Retrospective comparison of outcomes and associated complications between large bore radiologically inserted gastrostomy tube types

摘要

Purpose: Multiple approaches to radiologically inserted gastrostomy (RIG) exist. The goal of this study was to compare 30-day outcomes and associated complications between large bore balloon-retained (BR), loop-retained (LR), and pull-type (PT) RIG devices. Methods: Data on 1477 patients who underwent RIG between January 1, 2005 and December 31, 2016 were collected retrospectively using a dedicated interventional radiology database and electronic medical record. Statistical analysis was performed to compare complication rates between BR, LR, and PT devices. Results: Ninety-eight percent (1477/1507) of the procedures were successfully performed. A total of 752 BR, 323 LR, and 402 PT gastrostomy tubes were placed. The overall complication rate for BR catheters was 5.7% (25 major [3.3%] and 18 minor [2.4%]). The overall complication rate for PT catheters was 3.7% (8 major [2.0%] and 7 minor [1.7%]). The overall complication rate for LR catheters was 1.6% (4 major [1.4%] and 1 minor [0.8%]). Compared to BR catheters, LR catheters had significantly fewer total complications (P = 0.01) but not minor complications (P = 0.052). There were no significant differences in the number of complications between LR and PT catheters or between BR and PT catheters. Conclusions: Use of BR, LR, and PT devices for RIG is safe with a low incidence of complications. Compared to BR catheters, primary insertion of a LR gastrostomy was associated with significantly fewer overall complications within the first 30 days. Therefore, for initial tube placement, large bore LR catheters may be preferred over BR devices.
