Background Feed intolerance is a common problem in neonates with congenital duodenal obstruction (CDO). Some surgeons insert trans-anastomotic tubes (TAT) to facilitate feed tolerance. We conducted a systematic review to evaluate the efficacy and safety of TATs in CDO. Methods Medline, EmBase, CINAHL, and Cochrane Library were searched till July 2020. Risk of bias was assessed using ROBINS-I tool. Meta-analysis was conducted using Random Effects Model. Results No randomized controlled trials addressing the question were identified. In the 6 included observational studies, 96 infants underwent intraoperative TAT placement and 117 did not. Four studies reported benefits of TAT such as early attainment of full feeds and decreased need for parenteral nutrition. Two studies reported better outcomes in the no-TAT group. Accidental removal of TAT without clinical harm was reported in three studies [5/37 (14%), 4/17 (23%), and 2/4 (50%)]. Overall meta-analysis found no differences between the groups on any outcome. However, sensitivity analysis after excluding two studies with high risk of bias found that TAT tubes are associated with shorter duration of PN and shorter time to full enteral feeds. GRADE of evidence was very low for all outcomes. Conclusions Evidence is limited regarding the efficacy and safety of intraoperative TAT placement in neonates with CDO. Well-designed RCTs are needed to address the issue definitively.

Objective The aim of this study is to characterize long-term morbidities of oesophageal atresia (OA) with or without tracheoesophageal fistula (TOF). Methods Infants born with OA/TOF from 2000 to 2016 in Western Australia were included for analysis. Infants were categorized into high-risk and low-risk groups based on the presence of one or more perioperative risk factors [low birth weight, vertebraldefects, anal atresia, cardiac defects, TOF, renalanomalies, limb abnormalities (VACTERL), anastomotic leak, long gap OA, and failure to establish oral feeds within the first month] identified by a previous Canadian study. Frequency of morbidities in infants with perioperative risk factors was compared. Results Of 102 patients, 88 (86%) had OA with distal TOF (type C). The most common morbidities in our cohort were anastomotic oesophageal strictures (AS) (n=53, 52%), tracheomalacia (n=48, 47%), gastroesophageal reflux disease (GORD) (n=42, 41%) and recurrent respiratory tract infections (n=40, 39%). Presence of GORD (30/59 vs 12/43, p=0.04) and median frequency of AS dilatations (8 vs 3, n=59, p=0.03) were greater in the high-risk group. This study further confirmed that inability to be fed orally within the first month was associated with high morbidities. Conclusions Gastrointestinal and respiratory morbidities remain high in OA/TOF regardless of perioperative risk factors. Inability to be fed orally within the first month is a predictor of poor outcomes with high frequency of gastrointestinal and respiratory comorbidities.

Introduction: Pleuropulmonary blastoma (PPB) is a rare and aggressive primary neoplasm of pleuropulmonary mesenchyme occurring in children. The International PPB Registry was established in 1988 to collect and assess data on PPB worldwide. Objectives: The objectives of the study were to assess the clinical characteristics, histopathology, genetic studies, management, and treatment outcomes of patients with PPB in our institution, and to compare with the published literature. Materials and Methods: We retrospectively reviewed the medical records of all PPB cases diagnosed at Princess Margaret Hospital for Children in West Australia over a period of 26 years (1990–2016). Their clinical characteristics, histopathology, genetic studies, management, and treatment outcomes were recorded. Results: Seven children (four boys and three girls) were treated for PPB at a mean age of 11.5 months (ranges 1 month–3.55 years). Histopathology showed type I PPB in five, type II in one, and type III in one. All seven patients underwent thoracotomy/lobectomy of the corresponding site. One patient required additional bladder resection for coexisting rhabdomyosarcoma. One patient was found to be positive for DICER1 gene mutation. Six patients received adjuvant chemotherapy with vincristine, Adriamycin, and cyclophosphamide regime, with the mean duration of treatment for five patients being 9.4 months excluding one patient who deceased without completion of chemotherapy. During a mean follow-up time of 9 years, the overall survival rate for this cohort was 85.7% (6/7). Conclusion: Our results are comparable to those reported in the literature. It is crucial for clinicians to consider PPB in the evaluation of patients presenting with a cystic lung abnormality, especially in cases with DICER1 mutation or a strong family history of unusual cancers

Hepatopulmonary fusion (HPF) is an extremely rare finding in neonates who have a right diaphragmatic hernia. This case involves a neonate who had HPF with concurrent right lower lobe intra-lobar lung sequestration and coarctation of the aorta.The definitive diagnosis of HPF was made intra-operatively; however, there was a suspicion of HPF due to the presence of aright diaphragmatic hernia without mediastinal shift on the pre-operative imaging.

Introduction Pleuropulmonary blastoma (PPB) is an aggressive primary neoplasm of pleuropulmonary mesenchyme occurring in children. Given its rarity, the International Pleuropulmonary Blastoma Registry (IPPBR) was established in 1988 to collect and assess data on PPB worldwide. We assessed the clinical characteristics, histopathology, genetic studies, management, and treatment outcomes of patients with PPB in our institution, and compared with the published literature. Materials and Methods We retrospectively reviewed the medical records of all PPB cases diagnosed at Princess Margaret Hospital for Children in Western Australia over a period of 26 years (1990-2016). Results Seven children (4 boys and 3 girls) were treated for PPB at a mean age of 11.5 months (ranges 1 month to 3.55 years). Histopathology showed type I PPB in five, type II in one, and type III in one. All seven patients underwent thoracotomy/lobectomy of the corresponding site. One patient required additional bladder resection for coexisting rhabdomyosarcoma. One patient was found to be positive for DICER1 gene mutation. Six patients received adjuvant chemotherapy with vincristine, adriamycin, cyclophosphamide (VAC) regime, with the mean duration of treatment for five patients being 9.4 months excluding one patient who deceased without completion of chemotherapy. During a mean follow-up time of 9 years, the overall survival rate for this cohort was 85.7% (6/7). Conclusions Our results are similar to those reported in the literature. It is crucial for clinicians to consider PPB in the evaluation of patients presenting with a cystic lung abnormality, especially in cases with DICER1 mutation or a strong family history of unusual cancers.
