Description

A review of anaemic patients referred for imaging following negative upper and lower GI endoscopy showed that barium follow-through was not helpful. Other tests may be more useful.

Outcome of imaging investigations in patients with iron deficiency anaemia Dr Peng Hui LEE ( Radiology) Dr Sanjeev KALRA ( Medicine) Mid Essex Hospitals Chelmsford, Essex, UK

Introduction IDA: GI blood loss most common cause in men and post menopausal women No obvious cause: gastro & colonoscopy If endoscopy -ve: imaging (?)

IDA: GI blood loss most common cause in men and post menopausal women

No obvious cause: gastro & colonoscopy

If endoscopy -ve: imaging (?)

Method Radiology records of endoscopy patients (9 Aug – 17 Jun 2008) If patients had BaFT, US, CT or Ba enema: endoscopy records checked for indications (Non-university public hospital)

Radiology records of endoscopy patients (9 Aug – 17 Jun 2008)

If patients had BaFT, US, CT or Ba enema: endoscopy records checked for indications

(Non-university public hospital)

Results 39 patients: Normal gastroscopy and normal/incomplete colonoscopy 25 Ba FT: all normal 10 Ba En (1 carcinoma) 11 CT (2 positive) 3 US (normal)

39 patients: Normal gastroscopy and normal/incomplete colonoscopy

25 Ba FT: all normal

10 Ba En (1 carcinoma)

11 CT (2 positive)

3 US (normal)

Results Positive CT: Liver mets + colonic mass incomplete colonoscopy, no Ba enema Lung mets on CXR CT :primary not found

Positive CT:

Liver mets + colonic mass incomplete colonoscopy, no Ba enema

Lung mets on CXR CT :primary not found

Discussion Low yield from BaFT Rockey (NEJM 1993 ): 100 IDA: 38 neg gastro & colonoscopy: 26 enteroclysis, 3 BaFT: all -ve. Till  ( Gut   1992 ): 89 IDA & +ve FOB: 18 BaFT all -ve

Discussion Good results from enteroclysis in some studies Moch, Herlinger, Kochman, Levine, Rubesin, Laufer (AJR 1994): 128 pt GI bleeding: 32 +ve: 19 TP (17 SB tumours, 3 AVM) 5 FP 8 stopped bleeding Malik ( Dig Dis Sci 2005): 67 pt GI bleeding: 27 (21%) +ve

Conclusion IDA ; -ve gastro & colonoscopy: Ba FT unhelpful VCE generally recommended if further investigation needed CT enterography/enteroclysis may prove to be useful (Some people seem to be very good at enteroclysis)

IDA ; -ve gastro & colonoscopy:
