“…This stent is composed of a polyester mesh with a silicone covering and has the theoretical advantages compared with self-expanding metallic stents of being removable and decreased tissue ingrowth [9]. Two small studies from 2004 reported dysphagia improvement in over 70% of patients after Polyflex TM stent placement and removal [10,11].…”

“…SEMS are collapsed and inserted via a delivery system, which facilitates placement, minimizes the need for dilation, and reduces the incidence of trauma and perforation during insertion [9]. Uncovered SEMS have been associated with tumor in-growth and mucosal hyperplasia [7,8,10,11].…”

“…Some studies [24][25][26] concluded that stent placement has been shown to be an excellent treatment in patients with mediastinal abscess in GEAL, while others [27] revealed that certain problems might be associated with stent placement and removal: insufficient closure of the leaks, stent migration and development of strictures after stent removal, severe complications such as bleeding and food blockage, and hard removal because of the growth of granulation tissue. Han et al [7] treated the patients of mediastinal abscess with stent placement and nasaloesophagus drainage.…”

Objective The aim of this study was to retrospectively evaluate the technical success rates and clinical effectiveness of fluoroscopically guided nose tube drainage of mediastinal abscesses and a nasojejunum feeding tube in post-operative gastro-oesophageal anastomotic leakage (GEAL). Methods From January 2006 to June 2011, 18 cases of post-operative GEAL with mediastinal abscesses after oesophagectomy with intrathoracic oesophagogastric anastomotic procedures for oesophageal and cardiac carcinoma were treated by insertion of a nose drainage tube and nasojejunum feeding tube under fluoroscopic guidance. We evaluated the feasibility of two-tube insertion to facilitate leakage site closure and complete resolution of the abscess, and the patients’ nutritional benefit was also evaluated by checking the serum albumin level between pre- and post-enteral feeding via the feeding tube. Results The two tubes were placed successfully under fluoroscopic guidance in 18 patients (100%). The procedure time for two-tube insertion ranged from 20 to 40 min (mean 30 min). 17 patients (94%) achieved leakage site closure after two-tube insertion and had a good tolerance of two tubes in the nasal cavity. The serum albumin level was significant, increased from pre-enteral feeding (2.49±0.42 g dl−1) to the post-enteral feeding (3.58±0.47 g dl−1) via the feeding tube (p<0.001). The duration of follow-up ranged from 1 to 49 months (mean 19 months). Conclusion The insertion of nose tube drainage and a nasojejunum feeding tube under fluoroscopic guidance is safe, and it provides effective relief from mediastinal abscesses in GEAL after oesophagectomy. Moreover, our findings indicate that two-tube insertion may be used as a selective procedure to treat mediastinal abscesses in post-operative GEAL. Advances in knowledge Directive drainage of mediastinal abscesses in post-operative GEAL may be an effective treatment.
