Mushroom-cage gastrostomy tube placement in patients with amyotrophic lateral sclerosis: a 5-year experience in 104 patients in a single institution.

To review our experience of placement of a mushroom-cage gastrostomy tube (Entristar, Tyco Healthcare, Mansfield, MA), using radiological guidance, in patients with amyotrophic lateral sclerosis (ALS). All procedures were performed under local anaesthesia without sedation. Complications were recorded as peri-procedural, early (<24 h), late (>24 h), major or minor. Deaths were recorded as related to the underlying ALS or secondary to radiological-inserted gastrostomy (RIG) placement. Replacement RIG tube rate was recorded. Over a 5-year period RIG tubes were placed in 104 patients with ALS (male n = 52, female n = 52), with a median age of 62 years (range 34-86 years). All procedures were technically successful. Of the RIG procedures, 21/104 (20.2%) were performed with respiratory support. The 30-day mortality rate was 7/104 (6.7%); no patient died as a result of the procedure. There were 23/104 (22.1%) complications overall; 20/104 (19.2%) were minor and 3/104 (2.9%) major, requiring surgery (n = 2) and radiological-guided abscess drainage (n = 1). A median interval between replacement RIG procedures in 20/104 (19.2%) patients was 141.5 days (range 43-537 days). A mushroom-cage RIG tube may be safely and effectively inserted in a 'one-step' radiological procedure and may replace endoscopic-inserted gastrostomy tubes in the nutritional management of ALS.
