From the nuclear bomb to traffic rules, mankind has used technical ingenuity and legal strictures to constrain other powerful innovations.The spectre of eventually creating an autonomous non-human intelligence is so extraordinary that it risks overshadowing the debate.
Technical success and improvement in ductal strictures were achieved for almost all the cases, and stent-induced bile duct injuries were not observed.
Data on study design, number of patients, etiology and location of the stricture, route of stent placement, stent type, follow-up time, previous treatment, median stenting time, technical and clinical success rates, patency rate, complications, stricture recurrence and mortality were extracted.
Minimally invasive treatment of benign ureteral strictures is still challenging because of its technical complexity.
From a technical point of view, placement of an expandable stent in benign strictures does not differ from placement in cases of palliation of malignant dysphagia.
There are so many technical details involved that Kenyans living in North America simply let go of the strictures of tradition.
ITT, intention-to-treat; PP, per protocol; TS, technical success; FS, functional success; Group 1, patients with Bismuth type I malignant strictures; Group 2, patients with Bismuth type II malignant strictures; Group 3, patients with Bismuth type III and IV malignant strictures.
Cecal intubation was accomplished for all but three cases in the PEG-S group (two because of poor preparation, and one because of stricture) and two in the PEG-ELS group (one because of technical difficulty and one patient did not have a cecum but did have intubation of an ileocolonic anastomosis).
We sought to test the feasibility and technical ease of a newly designed nitinol based modified esophageal stent and its effects on preventing postcaustic stricture in mongrel dogs and to try to explain the result at the molecular level.
Technical success (TS) or successful stent insertion was defined as the passage of the stent across the stricture along with the flow of contrast medium and/or bile through the stent.
