Appendicitis in Neutropenic Pediatric Oncology Patients: A Case Series and Review of the Literature

A scoping review on acute gastrointestinal surgical complications in immunocompromised pediatric patients

Background

Gastrointestinal complications are becoming increasingly more common and pose a significant risk on the health of children with compromised immunity caused by various etiologies such as chemotherapy and posttransplantation immunosuppression. We aim to review abdominal complications in immunocompromised children and their respective management.

Main body

This is a scoping review of the literature. PubMed, MEDLINE, Google Scholar, and Scopus libraries were searched for relevant articles. Extracted data included the etiologies of immunocompromised immunity, gastrointestinal and abdominal complications in immunocompromised children, diagnosis, and treatment of these pathologies. Examples of gastrointestinal complications in immunocompromised children include, but not limited to, neutropenic enterocolitis, acute appendicitis, bowel perforation, acalculous cholecystitis, and acute pancreatitis. Our literature review showed that bacterial and fungal infections are the major causes of exacerbation and mortality. The main cause of immunosuppression in children with neutropenic enterocolitis and acute pancreatitis is chemotherapy, and management of these pathologies using intravenous fluids, antibiotic therapy, and granulocyte-stimulating factors is the current standard of care. Surgical intervention is uncommon and reserved for complicated cases. That said, in acute appendicitis and bowel perforation, laparoscopy is the mainstay treatment. However, in systemic infections, nonsurgical interventions such as transfusion and bowel rest are the gold standard. As for acalculous cholecystitis, percutaneous cholecystectomy is superior to laparotomy and other surgical interventions.

Conclusion

Timely diagnosis and management of gastrointestinal complications in the immunocompromised children is key in reducing mortality and morbidity. Both surgical and nonsurgical interventions are needed and should be further studied in order to improve outcomes.

Appendectomy in pediatric patients with synchronous oncologic diagnosis is safe: an analysis using the national surgical quality improvement project, pediatric

BACKGROUND

Optimal treatment of children who develop appendicitis while undergoing treatment for an oncologic diagnosis has not been defined, in part due to theoretical concerns for an increased risk of postoperative wound complications. We hypothesized that synchronous oncologic diagnosis conferred no increased odds of developing a wound complication in pediatric patients undergoing appendectomy.

METHODS

Retrospective cohort study using the National Surgical Quality Improvement Program, Pediatric (2012-2017) of patients < 18 years of age undergoing appendectomy. The main exposure variable was active treatment for an oncologic diagnosis. The primary outcomes of interest were 30-day wound complications (superficial or deep infections or dehiscence, and abscess). For univariate analysis comparison of baseline differences between patients with/without a cancer diagnosis we employed Pearson's χ² and two sample t tests. Multivariate logistic regression was used to evaluate which covariates were independently associated with our outcome.

RESULTS

We identified 28,219 patients who had undergone appendectomy; 95 (0.3%) were undergoing oncologic treatment at the time of surgery. Patients in the cancer group were more likely to be receiving steroids, have lower white blood cell counts and have higher American Society of Anesthesiology classes as compared to the noncancer patients. Age, gender, rates of perforation, and laparoscopy were similar between the two groups. Patients with an active cancer diagnosis suffered wound complications (measured individually and as an aggregate) at no higher odds than those without a cancer diagnosis.

CONCLUSION

Pediatric patients undergoing treatment for cancer do not have increased odds of suffering postoperative wound complications following appendectomy as compared to the general population.
