A novel stent fixation method for anastomotic leaks after gastrectomy: anchoring of the distal flare to the jejunum by using through-the-scope endoclips

Introduction
An anastomotic leak is a life-threatening complication after gastrectomy. A fully covered, self-expandable, metal stent (FC-SEMS) can be used as an alternative to traditional surgical re-intervention. However, stent migration can be worrisome. Aim: To evaluate the feasibility and effectiveness of anchoring of the distal flare of the FC-SEMS to the jejunum by using through-the-scope (TTS) endoclips to prevent stent migration.

Material and methods
Patients, who received a FC-SEMS capable of being fixed to the jejunum by using TTS endoclips due to an anastomotic leak after gastrectomy, were reviewed retrospectively. Demographic and clinical characteristics, the properties of the deployed stents, and outcomes were evaluated.

Results
A total of 7 patients underwent FC-SEMS placement. The mean age was 59 ±13.8 years, and the mean body mass index was 29.8 ±8.4 kg/m2. All patients’ American Society of Anesthesiologists scores were between II and IV. The mean time between gastrectomy and stent insertion was 6.7 ±6.1 days. Technical success was achieved in all patients. Stent migration was not observed in any of the patients. All but one were removed between 4 and 6 weeks after placement. The mean stent removal time was 37 ±4.6 days. Complete resolution of the leak was achieved in 6 patients.

Conclusions
Anchoring of the distal flare of the FC-SEMS to the jejunum with TTS endoclips is feasible and may reduce the risk of migration. This inexpensive and safe technique may be proposed to patients with factors predictive of FC-SEMS migration.
