Jl. Cronstedt et al., SELF-EXPANDING NITINOL STENT FOR MALIGNANT OBSTRUCTIVE DYSPHAGIA - INITIAL EXPERIENCE, Annals of saudi medicine, 15(6), 1995, pp. 594-597
Between July and December 1994, a total of 31 patients with inoperable
or unresectable malignant obstruction of the esophagus or esophagogas
tric junction were palliated with self-expanding nitinol stents. They
were 33 to 86 years old, 55% being 70 years or older. Twenty patients
were male. Twenty patients (65%) had squamous cell carcinoma, 10 (32%)
had adenocarcinoma and one (3%) had undifferentiated carcinoma. Twent
y-five patients (81%) required prestenting dilatation with balloons, b
ougies or laser. Stent implantation was successful in 30 patients (97%
) but failed in one. Two patients had minor complications and one pati
ent with advanced disease died in the hospital one week after the proc
edure. All stented patients experienced significant short-term relief
of dysphagia. Twenty-two patients (73%) were seen at least once after
discharge in a follow-up visit. Twenty (66%) were still swallowing sat
isfactorily when last seen four to 32 weeks after stenting. We conclud
e that the new nitinol stent represents an important and valuable addi
tion to the treatment options available for palliation of malignant dy
spha dysphagia.
