“…The rate of MRCP accurately detecting CBD is reported to be 38%-100% [30][31][32][33][34][35][36]. In addition, the diagnostic criteria of MRCP for PBM is equivalent to ERCP; however, the definitive detection rate thereof is reported to be 60%-100% [30][31][32][33][34][35][36][37][38]. The detection rates of PBM for adults and children are reported to be 82%-100% [32,34,35,37] and 40%-80% [30,31,33,[36][37][38], respectively.…”

“…The reason for false-positive diagnosis is often due to mistakenly diagnosing the overlap of the bile duct and pancreatic duct for maljunction. As MRCP does not possess such a high spatial resolution as X-rays, it is unclear how precisely it depicts complicated junctions [30][31][32][33][34][35][36][37][38].…”

Until now, there have been no practical clinical guidelines for congenital biliary dilatation (CBD). In this review article, the Japanese Study Group on Congenital Biliary Dilatation (JSCBD) propose to establish clinical practice guidelines for CBD. Because the evidence-based literature is relatively small, we decided to create guidelines based on the consensus of experts, using the medical literature for reference. A total of 20 clinical questions (CQs) were considered by the members of the editorial committee responsible for the guidelines. The CQs included the distinct aspects of CBD: (1) Concepts and Pathology (three CQs); (2) Diagnosis (six CQs); (3) Pancreaticobiliary Complications (three CQs); Treatments and Prognosis (eight CQs). Each statements and comments for CQs were made by the guidelines committee members. CQs were finally approved after review by members of the editorial committee and the guidelines evaluation board of CBD. These guidelines were created to provide assistance in the clinical practice of CBD management; their contents focus on clinical utility, and they include general information on CBD to make this disease more widely recognized.

“…Some researchers have already done this work, such as Zhang Hui-ming and his collaborators, they realizes remote control to the multi-media class-room equipment without network central control device [5][6][7]. The service software in this paper uses the Windows Completion Port, which is currently known as the most efficient Socket communication mechanism [8][9][10][11][12]. This paper put forward the hardware and software principles related to the Serial-Socket Bridge, and the working efficiency of the Bridge is discussed.…”

Serial port is an ancient hardware port but difficult to be replaced. There are still many special devices in the use of it. However, In the Microsoft Windows, the serial port programming is becoming increasingly difficult. This article not only describes the SerialSocket Bridge software structure of the Windows operating system, but also analyses the relevant hardware and software structure, and pointed out the possible bottlenecks. The software will map the serial port operation to the socket port operation, to replace the Serial-to-RJ45 Converter hardware, and will not take up the valuable physical network port resources. We tested the processor usage on a variety of different baud rates on an Intel i5 processor's computer. We have found that high baud rate serial transmission (more than 115200) with a certain time interval is more efficient than continuous low baud transmission. In addition, the operating environment is also important for runtime reliability.

“…Up to 80% of CMs present as cystic or fusiform dilatations of the common bile duct (types 1c and 1f) while biliary tree dilatation less commonly extends to the intrahepatic ducts (type 4) (1,6,7). A pancreaticobiliary maljunction (PBM); an abnormally premature union of the pancreatic and the biliary duct outside the duodenal wall, can be detected in most CM patients (8,9). By obstructing bile flow and allowing pancreatic juice reflux to the common bile duct, a PBM is thought to increase the risk for malignant transformation in the biliary epithelium (10).…”

Background. Incidence and long-term outcomes of choledochal malformations (CMs) in children remain unclear. Methods. Clinical characteristics, operative details, complications, and follow-up data were collected from eight pediatric surgical centers in Sweden, Norway, Denmark, and Finland, which also answered a questionnaire addressing management practices. Results. During 2000-2017, 126 pediatric CMs were diagnosed, corresponding an incidence of 1:37,400. Diagnostic, treatment, and follow-up practices varied markedly. Of patients with complete clinical data (n=119), 85% and 11% had type I and IV CMs and were managed by open hepaticojejunostomy at median age of 2.5 (interquartile range 0.46-5.8) years. Associated malformations were more common in fusiform and type IV (23%) than cystic CMs (8%, p=0.043). Pancreaticobiliary maljunction was more frequently confirmed in patients presenting with pancreatitis (26% vs. 7%, p=0.005) and with fusiform CMs (56% vs. 25%, p=0.001). Cholangitis/pancreatitis episodes, occurring in 12% during postoperative follow-up of 4.0 (2.0-7.9) years, associated with longer surveillance (OR 1.32, 95% CI 1.13-1.54, p<0.001). However, only two thirds of centers continued follow-up until adulthood. No malignancies were reported. Conclusions. CM incidence was higher than traditionally reported among Western populations. Although open hepaticojejunostomy carries good short-term outcomes, long-term morbidity is noteworthy. Standardized evidence-based management strategies and long-term follow-up are encouraged.

Significance of imaging modalities for preoperative evaluation of the pancreaticobiliary system in surgery for pediatric choledochal cyst

Abstract: Combining MRCP and IOCP can provide satisfactory pancreaticobiliary anatomical information for surgical planning for pediatric CC, with hepatic duct strictures evaluated more accurately by IOCP.
