Abstract:To investigate the efficacy and prognosis of appendiceal stent placement under direct vision using a digital cholangiopancreatic endoscope system for acute appendicitis, a retrospective cohort study was conducted. Relevant data of patients with acute appendicitis who received endoscopic retrograde appendicitis therapy (ERAT) at Huai''an Second People''s Hospital from January 2022 to October 2024 were collected. The patients were divided into non‑stenosis group and stenosis group according to the presence or absence of stenosis in the appendiceal lumen. Then, they were further divided into the stent group and the non‑stent group according to the placement of appendiceal stent during the ERAT procedure. The clinical symptoms, surgery‑related indicators, and prognosis improvement of patients with acute appendicitis were analyzed. A total of 116 patients'' data were collected. Among the patients in the non‑stenosis group, 25 cases received stent placement and 37 cases did not. There were no statistically significant differences in clinical symptoms, surgery‑related indicators, or prognosis between the two groups (P0.05). Among the patients in the stenosis group, 31 cases received stent placement and 23 cases did not. The pain level at 2 hours after the operation in the stent group was lower than that in the non‑stent group [1.00 (0.00, 3.00) points VS 3.00 (1.00, 3.00) points, Z=-2.452, P=0.014]. The duration of abdominal pain after the operation in the stent group was shorter than that in the non‑stent group [3.00 (0.00, 5.00) hours VS 5.00 (3.00, 10.00) hours, Z=-2.756, P=0.006]. The intraoperative blood loss in the stent group was less than that in the non‑stent group [2.00 (1.00, 3.00) mL VS 4.00 (2.00, 5.00) mL, Z=-2.426, P=0.019]. After a 6‑month follow‑up, the recurrence rate in the stent group was lower than that in the non‑stent group [3.23% (1/31) VS 26.09% (6/23), χ2=6.116, P=0.039]. The implantation of appendiceal stent can improve the condition and prognosis of patients with acute appendicitis accompanied by stenosis.
