However, the use of tunnel endoscopy to diagnose adenocarcinoma of the esophagus originating from the submucosa has not been well studied.CASE SUMMARY A 74-year-old man who presented with dysphagia for half a year underwent a series of checks, such as gastroendoscopy, X-ray contrast examination of the upper digestive tract, endoscopic ultrasonography, high-resolution esophageal manometry, and positron emission computed tomography. It should be noted that the stenosis of the esophagus was too narrow for endoscopic ultrasoundguided fine needle aspiration. The cause remained undiagnosed. Eventually, the tunnel endoscopic technique was perform for the pathological examination in the submucosa and the final diagnosis was adenocarcinoma of the esophagus. The patient and family members chose expectant treatment due to the patient's age and the high costs of surgical treatment.CONCLUSION Tunnel endoscopy could be used to diagnose tumors. Moreover, we review the literature to provide guidance regarding the causes of esophagostenosis.展开更多

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

By years of clinical research, evidence has been accumulated. We conducted systematic review to assess outcomes of the treatment for CES, especially the role of endoscopic modalities. A total of 144 literatures were screened and reviewed. CES was categorized in fibromuscularthickening, tracheobronchial remnants(TBR) and membranous web, and the frequency was 54%, 30% and 16%, respectively. Therapeutic option includes surgery and dilatation, and surgery tends to be reserved for ineffective dilatation. An essential point is that dilatation for TBR type of CES has low success rate and high rate of perforation. TBR can be distinguished by using endoscopic ultrasonography(EUS). Overall success rate of dilatation for CES with or without case selection by using EUS was 90% and 29%, respectively. Overall rate of perforation with or without case selection was 7% and 24%, respectively. By case selection using EUS, high success rate with low rate of perforation could be achieved. In conclusion, endoscopic dilatation has been established as a primary therapy for CES except TBR type. Repetitive dilatation with gradual step-up might be one of safe ways to minimize the risk of perforation.展开更多

Patients who received < 45 Gy, treated for lesions below sternal notch, treated with palliative aim, treated with subsequent surgical resection, or diagnosed with synchronous hypopharyngeal cancer were excluded. Treatment failures were divided into local(occurring within the RT field), outfield-esophageal, and regional [occurring in regional lymph node(s)] failures. Factors predictive of esophageal stenosis requiring endoscopic dilation were analyzed.RESULTS Grade 1, 2, and 3 esophagitis occurred in 19(30.6%), 39(62.9%), and 4 patients(6.5%), respectively, without grade ≥ 4 toxicities. Sixteen patients(25.8%) developed post-RT stenosis, of which 7 cases(43.8%) were malignant. Four patients(6.5%) developed tracheoesophageal fistula(TEF), of which 3(75%) cases were malignant. Factors significantly correlated with post-RT stenosis were stage T3/4(P = 0.001), complete circumference involvement(P < 0.0001), stenosis at diagnosis(P = 0.024), and endoscopic complete response(P = 0.017) in univariate analysis, while complete circumference involvement was significant in multivariate analysis(P = 0.003). A higher dose(≥ 60 Gy) was not associated with occurrence of postRT stenosis or TEF. With a median follow-up of 24.3(range, 3.4-152) mo, the 2 y local control, outfield esophageal control, progression-free survival, and overall survival(OS) rates were 78.9%, 90.2%, 49.6%, and 57.3%, respectively. Factors significantly correlated with OS were complete circumference involvement(P = 0.023), stenosis at diagnosis(P < 0.0001), and occurrence of post-RT stenosis or TEF(P < 0.001) in univariate analysis, while stenosis at diagnosis(P = 0.004) and occurrence of post-RT stenosis or TEF(P = 0.023) were significant in multivariate analysis. CONCLUSION Chemoradiation for CEC was well tolerated, and a higher dose was not associated with stenosis. Patients with complete circumferential involvement require close follow-up.展开更多

Upper endoscopy revealed esophageal stenosis and extensive mucosa sloughing. Biopsies confirmed the diagnosis of graft-vs-host disease(GVHD). Balloon dilation,corticosteroids and cyclosporin resulted in marked clinical improvement. Gastrointestinal tract is involved in the majority of patients with chronic GVHD. Esophageal manifestations are rare and include vesiculobullous disease,ulceration,esophageal webs,casts or strictures. Sloughing esophagitis along with severe stenosis requiring endoscopic dilation has never been reported in this context.展开更多

