Abstract

Background

Endoscopic retrograde appendicitis therapy (ERAT) is a new method of treating acute appendicitis that has emerged in recent years in children, but the application of radiological examination in the diagnosis and treatment of pediatric diseases is greatly limited. Therefore, high-frequency ultrasonography imaging has attracted more and more attention because of its advantages such as non-invasiveness, no radiation, and a simpler procedure. This study aims to explore the application value of high-frequency ultrasonography in ERAT for pediatric acute appendicitis.

Methods

A retrospective analysis was conducted on 136 children admitted to our hospital from January 2020 to October 2021 who were definitively diagnosed with acute appendicitis and underwent endoscopic retrograde intra-appendiceal irrigation treatment under the guidance of high-frequency ultrasonography. They were divided into the preschool age group (< 6 years) and school age group (≥ 6 years) according to age. Before the operation and at 1–2 days after ERAT, the external diameter of the appendix, as well as the thickness of the intestinal wall, mucosal layer, and muscular layer in each group were measured by high-frequency ultrasonography and recorded in detail. During the operation, a stent was placed under real-time guidance, and the situation in the cavity was observed. The clinical data of the two groups of children before and after the operation were collected, and the recurrence status after treatment was followed up.

Results

Endoscopic treatment was completed in 131 patients with a success rate of 96.32%. There was no significant difference between the two groups in appendix diameter, intestinal wall, or muscular layer after the operation when compared to those before the operation (p > 0.05), but there was a significant difference in the mucosal thickness after operation when compared to before the operation (p < 0.05). Abdominal pain in the two groups was significantly relieved immediately after the operation, and the white blood cell count returned to normal, with a significant difference before and after the ERAT operation (p < 0.05).

Conclusion

Endoscopic intra-appendiceal irrigation under the guidance of high-frequency ultrasonography is a real-time and convenient method that is safe and effective in treating pediatric acute appendicitis.
