Objective To investigate the effect of indenture appendicitis stent in endoscopic retrograde appendicitis (ERAT) and research its indenture time on reducing the recurrence of appendicitis after ERAT. Methods This study reviewed the clinical data of 94 patients accepted ERAT for suppurative appendicitis in Suining Central Hospital from September 2019 to December 2022. Patients were divided into stent group (n=42) and stentless group (n=52) according to whether or not they had indignant appendicitis during ERAT. The one-year recurrence rate, appendiceal stent retention time, abdominal pain VAS score, pain relief time, adverse events, length of hospital stay and total treatment cost were compared between the two groups. Results The recurrence rate in the stenting group was 4.7% lower than 19.2% in the stentless group (P=0.037). Of the 42 patients in the stent group, five had their stents come off automatically during follow-up, and the median stent retention time was 2.5 months. In stent group, the median stent retention time in patients with relapse was 0.84 months, which was less than 3 months in patients with no recurrence, and the difference was statistically significant (P=0.043).Conclusion In the treatment of suppurative appendicitis with ERAT, the retention of appendicitis stent and appropriate extension of the retention time can effectively prevent the recurrence of appendicitis
