Abstract
INTRODUCTION Advances in microfabrication, automation, and computer engineering seek to revolutionize small-scale devices and machines. Emerging trends in medicine point to smart devices that emulate the motility, biosensing abilities, and intelligence of cells and pathogens that inhabit the human body. Two important characteristics of smart medical devices are the capability to be deployed in small conduits, which necessitates being untethered, and the capacity to perform mechanized functions, which requires autonomous shape-changing. AREAS COVERED We motivate the need for untethered shape-changing devices in the gastrointestinal tract for drug delivery, diagnosis, and targeted treatment. We survey existing structures and devices designed and utilized across length scales from the macro to the sub-millimeter. These devices range from triggerable pre-stressed thin film microgrippers and spring-loaded devices to shape-memory and differentially swelling structures. EXPERT OPINION Recent studies demonstrate that when fully enabled, tether-free and shape-changing devices, especially at sub-mm scales, could significantly advance the diagnosis and treatment of GI diseases ranging from cancer and inflammatory bowel disease (IBD) to irritable bowel syndrome (IBS) by improving treatment efficacy, reducing costs, and increasing medication compliance. We discuss the challenges and possibilities associated with ensuring safe, reliable, and autonomous operation of these smart devices.

Indian J Palliat Care 2023; 29:64-69. [PMID: 36846283 PMCID: PMC9945415 DOI: 10.25259/ijpc_106_2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 11/19/2022] [Indexed: 01/13/2023] Open
Abstract
Objectives Management of malignant gastrointestinal (GI) obstruction presents a significant challenge. Most patients are in a profoundly decompensated state due to underlying malignancy and are not ideal candidates for invasive surgical procedures. Self-expandable metallic stents (SEMSs) are used to provide permanent or temporary patency in all endoscopically accessible stenosis of the GI tract. In this study, it is aimed to analyse the characteristics and the efficacy of patients with malignant stenosis treated with SEMS, in all segments of the GI tract. Material and Methods The sample consisted of 60 patients who underwent SEMS replacement, between 10 March 2014 and 16 December 2020, to treat malignant-related strictures in the GI tract at the Gastroenterology Department of the Health Sciences University Umraniye Training and Research Hospital. The data of the patients, hospital data processing database and electronic endoscopic database records were retrospectively scanned and recorded. The general characteristics of the patients and the treatment-related features were analysed. Results The mean age of patients who were placed SEMS was 69.7 ± 13.7 years. Uncovered (15%, n: 9), fully covered (13.3%, n: 8), or partially covered (71.6%, n: 43) SEMS were successfully placed in all patients. Clinical success in patients with SEMS was 85.7% in the esophagus, 100% in the small intestine and 90.9% in the stomach and colon. About 11.4% migration, 14.2% pain, 11.4% overgrowth and 5.7% ingrowth were detected in patients who had SEMS placed in the oesophagus. Pain was detected in 9.1% and ingrowth in 18.2% of patients who had SEMS placed in the stomach. Pain was detected in 18.2% of the patients who had SEMS placed in the colon and migration was found in 9.1%. Conclusion SEMS implant is a minimally invasive effective method in the palliative treatment of malignant strictures of the GI tract.

Abstract
BACKGROUND Pharyngoesophageal stenosis (PES) is a serious complication that substantially impacts functional outcomes and quality of life (QOL) for up to a third of head and neck cancer patients who undergo radiotherapy. Dysphagia is often multifactorial in nature and is a devastating complication of treatment that impacts patients' QOL, general health and overall wellbeing. The authors detail the clinical presentation, risk factors, imaging characteristics, preventive measures, and multimodality treatment options for PES. METHODS The authors present a comprehensive management algorithm for PES, including treatment by dilation, stenting, spray cryotherapy and dilation, and reconstructive treatment options utilizing different pedicled and free flaps. RESULTS The authors advocate for a thorough assessment of the extent and degree of pharyngoesophageal involvement of PES to determine the optimal management strategy. CONCLUSIONS The development of post treatment dysphagia requires appropriate imaging and biopsy, when indicated, to rule out the presence of persistent/recurrent cancer. Multidisciplinary management by a team of physicians well-versed in the range of diagnostic and therapeutic interventions available for PES is critical to its successful management.

Abstract
Anastomotic leakage is one of the major complications of esophageal surgery with a high mortality rate and significant morbidity. We describe a case of severe anastomotic leakage close to the hypopharynx after esophageal cancer resection. Despite the conservative management with external drainage, the severe leak did not improve. A fully covered self-expandable metal stent (SEMS) with short flares, which was designed for the cervical esophagus, was subsequently placed bridging the anastomosis to seal the fistula. The post-procedural course was uneventful, and the stent was endoscopically removed after three weeks without any complications. The patient was discharged home three weeks after the stent removal. Our results suggest that placement of fully covered SEMS with short flares may be a safe and effective treatment in this condition of patients.

Abstract
Background In our institutions, there are two types of stents used: the Boston Scientific Wallflex (Marlborough, Massachusetts) and Merit Medical Endotek (South Jordan, Utah). So we performed this retrospective study to compare complication rates in various esophageal disorders to improve our quality of care. Methods Charts were reviewed to capture gender, indications of stent placement, stent length/diameter, age of the patient at the time of stent placement, length of hospital stay, physicians performing a procedure, and complications within 90 days of stent placement. Results A total of 67 patients (71.6% male) underwent stent placement (WallFlex 49.3% and Merit 50.8%) for malignant (68.7%) mainly esophageal obstruction by primary esophageal cancer (89.1%) and benign causes (31.3%) mainly esophageal leak (66.7%). Merit and WallFlex used in malignant conditions were 82.4% and 54.6%, respectively, and in benign conditions, they were 17.7% and 45.5%, respectively. The mean age at which endoscopy was performed was 64. Complications post Merit and WallFlex placement were 79.4% and 60.6%, respectively. Complications with malignant and benign conditions were 73.9% and 61.9%, respectively. Complications with 19, 18, and 23 mm diameters were 75.0%, 66.7%, and 69.4%, respectively. Complications with 120, 150, 100, 15, 12, 10 mm stent lengths were 84.6%, 58.3%, 58.8%, 80.0%, 75.0%, and 33.3%, respectively. Conclusion Our study showed that the Merit stent was mainly used, and the major indication of stent placement was a malignant condition. Major complications were seen when the reason for stent placement was a malignant condition, the diameter was 19 mm, the length was 120 mm, and the use of the Merit stent.

