“…Shim et al 15 reported a technique consisting of a modified stent that was designed with a silk thread attached to the edge of the proximal end of the stent. Because this stent may not be routinely available, modifications of this technique using dental floss have also been reported 16 . With these techniques, after SEMS placement, the silk thread or dental floss is fixed to the patient’s earlobe or nose, and the external fixation is removed at least 2 weeks after the procedure.…”

Background and study aims 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. Patients and methods 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. Results 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 before SEMS placement ( P = 0.002). There were no adverse events associated with placement of SEMS and deployment of an OTSC. Conclusions SEMS fixation with an OTSC is feasible for prevention of migration due to a malignant esophageal stricture.

“…Retained materials manifest as welldefined soft tissue masses containing hypodense gas bubbles centrally ( Figure 15) (40). An intraluminal stent such as placed in esophageal strictures, especially self-expanding metallic esophagus stents, may migrate (41). When caught in a narrow site, metallic materials may cause obstruction and also cause dilatation in the proximal gastrointestinal tract ( Figure 16A-C).…”

Acute abdomen is one of the most common problems that radiologists face in daily practice. Imaging is used as the last stop before laparotomy, and computed tomography (CT) is now almost always the first step both in helping solve various difficult, urgent cases and in deciding on the management for the pain. In this study, we review a number of rare cases of abdominal pain in which the preliminary diagnosis could not be made clinically, but where CT images revealed the causes.

“…A fully covered metal stent was placed occluding the anastomotic leakage. To prevent stent migration, an external anchoring was performed with a piece of dental floss passed through the upper flange of the stent, as previous described by our group 2 . Since the stent is fully covered, a pediatric forceps was used to puncture the sheath, allowing the passage of the dental floss through the mesh.…”
