It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

PURPOSE: The megacolon after repairing an anorectal malformation is not a rare complication, and there is much controversiy on the causes, the treatment of choice and the results after a longterm follow-up. We present 5 cases of a megacolon after the repair of an anorectal malformation, which were controlled with either a surgical resection or conservative treatment. METHODS: Five patients with a megacolon after the repair of an anorectal malformation were studied. A retrospective chart review was done and fecal continence was evaluated with an individual interview. RESULTS: All five patients initially underwent conservative treatment with laxatives and/or enemas. One Patient responded well to conservative treatment and the diameter of the bowel reduced to normal size. Another patient responded to conservative treatment after correcting the location of the anus. Three patients needed a surgical resection and one of those needed a further procedure to correct the anal location. After the surgical resection of the megacolon and/or correction of the anus (one out of the three patients), they soon reported an almost normal bowel habit. CONCLUSION: The first step in treating a megacolon after repairing an anorectal malformation was conservative treatment. However patients without an adequate response to conservative treatment are best managed with a surgical resection. The cause of the megacolon is now under investigation and the lack of adequate management after repair is one of the subjects.

Pseudoaneurysm of splenic artery may arise from a vascular erosion by the inflammatory processes around the splenic artery, particularly in acute pancreatitis and chronic pancreatitis, which may cause rupture of pseudoaneurysm and life threatening hemorrhage. Collective experience with this massive hemorrhage is attended by a high mortality rate even with prompt therapy, and conservative management is associated with an almost 100 per cent of mortality rate. Identification of the bleeding site at laparotomy may be exceedingly difficult, which makes the preoperative detection of bleeding source desirable. Peripancreatic vascular lesions can be identified by angiography, and in selected cases the risk of urgent operation to control massive hemorrhage may be obviated by embolization. The authors have recently experienced a case of ruptured splenic artery pseudoaneurysm combined with a pancreatic pseudocyst in a 6 years old boy. A bolus enhanced CT scan and angiography were essential to confirm these complications of pancreatic pseudocyst. We managed this child successfully with an urgent procedure of transcatheter arterial embolization and another elective surgery of pancreatic pseudocyst.

Subarachnoid hemorrhage from a ruptured intracranial aneurysm during pregnancy is rare but results in significant maternal and fetal mortality. The authors report 5 cases of anesthetic experience with pregnant patients undergoing a surgical aneurysmal clipping out of 2,100 patients with subarachnoid hemorrhages due to a ruptured cerebral aneurysm from 1972 until May 2001. All of the patients were diagnosed with a subarachnoid hemorrhage by a brain CT and cerebral angiography. Anesthetic modality and surgical timing should be adjusted by gestational age and the physiologic changes which accompany the pregnancy and the potential risks to the fetus from investigating and treating the mother. Anesthetic goals for this patient include maintenance of uteroplacental perfusion, and fetal as well as maternal well-being. We gave a general anesthesia with isoflurane-nitrous oxide and fentanyl. The patients were monitored with standard monitorings for surgical repair of a cerebral aneurysm and perioperative fetal heart monitoring. All of the five patients recovered well from the surgical aneurysmal repair. After surgical aneurysmal repair, 4 patients maintained their pregnancies and had their babies delivered at term through a cesarean section in 3 patients and transvagina in 1 patient. However, 1 patient who presented persisting hypertension experienced an intrauterine fetal death at 25 weeks of gestational age.

The prognostic factors for extrahepatic biliary atresia (EHBA) after Kasai portoenterostomy include the patient's age at portoenterostomy (age), size of bile duct in theporta hepatis (size), clearance of jaundice after operation (clearance) and the surgeon's experience. The aim of this study is to examine the most significant prognostic factor of EHBA after Kasai portoenterostomy. This retrospective study was done in 51 cases of EHBA that received Kasai portoenterostomy by one pediatric surgeon. For the statistical analysis, Kaplan-Meier method, Logrank test and Cox regression test were used. A p value of less than 0.05 was considered to be significant. Fifteen patients were regarded as dead in this study, including nine cases of liver transplantation. There was no significant difference of survival to age. The age is also not a significant risk factor for survival in this study (Cox Regression test; p = 0.63). There was no significant difference in survival in relation to the size of bile duct. However, bile duct size was a significant risk factor for survival (Cox Regression test; p = 0.002). There was a significant difference in relation to survival and clearance (Kaplan-Meier method; p = 0.02). The clearing was also a significant risk factor for survival (Cox Regression test; p = 0.001). The clearance of jaundice is the most significant prognostic factor of EHBA after Kasai portoenterostomy.

