The intention of this research was to define the predictive factors for acute esophagitis (AE) in lung cancer patients treated with concurrent chemotherapy and three-dimensional conformal radiotherapy. The data for 72 lung cancer patients treated with concurrent chemoradiotherapy between 2008 and 2010 were prospectively evaluated. Mean lung dose, mean dose of esophagus, volume of esophagus irradiated and percentage of esophagus volume treated were analysed according to esophagitis grades. The mean esophageal dose was associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P < 0.001). However, the mean lung dose and the volume of esophagus irradiated were not associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P = 0.50 and P = 0.41, respectively). The mean radiation dose received by the esophagus was found to be highly correlated with the duration of Grade 2 esophagitis (Spearman test, r = 0.82, P < 0.001). The mean dose of esophagus ≥28 Gy showed statistical significance with respect to AE Grade 2 or worse (receiver operating characteristic curve analysis, 95% CI, 0.929–1.014). In conclusion, the mean esophageal dose was significantly associated with a risk of esophageal toxicity in patients with lung cancer treated with concurrent radiotherapy and chemotherapy.

A 63-year-old woman with abdominal pain and melena developed a palpable, purpuric rash and acute kidney injury. Skin and kidney biopsy confirmed Henoch-Schönlein purpura. Upper endoscopy revealed diffuse, circumferential, black-appearing mucosa of the esophagus consistent with acute esophageal necrosis (AEN), also known as black esophagus. AEN is a very rare cause of gastrointestinal hemorrhage with a high mortality risk. To our knowledge, there have been no prior reports of AEN associated with Henoch-Schonlein purpura or other vasculitis. PMID:26504868

Black esophagus: Acute esophageal necrosis syndrome

PubMed Central

Gurvits, Grigoriy E

2010-01-01

Acute esophageal necrosis (AEN), commonly referred to as “black esophagus”, is a rare clinical entity arising from a combination of ischemic insult seen in hemodynamic compromise and low-flow states, corrosive injury from gastric contents in the setting of esophago-gastroparesis and gastric outlet obstruction, and decreased function of mucosal barrier systems and reparative mechanisms present in malnourished and debilitated physical states. AEN may arise in the setting of multiorgan dysfunction, hypoperfusion, vasculopathy, sepsis, diabetic ketoacidosis, alcohol intoxication, gastric volvulus, traumatic transection of the thoracic aorta, thromboembolic phenomena, and malignancy. Clinical presentation is remarkable for upper gastrointestinal bleeding. Notable symptoms may include epigastric/abdominal pain, vomiting, dysphagia, fever, nausea, and syncope. Associated laboratory findings may reflect anemia and leukocytosis. The hallmark of this syndrome is the development of diffuse circumferential black mucosal discoloration in the distal esophagus that may extend proximally to involve variable length of the organ. Classic “black esophagus” abruptly stops at the gastroesophageal junction. Biopsy is recommended but not required for the diagnosis. Histologically, necrotic debris, absence of viable squamous epithelium, and necrosis of esophageal mucosa, with possible involvement of submucosa and muscularis propria, are present. Classification of the disease spectrum is best described by a staging system. Treatment is directed at correcting coexisting clinical conditions, restoring hemodynamic stability, nil-per-os restriction, supportive red blood cell transfusion, and intravenous acid suppression with proton pump inhibitors. Complications include perforation with mediastinal infection/abscess, esophageal stricture and stenosis, superinfection, and death. A high mortality of 32% seen in the setting of AEN syndrome is usually related to the underlying medical co

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). 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. 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 > or =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). Concurrent chemotherapy and the maximal esophageal point dose > or =60 Gy are significantly associated with the risk of grade 3-5 esophageal injury in patients with NSCLC treated with 3D-CRT.

OBJECTIVES: To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD: Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obtained before surgery and 12 hours postoperatively to examine the total antioxidant status, total oxidant status, paraoxonase, stimulated paraoxonase, arylesterase, catalase, myeloperoxidase, ceruloplasmin, oxidative stress markers (advanced oxidized protein products and total thiol level) and ischemia-modified albumin. Surgical specimens were also evaluated. RESULTS: The diagnoses were acute appendicitis (n = 37), perforated appendicitis (n = 8), phlegmonous appendicitis (n = 12), perforated+phlegmonous appendicitis (n = 4), or no appendicitis (n = 4). The Alvarado score of the acute appendicitis group was significantly lower than that of the perforated+phlegmonous appendicitis group (p = 0.004). The serum total antioxidant status, total thiol level, advanced oxidized protein products, total oxidant status, catalase, arylesterase, and ischemia-modified albumin levels were significantly different between the acute appendicitis and control groups. There was no correlation between the pathological extent of acute appendicitis and the tissue levels of the markers; additionally, there was no correlation between the tissue and serum levels of any of the parameters. CONCLUSIONS: The imbalance of oxidant/antioxidant systems plays a role in the pathogenesis acute appendicitis. The Alvarado score can successfully predict the presence and extent of acute appendicitis. PMID:25518019

From Reflux Esophagitis to Esophageal Adenocarcinoma

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 secretion by squamous cells. We have shown that NO reduces expression of genes that promote a squamous cell phenotype, while Hedgehog signaling induces genes that mediate the development of the columnar cell phenotypes of Barrett's metaplasia. Agents targeting esophageal NO production or Hedgehog 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-κB 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-κB activation induced by toxic bile acids. Altering bile acid composition might be another approach to cancer prevention. PMID:27331918

In recent years, Nocardia farcinica has been reported to be an increasingly frequent cause of localized and disseminated infections in the immunocompromised patient. However, recent literature is limited. We report a case of left thigh phlegmon caused by N. farcinica that occurred in a patient with leprosy undergoing treatment with prednisone for leprosy reaction. We describe the case of left thigh phlegmon caused by Nocardia farcinica in a 54-year-old Italian man affected by multi-bacillary leprosy. The patient had worked in South America for 11 years. Seven months after his return to Italy, he was diagnosed with leprosy and started multi-drug antibiotic therapy plus thalidomide and steroids. Then, during therapy with rifampicin monthly, minocycline 100 mg daily, moxifloxacin 400 mg daily, and prednisone (the latter to treat type 2 leprosy reaction), the patient complained of high fever associated with erythema, swelling, and pain in the left thigh. Therefore, he was admitted to our hospital with the clinical suspicion of cellulitis. Ultrasound examination and Magnetic Resonance Imaging showed left thigh phlegmon. He was treated with drainage and antibiotic therapy (meropenem and vancomycin replaced by daptomycin). The responsible organism, Nocardia farcinica, was identified by 16S rRNA sequencing in the purulent fluid taken out by aspiration. The patient continued treatment with intravenous trimethoprim/sulfamethoxazole and imipenem followed by oral trimethoprim/sulfamethoxazole and moxifloxacin. A whole-body computed tomography did not reveal dissemination to other organs like the lung or brain.The patient was discharged after complete remission. Oral therapy with trimethoprim/sulfamethoxazole, moxifloxacin, rifampicin monthly, clofazimine and thalidomide was prescribed to be taken at home. One month after discharge from the hospital the patient is in good clinical condition with complete resolution of the phlegmon. N. farcinica is a rare infectious agent that

Acute kidney injury (AKI) has been increasingly recognized as a common and serious postoperative complication. Although many studies have been conducted to investigate postoperative AKI after thoracic surgery, little is known about AKI after esophageal surgery. Thus, we conducted this study to determine the incidence and identify risk factors of postoperative AKI after esophageal cancer surgery. A retrospective nested case-control study of patients undergoing elective esophageal cancer surgery between July 2013 and July 2016 in a single tertiary specialized cancer hospital was performed. The primary outcome was development of AKI. Conditional logistic regression analysis was performed to identify independent risk factors for AKI. Of 2094 patients, 51 (2.4%) developed postoperative AKI after esophageal cancer surgery. In multivariate conditional logistic regression analysis, four risk factors for AKI after esophageal surgery for cancer were identified: preoperative serum creatinine level (OR 1.040; 95% CI 1.012-1.069), duration of surgery (OR 1.009; 95% CI 1.005-1.014), smoking history (OR 3.029; 95% CI 1.092-8.399) and hypertension (OR 6.422; 95% CI 2.736-15.070). Postoperative AKI occurred in 2.4% of patients after esophageal surgery for cancer. Preoperative serum creatinine level, duration of surgery, smoking history and hypertension were independent risk factors for postoperative AKI. Copyright © 2017 IJS Publishing Group Ltd.

Acute esophageal necrosis (AEN), also called “black esophagus,” is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. The patients are usually older and are critically ill with shared comorbidities, which include atherosclerotic cardiovascular disease, diabetes mellitus, hypertension, chronic renal insufficiency, and malnutrition. Alcoholism and substance abuse could be seen in younger patients. Patients usually have systemic hypotension along with upper abdominal pain in the background of clinical presentation of hematemesis and melena. The endoscopic findings confirm the diagnosis and biopsy is not always necessary unless clinically indicated in atypical presentations. Herein we present two cases with distinct clinical presentation and discuss the endoscopic findings along with a review of the published literature on the management of AEN. PMID:27642529

Acute toxicity of definitive chemoradiation in patients with inoperable or irresectable esophageal carcinoma

PubMed Central

2014-01-01

Background Definitive chemoradiation (dCRT) is considered curative intent treatment for patients with inoperable or irresectable esophageal cancer. Acute toxicity data focussing on dCRT are lacking. Methods A retrospective analysis of patients treated with dCRT consisting of 6 cycles of paclitaxel 50 mg/m2 and carboplatin AUC2 concomitant with radiotherapy (50.4 Gy\\1.8Gy) from 2006 through 2011 at a single tertiary center was performed. Toxicity, hospital admissions and survival were analysed. Results 127 patients were treated with definitive chemoradiation. 33 patients were medically inoperable, 94 patients were irresectable, Despite of a significantly smaller tumor length in inoperable patients grade ≥3 toxicity was significantly recorded more often in the inoperable patients (44%) than in irresectable patients (20%) (p < 0.05) Hospital admission occurred more often in the inoperable patients (39%) than in the irresectable patients (22%) (p < 0.05) Median number of cycles of chemotherapy was five for inoperable patients (p = 0.01), while six cycles could be administered to patients with irresectable disease. Recurrence and survival were not significantly different. The odds ratio for developing toxicity ≥ grade 3 was 2.6 (95% CI 1.0-6.4 p < 0.05) for being an inoperable patient and 1.2 (95% CI 1.0-1.4 p = 0.02) per 10 extra micromol/l creatinine. Conclusions Our data show that acute toxicity of definitive chemoradiation is worse in patients with medically inoperable esophageal carcinoma compared to patients with irresectable esophageal cancer and mainly occurs in the 5th cycle of treatment. Improvement of supportive care should be undertaken in this more fragile group. PMID:24485047

The article considers the measured values of the level of MMP-1, MMP-8 and MMP-9, and of their tissue inhibitor Type I (TIMP-1) in the blood serum and mixed saliva samples of 78 patients (31 women - 36.2 %, 47 men - 63.8 %) suffering from odontogenic phlegmons in the oral and maxillofacial region. The study indicators were assessed through the enzyme-linked immunosorbent assay using diagnostic sets RandD Diagnostics Inc. (USA). An uncontrolled hyperactivation of metal proteinases as one of the components of the systemic inflammatory response in case of phlegmon-related complications in the oral and maxillofacial region, as well as development of the sepsis syndrome were studied and it was determined that it results in distortion of the processes of reparative hystogeny and compel us to employ new approaches to the treatment of this type of patients (Tab. 2, Fig. 1, Ref. 13).

Polyunsaturated fatty acids (PUFAs) play various roles in inflammation. However, the effect of PUFAs in the development of reflux esophagitis (RE) is unclear. This study is to investigate the potential effect of n-3/n-6 PUFAs on acute RE in rats along with the underlying protective mechanisms. Forty Sprague Dawley rats were randomly divided into four groups (n = 10 in each group). RE model was established by pyloric clip and section ligation. Fish oil- and soybean oil-based fatty emulsion (n-3 and n-6 groups), or normal saline (control and sham operation groups) was injected intraperitoneally 2 h prior to surgery and 24 h postoperatively (2 mL/kg, respectively). The expressions of interleukin (IL)-1β, IL-8, IL-6 and myeloid differentiation primary response gene 88 (MyD88) in esophageal tissues were evaluated by Western blot and immunohistochemistry after 72 h. The malondialdehyde (MDA) and superoxide dismutase (SOD) expression in the esophageal tissues were determined to assess the oxidative stress. The mildest macroscopic/microscopic esophagitis was found in the n-3 group (P < 0.05). The expression of IL-1β, IL-8, IL-6 and MyD88 were increased in all RE groups, while the lowest and highest expression were found in n-3 and n-6 group, respectively (P < 0.05). The MDA levels were increased in all groups (P < 0.05), in an ascending trend from n-3, n-6 groups to control group. The lowest and highest SOD levels were found in the control and n-3 group, respectively (P < 0.05). n-3 PUFAs may reduce acute RE in rats, which may be due to inhibition of the MyD88-NF-kB pathway and limit oxidative damage.

To evaluate the clinical and three-dimensional dosimetric parameters associated with esophageal injury after radiotherapy (RT) for non-small-cell lung cancer. The records of 254 patients treated for non-small-cell lung cancer between 1992 and 2001 were reviewed. A variety of metrics describing the esophageal dose were extracted. The Radiation Therapy Oncology Group toxicity criteria for grading of esophageal injury were used. The median follow-up time for all patients was 43 months (range, 0.5-120 months). Logistic regression analysis, contingency table analyses, and Fisher's exact tests were used for statistical analysis. Acute toxicity occurred in 199 (78%) of 254 patients. For acute toxicity of Grade 2 or worse, twice-daily RT, age, nodal stage of N2 or worse, and most dosimetric parameters were predictive. Late toxicity occurred in 17 (7%) of 238 patients. The median and maximal time to the onset of late toxicity was 5 and 40 months after RT, respectively. Late toxicity occurred in 2%, 3%, 17%, 26%, and 100% of patients with acute Grade 0, 1, 2, 3, and 4 toxicity, respectively. For late toxicity, the severity of acute toxicity was most predictive. A variety of dosimetric parameters are predictive of acute and late esophageal injury. A strong correlation between the dosimetric parameters prevented a comparison between the predictive abilities of these metrics. The presence of acute injury was the most predictive factor for the development of late injury. Additional studies to define better the predictors of RT-induced esophageal injury are needed.

The pathology of acute appendicitis.

Although acute appendicitis is frequent, it is subject to common misconceptions. Furthermore, there is little good evidence to support some of our beliefs. This report reviews the role of the anatomic pathologist in diagnosis when acute appendicitis is suspected clinically and discusses what is known of its pathology. The conclusions that can be legitimately drawn from the literature are emphasized. A classification is proposed that incorporates intraluminal inflammation, acute mucosal inflammation, acute mucosal and submucosal inflammation, suppurative (phlegmonous) appendicitis, gangrenous appendicitis, and periappendicitis, and the significance of each of these diagnoses is discussed. The etiology and pathogenesis of acute appendicitis is reviewed. Contrary to popular belief, the best evidence indicates that obstruction is unlikely to be the primary cause, at least in the majority of cases. Ancillary techniques in the diagnosis of appendicitis, including laparoscopy and peritoneal aspiration cytology, are discussed.

In our previous work, a multivariable normal-tissue complication probability (NTCP) model for acute esophageal toxicity (AET) Grade  ⩾2 after highly conformal (chemo-)radiotherapy for non-small cell lung cancer (NSCLC) was developed using multivariable logistic regression analysis incorporating clinical parameters and mean esophageal dose (MED). Since the esophagus is a tubular organ, spatial information of the esophageal wall dose distribution may be important in predicting AET. We investigated whether the incorporation of esophageal wall dose-surface data with spatial information improves the predictive power of our established NTCP model. For 149 NSCLC patients treated with highly conformal radiation therapy esophageal wall dose-surface histograms (DSHs) and polar dose-surface maps (DSMs) were generated. DSMs were used to generate new DSHs and dose-length-histograms that incorporate spatial information of the dose-surface distribution. From these histograms dose parameters were derived and univariate logistic regression analysis showed that they correlated significantly with AET. Following our previous work, new multivariable NTCP models were developed using the most significant dose histogram parameters based on univariate analysis (19 in total). However, the 19 new models incorporating esophageal wall dose-surface data with spatial information did not show improved predictive performance (area under the curve, AUC range 0.79-0.84) over the established multivariable NTCP model based on conventional dose-volume data (AUC  =  0.84). For prediction of AET, based on the proposed multivariable statistical approach, spatial information of the esophageal wall dose distribution is of no added value and it is sufficient to only consider MED as a predictive dosimetric parameter.

145 patients (60 with phlegmons of submandibular and submental regions, 85--with fractures of mandible) were observed and treated with the use of moving pulse magnetic field (MPMF) produced by special apparatus (AMO-ATOS-E, , Saratov-city), 60 patients with the same pathology were treated by traditional physical methods and served as control. Use of MPMF led to quicker patient recovery: quicker reduction (if compared with traditional physical methods of treatment) of oedema and soft tissue inflammatory infiltration, quicker relief from inflammatory reaction (according to data of cytokinin profile), improvement of tissue blood supply in the region of fractures in patients with mandible fractures. As the result--we had shortening treatment terms of such patients and complication number reduction.

To ascertain the accuracy and reliability of tablet as an imaging console for detection of radiological signs of acute appendicitis [on focused appendiceal computed tomography (FACT)] using Picture Archiving and Communication System (PACS) workstation as reference standard. From January, 2014 to June, 2015, 225 patients underwent FACT at our institution. These scans were blindly re-interpreted by an independent consultant radiologist, first on PACS workstation and, two weeks later, on tablet. Scans were interpreted for the presence of radiological signs of acute appendicitis. Accuracy of tablet was calculated using PACS as reference standard. Kappa (κ) statistics were calculated as a measure of reliability. Of 225 patients, 99 had radiological evidence of acute appendicitis on PACS workstation. Tablet was 100% accurate in detecting radiological signs of acute appendicitis. Appendicoliths, free fluid, lymphadenopathy, phlegmon/abscess, and perforation were identified on PACS in 90, 43, 39, 10, and 12 scans, respectively. There was excellent agreement between tablet and PACS for detection of appendicolith (к = 0.924), phlegmon/abscess (к = 0.904), free fluid (к = 0.863), lymphadenopathy (к = 0.879), and perforation (к = 0.904). Tablet computer, as an imaging console, was highly reliable and was as accurate as PACS workstation for the radiological diagnosis of acute appendicitis.

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.

Esophageal neoplasia is an uncommon, but important, consideration for acute and chronic regurgitation and megaesophagus in dogs. The diagnosis can be challenging, and treatment options are often limited. This case series describes four dogs with regurgitation secondary to caudal esophageal masses. All dogs presented with regurgitation, and three of the four dogs had radiographically apparent megaesophagus. In all dogs, ancillary diagnostics revealed the presence of a caudal esophageal mass resulting in esophageal obstruction, and all mass lesions were histopathologically confirmed to be neoplastic. Treatment responses were variable, with one dog still alive 37 mo postdiagnosis at the time of manuscript preparation.

Radiation pneumonitis (RP) is a common side reaction in radiotherapy for esophageal cancer. There are few reports about RP in esophageal cancer patients receiving postoperative intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). This study aims to analyze clinical or dosimetric factors associated with RP, and provides data for radiotherapy planning. We reviewed 68 postoperative esophageal cancer patients who were treated with radiotherapy at the West China Hospital from October 2010 to November 2012 to identify any correlation between the clinical or dosimetric parameters and acute radiation pneumonitis (ARP) or severe acute radiation pneumonitis (SARP) by t-test, chi-square test, and logistic regression analysis. Of the 68 patients, 33 patients (48.5%) developed ARP, 13 of which (19.1%) developed SARP. Of these 33 patients, 8 (11.8%), 12 (17.6%), 11 (16.2%), and 2 (2.9%) patients were grade 1, 2, 3, and 4 ARP, respectively. Univariate analysis showed that lung infection during radiotherapy, use of VMAT, mean lung dose (MLD), and dosimetric parameters (e.g. V20, V30) are significantly correlated with RP. Multivariate analysis found that lung infection during radiotherapy, MLD ≥ 12 Gy, and V30 ≥ 13% are significantly correlated with an increased risk of RP. Lung infection during radiotherapy and low radiation dose volume distribution were predictive factors associated with RP and should be accounted for during radiation planning.

Eosinophilic esophagitis in patients with esophageal atresia and chronic dysphagia.

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.

To investigate the predictive value of low dose volume of the lung on acute radiation pneumonitis (RP) in patients with esophageal cancer treated with three-dimensional conformal radiotherapy (3D-CRT) only, and to analyze the relation of comprehensive parameters of the dose-volume V5, V20 and mean lung dose (MLD) with acute RP. Two hundred and twenty-two patients with esophageal cancer treated by 3D-CRT have been followed up. The V5-V30 and MLD were calculated from the dose-volume histogram system. The clinical factors and treatment parameters were collected and analyzed. The acute RP was evaluated according to the RTOG toxicity criteria. The acute RP of grade 1, 2, 3 and 4 were observed in 68 (30.6%), 40 (18.0%), 8 (3.6%) and 1 (0.5%) cases, respectively. The univariate analysis of measurement data:The primary tumor length, radiation fields, MLD and lung V5-V30 had a significant relationship with the acute RP. The magnitude of the number of radiation fields, the volume of GTV, MLD and Lung V5-V30 had a significant difference in whether the ≥ grade 1 and ≥ grade 2 acute RP developed or not. Binary logistic regression analysis showed that MLD, Lung V5, V20 and V25 were independent risk factors of ≥ grade 1 acute RP, and the radiation fields, MLD and Lung V5 were independent risk factors of ≥ grade 2 acute RP. The ≥ grade 1 and ≥ grade 2 acute RP were significantly decreased when MLD less than 14 Gy, V5 and V20 were less than 60% and 28%,respectively. When the V20 ≤ 28%, the acute RP was significantly decreased in V5 ≤ 60% group. When the MLD was ≤ 14 Gy, the ≥ 1 grade acute RP was significantly decreased in the V5 ≤ 60% group. When the MLD was >14 Gy, the ≥ grade 2 acute RP was significantly decreased in the V5 ≤ 60% group. The low dose volume of the lung is effective in predicting radiation pneumonitis in patients with esophageal cancer treated with 3D-CRT only. The comprehensive parameters combined with V5, V20 and MLD may increase the

Esophageal motility in eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) is characterized by eosinophilic infiltration of the esophagus and is a potential cause of dysphagia and food impaction, most commonly affecting young men. Esophageal manometry findings vary from normal motility to aperistalsis, simultaneous contractions, diffuse esophageal spasm, nutcracker esophagus or hypotonic lower esophageal sphincter (LES). It remains unclear whether esophageal dysmotility plays a significant role in the clinical symptoms of EoE. Our aim is to review the pathogenesis, diagnosis, and effect of treatment on esophageal dysmotility in EoE. A literature search utilizing the PubMed database was performed using keywords: eosinophilic esophagitis, esophageal dysmotility, motility, manometry, impedance planimetry, barium esophagogram, endoscopic ultrasound, and dysphagia. Fifteen studies, totaling 387 patients with eosinophilic esophagitis were identified as keeping in accordance with the aim of this study and included in this review. The occurrence of abnormal esophageal manometry was reported to be between 4 and 87% among patients with EoE. Esophageal motility studies have shown reduced distensibility, abnormal peristalsis, and hypotonicity of the LES in patients with EoE, which may also mimic other esophageal motility disorders such as achalasia or nutcracker esophagus. Studies have shown conflicting results regarding the presence of esophageal dysmotility and symptoms with some reports suggesting a higher rate of food impaction, while others report no correlation between motor function and dysphagia. Motility dysfunction of the esophagus in EoE has not been well reported in the literature and studies have reported conflicting evidence regarding the clinical significance of dysmotility seen in EoE. The correlation between esophageal dysmotility and symptoms of EoE remains unclear. Larger studies are needed to investigate the incidence of esophageal dysmotility, clinical implications, and effect of treatment on

Purpose: To construct a maximally predictive model of the risk of severe acute esophagitis (AE) for patients who receive definitive radiation therapy (RT) for non-small-cell lung cancer. Methods and Materials: The dataset includes Washington University and RTOG 93-11 clinical trial data (events/patients: 120/374, WUSTL = 101/237, RTOG9311 = 19/137). Statistical model building was performed based on dosimetric and clinical parameters (patient age, sex, weight loss, pretreatment chemotherapy, concurrent chemotherapy, fraction size). A wide range of dose-volume parameters were extracted from dearchived treatment plans, including Dx, Vx, MOHx (mean of hottest x% volume), MOCx (mean of coldest x% volume), and gEUDmore » (generalized equivalent uniform dose) values. Results: The most significant single parameters for predicting acute esophagitis (RTOG Grade 2 or greater) were MOH85, mean esophagus dose (MED), and V30. A superior-inferior weighted dose-center position was derived but not found to be significant. Fraction size was found to be significant on univariate logistic analysis (Spearman R = 0.421, p < 0.00001) but not multivariate logistic modeling. Cross-validation model building was used to determine that an optimal model size needed only two parameters (MOH85 and concurrent chemotherapy, robustly selected on bootstrap model-rebuilding). Mean esophagus dose (MED) is preferred instead of MOH85, as it gives nearly the same statistical performance and is easier to compute. AE risk is given as a logistic function of (0.0688 Asterisk-Operator MED+1.50 Asterisk-Operator ConChemo-3.13), where MED is in Gy and ConChemo is either 1 (yes) if concurrent chemotherapy was given, or 0 (no). This model correlates to the observed risk of AE with a Spearman coefficient of 0.629 (p < 0.000001). Conclusions: Multivariate statistical model building with cross-validation suggests that a two-variable logistic model based on mean dose and the use of concurrent chemotherapy robustly

Hydropneumothorax Due to Esophageal Rupture.

A brief review of the historical aspects of esophageal rupture is presented along with a case and current recommendations for diagnostic evaluation and treatment. A 97-year-old woman complained of acute dyspnea without prior vomiting. Chest x-ray study showed a large right pneumothorax with associated effusion. A thoracostomy tube was placed with return of > 1 L turbid fluid with polymicrobial culture and elevated pleural fluid amylase level. Chest computed tomography (CT) scan demonstrated overt leakage of oral contrast into the right pleural space. She was treated with ongoing pleural evacuation, antibiotics, antifungals, and total parenteral nutrition. The patient and family declined surgical resection as well as endoscopic stent placement. In 1724, Boerhaave described spontaneous rupture of the esophagus postmortem; Boerhaave syndrome remains the name for complete disruption of the esophageal wall in the absence of pre-existing pathology typically occurring after vomiting. It most commonly occurs in the distal left posterolateral thoracic esophagus. Contrast esophagram is considered the "gold standard" for diagnosing esophageal rupture although CT esophagography also shows good diagnostic performance. Treatment includes nil per os status, broad-spectrum antibiotics, and drainage of the pleural space. Surgical repair of the esophageal perforation should be done early if the patient is deemed a good candidate, and esophageal stenting is also an option. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Esophageal perforation should be suspected in patients with new pleural effusion, often with overt pneumothorax, that is polymicrobial with elevated amylase.

A new hypermetabolic lesion on 18 FDG-PET/CT after neo-adjuvant chemoradiotherapy for distal esophageal cancer can be a hepatic metastasis and should be examined carefully before esophagectomy. We present a case of acute and nodular radiation-induced injury of the left liver after neo-adjuvant chemoradiotherapy for distal esophageal cancer, which resembles a hepatic metastasis on 18 FDG-PET/CT. Acute and nodular radiation hepatitis (RH) can be a potential cause of false-positive findings of malignancy and therefore exclude patients who could benefit from esophagectomy. 18 FDG-PET/CT images should therefore carefully be interpreted and compared with the radiation beams, dose distribution and eventually clarified by DW-MR imaging.

To evaluate the incidence and clinical/dosimetric predictors of acute and late Radiation Therapy Oncology Group Grade 3-5 esophageal toxicity in patients with non-small-cell lung cancer (NSCLC) treated with definitive three-dimensional conformal radiotherapy (3D-CRT). We retrospectively reviewed the charts of 207 consecutive patients with NSCLC who were treated with high-dose, definitive 3D-CRT between March 1991 and December 1998. This population consisted of 107 men and 100 women. The median age was 67 years (range 31-90). The following patient and treatment parameters were studied: age, gender, race, performance status, sequential chemotherapy, concurrent chemotherapy, presence of subcarinal 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. All doses are reported without heterogeneity corrections. The median prescription dose to the isocenter in this population was 70 Gy (range 60-74) delivered in 2-Gy daily fractions. All patients were treated once daily. Acute and late esophageal toxicities were graded by Radiation Therapy Oncology Group criteria. Patient and clinical/dosimetric factors were coded and correlated with acute and late Grade 3-5 esophageal toxicity using univariate and multivariate regression analyses. Of 207 patients, 16 (8%) developed acute (10 patients) or late (13 patients) Grade 3-5 esophageal toxicity. Seven patients had both acute and late Grade 3-5 esophageal toxicity. One patient died (Grade 5 esophageal toxicity) of late esophageal perforation. Concurrent chemotherapy, maximal point dose to the esophagus >58 Gy, and a mean dose to the entire esophagus >34 Gy were significantly associated with a risk of Grade 3-5 esophageal toxicity on univariate analysis. Concurrent chemotherapy and maximal point dose to the esophagus >58 Gy retained significance on multivariate analysis. Of 207 patients, 53 (26%) received concurrent

To evaluate esophageal body motor contractions occurring during esophageal reflux in pediatric patients with gastro-esophageal reflux disease (GERD). Patients referred for the evaluation of GERD who were evaluated with combined 24-hour pH probe and esophageal manometry test (MP24) were included. Patients were separated into the following groups: Group C -- normal pH probe and normal EGD; Group 1 -- abnormal pH probe and normal EGD; and Group 2 -- abnormal pH probe and EGD with histologic esophagitis. Esophageal motor function during reflux episodes was analyzed. Twenty-five patients were included. All had a normal stationary esophageal manometry. Patients in Groups 1 and 2 had significantly more gastroesophageal reflux by pH probe than Group C (P < 0.01). During the MP24, patients in Group 1 and 2 had significantly fewer contractions per minute pre-, during, and post-GER (P < 0.05). There were significant differences in the number of isolated and prolonged contractions (>7 sec) during prolonged GERD episodes >5 minutes (P < 0.05). Children with GERD have a decreased number and abnormal esophageal body contractions with esophageal reflux. This suggests that children with GERD with and without esophagitis have impaired esophageal body acid clearance.

Radiation-induced lung toxicity occurs frequently in patients with esophageal carcinoma. This study aims to evaluate the clinical and three-dimensional dosimetric parameters associated with lung toxicity after radiotherapy for esophageal carcinoma. The records of 56 patients treated for esophageal carcinoma were reviewed. The Radiation Therapy Oncology Group criteria for grading of lung toxicity were followed. Spearman's correlation test, the chi-square test and logistic regression analyses were used for statistical analysis. Ten of the 56 patients developed acute toxicity. The toxicity grades were grade 2 in 7 patients and grade 3 in 3 patients; none of the patients developed grade 4 or worse toxicity. One case of toxicity occurred during radiotherapy and 9 occurred 2 weeks to 3 months after radiotherapy. The median time was 2.0 months after radiotherapy. Fourteen patients developed late irradiated lung injury, 3 after 3.5 months, 7 after 9 months, and 4 after 14 months. Radiographic imaging demonstrated patchy consolidation (n = 5), atelectasis with parenchymal distortion (n = 6), and solid consolidation (n = 3). For acute toxicity, the irradiated esophageal volume, number of fields, and most dosimetric parameters were predictive. For late toxicity, chemotherapy combined with radiotherapy and other dosimetric parameters were predictive. No obvious association between the occurrence of acute and late injury was observed. The percent of lung tissue receiving at least 25 Gy (V25), the number of fields, and the irradiated length of the esophagus can be used as predictors of the risk of acute toxicity. Lungs V30, as well as chemotherapy combined with radiotherapy, are predictive of late lung injury.

A 59 years old woman was admitted in our unit accusing longtime dysphagia and regurgitation. On admission, the patient was wearing a 3 month old definitive feeding gastrostomy tube. The contrast swallow, endoscopy and esophageal manometry established the diagnostic--achalasia. We removed the gastrostomy tube and we performed an open Heller myotomy. The postoperative period was uneventful and the patient was discharged one week later with affirmatively unimpaired deglutition. One month later, the patient was admitted via emergency with a giant fibrous tumor arising from her mouth after an episode of strong coughing and vomiting. The repeated endoscopy showed a giant esophageal polyp that was missed by the previous investigations, originating from pharingoesophageal junction. The esophageal polyp was resected by cervical approach with good postoperative outcome. The polyp's particular extreme dimensions (27 cm) prevented the acute asphyxia by blockage at the laryngeal level, possibly provoked by smaller tumors. As postoperative one month barium swallow showed a normal esophageal aspect, a final question remains--was achalasia real or an erroneous diagnosis was established the second time too?

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. 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 10cm 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. 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. In this case, the patient's symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Esophageal thermal injury caused by food has been reported to occur mostly after drinking hot liquid food, and is known to produce alternating white and red linear mucosal bands. In addition, thermal injury caused by ingestion of hot solid foods is documented to be a cause of esophageal ulcers or pseudomembranes. From January 2006 to August 2012, five patients with suspected esophageal thermal injury underwent esophagogastroduodenoscopy with biopsy. A "candy-cane" appearance was observed in one case, pseudomembrane was observed in two cases, an esophageal ulcer was observed in one case, and a friable and edematous mucosa was noted in one case. We believe that the endoscopic findings of esophageal thermal injury depend on the following factors: causative materials, amount of food consumed, exposure period, and time to endoscopy after the incident. Therefore, physicians who encounter patients with suspected esophageal thermal injury should carefully take the patient's history considering these factors.

A Prospective Study of Proton Beam Reirradiation for Esophageal Cancer

Fernandes, Annemarie, E-mail: Annemarie.fernandes@gmail.com; Berman, Abigail T.; Mick, Rosemarie

Purpose: Reirradiation to the esophagus carries a significant risk of complications. Proton therapy may offer an advantage in the reirradiation setting due to the lack of exit dose and potential sparing of previously radiated normal tissues. Methods and Materials: Between June 2010 and February 2014, 14 patients with a history of thoracic radiation and newly diagnosed or locally recurrent esophageal cancer began proton beam reirradiation on a prospective trial. Primary endpoints were feasibility and acute toxicity. Toxicity was graded according Common Toxicity Criteria version 4.0. Results: The median follow-up was 10 months (2-25 months) from the start of reirradiation. Eleven patients receivedmore » concurrent chemotherapy. The median interval between radiation courses was 32 months (10-307 months). The median reirradiation prescription dose was 54.0 Gy (relative biological effectiveness [RBE]) (50.4-61.2 Gy[RBE]), and the median cumulative prescription dose was 109.8 Gy (76-129.4 Gy). Of the 10 patients who presented with symptomatic disease, 4 patients had complete resolution of symptoms, and 4 had diminished or stable symptoms. Two patients had progressive symptoms. The median time to symptom recurrence was 10 months. Maximum acute nonhematologic toxicity attributable to radiation was grade 2 (64%, N=9), 3 (29%, N=4), 4 (0%), and 5 (7%, N=1). The acute grade 5 toxicity was an esophagopleural fistula more likely related to tumor progression than radiation. Grade 3 nonhematologic acute toxicities included dysphagia, dehydration, and pneumonia. There was 1 late grade 5 esophageal ulcer more likely related to tumor progression than radiation. There were 4 late grade 3 toxicities: heart failure, esophageal stenosis requiring dilation, esophageal ulceration from tumor, and percutaneous endoscopic gastrostomy tube dependence. The median time to local failure was 10 months, and the median overall survival was 14 months. Conclusions: Our data demonstrate

Reirradiation to the esophagus carries a significant risk of complications. Proton therapy may offer an advantage in the reirradiation setting due to the lack of exit dose and potential sparing of previously radiated normal tissues. Between June 2010 and February 2014, 14 patients with a history of thoracic radiation and newly diagnosed or locally recurrent esophageal cancer began proton beam reirradiation on a prospective trial. Primary endpoints were feasibility and acute toxicity. Toxicity was graded according Common Toxicity Criteria version 4.0. The median follow-up was 10 months (2-25 months) from the start of reirradiation. Eleven patients received concurrent chemotherapy. The median interval between radiation courses was 32 months (10-307 months). The median reirradiation prescription dose was 54.0 Gy (relative biological effectiveness [RBE]) (50.4-61.2 Gy[RBE]), and the median cumulative prescription dose was 109.8 Gy (76-129.4 Gy). Of the 10 patients who presented with symptomatic disease, 4 patients had complete resolution of symptoms, and 4 had diminished or stable symptoms. Two patients had progressive symptoms. The median time to symptom recurrence was 10 months. Maximum acute nonhematologic toxicity attributable to radiation was grade 2 (64%, N=9), 3 (29%, N=4), 4 (0%), and 5 (7%, N=1). The acute grade 5 toxicity was an esophagopleural fistula more likely related to tumor progression than radiation. Grade 3 nonhematologic acute toxicities included dysphagia, dehydration, and pneumonia. There was 1 late grade 5 esophageal ulcer more likely related to tumor progression than radiation. There were 4 late grade 3 toxicities: heart failure, esophageal stenosis requiring dilation, esophageal ulceration from tumor, and percutaneous endoscopic gastrostomy tube dependence. The median time to local failure was 10 months, and the median overall survival was 14 months. Our data demonstrate that proton reirradiation is feasible, with an encouraging symptom control

Eosinophilic esophagitis is a chronic immunoallergic inflammatory disease of the esophagus that represents a major cause of digestive morbidity among the pediatric and young adult populations. Despite the fact that key symptoms in adults include dysphagia and food impaction, many patients lack structural changes in the esophagus to account for their complaints, which suggests the presence of underlying motor disorders and esophageal distensibility impairment. In the last few years the esophageal motility of these patients has been studied using various approaches, most particularly high-resolution manometry, ambulatory manometry, and impedance planimetry. This review focuses on the most relevant findings and scientific evidence regarding esophageal motor disorders in eosinophilic esophagitis.

Leak after esophageal anastomosis or perforation repair prolongs hospitalization, prevents oral hydration and nutrition, and can produce localized infection or sepsis. This investigation reviews our experience treating postoperative esophageal leaks with the Polyflex esophageal stent (Boston Scientific, Natick, Mass). Over a 30-month period, patients with a postoperative esophageal leak were treated with the Polyflex stent for leak occlusion. Leak occlusion was confirmed by means of esophagraphy. Patients were followed until their stent was removed and their esophageal leak had resolved. Twenty-one patients had 27 stents placed for leak occlusion after esophagectomy (n = 5), esophageal perforation (n = 5), surgical (n = 4) or endoscopic (n = 2) antireflux procedure, and esophageal diverticulectomy (n = 3) or myotomy (n = 2). The mean interval between surgical intervention and stent placement was 12 +/- 8 days (range, 3-31 days). Occlusion of the leak occurred in 20 patients. One patient experienced a dehiscence of the surgical esophageal perforation repair requiring esophageal diversion. Stent migration requiring repositioning (n = 3) or replacement (n = 4) occurred in 5 (24%) patients. Twenty (95%) stents were removed without residual leak (mean, 51 +/- 43 days; range, 15-175 days). One patient had a stricture after stent removal that required endoscopic dilatation. One patient in this series died. The Polyflex esophageal stent is an effective method for occluding a postoperative esophageal leak. It rapidly eliminates contamination of the mediastinum, pleura, and peritoneum; allows oral hydration and nutrition; and is easily removable. These stents also offer an appealing alternative to traditional esophageal diversion and subsequent reconstruction in patients with a persistent esophageal leak.

Rationale: Consideration of lung transplantation in patients with systemic sclerosis (SSc) remains guarded, often due to the concern for esophageal dysfunction and the associated potential for allograft injury and suboptimal post–lung transplantation outcomes. Objectives: The purpose of this study was to systematically report our single-center experience regarding lung transplantation in the setting of SSc, with a particular focus on esophageal dysfunction. Methods: We retrospectively reviewed all lung transplants at our center from January 1, 2000 through August 31, 2012 (n = 562), comparing the SSc group (n = 35) to the following lung transplant diagnostic subsets: all non-SSc (n = 527), non-SSc diffuse fibrotic lung disease (n = 264), and a non-SSc matched group (n = 109). We evaluated post–lung transplant outcomes, including survival, primary graft dysfunction, acute rejection, bronchiolitis obliterans syndrome, and microbiology of respiratory isolates. In addition, we defined severe esophageal dysfunction using esophageal manometry and esophageal morphometry criteria on the basis of chest computed tomography images. For patients with SSc referred for lung transplant but subsequently denied (n = 36), we queried the reason(s) for denial with respect to the concern for esophageal dysfunction. Measurements and Main Results: The 1-, 3-, and 5-year post–lung transplant survival for SSc was 94, 77, and 70%, respectively, and similar to the other groups. The remaining post–lung transplant outcomes evaluated were also similar between SSc and the other groups. Approximately 60% of the SSc group had severe esophageal dysfunction. Pre–lung transplant chest computed tomography imaging demonstrated significantly abnormal esophageal morphometry for SSc when compared with the matched group. Importantly, esophageal dysfunction was the sole reason for lung transplant denial in a single case. Conclusions: Relative to other lung transplant

Purpose: To evaluate acute cardiac effects of concurrent chemoradiotherapy (CCRT) for esophageal cancer. Methods and Materials: This prospective study was approved by the institutional review board, and written informed consent was obtained from all participants. The left ventricular function (LVF) of 31 patients with esophageal cancer who received cisplatin and 5-fluorouracil-based CCRT was evaluated using cardiac cine magnetic resonance imaging. The patients were classified into two groups according to mean LV dose. The parameters related to LVF were compared between before and during (40 Gy) or between before and after CCRT using a Wilcoxon matched-pairs single rank test, and parametermore » ratios (during/before CCRT, after/before CCRT) were also compared between the groups with a t test. Data were expressed as mean {+-} SE. Results: In the low LV-dose group (n = 10; mean LV dose <0.6 Gy), LV ejection fraction decreased significantly (before vs. during vs. after CCRT; 62.7% {+-} 2.98% vs. 59.8% {+-} 2.56% vs. 60.6% {+-} 3.89%; p < 0.05). In the high LV-dose group (n = 21; mean LV dose of 3.6-41.2 Gy), LV end-diastolic volume index (before vs. after CCRT; 69.1 {+-} 2.93 vs. 57.0 {+-} 3.23 mL/m{sup 2}), LV stroke volume index (38.6 {+-} 1.56 vs. 29.9 {+-} 1.60 mL/m{sup 2}), and LV ejection fraction (56.9% {+-} 1.79% vs. 52.8% {+-} 1.15%) decreased significantly (p < 0.05) after CCRT. Heart rate increased significantly (before vs. during vs. after CCRT; 66.8 {+-} 3.05 vs. 72.4 {+-} 4.04 vs. 85.4 {+-} 3.75 beats per minute, p < 0.01). Left ventricle wall motion decreased significantly (p < 0.05) in segments 8 (before vs. during vs. after CCRT; 6.64 {+-} 0.54 vs. 4.78 {+-} 0.43 vs. 4.79 {+-} 0.50 mm), 9 (6.88 {+-} 0.45 vs. 5.04 {+-} 0.38 vs. 5.27 {+-} 0.47 mm), and 10 (9.22 {+-} 0.48 vs. 8.08 {+-} 0.34 vs. 8.19 {+-} 0.56 mm). The parameter ratios of LV end-diastolic volume index, stroke volume index, wall motion in segment 9, and heart rate showed significant

The most effective treatment of achalasia is Heller myotomy. To explore a submucosal endoscopic myotomy technique tailored on esophageal physiology testing and to compare it with the open technique. Prospective acute and survival comparative study in pigs (n = 12; 35 kg). University animal research center. Eight acute-4 open and 4 endoscopic-myotomies followed by 4 survival endoscopic procedures. Preoperative and postoperative manometry; esophagogastric junction (EGJ) distensibility before and after selective division of muscular fibers at the EGJ and after the myotomy was prolonged to a standard length by using the EndoFLIP Functional Lumen Imaging Probe (Crospon, Galway, Ireland). All procedures were successful, with no intraoperative and postoperative complications. In the survival group, the animals recovered promptly from surgery. Postoperative manometry demonstrated a 50% drop in mean lower esophageal sphincter pressure (LESp) in the endoscopic group (mean preoperative LESp, 22.2 ± 3.3 mm Hg; mean postoperative LESp, 11.34 ± 2.7 mm Hg; P < .005) and a 69% loss in the open procedure group (mean preoperative LESp, 24.2 ± 3.2 mm Hg; mean postoperative LESp, 7.4 ± 4 mm Hg; P < .005). The EndoFLIP monitoring did not show any distensibility difference between the 2 techniques, with the main improvement occurring when the clasp circular fibers were taken. Healthy animal model; small sample. Endoscopic submucosal esophageal myotomy is feasible and safe. The lack of a significant difference in EGJ distensibility between the open and endoscopic procedure is very appealing. Were it to be perfected in a human population, this endoscopic approach could suggest a new strategy in the treatment of selected achalasia patients.

