Prevention of aspiration pneumonia during long-term feeding by percutaneous endoscopic gastrostomy: might cisapride play any role? An open pilot study.

The risk of aspiration during tube feedings has been reduced but not abolished by percutaneous endoscopic gastrostomy (PEG). This open study was planned to evaluate whether cisapride may play some role in preventing aspiration in long-term enteral feeding via PEG. A group of 29 patients, unable to swallow because of head and neck cancer (14 cases) or neurological disorders (15 cases) entered the study; 7 neurological patients, fed via nasogastric tube before PEG placement, had suffered from aspiration pneumonia during nasogastric feeding. All patients underwent PEG, and 10 mg cisapride was routinely given via PEG before each administration of enteral feeding and 6 h after its initiation when the feeding was continued for 12 h or more. Only 1 minor complication was observed during the acute hospital setting (ileus, spontaneously resolving after 36 h). After hospital discharge, the patients were followed for a total of 4935 days of feeding (range 47-508 days, mean time per patient: 170 days) and assessed weekly for the development of complications. No episode of probable/possible aspiration pneumonia was observed during the follow-up. Two neurological patients with involuntary movements had rupture of the feeding tube, which was replaced without complications. These results support the hypothesis that cisapride might play some role in the prevention of aspiration in patients fed via PEG, and justify the planning of some controlled, double-blind trials to verify such a hypothesis.
