Transumbilical laparoscopic-assisted appendectomy without pneumoperitoneum in children: Feasibility and outcomes from a single center

jpedsurg.org

Transumbilical laparoscopic-assisted appendectomy (TULAA) is a minimally invasive technique for pediatric acute appendicitis. While most TULAA procedures utilize pneumoperitoneum, we adopted a modified technique involving mechanical elevation of the abdominal wall without insufflation. This study aimed to evaluate the safety and efficacy of TULAA without pneumoperitoneum by analyzing clinical outcomes in pediatric patients who underwent this procedure at our institution.

In brief

This study examines a modified transumbilical laparoscopic appendectomy technique for children with acute appendicitis that uses mechanical abdominal wall elevation instead of gas insufflation. The single-center analysis evaluates whether this gasless approach maintains safety and effectiveness compared to traditional pneumoperitoneum-based TULAA procedures.

TULAA can be safely performed without pneumoperitoneum using mechanical abdominal wall elevation in pediatric appendicitis cases.
This modified technique eliminates CO2 insufflation risks while maintaining minimally invasive benefits in children.
Single-center outcomes demonstrate feasibility of pneumoperitoneum-free TULAA as an alternative approach to traditional laparoscopy.