Abstract Esophageal xanthoma is a rare lesion which is an asymptomatic small yellowish polyp, and most of the reported cases were solitary lesion. Histologically, aggregations of foam cells are found under the papillary hypertrophic squamous epithelium and the foam cells express CD68. The etiology of esophageal xanthoma is unknown. The focal irritation of the esophageal mucosa and infiltrated inflammatory cells are presumed to contribute to its pathogenesis. Although the pathogenesis may be associated with inflammation, the type and nature of the macrophages remain unclear. Here we report a 46-year-old male with esophageal xanthoma, which was incidentally found by endoscopy. Histologically, acute inflammation was not noted, and immunohistochemistry revealed that the foam cells seen in this case of esophageal xanthoma expressed increased levels of M2 macrophage markers. These findings suggest that esophageal xanthoma is associated with late inflammatory and reparative processes long after the initial inflammation of esophageal squamous epithelium. PMID:29071304

Clinical Implications and Pathogenesis of Esophageal Remodeling in Eosinophilic Esophagitis

PubMed Central

2014-01-01

In eosinophilic esophagitis (EoE), remodeling changes are manifest histologically in both the epithelium as well as in the subepithelium where lamina propria (LP) fibrosis, expansion of the muscularis propria and increased vascularity occur. The major clinical symptoms and complications of EoE are largely consequences of esophageal remodeling. Important mediators of the process include IL-5, IL-13, TGFβ1, mast cells, fibroblasts and eosinophils. Methods to detect remodeling effects include upper endoscopy, histopathology, barium esophagram, endoscopic ultrasonography, esophageal manometry, and functional luminal imaging. These modalities provide evidence of organ dysfunction that include focal and diffuse esophageal strictures, expansion of the mucosa and subepithelium, esophageal motor abnormalities and reduced esophageal distensibility. Complications of food impaction and perforations of the esophageal wall have been associated with reduction in esophageal caliber and increased esophageal mural stiffness. The therapeutic benefits of topical corticosteroids and elimination diet therapy in resolving mucosal eosinophilic inflammation of the esophagus are evident. Available therapies, however, have demonstrated variable ability to reverse existing remodeling changes of the esophagus. Systemic therapies that include novel, targeted biologic agents have the potential of addressing subepithelial remodeling. Esophageal dilation remains a useful, adjunctive therapeutic maneuver in symptomatic adults with esophageal stricture. As novel treatments emerge, it is essential that therapeutic endpoints account for the fundamental contributions of esophageal remodeling to overall disease activity. PMID:24813517

Purpose: To retrospectively analyze the outcomes and prognostic factors of cervical esophageal squamous cell carcinoma (SCC) treated with intensity modulated radiation therapy (IMRT). Methods: Thirty-seven patients with cervical esophageal SCC treated with IMRT were analyzed retrospectively. They received 54–66 Gy in 27–32 fractions. Nineteen patients received concurrent (n=12) or sequential (n=7) platinum-based two drugs chemoradiotherapy. Overall survival (OS), local control rates (LCR) and prognostic factors were evaluated. Acute toxicities and patterns of first failures were observed. Results: The median follow-up was 46 months for alive patients. The l-, 3-, 4- and 5-year OS of the all patients were 83.8%, 59.1%,more » 47.5% and 32.6% respectively. The median survival time was 46 months. The l-, 3-,4- and 5-year LCR were 82.9%, 63.0%, 54.5% and 54.5%, respectively. Univariate and Multivariate analysis all showed that size of GTV was an independent prognostic factor (p=0.033, p=0.039). There were no patients with Grade 3 acute radiation esophagitis and Grade 2–4 acute pneumonitis. The local failure accounted for 70.0% of all treatment-related failures. Conclusion: IMRT is safe and effective in the treatment of cervical esophageal squamous cell carcinoma. Size of GTV is an independent prognostic factor. Local failure still remains the main reason of treatment failures. The authors declare no conflicts of interest in preparing this article.« less

Potential of Proton Therapy to Reduce Acute Hematologic Toxicity in Concurrent Chemoradiation Therapy for Esophageal Cancer.

Radiation therapy dose escalation using a simultaneous integrated boost (SIB) is predicted to improve local tumor control in esophageal cancer; however, any increase in acute hematologic toxicity (HT) could limit the predicted improvement in patient outcomes. Proton therapy has been shown to significantly reduce HT in lung cancer patients receiving concurrent chemotherapy. Therefore, we investigated the potential of bone marrow sparing with protons for esophageal tumors. Twenty-one patients with mid-esophageal cancer who had undergone conformal radiation therapy (3D50) were selected. Two surrogates for bone marrow were created by outlining the thoracic bones (bone) and only the body of the thoracic vertebrae (TV) in Eclipse. The percentage of overlap of the TV with the planning treatment volume was recorded for each patient. Additional plans were created retrospectively, including a volumetric modulated arc therapy (VMAT) plan with the same dose as for 3D50; a VMAT SIB plan with a dose prescription of 62.5 Gy to the high-risk subregion within the planning treatment volume; a reoptimized TV-sparing VMAT plan; and a proton therapy plan with the same SIB dose prescription. The bone and TV dose metrics were recorded and compared across all plans and variations with respect to PTV and percentage of overlap for each patient. The 3D50 plans showed the highest bone mean dose and TV percentage of volume receiving ≥30 Gy (V 30Gy ) for each patient. The VMAT plans irradiated a larger bone V 10Gy than did the 3D50 plans. The reoptimized VMAT62.5 VT plans showed improved sparing of the TV volume, but only the proton plans showed significant sparing for bone V 10Gy and bone mean dose, especially for patients with a larger PTV. The results of the present study have shown that proton therapy can reduced bone marrow toxicity. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

An association between eosinophilic esophagitis (EoE) and esophageal motility disorders has been described in small studies. The aim of this study was to describe the prevalence of esophageal motor disorders in a large cohort of adults with EoE and examine whether an association exists between esophageal dysmotility and dysphagia. A retrospective review of esophageal manometry studies in adult EoE patients was performed. Tracings were reviewed for abnormalities including nutcracker esophagus and ineffective swallows, defined as low amplitude peristalsis (<30 mmHg) or non-propagating contractions. Ineffective esophageal motility (IEM) was categorized as mild (30-40% ineffective swallows), moderate (50-60% ineffective swallows), and severe (≥70% ineffective swallows). Dysphagia was graded on a 0-3 scale for frequency and severity. Seventy-five tracings from EoE patients were reviewed (85% male, mean age 41 ± 12 years). IEM was identified in 25 patients and categorized as mild (n = 13), moderate (n = 6), and severe (n = 6). Nutcracker esophagus was found in three patients. There was no significant difference in eosinophil count among the motility groups: normal 46.5 ± 3.1, mild IEM 56.9 ± 36.9, moderate IEM 45.5 ± 23.7, severe IEM 34.3 ± 12.6 (P = 0.157). In this cohort of EoE patients, the majority had normal esophageal motility studies, although a subset of these patients had some esophageal dysmotility. It is unlikely that esophageal dysmotility is a major contributing factor to dysphagia, although it is reasonable to consider esophageal manometry testing in EoE patients to identify potential abnormalities of the smooth muscle esophagus.

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.

Purpose: To assess the usefulness of oral glutamine to prevent radiochemotherapy-induced esophagitis in patients with lung cancer, and to determine the dosimetric parameter predictive of esophagitis. Methods and Materials: Seventy-five patients were enrolled; 34.7% received sequential radiochemotherapy, and 65.3% received concomitant radiochemotherapy. Every patient received prophylactic glutamine powder in doses of 10 g/8 h. Prescribed radiation doses were 45-50 Gy to planning target volume (PTV)1 (gross tumor volume plus wide margins) and 65-70 Gy to PTV2 (reduced margins). The primary endpoint was the incidence of Grade 2 or greater acute esophagitis. Results: No patient experienced glutamine intolerance or glutamine-related toxicity.more » Seventy-three percent of patients who received sequential chemotherapy and 49% of those who received concomitant chemotherapy did not present any form of esophagitis. V50 was the dosimetric parameter with better correlation between esophagitis and its duration. A V50 of {<=}30% had a 22% risk of esophagitis Grade {>=}2, which increased to 71% with a V50 of >30% (p = 0.0009). Conclusions: The use of oral glutamine may have an important role in the prevention of esophageal complications of concomitant radiochemotherapy in lung cancer patients. However, randomized trials are needed to corroborate that effect. V50 is the dosimetric parameter with better correlation with esophagitis grade and duration.« less

Infectious mononucleosis is a clinical syndrome most commonly associated with primary Epstein-Barr virus infection. The majority of patients with infectious mononucleosis recovers without apparent sequelae. However, infectious mononucleosis may be associated with several acute complications. In this report we present a rare case of esophageal rupture that has never been described in the literature before. We present the case of an 18-year-old Caucasian man affected by severe infectious mononucleosis complicated by fulminant hepatic failure, splenic rupture and esophageal necrosis. Although primary Epstein-Barr virus infection is rarely fatal, fulminant infection may occur - in this case leading to hepatic failure, splenic rupture and esophageal necrosis, subsequently making several surgical interventions necessary. We show here that infectious mononucleosis is not only a strictly medical condition, but can also lead to severe surgical complications.

We aim to evaluate whether different definitions of esophagus (DEs) impact on the esophageal toxicity prediction for esophageal cancer (EC) patients administered intensity-modulated radiation therapy with simultaneous integrated boost (SIB-IMRT) vs. standard-dose IMRT (SD-IMRT). The esophagus for 21 patients diagnosed with primary EC were defined in the following four ways: the whole esophagus, including the tumor (ESO whole ); ESO whole within the treatment field (ESO infield ); ESO infield , excluding the tumor (ESO infield-tumor ) and ESO whole , excluding the tumor (ESO whole-tumor ). The difference in the dose variation, acute esophageal toxicity (AET) and late esophageal toxicity (LET) of four DEs were compared. We found that the mean esophageal dose for ESO whole , ESO infield , ESO infield-tumor and ESO whole-tumor were increased by 7.2 Gy, 10.9 Gy, 4.6 Gy and 2.0 Gy, respectively, in the SIB-IMRT plans. Radiobiological models indicated that a grade ≥ 2 AET was 2.9%, 3.1%, 2.2% and 1.6% higher on average with the Kwint model and 14.6%, 13.2%, 7.2% and 3.4% higher with the Wijsman model for the four DEs. A grade ≥ 3 AET increased by 4.3%, 7.2%, 4.2% and 1.2%, respectively. Additionally, the predicted LET increased by 0.15%, 0.39%, 1.2 × 10 -2 % and 1.5 × 10 -3 %. Our study demonstrates that different DEs influence the esophageal toxicity prediction for EC patients administered SIB-IMRT vs. SD-IMRT treatment.

Introduction We present a patient who presented to the ICU after successful resuscitation from cardiac arrest who was subsequently diagnosed with AEN. Case Presentation A 66-year-old female presented after cardiac arrest in which return of spontaneous circulation was achieved within 7 minutes after the initiation of CPR. She was intubated on the scene and found to have coffee ground emesis in her bathroom when found unresponsive. Due to the hemodynamically significant GI bleed, patient was started on IV proton pump inhibitor, octreotide, and levophed. Subsequent endoscopy showed diffuse severe mucosal changes characterized by blackness, erythema, friability, granularity, inflammation, and decreased vascular pattern in the middle third of the esophagus and in the lower third of the esophagus. Discussion AEN is a rare syndrome with a prevalence ranging from 0.001 to 0.2% of EGD. This patient is especially rare as this patient was female and had AEN in the middle esophagus along with lower esophagus. The pathophysiology in this patient is hypothesized that she had cardiac arrest secondary to acute upper GI hemorrhage. Subsequent low-flow state (cardiac arrest) in addition to being in the setting of severe alcohol abuse led to esophageal necrosis. PMID:28706745

Endoscopic submucosal dissection (ESD) for superficial esophageal cancer is sometimes extensive, and in our experience, patients not infrequently present with dysphagia after ESD even in the absence of esophageal stricture. The aim of this study was to evaluate esophageal motility using high-resolution manometry (HRM) in patients with and without dysphagia after extensive circumferential ESD. HRM was performed in a total of 52 patients who had undergone ESD for superficial esophageal cancer and a mucosal defect after ESD exceeded more than two-thirds of the esophageal circumference. The frequency and type of esophageal dysmotility and the relationship between esophageal motility and dysphagia were evaluated. Esophageal dysmotility was observed in 13 patients (25%): jackhammer esophagus in 4, esophagogastric junction outflow obstruction in 4, absent contractility in 2, and distal esophageal spasm, ineffective esophageal motility, and fragmented peristalsis in 1 patient each. Of the 22 patients with dysphagia after ESD, 9 (41%) had esophageal dysmotility. Of the 30 patients without dysphagia after ESD, 4 (13%) had esophageal dysmotility. The relationship between dysmotility and dysphagia was significant (p = 0.025). Esophageal dysmotility exists in approximately one-quarter of patients after extensive circumferential ESD, which is associated with dysphagia in the absence of esophageal stricture. © 2018 S.

This retrospective study of a large cohort of patients with UGIB used logistic regression analyses to evaluate the platelet count, aspartate aminotransferase (AST) to platelet ratio index (APRI), AST to alanine aminotransferase (ALT) ratio (AAR) and Lok index (all non-invasive blood markers) as predictors of variceal bleeding in (1) all patients with UGIB and (2) patients with cirrhosis and UGIB. 2233 patients admitted for UGIB were identified; 1034 patients had cirrhosis (46%) and of these, 555 patients (54%) had acute UGIB due to esophageal varices. In all patients with UGIB, the platelet count (cut-off 122,000/mm(3)), APRI (cut-off 5.1), AAR (cut-off 2.8) and Lok index (cut-off 0.9) had area under the curve (AUC)s of 0.80 0.82, 0.64, and 0.80, respectively, for predicting the presence of varices prior to endoscopy. To predict varices as the culprit of bleeding, the platelet count (cut-off 69,000), APRI (cut-off 2.6), AAR (cut-off 2.5) and Lok Index (0.90) had AUCs of 0.76, 0.77, 0.57 and 0.73, respectively. Finally, in patients with cirrhosis and UGIB, logistic regression was unable to identify optimal cut-off values useful for predicting varices as the culprit bleeding lesion for any of the non-invasive markers studied. For all patients with UGIB, non-invasive markers appear to differentiate patients with varices from those without varices and to identify those with a variceal culprit lesion. However, these markers could not distinguish between a variceal culprit and other lesions in patients with cirrhosis. Copyright © 2016 American Federation for Medical Research.

Esophageal manometry is the clinically available method to estimate pleural pressure, thus enabling calculation of transpulmonary pressure (Pl). However, many concerns make it uncertain in which lung region esophageal manometry reflects local Pl. To determine the accuracy of esophageal pressure (Pes) and in which regions esophageal manometry reflects pleural pressure (Ppl) and Pl; to assess whether lung stress in nondependent regions can be estimated at end-inspiration from Pl. In lung-injured pigs (n = 6) and human cadavers (n = 3), Pes was measured across a range of positive end-expiratory pressure, together with directly measured Ppl in nondependent and dependent pleural regions. All measurements were obtained with minimal nonstressed volumes in the pleural sensors and esophageal balloons. Expiratory and inspiratory Pl was calculated by subtracting local Ppl or Pes from airway pressure; inspiratory Pl was also estimated by subtracting Ppl (calculated from chest wall and respiratory system elastance) from the airway plateau pressure. In pigs and human cadavers, expiratory and inspiratory Pl using Pes closely reflected values in dependent to middle lung (adjacent to the esophagus). Inspiratory Pl estimated from elastance ratio reflected the directly measured nondependent values. These data support the use of esophageal manometry in acute respiratory distress syndrome. Assuming correct calibration, expiratory Pl derived from Pes reflects Pl in dependent to middle lung, where atelectasis usually predominates; inspiratory Pl estimated from elastance ratio may indicate the highest level of lung stress in nondependent "baby" lung, where it is vulnerable to ventilator-induced lung injury.

Lung cancer survival is poor, and radiation therapy patients often suffer serious treatment side effects. The esophagus is particularly sensitive leading to acute radiation-induced esophageal damage (ARIED). We investigated the feasibility of optical coherence tomography (OCT) for minimally invasive imaging of the esophagus with high resolution (10 μm) to detect ARIED in mice. Thirty mice underwent cone-beam computed tomography imaging for initial setup assessment and dose planning followed by a single-dose delivery of 4.0, 10.0, 16.0, and 20.0 Gy on 5.0-mm spots, spaced 10.0 mm apart in the esophagus. They were repeatedly imaged using OCT up to three months postirradiation. We compared OCT findings with histopathology obtained three months postirradiation qualitatively and quantitatively using the contrast-to-background-noise ratio (CNR). Histopathology mostly showed inflammatory infiltration and edema at higher doses; OCT findings were in agreement with most of the histopathological reports. We were able to identify the ARIED on OCT as a change in tissue scattering and layer thickness. Our statistical analysis showed significant difference between the CNR values of healthy tissue, edema, and inflammatory infiltration. Overall, the average CNR for inflammatory infiltration and edema damages was 1.6-fold higher and 1.6-fold lower than for the healthy esophageal wall, respectively. Our results showed the potential role of OCT to detect and monitor the ARIED in mice, which may translate to humans.

To evaluate the functional aspect of esophageal motility in healthy subjects and in patients who were referred for esophageal function testing using multichannel intraluminal impedance-esophageal manometry (MII-EM), and to assess the clinical utility of MII-EM. From September 2003 to January 2004, we performed the MII-EM on healthy volunteers and all the patients who were referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. We analyzed the results, the impedance and the manometric findings. Some of the subjects had additional ambulatory 24-h pH study performed to diagnose gastroesophageal reflux disease (GERD). Among 89 studied subjects, the MII-EM findings showed normal esophageal motility in 50 (56.17%), ineffective esophageal motility (IEM) in 17 (19.10%), nutcracker esophagus in 7 (7.86%), achalasia in 4 (4.49%), and scleroderma esophagus in 11 (12.35%) cases. The completeness and the speed of bolus transit were in the order of nutcracker esophagus, normal manometry and IEM. Some of the swallows showing normal manometry and IEM had incomplete transit. In the achalasia and scleroderma esophagus, almost all the swallows had incomplete transit. The body amplitudes were higher for the swallows with complete transit than for the swallows with incomplete transit. There was not a significant difference in the manometric and impedance findings between the subjects with and without GERD. MII-EM is a useful tool in assessing the esophageal function in the patients having esophageal motility abnormality. The primary factors influencing the bolus transit are the amplitude of the esophageal body and normal peristalsis.

The aim of this work was to study the correlation between the reflux timing and the presence of esophagitis, an inconstant but serious complication of gastro-esophageal reflux (GER). The hypothesis was that reflux occurring late after meal can be incriminated more than early reflux in esophagitis genesis. 32 children with GER (mean age = 10.5 months, 2 to 30 months) had esophagoscopy and scintigraphy in the same week. The children were classified in two groups according to esophagoscopy: group 1 (n = 18) no esophagitis, group 2 (n = 14) esophaqgitis. The scintigraphy involved the ingestion of 0.5 mCi Tc-99mmore » sulfur colloid milk mixture, followed by esophageal and gastric activity recording (one image per minute for 1 hour). The reflux was assessed from contrast enhanced images and esophageal time activity curves. Reflux intensity was quantitated by reflux index (Re). Mean reflux time was calculated as the mean esophageal activity peaks time (t-bar). Finally a composite parameter was calculated as the mean reflux time weighted by the relative intensity of each reflux peak (t-barw). Re was not found to be different between the two groups. t-bar was significantly higher in group 2: t-bar = 29.6 +- 3.0 mn (mean +- SD) than in group 1: t-bar = 24.5 +- 6.8 mn; rho <0.02. The difference between the two groups was enhanced by intensity weighting: group 1: t-barw = 16.6 +- 6.3 mn, group 2: t-barw = 33.5 +- 7.1 mn rho <0.001. t-barw value was not correlated to esophagitis grade. These results suggest that late reflux is more likely responsible of esophagitis.« less

Background & Aims Normal responses of the upper esophageal sphincter (UES) and esophageal body to liquid reflux events prevent esophagopharyngeal reflux and its complications, but abnormal responses have not been characterized. We investigated whether patients with supra-esophageal reflux disease (SERD) have impaired UES and esophageal body responses to simulated reflux events. Methods We performed a prospective study of 25 patients with SERD (19–82 y old, 13 female) and complaints of regurgitation and supra-esophageal manifestations of reflux. We also included 10 patients with gastroesophageal reflux disease (GERD; 32–60 y old, 7 female) without troublesome regurgitation and supra-esophageal symptoms and 24 healthy asymptomatic individuals (controls; 19–49 y old, 13 female). UES and esophageal body pressure responses, along with luminal distribution of infusate during esophageal rapid and slow infusion of air or liquid, were monitored by concurrent high-resolution manometry and intraluminal impedance. Results A significantly smaller proportion of patients with SERD had UES contractile reflexes in response to slow esophageal infusion of acid than controls or patients with GERD. Only patients with SERD had abnormal UES relaxation responses to rapid distension with saline. Diminished esophageal peristaltic contractions resulted in esophageal stasis in patients with GERD or SERD. Conclusions Patients with SERD and complaints of regurgitation have impaired UES and esophageal responses to simulated liquid reflux events. These patterns could predispose them to esophagopharyngeal reflux. PMID:26188682

The pathophysiology of dysphagia in patients with eosinophilic esophagitis (EoE) is unknown but may be related to abnormal esophageal motor function. Symptoms rarely occur during stationary esophageal manometry, so it has been difficult to establish an association between symptoms and motor events. Our aim was to evaluate esophageal motor function in children with EoE with the use of stationary manometry and ambulatory prolonged esophageal manometry and pH-metry (PEMP). PEMP was performed in children with EoE and compared with controls and children with gastroesophageal reflux disease (GERD). Peristalsis was considered effective when the esophageal contractions had a normal amplitude and propagation. Results are expressed as mean+/-s.e. Seventeen patients with EoE, 13 with GERD, and 11 controls were studied. Values are expressed as mean+/-s.e. Stationary manometry identified abnormal peristalsis in 41% of children with EoE. During PEMP, children with EoE had an increased number of isolated (16.7+/-3.8 vs. 9.5+/-1.6 vs. 6.5+/-1.1; P<0.03) and high-amplitude contractions (4.1+/-1.2 vs. 1.8+/-0.8 vs. 0.1+/-0.1; P<0.03), and higher percentage ineffective peristalsis both during fasting (70.5%+/-2.5 vs. 57.8%+/-3.0 vs. 53.8%+/-1.9; P<0.05) and during meals (68.4+/-3.4 vs. 55.3+/-2.8 vs. 48.1+/-2.8; P<0.05) when compared with children with GERD and controls. Thirteen patients with EoE experienced 21 episodes of dysphagia, and all correlated with simultaneous abnormal motor function. PEMP allowed the detection of ineffective peristalsis in children with EoE. Symptoms observed in children with EoE may be related to esophageal motor dysfunction.

The hepatic cirrhosis has as one of the main morbid-mortality causes, the portal hypertension with the development of esophageal varices, the possibility of a digestive hemorrhage and worsening of hepatic insufficiency. It is important to identify causal predictive or aggravating factors and if possible to prevent them. In the last years, it has been observed the association of esophageal motor disorders and gastro-esophageal reflux in cirrhotic patients with esophageal varices. To study the prevalence of the esophageal motility disorders and among them, the ineffective esophageal motility, in patients with hepatic cirrhosis and esophageal varices, without previous endoscopic therapeutic and the predictive factors. Prospectively, it has been evaluate 74 patients suffering from liver cirrhosis and esophagic varices, without previous endoscopic treatment. All of them were submitted to a clinical protocol, esophageal manometry and 55 patients also held the ambulatory esophageal pHmetry. Esophageal motility disorders have been found in 44 patients (60%). The most prevalent was the ineffective esophageal motility, observed in 28%. The abnormal reflux disease was diagnosed through the pHmetry in 35% of the patients. There were no correlation between the manometrical abnormality in general and the ineffective esophageal motility in particular and the esophageal or gastroesophageal reflux disease symptoms, the abnormal reflux, the disease seriousness, the ascites presence and the gauge of the varices. The majority of cirrhotic patients with non-treated esophageal varices present esophageal motor disorders. No predictive factor was found. The clinical relevance of these findings need more researches in the scope to define the real meaning of theses abnormalities.

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.

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

Esophageal motility abnormalities, as measured by conventional manometry (CM), are non-specific in the majority of patients with eosinophilic esophagitis (EoE). Moreover, the study of CM is limited by poor interobserver agreement. The aims of the present study were: (i) to assess the esophageal patterns in EoE by a topographic analysis of high-resolution manometry (HRM) data; and (ii) to establish a relationship between motility abnormalities and symptoms of EoE, such as dysphagia and bolus impaction. All adult patients with EoE diagnosed according to histological criteria, and controls with gastroesophageal reflux disease symptoms and dysphagia, were included. HRM was done in EoE patients and controls. For the analysis of data, the Chicago classification was followed. HRM was performed in 21 patients with EoE, as well as in 21 controls. Of the 21 patients with EoE, 10 (48%) showed pan-esophageal pressurization, six (28%) showed peristaltic dysfunction, and in five cases (24%), HRM was normal. There was no pan-esophageal pressurization in controls. Nine of 10 patients with pan-esophageal pressurization required endoscopic bolus removal (P < 0.05); none had obstructive endoscopy findings. The most frequent esophageal motor abnormality measured by HRM was a pan-esophageal pressurization. Bolus impaction in patients with EoE was associated with pan-esophageal pressurization. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

This article focuses on esophageal replacement as a surgical option for pediatric patients with end-stage esophageal disease. While it is obvious that the patient׳s own esophagus is the best esophagus, persisting with attempts to retain a native esophagus with no function and at all costs are futile and usually detrimental to the overall well-being of the child. In such cases, the esophagus should be abandoned, and the appropriate esophageal replacement is chosen for definitive reconstruction. We review the various types of conduits used for esophageal replacement and discuss the unique advantages and disadvantages that are relevant for clinical decision-making.

To observe the safety of selective dose boost to the pre-treatment high (18)F-deoxyglucose (FDG) uptake areas of the esophageal GTV. Patients with esophageal squamous cell carcinoma were treated with escalating radiation dose of 4 levels, with a simultaneous integrated boost (SIB) to the pre-treatment 50% SUVmax area of the primary tumor. Patients received 4 monthly cycles of cisplatin and fluorouracil. Dose-limiting toxicity (DLT) was defined as any Grade 3 or higher acute toxicities causing continuous interruption of radiation for over 1 week. From April 2012 to February 2014, dose has been escalated up to LEVEL 4 (70Gy). All of the 25 patients finished the prescribed dose without DLT, and 10 of them developed Grade 3 acute esophagitis. One patient of LEVEL 2 died of esophageal hemorrhage within 1 month after completion of radiotherapy, which was not definitely correlated with treatment yet. Late toxicities remained under observation. With median follow up of 8.9months, one-year overall survival and local control was 69.2% and 77.4%, respectively. Dose escalation in esophageal cancer based on (18)FDG-PET/CT has been safely achieved up to 70Gy using the SIB technique. Acute toxicities were well tolerated, whereas late toxicities and long-term outcomes deserved further observation. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Transient lower esophageal sphincter relaxation and esophageal motor response.

Schneider, Joachim H; Küper, Markus A; Königsrainer, Alfred; Brücher, Björn L D M

2010-04-01

Gastroesophageal reflux is caused by transient lower esophageal sphincter relaxations (TLESRs) in healthy individuals and in most patients with gastroesophageal reflux disease (GERD). Refluxate is normally propelled by pharyngeally induced swallowing events, but TLESRs may also be accompanied by retrograde esophageal motor responses (EMRs). These contractions have not previously been investigated and their effect on esophageal clearance is not known. The aim of this study was to assess the frequency of EMRs after TLESR in healthy individuals and GERD patients and to develop an animal model for further investigation of EMRs. The frequency of TLESRs and esophageal body contractions after TLESRs was assessed using ambulatory manometry in five healthy individuals and five GERD patients. An animal model was developed for reproducible provocation of TLESRs and subsequent EMRs. Patients with GERD have significantly more TLESRs than healthy individuals. However, post-TLESR EMRs were not more frequent in the GERD group. All post-TLESR EMRs presented as simultaneous contractions of the esophagus. The feline model allowed reproducible initiation of the esophageal motor response after TLESR, showing that EMRs can be induced by external mechanoreceptor stimulation simultaneously with LES relaxation. This experimental design imitates the conditions after fundoplication in humans. The study demonstrated that GERD patients have significantly more TLESRs in comparison with healthy individuals, but these were only incidental to EMRs. Further research is needed to improve our understanding of esophageal motility disorders. The animal model presented offers a feasible tool for investigating TLESR-induced esophageal motility.

The majority of normal-tissue complication probability (NTCP) models for acute esophageal toxicity (AET) in advanced stage non-small cell lung cancer (AS-NSCLC) patients treated with (chemo-)radiotherapy are based on three-dimensional conformal radiotherapy (3D-CRT). Due to distinct dosimetric characteristics of intensity-modulated radiation therapy (IMRT), 3D-CRT based models need revision. We established a multivariable NTCP model for AET in 149 AS-NSCLC patients undergoing IMRT. An established model selection procedure was used to develop an NTCP model for Grade ⩾2 AET (53 patients) including clinical and esophageal dose-volume histogram parameters. The NTCP model predicted an increased risk of Grade ⩾2 AET in case of: concurrent chemoradiotherapy (CCR) [adjusted odds ratio (OR) 14.08, 95% confidence interval (CI) 4.70-42.19; p<0.001], increasing mean esophageal dose [Dmean; OR 1.12 per Gy increase, 95% CI 1.06-1.19; p<0.001], female patients (OR 3.33, 95% CI 1.36-8.17; p=0.008), and ⩾cT3 (OR 2.7, 95% CI 1.12-6.50; p=0.026). The AUC was 0.82 and the model showed good calibration. A multivariable NTCP model including CCR, Dmean, clinical tumor stage and gender predicts Grade ⩾2 AET after IMRT for AS-NSCLC. Prior to clinical introduction, the model needs validation in an independent patient cohort. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Esophageal involvement in systemic sclerosis (SSc) carries significant morbidity and is empirically managed with domperidone, albeit with questionable efficacy. The oral 5-HT1A receptor agonist buspirone may enhance esophageal peristalsis and lower esophageal sphincter (LES) function in healthy volunteers. We aimed to test the hypothesis that buspirone may exert a beneficial acute effect on esophageal motor dysfunction in symptomatic patients with SSc. Twenty consecutive patients with SSc reporting esophageal symptoms underwent high-resolution manometry before and 30 minutes after administration of buspirone (10 mg). Ten other patients received domperidone (10 mg) and served as control group. Changes in LES resting and residual pressure, amplitude, duration, and velocity of distal esophageal body contractions were examined. Esophageal hypomotility and hypotensive LES was found in 63% and 67% of patients, respectively. Demographic and clinical characteristics, including baseline manometric parameters, were comparable between groups. Resting pressure of LES increased after buspirone from 9.42 ± 2.6 to 11.53 ± 3.4 mmHg (p = 0.0002 by paired t-test), but not after domperidone; a trend for increase of amplitude of contractions was also observed after buspirone (p = 0.09). Comparison of the individual changes revealed that buspirone was superior to domperidone in enhancing LES pressure ( + 2.11 ± 2.0 versus -0.45 ± 2.3 mmHg, p = 0.006). No significant effects of either drug were noted on other examined parameters of esophageal function. The beneficial acute effect of buspirone on impaired LES function associated with SSc suggests a role of 5-HT1A receptor-mediated interactions in these patients. Prospective studies to examine whether buspirone is of long-term therapeutic value for SSc-associated esophageal disease are warranted.

To determine clinical factors for predicting the frequency and severity of esophageal stenosis associated with tumor regression in radiotherapy for esophageal cancer. 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. 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). 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.

To observe the effect of Shaogen Decoction (SGD) for the prevention and treatment of acute radiation esophagitis (ARE). Sixty patients with breast tumor receiving chemo/radiotherapy were assigned to two groups, the SGD group and the control group. The patients in the SGD group were administered with SGD, a Chinese preparation consisted of Radix Sophorae tonkinensis 10 g, Radix Paeoniae Alba 30 g, Radix Scrophulariae 15 g, Rhizoma Bletillae 15 g, Radix Notoginseng 3 g, etc., starting from the initial day of radiotherapy, 10 mL, thrice a day, while in case of 2nd or over 2nd grade ARE occurred, it was changed to 10 mL, every 2 h, medicated by keeping in mouth and slowly swallowed followed with 5-min forbiddance of food and water. The patients in the control group were treated, in case of 2nd or over 2nd grade ARE occurred, with antibiotic drugs (such as cefuroxime 4.5 g) and hormone (dexamethasone 5 mg) by intravenous infusion for 7 days. The incidence, happening time, and retaining time of ARE, therapeutic effect on it, as well as the proportion of patients for whom antibiotics and hormone were used in the two groups were observed. The incidence of 2nd or over 2nd grade ARE in the SGD group and the control group was 33.33% and 63.33%, respectively, that in the former was significantly lower (chi2 = 5.406, P<0.05). Different degrees of acute esophageal toxic response occurred in both groups, initially presenting at 19.8 +/- 7.4 days in the SGD group and at 20.2 +/- 9.6 days in the control group after radiotherapy, that was delayed in the former (t=2.130, P<0.05). Clinical symptom of ARE retained for 56.4 +/- 19.5 days and 58.2 +/- 15.0 days in the two groups, respectively, it was shorter in the SGD groups (t=2.441, P<0.05). Moreover, the proportion of patients for whom antibiotics and hormone were used in the SGD group was less. SGD acted, in coordinating with chemo-radiotherapy, to reduce the incidence, retard the happening and shorten the retaining time of 2nd or

Radiation therapy is one of the standard therapeutic modalities for esophageal cancer, achieving its main antitumor efficacy through DNA damage. However, accumulating evidence shows that radiotherapy can substantially alter the tumor microenvironment, particularly with respect to its effects on immune cells. We hypothesized that the immune response elicited by radiotherapy may be as important as the radiation itself for successful treatment. More specifically, immunomodulatory cytokines may enhance the effectiveness of radiotherapy. To investigate this hypothesis, we measured changes in the serum interferon-gamma (IFN- γ ) and interleukin-2 (IL-2) concentrations during radiotherapy and compared these modifications with outcomes. We found that serum concentrations of IL-2 and IFN- γ were positively associated with local response to radiotherapy in esophageal cancer. More generally, the intensity of the radiotherapy-elicited immune response was positively associated with local response to radiotherapy in esophageal cancer. Changes in serum IL-2 and IFN- γ concentrations were further associated with increased risks of acute hematologic toxicity and acute organ toxicity of the esophagus, lung, and skin. These results suggest that deciphering the mechanisms of radiotherapy-elicited immune response may help in the development of therapeutic interventions that would enhance the efficacy of radiotherapy and convert some ineffective responses to effective responses.

Esophagitis and Barrett's esophagus are linked to esophageal squamous cell carcinoma and adenocarcinoma, respectively. However, the underlying mechanisms are still unclear. This study analyzed the expression levels of and correlation between PLCE1 and PRKCA in human esophagitis, carcinogen NMBA-induced rat esophagus, PLCE1 genetic deficient mouse esophageal epithelial tissues and human esophageal cancer cell line, integrated with Online oncology data sets. We found that the expression levels of both PLCE1 and PRKCA were significantly elevated in human esophagitis, esophageal squamous cell carcinoma, Barrett's esophagus, esophageal adenocarcinoma and in NMBA-treated rat esophageal epithelia. However, PRKCA and cytokines were significantly downregulated in PLCE1-deficient mouse esophageal epithelia, and knockdown of PLCE1 in human esophageal cancer cells led to reduction of PRKCA and cytokines. Finally, high expression of both PLCE1 and PRKCA is significantly associated with poor outcomes of the patients with esophageal cancers. In conclusion, this study defined the initiation and progression of esophageal inflammation and malignant transformation, in which the positive correlation of PLCE1 and PRKCA exhibits critical clinical significance.

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.

Esophageal high-resolution manometry (HRM) is replacing conventional manometry in the clinical evaluation of patients with esophageal symptoms, especially dysphagia. The introduction of HRM gave rise to new objective metrics and recognizable patterns of esophageal motor function, requiring a new classification scheme: the Chicago classification. HRM measurements are more detailed and more easily performed compared to conventional manometry. The visual presentation of acquired data improved the analysis and interpretation of esophageal motor function. This led to a more sensitive, accurate, and objective analysis of esophageal motility. In this review we discuss how HRM changed the way we define and categorize esophageal motility disorders. Moreover, we discuss the clinical applications of HRM for each esophageal motility disorder separately.

To evaluate dosimetric predictors of acute esophagitis (AE) and clinical outcome of patients with non-small-cell lung cancer (NSCLC) receiving reirradiation. Seventeen patients with NSCLC received reirradiation to the lung tumors/mediastinum, while immobilized in stereotactic body frame (SBF). CT simulation and hypofractionated three-dimensional radiotherapy were used. Two axial segments of esophagus contours merged together were defined as esophagus disc (ED). For each ED, the percentage (%) of the volume of esophageal circumference treated to % of prescribed dose (PD) was assessed. Number of EDs with 50% or any % of volume (V) of esophageal circumference receiving more than or equal to (>/=) 50%, 80%, and 100% of PD (50% V >/=50% PD; 50% V >/=80% PD; any % V >/=100% PD) were calculated. These dosimetric variables and the length of the esophagus within the radiation therapy (RT) port were correlated with AE using exact Wilcoxon test. A median RT dose was 32 Gy with a median fraction size of 4 Gy. Eleven of 13 patients presenting with pain and/or shortness of breath had complete or partial resolution of symptoms. Median survival time from the start of reirradiation in SBF until death was 5.5 months. AE was observed in 7 patients and resolved within 3 months of RT completion. No Grade 3 or higher events were noticed. The length of the esophagus within RT port did not predict for AE (p = 0.71). However, an increased number of EDs predicted for AE for the following dosimetric variables: 50% V >/=50% PD (p = 0.023), 50% V >/=80% PD (p = 0.047), and any % V >/=100% PD (p = 0.004). Patients with at least 2 EDs receiving >/=100% PD to any % V of circumference had AE compared to those with zero EDs. Reirradiation using hypofractionated three-dimensional radiotherapy and SBF immobilization is an effective strategy for palliation of symptoms in selected patients with recurrent NSCLC. The length of the esophagus in the RT field does not predict for AE. However, an increasing

To explore the clinical manifestations and treatments of retro-esophageal space abscess. The clinical data of 27 cases with retro-esophageal space abscess were analyzed retrospectively. Twenty-one cases (77. 78%) were secondary to acute injury of esophageal meatus caused by foreign bodies. 2 cases (7. 41%)were secondary to old foreign body infection in retro-esophageal space, 3 cases (11. 11%) after secondary to pharyngeal abscess, and 1 case (3. 70%) was unknown to etiology. All patients were confirmed by sectional medicalimageology. Six cases(Conservation group, C group) were treated conservatively and 6 cases (Oropharyngeal incision group, OI group) were performed with oropharyngeal incision drainage. 15 cases(Extra-neck incision group, ENI group)were performed with extra-neck incision and vacuum sealing drainage. In C group, 6 cases were cured with conservative therapy and the average hospital stay was 15. 6 days. In OI group, 5 cases were healed with oropharyngeal drainage but aspiration pneumonia complicated with septic shock occurred in 2 cases, and 1 case dead from septic shock secondary to mediastinum and lung abscess. The average hospital stay was 18. 8 days. In ENI group, 15 patients were cured with extra-neck drainage without complication and the average hospital stay was 9. 5 days. The main causes of retro-esophageal space abscess are foreign body injury of upper esophagus and remnant of retro-esophageal space. Sectional medicalimageology can be of important value of diagnosis and treatment for displaying the retro-esophageal space abscess and other deep cervical fascia space sufficiently. Incision and vacuum sealing drainage via extra-neck is an effective therapy while oropharyngeal drainage is less effective and is not advocated as a primary treatment because of aspiration pneumonia complication . Conservative cure is a choice for patients without dyspnoea and background diseases, and it is necessary to recognize and treat severe complications early.

Photodynamic therapy (PDT) has been used in recent years to deal with fungal infections because of the prevalence of fungi resistance to drugs. However, PDT for gastrointestinal fungal infection has not been reported. This study was conducted to assess the potential of PDT to deal with esophageal candidiasis. Two male patients with histological evidence of esophageal candidiasis coexisting with esophageal cancer were included in this retrospective study. Both patients were treated with PDT. This treatment was repeated at least 1month after the initial PDT if the patient still had residual cancer or esophageal candidiasis. Short-term efficacy was evaluated on the basis of endoscopy and histology findings. Further follow-up data were obtained from endoscopy results or telephone conversation. The esophageal candidiasis located 21-24cm and 25-28cm from the incisors of case 1 reached complete remission after one and two PDT sessions, respectively. The esophageal cancer coexisting with esophageal candidiasis located 21-24cm from the incisors reached complete remission after two PDT sessions. No recurrence was found at a 14-month follow-up. The esophageal cancer located 30-35cm from the incisors reached partial response after three PDT sessions. Both of the esophageal candidiasis and the coexisting esophageal cancer at 23-26cm from the incisors of case 2 reached complete remission and the esophageal cancer at 34-37cm from the incisors reached complete remission after one PDT session. No recurrence was found at a 24-month follow-up. There were no serious adverse events found in either of the two cases. Results of this preliminary study indicate that PDT may be a potential method to deal with esophageal candidiasis. Copyright © 2013 Elsevier B.V. All rights reserved.

For neck and upper thoracic esophageal carcinoma, three dimensional conformal radiation therapy (3D-CRT) does not necessarily meet all clinical requirements while intensity modulated radiation therapy (IMRT) may take up a lot of labour power and material resources. This study was to explore the feasibility of simplified IMPT(sIMRT) and concurrent chemotherapy for neck and upper thoracic esophageal carcinoma, and to investigate the acute toxicities and short-term efficacy of this treatment modality. sIMRT plans were designed for 30 patients with neck and upper thoracic esophageal carcinoma. Two target volumes were defined: PTV1, which was designed to irradiate to 64 Gy (2.13 Gy x 30 fractions); PTV2, which was given to 54 Gy (1.8 Gy x 30). The sIMRT plan included five equiangular coplanar beams. All patients concurrently received DDP+5-FU regimen with radiotherapy on d1-5 and d29-33. Chemotherapy was repeated for two cycles 28 days after radiotherapy. The treatment was completed for all patients within 6 weeks, and only one patient had Grade 3 acute bronchitis. The complete response (CR) rate was 90.0% (27/30) and the partial response (PR) rate 10.0% (3/30). Overall response was 100% for esophageal lesions and the CR rate 76.5% (13/17). The PR rate was 23.5% (4/17) in lymph node lesions. The major toxicities observed were Grades I-II leukocytopenia. sIMRT can generate desirable dose distribution for neck and upper thoracic esophageal carcinoma, which is similar to sophisticated IMRT but obviously better than 3D-CRT. The short-term efficacy of sIMRT is satisfactory and its acute toxicities are tolerable.

Advances in the technology and improved access to imaging modalities such as Computed Tomography and laparoscopy have changed the contemporary diagnostic and management of acute appendicitis. Complicated appendicitis (phlegmon, abscess and/ or diffuse peritonitis), is now reliably distinguished from uncomplicated cases. Therefore, a new comprehensive grading system for acute appendicitis is necessary. The goal is review and update the laparoscopic grading system of acute appendicitis and to provide a new standardized classification system to allow more uniform patient stratification. During the last World Society of Emergency Surgery Congress in Israel (July, 2015), a panel involving Acute Appendicitis Experts and the author's discussed many current aspects about the acute appendicitis between then, it will be submitted a new comprehensive disease grading system. It was idealized based on three aspect of the disease (clinical and imaging presentation and laparoscopic findings). The new grading system may provide a standardized system to allow more uniform patient stratification for appendicitis research. In addition, may aid in determining optimal management according to grade. Lastly, what we want is to draw a multicenter observational study within the World Society of Emergency Surgery (WSES) based on this design.

The esophagus is physiologically devoid of eosinophils, so their presence would suggest some underlying pathology. The prevalence of eosinophilic esophagitis (EoE) has steadily increased in Western countries. Previous studies have described EoE in association with congenital esophageal atresia (CEA), which is the most common congenital anomaly of the esophagus. However, the association remains unclear. We performed a retrospective histological analysis examining for eosinophil infiltration in the esophagus of patients with CEA following surgical repair or congenital esophageal stenosis (CES) who underwent esophageal biopsy or surgical resection in our hospital between 2005 and 2012. There were 6 patients with CEA following surgical repair or CES who had eosinophil-dominant infiltration in the esophagus. All had associated allergic disorders, including food allergies in 4. Moreover, all except for one fulfilled the histological criteria of EoE. Impairment of eosinophil infiltration and symptomatic improvement were observed in those treated with a proton pump inhibitor (PPI), either alone or in combination with steroids after esophageal dilatation. These findings suggest that CEA repair or CES in conjunction with allergic conditions and coexisting gastroesophageal reflux disease (GERD) may induce greater esophageal eosinophilic inflammation. In addition, esophageal dilatation followed by PPI treatment, alone or with steroids, may be a therapeutic strategy that can provide symptomatic relief by reducing eosinophilic inflammation in esophageal strictures or GERD associated with CEA or CES.

