Abstract
The treatment of caustic esophageal strictures is a challenging topic. Although traditional therapies have limited efficacy, most of these patients eventually require surgery. Biodegradable (BD) stents are newly designed stents for benign conditions. This is a retrospective case series of seven patients with caustic esophageal stricture. BD esophageal stents were inserted for palliation of dysphagia. The position of the stent was checked at 1, 4, 8, 12 16, 20, and 24 weeks and at the end of follow-up period. The follow-up period was 60 ± 23 (36-102) weeks. Complete dissolution of the stent occurred at 16 ± 4 (12-20) weeks. Three patients had partial/complete relief of dysphagia. The remaining four patients experienced tissue hyperplasia at the edges of the stent and required serial dilations. At the end of follow-up, all patients had partial or complete relief of dysphagia. Although BD stents have some efficiency, tissue hyperplasia is the main limiting factor. Further randomized trials are needed to determine efficiency of BD stents for caustic damage.

A retrospective analysis of early and late outcome of biodegradable stent placement in the management of refractory anastomotic colorectal strictures. Surg Endosc 2013; 27:2487-91.

Abstract
BACKGROUND Benign colorectal strictures are treated conventionally by endoscopic dilation. Experience using SEMS for benign colonic strictures is limited, and outcomes to date have been disappointing. Refractory colorectal strictures remain challenging to be treated with surgery. Polydioxanone-based stent are biodegradable (BD) stent CE approved for esophageal strictures. This study was designed to investigate retrospectively the safety and the efficacy of these stents for the management of strictures refractory to multiple sessions of dilation. METHODS Patients with postsurgical benign strictures located within 20 cm from anal verge, refractory to mechanical or pneumatic dilation (at least 3 sessions) were included in this analysis. Clinical success was defined as the absence of occlusive symptoms and the ability to pass through the stricture with a regular size colonoscope. All patients were predilated before stent placement. Stents were released under fluoroscopic control. All patients were under stool softeners for 3 months. Follow-up was scheduled with endoscopic and fluoroscopic controls within 90 days from stent deployment and afterwards by telephone interview and/or ambulatory consultation. RESULTS Eleven patients (7 males, mean age 62.3 ± 8.5 years) were included. Technical success was achieved in all the patients. Stent migration was observed in four patients within the first 2 weeks after stent placement. Stent migration was followed by recurrence of stricture and obstructive symptoms in all the cases. Among the seven patients who completed the process of stent biodegradation, five of them had complete resolution of the stricture and relief of symptoms. Two of 11 patients required surgical treatment during the follow-up period (mean 19.8 (range 42-15) months). The overall success rate of the BD stent was 45 %. CONCLUSIONS This retrospective analysis of a limited number of patients demonstrated that nondedicated esophageal BD stents are associated with high risk of migration and clinical success in less than 50 % of patients. Dedicated stents with large diameter and antimigration findings could potentially improve the outcome of patients with refractory benign colorectal strictures.

Abstract
BACKGROUND Temporary placement of self-expandable stents has been increasingly used for the management of benign esophageal diseases. OBJECTIVE To evaluate the safety of endoscopic removal of esophageal self-expandable stents placed for the treatment of benign esophageal diseases. DESIGN Multicenter retrospective study. SETTING Six tertiary care centers in the United States and Europe. PATIENTS A total of 214 patients with benign esophageal diseases undergoing endoscopic stent removal. INTERVENTION Endoscopic stent removal. MAIN OUTCOME MEASUREMENTS Endoscopic techniques for stent removal, time to stent removal, and adverse events related to stent removal. RESULTS A total of 214 patients underwent a total of 329 stent extractions. Stents were mainly placed for refractory strictures (49.2%) and fistulae (49.8%). Of the removed stents, 52% were fully covered self-expandable metal stents (FCSEMSs), 28.6% were partially covered self-expandable metal stents (PCSEMSs), and 19.5% were self-expandable plastic stents. A total of 35 (10.6%) procedure-related adverse events were reported, including 7 (2.1%) major adverse events. Multivariate analysis revealed that use of PCSEMSs (P < .001) was a risk factor for adverse events during stent removal. Favorable factors for successful stent removal were FCSEMSs (P ≤ .012) and stent migration (P = .010). No significant associations were found for stent indwelling time (P = .145) and stent embedding (P = .194). LIMITATIONS Retrospective analysis, only tertiary care centers. CONCLUSIONS With an acceptable major adverse event rate of 2.1%, esophageal stent removal in the setting of benign disease was found to be a safe and feasible procedure. FCSEMSs were more successfully removed than self-expandable plastic stents and PCSEMSs. Adverse events caused by stent removal were not time dependent.

Abstract
BACKGROUND Fully covered self-expandable metal stents (FCSEMSs) are increasingly being used for malignant and benign strictures. Particularly in the latter, FCSEMSs are known for their high migration rates. A new FCSEMS with a dog-bone shape and internal covering was developed to reduce migration risk. OBJECTIVE To evaluate recurrent dysphagia and safety of the new FC stent in benign and malignant esophageal disorders. DESIGN Prospective follow-up study. SETTING Tertiary referral center. PATIENTS Between November 2009 and February 2011, 48 consecutive patients (mean age 61 years, range 28-81 years) underwent FC stent placement for malignant (n = 33) or benign (n = 15) dysphagia. INTERVENTION FC stent placement. MAIN OUTCOME MEASUREMENTS Recurrent dysphagia and complications. RESULTS Indications for FC stent placement included esophageal cancer (n = 28), extrinsic malignant compression (n = 4), recurrent malignancy after esophagectomy (n = 1), and refractory benign esophageal stricture (n = 15). In malignant strictures, recurrent dysphagia occurred in 5 patients (15%) because of stent migration (n = 3), tissue overgrowth (n = 1), and acute edema (n = 1). In benign strictures, stents were prematurely removed in 9 (60%) patients because of stent migration (n = 5), tissue overgrowth (n = 3), and pain (n = 1). Recurrent dysphagia occurred in all patients after stent removal. Major complications occurred in 10 patients (30%) with malignant strictures and in 3 patients (20%) with benign strictures and included severe pain and/or vomiting (n = 8), fistula formation (n = 2), bleeding (n = 2), and aspiration pneumonia (n = 1). LIMITATION Nonrandomized study design. CONCLUSION Although the new FC stent effectively treats malignant dysphagia, it is associated with substantial major complications. In patients with refractory benign esophageal strictures, recurrent dysphagia occurs rapidly after removal of the new FC stent.

