  • Dynamic Observation of Biliary Tract after Surgery Via TTube Cholangiography in 170 Cases

    Objective To gain accurate imaging information of biliary tract after surgery. MethodsThe biliary tract of 170 cases after surgery had been observed dynamically from different directions for longer time. The results of data on biliary tract change were stored in disc, or picture. ResultsOf 170 cases, 120 cases were cured without any abnormal change on cholangiography, and then the Ttube was removed. Of another 50 cases, 30 cases revealed remnant stone on cholangiography, 9 cases showed inflammatory stricture of biliary tract, 4 cases displayed common bile duct tumor, and 7 cases had false fillingdefect. Then, the results were further confirmed by sonography, CT, choledochoscopy, and operation. Conclusion The dynamic observation of biliary tract by Ttube cholangiography after surgery is usual way that is handy, practical, painless, and economic.

  • Application of Routine or Selective Intraoperative Cholangiography in Laparoscopic Cholecystectomy

    Objective To explore whether the intraoperative cholangiography (IOC) should be applied in laparoscopic cholecystectomy routinely or selectively. Methods Data of routine IOC group (1 520 patients)and selective IOC group (457 patients)in laparoscopic cholecystectomy were collected and analyzed, including cholangiography time, success rate, common bile duct stones rate, open cholecystectomy rate, and hospital stay after operation. All IOC cases were performed by home-made cholangiography appliance or infusion needle. Results There were no significant differences between routine IOC group and selective IOC group on cholangiography time, success rate, open cholecystectomy rate, and hospital stay after operation (P>0.05). However, compared with routine IOC group, the common bile duct stones rate, anatomic variation rate, and iatrogenic damage rate were significantly higher in selective IOC group (28.25% vs. 13.43%, 10.71% vs. 7.43%, 2.05% vs. 1.02%, P<0.05). Conclusions For avoiding iatrogenic bile duct damage and residual stones, routine IOC should be applied in early-stage of laparoscopic cholecystectomy, and IOC should be applied selectively when the surgeon have LC technique at their finger ends.

  • The Compare and Analysis of Biliary Tract Stent Placing for Malignant Obstruction of Biliary Tract by Percutaneous Transhepatic Cholangiography or Endoscopic Retrograde Cholangiography

    ObjectiveTo compare the therapeutic efficacy of biliary tract stent placing for malignant obstruction of biliary tract by percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiography (ERC). MethodsPTC approach: choosing the expansion intrahepatic bile duct which had a large angle traveling with common bile duct at the ultrasound-guided, we performed bile duct puncture and inserted the drainage pipe into it, then stent was placed with 68 cases  (2 cases among the total were failure of ERC approach)  after a week drainage.  ERC approach:  inserting drainage tube into the common bile duct by duodenal endoscopic retrogradely,  the angiography showed obstruction site, the guide wire inserted through the obstruction site, then stent was placed along the guide wire with 53 cases. ResultsThe achievement ratio of stent placing by PTC was 100%(68/68),  and which by ERC was 96.2%(51/53). The complications  (bleeding,  bile leakage)  didn’t happen in two groups. 1-18 months (average 12.4 months) of follow-up, the died cases of PTC group and ERC group were 7 and 5 cases within 6 months, respectively; the survive cases of which were 17 and 9 cases after 18 months of treatment, respectively. ConclusionsThe biliary tract stent placing is a safe and effective method to the malignant obstruction of biliary tract patients who can not drainage tube be treated by operation. It can relieve biliary obstruction efficiency, and can increase live time and life quality for patients. We can choose the stent placing method by ERC for cases whose obstruction site is at the inferior of common bile duct or duodenal ampulla, and the cases whose obstruction site is at the above of hepatic porta should be chosen by PTC.

  • The Diagnosis and Treatment of Cholecystocolonic Fistula During Laparoscopic Chole-cystectomy

    ObjectiveTo explore the reliability and safety of diagnosis and treatment for cholecystocolonic fistula during laparoscopic cholecystectomy. MethodsData of patients with cholecystocolonic fistula in department of general surgery, Gansu provincial hospital from Jan 2002 to Dec 2015 were analyzed retrospectively. There were 112 cases diagnosed by routine intraoperative cholangiography from 11 472 laparoscopic cholecystectomy patients, including 33 males and 79 females, age from 58 to 84 years〔(67.4±12.6) years〕. ResultsOne hundred and twelve cases of cholecystocolonic fistula were diagnosed by routine intraoperative cholangiography in laparoscopic cholecystectomy. There were 105 cases of cholecystocolonic fistula performed laparoscopic cholecystectomy and colon repair, and 7 cases performed colostomy, no surgical complications occurred. Seventy cases were followed-up for 6-27 months〔(16.4±5.3)months〕after operation, no long-term complications occurred. ConclusionsThere is a lack of specific symptoms and special diagnosis for cholecystocolonic fistula before operation. Intraoperative cholangiography is a only objective method for diagnosis, and treatment of cholecystocolonic fistula by laparoscopic cholecystectomy and colon repair or colostomy is safe and reliable based on experienced laparoscopic skill.

  • Application of near infra-red fluorescence imaging in biliary surgery

    ObjectiveTo summarize the research progress of near infra-red fluorescence imaging (NIRFI) in biliary tract surgery, and to provide protection for improvements of therapeutic effect and safety of biliary tract surgery.MethodThe relevant literatures about studies on NIRFI in the biliary tract surgery in recent years were reviewed.ResultsThe NIRFI had been preliminarily used in the surgical treatment of benign and malignant biliary diseases, and had shown its unique value in cholangiography. It provided a new method for effectively avoiding surgical complications, shortening operation time, reducing the rate of conversion to open surgery, evaluating blood supply of bile duct and improving the safety of operation.ConclusionsNIRFI has achieved notable successes in treatment of biliary tract diseases. With future application of fluorescence imaging in near infra-red Ⅱ window and new specific fluorescence targeting molecules, this technique will highlight its more important values in biliary surgery.
