While numerous surveys of pattern of practices of palliative radiotherapy (RT) in advanced esophageal cancers have been published in developed countries, there is no such survey in African countries. During and after a regional training course by the International Atomic Energy Agency (IAEA) in palliative cancer care, a questionnaire was distributed to African RT centers to gather information about infrastructure and human resources available, and the pattern of practice of palliative RT for esophageal cancers. Twenty-four of the 35 centers (60%) completed the questionnaire. Twenty out of 23 (87%) centers treat patients with esophageal cancer presenting with dysphagia using external beam RT (16 centers external beam RT alone and 4 centers also use brachytherapy as a boost). Twelve (60%) centers prescribe RT doses of 30 Gy in 10 fractions and 2 centers 20 Gy in 5 fractions. Eighteen centers (78%) have low dose rate (LDR) brachytherapy, and 9 (39%) centers have high dose rate (HDR) brachytherapy. One center only used HDR brachytherapy alone to a dose of 16 Gy in 2 fractions over 8 days. RT remains a major component of treatment of patients with esophageal cancers in African countries. Still, there is a great variety among centers in both indications for RT and its characteristics for a treatment indication.

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% confidence interval (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. (author)

Endoscopic placement of fully covered self-expanding metal stents (FCSEMS) to treat malignant dysphagia in patients with esophageal cancer significantly improves dysphagia; however, these stents have a high migration rate. To determine whether FCSEMS fixation using an endoscopic suturing device treated malignant dysphagia and prevented stent migration in patients with locally advanced esophageal cancer receiving neoadjuvant therapy when compared to patients with FCSEMS placement alone. A review of patients with locally advanced esophageal cancer who underwent FCSEMS placement at 3 centers was performed. Patients were divided into two groups: Group A (n = 26) was composed of patients who underwent FCSEMS placement with suture placement, and Group B (n = 67) was composed of patients with FCSEMS placement alone. There were no significant differences between Groups A and B in demographics, and tumor characteristics. The technical success rate for stent placement was 100 %. There was no difference between Groups A and B in the median stent diameter and stent lengths. Mean dysphagia score obtained at 1 week after stent placement had improved significantly from baseline (2.4 and 1, respectively, p esophageal FCSEMSs by using an endoscopic suturing device in patients receiving neoadjuvant therapy was shown to be feasible, safe, and relatively effective at preventing stent migration compared to those who had stent placed alone.

Advanced esophageal cancer (AEC) is diagnosed during those stages in which surgery is possible, it is palliative for disphagia, with high morbimortality.In inoperable or irresectable cases, resorting to alternative treatment such as radiotherapy or endoscopy may palliate dsphagia.Endoscopically it is possible to place a transtumoral nasogastric catheter (NGC) for preoperative nutrition or branchial therapy (intratumoral iridium).It is possible to dilate the tumor and place and indwelling plastic or auto expandable prosthesis or to inject absolute intratumoral alcohol.There is and evaluation of results and morbimortality of personal case material through the retrospective study of 54 patients in whom 120 procedures such as those referred to above were carried out.The series includes 41 men and 13 women (3-1), 79.5% of which were of ages between 61 and 90.Optic fiber endoscopes or video endoscopes, coaxial dilators, hydro-pneumatic balloons, metallic guides and non industrial and autoexpandable plastic prosthesis were used; 34.1% of procedures were performed under used; 34.1% of procedures were performed under radioscopy.Eleven patient (8 for nutritional purposes and 3 for brachiotherapy)form part of Groups 1 and 2 of NGC.Group 3 consist of:dilations of radicular stenosis with or without neopasic recurrence, or neoplasic infiltration of esophagus, 6 patient; Group 4: 14 patients for the purpose of dilation of esophageal neoplasm; Group 5:prosthesis, 12 patients; Group 6: 11 patients with anastomotic stenosis.In patients in Group 1-2-3 solution was achieved.In Group 3 there was 1 perforation.In Group 4, out of 14 patient 13 were dilated.In Group 5 it proved impossible to place prosthesis in 2 patient, (3.7%).The conclusion arrived at is that various endoscopic techniques may palliate disphagia in patient with AEC, collaborate with preoperative nutrition through enteral path, with brachioterapy or by treating post surgical stenosis, with low mortality

1998-01-01

Full Text Available Endoscopic treatment has generally been accepted in the management of bleeding esophageal varices. Both the control of acute variceal bleeding and elective variceal eradication to prevent recurrent bleeding can be achieved via endoscopic methods. In contrast to acute and elective treatment, the role of endoscopic therapy in asymptomatic patients who have never had variceal bleeding remains controversial because of the rather disappointing results obtained from prophylactic sclerotherapy. Most published randomized controlled trials showed that prophylactic sclerotherapy had no effect on survival. In some studies, neither survival rate nor bleeding risk was improved. In this article, the author champions the view that asymptomatic esophageal varices should be endoscopically treated.

The purpose of this study was to evaluate the prognostic impact of endoscopic traversability in patients with locally advanced esophageal squamous cell carcinoma.This retrospective study was based on medical records from a single tertiary medical center. The records of 317 patients with esophageal squamous cell carcinoma treated with surgery or definitive chemoradiotherapy (CRT) between January 2009 and March 2016 were reviewed. Finally, we retrieved the data on 168 consecutive patients. These 168 patients were divided into 2 groups based on their endoscopic traversability findings: Group A (the endoscope traversable group), and Group B (the endoscope non-traversable group). We then retrospectively compared the clinical characteristics of these 2 groups.The endoscope non-traversable group (Group B) revealed an advanced clinical stage, a poor Eastern Cooperative Oncology Group (ECOG) score, a lower serum albumin level, a higher rate of requirement for esophageal stent insertion and definitive CRT as initial treatment than the endoscope traversable group (Group A). Patients with endoscope traversable cancer showed a significantly higher 3-year overall survival and 3-year relapse-free survival than patients who were endoscope non-traversable (53.8% vs 17.3%, P squamous cell carcinoma treated with definitive CRT, the serum albumin level squamous cell carcinoma treated with definitive CRT is a significant prognostic factor.

Esophageal cancer patients are often associated with multiple primary cancers (MPC). The aim of this study is to evaluate the effect of MPC on prognosis in esophageal cancer patients treated by radiotherapy. Between 2001 and 2008, esophageal cancer patients treated by definitive radiotherapy at Gunma Cancer Center were retrospectively reviewed. Exclusion criteria were preoperative or postoperative radiotherapy, palliative radiotherapy, follow-up of <6 months, radiation dose of <50 Gy and no information on MPC. We analyzed 167 esophageal cancer patients and 56 (33.5%) were associated with MPC. Gastric cancer was the most frequent tumor (38.2%), followed by head and neck cancer (26.5%). Median follow-up time was 31.5 months (range 6.1-87.3 months). Patients with MPC included more stage I/II esophageal cancer than those without MPC (66.1% vs. 36.9%, P<0.01). The 5-year overall survival rate for esophageal cancer with MPC was relatively better than those without MPC (46.1% vs. 26.7%), although the difference did not reach statistical significance in univariate analysis (P=0.09). Stage I/II esophageal cancer patients had a significantly better overall survival than stage III/IV patients (P<0.01). Among esophageal cancer patients with MPC, there was no difference in overall survival between antecedent and synchronous cancer (P=0.59). Our study indicated that the prognosis of esophageal cancer patients treated by radiotherapy was primarily determined by the clinical stage itself, but not the presence of MPC. (author)

Advances in esophageal motor disorders.

2008-07-01

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.

We treated 20 cases of squamous cell carcinoma of the esophagus, combining radiation, chemotherapy and hyperthermia. Hyperthermia combining chemotherapy consisting of cis-dichlorodiamine platinum (25∼75 mg/body, every week) in the form continuous intravenous infusion was given. The hyperthermochemotherapy only had limited effectiveness but good response was noted for post-operative and post-irradiative adjuvant hyperthermochemotherapy. Heating could alleviate some chemotherapeutic side effects, especially renal damage or audiometric disturbance. Furthermore, hyperthermia relieved some radiation side effects, such as radiation-induced scleroderma probably due to hypercirculation. We believe that combining hyperthermochemotherapy with radiation is promising for advanced, recurrent esophageal cancer. (author)

Objective: To explore radiation-induced esophagitis and its related factors in the patients with local advanced non-small cell lung cancer (NSCLC) which were treated with three-dimensional conformal radiation therapy (3D-CRT). Methods: From January 2001 to December 2008, 203 patients who suffered from stage Ⅲ NSCLC were achieved, including 163 males and 40 females, with a median age of 63 years old, while 79 cases were in stage Ⅲ_a and 124 in stage Ⅲ_b. The equivalent median dose of tumor was 62 Gy(range of 50-78 Gy). Among them, 74 cases were administered with radiotherapy alone, 45 with sequential radiotherapy and chemotherapy, 87 cases with concurrent radiochemotherapy. Radiation esophagitis was evaluated with RTOG standard. The dosimetric parameters was estimated from dose volume histogrma (DVH). The clinical and dosimetric parameters of radiation esophagitis were evaluated by spearman correlatived univariate and Logistic multivariable analysis.Results After radiotherapy, out of 203 patients, 87 had acute radiation esophagitis(RE), 47 in grade 1, 37 in grade 2, and 3 in grade 3 RE. According to spearman correlatived analysis, the correlatived factors included ages, chemotherapy, GTV, PTV, the mean doses of PTV and lung, the max and mean dose of esophagus, V_4_0, V_4_5, V_5_0, V_5_5, V_6_0, length of esophagus (total circumference) treated with 45 Gy (LETT_4_5), and LETT_5_0 (r = -0.162-0.235, P 0.05). There were 21 factors, such as gender, age, smoking, clinical stage, site of tumor, chemotherapy, GTV, PTV, mean dose of PTV and lung, max and mean dose of esophagus, V_4_0-V_6_0 of esophagus, LETT_4_5_-_6_0, incorporated into multivariable analysis, only chemotherapy and V_4_5 of esophagus were independent predicted factors(Wald = 4.626, 9.882, P < 0.05). Conclusions: In local advanced NSCLC after 3D-CRT, chemotherapy(especially concurrent radiochemotherapy) could increase radiation-induced esophagitis. The parameter of DVH could also be used to predict

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.

Objective: To compare the occurrence of complications between conventional self-expandable metal stent and internal irradiation stent insertion in treating patients with advanced esophageal carcinomas. Methods: A total of 32 patients with advanced esophageal carcinoma were randomly divided into irradiation stent group (n=15) and conventional stent group (n=17). Internal irradiation stent loaded with 125 I seeds was employed in patients of irradiation stent group, while conventional self-expandable metal stent was used in patients of conventional stent group. After the treatment, clinical follow-up was regularly conducted. Postoperative complications such as fever, severe chest pain, cough, esophageal perforation, pneumonia, hemorrhage, stent migration and restenosis, etc. were observed. Results: No significant difference in the occurrence of fever, severe chest pain, esophageal perforation and hemorrhage existed between the two groups (P>0.05). The difference in the occurrence of long-term complications such as stent migration or restenosis between the two groups was out statistically significant (P>0.05). However, the restenosis in irradiation stent group occurred obviously much later than that in conventional stent group. Conclusion: For the treatment of advanced esophageal carcinomas, the insertion of internal irradiation esophageal stent is safe. It dose not increase the incidence of postoperative complications. Therefore, it is worth popularizing this technique in clinical practice. (authors)

Advanced pulmonary disorders are linked to esophageal hypomotility and reflux disease. However, characterization of esophageal function using high resolution manometry (HRM) and ambulatory pH monitoring, segregation by pulmonary pathology, and comparison to traditional reflux disease are all limited in the literature. Over a 4 year period, 73 patients (55.2 ± 1.3 years, 44F) were identified who underwent esophageal function testing as part of lung transplant evaluation for advanced pulmonary disease (interstitial lung disease, ILD = 47, obstructive lung disease, OLD = 24, other = 2). Proportions of patients with motor dysfunction (≥ 80% failed sequences = severe hypomotility) and/or abnormal reflux parameters (acid exposure time, AET ≥ 4%) were determined, and compared to a cohort of 1081 patients (48.4 ± 0.4 years, 613F) referred for esophageal function testing prior to antireflux surgery (ARS). The proportion of esophageal body hypomotility was significantly higher within advanced pulmonary disease categories (35.6%), particularly ILD (44.7%), compared to ARS patients (12.1%, P esophageal motor pattern or reflux evidence. Interstitial lung disease has a highly significant association with esophageal body hypomotility. Consequently, prevalence of abnormal esophageal acid exposure is high, but implications for post lung transplant chronic rejection remain unclear. © 2013 John Wiley & Sons Ltd.

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.

Five out 165 cases (3.0%) which were treated for non-small cell lung cancer with radiotherapy (98 cases were treated with chemoradiotherapy, and the other 67 case, radiotherapy alone) developed esophageal stricture. Their clinical courses, the relationship among radiation dosage, combination with chemotherapy, the length of the irradiated esophagus, and the occurrence of esophageal stricture were reviewed. One of the 5 cases was a case with lung cancer in Bloom's syndrome, which developed an esophageal stricture after receiving only 30.6 Gy (the TDF value was 46.2) to the esophagus. This case suggests the possibility that a patient with Bloom's syndrome is more radiosensitive than normal controls. The other 4 cases were treated with combined chemoradiotherapy. One of the 4 cases was treated with concomitant use of bleomycin (BLM), while the TDF value was not more than 100 (75.4). The concomitant use of BLM was almost certainly the cause of the esophageal stricture. The other 3 cases were treated with chemoradiotherapy, the TDF values of which were more than 100 (108.7, 112.5, and 129.3). The chemotherapy combined with radiotherapy and the overdosage were considered to be the cause of the esophageal stricture in these 3 cases. These data suggest that in Bloom's syndrome, radiotherapy should be performed carefully and that BLM should not be used simultaneously with irradiation to the esophagus. It is also believed that a radiation dose over 100 in TDF value to the esophagus should be discouraged when chemotherapy is codmbined. (author)

Percutaneous endoscopic gastrostomy for nutritional palliation of upper esophageal cancer unsuitable for esophageal stenting

Ana Grilo

2012-09-01

Full Text Available CONTEXT: Esophageal cancer is often diagnosed at an advanced stage and has a poor prognosis. Most patients with advanced esophageal cancer have significant dysphagia that contributes to weight loss and malnutrition. Esophageal stenting is a widespread palliation approach, but unsuitable for cancers near the upper esophageal sphincter, were stents are poorly tolerated. Generally, guidelines do not support endoscopic gastrostomy in this clinical setting, but it may be the best option for nutritional support. OBJECTIVE: Retrospective evaluation of patients with dysphagia caused advanced esophageal cancer, no expectation of resuming oral intake and with percutaneous endoscopic gastrostomy for comfort palliative nutrition. METHOD: We selected adult patients with unresecable esophageal cancer histological confirmed, in whom stenting was impossible due to proximal location, and chemotherapy or radiotherapy were palliative, using gastrostomy for enteral nutrition. Clinical and nutritional data were evaluated, including success of gastrostomy, procedure complications and survival after percutaneous endoscopic gastrostomy, and evolution of body mass index, albumin, transferrin and cholesterol. RESULTS: Seventeen males with stage III or IV squamous cell carcinoma fulfilled the inclusion criteria. Mean age was 60.9 years. Most of the patients had toxic habits. All underwent palliative chemotherapy or radiotherapy. Gastrostomy was successfully performed in all, but nine required prior dilatation. Most had the gastrostomy within 2 months after diagnosis. There was a buried bumper syndrome treated with tube replacement and four minor complications. There were no cases of implantation metastases or procedure related mortality. Two patients were lost and 12 died. Mean survival of deceased patients was 5.9 months. Three patients are alive 6, 14 and 17 months after the gastrostomy procedure, still increasing the mean survival. Mean body mass index and laboratory

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.

We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0. A complete response appeared in 12 patients, whereas a partial response appeared in 1 patient. The mean survival time of the

Full Text Available Abstract Background Complete remission from advanced-stage synchronous double primary (SDP esophageal and gastric adenocarcinoma by chemotherapy alone is rare. We report a case of advanced-stage SDP esophageal and gastric adenocarcinoma in which a complete response to treatment was obtained with S-1 and cis-diamminedichloroplatinum (CDDP. Case presentation The patient was a 74-year-old man referred to our hospital complaining of dysphagia. Gastrointestinal endoscopy was performed and advanced-stage SDP esophageal and gastric adenocarcinoma diagnosed. Computed tomography revealed multiple regional lymph node metastases in the mediastinum. Neoadjuvant chemotherapy with S-1 and CDDP for advanced esophageal and gastric cancer was planned. An endoscopy following two courses of chemotherapy revealed that the esophageal cancer had been replaced with a normal mucosal lesion and the gastric tumor with a scar lesion; the results of biopsies of both were negative for cancer. Computed tomography revealed that the multiple lymph node metastases had disappeared. We diagnosed a complete response to S-1 and CDDP in advanced-stage SDP esophageal and gastric cancer. The patient is still alive with no signs of recurrence 22 months after the disappearance of the original tumor and metastatic lesions without surgical treatment. Conclusion These results suggest that complete remission from advanced-stage esophageal and gastric cancer can be obtained with chemotherapy with S-1 plus CDDP.

We performed the retrospective analysis to find the outcome of external beam radiotherapy alone in advanced esophageal cancer patients. One hundred and six patients treated with external beam radiotherapy alone between July 1990 and December 1996 were analyzed retrospectively. We limited the site of the lesions to the thoracic esophagus and cell type to the squamous cell carcinoma. Follow-up was completed in 100 patients (94%) and ranged from 1 month to 92 months (median; 6 months). The median age was 62 years old and male to female ratio was 104:2. Fifty-three percent was the middle thorax lesion and curative radiotherapy was performed in 83%. Mean tumor dose delivered with curative aim was 58.6 Gy (55-70.8 Gy) and median duration of the radiation therapy was days. The median survival of all patients was 6 months and 1-year and 2-year overall survival rate was 27% and 12%, respectively. Improvement of dysphagia was obtained in most patients except for 7 patients who underwent feeding gastrostomy. The complete response rate immediately after radiation therapy was 32% (34/106). The median survival and 2-year survival rate of the complete responder was 14 months and 30% respectively, while those of the nonresponder was 4 months and 0% respectively (p=0.000). The median survival and 2-year survival rate of the patients who could tolerate regular diet was 9 months and 16% while those of the patients who could not tolerate regular diet was 3 months and 0%, respectively (p=0.004). The survival difference between the patients with 5 cm or less tumor length and those with more than 5 cm tumor length was marginally statistically significant (p=0.06). However, the survival difference according to the periesophageal invasion or mediastinal lymphadenopathy in the chest CT imaging study was not statistically significant in this study. In a multivariate analysis, the statistically significant covariates to the survival were complete response to radiotherapy, tumor, length, and

Wistar rats were divided into seven groups: the normal group, the irradiated group, the preventive group treated with the normal dose of compound white peony root oral liquids (cWPROL) (immediately administered on the day after rats were irradiated), the preventive group treated with the high dose of cWPROL (immediately administered on the day after rats were irradiated), the group treated with normal dose of cWPROL (administered on the 7th day after rats were irradiated), the group treated with high dose of cWPROL (administered on the 7th day after rats were irradiated), the group treated with Western medicine administered from the seventh day after irradiation. The radiation esophagitis of rats was induced by single irradiation of 43 Gy gamma ray locally. Then the rats with radiation esophagitis were treated in different ways. The food weight, water volume intaked by the rats and its body weight change were observed; The rats were killed on the 14th day after irradiation and the leucocyte count and DIFF were analyzed and the esophageal pathological sections were made. The pathological change of rats' esophageal mucosa and ultrastructure change of cells were observed for different groups. The results showed all the cWPROL and Western medicine have therapeutic function of treating radiation-induced esophagitis of rats. The ultrastructure of cells of rats in the group treated with normal dose of cWPROL recovered. The food weight and water volume intaked by the rats had increased in the group infused with cWPROL compared with purely irradiated groups, especially in the preventive group treated with high dose of cWPROL. The weight of food, the WBC count, the lymphocyte differential count in the group which was treated with Western medicine decreased compared with the purely irradiated group. Lymphocyte differential count increased in the groups administered cWPROL compared with the purely irradiated group. The compound white peony root oral liquids serves the function

Full Text Available Objective: To investigate the effects of oxaliplatin, leucovorin and fluorouracil on serum tumor markers, VEGF, CRP and matrix metalloproteinases in patients with advanced esophageal cancer. Methods: From March 2012 to March 2017 a total of 248 patients with advanced esophageal cancer were selected as the study subjects. According to random data table, they were divided into control group (n=123 and observation group (n=125 according to random data table. The control group was treated with cisplatin combined with fluorouracil, leucovorin chemotherapy, and patients in the observation group received oxaliplatin, leucovorin and fluorouracil chemotherapy, all patients were treated for 2 cycles. The changes of serum tumor markers, VEGF, CRP and matrix metalloproteinase levels in the two groups before and after treatment was compared. Results: Before treatment, there was no significant difference of the levels of serum CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 between the control group and the observation group. Compared with the group before treatment, the levels of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the two groups were significantly lower. After treatment, the level of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the observation group was significantly lower than those of the control group. Conclusion: Oxaliplatin, leucovorin and fluorouracil chemotherapy can effectively reduce the levels of serum tumor markers, VEGF, CRP and matrix metalloproteinase in patients with advanced esophageal cancer, it has important clinical value.

To investigate factors influencing response and survival for patients with squamous cell cancer of the esophagus. Forty-nine patients with squamous cell cancer of the esophagus, classified by guidelines for the clinical and pathologic studies on carcinoma of the esophagus published by the Japanese Society for Esophageal Disease, were treated by concurrent chemoradiotherapy using chemotherapy consisting of cisplatin and 5-fluorouracil with definitive irradiation of 60 Gy concurrently. Endoscopic findings and biopsy were used for evaluating the response. Nurse charts recording patient's feeding status were adopted to estimate severity of dysphagia. Complete response (CR) rate was 69.4%, median survival time (MST) was 12.3 months, and median local failure-free survival time 7.3 months. Patients in early stage (= 32.4 months, 20.4 months, 20.4 months, 15.7 months, respectively). Patients in A3 stage were often suffered from severe dysphagia both before and after treatment (81.5%, 70.4%), respectively. Concurrent chemoradiotherapy was effective treatment for esophageal cancer. Degree of dysphagia was considered to be a good prognosticator of patients' survival. (author)

Introduction: Dysphagia is the main problem in patients with advanced nonresectable esophageal cancer. Palliation can be achieved by several treatment ways. We want to evaluate the efficacy of endoluminal brachytherapy (BT) for improvement of dysphagia, performance status, time of local tumor progress, and survival time. Methods: 6 patients with esophageal cancer stage IV received a palliative treatment with 192 Ir HDR BT. The dose per fraction was 5 Gy, calculated 1 cm from the surface of the applicator, the total dose was 20 Gy (four weekly applications). Symptoms, performance status and life quality score were investigated before each application and each 4 weeks after treatment. The results were compared with 10 historical patients who were treated by implantation of nitinol stents (Ultraflex, Boston Scient. Inc.). Results: The tumor stages in the BT-group were T4, T3, T2 three, two and one, and in the stent group three, two and five, respectively. Dysphagia improved in median from grade 1.7 to grade 0.5 (BT group) and from grade 2.6 to grade 1.8 (stent group). Karnowski status improved in the BT group from 70 % to 85 %, but did not change in the stent group (75%). A strong correlation between improvement of dysphagia and life quality score could be found especially in patients with initial high grade dysphagia. The only side effect of BT mostly after the 3 rd application was esophagitis grade 1 in 3 patients and grade 2 in 1 patient. Relief of the esophagitis after conservative therapy could be achieved within 1 week. In the BT group 3 patients were alive without local progress after 20, 13 and 2 weeks. The other 3 patients died from local progress (2 patients, after 20, 20 weeks) or from metastasis (1 patient, after 11 weeks). All patients in the stent group died from local progress. The median survival time is 17 ± 5.2 weeks in BT group vs. 8.8 ± 8.6 weeks in the stent group. Conclusion: Endoluminal brachytherapy seems to be an effective and well tolerable

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.

The objective of this study is to compare long-term outcomes between younger and older (70 y and above) esophageal cancer patients treated with curative intent. Overall survival (OS), disease-free survival (DFS), and locoregional recurrence-free interval were compared between older (70 y and above) and younger (below 70 y) esophageal cancer patients treated between 1998 and 2013. Treatment consisted of neoadjuvant chemoradiotherapy with surgery or definitive chemoradiotherapy: 36 to 50.4 Gy in 18 to 28 fractions combined with 5-fluorouracil/cisplatin or carboplatin/paclitaxel. The study comprised 253 patients, of whom 76 were 70 years and older. Median age was 64 years (range, 41 to 83). Most patients had stage II-IIIA disease (83%). Planned treatment was neoadjuvant chemoradiotherapy with surgery for 169 patients (41 patients aged 70 y and older) and definitive chemoradiotherapy for 84 patients (31 patients aged 70 y and older). The compliance to radiotherapy was 92%, with no difference between older and younger patients. In 33 patients (13 patients aged 70 y and older) planned surgery was not performed. Median follow-up was 4.9 years. Three-year OS was 42%. The multivariable analysis showed no statistical difference in OS or in DFS comparing older and younger patients: OS (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.61-1.28), DFS (HR, 0.87; 95% CI, 0.60-1.25). Elderly showed a longer locoregional recurrence-free interval; HR, 0.53 (95% CI, 0.30-0.92; P=0.02) and a higher pathologic complete response rate (50% vs. 25%; P=0.02). Long-term outcomes of older esophageal cancer patients (70 y and above) selected for treatment with neoadjuvant chemoradiotherapy followed by surgery or definitive chemoradiotherapy were comparable with the outcomes of their younger counterparts. Advanced age alone should not be a contraindication for potentially curative chemoradiotherapy-based treatment in esophageal cancer patients.

Prognosis of locally advanced esophageal cancer is poor. The greatest prognostic factor of locally advanced esophageal cancer is a local control. We experienced a case of T4 locally advanced thoracic esophageal cancer who was successfully resected without any combined resection after multimodality therapy. A male in 75-year-old. was diagnosed with type 3 locally advanced upper thoracic esophageal cancer whose metastatic right recurrent laryngeal lymph node invaded into the trachea. Definitive chemoradiation therapy(CRT)was performed, leading to a significant shrinkage of the main tumor, but T4 lesion remained. Next, adding DCF therapy(docetaxel, CDDP and 5-FU), a relief of T4 was finally obtained. Then, salvage surgery with subtotalesophagectomy and retrosternalesophagealreconstruction with gastric tube was performed, resulting in R0 resection without any combined resection. The postoperative course was uneventful, and the patient has been alive without recurrence for 1 year after surgery. In locally advanced cancer, focusing on T4 downstaging, it is significantly important in terms of safety, curativity and organ preservation to perform surgery after a sure sign of T4 relief by multimodality therapy.

Infants and children with esophageal atresia commonly present with swallowing dysfunction or dysphagia. Dysphagia can lead to a range of significant consequences such as aspiration pneumonia, malnutrition, dehydration, and food impaction. To improve oral intake, the clinical diagnosis of dysphagia in patients with esophageal atresia should focus on both the pharynx and the esophagus. To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagus, a detailed understanding of normal and abnormal deglutition is required through the use of adequate and objective assessment techniques. As clinical symptoms do not correlate well with conventional assessment methods of motor function such as radiology or manometry but do correlate with bolus flow, the current state-of-the-art diagnosis involves high-resolution manometry combined with impedance measurements to characterize the interplay between esophageal motor function and bolus clearance. Using a novel pressure flow analysis (PFA) method as an integrated analysis method of manometric and impedance measurements, differentiation of patients with impaired esophago-gastric junction relaxation from patients with bolus outflow disorders is clinically relevant. In this, pressure flow matrix categorizing the quantitative PFA measures may be used to make rational therapeutic decisions in patients with esophageal atresia. Through more advanced diagnostics, improved understanding of pathophysiology may improve our patient care by directly targeting the failed biomechanics of both the pharynx and the esophagus.

The standard treatment of locally advanced type of mid-esophageal cancer is concurrent chemoradiation therapy (CRT). We evaluated the feasibility of chemotherapy with adding docetaxel to the classical basic regimens of cisplatin plus 5-fluorouracil (5-FU) and radiotherapy up to 70.2 Gy using dose escalations for esophageal cancer. It was possible to escalate radiation treatment dose up to 70.2 Gy by the respiratory-gated intensity- modulated radiotherapy (gated-IMRT) based on the 4DCT-simulation, with improving target coverage and normal tissue (ex., lung, heart, and spinal cord) sparing. This study suggested that the definitive chemo-radiotherapy with docetaxel, cisplatin, and 5-fluorouracil (i.e., DCF-R) and gating IMRT is tolerable and active in patients with locally advanced mid-esophageal cancer (AEC)

Over 3 years, concurrent chemoradiotherapy was performed in 16 patients with advanced esophageal cancer (clinical Stage IV) and suspected noncurative resection. The subjects were {>=}A3 or N3, or were stage IV with distant metastasis on preoperative diagnosis. Two courses of 5FU and CDDP were given with concurrent radiotherapy. The predominant side effects were nausea, vomiting and anorexia. Mild or moderate leukopenia also occurred. The response was complete remission (CR) in two patients, partial remission (PR) in eight, minor response (MR) in two, no change (NC) in two and progressive disease (PD) in two. The overall response rate was 62.5%. Esophagectomy was performed in four patients (histological stage II in one, stage III in one, and stage IV in two). Two of 4 resected patients are alive (33.8 months), while the other died of unrelated causes. One of the 6 non-resected PR patients has survived for 18 months, but all other patients died of cancer within nine months of starting treatment. The survival rate of 16 patients undergoing chemoradiotherapy was 16.7% at one and two years. Thus, chemoradiotherapy may improve the prognosis of advanced esophageal cancer with suspected noncurative resection by increasing the response rate and the curative resection rate. (author)

Objective: To evaluate the clinical effect of retrievable esophageal covered metal internal stent in treating patients with achalasia. Methods: Under DSA guidance, peroral 'Z-type' double horn covered metal internal stent implantation was performed in 16 patients with achalasia. Esophagography was carried out about 28 days after the procedure and the stent was retrieved. Results: Of 16 cases, the stent fell off into the stomach two weeks after the operation in one. And the stent was successfully replaced after it was taken out. The placed stent was successfully retrieved in all cases 28 days after the treatment. No serious complications occurred. All the patients were followed up for 3 months to 3 years. During the follow-up period restenosis of the esophagus developed in two cases (at one and 1.5 years respectively), and the restenosis degree was relived after balloon dilation. Clinically, no esophageal symptoms, such as dysphagia, occurred in all patients. Conclusion: As a simple and safe technique, the retrievable esophageal covered metal internal stent implantation is very effective with fewer complications for the treatment of achalasia. Moreover, the technique carries lower restenosis occurrence. (authors)

Case report and review of esophageal lichen planus treated with fluticasone

Lichen planus is a fairly common chronic idiopathic disorder of the skin, nails and mucosal surfaces. Esophageal involvement of this disease on the other hand is rare and only about 50 cases have been reported in literature. Given its rarity, it can be difficult to diagnose and may be easily misdiagnosed as reflux esophagitis. Currently, there are no clear recommendations on the optimal management of this disease and little is known about the best treatment approach. Systemic steroids are usually the first line treatment and offer a favorable response. In this report, we would like to present a novel approach in the management of esophageal lichen planus in a middle-aged woman treated successfully with swallowed fluticasone propionate 220 mcg twice a day for 6 wk, as evidenced by objective clinical findings. Based on our review of related literature and experience in this patient, we feel that a trial of swallowed fluticasone may be a prudent approach in the management of these patients since it has a more favorable side effect profile than systemic treatment.

We analyzed local control, lymph node metastases and distant metastases for autopsy cases of esophageal cancer treated with radiation therapy alone. Thirty-eight patients had squamous cell carcinoma, one had adenosquamous carcinoma and one had undifferentiated carcinoma. Sixteen patients received a total dose less than 60 Gy and 24 received 60 Gy or more. The 1-year, 3-year, 5-year overall survival rates by Kaplan-Meier method were 45.8%, 16.7%, 8.3%, respectively. Four patients (10%) were free of tumors, and another six (15%) had no primary tumor but metastases. Thirty patients had persistent or recurrent primary tumors. Local tumor control rates were 25% for all patients and 34% for patients who survived more than 3 months and 33% for patients irradiated with 60 Gy or more. Tumor type, tumor length and survival times were significantly related with tumor control rates. Perforations into neighboring organs were observed in eighteen patients (45%); 12 were perforated into respiratory systems, 4 into vascular systems, 1 into the mediastinum and 1 into the pleural cavity. Thirty-two patients (80%) had lymph node metastases. Twenty-seven patients (68%) had distant metastases; 20 in the lung, 19 in the liver, 10 in the stomach, 8 in the pancreas and the adrenal gland, 7 in the pleura, 6 in the bone and the heart and the diaphragm. Concurrent double cancer was observed at autopsy in six patients; 2 early gastric cancers, 2 latent hepatomas, 1 lung cancer, 1 latent thyroid cancer. Three patients had a history of resection of other cancer before radiation therapy to esophageal cancer; 2 had gastric cancer and 1 had submandibular cancer. One patient who had another esophageal cancer apart from the first esophageal cancer received radiation therapy 12 years ago. In conclusion, the local control rate was 33% for autopsy cases of esophageal cancer treated with radiation therapy of 60 Gy or more. (J.P.N.)

The aim of this study was to evaluate the efficacy of adjuvant chemoradiotherapy following surgery in patients with advanced esophageal cancer. We followed the cases of 57 such patients treated at our hospital, involving 19 who received adjuvant chemoradiotherapy (CR group), 19 who received radiotherapy alone (R group), and 19 who did received neither (N group). In the CR group, chemotherapy, consisting of cis-diaminodichloroplatinum (CDDP), 5-fluorouracil (5-FU), and etoposide (VP-16), was combined with radiotherapy was administered from 4 weeks after surgery. Concurrent radiotherapy was started at 3 weeks after esophagectomy. CDDP at 50 mg/m{sup 2} was administered on days 1 and 7.5-FU at 500 mg/m{sup 2} and VP-16 at 60 mg/m{sup 2} were administered on days 3, 4, and 5. Thirteen patients (68.4%) were treated with more than 2 cycles of chemotherapy combined with radiation. Side-effects of severe anorexia (grade 3) and leukocytopenia (<1900/{mu}l) were observed in 47% and 39% of the patients, respectively. However no treatment-related death was observed. The 5-year-survival rate was 25.2%, 18.9%, and 15.8%, in the CR group, R group, and N group, respectively. The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no significant difference. These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer. (author)

The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no significant difference. These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer. (author)

Purpose: 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). Methods and Materials: 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. Results: 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

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.