Abstract
The use of stents for esophageal strictures has evolved rapidly over the past 10 years, from rigid plastic tubes to flexible self-expanding metal (SEMS), plastic (SEPS) and biodegradable stents. For the palliative treatment of malignant dysphagia both SEMS and SEPS effectively provide a rapid relief of dysphagia. SEMS are preferred over SEPS, as randomized controlled trials have shown more technical difficulties and late migration with plastic stents. Despite specific characteristics of recently developed stents, recurrent dysphagia due to food impaction, tumoral and nontumoral tissue overgrowth, or stent migration, remain a major challenge. The efficacy of stents with an antireflux valve for patients with distal esophageal cancer varies between different stent designs. Concurrent treatment with chemotherapy and/or radiotherapy seems to be safe and effective. In the future, it can be expected that removable stents will be used as a bridge to surgery to maintain luminal patency during neoadjuvant treatment. For benign strictures, new stent designs, such as fully covered SEMS and biodegradable stents, may potentially reduce complications during stent removal.

Abstract
BACKGROUND Esophageal strictures are a common sequela of chemoradiation and/or surgery to the head and neck cancers and can lead to stenosis and significant dysphagia. Endoscopic dilation endoscopic and placement of self-expanding stents are often to used relieve dysphagia symptoms. However, these stents are not without risks and complications. METHODS We present a case of a 58-year-old man who had the rare complication of cervical osteomyelitis as a result of plastic esophageal stent placement for palliation of chemoradiation-induced strictures. RESULTS The patient was successfully managed with immobilization of the cervical spine in a halo vest and appropriate antibiotics. CONCLUSION To the best of our knowledge, this is the first reported case of cervical spine osteomyelitis after self-expanding plastic stent (SEPS) placement for esophageal stricture. It was successfully treated with immobilization and antibiotic therapy. The treating physician should be aware of this rare complication to make an early diagnosis. Literature on esophageal stent-induced cervical osteomyelitis is reviewed.

Abstract
Esophageal strictures are a common problem in gastroenterological practice. In general, the management of malignant or benign esophageal strictures is different and requires a different treatment approach. In daily clinical practice, stent placement is a commonly used modality for the palliation of incurable malignant strictures causing dysphagia, whereas, if available, intraluminal brachytherapy can be considered in patients with a good performance status. Recurrent dysphagia frequently occurs in malignant cases. In case of tissue in- or overgrowth, a second stent is placed. If stent migration occurs, the stent can be repositioned or a second (preferably partially covered) stent can be placed. Food obstruction of the stent lumen can be resolved by endoscopic cleansing. The cornerstone of the management of benign strictures is still dilation therapy (Savary-Gilliard bougie or balloon). There are a subgroup of strictures that are refractory or recur and an alternative approach is required. In order to prevent stricture recurrence, steroid injections into the stricture followed by dilation can be considered. In case of anastomotic strictures or Schatzki rings, incisional therapy is a safe method in experienced hands. Temporary stent placement is a third option before considering self-bougienage or surgery as a salvage treatment. In this review, the most frequently used endoscopic treatment modalities for malignant and benign stricture management will be discussed based on the available literature, and some practical information for the management in daily clinical practice will be provided.

Abstract
BACKGROUND & AIMS It is a challenge to manage refractory benign esophageal strictures (RBES). We compared the efficacy and safety of self-expanding plastic stents (SEPSs) with placement of biodegradable stents for the treatment of RBES. METHODS We studied 2 groups of consecutive patients with RBES who received temporary placement (6 weeks) of SEPSs (n = 20) or biodegradable stents (n = 18). Data were collected with respect to clinical outcome, complications, recurrent dysphagia, and reinterventions. RESULTS SEPSs were removed in 16 (80%) patients. Stent placement was not successful in 1 patient, while stent removal was not performed in another 3 patients. Six (30%) patients with an SEPS were dysphagia-free after a median follow-up of 385 days (range, 77-924 days). Ten (50%) developed recurrent dysphagia. Major complications occurred in 2 patients (10%; 1 with hemorrhage and 1 with perforation). Six patients (33%) with a biodegradable stent were dysphagia-free after a median follow-up of 166 days (range 21-559 days) (P = .83 compared with SEPS). Twelve patients (67%) had recurrent dysphagia. Major complications occurred in 4 patients (22%; 2 with hemorrhage, 2 with severe retrosternal pain) with a biodegradable stent (P = .30 compared with SEPS). Reinterventions were less frequently indicated after biodegradeble stent than after SEPS placement (15 [mean, 0.8 ± 0.6 per stent placed] vs 21 [mean, 1.3 ± 0.4 per stent placed], respectively; P = .03). CONCLUSIONS Placement of SEPSs or biodegradable stents provides long-term relief of dysphagia in 30% and 33%, respectively, of patients with RBES. Biodegradable stents require fewer procedures than SEPSs, offering an advantage. Although stent placement is a viable strategy in patients with RBES, the ideal strategy still needs to be defined.

Abstract
Partially covered self-expandable esophageal stents have been associated with unacceptable complications when used for benign esophageal disorders. With the introduction of removable or potentially removable fully covered stents and biodegradable stents, interest in using expandable stents for benign indications has been revived. Although expandable stents can offer a minimally invasive alternative to surgery, they can be associated with serious complications; hence, this approach should be considered in carefully selected patients, preferably on a protocol basis.

Abstract
BACKGROUND Self-expandable metals stents (SEMSs) have increasingly been used as a temporary device to bridge chemoradiotherapy in patients with malignant esophageal disease or in patients with benign esophageal defects or stenosis. OBJECTIVE To evaluate the outcome of removal of SEMSs in a large cohort of patients with benign and malignant esophageal disease. DESIGN Observational study with standardized treatment and follow-up. SETTING Single university center. PATIENTS Between 2001 and 2010, 95 consecutive patients referred for endoscopic SEMS extraction were included. INTERVENTIONS Endoscopic stent removal. MAIN OUTCOME MEASUREMENTS Technical and functional outcome and complications. RESULTS A total of 124 stent extractions were undertaken in 95 patients; both partially covered (68%) and fully covered (32%) SEMSs were removed. Three patients had 2 overlapping SEMSs in place. Successful primary removal was achieved in 89%; the secondary removal rate was 96%. Uncomplicated primary removal rate was significantly higher for fully covered versus partially covered stents (P = .035) and for single versus overlapping stents (P = .033). Patients with a complicated stent removal had the stent in place significantly longer compared with patients with an uncomplicated primary stent removal (126 days vs 28 days; P = .01). Surgical removal was required in 3 patients (2.4%). Six moderate and severe complications (5%) related to the endoscopic extraction occurred. LIMITATIONS Retrospective, nonrandomized study design. CONCLUSIONS Primary endoscopic removal of an SEMS is feasible in the majority of patients with benign and malignant esophageal disease. A longer time that a stent is in place and the use of partially covered SEMSs both impede removal. Moreover, overlapping SEMSs should be avoided for temporary use because stent disintegration and subsequent complications may occur.

