    A 65-year-old woman suffered from both chronic gastroesophageal reflux, which was complicated by columnar metaplasia (Barrett's epithelium), and profound hypothyroidism. An esophageal motility tracing showed absence of peristalsis in the lower esophagus and the lower esophageal sphincter (LES) could not be identified. Thyroid replacement therapy, in conjunction with antacid and cimetidine treatment, was associated not only with improvement in the gastroesophageal reflux symptoms, but also with a return of esophageal peristalsis and LES pressure to normal. To support our clinical observations, we rendered four cats hypothyroid with /sup 131/I and documented a fall in LES pressure. We propose that abnormal smooth-muscle function of the esophagus may be another manifestation of the gastrointestinal motility disturbances which are associated with hypothyroidism.

    Treatment approaches for esophageal cancer include primary treatment (surgical or nonsurgical) or adjuvant treatment (preoperative or postoperative). Primary treatments include surgery alone, radiation therapy alone, and radiation therapy plus chemotherapy (combined modality therapy). Adjuvant therapies include preoperative or postoperative radiation therapy, preoperative chemotherapy, and preoperative combined modality therapy. There is considerable controversy as to the ideal therapeutic approach. This review will examine the results of these approaches as well as combined modality therapy using novel regimens.

    EoE is a chronic immune/antigen-mediated clinicopathologic condition that has become an increasingly important cause of upper gastrointestinal morbidity in adults and children over the past 2 decades. It is diagnosed based on symptoms of esophageal dysfunction, the presence of at least 15 eosinophils/high-power field in esophageal biopsies, and exclusion of competing causes of esophageal eosinophilia, including proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE). We review what we have recently learned about the clinical aspects of EoE, discussing the clinical, endoscopic, and histologic features of EoE in adults and children. We explain the current diagnostic criteria and challenges to diagnosis, including the role of gastroesophageal reflux disease and PPI-REE. It is also important to consider the epidemiology of EoE (current incidence of 1/10,000 new cases per year and prevalence of 0.5-1/1,000 cases per year) and disease progression. We review the main treatment approaches and new treatment options; EoE can be treated with topical corticosteroids such as fluticasone and budesonide, or dietary strategies, such as amino acid-based formulas, allergy test-directed elimination diets, and non-directed empiric elimination diets. Endoscopic dilation has also become an important tool for treatment of fibrostenostic complications of EoE. There are number of unresolved issues in EoE, including phenotypes, optimal treatment endpoints, the role of maintenance therapy, and treatment of refractory EoE. The care of patients with EoE and the study of the disease span many disciplines—EoE is ideally managed by a multidisciplinary team of gastroenterologists, allergists, pathologists, and dieticians.

    Forensic implications of esophageal cancer surgery are varied and complex depending on the field of specialization involved i.e. civil law, criminal law, insurance or social security and for the distinct probative requirements related to each field. The aim of this article is to reconstruct the logical procedure of a forensic doctor who actually examines a practical case to establish the profiles of professional responsibility in particular in civil or criminal law.

    We present the case of a 39-year-old man with a severe glottis stenosis. The saddle nose, images of laryngotracheal stenosis and the (FDG) positron-emission tomography/computed tomography lead to a final diagnosis of relapsing polychondritis. In the patient a coexistent myelodysplastic syndrome was diagnosed. Moreover, the elevated total IgG4 exceeding 135 ml/dl requested additional immunochemistry for detection of IgG4-bearing plasma cells in the biopsies. The patient underwent an allogenic stem cell transplantation and died on day 40 after the transplantation because of an acute steroid-resistent graft vs host.

    Salivary gland trauma may result in ductal stenosis and chronic sialadenitis. We describe a case of an 81-year-old woman with a history of intermittent left submandibular swelling that began after recent dental examination and radiographs. Diagnostic sialendoscopy was performed and demonstrated a near complete distal stenosis. It was determined that trauma experienced during dental radiography may have resulted in the patient's ductal obstruction and subsequent sialadenitis. This case illustrates an unusual presentation of non-sialolith-related ductal obstruction in the submandibular gland, treated with sialendoscopic-assisted sialodochoplasty.

    As a minimally invasive treatment of esophageal achalasia per-oral endoscopic myotomy( POEM) was developed in 2008. More than 1,100 cases of achalasia-related diseases received POEM. Success rate of the procedure was more than 95%(Eckerdt score improvement 3 points and more). No serious( Clavian-Dindo classification III b and more) complication was experienced. These results suggest that POEM becomes a standard minimally invasive treatment for achalasia-related diseases. As an off-shoot of POEM submucosal tumor removal through submucosal tunnel (per-oral endoscopic tumor resection:POET) was developed and safely performed. Best indication of POET is less than 5 cm esophageal leiomyoma. A novel endoscopic treatment of gastroesophageal reflux disease (GERD) was developed. Anti-reflux mucosectomy( ARMS) is nearly circumferential mucosal reduction of gastric cardia mucosa. ARMS is performed in 56 consecutive cases of refractory GERD. No major complications were encountered and excellent clinical results. Best indication of ARMS is a refractory GERD without long sliding hernia. Longest follow-up case is more than 10 years. Minimally invasive treatments for esophageal benign diseases are currently performed by therapeutic endoscopy.

    Advances in diagnostic modalities and improvement in surveillance programs for Barrett esophagus has resulted in an increase in the incidence of superficial esophageal cancers (SECs). SEC, due to their limited metastatic potential, are amenable to non-invasive treatment modalities. Endoscopic ultrasound, endoscopic mucosal resection, and endoscopic submucosal dissection (ESD) are some of the new modalities that gastroenterologists have used over the last decade to diagnose and treat SEC. However, esophageal stricture (ES) is a very common complication and a major cause of morbidity post-ESD. In the past few years, there has been a tremendous effort to reduce the incidence of ES among patients undergoing ESD. Steroids have shown the most consistent results over time with minimal complications although the preferred mode of delivery is debatable, with both systemic and local therapy having pros and cons for specific subgroups of patients. Newer modalities such as esophageal stents, autologous cell sheet transplantation, polyglycolic acid, and tranilast have shown promising results but the depth of experience with these methods is still limited. We have summarized case reports, prospective single center studies, and randomized controlled trials describing the various methods intended to reduce the incidence of ES after ESD. Indications, techniques, outcomes, limitations, and reported complications are discussed. PMID:26949124

    2014-01-01

    Eosinophilic esophagitis (EoE) is a recently recognized allergic disorder, characterized by eosophageal dysfunction, accumulation of ≥15 eosinophils/high-powered field, eosinophil microabssess, basal cell hyperplasia, extracellular eosinophilic granules in the esophageal epithelial mucosal biopsy and a lack of response to a 8-week proton pump inhibitor treatment. Despite the increased incidences and considerable progress made in understanding EoE pathogenesis, there are limited diagnostic and therapeutic options available for EoE. Currently, the only criterion for diagnosing EoE is repetitive esophageal endoscopic biopsies and histopathological evaluation. Antigen elimination or corticosteroid therapies are effective therapies for EoE but are expensive and have limitations, if continued in the long term. Hence, there is a great necessity for novel noninvasive diagnostic biomarkers that can easily diagnose EoE and assess effectiveness of therapy. Herein, we have provided an update on key molecules involved in the disease initiation, and progression and proposed novel noninvasive diagnostic molecules and strategies for EoE therapy.

    We review the current status of proteomics for esophageal cancer (EC) from a clinician's viewpoint. The ultimate goal of cancer proteomics is the improvement of clinical outcome. The proteome as a functional translation of the genome is a straightforward representation of genomic mechanisms that trigger carcinogenesis. Cancer proteomics has identified the mechanisms of carcinogenesis and tumor progression, detected biomarker candidates for early diagnosis, and provided novel therapeutic targets for personalized treatments. Our review focuses on three major topics in EC proteomics: diagnostics, treatment, and molecular mechanisms. We discuss the major histological differences between EC types, i.e., esophageal squamous cell carcinoma and adenocarcinoma, and evaluate the clinical significance of published proteomics studies, including promising diagnostic biomarkers and novel therapeutic targets, which should be further validated prior to launching clinical trials. Multi-disciplinary collaborations between basic scientists, clinicians, and pathologists should be established for inter-institutional validation. In conclusion, EC proteomics has provided significant results, which after thorough validation, should lead to the development of novel clinical tools and improvement of the clinical outcome for esophageal cancer patients. This article is part of a Special Issue entitled: Medical Proteomics.

    The present report describes a rare case of esophageal carcinoid tumor that was treated by endoscopic resection. A 43-year-old woman underwent esophagogastroduodenoscopy at her family clinic for screening of the upper digestive tract and a small lesion resembling a submucosal tumor was detected in the lower esophagus. A biopsy sample from the lesion was diagnosed as esophageal carcinoid tumor and the patient visited our hospital for detailed examination. The tumor was approximately 3 mm in diameter and its surface appeared to be covered with normal squamous epithelium. The tumor had a shiny reddish surface without ulceration or erosion. Magnifying endoscopy with narrow-band imaging showed structures resembling reticular vessels under the epithelium. Endoscopic ultrasonography depicted the tumor as a low-echoic mass within the lamina propria. Computed tomography did not detect the tumor and no metastatic lesions were evident in other organs. With the patient's informed consent, the tumor was resected using endoscopic submucosal dissection, with a sufficient free margin in both the vertical and horizontal directions. Magnifying endoscopic examination showed the resected tumor to have abundant reticular vessels. Finally, the tumor was diagnosed immunopathologically as an esophageal carcinoid tumor (neuroendocrine cell tumor, grade 1), without lymphatic or vascular invasion.

  7. A Review of Esophageal Chest Pain.

    2015-11-01

    Noncardiac chest pain is a term that encompasses all causes of chest pain after a cardiac source has been excluded. This article focuses on esophageal sources for chest pain. Esophageal chest pain (ECP) is common, affects quality of life, and carries a substantial health care burden. The lack of a systematic approach toward the diagnosis and treatment of ECP has led to significant disability and increased health care costs for this condition. Identifying the underlying cause(s) or mechanism(s) for chest pain is key for its successful management. Common etiologies include gastroesophageal reflux disease, esophageal hypersensitivity, dysmotility, and psychological conditions, including panic disorder and anxiety. However, the pathophysiology of this condition is not yet fully understood. Randomized controlled trials have shown that proton pump inhibitor therapy (either omeprazole, lansoprazole, or rabeprazole) can be effective. Evidence for the use of antidepressants and the adenosine receptor antagonist theophylline is fair. Psychological treatments, notably cognitive behavioral therapy, may be useful in select patients. Surgery is not recommended. There remains a large unmet need for identifying the phenotype and prevalence of pathophysiologic mechanisms of ECP as well as for well-designed multicenter clinical trials of current and novel therapies.

    Herpes simplex virus is a common cause of ulcerative esophagitis in the immunocompromised or debilitated host. Despite a high prevalence of primary and recurrent Herpes simplex virus infection in the general population, Herpes simplex virus esophagitis (HSVE) appears to be rare in the immunocompetent host. We report three cases of endoscopically-diagnosed HSVE in apparently immunocompetent children; the presentation was characterized by acute onset of fever, odynophagia, and dysphagia. In two cases, the diagnosis was confirmed histologically by identification of herpes viral inclusions and culture of the virus in the presence of inflammation. The third case was considered to have probable HSVE based on the presence of typical cold sore on his lip, typical endoscopic finding, histopathological evidence of inflammation in esophageal biopsies and positive serologic evidence of acute Herpes simplex virus infection. Two cases received an intravenous course of acyclovir and one had self-limited recovery. All three cases had normal immunological workup and excellent health on long-term follow-up.

    Important new advances were presented in esophageal disease in Digestive Disease Week 2013. A highlight was confirmation of the high efficacy of weight loss to treat symptoms of reflux and an interesting pilot study suggesting that a simple ligature with supra- and infracardial bands could be an effective technique in esophageal reflux. If the excellent results and safety and efficacy of this technique are confirmed in the long term, it could revolutionize the management of gastroesophageal reflux disease. Also of note this year was the presentation of multiple studies validating a new technique, peroral endoscopic myotomy (POEM) for the endoscopic treatment of achalasia. This technique seems to have excellent efficacy and safety.

    Scleroderma esophagus is characterized by ineffective peristalsis and reduced esophageal sphincter pressure. Esophageal disease in scleroderma can precede cutaneous manifestations and has been associated with Raynaud's phenomenon (RP) and pulmonary fibrosis (PF). The objective of the study is to evaluate the impact of cutaneous findings, RP, and PF on demographics, symptoms, and esophageal motility in patients with scleroderma. Scleroderma patients with esophageal involvement were included after review of esophageal manometries and charts over a 6-year period. High-resolution esophageal manometry was performed. Patients completed a symptom questionnaire. The study enrolled 28 patients (22 females; mean age 50.3 ± 12.8 years) with scleroderma esophagus. Patients without skin involvement (n= 12) reported more severe heartburn (P= 0.02), while those with cutaneous findings (n= 16) had more frequent dysphagia with solids (P= 0.02). Patients with RP (n= 22) had lower amplitude of distal esophageal contractions (P= 0.01) than those without RP (n= 6). Patients with PF (n= 11) reported more severe coughing and wheezing (both P= 0.03) than those without lung disease (n= 17). This study highlights subgroups of patients with scleroderma esophagus according to phenotypic findings of dermatologic changes, RP, and PF. Heartburn and dysphagia are important symptoms that may be associated with different stages of disease progression based on skin changes in scleroderma. RP was associated with greater esophageal dysmotility. Coughing and wheezing were more severe in patients with PF.