Peroral endoscopic myotomy (POEM) is the application of esophageal myotomy to the concept of natural orifice transluminal surgery (NOTES) by utilizing a submucosal tunneling method. Since the first case of POEM was performed for treating achalasia in Japan in 2008, this procedure is being more widely used by many skillful endosopists all over the world. Currently, POEM is a spotlighted, emerging treatment option for achalasia, and the indications for POEM are expanding to include long-standing, sigmoid shaped esophagus in achalasia, even previously failed endoscopic treatment or surgical myotomy, and other spastic esophageal motility disorders. Accumulating data about POEM demonstrate excellent short-term outcomes with minimal risk of major adverse events, and some existing long-term data show the efficacy of POEM to be long lasting. In this review article, we review the technical details and clinical outcomes of POEM, and discuss some considerations of POEM in special situations. PMID:26717928

Extensive caustic esophageal stricture in children can be treated by serial dilatations interspersed with silicone-covered nitinol stenting

Full Text Available Recurrent esophageal stenosis secondary to caustic ingestion may be challenging to treat. Self-expandable esophageal stents may be an alternative to repetitive endoscopic esophageal dilatation. We report a case of a 2-year-old male child with an extensive esophageal caustic stricture successfully treated using a combination of endoscopic dilatation and stenting. After 5 months of serial balloon dilatations, three nitinol internal silicone covered self-expandable stents were placed through the patient′s gastrostomy spanning the entire esophagus. The stents were positioned using a combination of both endoscopic and fluoroscopic guidance. The procedure was repeated with only one stent 3 months later. A new stricture in the proximal esophagus needed surgical resection and anastomosis, followed by two pneumatic dilatations with progressively longer asymptomatic intervals. The results are promising with the patient able to use his own esophagus; however, this is a single case and optimal stent standing time is still to be determined.

In patients with esophageal cancer who were treated with radiation therapy, esophageal motility was quantitatively analyzed by comparing the findings from esophageal scintigraphy with subjective symptoms and fluoroscopic findings. The subjects of this study were 5 healthy adults and 10 patients with esophageal cancer. Patients with esophageal cancer underwent radiation therapy (exposure to 50 or 60 Gy irradiation). Each subject swallowed 2 mCi of 99m Tc-DTPA, diluted in 20 ml of water, in a sitting position. The upper esophagus, the lower esophagus, the whole esophagus and the cardia were designated as regions of interest (ROI). A time activity curve was obtained for each ROI, followed by calculation of peak transit time (PTT), esophageal emptying time (EET) and gastric peak time (GPT). In healthy adults, PTT, EET and GPT averaged 0.6, 0.6 and 2.9 seconds, respectively. In patients with esophageal cancer, PTT, EET and GPT averaged 1.9, 1.8 and 6.5 seconds, respectively. Thus, mean PTT, EET and GPT were higher in the cancer patients than in the volunteers. In patients who were treated with radiation therapy, the value of the parameters determined by esophageal scintigraphy agreed well with the changes in symptoms. In patients, the smoothness of passage through the esophagus correlated better with the minimum bore of the esophagus than with the length of the narrowed area of the esophageal cancer. The results of this study indicate that esophageal scintigraphy is a useful means of esophageal examination, which allows changes in esophageal motility to be quantitatively assessed easily and physiologically.

Self-expanding metal stents (SEMS) are the treatment of choice for advanced esophageal cancers. Literature is scarce on risk factors predictors for adverse events after SEMS placement. Assess risk factors for adverse events after SEMS placement in advanced esophageal cancer and evaluate survival after SEMS placement. Cross-sectional study of patients with advanced esophageal cancer referred for SEMS placement, during a period of 3 years. Ninety-seven patients with advanced esophageal cancer placed SEMS. Adverse events were more common when tumors were located at the level of the distal esophagus/cardia (47% vs 23%, P = 0.011, OR 3.1), with statistical significance being kept in the multivariate analysis (OR 3.1, P = 0.018). Time until adverse events was lower in the tumors located at the level of the distal esophagus/cardia (P = 0.036). Survival was higher in patients who placed SEMS with curative intent (327 days [126-528] vs. 119 days [91-147], P = 0.002) and in patients submitted subsequently to surgery compared with those who did just chemo/radiotherapy or who did not do further treatment (563 days [378-748] vs. 154 days [133-175] vs. 46 days [20-72], P dysphagia in advanced esophageal cancer and are associated with an increased out-of-hospital survival, as long as there are conditions for further treatments. Tumors located at the level of the distal esophagus/cardia are associated with a greater number of adverse events, which also occur earlier. © 2016 International Society for Diseases of the Esophagus.

2002-01-01

The current status and future prospects of chemoradiation therapy (CRT) for esophageal cancer are reviewed herein. In Western countries, CRT is performed for every stage of esophageal cancer and it has been reported that in definitive CRT series the complete response rate is 30 to 50%, the mean survival rate more than twelve months, and the in 2-year survival rate about 30%, while in neoadjuvant CRT series the pathological response rate is 20 to 50%, the mean survival period more than twenty months, and the 3-year survival 30 to 40%. On the other hand, as esophageal cancer is treated mainly by surgery in Japan, CRT is applied in patients with tumors invading adjacent organs, and a high pathological complete response rate is reported in some neoadjuvant studies. Although both definitive and neoadjuvant CRT increases the response rate and improves local tumor control, CRT is associated with substantial mortality and morbidity, especially in neoadjuvant series. More effective and less toxic CRT regimens, using new chemotherapeutic agents such as nedaplatin and paclitaxel and new irradiation protocol such as accelated hyperfractionation, are needed to improve the prognosis of patients with advanced esophageal cancer.

Objective: To explore the the prognostic significance of MMP-9, uPA and uPAR protein expression and its relationship with clinical-pathologic factors in esophageal squamous cell carcinoma treated by radiotherapy. Methods: MMP-9, uPA and uPAR protein expression was measured in 59 esophageal carcinomas and 41 peri-carcinoma tissues with immunohistochemistry. The relationship between the protein expression and the clinical-pathological parameters was analyzed, and the prognostic factors in esophageal squamous cell carcinoma treated by radiotherapy alone was evaluated. Results: The rates of positive expression of MMP-9, uPA and uPAR were 85%, 76% and 78% in esophageal carcinoma and 39%, 49% and 44% in peri-carcinoma tissues (χ 2 =22.54, 8.04 and 12.18; P=0.000,0.005 and 0.000). The rates of positive expression of MMP-9 was 79% and 100% when the depth of tumor invasion was ≤2 cm and >2 cm(P= 0.048), respectively. The expression of uPA was significantly correlated with the status of fat interspace between the esophageal lesion and the vertebra in CT scanning image. When the fat interspace existed and disappeared, the rates of strong positive expression was 44% and 70%, respectively (χ 2 =4.21, P=0.040). The positive expression rate of uPA was significantly correlated with distant metastasis, which was 100% in patients with distant metastasis and 68.89% in those without distant metastasis(χ 2 =4.12, P=0.042). The positive expression rate of MMP-9, uPA and uPAR did not affect the prognosis and the short-term result of esophageal carcinoma treated by radiotherapy alone. Conclusions: The protein expression of MMP-9, uPA and uPAR may correlate with local infiltration and distant metastasis in esophageal squamous cell carcinoma. Protein expression may not influence the prognosis of esophageal carcinoma treated by radio therapy, though long time followed-up is still needed. (authors)

Esophageal stenosis and/or fistula often occur after chemoradiotherapy (CRT) for unresectable esophageal cancer. In such patients, an esophageal stent can help achieve oral intake. However an esophageal stent cannot be inserted where there is complete stenosis or where the tumor is located. In such cases, esophageal bypass surgery may be necessary. Here, we investigated the clinical characteristics and outcomes in patients who underwent esophageal bypass surgery in our institution. We reviewed 10 cases of esophageal bypass surgery (gastric tube in 8 cases, colon in 2 cases) after CRT for unresectable esophageal cancer, between 2001 and 2009. There were 5 of stenosis-only cases, 4 fistula-only cases, and 1 case of stenosis and fistula. There were postoperative complications in 5 cases (50%), and all these were treated conservatively and healed. The median survival from surgery to peroral intake was 20 days (range 9-90 days), and the median survival after starting peroral intake was 130 days (range 48-293 days). Esophageal bypass surgery can achieve good performance status and improve peroral intake. (author)

A 59-year-old woman was admitted to the hospital with a one-month history of hemoptysis, generalized fatigue, and a high fever. A chest X-ray film obtained on admission showed a massive right-sided pleural effusion. Examination of an aspirate showed a high level of amylase, and bacteria that were the same as oral bacteria. Closed drainage yielded ichorous pus and food residues, which led us to the diagnosis of empyema caused by esophageal perforation. Esophagography and fiberoptic esophagoscopy revealed that an esophagobronchial fistula related to an advanced esophageal carcinoma had caused the empyema. Surgical resection was done, and the patient was alive at the time of this writing, 7 months after she was first treated. Esophageal carcinoma is sometimes accompanied by esophagobronchial fistula. Patients with this condition usually have severe respiratory symptoms; those presenting with empyema are rare. Esophageal carcinoma must be carefully ruled out as the cause of empyema.

Full Text Available Risk factors for squamous cell carcinomas (SCCs of the head and neck (HN and esophagus are similar. As such, synchronous primary tumors in these areas are not entirely uncommon. Definitive chemoradiation (CRT is standard care for locally advanced HNSCC and is a preferred option for inoperable esophageal SCC. Simultaneous treatment of both primaries with CRT can present technical challenges. We report a case of synchronous supraglottic and esophageal SCC primary tumors, highlighting treatment with a monoisocentric hybrid radiation technique and normal tissue toxicity considerations.

Full Text Available 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.

Objective: To study the restorative function of compound white peony root oral liquids (cWPROL) in treating rats' experimental acute radiation-induced esophagitis from the aspect of immunodeficiency. Methods: 128 Wistar rats were divided into eight groups. The radiation esophagitis was induced by 43 Gy 60 Co. Then the rats were treated with medicine in different ways. On every experimental point the absolute number and percentage of T lymphocyte subsets were analyzed by flow cytometry. The changes of the leukocyte in number and differential count were detected by haemocyte counting instrument. IgG and C3 in rats' serum were analyzed by immunological turbidimetry. Results: Radiation brought on decrease of experimental rats 'leukocyte count, the lymphocyte differential count, absolute count and absolute T lymphocyte subsets in the blood and the content of IgG and C3 with radiation esophagitis. cWPROL could increase the lymphocyte percentage compared that in with the radiated group 2. The preventive (high dose) could increase lymphocyte count while Western medicine decreased rats' leukocyte count, lymphocyte percentage and absolute count (P<0.05). The absolute T lymphocyte subsets in rats' peripheral blood increased in the group infused with cWPROL (high dose) (P<0.001). Compared with the radiated group 2 the absolute T lymphocyte subsets decreased significantly(P<0.001), and the content of complement C3 increased in the group infused with cWPROL (high dose) (P<0.05) but decreased in the group infused with Western medicine (P<0.01). Conclusion: cWPROL plays the role of restoring the cytoimmunity and immunity damaged by radiation in rats with radiation esophagitis. (authors)

The purpose of the study was to determine retrospectively whether the extent of dysphagia influenced the survival rate after chemoradiation therapy in patients with advanced esophageal cancer. 46 patients had dysphagia before treatment, in which 39 patients were treated with a combination of chemotherapy and irradiation. The remaining 7 patients were treated with irradiation alone. Forty six patients were divided into 5 groups according to the dysphagia score standard to obtain a relationship between the extent of dysphagia and the survival rate of the patients after treatment. Thirty out of 46 patients (65.2%) became able to swallow solid food after treatment. In these patients, the median survival period was 12 months and the one-year survival rate was 53.2%. However, dysphagia was not improved in 16 patients and their median survival period was 4 months, the one-year survival rate was 17.9%. The survival rate after treatment was definitely higher in the patients with improvement of dysphagia. Regarding esophageal cancer, the patients with cancer in the upper esophagus had the worse survival rate. Improvement of dysphagia was an important factor to control the survival rate after chemoradiation therapy in patients with advanced esophageal cancer. (author)

Background: The 7th edition of the American Joint Committee on Cancer staging system does not include lymph node size in the guidelines for staging patients with esophageal cancer. The objectives of this study were to determine the prognostic impact of the maximum metastatic lymph node diameter (ND) on survival and to develop and validate a new staging system for patients with esophageal squamous cell cancer who were treated with definitive chemoradiotherapy (CRT). Methods: Information on 402 patients with esophageal cancer undergoing CRT at two institutions was reviewed. Univariate and multivariate analyses of data from one institution were used to assess the impact of clinical factors on survival, and recursive partitioning analysis was performed to develop the new staging classification. To assess its clinical utility, the new classification was validated using data from the second institution. Results: By multivariate analysis, gender, T, N, and ND stages were independently and significantly associated with survival (p < 0.05). The resulting new staging classification was based on the T and ND. The four new stages led to good separation of survival curves in both the developmental and validation datasets (p < 0.05). Conclusions: Our results showed that lymph node size is a strong independent prognostic factor and that the new staging system, which incorporated lymph node size, provided good prognostic power, and discriminated effectively for patients with esophageal cancer undergoing CRT.

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

Recent literature on chemoradiotherapy for esophageal cancer report the comparable survival results as surgery, and suggest the importance of management for the late adverse effect of chemoradiotherapy. The aim of this study is to investigate the incidence and risk factors of cardiomegaly after chemoradiotherapy using low dose continuous infusion of 5FU/CDDP+5FU for esophageal cancer. Fifty-one patients with stage I-IVA esophageal cancer who were treated by radiotherapy with more than 50 Gy with or without chemotherapy and followed up for more than 6 months were analyzed. Sixteen patients were treated by radiation alone and 35 patients were treated by chemoradiotherapy. A change of CTR (cardio-thoracic ratio) was defined as the difference between CTR in the pre-treatment X-ray film and CTR in the post-treatment X-ray film with maximum cardiac silhouette. A change of CTR by more than 10% was defined as ''significant cardiomegaly''. In this study cardiac area-dose'', which is the sum of the products of cardiac area within every radiation field and its target dose, was calculated in each patient as a radiation parameter. Significant cardiomegaly was noted in 1 patient (6%) in the radiation alone group, in 8 patients (23%) in the chemoradiotherapy group and in 9 patients (18%) in the total population. In cases with more than 0.4 m{sup 2}{center_dot}Gy in cardiac area-dose, CTR elevation was significantly higher than in cases with less than 0.4m{sup 2}{center_dot}Gy. More than moderate pleural effusion was noted in 5 patients (10%). Chronic pericardial effusion and subsequent cardiac tamponade was considered to be one of the contributing factors for pleural effusion, because increases of pleural effusion coincided with CTR elevations in 3 cases. In addition, the fact that no case had right-sided unilateral pleural effusion suggested the direct effect of radiation to the pleura. Significant cardiomegaly was seen in 18% of 51 patients with

Of 227 esophageal carcinomas treated with a radiation dose of 60 Gy or more, 100 patients had no tumor or ulceration (with or without stenosis) of the esophagus after irradiation. We analyzed local control factors of these 100 patients to determine the need for further treatment. The cumulative local control rate at five years was 40% in all cases, 37% in 21 cases without any stenosis of the esophagus and 40% in 79 cases with stenosis. The presence of stenosis of the esophagus after irradiation was not a critical factor in predicting final local control. Local recurrence of tumors with findings of Borrmann III or Borrmann IV by the pretreatment esophageal barium study, tumors controlled after a total dose of more than 80 Gy, tumors without low dose rate telecobalt therapy (LDRT: 1 Gy/hour, 5 to 7 Gy/day, a total dose of 12 to 15 Gy) as boost therapy, and apparently controlled tumors with a stenotic ratio of 60% or more or with 5 cm or more length of stenosis of the esophagus after irradiation was significantly higher than that of the others (p<0.05). Multivariate analysis revealed that findings of pretreatment barium study, total dose, with or without LDRT, and length of stenosis of the esophagus after irradiation were significantly important factors in local control. Members of the high risk group of apparently controlled tumors should undertake surgical treatment or further intensive chemotherapy. (author)

Esophageal cancer treated by low dose irradiation, crescendo cisplatin and bleomycin polyacrylate pasta

1983-01-01

Eight patients with esophageal cancer were treated by a new treatment schedule consisting of low dose irradiation, crescendo cisplatin and bleomycin polyacrylate pasta. As monitored endoscopically, therapeutic responses were satisfactory : seven out of 8 patients have survived for a range of 3 to 20 months and still active at work or cancer-free. However, one patient suffered from a second malignancy of adenocarcinoma of the upper esophagus different from the initial squamous cell carcinoma at the lower esophagus which had successfully been treated 3 months before. The present therapeutic design aims at treatment of lymphatic spreads in the adjacent structures as well as the original tumor in the esophagus and submucosal invasions. It is basically a consecutive, multimodal integration of selective concentration of therapeutic effects (extensive radiotherapy, topical application of bleomycin polyacrylate pasta, lymphatic chasing with colloidal bleomycin, and spatial concentration of cisplatin as the result of radiation-induced inflammation), perpetuation of the repairable DNA damage, and biological amplifications (protection against esophageal perforation with polyacrylate coating, and specific cancer cell recruitment). Application of the present theraeputic design is being expanded to the treatment of cancer of other specific sites such as the head and neck tumors and rectal cancer with undeniable prospects.

To report our experience with increased dose intensity-modulated radiation and concurrent systemic chemotherapy as definitive treatment of locally advanced esophageal cancer. We analyzed 27 consecutive patients with histologically proven esophageal cancer, who were treated with increased-dose IMRT as part of their definitive therapy. The majority of patients had T3/4 and/or N1 disease (93%). Squamous cell carcinoma was the dominating histology (81%). IMRT was delivered in step-and-shoot technique in all patients using an integrated boost concept. The boost volume was covered with total doses of 56-60 Gy (single dose 2-2.14 Gy), while regional nodal regions received 50.4 Gy (single dose 1.8 Gy) in 28 fractions. Concurrent systemic therapy was scheduled in all patients and administered in 26 (96%). 17 patients received additional adjuvant systemic therapy. Loco-regional control, progression-free and overall survival as well as acute and late toxicities were retrospectively analyzed. In addition, quality of life was prospectively assessed according to the EORTC QLQs (QLQ-OG25, QLQ-H&N35 and QLQ-C30). Radiotherapy was completed as planned in all but one patient (96%), and 21 patients received more than 80% of the planned concurrent systemic therapy. We observed ten locoregional failures, transferring into actuarial 1-, 2- and 3-year-locoregional control rates of 77%, 65% and 48%. Seven patients developed distant metastases, mainly to the lung (71%). The actuarial 1-, 2- and 3-year-disease free survival rates were 58%, 48% and 36%, and overall survival rates were 82%, 61% and 56%. The concept was well tolerated, both in the clinical objective examination and also according to the subjective answers to the QLQ questionnaire. 14 patients (52%) suffered from at least one acute CTC grade 3/4 toxicity, mostly hematological side effects or dysphagia. Severe late toxicities were reported in 6 patients (22%), mostly esophageal strictures and ulcerations. Severe side effects to

We evaluated the clinical effect of 5-FU and low-dose Cisplatin (LFP) therapy alone and LFP therapy combined with radiation therapy in patients with advanced or recurrent esophageal cancer. From March 1995 to September 2000, 11 patients with inoperable esophageal cancer, 8 patients with adjuvant chemotherapy post operation, and 14 patients with recurrent esophageal cancer were treated with LFP therapy. 5-FU (160 mg/m 2 /day) was continuously infused over 24 hours, and CDDP (3-7 mg/m 2 /day) was infused for 30 minutes. The administration schedule consisted of 5-FU for 7 consecutive days and CDDP for 5 days followed by a 2-day rest, each for four weeks. We combined radiation therapy for the patients with all lesions that could be included in the radiation field. Of 30 patients with measurable lesions the response rates of LFP therapy alone and LFP therapy combined with radiation therapy were 33% and 60%, respectively. Toxicity over grade 3 appeared in 3 of 15 patients with LFP therapy combined with radiation therapy. There was no significant difference between LFP therapy alone and LFP therapy combined with radiation therapy with regard to survival rate of inoperable and recurrent esophageal cancer. In conclusion, LFP therapy alone may be effective for esophageal cancer. (author)

Esophageal Achalasia: An Uncommon Complication during Pregnancy Treated Conservatively

2013-01-01

Full Text Available A 38-year-old Caucasian woman, gravida 3 para 2, was admitted at 29 weeks of gestation because of vomiting, dysphagia for solids and liquids, and loss of weight. An enlargement of the anterior left neck region was noted on the palpation of the thyroid gland. An MRI of the neck showed a marked esophageal dilatation with the presence of food remnants along its length and the displacement of the trachea to the right. The findings of the upper gastrointestinal endoscopy and manometry were suggestive of esophageal achalasia. Conservative management with total parenteral nutrition (TPN through a peripheral line proved to be successful. A healthy male baby was born by a cesarean section at 37 weeks. The patient underwent laparoscopic esophageal myotomy and fundoplication seven days postpartum.

Endoscopic Management of Benign Esophageal Strictures.

Science.gov (United States)

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.

Purpose: To optimize the dose of fractionated brachytherapy for palliation of advanced esophageal cancer. Methods and Materials: One hundred and seventy-two patients with advanced esophageal cancer were randomized to receive 12 Gy/2 fractions (group A); 16 Gy/2 fractions (group B), and 18 Gy/3 fractions (group C) by high dose rate intraluminal brachytherapy (HDRILBT). Treatment was given weekly and dose prescribed at 1 cm from the source axis. Patients were followed up monthly and assessed for dysphagia relief and development of complications. Results: Twenty-two patients died before completing treatment due to advanced disease and poor general condition. The overall survival was 19.4% at the end of 12 months for the whole group (A--9.8%, B--22.46%, C--35.32%; p > 0.05). The dysphagia-free survival was 28.9% at 12 months for the whole group (A--10.8%, B--25.43%, C--38.95%; p > 0.05). Forty-three patients developed fibrotic strictures needing dilatation (A--5 of 35, B--15 of 60, C--23 of 55; p = 0.032). Twenty-seven patients had persistent luminal disease (A--11, B--6, C--10), 15 of which progressed to fistulae (A--7, B--2, C--6; p = 0.032). There was no effect of age, sex, race, histology, performance status, previous dilation, presenting dysphagia score, presenting weight, grade, tumor length, and stage on overall survival, dysphagia-free, and complication-free survival (p > 0.05). On a multivariate analysis, brachytherapy dose (p = 0.002) and tumor length (p = 0.0209) were found to have a significant effect on overall survival; brachytherapy dose was the only factor that had an impact on local tumor control (p = 0.0005), while tumor length was the only factor that had an effect on dysphagia-free survival (p = 0.0475). When compared to other forms of palliation currently available (bypass surgery, laser, chemotherapy, intubation, external radiotherapy), fractionated brachytherapy gave the best results with a median survival of 6.2 months. Conclusions: Fractionated

Objective: To compare the long-term quality of life in esophageal carcinoma patients treated with continuous accelerated hyperfractionated (CAHF) and late-course accelerated hyperfractionated (LCAF) radiotherapy. Methods: Subjective and Objective Management Analysis (SOMA) scale, Symptom Checklist 90 (SCL-90) and Life Satisfaction Index A (LSIA) questionnaire were mailed to the long survivors in both CAHF and LCAF groups to assess the long-term quality of life including symptoms, psychological status and life satisfaction. Results: There was no significant difference between the two groups in the score of quality of life such as late radiation reaction, SCL-90 and LSI-A. Conclusions: 1. It is reasonable to assess the quality of life with these scales for esophageal carcinoma patients treated with radiotherapy, 2. Preliminary results demonstrate that there is no significant difference in long-term quality of life between the CAHF and LCAF radiotherapy groups, 3. Methods of evaluating the long-term quality of life for esophageal carcinoma patients treated with radiotherapy needs further investigation, preferably involving more patients and setting on control arm

Managing core temperature is critical to patient outcomes in a wide range of clinical scenarios. Previous devices designed to perform temperature management required a trade-off between invasiveness and temperature modulation efficiency. The Esophageal Cooling Device, made by Advanced Cooling Therapy (Chicago, IL), was developed to optimize warming and cooling efficiency through an easy and low risk procedure that leverages heat transfer through convection and conduction. Clinical data from cardiac arrest, fever, and critical burn patients indicate that the Esophageal Cooling Device performs very well both in terms of temperature modulation (cooling rates of approximately 1.3°C/hour, warming of up to 0.5°C/hour) and maintaining temperature stability (variation around goal temperature ± 0.3°C). Physicians have reported that device performance is comparable to the performance of intravascular temperature management techniques and superior to the performance of surface devices, while avoiding the downsides associated with both.

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.

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 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.

Symptoms relating to esophageal sensory abnormalities can be encountered in the clinical environment. Such sensory abnormalities may be present in demonstrable disease, such as erosive esophagitis, and in the ostensibly normal esophagus, such as non-erosive reflux disease or functional chest pain. In this review, the authors discuss esophageal sensation and the esophageal pain system. In addition, the authors provide a primer concerning the techniques that are available for investigating the autonomic nervous system, neuroimaging and neurophysiology of esophageal sensory function. Such technological advances, whilst not readily available in the clinic may facilitate the stratification and individualization of therapy in disorders of esophageal sensation in the future.

Application of multidisciplinary treatment using chemoradiotherapy (CRT) for advanced esophageal cancer and the problems thereof were examined by stage. Subjects consisted of 169 cases of patients with advanced esophageal cancer who underwent CRT from 1998 to 2004 (stage III/IVa/IVb: 102/55/12 cases). Mean age was 63.4 years old, and male-to-female ratio was 145: 24. In all cases, low dose FP+radiation 40 Gy (4 weeks) was performed. Surgery was performed for resectable cases, and additional irradiation of 20-30 Gy for unresectable cases and those who refused surgery. Considerations included percentage of effectiveness, side effects, and prognosis. Side effects: Low white blood cell (WBC) was 65.1%, esophagitis was 30.2%, anemia was 21.3%, and thrombocytopenia was 12.4%. Stage III: Percentage of effectiveness was 52.0%. Survival rate of 5: 51.0% for resected cases (n=69) and 16.8% for unresected cases (n=33) (p=0.0002). Reasons for unresection: 17 cases of refusal of surgery, 11 cases comprising physical reasons, and 5 cases of others. Stage IVa: The percentage of effectiveness was 45.4%. Survival rate of 5: 23.1% in resected cases (n=13), and 9.8% in unresected cases (n=42). Stage IVb (all cases unresected): The percentage of effectiveness was 25.0%. Survival rate of 1: 11.7%. Survival rate of 2: 0%. In stage III, if prognosis of resected cases after CRT was good and resection was possible after CRT, surgery was desirable. In stage IVa, if it is a single organ T4 case, resection is possible after CRT, which is a good application of CRT. The stage IVb prognosis is poor, so chemotherapy with new regimens should be considered. (author)

Esophageal cancers are highly malignant tumours with often a poor prognosis, except for minimal lesions treated with surgery. Radiation therapy, or combined radiation and chemotherapy is the most used therapeutic modality, alone or before oesophagectomy. The delineation of target volumes is now more accurate owing the possibility to use routinely the new imaging techniques (mainly PET). The aim of this work is to precise the radio-anatomical particularities, the pattern of spread of esophageal cancer and the principles of 3D conformal radiotherapy illustrated with a clinical case.

Full Text Available 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.

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.

In high dose rate intracavitary irradiation for esophageal cancer, the most acceptable dose point is at 5 mm deep from the mucosal surface currently. However, the balloon applicator has a tendency to distort due to irregularity of the tumor, especially advanced cancer. Therefore we studied the difference of the dose distribution when the definition of the mucosal surface was changed in five cases. We concluded that the difference of the distance between the source and the mucosal surface is significant, and the definition of the mucosal surface and mucosal surface dose should also be designated.

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

Discussions are made on local control of 31 cases of esophageal carcinoma which were treated by external and intracavitary irradiation between May 1980 and March 1983. X-ray and endoscopic findings have been used for the image diagnosis. Before the begining of radiotherapy, types of esophageal carcinoma were determined from X-ray findings according to Borrmann's classification. There were 10 cases of types 1 and 2, and 21 cases of types 3 and 4. After completion of external and intracvitary irradiation, all 10 cases of types 1 and 2 were locally controlled. Of the 21 cases of types 3 and 4, 8 cases which developed stenosis or deep ulcer after external irradiation all failed in local control. The remaining 13 cases of types 3 and 4 were locally controlled except 2 by radiotherapy. (author)

Esophageal cancer (EC) is one of common malignant tumors, and the incidence and mortality of EC in China rank the first place in the world. Because of the occult onset, the early atypical symptoms, and the lack of effective early diagnostic methods, most of patients are diagnosed at an advanced stage of the disease and lost the chance of surgery. Comprehensive treatment including palliative medical treatment, molecular targeted therapy, immunotherapy and so on is appropriate for these patients. How to choose the chemotherapy regimen and formulate reasonable treatment plan has become a hot spot in clinical research. Molecular targeted drugs have become a new developmental direction in cancer treatment because of their high specificity and antitumor activity, but the effects on esophageal cancer remain controversial. With the development of immune check point blockade treatment, breakthrough has been made in tumor immunotherapy, which has become an important means in cancer comprehensive treatment and shown a good prospect of treatment.

The prognostic value of supraclavicular lymph node (SCN) metastases in esophageal cancer is not well established. We analyzed the prognostic value of SCN disease in patients after definitive chemoradiation (dCRT) for esophageal cancer. We retrospectively analyzed 207 patients treated between 2003 and 2013 to identify the prognostic value of metastasis in the SCN on treatment failure and survival. All patients were treated with external beam radiotherapy (50.4 Gy in 28 fractions) combined with weekly concurrent paclitaxel 50 mg/m 2 and carboplatin AUC2. Median follow-up for patients alive was 43.3 months. The median overall survival (OS) for all patients was 17.5 months. OS at one, three and five years was 67%, 36% and 21%, respectively. For patients with metastasis in a SCN, OS was 23.6 months compared to 17.1 months for patients without metastasis in the SCN (p = .51). In multivariate analyses, higher cT status, cN status and adenocarcinoma were found to be prognostically unfavorable, but a positive SCN was not (p = .67). Median OS and median disease-free survival for tumors with SCN involvement and N0/1 disease was 49.0 months and 51.6 months, respectively, compared to 14.2 months and 8.2 months, respectively, in patients with N2/3 disease. In esophageal cancer treated with dCRT, the number of affected lymph nodes is an important independent prognostic factor, whereas involvement of a SCN is not. Supraclavicular lymph nodes should be considered as regional lymph nodes and treated with curative intent if the total number of involved lymph nodes is limited.

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.

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

Esophageal carcinoma were treated by high-dose-rate intracavitary irradiation using specially designed balloon application at Hyogo medical Center for Adults. 32 patients were treated from January 1982 through July 1986. According to the stage of UICC (1978), 10 patients were classified into stage I, 7 into II, 13 into III and 2 into IV. Acturial 5 year survival rate was 17.9 % in all 32 patients and that of 23 patients who received radical radiotherapy was 24 %. Local CR rate was 66 %. However, since 9 (53 %) of 17 CR patients were relapsed, local control rate for 2 years was 25 %. Mild adverse effects were experienced in 9 (47 %) of 19 CR patients. Our balloon applicator was easily fixed, could have an adequate space from esophageal mucosa and clarify the tumor site by filling with 20 % gastrografin. It is concluded that high-dose-rate intracavitary irradiation with our balloon applicator is an effective boost therapy and decline a lethal adverse effect in radiotherapy for esophageal carcinoma.

Band ligation (BL) is the most appropriate endoscopic treatment for acute bleeding or prophylaxis of esophageal variceal bleeding. Sclerotherapy with N-butyl-2-cyanoacrylate (CY) can be an alternative for patients with advanced liver disease. Bacteremia is an infrequent complication after BL while the bacteremia rate following treatment with CY for esophageal varices remains unknown. To evaluate and compare the incidence of transient bacteremia between cirrhotic patients submitted to diagnostic endoscopy, CY and BL for treatment of esophageal varices. A prospective study comprising the period from 2004 to 2007 was conducted at Hospital of Universidade Federal de São Paulo, UNIFESP, SP, Brazil. Cirrhotic patients with advanced liver disease (Child-Pugh B or C) were enrolled. The patients were divided into two groups according treatment: BL Group (patients undergoing band ligation, n = 20) and CY Group (patients receiving cyanoacrylate injection for esophageal variceal, n = 18). Cirrhotic patients with no esophageal varices or without indication for endoscopic treatment were recruited as control (diagnostic group n = 20). Bacteremia was evaluated by blood culture at baseline and 30 minutes after the procedure. After 137 scheduled endoscopic procedures, none of the 58 patients had fever or any sign suggestive of infection. All baseline cultures were negative. No positive cultures were observed after CY or in the control group - diagnostic endoscopy. Three (4.6 %) positive cultures were found out of the 65 sessions of band ligation (P = 0.187). Two of these samples were positive for coagulase-negative staphylococcus, which could be regarded as a contaminant. The isolated microorganism in the other case was Klebsiella oxytoca. The patient in this case presented no evidence of immunodeficiency except liver disease. There was no significant difference in bacteremia rate between these three groups. BL or CY injection for non-bleeding esophageal varices may be considered

P53 mutations are an adverse prognostic factor in esophageal cancer. P53 and KRas mutations are involved in chemo-radioresistance. Circulating anti-p53 or anti-KRas antibodies are associated with gene mutations. We studied whether anti-p53 or anti-KRas auto-antibodies were prognostic factors for response to chemoradiotherapy (CRT) or survival in esophageal carcinoma. Serum p53 and KRas antibodies (abs) were measured using an ELISA method in 97 consecutive patients treated at Saint Louis University Hospital between 1999 and 2002 with CRT for esophageal carcinoma (squamous cell carcinoma (SCCE) 57 patients, adenocarcinoma (ACE) 27 patients). Patient and tumor characteristics, response to treatment and the follow-up status of 84 patients were retrospectively collected. The association between antibodies and patient characteristics was studied. Univariate and multivariate survival analyses were conducted. Twenty-four patients (28%) had anti-p53 abs. Abs were found predominantly in SCCE (p = 0.003). Anti-p53 abs were associated with a shorter overall survival in the univariate analysis (HR 1.8 [1.03-2.9], p = 0.04). In the multivariate analysis, independent prognostic factors for overall and progression-free survival were an objective response to CRT, the CRT strategy (alone or combined with surgery [preoperative]) and anti-p53 abs. None of the long-term survivors had p53 abs. KRas abs were found in 19 patients (23%, no difference according to the histological type). There was no significant association between anti-KRas abs and survival neither in the univariate nor in the multivariate analysis. Neither anti-p53 nor anti-KRas abs were associated with response to CRT. Anti-p53 abs are an independent prognostic factor for esophageal cancer patients treated with CRT. Individualized therapeutic approaches should be evaluated in this population

Idiopathic esophageal achalasia is an inflammatory disease of unknown origin, characterized by aperistalsis of the esophageal body and failure of the lower esophageal sphincter in response to swallowing, with consequent dysphagia. To demonstrate the results of surgical therapy in these patients, evaluating the occurred local and systemic complications. Were studied retrospectively 32 patients, 22 of whom presented non-advanced stage of the disease (Stage I/II) and 10 with advanced disease (Stage III/IV). All of them had the clinical conditions to be submitted to surgery. The diagnoses were done by clinical, endoscopic, cardiological, radiological and esophageal manometry analysis. Pre-surgical evaluation was done with a questionnaire based on the most predisposing factors in the development of the disease and the surgical indication was based on the stage of the disease. The patients with non-advanced stages were submitted to cardiomyotomy with fundoplication, wherein in the post-surgical early assessment, only one (4,4%) presented pulmonary infection, but had a good outcome. In patients with advanced disease, seven were submitted to esophageal mucosectomy preserving the muscular layer, wherein one patient (14,2%) presented dehiscence of gastric cervical esophagus anastomosis as well as pulmonary infection; all of these complications were resolved with proper specific treatment; the other three patients with advanced stage were submitted to transmediastinal esophagectomy; two of them presented hydropneumothorax with good evolution, and one of them also presented fistula of the cervical esophagogastric anastomosis, but with spontaneous healing after conservative treatment and nutritional support. The two patients with fistula of the cervical anastomosis progressed to stenosis, with good results after endoscopic dilations. In the medium and long term assessment done in 23 patients, all of them reported improvement in life quality, with return to swallowing. The

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.

