Summary Background Placement of self‐expanding metal stents (SEMS) or plastic stents (SEPS) has emerged as a minimally invasive treatment option for benign oesophageal ruptures and leaks; however, it is not clear which stent type should be preferred. Aim To assess clinical effectiveness and safety of treating benign oesophageal ruptures and anastomotic leaks with temporary placement of a stent with special emphasis on different stent designs. Methods A pooled analysis was performed after searching PubMed and EMBASE databases for studies regarding placement of fully covered and partially covered SEMS (FSEMS and PSEMS) and SEPS for this indication. Data were pooled and evaluated for clinical outcome, complications and survival. Results Twenty‐five studies, including 267 patients with complete follow‐up on outcome, were identified. Clinical success was achieved in 85% of patients and was not different between stent types (SEPS 84%, FSEMS 85% and PSEMS 86%, P = 0.97). Time of stent placement was longest for SEPS (8 weeks) followed by FSEMS and PSEMS (both 6 weeks). In total, 65 (34%) patients had a stent‐related complication. Stent migration occurred more often with SEPS [n = 47 (31%)] and FSEMS [n = 7 (26%)] than with PSEMS [n = 2 (12%), P ≤ 0.001], whereas there was no significant difference in tissue in‐ and overgrowth between PSEMS [12% vs. 7% (FSEMS) and 3% (SEPS), P = 0.68]. Conclusions Although there is a lack of randomised controlled trials, it seems that covered stent placement for a period of 6–8 weeks is safe and effective for benign oesophageal ruptures and anastomotic leaks to heal. As efficacy between different stent types is not significantly different, stent choice should depend on expected risk of stent migration (self‐expanding plastic stents and fully covered self‐expanding metal stents) and, to a minor degree, on expected risk of tissue in‐ or overgrowth (partially covered self‐expanding metal stents).

“…Esophageal stent implant is an important method to treat esophageal stenosis with many kinds of stents showing anti reflux function. [14][15][16] The stent without anti reflux function is likely to damage barrier function of esophagus and cardia. When a stent is placed under the UES or LES, the function of esophageal body is completely shielded, leading to the induction of LPR.…”

Background/Aims To establish an animal model of laryngopharyngeal reflux (LPR) and study the effect of LPR on the laryngopharyngeal mucosal ultrastructure. Methods Ten Bama minipigs were randomly divided into control group and stent group. Every pig underwent endoscope, and baseline pH was monitored for 4 hours at laryngopharynx and distal esophagus, then specimens from laryngopharyngeal mucosa were biopsied. For the control group, these procedures were repeated on the 14th day. In the stent group, a custom-designed esophageal stent suit was implanted into esophagus, laryngopharyngeal and distal esophageal pH monitoring lasted for 2 hours, then stent suit was removed 3 days later. At last, the same procedures were done as the control group on the 14th day. Specimens were observed under transmission electron microscope to measure the intercellular space and desmosome number. Results In the control group, there was no laryngopharyngeal reflux on the first day and 14th day. Before the stent was implanted, there was also no laryngopharyngeal reflux in the stent group. In both 2 hours and 14 days after stent implantation, the num -ber of reflux, reflux time, and percentage time of pH < 4.0 were significantly increased ( P < 0.05) in the stent group. There was no difference in intercellular space and desmosomes in the control group between baseline and 14th day. In the stent group, intercellular space of laryngopharyngeal mucosa was significantly increased (0.37 μm vs 0.96 μm, P = 0.008), and the number of desmosomes was significantly decreased (20.25 vs 9.5, P = 0.003). Conclusions A Bama minipig model of LPR was established by implanting a custom-designed stent suit. LPR might destroy the laryngophar yngeal mucosal barrier.

“…In patients with EPF, who do not undergo treatment develop an unremitting respiratory tract flawing, consequently leading to pulmonary sepsis and death, as a result there is difficulty in making early diagnosis and timely treatment. Esophageal stent placement has been used to manage esophageal fistulas [7,8] . Due to their lesser complications, self-expanding metallic stents are used in majority of patients [9] .…”

Development of malignant esophago-pleural fistulas is relatively rare but life-threatening complication. We present a 50 year-old female patient with 6 months history of distal esophageal carcinoma. Patient presented with right sided chest pain, dysphagia, dyspnoea, cough and fever. Right side pyopneumothorax was diagnosed and intercostal drainage (ICD) tube was inserted. Presence of food material in the drainage bag led to the diagnosis of oesophageal-pleural fistula. Self expandable stent was placed, however 1 month later stent migration was observed and patient expired due to worsening pyopneumothorax and sepsis.
