Fully covered metal stents for the treatment of leaks after gastric and esophageal surgery
2015
Objective: The use of fully covered metal stents (FCMS) for
the treatment of benign conditions is increasing. The aim of our
study was to assess the efficacy of FCMS in the management of
post-operative leaks after gastric or esophageal surgery.
Material and methods: During a three year period (2011-
2013), patients who underwent a surgery related with esophageal
or gastric cancer and developed a postoperative anastomotic leak
treated with FCMS were prospectively included.
Results: Fourteen patients were included (11 men, 3 women),
with median age of 65 years. Placement of at least one stent was
achieved in 13 patients (93% of cases), with initial closure of the
leak in 12 of these 13 cases (92.3%). A final success (after removal
of the stent) could be demonstrated in 9 cases (69.2%, intention to
treat analysis); stent failed only in one case (7.7%) and there were
3 patients (23.1%) not evaluated because death before stent retrieval
(not related with the endoscopic procedure). One stent were used in
9 cases (69.2%), and two in 4 (30.8%). Migration was observed in
two cases (15.3%). There were no major complications related with
the use of stents. There were no complications related with retrieval.
Conclusions: The placement of FCMS to achieve the leak
closure after esophageal or gastric surgery is an effective and
probably safe alternative feasible with minor risks.
