Self-expanding metal stent in esophageal perforations and anastomotic leaks

Current endoscopic closure techniques for the management of gastrointestinal perforations

“…Evidence points towards high technical and clinical success ranging from 91% to 100 % and 82% to 91%, respectively. [54][55][56][57] A systematic review showed similar clinical success rates of 85%, however higher stent migration rates of 26% was reported for FCSEMS compared with a 12% rate for PCSEMS. 58 Hence, stent migration is a common problem and various techniques have been investigated to anchor the stent to the esophageal wall.…”

“…Self-expanding metal stents (SEMS) are emerging as a minimally invasive treatment alternative [5]. John and colleagues present a retrospective experience of SEMS in 26 patients for esophageal perforation (17 patients) and anastomotic leaks (9 patients) from Christian Medical College, Vellore, India over a 7-year period [6]. In this small series, stent placement (fully covered SEMS in 25) was successful in all the patients and of 22 patients available for follow-up, 20 had healed mucosal defects.…”

Terapia endoscópica a vácuo versus stents metálicos autoexpansíveis para o tratamento de defeitos transmurais do trato digestivo superior: revisão sistemática e metanálise

“…Vale salientar ainda que procedimentos adicionais, tais como drenagens percutâneas fazem parte da propedêutica no que diz respeito ao tratamento de defeito transmurais com próteses metálicas autoexpansíveis. Estes procedimentos adicionais também influenciam diretamente em desfechos como sucesso no fechamento do defeito transmural e mortalidade 72 .…”

“…Este evento pode determinar a necessidade de procedimentos menos invasivos, tais como endoscopia digestiva, mas também podem culminar em procedimentos cirúrgicos, aumentando ainda mais a morbidade e mortalidade relacionados aos defeitos transmurais. As taxas de migração das próteses metálicas são variáveis na literatura disponível, podendo variar de 11,5% até 20,5% 70,72 .…”
