Abstract
ObjectiveTo evaluate the dosimetric characteristics and the clinical application of radioactive iodine-125 brachytherapy stent (RIBS) in malignant esophageal obstruction.MethodsThe dose distribution of RIBS with different seed spacing, diameter and length was studied by treatment planning system (TPS) calculation, thermoluminescence dosimeter (TLD) measurement and Monte Carlo (MC) data fitting. And the data of esophageal cancer patients who were treat with this type of RIBS was analyzed retrospectively.ResultsDoses around the RIBS calculated by the TPS lay between those measured by the TLDs and those simulated by the MC, and the differences between the three methods were significant (p<0.05), the overall absolute dose differences among the three methods were small. Dose coverage at 1.5 cm from the center was comprehensive when the activity reached 0.6 mCi. Both the conformability and the uniformity of isodose lines produced by a seed spacing of 1.0 cm were superior to those produced by a seed spacing of 1.5 cm. The data of 50 patients treated with RIBS was analyzed. They were followed up until February 2020 when all of the patients died. The overall improvement rate of dysphagia after RIBS implant was 90%. Moderate and severe complications with an incidence of more than 10% were hematemesis (28%), pain (20%), and lung infection (10%). Stent restenosis occurred in 4 patients at a median interval of 108 days from the procedure. The overall incidence of fatal complications was 38% (including hematemesis, infection and asphyxia). The median survival time of patients with and without a history of radiotherapy were 3.4 months and 6 months, respectively, the difference of which was significant (p=0.021). No other factors affecting survival were identified. For patients with and without a history of radiotherapy, the incidences of fatal complications were 51.7% and 19%, respectively (p=0.019). No correlation between dose and stent restenosis was found.ConclusionTPS calculations are suitable for clinical applications. RIBS can effectively alleviate obstructive symptoms for patients with malignant esophageal obstruction, but the incidence of fatal complications was high, care should be taken when choosing this treatment.

Abstract
BACKGROUND The aim of this study was to assess the clinical outcomes of palliative interventions for patients with incurable locally advanced or metastatic esophageal carcinoma. METHODS A total of 131 patients with thoracic esophageal carcinoma who underwent palliative interventions were enrolled. Insertion of a self-expandable metallic stent (SEMS), tube enterostomy for enteral nutrition (EN), and palliative esophagectomy (PE) were performed in 38, 65, and 28 patients, respectively. The clinicopathological characteristics and clinical outcomes of each group were retrospectively reviewed. RESULTS Patients in the EN group frequently received chemoradiotherapy (P < 0.01). SEMS insertion, but not PE or EN, improved the mean dysphagia score after the intervention (P < 0.01). For the SEMS, EN, and PE groups, the occurrence of intervention-related complications was 31.6, 10.8, and 96.4%, respectively, the median survival time was 88, 208, and 226 days (P < 0.01), and the mean ratio of duration of home care to survival time was 28.9, 38.5, and 39.6% (P = 0.95). CONCLUSIONS SEMS insertion effectively relieved obstructive symptoms, but had no survival benefit. Tube enterostomy showed a low complication rate and has the potential to improve survival in combination with additional treatment, with no palliation of obstructive symptoms.

Abstract
BACKGROUND This study aims to report our experience with esophageal self-expendable metal stents for the palliation of malignant dysphagia and tracheoesophageal fistulas caused by lung cancer. METHODS Esophageal self-expandable metal stents were deployed in 56 patients (55 males, 1 female; mean age 63.5 years; range, 42 to 79 years) with malignant dysphagia due to lung cancer between August 2002 and May 2018. Of the patients, 34 had received previous chemoradiotherapy, eight only chemotherapy, and three only radiotherapy, while four had pneumonectomy. Tracheoesophageal fistula was coexisting in 12 patients (21%). Stents were inserted under fluoroscopic control over guide-wire in 28 patients and under flexible endoscopic control in the remaining 28 patients. One stent was used in all patients, except two patients with tracheoesophageal fistula, one patient who had an external compression causing downward migration of stent, and two patients who had tumor progression. RESULTS Dysphagia improved in all patients after stent insertion. Tracheoesophageal fistula was sealed off in all patients. All patients remained asymptomatic without dysphagia symptoms during the follow-up period except for two patients who underwent gastrostomy. All patients with tracheoesophageal fistula died. Their mean duration of survival was 2.8 months. Of the patients with tracheoesophageal fistula, one died of mediastinitis, one died of esophageal perforation, while the others died of cancer-related reasons. Of the dysphagia patients without tracheoesophageal fistula, all died except for two patients. Mean duration of survival in this group was 4.3 months. CONCLUSION Dysphagia in lung cancer may have many underlying reasons. Self-expandable metal stents may provide satisfactory relief of dysphagia symptoms with minimal morbidity after a single procedure in patients with limited lifespan.