Although multiple lymph nodes outside the RT field recurred, the local primary tumor within the RT field did not recur, even 17 mo after palliative RT of 30 Gy in 10 fractions. In this case, acute toxicity, such as myelosuppression or esophagitis, was not enhanced by increasing the fraction dose from 1.8-2.0 Gy to 3.0 Gy. Because 30 Gy in 10 fractions can be completed within a shorter time and is less expensive than 50.4 Gy in 28 fractions, we think that 30 Gy without oblique beams is a more favorable RT method for patients.展开更多

The improvement of survival observed over the previous two decades is multifactorial and largely attributable to advances in neonatal intensive care, neonatal anesthesia, ventilatory and nutritional support, antibiotics, early surgical intervention, surgical materials and techniques. Indeed, mortality is currently limited to those cases with coexisting severe life-threatening anomalies. The diagnosis of EA is most commonly made during the first 24 h of life but may occur either antenatally or may be delayed. The primary surgical correction for EA and TEF is the best option in the absence of severe malformations. There is no ideal replacement for the esophagus and the optimal surgical treatment for patients with long-gap EA is still contro-versial. The primary complications during the postoperative period are leak and stenosis of the anastomosis, gastro-esophageal reflux, esophageal dysmotility, fistula recurrence, respiratory disorders and deformities of the thoracic wall. Data regarding long-term outcomes and follow-ups are limited for patients following EA/TEF repair. The determination of the risk factors for the complicated evolution following EA/TEF repair may positively impact long-term prognoses. Much remains to be studied regarding this condition. This manuscript provides a literature review of the current knowledge regarding EA.展开更多

文摘Post-esophageal atresia anastomotic strictures and postcorrosive esophagitis are the most frequent types of cicatricial esophageal stricture.

文摘AIM To evaluate toxicity and treatment outcome of highdose radiotherapy(RT) for cervical esophageal cancer(CEC).METHODS We reviewed a total of 62 consecutive patients who received definitive RT for stage Ⅰ to Ⅲ cervical esophageal cancer between 2001 and 2015. Patients who received < 45 Gy, treated for lesions below sternal notch, treated with palliative aim, treated with subsequent surgical resection, or diagnosed with synchronous hypopharyngeal cancer were excluded. Treatment failures were divided into local(occurring within the RT field), outfield-esophageal, and regional [occurring in regional lymph node(s)] failures.

Sixteen patients(25.8%) developed post-RT stenosis, of which 7 cases(43.8%) were malignant. Four patients(6.5%) developed tracheoesophageal fistula(TEF), of which 3(75%) cases were malignant. Factors significantly correlated with post-RT stenosis were stage T3/4(P = 0.001), complete circumference involvement(P < 0.0001), stenosis at diagnosis(P = 0.024), and endoscopic complete response(P = 0.017) in univariate analysis, while complete circumference involvement was significant in multivariate analysis(P = 0.003). A higher dose(≥ 60 Gy) was not associated with occurrence of postRT stenosis or TEF. With a median follow-up of 24.3(range, 3.4-152) mo, the 2 y local control, outfield esophageal control, progression-free survival, and overall survival(OS) rates were 78.9%, 90.2%, 49.6%, and 57.3%, respectively. Factors significantly correlated with OS were complete circumference involvement(P = 0.023), stenosis at diagnosis(P < 0.0001), and occurrence of post-RT stenosis or TEF(P < 0.001) in univariate analysis, while stenosis at diagnosis(P = 0.004) and occurrence of post-RT stenosis or TEF(P = 0.023) were significant in multivariate analysis. CONCLUSION Chemoradiation for CEC was well tolerated, and a higher dose was not associated with stenosis. Patients with complete circumferential involvement require close follow-up.
文摘A 53-year-old male developed cervical esophageal stenosis after esophageal bypass surgery using a right colon conduit.The esophageal bypass surgery was performed to treat multiple esophageal strictures resulting from corrosive ingestion three years prior to presentation.Although the patient underwent several endoscopic stricture dilatations after surgery,he continued to suffer from recurrent esophageal stenosis.We planned cervical patch esophagoplasty with a pedicled skin flap of sternocleidomastoid(SCM) muscle.Postoperative recovery was successful,and the patient could eat a solid meal without difficulty and has been well for 18 mo.SCM flap esophagoplasty is an easier and safer method of managing complicated and recurrent cervical esophageal strictures than other operations.
文摘We report a case of a 56-year-old woman with a history of allogenic bone marrow transplantation for two years,complaining with dysphagia and weight loss. Upper endoscopy revealed esophageal stenosis and extensive mucosa sloughing. Biopsies confirmed the diagnosis of graft-vs-host disease(GVHD). Balloon dilation,corticosteroids and cyclosporin resulted in marked clinical improvement. Gastrointestinal tract is involved in the majority of patients with chronic GVHD. Esophageal manifestations are rare and include vesiculobullous disease,ulceration,esophageal webs,casts or strictures. Sloughing esophagitis along with severe stenosis requiring endoscopic dilation has never been reported in this context.
文摘BACKGROUND Esophageal stenosis is one of the main complications of endoscopic submucosal dissection(ESD)for the treatment of large-area superficial esophageal squamous cell carcinoma and precancerous lesions(≥3/4 of the lumen).Oral prednisone is useful to prevent esophageal stenosis,but the curative effect remains controversial.AIM To share our experience of the precautions against esophageal stenosis after ESD to remove large superficial esophageal lesions.METHODS Between June 2019 and March 2022,we enrolled patients with large superficial esophageal squamous cell carcinoma and high-grade intraepithelial neoplasia experienced who underwent ESD.Prednisone(50 mg/d)was administered orally on the second morning after ESD for 1 mo,and tapered gradually(5 mg/wk)for 13 wk.RESULTS In total,14 patients met the inclusion criteria.All patients received ESD without operation-related bleeding or perforation.There were 11 patients with≥3/4 and<7/8 of lumen mucosal defects and 1 patient with≥7/8 of lumen mucosal defect and 2 patients with the entire circumferential mucosal defects due to ESD.The longitudinal extension of the esophageal mucosal defect was<50 mm in 3 patients and≥50 mm in 11 patients.The esophageal stenosis rate after ESD was 0%(0/14).One patient developed esophageal candida infection on the 30th d after ESD,and completely recovered after 7 d of administration of oral fluconazole 100 mg/d.No other adverse events of oral steroids were found.CONCLUSION Oral prednisone(50 mg/d)and prolonged prednisone usage time may effectively prevent esophageal stricture after ESD without increasing the incidence of glucocorticoid-related adverse events.However,further investigation of larger samples is required to warrant feasibility and safety.

