In order to investigate the causes, diagnosis, treatment, outcome and prevention of iatrogenic nerve injury in the neck, 8 cases with iatrogenic nerve injuries were analyzed. Among them, 5 cases were accessory nerve injury, 3 cases were brachial plexus injury. All of the cases were treated by surgical methods, including neurolysis, repair by direct suture, nerve graft and transposition. After 1-3 years follow up the effect was excellent in 2 cases who were accessory nerve injury, good in 5 cases, and poor in 1 case who was brachial plexus injury. It was concluded that high responsibility of surgeons and careful manipulation during operation were the key to prevention of nerve injuries.
Nerve injury following operation is one of the main causes of the iatrogenic peripheral nerve injury. In order to learn lessons from these cases, one hundred and seven cases of peripheral nerve injury complicated with the orthopedic operations were analyzed. Forty-four cases were cutting injury during operation, made up 41% of all cases and 27 cases were stretch and compression injury, made up 25%. The involved nerves included 41 radial nerves and 24 common peroneal nerves, composing 60.7% of all nerve injury. The operations responsible were mainly the bone and joint operations, which made up 81%. The cause, prophylaxis, diagnosis and treatment were discussed. The rich appropriate knowledge of anatomy and responsibility of the surgeon were emphasized in order to prevent the occurrence of complication. Once the injury was suspected, diagnosis should be made promptly and effective treatment should be performed in time.
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.
