Abstract
Pseudoachalasia accounts for up to 4% of patients who present with achalasia-like picture and most often relates to occult malignancy at the cardia or gastroesophageal junction. Thus, any delay in diagnosis might lead to more advanced disease and less chance for curative therapy, not to mention the risk of serious complications resulting from the treatment of supposed achalasia instead of the true underlying cause. The entity should be suspected in patients with advanced age of onset, a shorter duration of symptoms, profound weight loss and difficulty in passing the gastroesophageal junction on endoscopy. The diagnosis of pseudoachalasia can be challenging as upper endoscopy with biopsy might be false negative in 25% of cases and lesions cannot always be detected on computerized tomography scan. Endoscopic ultrasound and guided biopsy play an increasingly important role in the workup of this condition. Treatment of pseudoachalasia depends on the underlying cause. The aim of this review is to highlight the clinicopathological features that distinguish pseudoachalasia from achalasia and the most appropriate diagnostic workup as well as the subsequent management for this condition.

Abstract
Objectives: Household chemicals result in corrosive esophageal burns in the developing third world countries, and most of them cause esophageal strictures. There is no standard treatment for esophageal strictures. Here, we present our preliminary experience with intraluminal esophageal stents for stricture treatment. Methods: The files of the patients who had stenosis due to corrosive esophagitis in our clinic were evaluated retrospectively. Stricture lengths were between 30 and 130 mm. Stents were self-expandable, made of nitinol alloy that was covered with silicone, and they were cylindrical in shape with a conical tip. The lengths varied between 60 and 170 mm and the diameters were between 10-20 mm. The stent application was made under general anaesthesia. Results: There were seven patients (four girls and three boys). After stent application, all patients experienced constant or temporary pain, vomiting, and difficulty in swallowing. Bleeding occurred in one patient. Sudden death occurred in one patient, probably as a complication of chest infection. All stents had to be removed in mean 38 days because of embedding of the stent, development of granulation tissue and intolerance. Conclusion: More research is needed to determine the type, length and diameter of the stent, the timing and the duration of the application, the length and level of the stricture suitable for stent application and medications during treatment.

Abstract
Endoscopic stenting of the colorectum has emerged as a viable alternative to surgical interventions in a selected group of patients. The main indication for stenting is bowel obstruction. As such stenting can be used to palliate patients with metastatic disease or bridge patients to surgical intervention. The main advantages of stenting in the emergency setting include lower morbidity and mortality, lower incidence of stoma formation, shorter hospitalization, and better quality of life. For patients with unresectable disease and short life expectancy, stenting can be considered. However, for patients with longer life expectancy, the potential long-term complications of a metal stent such as erosion, migration, or obstruction have engendered debate whether such patients are better served by operative intervention. Stenting as a bridge to surgery is an alternative to surgery in patients who are high risk for emergency surgery but concerns remain regarding its impact on oncologic outcome in potentially curable patients.

Abstract
Endoscopic submucosal dissection (ESD) has been widely accepted as a curative treatment for gastric neoplasm. Pyloric stenosis is a chronic complication that can be caused by ESD. The aim of this study is to clarify the risk factors and management for pyloric stenosis. From January 2004 to January 2014, a total of 126 patients who underwent ESD adjacent to pylorus were reviewed retrospectively. Pyloric mucosal defect was defined as when any resection margin of ESD was involved in the pyloric ring. Pyloric stenosis was defined as when a conventional endoscope could not be passed to the duodenum. Among the 126 patients, pyloric stenosis was identified in 9. In a univariate analysis, pyloric stenosis was more common in older patients (P < 0.05) and in lesions with resections over 75% of the pyloric ring circumference (P < 0.001). In a multivariate analysis, the factor that was associated with pyloric stenosis was the extent of the pyloric ring dissection (P < 0.001). Four of the 9 patients with pyloric stenosis had mild dyspepsia, and the others had gastric outlet obstruction symptoms. The 5 symptomatic patients underwent endoscopic balloon dilation (EBD), and the frequency of EBD was 1 to 8 times. The asymptomatic patients were treated conservatively. The incidence of pyloric stenosis was higher in lesions with resections over 75% of the pyloric ring circumference. Although EBD was an effective treatment for pyloric stenosis, conservative management was also helpful in patients who had mild symptoms.

