AIM: To evaluate risk factors of biliary anastomotic complications (BACs) and outcomes according to type of biliary reconstruction. METHODS: A total of 33 consecutive adult living donor liver transplantation (LDLT) were reviewed, 17 of which had undergone Duct-to-Duct anastomosis (D-D). The remaining 16 patients received Roux-en-Y anastomosis (R-Y). The perioperative factors, such as the type of graft and the number of graft bile ducts, were analyzed retrospectively. RESULTS: The overall incidence of BACs was 39.4%. The incidence of BACs was significantly higher in the patients with than without neoadjuvant chemotherapy (71.4% vs 10%, P = 0.050). There was no signifi cant difference in the incidence of biliary leakage in patients with D-D vs those with R-Y. The incidence of biliary strictures following the healing of biliary leakage was significantly higher in D-D (60%) than in R-Y (0%) (P = 0.026). However, the incidence of BACs related bacteremia was signifi cantly higher in R-Y than in D-D (71.4% vs 0%, P = 0.008). In D-D, use of T-tube stent remarkably reduced the incidence of BACs, compared with straight tube stent (0% vs 50%, P = 0.049). CONCLUSION: Our experience showed an increase of BACs related bacteremia in the patients with R-Y. Therefore, D-D might be a preferred biliary reconstruction. However, the surgical refi nement of D-D should be required because of the high incidence of biliary strictures. Use of the T-tube stent might lead to a signifi cant reduction of BACs in D-D.

＜正＞ In the domain of orthopaedic surgery, a knowledge of three-dimensional （3-D） kneeprosthesis kinematics after Total Knee Arthroplasty （TKA） is highly important to validateinnovative prosthesis designs and different surgical strategies. In general, X-ray fluoroscopyis suitable for observing dynamic movement of knee prosthesis. Recently, a model-based

1997 International Symposium on Electromagnetic Compatibility

作者： Masaharu UCHINO yoshinobu HAYASHI Takashi SHINOZUKA Risaburo sato Electromagnetic Compatibility Research Laboratories Co.Ltd.

Given that amplitude probability distribution(APD) is an effective means of estimating the effects of electromagnetic disturbance on digital communications,we are now testing low-cost equipment for measuring APD at high resolution. The equipment combines multiple M-sequence counters having relatively prime periods and makes use of residue number systems(RNS) so that most circuits can be formed on one IC chip and a low-cost configuration can be achieved. In addition,the size of the discrete logarithm table here, which is essential to restoring the enumerated value from the bit pattern output of M-sequence counters,need be only 10 the size of a single M-sequence *** therefore arranging n units of this APD measuring equipment into a parallel configuration,processing speed can be increased by n times.
