Insights

Pediatric intestinal failure, often from surgical issues or motility disorders, may necessitate intestine transplantation. Centers of excellence report high survival rates, with research focused on reducing chronic rejection.

Area of Science:

  • Pediatric surgery
  • Gastroenterology
  • Transplantation immunology

Background:

  • Pediatric intestinal failure stems from surgical conditions (e.g., necrotizing enterocolitis, gastroschisis) or functional disorders (e.g., intestinal pseudo-obstruction, microvillus inclusion disease).
  • Intestine replacement becomes necessary for severe cases impacting growth and quality of life.

Purpose of the Study:

  • To outline the indications, surgical approaches, immunosuppression protocols, and outcomes of intestinal transplantation in children.
  • To highlight the current survival rates and future research directions in pediatric intestinal transplantation.

Main Methods:

  • Review of indications for intestinal transplantation, including liver dysfunction, central line complications, and severe dehydration.
  • Description of surgical techniques: isolated intestine, combined liver-intestine, and multivisceral transplantation.
  • Summary of immunosuppression regimens, primarily tacrolimus-based with induction therapy.

Main Results:

  • Centers of excellence report 1-year patient survival rates of 95% and 5-year survival rates of 77%.
  • Key indications include liver dysfunction, loss of venous access, and recurrent sepsis or dehydration.

Conclusions:

  • Intestinal transplantation is a viable option for children with irreversible intestinal failure, offering significant survival benefits.
  • Ongoing research aims to mitigate long-term graft loss, particularly from chronic rejection, to further improve patient outcomes.

Kidney Transplant I: Introduction01:28

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