Abstract
BACKGROUND Malignant dysphagia can result in poor nutritional status with severe weight loss. Rapid relief from dysphagia can be achieved with esophageal self-expanding metal stents (SEMSs), a minimally invasive method. In this study, we evaluated the usefulness of SEMSs for malignant dysphagia. METHODS Between 2012 and 2015, 119 patients with malignant dysphagia underwent esophageal SEMS insertion with endoscopic assistance. Their demographics and clinical outcomes were collected. Factors associated with stent-related complications and patient survival were evaluated. All data were retrospectively analyzed. RESULTS The mean age of the 119 patients was 64.9 ± 11.6 years, and 25 (21%) were female. Seventy-five patients (63.0%) had squamous carcinoma, majority of which were located in the lower thoracic esophagus (n = 42), followed by middle thoracic esophagus (n = 19) and upper esophagus (n = 10). Eighty patients (67.2%) underwent SEMS insertion at diagnosis. Technical and clinical success rates were 99.2 and 89.9%, respectively. Complications occurred in 47 patients (39.5%); the most common complication was migration (36.3%), followed by pain and obstruction. The median stent patency time was 145 days (95% confidence interval 55.19-234.81 days). Gastric cancer (odds ratio 3.51, 95% confidence interval 1.21-10.15; p = 0.021) and a 20-mm-wide stent (odds ratio 2.922, 95% confidence interval 1.237-6.904; p = 0.015) were risk factors for complications. CONCLUSIONS SEMSs are effective in palliation of malignant dysphagia. However, stent-related complications should be borne in mind, particularly in patients with gastric cancer with esophageal invasion and with larger width stents.

Abstract
BACKGROUND AND OBJECTIVES The self-expandable metal stent (SEMS) is an alternative for several possible surgical and palliative treatments of upper gastrointestinal obstructions that occur in several disease states. The present study was performed to describe a single-center experience with upper gastrointestinal stents. METHODS All patients at a single center who had an SEMS placed for the treatment of obstruction over a 3-year period were retrospectively evaluated. Pre- and postoperative dysphagia scoring was calculated and used to evaluate postprocedure improvement in quality of life. Procedural success and early and late complication rates were investigated. RESULTS A total of 171 endoscopic procedures were performed in 73 patients. Procedural success was 95.8% (n = 69) and dilatation was performed in 80 patients. The rate of perioperative complication was 26% (n = 19). After 1 month, stents were patent in all patients (n = 73). Stent obstruction was noted in 6 patients: 2 each at 2, 7, and 10 months. CONCLUSION SEMS usage for palliative and curative purposes in benign or malignant upper gastrointestinal system obstructions is an efficient and reliable treatment method with advantages, such as shortening hospital stay, decreased pain, cost-effectiveness, and low mortality-morbidity rates when compared to surgical procedures, and a high rate of clinical success.

Abstract
BACKGROUND Self-expandable metal stents (SEMSs) are the main palliative modality used in inoperable oesophageal cancer. Other palliative modalities, including argon plasma coagulation (APC), have also been used. OBJECTIVE The purpose of this study was to assess the relative efficacy of SEMS and APC regarding the survival of patients with inoperable oesophageal cancer, not receiving chemo/radiotherapy. METHODS Single centre, retrospective analysis of all patients (n = 228) with inoperable oesophageal cancer between January 2000 and July 2014, not receiving chemo-radiotherapy, treated with SEMS (n = 160) or APC (n = 68) as primary palliation modalities. Cox regression analysis was performed to identify individual factors affecting survival and Kaplan-Meier curves were created for patients treated with APC and SEMS for stage III and IV disease. Survival intervals were compared by the log-rank test. RESULTS Type of treatment was the only statistically significant factor affecting survival, after disease stage stratification (hazard ratio (HR): 1.36, 95% confidence interval (CI): 1.13-1.65 of SEMS over APC, p: 0.002). Median survival for patients treated with APC and SEMS was 257 (interquartile range (IQR): 414, 124) and 151 (IQR: 241, 61) days respectively in stage III disease. It was 135 (IQR: 238, 43) and 70 (IQR: 148, 32) days respectively in stage IV disease. Both differences were statistically significant (p = 0.02 and 0.05 respectively). CONCLUSIONS APC is a promising palliation modality in inoperable oesophageal cancer, when patients are not candidates for chemo-radiotherapy. A randomized controlled trial will be needed to confirm those results.