    Lymphocytic esophagitis (LE) is a clinicopathologic entity first described by Rubio et al in 2006. It is defined as peripapillary intraepithelial lymphocytosis with spongiosis and few or no granulocytes on esophageal biopsy. This definition is not widely accepted and the number of lymphocytes needed to make the diagnosis varied in different studies. Multiple studies have described potential clinical associations and risk factors for LE, such as old age, female gender and smoking history. This entity was reported in inflammatory bowel disease in the pediatric population but not in adults. Other associations include gastroesophageal reflux disease and primary esophageal motility disorders. The most common symptom is dysphagia, with a normal appearing esophagus on endoscopy, though esophageal rings, webs, nodularities, furrows and strictures have been described. Multiple treatment modalities have been used such as proton pump inhibitors and topical steroids. Esophageal dilation seems to be therapeutic when dysphagia is present along with esophageal narrowing secondary to webs, rings or strictures. The natural history of the disease remains unclear and needs to be better delineated. Overall, lymphocytic esophagitis seems to have a chronic and benign course, except for two cases of esophageal perforation in the literature, thought to be secondary to this entity. PMID:28246468

    Purpose: Patients who have been irradiated at the neck have an increased risk of symptomatic stenosis of the carotid artery during follow-up. Carotid angioplasty and stenting (CAS) can be a preferable alternative treatment to carotid endarterectomy, which is associated with increased operative risks in these patients. Methods and Materials: We performed a prospective cohort study of 24 previously irradiated patients who underwent CAS for symptomatic carotid stenosis. We assessed periprocedural and nonprocedural events including transient ischemic attack (TIA), nondisabling stroke, disabling stoke, and death. Patency rates were evaluated on duplex ultrasound scans. Restenosis was defined as a stenosis of >50% at the stent location. Results: Periprocedural TIA rate was 8%, and periprocedural stroke (nondisabling) occurred in 4% of patients. After a mean follow-up of 3.3 years (range, 0.3-11.0 years), only one ipsilateral incident event (TIA) had occurred (4%). In 12% of patients, a contralateral incident event was present: one TIA (4%) and two strokes (12%, two disabling strokes). Restenosis was apparent in 17%, 33%, and 42% at 3, 12, and 24 months, respectively, although none of the patients with restenosed vessels became symptomatic. The length of the irradiation to CAS interval proved the only significant risk factor for restenosis. Conclusions: The results of CAS for radiation-induced carotid stenosis are favorable in terms of recurrence of cerebrovascular events at the CAS site.

    Purpose. To describe short-term complications during stent placement for atherosclerotic renal artery ostial stenosis. Methods. Sixty-one arteries in 50 patients were treated with Palmaz stents. Nineteen patients had a single functioning kidney, 23 had a bilateral stenosis, which was stented bilaterally in 11, and 8 had a unilateral stenosis. The complications were grouped as those related to the catheterization procedure, those related to stent placement, and those possibly related to either category. The complications were divided into those with severe clinical significance (SCS), those with minor clinical significance (MCS), and radiological-technical complications (RTC). The stent placement procedures were ordered chronologically according to examination date and the complications were tabulated per group of 10 patients. Results. Five (10%) SCS, 5 (10%) MCS, and 8 (16%) RTC occurred in 50 patients. The catheterization procedure led to 2 SCS, 3 MCS, and 1 RTC. Stent placement gave rise to 7 RTC. Three SCS and 2 MCS could have been related to either catheterization or stent placement. More SCS occurred in the first group of 10 patients than in the following groups. Conclusion. Renal artery stent placement for atherosclerotic ostial stenosis has a considerable complication rate and a learning curve is present. The complications related to the actual stent placement were without clinical consequences.

    Purpose The purpose of this study was to describe clinical characteristics and prevalence of carotid stenosis in patients with amaurosis fugax (AF). Method Patients diagnosed with AF and subjected to carotid ultrasound in 2004–2010 in Sahlgrenska University Hospital, Gothenburg (n=302), were included, and data were retrospectively collected from medical records. Results The prevalence of significant carotid stenosis was 18.9%, and 14.2% of the subjects were subjected to carotid endarterectomy. Significant associations with risk of having ≥70% stenosis were male sex (adjusted odds ratio [aOR]: 2.62; 95% confidence interval [CI]: 1.26–5.46), current smoking (aOR: 6.26; 95% CI: 2.62–14.93), diabetes (aOR: 3.68; 95% CI: 1.37–9.90) and previous vasculitis (aOR: 10.78; 95% CI: 1.36–85.5). A majority of the patients (81.4%) was seen by an ophthalmologist prior to the first ultrasound. Only 1.7% of the patients exhibited retinal artery emboli at examination. Conclusion The prevalence of carotid stenosis among patients with AF is higher than has previously been demonstrated in stroke patients. An association with previously reported vascular risk factors and with vasculitis is seen in this patient group. Ocular findings are scarce. PMID:27826182

    [Purpose] Osteopoikilosis is a rare hereditary bone disease that is usually asymptomatic. It is generally diagnosed incidentally on plain radiography. The coexistence of osteopoikilosis with seronegative spondyloarthritis or spinal stenosis is rarely reported. Here, we report the case of a 27-year-old male patient with osteopoikilosis, seronegative spondyloarthritis, and spinal stenosis. [Subject] A 27-year-old male patient with buttock pain and back pain radiating to the legs. [Methods] A plain anteroposterior radiograph of the pelvis revealed numerous round and oval sclerotic bone areas of varying size. Investigation of the knee joints showed similar findings, and the patient was diagnosed with osteopoikilosis. Lumbar magnetic resonance images showed spinal stenosis and degenerative changes in his lumbar facet joints. Magnetic resonance images of the sacroiliac joints showed bilateral involvement with narrowing of both sacroiliac joints, nodular multiple sclerotic foci, and contrast enhancement in both joint spaces and periarticular areas. HLA B-27 test was negative. [Results] The patient was diagnosed with osteopoikilosis, seronegative spondyloarthritis, and spinal stenosis. Treatment included asemetasin twice daily and exercise therapy. [Conclusion] Symptomatic patients with osteopoikilosis should be investigated for other possible coexisting medical conditions; this will shorten the times to diagnosis and treatment. PMID:26157277

    Stenosis of the aqueduct of Sylvius accounts for about one third of cases of congenital hydrocephalus. At least 32 families have been reported in which the aqueduct stenosis is inherited in an X linked fashion. In half of these families, flexed adducted thumbs were noted in some affected family members. Occasionally other male members were mentally retarded, suggesting limited expression of the gene. The problem of giving genetic advice to an isolated, clinically unremarkable, case of aqueduct stenosis remains, so a family study was undertaken based on 24 such cases seen at The Hospital for Sick Children over a 19-year period. There were 15 male and nine female index patients. The diagnosis was confirmed in all cases by air encephalogram. One boy had a radial club hand and another developed clasped thumbs secondary to spasticity. No cases had hyaloidoretinal dysplasia. The 15 boys had 18 brothers and 19 sisters, of whom one sister was similarly affected. The nine girls had 12 sibs, none of whom was affected. This study, combined with a similar study in the USA, suggests that the empirical risk of recurrence of a sporadic case of aqueduct stenosis is about 4.5%. PMID:7277416

  9. Proton pump inhibitor responsive esophageal eosinophilia, a distinct disease entity?

    PubMed

    Munday, William; Zhang, Xuchen

    2014-08-14

    Recent studies have suggested the existence of a patient population with esophageal eosinophilia that responds to proton pump inhibitor therapy. These patients are being referred to as having proton pump inhibitor responsive esophageal eosinophilia (PPI-REE), which is currently classified as a distinct and separate disease entity from both gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE). The therapeutic effect of proton pump inhibitor (PPI) on PPI-REE is thought to act directly at the level of the esophageal mucosa with an anti-inflammatory capacity, and completely independent of gastric acid suppression. The purpose of this manuscript is to review the mechanistic data of the proposed immune modulation/anti-inflammatory role of the PPI at the esophageal mucosa, and the existence of PPI-REE as a distinct disease entity from GERD and EoE.

    Approximately 20-30% of patients with gastro-esophageal reflux symptoms report inadequate symptom relief while on proton-pump inhibitor therapy. The mechanisms involved are failure of the antireflux barrier (transient lower esophageal sphincter relaxations), high proximal extent of the refluxate, esophageal hypersensitivity and impaired mucosal integrity. Persisting acid or nonacid reflux can be demonstrated in 40-50% of cases, suggesting that there is room for antireflux therapy in these patients. New antireflux compounds have been shown to decrease the occurrence of transient lower esophageal sphincter relaxations. The most promising classes of compounds are GABA type B agonists and metabotropic glutamate receptor 5 antagonists, which can reduce both reflux episodes and symptoms, but the development of these compounds has been abandoned for either safety issues or lack of efficacy. Esophageal hypersensitivity and impaired mucosal integrity may prove to be relevant therapeutic targets in the future.

    Esophageal melanosis which is characterized by melanocytic proliferation in the squamous epithelium of the esophagus and melanin accumulatin of esophageal mucosa (EM) is a rare disease of the digestive system. Although esophageal melanosis is considered to be a benign disease, its etiology is not cleared and has been reported to be the precursor lesion of esophageal primary melanomas. In this report, we aimed to note esophageal melanosis in a 55-year-old female case who applied to our clinic with difficulty in swallowing, burning behind the breastbone in the stomach, heartburn, indigestion, and pain in the upper abdomen after endoscopic and pathologic evaluation. Complaints dropped with anti-acid therapy and case was followed by intermittent endoscopic procedures because of precursor melanocytic lesions. PMID:27785326

    Carotid artery stenosis is a well-established risk factor of ischemic stroke, contributing to up to 10%-20% of strokes or transient ischemic attacks. Many clinical trials over the last 20 years have used measurements of carotid artery stenosis as a means to risk stratify patients. However, with improvements in vascular imaging techniques such as CT angiography and MR angiography, ultrasonography, and PET/CT, it is now possible to risk stratify patients, not just on the degree of carotid artery stenosis but also on how vulnerable the plaque is to rupture, resulting in ischemic stroke. These imaging techniques are ushering in an emerging paradigm shift that allows for risk stratifications based on the presence of imaging features such as intraplaque hemorrhage (IPH), plaque ulceration, plaque neovascularity, fibrous cap thickness, and presence of a lipid-rich necrotic core (LRNC). It is important for the neurosurgeon to be aware of these new imaging techniques that allow for improved patient risk stratification and outcomes. For example, a patient with a low-grade stenosis but an ulcerated plaque may benefit more from a revascularization procedure than a patient with a stable 70% asymptomatic stenosis with a thick fibrous cap. This review summarizes the current state-of-the-art advances in carotid plaque imaging. Currently, MRI is the gold standard in carotid plaque imaging, with its high resolution and high sensitivity for identifying IPH, ulceration, LRNC, and inflammation. However, MRI is limited due to time constraints. CT also allows for high-resolution imaging and can accurately detect ulceration and calcification, but cannot reliably differentiate LRNC from IPH. PET/CT is an effective technique to identify active inflammation within the plaque, but it does not allow for assessment of anatomy, ulceration, IPH, or LRNC. Ultrasonography, with the aid of contrast enhancement, is a cost-effective technique to assess plaque morphology and characteristics, but it is

    Lower esophageal sphincter (LES) relaxation and esophageal body inhibition co-occur during esophageal peristalsis but not necessarily during pharyngeal stimulation or transient LES relaxation (tLESR). This study examined these relationships and the impact on reflux. Nine young volunteers were studied. An artificial high-pressure zone (HPZ) was established, and pH was recorded 8 and 5 cm proximal to the LES. Pharyngeal stimulation was by water injection and gastric distension with liquid or gas. Peristalsis, pharyngeal stimulation, and spontaneous events were recorded. Swallowing relaxed the LES in 100% of trials (the HPZ in 80%) and caused no reflux. Pharyngeal stimulation relaxed the LES in two-thirds of trials, had no effect on the HPZ, and caused no reflux. Gastric distension was associated with 117 tLESRs, 48% with acid reflux, and 32% with gas reflux; there was no effect on the HPZ. We conclude that LES relaxation is a necessary but not sufficient condition for reflux. LES relaxation and esophageal body inhibition are independent events that may be concurrent (swallowing) or dissociated (tLESR).