Abstract
Background The aim of this study was to analyze the safety and effectiveness of stenting using partially covered self-expandable stents in palliation of dysphagia in patients with unresectable esophageal cancer. Methods Retrospective analysis of hospital records of all patients who underwent esophageal stenting in the period 2008–2015 was performed. The study included patients with unresectable esophageal and esophagogastric cancer. Results There were 442 patients included. Mean age was 56 years (range 28–89), and 379 were males. In 40 (9.0%) patients, stenting was performed in the cervical, in 150 (39.3%)—in the middle thoracic, in 141 (31.9%)—in lower thoracic esophagus and in 111 (25.1%)—in the esophagogastric junction. Stenting resulted in significant alleviation of dysphagia grade (3.0 vs. 1.0, p = 0.00001). During the follow-up, 55 (12.4%) patients experienced recurrent dysphagia due to tumor or granulation tissue overgrowth, and in 18 (4.1%) patients, migration of the stent occurred, for which an independent risk factor was adjuvant chemo- and/or radiation therapy (p = 0.001). Minor complications included chest pain (54.5%), delayed complete stent expansion (12.0%), feeling of a foreign body (25.3%), hiccup (1.6%), gastroesophageal reflux (45.6%) and post-discharge pneumonia (2.5%). A feeling of a foreign body in the esophagus was significantly more common after stenting of the cervical esophagus (p = 0.0001), and hiccup was more common after stenting of the esophagogastric junction (p = 0.02). Major complications included bleeding (1.3%), respiratory insufficiency (0.7%), esophageal perforation (0.9%) and irregular heartburn (2.3%). Overall procedure-related mortality was 0.4%. The median survival time was 117.8 days (range 2–732). Conclusions Stenting is an effective procedure in relieving dysphagia in patients with unresectable malignant esophageal stenosis and is associated with low rate of postoperative and long-term complications.

Abstract
Introduction: Esophageal cancer is diagnosed with more than 480,000 patients per year and this disease became the eighth most common cancer worldwide. Aim: In this study, we tried to investigate the role of chemoradiotherapy in decreasing the severity of dysphagia and increasing the quality of life (QOL) in patients with esophageal cancer. Methods: Patients were diagnosed with esophageal cancer, which were proven by pathological studies. Also, all of these patients had no primary surgeries for their esophageal cancer. For determining the cancer staging, the endoscopy, sonography, abdominal and pelvic computed tomography scans were assessed. Results: In this study, 81% of patients showed responsiveness to the chemoradiotherapy and their dysphagia significantly was getting improved after treatment in comparison to the initial date (P<0.01). Also, the pain score significantly decreased after chemoradiotherapy. However, the analysis failed to show any significant difference between before and after treatment in 19% of patients who had high degrees of dysphagia and they were the candidate for surgery and stent putting. On the other hand, we demonstrated that there is no correlation between sex, age, tumor type and location with the recovery rate of dysphagia. In addition, we showed that none of the patients showed the recurrence of dysphagia during the study (1.5 years). Conclusion: Chemoradiotherapy could be a novel treatment for patients with inoperable esophageal cancer to reduce the severity of dysphagia and increasing the QOL of these individuals.

Abstract
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.

Abstract
The art and science of using stents to treat dysphagia and seal fistula, leaks and perforations has been evolving. Lessons learnt from the deficiencies of previous models led to several improvements making stent deployment easier, and with some designs, it was also possible to remove the stents if needed. With these improvements, besides malignant dysphagia, newer indications for using stents emerged. Unfortunately, despite several decades of evolution, as yet, there is no perfect stent that "fits all." This article is an overview of how this evolution process happened and where we are currently with using stents to manage patients with dysphagia and with other esophageal disorders.

Abstract
AIM: To evaluate if differences exist between self-expanding esophageal metal stents (SEMS) and self-expanding esophageal plastic stents (SEPS) when used for benign or malignant esophageal disorders with regard to safety, efficacy, clinical outcomes, placement ease and cost.
METHODS: A retrospective analysis was performed to evaluate outcome in patients having SEPS/SEMS placed for malignant or benign esophageal conditions from January 2005 to April 2012. Inclusion criteria was completed SEMS/SEPS placement. Outcomes assessed included technical success of and time required for stent placement, procedure-related complications, need for repeat intervention, hospital stay, mortality and costs.
RESULTS: Forty-three patients underwent stent placement for either benign/malignant esophageal disease during the study period. Thirty patients had SEMS (25 male, mean age 59.6 years old) and 13 patients had SEPS (10 male, mean age 61.7 years old). Placement outcome as well as complication rate (SEPS 23.1%, SEMS 25.2%) and in-hospital mortality (SEPS 7.7%, SEMS 6.7%) after placement did not differ between stent types. Migration was the most frequent complication reported occurring equally between types (SEPS 66.7%, SEMS 57.1%). SEPS was less costly than SEMS, decreasing institutional cost by $255/stent.
CONCLUSION: SEPS and SEMS have similar outcomes when used for benign or malignant esophageal conditions. However, SEPS use results in decreased costs without impacting care.

Abstract
Advanced squamous cell carcinoma of the oesophagus and gastroesophageal junction usually requires palliative treatment, and the method of choice is stenting. There are several types of stents currently available, including: self-expandable metallic stents (fully or partially covered); self-expandable plastic stents; biodegradable stents. Each of the mentioned stents has its advantages and limitations, and requires a proper, patient-tailored selection. Due to the close anatomical relationship between the oesophagus and bronchial tree, some patients may require bilateral stenting. Oesophageal stenting may not only be considered as a palliative procedure, but can also be implemented to alleviate dysphagia during preoperative chemotherapy and/or radiotherapy.

Abstract
Self-expanding metal stents (SEMS) are the current standard for relief of malignant esophageal dysphagia. Self-expanding plastic stents (SEPS) are also used for relief of malignant esophageal dysphagia and as neoadjuvant therapy due to their relative ease of removability. The innovations in design of both SEMS and SEPS have made their use more prevalent in patients with malignant dysphagia. We review the current literature on esophageal stents, including general concepts, indications, contraindications, SEMS and SEPS models, complications and their management, implications of tumor location, cost-effectiveness of stents in comparison with other modalities, and quality of life after stent placement.