Esophageal motor disorders, often leading to dysphagia and chest pain, continue to pose diagnostic and therapeutic problems. In the past 12 months important new information regarding esophageal motor disorders was published. This information will be reviewed in this paper. A number of studies have addressed the issue of heterogeneity in achalasia, the best defined esophageal motility disorder. The spastic esophageal motility disorders nutcracker esophagus and diffuse esophageal spasm may coexist with gastroesophageal reflux disease, which has consequences for the management of patients with these disorders. The entity labelled ineffective esophageal motility is associated with reflux esophagitis, but also with morbid obesity. For the detection of disordered transit caused by ineffective esophageal motility, application of intraluminal impedance monitoring in conjunction with manometry leads to improved diagnosis. New data on the effect of Nissen fundoplication on esophageal motility were published during the last year. Recent knowledge on the heterogeneity of achalasia and the association of spastic esophageal motor disorders and ineffective motility with reflux disease will help the clinician in the management of patients with these disorders.

A number of congenital and acquired disorders require esophageal tissue replacement. Various surgical techniques, such as gastric and colonic interposition, are standards of treatment, but frequently complicated by stenosis and other problems. Regenerative medicine approaches facilitate the use of biological constructs to replace or regenerate normal tissue function. We review the literature of esophageal tissue engineering, discuss its implications, compare the methodologies that have been employed and suggest possible directions for the future. Medline, Embase, the Cochrane Library, National Research Register and ClinicalTrials.gov databases were searched with the following search terms: stem cell and esophagus, esophageal replacement, esophageal tissue engineering, esophageal substitution. Reference lists of papers identified were also examined and experts in this field contacted for further information. All full-text articles in English of all potentially relevant abstracts were reviewed. Tissue engineering has involved acellular scaffolds that were either transplanted with the aim of being repopulated by host cells or seeded prior to transplantation. When acellular scaffolds were used to replace patch and short tubular defects they allowed epithelial and partial muscular migration whereas when employed for long tubular defects the results were poor leading to an increased rate of stenosis and mortality. Stenting has been shown as an effective means to reduce stenotic changes and promote cell migration, whilst omental wrapping to induce vascularization of the construct has an uncertain benefit. Decellularized matrices have been recently suggested as the optimal choice for scaffolds, but smart polymers that will incorporate signalling to promote cell-scaffold interaction may provide a more reproducible and available solution.

Lichen planus is a chronic inflammatory disease that affects the skin, mucous membranes, nails and scalp. Esophageal lichen planus is a rarely reported manifestation of lichen planus, presenting itself commonly in middle-aged women, with symptoms such as dysphagia. We report a case of esophageal lichen planus in a 54-year-old woman associated with oral, cutaneous and ungual lichen planus. Although lichen planus is a disorder well known by dermatologists, reports of esophageal lichen planus are rare in dermatologic literature. The esophageal lichen planus is little known and underdiagnosed, with a significant delay between the onset of symptoms and diagnosis.

Predictive value of preoperative endoscopic characteristic of esophageal tumor has not been fully evaluated. The aim of this study is to investigate the impact of esophageal luminal stenosis on survival for patients with resectable esophageal squamous cell carcinoma (ESCC). The clinicopathologic characteristics of 623 ESCC patients who underwent curative resection as the primary treatment between January 2005 and April 2009 were retrospectively reviewed. The esophageal luminal stenosis measured by endoscopy was defined as a uniform measurement preoperatively. The impact of esophageal luminal stenosis on patients' overall survival (OS) and relation with other clinicopathological features were assessed. A Cox regression model was used to identify prognostic factors. The results showed that OS significantly decreased in patients with manifest stenotic tumor compared with patients without luminal obstruction (P<0.05). Considerable esophageal luminal stenosis was associated with a higher T stage, longer tumor length, and poorer differentiation (all P<0.05). In multivariate survival analysis, esophageal luminal stenosis remained as an independent prognostic factor for OS (P= 0.036). Esophageal luminal stenosis could have a significant impact on the OS in patients with resected ESCC and may provide additional prognostic value to the current staging system before any cancer-specific treatment.

AIM: To investigate esophageal Helicobacter pylori (H. pylori) colonization on esophageal injury caused by reflux and the related mechanisms. METHODS: An esophagitis model, with acid and bile reflux, was surgically produced in male rats. The rats were randomly divided into either: (1) an esophagogastroduodenal anastomosis (EGDA) group; (2) an EGDA with H. pylori infection group; (3) a pseudo-operation with H. pylori infection group; or (4) a pseudo-operation group. All rats were kept for 36 wk. Based on the location of H. pylori colonization, the EGDA rats with H. pylori infection were subdivided into those with concomitant esophageal H. pylori colonization or those with only gastric H. pylori colonization. The esophageal injuries were evaluated grossly and microscopically. The expressions of CDX2 and MUC2 were determined by real-time polymerase chain reaction (RT-PCR) and immunohistochemistry. Ki-67 antigen expression was determined by immunohistochemistry. The mRNA levels of cyclin D1, c-Myc, Bax and Bcl-2 were determined by RT-PCR. Cell apoptosis was evaluated using the TdT-mediated dUTP nick-end labeling method. RESULTS: Esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) developed in rats that underwent EGDA. When comparing rats with EGDA and concomitant esophageal H. pylori colonization to EGDA-only rats, the severity of injury (87.9 ± 5.2 vs 77.2 ± 8.6, macroscopically, 92.5 ± 8.0 vs 83.8 ± 5.5, microscopically, both P < 0.05) and the incidences of BE (80.0% vs 33.3%, P = 0.055) and EAC (60.0% vs 11.1%, P < 0.05) were increased. These increases were associated with upregulation of CDX2 and MUC2 mRNA (10.1 ± 5.4 vs 3.0 ± 2.9, 8.4 ± 4.6 vs 2.0 ± 3.2, respectively, Ps < 0.01) and protein (8.1 ± 2.3 vs 3.3 ± 3.1, 7.3 ± 4.0 vs 1.8 ± 2.7, respectively, all P < 0.05). The expression of Ki-67 (8.9 ± 0.7 vs 6.0 ± 1.7, P < 0.01) and the presence of apoptotic cells (8.3 ± 1.1 vs 5.3 ± 1.7, P < 0.01) were also increased

It is mainly offered to medically high-risk patients. However, no analysis of risks of botox injections has been performed. To determine the incidence and risk factors of procedure-related complications after esophageal botox injections, we analyzed the records of all patients undergoing botox injection therapy for esophageal motility disorders at four university hospitals in Europe and North America between 2008 and 2014. Complications were assigned grades according to the Clavien-Dindo classification. In 386 patients, 661 botox treatments were performed. Main indications were achalasia (51%) and distal esophageal spasm (DES) (30%). In total, 52 (7.9%) mild complications (Clavien-Dindo grade I) were reported by 48 patients, the majority consisting of chest pain or heartburn (29 procedures) or epigastric pain (5 procedures). No ulceration, perforation, pneumothorax, or abscess were reported. One patient died after developing acute mediastinitis (Clavien-Dindo grade V) following injections in the body of the esophagus. In univariate logistic regression, younger age was associated with an increased risk of complications (OR 1.43, 95%CI 1.03-1.96). Treatment for DES, injections into the esophageal body, more injections per procedure, more previous treatments and larger amount of injected botulinum toxin were no risk factors for complications. Esophageal botox injection seems particularly appropriate for high-risk patients due to low complication rate. However, it should not be considered completely safe, as it is associated with rare side effects that cannot be predicted. © 2016 International Society for Diseases of the Esophagus.

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

Expandable esophageal stents are widely used for the palliation of dysphagia in patients with esophageal cancer and are also beginning to be used in patients with benign esophageal diseases such as refractory strictures and fistulas. There is concern regarding the increased risk of migration of the fully covered Alimaxx metal esophageal stent and experience with this stent in benign esophageal pathology has been reported in only a small series of patients. To evaluate the technical success in placement and removal, efficacy and complications of the Alimaxx esophageal stent for benign esophageal diseases. Our endoscopy database was retrospectively reviewed from 1/2003 to 2/2009 to identify patients with Alimaxx esophageal stent placement for benign diseases. Chart review was performed for age, gender, indication, site of the lesion, success of placement, outcome, and incidence of complications. Twenty-eight stents were successfully placed in 14 patients with benign esophageal diseases (mean: two stents/patient; range 1-7). Indications included esophageal fistula in seven (50%) and benign strictures in 7/14 (50%). Dysphagia improved in all patients while the fistula resolved in 6/7 (85.8%) patients. Complications related to stents included pain (2/28, 7%), stent related gastric ulcer (1/28, 4%), nausea and vomiting (3/21, 11%) and stent migration (11/28, 39%). All migrated stents were successfully endoscopically retrieved. The fully covered and removable Alimaxx stent is effective in the endoscopic management of benign esophageal strictures or fistulas, despite its relatively high rate of migration. Stent migration was successfully managed endoscopically without complications.

Abstract Esophageal fistula is a critical adverse event in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer. However, risk factors associated with esophageal fistula formation in patients receiving CRT have not yet been elucidated. We retrospectively analyzed data obtained from 140 patients who were enrolled in a phase II/III trial comparing low-dose cisplatin with standard-dose cisplatin administered in combination with 5-flurouracil and concomitant radiotherapy. Inclusion criteria were performance status (PS) 0 to 2 and histologically proven thoracic esophageal cancer clinically diagnosed as T4 and/or unresectable lymph node metastasis for which definitive CRT was applicable. Risk factors for esophageal fistula were examined with univariate analysis using Fisher exact test and multivariate analysis using logistic regression models. Esophageal fistula was observed in 31 patients (22%). Of these, 6 patients developed fistula during CRT. Median time interval between the date of CRT initiation and that of fistula diagnosis was 100 days (inter quartile range, 45–171). Esophageal stenosis was the only significant risk factor for esophageal fistula formation both in univariate (P = 0.026) and in multivariate analyses (odds ratio, 2.59; 95% confidence interval, 1.13–5.92, P = 0.025). Other clinicopathological factors, namely treatment arm, age, sex, PS, primary tumor location, T stage, lymph node invasion to adjacent organs, blood cell count, albumin level, and body mass index, were not risk factors fistula formation. Esophageal stenosis was a significant risk factor for esophageal fistula formation in patients treated with CRT for unresectable locally advanced thoracic esophageal squamous cell carcinoma.

The transient receptor potential vanilloid 1 has been implicated as a target mediator for heartburn perception and modulation of esophageal secondary peristalsis. Our aim was to determine the effect of repeated esophageal infusion of capsaicin-contained red pepper sauce on heartburn perception and secondary peristalsis in healthy adults. Secondary peristalsis was performed with mid-esophageal injections of air in 15 healthy adults. Two separate protocols including esophageal infusion with saline and capsaicin-contained red pepper sauce and 2 consecutive sessions of capsaicin-contained red pepper sauce were randomly performed. After repeated infusion of capsaicin-contained red pepper sauce, the threshold volume to activate secondary peristalsis was significantly increased during slow (p < 0.001) and rapid air injections (p = 0.004). Acute infusion of capsaicin-contained red pepper sauce enhanced heartburn perception (p < 0.001), but the intensity of heartburn perception was significantly reduced after repeated capsaicin-contained red pepper sauce infusion (p = 0.007). Acute infusion of capsaicin-contained red pepper sauce significantly increased pressure wave amplitudes of distal esophagus during slow (p = 0.003) and rapid air injections (p = 0.01), but repeated infusion of capsaicin-contained red pepper sauce significantly decreased pressure wave amplitude of distal esophagus during slow (p = 0.0005) and rapid air injections (p = 0.003). Repeated esophageal infusion of capsaicin appears to attenuate heartburn perception and inhibit distension-induced secondary peristalsis in healthy adults. These results suggest capsaicin-sensitive afferents in modulating sensorimotor function of secondary peristalsis in human esophagus. © 2014 John Wiley & Sons Ltd.

Methods: As part of an AOSpine series on rare complications, a retrospective cohort study was conducted among 21 high-volume surgical centers to identify esophageal perforations following anterior cervical spine surgery. Staff at each center abstracted data from patients’ charts and created case report forms for each event identified. Case report forms were then sent to the AOSpine North America Clinical Research Network Methodological Core for data processing and analysis. Results: The records of 9591 patients who underwent anterior cervical spine surgery were reviewed. Two (0.02%) were found to have esophageal perforations following anterior cervical spine surgery. Both cases were detected and treated in the acute postoperative period. One patient was successfully treated with primary repair and debridement. One patient underwent multiple debridement attempts and expired. Conclusions: Esophageal perforation following anterior cervical spine surgery is a relatively rare occurrence. Prompt recognition and treatment of these injuries is critical to minimizing morbidity and mortality. PMID:28451488

Background Predictive value of preoperative endoscopic characteristic of esophageal tumor has not been fully evaluated. The aim of this study is to investigate the impact of esophageal luminal stenosis on survival for patients with resectable esophageal squamous cell carcinoma (ESCC). Methods The clinicopathologic characteristics of 623 ESCC patients who underwent curative resection as the primary treatment between January 2005 and April 2009 were retrospectively reviewed. The esophageal luminal stenosis measured by endoscopy was defined as a uniform measurement preoperatively. The impact of esophageal luminal stenosis on patients’ overall survival (OS) and relation with other clinicopathological features were assessed. A Cox regression model was used to identify prognostic factors. Results The results showed that OS significantly decreased in patients with manifest stenotic tumor compared with patients without luminal obstruction (P<0.05). Considerable esophageal luminal stenosis was associated with a higher T stage, longer tumor length, and poorer differentiation (all P<0.05). In multivariate survival analysis, esophageal luminal stenosis remained as an independent prognostic factor for OS (P= 0.036). Conclusions Esophageal luminal stenosis could have a significant impact on the OS in patients with resected ESCC and may provide additional prognostic value to the current staging system before any cancer-specific treatment.

Esophageal cancer has a poor prognosis and high mortality rate, with an estimated 16,910 new cases and 15,910 deaths projected in 2016 in the United States. Squamous cell carcinoma and adenocarcinoma account for more than 95% of esophageal cancers. Squamous cell carcinoma is more common in nonindustrialized countries, and important risk factors include smoking, alcohol use, and achalasia. Adenocarcinoma is the predominant esophageal cancer in developed nations, and important risk factors include chronic gastroesophageal reflux disease, obesity, and smoking. Dysphagia alone or with unintentional weight loss is the most common presenting symptom, although esophageal cancer is often asymptomatic in early stages. Physicians should have a low threshold for evaluation with endoscopy if any symptoms are present. If cancer is confirmed, integrated positron emission tomography and computed tomography should be used for initial staging. If no distant metastases are found, endoscopic ultrasonography should be performed to determine tumor depth and evaluate for nodal involvement. Localized tumors can be treated with endoscopic mucosal resection, whereas regional tumors are treated with esophagectomy, neoadjuvant chemotherapy, chemoradiotherapy, or a combination of modalities. Nonresectable tumors or tumors with distant metastases are treated with palliative interventions. Specific prevention strategies have not been proven, and there are no recommendations for esophageal cancer screening.

A 68-year-old Japanese man had been diagnosed with esophageal achalasia and underwent surgical treatment 33 years earlier. He was examined at our hospital for annual routine checkup in which upper gastrointestinal endoscopy showed a "0-IIb+IIa" lesion in the middle esophagus. Iodine staining revealed multiple irregularly shaped iodine-unstained areas, the diagnosis of which was esophageal carcinoma. Thoracoscopic subtotal esophagectomy was performed. Esophageal carcinoma may occur many years after surgery for esophageal achalasia, even if the passage symptoms have improved. So, long-term periodic follow-up is necessary for detection of carcinoma at an earlier stage.

Esophageal fistula is a serious and common complication of radiotherapy for esophageal cancer. Therefore, early diagnosis and treatment is necessary. Because of side effect of barium esophagography, it cannot be used to screening esophageal fistula during radiotherapy. Meglumine diatrizoate is an ionic contrast agent, its adverse reactions were rarely seen when it was used in the body cavity. The purpose of this trial is identified the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy. This trial was a prospective, multicenter, diagnostic clinical trial. A total of 105 patients with esophageal cancer will swallowed meglumine diatrizoate and underwent a radiographic examination weekly during radiotherapy, medical personnel observed the esophageal lesions to determine whether an esophageal fistula formed. If an esophageal fistula was observed, esophagofiberoscopy and/or computer tomography was used to further confirm the diagnosis. And the sensitivity and specificity of meglumine diatrizoate should be calculated for screening esophageal fistula during radiotherapy. To our knowledge, this study protocol is the first to identify the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy. If oral meglumine diatrizoate can be used to screening esophageal fistula, more patients will benefit from early detection and treatment.

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

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

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.

Purpose: The aim of this study was to quantify the dose delivered to the pharyngo-esophageal axis using different intensity-modulated radiation therapy (IMRT) techniques for treatment of nasopharyngeal carcinoma and to correlate this with acute swallowing toxicity. Methods and Materials: The study population consisted of 28 patients treated with IMRT between February 2002 and August 2005: 20 with whole field IMRT (WF-IMRT) and 8 with IMRT fields junctioned with an anterior neck field with central shielding (j-IMRT). Dose to the pharyngo-esophageal axis was measured using dose-volume histograms. Acute swallowing toxicity was assessed by review of dysphagia grade during treatment and enteralmore » feeding requirements. Results: The mean pharyngo-esophageal dose was 55.2 Gy in the WF-IMRT group and 27.2 Gy in the j-IMRT group, p < 0.001. Ninety-five percent (19/20) of the WF-IMRT group developed Grade 3 dysphagia compared with 62.5% (5/8) of the j-IMRT group, p = 0.06. Feeding tube duration was a median of 38 days for the WF-IMRT group compared with 6 days for the j-IMRT group, p = 0.04. Conclusions: Clinical vigilance must be maintained when introducing new technology to ensure that unanticipated adverse effects do not result. Although newer planning systems can reduce the dose to the pharyngo-esophageal axis with WF-IMRT, the j-IMRT technique is preferred at least in patients with no gross disease in the lower neck.« less

To investigate the effects of peroral endoscopic myotomy(POEM) on esophageal dynamics in patients with esophageal achalasia. From September 2011 to November 2011, 20 cases with esophageal achalasia received POEM at the Endoscopic Center in the Zhongshan Hospital of Fudan University. Pre-operation esophageal dynamics of all the patients were evaluated by high resolution manometry(HRM) system and 3 days after operation the test was repeated. Lower esophagus sphincter resting pressure(LESP), 4-second integrated relaxation pressure(4sIRP), lower esophagus sphincter relax rate(LESRR), lower esophagus sphincter length(LESL), and esophageal manometry were analyzed. After POEM, LESP decreased from(29.1±17.0) mm Hg to(14.6±4.9) mm Hg, and decrease rate was 49.8%(P<0.01). However, the decreases in LESRR and LESL were not statistically significant(P>0.05). Esophageal peristaltic contraction was absent in all the 20 patients preoperatively. After POEM, changes in the esophageal contraction were seen in 7 patients, and peristalsis was noticed but was below normal level. There were no significant changes in peristalsis in the remaining 13 patients. POEM can significantly reduce LESP and 4sIRP in patients with achalasia, but can not affect the contraction of the esophagus.

High-resolution manometry (HRM) has resulted in new revelations regarding the pathophysiology of gastro-esophageal reflux disease (GERD). The impact of new HRM motor paradigms on reflux burden needs further definition, leading to a modern approach to motor testing in GERD. Focused literature searches were conducted, evaluating pathophysiology of GERD with emphasis on HRM. The results were discussed with an international group of experts to develop a consensus on the role of HRM in GERD. A proposed classification system for esophageal motor abnormalities associated with GERD was generated. Physiologic gastro-esophageal reflux is inherent in all humans, resulting from transient lower esophageal sphincter (LES) relaxations that allow venting of gastric air in the form of a belch. In pathological gastro-esophageal reflux, transient LES relaxations are accompanied by reflux of gastric contents. Structural disruption of the esophagogastric junction (EGJ) barrier, and incomplete clearance of the refluxate can contribute to abnormally high esophageal reflux burden that defines GERD. Esophageal HRM localizes the LES for pH and pH-impedance probe placement, and assesses esophageal body peristaltic performance prior to invasive antireflux therapies and antireflux surgery. Furthermore, HRM can assess EGJ and esophageal body mechanisms contributing to reflux, and exclude conditions that mimic GERD. Structural and motor EGJ and esophageal processes contribute to the pathophysiology of GERD. A classification scheme is proposed incorporating EGJ and esophageal motor findings, and contraction reserve on provocative tests during HRM. © 2017 John Wiley & Sons Ltd.

The purpose of this study is to characterize the esophageal motor and lower esophageal sphincter (LES) abnormalities associated with epiphrenic esophageal diverticula and analyze outcomes for laparoscopic esophageal diverticulectomy, myotomy, and partial fundoplication. The endoscopic, radiographic, manometric, and perioperative records for patients undergoing laparoscopic esophageal diverticulectomy, anterior esophageal myotomy, and partial fundoplication from 8/99 until 9/06 were reviewed from an Institutional Review Board (IRB)-approved outcomes database. Data are given as mean +/- standard deviation (SD). An esophageal body motor disorder and/or LES abnormalities were present in 11 patients with epiphrenic diverticula; three patients were characterized as achalasia, one had vigorous achalasia, two had diffuse esophageal spasm, and five had a nonspecific motor disorder. Presenting symptoms included dysphagia (13/13), regurgitation (7/13), and chest pain (4/13). Three patients had previous Botox injections and three patients had esophageal dilatations. Laparoscopic epiphrenic diverticulectomy with an anterior esophageal myotomy was completed in 13 patients (M:F; 3:10) with a mean age of 67.6 +/- 4.2 years, body mass index (BMI) of 28.1 +/- 1.9 kg/m2 and American Society of Anesthesiologists (ASA) 2.2 +/- 0.1. Partial fundoplication was performed in 12/13 patients (Dor, n = 2; Toupet, n = 10). Four patients had a type I and one patient had a type III hiatal hernia requiring repair. Mean operative time was 210 +/- 15.1 min and mean length of stay (LOS) was 2.8 +/- 0.4 days.

Primary Esophageal Motility Disorders: Beyond Achalasia.

PubMed

Schlottmann, Francisco; Patti, Marco G

2017-06-30

The best-defined primary esophageal motor disorder is achalasia. However, symptoms such as dysphagia, regurgitation and chest pain can be caused by other esophageal motility disorders. The Chicago classification introduced new manometric parameters and better defined esophageal motility disorders. Motility disorders beyond achalasia with the current classification are: esophagogastric junction outflow obstruction, major disorders of peristalsis (distal esophageal spasm, hypercontractile esophagus, absent contractility) and minor disorders of peristalsis (ineffective esophageal motility, fragmented peristalsis). The aim of this study was to review the current diagnosis and management of esophageal motility disorders other than achalasia.

The present study was carried out to evaluate the effect of dried mature unripe Morinda citrifolia L. (Rubiaceae) fruit, commonly known as "Noni", in an aqueous extract preparation (AFE) as used in Thai traditional medicine and its biomarker scopoletin on gastro-esophageal inflammatory models that are related to the claimed pharmacological properties of AFE and/or resembled the human esophagitis or gastric ulcer. The powder of dried mature unripe Noni fruit was boiled in water until it became a sticky paste and was then dried into a powder by lyophilization. The pharmacological activity of AFE and pure scopoletin at the same equivalent dose present in AFE was investigated in rat on gastro-esophageal inflammatory models (acid reflux esophagitis, acute gastritis induced by ethanol and serotonin, and chronic gastric ulcer induced by acetic acid); gastric biochemical parameters and gastrointestinal motility. AFE (0.63-2.50 g/kg) significantly prevented the formation of acid reflux esophagitis, reduced the formation of ethanol-induced acute gastric lesions, suppressed the development of gastric lesions in response to serotonin, and accelerated the healing of acetic acid-induced chronic gastric ulcer in rats with equal potency to those obtained by standard antisecretory agents (ranitidine and lansoprazole). AFE also significantly inhibited gastric acid secretion and pepsin activity in pylorus ligated rats. Additionally, AFE strongly increased the gastrointestinal transit of charcoal meal with a higher potency than cisapride. Pure scopoletin, when compared at the same equivalent dose containing in AFE, possessed similar antiulcer and antisecretory properties to that of AFE although it exerted a less prokinetic activity than AFE. The findings indicated that AFE as well as its biomarker: scopoletin may be beneficial as a potential preventive and therapeutic agent for gastro-esophageal inflammatory diseases, mainly through its antisecretory and prokinetic activities

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.

The association of esophageal motility and gastroesophageal reflux symptoms with respiratory symptoms is not well established in patients with chronic obstructive pulmonary disease (COPD). The aim of this work is to study the abnormalities of esophageal function in COPD patients and study its relation to smoking index, body mass index and indices of hyperinflation. This study included 40 male COPD patients and 10 healthy controls. The patients and controls were subjected to spirometry, body plethysmography, esophageal manometry and 24hr pH-metry. Upper gastrointestinal symptoms were found in 55% of patients, hypotensive upper esophageal sphincter pressure in 65% of patients and hypotensive lower esophageal sphincter pressure in 52.5% of patients. Pathological acid reflux was found in 35% of patients. The severity of GERD increased with increased age, smoking index and body mass index, p<0.005. There was negative correlation between LESP and UESP compared with indices of hyperinflation, p<0.001. There was high prevalence of esophageal motility disorders in COPD patients, LESP and UESP were significantly negatively correlated to indices of hyperinflation. There was a high prevalence of GERD in COPD patents especially elderly, severe stage of COPD, high smoking index and high body mass index (BMI).

Indwelling esophageal balloon catheter for benign esophageal stenosis in infants and children.

Balloon dilatation of benign esophageal strictures is an established mode of therapy in adults and children. There remains a group of patients with refractory stenosis despite dilatation at regular intervals. An indwelling balloon catheter may offer an alternative. This is a retrospective study of 19 children who underwent esophagoscopy between 2004 and 2012 with placement of an indwelling balloon catheter for refractory esophageal stenosis. Total number of endoscopies, number of endoscopies with indwelling balloon catheter, as well as complications, reoperations, and mortality due to use of the balloon catheter were studied. Patient age ranged from 4 weeks to 15 years. The indwelling balloon catheter was used to treat refractory stenosis after corrective surgery of long gap esophageal atresia (n = 5), esophageal atresia with distal fistula (n = 2), refractory esophageal stenosis due to caustic esophageal burns (n = 7), reflux (n = 2), and stenosis of unknown cause (n = 3). With the indwelling balloon catheter in place, the mean number of endoscopies equalled four. Complications were restenosis after a symptom-free period for which a new indwelling balloon catheter was necessary (n = 3). Two others needed two to five additional dilations: balloon leakage requiring replacement (n = 7 in 5 patients), sputum retention (n = 1), and dislodgement (n = 5 in 4 patients). More importantly, there was no mortality or the need for any patient to undergo a surgical resection. The indwelling balloon catheter is safe to use and can be used by parents at home. More importantly it obviates the need for rethoracotomy/-scopy or esophageal replacement.

Abstract Upper gastrointestinal (GI) symptoms are common in both HIV and non-HIV-infected patients, but the difference of GI symptom severity between 2 groups remains unknown. Candida esophagitis and erosive esophagitis, 2 major types of esophagitis, are seen in both HIV and non-HIV-infected patients, but differences in GI symptoms that are predictive of esophagitis between 2 groups remain unknown. We aimed to determine whether GI symptoms differ between HIV-infected and non-HIV-infected patients, and identify specific symptoms of candida esophagitis and erosive esophagitis between 2 groups. We prospectively enrolled 6011 patients (HIV, 430; non-HIV, 5581) who underwent endoscopy and completed questionnaires. Nine upper GI symptoms (epigastric pain, heartburn, acid regurgitation, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia) were evaluated using a 7-point Likert scale. Associations between esophagitis and symptoms were analyzed by the multivariate logistic regression model adjusted for age, sex, and proton pump inhibitors. Endoscopy revealed GI-organic diseases in 33.4% (2010/6.011) of patients. The prevalence of candida esophagitis and erosive esophagitis was 11.2% and 12.1% in HIV-infected patients, respectively, whereas it was 2.9% and 10.7 % in non-HIV-infected patients, respectively. After excluding GI-organic diseases, HIV-infected patients had significantly (P < 0.05) higher symptom scores for heartburn, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia than non-HIV-infected patients. In HIV-infected patients, any symptom was not significantly associated with CD4 cell count. In multivariate analysis, none of the 9 GI symptoms were associated with candida esophagitis in HIV-infected patients, whereas dysphagia and odynophagia were independently (P < 0.05) associated with candida esophagitis in non-HIV-infected patients. However, heartburn and acid regurgitation were independently (P < 0

Esophageal duplication cysts are rare congenital abnormalities of the foregut and may be associated with other conditions. Association of esophageal duplication with Gastro-Esophageal Reflux Disease (GERD) has not been reported in children. We are reporting a case of a 16 months baby who had antenatal diagnosis of diaphragmatic hernia. Postnatal CTchest, however, suggested a distal esophageal duplication cyst and a contrast esophagogram showed grade-IV GER. A thoracoscopy in another hospital excluded esophageal duplication at that time. Later, he presented with hematemesis in our department and was re-evaluated. Repeat CTconfirmed a persistent 2.5 x 1.3 cm cyst in distal esophagus. Upper GI endoscopy suggested grade-II esophagitis with a wide patent gastro-esophageal junction. The child was treated with left thoracotomy, excision of the duplication cyst and thoracic fundoplication. He had an uneventful post-operative recovery and is doing well at 6 months follow-up.

We herein report three cases of the malignant esophageal stenosis successfully treated with the Niti-S™ esophageal stent. CASE 1: The hilar lung cancer and its mediastinal lymph node metastasis pressed the esophagus extramurally and caused the marked stenosis. CASE 2: A metastatic lymph node along the left laryngeal nerve caused the stenosis of the trachea. A primary esophageal lesion located at the middle thoracic esophagus also caused the marked stenosis. At first, tracheal stent was placed because of dyspnea, and two weeks later, we placed an esophageal stent. Case 3: Esophageal cancer at lower thoracic esophagus after definitive radiation therapy caused the marked stenosis. Because of the stenosis of esophago-gastric junction( EGJ), we used an esophageal stent with a long cover in order to prevent a reflux into the esophagus. This new Niti-STM esophageal stent was easy to place at the stenosis without difficulty using a conventional device. The symptom was improved immediately for each case. We hope this new device will be used widely.

Esophageal manometry in gastroesophageal reflux disease.

High-resolution manometry (HRM) allows nuanced evaluation of esophageal motor function, and more accurate evaluation of lower esophageal sphincter (LES) function, in comparison with conventional manometry. Pathophysiologic correlates of gastroesophageal reflux disease (GERD) and esophageal peristaltic performance are well addressed by this technique. HRM may alter the surgical decision by assessment of esophageal peristaltic function and exclusion of esophageal outflow obstruction before antireflux surgery. Provocative testing during HRM may assess esophageal smooth muscle peristaltic reserve and help predict the likelihood of transit symptoms following antireflux surgery. HRM represents a continuously evolving new technology that compliments the evaluation and management of GERD. Copyright © 2014 Elsevier Inc. All rights reserved.

Recovery of normal esophageal function in a kitten with diffuse megaesophagus and an occult lower esophageal stricture.

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. © ISFM and AAFP 2014.

We herein report our technique for laparoscopic esophageal myotomy combined with Collis gastroplasty and Nissen fundoplication for severe esophageal stenosis. Our patient had experienced vomiting since childhood, and his dysphagia had gradually worsened. He was referred to our department for surgery because of resistance to pneumatic dilation. He was diagnosed with a short esophagus based on the findings of a preoperative upper gastrointestinal series and GI endoscopy. After exposing the abdominal esophagus, esophageal myotomy around the esophago-gastric junction (EGJ) was undertaken to introduce an esophageal bougie into the stomach. Then, stapled wedge gastroplasty was performed, and a short and loose Nissen fundoplication was performed. In addition, the bulging mucosa after myotomy was patched using the Dor method. The patient's postoperative course was uneventful. Most patients with esophageal stricture require subtotal esophagectomy. Laparoscopic surgery for patients with benign esophageal stricture refractory to repeated pneumatic dilation is challenging. However, our current procedure might abrogate the need for invasive esophagectomy for the surgical management of severe esophageal stenosis.

Objectives Dysphagia is common in total laryngectomees, with some symptoms suggesting esophageal dysmotility. Tracheoesophageal (TE) phonation requires effective esophagopharyngeal air passage. Hence, esophageal dysmotility may affect deglutition or TE phonation. This study aimed to determine (1) the characteristics of esophageal dysmotility in laryngectomees, (2) whether clinical history is sensitive in detecting esophageal dysmotility, and (3) the relationship between esophageal dysmotility and TE prosthesis dysfunction. Study Design Multidisciplinary cross-sectional study. Setting Tertiary academic hospital. Subjects and Methods For 31 participants undergone total laryngectomy 1 to 12 years prior, clinical histories were taken by a gastroenterologist and a speech pathologist experienced in managing dysphagia. Esophageal high-resolution manometry was performed and analyzed using Chicago Classification v3.0. Results Interpretable manometric studies were obtained in 23 (1 normal manometry). Esophageal dysmotility patterns included achalasia, esophagogastric junction outflow obstruction, diffuse esophageal spasm, and other major (30%) and minor (50%) peristaltic disorders. The sensitivity of predicting any esophageal dysmotility was 28%, but it is noteworthy that patients with achalasia and diffuse esophageal spasm (DES) were predicted. Two of 4 participants with TE puncture leakage had poor esophageal clearance. Of 20 TE speakers, 12 had voice problems, no correlation between poor voice, and any dysmotility pattern. Conclusions Peristaltic and lower esophageal sphincter dysfunction are common in laryngectomees. Clinical history, while not predictive of minor motor abnormalities, predicted correctly cases with treatable spastic motor disorders. Dysmotility was not associated with poor phonation, although TE puncture leakage might be linked to poor esophageal clearance. Esophageal dysmotility should be considered in the laryngectomees with persisting dysphagia or

The aim of this article is to highlight literature published during the last year in the context of previous knowledge. A number of novel techniques - high-resolution manometry, esophageal electrical impedance and intra-luminal ultrasound imaging - have improved our understanding of esophageal function in health and disease. Several studies address the function of longitudinal muscle layer of the esophagus in normal subjects and patients with motor disorders of the esophagus. Esophageal electrical impedance recordings reveal abnormal transit in patients with diffuse esophageal spasm, achalasia and patients with normal manometry. Loss of the mammalian Sprouty2 gene leads to enteric neuronal hyperplasia and esophageal achalasia. Several studies showed excellent long-term results of medical and surgical treatment of achalasia of the esophagus. For the first time, mechanisms of gastroesophageal reflux in critically ill mechanically ventilated patients are reported. Novel pharmacologic strategies in the treatment of reflux disease are highlighted. Several novel techniques, perfected during recent years, have improved our understanding of esophageal function and dysfunction. A number of important observations, reviewed here, provide important insight into the pathogenesis of esophageal motor disorders and treatment of gastroesophageal reflux disease.

Intact esophageal mucosal integrity is essential to prevent symptoms during gastroesophageal reflux events. Approximately 70% of patients with heartburn have macroscopically normal esophageal mucosa. In patients with heartburn, persistent functional impairment of esophageal mucosal barrier integrity may underlie remaining symptoms. Topical protection of a functionally vulnerable mucosa may be an attractive therapeutic strategy. We aimed to evaluate esophageal mucosal functional integrity in patients with heartburn without esophagitis, and test the feasibility of an alginate-based topical mucosal protection. Three distal esophageal biopsies were obtained from 22 patients with heartburn symptoms, and 22 control subjects. In mini-Ussing chambers, the change in transepithelial electrical resistance (TER) of biopsies when exposed to neutral, weakly acidic, and acidic solutions was measured. The experiment was repeated in a further 10 patients after pretreatment of biopsies with sodium alginate, viscous control, or liquid control "protectant" solutions. Biopsy exposure to neutral solution caused no change in TER. Exposure to weakly acidic and acidic solutions caused a greater reduction in TER in patients than in controls (weakly acid -7.2% (95% confidence interval (CI) -9.9 to -4.5) vs. 3.2% (-2.2 to 8.6), P<0.05; acidic -22.8% (-31.4 to 14.1) vs. -9.4% (-17.2 to -1.6), P<0.01). Topical pretreatment with alginate but not with control solutions prevented the acid-induced decrease in TER (-1% (-5.9 to 3.9) vs. -13.5 (-24.1 to -3.0) vs. -13.2 (-21.7 to -4.8), P<0.05). Esophageal mucosa in patients with heartburn without esophagitis shows distinct vulnerability to acid and weakly acidic exposures. Experiments in vitro suggest that such vulnerable mucosa may be protected by application of an alginate-containing topical solution.

We undertook the first case control study of histologically confirmed esophageal candidiasis (EC). A computer search from July 2012 through February 2015 identified 1,011 esophageal specimens, including 40 cases of EC and 20 controls. The EC incidence was 5.2%; it was associated with immunosuppression and endoscopic white plaques and breaks. Smoking was a predisposing factor, and alcohol was protective. EC had no unique symptoms, and 54% of endoscopic reports did not suspect EC. Important histologic clues included superficial and detached fragments of desquamated and hyper-pink parakeratosis, acute inflammation, intraepithelial lymphocytosis, dead keratinocytes, and bacterial overgrowth. Thirty percent had no neutrophilic infiltrate. Pseudohyphae were seen on H&E in 92.5% (n = 37/40). "Upfront" periodic acid-Schiff with diastase (PAS/D) on all esophageal specimens would have generated $68,333.49 in patient charges. Our targeted PAS/D strategy resulted in $13,044.87 in patient charges (cost saving = 80.9%, $55,288.62). We describe the typical morphology of EC and recommend limiting PAS/D to cases where the organisms are not readily identifiable on H&E and with at least one of the following: (1) ulcer, (2) suspicious morphology, and/or (3) clinical impression of EC. © American Society for Clinical Pathology, 2017.

Functional Esophageal Disorders.

PubMed

Aziz, Qasim; Fass, Ronnie; Gyawali, C Prakash; Miwa, Hiroto; Pandolfino, John E; Zerbib, Frank

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.

We aimed to determine the incidence of esophageal strictures in corrosive ingestions and potential predictors of severe injury. This was a retrospective cohort study of corrosive ingestions from a toxicology unit (1987-2013) with telephone follow-up at least 1 y post-ingestion. Clinical data and investigations were obtained from a toxicology admission database. The primary outcome was esophageal stricture. Other outcomes included in-hospital mortality, endoscopy grade and early complications. There were 89 corrosive ingestions; median age, 31 y [1-87 y; 46 females], including 13 strong alkalis (pH>12), 8 strong acids (pH<2), 29 domestic bleaches, 30 other domestic products, 6 non-domestic products and three unknown. Three patients died in hospital within 24 h (phenol, sodium azide, HCl). Two developed strictures (both strong alkalis): one had complete esophageal destruction; another developed a stricture after 25 d (inpatient grade 2A endoscopy). 24 patients were asymptomatic and discharged without complication. 65 patients were symptomatic (4 catastrophic injuries). 61 reported sore mouth/throat (50), abdominal pain (21), chest pain (17), dysphagia (13); 28 had an abnormal oropharyngeal examination. 25/61 symptomatic patients underwent inpatient endoscopy: normal (3), grade 1 (5), grade 2 (15) and grade 3 (2). Of 88 patients, 12 died (3 inpatients, 9 unrelated), 28 couldn't be contacted and 48 were contacted after 1.7-24 y, including two with strictures. Five couldn't be interviewed (normal endoscopy (1), no dysphagia (3) and stroke (1). 4/41 interviewed reported dysphagia but no objective evidence of stricture. All inpatient deaths and severe complications were apparent within hours of ingestion, and occurred with highly corrosive substances. One delayed stricture occurred, not predicted by inpatient endoscopy. Copyright © 2016 Elsevier Inc. All rights reserved.

Esophageal symptoms are common, and can arise from mucosal, motor, functional, and neoplastic processes, among others. Judicious use of diagnostic testing can help define the etiology of symptoms and can direct management. Endoscopy, esophageal high-resolution manometry (HRM), ambulatory pH or pH-impedance manometry, and barium radiography are commonly used for esophageal function testing; functional lumen imaging probe is an emerging option. Recent consensus guidelines have provided direction in using test findings toward defining mechanisms of esophageal symptoms. The Chicago Classification describes hierarchical steps in diagnosing esophageal motility disorders. The Lyon Consensus characterizes conclusive evidence on esophageal testing for a diagnosis of gastroesophageal reflux disease (GERD), and establishes a motor classification of GERD. Taking these recent advances into consideration, our discussion focuses primarily on the indications, technique, equipment, and interpretation of esophageal HRM and ambulatory reflux monitoring in the evaluation of esophageal symptoms, and describes indications for alternative esophageal tests. © 2018 New York Academy of Sciences.

CASE DESCRIPTION A 10-year-old spayed female Rottweiler was referred for evaluation because of a 2-month history of regurgitation and weight loss, despite no apparent change in appetite. The dog had received antiemetic and antacid treatment, without improvement. CLINICAL FINDINGS Physical examination revealed a low body condition score (2/5), but other findings were unremarkable. Diffuse, global esophageal dilatation was noted on plain thoracic radiographs, and normal motility was confirmed through videofluoroscopic evaluation of swallowing. Transhepatic ultrasonographic and CT examination revealed a circumferential, intraparietal lesion in the distal portion of the esophagus causing distal esophageal or cardial subobstruction and no metastases. Incisional biopsy of the lesion was performed, and findings of histologic examination supported a diagnosis of esophageal leiomyoma. TREATMENT AND OUTCOME In view of numerous possible complications associated with esophageal surgery, the decision was made to palliatively treat the dog by transcardial placement of a self-expanding, covered, nitinol esophageal stent under endoscopic guidance. Two weeks after stent placement, radiography revealed complete migration of the stent into the gastric lumen. Gastrotomy was performed, and the stent was replaced and fixed in place. Twenty-four months after initial stent placement, the dog had a healthy body condition and remained free of previous clinical signs. CLINICAL RELEVANCE Diffuse benign muscular neoplasia should be considered as a differential diagnosis for acquired esophageal dilatation in adult and elderly dogs. In the dog of this report, transcardial stent placement resulted in resolution of the clinical signs, with no apparent adverse effect on digestive function. The described procedure could be beneficial for nonsurgical treatment of benign esophageal tumors in dogs.

Crural diaphragm inhibition during esophageal distension correlates with contraction of the esophageal longitudinal muscle in cats.

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.

Esophageal motor function is highly coordinated between central and enteric nervous systems and the esophageal musculature, which consists of proximal skeletal and distal smooth muscle in three functional regions, the upper and lower esophageal sphincters, and the esophageal body. While upper endoscopy is useful in evaluating for structural disorders of the esophagus, barium esophagography, radionuclide transit studies, and esophageal intraluminal impedance evaluate esophageal transit and partially assess motor function. However, esophageal manometry is the test of choice for the evaluation of esophageal motor function. In recent years, high-resolution manometry (HRM) has streamlined the process of acquisition and display of esophageal pressure data, while uncovering hitherto unrecognized esophageal physiologic mechanisms and pathophysiologic patterns. New algorithms have been devised for analysis and reporting of esophageal pressure topography from HRM. The clinical value of HRM extends to the pediatric population, and complements preoperative evaluation prior to foregut surgery. Provocative maneuvers during HRM may add to the assessment of esophageal motor function. The addition of impedance to HRM provides bolus transit data, but impact on clinical management remains unclear. Emerging techniques such as 3-D HRM and impedance planimetry show promise in the assessment of esophageal sphincter function and esophageal biomechanics. © 2013 Blackwell Publishing Ltd.

The Utility of Proton Beam Therapy with Concurrent Chemotherapy for the Treatment of Esophageal Cancers

Lin, Steven H.

