Endoscopic treatment for acute appendicitis with coexistent acute pancreatitis: Two case reports

Abstract

BACKGROUND Appendectomy is the procedure of choice for the treatment of acute appendicitis. However, surgery may not be appropriate for patients with coexisting severe illness or comorbidities such as acute pancreatitis (AP). Endoscopic retrograde appendicitis treatment (ERAT) may be a novel alternative to surgery for treating such patients where existing medical therapies have failed. CASE SUMMARY We report 2 cases of moderately severe AP who developed acute uncomplicated appendicitis during their hospital stay and did not respond to traditional medical therapy. One patient had moderately severe AP due to hyperlipidemia, while the other patient had a gallstone induced by moderately severe AP. Neither patient was fit to undergo an appendectomy procedure because of the concurrent AP. Therefore, the alternative and minimally invasive ERAT was considered. After written informed consent was collected from the patients, the ERAT procedure was performed. Both patients exhibited fast postoperative recovery after ERAT with minimal surgical trauma. CONCLUSION ERAT is a safe and effective minimally invasive endoscopic procedure for acute appendicitis in patients with coexistent AP.
