Abstract
One prime problem for patients with a jejunostomy is dehydration caused by the malabsorption of nutrients and large stomal losses of electrolytes and fluid．
This is a report of a rare case of a patient with a jejunostomy and length of residual jejunum of approximately 150cm,owing to recurrence by disseminated peritoneum after distal gastrectomy．The large output from a jejunostomy was treated by stricting the hypotonic fluid,using antidiarrheal agents-especially morphine for pain control of cancer,and the administration of isotonic fluid(Pocari Sweat TM)． The isotonic fluid was found to be effective as the output from the jejunostomy decreased from 4000ml to 2000ml and urinary volume increased．However,this was still not adequate because of a low concentration of electrolytes．For this reason,the application of electrolyte-rich ORS(oral rehydration solution)must be considered．