    OBJECTIVE: Esophageal squamous cell carcinoma is one of the most common esophageal diseases in the developing world, but the relationship between esophageal squamous cell carcinoma and Helicobacter pylori infection remains a neglected topic. The primary objective of this study was to determine the association between Helicobacter pylori infection and esophageal squamous cell carcinoma. A second purpose was to determine the incidence and factors associated with Helicobacter pylori infection following esophagectomy. METHOD: The microorganism was identified by testing the gastric biopsy materials from 95 esophageal squamous cell carcinoma patients (66 females; 39 were esophagectomized) for urease activity in a medium containing urea and a power of hydrogen detection reagent and comparing the results with those from a healthy population. Differences in patient characteristics were assessed with chi-square tests and t-tests for categorical and continuous factors, respectively. RESULTS: The patients with esophageal squamous cell carcinoma had a significantly lower prevalence of Helicobacter pylori compared with the healthy population (p<0.001). The naive and esophagectomized patients, in contrast, showed no significant differences in Helicobacter pylori infection (p>0.005). Patients with esophageal squamous cell carcinoma showed a significant association between leukocytosis and hypoglobulinemia and the presence of Helicobacter pylori infection (p=0.023 and p=0.045, respectively). CONCLUSION: These results suggest that Helicobacter pylori is not an etiological factor in patients with esophageal squamous cell carcinoma. We found a statistically significant negative correlation between esophageal squamous cell cancer and Helicobacter pylori infection. These findings may guide new strategies for esophageal squamous cell carcinoma therapy. PMID:28355360

    Five cases of supravalvular aortic stenosis (SAS) diagnosed by heart catheterization were studied in the Instituto Nacional de Cardiologia of Mexico. The clinic and laboratory data of interest of the differential diagnosis with other forms of obstruction of the left ventricle as follows: 1. Three cases had mental retardation and "elfin" face (SAS with specific psychophysical syndrome), the rest had a normal psyco-physical state without family antecedents (sporadic SAS). 2. The aortic focus was the epicenter of the expulsion murmur. In the phoncarodiographic study, two patients had protosistolic click and another had, in addition, a descending protodiastolic murmur (Int. I-IV). In the radial sphigmograms, one case had an amplitude difference in favor of the right side. 3. All had serum calcium figures within normal limits. 4. A chromosomatic analysis of preperipheral blood was performed on two patients, with normal results. 5. In the electrocardiogram, one case had right ventricular enlargement secondary to pulmonary arterial hypertension, due to stenosis of the main pulmonary arteries. 6. The radiologic study did not show dilatation of the ascending aorta and aortic bud in any case. 7. The angiocardiography showed: stenosis directly above the Valsalva sinuses; absence of dilatation or hypoplasia of the aorta above the stenosis; and the coronary network, indirectly opaqued, showed no abnormalities. One case had aortic coarctation and abnormal implantation of the right sublaviar artery, and another, stenosis of the right and left branch of its origen of the truncus of the pulmonary artery. The literature up to the present is reviewed and an anatomo-functional classification is proposed with the objective of including new varieties.

    Eosinophilic Esophagitis (EoE) is a chronic allergic disorder, whose pathobiology is incompletely understood. Histamine-producing cells including mast cells and basophils have been implicated in EoE. However, very little is currently known about the role of histamine and histamine receptor (HR) expression and signaling in the esophageal epithelium. Herein, we characterized HR (H1R, H2R, H3R, and H4R) expression in human esophageal biopsies and investigate the role of histamine signaling in inducible cytokine expression in human esophageal epithelial cells in vitro. HR expression was quantified in esophageal biopsies from non-EoE control (N = 23), inactive EoE (<15 eos/hpf, N = 26) and active EoE (>15 eos/hpf, N = 22) subjects using qRT-PCR and immunofluorescent localization. HR expression and histamine-mediated cytokine secretion were evaluated in human primary and telomerase-immortalized esophageal epithelial cells. H1R, H2R, and H4R expression were increased in active EoE biopsies compared to inactive EoE and controls. H2R was the most abundantly expressed receptor, and H3R expression was negligible in all 3 cohorts. Infiltrating eosinophils expressed H1R, H2R, and H4R, which contributed to the observed increase in HR in active subjects. H1R and H2R, but not H3R or H4R, were constitutively expressed by primary and immortalized cells, and epithelial histamine stimulation induced GM-CSF, TNFα, and IL-8, but not TSLP or eotaxin-3 secretion. Epithelial priming with the TLR3 ligand poly (I:C) induced H1R and H2R expression, and enhanced histamine-induced GM-CSF, TNFα, and IL-8 secretion. These effects were primarily suppressed by H1R antagonists, but unaffected by H2R antagonism. Histamine directly activates esophageal epithelial cytokine secretion in vitro in an H1R dependent fashion. However, H1R, H2R and H4R are induced in active inflammation in EoE in vivo. While systemic antihistamine (anti-H1R) therapy may not induce clinical remission in EoE, our study

    From January 1985 to December 1994, 23 early stage carcinomas of the esophagus were treated by photodynamic therapy in 21 patients. The stage of the tumors was assessed by esophagoscopy with multiple biopsies, CT scan and, from June 1991, also by endoscopic ultrasonography: 7 lesions were classified as carcinoma in situ (Tis) and 16 as invasive (T1). The photosensitizers used for PDT were hematoporphyrin derivative 3 mg/kg in 4 patients and dihematoporphyrin ether 2 mg/kg in 17. Light irradiation was performed using an Argon-dye laser system at a wavelength of 630 nm with an average energy of 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. A complete response was achieved in 17/23 (74%) tumors, 15/21 (71%) patients. In the follow-up period from 6 to 78 months (median 36 months) 3 recurrences occurred 6, 12, and 14 months after PDT, respectively. Seven patients died due to concomitant diseases, not related to tumor progression. The actuarial survival rate was 95%, 75% and 37% at 1, 3, and 5 years, respectively. Complications included 1 case of sunburn and 2 cases of esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage.

    Objectives Esophageal dilation is commonly performed in eosinophilic esophagitis (EoE), but there are few long-term data. The aims of this study were to assess the safety and long-term efficacy of esophageal dilation in a large cohort of EoE cases and determine the frequency and predictors of requiring multiple dilations. Methods We conducted a retrospective cohort study in the University of North Carolina EoE clinicopathological database from 2002-2014. Included subjects met consensus diagnostic criteria for EoE. Clinical, endoscopic, and histologic features were extracted, as were dilation characteristics (dilator type, change in esophageal caliber, total number of dilations) and complications. Patients with EoE who had undergone dilation were compared to those who did not and also stratified by whether they required single or multiple dilations. Results Of 509 EoE patients, 164 were dilated a total of 486 times. Those who underwent dilation had a longer duration of symptoms prior to diagnosis (11.1 vs. 5.4 yrs, p<0.001). 95 patients (58%) required >1 dilation (417 dilations total, mean of 4.4 ± 4.3 per patient). The only predictor of requiring multiple dilations was a smaller baseline esophageal diameter. Dilation was tolerated well, with no major bleeds, perforations, or deaths. The overall complication rate was 5%, primarily due to post-procedural pain. Of 164 individuals dilated, a majority (58%, or 95/164) required a second dilation. Of these individuals, 75% required dilation within 1 year. Conclusions Dilation in EoE is well-tolerated, with a very low risk of serious complications. Patients with long-standing symptoms prior to diagnosis are likely to require dilation. More than half of those dilated will require multiple dilations, often needing a second procedure within one year. These findings can be used to counsel patients with fibrostenotic complications of EoE. PMID:26753894

    Although direct volume rendering (DVR) has become a commodity, effective rendering of interesting features is still a challenge. In one of active DVR application fields, the medicine, radiologists have used DVR for the diagnosis of lesions or diseases that should be visualized distinguishably from other surrounding anatomical structures. One of most frequent and important radiologic tasks is the detection of lesions, usually constrictions, in complex tubular structures. In this paper, we propose a 3D spatial field for the effective visualization of constricted tubular structures, called as a stenosis map which stores the degree of constriction at each voxel. Constrictions within tubular structures are quantified by using newly proposed measures (i.e. line similarity measure and constriction measure) based on the localized structure analysis, and classified with a proposed transfer function mapping the degree of constriction to color and opacity. We show the application results of our method to the visualization of coronary artery stenoses. We present performance evaluations using twenty eight clinical datasets, demonstrating high accuracy and efficacy of our proposed method. The ability of our method to saliently visualize the constrictions within tubular structures and interactively adjust the visual appearance of the constrictions proves to deliver a substantial aid in radiologic practice.

    Background Esophageal cancer (EC) occurs commonly, especially in Asia, and is the sixth leading cause of cancer deaths worldwide. Recently, great progress has been made in research on the etiology and prevention of EC. Summary The major risk factors for esophageal squamous cell carcinoma (ESCC) are tobacco smoking and alcohol drinking, which act synergistically. Dietary parameters, including dietary carcinogens and insufficiency of micronutrients, could also be important risk factors in certain areas. A common etiological factor for both EC and some other cancers are low levels of intake of fruits and vegetables. With improvements in diet and drinking water in developing countries, the incidence of ESCC decreased. However, in economically well-developed countries, the incidence of esophageal adenocarcinoma (EAC) has markedly increased in the past 40 years. The major etiological factor for EAC is gastroesophageal reflux, which is also an etiological factor for gastric cardia adenocarcinoma (GCA). In certain areas of China, the occurrence of GCA is closely related to ESCC. Susceptibility genes for EC are starting to be discovered, and this may help to identify high-risk groups that have more need for preventive measures. Mitigation of the risk factors, early detection and treatment of precancerous lesions are effective approaches for prevention. Smoking cessation, avoidance of excessive alcohol, meat and caloric consumption, increasing physical activity and frequent consumption of vegetables and fruits are prudent lifestyle modifications for the prevention of EC as well as other diseases. Key Message The etiology of EC includes tobacco smoking, alcohol drinking, low levels of intake of fruits and vegetables as well as gastroesophageal reflux and susceptibility genes. Practical Implications A healthy lifestyle including smoking cessation, increasing physical activity, consumption of vegetables as well as reduction of alcohol intake and caloric consumption are major

    OBJECTIVE--To determine the incidence and prognosis of congenital aortic valve stenosis in the five Health Districts of Liverpool that make up the Merseyside area. DESIGN--The records of the Liverpool Congenital Malformations Registry and the Royal Liverpool Children's Hospital identified 239 patients (155 male, 84 female) born with aortic valve stenosis between 1960 and 1990. Patients were traced to assess the severity of stenosis at follow up. Information on the severity at presentation and all subsequent events was obtained. RESULTS--Congenital aortic valve stenosis occurred in 5.7% of patients with congenital heart disease born in the Merseyside area. The median age at presentation was 16 months (range 0-20 years). Stenosis was mild at presentation in 145 patients, moderate in 33, severe in one and critical in 21 and 39 had a bicuspid valve without stenosis. Additional cardiac lesions were significantly more common in children presenting under one year of age and in those with critical stenosis. The median duration of follow up was 9.2 years (range 1-28 years) and seven patients were lost to follow up. 81 operations were performed in 60 patients. The reoperation rate was 28.3% after a median duration of 8.7 years (range 2.5-18 years). 15% of patients who presented with mild stenosis subsequently required operation compared with 67% of those with moderate stenosis. There were no sudden unexpected deaths and no deaths after aortic valvotomy, except in those presenting with critical stenosis. Mortality was 16.7% but patients presenting with critical aortic stenosis had a much worse prognosis. Actuarial and hazard analysis showed that the survival and absence of serious events (aortic valve surgery or balloon dilatation, endocarditis, or death) were significantly better in patients who presented with mild aortic stenosis than in those who presented with moderate aortic stenosis. 75% of patients presenting with mild stenosis had not progressed to moderate stenosis

    The treatment of locally advanced esophageal cancer is controversial. For patients who are candidates for surgical resection, multiple prospective clinical trials have demonstrated the advantages of neoadjuvant chemoradiation. For patients who are medically inoperable, definitive chemoradiation is an alternative approach with survival rates comparable to trimodality therapy. Although trials of dose escalation are ongoing, the standard radiation dose remains 50.4 Gy. Modern radiotherapy techniques such as image-guided radiation therapy with motion management and intensity-modulated radiation therapy are strongly encouraged with a planning objective to maximize conformity to the intended target volume while reducing dose delivered to uninvolved normal tissues.

    A 7-mo-old female cougar (Puma concolor) was presented with a 2-wk history of anorexia and a 1-wk history of regurgitation. Barium contrast esophagogram and gastroesophagoscopy revealed the presence of a segmental intraluminal esophageal stricture in the middle third of the esophagus. The stricture was potentially secondary to a previous anesthetic episode. Three endoscopic balloon dilations allowed increasing the luminal diameter to a size that enabled the cougar to eat food softened with water without any signs of discomfort or regurgitation. Two months after being discharged, the cougar was doing well, had gained weight and was eating horsemeat softened with water.