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

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.

Objective: To evaluate clinical value of self-expanded covered stents for advanced stage esophageal cancer complicated by esophageal stricture and esophagus-bronchial fistula. Methods: Self-expanded covered stents were placed into 48 patients with advanced stage esophageal cancer under fluoroscopy. Of the 48 patients, 39 had malignant esophageal stricture and 9 had esophagus-bronchus fistula. Results: Stents were successfully inserted into all but one patient with lower esophageal cancer and gastric volvulus. Deglutition was improved in all patients and coughing resolved in patients with esophagus-bronchus fistula. Thoracodynia and foreign body sensation vanished within one week after operation in all patients. Dyspnea caused by compression of the left main bronchus occurred in one patient. Re-stenosis of the stents occurred three to seven months after operation in eight patients. The mean survival time was seven months in all patients. Conclusion: Self-expanded covered stent placement is a simple, safe and reliable treatment method for advanced stage esophageal cancer and can effectively lengthen survival time. (authors)

Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival. A total of 110 patients with mid-thoracic ESCC who suffered from Ivor-Lewis were enrolled. The CEP55 expression profile of these patients in tumour tissues and corresponding healthy esophageal mucosa (CHEM) was detected by immunohistochemistry and semi-quantitative reverse transcription-polymerase chain reaction analyses. Correlations between CEP55 expression and clinicopathological factors were analyzed using χ 2 test. The log-rank test was employed to calculate survival rate. A Cox regression multivariate analysis was performed to determine independent prognostic factors. The results demonstrated that CEP55 expression in ESCC was significantly higher than that of CHEM (POverexpression of CEP55 was significantly associated with differentiation degree (P=0.022), T stage (P=0.019), lymph node metastasis (P=0.033), clinicopathological staging (P=0.002) and tumor recurrence (P=0.021) in locally advanced ESCC patients. In addition, CEP55 overexpression was significantly associated with reduced overall survival of patients after surgery (P=0.012). The 5-year survival rate of patients without CEP55 overexpression was significantly higher than that of patients with CEP55 overexpression (P=0.012). Therefore, these findings suggest that CEP55 overexpression correlates with poor prognosis in locally advanced ESCC patients.

Infants and children with esophageal atresia commonly present with swallowing dysfunction or dysphagia. Dysphagia can lead to a range of significant consequences such as aspiration pneumonia, malnutrition, dehydration, and food impaction. To improve oral intake, the clinical diagnosis of dysphagia in patients with esophageal atresia should focus on both the pharynx and the esophagus. To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagu...

Alpha-fetoprotein (AFP)-producing esophageal adenocarcinoma (EAC) is a rare occurrence. Elevation of serum AFP is commonly associated with hepatocellular carcinoma and yolk sac tumors, but rarely with esophageal carcinoma. Here, we report a rare case of AFP-producing EAC. A 51-year-old man presented with two weeks of acid reflux and a 35-lb weight loss. Laboratory data were notable for transaminitis and AFP was 2524 ng/mL. Computed tomography of the abdomen revealed abnormal thickening of the esophagus and multiple metastatic masses throughout the liver. Biopsy of one of the masses revealed adenocarcinoma of gastrointestinal origin. Subsequent upper endoscopy revealed an esophageal mass with biopsy notable for ulcerated dysplastic glandular mucosa with likely underlying malignancy. The patient underwent palliative esophageal stent placement but died two months later. Elevated AFP levels are an unusual occurrence in EAC. Prognosis is poor given its advanced presenting stage and high metastatic potential. Most cases are unsuccessfully treated with surgery and chemotherapy. Serial measurement of serum AFP may be useful for monitoring clinical status and treatment response. Clinicians should consider AFP-producing EAC in their differential diagnosis in the work-up of a liver mass in the setting of elevated AFP or liver function impairment, especially in the absence of chronic liver disease.

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.

Balloon dilatation has been applied in treating of various pathologic narrowing of the hollow viscus. It is now accepted as a very effective modality especially in treating esophageal stenosis obviating surgical procedure. We performed 128 balloon dilatations in 29 patients with the number of dilatations in each patient ranging from once to 12 times. The age distribution of the patients was from 3 weeks to 6 years, with the median age of 3 months. Twenty nine patients consisted of 25 postoperative esophageal strictures (21 esophageal atresia with tracheoesophageal fistula, 1 congenital esophageal stenosis, 2 tracheobronchial remnant, and 1 congenital esophageal stenosis with esophageal atresia), 2 achalasia, 1 congenital esophageal stenosis, and 1 corrosive esophagitis. We had successful dilatation in 22 patients, who showed subsequent relief of symptoms and improvement in the diameter of stenotic segment. In 14 patients, esophageal perforation occurred during the procedure, one requiring emergency thoracotomy and the other three conservative management. Seven patients had no improvement in stenotic sites after several balloon dilatations. Failed cases were congenital stenosis, achalasia, corrosive esophagitis and four postoperative strictures. We believe that balloon dilatation is the procedure of choice in the treatment of postoperative esophageal stricture in infants and children and is a safe method as the perforation which can complicate the procedure could be managed conservatively.

We evaluated esophageal peristalsis in patients with esophageal tumors by cine MR using steady-state free precession (SSFP) sequence and correlated the alteration of the esophageal peristalsis with clinical symptoms and tumor stages. Thirteen patients with pathologically proven esophageal tumors, including 12 esophageal cancers and one submucosal leiomyoma, underwent cine MRI using true fast imaging with steady precession (trueFISP) sequence, which is one SSFP sequence, after contrast-enhanced MR scanning for clinical purposes. A total of 120 serial images were obtained within 60 s through the plane along the long axis of the esophagus while patients chewed gum. The serial trueFISP images were evaluated for the presence, frequency, speed of progression, and passage of peristalsis through the tumor. The data from cine MRI were compared with clinical symptoms and tumor stages. Peristalsis was clearly identified in all patients. Seven patients with complete interruption of peristalsis had dysphagia; one with partially impaired peristalsis could intake solid foods with discomfort; and two with partially impaired peristalsis and three with preserved peristalsis remained asymptomatic. Patients with complete or partial interruption of peristalsis had Stage T3 or T4 esophageal cancer. In conclusion, trueFISP cine MR imaging enables direct visualization of esophageal peristalsis in relation to esophageal tumors. Complete interruption of peristalsis causes dysphagia, whereas partial interruption of and preserved peristalsis usually do not cause digestive problems. Interruption of peristalsis may indicate impaired muscle function caused by invasion of advanced esophageal cancers. (author)

Esophageal motility in eosinophilic esophagitis.

Science.gov (United States)

Weiss, A H; Iorio, N; Schey, R

2015-01-01

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

2010-01-01

Objective: To provide a reference for determination of the postoperative radiotherapy target volume for thoracic esophageal squamous cell carcinoma. Background data: The irradiation target volume is important for effective postoperative treatment of thoracic esophageal squamous cell carcinoma. Methods: One hundred forty patients with recurrent or metastatic thoracic esophageal squamous cell carcinoma who had been treated with radical surgery but not with postoperative radiotherapy were enrolled in this study. The information of locoregional recurrence and distant metastasis for these patients was analyzed. Results: The median time to progression in the 140 patients with recurrence or metastasis was 18.3 months (range 15.4-21.1 months). Anastomotic recurrence accounted for 13.6% of treatment failures. The supraclavicular and station 1-5 and 7 lymph nodes had high metastasis rates for esophageal squamous cell carcinomas in all locations. The order from highest to lowest metastasis rate for the station 3 and 4 lymph nodes was middle, upper and lower thoracic esophageal regions and the order for upper abdominal lymph nodes was lower, middle, and upper thoracic esophageal regions. Locoregional recurrence was the most common type of recurrence. Conclusions: For upper and middle thoracic esophageal squamous cell carcinomas, the anastomosis, supraclavicular, and station 1-5 and 7 lymph nodes should be delineated as the postoperative prophylactic irradiation target volume with upper abdominal lymph nodes excluded; for lower thoracic esophageal squamous cell carcinomas, anastomosis, supraclavicular, station 1-5 and 7 lymph nodes and upper abdominal lymph nodes should be delineated as the postoperative prophylactic irradiation target volume.

1995-03-01

From 1/1985 to 7/1993, 18 patients underwent endoscopic photodynamic therapy (PDT) for early stage esophageal squamous cell carcinoma -- as two patients had two synchronous esophageal cancers, 20 lesions were treated. Tumors were staged as Tis in 7 cases and T1 in 13. The average light energy delivered was 50 J/cm2 and 70 J/cm2 for the treatment of Tis and T1, respectively. To obtain a more uniform distribution of laser light in 12 cases the irradiation was performed through the wall of a transparent tube previously placed over the endoscope and advanced into the stomach. The overall results show a complete response in 14/20 (70%) tumors. Three patients developed a local recurrence, 6, 12, and 14 months after therapy. After a follow-up of 5 to 75 months, there was no evidence of disease in 10/18 patients (56%). The actuarial survival rate was 95%, 79%, and 26% at 1, 3, and 5 years, respectively. Complications were skin reaction in one patient and esophageal stenosis at the treatment site, that gradually responded to endoscopic bougienage, in 2 patients. Endoscopic PDT proved to be safe and effective in the treatment of superficial carcinoma of the esophagus.

Full Text Available Mucormycosis is a rare invasive fungal infection with high mortality. It usually affects patients with poorly controlled diabetes, immunosuppression, or hematological malignancies. Gastroenterologists need to be aware of this rare infection because endoscopy can facilitate early diagnosis and prompt appropriate therapy. Here we describe a case of invasive esophageal mucormycosis that developed in a 63-year-old man with diabetes, acute promyelocytic leukemia, and prolonged leukopenia after chemotherapy. Upper endoscopy showed distal circumferential esophageal wall thickening with devitalization. The mucosa did not bleed after endoscopic biopsy. Histopathology confirmed mucormycosis. He was treated with various antifungal agents including echinocandins, fluconazole, and liposomal amphotericin B. Despite aggressive antifungal therapy and supportive care, the patient died 24 days later.

Ninety-eight patients with esophageal cancer were treated by high dose rate intraluminal radiation therapy at the Department of Radiology of the Hyogo Medical Center for Adults between January 1982 and December 1993. Twenty patients with complete response after intraluminal radiation therapy, who were followed up with esophageal fiberscopy in our institute, were reviewed. The one-year cumulative rate of occurrence of esophageal ulcers was 81%, and in 69% of the cases the ulcers occurred from 4 to 8 months after completion of intraluminal radiation therapy. We graded esophageal ulcer by fiberscopic findings. Grade 0 was defined as no ulcer, grade 1 as superficial ulcer, grade 2 as deep ulcer, grade 3 as circumferencial ulcer, and severe stenosis. Factors related to grade were studied, and shorter distances from the source to the surface of the mucosa and lower surface doses of intraluminal radiation therapy appear to reduce the severity as graded on the above scale, of the esophageal ulcer. Four of the five 2-year recurrence-free patients suffered esophageal ulcers, which were cured from 15 to 22 months after intraluminal radiation therapy. However ulcers recurred in two patients, ong term care was thought to be necessary. (author)

Esophageal Cancer: Insights from Mouse Models

Directory of Open Access Journals (Sweden)

Marie-Pier Tétreault

2015-01-01

Full Text Available Esophageal cancer is the eighth leading cause of cancer and the sixth most common cause of cancer-related death worldwide. Despite recent advances in the development of surgical techniques in combination with the use of radiotherapy and chemotherapy, the prognosis for esophageal cancer remains poor. The cellular and molecular mechanisms that drive the pathogenesis of esophageal cancer are still poorly understood. Hence, understanding these mechanisms is crucial to improving outcomes for patients with esophageal cancer. Mouse models constitute valuable tools for modeling human cancers and for the preclinical testing of therapeutic strategies in a manner not possible in human subjects. Mice are excellent models for studying human cancers because they are similar to humans at the physiological and molecular levels and because they have a shorter gestation time and life cycle. Moreover, a wide range of well-developed technologies for introducing genetic modifications into mice are currently available. In this review, we describe how different mouse models are used to study esophageal cancer.

The protocol and result were described of chemotherapy and radiotherapy for locally advanced esophageal carcinoma, especially for A3 stage one with metastasis at neighboring tissues such as aorta, trachea and bronchia. Chemotherapy was done with 5-FU and CDDP and radiotherapy, with 30 Gy/15 fx/3 wk. Double contrast roentgenography, dynamic CT and MRI were performed to follow the process. The efficacy rate was 55.0% with 4 CR and 7 PR in 20 cases. Three CR patients survived at present. Major adverse effects were leukopenia and thrombocytopenia, of which grade 4 were found in 14 and 12% cases, respectively. Low-dose FP therapy might be useful for lowering the adverse effects and for elevating the efficacy rates. (K.H.)

We conducted a pilot study of nedaplatin+5-fluorouracil (5-FU) combined with radiotherapy for 29 patients with primary advanced (stage IV) esophageal cancer. A complete remission (CR) was obtained in 4 (14%) and a partial response in 13 patients (response rate: 59%). The median survival time and one-year survival rate were 238 days and 34.5%, respectively. Of the 29 patients, 24 (83%) completed the treatment schedule and toxicity of stomatitis and the like was infrequent. In conclusion, these results suggest that the efficacy of nedaplatin+5-FU combined with radiotherapy might not differ from that of cisplatin+5-FU combined with radiotherapy. Clearly, the usefulness of this combined therapy needs to be assessed in multicenter phase III trials. (author)

The prognosis of the patients with advanced esophageal carcinoma treated by definitive radiotherapy is still dismal with a reported 5-year survival rate of 5-10% in most series. Since 1986, combined radiotherapy with chemotherapy using platinum analogue was initiated at Asahikawa and Obihiro Kosei Hospitals in order to improve local-regional control and the survival of the patients. From 1980 to 1992, 81 patients with unresectable esophageal carcinoma were treated with radiotherapy. Since April 1986, 37 out of the 81 patients received both radiotherapy and chemotherapy with platinum. Platinum was used during the course of radiotherapy. The method of administration of platinum was as follows; Cisplatin intravenously (50 mg, weekly, total 200 mg) in 9 patients, Carboplatin intravenously (100-150 mg, weekly, total 400-900 mg) in 11 patients and Cisplatin intraarterially (100 mg, at a 3-4 week interval, total 100-300 mg) in 17 patients. These 37 patients (Group A) were compared to 44 patients treated by radiotherapy alone (Group B) with respect to initial response and survival rate. Response was defined according to the guidelines recommended by Japanese Society for Esophageal Diseases. Response rates were 59.1% (19 CR and 7 PR) in Group B and 70.3% (7 CR and 19 PR) in Group A. Primary relapse-free rates were 36.4% in Group B and 37.8% in Group A. The cumulative survival at 3 years were 11.7% in Group B and 10.6% in Group A. Enhancement of side effects by chemotherapy was minimal and acceptable. Improvement of local-regional control and survival was not obvious by adding a concomitant platinum-chemotherapy. A definite conclusion, however, could not be drawn because of the retrospective, non-controlled nature of this study. Introduction of more intensive, multiple agents chemotherapy seems necessary if one aims at improving the results. (author)

To retrospectively analyze the patterns of failure and the treatment effects of involved-field irradiation (IFI) on patients treated with locally advanced esophageal squamous cell carcinoma (ESCC) and to determine whether IFI is practicable in these patients. A total of 79 patients with locally advanced ESCC underwent three dimensional conformal (3D)CRT) or intensity modulated radiotherapy (IMRT) using IFI or elective nodal irradiation (ENI) according to the target volume. The patterns of failure were defined as local/regional, in-field, out)of)field regional lymph node (LN) and distant failure. With a median follow)up of 32.0 months, failures were observed in 66 (83.6%) patients. The cumulative incidence of local/regional failure (55.8 vs 52.8%) and in)field regional lymph node failure (25.6 vs 19.4%) showed no statistically significant difference between the IFI and the ENI group (p=0.526 and 0.215, respectively). Out)of)field nodal relapse rate of only 7.0% was seen in the IFI group. Three)year survival rates for the ENI and IFI group were 22.2 and 18.6%, respectively (p=0.240), and 3)year distant metastasis rates were 27.8 and 32.6%, respectively (p=0.180). The lung V10, V20, V30 and mean lung dose of the ENI group were greater than those of the IFI group, while the mean lung dose and V10 had statistically significant difference. The patterns of failure and survival rates in the IFI group were similar as in the ENI group; the regional recurrence and distant metastasis are the main cause of treatment failure. IFI is feasible for locally advanced ESCC. Further investigation is needed to increase local control and decrease distant metastasis in these patients.

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.

Full Text Available Cicatricial pemphigoid (CP is a rare blistering autoimmune disease. Esophageal involvement occurs in widespread disease and rarely appears as the only affected organ. We report a 67-year-old Caucasian female with esophageal dysphagia and weight loss. Several oral panendoscopies showed multiple exudative ulcerations with fibrin and webs in mid- and proximal esophagus and a peeling mucosa. There were no lesions in other organs. We established the diagnosis performing a direct immunofluorescence (DIF, demonstrating IgG3 and complement deposition along the basement membrane. As initial treatment the patient received prednisone 60 mg and 1 gr twice daily of mycophenolate mofetil (MMF as a steroid-sparing agent due to its lower toxicity and its selective mechanism of action. Six months later there was a significant clinical improvement and the esophageal ulcerations had disappeared, developing cicatricial fibrous rings, although no stenosis was present. Four years later, the patient remains asymptomatic with a low maintenance dose of MMF.

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.

The purpose of this study was to assess the toxicity and efficacy of multimodal approaches, including three-dimensional conformal re-irradiation, for patients with recurrent or persistent esophageal cancer after radiotherapy. Thirty-one patients with esophageal cancer treated with three-dimensional conformal re-irradiation were retrospectively analyzed. Of the 31 patients, 27 patients received concurrent chemotherapy, and 14 patients underwent regional hyperthermia during the re-irradiation. We divided the patients into two groups on the basis of their clinical condition: the curative group (n=11) or the palliative group (n=20). Severe toxicities were detected in one patient with Grade 3 esophageal perforation in the curative group, and 5 patients had a Grade 3 or higher toxicity of the esophagus in the palliative group. Advanced T stage at the time of re-irradiation was found to be significantly correlated with Grade 3 or higher toxicity in the esophagus. For the curative group, 10 (91%) of 11 patients had an objective response. For the palliative group, symptom relief was recognized in 8 (57%) of 14 patients with obvious swallowing difficulty. In conclusion, in the curative group with early-stage recurrent or persistent esophageal cancer, the multimodal approaches, including three-dimensional conformal re-irradiation, may be feasible, showing acceptable toxicity and a potential value of promising results, although further evaluations especially for the toxicities of the organs at risk are required. In the palliative group, the benefit of our therapy may be restrictive because severe esophageal toxicities were not uncommon in the patients with advanced T stage at the time of re-irradiation.

Chemotherapy has been shown to be most effective when delivered concurrently with radiation for patients with untreated advanced-stage tumors. We conducted a concurrent chemoradiation protocol using systemic infusion of Cisplatin (CDDP) and 5-Fluorouracil (FU), followed by radical surgery. Thirty-six patients with advanced hypopharyngeal (n=28) or cervical esophageal cancer (n=8) received intravenous administration of CDDP (100 mg/m 2 ), followed by a 120-hour continuous infusion of 5-FU (1000 mg/m 2 /day), and concomitant radiotherapy (200 cGy/day x 20-35 fractions). One patient died of aspiration pneumonia. The rate of grade 3-4 hematological chemotoxicity was 27.8% (10/36). Pharyngo-laryngo-cervical esophagectomies were performed in 23 patients, one received partial resection of the hypopharynx, and one received radical neck dissection. Ten remaining patients refused radical surgery. In the resected specimens, 11 out of 24 (46%) were confirmed as complete response (CR). The median length of follow-up was 74.5 weeks. The projected 5-year survival was 39.7%. When the patients who had refused radical surgery for residual tumor were excluded, the 5-year survival rate rose up to 70.0% in the patients with hypopharyngeal cancer. Concurrent chemoradiotherapy can be safely and effectively applied. Preliminary pathological results indicate the possibility in improving the rate of organ preservation. (author)

Eosinophilic esophagitis in patients with esophageal atresia and chronic dysphagia.

2014-12-21

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.

Esophageal Dysmotility, Gastro-esophageal Reflux Disease, and Lung Transplantation: What Is the Evidence?

Science.gov (United States)

Wood, Richard K

2015-12-01

Lung transplantation is an effective and life-prolonging therapy for patients with advanced lung disease (ALD). However, long-term patient survival following lung transplantation is primarily limited by development of an inflammatory and fibrotic process involving the lung allograft known as bronchiolitis obliterans syndrome (BOS). Although the precise cause of BOS remains uncertain and is likely multifactorial, chronic aspiration of gastro-duodenal contents is one possible contributing factor. Multiple small, cross-sectional studies performed over the past two decades have reported a high prevalence of gastro-esophageal reflux disease (GERD) and esophageal dysmotility in the ALD population and several investigations suggest the prevalence may increase following lung transplantation. More recent studies evaluating the direct effect of gastro-duodenal contents on airways have demonstrated a possible biologic link between GERD and BOS. Despite the recent advances in our understanding of BOS, further investigations are needed to establish GERD as a causative factor in its development. This review will discuss the existing literature that has identified an association of GERD with ALD and post-transplant populations, with a focus on recent advances in the field.

Methods: This study retrospectively evaluated 202 patients with locally advanced ESCC treated at Shandong Cancer Hospital between January 2009 and December 2013. All the patients initially received dCRT, including platinum and paclitaxel or 5-fluorouracil, with concurrent 1.8 or 2 Gy/fraction radiation (total dose, 54–60 Gy. The patient population was divided into two treatment groups: 105 patients who received the cisplatinum/paclitaxel regimen were allocated to group A, and 97 patients who received the cisplatinum/5-fluorouracil regimen were allocated to group B. We compared the progression-free survival (PFS and overall survival (OS by various clinical variables, including prior treatment characteristics, major toxicities (mainly in grade 3 and 4 hematological, and response to dCRT. We used the receiver operating curve analysis to determine the optimal cutoff value of clinical stage and radiation dose. The Kaplan–Meier method was used for survival comparison and Cox regression for multivariate analysis. Results: Median PFS and OS in group A were significantly better compared with group B (median PFS, 15.9 versus 13.0 months, P=0.016 and median OS, 33.9 versus 23.1 months, P=0.014, respectively.

Full Text Available Background. Since neoadjuvant treatment in esophageal cancer began to become popular, a complete pathological response at the primary tumour site has been commonly reported. An issue of conflict is whether complete response in the esophageal lumen means that the esophagus is completely tumour-free. Another important issue is whether lymph nodes that are retrieved from pathologically complete response cases are also tumour-free or not. There is a gap in the esophageal cancer staging system for ypT0 N2 M0 tumours that have received neoadjuvant therapy. Here, we will discuss the problem about staging of esophageal cancer associated with neoadjuvant therapy. Case. A female aged 40 years complaining of dysphagia was diagnosed as having locally advanced thoracic esophageal cancer. Neoadjuvant therapy decision was taken by oncology committee. Six weeks after neoadjuvant therapy, with a curative intention, minimal invasive surgery was performed. The pathology report was as follows. “There were no neoplastic cells in the suspected area of the esophageal mucosa upon examination with all staining. There was no cancer at resection margins. Four metastatic lymph nodes were infiltrated with squamous cell cancer.” Conclusion. Despite the growing use of neoadjuvant treatment in locally advanced esophageal cancer in world, we do not have a protocol for the evaluation of these patients’ pathology reports. We believe that new studies and new ideas are needed to resolve this dilemma associated with neoadjuvant therapy.

It has been reported that proton beam therapy is an effective treatment method for patients with locally confined esophageal cancer. However, there seems to be serious problems related to post-radiotherapy (RT) esophageal ulcers. We treated 7 patients who developed post-RT esophageal ulcers with the earliest symptom of esophageal stenosis, which was observed 7-17 months (median, 10.0) after completion of RT. Five of the patients had unhealed ulcers leading to lethal events such as perforation or penetration. The mean time between the appearance of the earliest symptom and lethal episode was no more than 2 months (mean, 2.1). The first 3 patients who underwent conservative therapies died from severe complications caused by perforation or penetration of post-RT esophageal ulcers. In the case of 2 consecutive patients, we performed surgical treatment as soon as possible since there were indications of penetration in post-RT developed esophageal ulcers. Therefore, they could be cured by a salvage operation which was subtotal esophagectomy using the stomach for esophageal replacement. Through the above-mentioned experience, we discussed surgical management for esophageal ulcers after proton beam therapy. (author)

Full Text Available Esophagitis dissecans superficialis and eosinophilic esophagitis are distinct esophageal pathologies with characteristic clinical and histologic findings. Esophagitis dissecans superficialis is a rare finding on endoscopy consisting of the peeling of large fragments of esophageal mucosa. Histology shows sloughing of the epithelium and parakeratosis. Eosinophilic esophagitis is an allergic disease of the esophagus characterized by eosinophilic inflammation of the epithelium and symptoms of esophageal dysfunction. Both of these esophageal processes have been associated with other diseases, but there is no known association between them. We describe a case of esophagitis dissecans superficialis and eosinophilic esophagitis in an adolescent patient. To our knowledge, this is the first case describing an association between esophageal dissecans superficialis and eosinophilic esophagitis.

Treatments for esophageal cancer. A review

International Nuclear Information System (INIS)

Kato, Hiroyuki; Nakajima, Masanobu

2013-01-01

Esophageal cancer is the eighth most common form of cancer worldwide. The treatments for esophageal cancer depend on its etiology. For mucosal cancer, endoscopic mucosal resection and endoscopic submucosal dissection are standard, while for locally advanced cancer, esophagectomy remains the mainstay. The three most common techniques for thoracic esophagectomy are the transhiatal approach, the Ivor Lewis esophagectomy (right thoracotomy and laparotomy), and the McKeown technique (right thoracotomy followed by laparotomy and neck incision with cervical anastomosis). Surgery for carcinoma of the cervical esophagus requires an extensive procedure with laryngectomy in many cases. When the tumor is more advanced, neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy is added. The theoretical advantages of adding chemotherapy to the treatment of esophageal cancer are potential tumor down-staging prior to surgery, as well as targeting micrometastases and, thus, decreasing the risk of distant metastasis. Cisplatin- and 5-fluorouracil-based regimes are used worldwide. Chemoradiotherapy is the standard for unresectable esophageal cancer and could also be considered as an option for resectable tumors. For patients who are medically or technically inoperable, concurrent chemoradiotherapy should be the standard of care. Although neoadjuvant chemoradiotherapy followed by surgery or salvage surgery after definitive chemoradiotherapy is a practical treatment; judicious patient selection is crucial. It is important to have a thorough understanding of these therapeutic modalities to assist in this endeavor. (author)

Esophageal resection in patients with esophageal cancer (EC) is still associated with high mortality and morbidity rates. We aimed to develop a simple preoperative risk score for the prediction of short-term and long-term outcomes for patients with EC treated by esophageal resection. In total, 498 patients suffering from esophageal carcinoma, who underwent esophageal resection, were included in this retrospective cohort study. Three preoperative esophagectomy risk (PER) groups were defined based on preoperative functional evaluation of different organ systems by validated tools (revised cardiac risk index, model for end-stage liver disease score, and pulmonary function test). Clinicopathological parameters, morbidity, and mortality as well as disease-free survival (DFS) and overall survival (OS) were correlated to the PER score. The PER score significantly predicted the short-term outcome of patients with EC who underwent esophageal resection. PER 2 and PER 3 patients had at least double the risk of morbidity and mortality compared to PER 1 patients. Furthermore, a higher PER score was associated with shorter DFS (P PER score was identified as an independent predictor of tumor recurrence (hazard ratio [HR] 2.1; P PER score allows preoperative objective allocation of patients with EC into different risk categories for morbidity, mortality, and long-term outcomes. Thus, multicenter studies are needed for independent validation of the PER score.

Surgery is still the best way for treatment of esophageal cancer. The increase in life expectancy and the rising incidence of esophageal tumors have led to a great number of elderly candidates for complex surgery. The purpose of this study was to evaluate the effects of advanced age (70 years or more) on the surgical outcome of esophagectomy for esophageal cancer at a single high-volume center. Between January 2000 and April 2006, 480 cases with esophageal cancer underwent esophagectomy in the referral cancer institute. One hundred sixty-five patients in the elderly group (70 years old or more) were compared with 315 patients in the younger group ( 0.05). With increased experience and care, the outcomes of esophagectomy in elderly patients are comparable to young patients. Advanced age alone is not a contraindication for esophagectomy. (author)

1986-01-01

So far there is still considerable disagreement as to the evaluation of the pre- and postoperative irradiation effects on the survival rate of the patients with esophageal carcinoma. From April 1973 to December 1983, 138 cases of thoracic esophageal carcinoma were surgically operated upon at our Department; 68 cases were irradiated and 70 cases were not irradiated prior to the surgical operation. Followup study was done and its result has been reported in this communication. A few cases treated by pre-operative irradiation survived longer than the expected longevity in spite of their low curative operation rates. Prognosis was better in the cases with well differentiated squamous cell carcinoma, when marked or good responses to pre-operative irradiation with the calculated total dose of 30 Gy were recorded. There were differences in responsibility in the various histological types of esophageal carcinomas; good response in the group of well differentiated squamous carcinoma, less marked response in the groups of moderately and poorly differentiated squamous carcinomas, minor response in the types of undifferentiated and unclassifed carcinomas. From our observation it seems reasonable to say that prognosis of the patients with pre- and postoperative irradiation was better than that of those who received postoperative irradiation only.

Full Text Available To investigate the recent trends in definitive management of esophageal cancer, the records of 138 consecutive patients treated with radical intent in a single institution between 1995 and 2003 were reviewed and analyzed. The median follow-up period was 5.7 years (range 1.1 to 10.4 years. Seventy-seven patients were treated with radiation therapy (RT only and 61 with combined regimens (CRT, in which RT was combined with either radical surgery or chemotherapy, or both. The overall survival of the entire cohort was 32% over two years and 20% over five years. The survivorship in the RT group was 17% over two years and 5% over five years. In the CRT group, 51% and 35% survived over two and five years, respectively. From all the potential prognostic factors examined by univariate and multivariate analyses, only male sex and use of CRT were strongly associated with better survivorship. There was no significant difference in the outcomes among the different regimens of CRT. Survivorship was not affected by the location or histology of the tumour, clinical stage, dose of RT or use of endoluminal brachytherapy in addition to external beam RT. There was a greater tendency to use RT only more often in older patients, but patient age did not affect survivorship. The proportion of patients treated with CRT did not change significantly over the last versus the first four years of the observed period. Combined regimens are undoubtedly superior to RT as a single modality. The long-term survivorship of patients in a subgroup of our patients treated with combined modality protocols compared favourably with the previously reported results in the literature and specifically in prospective randomized trials. However, the optimal combined modality regimen is yet to be defined.

The aim of this study was to evaluate the medium-term outcome (health status, medical and surgical French National Health Authority-recommended follow-up, and quality of life) of children born with type III esophageal atresia (EA). Previous events (during the perinatal period, associated abnormalities, respiratory and digestive complications) of children treated for type III EA at the Marseille university hospitals between 1999 and 2009 were noted. Parents completed a standardized questionnaire concerning the health of their children during the previous year, and a quality-of-life questionnaire (PedsQL 4.0) was also completed by children aged more than 8 years. Among the 68 children treated, 44 responded to our solicitation (mean age, 7.6 years; range, 3-12.8 years). Previous important events were : pneumonia(s) (65%), asthma before the age of 3 years (66%), hospitalization for a respiratory event (45%), fundoplication (20%), and esophageal dilatation (45%). We noted current chronic cough (16%), asthma (30%), dysphagia (39%), and symptomatic gastroesophageal reflux (9%). National guidelines were not respected, except for the surgical indications in children aged less than 6 years. The quality-of-life scores (n=43 children) were similar to healthy controls but were negatively influenced by a gastrostomy procedure (P=0.020), pneumonia (P=0.013), and hospitalization due to a respiratory event (P=0.006) or a digestive event (P=0.010), and also by current asthma (P=0.004). In conclusion, despite recurrent respiratory or digestive symptoms and inadequate recommended follow-up, the quality of life of children treated for type III of EA is good. Copyright © 2013.

The allergic response associated with eosinophilic esophagitis (EoE) occurs when food antigens permeate tight junction-mediated epithelial dilated intercellular spaces. We assessed whether levels of tight junction proteins correlate with the dilation of intercellular spaces (spongiosis) and the effects of topical steroids on these parameters. We assessed esophageal biopsy samples from 10 patients with active EoE treated with topical fluticasone, 10 untreated patients, and 10 patients without esophageal disease (controls) for degree of spongiosis. Immunohistochemical assays were used to determine the levels of the tight junction proteins filaggrin, zonula occludens (ZO)-1, ZO-2, ZO-3, and claudin-1. Histology and immunohistochemistry results were assessed blindly, with levels of tight junction proteins and degree of spongiosis rated on scales of 0 to 3. The mean degrees of spongiosis in untreated and treated patients with EoE were 1.3 and 0.4, respectively (P = .016). Esophageal epithelia did not stain significantly for ZO-1 or ZO-2. Filaggrin was observed in a predominant cytoplasmic pattern, compared with the cytoplasmic and membranous patterns of ZO-3 and claudin-1. In biopsy specimens from patients with active EoE, the mean staining intensities for filaggrin, ZO-3, and claudin-1 were 1.6, 1.4, and 0.7, respectively. In biopsy specimens from patients treated with fluticasone, levels of filaggrin, ZO-3, and claudin-1 were 2.8 (P = .002 compared with untreated patients), 1.7 (P = .46 compared with untreated patients), and 1.3 (P = .25 compared with untreated patients), respectively. The correlation between the level of filaggrin and the degree of spongiosis was r = 0.23, and between ZO-3 staining and the degree of spongiosis was r = .016 (P = .001 for filaggrin vs ZO-3 staining). Filaggrin, ZO-3, and claudin-1 (but not ZO-1 or ZO-2) are detected in the esophageal mucosa of patients with EoE treated with steroids and individuals without esophageal disease

Cyclosporine in the Management of Esophageal Lichen Planus

Full Text Available Lichen planus (LP is an uncommon disorder of unknown etiology, mostly affecting patients in their fifth and sixth decade of life. It is believed to be an autoimmune process involving T cells directed against basal keratinocytes. It affects the skin, nails, oral pharynx and genitals. Esophageal involvement is quite rare and can cause strictures, ulcerations and squamous cell cancer. The present article describes the case of a 54-year-old woman who was referred for assessment of dysphagia that initially occurred with solids, which then progressed to soft foods but spared liquids. The patient reported a weight loss of 9.1 kg. An esophagogastroduodenoscopy was performed and she was subsequently diagnosed with pill esophagitis. At the same time, she was also diagnosed with oral LP, with no involvement of the esophagus. She was treated with a proton pump inhibitor that resolved her gastrointestinal symptoms. The symptoms returned one year later and a repeat esophagogastroduodenoscopy revealed white plaques due to LP. She was treated with intermittent glucocorticoids. Diagnosis of esophageal LP is crucial for the proper treatment. Some patients may require systemic immunosuppression and mechanical dilation to prevent weight loss. Surveillance endoscopies should be performed to monitor for squamous cell cancer. Cyclosporine has been used for genital and oral LP, but the present case is the first in which it has been used successfully to treat esophageal LP.