Battaglia G, Antonello A, Realdon S, Cavallin F, Giacomini F, Ishaq S. Feasibility, efficacy and safety of stent insertion as a palliative treatment for malignant strictures in the cervical segment of the esophagus and the hypopharynx. Surg Endosc 2016; 30:159-67. [PMID: 25829063 DOI: 10.1007/s00464-015-4176-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2014] [Accepted: 03/19/2015] [Indexed: 12/23/2022]
Abstract
BACKGROUND 50% of esophageal cancers are inoperable at the time of diagnosis, and around 15% involve the cervical esophagus. The hypopharynx is often involved by these malignancies as well. Palliation of cervical esophageal malignancies through stent insertion is considered limited due to technical challenges, poor patient tolerance and high complication rate. The aim of this study is to review our experience with stent insertion in the cervical segment of the esophagus and to evaluate outcome differences between stent insertions involving or sparing the hypopharynx. METHODS We retrospectively reviewed data on 69 consecutive patients that underwent stent insertion for malignant strictures in the cervical esophagus at our Department. Patients were divided according to involvement or sparing of the lower hypopharynx. Dysphagia severity was measured with the Mellow-Pinkas scale before the procedure and on monthly follow-ups. Any complication and its management were recorded. The main outcome parameters were as follows: dysphagia improvement, rate of successful dysphagia palliation (i.e., a reduction of the score to 0 or 1 after stent insertion) and complication rate. Multivariable analysis was carried out to assess the influence of patient- and procedure-related factors on the outcome of the procedure. RESULTS Stent insertion was achieved in 100% patients. At 4 weeks, dysphagia score improved from a median of 3-0 (p < 0.001), and a successful palliation was achieved in 76.8% patients. The 30-day mortality rate was 14.5%. Successful palliation throughout the follow-up was achieved in 72.9% of the surviving patients. Complications occurred in 31.9% patients. Dilation before stent insertion was associated with a less efficient short-term dysphagia palliation (OR 6.77, 95% CI 1.46-31.29, p = 0.02). CONCLUSIONS Stent insertion is a safe and effective palliative treatment for malignant cervical esophageal strictures. Results are consistent even in patients with hypopharyngeal lesions. Dilation should be avoided before stent insertion.

Abstract
The diagnosis and the treatment of anastomotic leak after esophagectomy are the keys to reduce the morbidity and mortality after this surgery. The stent plays an important role in the treatment of the leakage and in the prevention of reoperation. We have analyzed the database of the section of the esophagogastric surgery of Donostia University Hospital from June 2003 to May 2012. It is a retrospective study of 113 patients with esophagectomy resulting from tumor, and 24 (21.13%) of these patients developed anastomotic leak. Of these 24 patients, 13 (54.16%) have been treated with a metallic stent and 11 (45.84%) without a stent. The average age of the patients was 55.69 and 62.45 years, respectively. All patients treated with and without a stent have been males. Eight (61.5%) stents were placed in the neck and five (38.5%) in the chest. However, among the 11 fistulas treated without a stent, 9 patients had cervical anastomosis (81.81%) and 2 patients (18.18%) had anastomosis in the chest. Twelve patients (92.30%) with a stent preserve digestive continuity, and 10 patients (90.90%) were treated without a stent. One patient died in the stent group and one in the nonstent group. The treatment with metallic stent of the anastomotic leak after esophagectomy is an option that can prevent reoperation in these patients, but it does not decrease the average of the hospital stay. The stent may be more useful in thoracic anastomotic leaks.

Abstract
Upper gastrointestinal (GI) stents are increasingly being used to manage upper GI obstructions. Initially developed for palliative treatment of esophageal cancer, upper GI stents now play an emerging role in benign strictures of the upper GI tract. Because recurrent obstruction and stent-related complications are common, new modifications of stents have been implemented. Self-expandable metal stents (SEMS) have replaced older plastic stents. In addition, newly designed SEMS have been developed to prevent complications. This review provides an overview of the various types, indications, methods, complications, and clinical outcomes of upper GI stents in a number of malignant and benign disorders dividing the esophagus and gastroduodenum.

Abstract
Oesophageal stenting is now standard treatment for managing both benign and malignant stenosis of the oesophagus. There is a wide choice in oesophageal stents currently available on the market, with variations in the stent material, size and design. Most oesophageal stents are made from metal alloy compounds for use in malignant strictures, although there are stents made of durable polymers, and now of biodegradable (BD) material, for use in both benign and malignant strictures. With the development of self-expanding plastic stents, self-expanding metal stents and BD stents, stent placement for oesophageal pathologies can be safe and cost-effective. Oesophageal stenting has several challenges for a therapeutic endoscopist which is determined by the location of stricture or tumour, the anatomy of the stenosis and the nature of stent selected. Strictures that have narrow or tortuous lumens can be particularly difficult to stent as the luminal diameter must allow access of at least a 0.035 inch guide wire. This review covers the indications and outcomes of different stents in clinical situations to help rational decision-making.

Abstract
BACKGROUND The majority of currently available oesophageal metal stents are partially covered to reduce migration risk. Preliminary experiences with fully covered stents seem to indicate an increased risk of migration in patients treated for malignant dysphagia. The aim of our study was to determine, in this setting, the safety and efficacy of a new, recently introduced stent with anti-migration proprieties. METHODS We designed a prospective, multicentre, non-randomized, follow-up study in nine tertiary referral centres. Eighty-two patients with dysphagia due to inoperable or metastatic oesophageal cancer were included. In all of them the fully covered WallFlex(®) stent was placed. Main outcome measurements included functional outcome, recurrent dysphagia, complications, and mortality. RESULTS Dysphagia score improved from a median of 3, before stenting, to 1 at 4 weeks after stent placement (P<0.001). Perforation occurred in 1 patient after 39 days, while bleeding was reported in 3. In total, 19 patients (23.1%) developed recurrent dysphagia because of stent migration (N=10, 12.2%), tissue overgrowth (N=7; 8.5%), and food impaction (N=2; 2.4%). CONCLUSIONS Placement of the fully covered WallFlex(®) stent resulted in safe and effective palliation of malignant dysphagia, with migration and tissue overgrowth rates comparable to previously reported data on partially covered stents.