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
PURPOSE There is an increasing evidence base to support the use of self-expanding metallic gastrointestinal stents. In patients with colorectal cancer, they are used as a bridge to surgery and for palliation. The purposes of this study are to assess technical success, clinical outcome, complication rate and patency following colonic stent insertion in patients with colonic cancer at a local level and to compare our results with the current evidence base. METHODS A retrospective, two-centre study was conducted. Twenty-seven patients were included over a 5-year period. Six patients had undergone stent insertion as a bridge to surgery, and 21 had the procedure for palliation. RESULTS Initial technical success was achieved in 26 of 27 patients (96%). Of these 26 patients, clinical success was achieved in 24 patients (92%). Five patients (21%) suffered from stent re-occlusion, and one patient (4%) suffered from stent migration. There was one case (4%) of procedure-related perforation. Of the 19 palliative patients in whom clinical success was achieved, 17 (89%) were alive at 30 days, 13 (68%) at 90 (53%) days and 10 at 180 days. Average stent patency was 195 days. CONCLUSION WallFlex® self-expanding metallic gastrointestinal stents are a safe and effective means of alleviating obstructive symptoms in patients with colonic cancer requiring palliative treatment or as a bridge to surgery. Our data suggest that although a small percentage of patients are affected by stent re-occlusion, this does not contribute to premature mortality. They improve quality of life in palliative care patients as well as reducing premature morbidity and mortality caused by emergency surgery.

Abstract
OBJECTIVE The purpose of this article is to compare the efficacy of self-expanding metallic stents and pneumatic dilation for the long-term clinical treatment of achalasia. SUBJECTS AND METHODS Patients diagnosed with achalasia (n = 120) were allocated for treatment with pneumatic dilation (n = 30; group A) or a temporary self-expanding metallic stent with a diameter of 20 mm (n = 30; group B), 25 mm (n = 30; group C), or 30 mm (n = 30; group D). Data on clinical symptoms, complications, and long-term clinical outcomes were collected, and follow-up was performed at 6 months and at 1, 3-5, 5-8, 8-10, and more than 10 years after surgery. RESULTS Pneumatic dilation and stent placement were technically successful in all patients. The follow-up at more than 10 years revealed that the clinical remission rate in group D (83.3%) was higher than that in groups A (0%), B (0%), and C (28.6%), and the overall cumulative clinical failure rate in group D (13%) was lower than that in groups A (76.7%), B (53.3%), and C (26.7%). Patients in group D exhibited reduced dysphagia scores and lower esophageal sphincter pressures and had normal levels of barium height and width during the follow-up periods, whereas these markers increased with time in the other groups. The duration of primary patency in group D was also longer than that in groups A, B, and C. CONCLUSION A temporary self-expanding metallic stent with a diameter of 30 mm has superior clinical efficacy for the treatment of achalasia compared with pneumatic dilation or self-expanding metallic stents with diameters of 20 or 25 mm.

Abstract
AIM: To compare the efficacy of self-expanding metallic stents (SEMSs) for the long-term clinical treatment of achalasia.
METHODS: Ninety achalasic patients were treated with a temporary SEMS with a diameter of 20 mm (n = 30, group A), 25 mm (n = 30, group B) or 30 mm (n = 30, group C). Data on clinical symptoms, complications and treatment outcomes were collected, and follow-up was made at 6 mo and at 1, 3-5, 5-8, 8-10 and > 10 years, postoperatively.
RESULTS: Stent placement was successful in all patients. Although chest pain occurrence was high, stent migration was less in group C than in groups A and B. The clinical remission rate at 5-8, 8-10 and > 10 years in group C was higher than that in the other two groups. The treatment failure rate was lower in group C (13%) than in groups A (53%) and B (27%). SEMSs in group C resulted in reduced dysphagia scores and lowered esophageal sphincter pressures, as well as normal levels of barium height and width during all the follow-up time periods. Conversely, these parameters increased over time in groups A and B. The primary patency in group C was longer than in groups A and B.
CONCLUSION: A temporary SEMS with a diameter of 30 mm is associated with a superior long-term clinical efficacy in the treatment of achalasia compared with a SEMS with a diameter of 20 mm or 25 mm.

Abstract
The present study compares the efficacy of a self-expanding metallic stent (SEMS, diameter of 30 mm) and pneumatic dilation for the long-term clinical treatment of achalasia. A total of 155 patients diagnosed with achalasia were allocated for pneumatic dilation (n= 80, group A) or a temporary, 30-mm diameter SEMS (n= 75, group B). The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4-5 days after placement. Data on clinical symptoms, complications, and long-term clinical outcomes were collected, and follow-up observations were performed at 6 months and at 1, 3-5, 5-8, 8-10, and >10 years, postoperatively. Pneumatic dilation and stent placement were technically successful in all of the patients. There were no significant differences in technique success, 30-day mortality, or complications between the two groups. The clinical remission rate in group A was significantly lower than that in group B at 1, 1-3, 3-5, 5-8 and, >10 years (P < 0.05), while the cumulative clinical failure rate in group A (66%, 53/80) was higher than that in group B (92%, 6/75). The mean primary patency in group B was significantly longer than that in group A (4.2 vs 2.1 years, respectively; P < 0.001). A temporary, 30-mm diameter SEMS was associated with a better long-term clinical efficacy in the treatment of patients with achalasia as compared with treatment with pneumatic dilation.

