RESUMO
The aim of this study was to assess the long-term results of liver transplantation (LT) in pediatric patients with unresectable hepatoblastoma (HB) or hepatocellular carcinoma (HCC) with special reference to the risk of tumor recurrence. We retrospectively analyzed data from 46 HB and 26 HCC patients who underwent LT between 1990 and 2022. In HCC patients, we compared outcomes depending on donor type. We evaluated the impact of a number of risk factors on recurrence-free survival after LT. Estimated patient survival after 5, 10, and 15 years was 82%, 73%, and 73% in the HB group and 79%, 75%, and 75% in the HCC group, respectively (p = 0.76). In the HCC group, living donor LT (LDLT) and deceased donor LT (DDLT) provided similar patient survival (p = 0.09). Estimated recurrence-free survival in patients who had three or fewer risk factors was significantly better than in patients with more than three risk factors (p = 0.0001). Adequate patient selection is necessary when considering LT for primary liver tumors in children. The presence of more than three risk factors is associated with a very high risk of recurrence and indicates poor prognosis, whereas extrahepatic disease may be considered a contraindication for transplantation.
RESUMO
A choledochal cyst is a rare malformation primarily diagnosed in children. The only effective therapy remains surgical cyst resection followed by Roux-en-Y hepaticojejunostomy. Treating asymptomatic neonates remains a point of discussion. Between 1984 and 2021, we performed choledochal cyst (CC) excision in 256 children at our center. Out of this group, we retrospectively reviewed the medical records of 59 patients who were operated on under one year of age. Follow-up ranged from 0.3 to 18 years (median 3.9 years). The preoperative course was asymptomatic in 22 (38%), while 37 patients (62%) had symptoms before surgery. The late postoperative course was uneventful in 45 patients (76%). In symptomatic patients, 16% had late complications, while in asymptomatic patients, only 4%. Late complications were observed in the laparotomy group in seven patients (17%). We did not observe late complications in the laparoscopy group. Early surgical intervention is not followed by a high risk of complications and may prevent the onset of preoperative complications, giving excellent early and long-term results, especially after minimally invasive laparoscopic surgery.
RESUMO
INTRODUCTION: Perianal abscess and fistula-in-ano are common findings in infants and children. The perianal abscess is usually a manifestation of a fistula-in-ano. Experience of our center indicates general lack of knowledge of the origin of the abscess and therefore, it is usually treated by incision and drainage, which leads to repeated recurrences. AIM: We aimed to present the optimal management of fistula-in-ano and perianal abscess in order to reduce or even eliminate the risk of recurrence. MATERIAL AND METHODS: The retrospective study included 24 infants with perianal abscess treated at our center between 2013 and 2015. Patients were divided into two groups: group I (50%) was primary treated in our center, while group II had undergone prior surgical interventions in other hospitals. Fistula-in-ano was intraoperatively identified in all patients (100%) and fistulotomy was performed. RESULTS: No fecal incontinence or recurrence of perianal abscess were observed in any of our patients. In group II, the disorder was associated with severe inflammation, some patients underwent an additional surgical intervention, such as incision and drainage of an extensive buttock's abscess; patients required longer antibiotic therapy and prolonged hospitalization. CONCLUSION: Minimally invasive approach (sitz baths, antibiotic therapy, puncture or incision and drainage of the abscess) appears tempting due to its simplicity and lack of need for general anesthesia, but it is associated with a high recurrence rate. Fistulotomy and fistulectomy, which are slightly more invasive procedures, significantly reduce the recurrence rate of fistulain- ano and perianal abscess.