In hepatoblastoma, encouraging cure rates have been achieved with recent advances in chemotherapy and surgical techniques. The aim of this study is to evaluate the role of combined therapeutic modalities and surgical resection in hepatoblastoma. Fifteen cases of hepatoblastoma were treated from January 1993 to August 2000. Six patients had resectable tumors at initial diagnosis. All underwent surgical resection and in four patients postoperative adjuvant chemotherapy was needed. Nine out of 15 patients had unresectbale tumors at initial diagnosis, and preoperative chemotherapy was applied. There was one operative mortality and 14 patients showed good prognosis after surgery. Although various treatment modalities should be combined for the unresectable hepatoblastoma, surgical resection remains the major curative procedure.

Evaluation of the sacrum in anorectal malformations (ARMs) is important because of the frequent association with ARMs and functional outcome after correction of ARMs. Sacral defects are not easily detected because of immaturity of sacrum in children and overlooking of pediatric surgeons. The authors utilized the sacral ratio in normal children and patients with ARMs. In normal children, the mean true sacral ratio and mean sacrococcygeal ratio were 0.60+/-0.08 and 0.72+/-0.13 respectively. Sacral ratio was not correlated with age and did not changed with age in same patient. However, true sacral ratio and sacrococcygeal ratio were significantly lower in patients with high type ARMs than those of normal children (p<0.001). There was no difference between patients with low type ARMs and normal children. These results suggest that abnormal sacrums are more frequently encountered in patients with high type ARMs than in normal children, and that true sacral ratio and sacrococcygeal ratio can be used in the evaluation of the abnormal sacrum.

Femoral hernias are very uncommon in children and very easily misdiagnosed. During a period of three years, three children of femoral hernia were treated by one pediatric surgeon at Severance Hospital. Only one case was diagnosed correctly before surgery; the other two were thought to be either an indirect inguinal hernia or groin mass. Only one patient had curative hernioplasty (McVay hernioplasty) at the first operation; the other two did not have curative hernioplasty at the first operation. Femoral hernia in childhood is a challenging clinical problem because of its rarity and similar clinical presentation as indirect inguinal hernia. The frequency with which an incidental indirect inguinal hernia sac or patent processus vaginalis can be found at surgery can perpetuate a misdiagnosis. The absence of an expected indirect inguinal hernia sac or an apparent recurrence of an indirect inguinal hernia should lead to consideration of possible femoral hernia.

Neuroblastoma arises from the embryonic tissue of adrenergic rest. It is commonly found in children but mostly in nonrenal tissue. We present a case of intrarenal neuroblastoma which was initially mistaken as Wilms' tumor in a 18 months-old girl treated with radical nephrectomy with postoperative adjuvant chemotherapy. The location of mass within the kidney cannot always indicate that it is Wilms' tumor. Sometimes neuroblastoma from adrenal or retroperitoneal space often compresses or invades directly the kidney and it can also origanate in the kidney. Important clinical aspects in differenctialting neuroblastoma and Wilms' tumor along with review of literatures are discussed.

BACKGROUND: Balloon kyphoplasty is the new technique that helps to decrease the pain and improve mobility as well as restore the vertebral body height and kyphotic curve in fractured vertebrae. We evaluated the outcome of balloon kyphoplasty in the reduction of vertebral body height, kyphotic curve and clinical improvement in the patients with painful vertebral compression fractures. METHODS: From July 2002 to February 2005, 84 levels of vertebral compression fractures in 66 patients were treated with balloon kyphoplasty. The assessment criteria were the changes over time in visual analogue scale (VAS) and mobility score. We evaluated the vertebral body height and kyphotic curve at preoperative 1 day and postoperative 1 day. RESULTS: Procedures were performed in 66 patients with a total of 84 affected vertebral bodies. The anterior wall height was restored in 74 / 84 (88%) levels with a mean increment of 2.9 mm, and the mid-vertebral body height was restored in 79 / 84 (94%) levels with a mean increment of 4.2 mm. Kyphosis correction was achieved in 60 / 84 (71.4%) from 10.1 degrees to 7.5 degrees. Pain intensity reduced by 60% in one day after operation and by 75-85% in later time. Mobility scores of all patients were improved immediately after the procedure. Cement leakage occurred in 3 levels but there was no clinical problem. CONCLUSIONS: Kyphoplasty is an efficient and safe treatment of painful vertebral compression fracture in pain relief, mobility improvement, and reduction of deformity.
