A shortage of small pediatric organ donors has led to the development of reduced size liver transplantation in children. However, the discrepancy between donor and recipient weight can limit the use of this procedure despite transplantation of the left lobe only. Monosegmental liver transplantation using segment III only was recently described. We report here the case of an 11 month old, 6.9 kg boy who received another monosegmental graft (segment II) from a 78 kg donor on an urgent basis. Because of the lack of parenchymal landmarks between segments II and III, sterile methylene blue solution was injected into the portal vein of segment III: parenchyma of this segment colored immediately and was resected accordingly. Three and a half years later, the growth, development, and nutrition of this child were normal. This procedure seems to be helpful when the left lobe of the graft is obviously too large.
8 cases of splenic cysts are reported: treatment was surgical in 4 large cysts (greater than 5 cm, 3 epidermoids and 1 pseudocyst), and non-operative in 4 small cysts (less than 5 cm, 3 post-traumatic pseudocysts and 1 congenital cyst, probably epidermoid). Follow-up was over a period of 3 months to 7 years. 3 among the 4 post-traumatic pseudocysts were followed up by ultrasound until resolution (3 months to 3 years), and 1 large pseudocyst was operated on due to rupture following benign trauma. 3 large cysts were epidermoid in origin, 1 was electively operated, and 2 were discovered and operated on because of complications (rupture, infection). Only one total splenectomy was performed; surgery preserved the spleen in all other cases; but 1 epidermoid cyst presents now with a recurrence. Based on this experience, we suggest frozen section of the cyst wall during surgery, to decide the type of partial splenectomy to be performed: total cystectomy or marsupialization.
The aim of this study was to analyze the impact of TAC on medium term (three-yr follow-up) renal function in pediatric liver transplant (OLT) recipients. Glomerular and tubular indices were retrospectively analyzed in 24 consecutive OLT pediatric recipients on TAC. CrCl increased significantly each month post-OLT (p = 0.003), with a trend toward significance between pre-OLT and 36 months (p = 0.17). There was no correlation between CrCl and TAC troughs (p = 0.783). Sixteen percent of patients had CrCl <60 mL/min/1.73 m(2) pre-OLT vs. none at 36 months post-OLT. TRP values were normal throughout the study. UPr/Cr decreased insignificantly over time and correlated significantly with TAC trough levels (p = 0.031). UCa/Cr values normalized by the third-month post-OLT, decreasing significantly over the time (p = 0.000) but did not correlate with TAC troughs. At three months post-OLT, 65.2% of patients needed antihypertensive therapy, and no patients needed more than one antihypertensive treatment after one yr. Despite nephrotoxic side effects in the early postoperative phase, this study shows that 65.5% patients had a normal renal function by three yr post-OLT. Tubular indices correlated with TAC trough levels.
Percutaneous cholecystography was performed on 13 children who had biliary system abnormalities: two had biliary hypoplasia, five had sclerosing cholangitis, three had cirrhosis, two had distal choledochal obstruction, and one had an obstructed portoenterostomy. In 12 patients transcholecystic cholangiography showed, without significant complications, the intra-and extrahepatic bile ducts. In one patient with primary sclerosing cholangitis, the intrahepatic bile ducts were not opacified satisfactorily; dilatation of the gallbladder required surgical drainage. The transcholecystic technique is indicated when the intrahepatic bile ducts are either mildly dilated or not dilated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
