The secondary anastomotic stenosis is often occured from the repair and reconstructive operation of the injured bile duct. It is difficult to treat and the outcome is serious. In order to prevent this complication, the fibrin glue instead of traditional suturing technique combined with inner support was used. Fifty-four hybrid dogs were divided into 3 groups. Group A received Roux-en-y choledochojejunostomy with fibrin glue; group B received Roux-en-y choledochojejunostomy, with a fibrin glue combined support left permanently in the bile duct and group C received Roux-en-y choledocholejejunostomy with fibrin glue combined a support left temporarily in the bile duct. The amount of collagen in the scar was measured at 3/4, 3, 6, 9, 12 months respectively after operation. The results showed: 1. the mature period of scar was shortened from 12 months to 9 months when fibrin glue instead of suture was used in choledochojejunostomy; 2. the mature period of scar was further shortened from 9 months to 6 months when fibrin glue combined with inner support instead of fibrin glue was used in choledochojejunostomy. The conclusions were as follows: 1. fibrin glue could facilitate the healing of wound by inhibiting the formation of scar and accelerrate the maturation of scar; 2. when the inner support was used with fibrin glue in the operation, the mature period of scar could be further shortened; 3. the mechanism of action of the fibrin glue included minimizing the injury, avoiding foreign-body reaction, modifying organization of hematoma, preventing formation of biliary fistular and enhancing intergration and cross-linkage of collagen.
目的 探讨金属银夹标记胆道通道，利用胆道镜技术治疗胆肠吻合术后肝胆管结石复发的可行性、安全性和有效性。方法 回顾性分析大连市友谊医院47例胆管结石行胆肠Roux-en-Y吻合术患者的资料，在空肠盲袢或输出袢处使用银夹作标志，术后通过胆道镜行胆管残留结石或复发结石或狭窄的治疗。结果 11例术后胆管残留结石和5例残留结石合并胆管狭窄者经T管窦道行胆道镜探查、取石及肝胆管狭窄的治疗而治愈。2例结石复发的患者根据空肠的金属银夹标记物，在数字减影血管造影（DSA）下进行穿刺置管建立胆道镜通道，通过胆道镜成功取出了结石，避免了再手术。结论 发挥胆道镜技术治疗肝胆管结石的优势，经以银夹标志的胆道通道，可望成为治疗胆肠吻合术后复发结石手段的有益补充。

Objective To observe the effects of basic fibroblast growth factor (bFGF) on wound healing of bilioenteric anastomosis as to prevent postoperative biliary strictures. Methods A model of choledochodundenostomy in 31 dogs were constructed at first, then bFGF was administered on the local anastomosis(bFGF group) for 1 week after the operation as compared with sodium chloride solution(control group). Both groups were observed with light microscope(HE,Masson staining) and electron microscope 3 days, 1 and 3 weeks and 3 and 6 months after the operation（n＝3）. Hydroxyproline was measured at the same time. Results bFGF group healed more quickly compared with control group. Good function of cells were detected by electron microscope. Better mucosa epithelia, fibroblast,and capillary vessel proliferation were detected by histological observation in bFGF group. In bFGF group, collagen fibers were arranged orderly. Three weeks after operation, collagen fibers in control group were orderless and in whirlpool. Hydroxyproline of bFGF group was lower than that of control group(P＜0.05）.Conclusion bFGF administered in local anastomosis is an effective method to prevent postoperative anastomotic stenosis.
