Small bowel intubation is a useful method in the non-operative decompression of small bowel obstruction andenteral hyperalimentation in malnurished patients. We have tried small bowel intubation with Ventrol tube guidedby small bowel enteroclysis guide wire(Bilbao-Dotter wire) in 12 patients Ten cases were successfully intubated. In 11 cases of bowel obstruction, 9 cases were intubated and 8 cases were efffectively drained. One malnurishedpatient was improved in nutritional state after enteral hyperalimantation through the intubated tube. We believethis method is an easy and time-saving method in the small bowel decompression.