2011-01-01

The standard of care for the management of locally advanced esophageal cancers in the United States is chemotherapy combined with radiation, either definitively, or for those who could tolerate surgery, preoperatively before esophagectomy. Although the appropriate radiation dose remains somewhat controversial, the quality of the radiation delivery is critical for the treatment of esophageal cancer since the esophagus is positioned close to vital structures, such as the heart and lung. The volume and relative doses to these normal tissues affect acute and late term complications. Advances in radiation delivery from 2D to 3D conformal radiation therapy, to Intensity Modulated Radiation Therapy (IMRT) or charged particle therapy (carbon ion or proton beam therapy (PBT)), allow incremental improvements in the therapeutic ratio. This could have implications in non-cancer related morbidity for long term survivors. This article reviews the evolution in radiation technologies and the use of PBT with chemotherapy in the management of esophageal cancer. PMID:24213126

OBJECTIVE The purpose of this article is to describe the imaging and clinicopathologic characteristics of esophageal gastrointestinal stromal tumors (GISTs) and to emphasize the features that differentiate esophageal GISTs from esophageal leiomyomas. MATERIALS AND METHODS A pathology database search identified all surgically resected or biopsied esophageal GISTs, esophageal leiomyomas, and esophageal leiomyosarcomas from 1994 to 2012. Esophageal GISTs were included only if imaging studies (including CT, fluoroscopic, or 18F-FDG PET/CT scans) and clinical data were available. RESULTS Nineteen esophageal mesenchymal tumors were identified, including eight esophageal GISTs (42%), 10 esophageal leiomyomas (53%), and one esophageal leiomyosarcoma (5%). Four patients (50%) with esophageal GIST had symptoms, including dysphagia in three (38%), cough in one (13%), and chest pain in one (13%). One esophageal GIST appeared on barium study as a smooth submucosal mass. All esophageal GISTs appeared on CT as well-marginated predominantly distal lesions, isoattenuating to muscle, that moderately enhanced after IV contrast agent administration. Compared with esophageal leiomyomas, esophageal GISTs tended to be more distal, larger, and more heterogeneous and showed greater IV enhancement on CT. All esophageal GISTs showed marked avidity (mean maximum standardized uptake value, 16) on PET scans. All esophageal GISTs were positive for c-KIT (a cell-surface transmembrane tyrosine kinase also known as CD117) and CD34. On histopathology, six esophageal GISTs (75%) were of the spindle pattern and two (25%) were of a mixed spindle and epithelioid pattern. Five esophageal GISTs had exon 11 mutations (with imatinib sensitivity). Clinical outcome correlated with treatment strategy (resection plus adjuvant therapy or resection alone) rather than risk stratification. CONCLUSION Esophageal GISTs are unusual but clinically important mesenchymal neoplasms. Although esophageal GISTs and

To characterize patients who suffer perforation in the context of eosinophilic esophagitis (EoE) and to identify predictors of perforation. Esophageal perforation is a serious complication of EoE. We conducted a retrospective cohort study of the University of North Carolina EoE clinicopathologic database from 2001 to 2014. Subjects were included if they had an incident diagnosis of EoE and met consensus guidelines, including nonresponse to a PPI trial. Patients with EoE who had suffered perforation at any point during their course were identified, and compared with EoE cases without perforation. Multiple logistic regression was performed to determine predictors of perforation. Out of 511 subjects with EoE, 10 (2.0%) had experienced an esophageal perforation. Although those who perforated tended to have a longer duration of symptoms before diagnosis (11.4 vs. 7.0 y, P=0.13), a history of food impaction (odds ratio, 14.9; 95% confidence interval, 1.7-129.2) and the presence of a focal stricture (odds ratio, 4.6; 95% confidence interval, 1.1-19.7) were the only factors independently associated with perforation. Most perforations (80%) occurred after a prolonged food bolus impaction, and only half of individuals (5/10) carried a diagnosis of EoE at the time of perforation; none occurred after dilation. Six patients (60%) were treated with nonoperative management, and 4 (40%) required surgical repair. Esophageal perforation is a rare but serious complication of eosinophilic esophagitis, occurring in ∼2% of cases. Most episodes are due to food bolus impaction or strictures, suggesting that patients with fibrostenotic disease due to longer duration of symptoms are at increased risk.

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. 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. 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. 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.

Cancer of the esophagus is an underestimated, poorly understood, and changing disease. Its overall 5-year survival is less than 20%, even in the United States, which is largely a function of a delay in diagnosis until its more advanced stages. Additionally, the epidemiologic complexities of esophageal cancer are vast, rendering screening and prevention limited at best. First, the prevalence of esophageal cancer is unevenly distributed throughout the world. Second, the two histological forms (squamous cell and adenocarcinoma) vary in terms of their geographic prevalence and associated risk factors. Third, some populations appear at particular risk for esophageal cancer. And fourth, the incidence of esophageal cancer is in continuous flux among groups. Despite the varied prevalence and risks among populations, some factors have emerged as consistent associations while others are only now becoming more fully recognized. The most prominent, scientifically supported, and long-regarded risk factors for esophageal cancer are tobacco, alcohol, and reflux esophagitis. Inasmuch as the above are regarded as important risk factors for esophageal cancer, they are not the sole contributors. Dietary habits, nutrition, local customs, and the environment may be contributory. Along these lines, vitamins, minerals, fruits, vegetables, meats, fats, salted foods, nitrogen compounds, carcinogens, mycotoxins, and even the temperature of what we consume are increasingly regarded as potential etiologies for this deadly although potentially preventable disease. The goal of this review is to shed light on the less known role of nutrition and dietary habits in esophageal cancer. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

Enhanced characterization of esophageal peristaltic and sphincter function provided by esophageal pressure topography (EPT) offers a potential diagnostic advantage over conventional line tracings (CLT). However, high-resolution manometry (HRM) and EPT require increased equipment costs over conventional systems and evidence demonstrating a significant diagnostic advantage of EPT over CLT is limited. Our aim was to investigate whether the inter-rater agreement and/or accuracy of esophageal motility diagnosis differed between EPT and CLT. Forty previously completed patient HRM studies were selected for analysis using a customized software program developed to perform blinded independent interpretation in either EPT or CLT (six pressure sensors) format. Six experienced gastroenterologists with a clinical focus in esophageal disease (attendings) and six gastroenterology trainees with minimal manometry experience (fellows) from three academic centers interpreted each of the 40 studies using both EPT and CLT formats. Rater diagnoses were assessed for inter-rater agreement and diagnostic accuracy, both for exact diagnosis and for correct identification of a major esophageal motility disorder. The total group agreement was moderate (κ=0.57; 95% CI: 0.56-0.59) for EPT and fair (κ=0.32; 0.30-0.33) for CLT. Inter-rater agreement between attendings was good (κ=0.68; 0.65-0.71) for EPT and moderate (κ=0.46; 0.43-0.50) for CLT. Inter-rater agreement between fellows was moderate (κ=0.48; 0.45-0.50) for EPT and poor to fair (κ=0.20; 0.17-0.24) for CLT. Among all raters, the odds of an incorrect exact esophageal motility diagnosis were 3.3 times higher with CLT assessment than with EPT (OR: 3.3; 95% CI: 2.4-4.5; P<0.0001), and the odds of incorrect identification of a major motility disorder were 3.4 times higher with CLT than with EPT (OR: 3.4; 2.4-5.0; P<0.0001).

Gastro-esophageal reflux (GER) is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD). Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines.

Esophageal foreign body impaction (EFBI) is a common problem requiring urgent endoscopy. EFBI may be the first sign of underlying esophageal pathology, yet mucosal biopsies are rarely performed. We report a retrospective analysis of 572 children requiring removal of an EFBI over a 12-year period by pediatric otolaryngologists (ENT), surgeons (PS), and gastroenterologists (PGI). The method of removal [direct laryngoscopy (DL), rigid endoscopy (RE), flexible endoscopy (FE)], type of foreign body (inanimate or food), whether mucosal biopsies were performed, and histologic findings of biopsy samples were recorded for each patient. Foreign body removal was most commonly performed by PGI (298 [52 %]); the remaining were equally distributed between ENT (136 [24 %]) and PS (138 [24 %]). The method of foreign body removal used by ENT was RE (89 %), DL (8 %), and FE (3 %). Pediatric surgery preferred FE (62 %), followed by RE (27 %) and DL (11 %). Pediatric gastroenterology used FE exclusively. Esophageal biopsies were never performed by ENT or PS; PGI performed esophageal biopsies more commonly in children with meat bolus impactions (50 %) than in children with inanimate foreign bodies (12 %). Mucosal pathology was more common in children with meat bolus impaction (100 %) than in children with inanimate foreign bodies (45 %). Esophageal mucosal biopsy should be considered for all children with EFBI not attributed to stricture, particularly those with meat bolus impaction.

ABSTRACT Introduction: Contrast computed tomography and magnetic resonance imaging are widely used due to its image quality and ability to study pancreatic and peripancreatic morphology. The understanding of the various subtypes of the disease and identification of possible complications requires a familiarity with the terminology, which allows effective communication between the different members of the multidisciplinary team. Aim: Demonstrate the terminology and parameters to identify the different classifications and findings of the disease based on the international consensus for acute pancreatitis ( Atlanta Classification 2012). Methods: Search and analysis of articles in the "CAPES Portal de Periódicos with headings "acute pancreatitis" and "Atlanta Review". Results: Were selected 23 articles containing radiological descriptions, management or statistical data related to pathology. Additional statistical data were obtained from Datasus and Population Census 2010. The radiological diagnostic criterion adopted was the Radiology American College system. The "acute pancreatitis - 2012 Rating: Review Atlanta classification and definitions for international consensus" tries to eliminate inconsistency and divergence from the determination of uniformity to the radiological findings, especially the terminology related to fluid collections. More broadly as "pancreatic abscess" and "phlegmon" went into disuse and the evolution of the collection of patient fluids can be described as "acute peripancreatic collections", "acute necrotic collections", "pseudocyst" and "necrosis pancreatic walled or isolated". Conclusion: Computed tomography and magnetic resonance represent the best techniques with sequential images available for diagnosis. Standardization of the terminology is critical and should improve the management of patients with multiple professionals care, risk stratification and adequate treatment. PMID:27759788

Every year more insight into the pathogenesis and treatment of esophageal motor disorders is obtained. This review highlights some interesting literature published in this area during the last year. Longitudinal and circular muscle contractions act in a well coordinated fashion to allow normal peristalsis. Techniques such as intraluminal impedance, high-resolution manometry and intraluminal ultrasound provide useful additional information on esophageal function both in the normal and abnormal situation. The dynamics of the gastroesophageal junction can be studied with a newly developed probe, and the mechanism behind transient lower esophageal sphincter relaxations is still being unravelled. New manometric criteria for nutcracker esophagus have been proposed, whereas further evidence is reported supporting an association between diabetes mellitus and cardiovascular disease and esophageal dysmotility and spasm, respectively. Finally, several long-term follow-up results of surgical myotomy and pneumodilatation have been reported. Due to the perfection of esophageal measuring techniques, our knowledge of esophageal function continues to increase. The studies reviewed here provide interesting information on the pathogenesis and treatment of several esophageal motor disorders.

To retrospectively evaluate which dose-volumetric parameters are associated with the risk of > or = Grade 3 acute esophageal toxicity (AET) in lung cancer patients treated with three-dimensional conformal radiotherapy (3D-CRT). One hundred twenty-four lung cancer patients treated curatively with 3D-CRT were retrospectively analyzed. All patients received conventionally fractionated radiotherapy (RT) with median dose of 60 Gy (range, 54-66 Gy) delivered in 30 fractions (range, 27-33 fractions). Thirty-one patients underwent curative surgery before RT. Ninety-two patients received chemotherapy (induction, 18; concurrent +/- induction, 74). Acute esophageal toxicity was scored by Radiation Therapy Oncology Group criteria. The parameters analyzed included sex; age; Karnofsky performance score; weight loss; surgery; concurrent chemotherapy; the percentages of organ volume receiving > or =20 Gy (V20), > or =30 Gy (V30), > or =40 Gy (V40), > or =50 Gy (V50), > or =55 Gy (V55), > or = 58 Gy (V58), > or =60 Gy (V60), and > or =63 Gy (V63); the percent and absolute length of the esophagus irradiated; the maximum and mean dose to the esophagus; and normal tissue complication probability. Of the 124 patients, 15 patients (12.1%) had Grade 3 AET, and 1 (0.8%) patient had Grade 4 AET. There was no fatal Grade 5 AET. In univariate and multivariate logistic regression analyses, concurrent chemotherapy and V60 were significantly associated with the development of severe (> or = Grade 3) AET (p < 0.05). Severe AET was observed in 15 of 74 patients (20.3%) who received concurrent chemotherapy, and in 1 of 50 patients (2.0%) who did not (p = 0.002). Severe AET was observed in 5 of 87 patients (5.7%) with V60 < or = 30% and in 11 of 37 patients (29.7%) with V60 > 30% (p < 0.001). Among 50 patients who did not receive concurrent chemotherapy, severe AET was observed in 0 of 43 patients (0%) with V60 < or = 30% and in 1 of 7 patients (14.2%) with V60 > 30% (p = 0.140).

An original technique using laparoscopic instruments in a gastric endocavitary work chamber with potential for esophagus, stomach and D1 vizualisation. The main purpose of laparagastroscopy is to improve the quality of life of the patient disabling by the esophageal tumor. This method has several advantages: providing physiological feeding, harvesting materials for histopathological examination, solving eso-tracheal fistulas concurrently with the proposed operation and hemostatic role through compression, low energy and plastic consumption, rapid socio-economic reintegration, mental psychological care of the patient. Patients and Methods: The paper deals with 162 cases with different tumors of the esophagus, patients with different grades of esophageal stenosis, different stages of esophageal neoplasm. Both the patients with eso-tracheal fistulas and those with gastro- or jejunostoma were included. Results: From 162 cases, 33 cases (20%) with cervical esophageal neoplasm, 66 (41%) cases with thoracic esophageal neoplasm and 63 (39%) cases with abdominal esophageal neoplasm. The histopathological type is 37% adenocarcinomas and 63% squamous carcinomas. From total number of cases, 87 (54%) had no metastasis, and 75 (46%) had secondary determinations. The most frequent localization of metastasis was pulmonary, followed by liver (Fig. 1) and bone. The analysis of this intervention has shown that complications have been much lower both in terms of their numerical value and their severity, a longer survival time with a much higher satisfaction index is ensured. Esophageal endoprosthesis (EPE) through laparagastroscopic approach should be a a reserve procedure instead of a disabling gastrostomy or jejunostomy. EPE is an extremely effective procedure specially by keeping the physiology of food bowl. The approach is minimally invasive with minimal attack on the body with significant plastic and aesthetic reductions. This procedure allows the prosthesis to be viewed both

The purpose of this retrospective study was to clarify the predictive factors correlated with esophageal stenosis within three months after radiation therapy for locally advanced esophageal cancer. We enrolled 47 patients with advanced esophageal cancer with T2-4 and stage II-III who were treated with definitive radiation therapy and achieving complete response of primary lesion at Kyushu University Hospital between January 1998 and December 2005. Esophagography was performed for all patients before treatment and within three months after completion of the radiation therapy, the esophageal stenotic ratio was evaluated. The stenotic ratio was used to define four levels of stenosis: stenosis level 1, stenotic ratio of 0-25%; 2, 25-50%; 3,50-75%; 4,75-100%. We then estimated the correlation between the esophageal stenosis level after radiation therapy and each of numerous factors. The numbers and total percentages of patients at each stenosis level were as follows: level 1: n = 14 (30%); level 2: 8 (17%); level 3: 14 (30%); and level 4: 11 (23%). Esophageal stenosis in the case of full circumference involvement tended to be more severe and more frequent. Increases in wall thickness tended to be associated with increases in esophageal stenosis severity and frequency. The extent of involved circumference and wall thickness of tumor region were significantly correlated with esophageal stenosis associated with tumor regression in radiation therapy (p = 0.0006, p = 0.005). For predicting the possibility of esophageal stenosis with tumor regression within three months in radiation therapy, the extent of involved circumference and esophageal wall thickness of the tumor region may be useful.

Should patients with esophageal atresia be submitted to esophageal substitution before they start walking?

Esophagocoloplasty and gastric transposition are two major methods for esophageal substitution in children with esophageal atresia, and there is broad agreement that these operations should not be performed before the children start walking. However, there are some reported advantages of performing such operations in the first months of life or in the neonatal period. In this study, we compared our experience with esophageal substitution procedures performed in walking children with esophageal atresia, with the outcomes of children who had the operation before the third month of life reported in the literature. The purpose of this study was to establish if we have to wait until the children start walking before indicating the esophageal replacement procedure. From February 1978 to October 2009, 129 children with esophageal atresia underwent esophageal replacement in our hospital (99 colonic interpositions and 30 gastric transpositions). The records of these patients were reviewed for data regarding demographics, complications (leaks, graft failures, strictures, and graft torsion), and mortality and compared with those reported in the two main articles on esophageal replacement in the neonatal period or in patients less than 3 months of age. The main complication of our casuistic was cervical anastomosis leakage, which sealed spontaneously in all except in four patients. One patient of the esophagocoloplasty group developed graft necrosis and three patients in the gastric transposition group had gastric outlet obstruction, secondary to axial torsion of the stomach placed in the retrosternal space. The long-term outcome of the patients in both groups was considered good to excellent in terms of normal weight gain, absence of dysphagia, and other gastrointestinal symptoms. The comparisons of the main complications and mortality rates in walking children with esophageal substitutions performed in the first months of life showed that the incidences of cervical

An increasing number of patients are diagnosed with esophageal cancer at an advanced stages, and only a small group of them can benefit from the traditional chemotherapy and radiotherapy. So far, multiple monoclonal antibodies and tyrosine kinase inhibitors have been developed, alone or in combination with traditional therapy, to improve the prognosis of patients with advanced esophageal cancer. This review summarizes the recent advances of targeted therapies against EGFR, HER2, VEGFR and c-MET in esophageal cancer. More clinical trials should be performed to evaluate the efficacy and safety of various targeted therapy regimens. Future basic research should focus on investigating the molecular mechanisms of therapeutic targets in esophageal cancer.

Hyperinsulinemia could have a role in the growing incidence of esophageal adenocarcinoma (EAC) and its pre-cancerous lesion, Barrett’s Esophagus, a possible consequence of Gastro-Esophageal Reflux Disease. Obesity is known to mediate esophageal carcinogenesis through different mechanisms including insulin-resistance leading to hyperinsulinemia, which may mediate cancer progression via the insulin/insulin-like growth factor axis. We used the hyperinsulinemic non-obese FVB/N (Friend leukemia virus B strain) MKR (muscle (M)-IGF1R-lysine (K)-arginine (R) mouse model to evaluate the exclusive role of hyperinsulinemia in the pathogenesis of EAC related to duodeno-esophageal reflux.

Thirty weeks after surgery, the esophagus was processed for histological, immunological and insulin/Insulin-like growth factor 1 (IGF1) signal transduction analyses. Most of the WT mice (63.1%) developed dysplasia, whereas most of the MKR mice (74.3%) developed squamous cell and adenosquamous carcinomas, both expressing Human Epidermal growth factor receptor 2 (HER2).

Hyperinsulinemia could have a role in the growing incidence of esophageal adenocarcinoma (EAC) and its pre-cancerous lesion, Barrett's Esophagus, a possible consequence of Gastro-Esophageal Reflux Disease. Obesity is known to mediate esophageal carcinogenesis through different mechanisms including insulin-resistance leading to hyperinsulinemia, which may mediate cancer progression via the insulin/insulin-like growth factor axis. We used the hyperinsulinemic non-obese FVB/N (Friend leukemia virus B strain) MKR (muscle (M)-IGF1R-lysine (K)-arginine (R) mouse model to evaluate the exclusive role of hyperinsulinemia in the pathogenesis of EAC related to duodeno-esophageal reflux. FVB/N wild-type (WT) and MKR mice underwent jejunum-esophageal anastomosis side-to end with the exclusion of the stomach. Thirty weeks after surgery, the esophagus was processed for histological, immunological and insulin/Insulin-like growth factor 1 (IGF1) signal transduction analyses.

The aim of the study was to measure clinicopathological features of children presenting to a tertiary care emergency department with esophageal food impaction. A retrospective chart review of children with esophageal food impaction seen between January 1, 2005 and June 30, 2009, including all patients from age 1 month to 18 years with esophageal food impaction at a pediatric emergency department, was performed. Initial screening of International Classification of Disease, 9th Revision, discharge diagnosis identified 698 children with an esophageal foreign body. Of this group, 72 esophageal food impaction events were identified in 65 children (69% boys), 49 of whom required endoscopic intervention. Endoscopic appearances of the esophageal mucosa were abnormal in 40 (82%), revealing evidence of esophagitis (55%) or stricture (27%). Twenty-four of the subjects had biopsies taken at the time of endoscopy. Inflammation, described as increased eosinophils, basilar hyperplasia, rete peg elongation, and/or microabscess, was present in 76% of mucosal samples. Follow-up endoscopy in 12 children identified an etiology in 9, five of whom were found to have eosinophilic esophagitis. The majority of children with esophageal food impaction who underwent endoscopic evaluation and biopsy have an underlying potentially treatable cause. We therefore recommend that all of the children with esophageal food impaction have mucosal biopsies at the time of endoscopic disimpaction with appropriate follow-up to allow for diagnosis and management of the underlying etiology.

Deglutitive Inhibition, Latency Between Swallow and Esophageal Contractions and Primary Esophageal Motor Disorders

PubMed Central

Jafari, Jafar

2012-01-01

Swallowing induces an inhibitory wave that is followed by a contractile wave along the esophageal body. Deglutitive inhibition in the skeletal muscle of the esophagus is controlled in the brain stem whilst in the smooth muscle, an intrinsic peripheral control mechanism is critical. The latency between swallow and contractions is determined by the pattern of activation of the inhibitory and excitatory vagal pathways, the regional gradients of inhibitory and excitatory myenteric nerves, and the intrinsic properties of the smooth muscle. A wave of inhibition precedes a swallow-induced peristaltic contraction in the smooth muscle part of the human oesophagus involving both circular and longitudinal muscles in a peristaltic fashion. Deglutitive inhibition is necessary for drinking liquids which requires multiple rapid swallows (MRS). During MRS the esophageal body remains inhibited until the last of the series of swallows and then a peristaltic contraction wave follows. A normal response to MRS requires indemnity of both inhibitory and excitatory mechanisms and esophageal muscle. MRS has recently been used to assess deglutitive inhibition in patients with esophageal motor disorders. Examples with impairment of deglutitive inhibition are achalasia of the LES and diffuse esophageal spasm. PMID:22323983

The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment. In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months. There was a significant difference in the rate of positive methacholine test between the cases (40%) and the controls (6.7%) prior to anti-acid therapy (P < 0.0001). After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05) but did not change in the controls (P = 0.15). The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

Elective nodal irradiation (ENI) might improve overall survival in patients with inoperable esophageal cancer. We conducted a retrospective analysis to assess the long-term survival and toxicity of esophageal cancer patients treated with ENI versus conventional-field irradiation (CFI). All data in the present study were based on our institutional experience from 2000 to 2005 of patients with inoperable esophageal cancer treated with ENI or CFI plus two concurrent cycles of paclitaxel/cisplatin. Based on the inclusion and exclusion criteria, 89 patients were included in the analysis. Of these patients, 51 were treated with ENI, whereas 38 were treated with CFI. For the per-protocol population, the patients in the ENI group significantly improved in terms of their 10-year disease-specific overall survival (43.1% vs 10.5%, P = 0.019), 10-year disease-free survival (36.7% vs 10.2%, P = 0.040) and 10-year local recurrence-free survival (47.2% vs 17.2%, P = 0.018) compared with the CFI group. Aside from radiation esophagitis, the incidence of grade 3 or greater acute toxicities did not differ between the two groups. Multivariate analysis showed that radiation field, tumor length and clinical stage were independent prognostic factors associated with OS. Concurrent chemoradiotherapy with ENI improves both disease-specific overall survival and loco-regional control in patients with inoperable esophageal cancer receiving per-protocol treatment. The regimen has a manageable tolerability profile. © 2017 The Authors. Cancer Science published by John Wiley & Sons Australia, Ltd on behalf of Japanese Cancer Association.

Hoffman, Ilse; De Greef, Toon; Haesendonck, Nancy; Tack, Jan

2010-06-01

Motility abnormalities in adults with gastroesophageal reflux disease (GERD) include nontransmitted contractions, reduced distal esophageal contraction amplitude, and simultaneous contractions. Information on esophageal body motility in children with GERD is scarce. Our aim was to study esophageal motility patterns in children with GERD, taking into account the presence of anatomical abnormalities and neurological impairment, the effect of age on esophageal motility in GERD, and the relation between esophageal manometry and GERD severity parameters (acid exposure and presence of esophagitis). Consecutive children referred for severe GER(D) symptoms underwent a barium swallow, upper endoscopy, pH monitoring, and stationary water-perfused esophageal manometry. Mean lower esophageal sphincter (LES) pressure and velocity of propagation in the proximal and distal esophagus decreased with age in this group of children with GERD (all P < 0.01). Severely disturbed esophageal motility was found in children with previous esophageal atresia. Patients with psychomotor retardation had significantly lower occurrence of peristaltic waves (94% +/- 21% vs 79% +/- 38%; P = 0.001), distal propagation velocity (0.8 +/- 0.4 vs 0.6 +/- 0.5 cm/s; P = 0.05), and distal contraction duration (3.1 +/- 0.8 vs 3.4 +/- 1 seconds; P = 0.05). None of the manometric characteristics differed between patients with normal or abnormal esophageal pH monitoring or with or without erosive esophagitis. LES pressure and esophageal velocity decreased with increasing age. Esophageal manometry is severely impaired in children with esophageal atresia and psychomotor retardation. No specific esophageal motor abnormalities related to the presence of endoscopic esophagitis or abnormal pH monitoring were found.

In T4 esophageal cancer with tracheobronchial invasion, an esophagorespiratory fistula (ERF) often occurs during or after chemoradiotherapy. We have performed esophageal bypass operations prior to definitive chemoradiotherapy for these patients to increase the chemoradiotherapy completion rate by minimizing the potential effect of an ERF. The aim of this study was to examine the clinical outcome of esophageal bypass surgery prior to chemoradiotherapy. Between 1997 and 2010, 17 patients underwent esophageal bypass surgery followed by definitive chemoradiotherapy for esophageal cancer with tracheobronchial invasion (bypass group). Ten patients in the same circumstances were treated with chemoradiotherapy alone (control group). Overall survival, the clinical effect of chemoradiotherapy, the ERF incidence rate, and the safety of esophageal bypass surgery were assessed. The overall response rate to chemoradiotherapy was 64.7% in the bypass group and 90.0% in the control group. Except for 2 patients with ERF at initial diagnosis, 4 (26.7%) of the 15 patients developed ERF in the bypass group, and 3 (30.0%) of the 10 patients developed ERF in the control group during or after chemoradiotherapy. The 2-year and 3-year overall survival rates were 17.6% and 17.6% in the bypass group and 20.0% and 0% in the control group, respectively (p = 0.924); long-term survival of more than 3 years was seen only in the bypass group. Esophageal bypass surgery prior to definitive chemoradiotherapy could be performed safely, and this strategy contributed to long-term survival in the patients who achieved a good response to chemoradiotherapy but developed an ERF.

The objective of this study was to review the clinical experience of temporarily placing an endoesophageal silicone salivary bypass stent and its value in managing patients with life-threatening esophageal disruptions. Clinical records of patients undergoing placement of silicone Montgomery salivary bypass stents from June 1998 to September 2007 were reviewed. Seventeen patients had a proven esophageal disruption in the absence of malignancy and with life-threatening sepsis refractory to conventional management. Underlying conditions were iatrogenic trauma from prior pulmonary surgery (4 patients), significant anastomotic leaks after an esophagogastrectomy (4 patients), delayed presentation (> 24 hours) of a perforated esophagus (4 patients), leak after esophageal surgery (3 patients), and esophagobronchial fistula secondary to inflammation and infection (2 patients). Stents were placed without securing, were sutured in place to the esophageal wall at the time of thoracotomy, or were secured by bringing holding sutures through the nostrils and tied over the bridge of the nose. In all cases, placement of the esophageal stent led to prompt improvement of the leak and, within a week, improvement of the sepsis. Supportive measures were continued after placement of the stent. Sixteen patients overcame the sepsis with ultimate healing of the esophageal disruption (13 patients) or maturation of the perforation into a chronic fistula (3 patients). Endoscopic stent removal was performed 2 to 16 weeks after placement. No patient had a stricture develop at the disruption site. One patient died of ruptured thoracic aorta. Silicone salivary bypass stents serve as an effective way of diverting and excluding the oral-alimentary stream, thereby providing optimal conditions for sepsis control. They are a useful adjunct in the management of complex esophageal conditions.

Purpose: To determine the risk factors for acute esophagitis (AE) in non-small-cell lung cancer (NSCLC) patients treated with concurrent chemotherapy (CCT) and three-dimensional conformal radiotherapy (3D-CRT). Methods and Materials: Clinical data were retrospectively analyzed for 215 NSCLC patients treated with CCT and 3D-CRT during 2000-2003, 127 of whom also had induction chemotherapy (ICT). Carboplatin and paclitaxel were the most commonly used agents for both ICT and CCT. The median prescription dose of radiotherapy was 63.5 Gy in 35 fractions. AE was graded during each treatment week and 1-month follow-up visits. The factors related to clinical and disease characteristics, CCT andmore » 3D-CRT treatments, and treatment planning were reviewed and analyzed for their association with Grade {>=}3 AE using univariate and multivariate logistic tests. Results: The rate of any grade AE was 93.0% and of Grade {>=}3 was 20.5%. Univariate analyses showed that none of the clinical factors was significantly associated with Grade {>=}3 AE. However, the mean radiation dose to the esophagus, the absolute esophageal volume treated above 15 Gy (aV15) through aV45 Gy, and the relative esophagus volume treated above 10 Gy (rV10) through rV45 Gy were significant risk factors for Grade {>=}3 AE. Only rV20 was retained as the single risk factor in multivariate analyses. Conclusions: The risk of AE in the NSCLC patients treated with CCT and 3D-CRT was primarily determined by dosimetric factors. These factors should be carefully considered during treatment planning to minimize the incidence of AE.« less

Purpose Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR) brachytherapy was applied prior to definitive radiochemotherapy. Material and methods In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma) were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT) and concurrent chemotherapy with cisplatin/5-fluorouracil. Results Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%). Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Conclusions Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT. PMID:28344601

Esophageal cancer is the eighth most common cancer worldwide, and the incidence of esophageal carcinoma is rapidly increasing. With the advent of new staging and treatment techniques, esophageal cancer can now be managed through various strategies. A good understanding of the advances and limitations of new staging techniques and how these can guide in individualizing treatment is important to improve outcomes for esophageal cancer patients. This paper outlines the recent progress in staging and treatment of esophageal cancer, with particularly attention to endoscopic techniques for early-stage esophageal cancer, multimodality treatment for locally advanced esophageal cancer, assessment of response to neoadjuvant treatment, and the role of cervical lymph node dissection. Furthermore, advances in robot-assisted surgical techniques and postoperative recovery protocols that may further improve outcomes after esophagectomy are discussed. © 2016 The Authors.

Nonerosive reflux disease (NERD) is a highly prevalent phenotype of the gastroesophageal reflux disease. In this study, we developed a novel murine model of NERD in mice with microscopic inflammation and impairment in the epithelial esophageal barrier. Female Swiss mice were subjected to the following surgical procedure: the transitional region between the forestomach and the glandular portion of the stomach was ligated, and a nontoxic ring was placed around the duodenum near the pylorus. The control group underwent sham surgery. The animals were euthanized at 1, 3, 7, and 14 days after surgery. Survival and body weight were monitored daily. Esophageal wet weight, macroscopic lesion, histopathological alterations, myeloperoxidase (MPO) activity, cytokine levels, transepithelial electrical resistance (TEER), and mucosal permeability were evaluated. The survival rate was 78% at 14 days, with mild loss in body weight. Surgery did not induce erosive esophagitis but instead induced microscopic inflammation and increased esophageal wet weight, IL-6, keratinocyte-derived cytokine (KC) levels, and MPO activity with maximal peak between 3 and 7 days and resolution at 14 days postsurgery. Epithelial esophageal barrier was evaluated in operated mice at 7 and 14 days postsurgery; a decrease in TEER and increase in the esophageal epithelial permeability were observed compared with the sham-operated group. In addition, the inhibition of acid secretion with omeprazole significantly prevented the esophageal inflammation and impairment of barrier function at 7 days postsurgery. Thus we established a novel experimental model of NERD in mice, which can contribute to understanding the pathophysiological events associated with NERD. NEW & NOTEWORTHY In this study, we standardized an experimental model of nonerosive reflux disease (NERD) in mice. This model involves an acute inflammatory response followed by impaired esophageal mucosal integrity, even in the absence of inflammation

Minimally invasive surgery for esophageal achalasia

2006-01-01

Esophageal achalasia is the most commonly diagnosed primary esophageal motor disorder and the second most common functional esophageal disorder. Current therapy of achalasia is directed toward elimination of the outflow resistance caused by failure of the lower esophageal sphincter to relax completely upon swallowing. The advent of minimally invasive surgery has nearly replaced endoscopic pneumatic dilation as the first-line therapeutic approach. In this editorial, the rationale and the evidence supporting the use of laparoscopic Heller myotomy combined with fundoplication as a primary treatment of achalasia are reviewed. PMID:17009388

Esophageal achalasia can be roughly divided into non-sigmoid and sigmoid types. Laparoscopic surgery has been reported to be less than optimally effective for sigmoid type. The aim of this study was to examine the impact of the esophageal flexion level on the clinical condition and surgical outcomes of patients with sigmoid esophageal achalasia. The subjects were 36 patients with sigmoid esophageal achalasia who had been observed for >1 year after surgery. The subjects were divided into sigmoid type (Sg) and advanced sigmoid type (aSg) groups based on the flexion level of the lower esophagus to compare their clinical parameters and surgical outcomes. The Sg and aSg groups included 26 (72%) and 10 subjects, respectively. There were no marked differences in the clinical parameters or surgical outcomes between the two groups. However, the clearance rate calculated using the timed barium esophagogram was lower in the aSg group than in the Sg group. No differences were found in the postoperative symptom scores between the two groups, and both reported a high level of satisfaction. Although laparoscopic surgery for symptoms of sigmoid esophageal achalasia was highly successful regardless of the flexion level, the improvement in esophageal clearance was lower when the flexion level was higher.

Background: The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment. Materials and Methods: In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months. Results: There was a significant difference in the rate of positive methacholine test between the cases (40%) and the controls (6.7%) prior to anti-acid therapy (P < 0.0001). After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05) but did not change in the controls (P = 0.15). Conclusion: The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

Feeding Difficulties in Children with Esophageal Atresia.

PubMed

Mahoney, Lisa; Rosen, Rachel

2016-06-01

The current available literature evaluating feeding difficulties in children with esophageal atresia was reviewed. The published literature was searched through PubMed using a pre-defined search strategy. Feeding difficulties are commonly encountered in children and adults with repaired esophageal atresia [EA]. The mechanism for abnormal feeding includes both esophageal and oropharyngeal dysphagia. Esophageal dysphagia is commonly reported in patients with EA and causes include dysmotility, anatomic lesions, esophageal outlet obstruction and esophageal inflammation. Endoscopic evaluation, esophageal manometry and esophograms can be useful studies to evaluate for causes of esophageal dysphagia. Oropharyngeal dysfunction and aspiration are also important mechanisms for feeding difficulties in patients with EA. These patients often present with respiratory symptoms. Videofluoroscopic swallow study, salivagram, fiberoptic endoscopic evaluation of swallowing and high-resolution manometry can all be helpful tools to identify aspiration. Once diagnosed, management goals include reduction of aspiration during swallowing, reducing full column reflux into the oropharynx and continuation of oral feeding to maintain skills. We review specific strategies which can be used to reduce aspiration of gastric contents, including thickening feeds, changing feeding schedule, switching formula, trialing transpyloric feeds and fundoplication.

Esophageal perforation is the most serious adverse event of pneumatic dilation (PD) for achalasia; it is usually managed by surgical repair. We investigated risk factors for esophageal perforation after PD and evaluated safety and long-term outcome of nonsurgical management strategies. We analyzed medical records of patients with achalasia who were treated with PD from 1992-2010 at the University Hospital Gasthuisberg in Leuven, Belgium; all patients with esophageal perforation were contacted to determine long-term outcomes. Achalasia outcomes were assessed by using the Vantrappen criteria. Of 830 PD procedures performed on 372 patients with manometry-confirmed achalasia (57 ± 1 years, 51% male), 16 were complicated by transmural esophageal perforation (4.3% of patients, 1.9% of dilations). Age >65 years was the only significant risk factor for complications (odds ratio, 3.5; 95% confidence interval, 1.2-10.2). All patients were treated conservatively with broad-spectrum antibiotics and nothing by mouth. In 6 patients (38%) the clinical course was further complicated by a pleural effusion, which required a drain in 4 patients. One patient (6%) died of mediastinal hemorrhage within 12 hours after PD. Patients with complications were discharged after 19 ± 2.3 days, compared with 4 ± 0.2 days for those without complications (P < .0001). Long-term outcomes (mean follow-up, 84 ± 14 months) were determined for 12 patients (75%); 11 had excellent or good outcomes (69%), and 1 had a moderate outcome (6%). Age >65 years is a significant risk factor for esophageal perforation after PD. Nonsurgical management of transmural esophageal tears is feasible, with favorable short-term and long-term outcomes, but is not devoid of complications. Copyright © 2012 AGA Institute.

Few studies have examined the incidence of complications from gastro-esophageal reflux disease (GERD) in children and adolescents in primary care. Here we aimed to describe the natural history of GERD in a pediatric population with no reflux esophagitis at initial diagnosis, assessing diagnoses of new esophageal complications and extra-esophageal conditions. We used The Health Improvement Network UK primary care database (which includes data on more than 2 million patients) to identify individuals aged 1-17 years with a first diagnosis of gastro-esophageal reflux or heartburn in the period 2000-2005, via a computerized search followed by a manual review of the patient records. This search identified 1242 individuals with an incident diagnosis of GERD but no record of esophagitis. This cohort was followed-up to detect new diagnoses of esophageal complications and extra-esophageal conditions. During a mean follow-up period of almost 4 years, 40 children and adolescents had a confirmed new diagnosis of reflux esophagitis (incidence: 10.9 per 1000 person-years). No cases of Barrett's esophagus, esophageal stricture or esophageal ulcer were reported. Individuals with GERD had double the risk of an extra-esophageal condition such as asthma, pneumonia, cough or chest pain compared with children and adolescents with no diagnosis of GERD. Children and adolescents with GERD may be at risk of developing reflux esophagitis and a range of other extra-esophageal conditions, but more severe esophageal complications are rare.

Esophagorespiratory fistula (ERF) caused by esophageal carcinoma is a fatal complication. In our institution, esophageal bypass surgery has been indicated when possible. We herein retrospectively describe the clinical results of esophageal bypass surgery for ERF. Between April 2001 and March 2015, 20 patients with ERF underwent esophageal bypass surgery. For these patients, the clinical safety, validity, and effectiveness of esophageal bypass surgery were examined and compared with the results of bypass surgery without ERF. Eight patients developed ERF at the initial diagnosis, while 10 patients developed ERF during and after chemoradiotherapy. Postoperative complications such as pneumonia, surgical site infection, and anastomotic leakage developed in 12, 5, and 1 patient, respectively. All the patients could eat solid foods at a median of 9 postoperative days. Two patients died within 30 days after the operation and 1 patient developed in-hospital death. Fourteen patients received chemo(radio)therapy after the operation. The median overall survival was 244 days and the one-year and three-year overall survival rates were 45.7 and 15.3 %, respectively. There was no significant difference in terms of the intraoperative findings, postoperative morbidities, and short-term and long-term clinical results between the two groups. Esophageal bypass surgery for ERF is not considered to be highly invasive or risky compared with bypass surgery without ERF. After the operation, respiratory symptoms caused by ERF may improve and oral intake can be achieved. Esophageal bypass surgery should therefore be aggressively performed for patients with a tolerable performance status.

Assess the safety and efficacy of combined antegrade and retrograde esophageal dilation (CARD) for complete esophageal stenosis following head and neck cancer (HNC) treatment. Review HNC dysphagia management. Retrospective review of all patients undergoing CARD following HNC treatment between May 2001 and September 2008. Forty-five patients were identified for review. Parameters assessed included: ability to obtain intraoperative esophageal patency, complications, number of dilations required, diet, and gastric tube (GT) status. Factors associated with dilation failure were analyzed. Intraoperative esophageal patency was obtained in 91% of patients. Median number of all dilations per patient was three. Median number of CARDs per patient was one. Resumption of oral intake occurred in 36/45 (80%). Diet results included: regular or soft diet 32/45 (71%), GT removal 27/45 (60%), and GT dependence with nothing by mouth 9/45 (20%). Laryngeal and pharyngeal stenosis, radionecrosis, tracheotomy dependence, and elongated stenosis were associated with dilation failure. Complications occurred in 18/63 (29%) CARD procedures: eight pneumomediastinum, seven GT site problems, two esophageal perforations, and one pharyngeal infection. All complications resolved spontaneously or with minimal interventions. CARD was safe and effective. Intraoperative patency was achieved in 91% of patients. Eighty percent resumed oral intake. The majority of patients had their GTs removed and resumed a soft or regular diet. Dilation failure was associated with laryngeal, pharyngeal, and excessively long esophageal stenosis, often resulting from radionecrosis. Complications were minor. CARD should be considered before relegating patients with complete esophageal stenosis to chronic GT dependence or subjecting them to laryngopharyngo esophagectomy.

The effects of sleeve gastectomy on gastro-esophageal reflux and gastro-esophageal motility.

PubMed

Hayat, Jamal O; Wan, Andrew

2014-05-01

Sleeve gastrectomy is an increasingly performed bariatric procedure associated with low morbidity and good short to medium term effects on weight loss and comorbid conditions. Studies assessing the prevalence of post-operative gastro-esophageal reflux disease (GERD), show sleeve gastrectomy may provoke de novo GERD symptoms or worsening of pre-existing GERD. Pathophysiological mechanisms of GERD after sleeve gastrectomy include a hypotensive lower esophageal sphincter, increased gastro-esophageal pressure gradient and intra-thoracic migration of the remnant stomach. A reduction in the compliance of the gastric remnant may provoke an increase in transient lower esophageal sphincter relaxations. Time-resolved MRI suggests relative gastric stasis in the proximal remnant and increased emptying from the antrum. A lack of standardisation of technique, along with heterogeneity of studies assessing GERD may explain the wide variability in reported results. Simultaneous and careful repair of an associated hiatus hernia may result in a reduction in the prevalence of post-operative GERD.

Concurrent chemoradiotherapy (CCRT) has been accepted as the standard non-surgical treatment for esophageal cancer. However, no consistent conclusions have been reached whether elective lymph node irradiation (ENI) should be delivered. Therefore, we performed a systematic review and pooled analysis to evaluate the value of CCRT with ENI. A literature search based on PubMed, Embase and Google Scholar was carried out and all of the studies were evaluated carefully regarding with survival outcomes, response rates, patterns of failure rates and acute/late toxicities. Twenty-two studies were identified based on the criteria: median overall survival time was 21.0 months; pooled response rates were 56.8% (CR) and 85.8% (CR+PR), respectively; residual disease rate, local-regional recurrence rate, distant failure rate and both (local-regional recurrence plus distant failure) rate was 28%, 21%, 11%, and 7%, respectively; hematologic toxicities were the most sever acute toxicities and esophagus-related toxicity was the most common radiation-related toxicity both in acute (15.7%) and late (6.2%) phase. In conclusion, ENI is feasible with acceptable toxicities in esophageal carcinoma and the efficacy should be verified in randomized trials. © 2016 International Society for Diseases of the Esophagus.

The incidence and nature of acute secondary irradiation esophagitis was studied in a series of 38 patients undergoing 60Co teletherapy for carcinoma of the lung. Thirty-four patients were male and four female, with ages ranging from 38 to 78 years. The mediastinum being irradiated in the process, all the patients underwent endoscopy for signs of esophagitis and/or gastritis after a dose of 30-40 Gy was delivered to the esophagus. Eighteen patients complained of dysphagia, but only in 12 of them did endoscopy show esophagitis. Of the remaining patients without complaints five had endoscopic signs of esophagitis. Gastritis was found inmore » 18 cases and confirmed histologically in 14. In 17 cases, esophagitis and/or gastritis were confirmed histologically. It is believed that there is a fairly close correlation among clinical, endoscopic, and histological findings to support the claim that esophagitis in these patients is radiation induced. However, the cause of gastritis is not well understood. Data in the literature suggest that nonsteroid anti-inflammatory agents can act as prophylactic means of preventing radiation esophagitis.« less

Background A malignant tracheoesophageal/bronchoesophageal fistula (TEF) is a life-threatening complication of esophageal squamous cell carcinoma. A feeding gastrostomy/jejunostomy had been the most common treatment method for patients with TEF before the era of stenting. The aim of this retrospective study is to compare the prognosis of esophageal squamous cell carcinoma patients with TEF treated with an esophageal metallic stent to those treated with a feeding gastrostomy/jejunostomy. Methods We retrospectively reviewed a total of 1011 patients with esophageal squamous cell carcinoma between 1996 and 2011 at Kaohsiung Chang Gung Memorial Hospital, and 86 patients with TEF (8.5%) were identified. The overall survival and other clinical data were compared between 30 patients treated with an esophageal metallic stent and 35 patients treated with a feeding gastrostomy/jejunostomy. Results Among the 65 patients receiving either an esophageal metallic stent or a feeding gastrostomy/jejunostomy, univariate analysis showed that treatment modality with an esophageal metallic stent (P = 0.007) and radiotherapy treatment after fistula diagnosis (P = 0.04) were predictive of superior overall survival. In the multivariate comparison, treatment modality with an esophageal metallic stent (P = 0.026, odds ratio: 1.859) represented the independent predictive factor of superior overall survival. There were no significant differences between groups in mean decrease in serum albumin or mean body weight loss. Compared to the feeding gastrostomy/jejunostomy group, a significantly higher proportion of patients in the stenting group (53% versus 14%, P = 0.001) were able to receive chemotherapy within 30 days after fistula diagnosis, indicating better infection control in the stenting group. Conclusions Compared with a feeding gastrostomy/jejunostomy, an esophageal metallic stent significantly improves overall survival in patients with malignant TEF in our retrospective

Spontaneous rupture of the esophagus is a rare but life-threatening thoracic emergency, with high rates of clinical misdiagnosis and mortality. This article summarizes our experience in the treatment of spontaneous esophageal rupture with transnasal thoracic drainage and temporary esophageal stent and jejunal feeding tube placement. We retrospectively assessed the medical records of 19 patients with spontaneous esophageal rupture treated using our intervention protocol. Patients received local anesthesia and sedation prior to undergoing transnasal drainage catheter placement into the thoracic abscess cavity, followed by temporary esophageal stent and jejunal feeding tube placement. After the operation, abscess lavage, nutritional support, and anti-inflammatory treatment were given. The transnasal thoracic drainage catheter, esophageal stent, and feeding tube were removed after the healing of the abscess cavity. In all, 19 covered esophageal stents were placed in 19 patients with spontaneous esophageal rupture. All operations were technically successful. After an average of 84.06 days, the stents were successfully removed from 17 patients. No cases of massive hemorrhage, esophageal rupture, or other complications occurred during stent removal. An 82-year-old patient died of heart failure 2 months after the operation. One patient died of sudden massive hematemesis and hematochezia 55 days after the operation. In one patient, the esophageal injury failed to heal completely. Our treatment protocol is simple, minimally invasive, and efficacious and may be an alternative for patients who are not candidates for surgery, have a high risk of postoperative complications, or wish to undergo minimally invasive surgery.