Chemotherapy combined with radiotherapy can improve outcome in locally advanced esophageal cancer. This study aimed to compare efficacy and toxicity between concurrent chemoradiotherapy (CCRT) and sequential chemoradiotherapy (SCRT) in unresectable, locally advanced, esophageal squamous cell carcinoma (ESSC). Forty-one patients with unresectable, locally advanced ESCC were randomized into two arms. In the CCRT arm (Arm A), 17 patients received 50.4 Gy at 1.8 Gy per fraction over 5.6 weeks along with concurrent cisplatin (75 mg m(-2) intravenously on day 1 and 5-fluorouracil (1000 mg m(-2) continuous intravenous infusion on days 1-4 starting on the first day of irradiation and given after 28 days. In the SCRT arm (Arm B), 20 patients received two cycles of chemotherapy, using the same schedule, followed by radiotherapy fractionated in a similar manner. The endpoints were tumor response, acute and late toxicities, and disease-free survival. With a median follow up of 12.5 months, the complete response rate was 82.4% in Arm A and 35% in Arm B (P = 0.003). Statistically significant differences in frequencies of acute skin toxicity (P = 0.016), gastrointestinal toxicity (P = 0.005) and late radiation pneumonitis (P = 0.002) were found, with greater in the CCRT arm. A modest but non-significant difference was observed in median time to recurrence among complete responders in the two arms (Arm A 13 months and Arm B 15.5 months, P = 0.167) and there was also no significant difference between the Kaplan Meier survival plots (P = 0.641) of disease-free survival. Compared to sequential chemoradiotherapy, concurrent chemoradiotherapy can significantly improve local control rate but with greater risk of adverse reactions.

Esophageal heterotopic gastric mucosa in esophageal atresia

2018-05-01

Full Text Available Heterotopic gastric mucosa (HGM is occasionally found at endoscopy in the proximal esophagus of adults and children, when it manifests as an asymptomatic small island of reddish pink mucosa just below the upper esophageal sphincter. There are few reports of esophageal HGM detected by endoscopy after repair of esophageal atresia (EA with tracheo-esophageal fistula (TEF. We report a child with multiple patches of HGM in the proximal and distal esophagus seen at endoscopy after EA/TEF repair. No obvious symptoms were related to the HGM and she remains under endoscopic surveillance. The incidence of esophageal HGM may be increased in patients with EA and its distribution can be more extensive than a simple “inlet patch”. There is evidence to suggest that esophageal HGM increases the risk of developing Barrett's esophagus and has a malignant potential. Heterotopic gastric mucosa extends the spectrum of potential pathologies affecting the esophagus in patients with EA/TEF and supports current international guidelines for endoscopic surveillance of these patients.

2016-01-01

A 74-year-old man admitted with dysphagia was found to have advanced esophageal squamous cell carcinoma, clinical stage 4 (T4N2M0). We initiated definitive chemoradiotherapy (dCRT) with combined 5-fluorouracil and cisplatin chemotherapy (FP therapy) and 50.4 Gy irradiation, followed by boost FP therapy, to which the patient showed confirmed complete response (CR). Local recurrence was detected in the scar of the primary lesion at 4 months after the boost FP therapy. Photodynamic therapy (PDT) for this lesion resulted in CR. Thirteen months later, right hilar and right pericardial lymph node metastases were found. The right hilar lymph node metastases were not visible on CT after triweekly docetaxel therapy, but the pericardial lesions remained. The patient underwent salvage lymphadenectomy without further chemotherapy, and at 5 months after surgery, he was alive and recurrence-free. (author)

Secondary Prevention of Esophageal Squamous Cell Carcinoma in Areas Where Smoking, Alcohol, and Betel Quid Chewing are Prevalent

Directory of Open Access Journals (Sweden)

2010-06-01

Full Text Available Esophageal cancer is ranked as the sixth most common cause of cancer death worldwide and has a substantial effect on public health. In contrast to adenocarcinoma arising from Barrett's esophagus in Western countries, the major disease phenotype in the Asia-Pacific region is esophageal squamous cell carcinoma which is attributed to the prevalence of smoking, alcohol, and betel quid chewing. Despite a multidisciplinary approach to treating esophageal cancer, the outcome remains poor. Moreover, field cancerization reveals that esophageal squamous cell carcinoma is closely linked with the development of head and neck cancers that further sub-optimize the treatment of patients. Therefore, preventive strategies are of paramount importance to improve the prognosis of this dismal disease. Since obstacles exist for primary prevention via risk factor elimination, the current rationale for esophageal cancer prevention is to identify high-risk groups at earlier stages of the disease, and encourage them to get a confirmatory diagnosis, prompt treatment, and intensive surveillance for secondary prevention. Novel biomarkers for identifying specific at-risk populations are under extensive investigation. Advances in image-enhanced endoscopy do not just substantially improve our ability to identify small precancerous or cancerous foci, but can also accurately predict their invasiveness. Research input from the basic sciences should be translated into preventive measures in order to decrease the disease burden of esophageal cancer.

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 stents have been used to palliate patients with dysphagia caused by esophageal cancer. Early rigid plastic prostheses have been associated with a high risk of complications. However, with the development of self-expanding stents, it has developed into a widely accepted method for treating malignant esophageal strictures and esophagorespiratory fistulas (ERFs). The present review covers various aspects of self-expanding metallic stent placement for palliating esophageal cancer, including its types, placement procedures, indications, contraindications, complications, and some of innovations that will become available in the future. © 2017 The Korean Academy of Medical Sciences.

Esophageal cancer (EC) is increasing in prevalence due to rising incidence and improved treatment strategies. Dysphagia is a significant morbidity in patients with EC requiring nutritional intervention. We sought to evaluate outcomes of nutritional interventions for EC patients hospitalized with dysphagia at a population level. The National Inpatient Sample (2002-2012) was utilized to include all adult inpatients (≥18 years of age) with EC and presence of dysphagia and stricture that underwent nutritional interventions including feeding tube (FT) placement, esophageal stenting, or parenteral nutrition (PN). Temporal trends were examined with multivariate analysis performed for mortality, length of stay (LOS), and cost of hospitalization. A total of 509,593 EC patients had 12,205 hospitalizations related to dysphagia. The hospitalization rates doubled over the study period (1.52% vs. 3.28%, p esophageal stenting (13%), and PN (11%). PN was more frequently associated with a diagnosis of sepsis (6.1%, p = 0.023) compared to FT (2.5%) or esophageal stenting (1.8%). Multivariate analysis demonstrated FT and esophageal stenting had comparable mortality (OR 1.06, 95% CI: 0.49, 2.32); however, PN was associated with higher mortality (OR 2.37, 95% CI: 1.22, 4.63), cost of hospitalization ($5,510, 95% CI: 2,262, 8,759), and LOS (2.13 days, 95% CI: 0.72, 3.54). This study shows that hospitalizations for EC with dysphagia and related nutritional interventions are increasing. As a single modality, parenteral nutrition should be avoided. Among our esophageal stent and FT population, further studies are necessary to determine adequate interventions based on disease stage. © The Authors 2017.

We report clinico-pathological studies on the effect of preoperative hyperthermia and chemotherapy combined with radiotherapy (HCR) for progress of the local curability of advanced esophageal carcinoma. The subjects of these studies were 17 patients who underwent subtotal esophagectomy after preoperative irradiation of 40 Gy from 1980 to 1989, of which 8 patients had HCR, 6 patients irradiation only (R), 3 patients both irradiation and chemotherapy (CR). The clinical response rate of the patients with R or CR was 33% (PR 3, MR 3, NC 3), and the histological effective (Ef{sub 3} or Ef{sub 2}) rate was 56% (Ef{sub 3} 1, Ef{sub 2} 4, Ef{sub 1} 4). The clinical response rate of the patients with HCR was 88% (PR 7, MR 1), and the histological effective rate was 100% (Ef{sub 3} 1, Ef{sub 2} 7). HCR was more effective than R or CR for the local lesion of esophageal carcinoma histopathologically (p<0.05). However, the survival rate of patients with HCR was similar to R and CR, respectively. These results suggest that further improvement of the heating methods and the methods of combining hyperthermia with irradiation and chemotherapy is needed. (author).

To evaluate the clinical efficacy of balloon catheter dilatation in the treatment of esophageal achalasia. Seven patients(three males and four females) with esopha-geal achalasia were treated with balloon catheter dilatation. Balloon catheters of variable sizes were used depending on patient's conditions. The patients were followed up over a period of 12-39 months. Balloon catheter dilatation in esophageal achalasia was successful in all patients without esophageal perforation. All patients were relieved from dysphagia. Recurrence was not found in 5 patients on long term follow-up study, but was seen in 2 patients after 18 and 21 months, respectively. Balloon catheter dilatation was a safe and effective method in the treatment of esophageal achalasia with low recurrence rate of 29% on follow-up study.

1996-01-01

During an 11-year period, a group of 130 patients with esophageal cancer of stages 2 to 4 were treated with external beam irradiation (40 to 60 Gy) followed by boost dose of 10 to 20 Gy of high-dose intracavitary brachytherapy. The overall 2-year survival rate was 15.4%. The significant prognostic factors were tumor size, response to external beam irradiation, pretreatment dysphagia score, and presence of distant metastases. The palliative effect was excellent; the dysphagia scores of 122 of 130 patients (93.8%) improved. The significant palliative factors were response to external beam irradiation and pretreatment dysphagia score. Tracheoesophageal fistulas developed after treatment in 13 of 130 patients (10%); 3 of the fistulas were probably related to radiotherapy. We conclude that intracavitary brachytherapy is useful in the treatment of cases of advanced cancer which show a good response to external beam irradiation and may be curative in patients with mild dysphagia.

Surgical resection has been traditionally the mainstay of treatment for localized esophageal cancers. However, survival after surgery alone for advanced esophageal cancer is not satisfactory. In Japan, the development of multimodal therapy for esophageal cancers has centered mainly on systemic chemotherapy plus surgery to control distant metastasis. Based on the results of the recent Japan Clinical Oncology Group (JCOG) 9907 study, preoperative chemotherapy (consisting of 5-fluorouracil (FU) and cisplatin) followed by surgery has emerged as the standard treatment. In Western countries, where chemoradiotherapy followed by surgery has been mainly explored for patients with resectable esophageal cancers, two large controlled trials that evaluated the effectiveness of preoperative chemotherapy reported conflicting results. However, a recent meta-analysis reported significant survival benefits for preoperative chemotherapy in patients with adenocarcinoma of the esophagus. We need to find new effective preoperative chemotherapeutic regimens, including molecular target agents, with response rates higher than that of the conventional chemotherapy of 5-FU and cisplatin. However, we also must compare the survival benefits of preoperative chemotherapy with preoperative chemoradiotherapy. (author)

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 (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.

Puropose: Palliative radiotherapy is an effective technique to alleviate systems of disease burden in late-stage lung cancer patients. Previous randomized controlled studies demonstrated a survival benefit in patients with good performance status at radiation doses of 35Gy10 or greater but with an increased incidence of esophagitis. The objective of this planning study was to assess the potential impact of esophageal-sparing IMRT (ES-IMRT) compared to the current standard of care using parallel-opposed pair beams (POP). Methods: In this study, 15 patients with lung cancer treated to a dose of 30Gy in 10 fractions between August 2015 and January 2016 were identified. Radiation treatment plans were optimized using ES-IMRT by limiting the max esophagus point dose to 24Gy. Using published Lyman-Kutcher-Burman normal tissue complication probabilities (LKB-NTCP) models, both plans were evaluated for the likelihood of esophagitis (≥ grade 2) and pneumonitis (≥ grade 2). Results: Using ES-IMRT, the median esophageal and lung mean doses reduced from 16 and 8Gy to 7 and 7Gy, respectively. Using the LKB models, the theoretical probability of symptomatic esophagitis and pneumonitis reduced from 13 to 1%, and from 5 to 3%, respectively. The median NTD mean for the GTV and PTV of the clinically approved POP plans compared to the ES-IMRT plans were similar. Conclusions: Advanced radiotherapy techniques such as ES-IMRT may have clinical utility in reducing treatment-related toxicity in advanced lung cancer patients. Our data suggests that the rate of esophagitis can be reduced without compromising tumour control.

Impaired esophageal motor function in eosinophilic esophagitis.

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.

We tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD). Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms. Individuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3-5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6-2.7, P = 0.63). Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly. © 2014 Asian Pacific Society of Respirology.

Esophageal microbiome in eosinophilic esophagitis.

Directory of Open Access Journals (Sweden)

J Kirk Harris

Full Text Available The microbiome has been implicated in the pathogenesis of a number of allergic and inflammatory diseases. The mucosa affected by eosinophilic esophagitis (EoE is composed of a stratified squamous epithelia and contains intraepithelial eosinophils. To date, no studies have identified the esophageal microbiome in patients with EoE or the impact of treatment on these organisms. The aim of this study was to identify the esophageal microbiome in EoE and determine whether treatments change this profile. We hypothesized that clinically relevant alterations in bacterial populations are present in different forms of esophagitis.In this prospective study, secretions from the esophageal mucosa were collected from children and adults with EoE, Gastroesophageal Reflux Disease (GERD and normal mucosa using the Esophageal String Test (EST. Bacterial load was determined using quantitative PCR. Bacterial communities, determined by 16S rRNA gene amplification and 454 pyrosequencing, were compared between health and disease.Samples from a total of 70 children and adult subjects were examined. Bacterial load was increased in both EoE and GERD relative to normal subjects. In subjects with EoE, load was increased regardless of treatment status or degree of mucosal eosinophilia compared with normal. Haemophilus was significantly increased in untreated EoE subjects as compared with normal subjects. Streptococcus was decreased in GERD subjects on proton pump inhibition as compared with normal subjects.Diseases associated with mucosal eosinophilia are characterized by a different microbiome from that found in the normal mucosa. Microbiota may contribute to esophageal inflammation in EoE and GERD.

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 was 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

Full Text Available Abstract Background Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. Case presentation A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. Conclusion We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

Purpose: The strategy of definitive chemoradiation with selective surgical salvage in locoregionally advanced esophageal cancer was evaluated in a Phase II trial in Radiation Therapy Oncology Group (RTOG)-affiliated sites. Methods and Materials: The study was designed to detect an improvement in 1-year survival from 60% to 77.5% ({alpha} = 0.05; power = 80%). Definitive chemoradiation involved induction chemotherapy with 5-fluorouracil (5-FU) (650 mg/mg{sup 2}/day), cisplatin (15 mg/mg{sup 2}/day), and paclitaxel (200 mg/mg{sup 2}/day) for two cycles, followed by concurrent chemoradiation with 50.4 Gy (1.8 Gy/fraction) and daily 5-FU (300 mg/mg{sup 2}/day) with cisplatin (15 mg/mg{sup 2}/day) over the first 5 days. Salvage surgical resection was considered for patients with residual or recurrent esophageal cancer who did not have systemic disease. Results: Forty-three patients with nonmetastatic resectable esophageal cancer were entered from Sept 2003 to March 2006. Forty-one patients were eligible for analysis. Clinical stage was {>=}T3 in 31 patients (76%) and N1 in 29 patients (71%), with adenocarcinoma histology in 30 patients (73%). Thirty-seven patients (90%) completed induction chemotherapy followed by concurrent chemoradiation. Twenty-eight patients (68%) experienced Grade 3+ nonhematologic toxicity. Four treatment-related deaths were noted. Twenty-one patients underwent surgery following definitive chemoradiation because of residual (17 patients) or recurrent (3 patients) esophageal cancer,and 1 patient because of choice. Median follow-up of live patients was 22 months, with an estimated 1-year survival of 71%. Conclusions: In this Phase II trial (RTOG 0246) evaluating selective surgical salvage after definitive chemoradiation in locoregionally advanced esophageal cancer, the hypothesized 1-year RTOG survival rate (77.5%) was not achieved (1 year, 71%; 95% confidence interval< 54%-82%).

Purpose: In reported retrospective non-randomized trials of treatment of esophageal carcinoma, blacks have a lower survival from esophageal cancer than whites. None of these studies has accounted for the extent of disease, or the methods and quality of treatment. We reviewed the data that included only patients treated on the chemoradiation arm of the RTOG-8501 esophageal carcinoma trial to see if there were differences in overall survival between black and white patients receiving the same standard of care. Methods and Materials: One hundred-nineteen patients, 37 blacks and 82 whites were evaluated who met the criteria for receiving chemoradiation of 5000 cGy and four courses of Cisplatin (75 mg/m 2 ) and Fluorouracil (1000 mg/m 2 for 4 days). Results: Blacks had squamous histology only, with 86% of blacks having weight loss of 10 lbs. or more compared to 56% of whites (p = 0.001). In addition, blacks had larger tumors and more difficulty eating (p = 0.010). Overall, there was no difference in the Kaplan-Meier median survival estimate by race (p = 0.2757). Only when we limited the analysis to the 'squamous histology' subgroup, stratified according to age >70 vs. 70 years) did poorly. Because of the dramatic differences in the age and histology distributions between blacks and whites, this issue could not be resolved in the subset of squamous only who received chemoradiation. Conclusions: The increasing incidence of adenocarcinoma among white patients without a corresponding increase of this histology in blacks reflects a difference in diet and or lifestyle compared to blacks that deserves additional study. When treated aggressively with chemoradiation, race did not appear to be a statistically significant factor for overall survival

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

A Patterns of Care Study examined the records of patients with thoracic esophageal cancer treated with radiotherapy and surgery in 1995 through 1997. Thirty-one percent of patients received preoperative radiotherapy; 61% of these received chemotherapy. Sixty six percent of patients received postoperative radiotherapy. Significant variables for overall survival in multivariate analysis include presence of macroscopic residual tumors (risk ratio=2.66), sex female (0.49), photon energy higher than 4 MV (0.50), Karnofsky performance status greater than 70 (0.55) and the use of chemotherapy (1.64). The value of preoperative concurrent chemotherapy and radiotherapy should be tested in a randomized trial. (author)

Esophageal cancer is the sixth most common cancer in male causing death worldwide. It is usually diagnosed at advanced stage with high postoperative recurrence and systemic metastasis, which leads to poor prognosis. The potential inhibitory effect of herbal medicines on metastasis of esophageal cancer has drawn researchers’ great attention. In the present study, the anti-invasion activities of Andrographis paniculata (AP) have been evaluated in two esophageal cancer cell lines, EC-109 and KYSE-520, as well as human microvascular endothelial cells (HMEC-1). The anti-tumor and anti-metastatic activities of AP were also evaluated in human esophageal xenograft-bearing mouse models. Our results demonstrated for the first time that aqueous extract of AP inhibited the motility and invasion of esophageal cancer cells, which is the initial step of metastasis, without cytotoxicity. Anoikis resistance has also been reversed in AP-treated cancer cells. Besides, the expression of metastasis-related gene TM4SF3 in EC-109 cells was significantly decreased in AP extract-treated cells in a concentration-dependent manner. Furthermore, the anti-tumor and anti-metastatic efficacies in subcutaneous and intraperitoneal esophageal xenograft-bearing mice were demonstrated after oral administration of AP aqueous extract for 3 weeks. Last but not least, the active component, isoandrographolide, responsible for the anti-migratory activity was firstly revealed here. In conclusion, the AP aqueous extract exerted inhibitory activities on the migration and anoikis resistance of esophageal cancer cells EC-109 and KYSE-520, as well as suppressed the proliferation and motility of endothelial cells. Combining the mentioned effects may account for the anti-tumor and anti-metastasis effects of AP aqueous extract in xenograft-bearing mice. The findings in the present study further enhance the understanding of the therapeutic mechanisms of the herb AP, which may lead to clinical applications. PMID

Impaired esophageal motor function in eosinophilic esophagitis

Directory of Open Access Journals (Sweden)

Cecilio Santander

2015-10-01

Full Text Available 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.

Full Text Available Esophageal carcinosarcoma is a rare malignant neoplasm consisting of both carcinomatous and sarcomatous components. It is generally treated by surgery, radiotherapy and chemotherapy according to the protocols used for other esophageal cancers. However, the treatment of esophageal carcinosarcoma by radiotherapy alone before surgery has not been previously described. We report a patient with a rapidly growing esophageal carcinosarcoma that was efficiently reduced by neoadjuvant radiotherapy alone. A previously healthy 69-year-old man was admitted with dysphagia. Initial esophagogastroduodenoscopy (EGD revealed a small nodular polypoid lesion of about 10 mm in the middle esophagus. A second EGD 1 month later showed that the tumor had expanded into a huge mass. A biopsy specimen revealed that the tumor comprised squamous cell carcinoma with spindle cell components, and the tumor was diagnosed as carcinosarcoma which was diagnosed as stage I (T1bN0M0. Due to renal dysfunction, the patient was treated with neoadjuvant radiotherapy (40 Gy without chemotherapy. A third EGD 1 month later revealed remarkable tumor reduction. He then underwent total esophagectomy with regional lymph node dissection (pStage 0, pT1aN0M0. After surgical operation, the patient was followed up without adjuvant therapy. Whole body computed tomography revealed lung metastasis 14 months after surgery, and the patient died 2 months later. The neoadjuvant radiotherapy for esophageal carcinosarcoma was considered to have contributed to the subsequent surgery and his prolonged survival time. Thus, radiotherapy alone might be a suitable neoadjuvant therapy for esophageal carcinosarcomas.

Esophageal motility was evaluated from the analysis of 10 consecutive swallows using liquid bolus containing 0.5 mCi of {sup 99m}Tc tin colloid. We have reviewed our experience of esophageal transit study in the 20 normal volunteers and 55 patients with dysphagia that was not related to mechanical obstruction. The purpose of this study is to measure the esophageal transit in normal subjects and in patients with various esophageal motility disorders. The overall sensitivity and specificity of radionuclide esophageal transit study in detecting esophageal motor abnormality were compared with manometric results as a gold standard, which were 80% and 100% respectively. Radionuclide transit study is a safe, rapid, noninvasive test and suitable as a screening test for esophageal motor disorders.

Full Text Available Introduction. Gastrointestinal stromal tumors of the esophagus are rare. Case Presentation. This is a case of a 50-year-old male patient who was referred to our department complaining of atypical chest pain. A chest computed tomographic scan and endoscopic ultrasound revealed a submucosal esophageal tumor measuring 5 cm in its largest diameter. Suspecting a leiomyoma, we performed enucleation via right thoracotomy. The pathology report yielded a diagnosis of an esophageal gastrointestinal stromal tumor. The patient has shown no evidence of recurrence one year postoperatively. Conclusions. This report illustrates the complexity and dilemmas inherent in diagnosing and treating esophageal GISTs.

Esophageal Rupture as a Primary Manifestation in Eosinophilic Esophagitis

Directory of Open Access Journals (Sweden)

Natalia Vernon

2014-01-01

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

Esophageal cancer is one of the leading causes of mortality among the neoplasms that affect the gastrointestinal tract. There are several factors that contribute for development of an epidemiological esophageal cancer profile in a population. This study aims to describe both clinically and epidemiologically the population of patients with diagnosis of esophageal cancer treated in a quaternary attention institute for cancer from January, 2009 to December, 2011, in Sao Paulo, Brazil. The charts of all patients diagnosed with esophageal cancer from January, 2009, to December, 2011, in a Sao Paulo (Brazil) quaternary oncology institute were retrospectively reviewed. Squamous cell cancer made up to 80% of the cases of esophageal cancer. Average age at diagnosis was 60.66 years old for esophageal adenocarcinoma and 62 for squamous cell cancer, average time from the beginning of symptoms to the diagnosis was 3.52 months for esophageal adenocarcinoma and 4.2 months for squamous cell cancer. Average time for initiating treatment when esophageal cancer is diagnosed was 4 months for esophageal adenocarcinoma and 4.42 months for squamous cell cancer. There was a clear association between squamous cell cancer and head and neck cancers, as well as certain habits, such as smoking and alcoholism, while adenocarcinoma cancer showed more association with gastric cancer and gastroesophageal reflux disease. Tumoral bleeding and pneumonia were the main causes of death. No difference in survival rate was noted between the two groups. Adenocarcinoma and squamous cell carcinoma are different diseases, but both are diagnosed in advanced stages in Brazil, compromising the patients' possibilities of cure.

Objective: To evaluate clinical effectiveness and influence factors in the treatment of benign and malignant esophageal stenosis by placing esophageal stent. Methods: A series of this research comprised of 29 cases with esophageal cancer, 10 cardiac carcinoma, 5 cardiac achalasia, 6 benign esophageal stricture after operation. The lengths of lesion ranged from 2 to 14 cm in length with mean of 7.3 cm. Fistula were found among malignant esophageal stenosis in 6 cases. According to the dysphagia scores, 12 cases were designated at I grade, 31 with II, and 14 with III. 46 cases of malignancy were undertaken radiation therapy combined with transcatheter arterial chemotherapy from 15 to 30 days after stent placement. Results: 62 stents were placed in 57 cases (52 domestic stents, 10 Boston ultraflex), including 4 cases with 2 stents being once placed, 1 case with second time stent placement because of restenosis 4 month later. All stents were placed successfully without serious complications, such as esophageal perforation, massive hemorrhage. 5 cases of cardiac achalasia and 6 cases of benign esophageal stricture are still alive now. The survival rates of 6, 12, 24 and 36 months in 46 malignant cases, were 67.4%(31/46), 43.5%(20/46), 26.1%(12/46), and 19.6(9/46) respectively. Dysphagia were relieved significantly from 7 to 15 days after stent placement. Conclusions: Esophageal stent placement combined with radiation therapy and transcatheter arterial chemotherapy could improve patient life qualities and survival rates significantly in malignant stricture. The effects on benign esophageal stricture by stent placement are comparable with that of surgical treatment

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.

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.

Esophagectomy, one of the most invasive of all gastrointestinal operations, is associated with a high frequency of postoperative complications and in-hospital mortality. The purpose of the present study was to determine whether exposure to the atomic bomb explosion at Hiroshima in 1945 might be a preoperative risk factor for in-hospital mortality after esophagectomy in esophageal cancer patients. We thus reviewed the outcomes of esophagectomy in 31 atomic bomb survivors with esophageal cancer and 96 controls (also with cancer but without atomic bomb exposure). We compared the incidences of postoperative complications and in-hospital mortality. Of the clinicopathological features studied, mean patient age was significantly higher in atomic bomb survivors than in controls. Of the postoperative complications noted, atomic bomb survivors experienced a longer mean period of endotracheal intubation and higher incidences of severe pulmonary complications, severe anastomotic leakage, and surgical site infection. The factors associated with in-hospital mortality were exposure to the atomic bomb explosion, pulmonary comorbidities, and electrocardiographic abnormalities. Multivariate analysis revealed that exposure to the atomic bomb explosion was an independent significant preoperative risk factor for in-hospital mortality. Exposure to the atomic bomb explosion is thus a preoperative risk factor for in-hospital death after esophagectomy to treat esophageal cancer. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

Dynamic esophageal scintigraphy

Esophageal scintigraphy was developed in order to quantitatively evaluate esophageal transit in patients with a variety of esophageal disorders. The study is performed with orally administered technetium-99m sulfur colloid in water, using a gamma camera on-line to a digital computer. Esophageal transit is expressed as the percent emptying for each of the first 15-sec intervals for 10 min after an initial swallow and at 15-sec intervals after serial swallows. Esophageal transit is significantly decreased in patients with motor disorders of the esophagus, compared to normal controls. In patients with reflux esophagitis, esophageal transit was abnormal when the reflux disease was accompanied by abnormal motor function. The technique we describe is the first quantitative test of esophageal function; it is a useful, sensitive, scintigraphic technique for evaluation of esophageal transit

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.

Chronic gastrointestinal symptoms are commonly reported in autistic patients. Dysphagia is often present, and it is generally related to behavioral eating disorders. The association between autism and esophageal achalasia has not been described in literature yet. We report our experience with three cases of autistic children we recently treated for esophageal achalasia. In the first case (a 14-year-old male), achalasia was diagnosed with barium swallow and esophageal manometry and was successfully treated with three pneumatic endoscopic dilatations (follow-up: 3 years). In the second case (a 12-year-old female), achalasia was diagnosed with barium swallow and esophageal manometry and was treated with Heller myotomy after two unsuccessful pneumatic endoscopic attempts (follow-up: 3 months). In the last case, a 15-year-old male underwent barium swallow and endoscopy that confirmed achalasia. He was treated with Heller myotomy, and he is asymptomatic at a 6-month follow-up. To our knowledge, this is the first report of a possible association between autism and esophageal achalasia. Because of the rarity of both diseases, their association in the same patient is unlikely to be casual even if speculation on their common etiology is impossible at present. This finding needs further confirmation, but it is sufficient, in our opinion, to indicate proper evaluation with barium swallow and/or manometry in any autistic children with eating difficulty. © 2012 Copyright the Authors.

Yamada, Shogo; Kakuto, Yoshihisa; Sakamoto, Kiyohiko

1994-01-01

Ninety-one fresh autopsied esophageal carcinomas treated with a radiation dose of more than 40 Gy were analyzed, because no primary tumor with under 40 Gy was controlled. There were no residual tumors in 6.6% of the patients. Radiation controlled 28.6% of the locoregional tumors. The local control rate was higher in patients with a tumor length under 5 cm. Metastasis was detected in 76.9% of all the patients. Twenty patients (22.0%) had no primary tumor but metastases. The most common sites of metastasis were the lymph node, lung and liver. Multivariate analysis indicated that the primary tumor control correlated directly with the survival period. Some patients with a primary tumor which was easy to control developed lung metastasis more often. Liver metastasis was found more frequently in patients where the primary tumor was located in the lower portion of the esophagus. Patients with a tumor length of more than 10 cm had neck or mediastinal lymph node involvement more often; neck or mediastinal lymph node metastases were not always fatal immediately. Perforations into other organs were observed in 41.8% of the patients. Younger patients, patients with the tumor located in the upper portion of the esophagus, and patients with T4 tumor have a significantly higher risk of perforation. In such a patient, the total radiation dose should be reduced to less than 70 Gy. Nine patients (9.9%) had double cancers. (author)

Esophageal adenocarcinoma (EAC) is rapidly increasing in incidence in Western cultures. Barrett’s esophagus (BE) is the presumed precursor lesion for this cancer. Several other risk factors for this cancer have been described, including chronic heartburn, tobacco use, Caucasian race, and obesity. Despite these known associations, most patients with EAC present with symptoms of dysphagia from late-stage tumors—only a small minority of patients are identified in screening and surveillance programs. Diagnostic analysis of EAC usually commences with upper endoscopy, followed by cross-sectional imaging. Endoscopic ultrasound is useful to assess local extent of disease as well as the involvement regional lymph nodes. T1a EAC may be treated endoscopically; some patients with T1b disease might also benefit from endoscopic therapy. Locally advanced disease is generally managed with esophagectomy, often accompanied by neoadjuvant chemoradiotherapy or chemotherapy. The prognosis is based on tumor stage: patients with T1a tumors have an excellent prognoses, whereas few patients with advanced disease have longterm survival. PMID:25957861

Esophageal diverticula and cancer.

Esophageal diverticula are rare. The association of cancer and diverticula has been described. Some authors adopt a conservative non-surgical approach in selected patients with diverticula whereas others treat the symptoms by diverticulopexy or myotomy only, leaving the diverticulum in situ. However, the risk of malignant degeneration should be may be taken in account if the diverticulum is not resected. The correct evaluation of the possible risk factors for malignancy may help in the decision making process. We performed a literature review of esophageal diverticula and cancer. The incidence of cancer in a diverticulum is 0.3-7, 1.8, and 0.6% for pharyngoesophageal, midesophageal, and epiphrenic diverticula, respectively. Symptoms may mimic those of the diverticulum or underlying motor disorder. Progressive dysphagia, unintentional weight loss, the presence of blood in the regurgitated material, regurgitation of peaces of the tumor, odynophagia, melena, hemathemesis, and hemoptysis are key symptoms. Risk factors for malignancy are old age, male gender, long-standing history, and larger diverticula. A carcinoma may develop in treated diverticula, even after resection. Outcomes are usually quoted as dismal because of a delayed diagnosis but several cases of superficial carcinoma have been described. The treatment follows the same principals as the therapy for esophageal cancer; however, diverticulectomy is enough in cases of superficial carcinomas. Patients must be carefully evaluated before therapy and a long-term follow-up is advisable. © 2011 Copyright the Authors.

Woodward, Timothy A.; Wolfsen, Herbert C.

2000-05-01

In 1995, PDT was approved for palliative use in patients with esophageal cancer. We report our experience using PDT to treat esophageal cancer patients previously treated with combination chemotherapy and radiation therapy. In our series, nine patients referred for PDT with persistent esophageal cancer after chemo-radiation therapy. We found: (1) All patients were men with a mean age of 63 years and eight out of nine had adenocarcinoma with Barrett's esophagus; (2) All patients required endoscopic dilation after PDT; (3) At a mean follow up of 4 months, two T2N0 patients had no demonstrable tumor and all three T3N0 patients had greater than 50% tumor reduction (the partially responsive T3N0 patients will be offered repeat PDT); (4) Patients with metastatic disease (T3N1 or M1) had effective dysphagia palliation. Thus, PDT is safe and effective in ablating all or most tumor in patients with persistent esophageal cancer after chemotherapy and radiation therapy.

Esophageal cancers are highly malignant tumours with often a poor prognosis, except for minimal lesions treated with surgery. Radiation therapy, or combined radiation and chemotherapy is the most used therapeutic modality, alone or before oesophagectomy. The delineation of target volumes is now more accurate owing the possibility to use routinely the new imaging techniques (mainly PET). The aim of this work is to precise the radio-anatomical particularities, the pattern of spread of esophageal cancer and the principles of 3D conformal radiotherapy illustrated with a clinical case.

1996-01-01

Introduction: There is wide variation in the indications, techniques, treatment regimens and dosimetry being used to treat cancer of the esophagus and no guidelines exist for optimal therapy. Methods: The Clinical Research Committee of the ABS met to formulate consensus guidelines for brachytherapy in esophageal cancer. Results: Good candidates for brachytherapy include patients with unifocal disease, with thoracic tumor 10 cm primary regional lymph adenopathy or tumor located in the gastro-esophageal junction or cervical esophagus. Contraindications include tracheo-esophageal fistula or stenosis that cannot be by-passed. The esophageal or nasogastric tube inserted should have a diameter of 6-10 mm whenever possible. If 5FU-based chemotherapy and 50 Gy external beam (EBRT) are used, it is suggested that the low dose rate brachytherapy (LDR) dose be 20 Gy at 0.4-1 Gy/hr, prescribed at 1 cm from the source. If high dose rate (HDR) is used, the dose recommended is 10 Gy in 2 weekly fractions of 5 Gy each, given after EBRT. Chemotherapy is not usually given concurrently with brachytherapy, and when it is, the brachytherapy dose is reduced. The length of esophagus treated by brachytherapy includes the post-EBRT involved area and a 1-2 cm margin proximally and distally. Supportive care, given during EBRT includes an antifungal agent (e.g., diflucan) and carafate. Gradual dilatation of the esophagus is required post-treatment for esophageal strictures. Conclusion: Guidelines were developed for brachytherapy in esophageal cancer. As more clinical data becomes available, these guidelines will be updated by the ABS

Hypnotherapy for Esophageal Disorders.