    Summary Percutaneous transluminal angioplasty (PTA) has recently become a noteworthy treatment option for significant stenosis involving the vertebral artery (VA) in selected patients. We conducted a prospective study to evaluate the efficacy, safety and mid-term follow up results of 206 cases received PTA with or without stent implant to treat their symptomatic atherosclerotic VA stenosis in all segments (V1-V4). In a prospective mono-arm trial from October 2008 to July 2012 in a single center, 239 lesions affecting the intra or extracranial VA (171 in V1, 17 in V2, 14 in V3, 21 in V4 and 16 in combined segments) were treated by PTA with or without stent implant. Non-disabling stroke patients who had failed conservative medical treatment and had angiographic evidence of >50% stenosis in the dominant VA with clinical signs and symptoms of VB stenosis were included in this study. They were mean followed for 13.15±5.24 months after treatment. Overall, 206 patients underwent the procedure. A stent was implemented in 199 patients (96.6%). The periprocedural complication rate was 7.2%. The procedural (technical) success rate was 97.6%. Of the total 239 lesions, 223 were treated with stent implant. Clinical success was achieved in all 206 symptomatic patients after the procedure. Restenosis occurred in 15.9% after a mean 10.8 (6-24) months. Of those, 63.1% and 34.2% had mild and moderate stenosis that was treated medically, whereas one case (2.6%) with severe restenosis underwent balloon angioplasty. No deaths occurred during the follow-up period. The follow-up complication rate was 6.3%. TIA occurred in 4.4%, a minor stroke in 1.4% and a major stroke in one patient. The overall patient event-free survival was 92.4%. These results demonstrate the safety and feasibility of PTA with or without stent implant, with a high technical success rate, a low complication rate, a low restenosis rate and durable clinical success in patients with symptomatic VA stenosis.

    Esophageal carcinoma affects more than 450000 people worldwide and the incidence is rapidly increasing. In the United States and Europe, esophageal adenocarcinoma has superseded esophageal squamous cell carcinoma in its incidence. Esophageal cancer has a high mortality rates secondary to the late presentation of most patients at advanced stages. Endoscopic screening is recommended for patients with multiple risk factors for cancer in Barrett’s esophagus. These risk factors include chronic gastroesophageal reflux disease, hiatal hernia, advanced age, male sex, white race, cigarette smoking, and obesity. The annual risk of esophageal cancer is approximately 0.25% for patients without dysplasia and 6% for patients with high-grade dysplasia. Twenty percent of all esophageal adenocarcinoma in the United States is early stage with disease confined to the mucosa or submucosa. The significant morbidity and mortality of esophagectomy make endoscopic treatment an attractive option. The American Gastroenterological Association recommends endoscopic eradication therapy for patients with high-grade dysplasia. Endoscopic modalities for treatment of early esophageal adenocarcinoma include endoscopic resection techniques and endoscopic ablative techniques such as radiofrequency ablation, photodynamic therapy and cryoablation. Endoscopic therapy should be precluded to patients with no evidence of lymphovascular invasion. Local tumor recurrence is low after endoscopic therapy and is predicted by poor differentiation of tumor, positive lymph node and submucosal invasion. Surgical resection should be offered to patients with deep submucosal invasion. PMID:25132925

    2014-11-01

    Esophageal hypomotility (EH) is characterized by abnormal esophageal peristalsis, either from a reduction or absence of contractions, whereas spastic motor disorders (SMD) are characterized by an increase in the vigor and/or propagation velocity of esophageal body contractions. Their pathophysiology is not clearly known. The reduced excitation of the smooth muscle contraction mediated by cholinergic neurons and the impairment of inhibitory ganglion neuronal function mediated by nitric oxide are likely mechanisms of the peristaltic abnormalities seen in EH and SMD, respectively. Dysphagia and chest pain are the most frequent clinical manifestations for both of these dysfunctions, and gastroesophageal reflux disease (GERD) is commonly associated with these motor disorders. The introduction of high-resolution manometry (HRM) and esophageal pressure topography (EPT) has significantly enhanced the ability to diagnose EH and SMD. Novel EPT metrics in particular the development of the Chicago Classification of esophageal motor disorders has enabled improved characterization of these abnormalities. The first step in the management of EH and SMD is to treat GERD, especially when esophageal testing shows pathologic reflux. Smooth muscle relaxants (nitrates, calcium channel blockers, 5-phosphodiesterase inhibitors) and pain modulators may be useful in the management of dysphagia or pain in SMD. Endoscopic Botox injection and pneumatic dilation are the second-line therapies. Extended myotomy of the esophageal body or peroral endoscopic myotomy (POEM) may be considered in highly selected cases but lack evidence.

    Eosinophilic esophagitis (EoE) is a chronic antigen-mediated immune disease of the esophagus characterized by symptoms related to esophageal dysfunction, as well as significant esophageal eosinophilia. Although dense eosinophilia is the hallmark of EoE, other characteristic histologic features have been described that may help distinguish EoE from other competing diagnoses, although none are specific to EoE. One or more foods and, at times, environmental allergens trigger EoE. Left untreated, esophageal inflammation in EoE may lead to esophageal remodeling and stricture formation. Symptoms in EoE vary with age, as they relate to the progression of the disease from an inflammatory to a fibrostenotic phenotype over time. There are currently no U.S. Food and Drug Administration-approved therapies for EoE. Current options include various dietary-restriction therapies, topical corticosteroids, and esophageal dilations. Several emerging therapies aiming at restoring the esophageal barrier function or targeting various inflammatory cells or their mediators are under investigation.

    Eosinophilic esophagitis (EoE) is an emerging allergic, IgE- and non-IgE (Th2 cell)-mediated disease. There are major gaps in the understanding of the basic mechanisms that drive the persistence of EoE. We investigated whether esophageal biopsies from children with EoE demonstrate an inflammatory response that is distinct from normal controls. We prospectively enrolled 84 patients, of whom 77 were included in our analysis, aged 4–17 years (12.8±3.8 years; 81% males). Five esophageal biopsies were collected from each patient at the time of endoscopy. Intramucosal lymphocytes were isolated, phenotyped and stimulated with phorbol 12-myristate 13-acetate/ionomycin to measure their potential to produce cytokines via flow cytometry. We also performed cytokine arrays on 72-h biopsy culture supernatants. CD8+ T cells, compared with CD4+ T cells, synthesized more TNF-α and interferon (IFN)-γ after mitogen stimulation in the EoE-New/Active vs EoE-Remission group (P=0.0098; P=0.02) and controls (P=0.0008; P=0.03). Culture supernatants taken from explant esophageal tissue contained 13 analytes that distinguished EoE-New/Active from EoE-Remission and Controls. Principal component analysis and cluster analysis based on these analytes distinctly separated EoE-New/Active from EoE-Remission and Controls. In summary, we have identified a previously unappreciated role for CD8+ T lymphocytes with potential to produce TNF-α and IFN-γ in EoE. Our results suggest that CD8+ T cells have a role in the persistence or progression of EoE. We have also identified a panel of analytes produced by intact esophageal biopsies that differentiates EoE-New/Active from EoE-Remission and controls. Our results suggest that esophageal epithelial cells may have specific immune effector functions in EoE that control the type and amplitude of inflammation. PMID:27525061

    Background Positive esophageal proximal resection margin (ERM+) following esophagectomy was considered as incomplete or R1 resection. The clinicopathological data and long-term prognosis of esophageal cancer (EC) patients with ERM+ after esophagectomy were still unknown. Therefore, the aim of this study was to assess the clinical significance of ERM+ and its therapeutic option. Methods From November 2008 to December 2014, 3,594 patients with histologically confirmed EC underwent radical resection in our department. Among them there were 37 patients (1.03%) who had ERM+. ERM+ was defined as carcinoma or atypical hyperplasia (severe or moderate) at the residual esophageal margin in our study. For comparison, another 74 patients with negative esophageal proximal resection margin (ERM−) were propensity-matched at a ratio of 1:2 as control group according to sex, age, tumor location and TNM staging. The relevant prognostic factors were investigated by univariate and multivariate regression analysis. Results In this large cohort of patients, the rate of ERM+ was 1.03%. The median survival time was 35.000 months in patients with ERM+, significantly worse than 68.000 months in those with ERM− (Chi-square =4.064, P=0.044). Survival in patients with esophageal residual atypical hyperplasia (severe or moderate) was similar to those with esophageal residual carcinoma. Survival rate in stage I–II was higher than that in stage III–IV (Chi-square =27.598, P=0.000) in ERM−; But there was no difference between the two subgroups of patients in ERM+. Furthermore, in those patients with ERM+, survival was better in those who having adjuvant therapy, compared to those without adjuvant therapy (Chi-square =5.480, P=0.019). And the average survival time which was improved to a well situation for ERM+ patients who have adjuvant therapy was 68.556 months which is comparable to average survival time (65.815 months) of ERM− for those patients who are at earlier stages

    The article presents the case of a 68-year-old patient with alcohol dependence syndrome, who was admitted, in serious condition, to the Department of Surgery due to esophageal intramural lesions of unclear etiology. The imaging studies showed no signs of transmural perforation of the esophageal wall. Esophagogastroscopy revealed intramural fluid reservoirs and small oval cavities with smooth edges in the esophageal mucosa. The patient was treated conservatively with parenteral nutrition and rehabilitation. Subsequently, the patient was transferred to the intensive care unit because of cardiorespiratory failure. Despite adequate pharmacological treatment, the patient died. PMID:27785146

    The incidence of late radiation injury of the esophagus is not precisely determined but, overall, the occurrence of clinically apparent damage is infrequent. The authors report a complete esophageal obstruction in a 21-year-old man, 14 years after chemo-radiation therapy for Hodgkin's lymphoma. Although endoscopy failed to demonstrate a gross morphologic abnormality, an esophagogram detected abnormal peristalsis and stricture, and esophageal manometry coupled with dynamic isotopic study clearly demonstrated a multilevel secondary neuronal damage. Data in the literature suggest that alteration in motility is by far the most frequent radiologic manifestation. Further prospective studies will probably clarify the actual incidence of late esophageal damage after chemo-radiation therapy.

    Diffuse esophageal spasm (DES) causes chest pain and/or dysphagia in adults. We reviewed charts of 278 subjects 0 to 18 years of age after esophageal manometry to describe the frequency and characteristics of DES in children. Patient diagnoses included normal motility (61%), nonspecific esophageal motility disorder (20%), DES (13%, n=36), and achalasia (4%). Of patients with DES, the most common chief complaint was food refusal in subjects younger than 5 years (14/24, 58%) and chest pain in subjects older than 5 years (4/12, 33%). Comorbid medical conditions, often multiple, existed in 33 subjects. DES should be considered when young children present with food refusal.

    In childhood, the surgical treatment of gastroesophageal reflux is the main cause of dumping syndrome. We report the cases of 2 children with esophageal atresia who presented with dumping syndrome without any precipitating known factors, such as gastroesophageal reflux surgery or associated microgastria. Our data suggest (1) that dumping syndrome can occur after primary anastomosis of esophageal atresia without antireflux surgery and (2) that dumping syndrome should be considered in every child treated surgically for esophageal atresia presenting with digestive symptoms, malaise, failure to thrive, or refusal to eat.

    We have recently shown that HMGA2 is overexpressed in esophageal squamous cell carcinoma (ESCC) and its detection allows to discriminate between cancer and normal surrounding tissue proposing HMGA2 as a novel diagnostic marker. Interestingly, esophageal adenocarcinoma shows an opposite behavior with the overexpression of HMGA1 but not HMGA2. Moreover, we show that the suppression of HMGA2 in 2 ESCC cell lines reduces the malignant phenotype. Then, this paper highlights a differential induction of the HMGA proteins, depending on the cancer histological type, and reinforces the perspective of an innovative esophageal cancer therapy based on the suppression of the HMGA protein function and/or expression.

    Esophageal injury following blunt trauma to chest is an extremely rare event, with only a limited number of cases being reported in the world literature. We report a case of perforation of the lower thoracic esophagus following a crush injury to the chest in a 14 year old child. An appropriately placed chest drain and decompression gastrostomy resulted in complete resolution of the esophageal leak within four weeks. This case report demonstrates that a conservative approach to lower thoracic esophageal perforations can be carried out successfully without the added morbidity of thoracotomy and risks of direct repair.

    We measured quantitative esophageal transit, expressed as percentage of esophageal retention, before and after pneumatic dilatation in two patients with achalasia. In the sitting position they ingested a 500 ml liquid meal containing 500 muCi technetium Tc 99m sulfur colloid. Radioactivity counts of the entire esophagus were plotted at five-minute intervals for 30 minutes. In five normal control subjects the esophagus essentially cleared in less than one minute. Both patients with achalasia had definite retention 30 minutes before dilatation and had quantitative improvement after dilatation. Radionuclide scintigraphic esophageal transit probably correlates better than other parameters with the physiologic degree of obstruction in achalasia.

    Lymphocytic esophagitis is a chronic condition that has been described in the literature; however, there is little information describing its characteristics and treatment. We present a case of lymphocytic esophagitis that was identified following food impaction. Repeat esophagogastroduodenoscopy (EGD) with biopsy showed a marked decrease in lymphocytic infiltration after a 6-week course of twice-daily high-dose proton pump inhibitor (PPI). After initiation of the high-dose PPI regimen, the patient had no further episodes of dysphagia or food impaction. We propose that treating lymphocytic esophagitis with twice-daily PPI can improve symptoms and show histologic evidence of improvement. PMID:28119946

    Reversible thermal injury to the esophagus as the result of drinking hot liquids has been reported to generate alternating white and red linear mucosal bands, somewhat reminiscent of a candy cane. This phenomenon is associated with chest pain, dysphagia, odynophagia, and epigastric pain. Here, we report a case of thermal injury to the esophageal and oral cavity due to the drinking of hot tea, including odynophagia and dysphagia. A 69-year-old man was referred due to a difficulty in swallowing which had begun a week prior to referral. The patient, at the time of admission, was unable to swallow even liquids. He had recently suffered from hiccups, and had consumed five cups of hot adlay tea one week prior to admission, as a folk remedy for the hiccups. Upon physical examination, the patient's oral cavity evidenced mucosal erosion, hyperemia, and mucosa covered by a whitish pseudomembrane. Nonspecific findings were detected on the laboratory and radiological exams. Upper endoscopy revealed diffuse hyperemia, and erosions with thick and whitish pseudomembraneous mucosa on the entire esophagus. The stomach and duodenum appeared normal. We diagnosed the patient with thermal esophageal injury inflicted by the hot tea. He was treated with pantoprazole, 40 mg/day, for 14 days, and evidenced significant clinical and endoscopic improvement.

