# Beyond the scope: endoscopic ultrasound—assisted appendicoscopy by use of a single-use cholangioscope for endoscopic appendicitis therapy: a case report

## TL;DR

A new minimally invasive technique using endoscopic ultrasound and a cholangioscope successfully treated appendicitis in a patient.

## Contribution

This case report introduces EUS-assisted appendicoscopy using a single-use cholangioscope for endoscopic appendicitis therapy.

## Key findings

- EUS-assisted EAT enabled successful cholangioscope intubation and treatment of appendicitis.
- The patient experienced rapid recovery and remained asymptomatic at 3-month follow-up.
- The technique improves access and precision in endoscopic appendicitis management.

## Abstract

Endoscopic appendicitis therapy (EAT) is an emerging minimally invasive alternative to surgery. This case highlights using endoscopic ultrasound (EUS) to facilitate cholangioscope-guided appendicoscopy. A 41-year-old woman presented with acute right lower quadrant pain and leukocytosis. Computed tomography confirmed acute appendicitis. The patient opted for EAT. EUS identified appendiceal orientation, enabling smooth cholangioscope intubation via colonoscope. Irrigation cleared purulent discharge. Following rapid recovery, the patient remained asymptomatic at 3-month follow-up. EUS-assisted EAT improves access, precision, and efficiency in endoscopic management of appendicitis. This technique may broaden the role of minimally invasive, organ-preserving approaches as an alternative to surgery in selected patients.
