In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: Benign esophageal strictures are frequently encountered pathologies occurring due to various reasons. Repeated dilatations may be needed, particularly in resistant strictures. This study aimed to evaluate patients who underwent repeated dilatations in our clinic due to resistant esophageal strictures.', 'Sixteen patients who underwent multiple dilatations in our clinic with the diagnosis of resistant benign esophageal stricture between 2007 and 2014 were studied for age, sex, etiology, symptoms, complications, number of dilatations, and intervals between dilatations. Under general anesthesia, all patients underwent dilatation with Savary-Gilliard bougie dilators with the help of rigid esophagoscopy.', 'In 10 of the patients, stenosis was cervical, and in others it was in the thoracic esophagus. The mean dilatation performance was 4.4 (range: 3-12). In 9 patients, dilatations were performed when the patients presented with the complaint of dysphagia. Following the initial dilatation performed for dysphagia, 7 patients underwent endoscopy and dilatation 3-5 times with 1-week intervals without waiting for the development of dysphagia symptoms. These patients developed no complications, and no stenting was needed. In 5 patients, restenosis developed despite multiple dilatations, and esophageal stent placement was performed.\Question: Is recurrent dilatation in resistant benign esophageal strictures : timing significant?

Output: Dilatations performed at frequent intervals without waiting for the symptoms of dysphagia can contribute to safer and more effective results in resistant benign esophageal strictures.


Input: Consider Input: Context: Surgery has been the gold standard in the treatment of adult pyloric stenosis (APS). The introduction of proton pump inhibitors (PPIs) in 1989 revolutionised the treatment of peptic ulcer disease and its complications.', 'We carried out a prospective study to evaluate the effectiveness of PPIs as an alternative to surgery for treatment of APS. Six consecutive patients admitted with a diagnosis of adult peptic pyloric stenosis between November 1999 and August 2002 were studied. The diagnosis was confirmed with endoscopy. All patients were commenced on a twice-daily dose of intravenous PPI. This was changed to oral treatment after 2 days. Main outcome measures evaluated were resolution of symptoms on PPIs and failure of medical therapy.', 'There were five females and one male. Median age at diagnosis was 72 years (range, 30-90 years). Median duration of symptoms was 2 weeks (range, 1-5 weeks). Of the patients, five had a history of peptic ulcer disease. Complete resolution was achieved in 5 patients (83%). Median duration for resolution of symptoms was 9 days (range, 5-14 days). All patients were changed to oral PPIs after 2 days. One patient did not respond to oral therapy and required surgical intervention (pyloroplasty). Median follow-up was 26 months (range, 6-48 months). There was no recurrence of symptoms. All patients were discharged on low-dose PPI.\Question: Is proton pump inhibition a feasible primary alternative to surgery and balloon dilatation in adult peptic pyloric stenosis ( APS ) : report of six consecutive cases?

Output: This study supports the view that proton pump inhibitors are a safe and feasible alternative to surgery in adult pyloric stenosis secondary to peptic ulcer disease.


Input: Consider Input: Context: We investigated the effects of neutrophil elastase inhibitor ONO-5046 Na on lung ischemia-reperfusion injury in a canine model of single lung transplantation.', '24 mongrel dogs, 12 donors and 12 recipients, were used for single lung transplantation. Lung grafts were preserved for 18 h by cold ischemia then transplanted into the left thoracic cavity of recipients. In 6 recipients (ONO group), a bolus of ONO-5046 Na (10 mg/kg) was introduced before reperfusion and followed by continuous infusion (10 mg/kg/h). The remaining 6 recipients (control group) did not receive ONO-5046 Na and thus served as controls. We evaluated lung function and respiratory parameters over 240 min.', 'The total cell number in bronchoalveolar lavage fluid increased significantly in the control group in comparison to that in the ONO group. Histologic scores after 4 h of reperfusion and myeloperoxidase activity were significantly lower in the ONO group than in the control group.\Question: Does neutrophil elastase inhibitor ameliorate reperfusion injury in a canine model of lung transplantation?


Output: Neutrophil elastase inhibitor ONO-5046 Na may be useful in ameliorating lung reperfusion injury after transplantation.