    The emerging application of long-term and high-quality ECG recording requires alternative electrodes to improve the signal quality and recording capability of surface skin electrodes. The esophageal ECG has the potential to overcome these limitations but necessitates novel recorder and lead designs. The electrode material is of particular interest, since the material has to ensure conflicting requirements like excellent biopotential recording properties and inertness. To this end, novel electrode materials like PEDOT and silver-PDMS as well as established electrode materials such as stainless steel, platinum, gold, iridium oxide, titanium nitride, and glassy carbon were investigated by long-term electrochemical impedance spectroscopy and model-based signal analysis using the derived in vitro interfacial properties in conjunction with a dedicated ECG amplifier. The results of this novel approach show that titanium nitride and iridium oxide featuring microstructured surfaces did not degrade when exposed to artificial acidic saliva. These materials provide low electrode potential drifts and insignificant signal distortion superior to surface skin electrodes making them compatible with accepted standards for ambulatory ECG. They are superior to the noble and polarizable metals such as platinum, silver, and gold that induced more signal distortions and are superior to esophageal stainless steel electrodes that corrode in artificial saliva. The study provides rigorous criteria for the selection of electrode materials for prolonged ECG recording by combining long-term in vitro electrode material properties with ECG signal quality assessment.

    The incidence of gastro-esophageal disease and associated rate of esophageal adenocarcinoma (EAC) is rising at an exponential rate in the United States. However, research targeting EAC is lagging behind, and much research is needed in the field to identify ways to diagnose EAC early as well as to improve the rate of pathologic complete response (pCR) to systemic therapies. Esophagectomy with subsequent reconstruction is known to be a morbid procedure that significantly impacts a patient's quality of life. If indeed the pCR rate of patients can be improved and those patients destined to be pCR can be identified ahead of time, they may be able to avoid this life-altering procedure. While cancer-specific biological pathways have been thoroughly investigated in other solid malignancies, much remains unexplored in EAC. In this review, we will highlight some of the latest research in the field in regards with EAC, along with new therapeutic targets that are currently being explored. After reviewing conventional treatment and current changes in medical therapy for EAC, we will focus on unchartered grounds such as cancer stem cells, genetics and epigenetics, immunotherapy, and chemoradio-resistant pathways as we simultaneously propose some investigational possibilities that could be applicable to EAC.

    Esophageal cancer is one of the fastest rising forms of cancer in the Western world. Using High-Definition (HD) endoscopy, gastroenterology experts can identify esophageal cancer at an early stage. Recent research shows that early cancer can be found using a state-of-the-art computer-aided detection (CADe) system based on analyzing static HD endoscopic images. Our research aims at extending this system by applying Random Forest (RF) classification, which introduces a confidence measure for detected cancer regions. To visualize this data, we propose a novel automated annotation system, employing the unique characteristics of the previous confidence measure. This approach allows reliable modeling of multi-expert knowledge and provides essential data for real-time video processing, to enable future use of the system in a clinical setting. The performance of the CADe system is evaluated on a 39-patient dataset, containing 100 images annotated by 5 expert gastroenterologists. The proposed system reaches a precision of 75% and recall of 90%, thereby improving the state-of-the-art results by 11 and 6 percentage points, respectively.

    Gastrointestinal complications are a frequent cause of morbidity after transplantation and may affect up to 40% of kidney transplant recipients. Here we report a rare case of idiopathic giant esophageal ulcer in a kidney transplant recipient. A 37-year-old female presented with a one-week history of odynophagia and weight loss. Upon admission, the patient presented cold sores, and a quantitative cytomegalovirus polymerase chain reaction was positive (10(5) copies/mL). An upper endoscopy demonstrated the presence of a giant ulcer. Serological test and tissue biopsies were unable to demonstrate an infectious origin of the ulcer. Immunosuppression was reduced and everolimus was introduced. An empirical i.v. therapy with acyclovir was started, resulting in a dramatic improvement in symptoms and complete healing of the ulcer. Only two cases of idiopathic giant esophageal ulcer in kidney transplant recipients have been reported in the literature; in both cases, steroid therapy was successful without recurrence of symptoms or endoscopic findings. However, this report suggests that correction of immune imbalance is mandatory to treat such a rare complication.

    Fifteen patients with locally advanced esophageal cancer were treated with phototherapy. Each patient had dysphagia and weight loss before therapy and could not be operated on because of the extent of the tumor or poor performance status. Patients received a photosensitizer (hematoporphyrin derivative) 72 hours before phototherapy and were then treated by light delivered by an argon pumped dye laser or gold metal vapor laser at powers up to 2.2 W and doses of 337 J/cm2. Fourteen patients received 24 treatments. The results were all patients achieved a tumor response. The depth of response depended on the dose and dose rate of radiation. There were four of 24 local complications (mediastinitis 3, bronchoesophageal fistula 1). These occurred in patients treated with a power of greater than 1.5 W. There were two complete pathologic remissions in patients with locally advanced cancer. In conclusion, phototherapy is an effective alternative to other forms of palliation and potentially may be an alternative to surgery in selected cases of locally advanced esophageal cancer.

    Studies of AMCase inhibition in mouse models of lung eosinophilic inflammation have produced conflicting results with some studies demonstrating inhibition of eosinophilic inflammation and others not. No studies have investigated the role of AMCase inhibition in eosinophilic esophagitis (EoE). We have used a mouse model of egg (OVA) induced EoE to determine whether pharmacologic inhibition of AMCase with allosamidin reduced eosinophilic inflammation and remodeling in the esophagus in EoE. Administration of intra-esophageal OVA for 6weeks to BALB/c mice induced increased levels of esophageal eosinophils, mast cells, and features of esophageal remodeling (fibrosis, basal zone hyperplasia, deposition of the extracellular matrix protein fibronectin). Administration of intraperitoneal (ip) allosamidin to BALB/c mice significantly inhibited AMCase enzymatic activity in the esophagus. Pharmacologic inhibition of AMCase with ip allosamidin inhibited both OVA induced increases in esophageal eosinophilic inflammation and OVA induced esophageal remodeling (fibrosis, epithelial basal zone hyperplasia, extracellular matrix deposition of fibronectin). This inhibition of eosinophilic inflammation in the esophagus by ip allosamidin was associated with reduced eotaxin-1 expression in the esophagus. Oral allosamidin inhibited eosinophilic inflammation in the epithelium but did not inhibit esophageal remodeling. These studies suggest that pharmacologic inhibition of AMCase results in inhibition of eosinophilic inflammation and remodeling in the esophagus in a mouse model of egg induced EoE partially through effects in the esophagus on reducing chemokines (i.e. eotaxin-1) implicated in the pathogenesis of EoE.

    Percutaneous transluminal angioplasty and stenting of carotid artery stenosis represents an innovative experimental modality which has been increasingly employed in high-risk patients. Currently, results from prospective randomized trials are not available; thus, guidelines with regard to indications and technique are preliminary. Numerous technical innovations to avoid associated complications have evolved in neurointerventional procedures. Dedicated guiding catheters and stents using a transfemoral approach have been introduced for treatment of carotid artery disease. Low-profile stent delivery systems may decrease risk of releasing embolic load when crossing high-grade stenosis or kinking of the vessel. The introduction of a cerebral protection with the use of temporary occlusion balloons or filter systems has resulted in a reduction of procedure-related neurological complications, and is strongly recommended by leading experts in the field.

    The ideal laser produces discrete wounds in a reproducible manner. The CO2 laser with its 10.6 micron wavelength is highly absorbed by water, its energy concentrated at the point of impact and the longer wavelength creates less scatter in tissue. The development of binocular endoscopic delivery system for use with binocular microlaryngoscopes have aided in using CO2 laser to treat patients with subglottic and tracheal stenosis. Often, patients with these disease processes require multiple endoscopic or open reconstructive procedures and my ultimately become tracheotomy dependent. The canine model of subglottic stenosis that has been develop allows testing of new agents as adjuncts to laser treatment. Mitomycin-C is an antibiotic with antitumor activity used in chemotherapy and also in ophthalmologic surgery due to its known inhibition of fibroblast proliferation. Current studies indicate this drug to have significant potential for improving our current management of this disease process.

    The coexistence of renal artery stenosis and pheochromocytoma has been recognized since 1958 and a total of 36 patients reported. This article provides an additional patient with an extra adrenal pheochromocytoma and fibrous bands constricting the left renal artery. Hypertension was confirmed to occur from both excess catecholamine production and hyperreninemia from the left kidney. Surgical removal of the functioning paraganglioma and correction of the renal artery stenosis restored the postoperative plasma catecholamine, renin, and blood pressure to normal. A literature review confirmed the coexistence of these two lesions but failed to provide a common etiology to explain the pathophysiology encountered. However, when the two diseases occur simultaneously, both must be diagnosed accurately and treated in a definitive manner. Images Figs. 1a and b. Figs. 2a and b. PMID:6830355

    Term infants with hypertrophic pyloric stenosis (HPS) typically present between 4 and 6 weeks. There is limited consensus, however, regarding age of presentation of premature infants. We aim to determine if there is an association between the degree of prematurity and chronological age of presentation of HPS. A total of 2988 infants who had undergone a pyloromyotomy for HPS were identified from the 2012 and 2013 NSQIP-P Participant Use Files. Two hundred seventeen infants (7.3%) were born prematurely. A greater degree of prematurity was associated with an older chronological age of presentation ( P < .0001). Prematurity was significantly associated with an increase in overall postoperative morbidity, reintubation, readmission, and postoperative length of stay. When clinicians evaluate an infant with nonbilious emesis with a history of prematurity, they should consider pyloric stenosis if the calculated postconceptional age is between 44 and 50 weeks. When counseling families of premature infants, surgeons should discuss the increased incidence of postpyloromyotomy morbidity.

    The maternal use of Bendectin (Debendox) in the first trimester of pregnancy was examined in a case-control (n = 1,427 and 3,001, respectively) study of malformed infants whose mothers were interviewed between 1974 and 1976. Mothers of infants with congenital malformation showed an increased likelihood (odds ratio = 1.40) of having used Bendectin, with a stronger association of Bendectin with birth defects for mothers who also smoked (odds ratio = 2.91). A significant association was observed between the occurrence of pyloric stenosis in the infant and exposure to Bendectin in utero (odds ratio = 4.33). When maternal sociodemographic factors, including smoking, and smoking alone, were controlled, the association between Bendectin and pyloric stenosis was further increased (odds ratio = 4.63 and 5.24, respectively). Except for a possible association of Bendectin with heart valve anomalies (odds ratio = 2.99), we were unable to document other significantly increased risks for congenital malformations.

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith–Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB. PMID:25871299

    A current thrust in medical research is the development of a non-invasive method for detection, localization, and characterization of an arterial stenosis (a blockage or partial blockage in an artery). A method has been proposed to detect shear waves in the chest cavity which have been generated by disturbances in the blood flow resulting from a stenosis. In order to develop this methodology further, we use one-dimensional shear wave experimental data from novel acoustic phantoms to validate a corresponding viscoelastic mathematical model. We estimate model parameters which give a good fit (in a sense to be precisely defined) to the experimental data, and use asymptotic error theory to provide confidence intervals for parameter estimates. Finally, since a robust error model is necessary for accurate parameter estimates and confidence analysis, we include a comparison of absolute and relative models for measurement error.

    To investigate whether abdominal scar characteristics could predict the occurrence of cervical stenosis after abdominal radical trachelectomy (ART), we conducted a retrospective study and investigated the relationship between abdominal scar characteristics and the occurrence of cervical stenosis in patients one year after undergoing ART. The abdominal scars were evaluated using the Vancouver Scar Scale (VSS). Seventy-two participants were enrolled in the study, including 15 (20.8%) women with cervical stenosis, and 57 (79.2%) without stenosis. Results showed that the mean abdominal scar score assessed by VSS was higher in patients with cervical stenosis (7, range: 1–10) compared to those without stenosis (4, range: 0–9) (P = 0.001). Incidence rates of cervical stenosis increased with the VSS score. For women with VSS scores of 0 to 4, 5, 6, 7, 8, 9 and 10, respectively, the occurrences of cervical stenosis were 6.1%, 16.7%, 16.7%, 27.3%, 37.5%, 50% and 100%. The cutoff point of VSS score was 7 according to the receiver operating characteristic (ROC) curve. Fourteen of the 15 stenosis happened either in patients without anti-stenosis tools (Foley catheters or tailed intrauterine devices) placed during the surgery or after the devices were removed. Our results demonstrated that VSS is an effective approach to assess the presence of cervical stenosis after ART. Women who have an abdominal scar with a VSS score > 7 have a high risk of developing isthmic stenosis without anti-stenosis tools in place. PMID:27191256

    The usual presentation of anomalous left coronary artery from pulmonary artery is severe left-sided heart failure and mitral valve insufficiency presenting during the first months of life. The manifestations of left heart failure may be masked if pulmonary artery pressure remains high. We believe this is a rarest of rare case of anomalous left coronary artery from pulmonary artery with severe mitral stenosis and pulmonary hypertension in which pulmonary hypertension, along with good collateral circulation helped to preserve left ventricular function.