Congenital esophageal stenosis (CES) can be associated with esophageal atresia/tracheoesophageal fistula (EA/TEF). Because there are a variety of degrees of obstruction and symptoms of CES, it is frequently difficult to make a pre- and post-operative diagnosis of the distal CES associated with EA/TEF. To evaluate the clinical and radiologic features of congenital esophageal stenosis associated with esophageal atresia/tracheoesophageal fistula. We retrospectively reviewed postoperative esophagograms and medical records of 187 children (107 boys, 80 girls) who had primary repair of EA/TEF from 1992 to 2009 at our institution. We evaluated the incidence of CES, clinical findings, radiologic features and management of CES in these children. CES was diagnosed in 22 of 187 EA/TEF children (12%); one child had double CES lesions, for a total of 23 lesions. Ten of those 22 children (45%) had presented with significant symptoms of esophageal obstruction. The diagnosis of CES was delayed in 10 children (45%) until 1-10 years of age. On esophagogram, CES (n = 23) was located in the distal esophagus (n = 20, 87%) or mid-esophagus (n = 3, 13%). The degree of stenosis was severe (n = 6, 26%), moderate (n = 10, 43%), or mild (n = 7, 30%). Eight children, including two with unsuccessful esophageal balloon dilatation of CES, were treated surgically. Histologic examination revealed tracheobronchial remnant (n = 7) or fibromuscular hyperplasia (n = 1). One child with surgically treated CES developed achalasia at the age of 3 years 9 months. Esophagography after EA/TEF repair should be performed with a high index of suspicion for the presence of distal CES, because the diagnosis and adequate management of CES can often be delayed.

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.

Chemoradiotherapy( CRT) for esophageal cancer is a useful modality for both locally advanced and resectable cases. Among adverse events related to CRT, radiation pneumonitis( RP) requires special attention because it has been shown to be occasionally associated with a worse acute prognosis. We report 5 cases of severe RP after CRT. All patients were male, and their mean age was 72 years (range: 66-76 years). The clinical stage of esophageal cancer was I in 1 case, II in 2 cases, and IVa in 2 cases. The mean total radiation dose was 51.8 Gy (range: 43.4-61.4). Initial symptoms and first abnormal findings were a high fever in 4 cases and elevated serum C-reactive protein( CRP) levels in 1 case. No patients presented with respiratory symptoms, including dyspnea and coughing, as initial symptoms. All cases were diagnosed as RP by chest computed tomography examination, an average of 6.8 days after the completion of RT. Four patients required intensive care and were put on ventilator support. All patients received steroid pulse therapy. Two patients recovered from RP; however, 3 died( 1 attributable to multi-organ failure and 2 to respiratory failure). It is important to consider RP caused by CRT when patients present with high fever or elevated CRP levels after the completion of RT for esophageal cancer.

BACKGROUND In the present study, the role and efficiency of strain elastography (SE) were evaluated in diagnosis and staging of acute appendicitis in pediatric patients. MATERIAL AND METHODS We enrolled 225 pediatric patients with suspected clinical and laboratory findings of acute appendicitis. Gray-scale sonographic findings were recorded and staging was made by the colorization method of SE imaging. Appendectomy was performed in all patients and the results of the surgical pathology were compared with the imaging findings. The sensitivity, specificity, and accuracy of SE imaging were determined in terms of evaluating the "acute appendicitis". RESULTS Sonographic evaluation revealed acute appendicitis in 100 patients. Regarding the SE analysis, cases with appendicitis were classified into 3 groups as: mild (n=17), moderate (n=39), and severe (n=44). The pathological evaluation revealed 95 different stages of appendicitis and normal appendix in 5 cases: acute focal (n=10), acute suppurative (n=46), phlegmonous (n=27), and perforated (n=12), regarding the results of surgical pathology. Five patients with pathologically proven "normal" appendix were noted as "mild stage appendicitis" based on gray scale and SE analysis. In total, when gray-scale and SE results were compared with pathology results regardless of the stage of appendicitis, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy rates were 96%, 96%, 95%, 96.8%, and 96%, respectively. No statistically significant difference was detected between other groups (P<0.05). CONCLUSIONS In acute appendicitis, the use of SE imaging as a supportive method for the clinical approach can be useful in diagnosis, and its results are closely correlated with the histopathologic stage of appendix inflammation.

Esophageal intramural pseudodiverticulosis is a rare pathology whose etiology is unknown, but which is frequently associated with three highly prevalent entities: esophageal reflux disease, esophageal candidosis and alcoholic esophagitis. With conservative treatment the course of these pathologies is usually benign. However, some severe cases are resistant to conservative treatment and may require more aggressive management. We here present the case of patient suffering from a severe esophagitis complicated by chronic mediastinitis with life-threatening repercussions, requiring esophagectomy as treatment.

High-resolution esophageal manometry (HREM) has become a leading tool in the assessment of esophageal motor disorders, replacing conventional manometry. However, there is limited data about the contribution of HREM as compared with conventional manometry to the assessment of esophageal motor disorders in patients with non-cardiac chest pain (NCCP). The aim of the study was to compare the distribution of esophageal motor disorders in patients with NCCP using HREM as compared with conventional manometry and to determine if HREM improved diagnosis of these disorders. In this study, we included 300 consecutive patients with NCCP who underwent either HREM or conventional manometry over a period of 10 years. A total of 150 patients had conventional manometry and the other 150 patients HREM. The Chicago 3.0 classification and the Castell and Spechler classification were used to determine the esophageal motor disorder of NCCP patients undergoing HREM and conventional manometry, respectively. In both HREM and the conventional manometry groups, normal esophageal motility was the most frequent finding (47% and 36%; respectively, P = .054). Hypotensive lower esophageal sphincter was the most common motility disorder identified by conventional manometry (27.3%), while ineffective esophageal motility was the most common esophageal motor disorder identified by HREM (25.3%). There is a discrepancy in the type of esophageal motor disorders identified by HREM as compared with conventional manometry in NCCP patients. Hypotensive motility disorders are the most commonly diagnosed by both manometric techniques. © 2017 John Wiley & Sons Ltd.

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. © 2015 The Authors.

The role of esophageal dilation in patients with esophageal eosinophilia with dysphagia remains unknown. The practice of dilation is currently based on center preferences and expert opinion. The aim of this study is to determine if, and to what extent, dysphagia improves in response to initial esophageal dilation followed by standard medical therapies. We conducted a randomized, blinded, controlled trial evaluating adult patients with dysphagia and newly diagnosed esophageal eosinophilia from 2008 to 2013. Patients were randomized to dilation or no dilation at time of endoscopy and blinded to dilation status. Endoscopic features were graded as major and minor. Subsequent to randomization and endoscopy, all patients received fluticasone and dexlansoprazole for 2 months. The primary study outcome was reduction in overall dysphagia score, assessed at 30 and 60 days post-intervention. Patients with severe strictures (less than 7-mm esophageal diameter) were excluded from the study. Thirty-one patients were randomized and completed the protocol: 17 randomized to dilation and 14 to no dilation. Both groups were similar with regard to gender, age, eosinophil density, endoscopic score, and baseline dysphagia score. The population exhibited moderate to severe dysphagia and moderate esophageal stricturing at baseline. Overall, there was a significant (P < 0.001) but similar reduction in mean dysphagia score at 30 and 60 days post-randomization compared with baseline in both groups. No significant difference in dysphagia scores between treatment groups after 30 (P = 0.93) or 60 (P = 0.21) days post-intervention was observed. Esophageal dilation did not result in additional improvement in dysphagia score compared with treatment with proton pump inhibitor and fluticasone alone. In patients with symptomatic esophageal eosinophilia without severe stricture, dilation does not appear to be a necessary initial treatment strategy. © 2015 International Society for

Background and Aims The possible association between eosinophilic esophagitis (EoE) and celiac disease (CD) is controversial as prior results have been contradictory. We aimed to determine the relationship between EoE and CD among patients with concomitant esophageal and duodenal biopsies. Methods We conducted a cross-sectional study in a U.S. national pathology database, using data from January 2009 and June 2012. Our primary case definition was defined by the presence of esophageal eosinophilia with ≥ 15 eosinophils per high-power field. The crude and adjusted (for age and sex) odds of esophageal eosinophilia for patients with active CD were compared to those without CD. Sensitivity analyses were performed using more stringent case definitions and by estimating the associations between CD and reflux esophagitis, and CD and Barrett's esophagus (BE). Results Of 292,621 patients in the source population, 88,517 with both esophageal and duodenal biopsies were studied. 4,101 (4.6%) met criteria for EoE and 1,203 (1.4%) met criteria for CD. Odds of EoE were 26% higher in patients with CD than patients without CD (aOR: 1.26, 95% confidence interval [CI]: 0.98 – 1.60). The magnitude of association varied according to EoE case definition (Table 3), but all definitions showed a weak, positive association between the two conditions. There was no association between CD and reflux esophagitis (aOR 0.95, 95% CI: 0.85 – 1.07) or BE (aOR 0.89, 95% CI: 0.69 – 1.14) and CD. Conclusions There is a weak increase in EoE in patients with CD. This association strengthened with increasingly stringent definitions of EoE, and was not observed for other esophageal conditions. In patients with CD, concomitant EoE should be considered in the correct clinical setting. PMID:25724709

To prospectively assess the efficacy and safety of moderately hypofractionated conformal radiotherapy in patients with thoracic esophageal cancer. From Sept. 2002 to Oct. 2005, 150 eligible patients with T2-4N0-1M0 stage thoracic esophageal squamous cell cancers were enrolled to receive either conventional fractionated radiation (CFR) or moderately hypofractionated radiation (MHR) with a three- dimensional conformal radiation technique. Of the total, 74 received moderately hypofractionated radiation with total dose of 54-60 Gy/18-20 fractions for 3.5-4 weeks in the MHR arm, and 76 received conventional radiation with total dose of 60 Gy/30 fractions for 6 weeks in the CFR arm. Concurrent chemotherapy comprised of paclitaxel and cisplatin. Safety was evaluated, and local control and overall survival rates were calculated. Statistically significant differences between the CFR versus MHR arms were observed in local/regional failure rate (47.3% v 27.0%, P=0.034) and the percentage of patients with persistent local disease (26.3% v 10.8%, P=0.012). But 3 and 5-year overall survival rates (43.2%, 38.8% v 38.2%, 28.0%, respectively) were not different between the two arms (P=0.268). There were no significant differences in the incidences of grade 3 or higher acute toxicities (66.3% v 50.0%) and late complications rates (27.0% v 22.4%) between the MHR and CFR arms. Moderately hypofractionated, three-dimensional radiation treatment could improve the local control rate of esophageal cancer and potentially increase patient survival.

Evaluation of Esophageal Motor Function With High-resolution Manometry

PubMed Central

2013-01-01

For several decades esophageal manometry has been the test of choice to evaluate disorders of esophageal motor function. The recent introduction of high-resolution manometry for the study of esophageal motor function simplified performance of esophageal manometry, and revealed previously unidentified patterns of normal and abnormal esophageal motor function. Presentation of pressure data as color contour plots or esophageal pressure topography led to the development of new tools for analyzing and classifying esophageal motor patterns. The current standard and still developing approach to do this is the Chicago classification. While this methodical approach is improving our diagnosis of esophageal motor disorders, it currently does not address all motor abnormalities. We will explore the Chicago classification and disorders that it does not address. PMID:23875094

A fully coupled bolus-esophageal-gastric model for esophageal emptying based on the immersed boundary method

2016-11-01

In this work, we develop a fully coupled bolus-esophageal-gastric model to study esophageal emptying based on the immersed boundary method. The model includes an esophageal segment, an ellipsoid-shaped stomach, and a bolus. It can easily handle the passive and active function of the lower esophageal sphincter (LES). Two groups of case studies are presented. The first group is about the influence from tissue anisotropy. Simulation shows that the weaker (or more compliant) part suffers from a higher wall shear stress and higher pressure load when the bolus is filled in and emptied from the LES segment. This implies a degradation cycle in which a weaker tissue becomes much weaker due to an increased load, a possible pathway to the esophageal lower diverticulum. The second group is about bulge formation resulting from asymmetric anatomy and a compliant LES. In particular, we find a right bulge tends to develop for a compliant LES. The bulge is most pronounced with a highest stiffness of the gastric wall. This implies that the competition between the LES stiffness and gastric wall stiffness might be another factor related to the esophageal lower diverticulum.

Endoscopic Management of Benign Esophageal Strictures.

PubMed

Ravich, William J

2017-08-24

This paper presents the author's approach to esophageal dilation. It offers a tailored approach to the application of dilation to specific types of esophageal stenotic lesions. In patients with inflammatory stricture, recent studies confirm the importance of treating the underlying inflammatory condition in order to decrease the rate of recurrence. The paper reviews some of the novel techniques that have been suggested for the treatment of refractory benign esophageal strictures, including incisional therapy, stenting, or the injection steroids or antifibrotic agents. The endoscopist who treats esophageal strictures must be familiar with the tools of the dilation and how they are best applied to specific types of stenotic lesions. If inflammation is present, effective management requires treatment of the inflammatory process in addition to mechanical dilation of the stenotic lesion. Controlled trials of novel approaches to treatment of refractory benign esophageal strictures are limited and will be necessary to determine efficacy.

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. PMID:24868489

Dysmotility in Esophageal Atresia: Pathophysiology, Characterization, and Treatment

PubMed Central

Faure, Christophe; Righini Grunder, Franziska

2017-01-01

Esophageal dysmotility is almost universal after esophageal atresia (EA) repair and is mainly related to the developmental anomaly of the esophagus. Esophageal dysmotility is involved in the pathophysiology of numerous symptoms and comorbidities associated with EA such as gastroesophageal reflux disease, aspiration and respiratory complications, and symptoms of dysphagia and feeding disorders. High-resolution esophageal manometry (HREM) has facilitated the characterization of the dysmotility, but there is an incomplete correlation between symptoms and manometrical patterns. Impedance coupled to HREM should help to predict the clinical outcome and therefore personalize patient management. Nowadays, the management of esophageal dysmotility in patients with EA is essentially based on treatment of associated inflammation related to peptic or eosinophilic esophagitis. PMID:28620599

Changes in the expression of mucin genes in the esophageal mucosa associated with uncomplicated gastro-esophageal reflux disease have not been evaluated even though such changes could be associated with reflux-induced mucosal damage. We therefore sought to identify reflux-induced changes in mucin gene expression using a cell line and biopsies from the esophageal mucosa in patients with and without reflux. MUC-1, MUC-3, MUC-4, and MUC-5AC gene expressions were investigated in the HET-1A cell line following exposure to acid (pH 4) and/or bile (120 muM of a bile salt milieu), and in esophageal mucosal biopsies from controls, subjects with non-erosive gastro-esophageal reflux, and subjects with reflux associated with ulcerative esophagitis (erosive). The mucosal biopsies were also evaluated for IL-6 mRNA expression (inflammatory marker) and CK-14 mRNA expression (mucosal basal cell layer marker). Gene expression was determined using real-time reverse transcriptase-polymerase chain reaction analysis. In the cell line studies, there were differences in mRNA levels for all of the evaluated mucins following treatment with either acid or the acid and bile combination. In the studies which evaluated tissue specimens, IL-6 and CK-14 mRNA levels increased according to degree of reflux pathology. The expression of MUC-1 and MUC-4 in mucosa from patients with erosive reflux was lower than in subjects without reflux and in patients with non-erosive reflux, whereas the expression of MUC-3 and MUC-5AC was increased (although these differences did not reach significance at p < 0.05). When mRNA expression data for tissue samples from all groups were combined, significant correlations were identified between IL-6 vs. CK-14 and IL-6 vs. MUC-3, MUC-3 vs. CK-14 and MUC-3 vs. MUC-5AC, and for MUC-1 vs. MUC-5AC. The correlation between IL-6 and CK-14 was also significant within the control and non-erosive reflux groups. The correlation between IL-6 and MUC-3 was significant within the

Objectively Quantifying Radiation Esophagitis With Novel Computed Tomography–Based Metrics

DOE Office of Scientific and Technical Information (OSTI.GOV)

Niedzielski, Joshua S., E-mail: jsniedzielski@mdanderson.org; University of Texas Houston Graduate School of Biomedical Science, Houston, Texas; Yang, Jinzhong

Purpose: To study radiation-induced esophageal expansion as an objective measure of radiation esophagitis in patients with non-small cell lung cancer (NSCLC) treated with intensity modulated radiation therapy. Methods and Materials: Eighty-five patients had weekly intra-treatment CT imaging and esophagitis scoring according to Common Terminlogy Criteria for Adverse Events 4.0, (24 Grade 0, 45 Grade 2, and 16 Grade 3). Nineteen esophageal expansion metrics based on mean, maximum, spatial length, and volume of expansion were calculated as voxel-based relative volume change, using the Jacobian determinant from deformable image registration between the planning and weekly CTs. An anatomic variability correction method wasmore » validated and applied to these metrics to reduce uncertainty. An analysis of expansion metrics and radiation esophagitis grade was conducted using normal tissue complication probability from univariate logistic regression and Spearman rank for grade 2 and grade 3 esophagitis endpoints, as well as the timing of expansion and esophagitis grade. Metrics' performance in classifying esophagitis was tested with receiver operating characteristic analysis. Results: Expansion increased with esophagitis grade. Thirteen of 19 expansion metrics had receiver operating characteristic area under the curve values >0.80 for both grade 2 and grade 3 esophagitis endpoints, with the highest performance from maximum axial expansion (MaxExp1) and esophageal length with axial expansion ≥30% (LenExp30%) with area under the curve values of 0.93 and 0.91 for grade 2, 0.90 and 0.90 for grade 3 esophagitis, respectively. Conclusions: Esophageal expansion may be a suitable objective measure of esophagitis, particularly maximum axial esophageal expansion and esophageal length with axial expansion ≥30%, with 2.1 Jacobian value and 98.6 mm as the metric value for 50% probability of grade 3 esophagitis. The uncertainty in esophageal Jacobian calculations can be reduced

To study the relationship between esophageal motor functional disorder [decreased lower esophageal sphincter pressure (LESP)and ineffective motility (IEM)] and gastroesophageal reflux disease (GERD). Totally 89 patients with GERD were enrolled in this study. All of them underwent 24-hour pH monitoring with dual-channel probe and stationary esophageal manometry. In addition, 77 of these patients underwent upper endoscopy. IEM and LES, 10 mmHg were common disturbances in patients with GERD (54% and 48%, respectively). The number of the acid reflux events of distal esophagus and prevalence of moderate or severe erosive esophagitis (EE) were significantly higher in patients with low LESP and IEM than patients without low LESP ( P<0.05). The number of the acid reflux events in distal esophagus was significantly correlated with the severity of esophagitis, distal esophagus amplitude, and LESP, while no such correlation was found between IEM and degree of esophageal acid exposure or esophagitis. The pathophysiology of GERD is probably multifactorial. Lower LESP or IEM is not a independent pathophysiological factor for GERD. However,one single factor is insufficient to explain all the pathogenic mechanism of GERD.

Distal contractile integral (DCI) and esophagogastric junction contractile integral (EGJ-CI) are high-resolution manometry (HRM) software metrics assessing esophageal motor function in gastroesophageal reflux disease (GERD). Patients undergoing HRM and ambulatory pH monitoring off antisecretory therapy prospectively completed symptom questionnaires assessing symptom burden and a global symptom score (GSS) at baseline and after GERD therapy. DCI<450 mm Hg/cm/s in ≥5 swallows diagnosed ineffective esophageal motility (IEM); proportions of failed (DCI<100 mm Hg/cm/s) and weak (DCI 100-450 mm Hg/cm/s) sequences were separately assessed. EGJ-CI assessed vigor of the EGJ barrier. Univariate and multivariate analyses addressed performance of esophageal body and EGJ metrics in predicting abnormal esophageal reflux burden, and symptom outcome from antireflux therapy. Of 188 patients (55.2 ± 0.9 year, 64% F), 42.6% had low EGJ-CI, and 25.0% had IEM. While low EGJ-CI was associated with abnormal reflux burden (P = 0.003), IEM alone was not (P = 0.2). Increasing proportions of failed swallows predicted abnormal AET better than the current IEM definition. Combined low EGJ-CI and IEM segregated abnormal total and supine acid burden compared to patients with normal EGJ-CI and no IEM (P ≤ 0.007 for each comparison). Medical therapy and surgical antireflux therapy were similarly effective in improving symptom burden; surgery resulted in better outcomes with low EGJ-CI (P ≤ 0.04), especially with intact esophageal body motor function (P = 0.02). While abnormal EGJ and esophageal body metrics are collectively associated with elevated esophageal reflux burden, increasing proportions of failed swallows are better predictors of reflux burden and outcome compared to the current IEM definition. © 2017 John Wiley & Sons Ltd.

Reflux Hypersensitivity: A New Functional Esophageal Disorder

2017-01-01

Reflux hypersensitivity, recently introduced by Rome IV as a new functional esophageal disorder, is currently considered as the presence of typical heartburn symptoms in patients with normal upper endoscopy and esophageal biopsies, normal esophageal pH test and with evidence of a close correlation between patients’ heartburn and reflux events. Reflux hypersensitivity is very common and together with functional heartburn accounts for more than 90% of the heartburn patients who failed treatment with proton pump inhibitor twice daily. In addition, reflux hypersensitivity affects primarily young to middle aged women, commonly overlaps with another functional gastrointestinal disorders, and is often associated with some type of psychological comorbidity. Diagnosis is made by using endoscopy with esophageal biopsies, pH-impedance, and high-resolution esophageal manometry. Reflux hypersensitivity is primarily treated with esophageal neuromodulators, such as tricyclic anti-depressants and selective serotonin reuptake inhibitors among others. Surgical anti-reflux management may also play an important role in the treatment of reflux hypersensitivity. PMID:28992673

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.

Bleeding 'downhill' esophageal varices associated with benign superior vena cava obstruction: case report and literature review.

PubMed

Loudin, Michael; Anderson, Sharon; Schlansky, Barry

2016-10-24

Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices. Given the alternative pathophysiology of downhill varices, they require a unique approach to management. Variceal band ligation may be used to temporize acute variceal bleeding, and should be applied on the proximal end of the varix. Relief of the underlying SVC obstruction is the cornerstone of definitive treatment of downhill varices. A young woman with a benign superior vena cava stenosis due to a tunneled internal jugular vein dialysis catheter presented with hematemesis and melena. Urgent upper endoscopy revealed multiple 'downhill' esophageal varices with stigmata of recent hemorrhage. As there was no active bleeding, no endoscopic intervention was performed. CT angiography demonstrated stenosis of the SVC surrounding the distal tip of her indwelling hemodialysis catheter. The patient underwent balloon angioplasty of the stenotic SVC segment with resolution of her bleeding and clinical stabilization. Downhill esophageal varices are a distinct entity from the more common distal esophageal varices. Endoscopic therapies have a role in temporizing active variceal bleeding, but relief of the underlying SVC obstruction is the cornerstone of treatment and should be pursued as rapidly as possible. It is unknown why benign, as opposed to malignant, causes of SVC obstruction result in bleeding from downhill varices at such a high rate, despite being a less common etiology of SVC obstruction.

We studied 30 patients. 20 were males and 10 females. Mean age was 48 year old. Esophageal disease was not present neither gastro-esophageal reflux. Biopsy was taken between 24 hours and 25 days after nasogastric tube (NG) was put into place. Endoscopic findings were: hyperemic mucosa, submucosal hemorrhage, clots, erosions and ulcers near Esophago-gastric junction. Intraepithelial edema, vessel congestion, polymorphonuclear infiltration, fibrin thrombosis of submucosal vessels, ischemia, epithelial regeneration and ulcer were common histologic findings. All endoscopic and histologic alterations were related to the length of time of NG tube contact with the esophageal mucosa. We concluded that NG tube damages the esophageal mucosa by two mechanisms: a) Local irritation that favors b) gastric reflux by decreasing lower esophageal sphincter pressure.

Pathologies that involve the structure and/or function of the esophagus can be life-threatening. The esophagus is a complex organ comprising nonredundant tissue that does not have the ability to regenerate. Currently available interventions for esophageal pathology have limited success and are typically associated with significant morbidity. Hence, there is currently an unmet clinical need for effective methods of esophageal repair. The present article presents a review of esophageal disease along with the anatomic and functional consequences of each pathologic process, the shortcomings associated with currently available therapies, and the latest advancements in the field of regenerative medicine with respect to strategies for esophageal repair from benchtop to bedside.

Abnormalities in esophageal motor function underlie various symptoms in the pediatric population. Manometry remains an important tool for studying esophageal motor function, whereas its analyses have been conducted with considerable subjective interpretation. The usefulness of videomanometry with topographic analysis was examined in the current study. Videomanometry was conducted in 5 patients with primary gastroesophageal reflux disease (GERD), 4 with postoperative esophageal atresia (EA), 1 with congenital esophageal stenosis (CES), and 1 with diffuse esophageal spasms (DES). Digitized videofluoroscopic images were recorded synchronously with manometric digital data in a personal computer. Manometric analysis was conducted with a view of concurrent esophageal contour and bolus transit. Primary GERD patients showed esophageal flow proceeding into the stomach during peristaltic contractions recorded manometrically, whereas patients with EA/CES frequently showed impaired esophageal transit during defective esophageal peristaltic contractions. A characteristic corkscrew appearance and esophageal flow in a to-and-fro fashion were seen with high-amplitude synchronous esophageal contractions in a DES patient. The topographic analysis showed distinctive images characteristic of each pathological condition. Videomanometry is helpful in interpreting manometric data by analyzing concurrent fluoroscopic images. Topographic analyses provide characteristic images reflecting motor abnormalities in pediatric esophageal disease.

Three-dimensional computed tomography-based radiotherapy planning (3DCTP) is increasingly employed in the treatment of esophageal cancer. It is unknown whether a 3DCTP approach influences outcomes compared to two-dimensional planning (2DP). This study compares clinical outcomes for homogeneously treated patient cohorts stratified by planning modality. A retrospective chart review was conducted on patients with T3/4 and/or node-positive esophageal carcinoma treated at the Cleveland Clinic between July 1, 2003 and May 31, 2006 who were managed with an institutional regimen consisting of preoperative radiotherapy, whether 3DCTP or 2DP [30 Gy/20 fractions/1.5 Gy twice daily over 2 weeks], with concurrent cisplatin and 5-fluorouracil the first week. Following definitive resection, an identical postoperative course of concurrent chemoradiotherapy (CRT) was delivered. One hundred and forty-one patients completed preoperative CRT and were available for review. The median follow-up of living patients is 21.7 months. Fifty-five percent underwent 3DCTP and 45% had 2DP. The treatment groups were similar, with the exception of clinical stage group, with 2DP having more stage II and fewer stage III patients than 3DCTP (p = 0.02). 3DCTP plans had significantly smaller field sizes by area (p < 0.0001). Pathologic response, locoregional control, distant control, and overall survival were equivalent between the two planning modalities. Esophagitis was significantly less common with a 3D approach compared to 2D planning (49% vs. 71%, p = 0.0096), with other toxicities equivalent between the groups. 3DCTP reduces acute esophagitis in patients receiving multimodality therapy for esophageal cancer without compromising clinical outcomes.

The outcomes for patients with esophageal cancer (EC) underwent standard-dose radical radiotherapy were still disappointing. This phase II study investigated the feasibility, safety and efficacy of radiation dose escalation using simultaneous modulated accelerated radiotherapy (SMART) combined with chemotherapy in 60 EC patients. Radiotherapy consisted of 66Gy at 2.2 Gy/fraction to the gross tumor and 54Gy at 1.8 Gy/fraction to subclinical diseases simultaneously. Chemotherapy including cisplatin and 5fluorouracil were administered to all patients during and after radiotherapy. The data showed that the majority of patients (98.3%) completed the whole course of radiotherapy and concurrent chemotherapy. The most common ≥ grade 3 acute toxicities were neutropenia (16.7%), followed by esophagitis (6.7%) and thrombopenia (5.0%). With a median follow-up of 24 months (5-38) for all patients and 30 months (18-38) for those still alive, 11 patients (18.3%) developed ≥ Grade 3 late toxicities and 2 (3.3%) of them died subsequently due to esophageal hemorrhage. The 1- and 2-year local-regional control, distant metastasis-free survival, disease-free survival and overall survival rates were 87.6% and 78.6%, 86.0% and 80.5%, 75.6% and 64.4%, 86.7% and 72.7%, respectively. SMART combined with concurrent chemotherapy is feasible in EC patients with tolerable acute toxicities. They showed a trend of significant improvements in local-regional control and overall survival. Further follow-up is needed to evaluate the late toxicities.

Esophageal transit of a small volume of watery liquid has been observed scintigraphically in 200 studies performed on patients aged between 6 days and 16 years. 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 possible association between eosinophilic esophagitis (EoE) and celiac disease is controversial because prior results have been contradictory. We aimed to determine the relationship between EoE and celiac disease among patients with concomitant esophageal and duodenal biopsies. We conducted a cross-sectional study in a U.S. national pathology database by using data from January 2009 through June 2012. Our primary case definition was defined by the presence of esophageal eosinophilia with ≥15 eosinophils per high-power field. The crude and adjusted (for age and sex) odds of esophageal eosinophilia for patients with active celiac disease were compared with those without celiac disease. Sensitivity analyses were performed by using more stringent case definitions and by estimating the associations between celiac disease and reflux esophagitis and celiac disease and Barrett's esophagus. Of 292,621 patients in the source population, 88,517 with both esophageal and duodenal biopsies were studied. Four thousand one hundred one (4.6%) met criteria for EoE, and 1203 (1.4%) met criteria for celiac disease. Odds of EoE were 26% higher in patients with celiac disease than in patients without celiac disease (adjusted odds ratio [aOR], 1.26; 95% confidence interval [CI], 0.98-1.60). The magnitude of association varied according to EoE case definition, but all definitions showed a weak positive association between the 2 conditions. There was no association between celiac disease and reflux esophagitis (aOR, 0.95; 95% CI, 0.85-1.07) or Barrett's esophagus (aOR, 0.89; 95% CI, 0.69-1.14) and celiac disease. There is a weak increase in EoE in patients with celiac disease. This association strengthened with increasingly stringent definitions of EoE and was not observed for other esophageal conditions. In patients with celiac disease, concomitant EoE should be considered in the correct clinical setting. Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights

When esophageal cancer infiltrates the respiratory tract and forms a fistula, a patient's quality of life falls remarkably. Abstinence from oral feeding is necessary to prevent respiratory complications including pneumonia. Surgery is sometimes necessary to maintain quality of life. The aim of this study was to examine clinical outcomes of esophageal cancer complicated by tracheobronchial fistula. Twelve patients who underwent esophageal bypass between 2006 and 2011 in our hospital were studied. Patient characteristics, therapeutic course, outcome, and operation type were compared. Six patients among 8 who could not tolerate oral feeding could do so after bypass surgery. Ten patients were able to enjoy oral intake up until the last few days of life. Three patients survived for more than 10 months. In spite of undergoing an operation, 1 patient survived for only 2 months and another for 4 months. The only complication was postoperative delirium in 1 patient. While surgical bypass is more invasive than procedures such as endoscopic stenting, we had few complications after operative intervention and were able to maintain quality of life in our patients. This bypass procedure is a treatment option for patients with tracheobronchial fistula from advanced esophageal cancer. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Transient lower esophageal sphincter (LES) relaxation (TLESR) is defined as LES relaxation without a swallow. TLESRs are observed in both of the normal individuals and the patients with gastroesophageal reflux disorder (GERD). However, TLESR is widely considered as the major mechanism of the GERD. The new equipments such as high resolution manometry and impedance pH study is helped to understand of TLESR and the related esophageal motor activities. The strong longitudinal muscle contraction was observed during development of TLESR. Most of TLESRs are terminated by TLESR related motor events such as primary peristalsis and secondary contractions. The majority of TLESRs are associated with gastroesophageal reflux. Upper esophageal sphincter (UES) contraction is mainly associated with liquid reflux during recumbent position and UES relaxation predominantly related with air reflux during upright position. The frequency of TLESR in GERD patients seems to be not different compared to normal individuals, but the refluxate of GERD patients tend to be more acidic during TLESR.

Esophageal stenting is a popular of treatment of esophageal strictures in adults. It has also been described for children with benign strictures who did not respond to standard dilatation therapy. The aim of the study was to evaluate weather esophageal stents could be used safely and effectively in the treatment of benign esophageal strictures in children. From 1993 to 2005 stenting therapy was performed in 12 children with complicated esophageal strictures. Etiologies of the strictures were caustic burns in 9 patients, postoperative strictures due to complicated esophageal atresia in 2 patients and iatrogenic esophageal injury in 1 patient. Esophageal silicon tubi, covered retrievable expandable nitinol and plastic stents were placed endoscopically. The clinical course and the long term follow up were evaluated retrospectively The stents and tubi were placed in all patients without complications and were later removed successfully. 6 patients were treated with a self expanding plastic stent. The plastic stents showed a distinct tendency to migrate but in 5/6 patients esophageal stricture was treated successfully. 3 patients were treated by a covered self expanding nitinol stent. No migration occurred. One patient was asymptomatic after therapy, one required further dilatation therapy and the third had esophageal resection. 3 patients were treated by esophageal tubi. 2 patients required surgery in the follow up, one patient is asymptomatic. The use of stenting devices in children to treat benign esophageal strictures is safe and efficient. The self expanding plastic stents had the best long term results but required high compliance of parents and children due to the tendency of stent migration. Self expanding nitinol stents are more traumatic at the extraction procedure and are useful in patients with low compliance. Recurrence of strictures occurred most often after esophageal tubi possibly due to the lack of radial expansion.

Endoscopic dilation (ED) is used for the treatment of benign strictures caused by reflux esophagitis or anastomotic stenosis after esophagectomy. Esophageal stenosis is a major complication after endoscopic submucosal dissection (ESD) of large superficial esophageal cancer, but little is known regarding the incidence of complications of ED for stenosis caused by esophageal ESD. This was a retrospective study conducted at a single institution. From September 2002 to December 2012, a total of 1,337 ED procedures were performed for stenosis after esophageal ESD in 121 patients. The incidence of complications of ED and related clinical characteristics were analyzed. The incidence of bleeding was 0.8 % (1/121) per patient and 0.07 % (1/1,337) per procedure. The incidence of perforation was 4.1 % (5/121) per patient and 0.37 % (5/1,337) per procedure. Perforation occurred at a median of third time of ED procedures (range 2-9 procedures) and at a median of 18 days (range 8-29 days) after ESD. There were no significant characteristics correlated to perforation, such as location, circumferential extent, or diameter of mucosal defect after ESD. The total number of ED procedures was significantly larger among perforation cases (37, range 6-57) compared with those without perforation (7, range 1-70) (p = 0.01), and the treatment duration tended to be longer (190 vs. 69 days, respectively). The incidence of bleeding caused by ED for esophageal stenosis after ESD was very low. Relevant risk of perforation should be considered for patients requiring multiple ED procedures.

Self-expandable esophageal stents are being commonly used for palliative treatment in advanced esophageal cancer patients to relieve dysphagia, prevent tracheoesophageal fistula, and facilitate symptomatic betterment. The modern covered stents reduce the ingrowth of the tumor but have seen an increase in the incidence of stent migrations. We report a rather complicated presentation of an esophageal stent for esophageal dilatation and a challenging management of a difficult tracheostomy.

Luminal esophageal temperature (LET) monitoring is one strategy to minimize esophageal injury during atrial fibrillation ablation procedures. However, esophageal ulceration and fistulas have been reported despite adequate LET monitoring. The objective of this study was to assess a novel approach to LET monitoring with a deflectable LET probe on the rate of esophageal injury in patients undergoing atrial fibrillation ablation. Forty-five consecutive patients undergoing an atrial fibrillation ablation procedure followed by esophageal endoscopy were included in this prospective observational pilot study. LET monitoring was performed with a 7F deflectable ablation catheter that was positioned as close as possible to the site of left atrial ablation using the deflectable component of the catheter guided by visualization of its position on intracardiac echocardiography. Ablation in the posterior left atrial was limited to 25 W and terminated when the LET increased 2°C from baseline. Endoscopy was performed 1 to 2 days after the procedure. All patients had at least 1 LET elevation >2°C necessitating cessation of ablation. Deflection of the LET probe was needed to accurately measure LET in 5% of patients when ablating near the left pulmonary veins, whereas deflection of the LET probe was necessary in 88% of patients when ablating near the right pulmonary veins. The average maximum increase in LET was 2.5±1.5°C. No patients had esophageal thermal injury on follow-up endoscopy. A strategy of optimal LET probe placement using a deflectable LET probe and intracardiac echocardiography guidance, combined with cessation of radiofrequency ablation with a 2°C rise in LET, may reduce esophageal thermal injury during left atrial ablation procedures.

Dysphagia is a clinically relevant symptom in patients with Parkinson's disease (PD) leading to pronounced reduction in quality of life and other severe complications. Parkinson's disease-related dysphagia may affect the oral and pharyngeal, as well as the esophageal phase of swallowing. To examine the nature and extend of esophageal dysphagia in different stages of PD and their relation to oropharyngeal dysfunction, we examined 65 PD patients (mean age 66.3±9.7 years, mean disease duration 7.9±5.8 years, mean Hoehn & Yahr [H&Y] stage 2.89±0.91) and divided into three groups (early [H&Y I+II; n=21], intermediate [H&Y III; n=25], and advanced stadium [H&Y IV+V; n=19]), using esophageal high-resolution manometry (HRM) to detect esophageal motor disorders. Oropharyngeal impairment was assessed using fiberoptic endoscopic evaluation of swallowing. Major esophageal motor disorders were detected in nearly one third of the PD patients. Minor impairment of the esophageal body was present in 95% of participants and throughout all disease stages with pathological findings especially in peristalsis and intrabolus pressure (IBP). The IBP was found to significantly increase in the advanced stadium. Although dysfunction of the upper and lower esophageal sphincters was observed in individual patients, alterations in these esophageal segments revealed no statistical significance compared with normative data. No clear association was found between the occurrence of oropharyngeal dysphagia and esophageal impairment. Esophageal body impairment in PD is a frequent phenomenon during all disease stages, which possibly reflects α-synucleinopathy in the enteric nervous system. © 2016 John Wiley & Sons Ltd.

There is no clear consensus concerning the best endoscopic treatment of benign refractory esophageal strictures due to caustic ingestion. Different procedures are currently used: frequent multiple dilations, retrievable self-expanding stent, nasogastric intubation and surgery. We describe a new technique to fix a suspended esophageal silicone prosthesis to the neck in benign esophageal strictures; this permits us to avoid the frequent risk of migration of the expandable metallic or plastic stents. Under general anesthesia a rigid esophagoscope was placed in the patient's hypopharynx. Using transillumination from the optical device, the patient's neck was pierced with a needle. A n.0 monofilament surgical wire was pushed into the needle, grasped by a standard foreign body forceps through the esophagoscope and pulled out of the mouth (as in percutaneous endoscopic gastrostomy procedure). After tying the proximal end of the silicone prosthesis with the wire, it was placed through the strictures under endoscopic view. This procedure was successfully utilized in four patients suffering from benign refractory esophageal strictures due to caustic ingestion. The prosthesis and its suspension from the neck were well-tolerated until removal (mean duration 4 months). A postoperative transitory myositis was diagnosed in only one patient. One of the most frequent complications of esophageal prostheses in refractory esophageal strictures due to caustic ingestion is distal migration. Different solutions were proposed. For example the suspension of a wire coming from the nose and then fixed behind the ear. This solution is not considered optimal because of patient complaints and moreover the aesthetic aspect is compromised. The procedure we utilized in four patients utilized the setting of a silicone tube hanging from the neck in a way similar to that of endoscopic pharyngostomy. This solution is a valid alternative both for quality of life and for functional results.

Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have recently been accepted as less invasive methods for treating patients with early esophageal cancers such as squamous cell carcinoma and dysplasia of Barrett’s esophagus. However, the large defects in the esophageal mucosa often cause severe esophageal strictures, which dramatically reduce the patient’s quality of life. Although preventive endoscopic balloon dilatation can reduce dysphagia and the frequency of dilatation, other approaches are necessary to prevent esophageal strictures after ESD. This review describes several strategies for preventing esophageal strictures after ESD, with a particular focus on anti-inflammatory and tissue engineering approaches. The local injection of triamcinolone acetonide and other systemic steroid therapies are frequently used to prevent esophageal strictures after ESD. Tissue engineering approaches for preventing esophageal strictures have recently been applied in basic research studies. Scaffolds with temporary stents have been applied in five cases, and this technique has been shown to be safe and is anticipated to prevent esophageal strictures. Fabricated autologous oral mucosal epithelial cell sheets to cover the defective mucosa similarly to how commercially available skin products fabricated from epidermal cells are used for skin defects or in cases of intractable ulcers. Fabricated autologous oral-mucosal-epithelial cell sheets have already been shown to be safe. PMID:25386058

Chemoradiotherapy for esophageal squamous cell cancer.

PubMed

Sasaki, Yusuke; Kato, Ken

2016-09-01

Chemoradiotherapy has been clinically indicated for patients with resectable esophageal squamous cell carcinoma who refuse surgical resection and in locally advanced unresectable esophageal squamous cell carcinoma patients. Concurrent chemoradiotherapy prolongs survival than radiation therapy alone when given as definitive treatment. Therefore, chemoradiotherapy is recognized as the standard non-invasive treatment for patients with localized esophageal cancer who opt for non-surgical treatment. JCOG9906 showed promising outcomes for stage II/III ESCC patients. But there are some problems about chemoradiotherapy for esophageal squamous cell carcinoma. Late toxicities are sometimes lethal for patients who achieved complete response even after years. Salvage treatment for residual or recurrent disease is unestablished. Modified Radiation Therapy Oncology Group regimen at the dose of 50.4 Gy reduced late toxicities without reducing efficacy. Optimal timings and procedure of salvage surgery and endoscopic therapy is evaluated in JCOG0909. Strategy including salvage therapy after chemoradiotherapy should be considered at the time of starting the treatment. Targeted therapy has not shown adding effect for chemoradiotherapy for esophageal squamous cell carcinoma yet. New agents, such as immune checkpoint inhibitors, are expected to show synergistic effect with chemoradiotherapy for esophageal squamous cell carcinoma. Further investigation is needed. © The Author 2016. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

Chemoprevention of esophageal squamous cell carcinoma

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, andmore » 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.« less

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.

2018-05-27

Esophageal achalasia is a primary esophageal motility disorder of unknown origin, characterized by lack of peristalsis and by incomplete or absent relaxation of the lower esophageal sphincter in response to swallowing. The goal of treatment is to eliminate the functional obstruction at the level of the gastroesophageal junction Areas covered: This comprehensive review will evaluate the current literature, illustrating the diagnostic evaluation and providing an evidence-based treatment algorithm for this disease Expert commentary: Today we have three very effective therapeutic modalities to treat patients with achalasia - pneumatic dilatation, per-oral endoscopic myotomy and laparoscopic Heller myotomy with fundoplication. Treatment should be tailored to the individual patient, in centers where a multidisciplinary approach is available. Esophageal resection should be considered as a last resort for patients who have failed prior therapeutic attempts.

Studies of the pressure response of the upper esophageal sphincter (UES) to simulated or spontaneous gastroesophageal reflux have shown conflicting results. These discrepancies could result from uncontrolled influence of variables such as posture, volume, and velocity of distension. We characterized in humans the effects of these variables on UES pressure response to esophageal distension. We studied 12 healthy volunteers (average, 27 ± 5 years old; 6 male) using concurrent esophageal infusion and high-resolution manometry to determine UES, lower esophageal sphincter, and intraesophageal pressure values. Reflux events were simulated by distal esophageal injections of room temperature air and water (5, 10, 20, and 50 mL) in individuals in 3 positions (upright, supine, and semisupine). Frequencies of various UES responses were compared using χ(2) analysis. Multinomial logistical regression analysis was used to identify factors that determine the UES response. UES contraction and relaxation were the overriding responses to esophageal water and air distension, respectively, in a volume-dependent fashion (P < .001). Water-induced UES contraction and air-induced UES relaxation were the predominant responses among individuals in supine and upright positions, respectively (P < .001). The prevalence of their respective predominant response significantly decreased in the opposite position. Proximal esophageal dp/dt significantly and independently differentiated the UES response to infusion with water or air. The UES response to esophageal distension is affected by combined effects of posture (spatial orientation of the esophagus), physical properties, and volume of refluxate, as well as the magnitude and rate of increase in intraesophageal pressure. The UES response to esophageal distension can be predicted using a model that incorporates these factors. Copyright © 2012 AGA Institute. Published by Elsevier Inc. All rights reserved.