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
BACKGROUND Fully covered esophageal self-expandable metal stents (FCSEMSs) are thought to induce less mucosal hyperplasia and are potentially removable. They may constitute an attractive alternative for the treatment of benign esophageal diseases. OBJECTIVE To evaluate the efficacy and safety of FCSEMSs in the treatment of benign esophageal diseases. DESIGN Patients referred for management of benign esophageal disease underwent placement of an FCSEMS and were entered into a prospective database and analyzed retrospectively for clinical response, efficacy, and morbidity. SETTING Two tertiary care centers with long-standing experience in the management of benign esophageal strictures. PATIENTS Between January 2006 and September 2007, 35 patients (mean age 61 years, range 20-85 years) underwent FCSEMS placement for benign esophageal diseases at 2 tertiary academic medical centers. There were 19 patients with benign esophageal strictures and 16 patients with leaks/perforations. INTERVENTION Temporary placement of FCSEMS until stricture resolution. MAIN OUTCOME MEASUREMENTS Clinical response, efficacy, and morbidity. RESULTS Indications for stent placement were esophageal leak/fistulae (n = 12), refractory benign strictures (n = 10), anastomotic strictures (n = 7), perforations (n = 4), and radiation-induced strictures (n = 2). Immediate complications were chest pain (2 patients), stent migration (2 patients), dysphagia (1 patient), respiratory compromise (1 patient), and arrhythmia (1 patient). Long-term complications included recurrent dysphagia (6 patients), aspiration pneumonia (2 patients), globus sensation (2 patients), abdominal pain (2 patients), and fever (1 patient). Stent migration was observed in 12 patients (34%). After placement, dysphagia scores at 1 month improved significantly from 3.1 ± 1.0 to 1.2 ± 1.3 (P < .0001). A total of 11 of 35 patients (31%) were treated successfully. Specifically, 21% of patients with refractory strictures and 44% of patients with leaks/fistulae had successful long-term outcomes without any need for reinterventions. All stents were retrieved successfully, except for 1 stent, which fractured and was retrieved in 2 pieces without any complications. CONCLUSION Use of FCSEMSs for benign esophageal conditions was associated with frequent stent migration and long-term improvement in only one third of patients. Further investigation is required before recommending FCSEMS placement to treat benign diseases of the esophagus and to further characterize the subgroup that might benefit from these interventions.

Abstract
OBJECTIVES Partially covered self-expanding metal stents (SEMSs) are regularly used for malignant and occasionally for benign esophageal disorders. Safe removal of these stents can be challenging due to embedding of the uncovered stent ends. Our aim is to report the results of removal of embedded, partially covered SEMSs by induction of pressure necrosis using the stent-in-stent technique. METHODS Consecutive patients referred to three endoscopy units in 2007-2009, treated by the stent-in-stent technique, were reviewed. The partially covered SEMSs were inserted for malignant (n=3) or benign (n=16) conditions and were left in situ for a median of 42 days (14-189). When SEMSs were found to be embedded, a fully covered self-expanding plastic stent (SEPS) or fully covered SEMS was placed inside the partially uncovered SEMS. Subsequent removal of both stents was planned after a period of 10-14 days. RESULTS In total, 23 stent-in-stent procedures were performed in 19 patients (10 males). Placement of a fully covered stent (SEPS: n=9 and SEMS: n=14) was technically successful in all patients. In 21 of 23 (91%) procedures, both stents were successfully removed in one procedure after a median of 12 days (5-18). In two patients, a repeat stent-in-stent procedure was needed for persistent embedding of the partially uncovered SEMSs. One (5%) procedure was complicated by severe bleeding, which could be treated endoscopically. In seven (36%) patients, the initial disorder had resolved after stent removal and no further endoscopic interventions were needed. Two (10%) patients were treated with chemoradiation or surgery for esophageal cancer after stent removal. In 10 (53%) patients, a repeat endoscopic intervention was required during follow-up because of progressive dysphagia or a persisting leak or fistula. CONCLUSIONS The stent-in-stent technique is safe and effective for the removal of partially covered SEMSs that are embedded in the esophageal wall.

Abstract
BACKGROUND The application of stents in benign colorectal strictures is considered controversial. The aim of the present study was to assess effectiveness and complications associated with colorectal stent placement in benign colorectal disease. PATIENTS AND METHODS Fourteen patients with benign colorectal strictures who had undergone previous surgery (colorectal anastomotic stenosis, 13; neosphincter scar stenosis, one) were treated with covered self-expanding metal stent or plastic stent. Placement of the stent was performed with combined endoscopy and contrast enhanced fluoroscopy. RESULTS Self-expanding stents were successful implanted in all 14 patients without acute procedure-related complications. All patients experienced immediate decompression after stent placement with expansion and patency of the stent. Relief of bowel obstruction for at least 12 months was achieved in seven of 14 patients (50%). Anastomotic fistula healed in four of six patients (67%). Despite the initial success of stenting, re-operations had to be performed in two of seven patients because of late recurrence of the stricture after a mean follow-up of 37 months. CONCLUSIONS Temporary insertion of self-expanding stents is a safe procedure that may be effective in selected cases of benign colorectal stricture. However, repeat surgery will be necessary in a considerable number of patients due to primary or secondary failure of stenting.

