Abstract
BACKGROUND Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures. METHODS Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed. Primary outcomes included technical success, early clinical success, and adverse events (AEs). Other outcomes included rates of stent migration and re-intervention after LAMS removal. RESULTS One hundred and nine patients who underwent 128 LAMS placements (67.9% female, mean age of 54.3 ± 14.2 years) were included, and 70.6% of the patients had failed prior endoscopic treatments. The majority of strictures (83.5%) were anastomotic, and the most common stricture site was the gastrojejunal anastomosis (65.9%). Technical success was achieved in 100% of procedures, while early clinical success was achieved in 98.4%. The overall stent-related AE rate was 25%. The migration rate was 27.3% (35/128). Of these, five stents were successfully repositioned endoscopically. The median stent dwell time was 119 days [interquartile range (IQR) 68-189 days], and the median follow-up duration was 668.5 days [IQR: 285.5-1441.5 days]. The re-intervention rate after LAMS removal was 58.3%. CONCLUSIONS LAMS is an effective therapeutic option for benign GI strictures, offering high technical and early clinical success. However, the re-intervention rate after LAMS removal was high. In select cases, using LAMS placement as destination therapy with close surveillance is a reasonable option.

Abstract
Self-expandable plastic stents are currently recommended for refractory benign esophageal strictures but they show disappointing results in terms of migration and long-term efficacy. We report here our experience in the management of benign esophageal strictures with partially covered (PCSEMS) and fully covered self-expandable metal stents (FCSEMS). We performed a retrospective analysis of self-expandable metal stent (SEMS) placements for benign esophageal strictures from 1998 to 2011 in Rouen University Hospital. Twenty-two patients (15 men, 7 women) attempted 40 esophageal SEMS placements (17 PCSEMS, 23 FCSEMS) during this period. All technical complications were migrations. Migration was noted after 3/17 PCSEMS (17.6%) and 4/23 FCSEMS placement (17.4%, P = ns). Clinical complications occurred after 6/17 PCSEMS and 2/23 FCSEMS placements (35.3% vs. 8.7%, P = 0.053). PCSEMS caused two major complications (fistulae) whereas FCSEMS did not cause any major complication (11.7% vs. 0%). Mean dysphagia score was significantly lower after SEMS placement (1.68 vs. 3.08, P < 0.001) with similar results for PCSEMS and FCSEMS. Stent placement resulted in long-term clinical success for 23.5% of PCSEMS and 34.7% of FCSEMS (P = 0.0505). FCSEMS provide satisfying clinical success rate with an acceptable complication rate and they could constitute a relevant therapeutic option in the management of benign esophageal strictures.

Abstract
OBJECTIVE To date, there is no standardized treatment for esophageal perforations and leakages caused by underlying benign diseases, and it is still debated whether a conservative, endoscopic treatment or a surgical approach is preferable. However, some cases series have successfully demonstrated the feasibility of a temporary placement of self-expanding stents. DESIGN All patients with benign leakages of the esophagus or gastroesophageal junction or fistulas at gastroesophageal anastomosis were collected during the past 12 years and analyzed retrospectively. The patients treated with endoscopic stenting were analyzed for sustained success, complications, time to stenting, lesion size, number of stents used, need for percutaneous drainage. RESULTS Eighty-five of eight-eight patients were included in this analysis. Three patients were conservatively managed only. The success rate of stent treatment with an average of 1.3 stents was 79%. Success was highest (94%, n = 30 of 32, no complications or mortality) in iatrogenic lesions that were immediately diagnosed and treated. Spontaneous lesions, including lesions due to Boerhaave's syndrome, were healed in 73% and anastomotic leakages were closed in 71%. Fistula had a lower success rate of 43%. Use of multiple stents sequentially placed was necessary in 23% of the cases. Percutaneous drainage was necessary in 25% of all cases. CONCLUSION Temporary stent placement for benign leakages of the esophagus is safe and seems to improve treatment success. Adjacent fluid collections should be drained percutaneously.

Abstract
The usefulness of a covered self-expandable metallic stent for benign esophageal stricture and perforation was well established. In case of benign disease, early stent removal was recommended within 6-8 weeks after placement. A case with severe esophageal stricture caused by incomplete stent removal 7 years after stent placement for spontaneous esophageal rupture was reported. Residual stent fragments could be removed by step-by-step multimodal endoscopic treatment, producing satisfactory luminal diameter of the esophagus. In particular, stent trimming with argon plasma coagulation was safe and effective strategy. The endoscopic stent removal is minimally invasive and should be attempted before surgical intervention; however, it is most important to ensure early stent removal before tissue ingrowth or overgrowth can develop.

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 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 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
OBJECTIVES The standard approach to benign esophageal perforations consists of conservative treatment or surgery. In this study, we investigated the efficacy of short-term stent placement for nonmalignant esophageal perforations. METHODS This is a prospective single-center study of patients with benign esophageal perforations in whom a removable self-expandable stent was placed. Data were collected from a prospective database, endoscopy records, and operation reports. To obtain follow-up data, we contacted the patients, their relatives, or their general practitioner. RESULTS A total of 33 patients underwent stent insertion owing to an iatrogenic perforation (n=19), Boerhaave's syndrome (n=10), or other causes (n=4); this resulted in an immediate and complete sealing of the lesion in 32 patients (97%). Stents migrated in 11 patients (33%). Four patients required an esophageal resection for failed stent therapy (n=3) and failed stent removal (n=1). The 90-day mortality rate was 15%. A total of 33 endoscopic stent extractions were attempted. Overall, 23 stents were extracted within 6 weeks (group I) and 10 stents between 6 and 84 weeks (group II). Extractions were uncomplicated in all patients in group I (100%) vs. in 5 patients in group II (50%) (P=0.001). Six extraction-related complications occurred in group II, including two self-limiting bleedings, three stent fractures, and one impacted stent. CONCLUSIONS In patients with a benign esophageal perforation, temporary stent therapy is effective and provides a good alternative to surgery. Complications due to stent removal can be prevented by removal of the prosthesis within 6 weeks after insertion, without compromising the efficacy of treatment.