Hiccups are actions consisting of sudden contractions of the diaphragm and intercostals followed by a sudden inspiration and transient closure of the vocal cords. They are generally short lived and benign; however, in extreme and rare cases, such as esophageal carcinoma, they can become persistent or intractable, up to and involving significant pain, dramatically impacting the patient's quality of life. This case involves a 60-year-old man with a known history of squamous cell carcinoma of the esophagus. He was considered to have high surgical risk, and therefore he received palliative care through the use of fully covered metallic esophageal self-expandable stents due to a spontaneous perforated esophagus, after which he developed intractable hiccups and associated mediastinal pain. Conservative treatment, including baclofen, chlorpromazine, metoclopramide, and omeprazole, provided no relief for his symptoms. The patient was referred to pain management from gastroenterology for consultation on pain control. He ultimately received an ultrasound-guided left phrenic nerve block with bupivacaine and depomedrol, and 3 days later underwent the identical procedure on the right phrenic nerve. This led to complete resolution of his hiccups and associated mediastinal pain. At follow-up, 2 and 4 weeks after the left phrenic nerve block, the patient was found to maintain complete alleviation of the hiccups. Esophageal dilatation and/or phrenic or vagal afferent fiber irritation can be suspected in cases of intractable hiccups secondary to esophageal stenting. Regional anesthesia of the phrenic nerve through ultrasound guidance offers a long-term therapeutic option for intractable hiccups and associated mediastinal pain in selected patients with esophageal carcinoma after stent placement.

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.

The cause of idiopathic pulmonary fibrosis (IPF) remains unknown, yet gastro-esophageal reflux disease (GERD) is highly prevalent in this population. GERD prevalence was studied, and esophageal function tests (EFT) were assessed in Chinese IPF patients. We prospectively studied 69 IPF patients who undertook both stationary High Resolution esophageal Manometry/Impedance (HRiM) and 24-hour esophageal Multi-Channel Intraluminal Impedance with pH Recordings (MII/pH). Patients were divided into GERD+ and GERD- groups according to pH results. Controls were HRiM treated healthy volunteers, and patients without IPF received HRiM and MII/pH diagnosed with GERD. 69 IPF patients, 62 healthy volunteers, and 88 IPF negative GERD patients were selected. GERD prevalence in IPF was 43/69 (62.3%), and 58.1% of patients presented with at least one typical symptom. Symptoms had a sensitivity of 58.1%, a specificity of 61.6%, a positive predictive value of 71.4% and a negative predictive of 47.1%. Compared with healthy volunteers, IPF patients had significantly decreased lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure (UESP) and complete bolus transit rate (CBTR). By contrast, IPF patients had increased total bolus transit time and prevalence of weak peristalsis. MII/pH showed that one third of IPF patients had abnormal distal and proximal reflux, especially non-acid reflux. Compared with GERD patients without IPF, GERD patients with IPF had significantly decreased CBTR and UESP with increased bolus exposure time. GERD prevalence in IPF was high, but symptoms alone were an unreliable predictor of reflux. IPF patients had lower LESP and UESP, impaired esophageal peristalsis and bolus clearance function with more proximal reflux events.

Endoscopic diagnosis of esophageal achalasia lacking typical endoscopic features can be extremely difficult. The aim of this study was to identify simple and reliable early indicator of esophageal achalasia. This single-center retrospective study included 56 cases of esophageal achalasia without previous treatment. As a control, 60 non-achalasia subjects including reflux esophagitis and superficial esophageal cancer were also included in this study. Endoscopic findings were evaluated according to Descriptive Rules for Achalasia of the Esophagus as follows: (1) esophageal dilatation, (2) abnormal retention of liquid and/or food, (3) whitish change of the mucosal surface, (4) functional stenosis of the esophago-gastric junction, and (5) abnormal contraction. Additionally, the presence of the longitudinal superficial wrinkles of esophageal mucosa, "pinstripe pattern (PSP)" was evaluated endoscopically. Then, inter-observer diagnostic agreement was assessed for each finding. The prevalence rates of the above-mentioned findings (1-5) were 41.1%, 41.1%, 16.1%, 94.6%, and 43.9%, respectively. PSP was observed in 60.7% of achalasia, while none of the control showed positivity for PSP. PSP was observed in 26 (62.5%) of 35 cases with shorter history < 10 years, which usually lacks typical findings such as severe esophageal dilation and tortuosity. Inter-observer agreement level was substantial for food/liquid remnant (k = 0.6861) and PSP (k = 0.6098), and was fair for abnormal contraction and white change. The accuracy, sensitivity, and specificity for achalasia were 83.8%, 64.7%, and 100%, respectively. "Pinstripe pattern" could be a reliable indicator for early discrimination of primary esophageal achalasia.

Esophageal Achalasia: Pathophysiology, Clinical Presentation, and Diagnostic Evaluation.

PubMed

Schlottmann, Francisco; Neto, Rafael M L; Herbella, Fernando A M; Patti, Marco G

2018-04-01

Esophageal achalasia is a primary esophageal motility disorder characterized by the absence of esophageal peristalsis and failure of the lower esophageal sphincter to relax in response to swallowing. These abnormalities lead to impaired emptying of food from the esophagus into the stomach with resulting food stasis. Most patients experience severe dysphagia, and regurgitation can lead to aspiration and respiratory problems. Consequently, the quality of life of patients affected by achalasia is severely impacted. A thorough evaluation with upper endoscopy, barium swallow, and esophageal manometry is mandatory to establish the diagnosis and plan the optimal treatment. In selected patients, an ambulatory pH monitoring is recommended to distinguish between gastroesophageal reflux disease and achalasia.

Congenital esophageal stenosis (CES) is a rare clinical condition but is frequently associated with esophageal atresia (EA). The aim of this study is to report the diagnosis, management, and outcome of CES associated with EA. Medical charts of CES-EA patients from Lille University Hospital, Sainte-Justine Hospital, and Montreal Children's Hospital were retrospectively reviewed. Seventeen patients (13 boys) were included. The incidence of CES in patients with EA was 3.6%. Fifteen patients had a type C EA, one had a type A EA, and one had an isolated tracheoesophageal fistula. Seven patients had associated additional malformations. The mean age at diagnosis was 11.6 months. All but two patients had non-specific symptoms such as regurgitations or dysphagia. One CES was diagnosed at the time of surgical repair of EA. In 12 patients, CES was suspected based on abnormal barium swallow. In the remaining four, the diagnostic was confirmed by esophagoscopy. Eleven patients were treated by dilation only (1-3 dilations/patient). Six patients underwent surgery (resection and anastomosis) because of failure of attempted dilations (1-7 dilations/patient). Esophageal perforation was encountered in three patients (18%). Three patients had histologically proven tracheobronchial remnants. CES associated with EA is frequent. A high index of suspicion for CES must remain in the presence of EA. Dilatation may be effective to treat some of them, but perforation is frequent. Surgery may be required, especially in CES secondary to ectopic tracheobronchial remnants. © 2014 International Society for Diseases of the Esophagus.

The role of epithelial cells in eosinophilic esophagitis (EoE) is not well understood. In this study, our aim was to isolate, culture, and expand esophageal epithelial cells obtained from patients with or without EoE and characterize differences observed over time in culture. Biopsies were obtained at the time of endoscopy from children with EoE or suspected to have EoE. We established patient-derived esophageal epithelial cell (PDEEC) lines utilizing conditional reprogramming methods. We determined integrin profiles, gene expression, MHC class II expression, and reactivity to antigen stimulation. The PDEECs were found to maintain their phenotype over several passages. There were differences in integrin profiles and gene expression levels in EoE-Active compared to normal controls and EoE-Remission patients. Once stimulated with antigens, PDEECs express MHC class II molecules on their surface, and when co-cultured with autologous T-cells, there is increased IL-6 and TNF-α secretion in EoE-Active patients vs. controls. We are able to isolate, culture, and expand esophageal epithelial cells from pediatric patients with and without EoE. Once stimulated with antigens, these cells express MHC class II molecules and behave as non-professional antigen-presenting cells. This method will help us in developing an ex vivo, individualized, patient-specific model for diagnostic testing for causative antigens.

Dysphagia in Children with Esophageal Atresia: Current Diagnostic Options.

Rayyan, Maissa; Allegaert, Karel; Omari, Taher; Rommel, Nathalie

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. Georg Thieme Verlag KG Stuttgart · New York.

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.

The objective of this study is to determine the prevalence of esophageal disorders (ED) associated with recurrent chest pain (RCP) and the utility of esophageal functional tests (EFT) in the study of these patients. The cross-sectional study was conducted at Hospital Clínico de La Frontera, Chile. One hundred and twenty-three patients with RCP were studied using esophageal manometry, edrophonium stimulation and 24-h pH monitoring. The performance of EFT was considered acceptable when they were capable of finding ED. To state the probability that RCP had an esophageal origin, patients were classified according to whether their pain had a probable, possible or unlikely esophageal origin. The prevalence of ED was determined according to diagnoses obtained after applying EFT and a multivariate analysis was performed to examine the association between the esophageal origin of RCP and ED. Rates of correct diagnosis of 65.9%, 56.9% and 31.7% was verified for 24-h pH monitoring, esophageal manometry and edrophonium stimulation, respectively. In 38.2% of patients with RCP, the pain was probably of esophageal origin, in 42.3% there was a possible esophageal origin and in 19.5% an unlikely esophageal origin. A 44.7% prevalence of GERD, 26.8% of GERD with secondary esophageal motor dysfunction and 8.9% of pure esophageal motor dysfunction were verified. The multivariate analysis allowed us to verify the association between the probability of esophageal origin of RCP, the variables RCP duration, esophagitis and dysphagia coexistence (P= 0.037, P= 0.030 and P= 0.024, respectively), and a statistically significant association between ED and dysphagia coexistence (P= 0.028). A high prevalence of ED was identified in patients with RCP.

From reflux esophagitis to Barrett’s esophagus and esophageal adenocarcinoma

PubMed Central

Wang, Rui-Hua

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 goal of the study was to evaluate the prevalence and risk factors of esophageal motor disorders in systemic sclerosis. In 183 consecutive cases of scleroderma, as diagnosed by American College of Rheumatology criteria (1980). Patients' mean age was 40.6+/-13.3 years, the gender ratio was 0.13 and the average duration of disease was 6.8+/-7.5 years. A localized, cutaneous form was observed in 148 patients (81%) and a diffuse form in 35 (19%). All patients underwent upper gastrointestinal endoscopy and standard esophageal manometry. Esophageal symptoms and reflux esophagitis were found in 108 (59%) and 68 (37%) of patients, respectively. Esophageal motor disorders were present in 148 patients (81%), and were associated with a hypotensive lower esophageal sphincter in 114 (62%). The presence of these motor abnormalities was not related to age, gender, skin extension or duration of disease. Esophageal motor disorders were present in almost all patients with esophageal symptoms or esophagitis, and were also found in 48 (64%) of the asymptomatic patients. Esophageal motor disorders are frequently seen in scleroderma, especially in cases with clinical symptoms, but are not associated with a specific form of the disease.

The pathophysiology of esophageal epiphrenic diverticula is still uncertain even though a concomitant motility disorder is found in the majority of patients in different series. High resolution manometry may allow detection of motor abnormalities in a higher number of patients with esophageal epiphrenic diverticula compared with conventional manometry. This study aims to evaluate the high resolution manometry findings in patients with esophageal epiphrenic diverticula. Nine individuals (mean age 63 ± 10 years, 4 females) with esophageal epiphrenic diverticula underwent high resolution manometry. A single diverticulum was observed in eight patients and multiple diverticula in one. Visual analysis of conventional tracings and color pressure plots for identification of segmental abnormalities was performed by two researchers experienced in high resolution manometry. Upper esophageal sphincter was normal in all patients. Esophageal body was abnormal in eight patients; lower esophageal sphincter was abnormal in seven patients. Named esophageal motility disorders were found in seven patients: achalasia in six, diffuse esophageal spasm in one. In one patient, a segmental hypercontractile zone was noticed with pressure of 196 mm Hg. High resolution manometry demonstrated motor abnormalities in all patients with esophageal epiphrenic diverticula.

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

The study aim was to compare the incidence of esophageal injuries between different temperature probes in the monitoring of esophageal temperature during atrial fibrillation (AF) ablation. One hundred patients with drug-resistant AF were prospectively and randomly assigned into two groups according to the esophageal temperature probe used: the multi-thermocouple probe group (n = 50) and the deflectable temperature probe group (n = 50). Extensive pulmonary vein (PV) isolation was performed with a 3.5-mm open irrigated tip ablation catheter by using a radiofrequency (RF) power of 25-30 W. In both groups, the esophageal temperature thermocouple was placed on the area of the esophagus adjacent to the ablation site. When the esophageal temperature reached 42 °C, the RF energy delivery was stopped. Esophageal endoscopy was performed 1 day after the catheter ablation. No differences existed between the two groups in terms of clinical background and various parameters related to the catheter ablation, including RF delivery time and number of RF deliveries at an esophageal temperature of >42 °C. Esophageal lesions, such as esophagitis and esophageal ulcers, occurred in 10/50 (20 %) and 15/50 (30 %) patients in the multi-thermocouple and deflectable temperature probe groups, respectively (P = 0.25). Most lesions were mild to moderate injuries, and all were cured using conservative treatment. The incidence of esophageal injury was almost equal between the multi-thermocouple temperature probe and the deflectable temperature probe during esophageal temperature monitoring. Most of the esophageal lesions that developed during esophageal temperature monitoring were mild to moderate and reversible.

Esophageal manifestations of celiac disease.

PubMed

Lucendo, A J

2011-09-01

Celiac disease (CD) may often be associated with various motor disorders affecting the different segments of the digestive tract, including the esophagus. Although it has not been universally reported, some available evidences indicate that pediatric and adult celiac patients could manifest a higher frequency of esophagitis and gastroesophageal reflux disease-related symptoms compared to nonceliac patients. In addition, several published studies have consistently shown the efficacy of a gluten-free diet in rapidly controlling esophageal symptoms and in preventing their recurrence. Since the participation of gluten in the esophageal symptoms of CD seems clear, its intimate mechanisms have yet to be elucidated, and several hypothesis have been proposed, including the specific immune alterations characterizing CD, the reduction in nutrient absorption determining the arrival of intact gluten to distal gastrointestinal segments, and various dysregulations in the function of gastrointestinal hormones and peptides. Recent studies have suggested the existence of a possible relationship between CD and eosinophilic esophagitis, which should be more deeply investigated. © 2011 Copyright the Author.

Assessing esophageal dysphagia.

PubMed

Kruger, Danielle

2014-05-01

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.

Radiation techniques for esophageal cancer.

PubMed

Zhang, Minsi; Wu, Abraham J

2017-10-01

Radiotherapy plays a crucial role in the curative management of localized esophageal cancer, both as definitive and preoperative therapy. For definitive therapy, the standard radiation dose is 50.4 Gy in 28 fractions and should be delivered with concurrent chemotherapy. Chemoradiotherapy also has a wellestablished benefit in the preoperative setting, as established in the CROSS randomized trial. Radiation fields are typically generous, to account for subclinical extension of disease along the esophagus and to regional nodes. Three-dimensional conformal radiation is the current standard technique for esophageal cancer, though intensity-modulated radiation therapy is increasingly utilized and may improve the outcomes of esophageal radiotherapy by reducing radiation dose to critical normal tissues.

Lymphocytic esophagitis: Report of three cases and review of the literature

2016-01-01

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

Esophageal and gastric cancers are both common and deadly. Patients present most often after disease progression and survival is therefore poor. Due to demographic variability and recent changes in disease incidence, much emphasis has been placed on studying risk factors for both esophageal and gastric cancers. However, with increasing understanding of these diseases, low survival rates persist and continued intensive studies are necessary to optimize treatment plans. This review article discusses updates in the evolving epidemiology, clinical presentation, risk factors, and diagnostic and treatment modalities of esophageal and gastric cancers.

Esophageal cancer is one of the most fatal diseases worldwide mainly because of its rapid progression and poor prognosis. Although the incidence of esophageal adenocarcinoma has markedly risen in North America and Europe in the past several decades, esophageal squamous cell carcinoma is still the predominant subtype of esophageal cancer, especially in China. It accounts for more than 90% of all esophageal squamous cell carcinoma cases in China. Geographical differentiation is one of the most distinctive characteristics of esophageal cancer. The progression, risk factors, and prognosis of these two subtypes of esophageal cancer differ. This study reviews the epidemiology, etiology, and prevention of esophageal squamous cell carcinoma in China, thereby providing systematic references for policy-makers who will decide on issues of esophageal cancer prevention and control.

Nutritional status and dietary intake are increasingly recognized as essential areas in esophageal cancer management. Nutritional management of esophageal cancer is a continuously evolving field and comprises an interesting area for scientific research. Areas covered: This review encompasses the current literature on nutrition in the pre-operative, peri-operative, and post-operative phases of esophageal cancer. Both established interventions and potential novel targets for nutritional management are discussed. Expert commentary: To ensure an optimal pre-operative status and to reduce peri-operative complications, it is key to assess nutritional status in all pre-operative esophageal cancer patients and to apply nutritional interventions accordingly. Since esophagectomy results in a permanent anatomical change, a special focus on nutritional strategies is needed in the post-operative phase, including early initiation of enteral feeding, nutritional interventions for post-operative complications, and attention to long-term nutritional intake and status. Nutritional aspects of pre-optimization and peri-operative management should be incorporated in novel Enhanced Recovery After Surgery programs for esophageal cancer.

Candida esophagitis in an immunocompetent pregnant woman.

Nausea and vomiting are common during the first half of pregnancy and usually require only supportive measures. When symptoms are progressive and weight loss occurs, treatable causes should be sought by means of upper gastrointestinal endoscopy. We report a case of an immunocompetent gravida with invasive Candida albicans esophagitis. The immunocompetent primigravida developed progressive nausea, vomiting, epigastric pain, and a 4.1 kg weight loss during the second trimester of pregnancy. Treatment with metoclopramide and cimetidine for presumed gastroesophageal reflux was not effective. The patient had normal T-cell CD4 and CD8 subsets and was human immunodeficiency virus (HIV) antibody negative. Upper gastrointestinal endoscopy revealed C. albicans esophagitis which was treated with oral nystatin. The esophagitis had resolved completely when reassessed postpartum. The use of histamine(2) blockers is associated with an increased risk for fungal esophagitis and may have been a contributing cause in this case. Pregnant patients with persistent nausea, vomiting, and weight loss should be evaluated by endoscopy for fungal esophagitis.

Objective To evaluate the authors’ experience with gastric transposition as a method of esophageal replacement in children with congenital or acquired abnormalities of the esophagus. Summary Background Data Esophageal replacement in children is almost always done for benign disease and thus requires a conduit that will last more than 70 years. The organ most commonly used in the past has been colon; however, most series have been fraught with major complications and conduit loss. For these reasons, in 1985 the authors switched from using colon interpositions to gastric transpositions for esophageal replacement in infants and children. Methods The authors retrospectively reviewed the records of 41 patients with the diagnoses of esophageal atresia (n = 26), corrosive injury (n = 8), leiomyomatosis (n = 5), and refractory gastroesophageal reflux (n = 2) who underwent gastric transposition for esophageal replacement. Results Mean ± SE age at the time of gastric transposition was 3.3 ± 0.6 years. All but two transpositions were performed through the posterior mediastinum without mortality or loss of the gastric conduit despite previous surgery on the gastric fundus in 8 (20%), previous esophageal operations in 15 (37%), and previous esophageal perforations in 6 (15%) patients. Complications included esophagogastric anastomotic leak (n = 15, 36%), which uniformly resolved without intervention; stricture formation (n = 20, 49%), all of which no longer require dilation; and feeding intolerance necessitating jejunal feeding (n = 8, 20%) due to delayed gastric emptying (n = 3), feeding aversion related to the underlying anomaly (n = 1), or severe neurological impairment (n = 4). No redo anastomoses were required. Conclusions Gastric transposition reestablishes effective gastrointestinal continuity with few complications. Oral feeding and appropriate weight gain are achieved in most children. Therefore, gastric transposition is an appropriate alternative for esophageal

Esophageal squamous cell carcinoma is one of the most common malignant tumors. The oncogene c-MYC is thought to be important in the initiation, promotion, and therapy resistance of cancer. In this study, we aim to investigate the clinicopathologic roles of c-MYC in esophageal squamous cell carcinoma tissue. This study is aimed at discovering and analyzing c-MYC expression in a series of human esophageal tissues. A total of 95 esophageal squamous cell carcinoma samples were analyzed by the western blotting and immunohistochemistry techniques. Then, correlation of c-MYC expression with clinicopathological features of esophageal squamous cell carcinoma patients was statistically analyzed. In most esophageal squamous cell carcinoma cases, the c-MYC expression was positive in tumor tissues. The positive rate of c-MYC expression in tumor tissues was 61.05%, obviously higher than the adjacent normal tissues (8.42%, 8/92) and atypical hyperplasia tissues (19.75%, 16/95). There was a statistical difference among adjacent normal tissues, atypical hyperplasia tissues, and tumor tissues. Overexpression of the c-MYC was detected in 61.05% (58/95) esophageal squamous cell carcinomas, which was significantly correlated with the degree of differentiation (p = 0.004). The positive rate of c-MYC expression was 40.0% in well-differentiated esophageal tissues, with a significantly statistical difference (p = 0.004). The positive rate of c-MYC was 41.5% in T1 + T2 esophageal tissues and 74.1% in T3 + T4 esophageal tissues, with a significantly statistical difference (p = 0.001). The positive rate of c-MYC was 45.0% in I + II esophageal tissues and 72.2% in III + IV esophageal tissues, with a significantly statistical difference (p = 0.011). The c-MYC expression strongly correlated with clinical staging (p = 0.011), differentiation degree (p = 0.004), lymph node metastasis (p = 0.003), and invasion depth (p = 0.001) of patients with esophageal squamous cell carcinoma.

Sensitization of esophageal chemoreceptors, either directly by intermittent acid exposure or indirectly through esophagitis-associated inflammatory mediators, is likely to be the mechanism underlying the perception of heartburn. To compare basal esophageal sensitivity with electrical stimulation and acid, and to compare the degree of acid-induced sensitization in controls and in patient groups across the entire spectrum of gastroesophageal reflux disease: erosive oesophagitis (EO), nonerosive reflux disease (NERD), and functional heartburn (FH). Esophageal sensory and pain thresholds to electrical stimulation were measured before, 30, and 60 minutes after an intraesophageal infusion of saline or HCl. Patients received a 30-minute infusion of 0.15 M HCl and controls were randomized to receive either HCl (n = 11) or saline (n = 10). After electrical sensory threshold testing, participants received another 30-minute infusion of HCl to determine whether sensitivity to acid is increased by prior acid exposure All patient groups had higher basal sensory thresholds than healthy controls (controls, 13 ± 1.4 mA; FH, 20 ± 5.1 mA; NERD, 21 ± 5.1 mA; EO, 23 ± 5.4 mA; P < 0.05). Acute esophageal acid exposure reduced sensory thresholds to electrical stimulation in FH and NERD patients (P < 0.05). The level of acid sensitivity during the first HCl infusion was comparable between all patient groups and controls. The secondary infusion caused increased discomfort in all participants (P < 0.01). This acid-induced sensitization to HCl was significantly elevated in the patient groups ( P < 0.05). (1) Esophageal acid infusion sensitizes it to subsequent electrical and chemical stimulation. (2) The acid-related sensitization is greater in gastroesophageal reflux disease than in controls and may influence in part symptom perception in this population. (3) Acid-related sensitization within the gastroesophageal reflux disease population is not dependant on mucosal inflammation.

Multimodality therapy for esophageal cancer can cause various kinds of treatment-related sequelae, especially pulmonary toxicities. This prospective study aims to investigate the clinical and dosimetric parameters predicting lung injury in patients undergoing radiation therapy for esophageal cancer. Forty-five esophageal cancer patients were prospectively analyzed. The pulmonary toxicities (or sequelae) were evaluated by comparing chest X-ray films, pulmonary function tests and symptoms caused by pulmonary damage before and after treatment. All patients were treated with either three-dimensional radiotherapy (3DCRT) or with intensity-modulated radiotherapy (IMRT). The planning dose volume histogram was used to compute the lung volumes receiving more than 5, 10, 20 and 30 Gy (V5, V10, V20, V30) and mean lung dose. V20 was larger in the IMRT group than in the 3DCRT group (p = 0.002). V20 (>15%) and V30 (>20%) resulted in a statistically significant increase in the occurrence of chronic pneumonitis (p = 0.03) and acute pneumonitis (p = 0.007), respectively. The study signifies that a larger volume of lung receives lower doses because of multiple beam arrangement and a smaller volume of lung receives higher doses because of better dose conformity in IMRT plans. Acute pneumonitis correlates more with V30 values, whereas chronic pneumonitis was predominantly seen in patients with higher V20 values.

Three lower esophageal sphincter (LES) characteristics associated with gastro-esophageal reflux disease (GERD) are, LES pressure = 6 mmHg, abdominal length (AL) <1 cm and overall length (OL) <2 cm. The objective of this study was to validate this relationship and evaluate the extent of impact various LES characteristics have on the degree of distal esophageal acid exposure. A retrospective review of a prospectively maintained database identified patients who underwent esophageal manometry and pH studies at Creighton University Medical Center between 1984 and 2008. Patients with esophageal body dysmotility, prior foregut surgery, missing data, no documented symptoms or no pH study, were excluded. Study subjects were categorized as follows: (1) normal LES (N-LES): patients with LES pressure of 6-26 mmHg, AL = 1.0 cm and OL = 2 cm; (2) incompetent LES (Inc-LES): patients with LES pressure <6.0 mmHg orAL <1 cm or OL <2 cm; and (3) hypertensive LES (HTN-LES): patients with LES pressure >26.0 mmHg with AL = 1 cm and OL = 2 cm. The DeMeester score was used to compare differences in acid exposure between different groups. Two thousand and twenty patients satisfied study criteria. Distal esophageal acid exposure as reflected by the DeMeester score in patients with Inc-LES (median=20.05) was significantly higher than in patients with an N-LES (median=9.5), which in turn was significantly higher than in patients with an HTN-LES. Increasing LES pressure and AL provided protection against acid exposure in a graded fashion. Increasing number of inadequate LES characteristics were associated with an increase both in the percentage of patients with abnormal DeMeester score and the degree of acid exposure. LES pressure (=6 mmHg) and AL (<1 cm) are associated with increased lower esophageal acid exposure, and need to be addressed for definitive management of GERD.

Purpose: Proton beam therapy (PBT) is a promising modality for the management of thoracic malignancies. We report our preliminary experience of treating esophageal cancer patients with concurrent chemotherapy (CChT) and PBT (CChT/PBT) at MD Anderson Cancer Center. Methods and Materials: This is an analysis of 62 esophageal cancer patients enrolled on a prospective study evaluating normal tissue toxicity from CChT/PBT from 2006 to 2010. Patients were treated with passive scattering PBT with two- or three-field beam arrangement using 180 to 250 MV protons. We used the Kaplan-Meier method to assess time-to-event outcomes and compared the distributions between groups using themore » log-rank test. Results: The median follow-up time was 20.1 months for survivors. The median age was 68 years (range, 38-86). Most patients were males (82%) who had adenocarcinomas (76%) and Stage II-III disease (84%). The median radiation dose was 50.4 Gy (RBE [relative biologic equivalence]) (range, 36-57.6). The most common grade 2 to 3 acute toxicities from CChT/PBT were esophagitis (46.8%), fatigue (43.6%), nausea (33.9%), anorexia (30.1%), and radiation dermatitis (16.1%). There were two cases of grade 2 and 3 radiation pneumonitis and two cases of grade 5 toxicities. A total of 29 patients (46.8%) received preoperative CChT/PBT, with one postoperative death. The pathologic complete response (pCR) rate for the surgical cohort was 28%, and the pCR and near CR rates (0%-1% residual cells) were 50%. While there were significantly fewer local-regional recurrences in the preoperative group (3/29) than in the definitive CChT/PBT group (16/33) (log-rank test, p = 0.005), there were no differences in distant metastatic (DM)-free interval or overall survival (OS) between the two groups. Conclusions: This is the first report of patients treated with PBT/CChT for esophageal cancer. Our data suggest that this modality is associated with a few severe toxicities, but the pathologic response and

We report our preliminary experience of treating esophageal cancer patients with concurrent chemotherapy (CChT) and PBT at MD Anderson Cancer Center. Materials/Methods This is an analysis of 62 esophageal cancer patients enrolled on a prospective study evaluating normal tissue toxicity from CChT/PBT from 2006 to 2010. Patients were treated with Passive Scattering PBT with 2 or 3 field beam arrangement using 180–250 MV protons. We used the method of Kaplan and Meier to assess time to event outcomes and compared the distributions between groups using the log-rank test. Results The median follow-up time was 20.1 months for survivors. The median age was 68 years (range 38–86). Most were males (82%), had adenocarcinomas (76%) and had stage II-III disease (84%). The median radiation dose was 50.4 Gray-Equivalence (Gy(RBE)) (range 36–57.6). The most common grade 2–3 acute toxicities from CChT/PBT were esophagitis (46.8%), fatigue (43.6%), nausea (33.9%), anorexia (30.1%), and radiation dermatitis (16.1%). There were two cases of grade 2 and 3 radiation pneumonitis and two grade 5 toxicities. A total of 29 patients (46.8%) received preoperative CChT/PBT with one postoperative death. The pathologic complete response (pCR) rate for the surgical cohort was 28%, and the pCR and near CR rate (0–1% residual cells) was 50%. While there were significantly fewer local-regional recurrences in the preoperative group (3/29) as compared to the definitive CChT/PBT group (16/33) (log-rank test p=0.005), there were no differences in DM free interval or OS between the two groups. Conclusions This is the first report of patients treated with PBT/CChT for esophageal cancer. Our data suggest that this modality is associated with a few severe toxicities but the pathologic response and clinical outcomes are encouraging.

High-resolution manometry (HRM) has been applied to assess esophageal motility disorders. However, the frequency and types of motility disorders in patients with dysphagia, which are frequently seen in clinical practice, are not clear. We evaluated latent esophageal motility disorders associated with dysphagia. The study included patients without erosive esophageal mucosal damage and with dysphagia symptoms refractory to at least 8 weeks of standard-dose proton pump inhibitors. After enrolment, HRM was used to evaluate for esophageal motility disorder based on the Chicago classification. Esophageal motility disorder was found in 58 of 100 patients and was classified based on the causes: achalasia (13%), esophagogastric junction outflow obstruction (16%), distal esophageal spasms (3%), weak peristalsis (14%), frequently failed peristalsis (5%), and hypertensive peristalsis (7%). Primary esophageal motility disorder was found in approximately 50% of cases in dysphagia patients. Therefore, esophageal motility disorder is not an uncommon condition and should be sought for in order to elucidate precisely the cause of dysphagia. © 2017 S. Karger AG, Basel.

Anastomotic stricture is the most common complication following repair of esophageal atresia. An Esophageal Anastomotic Stricture Index (EASI) based on the postoperative esophagram may identify patients at high risk of stricture formation. Digital images of early postoperative esophagrams of patients undergoing EA repair from 2005 to 2013 were assessed. Demographics and outcomes including dilations were prospectively collected. Upper (U-EASI) and lower (L-EASI) pouch ratios were generated using stricture diameter divided by maximal respective pouch diameter. Score performances were evaluated with area under the receiver operator curves (AUC) and the Fisher's exact test for single and multiple (>3) dilatations. Interrater agreement was evaluated using the intraclass correlation coefficient (ICC). Forty-five patients had esophagrams analyzed; 28 (62%) required dilatation and 19 received >3 (42%). U-EASI and L-EASI ratios ranged from 0.17 to 0.70, with L-EASI outperforming the U-EASI as follows: L-EASI AUC: 0.66 for a single dilatation, 0.65 for >3 dilatations; U-EASI AUC: 0.56 for a single dilatation, 0.67 for >3 dilatations. All patients with an L-EASI ratio of ≤0.30 (n=8) required multiple esophageal dilatations, p=0.0006. The interrater ICC was 0.87. The EASI is a simple, reproducible tool to predict the development and severity of anastomotic stricture after esophageal atresia repair and can direct postoperative surveillance.

The therapeutic gains of neoadjuvant chemoradiation therapy (nCRT) followed by esophagectomy may be offset by increased incidences of morbidity and mortality in elderly patients. This study aimed to determine the impact of age on the risks and benefits of trimodality therapy for esophageal cancer. We evaluated 571 patients treated with trimodality therapy at 3 high-volume tertiary cancer centers in the United States from 2007 to 2013. Two hundred two of 571 (35%) patients were 65 years or older at diagnosis and were classified as elderly. Toxicity and treatment parameters for the elderly cohort were compared with the younger cohort (ages 22-64) by the use of univariate (UVA) and multivariable (MVA) logistic analyses. Age was analyzed as a continuous hazard for cardiac and pulmonary toxicities. Survival was assessed by the Kaplan-Meier method. Elderly patients had a higher risk for postoperative cardiac toxicities (UVA: odds ratio [OR] 2.2, P<.001; MVA: OR 2.07, P=.004) and pulmonary toxicities (UVA: OR 2.0, P<.001; MVA: OR 2.03, P<.001) and a higher 90-day postoperative mortality (5.4% vs 2.2%, P=.049). Of the elderly patients, 6.9% experienced acute respiratory distress syndrome compared with 3.8% of younger patients (P=.11). Cardiac toxicity was linearly associated with age, and the relative risk increased by 61% for every additional decade of age. There was no difference in postoperative gastrointestinal or wound adverse events or in length of hospital stay. Grade 3+ acute toxicities from nCRT were infrequent and were clinically similar regardless of age. Freedom from esophageal cancer and disease-free survival were similar, but overall survival was significantly shorter in the elderly cohort. Elderly patients experienced more postoperative cardiopulmonary toxicities and mortality than did younger patients after nCRT. Compared with contemporary outcomes for trimodality therapy, both cohorts had acceptable rates for adverse events and disease control. For

Diagnosis and management of esophageal achalasia.

2016-09-13

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.

Predictive value of routine esophageal high-resolution manometry for gastro-esophageal reflux disease.

PubMed

2015-07-01

Using conventional manometry, gastro-esophageal reflux disease (GERD) was associated with a reduced lower esophageal sphincter (LES) pressure and impaired peristalsis. However, with a large overlap between GERD patients and controls, these findings are of limited clinical relevance. It is uncertain whether the more detailed information of high-resolution manometry (HRM) can discriminate GERD patients. Therefore, we aimed to determine to which extent HRM findings can predict GERD. HRM measurements in 69 patients with GERD and 40 healthy subjects were compared and the predictive value of HRM for the diagnosis of GERD was explored. GERD patients had a significantly lower contraction amplitude (55 vs 64 mmHg; p = 0.045) and basal LES pressure (10 vs 13.2 mmHg; p = 0.034) than healthy controls. GERD patients more often had a hiatal hernia than healthy subjects (30% vs 7%; p = 0.005). Patients with reflux esophagitis had a lower DCI than patients without reflux esophagitis (558 vs 782 mmHg cm s; p = 0.045). No significant difference was seen in contractile front velocity, distal latency, number of peristaltic breaks, residual LES pressure and LES length. On multivariate logistic regression analysis, both esophagogastric junction type I (OR 4.971; 95% CI 1.33-18.59; p = 0.017) and mean wave amplitude (OR 0.95; 95% CI 0.90-0.98; p = 0.013) were found to be independent predictors of GERD. However, the sensitivity and specificity of these findings were low. Hiatal hernia, low contraction amplitude and LES pressure are associated with GERD, but do not predict the disease with sufficient accuracy. Routine esophageal HRM can therefore not be used to distinguish GERD patients from healthy subjects. © 2015 John Wiley & Sons Ltd.

We investigated whether single nucleotide polymorphisms (SNPs) in the nuclear assembly factor 1 (NAF1) and TNFAIP3-interacting protein 1 (TNIP1) gene were associated with susceptibility to esophageal cancer in a Chinese Han population. Five SNPs were genotyped and their relationship with esophageal cancer risk was analyzed in a sample of 386 esophageal cancer patients and 495 unrelated healthy controls recruited from the First Affiliated Hospital of Xi'an Jiaotong University. Patients with the AG genotype of rs2320615 were at lower risk of developing esophageal cancer than those with the GG genotype (adjusted odds ratio [OR] = 0.64, 95% confidence interval [CI] = 0.46-0.90, P = 0.009). The rs2320615 SNP was found to be associated with a decreased the risk of esophageal cancer in the dominant model (adjusted OR = 0.70, 95% CI = 0.51-0.96, P = 0.026). These results provide the first evidence that the rs2320615 in NAF1 was associated with reduced risk of esophageal cancer. Further studies with larger samples are warranted to confirm our findings.

Acute administration of the oral 5-HT1A receptor agonist buspirone, which is commonly used as an anxiolytic drug, may improve compromised lower esophageal sphincter function. In an open-label trial we assessed the effects of buspirone on esophageal motor function and symptoms in patients with esophageal involvement associated with systemic sclerosis (SSc). Thirty consecutive patients with SSc and symptomatic esophageal involvement, despite treatment with proton pump inhibitors, underwent high resolution manometry and chest computed tomography for assessment of motor function and esophageal dilatation, respectively. Regurgitation, heartburn, dysphagia, and chest pain severity was subjectively scored by visual analog scales. Manometric parameters (primary endpoint) and symptom severity (secondary endpoint) were re-examined after 4-week daily administration of 20 mg buspirone. Other medications remained unchanged. Eight patients did not complete the trial because of buspirone-associated dizziness (n = 2), or nausea (n = 2), or reluctancy to undergo final manometry. In the remaining 22 patients lower esophageal sphincter (LES) resting pressure increased from 7.7 ± 3.9 to 12.2 ± 4.6 mmHg (p = 0.00002) after buspirone administration; other manometric parameters did not change. Statistical analysis revealed negative correlation between individual increases in resting LES pressure and supra-aortic esophageal diameter (r = -0.589, p = 0.017), suggesting a more beneficial effect in patients with less severely affected esophageal function. Heartburn and regurgitation scores decreased at 4 weeks compared to baseline (p = 0.001, and p = 0.022, respectively). Our findings warrant more conclusive evaluation with a double-blind controlled study; however, buspirone could potentially be given under observation for objective improvement in all patients with SSc who report reflux symptoms despite undergoing standard treatment.

Esophageal reconstruction presents a significant clinical challenge in patients ranging from neonates with long-gap esophageal atresia to adults after esophageal resection. Both gastric and colonic replacement conduits carry significant morbidity. As emerging organ-sparring techniques become established for early stage esophageal tumors, less morbid reconstruction techniques are warranted. We present two novel endoscopic approaches for esophageal lengthening and reconstruction in a porcine model. Two models of esophageal defects were created in pigs (30-35 kg) under general anesthesia and subsequently reconstructed with the novel techniques. The first model was a segmental defect of the esophagus created by thoracoscopically transecting the esophagus above the gastroesophageal (GE) junction. The first reconstruction technique involved bilateral submucosal endoscopic lengthening myotomies (BSELM) with a magnetic compression anastomosis (MAGNAMOSIS™). The second model was a wedge defect in the anterior esophagus created above the GE junction through a laparotomy. The second reconstruction technique involved an inverted mucosal-submucosal sleeve transposition graft (IMSTG) that crossed the esophageal gap and was secured in place with a self-expandable covered esophageal stent. Both techniques were feasible in the pig model. The BSELM approach lengthened the esophagus 1 cm for every 2 cm length of myotomy. The myotomy targeted only the inner circular fibers of the esophagus, with preservation of the longitudinal layer to protect against long-term dilation and pouching. The IMSTG approach generated a vascularized mucosal graft almost as long as the esophagus itself. Emerging endoscopic capabilities are enabling complex endoluminal esophageal procedures. BSELM and IMSTG are two novel and technically feasible approaches to esophageal lengthening and reconstruction. Further survival studies are needed to establish the safety and efficacy of these techniques.

The fundamental pathogenesis of Behçet disease (BD) is still unclear and controversial. Many cases of oral aphthous ulcers and genital ulcers related to BD are reported; nevertheless, idiopathic giant esophageal ulcers related to BD are rare. A rare case for esophageal ulcers related to BD is presented. In China, BD is represented with esophageal involvement which is called esophageal BD (EBD). A 56-year-old man diagnosed to the Gastroenterology Department of Integrated Traditional Chinese and Western Medicine Hospital, for multiple discrete, elliptical esophageal ulcers related to BD. The esophageal ulcers were treated with corticosteroid treatment for 12 weeks. The esophageal ulcers were cured. Our report might give further strength to avoiding the erroneous diagnosis or missed diagnosis for EBD, which is different from esophageal carcinoma, esophageal tuberculosis and esophageal Crohns disease.

Androgens and esophageal cancer: What do we know?

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 role of contemporary radiotherapy (RT) has not yet been elucidated, mainly because of the low incidence of cervical esophageal cancer. The purpose of this study was to analyze the outcome in patients with cervical esophageal cancer treated with definitive RT. A total of 115 patients with cervical esophageal cancer treated with definitive RT during January 2001 through April 2012 in our center were analyzed. Eighty patients received RT alone and 35 patients received concurrent chemoradiotherapy with cisplatin administered either weekly (30 mg/m2) or every 3 weeks (80 mg/m2). The median follow-up time was 17.1 months. For all patients, the overall 2-year local failure-free survival (LFFS), regional failure-free survival (RFFS), distant failure-free survival (DFFS), and overall survival (OS) rate was 68.3%, 83.3%, 75.7%, and 47.6%, respectively. Definitive RT accomplished a satisfactory local control rate and contributed to organ preservation for patients with cervical esophageal cancer. 2015. © 2014 Wiley Periodicals, Inc.

Challenges in oral drug delivery in patients with esophageal dysphagia.

PubMed

Kappelle, Wouter F W; Siersema, Peter D; Bogte, Auke; Vleggaar, Frank P

2016-01-01

Esophageal dysphagia is a commonly reported symptom with various benign and malignant causes. Esophageal dysphagia can impede intake of oral medication, which often poses a major challenge for both patients and physicians. The best way to address this challenge depends of the cause of dysphagia. The pathophysiology of esophageal dysphagia is discussed, diagnostic tools to determine its cause are reviewed and recent developments in the treatment of esophageal dysphagia are discussed. Alternative options to administer medication in dysphagia are discussed and the appropriateness of them reviewed. Two ways can be followed to allow medication intake in patients with esophageal dysphagia, i.e. altering medication or resolving dysphagia. The latter is generally preferred, since esophageal dysphagia rarely only impedes medication intake. Esophageal resection is possible in more advanced esophageal cancer stages due to advances in neo-adjuvant therapy. Due to recent improvements in intraluminal radiotherapy, it can be expected that this will be the primary treatment in a palliative setting. Temporary self-expandable metal stent placement is a promising new alternative for bougienage in difficult-to-treat benign strictures.

Effect of aging on the esophageal motor functions.

To clarify the changes of esophageal motility along with age, we performed esophageal manometry on 47 healthy volunteers, and compared the values of four groups under 49 years old (n = 11), 50 to 59 (n = 15), 60 to 69 (n = 11), and over 70 years old (n = 10). Resting lower esophageal sphincter (LES) pressure in the group over 70 years old showed the tendency of decrease, but not statistically significant. Nadir LES pressure on swallow-induced relaxation was not statistically different among 4 groups. On esophageal body testing, percentage of non-conduction sequence in the group 60 to 69 and over 70 years old was statistically higher compared with that of the group under 49 years old (p < 0.05) but spared in some elderly subjects. Percentage of simultaneous contractions was not statistically different among 4 groups. Peristaltic contraction amplitude in the group over 70 years old was significantly lower than that of the group under 49 years old both at the level of 5 cm above (p < 0.01) and 10 cm above LES (p < 0.05). We speculate that the influence of aging on esophageal motility is the reduced transmission sequence of peristalsis and contractility of esophageal body. This alteration along with age may differ from the pathological condition of scleroderma or diffuse esophageal spasm.

Gastroesophageal reflux disease is a condition frequently associated with esophagitis and motor abnormalities. Recent evidence suggests that proinflammatory cytokines, such as interleukin (IL)-1beta and IL-6, may be implicated because they reduce esophageal muscle contractility, but these results derive from in vitro or animal models of esophagitis. This study used human esophageal cells and tissues to identify the cellular source of cytokines in human esophagitis investigate whether cytokines can be induced by gastric refluxate, and examine whether esophageal tissue- or cell-derived mediators affect muscle contractility. Endoscopic mucosal biopsy specimens were obtained from patients with and without esophagitis, organ-cultured, and undernatants were assessed for cytokine content. The cytokine profile of esophageal epithelial, fibroblast, and muscle cells was analyzed, and esophageal mucosa and cell products were tested in an esophageal circular muscle contraction assay. The mucosa of esophagitis patients produced significantly greater amounts of IL-1beta and IL-6 compared with those of control patients. Cultured esophageal epithelial cells produced IL-6, as did fibroblasts and muscle cells. Epithelial cells exposed to buffered, but not denatured, gastric juice produced IL-6. Undernatants of mucosal biopsy cultures from esophagitis patients reduced esophageal muscle contraction, as did supernatants from esophageal epithelial cell cultures. The human esophagus produces cytokines capable of reducing contractility of esophageal muscle cells. Exposure to gastric juice is sufficient to stimulate esophageal epithelial cells to produce IL-6, a cytokine able to alter esophageal contractility. These results indicate that classic cytokines are important mediators of the motor disturbances associated with human esophageal inflammation.

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.

