双气囊内镜在全结肠镜检查未抵达回盲部和胃肠道改道手术后患者中的应用

目的 研究双气囊内镜在常规全结肠镜检查未抵达回盲部、胃肠道改道手术后患者中应用的可行性与临床价值.方法 32例因各种原因未能完成全结肠镜检查者、3例毕Ⅱ式胃大部切除术者、9例有胃肠道改道手术史者因各种症状而行双气囊内镜检查.观察末端回肠,回盲部达到率、病变诊断率;胃大部切除术者输入襻,输出襻和胃肠道改道者的肠道检查成功率以及病变的诊断率;同时观察并记录与操作相关的并发症发生率.结果 32例全结肠镜未抵达回盲部患者中,双气囊内镜抵达回盲部或末端回肠者为29例(90.6%),7例患者获得明确诊断,完成内镜下治疗者3例;3例毕Ⅱ式手术者中,内镜均成功到达输入襻盲端以及吻合口下方输出襻150～180 cm,3例患者均明确诊断,其中1例完成内镜逆行胰胆管造影术(ERCP).9例改道手术患者中,5例行双气囊内镜检查后发现病灶;双气囊内镜能对所有患者手术区域肠道作完整全面的检查.在所有44例双气囊操作患者中,术后腹痛8例,少量黑便3例,尿淀粉酶一过性升高1例,对症处理后均消失.结论 双气囊内镜是常规全结肠镜检查未抵达回盲部和胃肠道改道手术后进行消化道内镜检查的理想、安全的方法,对病变有良好的诊断能力,并可进行必要的内镜下治疗.

Application of double-balloon endoscopy in subjects of failed conventional colonoscopy and surgically-modified gastrointestinal tract

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.
