Evaluation of Patients with Jejunostomy Tubes: Imaging Findings¹

¹ From the Department of Radiology, Hospital of the University of Pennsylvania, 3400 Spruce St, Philadelphia, PA 19104. Received May 23, 2001; revision requested June 29; revision received September 6; accepted October 10. Address correspondence to M.S.L. (e-mail: levine@rad.upenn.edu).

PURPOSE: To determine the frequency and nature of abnormalities observed on radiographs after placement of jejunostomy (J) tubes for enteral nutrition.

MATERIALS AND 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.

CONCLUSION: 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).