    Guidelines recommend the use of ultrasound dilution techniques (UDT), including measurement of access recirculation (AR) and access blood flow (Q(a)), to screen for subclinical vascular access dysfunction. Although these techniques are efficacious in polytetrafluoroethylene grafts, data in native vessel arteriovenous fistulae (AVF) are lacking. A prospective observational study was conducted to evaluate the utility of UDT screening in AVF. Q(a) and AR were measured bimonthly. Positive studies required fistulograms and were defined by Q(a) < 500 ml/min, DeltaQ(a) > 20% from baseline or AR > 5%. Accesses with stenosis underwent percutaneous angioplasty. After 1 yr, there were 1355 mo of follow-up in 177 patients. There were 44 positive studies in 40 patients. Q(a) was <500 ml/min in 36 (82%), DeltaQ(a) was >20% in 5 (11%), and AR was >5% in 6 (14%). Of patients with Q(a) < 500 ml/min, 29 (81%) had stenosis. Only two patients (40%) with DeltaQ(a) > 20% but Q(a) > 500 ml/min had stenosis. No patient with AR > 5% had stenosis unless Q(a) was also <500 ml/min. Immediate patency rate was 93% post-PTA. Mean Q(a) increased from 303 +/- 154 ml/min to 602 +/- 220 ml/min (P < 0.0001), and mean urea reduction ratio increased from 70.4 +/- 8.4% to 74.6 +/- 6.5% (P = 0.003) post-PTA. The results demonstrate that UDT could detect subclinical stenoses in AVF, and most lesions were amenable to angioplasty. AVF that underwent PTA delivered higher Q(a) and urea reduction ratio, and immediate patency rates were acceptable. Access failure after negative UDT was unusual. Measuring AR increases the time required to perform UDT but does not improve utility. Serial measurements of Q(a) alone may be the best strategy for screening AVF.

    The Wernicke-Korsakoff syndrome (WKS) is a picture of oculomotor alterations, ataxia and confusion presented in chronic alcoholics. It has more rarely been described in non alcoholic patients with malnutrition. The case of a patient with ulcerous peptic disease of long evolution who consulted for a picture compatible with WKS following clinical manifestations of repeated vomiting secondary to complete pyloric stenosis is presented. The peculiarity of the picture and the convenience of prevention in malnourished patients receiving intravenous glucose sera is discussed.

    The case histories of five adult patients with hydrocephalus and aqueduct stenosis are presented. All the cases were associated with prominent psychotic symptoms (delusions, hallucinations or thought disorder). In the three cases where operative intervention was carried out the diagnosis was made in adult life. Using the Present State Examination all five cases were classified as having schizophrenic psychosis. The possible reasons for this association are discussed. PMID:6644313

    The management of atherosclerotic renal artery stenosis (ARAS) in patients with hypertension has been the topic of great controversy. Major contemporary clinical trials such as the Cardiovascular Outcomes for Renal Artery lesions (CORAL) and Angioplasty and Stenting for Renal Atherosclerotic lesions (ASTRAL) have failed to show significant benefit of revascularization over medical management in controlling blood pressure and preserving renal function. We present here the implications and limitations of these trials and formulate recommendations for management of ARAS.

    Transluminal angioplasty (TLA) has been used in six patients with subclavian artery stenosis admitted to a large community hospital. Five patients had lesions proximal to the origin of the left vertebral artery, three of whom had angiographic evidence of subclavian steal syndrome. In all six, arteries were successfully dilated with only one complication of a hematoma at an arteriotomy site. In a 10 to 24-month follow-up, all six patients have remained totally asymptomatic without any further complications.

    A 69 +/- 5% stenosis was produced in the rat aorta, with the purpose of correlating endothelial changes with local flow patterns and with levels of shear stress; the hydrodynamic data were obtained from a scaled-up model of the stenosed aorta. In the throat of the stenosis, where shear stress values were 15-25 times normal, the endothelium was stripped off within 1 hour. It regenerated at half the rate of controls but modulated into a cell type that could withstand the increased shear stress. Adaptations included changes in cell orientation, number, length, width, thickness, stress fibers, and anchoring structures, as well as changes in the length, argyrophilia, and permeability of the junctions. Areas of either elongated or "polygonal" cells consistently developed at the same sites in relation to the stenosis, but the hydrodynamic data showed that they did not always correspond (as had been anticipated) to high and low shear, respectively. It is concluded that endothelial cell shape in the living artery must be determined by some other factor(s) in addition to shear stress.

    Transplant renal artery stenosis (TRAS) is a well-recognized vascular complication after kidney transplant. It occurs most frequently in the first 6 months after kidney transplant, and is one of the major causes of graft loss and premature death in transplant recipients. Renal hypoperfusion occurring in TRAS results in activation of the renin-angiotensin-aldosterone system; patients usually present with worsening or refractory hypertension, fluid retention and often allograft dysfunction. Flash pulmonary edema can develop in patients with critical bilateral renal artery stenosis or renal artery stenosis in a solitary kidney, and this unique clinical entity has been named Pickering Syndrome. Prompt diagnosis and treatment of TRAS can prevent allograft damage and systemic sequelae. Duplex sonography is the most commonly used screening tool, whereas angiography provides the definitive diagnosis. Percutaneous transluminal angioplasty with stent placement can be performed during angiography if a lesion is identified, and it is generally the first-line therapy for TRAS. However, there is no randomized controlled trial examining the efficacy and safety of percutaneous transluminal angioplasty compared with medical therapy alone or surgical intervention.

    The aim of this prospective study was to characterise patient characteristics and the histories of cats with acquired nasopharyngeal stenosis (ANS), and to describe the use of a removable silicone stent for treatment. ANS was diagnosed in 15 cats with clinical signs present for a median of 4 months. Clinical signs included stertor and inspiratory difficulty, nasal discharge, sneezing, dysphagia, regurgitation, vomiting and anorexia. Radiographs revealed a dorsal deviation or deformation of the caudal part of the soft palate in 10 of the cats, a soft tissue density across the cranial nasopharynx in four and no abnormality in one. The stenosis was initially dilated with a Kelly forceps in 10 of the cats and by balloon dilatation in five. A segment of a 24 Fr silicone thoracic catheter was used for the stent in five cats; in the other 10 cats a segment of a 28 Fr catheter was used. The stent was removed after 3 weeks in 12 cats and after 4 weeks in the other three. Endoscopy revealed an adequate nasopharyngeal diameter in all of the cats. At both 3 and 10 months after surgery the response was considered to be satisfactory, with complete resolution of clinical signs in 14 cats and improvement in the remaining cat. The treatment of ANS by stenosis dilatation followed by temporary stenting with a silicone stent is a rapid, safe, economical and effective procedure.

    The aim of the present study was to comprehensively evaluate the clinical features and long-term outcomes of congenital aural stenosis (CAS). This study presents a retrospective review of patients who underwent meatoplasty for CAS at a tertiary referral hospital from 2008 to 2015. A total of 246 meatoplasty procedures were performed on 232 patients in the present study. We performed multivariate regression analysis. Except in the age < 6 years group, no significant difference was observed among different age groups for cholesteatoma formation, p > 0.05. Except for the stenosis of the external auditory canal (EAC) (>4 mm) group, the other stenosis of EAC groups were not associated with cholesteatoma formation, p > 0.05. Postoperative air-bone gaps (ABG) less than 30 dB occurred in 77.3% (99/128) of the patients, and the Jahrsdoerfer score was associated with postoperative ABG, p < 0.001. The complication rate of CAS was 13.8% (20/144), and males showed a higher risk for postoperative complications (OR, 6.563; 95% CI, 1.268–33.966, p = 0.025). These results indicate that meatoplasty was an effective surgical intervention for CAS, showing a stable hearing outcome with prolonged follow-up. There was no significant difference between the cholesteatoma and no cholesteatoma groups for hearing outcomes, p > 0.05. PMID:27257165

  4. Mechanical behavior of the erythrocyte in microvessel stenosis.

    The passage of red blood cells (RBCs) through capillaries is essential for human blood microcirculation. This study used a moving mesh technology that incorporated leader-follower pairs to simulate the fluid-structure and structure-structure interactions between the RBC and a microvessel stenosis. The numerical model consisted of plasma, cytoplasm, the erythrocyte membrane, and the microvessel stenosis. Computational results showed that the rheology of the RBC is affected by the Reynolds number of the plasma flow as well as the surface-to-volume ratio of the erythrocyte. At a constant inlet flow rate, an increased plasma viscosity will improve the transit of the RBC through the microvessel stenosis. For the above reasons, we consider that the decreased hemorheology in microvessels in a pathological state may primarily be attributed to an increase in the number of white blood cells. This leads to the aggregation of RBCs and a change in the blood flow structure. The present fundamental study of hemorheology aimed at providing theoretical guidelines for clinical hemorheology.

    A 6-month-old German shepherd dog was referred for evaluation of a cardiac murmur. Upon physical examination, the auscultated heart rate was 120 beats/min, and a grade IV/VI systolic heart murmur with a point of maximal intensity over the left heart base radiating up the neck was heard. The standard echocardiographic examination showed subaortic stenosis and an anechoic tubular structure extending from the sinus of Valsalva to the left ventricular posterior wall. Aneurysmal left coronary artery (CA) was confirmed by angiography. The dog was euthanized and post-mortem examination showed severe dilatation of the proximal left CA and confirmed the subaortic stenosis. Histopathology did not demonstrate abnormalities in the walls of the CA, aorta or pulmonary artery. The exact cause of the CA aneurysmal dilation remains unknown. Subaortic stenosis, elevated coronary vascular resistance or a congenital anomaly may have contributed to the dilation. To our knowledge, coronary aneurysmal dilation has never been described in dogs. Standard echocardiography provides reliable information on coronary anatomy.

    Esophagitis dissecans superficialis (EDS) is a rare desquamative disorder of the esophagus. It is characterized by sheets of sloughed squamous tissue with normal underlying mucosa. We present a case of a 68-year-old man with severe anemia and a positive fecal occult blood test who was found to have features suggestive of EDS during endoscopy. However, histological features were suggestive of both EDS and fungal esophagitis. To our knowledge, this is the first reported case in literature which discusses the clinical scenario of fungal infection being a possible etiology rather than a commonly accepted differential diagnosis of EDS. We also review the clinical features, diagnostic criteria and treatment of EDS. PMID:28058081

    Trisomy 18 is one of the congenital disorders caused by a chromosomal abnormality. Ninety percent of fetuses with trisomy 18 have various other malformations. The present patient had heart failure due to a complex cardiac malformation and a Gross C type esophageal atresia. Before the esophageal banding, ventilation of the lungs was impossible and respiratory condition was unstable. Considering that direction of the shunt can easily change by hyperventilation and high oxygen concentration, we employed the lowest oxygen concentration and ventilation as possible. In the present case, it was necessary to provide respiratory care for both esophageal atresia and complex cardiac malformation.

    Patients with eosinophilic esophagitis (EoE) undergo multiple endoscopies with biopsy for both diagnosis and assessment of treatment response, which is inconvenient and costly. Brush cytology has been examined in Barrett's esophagus to reduce the need for repeated endoscopic biopsies. The aim of this pilot study was to evaluate the ability of brush cytology to detect mucosal eosinophilia in patients with EoE. This prospective study included adults with untreated and treated esophageal eosinophilia undergoing endoscopy at a tertiary care center. Patients received paired brushings and biopsies at the proximal and distal esophagus. A blinded pathologist quantified the number of eosinophils and epithelial cells per high-power field (hpf) on the cytology slides. The ratio of eosinophils/epithelial cells was used to normalize the cytology specimens for density of cells collected. The main outcome measures were sensitivity and specificity of brush cytology, and correlation between cytology and histology. Twenty-eight patients enrolled. The average age of the cohort was 37.7 ± 10.4 years; 75% of subjects were male. The sensitivity of cytology was 67-69% at the proximal esophagus and 70-72% at the distal esophagus. The specificity was 61-67% proximally and 70-75% distally. Histology was not significantly correlated with the max ratio of eosinophils/epithelial cells per hpf or the absolute number of eosinophils on cytology slides. Cytology using esophageal brushing has limited sensitivity and specificity for the detection of esophageal mucosal eosinophilia. The presence of exudates on endoscopy increased the detection of eosinophilia, which could make cytology useful in pediatric EoE, which often has a more exudative presentation. Diagnostic yield may improve with alternative acquisition techniques or the incorporation of eosinophil degranulation proteins.

