Iatrogenic diaphragmatic herniation of the liver into the pericardium-a case report.

Iatrogenic diaphragmatic herniation is rare. This case is an example of herniation of the liver into the pericardial space post-transdiaphragmatic pericardial window formation for recurrent pericarditis. This case highlights that transdiaphragmatic herniation of intra-abdominal organs should be considered in patients presenting with gastrointestinal or cardiorespiratory symptoms with history of iatrogenic diaphragmatic defect.

Prevalence, management and efficacy of treatment in portal vein obstruction after paediatric liver transplantation: protocol of the retrospective international multicentre PORTAL registry.

INTRODUCTION: Portal vein obstruction (PVO) consists of anastomotic stenosis and thrombosis, which occurs due to a progression of the former. The aim of this large-scale international study is to assess the prevalence, current management practices and efficacy of treatment in patients with PVO. METHODS AND ANALYSIS: The Portal vein Obstruction Revascularisation Therapy After Liver transplantation registry will facilitate an international, retrospective, multicentre, observational study, with 25 centres around the world already actively involved. Paediatric patients (aged <18 years) with a diagnosed PVO between 1 January 2001 and 1 January 2021 after liver transplantation will be eligible for inclusion. The primary endpoints are the prevalence of PVO, primary and secondary patency after PVO intervention and current management practices. Secondary endpoints are patient and graft survival, severe complications of PVO and technical success of revascularisation techniques. ETHICS AND DISSEMINATION: Medical Ethics Review Board of the University Medical Center Groningen has approved the study (METc 2021/072). The results of this study will be disseminated via peer-reviewed publications and scientific presentations at national and international conferences. TRIAL REGISTRATION NUMBER: Netherlands Trial Register (NL9261).

Perioperative Blood Transfusions and Anastomotic Leak After Colorectal Surgery for Cancer in an Australian Hospital.

PURPOSE: Peri-operative blood transfusion has been identified as a risk factor for anastomotic leak in recent studies, but little is known about which patients are at risk for blood transfusion. This study aims to assess the relationship between blood transfusion and anastomotic leak and factors predisposing to leak in patients undergoing colorectal cancer surgery. METHODS: This retrospective cohort study was conducted in a tertiary hospital in Brisbane, Australia, between 2010 and 2019. A total of 522 patients underwent resection of colorectal cancer with primary anastomosis with no covering stoma and the prevalence of anastomotic leak was compared between those who had had perioperative blood transfusion(s) and those who had not. RESULTS: A total of 19 of 522 patients undergoing surgery for colorectal cancer had developed an anastomotic leak (3.64%). 11.3% of patients who had had a perioperative blood transfusion developed an anastomotic leak whereas 2.2% of patients who had not had a blood transfusion developed an anastomotic leak (p = 0.0002). Patients undergoing procedure on their right colon had proportionally more blood transfusions and this approached statistical significance (p = 0.06). Patients who received a greater quantity of units of blood transfusion prior to their diagnosis of anastomotic leak were more likely to develop an anastomotic leak (p = 0.001). CONCLUSION: Perioperative blood transfusions are associated with a significantly increased risk of an anastomotic leak following bowel resection with primary anastomosis for colorectal cancer.

The effectiveness and safety of antibody induction immunosuppression in a large cohort of United States pediatric liver transplant recipients.

Data on the potential benefits and risks of induction therapy in pediatric liver transplantation (LT) are limited. This was a retrospective cohort study of 2748 pediatric LT recipients at 26 children's hospitals between January 1, 2006 to May 31, 2017 using data from the pediatric health information system linked to the United Network for Organ Sharing database. The induction regimen was obtained from the pediatric health information system day-by-day pharmacy resource utilization. Cox proportional hazards evaluated the association of induction regimen (none/corticosteroid-only, nondepleting, and depleting) on patient and graft survival. Additional outcomes, including opportunistic infections and posttransplant lymphoproliferative disorder, were studied using multivariable logistic regression. Overall, 64.9% received none/corticosteroid-only induction, whereas 28.1% received nondepleting, 8.3% received depleting, and 2.5% other antibody regimens. Differences in patient characteristics were small, but center practices were heterogeneous. Compared with none/corticosteroid-only induction, nondepleting induction was associated with reduced acute rejection (odd ratio [OR], 0.53; P <.001) but with the increased posttransplant lymphoproliferative disorder (OR, 1.75; P =.021). Depleting induction was associated with improved graft survival (hazard ratio [HR], 0.64; P =.028) but with increased noncytomegalovirus opportunistic infections (OR, 1.46; P =.046). Depleting induction is underused yet may offer long-term benefits in this large multicenter cohort. Greater consensus guidance in this aspect of pediatric LT care is warranted.

Management of Magnet Ingestions at a Large Tertiary Care Children's Hospital.

OBJECTIVES: To review the clinical management and outcomes of magnet ingestions at a large tertiary children's hospital. To determine the association of frequency of high-powered magnet ingestion with the regulation of these magnets. METHODS: Children <18 years who presented to the emergency room and were admitted to the Children's Hospital of Philadelphia for ingestion of single or multiple magnets from January 2008 to December 2020 were included. Demographics, symptoms, management, and outcomes were analyzed. The frequency of magnet ingestion was compared over 3 eras: (1) pre-ban (2008-2012), (2) intra-ban (2013-2016), and (3) post-ban (2017-2020). RESULTS: There were 167 magnet ingestions, including 99 with multiple magnets. Most patients (59%) were male and median age was 6 (interquartile range, 3-9) years. Most single magnet ingestions (86%) were discharged with outpatient monitoring, and none experienced severe outcomes. Multiple magnet ingestions led to significant morbidity including hospitalizations (68%), endoscopic procedures (48%), surgical procedures (14%), and severe outcomes (12%). Most patients (75%) were asymptomatic, however, there was a higher risk of surgery and severe complications based on the presence of symptoms ( P = 0.003). The rate of surgical intervention was higher with ≥3 magnets (31.7%) compared to 2 magnets (2.4%) ( P < 0.003). Additionally, we found an 160% increase in children with magnet ingestions in the post-ban period ( P = 0.021). CONCLUSIONS: Multiple magnet ingestion is associated with high morbidity and rate of severe outcomes. There is a relationship between public policy of magnet sale and frequency of magnet ingestion.