Abstract
BACKGROUND Most patients with oesophageal and gastro-oesophageal carcinoma are diagnosed at an advanced stage and require palliative intervention. Although there are many kinds of interventions, the optimal one for the palliation of dysphagia remains unclear. This review updates the previous version published in 2009. OBJECTIVES The aim of this review was to systematically analyse and summarise the efficacy of different interventions used in the palliation of dysphagia in primary oesophageal and gastro-oesophageal carcinoma. SEARCH METHODS To find new studies for this updated review, in January 2014 we searched, according to the Cochrane Upper Gastrointestinal and Pancreatic Diseases model, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE and CINAHL; and major conference proceedings (up to January 2014). SELECTION CRITERIA Only randomised controlled trials (RCTs) were included in which patients with inoperable or unresectable primary oesophageal cancer underwent palliative treatment. Different interventions like rigid plastic intubation, self-expanding metallic stent (SEMS) insertion, brachytherapy, external beam radiotherapy, chemotherapy, oesophageal bypass surgery, chemical and thermal ablation therapy, either head-to-head or in combination, were included. The primary outcome was dysphagia improvement. Secondary outcomes included recurrent dysphagia, technical success, procedure related mortality, 30-day mortality, adverse effects and quality of life. DATA COLLECTION AND ANALYSIS Data collection and analysis were performed in accordance with the methods of the Cochrane Upper Gastrointestinal and Pancreatic Diseases Review Group. MAIN RESULTS We included 3684 patients from 53 studies. SEMS insertion was safer and more effective than plastic tube insertion. Thermal and chemical ablative therapy provided comparable dysphagia palliation but had an increased requirement for re-interventions and for adverse effects. Anti-reflux stents provided comparable dysphagia palliation to conventional metal stents. Some anti-reflux stents might have reduced gastro-oesophageal reflux and complications. Newly-designed double-layered nitinol (Niti-S) stents were preferable due to longer survival time and fewer complications compared to simple Niti-S stents. Brachytherapy might be a suitable alternative to SEMS in providing a survival advantage and possibly a better quality of life, and might provide better results when combined with argon plasma coagulation or external beam radiation therapy. AUTHORS' CONCLUSIONS Self-expanding metal stent insertion is safe, effective and quicker in palliating dysphagia compared to other modalities. However, high-dose intraluminal brachytherapy is a suitable alternative and might provide additional survival benefit with a better quality of life. Some anti-reflux stents and newly-designed stents lead to longer survival and fewer complications compared to conventional stents. Combinations of brachytherapy with self-expanding metal stent insertion or radiotherapy are preferable due to the reduced requirement for re-interventions. Rigid plastic tube insertion, dilatation alone or in combination with other modalities, and chemotherapy alone are not recommended for palliation of dysphagia due to a high incidence of delayed complications and recurrent dysphagia.

Abstract
Gastroesophageal junction cancer has an increasing incidence in western countries. It is inoperable when first manifested in more than 50% of cases. So, palliation is the only therapeutic option for the advanced disease to relieve dysphagia and its consequences in weakened patients with an estimated mean survival under 6 mo. This article has tried to identify trends focusing on current information about the best palliative treatment, with an emphasis on the role of stenting. Self-expanding stent placement, either metal or plastic, is the main management option. However, this anatomical location creates some particular problems for stent safety and effectiveness which may be overcome by properly designed novel stents. The stents ensure a good quality of life and must be preferred over other alternative methods of loco-regional modalities, i.e., external radiation, laser thermal or photodynamic therapy. Although stent placement is generally a simple, safe and effective method, there are sometimes complications, increasing the morbidity and mortality rate. Bypass operative procedures have now been abandoned as a first choice. The stomach instead of the colon must be used for a bypass operation when it is needed. Chemotherapy, despite the toxicity, and intraluminal radiation (brachytherapy) have a well-defined role.

Abstract
Endoscopic stents have evolved dramatically over the past 20 years. With the introduction of uncovered self-expanding metal stents in the early 1990s, they are primarily used to palliate symptoms of malignant obstruction in patients with inoperable gastrointestinal (GI) cancer. At present, stents have emerged as an effective, safe, and less invasive alternative for the treatment of malignant GI obstruction. Clinical decisions about stent placement should be made based on the exact understanding of the patient's condition. These recommendations based on a critical review of the available data and expert consensus are made for the purpose of providing endoscopists with information about stent placement. These can be helpful for management of patients with inoperable cancer or various nonmalignant conditions in the upper GI tract.

Abstract
Endoscopic stent placement is an effective palliative treatment for malignant dysphagia and fistula, leading to rapid symptom relief. However, recurrent dysphagia and other stent-related complications are common, for which reason continuously new design modifications are implemented. Although some of these changes facilitate stent placement, complications remain and occur at similar rates. Recently, stents have also been used in benign esophageal disorders. Covered stents have the ability to effectively seal esophageal perforations and leaks, reducing the need for invasive surgery. This benefit does not pertain to patients with refractory benign esophageal strictures, in whom stents have limited long-term effect and are associated with a high complication rate. The initial results of fully covered metal stents in refractory esophageal variceal bleeding are encouraging, but their definite role remains to be further elucidated. This review provides an overview of indications, techniques, and management of complications of stents in malignant and benign esophageal disease.

Abstract
BACKGROUND Fully covered self-expanding metal stents (FCSEMS), unlike partially covered SEMS (PCSEMS), have been used to treat benign as well as malignant conditions. We aimed to evaluate the outcome of PCSEMS and FCSEMS in patients with both benign and malignant esophageal diseases. METHODS Data were reviewed of all patients who underwent SEMS placement for malignant or benign conditions between January 1995 and January 2012. Patients with cancer were followed for at least 3 months, until death or surgery. Patients with benign conditions had stents removed between 4 and 12 weeks. Patient demographics, location and type of lesion, stent placement and removal, clinical success, and adverse events were analyzed. RESULTS A total of 252 patients (mean ± standard deviation age 68.5 ± 14 years; 171 male) received 321 SEMS (209 PCSEMS, 112 FCSEMS) for malignant (78 %) and benign (22 %) conditions. Stent placement and removal was successful in 97.6 and 95.6 % procedures. Successful relief of malignant dysphagia was noted in 140 of 167 patients (83.8 %) and control of benign fistulas, leaks, and perforations was noted in 21 of 25 patients (84 %), but only 8 of 15 patients (53 %) with recalcitrant benign strictures had effective treatment. Fifty-six patients (22.2 %) experienced at least one stent-related adverse events. Migration was frequent, occurring in 61 of 321 stent placements (19 %), and more frequently with FCSEMS than PCSEMS (37.5 vs. 9.1 %, p < 0.001). FCSEMS, benign conditions, and distal location were the variables independently associated with migration (p < 0.001, p = 0.022, and p = 0.008). Patients with PCSEMS were more likely to have tissue in- or overgrowth than FCSEMS (53.4 vs. 29.1 %, p = 0.004). CONCLUSIONS Both PCSEMS and FCSEMS can be used in benign and malignant conditions; they are both effective for relieving malignant dysphagia and for closing leaks and perforations, but they seem less effective for relieving benign recalcitrant strictures. Stent migration is more common with FCSEMS, which may limit its use for the palliation of malignant dysphagia.