Abstract
BACKGROUND Management of anastomotic biliary strictures after liver transplantation deserves optimization. OBJECTIVE To evaluate placement and removal of partially covered self-expandable metal stents (PCSEMSs) in this setting. DESIGN Prospective, multicenter, uncontrolled study. SETTING Three French academic hospitals with liver transplantation units and tertiary referral endoscopy centers. PATIENTS Twenty-two patients (18 men, 4 women, aged 49.7 ± 12 years) with anastomotic biliary stricture. Seventeen (77.3%) presented stricture recurrence after plastic stenting. INTERVENTIONS PCSEMSs were placed across the stricture for 2 months and then removed. Patients were followed by clinical examination and liver function tests 1, 3, 6, 9, and 12 months after PCSEMS removal. MAIN OUTCOME MEASUREMENT The ability to remove PCSEMS. RESULTS PCSEMS placement was successful in all patients, after sphincterotomy in 21 patients. Stent-related complications included minor pancreatitis (3 patients), transient pain (1 patient), and cholangitis (1 patient). Stent removal was achieved in all patients but 2 whose stents had migrated distally. Partial stent dislocation was noted in 5 patients (upward in 4, downward in 1). Complications associated with stent removal were minor, including self-contained hemorrhage (1 patient) and fever (1 patient). The stricture persisted at the end of treatment in 3 patients (13.6%), all of whom had stent migration or dislocation. Recurrence of anastomotic stricture after initial success occurred in 9 of 19 patients (47.4%) within 3.5 ± 2.1 months. Sustained stricture resolution was observed in 10 of 19 patients (52.6%), 45.6% from an intent-to-treat perspective. LIMITATIONS Uncontrolled study with limited follow-up. CONCLUSIONS Temporary placement and removal of PCSEMSs in anastomotic biliary strictures after liver transplantation is feasible, although sometimes demanding. Stent migration may impair final outcome.

Abstract
BACKGROUND Benign esophageal strictures refractory to standard dilation therapy present a challenging problem. Temporary plastic and metal stents have been proposed with inconclusive results. OBJECTIVE To evaluate the efficacy and safety of a new biodegradable stent for the treatment of refractory benign esophageal strictures (RBESs). DESIGN AND SETTING Prospective study from 2 European endoscopy centers. PATIENTS AND INTERVENTION Twenty-one patients (11 men/10 women, mean age 60.2 ± 17.6 years) with RBESs defined according to the Kochman criteria treated by placement of a biodegradable stent (Ella stent). MAIN OUTCOME MEASUREMENTS Clinical and endoscopic follow-up was scheduled at 1, 2, 3, and 6 months and later only in case of dysphagia recurrence. Pre- and poststenting dysphagia status was graded according to a 5-point scale. Minor and major complication rates were prospectively assessed. RESULTS Stent insertion was technically successful in all of the patients. At 4 and 7 weeks, stent migration occurred in 2 patients (9.5%). At 3-month endoscopy, the stent appeared to be almost completely fragmented in all remaining patients. The median pre- and poststenting dysphagia scores were 3 (range 3-4) and 1 (range 0-2), respectively (P < .01), with a median follow-up of 53 weeks (range 25-88 weeks). In detail, 9 of 20 patients (45%) were dysphagia free at the end of the follow-up. No major complications occurred. Severe poststenting pain requiring analgesics developed in 3 patients, and minor bleeding was observed in 1 patient. LIMITATIONS Limited follow-up; nonrandomized study. CONCLUSIONS In this preliminary study, the biodegradable stent showed a favorable risk/benefit ratio, achieving complete relief of dysphagia in nearly 50% of RBES patients without the occurrence of major complications. The use of this stent may be a valuable alternative to repeat endoscopic dilation. Larger studies with longer follow-up are needed.

Abstract
BACKGROUND Fully covered self-expandable metal stents (FCSEMSs) have been proposed for the treatment of benign esophageal diseases. OBJECTIVE To review our experience with FCSEMSs in patients with benign esophageal diseases. DESIGN Retrospective case review of patients who underwent FCSEMS placement for benign esophageal diseases, including (1) benign strictures from GERD--caustic and idiopathic causes, (2) radiation-induced strictures, (3) anastomotic strictures, (4) esophageal fistulae/leaks, and (5) esophageal perforations. SETTING Tertiary-care medical center. PATIENTS This study involved 37 male and 19 female patients (average age 60 years, range 25-94 years) who underwent FCSEMS placement. INTERVENTION FCSEMS placement. MAIN OUTCOME MEASUREMENTS Technical success with stent placement and removal, stent migration, long-term and short-term complications, and treatment success according to clinical symptoms, follow-up endoscopy, or imaging. RESULTS Stent placement was successful in 100 of 107 (93%) procedures, with a total of 104 stents placed. Migration was noted in 37 of 104 (35.6%) stents and was seen more frequently with proximal stents and stents placed for anastomotic strictures. Initial treatment success was seen in 56% of patients with any stricture and in 38% of patients with a fistula/leak or perforation, although data to document long-term resolution were lacking. LIMITATIONS This was a retrospective review with patients selected from a tertiary-care medical center. Two endoscopists performed the majority of procedures. CONCLUSION Temporary placement of FCSEMSs for benign esophageal diseases has moderate clinical efficacy and is limited by stent migration. Removability was easily demonstrated. Newer developments in stent design may improve clinical outcomes for these patients.

Abstract
BACKGROUND Treatment of refractory or recurrent benign oesophageal strictures is demanding and surgery may be the only available option. The role of self-expanding plastic stents (SEPS) in the treatment of these strictures is still controversial because of the conflicting results of various studies. AIM To analyse with regard to SEPS: technical and clinical success, factors associated with outcome, and safety. METHODS Pooled-data analysis of a systematic review of the literature. Clinical success was defined as no need for further endoscopic or surgical treatment after SEPS removal. RESULTS Data of 10 studies with 130 treated patients were included. SEPS insertion was technically successful in 128 of 130 patients (98%, 95% CI = 96-100%). Clinical success was achieved in 68 patients (52%, 95% CI = 44-61%) and this was found to be lower in those with a cervical localization of the stricture (33% vs. 54%; P < 0.05). Early (<4 weeks) migration of the stent was reported in 19 (24%, 95% CI = 14-32%) cases, while post-insertion endoscopic re-intervention was required in 25 (21%, 95% CI = 14-28%). Major clinical complications occurred in 12 patients (9%, 95% CI = 4-14%), resulting in death of one (0.8%) patient. CONCLUSIONS Our pooled-data analysis showed a favourable risk/benefit ratio when SEPS are applied in patients with recurrent or refractory benign oesophageal strictures. This supports the use of SEPS before referring patients to surgery, and they are a valuable alternative to repeat endoscopic dilation.

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.