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.

tumor de esôfago em nosso meio ainda é muito tardio, limitando o benefício que poderia advir dos métodos de ponta de paliação endoscópica.BACKGROUND: Esophageal cancer is one of the 10 most common cancers in Brazil. Diagnosis is usually late and mean survival ranges from 4 to 6 months, no matter the treatment. Relief of dysphagia and increase in life quality are the main targets of palliative therapy. AIM: To evaluate patients with advanced esophageal tumor submitted to various palliative treatment options. PATIENTS AND METHOD: We prospectively evaluated 38 patients with advanced esophageal cancer, with dysphagia and no chance of curative treatment, between September 2001 and June 2005. Patients were treated according to available resources, patient or referring physician's preference: 14 patients were treated with esophageal stent (9 self-expandable metallic, 4 plastic, 1 expandable plastic, 4 with palliative surgery, 8 gastrostomy (7 surgical and 1 endoscopic and 12 nasogastric tube. RESULTS: The mean dysphagia score 30 days after the procedure was improved in all groups except in the gastrostomy. Karnofsky score, reflecting quality of life, showed no improvement. The number of hospital admissions was not different among groups. Although the length of hospitalization was longer in the surgical group (42 days, it did not reach statistical significance. There was not statistically significant difference in the mean survival time among all patients. CONCLUSION: An ideal palliative treatment does not exist. The method must be individualized for each patient. Surgical treatment is the most expensive, once it requires longer periods in hospital. Unfortunately, the diagnosis of esophageal tumors is still delayed, limiting the benefits of top endoscopic palliation therapy.

In this study, the effectiveness of sucralfate against stricture formation in experimental corrosive esophageal burn is reported. Sixty-four Swiss albino adult male rats were divided into three groups, group A (control; n, 7), group B (esophageal burn induced but not treated; n, 25), and group C (esophageal burn induced and treated with sucralfate, n, 32). Groups B and C were further subdivided into subgroups for evaluation on days 2, 7, and 28. A standard esophageal burn was performed by the method of Gehanno, using 50% NaOH. Oral sucralfate treatment was given to group C at a dosage of 50 mg/100 g twice daily. The rats were then killed after 2, 7, or 28 days. Levels of tissue hydroxyproline were measured in excised abdominal esophageal segments, and a histopathological evaluation was performed with hematoxylin-eosin and Masson's trichrome staining. The tissue hydroxyproline levels were significantly lower in group C than in group B (P = 0.017). There was a significant difference in the stenosis index between groups B and C (P = 0.016). When compared with group B, the collagen deposition in the submucosa and tunica muscularis was significantly lower in group C (P = 0.02). Sucralfate has an inhibitory effect on stricture formation in experimental corrosive burns and can be used in the treatment of corrosive esophageal burns to enhance mucosal healing and suppress stricture formation.

Severe postoperative strictures in two children and an infant and mild postoperative stricture in a child were treated with balloon catheter. A child with post-fundoplication stricture showed symptomatic improvement. Anastomotic strictures after esophageal atresia repair in an infant and a child were successfully dilated with improved luminal diameter and symptoms. In a child with mild postoperative stricture, balloon dilatation was performed to prevent stricture of the anastomotic site. Radiological esophageal dilatation using balloon catheters is a safe effective method for dilating symptomatic esophageal strictures which obviates surgery and allows subsequent standard bougienage.

Novel device to sample the esophageal microbiome--the esophageal string test.

Directory of Open Access Journals (Sweden)

Sophie A Fillon

Full Text Available A growing number of studies implicate the microbiome in the pathogenesis of intestinal inflammation. Previous work has shown that adults with esophagitis related to gastroesophageal reflux disease have altered esophageal microbiota compared to those who do not have esophagitis. In these studies, sampling of the esophageal microbiome was accomplished by isolating DNA from esophageal biopsies obtained at the time of upper endoscopy. The aim of the current study was to identify the esophageal microbiome in pediatric individuals with normal esophageal mucosa using a minimally invasive, capsule-based string technology, the Enterotest™. We used the proximal segment of the Enterotest string to sample the esophagus, and term this the "Esophageal String Test" (EST. We hypothesized that the less invasive EST would capture mucosal adherent bacteria present in the esophagus in a similar fashion as mucosal biopsy. EST samples and mucosal biopsies were collected from children with no esophageal inflammation (n = 15 and their microbiome composition determined by 16S rRNA gene sequencing. Microbiota from esophageal biopsies and ESTs produced nearly identical profiles of bacterial genera and were different from the bacterial contents of samples collected from the nasal and oral cavity. We conclude that the minimally invasive EST can serve as a useful device for study of the esophageal microbiome.

Full Text Available ABSTRACT Background Esophageal cancer is one of the leading causes of mortality among the neoplasms that affect the gastrointestinal tract. There are several factors that contribute for development of an epidemiological esophageal cancer profile in a population. Objective This study aims to describe both clinically and epidemiologically the population of patients with diagnosis of esophageal cancer treated in a quaternary attention institute for cancer from January, 2009 to December, 2011, in Sao Paulo, Brazil. Methods The charts of all patients diagnosed with esophageal cancer from January, 2009, to December, 2011, in a Sao Paulo (Brazil quaternary oncology institute were retrospectively reviewed. Results Squamous cell cancer made up to 80% of the cases of esophageal cancer. Average age at diagnosis was 60.66 years old for esophageal adenocarcinoma and 62 for squamous cell cancer, average time from the beginning of symptoms to the diagnosis was 3.52 months for esophageal adenocarcinoma and 4.2 months for squamous cell cancer. Average time for initiating treatment when esophageal cancer is diagnosed was 4 months for esophageal adenocarcinoma and 4.42 months for squamous cell cancer. There was a clear association between squamous cell cancer and head and neck cancers, as well as certain habits, such as smoking and alcoholism, while adenocarcinoma cancer showed more association with gastric cancer and gastroesophageal reflux disease. Tumoral bleeding and pneumonia were the main causes of death. No difference in survival rate was noted between the two groups. Conclusion Adenocarcinoma and squamous cell carcinoma are different diseases, but both are diagnosed in advanced stages in Brazil, compromising the patients' possibilities of cure.

Eosinophilic Esophagitis Is an Underlying Cause for Gastrointestinal Concerns in Children

Kunsong Lee

2018-05-01

Full Text Available Eosinophilic esophagitis (EoE is a chronic immune antigen-mediated disorder characterized by symptoms of esophageal dysfunction in combination with dense esophageal eosinophilia. The clinical presentation of EoE can vary depending on children's age and their ability to report symptoms, therefore a high index of suspicion for EoE is required because children and teenagers may develop coping strategies around eating. The development of symptoms measurement tools in EoE assists in not only assessing symptoms, but also coping strategies children may have developed. While the diagnosis of EoE requires endoscopic evaluation with histologic assessment of esophageal mucosal biopsy samples, several emerging methods to assess and survey the esophageal mucosa have been developed. Advances in the field to better understand the natural history, clinical and molecular features of phenotypes in EoE will be important in considering novel therapeutic options and assessing outcomes.

2014-08-01

Stent migration occurs in 10-40% of patients who undergo placement of esophageal stents, with higher migration rates seen in those treated for benign esophageal disorders. This remains a major drawback of esophageal stent therapy. In this paper, we propose a new surface modification method to increase the adhesion between self-expandable metallic stents (SEMS) and tissue while preserving their removability. Taking advantage of the well-known affinity between epoxide and amine terminated silane coupling agents with amine and carboxyl groups that are abundant in proteins and related molecules in the human body; we modified the surfaces of silicone coated esophageal SEMS with these adhesive self-assembled monolayers (SAMs). We utilized vapor phase silanization to modify the surfaces of different substrates including PDMS strips and SEMS, and measured the force required to slide these substrates on a tissue piece. Our results suggest that surface modification of esophageal SEMS via covalent attachment of protein-binding coupling agents improves adhesion to tissue and could offer a solution to reduce SEMS migration while preserving their removability.

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

Sixty patients entered a double-blind clinical trial comparing the effect of 1 g of sucralfate granulate given four times daily and cimetidine, 400 mg twice daily. Twenty-six patients treated with sucralfate and 26 treated with cimetidine were examined with short-term pH monitoring before and after 12 weeks of treatment. Thirty patients, 19 treated with cimetidine and 11 treated with sucralfate, had esophageal motility studied by a radionuclide test before and after 12 weeks of treatment. The efficacy of the treatments was judged by symptoms and endoscopic response after 4, 8, and 12 weeks of treatment. The endpoint healing rate was approximately 60% in both groups and symptoms were relieved in half of the patients in both groups (difference not significant). The effect of the treatments on pH and number of spikes reflected the different pharmacodynamic profiles of the drugs, whereas the mean transit time (MTT) was not changed by the treatments. The residual activity after radionuclide transit in the sitting position was significantly increased after treatment with cimetidine. The data support the hypothesis that primary dysmotility might be involved in the pathogenesis of reflux esophagitis in about 33% of the patients. Possibilities for a combination therapy with sucralfate and cimetidine are stressed

Huff, Janice; Patel, Zarana; Grugan, Katharine; Rustgi, Anil; Cucinotta, Francis A.

Esophageal cancer is the 6th leading cause of cancer death worldwide and is associated with a variety of risk factors including tobacco use, heavy alcohol consumption, human papilloma virus infection, and certain dietary factors such as trace mineral and vitamin deficiencies. A connection with ionizing radiation exposure is revealed by the high excess relative risk for esophageal squamous cell carcinoma observed in the survivors of the atomic bomb detonations in Japan. Esophageal carcinomas are also seen as secondary malignancies in patients who received radiotherapy for breast and thoracic cancers; additionally, patients with head/neck and oral squamous cell cancers are at increased risk for metachronous esophageal squamous cell cancers. This malignancy is rapidly fatal, mainly because it remains asymptomatic until late, advanced stages when the disease is rarely responsive to treatment. In normal epithelium, the stromal microenvironment is essential for the maintenance and modulation of cell growth and differentiation. Cross talk between the epithelial and stromal compartments can influence many aspects of malignant progression, including tumor cell proliferation, migration, invasion and recruitment of new blood vessels. To test the hypothesis that radiation exposure plays a role in esophageal carcinogenesis via non-targeted mechanisms involving stromal-epithelial cell communication, we are studying radiation effects on hTERT-immortalized human esophageal epithelial cells and genetic variants grown in co-culture with human esophageal stromal fibrob-lasts (Okawa et al., Genes Dev. 2007. 21: 2788-2803). We examined how irradiation of stromal fibroblasts affected epithelial migration and invasion, behaviors associated with cancer promotion and progression. These assays were conducted in modified Boyden chambers using conditioned media from irradiated fibroblasts. Our results using low LET gamma radiation showed a dose-dependent increase in migration of epithelial

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.

Herpetic esophagitis

1981-01-01

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

Full Text Available Endoscopic variceal sclerotherapy and ligation are standard treatment modalities used for the management of esophageal varices. Reportedly, sclerotherapy and ligation are associated with complications such as hematuria, pulmonary thrombus formation, pleural effusion, renal dysfunction, and esophageal stenosis. However, hemothorax following sclerotherapy and ligation has not yet been reported. We treated a patient who presented with liver cirrhosis and polycythemia vera and later developed hemothorax following the above-mentioned procedures. An 86-year-old man diagnosed with liver cirrhosis due to chronic hepatitis type B and alcohol abuse underwent variceal sclerotherapy using ethanolamine oleate to treat his esophageal varices. Oozing from the esophageal varices continued even after the sclerotherapy procedure; therefore, we performed endoscopic variceal ligation. The patient developed left-sided hemothorax within 24 h after treatment of his varices, and an emergency thoracotomy was performed. A pulmonary ligament of the left lung was bulging and ripping because of mediastinal hematoma, and oozing was noted. Cessation of bleeding was noted after the laceration of the left pulmonary ligament had been sutured. Ours is the first case of hemothorax reported in a patient following an uncomplicated procedure of sclerotherapy and ligation.

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.

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.

Gastro-esophageal reflux time parameters and esophagitis in children

International Nuclear Information System (INIS)

Baulieu, F.; Baulieu, J.; Maurage, C.; Casset, D.; Itti, R.

1985-01-01

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-99m 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

Background: Previous studies from South Africa have established that fractionated high-dose-rate (HDR) brachytherapy gives the best results in terms of palliation and survival in advanced esophageal cancer. A multicenter, prospective randomized study was therefore conducted under the auspices of the International Atomic Energy Agency to evaluate two HDR regimens. Methods and Materials: Surgically inoperable patients with histologically proven squamous cell cancer of the esophagus, tumor >5 cm in length on barium swallow and/or endoscopy, Karnofsky performance score >50, age 17-70 years, primary disease in the thoracic esophagus, no prior malignancy within the past 5 years, and any N or M status were included in the study. Exclusion criteria included cervical esophagus location, tumor extending 0.05). The overall survival was 7.9 months for the whole group (Group A, 9.1 months; Group B, 6.9 months; p>0.05). On univariate analysis, the presenting weight (p=0.0083), gender (p=0.0038), race (p=0.0105), the presenting dysphagia score (p=0.0083), the treatment center (p=0.0029), and tumor grade (p=0.0029) had an impact on the dysphagia-free survival, and gender (p=0.0011) and performance score (p=0.0060) had an impact on dysphagia-free survival on multivariate analysis. Only age had an impact on overall survival on both univariate (p=0.0430) and multivariate (p=0.0331) analysis. The incidence of strictures (Group A, n=12; Group B, n=13; p>0.05) and fistulas (Group A, n=11; Group B, n=12; p>0.05) was similar in both groups. Conclusion: Fractionated HDR brachytherapy alone is an effective method of palliating advanced esophageal cancers, surpassing the results of any other modality of treatment presently available. Dose fractions of 6 Gy x 3 and 8 Gy x 2 give similar results for dysphagia-free survival, overall survival, strictures, and fistulas and are equally effective in palliation of advanced esophageal cancer

The Role of Esophageal Hypersensitivity in Functional Heartburn.

Science.gov (United States)

Kondo, Takashi; Miwa, Hiroto

2017-08-01

Functional heartburn (FH) is defined as a functional esophageal disorder characterized by symptoms of chronic heartburn with no apparent correlation to acid or nonacid reflux. In addition, its symptoms persist despite the lack of organic abnormalities or inflammation, esophageal motility disorders, or metabolic disorders. Although conditions presenting with esophageal symptoms without endoscopic abnormalities were previously categorized as nonerosive reflux disease, such conditions are now classified into 3 categories under Rome IV criteria: nonerosive reflux disease, reflux hypersensitivity, and FH. Although many aspects of FH remain unclear, its onset mechanism is considered to be strongly associated with peripheral or central sensitization, given the fact that its symptoms seem to be unrelated to gastroesophageal reflux. In addition, the cause of such hypersensitivity is an interesting topic in itself, and psychological factors, such as stress followed by increasing esophageal permeability are gaining attention as factors that can potentially influence this condition. There is a great unmet clinical need for therapeutic drugs that can be used to treat FH, and the development of novel drugs, diagnostic tests and biomarkers is eagerly awaited.

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

Esophageal hypomotility and spastic motor disorders: current diagnosis and treatment.

Science.gov (United States)

Valdovinos, Miguel A; Zavala-Solares, Monica R; Coss-Adame, Enrique

2014-11-01

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

Epidermal growth factor receptor (EGFR) has been reported to be overexpressed and amplified in a high percentage of patients with esophageal squamous cell carcinoma (ESCC). The activity of icotinib, an EGFR tyrosine kinase inhibitor, was assessed in previously treated ESCC with EGFR overexpression or amplification. For this phase 2, single-arm, multicenter trial undertaken at six hospitals in China, we included Chinese patients with previously treated, histologically confirmed advanced ESCC and EGFR overexpression (immunohistochemical staining sore of 3+) or amplification (positive fluorescence in situ hybridization result). These patients received oral icotinib (250 mg, three times daily).The primary end point was the proportion of patients with objective responses as assessed by an independent radiology review committee. Between December 5, 2013, and May 28, 2015, a total of 281 patients were screened. Fifty-four eligible patients were enrolled. Nine responses were observed, including one complete response and eight partial responses, and 16 patients had stable disease, resulting in a 16.7% objective response rate (95% confidence interval [CI]: 6.7-26.6) and 46.3% disease control rate (95% CI: 33.0-59.6). The median progression-free survival and overall survival times were 52 (95% CI: 40-95) days and 153 (95% CI: 139-218) days, respectively. A total of 43 patients experienced at least one adverse event, but most were only grade 1 to 2 in severity. The most frequent was rash (48.1%), followed by diarrhea (22.2%). Icotinib showed favorable activity in patients with advanced, previously treated ESCC with EGFR overexpression or amplification. These findings suggest further research into EGFR overexpression or amplification for selecting responsive patients. Copyright © 2016 International Association for the Study of Lung Cancer.

Conclusions: 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 patients with EoE.

This retrospective study was done to examine whether the heterogeneity in primary tumour F-18-fluorodeoxyglucose ({sup 18}F-FDG) distribution can predict tumour response and prognosis of patients with esophageal cancer treated by chemoradiotherapy (CRT). The enrolled 52 patients with esophageal cancer underwent {sup 18}F-FDG-PET/CT studies before CRT. SUVmax, SUVmean, metabolic tumour volume (MTV, SUV ≥ 2.5), total lesion glycolysis (TLG) and six heterogeneity parameters assessed by texture analysis were obtained. Patients were classified as responders or non-responders according to Response Evaluation Criteria in Solid Tumors. Progression-free survival (PFS) and overall survival (OS) were calculated by the Kaplan-Meier method. Prognostic significance was assessed by Cox proportional hazards analysis. Thirty four non-responders showed significantly higher MTV (p = 0.006), TLG (p = 0.007), intensity variability (IV; p = 0.003) and size-zone variability (SZV; p = 0.004) than 18 responders. The positive and negative predictive values for non-responders were 77 % and 69 % in MTV, 76 % and 100 % in TLG, 78 % and 67 % in IV and 78 % and 82 % in SZV, respectively. Although PFS and OS were significantly shorter in patients with high MTV (PFS, p = 0.018; OS, p = 0.014), TLG (PFS, p = 0.009; OS, p = 0.025), IV (PFS, p = 0.013; OS, p = 0.007) and SZV (PFS, p = 0.010; OS, p = 0.007) at univariate analysis, none of them was an independent factor, while lymph node status, stage and tumour response status were independent factors at multivariate analysis. Texture features IV and SZV, and volumetric parameters MTV and TLG can predict tumour response, but all of them have limited value in prediction of prognosis of patients with esophageal cancer treated by CRT.

Receptor interactive protein kinase 3 promotes Cisplatin-triggered necrosis in apoptosis-resistant esophageal squamous cell carcinoma cells.

Directory of Open Access Journals (Sweden)

Yang Xu

Full Text Available Cisplatin-based chemotherapy is currently the standard treatment for locally advanced esophageal cancer. Cisplatin has been shown to induce both apoptosis and necrosis in cancer cells, but the mechanism by which programmed necrosis is induced remains unknown. In this study, we provide evidence that cisplatin induces necrotic cell death in apoptosis-resistant esophageal cancer cells. This cell death is dependent on RIPK3 and on necrosome formation via autocrine production of TNFα. More importantly, we demonstrate that RIPK3 is necessary for cisplatin-induced killing of esophageal cancer cells because inhibition of RIPK1 activity by necrostatin or knockdown of RIPK3 significantly attenuates necrosis and leads to cisplatin resistance. Moreover, microarray analysis confirmed an anti-apoptotic molecular expression pattern in esophageal cancer cells in response to cisplatin. Taken together, our data indicate that RIPK3 and autocrine production of TNFα contribute to cisplatin sensitivity by initiating necrosis when the apoptotic pathway is suppressed or absent in esophageal cancer cells. These data provide new insight into the molecular mechanisms underlying cisplatin-induced necrosis and suggest that RIPK3 is a potential marker for predicting cisplatin sensitivity in apoptosis-resistant and advanced esophageal cancer.

The Role of Esophageal Hypersensitivity in Functional Esophageal Disorders.

Farmer, Adam D; Ruffle, James K; Aziz, Qasim

2017-02-01

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.

Purpose: To evaluate the effect of radiation dose escalation on overall survival (OS) for patients with nonmetastatic esophageal cancer treated with concurrent radiation and chemotherapy. Methods and Materials: Patients diagnosed with stage I to III esophageal cancer treated from 2004 to 2012 were identified from the National Cancer Data Base. Patients who received concurrent radiation and chemotherapy with radiation doses of ≥50 Gy and did not undergo surgery were included. OS was compared using Cox proportional hazards regression and propensity score matching. Results: A total of 6854 patients were included; 3821 (55.7%) received 50 to 50.4 Gy and 3033 (44.3%) received doses >50.4 Gy. Univariate analysis revealed no significant difference in OS between patients receiving 50 to 50.4 Gy and those receiving >50.4 Gy (P=.53). The dose analysis, binned as 50 to 50.4, 51 to 54, 55 to 60, and >60 Gy, revealed no appreciable difference in OS within any group compared with 50 to 50.4 Gy.

Purpose: To evaluate the effect of radiation dose escalation on overall survival (OS) for patients with nonmetastatic esophageal cancer treated with concurrent radiation and chemotherapy. Methods and Materials: Patients diagnosed with stage I to III esophageal cancer treated from 2004 to 2012 were identified from the National Cancer Data Base. Patients who received concurrent radiation and chemotherapy with radiation doses of ≥50 Gy and did not undergo surgery were included. OS was compared using Cox proportional hazards regression and propensity score matching. Results: A total of 6854 patients were included; 3821 (55.7%) received 50 to 50.4 Gy and 3033 (44.3%) received doses >50.4 Gy. Univariate analysis revealed no significant difference in OS between patients receiving 50 to 50.4 Gy and those receiving >50.4 Gy (P=.53). The dose analysis, binned as 50 to 50.4, 51 to 54, 55 to 60, and >60 Gy, revealed no appreciable difference in OS within any group compared with 50 to 50.4 Gy. Subgroup analyses investigating the effect of dose escalation by histologic type and in the setting of intensity modulated radiation therapy also failed to reveal a benefit. Propensity score matching confirmed the absence of a statistically significant difference in OS among the dose levels. The factors associated with improved OS on multivariable analysis included female sex, lower Charlson-Deyo comorbidity score, private insurance, cervical/upper esophagus location, squamous cell histologic type, lower T stage, and node-negative status (P<.01 for all analyses). Conclusions: In this large national cohort, dose escalation >50.4 Gy did not result in improved OS among patients with stage I to III esophageal cancer treated with definitive concurrent radiation and chemotherapy. These data suggest that despite advanced contemporary treatment techniques, OS for patients with esophageal cancer remains unaltered by escalation of radiation dose >50.4 Gy, consistent with the results of

Esophageal cancer is located in the 8th position of the incidence of malignant tumors and the 6th most common cause of cancer-related mortality in the world, while China has the highest incidence and mortality of esophageal cancer. Esophageal squamous cell carcinoma (ESCC), the predominant histologic type of esophageal cancer in China, accounts for about 90%. Despite recent improvement of surgical techniques and philosophy, however, the prognosis of ESCC patients treated with surgery is still poor, and 5-year survival remains unsatisfactorily low. So far, the pathogenesis of esophageal squamous cell carcinoma is still unclear, and effective prevention is also out of the question. To find the main factors affecting the prognosis of esophageal squamous cell carcinoma, and to improve the survival of patients, are the main directions of all scholars. Postoperative pathology of esophageal squamous cell carcinoma is considered to be one of the most important predictors of prognosis. Currently, the evaluation of postoperative esophageal prognosis mainly depends on TNM staging, but some criteria of its specific content and staging remains controversial. In this paper recent domestic and foreign related researches and clinical trials reports are collected, and the postoperative pathological features affecting esophageal squamous cell carcinoma prognosis were reviewed.

Tracheobronchial stenosis in patients with esophageal cancer can be life threatening. Few reports have discussed use of expandable metallic stents for central airway stenoses in patients with esophageal cancer. Twelve patients with esophageal cancer underwent placement of expandable metallic stents for respiratory distress caused by tracheobronchial stricture. Single or double metallic stents were placed in the stenotic airways under fluoroscopic guidance. Improvement in respiratory symptoms and clinical outcome were assessed. Most stenoses were located in the trachea or the left main bronchus. From one to four expandable metallic stents were placed in each stricture site, with immediate relief of respiratory symptoms in 8 patients. One patient with tracheomalacia in alive 3 years after stent placement and another is alive 6 months after stent insertion. The other 10 patients lived from 10 to 70 days (mean; survival, 35 days) after stent placement. Death was due to progression of disease. Although metallic stents are useful for relieving respiratory distress in patients with advanced esophageal cancer, additional therapies should be considered.

Full Text Available Background: High-resolution manometer (HRM of the esophagus has become the main diagnostic test in the evaluation of esophageal motility disorders. 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 first step of the Chicago classification described abnormal esophagogastric junction deglutitive relaxation. The latest classification system, proposed by Pandolfino et al, includes contraction patterns and peristalsis integrity based on integrated relaxation pressure 4 (IRP4. It can be discriminating the achalasia from non-achalasia esophageal motility disorders. The aim of this study was to assessment of clinical findings in non-achalasia esophageal motility disorders based on the most recent Chicago classification. Methods: We conducted a prospective cross-sectional study of 963 patients that had been referred to manometry department of Gastrointestinal and Liver Research Center, Firozgar Hospital, Tehran, Iran, from April, 2012 to April, 2015. They had upper GI disorder (Dysphasia, non-cardiac chest pain, regurgitation, heartburn, vomiting and asthma and weight loss. Data were collected from clinical examinations as well as patient questionnaires. Manometry, water-perfused, was done for all patients. Manometry criteria of the patients who had integrated relaxation pressure 4 (IRP4 ≤ 15 mmHg were studied. Results: Our finding showed that the non-achalasia esophageal motility disorders (58% was more common than the achalasia (18.2%. Heartburn (68.5%, regurgitation (65.4% and non-cardiac chest pain (60.6% were the most common clinical symptoms. Although, vomiting (91.7% and weight loss (63% were the most common symptoms in referring patients but did not discriminate this disorders from each other’s. Borderline motor function (67.2% was the most common, absent peristalsis (97% and the hyper

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.

Full Text Available Introduction: Lung cancer patients receiving radiotherapy present with acute esophagitis and chronic fibrosis, as a result of radiation injury to esophageal tissues. We have shown that soy isoflavones alleviate pneumonitis and fibrosis caused by radiation toxicity to normal lung. The effect of soy isoflavones on esophagitis histopathological changes induced by radiation was investigated. Methods: C57BL/6 mice were treated with 10 Gy or 25 Gy single thoracic irradiation and soy isoflavones for up to 16 weeks. Damage to esophageal tissues was assessed by H&E, Masson’s Trichrome and Ki-67 staining at 1, 4, 10, 16 weeks after radiation. The effects on smooth muscle cells and leukocyte infiltration were determined by immunohistochemistry using anti-αSMA and anti-CD45 respectively. Results: Radiation caused thickening of esophageal tissue layers that was significantly reduced by soy isoflavones. Major radiation alterations included hypertrophy of basal cells in mucosal epithelium and damage to smooth muscle cells in muscularis mucosae as well as disruption of collagen fibers in lamina propria connective tissue with leukocyte infiltration. These effects were observed as early as one week after radiation and were more pronounced with a higher dose of 25 Gy. Soy isoflavones limited the extent of tissue damage induced by radiation both at 10 and 25 Gy.Conclusions: Soy isoflavones have a radioprotective effect on the esophagus, mitigating the early and late effects of radiation injury in several esophagus tissue layers. Soy could be administered with radiotherapy to decrease the incidence and severity of esophagitis in lung cancer patients receiving thoracic radiation therapy.

Purpose: To analyze retrospectively the long-term results of external beam radiotherapy (RT) with or without intraluminal brachytherapy (ILBT) for patients with Stage I esophageal cancer. Methods and Materials: A total of 34 patients with esophageal squamous cell carcinoma, clinically diagnosed as having Stage I disease, were treated with definitive RT, with or without ILBT. The median age was 69 years. Seven patients were treated with external beam RT alone (median, 64 Gy), and 27 were treated with external beam RT (median, 52 Gy) plus ILBT (8-12 Gy in two to three fractions). Results: The 5-year overall survival, local relapse-free survival, and cause-specific survival rate was 58.9%, 68.4%, and 80.0%, respectively, with a median follow-up of 61 months. Of 9 patients with local recurrence after initial therapy, 7 were successfully treated, and the 5-year cumulative rate of esophagectomy was 19.6%. The 2-year local relapse-free rate for patients with and without ILBT was 79.1% and 53.6%, respectively. Conclusion: Although local recurrence was frequent within 2 years, the disease-specific survival rate was high owing to effective salvage therapy. Definitive RT is a reasonable treatment option for highly comorbid and elderly patients with Stage I esophageal cancer. The role of ILBT needs to be clarified

Esophageal stricture formation after extensive endoscopic resection remains a major limitation of endoscopic therapy for early esophageal neoplasia. This study assessed a recently developed self-assembling peptide (SAP) matrix as a wound dressing after endoscopic resection for the prevention of esophageal stricture. Ten pigs were randomly assigned to the SAP or the control group after undergoing a 5-cm-long circumferential endoscopic submucosal dissection of the lower esophagus. Esophageal diameter on endoscopy and esophagogram, weight variation, and histological measurements of fibrosis, granulation tissue, and neoepithelium were assessed in each animal. The rate of esophageal stricture at day 14 was 40% in the SAP-treated group versus 100% in the control group (P = 0.2). Median interquartile range (IQR) esophageal diameter at day 14 was 8 mm (2.5-9) in the SAP-treated group versus 4 mm (3-4) in the control group (P = 0.13). The median (IQR) stricture indexes on esophagograms at day 14 were 0.32 (0.14-0.48) and 0.26 (0.14-0.33) in the SAP-treated and control groups, respectively (P = 0.42). Median (IQR) weight variation during the study was +0.2 (-7.4; +1.8) and -3.8 (-5.4; +0.6) in the SAP-treated and control groups, respectively (P = 0.9). Fibrosis, granulation tissue, and neoepithelium were not significantly different between the groups. The application of SAP matrix on esophageal wounds after a circumferential endoscopic submucosal dissection delayed the onset of esophageal stricture in a porcine model. © International Society for Diseases of the Esophagus 2017.

Esophageal cancer is a devastating disease with rapidly increasing incidence in Western countries. Dysphagia is the most common complication, causing severe malnutrition and reduced quality of life. A 69-year-old male with persistent esophageal cancer after radiation therapy was subjected to palliative by-pass surgery using a laparoscopic approach. Due to the advanced stage at diagnosis, palliative treatment was a more realistic option. Dysphagia is a most distressing symptom of this disease, causing malnutrition and reducing quality of life. The goal of palliation is to improve swallowing. The most common methods applied are endoscopic stenting, radiation therapy (external or brachytherapy), chemotherapy, yttrium-aluminum-garnet laser rechanneling or endoscopic dilatation. Palliative surgery is rarely proposed due to morbidity and complications. This paper demonstrates an update in the technique proposed by Postlethwait in 1979 for palliation of esophageal cancer.

BACKGROUND Patients with esophageal achalasia are considered to be a high-risk group for esophageal carcinoma, and it has been reported that this cancer often arises at a long interval after surgery for achalasia. However, it is unclear whether esophageal carcinoma is frequent when achalasia has been treated successfully and the patient is without dysphagia. In this study, we reviewed patients with esophageal carcinoma who were detected by regular follow-up after surgical treatment of achalasia.   CASE REPORT Esophageal cancer was detected by periodic upper GI endoscopy in 6 patients. Most of them had early cancers that were treated by endoscopic resection. All 6 patients had undergone surgery for achalasia and the outcome had been rated as excellent or good. Annual follow-up endoscopy was done and the average duration of follow-up until cancer was seen after surgery was 14.3 years (range: 5 to 40 years). Five patients had early cancer. Four cases had multiple lesions.   CONCLUSIONS In conclusion, surgery for achalasia usually improves passage symptoms, but esophageal cancer still arises in some cases and the number of tumors occurring many years later is not negligible. Accordingly, long-term endoscopic follow-up is needed for detection of malignancy at an early stage.

For the better understanding of esophageal motility, the muscle texture and the distribution of skeletal and smooth muscle fibers in the esophagus are of crucial importance. Esophageal physiology will be shortly mentioned as far as necessary for a comprehensive understanding of peristaltic disturbances. Besides the pure depiction of morphologic criteria, a complete esophageal study has to include an analysis of the motility. New diagnostic tools with reduced radiation for dynamic imaging (digital fluoroscopy, videofluoroscopy) at 4-30 frames/s are available. Radiomanometry is a combination of a functional pressure measurement and a simultaneous dynamic morphologic analysis. Esophageal motility disorders are subdivided by radiologic and manometric criteria into primary, secondary, and nonclassifiable forms. Primary motility disorders of the esophagus are achalasia, diffuse esophageal spasm, nutcracker esophagus, and the hypertonic lower esophageal sphincter. The secondary motility disorders include pseudoachalasia, reflux-associated motility disorders, functionally caused impactions, Boerhaave's syndrome, Chagas' disease, scleroderma, and presbyesophagus. The nonclassificable motility disorders (NEMD) are a very heterogeneous collective. (orig.) [de

Full Text Available Spontaneous esophageal perforation is relatively uncommon, but carries a high mortality rate if diagnosis or treatment is delayed. We report the case of a 68-year-old man with spontaneous esophageal perforation who was successfully treated over 96 h after onset by thoracic drainage and jejunostomy for enteral nutrition. He vomited after drinking alcohol, soon followed by epigastralgia. Heart failure was suspected on admission to another hospital. Spontaneous esophageal perforation was diagnosed 48 h after admission. Chest tube drainage was performed, but his general condition deteriorated and he was transferred to our hospital. Emergent surgery was performed and esophageal perforation combined with pyothorax and mediastinitis was identified on the left side of the lower esophagus. The left thoracic cavity was rinsed and thoracic drainage was performed. Feeding jejunostomy was performed for postoperative enteral nutrition. Effective drainage and sufficient nutrition management appear extremely valuable in treating spontaneous esophageal perforation.

Multicenter retrospective case series and review of the literature. To determine the rate of esophageal perforations following anterior cervical spine surgery. 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. 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. 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.

Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg 2  cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.