Abstract
In recent years, the number of quality-of-life (QOL) studies on patients with esophageal cancer has increased; however, the number of studies related to the effects of self-care education programs on QOL of these patients is scarce. This article reports on the effects of a self-care education program on QOL for patients with esophageal cancer in Babol, Iran. The quasi-experimental study had a convenience sample of 105 patients with esophageal cancer referred to oncology centers in Babol City. A quasi-random allocation technique was used to divide the sample into experimental (n = 55) and control (n = 50) groups. Appropriate instruments were used to measure QOL (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-30 and Quality of Life Questionnaire-Oesophageal 18). Questionnaires were completed by the respondents before and 3 months after implementing the educational program that consisted of group discussion, lectures, and pamphlets. There was no significant difference between QOL mean score of both groups before the intervention; however, after implementing the educational program, the QOL significantly improved in the experimental group (p = .001), whereas QOL decreased in the controls. We conclude that self-care education programs have positive effects on the QOL of patients with esophageal cancer. Planning and implementing such self-care education programs, when patients are under treatment, can help them improve their QOL.

Abstract
Esophageal stenting with self-expanding plastic or covered metal stents is believed to be safe and effective. As data on the outcome of patients with long-term stenting are not available, this study was conducted to evaluate the safety and efficacy of long-term esophageal stenting. From 2002 to 2008, 70 patients with long-term esophageal stenting for various indications from a prospective database were included into further analysis. The median stent period was 297 (124-1980) days during a mean follow-up time of 55 ± 52.4 months. Overall complication rate was 30% with a primary success rate of 97.2%. The stent-related total reintervention rate was 17.1%. There were no correlations between stent characteristics and the risk of complication or migration. No stent-related death was observed. Our data provide evidence that long-period esophageal stenting is safe and effective for various indications.

Abstract
Background Benign esophageal ruptures and anastomotic leaks are life-threatening conditions that are often treated surgically. Recently, placement of partially and fully covered metal or plastic stents has emerged as a minimally invasive treatment option. We aimed to determine the clinical effectiveness of covered stent placement for the treatment of esophageal ruptures and anastomotic leaks with special emphasis on different stent designs. Methods Consecutive patients who underwent placement of a fully covered self-expandable metal stent (FSEMS), a partially covered SEMS (PSEMS) or a self-expanding plastic stent (SEPS) for a benign esophageal rupture or anastomotic leak after upper gastrointestinal surgery in the period 2007-2010 were included. Data on patient demographics, type of lesion, stent placement and removal, clinical success and complications were collected Results A total of 52 patients received 83 esophageal stents (61 PSEMS, 15 FSEMS, 7 SEPS) for an anastomotic leak (n = 32), iatrogenic rupture (n = 13), Boerhaave's syndrome (n = 4) or other cause (n = 3). Endoscopic stent removal was successful in all but eight patients treated with a PSEMS due to tissue ingrowth. Clinical success was achieved in 34 (76%, intention-to-treat: 65%) patients (PSEMS: 73%, FSEMS: 83%, SEPS: 83%) after a median of 1 (range 1-5) stent and a median stenting time of 39 (range 7-120) days. In total, 33 complications in 24 (46%) patients occurred (tissue in- or overgrowth (n = 8), stent migration (n = 10), ruptured stent cover (all Ultraflex; n = 6), food obstruction (n = 3), severe pain (n = 2), esophageal rupture (n = 2), hemorrhage (n = 2)). One (2%) patient died of a stent-related cause. Conclusions Covered stents placed for a period of 5-6 weeks may well be an alternative to surgery for treating benign esophageal ruptures or anastomotic leaks. As efficacy between PSEMS, FSEMS and SEPS is not different, stent choice should depend on expected risks of stent migration (SEPS and FSEMS) and tissue in- or overgrowth (PSEMS).

Abstract
Placement of removable stents to close pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy has not been reported before. This case presents the feasibility of removable esophageal stent in closing pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy for laryngeal cancer. Consecutive patients who underwent placement of removable esophageal stent for closing pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy for laryngeal cancer. Three patients underwent successful stent placement in the hypopharynx. The stents were well tolerated. Patient one had the stent for 14 months, leading to complete healing of the fistula. Removal was successful. The second patient was palliated but died 8 weeks after stent placement. The third patient has successful palliation of his tracheo-esophageal fistula and the stent is being exchanged every 3-4 months to palliate his fistula. Closure of pharyngo-cutaneous and tracheo-esophageal fistulas is feasible with esophageal removable stents. These stents provide alternative options when dealing with these challenging problems.

Abstract
BACKGROUND Fully covered esophageal self-expandable metallic stents (SEMS) often are used for palliation of malignant dysphagia. However, experience and data on these stents are still limited. The purpose of this multicenter study was to evaluate the efficacy and safety of fully covered nitinol SEMS in patients with malignant dysphagia. METHODS 37 patients underwent placement of a SEMS during a 3 year period. Five patients underwent SEMS placement as a bridge to surgery: one for tracheoesophageal fistula in the setting of squamous cell carcinoma of the esophagus, one for perforation in setting of esophageal adenocarcinoma, 27 for unresectable esophageal cancer (16 adenocarcinoma, 11 squamous cell carcinoma), two for lung cancer, and one for breast-cancer-related esophageal strictures. RESULTS SEMS placement was successful in all 37 patients. Immediate complications after stent deployment included chest pain (n = 6), severe heartburn (n = 1), and upper gastrointestinal bleeding requiring SEMS revision (n = 1). Dysphagia scores improved significantly from 3.2 ± 0.4 before stent placement to 1.4 ± 1.0 at 1 month (P < 0.0001), 1.1 ± 1.2 (P < 0.0001) at 3 months, and 1.3 ± 1.4 (P = 0.0018) at 6 months. The stent was removed in 11 patients (30%) for the following indications: resolution of stricture (n = 3), stent malfunction (n = 5), and stent migration (n = 3). After stent removal, three patients were restented, three underwent dilation, and two underwent PEG placement. Mean survival for the 37 patients after stent placement was 146.3 ± 143.6 (range, 13-680) days. CONCLUSIONS Our study suggests that fully covered SEMS placement improve dysphagia scores in patients with malignant strictures, particularly in the unresectable population. Further technical improvements in design to minimize long-term malfunction and migration are required.

