Abstract:Objective To investigate the diagnostic and therapeutic value of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis therapy in the treatment of acute uncomplicated appendicitis.Methods A retrospective analysis was conducted on the clinical data of 39 patients with acute uncomplicated appendicitis who underwent single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment at the Endoscopy center of the hospital from September 2022 to September 2024. Observe the endoscopic manifestations, the rate of maternal and child basket stone removal, the rate of appendiceal stent implantation, the technical success rate, the clinical success rate, the operation time, the hospital stay, the incidence of complications, the visual analogue scale (VAS) score 6 hours after the operation, and the inflammatory indicators 24 hours after the operation.Results In 28 cases (71.8%), congestion and edema could be seen at the opening of the appendix under colonoscopy. In 10 cases (25.6%), pus could be seen flowing out of the opening of the appendix under colonoscopy. In 32 cases (82.1%), a large amount of pus could be seen in the lumen of the appendix under subscopy. In 20 cases (51.3%), appendiceal fecalith could be seen in the lumen of the appendix under subscopy. The technical success rate of single-use mother-baby choledochoscope-assisted endoscopic retrograde appendicitis treatment was 100.0% (39/39). The operation time was (21.08 ± 7.49) min; Hospital stay: (3.97 ± 2.08) days; Eight cases (20.5%) of patients underwent endoscopic maternal basket stone removal. Appendiceal stent implantation was performed in 14 cases (35.9%) of patients. The clinical success rate is 97.4% (38/39). One patient's clinical symptoms and inflammatory indicators did not improve after the operation, and was transferred to the surgery department for appendectomy. The VAS score of 38 patients was less than 3 points 6 hours after the operation, and the abdominal pain symptoms were significantly relieved. The white blood cell count and the percentage of neutrophils 24 hours after the operation decreased significantly compared with those before the operation, and the differences were statistically significant (P < 0.05). None of the 39 patients had complications. The postoperative follow-up was (5.94 ± 4.03) months, and recurrence occurred in 3 cases (7.7%).Conclusion single-use mother-baby choledocoscope-assisted endoscopic retrograde appendicitis therapy is safe and effective in the diagnosis and treatment of acute uncomplicated appendicitis, which is worthy of further promotion and popularization in clinical practice.