Abstract
BACKGROUND Benign gastroesophageal anastomotic strictures are common and often refractory to treatment. Various endoscopic dilation techniques have been reported, but none of these methods has been proven to be superior. OBJECTIVE Comparison of the efficacy and safety of dilation of previously untreated anastomotic strictures by using electrocautery incision (EI) and Savary bougienage (SB). DESIGN Randomized, prospective study. SETTING Multicenter study. PATIENTS Sixty-two patients with an anastomotic stricture after esophagogastrostomy and dysphagia Atkinson grades II to IV were included. INTERVENTIONS Patients were treated with EI or SB. MAIN OUTCOME MEASUREMENTS Objective and subjective results were compared with baseline and 1, 3, and 6 months after the first treatment. Complications of both treatments were noted. Primary endpoints after 6 months were the mean number of dilation sessions and success rate (percentage of patients with < or =5 dilations in 6 months). Study participation ended after 6 months or if dysphagia grades II to IV recurred despite 5 treatment sessions. RESULTS No complications occurred with both treatments. There was no significant difference between the EI and SB groups in the mean number of dilations (2.9; 95% CI, 2.7-4.1 vs 3.3; 95% CI, 2.3-3.6l; P = .46) or the success rate (80.6% vs 67.7%, P = .26 and 96.2% vs 80.8%, P = .19). LIMITATIONS In a small study with negative primary endpoints, secondary endpoints and subgroup analyses are hypothesis generating only. CONCLUSIONS This prospective trial demonstrated that EI of gastroesophageal anastomotic strictures is a safe therapy and equivalent to SB as a primary therapy. EI can be used as an alternative or additional therapy to SB. (Registered with Current Controlled Trials, Ltd, registration number ISRCTN81239664.).

Abstract
After liver transplantation, the most common biliary complication is the anastomotic stricture, which is followed by biliary leakage. Studies have focused on the endoscopic treatment of biliary complications in transplanted patients with duct-to-duct reconstruction, showing a success rate of 70% to 80% after orthotopic liver transplantation and of 60% after living-related liver transplantation. Once the endoscopic approach fails, surgical treatment with a Roux-en-Y choledochojejunostomy is the sole alternative treatment. The aim of this prospective observational study was to analyze the efficacy and safety of fully covered self-expandable metallic stents for the treatment of posttransplant biliary stenosis and leaks in patients in whom conventional endoscopic retrograde cholangiopancreatography (ERCP) failed. From January 2008 to January 2009, 16 patients met the criteria of endoscopic treatment failure, and instead of surgery, a fully covered stent was placed. All patients had at least 6 months of follow-up (mean follow-up of 10 months). After removal, 14 patients showed immediate resolution of both the biliary stenosis and leak. After a mean of 10 months of follow-up, only 1 patient showed biliary stenosis recurrence. No major complications occurred in any of the patients, except for stent migration in 6 patients, although these presented with no clinical consequences. In conclusion, in patients not responding to standard endoscopic treatment, the placement of fully covered metal stents is a valid alternative to surgery. A cost analysis should be performed in order to evaluate whether to treat transplanted patients suffering from biliary complications with covered self-expandable metallic stent placement as first-line therapy.

Abstract
BACKGROUND Benign anastomotic esophageal stricture after surgical resection is not uncommon and requires repeated dilation sessions to maintain patency because of the significant recurrence rate with bougie or balloon dilation. OBJECTIVE Our study was designed to evaluate whether a modified method of incisional therapy is effective and maintains a good patency in a benign anastomotic esophageal stricture. DESIGN A prospective outcome study. SETTING Tertiary-care academic medical centers. PATIENTS A total of 24 patients with benign anastomotic esophageal strictures after esophagojejunostomy. INTERVENTIONS Under direct vision through a transparent hood, radial incisions parallel to the longitude of the esophagus were performed by pulling up the Iso-Tome or insulated-tip-knife. MAIN OUTCOME MEASUREMENTS Efficacy, safety, and long-term patency after procedures were evaluated. RESULTS During 24 months of follow-up observations, 21 of 24 patients (87.5%) who received only 1 dilation session resumed eating solid meals and had no dysphagia. Only 3 patients (12.5%) developed restricture at a mean of 1.6 months. Of the patients with a recurrence, 2 experienced no recurrence after one additional dilation session, and another patient was refractory and underwent 5 dilation sessions. The occurrence of restricture after incisional therapy was statistically more prevalent in long-segment stricture (>1 cm) (2/3 [66.7%]) than short-segment stricture (<1 cm) (1/21 [4.8%]) (P = .032). There were no significant procedure-related complications. LIMITATION Our study included a small number of patients. Therefore, further prospective randomized controlled trials are needed. CONCLUSIONS A modified method of incisional therapy as a primary treatment is safe and feasible, and appears to maintain a longer duration of patency in benign anastomotic esophageal stricture.

Abstract
The indications for interventional treatment (endoscopic or surgical) of chronic pancreatitis can be classified in several major groups of lesions or symptoms: pain, consequences of fibrosis on neighboring organs (biliary, duodenal or even colic stenosis, thrombosis of the splenic vein with segmental portal hypertension), consequences of duct rupture above the obstacle (persistent symptomatic pseudocyst, refractory pancreatic ascites), and suspected cancer. Finally, surgery is indicated for patients for whom endoscopic procedures are impossible (papillae inaccessible) or too close together. Recently, two new criteria have been suggested: the number of procedures necessary for achieving the objective set, and the duration of hospitalization.

Endoscopic therapy for esophageal perforation or anastomotic leak with a self-expandable metallic stent. Surg Endosc 2009; 23:2258-62.

Abstract
BACKGROUND Leaks of the esophagus are associated with a high mortality rate and need to be treated as soon as possible. Therapeutic options are surgical repair or resection or conservative management with cessation of oral intake and antibiotic therapy. We evaluated an alternative approach that uses self-expandable metallic stents (SEMS). METHODS Between 2002 and 2007, 31 consecutive patients with iatrogenic esophageal perforation (n = 9), intrathoracic anastomotic leak after esophagectomy (n = 16), spontaneous tumor perforation (n = 5), and esophageal ischemia (n = 1) were treated at our institution. All were treated with endoscopic placement of a covered SEMS. Stent removal was performed 4 to 6 weeks after implantation. To exclude continuous esophageal leak after SEMS placement, radiologic examination was performed after stent implantation and removal. RESULTS SEMS placement was successful in all patients and a postinterventional esophagogram demonstrated full coverage of the leak in 29 patients (92%). In two patients, complete sealing could not be achieved and they were referred to surgical repair. Stent migration was seen in only one patient (3%). After removal, a second stent with larger diameter was placed and no further complication occurred. Two patients died: one due to myocardial infarction and one due to progressive ischemia of the esophagus and small bowl as a consequence of vascular occlusion. Stent removal was performed within 6 weeks, and all patients had radiologic and endoscopic evidence of esophageal healing. CONCLUSIONS Implantation of covered SEMS in patients with esophageal leak or perforation is a safe and feasible alternative to operative treatment and can lower the interventional morbidity rate.