Full Text Available Yingming Zhu,* Minghuan Li,* Li Kong, Jinming Yu Department of Radiation Oncology, Shandong Cancer Hospital and Institute, Shandong University, Jinan, Shandong, People’s Republic of China *These authors contributed equally to this work Abstract: Esophageal cancer is the sixth leading cause of cancer death worldwide, and patients who are treated with surgery alone, without neoadjuvant therapies, experience frequent relapses. Whether postoperative therapies could reduce the recurrence or improve overall survival is still controversial for these patients. The purpose of our review is to figure out the value of postoperative adjuvant therapy and address the disputes about target volume delineation according to published data. Based on the evidence of increased morbidity and disadvantages on patient survival caused by postoperative chemotherapy or radiotherapy (RT alone provided by studies in the early 1990s, the use of postoperative adjuvant therapies in cases of esophageal squamous cell carcinoma has diminished substantially and has been replaced gradually by neoadjuvant chemoradiation. With advances in surgery and RT, accumulating evidence has recently rekindled interest in the delivery of postoperative RT or chemoradiotherapy in patients with stage T3/T4 or N1 (lymph node positive carcinomas after radical surgery. However, due to complications with the standard radiation field, a nonconforming modified field has been adopted in most studies. Therefore, we analyze different field applications and provide suggestions on the optimization of the radiation field based on the major sites of relapse and the surgical non-clearance area. For upper and middle thoracic esophageal carcinomas, the bilateral supraclavicular and superior mediastinal areas remain common sites of recurrence and should be encompassed within the clinical target volume. In contrast, a consensus has yet to be reached regarding lower thoracic esophageal carcinomas; the �

Full Text Available The aim of this study was to evaluate the complications and final function outcome of wrapping nonvascularized omentum graft around the suture line of esophageal anastomosis. Twelve adult local breed dogs were used in this study. The animals were divided into two equal groups (control and treated, all animal induced into general anesthesia by injection of atropen sulphate in a dose 0.04 mg/kg B.W, intramuscularly then after 15 minute given mixture of ketamine hydrochloride and xylazine hydrochloride in doses 15 mg/kg and 5 mg/kg B.W intramuscularly respectively. An oblique resection of about 1cm of the esophageal length and anastomosis by double layer of simple interrupted pattern by 2.0 cat gut suture (control group, same procedure was done in treated group except the wrapping the anastomosis site with patch of omentum tissue after lapratomy operation in the left flank region procedure. The clinical signs of treated animal revealed signs of dysphagia and regurgitation in treated group while this signs disappear in the control group. Radiological and histopathological examination of the anastomosis site performed at 15 and 30 days post operation. Radiological study recorded high degree of stenosis in the anastomosis site in treated group at 15 and 30 days post operation in compared with animals in control group that record mean degree of stenosis in treated group at 15 day (57.61±0.2 and at 30 day (55.78±0.2 while it recorded in control group at 15 day (39.34±1.04 and at 30 day (36.0.6 ±0.9, histopathological results recorded enhanced healing of anastomosis site in treated animals more than control animals. In conclusion we found that non vascularized omental graft prevent leak when used around the anastomosis line in esophageal and enhanced healing of anastomosis line but it increase the stenosis, fibrosis and adhesion of anastomosis site with surrounding muscle and this interferes with the swallowing as well as dysphagia and regurgitation

Smoking is a well-known risk factor for esophageal cancer. However, there are few reports that directly evaluate smoking as a prognostic factor for esophageal cancer. Moreover, scarce evidence is available on whether smoking interacts with major treatment modalities of esophageal cancer. In this study we retrospectively analyzed 364 patients with esophageal squamous cell cancer who were treated between 2001 and 2005 at our institution. Background characteristics, including smoking history, were analyzed as potential prognostic factors. Of the 363 patients, 76 patients (20.9%) were non-smokers or light smokers (non-heavy), whereas 287 patients (79.1%) were heavy smokers. The 5-year survival rate for non-heavy smokers and heavy smokers was 61.8% (95% confidence interval [CI]: 49.1-72.2) vs 44.6% (95% CI: 38.2-50.9), respectively. In a multivariate Cox model (adjusted for age, gender, performance status, alcohol consumption, histology, tumor length, International Union Against Cancer [UICC] stage, and treatment), the hazard ratio for heavy smokers in comparison with non-heavy smokers was 1.73 (95% CI: 1.12-2.68; P=0.013). When we stratified by treatment method, heavy smoking was significantly associated with poor survival only in patients treated by chemoradiotherapy (hazard ratio, 2.43; 95% CI: 1.38-4.27; P=0.002). More importantly, a statistically significant interaction between heavy smoking history and treatment modality was observed (P=0.041). Our results indicated that smoking history is strongly associated with poor prognosis in patients with esophageal cancer, especially those treated by chemoradiotherapy. Further investigation is warranted to explain this different prognosis. (author)

Esophageal cancer is one of the major health concerns in Southeast Asian countries, including Thailand. However, only a limited number of studies have been reported from this region. This study was designed to evaluate the prevalence, clinical characteristics and survival rate of esophageal cancer in Thailand. Clinical information, histological features and endoscopic findings were collected from a tertiary care center in central region of Thailand between September 2011- November 2014 and reviewed. A total of 64 esophageal cancer patients including 58 men and 6 women with mean age of 62.6 years were enrolled. Common presenting symptoms were dysphagia (74%), dyspepsia (10%) and hematemesis (8%). Mean duration of symptoms prior to diagnosis was 72 days. Esophageal stenosis with contact bleeding was the most common endoscopic finding (55.6%). The location of cancer was found in proximal (16%), middle (50%) and distal (34%) esophagus. Squamous cell carcinoma was far more common histology than adenocarcinoma (84.2% vs 10.5%). However, esophageal adenocarcinoma was significantly more common than squamous cell carcinoma in distal area of esophagus (100% vs 22.9%; p=0.0001, OR=1.6, 95%CI=1.1-2.2). Esophageal cancer stages 3 and 4 accounted for 35.2% and 59.3% respectively. Overall 2-year survival rate was 20% and only 16% in metastatic patients. Most esophageal cancer patients in Thailand have squamous cell carcinoma and nearly all present at advanced stage with a grave prognosis. Screening of high risk individuals and early detection might be important keys to improve the survival rate and treatment outcome in Thailand.

Objective: To investigate the cause of severe complications after arterial perfusion for esophageal cancer and the methods of prevention. Methods: 368 cases of esophageal cancer were treated with arterial perfusion of drugs for chemotherapy. The treatment numbers were 909 including 215 males and 153 females with the age ranging from 39 to 86. These patients were verified as esophageal cancers histopathologically. Selective angiography of the relevant esophageal segments and drugs for perfusion chemotherapy were undertaken. Results: The complications included one case of paralysis due to spinal cord injury, two cases with esophageal perforation and three cases of necrotic esophagitis. The case of paralysis died of original disease one month after the treatment. Of the cases of esophageal perforation, one formed the esophagus-trachea fistula and survived for eight months after being esophageal stent implantation and the other formed esophagus-mediastinum fistula and died of massive hemorrhage after six weeks. Three cases of necrotic esophagitis occurred at the normal segments of the esophagus and formed esophgeal perforation. Of these three cases, one formed esophago-bronchial fistula and survived up to now after creating drainage stoma of stomach. Two cases of the esophagus-mediastinum and esophagus-bronchus fistula died of severe infection. Conclusions: Severe complications of esophageal arterial catheterization with drugs for chemotherapy are rare. Less harmful, non-ionization contrast medium, low cellular toxicity drugs for chemotherapy with proper doses and concentrations should be selected together with optimal speed of infusion. Esophageal internal stent placement drainage stoma creation of stomach should be the useful adjunct for severe complications. (authors)

Purpose: Patients with esophageal and gastro-esophageal junction (GEJ) carcinomas suffer a high rates of local regional failure following conventional therapies. This report describes a unique institutional experience with the use of intraoperative radiation therapy (IORT) in the multimodality management of these tumors. Methods and Materials: From January, 1989 through August, 1994, 22 patients with distal esophageal(n=8) or GEJ junction carcinomas (n=14) underwent surgery followed by IORT to the tumor bed. Two patients died perioperatively of complications unrelated to the IORT and were excluded from the study. In the remaining 20 patients, IORT doses ranged from 12 to 20 Gy (median 15 Gy). The electron energies ranged from 4 to 22 MeV (median 6 MeV). Ten patients received no further radiation therapy (IORT only group), and ten patients received adjuvant external beam radiation (IORT + EB group) ranging from 39.6 to 60.8 Gy (median 45.0 Gy) in standard fractionation. 5-FU-based chemotherapy was administered to 15 patients either pre- or postoperatively. Follow-up ranged from 4 to 62 months (median 10 months). Results: The overall median survival time (MST) was 10 months. The overall 2-year actuarial survival rate was 25%. Distant metastasis developed in (9(20)) patients. The results by treatment subgroups are listed below. There was 1 local failure each in the IORT only group and the IORT+EB group. There were no perioperative complications related to IORT. The average length of hospital stay did not appear different than that of patients not receiving IORT. Conclusions: This is the first North American series describing the use of IORT after resection of esophageal/GEJ carcinomas. The use of IORT in our study did not increase perioperative morbidity over that reported for patients undergoing surgery alone. The addition of EBRT was associated with a longer median survival time although not with improved long-term survival when compared to the outcome of patients

Recently, novel endoscopic surgery, including endoscopic submucosal dissection (ESD), was developed to resect a large superficial gastrointestinal cancer. However, circumferential endoscopic surgery in the esophagus can lead to esophageal stricture that affects the patient's quality of life. This major complication is caused by scar formation, and develops during the two weeks after endoscopic surgery. We hypothesized that local administration of a controlled release anti-scarring agent can prevent esophageal stricture after endoscopic surgery. The aims of this study were to develop an endoscopically injectable anti-scarring drug delivery system, and to verify the efficacy of our strategy to prevent esophageal stricture. We focused on 5-Fluorouracil (5-FU) as an anti-scarring agent, which has already been shown to be effective not only for treatment of cancers, but also for treatment of hypertrophic skin scars. 5-FU was encapsulated by liposome, and then mixed with injectable 2% atelocollagen (5FLC: 5FU-liposome-collagen) to achieve sustained release. An in vitro 5-FU releasing test from 5FLC was performed using high-performance liquid chromatography (HPLC). Inhibition of cell proliferation was investigated using normal human dermal fibroblast cells (NHDF) with 5FLC. In addition, a canine esophageal mucosal resection was carried out, and 5FLC was endoscopically injected into the ulcer immediately after the operation, and compared with a similar specimen injected with saline as a control. 5-FU was gradually released from 5FLC for more than 2 weeks in vitro. The solution of 5-FU released from 5FLC inhibited NHDF proliferation more effectively than 5-FU alone. In the canine model, no findings of stricture were observed in the 5FLC-treated dog at 4 weeks after the operation and no vomiting occurred. In contrast, marked esophageal strictures were observed with repeated vomiting in the control group. Submucosal fibrosis was markedly reduced histologically in the 5FLC-treated

Esophagojejunal Anastomosis Fistula, Distal Esophageal Stenosis, and Metalic Stent Migration after Total Gastrectomy

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

Peroral endoscopic myotomy (POEM) is a newly developed, less invasive treatment for esophageal achalasia that requires general anesthesia under positive pressure ventilation. In this retrospective case series, we describe the anesthetic management of 28 consecutive patients who underwent POEM for esophageal achalasia. Anesthesia was maintained with sevoflurane and remifentanil under positive pressure ventilation through a tracheal tube. Retained contents in the esophagus were evacuated just before anesthesia induction to prevent regurgitation into the trachea. The POEM procedure was performed using an orally inserted flexible fiberscope. Elevation of end-tidal carbon dioxide after initiating esophageal carbon dioxide insufflation was observed in all patients and was treated by minute adjustments to the ventilation volume. Scopolamine butylbromide-induced tachycardia in one patient was treated with landiolol hydrochloride, which is a short-acting beta 1-selective blocker. Minor subcutaneous emphysema around the neck was observed in one patient. POEM was successfully completed, and tracheas were extubated immediately after the procedure in all patients. Our findings suggest that prevention of aspiration pneumonia during anesthesia induction, preparation for carbon dioxide insufflation-related complications, and treatment of scopolamine butylbromide-induced tachycardia play important roles in safe anesthesia management of POEM for esophageal achalasia.

Full Text Available Esophageal sclerosis is the most common visceral manifestation of systemic sclerosis, resulting in impaired esophageal clearance and retention of ingested food; in addition, co-existence of lung fibrosis with esophageal scleroderma is not uncommon. Both the progression of generalized connective tissue disorders and the damaging effect of chronic aspiration due to esophageal dysmotility appear to be involved in this procedure of interstitial fibrosis. Nifedipine is a widely prescribed calcium antagonist in a significant percentage of rheumatologic patients suffering from Raynaud syndrome, in order to inhibit peripheral vasospasm. Nevertheless, blocking calcium channels has proven to contribute to exacerbation of gastroesophageal reflux, which consequently can lead to chronic aspiration. We describe the case of severe exacerbation of interstitial lung disease in a 76-year-old female with esophageal sclerosis who was treated with oral nifedipine for Raynaud syndrome.

van Hoeij, Froukje B; Bredenoord, Albert J

2016-01-31

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.

The purpose of this study is to report our 5 year experience with fluoroscopic removal of blunt esophageal foreign body or impacted food in 15 consecutive patients who were referred by endoscopists because they couln't remove it endoscopically. The foreign body or impacted food was a piece of meat, a bean, a badug stone or a beef bone. Thirteen patients had underlying disease (11 of corrosive stricture, 2 of postopertive stricture) but 2 patient did not. We removed the object using one of the following 4 techniques: Basket extraction technique. Foley catheter technique, single balloon technique (dilatation of stenosis for passing the food into the stomach and for the treatment of the stricture as well), double balloon technique (removal of the foregin body by trapping it with two valvuloplasty balloons). Removal was successful in all patients. Esophageal performation occurred in one patient using the sibgle balloon technique, who treated nonoperatively by means of fasting, antibiotics and parenteral alimentation. No procedure related death occurred in these series. In conclusion, fliuroscopic removal of blunt esophageal foreign bodies of impacted food with various techniques is promising alternative to esophagoscopic removal

Radiation therapy (RT) plays an essential role in the management of esophageal cancer. Because the esophagus is a centrally located thoracic structure there is a need to balance the delivery of appropriately high dose to the target while minimizing dose to nearby critical structures. Radiation dose received by these critical structures, especially the heart and lungs, may lead to clinically significant toxicities, including pneumonitis, pericarditis, and myocardial infarction. Although technological advancements in photon RT delivery like intensity modulated RT have decreased the risk of such toxicities, a growing body of evidence indicates that further risk reductions are achieved with proton beam therapy (PBT). Herein we review the published dosimetric and clinical PBT literature for esophageal cancer, including motion management considerations, the potential for reirradiation, radiation dose escalation, and ongoing esophageal PBT clinical trials. We also consider the potential cost-effectiveness of PBT relative to photon RT.

Delayed esophageal perforation from stereotactic body radiation therapy for locally recurrent central nonsmall cell lung cancer

Directory of Open Access Journals (Sweden)

Sandeep Sainathan

2014-01-01

Full Text Available Stereotactic body radiation therapy (SBRT is a novel form of external beam radiation therapy. It is used to treat early and locally recurrent nonsmall cell lung cancer (NSLC in medically inoperable patients. It uses high dose, hypofractionated radiotherapy, with targeting of the tumor by precise spatial localization, thus minimizing injury to surrounding tissues. It can be safely used to ablate NSLC in both central and peripheral locations. We present two cases of delayed esophageal perforation after SBRT for locally recurrent central NSLC. The perforations occurred several months after the therapy. They were treated with covered esophageal stents, with mortality, due to the perforation in one of the patients. SBRT should be judiciously used to ablate centrally located NSLC and patients who develop episodes of esophagitis during or after SBRT, need to be closely followed with endoscopy to look for esophageal ulcerations. These ulcers should be closely followed for healing as these may degenerate into full thickness perforations several months after SBRT.

Objective: To retrospectively analyze the outcome of locally advanced non-small cell lung cancer patients treated with radiotherapy and chemoradiotherapy. Methods: 289 patients who were treated either by radiotherapy alone (168 patients) or radiotherapy plus chemotherapy (121 patients) from Dec. 1999 to Dec. 2002 were entered into the database for analysis. Pathological types: squamous cancer (152), adenocarcinoma(74), squamoadenocarcinoma(2) and other types (2). 24 showed cancer unclassificable and 35 were diagnosed without pathological proof. Stages: 74 had III A and 215 III B stage disease. Among the 121 patients treated with combined modality, 24 were treated with concurrent chemoradiotherapy, 78 radiotherapy after chemotherapy(C + R), and 19 radiotherapy followed by chemotherapy(R + C). In patients treated by concurrent chemoradiotherapy or C + R, 38 received consolidation chemotherapy after induction treatment. Results: The 1-, 3-, 5-year overall survival, and the median survival were: 45% , 16% , 8%, and 16.2 months for all patients; 57%, 27%, 11%, and 21.7 months for stage IIIA; 41%, 12%, 7%, and 15.3 months for IIIB. By logrank test, clinical stage, KPS performance, tumor volume, hemoglobin level before treatment, consolidation chemotherapy, radiation dose, and response to treatment showed statistically dramatic impact on overall survival. The overall survival rate and median survival time were slightly higher in the combined group than in the radiotherapy alone group, but the difference is statistically insignificant. In Cox multivariable regression, stage and consolidation chemotherapy were independent prognostic factors; KPS performance, radiation dose, and response to treatment were at the margin of statistical significance. Esophagitis and pneumonitis of Grade II or higher were 24% and 8%, respectively. Failure sites included in the thorax(41%), outside of thorax(48%), and both in and outside the thorax(11%). There was no difference between the

Denture Mis-swallowing in the Sliding Esophageal Hiatal Hernia Mimics Esophageal Perforation

2008-08-01

Full Text Available Mis-swallowing of a foreign body in the esophagus coexisting with sliding hernia might be misdiagnosed as esophageal perforation with mediastinal abscess. We report an 89-year-old woman, bedridden for a long period in a nursing home after a previous cerebrovascular accident, who was sent to our emergency department in a state of sepsis because she had swallowed a radio-opaque partial denture. The retention of the denture as an esophageal foreign body was complicated with mediastinitis and bilateral pleural effusion. The inability of the patient to give a reliable clinical history delayed the diagnosis. This report highlights the difficulty in precisely locating a partial denture because of conflicting radiologic findings and the coexistence of esophageal sliding hernia, all of which led to a misdiagnosis of possible esophageal perforation. A right posterolateral thoracotomy with gastrostomy was performed to remove the lower esophageal foreign body after esophagoscopy failed. The surgical finding of a coincidental sliding esophageal hiatal hernia correlated well with the clinical presentation. Managing such a complicated esophageal foreign body in this elderly patient was challenging.

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. Results in animal models that have used seeded scaffolds strongly suggest that seeding of both muscle and epithelial cells on scaffolds

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.

Esophageal complications are common in patients with systemic sclerosis (SSc). The relationship between gastroesophageal reflux (GER) symptoms and dysmotility was examined in endoscopically confirmed patients suspected of having reflux esophagitis. A total of 32 patients with limited and diffuse type SSc (lSSc, dSSc) were examined based on a structured questionnaire score (QS) of GER symptoms, retention fraction of esophageal scintigraphy at 90 s (R 90 ) and gastric emptying time. The QS was significantly higher in the reflux esophagitis group than in the non-esophagitis group (5.4±3.5, 1.4±2.9, P=0.003). When the non-esophagitis group was further divided into lSSc and dSSc groups, R 90 was higher in the reflux esophagitis group (31±18%) and the non-esophagitis group with dSSc (34±32%) than in the non-esophagitis group with lSSc (8±3%, P=0.02). Both high R 90 ≥15% and QS≥4 indicated reflux esophagitis. Conversely, both normal R 90 and QS indicated no reflux esophagitis. A combination of esophageal scintigraphy and structured questionnaire demonstrated different aspects of esophageal dysfunction, namely dysmotility and GER. Patients with high QS and dysmotility may be indicated for further evaluation including endoscopic examination and medical treatment.(author)

Endoscopic band ligation is the treatment of choice for bleeding esophageal varices. However it is not clear if this procedure is associated with less early and late mortality than sclerotherapy. To assess rates of re-bleeding and mortality in cohorts of patients with bleeding esophageal varices treated with endoscopic injection or band ligation. Analysis of medical records and endoscopy reports of two cohorts of patients with bleeding esophageal varices, treated between 1990 and 2010. Of these, 54 patients were treated with sclerotherapy and 90 patients with band ligation. A third cohort of 116 patients that did not require endoscopic treatment, was included. The mean analyzed follow up period was 2.5 years (range 1-16). Collection of data was retrospective for patients treated with sclerotherapy and prospective for patients treated with band ligation. Rates of re-bleeding and medium term mortality were assessed. During the month ensuing the first endoscopic treatment, re-bleeding was recorded in 39 and 72% of patients treated with band ligation and sclerotherapy, respectively (p < 0.01). The relative risk of bleeding after band ligation was 0.53 (95% confidence limits 0.390.73). Death rates until the end of follow up were 20 and 48% among patients with treated with band ligation and sclerotherapy, respectively (p < 0.01), with a relative risk of dying for patients subjected to band ligation of 0.41 (95% confidence limits 0.25-0.68). Band ligation was associated with lower rates of re-bleeding and mortality in these cohorts of patients.

Esophageal cancer occurs as either squamous cell carcinoma (ESCC) or adenocarcinoma. ESCCs comprise almost 90% of cases worldwide, and recur with a less than 15% five-year survival rate despite available treatments. The identification of new ESCC drivers and therapeutic targets is critical for improving outcomes. Here we report that expression of the human DEK oncogene is strongly upregulated in esophageal SCC based on data in the cancer genome atlas (TCGA). DEK is a chromatin-associated protein with important roles in several nuclear processes including gene transcription, epigenetics, and DNA repair. Our previous data have utilized a murine knockout model to demonstrate that Dek expression is required for oral and esophageal SCC growth. Also, DEK overexpression in human keratinocytes, the cell of origin for SCC, was sufficient to cause hyperplasia in 3D organotypic raft cultures that mimic human skin, thus linking high DEK expression in keratinocytes to oncogenic phenotypes. However, the role of DEK over-expression in ESCC development remains unknown in human cells or genetic mouse models. To define the consequences of Dek overexpression in vivo, we generated and validated a tetracycline responsive Dek transgenic mouse model referred to as Bi-L-Dek. Dek overexpression was induced in the basal keratinocytes of stratified squamous epithelium by crossing Bi-L-Dek mice to keratin 5 tetracycline transactivator (K5-tTA) mice. Conditional transgene expression was validated in the resulting Bi-L-Dek_K5-tTA mice and was suppressed with doxycycline treatment in the tetracycline-off system. The mice were subjected to an established HNSCC and esophageal carcinogenesis protocol using the chemical carcinogen 4-nitroquinoline 1-oxide (4NQO). Dek overexpression stimulated gross esophageal tumor development, when compared to doxycycline treated control mice. Furthermore, high Dek expression caused a trend toward esophageal hyperplasia in 4NQO treated mice. Taken together, these

Dysphagia is the earliest and the most common symptom of malignant disease in the esophagus. The palliative effects on dysphagia of radiotherapy (RT) and chemotherapy (CT) were evaluated retrospectively and compared with the effect of the self-expanding stent, evaluated in the prospective study. After completion of treatment, 78 (56%) of 140 patients treated with RT; 31 (49%) of 63 patients treated with CT; and 53 (81%) of 66 patients treated with stent insertion were free from dysphagia. Stent treatment has a good and prompt effect on dysphagia and can be recommended for palliation of patients with malignant esophageal strictures. (orig.).

Esophageal cancer (EC) 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 EC. Expert commentary: Of the 12 FDA-approved therapies in EC, 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.

The authors performed 27 fluoroscopically guided balloon dilatation in 12 patients of esophageal stricture during recent 3 years. The causes of esophageal stricture were corrosive esophagitis (N=2) and congenital narrowing (N=1), including postoperative narrowing in achalasia (N=3), esophageal varix (N=3), lye stricture (N=2) and esophageal cancer (N=1). Successful dilatation of the stricture was achieved during the procedure in 10 patients(83%). Major complication such as esophageal rupture was not found. The authors conclude that fluoroscopically guided esophageal balloon dilatation is a safe and effective method for treatment of symptomatic esophageal strictures.

Full Text Available Aortoesophageal fistulas are a rare but commonly fatal complication of esophageal cancer. Reports of successfully managed cases are few, with high mortality and morbidity usually resulting from failure to control the initial massive haemodynamic insult. We report the case of a 47-year-old Caucasian man with recently diagnosed advanced esophageal cancer who suffered an episode of massive haematemesis. Emergency gastroscopy revealed an arterial bleeding point in the proximal esophagus. A self-expanding metal esophageal stent was placed to achieve initial partial haemostasis. CT angiography confirmed an aortoesophageal fistula. An endoluminal stent device was thus inserted within the thoracic aorta stabilising the bleeding point. The patient subsequently made an uneventful recovery and was discharged on long-term antibiotics for palliative care. He survived for 2 months at home before dying of disseminated malignancy. The successful use of esophageal stenting as a means of achieving haemostasis, allowing time for endovascular intervention, is as yet a relatively unexplored area of management of this rare condition.

Patients with esophageal symptoms potentially associated to esophageal motor disorders such as dysphagia, chest pain, heartburn and regurgitation, represent one of the most frequent reasons for referral to gastroenterological evaluation. The utility of esophageal manometry in clinical practice is: (1) to accurately define esophageal motor function, (2) to identify abnormal motor function, and (3) to establish a treatment plan based on motor abnormalities. With this in mind, in the last decade, investigations and technical advances, with the introduction of high-resolution esophageal manometry, have enhanced our understanding and management of esophageal motility disorders. The following recommendations were developed to assist physicians in the appropriate use of esophageal manometry in modern patient care. They were discussed and approved after a comprehensive review of the medical literature pertaining to manometric techniques and their recent application. This position statement created under the auspices of the Gruppo Italiano di Studio per la Motilità dell'Apparato Digerente (GISMAD), Società Italiana di Gastroenterologia ed Endoscopia Digestiva (SIGE) and Associazione Italiana Gastroenterologi ed Endoscopisti Digestivi Ospedalieri (AIGO) is intended to help clinicians in applying manometric studies in the most fruitful manner within the context of their patients with esophageal symptoms.

Esophageal diverticula are uncommon lesions that are usually classified according to their location (cervical, thoracic, or epiphrenic), or underlying pathogenesis (pulsion or traction), and their morphology (true or false).The majority of esophageal diverticula are acquired lesions that occur predominantly in elderly adults. Pulsion, or false, diverticula are the most commonly encountered type of esophageal diverticula noticed at the level of cricopharyngeus muscle, occur as a localized outpouchings that lacks a muscular coat, and as such their wall is formed entirely by mucosa and submucosa. True, or traction, esophageal diverticulum (TED) is seen in the middle one third of the thoracic esophagus in a peribronchial location, occurs secondary to mediastinal inflammatory lesions such as tuberculosis or histoplasmosis. The resultant desmoplastic reaction in the paraesophageal tissue causes full thickness pinching on the esophageal wall, producing a conical, broad-mouthed true diverticulum. They often project to the right side because subcarinal lymph nodes in this area are closely associated with the right anterior wall of the esophagus. TED usually presents with symptoms such as dysphagia, postural regurgitation, belching, retrosternal pain, heartburn, and epigastric pain. As in patients with pharyngoesophageal (Zenker's) diverticula, pulmonary symptoms are often present but underestimated in TED patients. These symptoms range from mild nocturnal cough to life-threatening massive aspiration. In this particular report we describe a rare case of TED presenting as a symptomatic upper gastrointestinal bleeding. Diagnostic evaluation of TED includes chest X-ray, barium esophagogram and manometry. A significant proportion of lower esophageal diverticula are associated with motility disorders. Management of TED include treating the underlying cause sometimes a surgical resection of diverticulum along with esophageal myotomy is necessitated in symptomatic patients.

Objective: To compare the clinical effectiveness of intraluminal radiation stent with that of common covered stent to palliate dysphagia in advanced esophageal cancer. Methods: Fifty three cases were randomly assigned to the experimental group (Group A, n=27) and the control group (Group B, n26). Radiation stents were placed in Group A and common covered stents were placed in Group B. A randomized trial was performed to compare the two groups with respect to complications, relief of dysphagia, and overall survival period. Results: The placement of stents were successful in all the 53 patients. In Group A, no leakage of radiation source was observed through ECT examination, and no displacement of radiation seeds was found through radiography. The follow-up CT showed reduced lesion size compared to presurgical lesion. Three of the 5 patients who underwent uncovered radiation stent placement showed complete necrosis and inflammatory hyperblastosis in tumor tissue adjacent to radiation particles at 2 months follow-up. The lumen of the stents were smooth and had no overgrowth of tumor tissue. Granulation hyperplasia was found at both ends of the stents, prominent at the proximal ends, The incidence of stent- related complications had no significant difference between group A and group B (test, P>0.05). Dysphasia resolved significantly after stent placement in both groups. The improvement of dysphasia was more significant in Group A than in Group B after 2 months of stent placement (1.37±0.56 in group A, 1.82±0.50 in group B,P=0.004). The median survival period was longer in Group A than in Group B (7 months vs 4 months ). The mean survival period was also longer in Group A than in Group B (8.3 months vs 3.5 months). There was a statistically significant difference in the survival period between the two groups (P<0.01). Conclusion: Intraluminal radiation esophageal stent can not only palliate dysphagia but also restrain tumor growth. Palliation period of dysphagia and

Role of metallic stents in benign esophageal stricture

Simple esophageal strictures, which are focal, straight, and large in diameter, usually require 1 - 3 dilation sessions to relieve symptoms. However, complex strictures, which are long, tortuous, or associated with a severely compromised luminal diameter, are usually more difficult to treat with conventional bougie or balloon dilation techniques, and often have high recurrence rates. Although the permanent placement of self-expandable metal stents (SEMS) has been used to manage refractory benign esophageal strictures, this procedure is associated with additional problems, such as stricture from tissue hyperplasia, stent migration, and fistula formation. Thus, several new types of stents have been developed, including temporary SEMS, self-expandable plastic stents (SEPS), and biodegradable stents. The use of these new products has produced varied results. Temporary SEMS that have been used to relieve benign esophageal conditions have caused granulation tissue at both ends of the stent because of contact between the mucosa and the exposed metal components of the stent, thus hindering stent removal. We examined the tissue response to two new types of SEMS, a flange-type and a straighttype, each coated with a silicone membrane on the outside of the metal mesh. These two SEMS were evaluated individually and compared with a conventional control stent in animal experiments. Although the newly designed stents resulted in reduced tissue hyperplasia, and were thus more easily separated from the esophageal tissue, some degree of tissue hyperplasia did occur. We suggest that newly designed DES (drug-eluting stents) may provide an alternative tool to manage refractory benign esophageal stricture.

Cytoprotective effects of hydrogen sulfide in novel rat models of non-erosive esophagitis.

Directory of Open Access Journals (Sweden)

Oksana Zayachkivska

Full Text Available Non-erosive esophagitis is a chronic inflammatory condition of the esophagus and is a form of gastroesophageal reflux disease. There are limited treatment options for non-erosive esophagitis, and it often progresses to Barrett's esophagus and esophageal carcinoma. Hydrogen sulfide has been demonstrated to be a critical mediator of gastric and intestinal mucosal protection and repair. However, roles for H2S in esophageal mucosal defence, inflammation and responses to injury have not been reported. We therefore examined the effects of endogenous and exogenous H2S in rat models of non-erosive esophagitis. Mild- and moderate-severity non-erosive esophagitis was induced in rats through supplementation of drinking water with fructose, plus or minus exposure to water-immersion stress. The effects of inhibitors of H2S synthesis or of an H2S donor on severity of esophagitis was then examined, along with changes in serum levels of a pro- and an anti-inflammatory cytokine (IL-17 and IL-10, respectively. Exposure to water-immersion stress after consumption of the fructose-supplemented water for 28 days resulted in submucosal esophageal edema and neutrophil infiltration and the development of lesions in the muscular lamina and basal cell hyperplasia. Inhibition of H2S synthesis resulted in significant exacerbation of inflammation and injury. Serum levels of IL-17 were significantly elevated, while serum IL-10 levels were reduced. Treatment with an H2S donor significantly reduced the severity of esophageal injury and inflammation and normalized the serum cytokine levels. The rat models used in this study provide novel tools for studying non-erosive esophagitis with a range of severity. H2S contributes significantly to mucosal defence in the esophagus, and H2S donors may have therapeutic value in treating esophageal inflammation and injury.

Chemoradiotherapy is the most common treatment for inoperable esophageal cancer. However, there is no consensus on the delineation of the clinical target volume. Elective nodal irradiation (ENI) is recommended for inoperable esophageal cancer. A few studies have reported a decrease in the incidence of radiation-related toxicity of involved-field irradiation (IFI) for esophageal cancer. A systematic review and pooled analysis were performed to determine whether IFI in definitive chemoradiotherapy was more beneficial than ENI for esophageal cancer. The results showed no significant differences in the overall survival and local control rates between the IFI and ENI arms. Meanwhile, the incidences of esophageal and lung toxicities were significantly decreased in the IFI arm. These results suggest that IFI is a feasible treatment option for locally advanced esophageal cancer, especially to minimize irradiation-related toxicity.

Button battery lodged in the esophagus carries a high risk of morbidity and mortality. The purpose of this study was to present cases of patients with esophageal button battery ingestion treated at our clinic and to emphasize the importance of early diagnosis and treatment. Records of patients admitted to our hospital for foreign body ingestion between January 2010 and May 2015 were retrospectively reviewed. Cases with button battery lodged in the esophagus were included in the study. Patient data regarding age, sex, length of time after ingestion until admission, presenting clinical symptoms, type and localization of the battery, management, and prognosis were analyzed. Among 1891 foreign body ingestions, 71 were localized in the esophagus, and 8 of those (11.2%) were cases of button battery ingestion. Mean age was 1.7 years. Admission was within 6 hours of ingestion in 5 cases, after 24 hours had elapsed in 2, and 1 month after ingestion in 1 case. All patients but 1 knew the history of ingestion. Prompt endoscopic removal was performed for all patients. Three patients developed esophageal stricture, which responded to dilatation. Early recognition and timely endoscopic removal is mandatory in esophageal button battery ingestion. It should be suspected in the differential diagnosis of patients with persistent respiratory and gastrointestinal symptoms.

We present a case in which we used a thoracoscopic approach for resection of multiple esophageal carcinomas diagnosed 33 years after surgery for esophageal achalasia. 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.

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

A 59-year-old man with metastatic an esophageal tumor from hepatocellular carcinoma (HCC) presented with progressive dysphagia. He had undergone liver transplantation for HCC three and a half years prevously. At presentation, his radiological and endoscopic examinations suggested a submucosal tumor in the lower esophagus, causing a luminal stricture. We performed complete resection of the esophageal metastases and esophagogastrostomy reconstruction using the da Vinci robotic system. Recovery was uneventful and he was been doing well 2 mo after surgery. α-fetoprotein level decreased from 510 ng/mL to 30 ng/mL postoperatively. During the follow-up period, he developed a recurrent esophageal stricture at the anastomosis site and this was successfully treated by endoscopic esophageal dilatation. PMID:21765971

Full Text Available BACKGROUND: Few data are available on the prevalence of erosive and severe esophagitis in Western countries. OBJECTIVE: To retrospectively determine the prevalence and the factors predicting erosive esophagitis and severe esophagitis in a large series of endoscopies in Spain. DESIGN: Retrospective observational study. A multivariate analysis was performed to determine variables predicting severe esophagitis. SETTING: Databases of 29 Spanish endoscopy units. PATIENTS: Patients submitted to a diagnostic endoscopy during the year 2005. INTERVENTIONS: Retrospective review of the databases. MAIN OUTCOME MEASUREMENTS: Esophagitis severity (graded according to the Los Angeles classification and associated endoscopic findings. RESULTS: Esophagitis was observed in 8.7% of the 93,699 endoscopies reviewed. Severe esophagitis (LA grade C or D accounted for 22.5% of cases of the disease and was found in 1.9% of all endoscopies. Incidences of esophagitis and those of severe esophagitis were 86.2 and 18.7 cases per 100,000 inhabitants per year respectively. Male sex (OR 1.89 and advanced age (OR 4.2 for patients in the fourth age quartile were the only variables associated with severe esophagitis. Associated peptic ulcer was present in 8.8% of cases. LIMITATIONS: Retrospective study, no data on individual proton pump inhibitors use. CONCLUSIONS: Severe esophagitis is an infrequent finding in Spain. It occurs predominantly in males and in older individuals. Peptic ulcer disease is frequently associated with erosive esophagitis.