  9. From reflux esophagitis to Barrett’s esophagus and esophageal adenocarcinoma

    2015-01-01

    The occurrence of gastroesophageal reflux disease is common in the human population. Almost all cases of esophageal adenocarcinoma are derived from Barrett’s esophagus, which is a complication of esophageal adenocarcinoma precancerous lesions. Chronic exposure of the esophagus to gastroduodenal intestinal fluid is an important determinant factor in the development of Barrett’s esophagus. The replacement of normal squamous epithelium with specific columnar epithelium in the lower esophagus induced by the chronic exposure to gastroduodenal fluid could lead to intestinal metaplasia, which is closely associated with the development of esophageal adenocarcinoma. However, the exact mechanism of injury is not completely understood. Various animal models of the developmental mechanisms of disease, and theoretical and clinical effects of drug treatment have been widely used in research. Recently, animal models employed in studies on gastroesophageal reflux injury have allowed significant progress. The advantage of using animal models lies in the ability to accurately control the experimental conditions for better evaluation of results. In this article, various modeling methods are reviewed, with discussion of the major findings on the developmental mechanism of Barrett’s esophagus, which should help to develop better prevention and treatment strategies for Barrett’s esophagus.

The relationship between the simptoms and the clinical procedures done in the patients were observed as was the usefulness of esophagic manometry to detect not only the direct pressure of the gastro-esophagic sphincter, but also to determine the concurrent motor changes that can occur in patients which show hiatal hernia. The benefit of this studies to decide the therapeutic handling, specially surgical, is discussed.

    Gastro-esophageal reflux disease (GERD) is the most common digestive disease in industrialized countries (Europe and North America) and is associated with microscopic changes in the squamous epithelium. However, biopsy is not presently included in the routine diagnostic flow chart of GERD. In contrast, esophageal biopsy is mandatory when diagnosing Barrett's esophagus. High quality histology reports are necessary to provide information on diagnosis and can also be important for research and epidemiological studies. It has been evident for decades that pathology reports vary between institutions and even within a single institution. Standardization of reporting is the best way to ensure that information necessary for patient management is included in pathology reports. This paper details the histological criteria for diagnosing GERD-associated microscopic esophagitis, other forms of esophagitis with specific features and columnar metaplasia in the lower esophagus (Barrett's esophagus). It provides a detailed description of appropriate sampling criteria, individual lesions and how they contribute to the histology report.

    Patients with impacted esophageal foreign bodies usually present with gastrointestinal and rarely with respiratory symptoms. Impacted esophageal foreign bodies may be identified by radiologic studies. Ingested radiolucent foreign bodies may be more difficult to diagnose, especially if the patient presents with minimal symptoms. We report a rare case of a child who presented with stridor and obstructive sleep apnea. The cause of respiratory symptoms was thought to be due to enlarged tonsils and adenoids, and the patient was scheduled for tonsillectomy and adenoidectomy. On re-evaluation by the surgeon on the day of surgery, the procedure was changed to diagnostic microlaryngoscopy and bronchoscopy to rule out any other cause. The patient's respiratory symptoms were resolved when an incidental discovery and retrieval of the radiolucent esophageal foreign body was made. The diagnosis of radiolucent esophageal foreign body can be difficult and can be easily missed without reasonable clinical suspicion.

    Esophageal candidiasis is one of the most common opportunistic infections in patients infected by human immunodeficiency virus (HIV). This pathology is also found in patients without overt immunodeficiency. Other risk factors are known to be associated with this disease like inhaled or systemic corticosteroid treatment or proton-pump inhibitors and H2 receptor antagonists. In the absence of identified risk factors, a primary immune deficiency should be sought. Prevention of esophageal candidiasis is based primarily on the identification of risk factors, and a better control of them. This article presents a review of the physiopathology, clinical presentation and management of esophageal candidiasis by primary care physicians. We will also discuss ways of preventing esophageal candidiasis when necessary.

    1992-01-01

    Esophageal voice obtained through logopedic treatment and speech produced by electronic prostheses is the principal means of verbal communication of laryngectomized patients. Several factors condition the success of logopedic rehabilitation: entity of hypopharyngeal surgical exeresis and scar repairing modalities; rehabilitation technique employed; patient's skill in controlling pharyngo-esophageal tract and articulation organs; patient motivation. A previous study executed by our School reported that only the 20% of the patients who did not practise logopedic therapy employed the laryngophone. Reduced use of electronic prosthesis depends on three factors: acoustic products of poor quality; evidence of anatomic and functional impairment pointed out by laryngophone use; limitation of manual activity during phonation. Electronic prostheses have a precise indication in the following cases: immediately after surgery; in case of logopedic treatment failure and when tracheo-esophageal prosthesis are contraindicated; when the esophageal voice has an insufficient volume or in noisy environments. Finally indicative criteria to introduce patients to the most suitable rehabilitation modality are reported.

    Esophageal cancer is a lethal cancer encompassing adenocarcinoma and squamous cell carcinoma sub-types. The global incidence of esophageal cancer is increasing world-wide, associated with the increased prevalence of associated risk factors. The asymptomatic nature of disease often leads to late diagnosis and five-year survival rates of less than 15%. Current diagnostic tools are restricted to invasive and costly endoscopy and biopsy for histopathology. Minimally and non-invasive biomarkers of esophageal cancer are needed to facilitate earlier detection and better clinical management of patients. This paper summarises recent insights into the development and clinical validation of esophageal cancer biomarkers, focussing on circulating markers in the blood, and the emerging area of breath and odorant biomarkers.

    Esophageal motility has been well studied in gastroesophageal reflux disease (GERD) and acid reflux, but not in nonacid reflux. Consecutive patients who had both 24-h multichannel intraluminal impedance-pH (MII-pH) and esophageal motility tests for suspected GERD were studied. Patients were grouped into nonacid refluxers, acid refluxers, and nonrefluxers based on positive symptom correlation and objective findings of acid reflux. Of 96 patients enrolled, 21 patients (22%) were nonacid refluxers, 44 patients (46%) were acid refluxers, and 31 patients (32%) had no objective evidence of reflux. Normal motility was recorded in 86% of nonacid refluxers, 71% of acid refluxers, and 60% of nonrefluxers. Ineffective esophageal motility was seen in 24% of acid refluxers, and 5% of nonacid refluxers (P = 0.11). Symptomatic nonacid reflux events comprised 22% of patients studied for GERD symptoms by MII-pH. Esophageal motility in nonacid reflux is normal 86% of the time.

    About 1500 high-risk subjects of esophageal cancer were found during screening by balloon cytology and all of them were examined endoscopically. Among them, 120 were considered as having early esophageal cancer and precancerous lesions. During the examination, Lugol's solution staining was used and guiding biopsy was taken. 98 subjects with unstained lesions were found, and biopsy showed early esophageal cancer in 60 (61.2%) and moderate and severe dysplasia in 38 (38.8%). It is usually extremely difficult to detect and localize the very early esophageal mucosal and submucosal carcinoma. But endoscopic examination and using Lugol's solution staining with multiple spots biopsy from unstained area are of great assistance. Minute malignant lesions may not be overlooked.

    Ineffective esophageal motility (IEM) is the most frequently encountered esophageal motility disorder. Patients may present with a variety of symptoms, such as dysphagia, heartburn, odynophagia, and regurgitation. Over the past years, the landscape of esophageal motility testing has been revolutionized; however, our current treatment options for IEM still remain limited. Previous studies have suggested that buspirone, a serotonin receptor agonist, enhances esophageal peristalsis and lower esophageal sphincter (LES) function. Recent work provides the first evidence that buspirone may influence LES resting pressure in patients with systemic sclerosis. Future research should evaluate whether the beneficial effects of buspirone also apply to the broad clinical entity of esophageal dysphagia patients with IEM.

    Biliary stenosis is a common complication after liver transplantation, and has an incidence rate ranging from 4.7% to 12.5% based on our previous study. Three types of biliary stenosis (anastomotic stenosis, non-anastomotic peripheral stenosis and non-anastomotic central hilar stenosis) have been identified. We report the outcome of two patients with anastomotic stricture after liver transplantation who underwent successful cutting balloon treatment. Case 1 was a 40-year-old male transplanted due to subacute fulminant hepatitis C. Case 2 was a 57-year-old male transplanted due to hepatitis B virus-related end-stage cirrhosis associated with hepatocellular carcinoma. Both patients had similar clinical scenarios: refractory anastomotic stenosis after orthotopic liver transplantation and failure of balloon dilation of the common bile duct to alleviate biliary stricture.

  4. Viewpoints on Acid-Induced Inflammatory Mediators in Esophageal Mucosa

    PubMed Central

    Harnett, Karen M; Rieder, Florian; Behar, Jose

    2010-01-01

    We have focused on understanding the onset of gastroesophageal reflux disease by examining the mucosal response to the presence of acid in the esophageal lumen. Upon exposure to HCl, inflammation of the esophagus begins with activation of the transient receptor potential channel vanilloid subfamily member-1 (TRPV1) in the mucosa, and production of IL-8, substance P (SP), calcitonin gene related peptide (CGRP) and platelet activating factor (PAF). Production of SP and CGRP, but not PAF, is abolished by the neural blocker tetrodotoxin suggesting that SP and CGRP are neurally released and that PAF arises from non neural pathways. Epithelial cells contain TRPV1 receptor mRNA and protein and respond to HCl and to the TRPV1 agonist capsaicin with production of PAF. PAF, SP and IL-8 act as chemokines, inducing migration of peripheral blood leukocytes. PAF and SP activate peripheral blood leukocytes inducing the production of H2O2. In circular muscle, PAF causes production of IL-6, and IL-6 causes production of additional H2O2, through activation of reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidases. Among these, NADPH oxidase 5 cDNA is significantly up-regulated by exposure to PAF; H2O2 content of esophageal and lower esophageal sphincter circular muscle is elevated in human esophagitis, causing dysfunction of esophageal circular muscle contraction and reduction in esophageal sphincter tone. Thus esophageal keratinocytes, that constitute the first barrier to the refluxate, may also serve as the initiating cell type in esophageal inflammation, secreting inflammatory mediators and pro-inflammatory cytokines and affecting leukocyte recruitment and activity.

    AIM: To study, whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology. METHODS: From 1987 until 2007, all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed. All of them underwent structured interviews with regards to clinical symptoms, as well as endoscopic and/or radiographic examinations. Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities. RESULTS: One hundred and sixty-seven patients (125 male, 42 female) with a mean age of 57.1 ± 14.6 years were studied. All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction. Patients experienced symptoms for a mean of 4.7 ± 5.2 years before diagnosis. Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic, was the SR previously diagnosed. At presentation, the mean ring diameter was 13.9 ± 4.97 mm. One hundred and sixty-two (97%) patients showed a sliding hiatal hernia. Erosive reflux esophagitis was found in 47 (28.1%) patients. Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs; five (3.0%) patients exhibited eosinophilic esophagitis; and four (2.4%) had esophageal diverticula. Four (7%) of 57 patients undergoing esophageal manometry had non-specific esophageal motility disorders. CONCLUSION: Schatzki rings are frequently associated with additional esophageal disorders, which support the assumption of a multifactorial etiology. Despite typical symptoms, SRs might be overlooked. PMID:21734791

    Significant disparities exist between genders for the development and progression of several gastro-intestinal (GI) diseases including cancer. Differences in incidence between men vs women for colon, gastric and hepatocellular cancers suggest a role for steroid sex hormones in regulation of GI carcinogenesis. Involvement of intrinsic gender-linked mechanisms is also possible for esophageal adenocarcinoma as its incidence is disproportionally high among men. However, the cause of the observed gender differences and the potential role of androgens in esophageal carcinogenesis remains unclear, even though the cancer-promoting role of androgen receptors (AR) shown in other cancers such as prostate and bladder suggests this aspect warrants exploration. Several studies have demonstrated expression of ARs in esophageal cancer. However, only one study has suggested a potential link between AR signaling and outcome - poorer prognosis. Two groups have analyzed data from cohorts with prostate cancer and one of these found a decreased incidence of esophageal squamous and adenocarcinoma after androgen deprivation therapy. However, very limited information is available about the effects of androgen and AR-initiated signaling on esophageal cancer cell growth in vitro and in vivo. Possible mechanisms for androgens/AR involvement in the regulation of esophageal cancer growth are considered, and the potential use of AR as a prognostic factor and clinical target is highlighted, although insufficient evidence is available to support clinical trials of novel therapies. As esophageal adenocarcinoma is a gender linked cancer with a large male predominance further studies are warranted to clarify the role of androgens and ARs in shaping intracellular signaling and genomic responses in esophageal cancer.

    The author collects the data of esophageal cancer mortality (1971-1973) of 78 counties in Hubei Province and the data of topography, climate, soil, rock formation and geochemical elements, including 40 suspected factors. The method of linear correlation and multiple stepwise regression are used for the comprehensive analysis of relation between the geographical factors and esophageal cancer. The result is that four factors metamorphic rock, zinc, copper, chromium are suspected factors. It suggests that the four factors will need future study.