Abstract
The purpose of this study was to evaluate the effectiveness of temporary metallic stenting in 55 patients with treatment-resistant benign esophageal strictures and to identify factors associated with clinical outcomes. Under fluoroscopic guidance, covered retrievable stents were placed in 55 patients with benign esophageal strictures and were removed with retrieval hook 1 week to 6 months after placement. Stent placement was successful in all patients, and the mean dysphagia score was reduced from 2.8 to 1.3 (p<0.001). The most common complications were tissue hyperproliferation (31%), severe pain (24%), and stent migration (25%). During follow-up (mean: 38 months), recurrence of the stricture necessitating balloon dilation was seen in 38 (69%) of 55 patients. Maintained patency rates after temporary stenting at 1, 3, and 6 months and 1, 2, and 4 years were 58%, 43%, 38%, 33%, 26%, and 21%, respectively. In multivariate analysis, length (p=0.003) of the stricture was the only significant factor associated with maintained patency after temporary stenting. In conclusion, temporary metallic stenting for refractory benign esophageal strictures may be effective during the period of stent placement, but is disadvantaged by the high recurrence rates after stent removal, particularly in patients with a long length of stricture (>7 cm).

Abstract
BACKGROUND Anastomotic leaks after colorectal operation continue to be a significant cause of morbidity. A covered endoluminal stent could seal a leak and eliminate the need for diversion. The aim of this study was to test the efficacy of a temporary covered stent to prevent leak related complications. METHODS Sixteen adult pigs (80-120 lbs) underwent open transection of the rectosigmoid followed by anastomosis with a circular stapler. Eight animals (study group) underwent endoscopic placement of a 21-mm covered polyester stent. Eight control group animals were left without stents. In all animals, a 2-cm leak was created along the anterior portion of the anastomosis. The animals were killed after 2 weeks and evaluated for abdominal infection, fistulae, and adhesions. The anastomosis was excised and the following parameters were assessed by a pathologist blinded to treatment: mucosal interruption (mm), inflammatory response, collagen type I and III, granulation, and fibrosis (grade 0-4). RESULTS Stents were spontaneously expelled between postoperative days 6 and 9. At necropsy, none of the animals in the study group had leak related complications, whereas in the control group, 5 (63%) developed intraabdominal infection (4 abscesses, 1 fistula) at the anastomosis (P = .002). Dense adhesions to the anastomosis were found in 7 (88%) control animals. On histology, anastomotic sites in the study group had significantly less mucosal interruption and granulation. Two pigs in the study group died on postoperative day 7, one due to evisceration and one from bladder necrosis. The mortality result is not different from controls (P = .47), both events seem to be unrelated to stent placement. CONCLUSION Temporary placement of a covered polyester stent across a colorectal anastomosis prevents leak-related complications and supports the healing of anastomotic leaks.

Abstract
BACKGROUND Intra-thoracic esophageal leakage after esophageal resection or esophageal perforation is a life-threatening event. The objective of this non-randomized observational study was to evaluate the effects of endoluminal stent treatment in patients with esophageal anastomotic leakages or perforations in a single tertiary care center. METHODS Thirty-two consecutive patients with an intrathoracic esophageal leak, caused by esophagectomy (n = 19), transhiatal gastrectomy (n = 3), laparoscopic fundoplication (n = 2), and iatrogenic or spontaneous perforation (n = 8), undergoing endoscopic stent treatment were evaluated. Hospital stay, mortality and morbidity, sealing rate, extraction rates, complications, and long-term effects were measured. RESULTS Median time interval between diagnosis and stent treatment was 3 and 5 days, respectively. Eighteen patients had futile surgical closure of the defect before stenting, while in 14 patients, stent placement was the primary treatment for leakage. Stent placement was technically correct in all patients. Functional sealing was achieved in 78%. Mortality was 15.6%. Stent extraction rate was 70%. Overall method-related complications occurred in nine patients (28%). CONCLUSIONS Implantation of self-expanding stents after esophageal resection or perforation is a feasible and safe procedure with an acceptable morbidity even if used as last-choice treatment.

Abstract
The aim of our retrospective study was to determine the incidence of benign anastomotic strictures (BAS) in patients after esophageal resection and to examine the influence of the extent of BAS on the results of bougienage therapy. From January 2001 to July 2006, 79 patients at risk of BAS development were included in the study. BAS was diagnosed with a median delay of 8 weeks (4-26) postoperative in 23 patients (29%). A median of 4 bougienage sessions (2-20) was needed for success (success rate 100%). The mean follow-up time was 22 months [range 3-47]. There were no late recurrences of BAS. Five patients had an anastomosis diameter <5.5 mm and 14 patients >5.5 mm. There was no difference in median number of bougienage procedures in these subgroups (4.5 [2-9] vs. 4 [2-20]). Patients who presented with BAS earlier than 6 weeks postoperative had more procedures (median 8 [2-20] vs. 4 [2-9]) than those presenting later. Patients in whom first bougienage was possible to only 16 mm diameter needed more procedures than patients in whom first dilation was possible to more than 16 mm (median 5.5 [3-20] vs. 3 [2-9]). In conclusion, both early BAS development and the diameter of bougienage at first endoscopy, but not the extent of stricture, seem to be predictive factors for longer bougienage therapy. In order to influence the BAS formation early, we now routinely examine every patient after esophageal resection endoscopically in the 6th postoperative week.

Abstract
BACKGROUND Benign biliary strictures (BBS) are usually managed with plastic stents, whereas placement of uncovered metallic stents has been associated with failure related to mucosal hyperplasia. OBJECTIVE We analyzed the efficacy and safety of temporary placement of a covered self-expanding metal stent (CSEMS) in BBS. DESIGN Patients with BBS received temporary placement of CSEMSs until adequate drainage was achieved; confirmed by resolution of symptoms, normalization of liver function tests, and imaging. SETTING Tertiary-care center with long-standing experience with CSEMSs. PATIENTS Seventy-nine patients with BBS secondary to chronic pancreatitis (32), calculi (24), liver transplant (16), postoperative biliary repair (3), autoimmune pancreatitis (3), and primary sclerosing cholangitis (1). INTERVENTION ERCP with temporary CSEMS placement. Removal of CSEMSs was performed with a snare or a rat-tooth forceps. MAIN OUTCOME MEASUREMENTS End points were efficacy, morbidity, and clinical response. RESULTS CSEMSs were removed from 65 patients. Resolution of the BBS was confirmed in 59 of 65 patients (90%) after a median follow-up of 12 months after removal (range 3-26 months). If patients who were lost to follow-up, developed cancer, or expired were considered failures, then an intent-to-treat global success rate of 59 of 79 (75%) was obtained. Complications associated with placement included 3 post-ERCP pancreatitis (4%), 1 postsphincterotomy bleed (1%), and 2 pain that required CSEMS removal (2%). In 11 patients (14%), the CSEMS migrated. In 1 patient, CSEMS removal was complicated by a bile leak that was successfully managed with plastic stents. LIMITATION Pilot study from a single center. CONCLUSIONS Temporary CSEMS placement in patients with BBS offers a potential alternative to surgery.

