Objective To explore clinical effect of choledocholithotomy by laparoscopy-assisted choledochoelectroscopy and endoscopic retrograde cholangiopancreatography.Methods The clinical data of 126 gallstone and choledocholithiasis patients treated by laparoscopy-assisted choledochoelectroscopy(L group)and endoscopic retrograde cholangiopancreatography(E group)were analyzed retrospectively.In L group,the patients were performed LC and choledocholithotomy by laparoscopy-assisted choledochoelectroscopy directly,but in E group,the treatment procedures were finished by two steps.Firstly,the bile duct stones were carried out by ERCP,days later LC operations were performed.Between the two groups,the hospital days,costs,the rate of residual stone,the rate of bihary infection or panereatitis and the rate of stone recur were compared.Results In the two groups,hospital days were(6.5±0.3)d and(12.5±0.5)d,costs were(1.22±0.17)and(1.98±0.24)ten thousand yuan,the rate of residual stone was 0 and 5.3%,the rate of biliary infection or pancreatitis was 1.4%and 15.8%,and the rate of stone recur was 1.4%and 10.5%respectively.When compared each other the difference was statistically significant(t=2.48,1.96,χ2=4.32,4.90,8.79,all P＜0.05).Conclusion In patients with gallstone and bile duct stones,laparoscopy-assisted choledochoelectroseopy presented more predominances when compared with two steps methods.

BACKGROUND: Anterior cruciate ligament injury accompanied by unstable rotation is a hotspot in sports medicine. Further understanding of the anatomy and biomechanics of the anterolateral ligament can play a guiding significance for the recovery of knee joint rotational stability.
OBJECTIVE:To systematicaly review current literature on the anterolateral ligament of the knee and to understand the incidence, anatomy, morphology and histology of the anterolateral ligament as wel as mechanism of anterolateral ligament injury.
METHODS: The first author searched the PubMed, Medline, CNKI, Wanfang, VIP databases for articles specificaly addressing the anterolateral ligament. Data extraction related to the incidence, anatomy, morphometry, biomechanics, and histology of the anterolateral ligament and its relation to the “Segond” fracture was performed. The retrieve time ranged from 1878 to 2015. Totaly 362 literatures were retrieved, including 342 articles in English and 20 in Chinese. According to inclusive and exclusive criteria, 42 articles were included in result analysis.
RESULTS AND CONCLUSION:The occurrence rate of the anterolateral ligament ranges from 83% to 100%, and this range occurs because of smal discrepancies in the definition of the bony insertions of the anterolateral ligament. The anterolateral ligament originates anterior and distal to the femoral attachment of the lateral colateral ligament. It spans the joint in an oblique fashion and inserts between the fibular head and Gerdy tubercle of the tibia. Exact anatomic and morphometric descriptions vary in the literature, and there are discrepancies regarding the anterolateral ligament attachment to the capsule and lateral meniscus. The anterolaterial ligament is a contributor to the stability of tibial internal rotation, and histologicaly, it exhibits paralel, crimped fibers consistent with a ligamentous microstructure. The footprint of the anterolateral ligament has been shown to be at the exact location of the Segond fracture. The anterolateral ligament is a distinct ligamentous structure at the anterolateral plane of the knee, and it is likely involved in the control of excessive tibial internal rotation that can cause the Segond fracture.

The case of the nodular fasciitis was with a short history and rapid growth speed. The lesion was nodular, not encapsulated. Histologically, the fibroblasts proliferated actively, with some mitoses. The reality of the nodular fasciitis is the proliferation of fibroblasts and myofibroblasts. This disease is a benign lesion. It is very important to make a different diagnosis between this lesion and sarcomas. Ultrasonography and MRI are important assistants in diagnosis of nodular fasciitis. This disease could be effectively treated by local excision with a low recurrence rate and a satisfactory prognosis.
