Abstract:
Objective To investigate the feasibility and clinical value of double-balloon endoscopy in subjects of failed conventional colonoseopy and gastro-intestinal tract modified surgery.Methods Doubleballoon endoscopy was performed in thirty-two subjects of failed conventional colonoscopy,three and nine patients of previous subtotal gastrectomy with BillrothⅡand gastro-intestinal modified surgery for various clinical manifestations.Suceessful intubation rates of terminal ileum or cecum in colonoscopic failure patients,afferent and efferent loop intubation in patients of BillrothⅡand alimentary tract modified surgery,were recorded and diagnostic yields in these patients were also observed.Results The endoscopy was successfully intubated into terminal ileum or cecum in 29 subjects,the intubated rate was 90.6%,the endoscopic diagnosis was obtained in 7 subjects,and endoscopic treatment was performed in 3 subjects.The endoscopy was successfully inserted in terminus of afferent loop and 150-180 cm of efferent below the anastomosis in all 3 patients of Billroth type Ⅱ gastrectomy,and the diagnosis was all clarified.And endoscopic retrograde cholangiopancreatography was performed in one patient.Five of nine patients with previous alimentary tract modified surgery had lesions detected after endoscopic procedure,and double-balloon endoscopy could have a thorough visualization on operated area and suspected region as needed.Abdominal pain and melaena were observed in 8 and 3 subjects respectively.Transient urine amylase elevation was found in one patient.The symptoms were alleviated and amylase was returned to normal after treatment.Conclusions Double-balloon endoscopy was a safe and feasible remediai endoscopic procedure with high diagnostic yields and endotherapeutic interventional capability,in patients of failed conventional colonoscopy and previous BillrothⅡgastrectomy and alimentary modified surgery.