Abstract
BACKGROUND A benign gastroesophageal anastomotic stricture occurs in up to 42% of patients after transhiatal esophagectomy for esophageal cancer. Management of anastomotic strictures may require extended periods of serial endoscopic dilation, with significant risk, cost, and inconvenience for the patient. OBJECTIVE To determine if placement of removable self-expandable polyester silicon-covered (Polyflex) stents (SEPSs) prolonged the interval between endoscopic interventions in the management of persistent anastomotic stricture. DESIGN Retrospective cohort study. SETTING National Cancer Institute designated comprehensive cancer center. PATIENTS Eight patients after a transhiatal esophagectomy referred for management of benign persistent anastomotic strictures. INTERVENTIONS Serial balloon and bougie dilations and SEPS placement. MAIN OUTCOME MEASUREMENT The interval between endoscopic interventions and the number of endoscopic interventions before and after SEPS placement. RESULTS Over a 365-day period, 13 SEPS were placed in 8 patients with benign persistent anastomotic strictures after a transhiatal esophagectomy. A SEPS placement delayed the interval between endoscopic interventions from a mean of 7 days before stent insertion to 62 days after insertion (P < .008). The median number of preinsertion interventions was 4 and was reduced to 1 after insertion (P < .005). LIMITATION The small number of patients. CONCLUSIONS A SEPS placement did not result in stricture resolution or stabilization after SEPS removal. The SEPS migration rate was much higher in our patients with postesophagectomy anastomotic strictures than previously reported for other types of strictures. However, a SEPS placement did significantly delay the interval between endoscopic interventions in patients with persistent gastroesophageal anastomotic strictures after transhiatal esophagectomy. SEPS placement should be considered as an alternative to continued serial dilation in patients with persistent anastomotic strictures after transhiatal esophagectomy.

Abstract
Until recently, esophageal stents have not been a realistic option for the management of benign disease owing to difficulty removing the stents and associated high complication rates. However, progress in esophageal stent design has led to the development of retrievable esophageal stents. Clinical experience has shown promise for the management of benign esophageal diseases with retrievable stents, including refractory strictures, esophageal leaks, fistula and perforations. They have been shown to be safe and effective, though stent migration remains a concern. This article reviews the current designs, indications, efficacy and complications of retrievable esophageal stents.

Abstract
BACKGROUND Recently, self-expanding plastic stents (SEPSs) have been proposed for the treatment of benign esophageal disease. OBJECTIVES Our purpose was to review our experience with SEPSs in patients with benign esophageal conditions. DESIGN This was a retrospective case review of patients who underwent SEPS placement for benign esophageal disease, including (1) benign stricture, including reflux disease, ischemia, and idiopathic, (2) radiation-induced strictures, (3) anastomotic strictures, and (4) esophageal leak/fistulae. PATIENTS Nineteen male and 11 female patients (average age 52.1 years, range 11-87 years) underwent SEPS placement. INTERVENTIONS SEPS placement. MAIN OUTCOME MEASUREMENTS Initial complications, stent migration, long-term complications, and treatment success according to clinical symptoms, follow-up endoscopy, or imaging. RESULTS Eighty-three of 84 SEPS placements were successful. The most common complications were chest pain, dysphagia, nausea, and vomiting. No deaths were reported from stent placement. Stent migration was more frequent in proximal (30/44 stents, 68.1%) and distal (19/27 stents, 70.4%) compared with mid esophageal (3/10 stents, 30%). Migration was more frequent in stents placed for benign strictures (18/22 stents, 81.8%), anastomotic strictures (18/24 stents, 75%), and fistulae/leak (13/22 stents, 59.1%) compared with radiation-induced strictures (4/14 stents, 28.6%). Only 5 of 83 interventions (6%) resulted in long-term improvement after stent removal. LIMITATIONS This was a retrospective review, and patients were selected from a tertiary medical center. CONCLUSION Use of SEPSs for benign esophageal conditions resulted in frequent stent migration and few cases of long-term improvement. Further investigation is warranted to identify optimal patient populations and to guide future recommendations for the use of SEPSs.

Abstract
The application of stents in the GI tract has expanded tremendously. Stent placement is the most frequently used treatment modality for palliating dysphagia from esophageal or gastric cardia cancer. Newly designed esophageal stents, including the Polyflex stent and the Niti-S double stent, have been introduced to reduce recurrent dysphagia owing to migration or nontumoral or tumor overgrowth. Stents are also the treatment of choice for esophagorespiratory fistulas, for proximal malignant lesions near the upper esophageal sphincter, for recurrent carcinoma after esophagectomy or gastrectomy and for sealing traumatic or iatrogenic nonmalignant ruptures, such as Boerhaave's syndrome and leakages following surgery. Stents in the latter patient group should be removed within 4-8 weeks after placement to prevent the formation of granulation tissue or hyperplasia at the stent ends. For gastric outlet obstruction, many case series have been published. Only two, small, randomized controlled trials have compared stent placement with gastrojejunostomy to date, and a large, randomized trial is currently being conducted in The Netherlands. Obstructive jaundice caused by a malignancy in the common bile duct can be treated effectively with plastic or metal stent placement. However, a prognostic score needs to be developed that guides a treatment decision towards using either of these stents. Finally, colonic stents are applied successfully for acute malignant obstruction as a 'bridge to surgery' in patients with tumors that are deemed to be resectable, or as a palliative treatment for patients with locally advanced or metastatic disease.