    Background Esophageal/gastroesophageal junction (GEJ) adenocarcinoma is increasingly treated with trimodality therapy. We present our experience using carboplatin/paclitaxel and radiotherapy followed by surgery. Methods Consecutive patients with distal esophageal/GEJ adenocarcinoma (≥T2 or N+) treated from July 2010 to October 2011 were identified. Treatment included neoadjuvant carboplatin/paclitaxel with concurrent radiotherapy (CRT) to 50.4 Gy using an IMRT technique and then Ivor Lewis esophagogastrectomy (ILE). PET/CT was performed prior to and after CRT. Patient/treatment characteristics and tumor response were analyzed. Results Over this timeframe, 16 patients completed trimodality therapy. All were male, median age of 60 years (45-72 years). All tumors were grade 2-3 with mean tumor length of 4.4 cm (1-9 cm). A median of 6 cycles (5-9 cycles) neoadjuvant carboplatin/paclitaxel were administered. Average time from diagnosis to CRT completion was 76 days (44-141 days) and 60 days (35-92 days) from CRT end to surgery. Neoadjuvant CRT was well tolerated with mean weight loss of 3.9 kg. All pts had R0 resections. No anastomotic leaks or perioperative mortality occurred. Mean hospital stay was 13 days (8-28 days). Pathologic complete response (pCR) was seen in 38% of patients, microscopic residual disease (isolated tumor cells or <2 mm) in 31%, and macroscopic residual disease remained in 31%. Mean SUV reduction was 41% (0-100%). Of 11 patients with ≥35% SUV decrease, 45% had pCR and 27% had microscopic residual disease. Three patients had signet ring features. Of these, 2 had no SUV reduction and all had gross residual disease, including the only patient with positive nodal disease. Conclusions Trimodality therapy utilizing concurrent carboplatin/paclitaxel and radiotherapy to 50.4 Gy followed by surgery was well tolerated and resulted in significant pathologic complete response or minimal residual disease.

    Esophageal cancer (EC) is one of the most common malignancies in low- and medium-income countries and represents a disease of public health importance because of its poor prognosis and high mortality rate in these regions. The striking variation in the prevalence of EC among different ethnic groups suggests a significant contribution of population-specific environmental and dietary factors to susceptibility to the disease. Although individuals within a demarcated geographical area are exposed to the same environment and share similar dietary habits, not all of them will develop the disease; thus genetic susceptibility to environmental risk factors may play a key role in the development of EC. A wide range of xenobiotic-metabolizing enzymes are responsible for the metabolism of carcinogens introduced via the diet or inhaled from the environment. Such dietary or environmental carcinogens can bind to DNA, resulting in mutations that may lead to carcinogenesis. Genes involved in the biosynthesis of these enzymes are all subject to genetic polymorphisms that can lead to altered expression or activity of the encoded proteins. Genetic polymorphisms may, therefore, act as molecular biomarkers that can provide important predictive information about carcinogenesis. The aim of this review is to discuss our current knowledge on the genetic risk factors associated with the development of EC in different populations; it addresses mainly the topics of genetic polymorphisms, gene-environment interactions, and carcinogenesis. We have reviewed the published data on genetic polymorphisms of enzymes involved in the metabolism of xenobiotics and discuss some of the potential gene-environment interactions underlying esophageal carcinogenesis. The main enzymes discussed in this review are the glutathione S-transferases (GSTs), N-acetyltransferases (NATs), cytochrome P450s (CYPs), sulfotransferases (SULTs), UDP-glucuronosyltransferases (UGTs), and epoxide hydrolases (EHs), all of which

    he occurrence of esophageal and gastric motor dysfunctions happens, when the software of the esophagus and the stomach is injured. This is really a program previously established in the enteric nervous system as a constituent of the newly called neurogastroenterology. The enteric nervous system is composed of small aggregations of nerve cells, enteric ganglia, the neural connections between these ganglia, and nerve fibers that supply effectors tissues, including the muscle of the gut wall. The wide range of enteric neuropathies that includes esophageal achalasia and gastroparesis highlights the importance of the enteric nervous system. A classification of functional gastrointestinal disorders based on symptoms has received attention. However, a classification based solely in symptoms and consensus may lack an integral approach of disease. As an alternative to the Rome classification, an international working team in Bangkok presented a classification of motility disorders as a physiology-based diagnosis. Besides, the Chicago Classification of esophageal motility was developed to facilitate the interpretation of clinical high-resolution esophageal pressure topography studies. This review covers exclusively the medical and surgical management of the esophageal and gastric motor dysfunction using evidence from well-designed studies. Motor control of the esophagus and the stomach, motor esophageal and gastric alterations, treatment failure, side effects of PPIs, overlap of gastrointestinal symptoms, predictors of treatment, burden of GERD medical management, data related to conservative treatment vs. antireflux surgery, and postsurgical esophagus and gastric motor dysfunction are also taken into account.

    Biologic scaffolds composed of extracellular matrix (ECM) have been used to facilitate repair or remodeling of numerous tissues, including the esophagus. The theoretically ideal scaffold for tissue repair is the ECM derived from the particular tissue to be treated, that is, site-specific or homologous ECM. The preference or potential advantage for the use of site-specific ECM remains unknown in the esophageal location. The objective of the present study was to characterize the in vitro cellular response and in vivo host response to a homologous esophageal ECM (eECM) versus nonhomologous ECMs derived from small intestinal submucosa and urinary bladder. The in vitro response of esophageal stem cells was characterized by migration, proliferation, and three-dimensional (3D) organoid formation assays. The in vivo remodeling response was evaluated in a rat model of esophageal mucosal resection. Results of the study showed that the eECM retains favorable tissue-specific characteristics that enhance the migration of esophageal stem cells and supports the formation of 3D organoids to a greater extent than heterologous ECMs. Implantation of eECM facilitates the remodeling of esophageal mucosa following mucosal resection, but no distinct advantage versus heterologous ECM could be identified.

    In general, the treatment methods for esophageal achalasia are largely classified into four groups, including drug therapy using nitrite or a calcium channel blocker, botulinum toxin injection, endoscopic therapy such as endoscopic balloon dilation, and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913, but the most common approach has changed from open-chest surgery to laparoscopic surgery. Currently, the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy, to thoracoscopic surgery, and to laparoscopic surgery, the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux, but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently, a new endoscopic approach, peroral endoscopic myotomy (POEM), has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.

    The technique of esophageal scintigraphy was developed as a sensitive, quantitative, noninvasive test of esophageal transit. Esophageal scintigraphy was performed in 40 asymptomatic normal volunteers in order to determine the effect on esophageal transit of the following: body posture (sitting vs. supine), liquid vs. solid, the solid being either a standard number4 gelatin capsule of the size used for antibiotic capsules, or a cube of solid food such as cooked chicken liver. The results showed that liquids emptied completely from the esophagus after one swallow, whether supine or sitting. Capsules or liver cubes, when ingested without water, frequently remained in the esophagus for up to two hours without the subject's having any sensation that the solid had not left the esophagus. Both capsules and liver cubes cleared the esophagus better in the upright than in the supine position. When gelatin capsules were swallowed with as little as 15 ml of water, but after a preliminary sip of water, there was complete transit in each case. The study suggests that the practice of assisting patients into a sitting position and instructing them to take a sip of water before attempting to swallow a capsule will assure better transit of the capsule even when swallowed with as little as 15 ml of water. This may reduce the incidence of esophagitis following oral antibiotics, and of esophageal erosions from aspirin-containing medications.

    Bariatric surgery has come to the forefront of weight loss treatment due to its complex interactions via anatomic, physiologic, and neurohormonal changes leading to sustained weight loss. Unlike lifestyle and pharmacologic options, which fail to show long-term sustained weight loss, bariatric surgery has been shown to decrease overall mortality and morbidity. Bariatric surgery can be purely restrictive, such as laparoscopic adjustable gastric band (LAGB) or laparoscopic sleeve gastrectomy (LSG), or restrictive-malabsorptive, such as Roux-en-Y gastric bypass (RYGB). These surgeries cause specific anatomic changes that promote weight loss; however, they also have unintended effects on the esophagus, particularly in terms of gastroesophageal reflux disease (GERD) and esophageal motility. Via restrictive surgery, LAGB has been widely reported to cause significant weight loss, although studies have also shown an increase and worsening of GERD as well as elevated rates of esophageal dilation, aperistalsis, and alterations in lower esophageal sphincter pressure. Along with LAGB, LSG has shown not only a worsening of GERD, but also the formation of de novo GERD in patients who were asymptomatic before the operation. In a restrictive-malabsorptive approach, RYGB has been reported to improve GERD and preserve esophageal motility. Bariatric surgery is a burgeoning field with immense implications on overall mortality. Future randomized, controlled trials are needed to better understand which patients should undergo particular surgeries, with greater emphasis on esophageal health and prevention of GERD and esophageal dysmotility.

    ABSTRACT Objective: To describe the clinical picture, test results, and clinical evolution of patients with cerebral palsy associated with diagnosis of eosinophilic esophagitis, monitored at tertiary centre. Methods: Cross-sectional, retrospective and descriptive study that evaluated the medical records data of pediatric patients with diagnosis of cerebral palsy and eosinophilic esophagitis in a tertiary center of pediatric gastroenterology between August 2005 and August 2013. Results: Seven out of 131 patients with cerebral palsy had the diagnosis of eosinophilic esophagitis. The mean age at diagnosis of eosinophilic esophagitis was 52.3 months and the mean number of eosinophils in esophagus was 35 per high-power field. Symptoms more frequent were recurrent vomiting and disphagia. Endoscopic alterations found were mucosal thickening, vertical lines, mucosal opacificacion and white plaques. Conclusion: The frequency of eosinophilic esophagitis found was higher than in general pediatric population. The investigation of eosinophilic esophagitis should be done regularly in those patients, once this entity could overlap other gastrointestinal diseases. PMID:26154544

    Abstract Esophageal varices is one of the most important comorbidity related liver cirrhosis, patients usually presented with hematemesis, melena, or both, ultimately 20% is the mortality during the first attack, hence we aimed to investigate the incidence of such esophageal varices related chronic Hepatitis C virus (HCV) in randomized Egyptian population. One thousand eighteen Egyptian patients, aged between 17 and 58 years, positive for Hepatitis C virus genotype 4 (HCV-4) by enzyme linked immunosorbent assay Ab and HCV RNA-polymerase chain reaction were screened for the presence of esophageal varices. Incidence of esophageal varices was 62.3%; 635 patients, those with large Esophageal varices (LEVs) was 47.4%; 301 patients. Model for end-stage liver disease (MELD) score has not been significantly improved post variceal band ligation (VBL). Using 2D U/S was useful for EVs prediction. Incidence of esophageal varices in HCV Egyptian patients still high, valuable knowledge would be helpful in clinical field have been discovered by data mining computational intelligent analysis using in practical medicine to improve overall health care.

    Compression of the upper cervical spinal cord due to stenosis of the bony spinal canal is infrequent. In the first case reported here, stenosis was due to acquired extensive, unilateral osteophytes centered on the left apophyseal joints of C1-C2 in an elderly professional violinist. In the second case, stenosis was secondary to isolated congenital hypertrophy of the laminae of C1 and C2.

    Background Debate over revascularization of asymptomatic carotid stenosis before cardiac surgery is ongoing. In this study, we analyze cardiac surgery outcomes in patients with asymptomatic carotid stenosis at a single hospital. Methods In this study, 1,781 patients underwent cardiac surgery from January 2012 to June 2013; 1,357 with preoperative screening carotid duplex were included. Patient demographics, comorbidities, degree of stenosis, postoperative complications, and mortality were evaluated. Chi-square test and logistic regression analysis were performed. Results Asymptomatic stenosis was found in 403/1,357 patients (29.7%; 355 moderate and 48 severe). Patients with stenosis, compared with those without, were older (71.7 ± 11 vs. 66.3 ± 12 years; p < 0.01). Females were more likely to have stenosis (odd ratio, = 1.7; 95% confidence interval, 1.4-2.2); however, patients were predominantly male in both groups. There were no significant differences in the rates of mortality and postoperative complications, including stroke and transient ischemic attack (TIA). Postoperative TIA occurred in 3/1,357(0.2%); only one had moderate stenosis. Inhospital stroke occurred in 21/1,357 (1.5%) patients; stroke rates were 2.3% (8/355) with moderate stenosis and 2.1% (1/48) severe stenosis. There were 59/1,357 (4.3%) deaths; patients with stenosis had a mortality rate of 4.2% (17/403); however, no postoperative stroke lead to death. Multivariable logistic regression analysis with adjustment for age, gender, race, comorbidities, and postoperative complications did not show an impact of carotid stenosis on postoperative mortality and development of stroke after cardiac surgery. Conclusion This study suggests that patients with asymptomatic carotid stenosis undergoing cardiac surgery are not at increased risk of postoperative complications and mortality; thus, prophylactic carotid revascularization may not be indicated.

    Subglottic stenosis is among the most common causes of airway obstruction in children, 90% of which resulting from endotracheal intubation. The diagnosis is based on the patient's clinical, radiologic evaluation, flexible laryngoscopy and rigid airway endoscopy under general anesthesia. It must be suspected in children with respiratory distress after extubation. The therapeutic approach depends on the severity of the subglottic stenosis and the patient's symptoms. We describe our experience with the subglottic stenosis etiologies, diagnosis, treatment and outcome of patients with this condition.
