Abstract:

Objective To explore the value of double balloon endoscopy (DBE) and small bowel computed tomography (CT) scan in the early diagnosis of small intestinal stromal tumors. Methods The data of patients with small intestinal stromal tumors confirmed by postoperative pathology were collected, and tumors with diameter less than 5 cm were defined as early stage small intestinal stromal tumors. The clinical and follow-up data of 61 patients with early stage small intestinal stromal tumors and complete medical records of DBE or small bowel CT scan were screened. The positive findings from gastroscopy, enteroscopy, abdominal B ultrasonography, angiography, capsule endoscopy, DBE, small bowel CT scan and combination examinations of DBE and small bowel CT scan, together with data of tumor recurrence and survival were retrospectively analysed. Results Before small bowel CT scan and DBE examinations, 61 patients underwent  the other examinations, and positive findings were obtained in 44 cases (72.13%). Fifty-six patients received single DBE examinations, with 52 (92.86%) positive findings, and 42 patients underwent single small bowel CT scan, with 37 (88.10%) positive findings. There was no significant difference in the detection rates between patients with single DBE examinations and those with single small bowel CT scan (P>0.05). Twenty-five patients received combination examinations of DBE and small bowel CT scan, and the detection rate was 100%. All patients were performed operations, with 35 months of median time of follow-up. There were 59 cases (96.7%) with disease-free survival and 2 cases with tumor-bearing survival (both of the 2 cases were treated with chemotherapy after tumor recurrence). Conclusion Both small bowel CT scan and DBE have high detection rates for small intestinal stromal tumors, and the combination of these two methods will be helpful for the early diagnosis and favourable prognosis.
