Abstract

BACKGROUND:

Self-expanding metal stents are used to palliate malignant strictures of the oesophagus. This study was designed to identify the characteristics of patients requiring restenting of malignant oesophageal strictures.

METHODS:

Fifty-three stents were inserted in 42 patients. Thirty-two patients did not require further stenting (once-stented group). Ten patients received second stents for recurrent oesophageal obstruction (restented group), with one patient requiring restenting a second time. Comparisons were drawn between the once-stented and restented groups with regard to survival, patient, tumour and procedural characteristics.

RESULTS:

There were no significant differences with regard to tumour grade, tumour type, involvement of the cardia, procedural difficulties or the need for postprocedural oesophageal dilatation between the two groups. Survival from initial stenting was significantly greater in the restented group (median 24 (range 4-43) weeks) than in the once-stented group (median 9.5 (range 1-84) weeks) (P < 0.05). The mean length of stents used in the once-stented group was significantly greater than that of the initial stents used in the restented group (12 versus 10 cm, P = 0.032).

CONCLUSION:

Inserting a covered stent through a previously inserted uncovered stent is an uncomplicated and well tolerated technique which maintains palliation from obstructing oesophageal carcinoma. The need for restenting cannot be predicted on the basis of tumour characteristics alone.
