“…A plastic stent may also be used according to the preference of each facility with available equipment and techniques. (Grade 2, evidence level C) Statement: For the palliative treatment of distal bile duct obstruction, several randomized trials comparing plastic stent (PS) and uncovered SEMS showed that uncovered SEMS has significantly longer term patency than PS [100][101][102]. These trials also showed the lower complication rate of SEMS than PS.…”

Background The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract and ampullary carcinomas in 2008. Novel treatment modalities and handling of clinical issues have been proposed after the publication. New approaches for editing clinical guidelines, such as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, also have been introduced for better and clearer grading of recommendations. Methods Clinical questions (CQs) were proposed in seven topics. Recommendation, grade of recommendation and statement for each CQ were discussed and finalized by evidencebased approach. Recommendation was graded to grade 1 (strong) and 2 (weak) according to the concept of GRADE system. Results The 29 CQs covered seven topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, (6) radiation therapy, and (7) pathology. In 27 CQs, 19 recommendations were rated strong and 11 recommendations weak. Each CQ included the statement of how the recommendation was graded. Conclusions This guideline provides recommendation for important clinical aspects based on evidence. Future collaboration with cancer registry will be a key for assessment of the guidelines and establishment of new evidence.

“…The use of NiTi self-expandable stents is not limited to the vascular and neurosurgical fields: they are also used for the treatment of biliary obstruction [65][66][67], of tracheal stenosis [68,69], and of esophageal [70][71][72], rectosigmoidal [73], prostatic [74], and urethral [75,76] strictures. In these cases, the stent is often covered by a polymeric material to completely replace the conduit (stent-graft).…”

Shape memory alloys, and in particular NiTi alloys, are characterized by two unique behaviors, thermally or mechanically activated: the shape memory effect and pseudo-elastic effect. These behaviors, due to the peculiar crystallographic structure of the alloys, assure the recovery of the original shape even after large deformations and the maintenance of a constant applied force in correspondence of significant displacements. These properties, joined with good corrosion and bending resistance, biological and magnetic resonance compatibility, explain the large diffusion, in the last 20 years, of SMA in the production of biomedical devices, in particular for mini-invasive techniques. In this paper a detailed review of the main applications of NiTi alloys in dental, orthopedics, vascular, neurological, and surgical fields is presented. In particular for each device the main characteristics and the advantages of using SMA are discussed. Moreover, the paper underlines the opportunities and the room for new ideas able to enlarge the range of SMA applications. However, it is fundamental to remember that the complexity of the material and application requires a strict collaboration between clinicians, engineers, physicists and chemists for defining accurately the problem, finding the best solution in terms of device design and accordingly optimizing the NiTi alloy properties.

“…Recent trials with self-expanding metal stents have suggested both improved patency and a decreased incidence of recurrent jaundice and cholangitis when compared with polyethylene stents. 51 The choice between operative and nonoperative palliation may be a difficult one. Generally, patients who are good operative candidates, have a good performance status, and are expected to survive for a prolonged period (>6 months) should undergo surgical palliation.…”