Abstract
BACKGROUND We determined the feasibility of, and tissue response to silicone-covered biodegradable magnesium- and plastic-stent insertion into the esophagus in rabbits. METHODS The mechanical compression-recovery characteristics and degradation behaviors of the magnesium stent were investigated in vitro. A total of 45 rabbits were randomly divided into a magnesium- (n = 15) and a plastic- (n = 15) stent group, and underwent stent insertion into the lower third of the esophagus under fluoroscopic guidance; a control group (n = 15) did not undergo the intervention. Esophagography was performed at 1, 2, and 4 weeks. Five rabbits in each group were euthanized at each time point for histological examination. RESULTS Silicone-covered magnesium stents showed similar radial force to plastic stents (p > 0.05). The magnesium stents degraded rapidly in an acidic solution, but 90.2% ± 3.1% of the residual mass was maintained after a 2-week degradation in a solution with a pH of 4.0. All stent insertions were well tolerated. Magnesium stents migrated in six rabbits (one at 1 week, one at 2 weeks and four at 4 weeks), and plastic stents migrated in three rabbits (one at 2 weeks and two at 4 weeks; p > 0.05). Esophageal wall remodeling (thinner epithelial and smooth muscle layers) was similar in both stented groups (p > 0.05), and the esophagus wall was found to be significantly thinner in the stented groups than in the control group (p < 0.05). Esophageal injury and collagen deposition following stent insertion were similar and did not differ from the control group (p > 0.05). CONCLUSIONS Esophageal silicone-covered magnesium stents provided reliable support for at least 2 weeks, with acceptable migration rates and without causing severe injury or tissue reaction compared with plastic stents.

Abstract
OBJECTIVES Determine the feasibility of and tissue response to biodegradable magnesium-silicone stent insertion into the oesophagus of rabbits. METHODS Mechanical compression-recovery and degradation behaviours of the stents were investigated in vitro. Thirty rabbits were randomly divided into a magnesium-silicone stent group (n = 15) that received stent insertion into the lower 1/3 of the oesophagus under fluoroscopic guidance and a control group (n = 15). Oesophagography was performed at 1, 2 and 4 weeks. Five rabbits in each group were euthanized at each time point for histological examination. RESULTS Magnesium-silicone stents showed good flexibility and elasticity, and degraded more slowly than bare stents at pH 4.0 and 7.4. All stent insertions were well tolerated. The oesophageal diameters at 1, 2 and 4 weeks were 9.7 ± 0.7, 9.6 ± 0.8 and 9.6 ± 0.5 mm, respectively (vs. 9.2 ± 0.8 mm before intervention; P > 0.05). Stent migration occurred in six rabbits (one at 1 week, one at 2 and four at 4). Microscopy demonstrated dilation of the oesophageal wall within 1 week of insertion. Oesophageal injury and collagen deposition following stent insertion were similar to control (P > 0.05). CONCLUSIONS Oesophageal magnesium-silicone stent insertion was feasible and provided reliable support for 2 weeks without causing oesophageal injury or collagen deposition. KEY POINTS • Mg stent provided apparently adequate radial force and silicone membrane reduced magnesium biodegradation • Stent insertion provided good support for at least 2 weeks before biodegradation • Stenting effectively resulted in oesophageal wall remodelling, without demonstrable injury.

J Dig Dis 2015; 16:575-84.

