FACTORS ASSOCIATED WITH TECHNICAL SUCCESS IN COLONIC STENT PLACEMENT

Aims:

To evaluate factors associated with the successful placement of colonic stents.

Tab. 1:

Multivariate analysis of factors associated with technical success in endoscopic stent placement

	Sig	OR (CI 95%)
Peritoneal carcinomatosis	0,025	0,309 (0,111 – 0,861)
Expert endoscopist	0,003	3,935 (1,602 – 9,668)

Methods:

We performed an observational and retrospective study of patients attended in a single center between 2007 and 2014, with colonic stents placed for any reason. Technical success was defined as the correct placement of the stent in the radiological image. Three doctors had more experience in endoscopic stents and skills in ERCP, and were referred to “experts”.

Results:

There were included 217 patients, with technical success in 189 (87,1%). There were no differences attending to the length of the stent, level of the neoplasia, or emergency setting. The groups of expert endoscopists achieved a technical success in 110 (93,2%) cases, and the other group in 79 (79,8%), with an OR 3,4 (1,4 – 8,3). In the multivariate analysis, the presence of peritoneal carcinomatosis was associated with less technical success and the experience of the endoscopist with higher.

Conclusions:

In our study, the technical success of the placement of colonic stents was associated with the experience of the endoscopist and the absence of peritoneal carcinomatosis.