Abstract
Successful palliation of dysphagia in patients with inoperable esophageal carcinoma has a major effect on quality of life. Self-expanding metal stents (SEMS) are currently recommended for rapid symptomatic relief when life expectancy is less than 3 months. We assessed complication and reintervention rates along with survival outcomes in patients with inoperable esophageal carcinoma undergoing stent insertion. A retrospective audit was performed from April 2007 to June 2009 for all inoperable primary esophageal carcinoma patients who had an esophageal stent inserted for dysphagia. Case notes were reviewed for clinical, pathological, stent and complication details, while ICD-10 causes of death were obtained from the Department of Health and Social Services, Northern Ireland. Fifty-six stents were inserted into 53 patients (66.0% male, mean age of 70 years). Inoperability was defined by metastatic spread (n= 34, 64.2%), locally advanced disease (n= 7, 13.2%), and severe medical comorbidities (n= 12, 22.6%). The median time from diagnosis to stent insertion was 109 (interquartile range [IQR] 43-187) days. Fifty stents (94.3%) were successfully deployed, while three patients (5.7%) required an additional stent as the primary stent had not bridged the tumor (proximal deployment = 2, suboptimal stent length = 1). Post-SEMS dysphagia scores were significantly better than pre-SEMS scores (2.90 vs. 1.54, P < 0.001). There were 27 complications identified in 23 (43.4%) patients (major complications = 9, minor complications = 14). Twelve patients (22.6%) required additional endoscopic procedures. The 30-day mortality rate was 11.3% (n= 6). Only one patient (1.9%) remains alive with a cumulative median survival rate of 84 (IQR 38-156) days. Esophageal stent insertion in this group of patients still presents a clinical challenge, with complication and endoscopic reintervention rates of 43.4 and 22.6%, respectively. Our results are comparable with previously published series, and as a palliative modality stent insertion remains appropriate when expected survival is less than 3 months. A range of SEMS is currently available with broadly similar efficacy and safety profiles. Data regarding the newly available fully covered SEMS suggest that they should be avoided.

Abstract
Esophageal cancer is often diagnosed at an advanced stage, with many patients
found to have locoregional or metastatic disease at time of diagnosis. Because
of this, cure may be unlikely, leading treatment efforts to focus more on
symptom palliation and improving patient quality of life. The majority of
patients with advanced disease suffer from some degree of dysphagia. Palliative
efforts are therefore directed at relieving dysphagia, allowing patients to
manage their oropharyngeal secretions, reduce aspiration risk, and maintain
caloric intake orally. A variety of endoscopic treatment modalities have been
utilized with these objectives in mind, with options determined by the location
and size of the tumor, as well as the patient's expected prognosis. In this
article, we review the use of endoscopically-placed stents for palliation in
patients with advanced esophageal cancer. We discuss the history of stent use in
such cases, as well as more recent developments in stent technology. We give an
overview of some of the more commonly used stents in practice, discuss the
technique of insertion, and survey the short- and long-term outcomes of stent
placement.

Abstract
BACKGROUND Migration is the most common complication of the fully covered metallic self-expanding esophageal stent (SEMS). This study aimed to determine the potential preventive effect of proximal fixation on the mucosa by clips for patients treated with fully covered SEMS. METHODS In this study, 44 patients (25 males, 57%) were treated with fully covered SEMS including 22 patients with esophageal stricture (4 malignant obstructions, 6 anastomotic strictures, and 12 peptic strictures) and 22 patients with fistulas or perforations (10 anastomotic leaks, 4 perforations, and 8 postbariatric surgery fistulas). The Hanarostent (n = 25), Bonastent (n = 5), Niti-S (n = 12), and HV-stent (n = 2) with diameters of 18 to 22 mm and lengths of 80 to 170 mm were used. Two to four clips (mean, 2.35 ± 0.75 clips) were used consecutively in 23 patients to fix the upper flared end of the stent with the esophageal mucosal layer. Stent migration and its consequences were collected in the follow-up assessment with statistical analysis to compare the patients with and without clip placement. RESULTS No complication with clip placement was observed, and the retrieval of the stent was not unsettled by the persistence of at least one clip (12 cases). Stent migration was noted in 15 patients (34%) but in only in 3 of the 23 patients with clips (13%). The number of patients treated to prevent one stent migration was 2.23. The predictive positive value of nonmigration after placement of the clip was 87%. In the multivariate analysis, the fixation with clips was the unique independent factor for the prevention of stent migration (odds ratio, 2.3; 95% confidence interval, 0.10-0.01; p = 0.03). CONCLUSIONS Anchoring of the upper flare of the fully covered SEMS with the endoscopic clip is feasible and significantly reduces stent migration.

Abstract
Caustic strictures of the gastrointestinal tract are often difficult to treat, since relapses are frequent after medical or endoscopic treatment. Thus, novel approaches are needed. We report here our experience with self-expandable metallic stents (SEMS) as a new endoscopic approach in three patients with corrosive strictures of the upper gastrointestinal tract.

Abstract
BACKGROUND Placement of self-expanding metal stents (SEMS) or plastic stents (SEPS) has emerged as a minimally invasive treatment option for benign oesophageal ruptures and leaks; however, it is not clear which stent type should be preferred. AIM To assess clinical effectiveness and safety of treating benign oesophageal ruptures and anastomotic leaks with temporary placement of a stent with special emphasis on different stent designs. METHODS A pooled analysis was performed after searching PubMed and EMBASE databases for studies regarding placement of fully covered and partially covered SEMS (FSEMS and PSEMS) and SEPS for this indication. Data were pooled and evaluated for clinical outcome, complications and survival. RESULTS Twenty-five studies, including 267 patients with complete follow-up on outcome, were identified. Clinical success was achieved in 85% of patients and was not different between stent types (SEPS 84%, FSEMS 85% and PSEMS 86%, P = 0.97). Time of stent placement was longest for SEPS (8 weeks) followed by FSEMS and PSEMS (both 6 weeks). In total, 65 (34%) patients had a stent-related complication. Stent migration occurred more often with SEPS [n = 47 (31%)] and FSEMS [n = 7 (26%)] than with PSEMS [n = 2 (12%), P ≤ 0.001], whereas there was no significant difference in tissue in- and overgrowth between PSEMS [12% vs. 7% (FSEMS) and 3% (SEPS), P = 0.68]. CONCLUSIONS Although there is a lack of randomised controlled trials, it seems that covered stent placement for a period of 6-8 weeks is safe and effective for benign oesophageal ruptures and anastomotic leaks to heal. As efficacy between different stent types is not significantly different, stent choice should depend on expected risk of stent migration (self-expanding plastic stents and fully covered self-expanding metal stents) and, to a minor degree, on expected risk of tissue in- or overgrowth (partially covered self-expanding metal stents).