Manometry is the gold-standard diagnostic test for motility disorders in the esophagus. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The diagnostic value of particular esophageal clinical symptoms among patients suspected of esophageal motor disorders (EMDs) is still unknown. The aim of this study was to explore the sensitivity, specificity, and predictive accuracy of presenting esophageal symptoms between abnormal and normal esophageal manometry findings. We conducted a cross-sectional study of 623 patients aged 11-80 years. Data were collected from clinical examinations as well as patient questionnaires. The sensitivity, specificity, and accuracy were calculated after high-resolution manometry plots were reviewed according to the most recent Chicago Criteria. The clinical symptoms were not sensitive enough to discriminate between EMDs. Nevertheless, dysphagia, noncardiac chest pain, hoarseness, vomiting, and weight loss had high specificity and high accuracy to distinguish EMDs from normal findings. Regurgitation and heartburn did not have good accuracy for the diagnosis of EMDs. Clinical symptoms are not reliable enough to discriminate between EMDs. Clinical symptoms can, however, discriminate between normal findings and EMDs, especially achalasia.

Radiotherapy for breast cancer may expose the esophagus to ionizing radiation, but no study has evaluated esophageal cancer risk after breast cancer associated with radiation dose or systemic therapy use. Nested case-control study of esophageal cancer among 289 748 ≥5-year survivors of female breast cancer from five population-based cancer registries (252 cases, 488 individually matched controls), with individualized radiation dosimetry and information abstracted from medical records. The largest contributors to esophageal radiation exposure were supraclavicular and internal mammary chain treatments. Esophageal cancer risk increased with increasing radiation dose to the esophageal tumor location (P(trend )< 0.001), with doses of ≥35 Gy associated with an odds ratio (OR) of 8.3 [95% confidence interval (CI) 2.7-28]. Patients with hormonal therapy ≤5 years preceding esophageal cancer diagnosis had lower risk (OR = 0.4, 95% CI 0.2-0.8). Based on few cases, alkylating agent chemotherapy did not appear to affect risk. Our data were consistent with a multiplicative effect of radiation and other esophageal cancer risk factors (e.g. smoking). Esophageal cancer is a radiation dose-related complication of radiotherapy for breast cancer, but absolute risk is low. At higher esophageal doses, the risk warrants consideration in radiotherapy risk assessment and long-term follow-up.

A novel disposable transnasal endoscopy (DTE) with a portable system has been developed to provide unsedated esophagoscopy by modifying capsule endoscopy. The aim of this study was to assess the feasibility of DTE to evaluate esophageal motor function. Patients with or suspected esophageal motility disorders and healthy volunteers were enrolled. Participants underwent esophageal high-resolution manometry and DTE in random order on different days. Motility was observed with DTE at 1, 8, and 16 cm above the gastroesophageal junction. Twenty healthy volunteers and 20 symptomatic subjects participated (8 achalasia, 5 scleroderma, 3 diffuse esophageal spasm, 1 hypertensive peristalsis, 1 peristaltic dysfunction, and 22 normal esophageal function). The normal findings on DTE were as follows. As the subject swallowed water, swallow-induced relaxation with elevation of the lower esophageal sphincter caused the endoscope to cross the Z-line into the gastric lumen. After the passage of water and air, complete closure of the lower esophageal sphincter occurred, with the return of the endoscope to its previous position. During the resting stage of the esophageal body, an air bubble could be seen in the center of the radially wrinkled and occluded lumen. The endoscopic diagnosis was in agreement with the clinical diagnosis in all but 2. Most of the participants reported acceptable discomfort during DTE and 62.5% of the subjects preferred DTE to manometry. DTE can accurately characterize normal esophageal motor function, allowing the diagnosis of esophageal motility disorders. DTE has potential widespread applications, especially in outpatient clinics.

The effect of endoscopic submucosal dissection (ESD) on esophageal motility remains unknown. Therefore, the aim of this study is to elucidate changes in esophageal motility after ESD along with the cause of dysphagia using high-resolution manometry (HRM). This is a before-and-after trial of the effect of ESD on the esophageal motility. Twenty patients who underwent ESD for superficial esophageal carcinoma were enrolled in this study. Patients filled out a questionnaire about dysphagia and underwent HRM before and after ESD. Results before and after ESD were compared. Data were obtained from 19 patients. The number of patients who complained of dysphagia before and after ESD was 1/19 (5.3%) and 6/19 (31.6%), respectively (P = 0.131). Scores from the five-point Likert scale before and after ESD were 0.1 ± 0.5 and 1.0 ± 1.6, respectively (P = 0.043). The distal contractile integral (DCI) before and after ESD and the number of failed, weak, or fragmented contractions were not significantly different. However, in five patients with circumferential ESD, DCI was remarkably decreased and the frequency of fail, weak, or fragmented contractions increased. Univariate regression analysis showed a relatively strong inverse correlation of ΔDCI with the circumferential mucosal defect ratio {P < 0.01, standardized regression coefficient (r) = -0.65}, the number of stricture preventions (P < 0.01, r = -0.601), and the number of stricture resolutions (P < 0.01, r = -0.77). This HRM study showed that impairment of esophageal motility could be caused by ESD. The impairment of esophageal motility was conspicuous, especially in patients with circumferential ESD and subsequent procedures such as endoscopic triamcinolone injection and endoscopic balloon dilatation. Impaired esophageal motility after ESD might explain dysphagia. © The Authors 2017. Published by Oxford University Press on behalf of International Society for Diseases of the Esophagus.

Although saponification of the pancreas is a frequent finding on computed tomography, saponification of extrapancreatic mesenteric sites has not been previously recognized. A case is presented of acute pancreatitis in which serial scans over a four-year period documented calcifications in old extrapancreatic phlegmons. Saponification from pancreatitis should be considered in the differential diagnosis of mesenteric calcifications.

Upper gastrointestinal (GI) symptoms are common in both HIV and non-HIV-infected patients, but the difference of GI symptom severity between 2 groups remains unknown. Candida esophagitis and erosive esophagitis, 2 major types of esophagitis, are seen in both HIV and non-HIV-infected patients, but differences in GI symptoms that are predictive of esophagitis between 2 groups remain unknown. We aimed to determine whether GI symptoms differ between HIV-infected and non-HIV-infected patients, and identify specific symptoms of candida esophagitis and erosive esophagitis between 2 groups.We prospectively enrolled 6011 patients (HIV, 430; non-HIV, 5581) who underwent endoscopy and completed questionnaires. Nine upper GI symptoms (epigastric pain, heartburn, acid regurgitation, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia) were evaluated using a 7-point Likert scale. Associations between esophagitis and symptoms were analyzed by the multivariate logistic regression model adjusted for age, sex, and proton pump inhibitors.Endoscopy revealed GI-organic diseases in 33.4% (2010/6.011) of patients. The prevalence of candida esophagitis and erosive esophagitis was 11.2% and 12.1% in HIV-infected patients, respectively, whereas it was 2.9% and 10.7 % in non-HIV-infected patients, respectively. After excluding GI-organic diseases, HIV-infected patients had significantly (P < 0.05) higher symptom scores for heartburn, hunger cramps, nausea, early satiety, belching, dysphagia, and odynophagia than non-HIV-infected patients. In HIV-infected patients, any symptom was not significantly associated with CD4 cell count. In multivariate analysis, none of the 9 GI symptoms were associated with candida esophagitis in HIV-infected patients, whereas dysphagia and odynophagia were independently (P < 0.05) associated with candida esophagitis in non-HIV-infected patients. However, heartburn and acid regurgitation were independently (P < 0.05) associated with erosive

Esophageal surgery in minimally invasive era

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.

Eosinophilic esophagitis: a bulk of mysteries.

PubMed

Straumann, Alex

2013-01-01

Eosinophilic esophagitis (EoE), which was first described in the early 1990s, has rapidly evolved as a distinctive chronic inflammatory esophageal disease. The diagnosis is based clinically on the presence of symptoms related to esophageal dysfunction and histologically by an eosinophil-predominant inflammation once other conditions leading to esophageal eosinophilia are excluded. This striking male-prevalent disease has an increasing incidence and prevalence in the Westernized countries. Currently, EoE represents the main cause of dysphagia and bolus impaction in adult patients. Despite the fact that EoE often occurs in atopic patients, the value of allergic testing is still under discussion. Topical corticosteroids lead to a rapid improvement of active EoE clinically and histologically; they are therefore regarded as first-line drug therapy. Elimination diets have similar efficacy as topical corticosteroids, but their long-term use is limited by practical issues. Esophageal dilation of EoE-induced strictures can also be effective in improving symptoms, but this therapy has no effect on the underlying inflammation. Neither the diagnostic nor the long-term therapeutic strategies have been fully defined. Currently, the list of unsolved issues--or mysteries--is still long and a concerted effort on behalf of clinicians and scientists is required to improve the understanding and the therapeutic management of this mysterious disease.

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 (TME), 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. Antitumor immunity is attenuated by cell populations such as myeloid-derived suppressor cells and regulatory T cells, as well as immune checkpoints like programmed death-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 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.

Plummer-Vinson Syndrome with Proximal Esophageal Web.

Changela, Kinesh; Haeri, Nami Safai; Krishnaiah, Mahesh; Reddy, Madhavi

2016-05-01

Plummer-Vinson Syndrome is a condition where iron deficiency is associated with difficulty swallowing due to the presence of an esophageal web. Deficiency of iron-dependent oxidative enzymes causes gradual degradation of the pharyngeal muscles which lead to mucosal atrophy and formation of webs. Although it is a very rare condition, an increased risk of esophageal squamous cell carcinoma makes its identification very important. Dilation of the esophageal web using a Savary dilator is a more effective and safer approach compared to conventional balloon dilation.

The purpose of this study was to describe the clinical presentation of children with either an unwitnessed or witnessed esophageal foreign body. Retrospective chart review was performed. Patients were identified using ICD-9 code for esophageal foreign body. Clinical data and management techniques, along with complications were abstracted. For the 5-year period of review, 255 patients were identified with an esophageal foreign body. 214 children had a witnessed ingestion. The mean age of the unwitnessed ingestion group was 2.3 years, compared to 4.6 years for a witnessed ingestion. In both groups, males and females were distributed equally and the most common ingested object was a coin. Bivariate, unadjusted analysis revealed that history of wheeze (OR, 4.35) and fever (OR, 11.15) had the largest association with patients who had an unwitnessed ingestion. Multivariate analysis indicated that any physical findings of wheeze, rhonchi, stridor, or retractions were associated significantly with a diagnosis of an unwitnessed foreign body. Children less than 2 years of age and with a documented fever are also predictive of an unwitnessed ingestion. Eleven children (4.3%) with esophageal abnormalities were also noted to have foreign bodies. Children who present to the emergency department two years old and younger, who have a documented fever and with respiratory findings should be considered at risk for having a retained esophageal foreign body. Children with esophageal abnormalities may also be at risk for retained esophageal foreign bodies.

Background and Study Aims Endoscopic diagnosis of esophageal achalasia lacking typical endoscopic features can be extremely difficult. The aim of this study was to identify simple and reliable early indicator of esophageal achalasia. Patients and Methods This single-center retrospective study included 56 cases of esophageal achalasia without previous treatment. As a control, 60 non-achalasia subjects including reflux esophagitis and superficial esophageal cancer were also included in this study. Endoscopic findings were evaluated according to Descriptive Rules for Achalasia of the Esophagus as follows: (1) esophageal dilatation, (2) abnormal retention of liquid and/or food, (3) whitish change of the mucosal surface, (4) functional stenosis of the esophago-gastric junction, and (5) abnormal contraction. Additionally, the presence of the longitudinal superficial wrinkles of esophageal mucosa, “pinstripe pattern (PSP)” was evaluated endoscopically. Then, inter-observer diagnostic agreement was assessed for each finding. Results The prevalence rates of the above-mentioned findings (1–5) were 41.1%, 41.1%, 16.1%, 94.6%, and 43.9%, respectively. PSP was observed in 60.7% of achalasia, while none of the control showed positivity for PSP. PSP was observed in 26 (62.5%) of 35 cases with shorter history < 10 years, which usually lacks typical findings such as severe esophageal dilation and tortuosity. Inter-observer agreement level was substantial for food/liquid remnant (k = 0.6861) and PSP (k = 0.6098), and was fair for abnormal contraction and white change. The accuracy, sensitivity, and specificity for achalasia were 83.8%, 64.7%, and 100%, respectively. Conclusion “Pinstripe pattern” could be a reliable indicator for early discrimination of primary esophageal achalasia. PMID:25664812

Generation and Characterization of an Immortalized Human Esophageal Myofibroblast Line.

Stromal cells with a myofibroblast phenotype present in the normal human esophagus are increased in individuals with gastro-esophageal reflux disease (GERD). We have previously demonstrated that myofibroblasts stimulated with acid and TLR4 agonists increase IL-6 and IL-8 secretion using primary cultures of myofibroblasts established from normal human esophagus. While primary cultures have the advantage of reflecting the in vivo environment, a short life span and unavoidable heterogeneity limits the usefulness of this model in larger scale in vitro cellular signaling studies. The major aim of this paper therefore was to generate a human esophageal myofibroblast line with an extended lifespan. In the work presented here we have generated and characterized an immortalized human esophageal myofibroblast line by transfection with a commercially available GFP-hTERT lentivirus. Immortalized human esophageal myofibroblasts demonstrate phenotypic, genotypic and functional similarity to primary cultures of esophageal myofibroblasts we have previously described. We found that immortalized esophageal myofibroblasts retain myofibroblast spindle-shaped morphology at low and high confluence beyond passage 80, and express α-SMA, vimentin, and CD90 myofibroblast markers. Immortalized human esophageal myofibroblasts also express the putative acid receptor TRPV1 and TLR4 and retain the functional capacity to respond to stimuli encountered in GERD with secretion of IL-6. Finally, immortalized human esophageal myofibroblasts also support the stratified growth of squamous esophageal epithelial cells in 3D organotypic cultures. This newly characterized immortalized human esophageal myofibroblast cell line can be used in future cellular signaling and co-culture studies.

We have recognized a unique clinical syndrome in patients with upper gastrointestinal bleeding who are found to have severe esophagitis. We aimed to more clearly describe the clinical entity of upper gastrointestinal bleeding in patients with severe esophagitis. We conducted a retrospective matched case-control study designed to investigate clinical features in patients with carefully defined upper gastrointestinal bleeding and severe esophagitis. Patient data were captured prospectively via a Gastrointestinal Bleeding Healthcare Registry, which collects data on all patients admitted with gastrointestinal bleeding. Patients with endoscopically documented esophagitis (cases) were matched with randomly selected controls that had upper gastrointestinal bleeding caused by other lesions. Epidemiologic features in patients with esophagitis were similar to those with other causes of upper gastrointestinal bleeding. However, hematemesis was more common in patients with esophagitis 86% (102/119) than in controls 55% (196/357) (p < 0.0001), while melena was less common in patients with esophagitis 38% (45/119) than in controls 68% (244/357) (p < 0.0001). Additionally, the more severe the esophagitis, the more frequent was melena. Patients with esophagitis had less abnormal vital signs, lesser decreases in hematocrit, and lesser increases in BUN. Both pre- and postRockall scores were lower in patients with esophagitis compared with controls (p = 0.01, and p < 0.0001, respectively). Length of hospital stay (p = 0.002), rebleeding rate at 42 days (p = 0.0007), and mortality were less in patients with esophagitis than controls. Finally, analysis of patients with esophagitis and cirrhosis suggested that this group of patients had more severe bleeding than those without cirrhosis. We have described a unique clinical syndrome in patients with upper gastrointestinal bleeding who have erosive esophagitis. This syndrome is manifest by typical clinical features and is associated with

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.

2013-01-01

Background & Aim Large hiatal hernias can be associated with a shortened or tortuous esophagus. We hypothesized that these anatomic changes may alter esophageal pressure topography (EPT) measurements made during high-resolution manometry (HRM). Our aim was to compare EPT measures of esophageal motility in patients with large hiatal hernias to those of patients without hernia. Methods Among 2000 consecutive clinical EPT, we identified 90 patients with large (>5 cm) hiatal hernias on endoscopy and at least 7 evaluable swallows on EPT. Within the same database a control group without hernia was selected. EPT was analyzed for lower esophageal sphincter (LES) pressure, Distal Contractile Integral (DCI), contraction amplitude, Contractile Front Velocity (CFV) and Distal Latency time (DL). Esophageal length was measured on EPT from the distal border of upper esophageal sphincter to the proximal border of the LES. EPT diagnosis was based on the Chicago Classification. Results The manometry catheter was coiled in the hernia and did not traverse the crural diaphragm in 44 patients (49%) with large hernia. Patients with large hernias had lower average LES pressures, lower DCI, slower CFV and shorter DL than patients without hernia. They also exhibited a shorter mean esophageal length. However, the distribution of peristaltic abnormalities was not different in patients with and without large hernia. Conclusions Patients with large hernias had an alteration of EPT measurements as a consequence of the associated shortened esophagus. However, the distribution of peristaltic disorders was unaffected by the presence of hernia. PMID:22508779

Endoscopic submucosal dissection (ESD) is used to perform en block resection for esophageal squamous cell carcinoma, but it is strongly associated with postoperative stenosis, especially during entire circumferential resection. This study aimed to clarify the risk factors for refractory postoperative stenosis after entire circumferential esophageal ESD. Nineteen patients who underwent entire circumferential esophageal ESD from February 2006 to December 2013 at Hiroshima University Hospital were divided into two groups: refractory postoperative stenosis [≥6 endoscopic balloon dilation (EBD) procedures, 12 lesions in 12 patients] and non-refractory postoperative stenosis (≤5 EBD procedures, 7 lesions in 7 patients). We retrospectively examined the patient factors (age, sex, alcohol consumption, smoking index, and chemoradiation therapy history), tumor factors (location, macroscopic type, fibrosis, and depth), and treatment factors (mean procedure time, entire circumferential resection diameter, muscle layer damage, and steroid administration method) between the two groups. Muscle layer damage (p = 0.019) and ≥5 cm of longitudinal mucosal defect length after entire circumferential esophageal ESD (p = 0.010) were significant factors associated with the refractory group. Regarding the patient and tumor factors, there were no significant differences between the two groups. Our data suggest that refractory post-ESD stenosis occurs after entire circumferential esophageal ESD with muscle layer damage and ≥5 cm of longitudinal mucosal defect length.

Tissue engineering, which consists of the combination and in vivo implantation of elements required for tissue remodeling toward a specific organ phenotype, could be an alternative for classical techniques of esophageal replacement. The current hybrid approach entails creation of an esophageal substitute composed of an acellular matrix and autologous epithelial and muscle cells provides the most successful results. Current research is based on the use of mesenchymal stem cells, whose potential for differentiation and proangioogenic, immune-modulator and anti-inflammatory properties are important assets. In the near future, esophageal substitutes could be constructed from acellular "intelligent matrices" that contain the molecules necessary for tissue regeneration; this should allow circumvention of the implantation step and still obtain standardized in vivo biological responses. At present, tissue engineering applications to esophageal replacement are limited to enlargement plasties with absorbable, non-cellular matrices. Nevertheless, the application of existing clinical techniques for replacement of other organs by tissue engineering in combination with a multiplication of translational research protocols for esophageal replacement in large animals should soon pave the way for health agencies to authorize clinical trials.

Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

To analyze the clinical impact of esophageal sparing on treatment plans for patients with grade 3 esophagitis. The treatment plans of 8 patients (project total: 20 patients) who were treated with IMRT and exhibited stage 3 esophagitis were re-planned to give a simulated clinical plan with dose distribution that mirrored our current clinical practice (74Gy to the target, and 5mm margins), and a plan that emphasized esophageal sparing. Doses to the esophagus, heart, cord, lung and PTV were compared. Comparing the esophageal sparing plan to the simulated clinical plan, the mean reduction in esophageal volume receiving 50, 55, 60, 65, and 70Gy were 2.0, 3.2, 5.0, 7.2, and 10.9 cm 3 , respectively. The mean reduction in the continuous length of esophagus receiving 50, 55, 60, 65, and 70Gy were 12, 24, 38, 40, and 47mm, respectively. The associated reduction in dose to 90% and 95% of the PTV was 2.2 and 3.8Gy, respectively. Of the 8 patients examined, 2 showed a significant decrease in PTV coverage (4.6Gy, 12.3Gy for 90% of PTV), 4 showed decreases under 1.1Gy, but 2 showed an increase of 1.4Gy and 0.5Gy for 90% PTV. Cord dose was maintained below 50Gy, and there was a slight increase in mean heart dose and mean lung dose of 2.4Gy, and 2.7Gy, respectively. Data will also be presented comparing these plans with the actual treated plans (for which the patients had grade 3 esophagitis) and plans that emphasize PTV coverage. Treatment planning to emphasize esophageal sparing can reduce the volume and continuous length of the esophagus which receives high doses. There is some associated modest reduction in PTV coverage. In summary, in many cases esophageal sparing can be accomplished for lung cancer cases while maintaining adequate PTV coverage, although there is variability between patients. © 2012 American Association of Physicists in Medicine.

To assess the outcome of different treatments in patients admitted for esophageal achalasia in the United States. This is a retrospective analysis using the Nationwide Inpatient Sample over an 8-year period (2003-2010). Patients admitted with a primary diagnosis of achalasia were divided into 3 groups based on their treatment: (1) Group 1: patients who underwent Heller myotomy during their hospital stay; (2) Group 2: patients who underwent esophagectomy; and (3) Group 3: patients not undergoing surgical treatment. Primary outcome was in-hospital mortality. Secondary outcomes included length of stay (LOS), discharge destination and total hospital charges. Among 27141 patients admitted with achalasia, nearly half (48.5%) underwent Heller myotomy, 2.5% underwent esophagectomy and 49.0% had endoscopic or other treatment. Patients in group 1 were younger, healthier, and had the lowest mortality when compared with the other two groups. Group 2 had the highest LOS and hospital charges among all groups. Group 3 had the highest mortality (1.2%, P < 0.001) and the lowest home discharge rate (78.8%) when compared to the other groups. The most frequently performed procedures among group 3 were esophageal dilatation (25.9%) and injection (13.3%). Among patients who died in this group the most common associated morbidities included acute respiratory failure, sepsis and aspiration pneumonia. Surgery for achalasia carries exceedingly low mortality in the modern era; however, in complicated patients, even less invasive treatments are burdened by significant mortality and morbidity.

Esophageal involvement in Hodgkin's disease, commonly known as a belated localization of the advanced forms, has been seldom reported (3 to 5% in post-mortem series and 0.7% in clinical series). We report the case of a 61-year-old man who had an esophagus localization revealing Hodgkin's disease stage IV EBb of Ann Arbor classification. The originality of this case was represented by: the revelation mode of the esophageal involvement such as dysphagia and upper gastrointestinal bleeding; the localization at the distal third of the esophagus with contiguous involvement of the gastric fundus; the absence of mediastinal nodes showing the primitive character of the esophageal injury. This observation incites us to consider Hodgkin's disease in the list of differential diagnoses of tumoral dysphagia, even if there was no ganglionic and/or visceral localization of the disease.

Congenital esophageal stenosis (CES) is a rare congenital abnormality that is difficult to diagnose and often masquerades as other types of structural esophageal disease. We report three cases of CES with different presenting symptoms. We advocate for balloon dilation as the preferred first approach to therapeutic intervention. CES is an important clinical entity in the evaluation of pediatric esophageal disorders and should be suspected in young infants with dysphagia.

Esophageal motor function in Graves' disease.

Meshkinpour, H; Afrasiabi, M A; Valenta, L J

1979-02-01

Esophageal motor function was studied in 10 patients with untreated Graves' disease and 15 healthy volunteers who served as controls. A noncompliant recording system with a triple-lumen assembly was used. Resting upper- and lower-esophageal-sphincter pressures, amplitude, duration, and velocity of peristaltic contractions in the body of the esophagus, and the number of repetitive and simultaneous contractions were measured. There was no significant difference in peristaltic amplitude and duration between the controls and the patients with Graves' disease. However, there was a significant increase in velocity of contractions in Graves' disease as compared with controls. On restudy of 5 patients who became euthyroid after treatment with 131I, all the measured parameters were unchanged except for velocity of the peristaltic contractions. The value for this measurement decreased essentially to the same as that found in the control subjects. It is concluded that: (1) thyrotoxicosis increases the propagation velocity of esophageal contraction, and (2) thyroid hormones may play a physiologic role in the control of esophageal motor function.

To define the factors predisposing to recurrence and evaluate the results of reoperations for achalasia. We reviewed the medical records of ten patients (4 men and 6 women; mean age, 51.5 ± 11.0 years), who underwent reoperations for achalasia between August 1994 and August 2010. The primary surgical procedures were Heller-Dor (HD) cardioplasty in nine patients and Heller myotomy in one patient. The factors contributing to failure of the primary operation included inadequate myotomy (n = 2), recurrent adhesion after myotomy (n = 2), reflux esophagitis (n = 2), difficulty in passage caused by tortuosity of the esophagus (n = 2), difficulty in passage through the thoracic esophagus (n = 1), and severe chest pain (n = 1). The reoperations included repeated HD procedures (n = 4), repair of an esophageal hiatal hernia (n = 2), thoracic esophageal myotomy (n = 2), straightening of the lower esophagus with gastropexy (n = 1), and subtotal esophagectomy (n = 1). The success rate of the reoperations for resolving symptoms was 90 % (9 patients). Selecting surgical procedures based on the causes and conditions of recurrence led to symptomatic improvement and acceptable outcomes.

Physical activity is associated with reduced risk of esophageal cancer, particularly esophageal adenocarcinoma: a systematic review and meta-analysis

PubMed Central

2014-01-01

Background Physical activity has been inversely associated with risk of several cancers. We performed a systematic review and meta-analysis to evaluate the association between physical activity and risk of esophageal cancer (esophageal adenocarcinoma [EAC] and/or esophageal squamous cell carcinoma [ESCC]). Methods We conducted a comprehensive search of bibliographic databases and conference proceedings from inception through February 2013 for observational studies that examined associations between recreational and/or occupational physical activity and esophageal cancer risk. Summary adjusted odds ratio (OR) estimates with 95% confidence intervals (CI) were estimated using the random-effects model. Results The analysis included 9 studies (4 cohort, 5 case–control) reporting 1,871 cases of esophageal cancer among 1,381,844 patients. Meta-analysis demonstrated that the risk of esophageal cancer was 29% lower among the most physically active compared to the least physically active subjects (OR, 0.71; 95% CI, 0.57-0.89), with moderate heterogeneity (I2 = 47%). On histology-specific analysis, physical activity was associated with a 32% decreased risk of EAC (4 studies, 503 cases of EAC; OR, 0.68; 95% CI, 0.55-0.85) with minimal heterogeneity (I2 = 0%). There were only 3 studies reporting the association between physical activity and risk of ESCC with conflicting results, and the meta-analysis demonstrated a null association (OR, 1.10; 95% CI, 0.21-5.64). The results were consistent across study design, geographic location and study quality, with a non-significant trend towards a dose–response relationship. Conclusions Meta-analysis of published observational studies indicates that physical activity may be associated with reduced risk of esophageal adenocarcinoma. Lifestyle interventions focusing on increasing physical activity may decrease the global burden of EAC. PMID:24886123

To analyze the clinical outcome of concurrent chemoradiotherapy in superficial esophageal cancer patients. We retrospectively analyzed data for 123 patients with superficial esophageal cancer who received external beam radiotherapy without intracavitary brachytherapy plus systemic chemotherapy during 1998-2015. Elective nodal irradiation was not performed. The dosage to planning treatment volume was 60 Gy in 30 fractions. The main outcome measure was overall survival. Patient characteristics were as follows: median age, 66 (41-83) years; male/female ratio, 106/17; squamous cell carcinoma/other, 122/1; cT1a/cT1b, 27/96; cervical esophagus/upper thoracic esophagus/middle thoracic esophagus/lower thoracic esophagus, 7/9/66/41 and concurrent chemoradiotherapy/radiotherapy alone, 100/23. Cisplatin and 5-fluorouracil were the most commonly used agents (85%). At the last follow-up (median 60.5 months), 91 (74%) patients were alive. Complete response was achieved in 116 (94.4%) patients. The 5-year overall survival, progression-free survival and local control rates were 77.0, 46.9 and 62.7%, respectively, similar to that in the elderly patients (P = 0.878, 0.754 and 0.648, respectively). There were 55 failures: 42 local, 10 regional and 3 distant failures. Nine local and seven regional failures developed out-of-field. Thirty-eight local failures (90%) were successfully salvaged, of which 30 (71%) were salvaged via endoscopic removal; only 2 regional failures (20%) were salvaged. Fifteen G3 acute toxicities occurred. One pneumonitis (G3), one pneumothorax (G3) and two pericardial effusion (G2) were the late toxicities observed. There were no G4 toxicities or treatment-related deaths. Concurrent chemoradiotherapy without intracavitary brachytherapy was effective and safe for superficial esophageal cancer, even in elderly patients. © The Author 2017.

2013-04-01

Impairment of esophageal motility is a common finding in patients with gastroesophageal reflux disease (GERD) as reduced lower esophageal sphincter (LES) basal pressure. A very low LES pressure might facilitate the occurrence of more gastroesophageal reflux whereas abnormal esophageal peristalsis may contribute to impaired esophageal clearance after reflux. Evaluate the esophageal motor function of the lower esophageal sphincter and esophageal body in the various forms of gastroesophageal reflux disease. The manometrics records of 268 patients, who had evaluation of the esophageal motility as part of the diagnostic gastroesophageal reflux disease were split into four groups, as follows: 33 patients who had no esophagitis; 92 patients who had erosive esophagitis; 101 patients who had short Barrett's esophagus and 42 patients who had long Barrett's esophagus. The group who had long Barrett's esophagus showed smaller mean LES pressure and higher percentage of marked LES hypotonia; in the distal segment of the esophageal body the this group showed higher percentage of marked hypocontractility of the distal segment (<30 mm Hg); this same group showed higher percentage of esophageal motility disorders. The most intense esophageal motility disorders and lower pressure of lower esophageal sphincter were noted in the group with long Barrett's esophagus. Those with reflux esophagitis and short Barrett's esophagus had esophageal motility impairment, intermediate among patients with esophagitis and long Barrett's esophagus. Patients with typical symptoms of gastroesophageal reflux but without esophagitis by endoscopy study showed no impairment of esophageal motility.

Non-specific esophageal dysmotility with impaired clearance is often present in patients with gastro-esophageal reflux disease (GERD), especially those with erosive disease; however the physio-mechanic basis of esophageal dysfunction is not well defined. Retrospective assessment of patients with erosive reflux disease (ERD; n=20) and endoscopy negative reflux disease (ENRD; n=20) with pathologic acid exposure on pH studies (>4.2% time/24 h) and also healthy controls (n=20) studied by high resolution manometry. Esophageal motility in response to liquid and solid bolus swallows and multiple water swallows (MWS) was analyzed. Peristaltic dysfunction was defined as failed peristalsis, spasm, weak or poorly coordinated esophageal contraction (>3cm break in 30 mmHg isocontour). Peristaltic dysfunction was present in 33% of water swallows in controls, 56% ENRD and 76% ERD respectively (P<0.023 vs controls, P=0.185 vs ENRD). The proportion of effective peristaltic contractions improved with solid compared to liquid bolus in controls (18%vs 33%, P=0.082) and ENRD (22%vs 54%, P=0.046) but not ERD (62%vs 76%, P=0.438). Similarly, MWS was followed by effective peristalsis in 83% of controls and 70% ENRD but only 30% ERD patients (P<0.017 vs controls and P<0.031 vs ENRD). The association between acid exposure and dysmotility was closer for solid than liquid swallows (r=0.52 vs 0.27). Peristaltic dysfunction is common in GERD. ERD patients are characterized by a failure to respond to the physiologic challenge of solid bolus and MWS that is likely also to impair clearance following reflux events and increase exposure to gastric refluxate. © 2011 Blackwell Publishing Ltd.

Background A Stanford University study reported that in asymptomatic GERD patients who were being treated with a proton pump inhibitor (PPI), 50% had pathologic esophageal acid exposure. Aim We considered the possibility that the high prevalence of pathologic esophageal reflux might simply have resulted from calculating acidity as time pH < 4. Methods We calculated integrated acidity and time pH < 4 from the 49 recordings of 24-hour gastric and esophageal pH from the Stanford study as well as from another study of 57 GERD subjects, 26 of whom were treated for 8 days with 20 mg omeprazole or 20 mg rabeprazole in a 2-way crossover fashion. Results The prevalence of pathologic 24-hour esophageal reflux in both studies was significantly higher when measured as time pH < 4 than when measured as integrated acidity. This difference was entirely attributable to a difference between the two measures during the nocturnal period. Nocturnal gastric acid breakthrough was not a useful predictor of pathologic nocturnal esophageal reflux. Conclusion In GERD subjects treated with a PPI, measuring time esophageal pH < 4 will significantly overestimate the prevalence of pathologic esophageal acid exposure over 24 hours and during the nocturnal period.

Intramural metastasis (IM) of esophageal cancer is defined as metastasis from a primary lesion to the esophageal wall without intraepithelial cancer extension. Esophageal cancer with IM is more common and such cases indicate a poor prognosis. In esophageal surgery, if curative resection is possible, the complete removal of both primary tumor and associated IMs is required. Therefore, accurate diagnosis of IMs in esophageal cancer prior to surgery is of particular importance. Multiphoton microscopy (MPM) with subcellular resolution is well-suited for deep tissue imaging since many endogenous fluorophores of fresh biological tissues are excited through two-photon excited fluorescence (TPEF) and second harmonic generation (SHG). Here, a study to identify IM in fresh tissue section using MPM is reported. In this study, the morphological and spectral differences between IM and surrounding tissue are described. These results show that MPM has the ability to accurately identify IM in esophageal tissues. With improvement of the penetration depth of MPM and the development of multiphton microendoscope, MPM may be a promising imaging technique for preoperative diagnosis of IMs in esophageal cancer in the future.

The purposes of this study were to assess the esophageal clearance of a radioisotopic bolus in patients with symptoms of reflux and evaluate the impact of manometric abnormalities on scintigraphic esophageal transit. Esophageal clearance was assessed in a supine position and indicated by the retained radioactivity in the esophagus at 10, 20, 30 and 40 s after the ingestion of a liquid bolus labeled with 2 mCi 99 mTc-SC. The study included 214 consecutive patients with symptoms of reflux and 11 normal controls. The results were compared to the motility findings detected on manometry performed on a separate occasion. Esophageal manometry was normal in 93 patients. Nonspecific esophageal motor disorders were identified in 121 patients and were classified into: 'predominantly nonpropagated activity', 'predominantly low-amplitude peristaltic contractions' and 'miscellaneous disorders' diagnosed in 27, 47 and 47 patients, respectively. The radionuclide clearance was significantly delayed in the overall group of patients compared with that of normal controls (P < 0.001); in patients with reflux symptoms and nonspecific esophageal motor disorders compared with patients with reflux symptoms and 'normal manometry' (P < 0.01 at 20 s); and in patients with reflux symptoms and 'normal manometry' compared with the control group (P < 0.01 at 20 s). Abnormal radioisotope clearances were detected in 88% of patients with 'predominantly nonpropagated activity', in 70% of patients with 'predominantly low-amplitude peristaltic contractions' and in 57% of patients with 'miscellaneous disorders'. Radioisotopic esophageal clearance abnormalities are frequently observed in patients with reflux symptoms and are more likely to be associated to hypomotility disorders, i.e. nonpropagated motor activity or low-amplitude contractions.

Although a high incidence of bacteremia after esophageal endoscopic procedures has been reported, the incidence of bacteremia associated with esophageal endoscopic submucosal dissection (ESD) remains unknown. Therefore, we investigated the incidence of bacteremia associated with esophageal ESD. From April 2013 to March 2014, patients who underwent esophageal ESD were enrolled prospectively. Two sets of blood cultures were collected from patients at the following time points: (1) immediately after ESD; (2) the next morning; and (3) when fever ≥38 °C was present after ESD. A total of 424 blood culture sets were collected from 101 patients. Six patients had positive blood cultures immediately after ESD (4 %, 7/202 sets). Another patient had a positive blood culture the next morning (0.5 %, 1/202 sets). Ten patients (10 %) developed a post-ESD fever ≥38 °C, and blood cultures from these patients were all negative (0/20 sets). The seven patients with positive blood cultures had no post-ESD fever or infectious symptoms. Growth of Bacteroides thetaiotaomicron was only observed in one patient (1 %) with positive blood cultures immediately after ESD, and this patient was diagnosed with transient bacteremia. The other six patients were considered to have contaminants in their blood cultures. Thus, the incidence of bacteremia after esophageal ESD was 1 % [95 % confidence interval (CI) 0-5 %]. No patient had infectious symptoms, and none required antibiotics after ESD. The incidence of bacteremia after esophageal ESD was low and post-ESD fever was not associated with bacteremia. We conclude that use of routine prophylactic antibiotics to patients undergoing esophageal ESD is unnecessary. UMIN000012908.

The Tumor Microenvironment in Esophageal Cancer

2016-01-01

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.

Several studies have reported the importance of dietary factors in the development of esophageal cancer. The purpose of the present study was to evaluate the effects of several common dietary factors on the risk of squamous cell carcinoma of the esophagus in a Taiwanese population. The association between diet and esophageal cancer was examined in 284 male patients and 480 male controls, who were recruited during 6 year period. Consumption of preserved and overheated foods was found to be associated with increased risk of esophageal cancer, whereas intake of fresh fruits, vegetables, and tea was inversely associated with this risk. Men who consumed fermented bean products, salted food and preserved/pickled vegetables more than once a week after age 40 years had a 3.4-fold risk (95% confidence interval (CI): 1.9-6.2), 2.3-fold risk (95%CI: 1.2-4.2), and 2.5-fold risk (95%CI: 1.3-4.5), respectively, compared to men eating these items less than once a week. It was further found that these preserved foods were more strongly associated with esophageal cancer among men who consumed fruit less than once per day than those who consumed fruits one or more times per day. These results suggest that a high intake of preserved foods and overheated drinks might increase the risk of esophageal cancer, and intake of fruit, vegetables, and tea might be negatively associated with risk of esophageal cancer. The results also suggest that diet is an important factor in the development of esophageal cancer in Taiwan.

Peroral endoscopic myotomy (POEM) has been introduced as a novel endoscopic treatment for achalasia. The aim of this work is to assess the changes in esophageal motility caused by POEM in patients with achalasia. Forty-one patients with achalasia underwent POEM from September 2012 to November 2014. Esophageal motility of all patients was evaluated preoperatively and 1 month after POEM utilizing high-resolution manometry, which was performed with ten water swallows, ten steamed bread swallows, and multiple rapid swallows (MRS). In single swallows, including liquid swallows and bread swallows, all the parameters of lower esophagus sphincter resting pressure (LESP), 4-s integrated relaxation pressure (4sIRP), and intra-bolus pressure (IBP) were decreased between pre- and post-POEM patients (all p < 0.05). Postoperatively, the trend of distal contractile integral (DCI) and distal esophageal peristaltic amplitude declined in subtype II and subtype III (subtype II: p < 0.05; subtype III: p > 0.05), but increased in subtype I (subtype I: p > 0.05). In liquid swallows, the Eckardt score of subtype II patients decreased with DCI, and distal esophageal peristaltic amplitude after POEM was significantly lower compared with those showing increased values of those two parameters (p < 0.05). In MRS, the rate of LES relaxation increased from 66.67 to 95.24%, but without normal response in all achalasia patients. POEM reduces LES pressure in achalasia, and partly restores esophageal motility. POEM displayed varying effect on esophageal motility in patients with different patterns of swallowing. In addition, the changes in parameters associated with esophageal peristalsis correlated with decreases in Eckardt score.

Esophageal function testing: Billing and coding update.

Esophageal function testing is being increasingly utilized in diagnosis and management of esophageal disorders. There have been several recent technological advances in the field to allow practitioners the ability to more accurately assess and treat such conditions, but there has been a relative lack of education in the literature regarding the associated Common Procedural Terminology (CPT) codes and methods of reimbursement. This review, commissioned and supported by the American Neurogastroenterology and Motility Society Council, aims to summarize each of the CPT codes for esophageal function testing and show the trends of associated reimbursement, as well as recommend coding methods in a practical context. We also aim to encourage many of these codes to be reviewed on a gastrointestinal (GI) societal level, by providing evidence of both discrepancies in coding definitions and inadequate reimbursement in this new era of esophageal function testing. © 2017 John Wiley & Sons Ltd.

To assess the association between single nucleotide polymorphisms (SNPs) of base-excision repair genes and clinical outcomes, the roles of genetic variants of 3 selected genes-flap structure-specific endonuclease 1 (FEN1), 8-hydroxyguanine DNA glycosylase (hOGG1), and nei endonuclease VIII-like 1 (NEIL1)--were investigated in radiation-induced esophageal toxicity (RIET), radiation pneumonitis (RP), and overall survival (OS) after radio(chemo)therapy in patients with esophageal squamous cell carcinoma (ESCC). NEIL1 reference SNP 4462560 (rs4462560) and rs7402844, hOGG1 rs1052133 and rs293795, and FEN1 rs4246215 and rs174538 were genotyped in 187 patients with ESCC who received definitive radiotherapy with or without chemotherapy. Kaplan-Meier cumulative probabilities and Cox proportional hazards regression models were used to assess the effect of the genotypes on the risk of RIET, RP, and OS. The authors observed that patients who had the NEIL1 rs4462560 GC/CC genotype had a statistically significantly lower risk of both grade ≥ 2 acute radiation-induced esophageal toxicity (RIET) (adjusted hazard ratio [HR], 0.421; 95% confidence interval [CI], 0.207-0.856; P = .017) and grade ≥ 2 acute radiation pneumonitis (RP) (adjusted HR, 0.392; 95% CI, 0.163-0.946; P = .037) compared with patients who had the GG genotype, but the genotype did not affect OS (adjusted HR, 0.778; 95% CI, 0.471-1.284; P = .326). There were no significant findings for other the SNPs under investigation. The NEIL1 rs4462560 SNP may serve as a predictor of acute RIET and RP risk but not of OS. Larger prospective studies are needed to validate these findings. © 2013 American Cancer Society.

AIM: To investigate the prevalence and the clinical characteristics of Asian patients with eosinophilic esophagitis. METHODS: We conducted a systematic search of the PubMed and Web of Science databases for original studies, case series, and individual case reports of eosinophilic esophagitis in Asian countries published from January 1980 to January 2015. We found 66 and 80 articles in the PubMed and Web of Science databases, respectively; 24 duplicate articles were removed. After excluding animal studies, articles not written in English, and meeting abstracts, 25 articles containing 217 patients were selected for analysis. RESULTS: Sample size-weighted mean values were determined for all pooled prevalence data and clinical characteristics. The mean age of the adult patients with eosinophilic esophagitis was approximately 50 years, and 73% of these patients were male. They frequently presented with allergic diseases including bronchial asthma, allergic rhinitis, food allergy, and atopic dermatitis. Bronchial asthma was the most frequent comorbid allergic disease, occurring in 24% of patients with eosinophilic esophagitis. Dysphagia was the primary symptom reported; 44% of the patients complained of dysphagia. Although laboratory blood tests are not adequately sensitive for an accurate diagnosis of eosinophilic esophagitis, endoscopic examinations revealed abnormal findings typical of this disease, including longitudinal furrows and concentric rings, in 82% of the cases. One-third of the cases responded to proton pump inhibitor administration. CONCLUSION: The characteristics of eosinophilic esophagitis in Asian patients were similar to those reported in Western patients, indicating that this disease displays a similar pathogenesis between Western and Asian patients.

Progestin and adipoQ receptor family member III (PAQR3), a member of the PAQR family, is frequently downregulated in different types of human cancer. However, its expression and functions in esophageal cancer are still unknown. This study aimed to explore the expression of PAQR3 in esophageal cancer cell lines and to investigate the role of PAQR3 in the development of esophageal cancer. Our data showed that PAQR3 is expressed in low amounts in human esophageal cancer cell lines. Overexpression of PAQR3 significantly suppressed the proliferation, migration, and invasion of esophageal cancer cells. In addition, overexpression of PAQR3 downregulated the protein expression levels of RAF1, p-MEK1, and p-ERK1/2 in esophageal cancer cells. Furthermore, overexpression of PAQR3 attenuated the tumor growth in a tumor xenograft model. In conclusion, we demonstrated that overexpression of PAQR3 suppresses cell proliferation, migration, and invasion in esophageal cancer in vitro and in vivo. Therefore, PAQR3 may act as a therapeutic target for human esophageal cancer.

Eosinophilic esophagitis (EoE) is a chronic allergic (immune-mediated) disease that leads to esophageal dysfunction and feeding disorders in children. Foods, and possibly environmental triggers, cause an inflammatory response in the esophagus, leading to esophageal inflammation, eosinophilic infiltration, and esophageal dysmotility, which may progress to dysphagia, food impaction, and esophageal stricture. Endoscopy with biopsy and histologic evaluation is currently the only method to diagnose EoE. Once diagnosed with EoE, children undergo follow-up endoscopy after therapy initiation and adjustments to ensure remission. Furthermore, children with food impactions or strictures may require endoscopic intervention such as foreign body removal and/or esophageal dilation. Copyright © 2016 Elsevier Inc.

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

Single nucleotide polymorphisms (SNPs) in TERT may be associated with susceptibility to esophageal cancer. In this study, we analyzed the association between TERT SNPs and risk of esophageal cancer in 386 esophageal cancer patients and 495 healthy subjects from the Xi'an area of China. Of the four SNPs examined, rs10069690 and rs2242652 were correlated with esophageal cancer risk. Additionally, after adjusting for age and gender, the "Trs10069690Ars2242652", "Trs10069690Grs2242652" haplotypes were associated with an increased risk of esophageal cancer, while the and "Crs10069690Grs2242652" haplotype was associated with a decreased risk of esophageal cancer. These findings suggest that TERT polymorphisms may contribute to the development of esophageal cancer.