The efficacy of endoscopic screening for esophageal cancer in patients with hypopharyngeal cancer remains controversial and its impact on prognosis has not been adequately discussed. We studied the use of endoscopic screening to detect esophageal cancer in hypopharyngeal cancer patients by analyzing the incidence, stage and prognosis. We included 64 patients with hypopharyngeal cancer who received radical radiotherapy at our institute. Chromoendoscopic esophageal examinations with Lugol dye solution were routinely performed at and after treatment for hypopharyngeal cancer. Twenty-eight esophageal cancers were detected in 28 (41%) patients (18 synchronous and 10 metachronous cancers). Of the 28 cancers, 23 were stage 0 or I cancer and 15 of these were treated with endoscopic resection. Local control was achieved in all of these 23 stage 0 or I cancers. The 5-year overall survival rates with esophageal cancer were 83% in stage 0, 47% in stage I and 0% in stage IIA-IVB. This study showed a strikingly high incidence of esophageal cancer in hypopharyngeal cancer patients. We suppose that the combination of early detection by chromoendoscopic examination and endoscopic resection for associated esophageal cancer in hypopharyngeal cancer patients improve prognosis and maintain quality of life.

Esophageal cancer ranks among the most aggressive malignant diseases. The limited improvements in treatment outcomes provided by conventional therapies have prompted us to seek innovative strategies for treating this cancer. More than 100 trillion microorganisms inhabit the human intestinal tract and play a crucial role in health and disease conditions, including cancer. The human intestinal microbiome is thought to influence tumor development and progression in the gastrointestinal tract by various mechanisms. For example, Fusobacterium nucleatum , which primarily inhabits the oral cavity and causes periodontal disease, might contribute to aggressive tumor behavior through activation of chemokines such as CCL20 in esophageal cancer tissue. Composition of the intestinal microbiota is influenced by diet, lifestyle, antibiotics, and pro- and prebiotics. Therefore, by better understanding how the bacterial microbiota contributes to esophageal carcinogenesis, we might develop novel cancer prevention and treatment strategies through targeting the gastrointestinal microflora. This review discusses the current knowledge, available data and information on the relationship of microbiota with esophagitis, Barrett's esophagus, esophageal adenocarcinoma and squamous cell carcinoma.

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%(P0.05). 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.

Full Text Available We present a case in which we used a thoracoscopic approach for resection of multiple esophageal carcinomas diagnosed 33 years after surgery for esophageal achalasia. 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.

Abstract 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 ...

One of the primary dose-limiting toxicities during thoracic irradiation is acute esophagitis (AE). The aim of this study is to investigate dosimetric and clinical predictors for AE grade ≥ 2 in patients treated with accelerated radiotherapy for locally advanced non-small cell lung cancer (NSCLC). 66 NSCLC patients were included in the present analysis: 4 stage II, 44 stage IIIA and 18 stage IIIB. All patients received induction chemotherapy followed by dose differentiated accelerated radiotherapy (DART-bid). Depending on size (mean of three perpendicular diameters) tumors were binned in four dose groups: <2.5 cm 73.8 Gy, 2.5–4.5 cm 79.2 Gy, 4.5–6 cm 84.6 Gy, >6 cm 90 Gy. Patients were treated in 3D target splitting technique. In order to estimate the normal tissue complication probability (NTCP), two Lyman models and the cutoff-logistic regression model were fitted to the data with AE ≥ grade 2 as statistical endpoint. Inter-model comparison was performed with the corrected Akaike information criterion (AIC c ), which calculates the model’s quality of fit (likelihood value) in relation to its complexity (i.e. number of variables in the model) corrected by the number of patients in the dataset. Toxicity was documented prospectively according to RTOG. The median follow up was 686 days (range 84–2921 days), 23/66 patients (35 %) experienced AE ≥ grade 2. The actuarial local control rates were 72.6 % and 59.4 % at 2 and 3 years, regional control was 91 % at both time points. The Lyman-MED model (D50 = 32.8 Gy, m = 0.48) and the cutoff dose model (D c = 38 Gy) provide the most efficient fit to the current dataset. On multivariate analysis V38 (volume of the esophagus that receives 38 Gy or above, 95 %-CI 28.2–57.3) was the most significant predictor of AE ≥ grade 2 (HR = 1.05, CI 1.01–1.09, p = 0.007). Following high-dose accelerated radiotherapy the rate of AE ≥ grade 2 is slightly lower than reported for concomitant radio-chemotherapy with the

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

Diabetes mellitus can cause various gastrointestinal symptoms. Assessment of esophageal dysmotility in diabetic patients has been scarcely studied. The aim of this study was to determine the esophageal motor characteristics of diabetic versus nondiabetic patients who present with dysphagia. High-resolution esophageal manometries (HREMs) of 83 diabetic patients and 83 age and gender-matched nondiabetic patients with dysphagia from 2 medical centers were included in this study. Demographic information, medical comorbidities, and medication usage were recorded for each patient in a single registry. HREM of each patient was evaluated and the different functional parameters were recorded. Overall, 46% of diabetic patients were found to have an esophageal motor disorder. Diabetic patients with dysphagia were more likely to have failed swallows on HREM (50.6% vs. 33.7%; P=0.03) as compared with nondiabetic patients. Among diabetic patients, those being treated with insulin were more likely to have failed (69.0% vs. 40.7%; P=0.01) and weak (65.5% vs. 33.3%; P=0.005) swallows as compared with diabetic patients not on insulin. Among diabetic patients, those with abnormal manometry were more likely to demonstrate diabetic retinopathy (27.0% vs. 8.7%; P=0.04). There was a trend toward increased incidence of esophagogastric junction outflow obstruction in diabetic patients (10.8% vs. 2.4%; P=0.057) as compared with nondiabetic patients. Nearly half of diabetic patients with dysphagia have some type of an esophageal motility disorder. Diabetic retinopathy and the use of insulin are predictive of esophageal motor abnormalities among diabetic patients.

Full Text Available Abstract Background Selective decontamination of the digestive tract (SDD to eliminate gram-negative bacteria is still not widely accepted, although it reduces the incidence of nosocomial infections. In a previous retrospective study, a clear benefit to perioperative morbidity, and a reduction in nosocomial infections were found in patients who underwent an esophageal anastomosis. Thus, SDD was applied routinely for esophageal anastomoses. We report the outcome of a cohort of 81 patients who underwent this treatment. Methods From 2002, patients who underwent an esophageal anastomosis (esophagojejunostomy were prospectively recorded. Perioperatively, patients received polymyxin, tobramycin, vancomycin and nystatin by mouth four times a day. Outcome was compared to a control group that was treated before 2002 (68 patients without SDD and 53 patients with SDD. Postoperative morbidity and mortality were assessed. Results Between 2002 and 2007, 81 patients who underwent an esophageal anastomosis received SDD. Compared to a retrospective control group, patients with SDD had significantly less pneumonia (OR 0.06 (0.01-0.46, p Conclusions SDD significantly reduces perioperative morbidity and mortality in patients who undergo a distal esophageal anastomosis compared to a historical control group. In patients with an anastomotic leakage, there was a strong tendency of SDD to reduce postoperative mortality.

OBJECTIVE To evaluate perioperative morbidity and outcome in dogs and cats undergoing esophageal surgery. DESIGN Retrospective case series. ANIMALS 63 client-owned dogs and 9 client-owned cats. PROCEDURES Medical records of dogs and cats that underwent esophageal surgery were reviewed for information on signalment, history, results of preoperative diagnostic testing, condition treated, details of surgery, intraoperative complications, and postoperative complications. Long-term follow-up data were obtained via veterinarian and client telephone conversations. The relationship between complications and survival to hospital discharge was evaluated by means of regression analysis. RESULTS The most common indication for surgical intervention was an esophageal foreign body in dogs (50/63 [79%]) and esophageal stricture in cats (3/9). Complications were documented in 54% (34/63) of dogs and 3 of 9 cats. The most common immediate postoperative complications were respiratory in nature (9 dogs, 1 cat). Partial esophagectomy and resection with anastomosis were significantly associated with the development of immediate postoperative complications in dogs. The most common delayed postoperative complications were persistent regurgitation (7 dogs) and esophageal stricture formation (3 dogs, 1 cat). For dogs, a mass lesion and increasing lesion size were significantly associated with the development of delayed postoperative complications. Six dogs (10%) and 1 cat died or were euthanized prior to discharge, and pneumomediastinum and leukopenia were negative prognostic factors for dogs being discharged from the hospital. CONCLUSIONS AND CLINICAL RELEVANCE Results of this study suggested that the short-term prognosis for dogs and cats that survive surgery for treatment of esophageal lesions is favorable, with 90% of patients discharged from the hospital (57/63 dogs; 8/9 cats). However, dogs treated for more extensive esophageal lesions as well as those undergoing esophagectomy or

Esophageal cancer ranks eighth in order of cancer occurrence. Its lethality primarily stems from inability to detect the disease during the early organ-confined stage and the lack of effective therapies for advanced-stage disease. Moreover, the understanding of molecular processes involved in esophageal cancer is not complete, hampering the development of efficient diagnostics and therapy. Efforts made by the scientific community to improve the survival rate of esophageal cancer have resulted in a wealth of scattered information that is difficult to find and not easily amendable to data-mining. To reduce this gap and to complement available cancer related bioinformatic resources, we have developed a comprehensive database (Dragon Database of Genes Implicated in Esophageal Cancer) with esophageal cancer related information, as an integrated knowledge database aimed at representing a gateway to esophageal cancer related data. Manually curated 529 genes differentially expressed in EC are contained in the database. We extracted and analyzed the promoter regions of these genes and complemented gene-related information with transcription factors that potentially control them. We further, precompiled text-mined and data-mined reports about each of these genes to allow for easy exploration of information about associations of EC-implicated genes with other human genes and proteins, metabolites and enzymes, toxins, chemicals with pharmacological effects, disease concepts and human anatomy. The resulting database, DDEC, has a useful feature to display potential associations that are rarely reported and thus difficult to identify. Moreover, DDEC enables inspection of potentially new 'association hypotheses' generated based on the precompiled reports. We hope that this resource will serve as a useful complement to the existing public resources and as a good starting point for researchers and physicians interested in EC genetics. DDEC is freely accessible to academic

From 1975 to 1983, a total of 51 cases of esophageal cancer with T2 ∼ T3 in TNM classification, were treated by radiotherapy alone or combined chemotherapy. All 51 patients received total dose of 60 ∼ 70 GY for 6 ∼ 8 weeks and 20 out of 51 were treated by radiotherapy plus chemotherapy (5FU or UFT and/or bleomycin or pepleomycin). The 2-year-survival rate was slightly better in patients treated by radiotherapy plus chemotherapy than in patients treated by radiotherapy alone, but this difference was not significant. (author)

To quantitate esophageal transit of the achalasia patients after Heller's myotomy using scintigraphic technique. After a bolus ingestion of 10 ml orange juice containing 185 MBq 99m Tc-DTPA, radioactivity was measured on the esophagus for 5 minutes by SPECT, and esophageal clearance rate was calculated. Forty-two patients and 10 normal controls were included. Esophageal transit was increased significantly after Heller's operation, but it was still lower than normal value. Heller's myotomy can significantly improve esophageal transit in the patients with achalasia, although it does not reach normal level

Objective: To evaluate the methods and effect of retrievable self-expanding esophageal stent in treating benign esophageal stenosis of children. Methods: The covered retrievable expandable nitinol stents were placed in 10 children with corrosive esophageal stenosis and post-anastomotic stenosis, age ranged from 2 to 12 years, the dysphagia scores were 3, Barium esophagography was taken before the use of retrievable stent. Results: The stents were placed safely in all patients without complications and were successfully removed after all. After the stent placement, all patients could take solid food without dysphagia. During 6 to 12 months follow-up after the stent removal, all children could eat satisfactorily with the dysphagia score as 0. Conclusion: The use of covered retrievable expandable stent is effective and safe in treating childhood benign esophageal stenosis. (authors)

Eosinophilic esophagitis (EE) is an inflammatory condition characterized by intense eosinophilic infiltration of the esophagus. EE is frequently misdiagnosed as gastroesophageal reflux disease. Here, we present a child with EE and a characteristic endoscopic finding, r inged esophagus . An 11-year-old Saudi boy presented with dysphagia for 1 year. He had experienced an intermittent sensation of solid food sticking in his chest, which was relieved by drinking liquids. A barium swallow excluded anatomical causes of dysphagia, but revealed multiple-ringed esophagus. Endoscopy showed a furrowing and trachealizing appearance of the entire esophagus. Hisologically, extensive eosinophilic infiltration was a feature in biopsies obtained from the esophagus. The child responded well to a 2-month course of inhaled fluticasone. Symptoms recurred 3 months after discontinuation of therapy, which necessitated resumption of inhaled fluticasone. The endoscopic appearance of multiple esophageal rings should raise suspicion of EE and be confirmed by esophageal biopsies. (author)

This study investigated the impact of radiotherapy on swallowing function in 152 patients with esophageal cancer. Swallowing function was retrospectively assessed in these patients using a swallowing-function scoring system. Total tumor dose ranged from 22.5 Gy in 14 fractions to 104.4 Gy in 50 fractions. Improvement in dysphagia was noted in 62.3% of these patients, with a median time to improvement of 6 weeks. Improvement rate of patients irradiated with 20.0 to 34.9 Gy, 35.0 to 59.9 Gy and 60.0 Gy or more was 23.1%, 58.3% and 71.6%, respectively. Patients with T1-3 showed, a greater improvement rate than patients with T4 cancer (72.2% versus 54.1%). On multivariate analysis, the initial score, total dose and T factor correlated with improvements in swallowing function. Our results suggest that 35.0 Gy or more is necessary to improve swallowing function. The median duration in which patients could swallow soft or solid foods, was 8 months in patients receiving 60.0 Gy or more and 2 months in patients receiving 50.0 to 59.9 Gy, respectively. There was a significant difference between these periods (p<0.01). Regarding duration of palliation, median duration for patients receiving 60.0 Gy or more was 30 weeks, while it was 22 weeks for patients treated with lesser doses (p=0.053). We recommend 60.0 Gy or more as the optimal dosage for improving dysphagia. (author)

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. Two grade II or higher complications occurred, including one patient who was readmitted on postoperative day 4 with a leak requiring a thoracotomy. After a mean follow-up of 13.6 +/- 3.0 months (range 3-36 months), two patients complained of mild solid food dysphagia and one patient required proton pump inhibitor (PPI) for gastroesophageal reflux disease (GERD) symptoms. The majority of patients

Primary Esophageal Motility Disorders: Beyond Achalasia.

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

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

Purpose: To determine the impact of 18-F-fluoro-deoxy-D-glucose positron emission tomography (FDG-PET) in the staging and prognosis of patients with locally advanced esophageal cancer (LAEC). Methods and Materials: Between January 2000 and October 2004, all patients with LAEC evaluated in the Department of Radiation Oncology were considered for enrollment into a Phase II trial of preoperative chemoradiation. Entry required a staging whole-body FDG-PET scan. Results: One hundred ten consecutive patients were evaluated; 38 were ineligible for reasons including treatment elsewhere, prior malignancy, or refusal of treatment. After conventional staging (clinical examination, endoscopic ultrasound, and chest/abdominal computerized tomography), 33 patients were ineligible because of metastatic disease or poor performance status. Of the remaining 39 patients, 23 were confirmed to have LAEC after FDG-PET staging and were treated in the Phase II trial (Cohort I). Sixteen patients, however, had FDG-PET findings consistent with occult metastatic disease and were deemed ineligible for the trial but were treated with curative intent (Cohort II). The 2-year survival rate for the 23 patients in Cohort I was 64%, compared with 17% (p = 0.003) for patients in Cohort II (FDG-PET positive). Conclusions: More than one-third of patients determined to have LAEC with conventional staging were upstaged with the use of FDG-PET. Despite comparable therapy, upstaging with FDG-PET predicts poor 2-year survival

Purpose: To compare radiotherapy treatment plans for mid- and distal-esophageal cancer with primary involvement of the gastroesophageal (GE) junction using a novel IMRT and Arc technique (IMRT and Arc), helical tomotherapy (HT), and RapidArc (RA1 and RA2). Methods and materials: Eight patients treated on HT for locally advanced esophageal cancer with radical intent were re-planned for RA and IMRT and Arc. RA plans employed single and double arcs (RA1 and RA2, respectively), while IMRT and Arc plans had four fixed-gantry IMRT fields and a conformal arc. Dose-volume histogram statistics, dose uniformity, and dose homogeneity were analyzed to compare treatment plans. Results: RA2 plans showed significant improvement over RA1 plans in terms of OAR dose and PTV dose uniformity and homogeneity. HT plan provided best dose uniformity (p = 0.001) and dose homogeneity (p = 0.002) to planning target volume (PTV), while IMRT and Arc and RA2 plans gave lowest dose to lungs among four radiotherapy techniques with acceptable PTV dose coverage. Mean V 10 of the lungs was significantly reduced by the RA2 plans compared to IMRT and Arc (40.3%, p = 0.001) and HT (66.2%, p 15 of the lungs for the RA2 plans also showed significant improvement over the IMRT and Arc (25.2%, p = 0.042) and HT (34.8%, p = 0.027) techniques. These improvements came at the cost of higher doses to the heart volume compared to HT and IMRT and Arc techniques. Mean lung dose (MLD) for the IMRT and Arc technique (21.2 ± 5.0% of prescription dose) was significantly reduced compared to HT (26.3%, p = 0.004), RA1 (23.3%, p = 0.028), and RA2 (23.2%, p = 0.017) techniques. Conclusion: The IMRT and Arc technique is a good option for treating esophageal cancer with thoracic involvement. It achieved optimal low dose to the lungs and heart with acceptable PTV coverage. HT is a good option for treating esophageal cancer with little thoracic involvement as it achieves superior dose conformality and uniformity. The RA2

Purpose: To test the hypothesis that TS3'UTR polymorphisms predict outcomes in 146 Caucasian patients with esophageal adenocarcinoma treated with preoperative 5-fluorouracil-based chemoradiation. Methods and Materials: DNA was extracted from hematoxylin-and-eosin stained histologic slides of normal esophageal or gastric mucosa sections from paraffin blocks of esophagectomy specimens. Genotypes of the TS3'UTR polymorphism were determined by polymerase chain reaction for a 6-bp insertion. The genotype groups (0bp/0bp, 6bp/0bp, and 6bp/6bp) were compared for clinical features and overall survival, recurrence-free-survival, locoregional control (LRC), and distant metastasis control. Multivariable Cox regression analyses were performed to find independent predictors for the stated outcomes. Results: There was a trend of association between 6bp/6bp genotype and a decreased risk of local regional recurrence (hazards ratio = 0.211, 95% confidence interval = 0.041-1.095, p = 0.06) compared with other genotypes. There was a trend that patients with 6bp/6bp genotype had a higher 3-year probability of LRC compared with patients with the other two genotypes combined (p = 0.07); however, the difference was not statistically significant. Conclusions: The null hypotheses were not rejected in this study, probably owing to small sample size or the single gene examined. Prospective studies with adequate statistical power analyzing a family of genes involved in the 5-fluorouracil metabolism are needed to assess genetic determinants of treatment-related outcomes in esophageal adenocarcinoma

Feeding Problems and Their Underlying Mechanisms in the Esophageal Atresia–Tracheoesophageal Fistula Patient

Feeding difficulties such as dysphagia, coughing, choking, or vomiting during meals, slow eating, oral aversion, food refusal, and stressful mealtimes are common in children with repaired esophageal atresia (EA) and the reasons for this are often multifactorial. The aim of this review is to describe the possible underlying mechanisms contributing to feeding difficulties in patients with EA and approaches to management. Underlying mechanisms for these feeding difficulties include esophageal dysphagia, oropharyngeal dysphagia and aspiration, and aversions related to prolonged gastrostomy tube feeding. The initial diagnostic evaluation for feeding difficulties in a patient with EA may involve an esophagram, videofluoroscopic imaging or fiberoptic endoscopic evaluation during swallowing, upper endoscopy with biopsies, pH-impedance testing, and/or esophageal motility studies. The main goal of management is to reduce the factors contributing to feeding difficulties and may include reducing esophageal stasis, maximizing reflux therapies, treating underlying lung disease, dilating strictures, and altering feeding methods, routes, or schedules.

The objective of this study was to investigate the significance of hedgehog signaling pathway in chemoradiotherapy sensitivity and its effect on the prognosis of esophageal squamous cell carcinoma. In the present study, we used the method of immunohistochemistry to examine the expression status of two hedgehog components, PTCH1 and glioma-associated oncogene GLI-1, in 100 pre-treated biopsy specimens of esophageal squamous cell carcinoma patients treated with definitive chemoradiotherapy. We find that high levels of PTCH1 and GLI-1 were detected in 76.0 and 72.0% of esophageal squamous cell carcinoma, respectively. Significant associations of high PTCH1 and GLI-1 expression with large tumor size (both P=0.01), locoregional progression (P=0.001 and 0.003, respectively) and the lack of complete response to chemoradiotherapy (P=0.008 and 0.01, respectively) were observed. Univariate analysis revealed that high PTCH1 and GLI-1 expression was associated with poor locoregional progression-free survival, distant progression-free survival and overall survival. Furthermore, esophageal squamous cell carcinoma patients with high PTCH1 and GLI-1 expression have the shorter survival time than the subgroups with negative and low PTCH1 and GLI-1 expression. In multivariate analysis, PTCH1 and GLI-1 expression status were both evaluated as independent prognostic factors for locoregional progression-free survival, distant progression-free survival and overall survival. These findings suggest an important role for the activation of hedgehog signaling in esophageal squamous cell carcinoma progression and that PTCH1 and GLI-1 expression may be significantly associated with esophageal squamous cell carcinoma resistance to chemoradiotherapy.

Anti-EGFR-Targeted Therapy for Esophageal and Gastric Cancers: An Evolving Concept

Full Text Available Cancers of the esophagus and stomach present a major health burden worldwide. In the past 30 years we have witnessed some interesting shifts in terms of epidemiology of esophago gastric cancers. Regardless of a world region, the majority of patients diagnosed with esophageal or gastric cancers die from progression or recurrence of their disease. While there are many active cytotoxic agents for esophageal and stomach cancers, their impact on the disease course has been modest at best. Median survival for patients with advanced gastroesophageal cancer is still less than a year. Therefore, novel strategies, based on our understanding of biology and genetics, are desperately needed. Epidermal growth factor receptor (EGFR pathway has been implicated in pathophysiology of many epithelial malignancies, including esophageal and stomach cancers. EGFR inhibitors, small molecule tyrosine kinase inhibitors and monoclonal antibodies, have been explored in patients with esophageal and gastric cancers. It appears that tumors of the distal esophagus and gastroesophageal junction (GEJ may be more sensitive to EGFR blockade than distal gastric adenocarcinomas. Investigations looking into potential molecular predictors of sensitivity to EGFR inhibitors for patients with esophageal and GEJ cancers are ongoing. While we are still searching for those predictors, it is clear that they will be different from ones identified in lung and colorectal cancers. Further development of EGFR inhibitors for esophageal and GEJ cancers should be driven by better understanding of EGFR pathway disregulation that drives cancer progression in a sensitive patient population.

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), Pheartburn 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.

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 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 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 clinical

The prognoses of submucosal esophageal squamous cell carcinoma patients vary. Patients with favorable prognoses may receive less invasive or nonsurgical interventions, whereas patients with poor prognoses or advanced esophageal cancer may require aggressive treatments. We sought to identify prognostic factors for patients with submucosal esophageal squamous cell carcinoma, focusing on lymph node metastasis and recurrence. We included 137 submucosal esophageal squamous cell carcinoma patients who had undergone transthoracic esophagectomy with systematic extended lymph node dissection. Submucosal tumors were classified as SM1, SM2, and SM3 according to the depth of invasion. Prognostic factors were determined by univariable and multivariable analyses. Lymph node metastasis was observed in 18.8%, 30.5%, and 50.0% of SM1, SM2, and SM3 cases, respectively. The overall 5-year recurrence rate was 21.9%; the rates for SM1, SM2, and SM3 tumors were 9.4%, 18.6%, and 34.8%, respectively. The SM1 tumors all recurred locoregionally; distant metastasis occurred in SM2 and SM3 cases. The 5-year overall survival rates were 83%, 77%, and 59% for SM1, SM2, and SM3 cases, respectively. On univariable analysis, lymph node metastasis, depth of submucosal invasion (SM3 versus SM1/2), and tumor location (upper thoracic versus mid/lower thoracic) were poor prognostic factors for overall survival. Multivariable Cox regression analyses identified depth of submucosal invasion (hazard ratio 2.51, 95% confidence interval: 1.37 to 4.61) and tumor location (hazard ratio 2.43, 95% confidence interval: 1.18 to 4.63) as preoperative prognostic factors. Tumor location (upper thoracic) and infiltration (SM3) are the worse prognostic factors of submucosal esophageal squamous cell carcinoma, but lymph node metastasis is not a predictor of poorer prognosis.

Full Text Available The present study was undertaken to elucidate the effect of Perilla frutescens fixed oil on experimental esophagitis in albino rats. A group of rats (n=6, treated with control vehicle (0.9% NaCl in double distilled water, 3 mL/kg, i.p. and Perilla frutescens fixed oil (100% (1, 2, and 3 mL/kg, i.p., or pantoprazole (30 mg/kg, i.p., were subjected to pylorus and forestomach ligation. Animals were sacrificed after 6 h and evaluated for the gastric pH, volume of gastric juices, total acidity, esophagitis index and free acidity. Esophageal tissues were further subjected to estimations of TBARS, GSH, catalase, and SOD. Treatment with fixed oil significantly inhibited the gastric secretion, total acidity, and esophagitis index. The oil also helped to restore the altered levels of oxidative stress parameters to normal. The present study also makes evident the in vitro antihistaminic and anticholinergic activity of alpha linolenic acid (ALA (18 : 3, n−3 on isolated rat ileum preparation. The lipoxygenase inhibitory, histamine antagonistic, antisecretory (anticholinergic, and antioxidant activity of the oil was attributed for its efficacy in reflux esophagitis.

Purpose: Radiation-induced esophageal toxicity (RIET) is a dose-limiting toxicity in lung cancer patients receiving radiotherapy. Accumulating evidence indicates that DNA repair and the cytokine pathways play essential roles in radiation-induced diseases. Genetic polymorphisms of genes in these pathways may affect gene function and/or gene expression and lead to different treatment-related esophageal toxicity. Materials and methods: This study investigated the association of 21 polymorphisms in 14 genes, with the occurrence of ≥grade 2 acute RIET. Genotypes were analyzed among 213 stage III lung cancer patients receiving radiotherapy. Results: We used Cox proportional hazard model to examine the effects of genotypes on ≥grade 2 acute RIET risk and Kaplan-Meier estimator to compare effects of different genotypes on such risk. Multivariate analysis showed that CT or TT genotype of TGF-β1-509C/T polymorphism was associated with a significantly higher RIET risk (adjusted hazard ratio [HR] = 2.47; 95% confidence interval (CI) = 1.17-5.24; P = 0.018, or HR = 3.86; 95% CI = 1.50-9.92; P = 0.005), respectively, compared with the CC genotype. Moreover, Lys/Gln+Gln/Gln genotypes of XPD Lys751Gln polymorphism were also associated with a significantly decreased RIET risk (adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.030). Conclusions: This report, for the first time, examined the influence of inherited variation in the DNA repair and the cytokine pathways on RIET.

Full Text Available Abstract Background Esophago-gastroduodenal anastomosis with rats mimics the development of human Barrett's esophagus and esophageal adenocarcinoma by introducing mixed reflux of gastric and duodenal contents into the esophagus. However, use of this rat model for mechanistic and chemopreventive studies is limited due to lack of genetically modified rat strains. Therefore, a mouse model of esophageal adenocarcinoma is needed. Methods We performed reflux surgery on wild-type, p53A135V transgenic, and INK4a/Arf+/- mice of A/J strain. Some mice were also treated with omeprazole (1,400 ppm in diet, iron (50 mg/kg/m, i.p., or gastrectomy plus iron. Mouse esophagi were harvested at 20, 40 or 80 weeks after surgery for histopathological analysis. Results At week 20, we observed metaplasia in wild-type mice (5%, 1/20 and p53A135V mice (5.3%, 1/19. At week 40, metaplasia was found in wild-type mice (16.2%, 6/37, p53A135V mice (4.8%, 2/42, and wild-type mice also receiving gastrectomy and iron (6.7%, 1/15. Esophageal squamous cell carcinoma developed in INK4a/Arf+/- mice (7.1%, 1/14, and wild-type mice receiving gastrectomy and iron (21.4%, 3/14. Among 13 wild-type mice which were given iron from week 40 to 80, twelve (92.3% developed squamous cell carcinoma at week 80. None of these mice developed esophageal adenocarcinoma. Conclusion Surgically induced gastroesophageal reflux produced esophageal squamous cell carcinoma, but not esophageal adenocarcinoma, in mice. Dominant negative p53 mutation, heterozygous loss of INK4a/Arf, antacid treatment, iron supplementation, or gastrectomy failed to promote esophageal adenocarcinoma in these mice. Further studies are needed in order to develop a mouse model of esophageal adenocarcinoma.

The treatment of achalasia is palliative. Pneumatic dilatation (PD) or laparoscopic Heller myotomy (LHM) just eliminates the outflow obstruction allowing easier emptying of the esophagus. The aim of this study was to evaluate the results of a multidisciplinary approach to esophageal achalasia. A consecutive series of patients with achalasia treated by a multidisciplinary esophageal team consisting of radiologists, gastroenterologists, and surgeons in a quaternary care center between May 2008 and April 2015 were analyzed. A total of 147 patients with achalasia underwent LHM and partial fundoplication. Sixty-two patients (42%) had been treated preoperatively with PD and/or botulinum toxin (BT). The preoperative Eckardt score (ES) was 6.4 ± 2. At a median follow-up of 22 months, 128 patients (87%) did well and required no further treatment (ES 0.1). The remaining 19 patients (13%) had recurrence of symptoms and required further treatment: 12 were treated with PD and improved (ES 0.7); 4 were treated with PD and BT and improved (ES 1.3); 3 failed PD. These 3 patients had been treated with multiple sessions of PD and BT before the myotomy. Overall, 144 patients (98%) did well with laparoscopic (87%) or laparoscopic and endoscopic treatment (11%). The results of this study show that (a) LHM is an effective treatment modality, (b) PD improved symptoms in the majority of patients with recurrent dysphagia after myotomy and (c) multiple preoperative endoscopic treatments seem to affect outcomes of LHM. Patients with achalasia should be treated in a quaternary care center by a multidisciplinary team.

Purpose: To overcome radiation resistance in esophageal adenocarcinoma by tumor-specific apoptotic gene targeting using tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Methods and Materials: Adenoviral vector Ad/TRAIL-F/RGD with a tumor-specific human telomerase reverse transcription promoter was used to transfer TRAIL gene to human esophageal adenocarcinoma and normal human lung fibroblastic cells (NHLF). Activation of apoptosis was analyzed by Western blot, fluorescent activated cell sorting, and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate labeling (TUNEL) assay. A human esophageal adenocarcinoma mouse model was treated with intratumoral injections of Ad/TRAIL-F/RGD plus local radiotherapy. Results: The combination of Ad/TRAIL-F/RGD and radiotherapy increased the cell-killing effect in all esophageal adenocarcinoma cell lines but not in NHLF cells. This combination also significantly reduced clonogenic formation (p < 0.05) and increased sub-G1 deoxyribonucleic acid accumulation in cancer cells (p < 0.05). Activation of apoptosis by Ad/TRAIL-F/RGD plus radiotherapy was demonstrated by activation of caspase-9, caspase-8, and caspase-3 and cleaved poly (adenosine diphosphate-ribose) polymerase in vitro and TUNEL assay in vivo. Combined Ad/TRAIL-F/RGD and radiotherapy dramatically inhibited tumor growth and prolonged mean survival in the esophageal adenocarcinoma model to 31.6 days from 16.7 days for radiotherapy alone and 21.5 days for Ad/TRAIL-F/RGD alone (p < 0.05). Conclusions: The combination of tumor-specific TRAIL gene targeting and radiotherapy enhances the effect of suppressing esophageal adenocarcinoma growth and prolonging survival

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.

Purpose: We have previously found that {<=} 75% of treatment failures after chemoradiotherapy for unresectable esophageal cancer appear within the gross tumor volume and that intensity-modulated (photon) radiotherapy (IMRT) might allow dose escalation to the tumor without increasing normal tissue toxicity. Proton therapy might allow additional dose escalation, with even lower normal tissue toxicity. In the present study, we compared the dosimetric parameters for photon IMRT with that for intensity-modulated proton therapy (IMPT) for unresectable, locally advanced, distal esophageal cancer. Patients and Methods: Four plans were created for each of 10 patients. IMPT was delivered using anteroposterior (AP)/posteroanterior beams, left posterior oblique/right posterior oblique (LPO/RPO) beams, or AP/LPO/RPO beams. IMRT was delivered with a concomitant boost to the gross tumor volume. The dose was 65.8 Gy to the gross tumor volume and 50.4 Gy to the planning target volume in 28 fractions. Results: Relative to IMRT, the IMPT (AP/posteroanterior) plan led to considerable reductions in the mean lung dose (3.18 vs. 8.27 Gy, p < .0001) and the percentage of lung volume receiving 5, 10, and 20 Gy (p {<=} .0006) but did not reduce the cardiac dose. The IMPT LPO/RPO plan also reduced the mean lung dose (4.9 Gy vs. 8.2 Gy, p < .001), the heart dose (mean cardiac dose and percentage of the cardiac volume receiving 10, 20, and 30 Gy, p {<=} .02), and the liver dose (mean hepatic dose 5 Gy vs. 14.9 Gy, p < .0001). The IMPT AP/LPO/RPO plan led to considerable reductions in the dose to the lung (p {<=} .005), heart (p {<=} .003), and liver (p {<=} .04). Conclusions: Compared with IMRT, IMPT for distal esophageal cancer lowered the dose to the heart, lung, and liver. The AP/LPO/RPO beam arrangement was optimal for sparing all three organs. The dosimetric benefits of protons will need to be tailored to each patient according to their specific cardiac and pulmonary risks. IMPT for

From September 1987-December 1989, 36 patients with advanced esophageal cancer entered a study in order to determine the efficacy of palliation by a single session of intraluminal irradiation. A dose of 15 Gy was administered at 1 cm distance from the central axis of the applicator. In 22 of 32 patients alive at least 6 weeks after treatment dysphagia improved, in 14 this relief was complete. Re-obstruction occurred in 8 of the 36 patients. Intraluminal irradiation is easy to administer and safe, it forms a useful addition to the therapeutic possibilities for the palliation of esophageal cancer. (author). 12 refs., 2 figs., 1 tab.

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, pesophageal 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).

