Objective To investigate the indications and clinical efficacy of combined application of laparoscope,choledochoscope and duodenoscope in the treatment of extrahepatic cholangiolithiasis.Methods The retrospective cohort study was adopted.The chnical data of 2 364 patients with extrahepatic cholangiolithiasis who were admitted to the First Hospital of Jilin University from January 2008 to December 2015 were collected.Of the 2 364 patients,861 patients had cholecystolithiasis combined with extrahepatic cholangiolithiasis and the diameter of common bile duct ≥ 8 mm,720 patients had cholecystolithiasis combine with extrahepatic cholangiolithiasis and the diameter of common bile duct ＜ 8 mm,783 patients had only extarhepatic cholangiolithiasis.In the patients diagnosed as cholecystolithiasis combined with extrahepatic changiolithiasis,laparoscopic cholecystectomy (LC) + laparoscopic common bile duct exploration (LCBDE) were applied to patients with the diameter of common bile duct≥8 mm,and the T-tube placement or primary suture was used intraoperatively according to the status of individualized patients;endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilation (EPBD) + LC were applied to patients with the diameter of common bile duct ＜ 8 mm.For patients with only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy,EST or EPBD was applied,and LCBDE was applied to patients with multiple stones and maximum diameter ＞ 2 cm and unsuitable for EST or EPBD.If residual stones were found after operation in patients with T-tube placement,choledochoscope was used to extract stone;otherwise,EST or EPBD was used.Treatment outcomes including treatment method,success rate of minimally invasive lithotomy,operation time,incidence of complication,duration of postoperative hospital stay and treatment expenses,and the results of follow-up including 1-,3-year recurrence rate of stones were recorded.The follow-up was done by outpatient examination and telephone interview till January 2016.All the patients were reexamined blood routine,liver function and color doppler ultrasonography of the abdomen at 1 month,3 months,6 months,1 year and 3 years after operation.Suspected residual cholangiolithiasis found by ultrasound was varified by computer tomography (CT) or magnetic resonanced cholangiopancreatography (MRCP) imaging examination.For patients with T-tube placement,CT scan and biliary photography were performed at 2-3 months postoperatively to determine whether residual stones existed and T tube could be pulled out.Measurement data were presented as mean (range).Results Of 2 364 patients,2 271 patients received minimally invasive lithotomy successfully.Of 861 patients of cholecystolithiasis combined with extrahepatic cholangiolithiasis and the diameter of common bile duct≥8 mm,836 succeeded in minimally invasive lithotomy,with a success rate of 97.10％ (836/861),the other 25 patients were converted to open surgery.Seven hundred and three patients of 836 patients received T-tube placement in LCBDE,and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 97 minutes (range,41-167 minutes),3.70％ (26/703),6.7 days (range,3.0-32.0 days) and 3.4 × 104 yuan (range,1.5 × 104-6.7 × 104 yuan),respectively.One hundred and thirtythree patients of 836 patients received primary suture,and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 89 minutes (range,39-123 minutes),3.01％ (4/133),4.1 days (range,2.0-17.0 days),2.1 × 104 yuan (range,1.6 × 104-3.4 × 104 yuan),respectively.Of 720 patients with the diameter of common bile duct ＜ 8 mm who underwent EST or EPBD + LC,687 succeeded in minimally invasive lithotomy,with a success rate of 95.42％ (687/720),the other 33 patients were converted to open surgery.The mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses of 687 patients were 101 minutes (range,69-163 minutes),2.91％ (20/687),5.6 days (range,2.0-15.0 days) and 2.8 × 104 yuan (range,2.0 × 104-6.4 × 104 yuan),respectively.In 783 patients with only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy,701 of 725 patients who were treated with EST or EPBD succeeded in minimally invasive lithotomy,with a success rate of 96.69％ (701/ 725),and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses of 701 patients were 47 minutes (range,11-79 minutes),2.28％ (16/701),3.7 days (range,2.0-19.0 days),1.7 × 104 yuan (range,1.3 × 104-5.5 × 104 yuan),respectively;47 of 58 patients who were treated with LCBDE succeeded in lithotomy,with a success rate of 81.03％ (47/58),and the mean operation time,incidence of complications,duration of postoperative hospital stay and treatment expenses were 124 minutes (range,94-170 minutes),8.51％ (4/47),7.9 days (range,5.0-21.0 days) and 3.8 × 104 yuan (range,2.3 × 104-7.9 × 104 yuan),respectively.Of 2 364 patients,2 207 were followed up for a mean time of 38 months (range,1-72 months).The 1-,3-year recurrence rates were 2.74％ (19/693) and 5.08％ (24/472) in patients receiving LC + LCBDE,3.10％ (21/677) and 5.69％ (30/527)in patients receiving EST or EPBD +LC for cholecystolithiasis combined with extrahepatic cholangiolithiasis.The 1-,3-year recurrence rates were 3.22％ (20/621) and 6.11％ (25/409) in patients receiving EST or EPBD + LC,7.32％ (3/41) and 11.11％(2/18) in patients receiving LCBDE for only extrahepatic cholangiolithiasis or recurrent stones after cholecystectomy.Conclusions It is safe and effective to treat extrahepatic cholangiolithiasis based on combined application of laparoscope,choledochoscope and duodenoscope,with choosing appropriate indications as the key to improve the therapeutic effect.Primary suture in the LCBDE is recommended because it can protect patients from T-tube placement.

