Results The classification of 27 cases: 5 cases of type Ⅰ, 18 cases of type Ⅱ, 2 cases of type Ⅲ, 2 cases of type Ⅳ. Diagnosis: 11 cases were immediately discovered at the time of the initial operation, include 1 case of type Ⅰ, 8 cases of type Ⅱ, 1 case of type Ⅲ, 1 case of type Ⅳ; 10 cases were detected in early stage after the initial operation, include 2 cases of type Ⅰ, 7 cases of type Ⅱ, 1 case of type Ⅲ; 6 cases were detected in delayed stage after the initial operation, include 2 cases of type Ⅰ, 3 cases of type Ⅱ, 1 case of type Ⅳ. Treatment effect: 17 cases for excellent, 5 cases for good, 4 cases for bad, the well recover rate was 84.6% (22/26). One case died after operation. A total of 26 cases were followed up, 1 case was lost to follow up. During the follow-up period, bile leakage occurred in 3 cases, infection of incision occurred in 2 cases, cholangitis occurred in 3 cases, and bile duct stricture occurred in 2 cases. Conclusions The best time of repairing for the iatrogenic bile duct injuries is at the time of the initial operation or early stage. According to the type of injury and the time of the injury was diagnosed, timely and effective treatment by intervention and (or) surgery is the key.
ObjectiveTo explore the cause, clinical diagnosis and treatment, and prevention strategies of iatrogenic bile duct injury (IBDI). MethodsBy means of literature retrieval, the clinical diagnosis and treatment measures of patients with IBDI were summarized. ResultsThe related risk factors of IBDI include man-made factors, the local anatomy variation factors, and pathological factors. According to the damage diagnosis time and local pathological state, the repair operations such as bile duct suture repair, biliary tract end to end anastomosis, bile duct jejunum Roux-en-Y anastomosis, bile duct jejunum Roux-en-Y anastomosis, and jejunal artificial valve forming, or liver resection, and liver transplantation were performed. Moreover, it was also available that biliary stent or papillary balloon dilation through ERCP for the bile duct distal stricture. ConclusionsIt is important that prevention of IBDI. Operation should pay attention to upper abdominal operation prior to the implementation of the correct understanding of IBDI. In case of IBDI, the reasonable repair operation mode should be choose according to the damage types and time, and it can significantly improve the treatment effect and quality of life of patients.
Objective To explore the effectiveness of thumb blocking technique through closed reduction of ulnar Kirschner wire threading in the treatment of Gartland type Ⅲ supracondylar humerus fractures in children. MethodsThe clinical data of 58 children with Gartland type Ⅲ supracondylar humerus fractures treated with closed reduction of ulnar Kirschner wire threading by thumb blocking technique between January 2020 and May 2021 were retrospectively analyzed. There were 31 males and 27 females with an average age of 6.4 years ranging from 2 to 14 years. The causes of injury were falling in 47 cases and sports injury in 11 cases. The time from injury to operation ranged from 24.4 to 70.6 hours, with an average of 49.6 hours. The twitch of ring and little fingers was observed during operation, the injury of ulnar nerve was observed after operation, and the healing time of fracture was recorded. At last follow-up, the effectiveness was evaluated by Flynn elbow score, and the complications were observed. Results There was no twitch of the ring and little fingers when the Kirschner wire was inserted on the ulnar side during operation, and the ulnar nerve was not injured. All children were followed up 6-24 months, with an average of 12.9 months. One child had postoperative infection in the operation area, local skin redness and swelling, and purulent secretion exudation at the eye of the Kirschner wire, which was improved after intravenous infusion and regular dressing change in the outpatient department, and the Kirschner wire was removed after the initial healing of the fracture; 2 children had irritation at the end of the Kirchner wire, and recovered after oral antibiotics and dressing change in the outpatient department. There was no serious complication such as nonunion and malunion, and the fracture healing time ranged from 4 to 6 weeks, with an average of 4.2 weeks. At last follow-up, the effectiveness was evaluated by Flynn elbow score, which was excellent in 52 cases, good in 4 cases, and fair in 2 cases, and the excellent and good rate was 96.6%. ConclusionThe treatment of Gartland type Ⅲ supracondylar humerus fractures in children by closed reduction and ulnar Kirschner wire fixation assisted with thumb blocking technique is safe and stable, and will not cause iatrogenic ulnar nerve injury.
