【摘要】:目的 探讨经口直视胆道内镜联合激光碎石治疗困难胆总管结石的效果。方法 选取2014年10月-2017年10月于兰州市第一人民医院行经内镜逆行胰胆管造影取石术的困难胆总管结石患者21例,所有患者行小内镜下十二指肠乳头括约肌切开术(切开缠头皱襞)后以结石最大直径或加2 mm为标准选取10~15 mm球囊行球囊扩张术;小乳头或憩室旁乳头则尽量切开乳头开口再扩张;憩室内乳头无法切开者直接球囊扩张。以10 mm取石球囊顺利进出为乳头开口扩大标准。超细内镜自乳头开口直接插入胆总管,直视下进行激光碎石,特制网篮取石并反复冲洗胆总管。结果 超细内镜均能进入胆总管并发现结石,成功率为100%。其中16例直接插入(66.7%),导丝辅助者5例(23.8%),外套管辅助2例(9.5%)。平均插入时间(4.9±2.9)min。碎石成功率为81.0%,碎石失败4例(19.0%)。无严重并发症,无手术相关死亡。1例(4.8%)术后发烧、右上腹痛并压痛,白细胞增高,降钙素原升高,以胆道感染给予抗生素治疗后好转。1例(4.8%)发生中度术后胰腺炎,经保守治疗好转。结论 经口直视胆道内镜对困难胆总管结石的诊治是一种安全有效的技术,联合激光碎石更具优势。
【Abstract】:Objective To investigate the clinical effect of direct peroral cholangioscopy combined with laser lithotripsy in the treatment of difficult bile duct stones. Methods A total of 21 patients with difficult bile duct stones who underwent cholecystolithotomy under endoscopic retrograde cholangiopancreatography in Lanzhou First People's Hospital from October 2014 to October 2017 were enrolled. All patients were treated with small endoscopic sphincterotomy, and balloons with a size of 10-15 mm were selected based on the maximum diameter (or maximum diameter+2 mm) of stones to perform balloon dilatation. The carunculae minor or the juxta-diverticulum papillae were cut open and then dilated, and those which could not be cut open were directly dilated with balloons. The criterion for papillary dilatation was that a 10 mm balloon could pass the papillary opening smoothly. The ultrafine endoscope was inserted into the common bile duct via the papillary opening, laser lithotripsy was conducted under the direct view, a specially designed basket was used to remove the stones, and the common bile duct was rinsed repeatedly. Results The ultrafine endoscope successfully entered the common bile duct and found the stones, with a success rate of 100%. Of all patients, 16 (66.7%) underwent direct insertion, 5 (23.8%) underwent insertion assisted by guide wire, and 2 (9.5%) underwent insertion assisted by outer casing. The mean insertion time was 4.9±2.9 minutes. The success rate of lithotripsy was 81.0%, and 4 patients (19%) experienced failed lithotripsy. There were no serious complications or surgery-related deaths during the treatment. One patient (4.8%) experienced fever, right upper abdominal pain and tenderness, and increases in leukocytes and procalcitonin after surgery and was improved after the treatment with antibiotics for biliary tract infection. One patient (4.8%) experienced moderate postoperative pancreatitis and was improved after conservative treatment. Conclusion Direct peroral cholangioscopy is a safe and effective technique for the diagnosis and treatment of difficult common bile duct stones. In particular, its combination with laser lithotripsy shows great advantages.