ObjectiveTo investigate the clinical features of clonorchiasis diagnosed during biliary surgery, and to provide more comprehensive and effective information for the surgical treatment of clonorchiasis. MethodsA retrospective analysis was performed for the clinical data of 15 patients who were diagnosed with clonorchiasis during and after biliary tract surgery in our department from January 2013 to January 2016, and their clinical features were summarized. ResultsAll the 15 patients were male, among whom 5 once ate uncooked freshwater fish and shrimps. Of all patients, 8 underwent laparoscopic bile duct exploration and 7 underwent endoscopic retrograde cholangiopancreatography (ERCP). Adult Clonorchis sinensis was found in intraoperative or postoperative drainage. All the patients achieved clearance of Clonorchis sinensis after regular anthelmintic treatment. ConclusionIf bile duct exploration finds grey-black or bright-red melon seed-like floccules, clonorchiasis should be highly suspected. Intraoperative T-tube drainage is recommended, and if suspected Clonorchis sinensis is found after laparoscopic bile duct exploration and T-tube drainage or after ERCP and nasobiliary drainage, microbiological examination should be performed next. As for the patients with a definite diagnosis of clonorchiasis, they should not eat uncooked freshwater fish or shrimps and should be given regular anthelmintic treatment.

Objective To assess the efficacy and safety of autologous skin-grafting surgery ( ASGS) in the prevention of esophageal stenosis after complete circular endoscopic submucosal tunnel dissection ( ESTD) for early esophageal cancer. Methods Between January 2018 and March 2018, five patients with early esophageal cancer underwent complete circular ESTD and ASGS in Chinese PLA General Hospital. The skin-graft survival situation, and occurrence of esophageal stenosis and complications were observed by endoscopy follow-up. Results Complete circular ESTD and ASGS were successfully performed in all 5 patients, and no complications including perforation, bleeding, wound infection or stent migration occurred. The mean skin-graft survival rate was 86. 0％. Four patients did not experience esophageal stenosis over the mean follow-up of 9. 5 months. One patient experienced esophageal stenosis after operation, and underwent endoscopic balloon dilatation. No stenosis occurred in 8 months of follow-up. Conclusion ASGS is a safe and effective method to prevent esophageal stenosis after complete circular ESTD.

Objective:To evaluate the long-term efficacy and safety of a novel self-help inflatable balloon to prevent esophageal stenosis after extensive endoscopic submucosal dissection (ESD).Methods:Patients with early esophageal cancer or precancerous lesions, undergoing ESD in the First Medical Center of Chinese PLA General Hospital from January 2018 to December 2019 were included in the prospective study, who had post-ESD mucosal defect greater than 5/6 of the esophageal circumference and 30-100 mm in length. The self-help inflatable balloon was used to prevent esophageal stenosis after ESD. Mucosal defect of ESD was divided into grade 1 (≥5/6 and less than the whole circumference) and grade 2 (the whole circumference). The incidence of stricture, the time from ESD to the occurrence of stricture, the total number of endoscopic balloon dilations (EBD) or radial incision and cuttings (RIC), and other adverse events were observed.Results:A total of 27 patients met the including criteria with follow-up time of 14-38 months, including 3 patients of grade 1 and 24 of grade 2. The ulcer longitudinal length was 73.7±18.4 mm. The time of wearing balloons was 92.0±20.0 days. The overall frequency of stricture was 18.5% (5/27), and the stricture incidence of patients of grade 2 resection was only 16.7% (4/27). The median time from balloon removal to stricture was 17 days. To treat the stricture, two patients received 3 EBD sessions, and three other patients received 2, 1 and 2 RIC sessions, respectively. No balloon was removed in advance, and none had a perforation or delayed bleeding.Conclusion:The self-help inflatable balloon shows high efficacy and safety in preventing esophageal stenosis in patients with mucosal defect greater than 5/6 of the esophageal circumference and less than 100 mm in length after extensive esophageal ESD.