Abstract
We present an 82-year-old woman with a 3-month history of progressive dysphagia and a normal initial upper gastrointestinal endoscopy. The diagnosis of pseudoachalasia was suspected by oesophageal manometric and barium swallow studies, and confirmed by biopsies revealing an intestinal type carcinoma of the stomach at a repeated endoscopy. In view of the history of heart disease, diabetes, and old age, this patient was treated by a partially covered Ultraflex self-expanding metal stent (Boston Scientific, Natick, MA, USA) placed into the oesophageal body with no direct complications and obtaining the relief from dysphagia. During the 11-month follow-up she was treated for an iron deficiency anaemia due to reflux oesophagitis with ulcerations in the oesophageal body and died from myocardial infarction. According to the localization of the cancer, the old age, and the presence of comorbidities, we should recommend the insertion of a partially covered self-expanding metal stent as a reasonable palliative treatment in selected subjects with pseudoachalasia.

Abstract
To prospectively evaluate the long-term clinical safety and efficacy of a newly designed self-expanding metallic stent (SEMS) in the treatment of patients with achalasia. Seventy-five patients with achalasia were treated with a temporary SEMS with a 30-mm diameter. The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4–5 days after stent placement. Follow-up data focused on dysphagia score, technique and clinical success, clinical remissions and failures, and complications and was performed at 6 months, 1 year, and within 3 to 5 years, 5 to 8 years, 8 to 10 years, and >10 years postoperatively. Stent placement was technically successful in all patients. Complications included stent migration (n = 4, 5.33%), chest pain (n = 28, 38.7%), reflux (n = 15, 20%), and bleeding (n = 9, 12%). No perforation or 30-day mortality occurred. Clinical success was achieved in all patients 1 month after stent removal. The overall remission rates at 6 months, 1, 1–3, 3–5, 5–8, 8–10, and >10 year follow-up periods were 100%, 96%, 93.9%, 90.9%, 100%, 100%, and 83.3%, respectively. Stent treatment failed in six patients, and the overall remission rate in our series was 92%. The median and mean primary patencies were 2.8 ± 0.28 years (95% CI: 2.25–3.35) and 4.28 ± 0.40 years (95% CI: 3.51–5.05), respectively. The use of temporary SEMSs with 30-mm diameter proved to be a safe and effective approach for managing achalasia with a long-term satisfactory clinical remission rate.

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 Esophageal strictures occur in 3% to 4% of patients with head and neck cancer who undergo radiation therapy. Some patients develop complete obstruction of the upper esophagus. Antegrade dilatation is often unsuccessful and many of these patients require surgery. OBJECTIVE To describe the outcomes and complications of an endoscopic antegrade-retrograde rendezvous procedure to restore esophageal patency. DESIGN Retrospective review of 8 cases treated with an endoscopic rendezvous procedure between August 2001 and April 2005. Medical records of consenting patients were abstracted for clinical history, procedural success, complications, and follow-up. SETTING A large tertiary referral center. PATIENTS Eight patients with head and neck or upper esophageal cancer and complete upper esophageal obstruction from radiation stricturing who underwent an attempted rendezvous procedure. MAIN OUTCOME MEASUREMENTS Clinical procedural success, reported adverse events. RESULTS Seven patients were men, and median age was 65 years. The median interval between radiation and the rendezvous procedure was 11 months. In 7 of 8 cases esophageal patency was restored and no major complications occurred. Two esophageal microperforations resolved without intervention. Most patients responded well to subsequent serial dilations and many discontinued gastrostomy tube use. LIMITATIONS Retrospective, selection bias. CONCLUSIONS An antegrade-retrograde rendezvous technique with subsequent dilation appears to be safe and effective for endoscopic management of complete upper esophageal obstruction induced by radiotherapy and can obviate the need for esophageal resection.

Abstract
AIM: To summarize our experience with the application of self-expanding metallic stent (SEMS) in the management of acute left-sided colorectal malignant obstruction.
METHODS: A retrospective chart review of all patients undergoing placement of SEMS between April 2000 and January 2004 was performed.
RESULTS: Insertion of SEMS was attempted in 26 patients under fluoroscopic guidance with occasional endoscopic assistance. The sites of lesions were located in splenic flexure of two patients, left colon of seven patients, sigmoid colon of eight patients and rectum of nine patients. The intended uses of SEMS were for palliation in 7 patients and as a bridge to elective surgery in 19 patients. In the latter group, placement of SEMS allowed for preoperative systemic and bowel preparation and the following one-stage anastomosis. Successful stent placement was achieved in 22 (85%) of the 26 patients. The clinical bowel obstruction resolved 24 hours after successful stent placement in 21 (95%) patients. Three SEMS-related minor complications occurred, two stents migrated and one caused anal pain.
CONCLUSION: SEMS represents an effective and safe tool in the management of acute malignant colorectal obstruction. As a bridge to surgery, SEMS can provide time for systematic support and bowel preparation and obviate the need for fecal diversion or on-table lavage. As a palliative measure, SEMS can eliminate the need for emergent colostomy.
