文摘

Gastric cancer is highly prevalent in Kashmir, as are lower gastrointestinal (LGI) malignancies. Colonic cancer, gastric cancer, and coeliac disease are the most important gastrointestinal (GI) causes of iron deficiency anaemia (IDA) worldwide. Approximately 9% of patients with IDA present with a suspicious lesion in the GI tract upon examination. However, the absence of GI symptoms and a possible lesion accounting for blood loss in IDA have not been studied in this zone with a high prevalence of GI malignancy. We aimed to examine IDA patients without GI symptoms to determine the most plausible cause of their blood loss.

Patients and methods

A total of 100 patients with IDA and 250 control subjects without IDA and referred for gastrointestinal endoscopy were enrolled in a cross-sectional, comparative study. Patients presenting with a significant lesion proportionate to their anaemia in the upper GI tract were not examined further, if no further strong indications were present.

Results

Twenty-nine patients (29%) were found to have malignancy: 13 with gastric cancer and 16 with colonic malignancies. Other apparent causes of GI blood loss included peptic ulcer disease in 10 (10%) patients, haemorrhoids in 22 (25%), polyps in eight (three in the upper GI tract and five in the LGI tract), gastric erosions in eight (8%), and angiodysplasia, diverticulitis, and trichuriasis in two (2%) each.

Conclusion

In light of the high incidence of GI malignancies in this patient group, a low threshold for GI screening as well as mass screening for IDA is needed.