Abstract
OBJECTIVE Esophageal anastomotic leaks, perforations, and fistulae are associated with considerable morbidity and mortality. The aim of the present study was to assess the efficacy of self-expanding plastic stents in the treatment of esophageal leaks. METHODS From 2001 to 2009, 41 patients with postoperative anastomotic leaks (n = 30), esophageal perforations (n = 6), or fistulae (n = 5) were treated by endoscopic insertion of self-expanding plastic stents. The clinical outcome of the patients was analyzed, including leak healing, morbidity, and mortality. RESULTS Self-expanding plastic stents were successfully inserted in all 41 patients without procedure-related complications. Non-ventilated patients received oral feeding an average of 3.9 days after stent placement. Complete leak healing was obtained in 27 of 30 patients (90%) with anastomotic leaks and 5 patients (83%) with perforation. Sealing of fistulae by the stents was achieved in all 5 patients, and closure of the fistula was observed in 2 patients (40%). The mean healing time was 30 days for anastomotic leaks, 15 days for esophageal perforations, and 16 days for fistulae. Stent migration occurred in 14 cases, but endoscopic reintervention and new stent placement were successful in all cases. In-hospital mortality after treatment of esophageal leaks with stents was 10%. CONCLUSIONS In combination with effective interventional or surgical drainage, stenting is a viable option for the treatment of esophageal anastomotic leaks and perforations, but the success in tracheoesophageal fistula is limited.

Abstract
Endoluminal stents are commonly used for palliative treatment of dysphagia in patients with advanced esophageal malignancies. The most frequently used esophageal stents are self-expanding metal stents. Removable self-expanding plastic stents have recently been used in the management of esophageal cancer patients treated with curative intent. Esophageal stents effectively alleviate dysphagia in most patients, and stent placement is associated with a low rate of complications. This article reviews the use of self-expanding esophageal stents in patients with esophageal cancer. Nutrition considerations following stent placement are addressed.

Abstract
Self-expanding metal stents (SEMS) are used to treat obstructive malignancies of the esophagus or esophagogastric junction; however, a potential complication is recurrent dysphagia because of tissue in/overgrowth. The placement of a second SEMS is one strategy to re-establish patency of the esophageal lumen. We evaluated the safety and efficacy of an alternative and likely less costly approach: placing a self-expanding plastic stent (SEPS) to manage relapsing dysphagia in patients previously treated with a partially covered SEMS. From December 2007 to January 2009, 13 patients previously treated with a SEMS for malignant dysphagia underwent treatment by inserting a SEPS to palliate relapsing dysphagia, as a result of tissue in/overgrowth. Stenosis was located in the upper esophagus in one patient, in the middle in four patients, and in the lower esophagus in eight patients. Clinical evaluation was performed at the time of stent placement, after 1 week, and then, monthly until death. The SEPS was successfully placed in a single treatment session for all patients. No preliminary dilation was required, and no further treatment was necessary for any patient. Before stenting, the median dysphagia score was 4 (range 3-4), and 1 week later the score was 0 for all patients. The resolution of dysphagia persisted until patient death (from tumor progression). The mean survival after the SEPS insertion was 4 months (range 3-8). This case series supports the use of a SEPS to palliate dysphagia from tissue in/overgrowth of a SEMS. Future clinical trials with larger patient samples are warranted.

[PMID: 20003967 DOI: 10.1016/j.gie.2009.09.046] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2009] [Accepted: 09/25/2009] [Indexed: 02/08/2023]
Abstract
BACKGROUND Self-expanding metal stents are frequently used for the palliation of malignant dysphagia. Recently, a new stent design, the Evolution stent (Cook Medical, Limerick, Ireland), was developed. The stent has an internal and external silicone coating to resist tissue ingrowth and uncoated dual flanges on both ends to prevent migration. Its controlled-release system may allow full control and precise positioning of the stent. OBJECTIVE To determine the safety and clinical effectiveness of the Evolution stent for the palliation of dysphagia in patients with malignant strictures located in the esophagus (n = 33 [75%]) or gastric cardia (n = 11 [25%]). METHODS All patients who underwent placement of an esophageal Evolution stent from February to December 2008 received follow-up telephone calls 14 days after treatment and thereafter monthly until death. Data on technical and clinical outcome, complications, and recurrent dysphagia were collected. RESULTS A total of 44 patients (32 [73%] men, median age 74 years [range 48-91 years]) were treated with the Evolution stent. The median tumor length was 6 cm (range 1-11 cm). Stent placement was technically successful in 41 patients. Dysphagia improved from a median of 3 (ability to swallow liquids only) to 1 (ability to eat some solid foods) 4 weeks after stent placement. Major complications occurred in 4 (9%) patients, ie, pneumonia (3 patients) and hemorrhage (1 patient). Two (5%) patients died of pneumonia. Minor complications included gastroesophageal reflux and mild retrosternal pain in 11 (25%) and 4 (9%) patients, respectively. Recurrent dysphagia developed in 11 (25%) patients as a result of tissue ingrowth or overgrowth (6 patients; 14%), food impaction (3 patients; 7%), or stent migration (2 patients; 5%). CONCLUSIONS The Evolution stent is safe and effective for the palliation of dysphagia from esophageal and gastric cardia cancer. Randomized trials are needed to compare this device with other stent designs.

