may be facilitated by avoiding these drawbacks, and a survival rate of 80% may be achieved.--Thomas A. Angerpointner
T. Chiba. Z Kinderchir 43:95-98, (April), 1988. The authors investigated problems involved in relaparotomy, particularly ascending cholangitis, in 129 patients treated for biliary atresia since 1972. The occurrence of cholangitis after a relaparotomy for obstruction of the portahepatis, peritonitis, intestinal obstruction, portal hypertension, and external fistula was not increased. Relaparotomy must be considered particularly in those patients who develop cholangitis following the first hepatoportoenterostomy.-- Thomas A. Angerpointner Case Report of Biliary Atresia Associated With Preduodenal Portal Vein, Ventricular Septal Defect, and Bilobed Spleen. ]. Yamagiwa,
M. Ohta, K. Obata, et al. Z Kinderchir 43:108-109, (April), 1988. A case report of biliary atresia associated with a preduodenal portal vein is presented with a review of 27 similar cases previously reported. The occurence of associated anomalies in these 28 cases was 82%. Included were cardiovascular anomalies (71%), polysplenia (68%), malrotation of the gut (61%), situs inversus (22%), and duodenal atresia (9%). Developmental anomaly is considered to participate strongly in the etiology of biliary atresia combined with the preduodenal portal vein.--Thomas A. Angerpointner Gallbladder Contraction in Biliary Atresia. E. Weinberger, J.D.
Blurnhagen, and J.M. Odell. A JR 149:401-402, (August), 1987. This brief case report demonstrates that the prevalent axiom that gallbladder contraction on sonography rules out biliary atresia is false. The neonate in question was shown to eventually have biliary atresia, but the diagnosis had been somewhat delayed by the finding of gallbladder contraction. In this particular case, there was an essentially normal gallbladder that connected to the duodenum but did not connect to the liver. Gallbladder contraction on ultrasonography should not dissuade one from performing appropriate radionuclide imaging in pursuit of the diagnosis of biliary atresia.--Thomas V. Whalen Discordant Findings in Extrahepatic Bile Duct Atresia in Six Sets of T w i n s . P. Schweizer and J. Kerremans. Z Kinderchir 43:72-75,
(April), 1988. Current concepts in the etiology of biliary atresia are discussed and questioned in the light of discordant appearance of biliary atresia in six sets of twins. Although a genetic, inflammatory, immunologic, or toxic origin cannot be entirely excluded by these findings, the authors favor perinatal or postnatal ischemia as the etiologic factor in extrahepatic biliary atresia. The pros and cons of this theory are described in detaiL--Thomas A. Angerpointner Liver Transplantation for Biliary Atresia: Indications and Results.
J.B. Otte, Oh. Eucher, J.P. Latour, et al. Z Kinderchir 43:99-105, (April), 1988. This report is a review of the results of several pediatric surgical centers, and pertains to unsolved problems in biliary atresia. The authors conclude that a 5-year survival rate of 60% may be achieved in long-term follow-up, but a complete cure is observed in only 30%. Children who develop cirrhosis and portal hypertension can benefit only from liver transplantation. As a result of clinical experience, criteria are defined that should be met in the surgical treatment of biliary atresia. With respect to liver transplantation, the disadvantages of an external bile draining fistula to prevent cholangitis, extensive mobilization of the liver for hepatoportoenterostomy, and the disadvantages of reoperation are discussed. Liver transplantation
A New Method of Segmental Orthotopic Liver Transplantation in Children. R. Strong, T.H. Ong, P. Pillay, et al. Surgery 104:104-
107, (July), 1988. A new method of orthotopic segmental liver transplant is described, which involves dissecting the recipient liver off the inferior vena cava, which is left in situ. The donor hepatic vein with a vena cava cuff is anastomosed end-to-side to the inferior vena cava. The bifurcation of the recipient portal vein is opened for an end-to-end anastomosis to the donor portal vein. A small Carrel patch from the donor aorta is used for the celiac axis anastomosis. This technique was used for the transplantation of the left lateral segment of liver from an 80-kg adult donor into a 6.5-kg baby. The child is at home 12 months later with normal liver function.--John N. Schullinger Splenic Implants: Influence of Particle Size and Fibrin Fixation on Vascularization and Angioarchitecture. T. Foitzik, IV. Funk, H.
Roth, et al. Pediatr Surg Internat 3:263-268, (May), 1988. Splenic autotransplantation in tissue is a clinical method for partial preservation of splenic function following total splenectomy. Microangioarchitecture and vascular density of the implants as prerequisites for splenic function and the influence of particle size and fixation on neo- and revascularization have not been analyzed in detail. Homologous spleen particles of different sizes were implanted into transparent dorsal skinfold chambers in 30 golden hamsters. By means of intravital microscopy and computerized video analysis techniques, the process of capillary sprouting could be quantitatively analyzed in the awake animal over a 14-day period following implantation. Measurements included vessel diameter, vascular density, and tissue surface pO2. Based on the results obtained, the authors suggest limiting the size of splenic autografts to a volume that can be nourished by diffusion until the implants become vascularized. The use of fibrin glue for implant fixation does not interfere with vascularization of the graft.--Prern Puri Inguinal Hernias in Chinese Children. P.K.H. Tan, T.N. Tsang, and
H. Saing. Aust N Z J Surg 58:403-406, (May), 1988. The authors reviewed 542 patients with inguinal hernia in Chinese children over a 6-year period from the Department of Surgery at the University of Hong Kong. The age of the patient ranged from newborn to 12 years (63.6% were <2 months of age; 22 babies were premature). The sex ratio (male:female) was 1.6:1. The instance of inguinal hernias in Chinese children was given as 1% for the Hong Kong population. The authors comment that age distribution and incidence are similar to that those in Western countries, but that in this group of children, there were fewer premature infants. The sex difference was less marked than that of the Western population, and hernias were less frequently found on the right side. The absence of inguinal hernias in premature patients may be explained by the low survival of the premature babies in the Hong Kong population. The reason for differences in both male predominance and right-sided predominance for hernias is still unclear. The major morbidity of inguinal hernias was incarceration (23.6%). The authors noted that preoperative reduction was more commonly performed by the more experienced surgeons. They have consequently introduced a more enthusiastic policy for preoperative reduction, which they hope will minimize the complication rate for emergency herniotomy operations (25.6% as compared with 6.5% for elective herniotomy).-Patricia M.