文摘BACKGROUND Congenital esophageal stenosis(CES)is a rare malformation of the digestive tract.Endoscopic dilation and thoracotomy have been the main treatments for CES.However,there is no well-defined management protocol.Magnetic compression stricturoplasty(MCS)has been used in refractory esophageal stricture in children after esophageal atresia.CASE SUMMARY We describe the first case of MCS for CES in one female child patient.The child(aged 3 years and 1 mo)was admitted due to frequent vomiting and choking after eating complementary food since 7 mo old.Esophagography and gastroendoscopy showed that there was stenosis in the lower esophagus,suggesting a diagnosis of CES.The patient did not receive any treatment for esophageal stricture including surgery or endoscopic dilation procedures before MCS.MCS procedure was smoothly conducted without complications.At 24 mo after MCS,durable esophageal patency without dysphagia was achieved.CONCLUSION MCS may serve as an alternative and efficient method for patients with CES.
文摘A 66-year-old man developed dysphagia during dinner and was evaluated 2d later in our hospital because of persistent symptoms.Upper gastrointestinal endoscopy showed no impacted food,but advanced esophageal cancer was suspected based on the presence in the upper esophagus of a large irregular ulcerative lesion with a thick white coating and stenosis.Further imaging studies were performed to evaluate for metastases,revealing circumferential esophageal wall thickening and findings suggestive of lung and mediastinal lymph node metastases.However,dysphagia symptoms and the esophageal ulcer improved after hospital admission,and histopathological examination of the esophageal mucosa revealed only nonspecific inflammation.At the timeof symptom onset,the patient had been eating stewed beef tendon(Gyusuji nikomi in Japanese) without chewing well.Esophageal ulceration due to steakhouse syndrome was therefore diagnosed.The lung lesion was a primary lung cancer that was surgically resected.Although rare,steakhouse syndrome can cause large esophageal ulceration and stenosis,so care must be taken to distinguish this from esophageal cancer.
文摘Dyspnea from tracheal stenosis due to compression by a tumor is an emergency that complicates therapy in oncology.We report a case of advanced esophageal cancer in a 56-year-old male who developed severe dyspnea due to airway compression by mediastinal lymph node enlargement.We used epinephrine by subcutaneous injection and aerosol inhalation to temporarily relieve dyspnea while the patient received bevacizumab and chemotherapy.The dyspnea had subsided considerably after 5 days,and the mediastinal lymph nodes were significantly reduced after 2 cycles of chemotherapy.However,the patient died of massive tracheal hemorrhage 2 months later.
文摘BACKGROUND Superior mesenteric artery syndrome(SMAS)is a rare condition,characterized by duodenal obstruction caused by compression of its third part by the superior mesenteric artery(SMA).Most cases of SMAS are associated with weight loss,and the most frequent clinical manifestations are nausea,vomiting,postprandial fullness,and abdominal pain.Treatment of SMAS is usually conservative,consisting mainly of adequate nutritional support,but in refractory cases surgery may be necessary,with gastrojejunostomy and duodenojejunostomy being the most commonly performed procedures.CASE SUMMARY We describe the case of a man in his forties with a pre-existing diagnosis of esophageal stricture due to sodium hydroxide ingestion,who suffered significant weight loss after replacement of his jejunostomy tube.He was admitted to the hospital due to pain and abdominal distension.A computerized tomography scan showed significant distension of the stomach and duodenum with narrowing of the duodenum at the point at which it is crossed by the superior mesenteric artery,thus establishing the diagnosis of SMAS.Due to the presence of the esophageal stricture,the patient was incapable of emesis;however,passage of a nasogastric tube for decompression was not possible.Considering the risk of gastric perforation due to distention,we opted for surgical treatment in the form of a surgical gastrojejunostomy after which he showed complete resolution of all symptoms and was discharged from the hospital 5 d after the procedure.CONCLUSION Diagnosis of SMAS can be challenging in patients with esophageal stenosis,and risk of gastric perforation may preclude conservative treatment.