A new fully covered stent with antimigration properties for the palliation of malignant dysphagia: a prospective cohort study. Gastrointest Endosc 2010; 71:600-5. [PMID: 20003970 DOI: 10.1016/j.gie.2009.09.023] [Citation(s) in RCA: 63] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2009] [Accepted: 09/25/2009] [Indexed: 02/08/2023]
Abstract
BACKGROUND Fully covered stents are designed to resist tissue ingrowth that is often seen with partially covered stents. An issue with fully covered stents is the risk of migration. OBJECTIVE We aimed to determine efficacy, recurrent dysphagia, and complications of the SX-ELLA stent Esophageal HV, which is fully covered to resist tissue ingrowth and has an antimigration ring to withstand migration. DESIGN Prospective cohort study. SETTING Two tertiary referral centers. PATIENTS Forty-four patients with malignant esophageal strictures from inoperable or metastatic esophageal or gastric cardia cancer (n = 42) or lung cancer (n = 2). INTERVENTIONS Placement of an SX-ELLA stent. MAIN OUTCOME MEASURES Functional outcome, recurrent dysphagia, complications, and survival. RESULTS Dysphagia improved from a median score of 3 (liquids only) before stent placement to 1 (ability to eat some solid food) 4 weeks later (P < .001). Twelve of 44 (Kaplan Meier analysis = 40%) patients developed 18 episodes of recurrent dysphagia of which 6 were caused by stent migration and 2 by tissue overgrowth. In total, 14 episodes of major complications developed in 10 of 44 (Kaplan Meier analysis = 29%) patients, 8 of which were caused by hemorrhage. After a median follow-up of 15 months, 39 patients had died (median survival 110 days), 5 (11%) from hemorrhage. LIMITATIONS Nonrandomized study design. CONCLUSIONS Dysphagia caused by esophageal cancer can be successfully palliated by placement of a new, fully covered esophageal stent (SX-ELLA). Although this single-wire braided stent with an antimigration ring is supposed to be less traumatic and to reduce migration, this was not substantiated in this study. Further improvements of stent features are needed to achieve the goals set for this study.

Abstract
These recommendations provide an evidence-based approach to the role of esophageal stents in the management of benign and malignant diseases. These guidelines have been developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee and approved by the Board of Trustees. The following guidelines are based on a critical review of the available scientific literature on the topic identified in Medline and PubMed (January 1992-December 2008) using search terms that included stents, self-expandable metal stents, self-expandable plastic stents, esophageal cancer, esophageal adenocarcinoma, esophageal squamous cell carcinoma, esophageal stricture, perforations, anastomotic leaks, tracheoesophageal fistula, and achalasia. These guidelines are intended for use by health-care providers and apply to adult, but not pediatric, patients. As with other practice guidelines, these guidelines are not intended to replace clinical judgment but rather to provide general guidelines applicable to the majority of patients. Clinicians need to integrate recommendations with their own clinical judgment, and with individual patient circumstances, values, and preferences. They are intended to be flexible, in contrast to standards of care, which are inflexible policies designed to be followed in every case. Specific recommendations are based on relevant published information. The quality of evidence and strength of recommendations have been assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system, which is a system that has been adopted by multiple national and international societies. The GRADE system is based on a sequential assessment of quality of evidence, followed by assessment of the balance between benefits vs. downsides (harms, burden, and costs) and subsequent judgment regarding the strength of recommendation.

A fully-covered stent (Alimaxx-E) for the palliation of malignant dysphagia: a prospective follow-up study. Gastrointest Endosc 2009; 70:1082-9. [PMID: 19640521 DOI: 10.1016/j.gie.2009.05.032] [Citation(s) in RCA: 66] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2009] [Accepted: 05/21/2009] [Indexed: 02/08/2023]
Abstract
BACKGROUND The majority of the currently available metal stents are partially covered to reduce migration risk. However, one of the remaining issues is tissue ingrowth through the uncovered stent parts. OBJECTIVE To determine efficacy, recurrent dysphagia, and complications of a fully covered stent, ie, the Alimaxx-E stent, and to compare two stent delivery systems, ie, one introducing the stent over a guidewire and one introducing the stent over a small-caliber endoscope. DESIGN A prospective, follow-up study evaluating a new stent design, with randomization for type of introduction system. SETTING Three tertiary referral centers. PATIENTS Forty-five patients with inoperable or metastatic esophageal or gastric cardia cancer. INTERVENTIONS Stent placement. MAIN OUTCOME MEASUREMENTS (1) Functional outcome, recurrent dysphagia, complications, and mortality of the Alimaxx-E stent; (2) functional aspects of the delivery system. RESULTS At 4 weeks after stent placement, the dysphagia score improved in all patients (P < .001). Twenty-two of 45 patients (49%) developed among them 28 episodes of recurrent dysphagia, predominantly stent migration (n = 16). Major complications occurred in 9 of 45 patients (20%), with all 5 early (<1 week) complications (severe pain [n = 3], hemorrhage [n = 1], and fever [n = 1]) occurring in patients in whom the stent was introduced over the endoscope (P = .02). During follow-up, 44 patients died, 3 (7%) from hemorrhage. LIMITATION The Alimaxx-E stent was not randomly compared with other stent designs. CONCLUSIONS Placement of Alimaxx-E stents is safe and produces long-term relief of dysphagia, particularly when introduced over a guidewire. The migration rate of the Alimaxx-E stent is, however, unacceptably high, and an adapted stent design is needed.

Gastrointest Endosc 2009; 70:614-9. [PMID: 19539918 DOI: 10.1016/j.gie.2009.01.026] [Citation(s) in RCA: 63] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2008] [Accepted: 01/15/2009] [Indexed: 12/24/2022]
Abstract
BACKGROUND Patients with locally advanced esophageal cancer who require neoadjuvant therapy have significant dysphagia. OBJECTIVES To prospectively evaluate Polyflex stents to treat malignant dysphagia and to ameliorate weight loss in patients with locally advanced esophageal cancer who will undergo neoadjuvant therapy. DESIGN A prospective nonrandomized study. SETTING Tertiary-referral cancer center. PATIENTS Thirteen patients with esophageal cancer (11 adenocarcinoma, 2 squamous-cell carcinoma). All patients were men, with a mean age of 63 years. INTERVENTIONS EUS followed by stent placement. MAIN OUTCOME MEASUREMENTS Dysphagia scores and patient weights. RESULTS There were no perforations and no episodes of bleeding. Immediate complications included chest discomfort in 12 of 13 patients. The mean dysphagia score at the time of stent placement was 3. Mean dysphagia scores obtained at 1, 2, 3, and 4 weeks after stent placement were 1.1 (P = .005), 0.8 (P = .01), 0.9 (P = .02), and 1.0 (P = .008), respectively. Stent migration occurred at some point in 6 of 13 patients (46%). LIMITATIONS A single center and small size of study. CONCLUSIONS Simultaneous EUS staging and Polyflex stent placement is safe and allows oral feeding during neoadjuvant therapy. Dysphagia scores improved in a statistically significant manner. Stent migration was a common event, although not all patients with a migrated stent will require stent replacement, because migration may be a sign of tumor response to neoadjuvant therapy.