Abstract
OBJECTIVE To evaluate the efficacy and feasibility of esophageal self-expanding metal stents (SEMS) insertion for malignant esophageal obstruction (MEO) in patients with or without additional palliative treatment. METHODS We retrospectively reviewed the medical records of the patients with SEMS for MEO. Baseline characteristics, changes in Mellow-Pinkas dysphagia score, and adverse events were collected and compared according to the presence and absence of additional palliative treatment. RESULTS Altogether 192 patients underwent 236 SEMS insertion procedures. Esophageal, gastric cardiac and lung cancers were seen in 46.4%, 33.3% and 15.1% of the patients, respectively. Their Mellow-Pinkas score significantly decreased within one week and one month after the SEMS insertion (1.66 ± 0.79 and 1.71 ± 0.87 vs 3.09 ± 0.79, respectively, P = 0.000). Complications occurred in 54 (22.9%) of 236 SEMS insertion; there were 28 (11.9%) stent obstruction, 5 (2.1%) perforation (2.1%), 10 (4.2%) stent migration, 5 (2.1%) tracheoesophageal fistula, but no procedure-related death. Most complications were managed by inserting additional SEMS. The risk of stent obstruction was significantly higher in uncovered stents than in covered SEMS (OR 3.56, 95% CI 1.39-9.12, P = 0.006). Mean duration to the development of complications was 74.8 ± 111.1 days. Overall survival (169.0 ± 127.8 days vs 96.4 ± 90.6 days, P = 0.000) and stent patency (143.3 ± 123.9 days vs 67.6 ± 71.3 days, P = 0.000) were significantly favorable in patients with SEMS and additional palliative treatments compared with those with SEMS alone. CONCLUSION SEMS insertion is effective and safe for treating MEO, and additional palliative treatment might lengthen stent patency by prolonging the patient's survival.

Abstract
Esophageal adenocarcinoma (EAC) is rapidly increasing in incidence in Western cultures. Barrett's esophagus is the presumed precursor lesion for this cancer. Several other risk factors for this cancer have been described, including chronic heartburn, tobacco use, white race, and obesity. Despite these known associations, most patients with EAC present with symptoms of dysphagia from late-stage tumors; only a small number of patients are identified by screening and surveillance programs. Diagnostic analysis of EAC usually commences with upper endoscopy followed by cross-sectional imaging. Endoscopic ultrasonography is useful to assess the local extent of disease as well as the involvement of regional lymph nodes. T1a EAC may be treated endoscopically, and some patients with T1b disease may 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 prognosis, whereas few patients with advanced disease have long-term survival.

Abstract
BACKGROUND Fully covered esophageal self-expandable metal stents (SEMSs) are potentially removable but can be associated with high migration rates. For precise positioning, non-foreshortening SEMSs are preferred. Recently, a new fully covered non-foreshortening SEMS with anti-migration features was introduced. OBJECTIVE To evaluate the efficacy and safety of this new esophageal SEMS. DESIGN Retrospective study. SETTING Single, tertiary-care center. PATIENTS Consecutive patients with malignant and benign strictures with dysphagia grade of ≥3 and patients with fistulas/leaks were studied. INTERVENTIONS Stent placement and removal. MAIN OUTCOME MEASUREMENTS Technical success in stent deployment/removal, efficacy in relieving dysphagia and sealing fistulas/leaks, and adverse events. RESULTS Forty-three stents were placed in 35 patients (mean [± standard deviation] age 65 ± 11 years; 31 male), 24 for malignant and 11 for benign (5 strictures, 6 leaks) indications. Technical success in precise SEMS placement was 100%. The after-stent dysphagia grade improved significantly (at 1 week: 1.5 ± 0.7; at 4 weeks: 1.2 ± 0.4; baseline: 3.8 ± 0.4; P < .0001). Twenty stents were removed for clinical indications, with technical success of 100%. All leaks sealed after SEMS placement and did not recur after stent removal. All benign strictures recurred after stent removal. Adverse events included migration (14%), chest pain (11%), and dysphagia from tissue hyperplasia (6%). There was no stent-related mortality. LIMITATIONS Nonrandomized, single-center study. CONCLUSION The new esophageal SEMS was effective in relieving malignant dysphagia, allowed for precise placement, and was easily removable. It was effective in treating benign esophageal fistulas and leaks. Stent-related adverse events were acceptable.