From November 1, 1992 to January 31, 1997, 227 patients with inoperable esophageal and cardial carcinomas were treated with Nd:YAG laser therapy and prosthesis intubation. The retrograde technique was used in most cases. The tumor involved in 75 pts the Cardia, in 65 the middle thoracic esophagus, in 47 pts the lower thoracic esophagus, in 23 in the upper thoracic esophagus and in 17 in the cervical esophagus. The indications for palliative Nd:YAG laser and prosthesis intubation were a locally advanced or metastatic tumor in 146 pts (64.4%) and poor surgical risk in 81 pts (35.6%). The quality of palliation was evaluated according to the ability to swallow. The mean survival rate of the patients during the follow up was 22 weeks for the laser therapy and 16 weeks for the prosthesis intubation.

Full Text Available Esophageal cancer is one of the most common malignancies in our country. Patients often seek medical advice in advanced and inoperable stages or with cervical esophageal cancer, in which operation is accompanied by sever morbidity. In this conditions many of them cannot tolerate chemo-radiation, or refuse it. Therefore radiotherapy is applied as a single modality in palliation of many patients with esophageal cancer. One of the palliative radio therapeutic methods is application of 5000 CGY in 20 fractions (Long Course; but considering the great number of our patients and limited capacity of radiotherapy centers, as well as emphasis of literature on palliation with 4000 CGY in 13 fractions (short course, we decided to compare these two methods (which are both used in our departments. In this retrospective analytic study, the files of 283 patients with esophageal cancer referred to cancer institute of Imam Khomeini Hospital from 1989-1999 were studied. Patients were between 27-97 years old (mean age=58.3 and most of them were male (53.7 percent. The mean length of lesion was 8.5 cm. The most common site of lesion was middle third at esophagus (48.1 percent and the most common pathology was squamous cell carcinoma (99.6 percent. Fifty-four percent of patients were hot tea drinkers habitually. From the mentioned variables, only length of lesion had significant relationship with overall survival (P=0.04. Thirty-eight of 283 patients were excluded from analytic study because of incomplete follow-up. The number of patients had been treated by long course (5000 CGY in 20 fractions was 137 and the remainder (108 patients by short course (4000 CGY in 13 fractions. No significant difference was seen statistically between these two groups in overall and dysphagia-free survival (Kaplan-Meyer test. Also total dosage of spinal cord is lower in the short course. Thus regarding to less required time in short course and comparable palliation and survival between

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

Full Text Available The stratified squamous epithelium of the esophagus shows a proliferative basal layer of keratinocytes that undergo terminal differentiation in overlying suprabasal layers. Esophageal pathologies, including eosinophilic esophagitis, gastroesophageal reflux disease, Barrett's esophagus, squamous cell carcinoma, and adenocarcinoma, cause perturbations in the esophageal epithelial proliferation-differentiation gradient. Three-dimensional (3D culture platforms mimicking in vivo esophageal epithelial tissue architecture ex vivo have emerged as powerful experimental tools for the investigation of esophageal biology in the context of homeostasis and pathology. Herein, we describe types of 3D culture that are used to model the esophagus, including organotypic, organoid, and spheroid culture systems. We discuss the development and optimization of various esophageal 3D culture models; highlight the applications, strengths, and limitations of each method; and summarize how these models have been used to evaluate the esophagus under homeostatic conditions as well as under the duress of inflammation and precancerous/cancerous conditions. Finally, we present future perspectives regarding the use of esophageal 3D models in basic science research as well as translational studies with the potential for personalized medicine.

For recurrent esophageal cancer after primary definitive radiotherapy, no general treatment guidelines are available. We evaluated the toxicities and clinical outcomes of re-irradiation (re-RT) for recurrent esophageal cancer. We analyzed 10 patients with recurrent esophageal cancer treated with re-RT after primary definitive radiotherapy. The median time interval between primary radiotherapy and re-RT was 15.6 months (range, 4.8 to 36.4 months). The total dose of primary radiotherapy was a median of 50.4 Gy (range, 50.4 to 63.0 Gy). The total dose of re-RT was a median of 46.5 Gy (range, 44.0 to 50.4 Gy). The median follow-up period was 4.9 months (range, 2.6 to 11.4 months). The tumor response at 3 months after the end of re-RT was complete response (n = 2), partial response (n = 1), stable disease (n = 2), and progressive disease (n = 5). Grade 5 tracheoesophageal fistula developed in three patients. The time interval between primary radiotherapy and re-RT was less than 12 months in two of these three patients. Late toxicities included grade 1 dysphagia (n = 1). Re-RT of recurrent esophageal cancer after primary radiotherapy can cause severe toxicity.

Pericardial effusion is an important late toxicity after concurrent chemoradiotherapy (CCRT) for locally advanced esophageal cancer. We investigated the clinical and dosimetric factors that were related to pericardial effusion among patients with thoracic esophageal cancer who were treated with definitive CCRT using the two opposed fields technique (TFT) or the four-field technique (FFT), as well as the effectiveness of FFT. During 2007-2015, 169 patients with middle and/or lower thoracic esophageal cancer received definitive CCRT, and 94 patients were evaluable (51 FFT cases and 43 TFT cases). Pericardial effusion was observed in 74 patients (79%) and appeared at 1-18.5 months (median: 5.25 months) after CCRT. The 1-year incidences of pericardial effusions were 73.2% and 76.7% in the FFT and TFT groups, respectively (P = 0.6395). The mean doses to the pericardium were 28.6 Gy and 31.8 Gy in the FFT and TFT groups, respectively (P = 0.0259), and the V40 Gy proportions were 33.5% and 48.2% in the FFT and TFT groups, respectively (P effusion was not observed in patients with a pericardial V40 Gy of effusion after CCRT were similar in both groups. As symptomatic pericardial effusion was not observed in patients with a pericardial V40 Gy of effusion.

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 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 HIV-infected patients. However, heartburn and acid regurgitation were independently (P symptom scores were reliable in both HIV (α, 0.86) and non-HIV-infected patients

Functional Esophageal Disorders.

Science.gov (United States)

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.

To evaluate and discuss all the potential complications affecting morbidity of patients treated with surgery for primary achalasia. A review of the available English literature published to date has been conducted. All articles reporting surgical experience in achalasia were examined and then were selected only those specifically inherent to the topic at issue. Mucosal perforation is the main intra-operative complication while persistence or recurrence of the disease and gastro-esophageal reflux are those mostly affecting patients afterwards, even at long-term follow-up. A few other less common morbidities, as well as the technical considerations useful to minimize and manage each complication mentioned, are reported. Minimally invasive surgery for achalasia consent to treat patients with a low rate of perioperative complications that can be managed with conservative approach in the majority of cases. Risk of esophageal cancer exists in these patients and remains although surgical therapy. Laparoscopic Heller myotomy along with partial fundoplication is a safe and effective procedure that should be considered as the treatment of choice at first evaluation of achalasic patients rather than endoscopic techniques. Robotic technology may add further contribution in diminishing perioperative complications.

This prospective study aimed to evaluate the feasibility and safety of locoregional mitomycin C (MMC) injection to treat refractory esophageal strictures after endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. Patients with dysphagia and strictures that were refractory to repeated endoscopic balloon dilation (EBD) were eligible. After EBD, MMC was injected into the dilated site. Between June 2009 and August 2010, five patients were recruited. The treatment was performed once in two patients and twice in three patients with recurrent dysphagia or restenosis. In all patients, passing a standard endoscope through the site was easy and the dysphagia grade improved (grade 3→1 in 3 patients, grade 4→2 in 2 patients). No serious complications were noted. During the observation period of 4.8 months, neither recurrent dysphagia nor re-stricture appeared in any of the patients. The combination of locoregional MMC injections and EBD is feasible and safe for the treatment of esophageal strictures after ESD.Recently, endoscopic submucosal dissection (ESD) has been developed and accepted as a new endoscopic treatment for gastrointestinal tumors. ESD is a promising treatment for superficial esophageal carcinoma (SEC), and it has a reliable en bloc resection rate. However, the application of ESD for widespread lesions is challenging because of the high risk of the development of severe strictures, which lead to a low quality of life after ESD. Although endoscopic balloon dilation (EBD) is effective for benign strictures, it needs to be performed frequently until the dysphagia disappears 1. Mitomycin C (MMC), which is a chemotherapeutic agent derived from some Streptomyces species 2, reduces scar formation when topically applied to a surgical lesion. MMC has been applied to treat strictures in a variety of anatomical locations, including a variety of organs 3. The aim of this study was to prospectively evaluate both the feasibility and the safety of

According to the Guidelines for Diagnosis and Treatment of Carcinoma of the Esophagus in Japan, the standard treatment of esophageal cancer with cStage II / III is preoperative chemotherapy and radical resection. But when the tumor has deep ulcer, the perforation of it is sometimes occurred due of the anti-tumor effect and we are forced to change the standard treatment. In this time, we report a case of emergency resection of esophageal cancer which is on the brink of perforation after neoadjuvant chemotherapy. A 62-year-old woman had locally advanced esophageal cancer(cT4N2M0)and performed neoadjuvant chemotherapy(NAC). After 2 courses of NAC, the patient got into critical condition that the esophageal cancer was on the brink of perforation, thus we immediately performed emergency resection of the tumor. Unfortunately, the tumor was not completely resected because of invasion to the Botallo ligament, but we were able to avoid a critical state such as mediastinitis or penetration to the aorta. In multimodality therapy for locally advanced tumor, immediate response to oncologic emergency is significantly required, impacting on the prognosis and quality of life.

A prospective radiologic-endoscopic study of the esophagogastric region in 266 patients, including 206 normals and 60 with esophagitis, is reported. The endoscopic classification grading severity of esophagitis was grade 1-normal; grades 2. 3. and 4-mild, moderate, and severe esophagitis, respectively. Radiology detected 22% of patient with mild esophagitis, 83% with moderate esophagitis, and 95% with severe esophagitis. Although hiatal hernia was present in 40% of normals and 89% with esophagitis, absence of radiographic hiatal hernia excluded esophagitis with 95% accuracy. The implications of this study regarding the role of radiology in evaluating patient with suspected reflux esophagitis are discussed. (orig.) [de

DDEC: Dragon database of genes implicated in esophageal cancer

KAUST Repository

Essack, Magbubah

2009-07-06

Background: Esophageal cancer ranks eighth in order of cancer occurrence. Its lethality primarily stems from inability to detect the disease during the early organ-confined stage and the lack of effective therapies for advanced-stage disease. Moreover, the understanding of molecular processes involved in esophageal cancer is not complete, hampering the development of efficient diagnostics and therapy. Efforts made by the scientific community to improve the survival rate of esophageal cancer have resulted in a wealth of scattered information that is difficult to find and not easily amendable to data-mining. To reduce this gap and to complement available cancer related bioinformatic resources, we have developed a comprehensive database (Dragon Database of Genes Implicated in Esophageal Cancer) with esophageal cancer related information, as an integrated knowledge database aimed at representing a gateway to esophageal cancer related data. Description: Manually curated 529 genes differentially expressed in EC are contained in the database. We extracted and analyzed the promoter regions of these genes and complemented gene-related information with transcription factors that potentially control them. We further, precompiled text-mined and data-mined reports about each of these genes to allow for easy exploration of information about associations of EC-implicated genes with other human genes and proteins, metabolites and enzymes, toxins, chemicals with pharmacological effects, disease concepts and human anatomy. The resulting database, DDEC, has a useful feature to display potential associations that are rarely reported and thus difficult to identify. Moreover, DDEC enables inspection of potentially new \\'association hypotheses\\' generated based on the precompiled reports. Conclusion: We hope that this resource will serve as a useful complement to the existing public resources and as a good starting point for researchers and physicians interested in EC genetics. DDEC is

Between 1983 and 1986, 35 of 90 patients with acquired immunodeficiency syndrome (AIDS) had double-contrast esophagograms to rule out opportunistic esophagitis. The radiographs were reviewed without knowledge of the clinical or endoscopic findings. Candida esophagitis was diagnosed radiographically in 17 patients who had varying degrees of plaque formation and viral esophagitis in three who had discrete ulcers without plaques. All three patients with viral esophagitis (herpes in 2 and cytomegalo virus in one) and 15 of 17 with Candida esophagitis had endoscopic and/or clinical corroboration of the radiographic diagnosis. Thus, the authors' experience suggests that fungal and viral esophagitis can often be differentiated on double-contrast esophagography, so that appropriate antifungal or antiviral therapy can be instituted without need for endoscopic intervention

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 aim of this study was to analyze the risk factors and prognosis for patients with esophageal perforation occurring during or after radiotherapy for esophageal carcinoma. We retrospectively analyzed 322 patients with esophageal carcinoma. These patients received radiotherapy for unresectable esophageal tumors, residual tumors after operation, or local recurrence. Of these, 12 had radiotherapy to the esophagus before being admitted, 68 patients had concurrent chemoradiotherapy (CRT), and 18 patients had esophageal perforation after RT (5.8%). Covered self-expandable metallic stents were placed in 11 patients. Two patients continued RT after stenting and control of infection; one of these suffered a new perforation, and the other had a massive hemorrhage. The median overall survival was 2 months (0-3 months) compared with 17 months in the non-perforation group. In univariate analysis, the Karnofsky performance status (KPS) being ≤ 70, age younger than 60, T4 stage, a second course of radiotherapy to the esophagus, extracapsular lymph nodes (LN) involving the esophagus, a total dose > 100 Gy (biologically effective dose -10 ), and CRT were risk factors for perforation. In multivariate analysis, age younger than 60, extracapsular LN involving the esophagus, T4 stage, and a second course of radiotherapy to the esophagus were risk factors. In conclusion, patients with T4 stage, extracapsular LN involving the esophagus, and those receiving a second course of RT should be given particular care to avoid perforation. The prognosis after perforation was poor. (author)

Radiologic and manometric findings were correlated in 17 patients with diffuse esophageal spasm (DES). All patients initially had chest pain and/or dysphagia and had a manometric diagnosis of DES. Mean percentage of normal peristalsis manometrically was 46% (range, 20%-80%). Based on radiologic examination, an esophageal motor disorder consistent with DES was diagnosed in 12 of 17 patients, and there was one misinterpretation of achalasia. Radiologic detection was not related significantly to the percentage of peristalsis seen on manometric examination. Mean esophageal wall thickness as measured radiographically in patients with DES was 2.6 mm, compared with 2.5 mm in 17 individuals with normal results of manometry

Esophagoscintigraphy with labelled liquid and solid food was performed in 34 patients disease of the esophagus in the patient history permitting the determination of quantitative and qualitive characteristics of normal motor-evacuatory function of the esophagus and lower esophageal sphincter (LES). A total of 46 patients with esophageal cancer and stomach cancer with the envolvement of the esophagus before treatment were examined. In cancer of the esophagus its function depended on a tumor site and stage. In order to raise diagnostic sensitivity dynamic esophagoscintigraphy should be performed using liquid and solid food because during liquid passage a study with a hard bolus of patients with severe esophageal disfunction showed that in 36.9% of the patients the quantitative and qualitative indices were within normal. Radionuclide methods permit the determination of the level of a pathological focus, a degree of esophageal permeability, quantitative characterization of a degree of disorder of esophageal function in order to raise the functional diagnosis of the esophaeous and LES, and the determination of motor disorders at the earliest stages of tumor development

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.

To describe our experience in treating esophageal and pharyngeal perforation after anterior cervical spine surgery. Six patients with esophageal injury and one patient with pharyngeal injury after anterior cervical spinal surgery, managed at our department between 2000 and 2015, were analyzed retrospectively. During the study period, 7 patients (6 male and 1 female; mean age, 45 years) presented with esophageal perforation. The original anterior cervical spinal surgery was performed due to trauma in 2 patients and because of a degenerative cervical disorder in 5. Early esophageal perforation was diagnosed in 2 patients, and delayed esophageal injury due to chronic irritation with the cervical implants was noted in 5. Three of the five delayed perforation cases were related to cervical instrument displacement. Two patients showed no definite signs of infection, whereas 5 patients had various symptoms, including fever, neck pain, odynophagia, neck swelling, and upper extremity weakness. Two patients with a large defect underwent surgical repair and three with minimal perforation due to chronic irritation from the implants underwent instrument removal without direct repair of defect. Two asymptomatic patients received no intervention. Six patients with infection completely recovered from esophageal injury after treatment for a mean duration of 5.2 weeks (range, 4-8 weeks). One patient died because of postoperative pneumonia and sepsis after implant removal. Esophageal and pharyngeal injury after cervical spinal surgery may occur either directly due to spinal trauma and vigorous intraoperative retraction or due to chronic irritation with cervical implants. In cases of perforation associated with infection, various surgical modalities, including primary closure and reinforcement with a flap, could be considered depending on factors such as esophageal defect size, infection severity, and timing of recognition of injury.

We reviewed our clinical experiences of chemoradiotherapy (CRT) for esophageal cancer (EC) in 44 patients with multiple primary malignant neoplasms. Among them, 34 were accompanied with synchronous tumors, 8 were accompanied with antecedent tumors and 8 with subsequent tumors. The sites of primary malignant neoplasms were as follows; stomach 24 (43.6%), head and neck 17 (30.9%), colon and rectum 4 (7.3%). Among the 19 patients with synchronous cancer in the stomach, 6 patients underwent gastrectomy or endoscopic mucosal resection before CRT, and the others received definitive CRT as initial treatment. While 5 patients were alive without recurrence of EC and gastric cancer, more than half of the patients died of EC. Among 11 patients with head and neck cancer (HNC), 9 patients underwent surgery for HNC before CRT, because the clinical stages of the HNC was more progressive than that of EC. Only 3 patients achieved complete cure of both EC and HNC. The number of patients who developed subsequent tumors after CRT for EC was too small for us to draw definitive conclusions from our discussion, so further long-term follow-up and analysis based on large-scale surveys are required. Although CRT has become one of the standard treatments for EC, there is no treatment strategy for patients with both EC and other malignant primary neoplasms. Our results suggest that we should consider the curability of EC by CRT when we treat such patients. (author)

Esophageal cancer has been reported as the ninth most common malignancy and ranks as the sixth most frequent cause of death worldwide. Esophageal cancer treatment involves surgery, chemotherapy, radiation therapy, or combination therapy. Novel strategies are needed to boost the oncologic outcome. Recent advances in the molecular biology of esophageal cancer have documented the role of genetic alterations in tumorigenesis. Oncogenes serve a pivotal function in tumorigenesis. Targeted therapies are directed at the unique molecular signature of cancer cells for enhanced efficacy with low toxicity. RNA interference (RNAi) technology is a powerful tool for silencing endogenous or exogenous genes in mammalian cells. Related results have shown that targeting oncogenes with siRNAs, specifically the mRNA, effectively reduces tumor cell proliferation and induces apoptotic cell death. This article will briefly review studies on silencing tumor enhancer genes related to the induction of esophageal cancer

Total laryngectomee requires some form of alaryngeal speech for communication. Generally, esophageal speech is regarded as the most available and comfortable technique for alaryngeal speech. But esophageal speech is difficult to train, so many patients are unable to attain esophageal speech for communication. To understand mechanism of esophageal of esophageal speech on total laryngectomee, evaluation of anatomical change of the pharyngoesophageal segment is very important. We used video fluoroscopy for evaluation of pharyngesophageal segment during esophageal speech. Eighteen total laryngectomees were evaluated with video fluoroscopy from Dec. 1986 to May 1987 at Y.U.M.C. Our results were as follows: 1. Peseudoglottis is the most important factor for esophageal speech, which is visualized in 7 cases among 8 cases of excellent esophageal speech group. 2. Two cases of longer A-P diameter at the pseudoglottis have the best quality of esophageal speech than others. 3. Two cases of mucosal vibration at the pharyngoesophageal segment can make excellent esophageal speech. 4. The cases of failed esophageal speech are poor aerophagia in 6 cases, abscence of pseudoglottis in 4 cases and poor air ejection in 3 cases. 5. Aerophagia synchronizes with diaphragmatic motion in 8 cases of excellent esophageal speech.

Gastro-Esophageal Reflux in Children

Full Text Available 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.

2017-12-01

Full Text Available Esophageal diverticula in the pediatric population are rare. The etiologies and presentations can vary widely which can make it difficult to diagnose without imaging or direct visualization. We are reporting a case of a 14-year-old male with history of asthma, anorexia, weight loss, and chest discomfort. CXR findings of mediastinal widening prompted a more extensive evaluation. He was found to have two esophageal diverticula, phlegmonous changes, and osteomyelitis of the T5 and T6 vertebra. He was initially treated with IV antibiotic therapy, bypassing the affected area with nasogastric enteric tube feedings, and a cervical thoracic orthosis brace for spine stability. He regained his lost weight and became asymptomatic, returning to a regular diet. The family has declined to pursue surgical intervention at present.

Recent developments in esophageal motor disorders.

Beaumont, Hanneke; Boeckxstaens, Guy

2007-07-01

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.

Laparoscopic Heller myotomy combined with anterior (Dor) fundoplication is the most widely-used surgical procedure for treating esophageal achalasia in Europe From November 1992 through May 2010 we performed laparoscopic Heller-Dor on 173 patients Conversion to laparotomy was required in three cases (1.7%) at the beginning of the experience (for mucosal) perforation which was the most frequent intraoperative complication, managed laparoscopically with the increasing experience. Five (2.9%) cases had minor postoperative complications. Clinical results were satisfactory in 99.4% of cases. One patient (0.6%) had severe persistent dysphagia. Mean esophageal diameter decreased from 50 mm ± 12 (range 20- 90) to 25 mm ± 7 (range 15-80). Lower esophageal sphincter pressure decreased from 32 mmHg (median, range 10- 93) pre-operatively to 11 mmHg (median, range 5-21) at one year follow up and residual pressure from 12 mmHg (median, range 3-30) to 4 mmHg (median, range 1-8). Impedance and pH monitoring showed normal levels in 39/47 (83%) patients who agreed to testing. The good outcomes of this experience, in part due to careful adherence to technical aspects of the operation, confirm that the laparoscopic Heller-Dor is the gold standard surgical treatment for esophageal achalasia.

Full Text Available BACKGROUND Esophageal achalasia (EA is a primary esophageal motility disorder of unclear aetiology. Standard treatments of EA are: pneumatic balloon dilation (PBD of the lower esophageal sphyncter (LES and surgical cleaving of the muscle by Heller myotomy. Although the treatment effectively cures dysphagia, the symptoms recur in about a half of the patients. Our point of interest was long-term effectiveness of EA treatment at our department. METHODSWe made a retrospective analysis of EA patients treated at our department of thoracic surgery during the 2000–2010 period.RESULTSIn 11 years we performed 187 PBD and 22 laparoscopic myotomies (LM in 148 patients. Three years after the procedure 65 % of patients after PBD and 90 % of patients after LM showed no signs of disease. The risk of recurrence was 3.56-times greater (p = 0.03 after PBD (in comparison to LM, whereas patients older than 50 years bear 0.51-times lower risk (p = 0.02. The most significant complicatios were esophageal perforation in 3 patients (1.6 % after PBD and gastroesophageal reflux in 3 patients (15 % after LM.CONCLUSIONSPBD is a fast, simple, inexpensive and very efficient method of EA treatment, which can be safely performed in almost every patient. LM is far more expensive and a more complicated method that is more suitable for younger patients, in whom PBD is less effective.

2003-01-01

Congenital H-type and recurrent tracheo-esophageal fistulas (TEF) are always difficult to diagnose. For a more accurate diagnosis we designed a new double balloon catheter, which is a modification of esophageal dilatation balloon. The catheter has two balloons to occlude the esophagus proximal and distal to the fistula. The fistula can be identified by passing of the contrast material to the tracheal tree, which was injected into the esophageal segment between the inflated balloons. To prove the efficiency of this catheter, a TEF was created surgically in a New Zealand rabbit. On the postoperative fourteenth day the catheter was tried and the fistula could be visualized easily by injecting the contrast material. We think this technique may be of use in the diagnosis of TEF in children. (orig.)

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

To investigate the treatment outcome and failure patterns after definitive chemoradiation therapy in locally advanced, unresectable esophageal cancer. Materials and Methods: From February 1994 to December 2002, 168 patients with locally advanced unresectable or medically inoperable esophageal cancer were treated by definitive chemoradiation therapy. External beam radiation therapy (EBRT) (42-46 Gy) was delivered to the region encompassing the primary tumor and involved lymph nodes, while the supraclavicular fossa and celiac area were included in the treatment area as a function of disease location. The administered cone-down radiation dose to the gross tumor went up to 54-66 Gy, while the fraction size of the EBRT was 1.8-2.0 Gy/fraction qd or 1.2 Gy/fraction bid. An optional high dose rate (HDR) intraluminal brachytherapy (BT) boost was also administered (Ir-192, 9-12 Gy/3 -4 fx). Two cycles of concurrent FP chemotherapy (5-FU 1,000 mg/m2/day, days 2-6, 30-34, cisplatin 60 mg/m2/day, days 1, 29) were delivered during radiotherapy with the addition of two more cycles. Results: One hundred sixty patients were analyzable for this review [median follow-up time: 10 months (range 1-149 months)]. The number of patients within AJCC stages I, II, III, and IV was 5 (3.1%), 38 (23.8%), 68 (42.5%), and 49 (30.6%), respectively. A HDR intraluminal BT was performed in 26 patients. The 160 patients had a median EBRT radiation dose of 59.4 Gy (range 44.4-66) and a total radiation dose, including BT, of 60 Gy (range 44.4-72), while 144 patients received a dose higher than 40 Gy. Despite the treatment, the disease recurrence rate was 101/160 (63.1%). Of these, the patterns of recurrence were local in 20 patients (12.5%), persistent disease and local progression in 61 (38.1%), distant metastasis in 15 (9.4%), and concomitant local and distant failure in 5 (3.1%). The overall survival rate was 31.8% at 2 years and 14.2% at 5 years (median 11.1 months). Disease-free survival was 29

To compare the long-term results of total and partial fundoplication on esophagus myotomy. From January 1978 to October 1998, 64 patients with achalasia or diffuse esophageal spasm underwent esophagomyotomy and antireflux operation via left thoracotomy. Twenty-one patients underwent Nissen total fundoplication (Nissen group) and 43 patients underwent Belsey Marker IV partial fundoplication (Belsey group). Clinical, radiologic, radionuclide transit, manometric, 24-hour pH monitoring and endoscopic assessments were performed before and after the operation. There was no operative death and major complications for either group. At over 6 years follow-up and compared to Belsey group, patients in Nissen group revealed a higher frequency of dysphagia (P = 0.025) and more radionuclide material retention (P = 0.044). Both operative procedures reduced the lower esophageal sphincter pressure gradient. However, in Nissen group, the esophageal diameter observed on radiology was significantly increased from 3.9 cm preoperatively to 5.5 cm postoperatively (P = 0.012), while it kept the same for Belsey group (from 5.4 to 5.3 cm, P = 0.695). Reoperation in order to relieve the recurrent dysphagia and esophageal obstruction was performed on 8 patients in Nissen group and 1 in Belsey group (P < 0.01). When treating achalasia or diffuse esophageal spasm by esophageal myotomy and an antireflux operation, a total fundoplication is not appropriate, whereas a partial fundoplication provides proper antireflux effect without significant esophageal emptying difficulty.

The aim of this study was to investigate the effectiveness of hyaluronic acid on the prevention of esophageal damage and stricture formation after experimental caustic (alkaline) esophageal injury in rats. Twenty-one Wistar albino rats were randomly divided into three groups. A caustic esophageal burn was created following the Gehanno model: Group l (n=7) underwent operation, but no injury; Group 2 (n=7) was injured and left untreated; and Group 3 (n=7) was injured and treated with hyaluronic acid, first topically and then orally by gavage (2×0.3mL; 12.5mg/mL for 7days). The caustic esophageal burn was created by instilling 25% NaOH into the distal esophagus. All rats were euthanized on day 22 for evaluation. The efficacy of hyaluronic acid treatment was assessed histopathologically and biochemically via blood determination of the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and sulfhydryl group (SH) and lipid hydroperoxidase (LOOH) levels. Statistical analyses were performed. Weight gain was significantly lower in Group 2 than in the other two groups (POSI, and SH and LOOH levels were higher in Group 2 than in the other two groups. The mean stenosis index, inflammation, TAS, SH and OSI in Group 2 were significantly different than those in the other two groups (P<0.05). Hyaluronic acid treatment is effective in treating damage and preventing strictures after caustic esophageal burn in rats. Copyright © 2013 Elsevier Inc. All rights reserved.

Full Text Available 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.

Esophageal resection is a traumatic intervention usually performed on patients with poor condition, resulting high mortality and morbidity. To improve the high incidence of complications, minimal invasive interventions were introduced. The results of the thoracoscopically and laparoscopically performed esophageal resection (McKeown) was investigated after 20 cases and the technical details of the surgical intervention are presented. 20 thoracoscopic esophageal resection with laparoscopic gastric tube formation (sec. Akiyama) preparing the esophago-gastric anastomosis on the neck were performed in our department in the last four years. 1 patient with stricture and the other 19 patients with esophageal cancer were operated on, among them11 had T4 stage. 17 patient received neoadjuvant chemo-radiotherapy because of advanced disease. Regular follow up examinations were performed in the oncological outpatient department. 8 patients are alive after a mean follow up period of 25 months, 2 of them are treated oncologically because of recurrent disease. 19 patients were extubated within 12 hours after the intervention and the time spent in the intensive care unit were reduced to 1 or 2 days. The mean duration of the intervention was 320 minutes. Thoracoscopic dissection was performed in 8 patients without ventilation of the right lung using double lumen tracheal tube, among them 3 patients developed pneumonia in the postoperative period. The remaining 12 patients were operated with ventilated right lung, among them one patient developed pneumonia. One patient was converted because of injury of the thoracic aorta, after urgent thoracotomy we managed to suture the aortic wall. 1 patient died in 30 days after the operation, caused by leakage of the anastomosis, resulting mediastinitis and esophago-tracheal fistula. In two patients re-thoracoscopy and ligation of the thoracic duct was performed because of chylothorax refractory for conservative treatment. According to our

2017-01-01

Pneumatic dilatation and Heller myotomy have been thoroughly studied as the most viable treatment options for achalasia. The pendulum, however, is shifting to the minimally invasive approach. Since Inoue et al. published the experience of the first 17 cases of peroral endoscopic myotomy (POEM) in 2010, there have been at least 5,000 cases performed worldwide and the number is increasing exponentially. Experts across the globe have been extending the indications to various esophageal motility disorders, to patients of extremes of age, sigmoidal esophagus and re-operated patients. There are a few variations in technique across different centers in defining the gastroesophageal junction (GEJ) and adequacy of myotomy, the optimal length, site of myotomy and whether the full thickness of the muscle wall should be cut. Large case series demonstrated its promising efficacy & reasonable complication profile. Randomized controlled trial in comparison with the gold standard, Heller myotomy, is ongoing. The future application of submucosal tunnelling technique is thrilling with its extension in tumour resection, antropyloromyotomy and other natural orifice transluminal endoscopic surgery (NOTES).

Purpose: To use pretreatment megavoltage computed tomography (MVCT) scans to evaluate setup variations in anterior-posterior (AP), lateral, and superior-inferior (SI) directions and rotational variations, including pitch, roll, and yaw, for esophageal cancer patients treated with helical tomotherapy. Methods and Materials: Ten patients with locally advanced esophageal cancer treated by combined chemoradiation using helical tomotherapy were selected. After patients were positioned using their skin tattoos/marks, MVCT scans were performed before every treatment and automatically registered to planning kilovoltage CT scans according to bony landmarks. Image registration data were used to adjust patient setups before treatment. A total of 250 MVCT scans were analyzed. Correlations between setup variations and body habitus, including height, weight, relative weight change, body surface area, and patient age, were evaluated. Results: The standard deviations for systematic setup corrections in AP, lateral, and SI directions and pitch, roll, and yaw rotations were 1.5, 3.7, and 4.8 mm and 0.5 deg., 1.2 deg., and 0.8 deg., respectively. The appropriate averages of random setup variations in AP, lateral, and SI directions and pitch, roll, and yaw rotations were 2.9, 5.2, and 4.4 mm, and 1.0 deg., 1.2 deg., and 1.1 deg., respectively. Setup variations were stable throughout the entire course of radiotherapy in all three translational and three rotational displacements, with little change in magnitude. No significant correlations were found between setup variations and body habitus variables. Conclusions: Daily MVCT scans before each treatment can effectively detect setup errors and thereby reduce planning target volume (PTV) margins. This will reduce radiation dose to critical organs and may translate into lower treatment-related toxicities

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; PCLT than with EPT (OR: 3.4; 2.4-5.0; PCLT among our selected raters. On the basis of these findings, EPT may be the preferred assessment modality of esophageal motility.

A population-based case-control was performed to explore familial aggregation of esophageal squamous cell carcinoma (ESCC). Family history of cancer was assessed by a structured questionnaire, and from which 2 cohorts of relatives of cases and controls were reconstructed. Unconditional logistic regression and Cox proportional hazards regression were applied for case-control design and reconstructed cohort design, respectively. We observed a close to doubled risk of ESCC associated with a positive family history of esophageal cancer among first degree relatives (odds ratio [OR] = 1.85, 95% confidence interval [CI]: 1.42–2.41), after adjusting age, sex, family size and other confounders. The excess risks of ESCC increased with the increasing of first-degree relatives affected by esophageal cancer (p < 0.001). In particular, those individuals whose both parents with esophageal cancer had an 8-fold excess risk of ESCC (95% CI: 1.74–36.32). The reconstructed cohort analysis showed that the cumulative risk of esophageal cancer to age 75 was 12.2% in the first-degree relatives of cases and 7.0% in those of controls (hazard ratio = 1.91, 95% CI: 1.54–2.37). Our results suggest family history of esophageal cancer significantly increases the risk for ESCC. Future studies are needed to understand how the shared genetic susceptibility and/or environmental exposures contribute to the observed excess risk. PMID:26526791

Deglutitive inhibition, latency between swallow and esophageal contractions and primary esophageal motor disorders.

Sifrim, Daniel; Jafari, Jafar

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.

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 (Preflux events and increase exposure to gastric refluxate. © 2011 Blackwell Publishing Ltd.

A Unique Case of a Patient with Rectal Cancer Who Developed Benign Esophageal Stenosis after Localized Rectal Radiation and Systemic Chemotherapy

Full Text Available Acute esophagitis and esophageal strictures typically occur after local radiation therapy to the thoracic field. Toxicity is usually limited to the field of radiation and potentially augmented by concomitant use of chemotherapy, however esophageal stricturing due to chemotherapy alone is exceedingly rare. Gastrointestinal toxicity has been previously reported in the setting of 5-fluorouracil (5-FU-based chemotherapy with abnormal thymidylate synthase or dihydropyrimidine dehydrogenase activities. We present a unique case of isolated chemotherapy-induced esophageal stricture in the setting of stage IIIa rectal adenocarcinoma which presented shortly after initiation of treatment with 5-FU-based chemotherapy in a patient with normal thymidylate synthase and dihydropyrimidine dehydrogenase assays. These findings prompt further investigation of pathways and potential risk factors leading to esophageal toxicity in patients treated with 5-FU-based chemotherapy.

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 reflux groups. The correlation between IL-6 and MUC-3 was significant within the control and erosive reflux groups, and the correlation between MUC-1 and MUC-5AC was significant within the erosive reflux group. The results of this study suggest that the profile of mucin expression in the esophageal mucosa is influenced by the pH and composition of the gastro-esophageal reflux. Further work should explore the
