Objective To investigate the effect of implanting uncovered self-expandable metal stent for treatment of distal malignant biliary obstruction through endoscope. Methods The effect of therapy about implanting uncovered self-expandable metal stents to 16 patients who had unsectable malignant tumors companing with obstructive jaundice through endoscope was reviewed. Results Fifteen of the studied patients were implanted uncovered self-expandable metal stents successfully (94%), for their internal drainage were patent. At the seventh and fourteenth day after implantation, liver function and B-ultrasound were rechecked. Compared to the data before operation, total bilirubin, direct bilirubin and transaminase declined respectively (P＜0.01). And the diameter of the total biliary duct became shorter (P＜0.01). Six of them returned to the normal level in three weeks. Early adverse events (in seven days) included mild acute pancreatitis (one case) and acute cholangitis (one case). Mean survival and patency of drainage were 186.93 days (54 to 426 days) and 156 days (51 to 426 days) respectively. All of them, 3 cases occured obstruction of stents (20%). Conclusion Implantation of uncovered selfexpandable metal stent through endoscope is an ideal therapy for distal malignant biliary obstruction.
目的 探讨如何预防腹腔镜胆囊切除术(LC)中的胆管损伤。方法 回顾性分析2006年1月至2008年12月期间在我院行LC的657例患者的临床资料，总结预防胆管损伤的经验。结果 651例患者完成LC，中转开腹手术6例(0.91%)，其中1例(0.15%)因Calot三角致密粘连误伤胆总管。术后胆囊床毛细胆管渗漏2例，每日经腹腔引流管引出胆汁性液体20～50 ml，7～10 d 治愈出院。术后578例（包括中转开腹6例）患者获随访,随访率为87.98%，随访时间为2～24个月, 平均14个月。23例患者剑突下隐痛, 4个月内均自行消失，其余患者均未发现并发症。结论 严格掌握手术适应证、正确仔细地处理Calot三角和适时中转开腹是预防LC术中胆管损伤的关键。
【Abstract】ObjectiveTo evaluate the therapeutic benefits of three styles of hernioplasties such as the traditional hernioplasty, the mesh only hernioplasty and the plug amp; mesh hernioplasty. MethodsThe traditional hernioplasty in 534 cases(583 sides), the mesh only hernioplasty in 57 cases(60 sides) and the plug amp; mesh hernioplasty in 51 cases(54 sides) were performed. The comparing studies on the operative time, the postoperative complications, the recurrent rate and so on were analyzed. ResultsThe average operative time of the traditional styles group was (34.26±4.56) min, which was significantly shorter than the mesh only group 〔(40.35±6.24) min, P＜0.05〕 and the plug amp; mesh group 〔(49.12±8.69) min, P＜0.01〕 respectively. This significant difference between the mesh only group and the plug amp; mesh group was also identified (P＜0.05). Postoperative complications in the traditional styles group, the mesh only group and the plug amp; mesh group were 1.12%, 1.75% and zero,respectively (Pgt;0.05). Recurrent rate in the traditional styles group was 5.99%(32/534), which was significantly higher than that of the mesh only and the plug amp; mesh group (no recurrence). The average hospitalizing time in the traditional styles group, the mesh only group and the plug amp; mesh group was (7.11±3.06) days，（5.38±2.53） days and （6.19±3.61） days, respectively, in which there was no significant difference among groups. The activityrecovering time in the traditional styles group was (16.98±4.35) days, which was significantly longer than （7.26±2.46） days in the mesh only group and （8.02±3.35） days in the plug amp; mesh group. Conclusion The mesh only hernioplasty or the plug amp; mesh hernioplasty have a lower recurrent rate comparing with that in the traditional hernioplasty, which should be much more popularly applied in the treatment of inguinal hernia.
ObjectiveTo compare difference of therapeutic effects between endoscopic frequency-doubled double pulse neodymium yttrium aluminium garnet (FREDDY) laser and endoscopic traditional mechanical lithotripsy in treatment of common bile duct stones (CBDs).MethodsThe clinical data of 207 patients with CBDs treated with ERCP and lithotripsy in the Ninth People’s Hospital Affiliated to Shanghai Jiaotong University School of Medicine from March 2009 to March 2019 were analyzed retrospectively, of which 71 cases treated by FREDDY (FREDDY group) and 136 cases treated by mechanical lithotripsy (mechanical group). The success rate of stone removal, operation time, postoperative hospitalization time, hospitalization cost, consumables cost, and complications were compared between the two groups.ResultsThere were no significant differences in the general condition and the preoperative clinical data between the two groups (P>0.05). There was no perioperative death in the two groups. There were no significant differences in terms of the postoperative routine laboratory biochemical indexes, consumables cost, hospitalization cost, and rates of the bleeding, postoperative pancreatitis, perforation and biliary tract infection between the two groups (P>0.05). Although the operation time of the FREDDY group was significantly longer than that of the mechanical group (P<0.05), the success rate of stone removal was significantly higher, the postoperative hospitalization time was shorter, the total complications rate and stone residual rate were significantly lower in the FREDDY group as compared with the mechanical group (P<0.05).ConclusionEndoscopic FREDDY laser lithotripsy has a better curative effect and less complications in treatment of large CBDs than mechanical lithotripsy, but operation time needs further to be improved.
