Evaluation of patients with jejunostomy tubes: imaging findings.
OBJECTIVE
To determine the frequency and nature of abnormalities observed on radiographs after placement of jejunostomy (J) tubes for enteral nutrition.


METHODS
Radiology database review revealed that 280 studies of the J tube or of the small bowel with water-soluble contrast material and/or barium sulfate were performed in patients during 10 years. Review of the radiologic reports revealed abnormalities related to the placement of tubes in 105 (38%) cases. Images were reviewed to determine abnormalities in these 105 cases. Radiologic, medical, and surgical records were also reviewed to determine the clinical course and any subsequent interventions.


RESULTS
One or more complications were detected in 40 (14%) of 280 cases: small-bowel obstruction in 17 (6%) cases, nonobstructive small-bowel narrowing in six (2%), extraluminal tracks or collections in seven (2%), extravasation of contrast material to the skin in 11 (4%), jejunal hematomas in five (2%), and intussusceptions in four (1%). Mechanical problems related to the tube were detected in 52 (19%) cases, including coiling, kinking, or knotting of the tube in 38 (14%), malpositioning in five (2%), retrograde flow in four (1%), occlusion in four (1%), and a hole in one (<1%). Focal thickening of small-bowel folds was detected in 24 (9%) cases.


CONCLUSIONS
Radiographs in 280 patients with J tubes revealed one or more complications that resulted from tube placement (40 [14%] cases), mechanical problems related to location or function of the tube (52 [19%] cases), and development of focally thickened small-bowel folds (24 [9%] cases).
