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.
Three types of intestinal loops were used to reestablish the internal drainage of bile in 17 cases. The leeway derived from the peristaltic cycle of the intestinal loop for gastrointestinal reflux pressure, the cholangeitis after operation from reflux following choladocho-intestinal anastomosis could be avoided, and, naturally it had changed the traditional method of purèly blockade of the reflux, thus the result from treatment was far more satisfactory.
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 investigate the risk factors of infection after radiofrequency ablation in patients with liver metastases after choledochojejunostomy. Methods The clinical data of patients with liver metastases treated by radiofrequency ablation in our hospital from January 2010 to April 2022 were collected retrospectively and analyzed by univariate and multivariate logistic regression analysis. Results A total of 57 patients were included in the study, and the total number of postoperative infections was 19 (33.33%). Univariate logistic regression analysis showed that the tumor location, maximum tumor diameter, number of tumors, ablation times, and ablation duration were related to the occurrence of infection after radiofrequency ablation (P<0.01). The results of multivariate logistic regression analysis showed that the tumor location [OR=6.45, 95%CI (1.11, 37.35), P=0.037] and ablation duration [OR=1.49, 95%CI (1.16, 1.91), P=0.002] were independent risk factors for infection after radiofrequency ablation in patients with choledocho-jejunostomy. Conclusions For patients with metastatic liver cancer with a history of choledochojejunostomy, the tumor location and the duration of ablation are closely related to postoperative infection. We should strengthen the indivi-dualized management of such patients during and after operation should be strengthened to promote disease recovery.
The antireflux spur-valvewas originally designed for the Roux-Y cholenterostomy. It is made by plication of the two upper limbs of the "Y" after the removal of the seromusculature from the biliary limb, so that the conjoined wall-in-between will he compassed deviating to the biliary, side to form a spur value. It could successfully stop the reflux due to normal peristalsis or intestinal distension. This value was primarily used in choledochal cyst and biliary atresia for more than 100 cases, and also applielied to many other operations for perventing reflux, including: gastroesophageal refluk-Nissen fundoplication, colon replacement of esophagus, side to side shert-circuit of intestinal obstruction, and Kock scontinent ileoslomny. The detailed procedures were described.