Mixed connective tissue disease is a systemic inflammatory disorder that results in both pulmonary and esophageal manifestations. We sought to evaluate the relationship between esophageal dysfunction and interstitial lung disease in patients with mixed connective tissue disease. We correlated the pulmonary function data and the high-resolution computed tomography findings of interstitial lung disease with the results of esophageal evaluation in manometry, 24-hour intraesophageal pH measurements, and the presence of esophageal dilatation on computed tomography scan. Fifty consecutive patients with mixed connective tissue disease, according to Kasukawa's classification criteria, were included in this prospective study. High-resolution computed tomography parenchymal abnormalities were present in 39 of 50 patients. Esophageal dilatation, gastroesophageal reflux, and esophageal motor impairment were also very prevalent (28 of 50, 18 of 36, and 30 of 36, respectively). The presence of interstitial lung disease on computed tomography was significantly higher among patients with esophageal dilatation (92% vs. 45%; p<0.01) and among patients with severe motor dysfunction (90% vs. 35%; p<0.001). Although we were not able to prove a causal relationship between esophageal and pulmonary involvement, our series revealed a strong association between esophageal motor dysfunction and interstitial lung disease in patients with mixed connective tissue disease.

The function and structure of the gastro-esophageal junction (GEJ) determine its efficacy as a reflux barrier. This study presents a novel methodology for the quantitative assessment of GEJ and proximal gastric morphology from magnetic resonance (MR) imaging. Based on this data we propose a new conceptualization of the hypothesis that a flap valve mechanism contributes to reflux protection. 3D models of the GEJ and proximal stomach were reconstructed from MR images in 12 healthy volunteers during respiration and on eating a test meal to maximum satiation. A rotating plane analysis measured the gastro-esophageal insertion angle and span of contact. An ellipsoid fit provided quantitative assessment of gastric shape and orientation relative to a fixed anatomical reference point. Position of the esophageal insertion on the 'gastric ellipse' was noted. An ellipsoid-cylinder model was designed to analyze the relationships among parameters describing the GEJ morphology. The insertion angle became more acute on expiration, but did not change with meal ingestion. In contrast the span of contact did not vary with respiration, but increased with gastric filling. Changes in gastric morphology with distension further augmented the span of gastro-esophageal contact in almost 70% of the studies. Novel MR imaging and biophysical analysis of the GEJ and proximal stomach provide a quantitative description of structures contributing to the reflux barrier. Changes in these parameters during respiration and on eating support the hypothesis that structural components of a functional 'flap valve' like mechanism contribute to reflux protection. © 2012 Blackwell Publishing Ltd.

Nowadays the level of early and late complications after the operations for esophageal corrosive strictures such as esophago-organ anastomotic leak, development of infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive stricture development etc. remains rather high. Besides, postoperative mortality rate is high as well - 3.5-30 %. For that reason, an experimental model of esophageal stricture was suggested and ultrastructural mucosal changes in the stricture itself were studied to elaborate the unified pathogenic approach in treatment of esophageal stricture and improvement of its results. The aim of our work was to study the dynamics of ultrastructural changes both in normal esophageal walls and in third degree esophageal stricture Materials and Methods: The experiment was carried out on white male rats weighting 250-300 grams, to whom the third degree esophageal stricture model was created. After layer-by-layer incision of anterior abdominal wall abdominal portion of the esophagus was completely ligated (10 rats). In the control group (6 rats) anterior abdominal wall was opened with its subsequent layered closure. The animals were withdrawn from the experiment on the third day by ketamine overdose, and the samples were taken for ultrastructural study. Electron microscopic study of submicroscopic organization of basal, prickle, superficial epithelial cells in stratified non-squamous epithelium, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer was carried out. Nuclear membrane, membranes of mitochondria, endoplasmic reticulum and cytoplasmic Golgi complex were found to be subjected to focal lysis. The third degree esophageal stricture caused destructive lesions in ultrastructural architectonics of stratified non-squamous epithelium cells, smooth myocytes of muscle plate and contractile elements in esophageal muscular layer of rats. Thus, catabolic processes leading to organelle disintegration

Many kinetochore proteins have been shown to be associated with human cancers. The aim of the present study was to clarify the expression of Centromere protein H (CENP-H), one of the fundamental components of the human active kinetochore, in esophageal carcinoma and its correlation with clinicopathological features. We examined the expression of CENP-H in immortalized esophageal epithelial cells as well as in esophageal carcinoma cells, and in 12 cases of esophageal carcinoma tissues and the paired normal esophageal tissues by RT-PCR and Western blot analysis. In addition, we analyzed CENP-H protein expression in 177 clinicopathologically characterized esophageal carcinoma cases by immunohistochemistry. Statistical analyses were applied to test for prognostic and diagnostic associations. The level of CENP-H mRNA and protein were higher in the immortalized cells, cancer cell lines and most cancer tissues than in normal control tissues. Immunohistochemistry showed that CENP-H was expressed in 127 of 171 ESCC cases (74.3%) and in 3 of 6 esophageal adenocarcinoma cases (50%). Statistical analysis of ESCC cases showed that there was a significant difference of CENP-H expression in patients categorized according to gender (P = 0.013), stage (P = 0.023) and T classification (P = 0.019). Patients with lower CENP-H expression had longer overall survival time than those with higher CENP-H expression. Multivariate analysis suggested that CENP-H expression was an independent prognostic marker for esophageal carcinoma patients. A prognostic value of CENP-H was also found in the subgroup of T3 approximately T4 and N0 tumor classification. Our results suggest that CENP-H protein is a valuable marker of esophageal carcinoma progression. CENP-H might be used as a valuable prognostic marker for esophageal carcinoma patients.

Herein is described a unique case of esophageal cancer mimicking acantholytic squamous cell carcinoma (SCC). The patient succumbed to the disease within one month of diagnosis. Autopsy revealed a 10-cm esophageal tumor, characterized by prominent acantholysis-like areas composed of discohesive cancer cells, along with nested growth of SCC. These discohesive cancer cells focally exhibited pagetoid extension into adjacent esophageal epithelium, comprised ~60% of the esophageal tumor volume and had widely metastasized to the lungs, chest wall, liver, spleen, right adrenal gland, bones and lymph nodes. No metastases of SCC were observed. SCC cells were immunohistochemically positive for keratin 5/6 and E-cadherin and were negative for mucin and carcinoembryonic antigen (CEA). However, the discohesive cancer cells exhibited negativity for keratin 5/6, positivity for mucin and CEA, and diminished or no immunostaining for E-cadherin. Thus, these discohesive cells represented true adenocarcinomatous differentiation rather than acantholytic SCC cells. It was concluded that this tumor was an esophageal adenosquamous carcinoma with ‘pseudo’-acantholytic adenocarcinoma components, which should be considered as a rare but distinctive type of aggressive cancer.

With the recent availability of removable esophageal stents, endoscopic stenting has been utilized to treat refractory benign esophageal strictures (RBES). The objective of this study was to review the feasibility and effectiveness of removable esophageal stents to treat RBES. Patients who received removable esophageal stents for the treatment of RBES at the institution between 2004-2010 using its stent implantation logs and endoscopic database were retrospectively identified. Patient demographics, stricture etiology and location, stent and procedure characteristics, and clinical outcomes were obtained. Twenty-five patients with a mean age of 70 (72% male) underwent initial stent placement; 24 were successful. Overall clinical success was achieved in five of the 19 patients (26%) ultimately undergoing stent removal. RBES etiologies included anastomotic (13), radiation (5), peptic (3), chemotherapy (1), scleroderma (1), and unknown (2). Alimaxx-E (Merit-Endotek, South Jordan, UT, USA) stents were placed in 20 patients and Polyflex (Boston Scientific, Natick, MA, USA) stents were used in five patients. Immediate complications included failed deployment (1) and chest pain (7). Five patients died prior to stent removal. Stent migration was found in 53% (10/19) of patients who underwent stent removal: nine required additional therapy and one had symptom resolution. Out of the nine patients without stent migration, five required additional therapy and four had symptom resolution. Although placement of removable esophageal stents for RBES is technically feasible, it is frequently complicated by stent migration and chest pain. In addition, few patients achieved long-term stricture resolution after initial stenting. In this study, most patients ultimately required repeated stenting and/or dilations to maintain relief of dysphagia. © 2012 Copyright the Authors.

The Chicago Classification of esophageal motility was developed to facilitate the interpretation of clinical high resolution esophageal pressure topography (EPT) studies, concurrent with the widespread adoption of this technology into clinical practice. The Chicago Classification has been an evolutionary process, molded first by published evidence pertinent to the clinical interpretation of high resolution manometry (HRM) studies and secondarily by group experience when suitable evidence is lacking. This publication summarizes the state of our knowledge as of the most recent meeting of the International High Resolution Manometry Working Group in Ascona, Switzerland in April 2011. The prior iteration of the Chicago Classification was updated through a process of literature analysis and discussion. The major changes in this document from the prior iteration are largely attributable to research studies published since the prior iteration, in many cases research conducted in response to prior deliberations of the International High Resolution Manometry Working Group. The classification now includes criteria for subtyping achalasia, EGJ outflow obstruction, motility disorders not observed in normal subjects (Distal esophageal spasm, Hypercontractile esophagus, and Absent peristalsis), and statistically defined peristaltic abnormalities (Weak peristalsis, Frequent failed peristalsis, Rapid contractions with normal latency, and Hypertensive peristalsis). The Chicago Classification is an algorithmic scheme for diagnosis of esophageal motility disorders from clinical EPT studies. Moving forward, we anticipate continuing this process with increased emphasis placed on natural history studies and outcome data based on the classification. © 2012 Blackwell Publishing Ltd.

2014-11-01

The aim of the present study was to evaluate the efficacy and short-term safety of topical mitomycin-C, an antifibrotic agent, in preventing the recurrence of anastomotic strictures after surgical repair of esophageal atresia (EA). We retrospectively reviewed the medical records of patients with recurrent anastomotic strictures after EA surgery who underwent at least 3 esophageal dilations. We compared the outcome (ie, resolution of the stricture) of the group that received topical mitomycin-C treatment with endoscopic esophageal dilation with a historical cohort treated by dilations alone. A total of 11 children received mitomycin-C concurrently with endoscopic dilations. After a median follow-up of 33 months (range 18-72), and a mean number of 5.4 dilations per patient (range 3-11), 8 of 11 patients achieved a resolution of their strictures, 2 patients remained with stenosis, and 1 patient needed a surgical correction. In the control group, 10 patients required an average of 3.7 (range 3-7) total dilations. After a follow-up of 125 months (range 35-266) after the last dilation, strictures in 9 of 10 children disappeared and the remaining patient was symptom free. No dysplasia related to mitomycin-C was demonstrated. There is no benefit in the resolution of the stricture when adding mitomycin-C treatment compared with repeated esophageal dilations alone in historical controls. Further randomized controlled studies and a short- and long-term evaluation of safety are needed.

To report oncological outcomes and toxicity rates, of definitive platin-based chemoradiadiationtherapy (CRT) in the management of proximal esophageal cancer. We retrospectively reviewed the medical records of patients with cT1-4 cN0-3 cM0 cervical esophageal cancer (CEC) (defined as tumors located below the inferior border of the cricoid cartilage, down to 22 cm from the incisors) treated between 2004 and 2013 with platin-based definitive CRT in four Swiss institutions. Acute and chronic toxicities were retrospectively scored using the National Cancer Institute's Common Terminology Criteria for Adverse Events, version 4.0 (CTCAE-NCI v.4.0). Primary endpoint was loco-regional control (LRC). We also evaluated overall survival (OS) and disease-free survival (DFS) rates. The influence of patient- and treatment related features have been calculated using the Log-rank test and multivariate Cox proportional hazards model. We enrolled a total of 55 patients. Median time interval from diagnosis to CRT was 78 days (6-178 days). Median radiation dose was 56Gy (28-72Gy). Induction chemotherapy (ICHT) was delivered in 58% of patients. With a median follow up of 34 months (6-110months), actuarial 3-year LRC, DFS and OS were 52% (95% CI: 37-67%), 35% (95% CI: 22-50%) and 52% (95% CI: 37-67%), respectively. Acute toxicities (dysphagia, pain, skin-toxicity) ranged from grade 0 - 4 without significant dose-dependent differences. On univariable analyses, the only significant prognostic factor for LRC was the time interval > 78 days from diagnosis to CRT. On multivariable analysis, total radiation dose >56Gy (p <0.006) and ICHT (p < 0.004) were statistically significant positive predictive factors influencing DFS and OS. Definitive CRT is a reliable therapeutic option for proximal esophageal cancer, with acceptable treatment related toxicities. Higher doses and ICHT may improve OS and DFS and. These findings need to be confirmed in further prospective studies.

Esophageal cancer rates have continued to rise in the Western World. Esophageal cancer will be responsible for an estimated 15,450 deaths in the United States in 2014 alone. Esophageal resection with or without preoperative therapy remains the mainstay of treatment. Advances in surgical technique and perioperative care have improved short-term outcomes considerably by decreasing operative mortality. Despite these advances though, esophagectomy remains a procedure associated with considerable morbidity from a wide range of complications. Prompt recognition and treatment of complications can lower overall morbidity and mortality. Unfortunately, long-term outcomes remain poor as the vast majority of patients present with loco-regionally advanced or metastatic disease. Surgery by itself provides poor loco-regional control and fails to address micrometastatic disease. Neoadjuvant chemotherapy or chemoradiation provides a modest survival advantage compared to surgical resection alone. Future gains in understanding the molecular biology of esophageal cancer will hopefully lead to improved therapeutics and resultant outcomes. © 2014 Wiley Periodicals, Inc.

Increased esophageal sensitivity and impaired mucosal integrity have both been described in patients with gastroesophageal reflux disease, but the relationship between hypersensitivity and mucosal integrity is unclear. The aim of the present study was to investigate acid sensitivity in patients with erosive and nonerosive reflux disease and control subjects to determine the relation with functional esophageal mucosal integrity changes as well as to investigate cellular mechanisms of impaired mucosal integrity in these patients. In this prospective experimental study, 12 patients with nonerosive reflux disease, 12 patients with esophagitis grade A or B, and 11 healthy control subjects underwent an acid perfusion test and upper endoscopy. Mucosal integrity was measured during endoscopy by electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance, transepithelial permeability and gene expression of tight junction proteins and filaggrin. Patients with nonerosive reflux disease and esophagitis were more sensitive to acid perfusion compared with control subjects, having a shorter time to perception of heartburn and higher perceived intensity of heartburn. In reflux patients, enhanced acid sensitivity was associated with impairment of in vivo and vitro esophageal mucosal integrity. Mucosal integrity was significantly impaired in patients with esophagitis, displaying higher transepithelial permeability and lower extracellular impedance. Although no significant differences in the expression of tight junction proteins were found in biopsies among patient groups, mucosal integrity parameters in reflux patients correlated negatively with the expression of filaggrin. In conclusion, sensitivity to acid is enhanced in patients with gastroesophageal reflux disease, irrespective of the presence of erosions, and is associated with impaired esophageal mucosal integrity.

To assess whether corpus gastritis due to Helicobacter pylori protects against erosive esophagitis in an area with high prevalence of H. pylori infection. Biopsies obtained from gastric corpus and antrum in 151 patients with symptoms of gastroesophageal reflux disease were studied for presence of H. pylori and endoscopic evidence of gastritis. Presence and grade of esophagitis at endoscopy was recorded. Fifty-four (36%) patients had endoscopic esophagitis. Patients with severe esophagitis (>or= grade II) less often had active gastritis (15/45 vs. 55/98; p=0.02) and had a lower density of H. pylori (p=0.0003) than those without esophagitis. Active corpus gastritis due to H. pylori infection may protect against erosive esophagitis in patients with gastroesophageal reflux disease in the Middle East.

The esophagus functions to transport swallowed fluids and food from the pharynx to the stomach. The esophageal muscles governing bolus transport comprise circular striated muscle of the proximal esophagus and circular smooth muscle of the distal esophagus. Longitudinal smooth muscle contraction provides a mechanical advantage to bolus transit during circular smooth muscle contraction. Esophageal striated muscle is directly controlled by neural circuits originating in the central nervous system, resulting in coordinated contractions. In contrast, the esophageal smooth muscle is controlled by enteric circuits modulated by extrinsic central neural connections resulting in neural relaxation and contraction. The esophageal muscles are modulated by sensory information arising from within the lumen. Contraction or relaxation, which changes the diameter of the lumen, alters the intraluminal pressure and ultimately inhibits or promotes flow of content. This relationship that exists between the changes in diameter and concurrent changes in intraluminal pressure has been used previously to identify the "mechanical states" of the circular muscle; that is when the muscles are passively or actively, relaxing or contracting. Detecting these changes in the mechanical state of the muscle has been difficult and as the current interpretation of esophageal motility is based largely upon pressure measurement (manometry), subtle changes in the muscle function during peristalsis can be missed. We hypothesized that quantification of mechanical states of the esophageal circular muscles and the pressure-diameter properties that define them, would allow objective characterization of the mechanisms that govern esophageal peristalsis. To achieve this we analyzed barium swallows captured by simultaneous videofluoroscopy and pressure with impedance recording. From these data we demonstrated that intraluminal impedance measurements could be used to determine changes in the internal diameter of

Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identify those patients at risk for bleeding from varices. However, this practice may not be cost effective as large esophageal varices are seen only in 9-36% of these patients. The aim of this study was to determine whether clinical variables were predictive of the presence of large esophageal varices. This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during an evaluation for liver transplantation at three different centers and who had not previously bled from varices. A multivariate model was derived on the combined cohort using logistic regression. Three hundred forty-six patients were eligible for the study. The prevalence of large esophageal varices was 20%. On multivariate analysis, splenomegaly detected by computed tomographic scan (odds ratio: 4.3; 95% confidence interval: 1.6-11.5) or by physical examination (odds ratio: 2.0; 95% confidence interval: 1.1-3.8), and low platelet count were independent predictors of large esophageal varices. On the basis of these variables, cirrhotics were stratified into high- and low-risk groups for the presence of large esophageal varices. Patients with a platelet count of > or = 88,000/mm3 (median value) and no splenomegaly by physical examination had a risk of large esophageal varices of 7.2%. Those with splenomegaly or platelet count < 88,000/mm3 had a risk of large esophageal varices of 28% (p < 0.0001). Our data show that clinical predictors could be used to stratify cirrhotic patients for the risk of large esophageal varices and such stratification could be used to improve the cost effectiveness of screening endoscopy.

To describe diurnal variations of esophageal motor function in children using combined ambulatory 24-hour esophageal manometry and continuous intraluminal pH measurement (MP24). Medical records of all patients referred for the performance of MP24 from 1995 to 2002 at a tertiary care center were reviewed. Patients were selected retrospectively for this study using the following inclusion criteria: (1) no dysphagia, (2) normal upper gastrointestinal barium radiograph, (3) normal esophagogastroduodenoscopy and biopsies, (4) normal stationary esophageal manometry, (5) normal esophageal pH probe, and (6) no gastrointestinal pathology appearing after long-term follow-up. Data from the MP24 of these children were retrospectively analyzed for differences between meal, upright, and supine periods using nonparametric univariate analysis. One hundred twenty-three children had MP24 during the study period. Eleven met the criteria for normality and were included. Their mean age was 12.4 +/- 1.5 years. The number of contractions/minute in the upper, middle, and lower esophageal body differed significantly during meals and in the upright and supine periods (P < 0.01). A significant increase in motor activity occurred during meals (P < 0.01). There was less motor activity observed in the supine position than in the upright position (P < 0.01). There were significant differences in effective (P < 0.05) and total propagated peristalsis among the meal, upright, and supine periods (P < 0.01), with the largest percentage of propagated contractions observed during meals. This study provides the first information on prolonged esophageal motor activity in pediatric patients without esophageal disease. MP24 in children demonstrates significant diurnal variations in esophageal motor function that is similar to the findings in studies of healthy adults.

Quantifying the mechanical properties of the esophageal wall is crucial to understanding impairments of trans-esophageal flow characteristic of several esophageal diseases. However, these data are unavailable owing to technological limitations of current clinical diagnostic instruments that instead display esophageal luminal cross sectional area based on intraluminal impedance change. In this work, we developed an esophageal model to predict bolus flow and the wall property based on clinical measurements. The model used the constraint-based immersed-boundary method developed previously by our group. Specifically, we first approximate the time-dependent wall geometry based on impedance planimetry data on luminal cross sectional area. We then fed these along with pressure data into the model and computed wall tension based on simulated pressure and flow fields, and the material property based on the strain-stress relationship. As examples, we applied this model to augment FLIP (Functional Luminal Imaging Probe) measurements in three clinical cases: a normal subject, achalasia, and eosinophilic esophagitis (EoE). Our findings suggest that the wall stiffness was greatest in the EoE case, followed by the achalasia case, and then the normal. This is supported by NIH Grant R01 DK56033 and R01 DK079902.

Introduction Esophageal cancer is an extremely aggressive neoplasm, diagnosed in about 17,000 Americans every year with a mortality rate of more than 80% within five years and a median overall survival of just 13 months. For decades, the go-to regimen for esophageal cancer patients has been the use of taxane and platinum-based chemotherapy regimens, which has yielded the field’s most dire survival statistics. Areas covered Combination immunotherapy and a more robust molecular diagnostic platform for esophageal tumors could improve patient management strategies and potentially extend lives beyond the current survival figures. Analyzing a panel of biomarkers including those affiliated with taxane and platinum resistance (ERCC1 and TUBB3) as well as immunotherapy effectiveness (PD-L1) would provide oncologists more information on how to optimize first-line therapy for esophageal cancer. Expert commentary Of the 12 FDA-approved therapies in esophageal cancer, zero target the genome. A majority of the approved drugs either target or are effected by proteomic expression. Therefore, a broader understanding of diagnostic biomarkers could give more clarity and direction in treating esophageal cancer in concert with a greater use of immunotherapy. PMID:27838937

Hypnotherapy for Esophageal Disorders.

PubMed

Riehl, Megan E; Keefer, Laurie

2015-07-01

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.

Abnormal telomere length is widely reported in various human cancers, and it is considered to be an important hallmark of cancer. However, there is remarkably little consensus on the value of telomere length in the prognostic evaluation of esophageal cancers. Here, we attempted to determine the association of variable telomere length with clinical outcome of esophageal cancer patients. Using real-time quantitative PCR, we examined relative telomere lengths (RTL) in a cohort of esophageal cancer and normal esophageal tissues, and statistically investigated the association between RTL and clinical outcomes of esophageal cancer patients. The majority of esophageal cancers in this study had longer RTLs as compared to adjacent non-tumor tissues. Enhanced tumor RTL was associated with smoking habit, poor differentiation, advanced tumor stage, lymph node metastasis and cancer related death. In particular, a close relationship between longer RTL and poor survival was fully demonstrated by using cox regression and Kaplan-Maier survival curves. We found frequent telomere elongation in esophageal cancer tissues, and demonstrated longer RTL may be an independent poor prognostic factor for esophageal cancer patients.

Primary biliary cirrhosis is associated with other autoimmune diseases including Sjögren's syndrome, and scleroderma. Esophageal dysmotility is well known in scleroderma, and Sjögren's syndrome. The aim of this study is to investigate whether any esophageal motor dysfunction exists in patients with primary biliary cirrhosis. The study was performed in 37 patients (36 women, mean age: 56.29 ± 10.01 years) who met diagnostic criteria for primary biliary cirrhosis. Thirty-seven functional dyspepsia patients, were also included as a control group. Patients entering the study were asked to complete a symptom questionnaire. Distal esophageal contraction amplitude, and lower esophageal sphincter resting pressure were assessed. Manometric findings in primary biliary cirrhosis patients vs. controls were as follows: Median lower esophageal sphincter resting pressure (mmHg): (24 vs 20, p=0.033); median esophageal contraction amplitude (mmHg): (71 vs 56, p=0.050); mean lower esophageal sphincter relaxation duration (sc, x ± SD): (6.10 ± 1.18 vs 8.29 ± 1.92, p<0.001); and median lower esophageal sphincter relaxation (%) (96 vs 98, p=0.019); respectively. No significant differences were evident in median peak velocity (sc) (3.20 vs 3.02, p=0.778) between patients with primary biliary cirrhosis and the functional dyspepsia patients. Esophageal dysmotility was found in 17 (45.9%) primary biliary cirrhosis patients (non-specific esophageal motor disorder in ten patients, hypomotility of esophagus in five patients, nutcracker esophagus in one patient and hypertensive lower esophageal sphincter in one patient). Esophageal dysmotility was detected in 45.9% of patients. The study suggests that subclinic esophageal dysmotility is frequent in patients with primary biliary cirrhosis. Crown Copyright © 2014.

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.

Esophageal cancer is one of the most common malignancies worldwide. DACT2 is frequently methylated in human lung, hepatic, gastric and thyroid cancers. The methylation status and function of DACT2 remain to be elucidated in human esophageal cancer. Ten esophageal cancer cell lines, 42 cases of dysplasia and 126 cases of primary esophageal cancer samples were analyzed in this study. The expression of DACT2 was detected in YES2 cells, while reduced DACT2 expression levels were found in TE8 and KYSE70 cells, and complete loss of DACT2 expression was found in KYSE30, KYSE140, KYSE150, KYSE410, KYSE450, TE3 and TE7 cells. Loss of expression or reduced expression of DACT2 correlated with promoter region hypermethylation in esophageal cancer cells. Restoration of DACT2 expression was induced by 5-aza-2′-deoxycytidine. In human primary esophageal squamous carcinoma, 69% (87/126) of samples were methylated. Methylation of DACT2 was significantly associated with tumor stage and metastasis (P < 0.01, P < 0.05). DACT2 suppressed colony formation, cell migration and invasion in esophageal cancer cells, and it also suppressed esophageal cancer cell xenograft growth. DACT2 inhibited Wnt signaling in human esophageal cancer cells. In conclusion, DACT2 is frequently methylated in human esophageal cancer and its expression is regulated by promoter region methylation. DACT2 suppresses esophageal cancer growth by inhibiting Wnt signaling. PMID:26919254

1H-NMR based metabonomic profiling of human esophageal cancer tissue

Background The biomarker identification of human esophageal cancer is critical for its early diagnosis and therapeutic approaches that will significantly improve patient survival. Specially, those that involves in progression of disease would be helpful to mechanism research. Methods In the present study, we investigated the distinguishing metabolites in human esophageal cancer tissues (n = 89) and normal esophageal mucosae (n = 26) using a 1H nuclear magnetic resonance (1H-NMR) based assay, which is a highly sensitive and non-destructive method for biomarker identification in biological systems. Principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and orthogonal partial least-squares-discriminant anlaysis (OPLS-DA) were applied to analyse 1H-NMR profiling data to identify potential biomarkers. Results The constructed OPLS-DA model achieved an excellent separation of the esophageal cancer tissues and normal mucosae. Excellent separation was obtained between the different stages of esophageal cancer tissues (stage II = 28; stage III = 45 and stage IV = 16) and normal mucosae. A total of 45 metabolites were identified, and 12 of them were closely correlated with the stage of esophageal cancer. The downregulation of glucose, AMP and NAD, upregulation of formate indicated the large energy requirement due to accelerated cell proliferation in esophageal cancer. The increases in acetate, short-chain fatty acid and GABA in esophageal cancer tissue revealed the activation of fatty acids metabolism, which could satisfy the need for cellular membrane formation. Other modified metabolites were involved in choline metabolic pathway, including creatinine, creatine, DMG, DMA and TMA. These 12 metabolites, which are involved in energy, fatty acids and choline metabolism, may be associated with the progression of human esophageal cancer. Conclusion Our findings firstly identify the distinguishing metabolites in different

The aim of this study was to describe the prevalence of esophageal atresia/stenosis and small intestinal atresia/stenosis in Nagano, Japan, together with associated anomalies, prenatal diagnosis and survival. A population-based cohort study of the prevalence of esophageal atresia/stenosis and small intestinal atresia/stenosis was conducted in Nagano in January 1993-December 2011. The Mann-Whitney test, χ(2) test and Kruskal-Wallis test were used to compare variables. P < 0.05 was considered statistically significant. In total, 74 cases of esophageal atresia/stenosis and 87 cases of small intestinal atresia/stenosis (31 duodenal, 56 jejuno-ileal) were identified. Prevalences were 1.97 for esophageal atresia/stenosis and 2.23 for small intestinal atresia/stenosis (0.83 for duodenal atresia/stenosis and 1.49 for jejuno-ileal atresia/stenosis) per 10,000 births, respectively. The prevalence of esophageal atresia/stenosis increased significantly from 1993-2001 to 2002-2011 (relative risk [RR], 1.6), as did the prevalences of duodenal atresia/stenosis (RR, 2.2) and jejuno-ileal atresia/stenosis (RR, 3.1). Chromosomal anomalies, particularly trisomy 21, were seen significantly more often in association with duodenal atresia/stenosis (55%) than with esophageal atresia/stenosis (28%, P < 0.01) or jejuno-ileal atresia/stenosis (2%, P < 0.01). The proportion of patients associated with prenatally diagnosed chromosomal anomaly was higher compared to postnatal diagnosis (P < 0.01) in the esophageal atresia/stenosis group. The prevalence of esophageal and small intestinal atresia/stenosis increased significantly from 1993-2001 to 2002-2011. Prenatally diagnosed esophageal atresia/stenosis is associated with multiple anomalies, particularly chromosomal anomalies, compared to other small intestine atresia/stenosis. © 2014 Japan Pediatric Society.

Histologic definition of gastro-esophageal reflux disease.

PubMed

Chandrasoma, Parakrama T

2013-07-01

To review recent data supporting the development of new histology-based definitions of gastro-esophageal reflux disease (GERD). Three precisely definable columnar epithelial types--cardiac, oxyntocardiac and intestinal--may be interposed between esophageal squamous epithelium and gastric oxyntic (acid secreting) mucosa. This enables definition of a new histologic concept: the squamo-oxyntic gap. The squamo-oxyntic gap is zero or very small in autopsies performed on patients without evidence of GERD. The gap progressively increases in length with the severity of GERD, indicating that the squamo-oxyntic gap is a marker for chronic GERD. The distal part of the gap lines gastric-type rugal folds and, therefore, is distal to the present endoscopic definition of the gastro-esophageal junction. I contend that this distal gap segment (which has esophageal submucosal glands) is actually the dilated distal esophagus; this is the pathologic correlate of destruction of the abdominal segment of the lower esophageal sphincter. The dilated distal esophagus is mistaken for 'gastric cardia' by present endoscopic definitions. I believe that these data support the adoption of novel histologic definitions of GERD as follows: the presence of any squamo-oxyntic gap defines GERD; the length of the gap is a measure of severity of chronic GERD; and the presence of intestinal metaplasia in the gap defines Barrett esophagus and cancer risk.

Multidisciplinary approach for patients with esophageal cancer

Patients with esophageal cancer have a poor prognosis because they often have no symptoms until their disease is advanced. There are no screening recommendations for patients unless they have Barrett’s esophagitis or a significant family history of this disease. Often, esophageal cancer is not diagnosed until patients present with dysphagia, odynophagia, anemia or weight loss. When symptoms occur, the stage is often stage III or greater. Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection. The treatment of patients who have locally advanced esophageal cancer is more complex and controversial. Despite multiple trials, treatment recommendations are still unclear due to conflicting data. Sadly, much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically. Additionally, studies have been underpowered or stopped early due to poor accrual. In the United States, concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient. Patients who have metastatic disease are treated palliatively. The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer, and to review the literature which guides our treatment recommendations.

A 53-year-old male developed cervical esophageal stenosis after esophageal bypass surgery using a right colon conduit. The esophageal bypass surgery was performed to treat multiple esophageal strictures resulting from corrosive ingestion three years prior to presentation. Although the patient underwent several endoscopic stricture dilatations after surgery, he continued to suffer from recurrent esophageal stenosis. We planned cervical patch esophagoplasty with a pedicled skin flap of sternocleidomastoid (SCM) muscle. Postoperative recovery was successful, and the patient could eat a solid meal without difficulty and has been well for 18 mo. SCM flap esophagoplasty is an easier and safer method of managing complicated and recurrent cervical esophageal strictures than other operations.

A 69-year-old man was admitted to the emergency department 3 hours after ingestion of a bleaching agent containing hypochlorous acid and sodium hydroxide in a suicide attempt. Enhanced chest computed tomography scans taken on admission indicated an edematous esophagus and air bubbles in the mediastinum. He underwent endotracheal intubation and mechanical ventilation until day 9 because of laryngeal edema. On day 10, his endoscopy indicated diffuse reddish mucosal hyperemia, erosions, and lacerated mucosal lesions in the esophagus that were indicative of grade 2b corrosive esophagitis. Treatment with a proton pump inhibitor was initiated, with which the condition of the esophagus improved, and on day 44, a slight stricture of the upper part of the esophagus was observed. He was discharged on day 64 without any complaints. The ingestion of sodium hypochlorite induces corrosive esophagitis and acute phase of gastritis. Ingestion of any corrosive agent is known as a risk factor for esophagus cancer in the long-term. In such cases with esophageal stricture, esophagectomy is recommended for preventing esophagus cancer. Considering the age of the patient, however, he did not undergo esophagectomy.

AIM: To assess the outcome of different treatments in patients admitted for esophageal achalasia in the United States. METHODS: This is a retrospective analysis using the Nationwide Inpatient Sample over an 8-year period (2003-2010). Patients admitted with a primary diagnosis of achalasia were divided into 3 groups based on their treatment: (1) Group 1: patients who underwent Heller myotomy during their hospital stay; (2) Group 2: patients who underwent esophagectomy; and (3) Group 3: patients not undergoing surgical treatment. Primary outcome was in-hospital mortality. Secondary outcomes included length of stay (LOS), discharge destination and total hospital charges. RESULTS: Among 27141 patients admitted with achalasia, nearly half (48.5%) underwent Heller myotomy, 2.5% underwent esophagectomy and 49.0% had endoscopic or other treatment. Patients in group 1 were younger, healthier, and had the lowest mortality when compared with the other two groups. Group 2 had the highest LOS and hospital charges among all groups. Group 3 had the highest mortality (1.2%, P < 0.001) and the lowest home discharge rate (78.8%) when compared to the other groups. The most frequently performed procedures among group 3 were esophageal dilatation (25.9%) and injection (13.3%). Among patients who died in this group the most common associated morbidities included acute respiratory failure, sepsis and aspiration pneumonia. CONCLUSION: Surgery for achalasia carries exceedingly low mortality in the modern era; however, in complicated patients, even less invasive treatments are burdened by significant mortality and morbidity.

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.

Motility abnormalities in esophageal body in GERD: are they truly related to reflux?

Esophageal motility abnormalities have been observed in patients with gastroesophageal reflux disease. The aim of the present study was to determine if esophageal motor disorders in patients with a positive response to the omeprazole test are related to the existence of reflux or they are concomitant findings. A 24-hour pH monitoring and a stationary manometry were performed on 128 patients: 49 of them had normal manometry, 31 hypotensive lower esophageal sphincter, 29 motor disorder in esophageal body, and 19 hypotensive lower esophageal sphincter and motor disorder in esophageal body. We found an association between the presence of abnormal reflux and motor disorder in esophageal body (chi test; P < 0.05). However, ineffective esophageal motility was the disorder most strongly related to reflux, whereas the hypercontractile disorders were not clearly attributed to it. Esophageal manometric abnormalities should be considered cautiously before considering a motor disorder as a consequence of abnormal reflux.

Impact of Weight Loss Surgery on Esophageal Physiology

PubMed Central

Naik, Rishi D.; Choksi, Yash A.

2015-01-01

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.

A case of esophageal stricture after iodine 131 ablation.

2012-01-01

To report the first case of esophageal stricture as a complication of radioiodine (¹³¹I) ablation therapy. We review the medical and surgical history of this patient and discuss various potential causes of the esophageal stricture. A 79-year-old woman presented with increasing dysphagia and weight loss of about 4.5 kg after recent ¹³¹I therapy for thyroid cancer remnant ablation. Her pertinent history included gastroesophageal reflux disease, an anterior midcervical esophageal web, and a distal esophageal stricture. She also had a history of radiation therapy to her chest for breast cancer about 28 years previously. On the day of ¹³¹I therapy, the 5.5-GBq ¹³¹I capsule lodged accidentally in her midcervical area for approximately 2.5 hours. The resulting radiation dose to the proximal esophagus was estimated to be 7.86 Gy from gamma radiation and possibly as high as several thousand grays from beta radiation. During this time, the esophagus had possible direct exposure to the sodium phosphate dibasic that was used as filler in the sodium iodide capsule. Because of the worsening dysphagia, an esophagogastroduodenoscopy was performed 4 weeks after the ¹³¹I therapy, which showed a new proximal esophageal stricture. We believe that the additional localized radiation and sodium phosphate exposure from the lodging of the ¹³¹I capsule may have contributed to the development of a proximal esophageal stricture. To our knowledge, such an occurrence has not previously been described in the medical literature. For prevention of such an occurrence, we recommend a careful swallowing evaluation of patients with any history of esophageal radiation exposure, dysphagia, or esophageal strictures before administration of ¹³¹I in capsule form. Alternative methods of ¹³¹I delivery, if available, should be considered.

The esophagus consists of two different parts. In humans, the cervical esophagus is composed of striated muscles and the thoracic esophagus is composed of phasic smooth muscles. The striated muscle esophagus is innervated by the lower motor neurons and peristalsis in this segment is due to sequential activation of the motor neurons in the nucleus ambiguus. Both primary and secondary peristaltic contractions are centrally mediated. The smooth muscle of esophagus is phasic in nature and is innervated by intramural inhibitory (nitric oxide releasing) and excitatory (acetylcholine releasing) neurons that receive inputs from separate sets of preganglionic neurons located in the dorsal motor nucleus of vagus. The primary peristalsis in this segment involves both central and peripheral mechanisms. The primary peristalsis consist of inhibition (called deglutitive inhibition) followed by excitation. The secondary peristalsis is entirely due to peripheral mechanisms and also involves inhibition followed by excitation. The lower esophageal sphincter (LES) is characterized by tonic muscle that is different from the muscle of the esophageal body. The LES, like the esophageal body smooth muscle, is also innervated by the inhibitory and excitatory neurons. The LES maintains tonic closure due to its myogenic property. The LES tone is modulated by the inhibitory and the excitatory nerves. Inhibitory nerves mediate LES relaxation and the excitatory nerves mediate reflex contraction or rebound contraction of the LES. Clinical disorders of esophageal motility can be classified on the basis of disorders of the inhibitory and excitatory innervations and the smooth muscles. PMID:18364578

Esophageal food impaction (EFI) is a gastrointestinal emergency requiring immediate evaluation in the emergency room (ER) and an esophagogastroduodenoscopy (EGD) for disimpaction. EFI is also a distinct presenting feature of eosinophilic esophagitis (EoE). This study aimed at understanding the management of EFI among gastroenterologists (GIs) and estimated its impact on identification of EoE in USA. GIs associated with three major gastroenterology societies based in USA were invited to participate in a web-based survey. Information on the resources available and utilized, and the clinical decision-making process related to management of EFI cases was collected and analyzed. Of 428 responses, 49% were from pediatric GIs, 86% practiced in the USA, and 78% practiced in an academic setting. Compared to the pediatric GIs, adult GIs were more likely to perform EGD in the emergency room [OR 87.96 (25.43-304.16)] and advance the food bolus into stomach [5.58 (3.08-10.12)]. Only 34% of respondents obtained esophageal biopsies during EGD, and pediatric GIs were more likely to obtain esophageal biopsies [3.49 (1.12-10.84)] compared to adult GIs. In USA, by our conservative estimates, 10,494 patients presenting to ER with EFI and at risk of EoE are likely being missed each year. EFI management varies substantially among GIs associated with three major gastroenterology societies in USA. Based on their practice patterns, the GIs in USA are likely to miss numerous EoE patients presenting to ER with EFI. Our findings highlight the need for developing and disseminating evidence-based EFI management practice guidelines.

Compared to conventional fractionated-dose radiotherapy, high hypofractionated-dose radiotherapy could yield tumoricidal effects. However, few clinical trials of hypofractionated radiotherapy in loco-regionally advanced incurable esophageal cancer at present have yet been performed. The purpose of the current study was to evaluate the efficacy and toxicity of hypofractioned radiation with three-dimensional conformal radiotherapy for clinical T3-4N0-1M0 stage esophageal carcinoma. From September 2003 to December 2005, 45 patients with locally advanced esophageal carcinoma were grouped and received three-dimensional conformal hypofractioned radiotherapy (3D-CRT) whose fractionated dose was gradually increase per group. Radiotherapy was administered to a total dose of from 50 to 54 Gy (fractionated dose of from 3.0 to 6.0 Gy, 3 times weekly), over a 3-4 week period. And patients received 4 cycles chemotherapy. The median follow-up period for survivors was 38 months. Treatment tolerance rate was 78.8% with daily dose of from 3 to 5 Gy. There are 21.2% patients occurring Grade ≥ 3 acute toxicities. But patients couldn't tolerate daily dose of 6 Gy (55.6%). The 1-year, 2-year and 3-year local control rates were 62%, 49% and 39% respectively. And the 1-year, 2-year and 3-year overall survival rates were 34%, 21% and 9% respectively. The median overall survival time was 17 months. At the time of following up, 13 patients (31.0%) had occurred esophageal late complications, with mainly esophageal perforation, hemorrhage or stenosis, including initial stenosis aggravation. Therefore hypofractionated irradiation was thought to be feasible for clinical T3-4N0-1M0 stage esophageal carcinoma. And daily dose of ≤5 Gy was comparatively suitable in hypofractionated irradiation for esophageal carcinoma, and the patients tolerated well. But further research was in need also.

Systemic sclerosis (SSc) is a multisystemic autoimmune connective tissue disorder; in the gastrointestinal tract, the esophagus is the most commonly affected organ. Symptoms of esophageal disease are due to gastroesophageal reflux disease (GERD) and esophageal motor dysfunction. Since the development of high-resolution manometry (HRM), this method has been preferred for the study of SSc patients with esophageal involvement. Using HRM, classic scleroderma esophagus, defined as absent or ineffective peristalsis of the distal esophagus in combination with a hypotensive lower esophageal sphincter, was found in as many as 55% of SSc patients. Endoscopy is the appropriate test for evaluating dysphagia and identifying evidence and possible complications of GERD. In the therapeutic area, treatment ranges from general supportive measures to the administration of drugs such as proton pump inhibitors and/or prokinetics. However, as many SSc patients do not respond to existing therapies, there is an urgent need for new therapeutic modalities. Buspirone, a 5-hydroxytryptamine 1A receptor agonist, could be a putative therapeutic option, as it was found to exert a significant beneficial effect in SSc patients with esophageal involvement. This review summarizes our knowledge concerning the evaluation and management of esophageal manifestations in SSc patients, including emerging therapeutic modalities.

This study was designed to determine the protective effect of Rumex Aquaticus Herba extracts containing quercetin-3-β-D-glucuronopyranoside (ECQ) on experimental reflux esophagitis. Reflux esophagitis was induced by surgical procedure. The rats were divided into seven groups, namely normal group, control group, ECQ (1, 3, 10, 30 mg/kg) group and omeprazole (30 mg/kg) group. ECQ and omeprazole groups received intraduodenal administration. The Rats were starved for 24 hours before the experiments, but were freely allowed to drink water. ECQ group attenuated the gross esophagitis significantly compared to that treated with omeprazole in a dose-dependent manner. ECQ decreased the volume of gastric juice and increased the gastric pH, which are similar to those of omeprazole group. In addition, ECQ inhibited the acid output effectively in reflux esophagitis. Significantly increased amounts of malondialdehyde (MDA), myeloperoxidase (MPO) activity and the mucosal depletion of reduced glutathione (GSH) were observed in the reflux esophagitis. ECQ administration attenuated the decrement of the GSH levels and affected the MDA levels and MPO activity. These results suggest that the ECQ has a protective effect which may be attributed to its multiple effects including anti-secretory, anti-oxidative and anti-inflammatory actions on reflux esophagitis in rats.

Endoscopic submucosal dissection (ESD) is a more difficult technique for esophageal cancer than for gastric cancer because the working space for esophageal ESD is small. Further, the difficulty level gradually increases depending on the size of the carcinoma. To overcome these difficulties, double endoscopic intraluminal operation (DEILO), which enables the resection of mucosal lesions using two fine endoscopes and monopolar shears, was reported previously. Here, we report the utility of DEILO for esophageal cancer. A total of 26 esophageal cancer patients (19 men and seven women) with 26 lesions treated using DEILO between 2011 and 2014 at Gunma University Hospital were included. We evaluated the utility and safety of DEILO for early esophageal cancer. For all patients (100%), the DEILO procedure was performed successfully, and en bloc resection was achieved. The median operation time, postoperative hospital stay, and the longitudinal dimension of resected specimens were 123 min (range 45-236 min), 5 days, and 32 mm, respectively. Perioperative perforation, pneumothorax, and mediastinal emphysema were not recognized. Only one patient was diagnosed with a postoperative hemorrhage, but the bleeding was successfully treated by bleeding vessel coagulation. DEILO has good utility as a technique of ESD for early esophageal cancers. Additional improvement and advancement of the procedure will increase the indication of DEILO.