Objective To explore surgery strategy of reoperation for type Ⅳa congenital choledochal cyst. Methods The patient was a 20-year-old female with repeated right upper abdominal pain and fever for more than 1 year and aggravation for more than 1 month, and the choledochal cyst excison was performed 15 years ago. The MRI revealed that a huge cyst located in the left lobe of liver, with multiple intrahepatic calculus. The patient was diagnosed with a type Ⅳa congenital choledochal cyst and choledochojejunostomy later and the intrahepatic dilated bile duct was untreated. Results The cystic dilatation of the intrahepatic bile duct was confirmed during the reoperation, and the multiple stones with pus formation were seen, the color of the right liver was normal and the anatomical left hemihepatectomy was performed. The original anastomosis had no stenosis then was preserved. An about 1.5 cm length of extrahepatic bile duct was dissociated from the upper of anastomosis, and the extrahepatic bile duct was cut open and explored with a choledochoscope. The T-tube drainage was performed following removing the stone. The patient recovered well and was discharged smoothly following the surgery. The cholangiography 6 weeks later revealed that the biliary tract was patency and there was no residual stone. There was no jaundice or fever afterwards. Conclusion Complete excision of choledochal cyst and hepaticoduodenostomy is widely accepted as a standard surgery for type Ⅳa congenital choledochal cyst.
Objective To investigate the clinical value of " O”continuous biliary-enteric anastomosis combined with percutaneous transhepatic cholangial drainage (PTCD) in pancreaticoduodenectomy (PD). Methods The clinical data of 35 patients with PD who were admitted to Xinyang Central Hospital from June 2015 to June 2017 were retrospectively analyzed. Results All patients completed the " O” continuous biliary-enteric anastomosis combined with PTCD without perioperative death. ① The preoperative indwelling time of PTCD tube was (13.24±3.39) d, total bilirubin (TBIL) was (363.67±12.26) μmol/L on admission and (155.59±17.63) μmol/L on preoperative after PTCD, respectively. ② The operative time was (231.46±18.69) min, the intraoperative blood loss was (158.30±31.33) mL, the diameter of the hepatic ductal segment was (1.3±0.2) cm, and the duration of the " O” continuous biliary-enteric anastomosis was (7.31±1.52) min. ③ After surgery, the indwelling time of PTCD tube was (8.13±1.49) d, the hospitalization time was (27.31±5.49) d. Biliary leakage occurred in 1 case, pancreatic fistula occurred in 5 cases (3 cases of biochemical sputum and 2 cases of B-stage pancreatic fistula), abdominal infection occurred in 2 cases, pneumonia occurred in 3 cases, wound infection occurred in 2 cases. No postoperative biliary-enteric anastomosis stenosis, biliary tract infection, and intra-abdominal hemorrhage occurred. There was no laparotomy patients in this group and all patients were discharged. ④ All patients were followed-up for 180 days after surgery. No death, bile leakage, biliary-enteric anastomotic stenosis, biliary tract infection, pancreatic fistula, gastro-intestinal leakage, and abdominal infection occurred. One case of delayed gastric emptying and 2 cases of alkaline reflux gastritis were cured after outpatient treatment. Conclusions The preoperative PTCD can improve the preoperative liver function and increase the security of PD. " O” continuous biliary-enteric anastomosis is simple, safe, feasible, and has the function of preventing biliary-enteric anastomosis stenosis. For severe jaundice patients with blood TBIL >170 μmol/L, the " O” continuous biliary-enteric anastomosis combined with PTCD is an alternative surgical procedure for PD.
目的 探讨先天性胆总管囊肿(congenital choledochal cyst,CCC)术式选择与疗效的关系。方法 对1989年至1998年间38例CCC手术治疗病例进行回顾性研究。结果 38例中行胆肠Roux-Y吻合术20例，肝总管十二指肠高位大口吻合术18例。术后随机获随访31例。13例胆肠Roux-Y吻合术后随访3～7年，发现5例并发十二指肠溃疡，3例并发胆道逆行感染。18例肝总管十二指肠高位大口吻合术后随访2～5年，发现1例并发胆道逆行感染，无1例并发十二指肠溃疡。结论 由于肝总管十二指肠高位大口吻合术后远期并发十二指肠溃疡发生率较低，其与胆肠Roux-Y吻合术相比，是提高CCC患儿术后远期生活质量较理想的术式。
