Transumbilical Laparoscopic-Assisted Appendectomy in the Treatment of Acute Uncomplicated Appendicitis in Children

Abstract EN

Transumbilical laparoscopic-assisted appendectomy (TULAA) is increasingly being performed worldwide.

The authors report their experience in the treatment of acute uncomplicated appendicitis in children with TULAA.

From January 2008 to December 2012 all types of acute appendicitis were divided, according to the clinical and ultrasonographic findings, into complicated (appendiceal mass/abscess, diffuse peritonitis) and uncomplicated.

Complicated appendicitis was treated by open appendectomy (OA).

All patients with the suspicion of uncomplicated appendicitis were offered TULAA by all surgeons of the team.

Conversion to open or laparoscopic appendectomy (LA) was performed in case of impossibility to complete TULAA, depending on the choice of surgeon.

The histopathologic examination of appendix was always performed.

444 children (252 males) with acute appendicitis were treated.

The mean age was 9.2 years (range, 2 to 14 years).

Primary OA was performed in 144 cases.

In 300 patients a transumbilical laparoscopic-assisted approach was performed.

TULAA was completed in 252 patients.

Conversion to OA was performed in 45 patients and to LA in 3.

Conversion was related to the impossibility to adequately expose the appendix in 47 patients and bleeding in 1.

The mean operative time for TULAA was 42 minutes.

Histopathologic examination of the appendix removed by TULAA showed a phlegmonous/gangrenous type in 92.8% of cases.

Among the 252 TULAA there were 11 cases of umbilical wound infection.

TULAA is a feasible and effective procedure for uncomplicated appendicitis in children.

It combines the advantages of open and laparoscopic technique (low operative time, low complications rate, and excellent cosmetic results).
