Surgical treatment of childhood hepatoblastoma in the Netherlands (1990–2013)

Background: Achievement of complete surgical resection plays a key role in the successful treatment of children with hepatoblastoma. The aim of this study is to assess the surgical outcomes after partial liver resections for hepatoblastoma, focusing on postoperative complications, resection margins, 30-day mortality, and long-term survival. Method: Chart reviews were carried out on all patients treated for hepatoblastoma in the Netherlands between 1990 and 2013. Results: A total of 103 patients were included, of whom 94 underwent surgery. Partial hepatectomy was performed in 76 patients and 18 patients received a liver transplant as a primary procedure. In 42 of 73 (58 %) patients, one or more complications were reported. In 3 patients, information regarding complications was not available. Hemorrhage necessitating blood transfusion occurred in 33 (45 %) patients and 9 (12 %) patients developed biliary complications, of whom 8 needed one or more additional surgical interventions. Overall, 5-year disease-specific survival was 82, 92 % in the group of patients who underwent partial hepatectomy, and 77 % in the group of patients who underwent liver transplantation. Conclusions: Partial hepatectomy after chemotherapy in children with hepatoblastoma offers good chances of survival. This type of major surgery is associated with a high rate of surgical complications (58 %), which is not detrimental to survival

A Solitary Intestinal Myofibroma: A Rare Cause of Neonatal Anemia

Solitary infantile myofibroma with visceral involvement is very rare. We present an unusual case of a solitary myofibroma with abdominal localization in a 1-day-old female neonate who presented with severe anemia and rectal bleeding. A bleeding myofibroma was found, located in the wall of the jejunum, and totally resected. In case of a solitary lesion, treatment is relatively easy and effective, with excellent prognosis after total resection. The multiple form (myofibromatosis) has a poor prognosis with low survival rates. We therefore recommend total body MRI for all patients diagnosed with myofibroma to rule out other lesions

The unique characteristics of intussusception after renal tumor surgery in children

Introduction: To further optimize survival rates as well as quality of cure for pediatric kidney tumors, attention for treatment related morbidity and mortality has become increasingly important. Intussusception is a rare but important complication after tumornephrectomy in children, causing morbidity, mortality and prolonged hospitalization. In this study, we describe two recent cases in our institute and provide a comprehensive review of the literature. Methods: For our narrative review, we searched for all reported cases of post tumor nephrectomy intussusception published until November 2016, using Pubmed and Embase libraries. Results: A total of 52 pediatric renal tumor cases who developed intussusception after tumor nephrectomy were identified. Median age was 23 months (range 3–84). Median time of onset was postoperative day 6 (range 1–18). Of 41 patients described in detail, only 4/41 were ileocolic, the others suffered from a small bowel intussusception. Most frequent presenting symptom was bilious vomiting. Preceding treatment approach was documented in 47 cases; i.e. preoperative chemotherapy had been administered to 10/47 patients. In 29 of 30 well documented cases, successful manually reduction during re-laparotomy was described and only 1 patient needed resection. All patients survived without recurrence of intussusception. Conclusion: In pediatric renal tumor patients, small bowel obstruction seems to reflect mostly post nephrectomy intussusception cases in contrast to the ileocolic idiopathic intussusceptions that are observed in healthy children. Symptoms of intussusception mimic chemotherapy related toxicity and general post-surgical symptoms, thereby initiating a significant delay in diagnosis. Awareness of intussusception after renal tumor surgery is warranted
