Abstract

Fixation of an esophageal self-expandable metal stent (SEMS) with an over-the-scope-clip (OTSC) system for a benign stricture to prevent migration has been reported. However, the efficacy of SEMS fixation with an OTSC for malignant esophageal stricture remains unclear. The aim of this retrospective study was to evaluate the feasibility of SEMS fixation with an OTSC for a malignant esophageal stricture. Twelve patients who underwent esophageal SEMS placement and fixation with an OTSC for a malignant esophageal stricture were included in this retrospective study. The primary endpoint was technical success. The secondary endpoint was clinical success, which was defined as an improvement of at least 1 grade in the dysphagia score 1 week after SEMS placement or changes in the dysphagia score from before SEMS placement to 1 week after SEMS placement. The technical success rate was 100 %. The clinical success rate was 92.3 %. In 6 mild stricture cases in which a standard peroral endoscope could be used, no migration of the SEMS was observed. The median dysphagia score before and at 1 week after SEMS placement was 3 (range 2 - 4) and 0 (0 - 4), respectively, which indicated improvement at 1 week after SEMS placement compared with befor...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