文摘BACKGROUND The stent embedded in the esophageal mucosa is one of the complications after stenting for esophageal stricture.We present a case of stent adjustment with the aid of a transparent cap after endoscopic injection of an esophageal varices stent.CASE SUMMARY A 61-year-old male patient came to the hospital with discomfort of the chest after the stent implanted for the stenosis because of endoscopic injection of esophageal varices.The gastroscopy was performed,and the stent embedded into the esophageal mucosa.At first,we pulled the recycling line for shrinking the stent,however,the mucosa could not be removed from the stent.Then a forceps was performed to remove the mucosa in the stent,nevertheless,the bleeding form the mucosa was obvious.And then,we used a transparent cap to scrape the mucosa along the stent,and the mucosa were removed successfully without bleeding.CONCLUSION A transparent cap helps gastroscopy to remove the mucosa embedded in the stent after endoscopic injection of the esophageal varices stent.
文摘We report on a patient who remained cancer-free for an extended time after palliative radiotherapy(RT) and chemotherapy(nedaplatin plus 5-fluorouracil) treatment for stage Ⅳ(cT3N3M1) esophageal squamous cell carcinoma. Although multiple lymph nodes outside the RT field recurred, the local primary tumor within the RT field did not recur, even 17 mo after palliative RT of 30 Gy in 10 fractions. In this case, acute toxicity, such as myelosuppression or esophagitis, was not enhanced by increasing the fraction dose from 1.8-2.0 Gy to 3.0 Gy. Because 30 Gy in 10 fractions can be completed within a shorter time and is less expensive than 50.4 Gy in 28 fractions, we think that 30 Gy without oblique beams is a more favorable RT method for patients.

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

文摘BACKGROUND Repeated endoscopic probe dilatation is the most preferred treatment for esophageal stenosis which may cause high levels of symptom distress in the patient’s home rehabilitation stage.AIM To explore the changes in the symptom distress level and its correlation with the dilation effect in patients with esophageal carcinoma undergoing repeated dilations for lumen stenosis.METHODS The difference(R2-R1)between the diameter of the esophageal stenosis opening(R1)of the patients before dilation(R1)and after dilation(R2)was calculated to describe the extent and expansion of the esophageal stenosis before and after dilation.The M.D.Anderson Symptom Inventory was used to describe the symptom distress level of patients with dilation intermittence during their stay at home and to explore the correlation between the dilation effect and symptom distress level.RESULTS The diameter of the esophagus(R1)increased before each dilation in patients undergoing esophageal dilation(P<0.05).The diameter(R2)increased after dilation(P<0.05);the dilation effect(R2-R1)decreased with the number of dilations(P<0.05).The total symptom distress score significantly increased with the number of dilations(P<0.05).The symptom distress scores of the patients were negatively correlated(P<0.05)with the previous dilation effect(R2-R1)and the esophageal diameter(R2)after the previous dilation.After the 1 st to 4 th dilations,the patient’s symptom distress score was negatively correlated with the esophageal diameter(R12)before the next dilation,while there was no significant correlation(P>0.05)with the other dilations.CONCLUSION In patients who have undergone repeated dilations,better effect stands for lower symptom distress level and the increase in symptom distress has a prompt effect on the severity of the next occurrence of restenosis.