31 cases of iatrogenic cholangic injury reported. 28 cases followed from 9 months to 6 years. iatrogenic cholangic injury is not an uncommon occurence main cases are inregular procedures, and carelessness in this group, only 9 cases were found intraoperatively. The main manifestations after injury were aggravating jaundice and/or bilious peritonitis. Symptoms, signs, B-type ultrsound and sometimes ERCP were used for diagnosis. Once the injury ascertained ends are the best treatment, an alternative Roux-Y Cholangiojejunostomy was also commonly used. In this group, 4 cases received the first methos and all with good results; 23 patients treated by the second methos, 17 were uneventful, 4 experienced more or less abdomenal pain, 2 suffered difinite repeated cholangitis and another 1 died.
Object To evaluate the significance of double common bile duct （DCBD） in hepatobiliary surgery. Metheds The data of diagnosis and treatment of two patients with DCBD in our hospital between Jul. to Dec. 2010 were analyzed retrospective， and the related literatures were reviewed. Results The right hepatic bile duct of DCBD due to mistaking it for cystic duct in 1 case was accidental injuried during laparoscopic cholecystectomy. Another example，the DCBD was confirmed by intraoperative exploration and choledochoscopic examination， at the same time with chole-dochal cyst， anomalous pancreaticobiliary ductal junction （APBDJ）， primary hepatolithus， and choledocholith， and then operation was performed. Two cases were typeⅤb of DCBD. A total of 32 English literatures were reviewed. Since the beginning of 1932 English literature had reported 100 cases of DCBD. The type Ⅱand typeⅢwere the most common type of DCBD， and the typeⅤonly 10 cases. There were 27 cases of DCBD in twenty-five Chinese articles from 1994 to 2012. The typeⅤwas the most common type of DCBD. The accessory common bile duct （ACBD） opening in the duod-enum， gastric， and pancreatic duct were the most common. The common complications included stone， APBDJ， choled-ochal cyst， tumor etc. Conclusions DCBD is a very rare anatomic variation of extrahepatic bile duct， often accompanied by calculus of bile duct and common bile duct cyst， APBDJ， and other biliary anatomy abnormality， and potentially carci-nogenic potential. The existence of DCBD may increase the risk of iatrogenic bile duct injury and complexity of biliary operation. In view of this， this abnormality of extrahepatic duct should be paid with close attention during operation.
Objective The intercellular adhesion (ica) gene of Staphylococcus epidermidis (SE) is a key factor to bacterial aggregation, to analysis the genotype of iatrogenic SE and to explore the effect of iatrogenic SE ica operon on theformation of bacterial biofilm on the surface of polyvinyl chloride (PVC). Methods Fifty-six cl inical isolates of iatrogenic SEwere selected, and PCR and gene sequencing were used to detect the genes related with bacterial biofilm formation. The genes contained 16S rRNA, autolysin (atlE), fibrinogen binding protein (fbe), and icaADB. The bacteria suspension of 1 × 105 cfu/mL iatrogenic SE was prepared; according to the test results of target genes, the PVC material and the genotype of icaADB+, atlE+, fbe+ strains were co-cultivated as the ica positive group; the PVC material and the genotype of icaADB-, atlE+, fbe+ strains were co-cultivated as the ica negative group. The thickness of biofilm and bacterial community quantity unit area on PVC materials were measured by confocal laser scanning microscope, and the surface structure of biofilm formation was observed by scanning electron microscope (SEM) at 6, 12, 18, 24, and 30 hours. Results The positive rate of 16S rRNA of iatrogenic SE strains was 100% (56/56). The genotype of icaADB+, atlE+, and fbe+ strains accounted for 57.1% (32/56). The genotype of icaADB-, atlE+, and fbe+ strains accounted for 37.5% (21/56). The sequencing results showed that the product sequences of 16S rRNA, atlE, fbe, and icaADB were consistent with those in GenBank. With time, no significant bacterial biofilm formed on the surface of PVC in ica operon negative group. But in ica operon positive group, the number of bacterial community was gradually increased, and the volume of bacterial biofilms was gradually increased on the surface of PVC. At 24 hours, mature bacterial biofilm structure formed, and at 30 hours, the volume of bacterial biofilms was tending towards stabil ity. The thickness of biofilm (F=6 714.395, P=0.000) and the bacterial community quantity unit area on PVC materials (F=435.985, P=0.000) in ica operon positive groupwere significantly higher than those in ica operon negative group. Conclusion Iatrogenic SE can be divided into 2 types ofica operon negative and ica operon positive bacteria. The iatrogenic SE ica operon can strengthen bacterium biofilm formation capabil ity on PVC materials, bacterium community quantity, and thickness of biofilm, it plays an important role in bacterium biofilm formation on PVC materials.