Abstract
BACKGROUND The management of patients with refractory hypopharyngeal strictures after surgery in combination with radiation therapy is disappointing, and nutrition through feeding tubes is often required. OBJECTIVE To evaluate the efficacy and safety of a modified self-expanding Niti-S metal stent in the treatment of hypopharyngeal strictures after combined therapy for laryngeal cancer. DESIGN Case series. SETTING A general hospital and a university hospital. PATIENTS Seven consecutive patients were included. One of them did not have laryngectomy. INTERVENTIONS All patients received a modified Niti-S stent. MAIN OUTCOME MEASUREMENTS Improvement of dysphagia, avoiding periodic bougienage, and enteral nutrition through feeding tubes. RESULTS After placement of the first stent, dysphagia improved in all patients. Six of 7 patients developed stent migration and/or granulomatous tissue ingrowth or overgrowth. Additional stents were placed in all patients after a median of 3 months after the previous stent placement. One patient developed an esophagorespiratory fistula caused by a Polyflex stent. Two patients died of causes unrelated to the stent. The remaining 5 patients remained alive and asymptomatic after a median follow-up of 10 months. LIMITATIONS Periodic stent exchange. Stent placement did not resolve the stricture definitively. We had a limited number of patients and have no long-term outcome data yet. CONCLUSIONS The use of this modified Niti-S stent avoids both enteral nutrition through feeding tubes and the need for periodic bougienage in patients with difficult-to-treat benign hypopharyngeal strictures.

Abstract
A covered expandable esophageal metallic stent was placed to treat a corrosive esophageal stricture that was refractory to repeated balloon dilations. The stent was removed 8 years after placement due to severe dysphagia. The stented esophageal area has since maintained long-term patency for 2 years. These results suggest the feasibility of removal of a metallic stent after long-term stent placement.

Abstract
The present report describes the intentional retrieval of six Viabil stent-grafts from the biliary system. The six stent-grafts were successfully removed from five patients with a mean time from placement to retrieval of 38 days. Successful retrieval was independent of underlying disease etiology and included strictures associated with benign disease, malignant disease, disease of unknown etiology, and stent-graft misplacement. There were no complications resulting from stent-graft retrieval. Intentional removal of Viabil stent-grafts is technically feasible. Further study is necessary to establish its potential role in the management of biliary disease.

Abstract
OBJECTIVE The use of stents for benign colorectal obstruction is considered controversial because of a lack of data and perceived high failure and complication rates. The aim of this study was to evaluate the indications and outcomes following stent placement for benign colorectal disease in a UK district general hospital and to review the published literature. PATIENTS AND METHODS Between 1997 and 2004, 11 of 90 attempted stent insertions were performed for benign colorectal disease (diverticular disease, 4; anastomotic strictures, 4; idiopathic rectal stricture, 1; rectal endometriosis, 1; caecal volvulus, 1). Complications and outcomes were analysed from a prospective database. RESULTS Stent insertion was successful in nine patients. Early complications occurred in two patients (both with diverticular disease): one patient failed to decompress and needed a colostomy and laparotomy was performed in a second patient who developed peritonitis after five days although no stent perforation of the bowel was identified. Two patients were successfully decompressed and underwent subsequent elective surgery with full bowel preparation. Stent placement resulted in symptomatic improvement in three out of four patients with anastomotic strictures (allowing closure of defunctioning stomas) and in the one patient with an idiopathic rectal stricture. Stent migration occurred in two of these patients without recurrence of symptoms. Stent fracture occurred in one patient, who remained symptomatic. CONCLUSIONS Self-expanding metallic stents are an effective treatment for benign colorectal obstructions, especially anastomotic strictures with long-term patency. Stents should be avoided in acute diverticular disease because of a higher incidence of complications.

Abstract
BACKGROUND Anastomotic esophageal stenoses after esophageal resection are common and sometimes are refractory to Savary bougie dilation. The efficacy of electrocautery needle-knife treatment in these patients is described. METHODS Twenty patients with a refractory anastomotic stricture of the esophagus were treated with electrocautery and were followed for 12 months. All patients had recurrence of dysphagia despite repeated bougienage. OBSERVATIONS All 12 patients with a stricture shorter than 1 cm remained without dysphagia after a single treatment. In all 8 patients with a long-segment stenosis of 1.5 to 5 cm, dysphagia recurred, and a mean of 3 treatments were necessary. The interval between electrocautery treatments was significantly longer compared with bougienage. There were no complications. The body weight of all patients increased. CONCLUSIONS Electrocautery seems to be a good single-treatment modality for refractory short-segment anastomotic strictures, whereas longer-segment stenoses appear to require repeated treatment sessions before similar results are obtained.

Abstract
Esophageal perforations are surgical emergencies with high mortality rates. A variety of treatment strategies have been advocated. No single strategy has however, been fully applicable to deal with most situations. The aim of this study was to investigate if treatment with covered expandable metallic stents could offer a feasible option for the management of a leaking esophagus regardless of cause. Twenty-two consecutive patients with perforation or leakage from the intrathoracic esophagus were endoscopically treated with placement of a covered expandable metallic stent. Nine patients had esophageal cancer and 13 had benign underlying disease of whom two had a leakage from a surgical anastomosis. The leakage could be sealed in all but one patient. This patient died after an open esophageal diversion procedure. Twelve patients had an uneventful recovery, whereas three patients needed percutaneous drainage of abscesses and one drainage of the pleural cavity through a small thoracotomy. One patient required a conventional thoracotomy to drain the mediastinum. In total five (23%) patients died from the perforation within 30 days. Two of the deaths were unrelated and three (14%) related to the perforation. In patients with benign disease stents were removed or replaced after 3 weeks. In total 17 stents were successfully removed. Leakage from a damage esophagus can be effectively covered by expandable metallic stents seemingly regardless of the underlying cause and is likely to offer a good chance of survival even in severely ill patients.

Abstract
BACKGROUND Esophageal non-malignant perforations are severe life-threatening conditions. The current treatment is either surgical or conservative. METHODS We report a case series of 3 consecutive patients (1 female, 2 male; 34-68 years) treated with expandable covered stents for non-malignant iatrogenic esophageal perforations. OBSERVATIONS In our series, 3 out of 3 patients sealed their perforations and resumed normal oral intake. Complications observed were 2 stent migrations, which occurred at 6 and 11 months after stent insertion, a stenosis due to acid reflux treated by another stent insertion above the first one. On the basis of the data available, it appears that esophageal stents was successful in 82% of the cases. The mortality and complication rates were of 7% and 32% respectively. The main complications observed were peptic stenosis above the stent and fistulas. CONCLUSION These results are promising but need to be confirmed in large-scale prospective studies. Mediastinal drainage remains mandatory when sepsis is present.

Abstract
Mediastinal lymphoma is a rare cause of tracheoesophageal fistula (TEF). While most reports described in the literature have been related to prior or concurrent chemoradiation therapy, TEF has rarely been reported as the initial presentation of lymphoma. We report on a young woman found to have Hodgkin's disease complicated by TEF that required emergent placement of an esophageal stent. The lymphoma was successfully treated and, due to stent-related symptoms, removal was desired but not technically possible. We discuss options that may prevent this predicament in the future.
