Abstract:
Objective:To evaluate the efficacy and safety of modified mushroom-shaped occluder in the treatment of refractory thoracogastric-airway fistulas.Methods:From March 1, 2022 to June 30, 2023, 12 patients with refractory thoracogastric-airway fistulas underwent the placement of modified mushroom-shaped occluder at the Department of Gastroenterology, the First Affiliated Hospital of Nanjing Medical University were enrolled. The baseline clinical data of patients such as gender, age, course of disease, and fistula diameter were recorded. The data of operation and follow-up, such as operation time and method, intraoperative and postoperative complications were also collected. The occlusion efficacy at 1 month and 6 months after surgery, as well as the improvement of body mass index (BMI) and scores of the short form 36 (SF-36) were analyzed. Paired t test and non-parametric test were used for statistical analysis. Results:There were 10 males and 2 females among the 12 patients. The median age was 66.5 years old (ranged from 53.0 to 69.0 years old), the median course of disease was 7.5 months (ranged from 3.0 to 39.0 months), and the diameter of fistula was (9.3±3.4) mm. The occluder placements were successful in all the 12 patients, with 6 cases intracavitary release and 6 extracavitary release. The operation time was (30.9±9.9) min and the time of occluder placement was (3.5±1.3) min. One patient had minor (<2 mL) bleeding during the operation and 2 patients reported mild foreign body sensation but tolerable after operation. All patients resumed oral feeding and nasojejunal tubes were removed before discharge. The follow-up time of 12 patients was (11.3±1.7) months. The initial effective occlusion rate was 11/12, and the complete occlusion rate was 9/12. Two patients died but neither were related to the procedure or instruments. The BMI of 12 patients at 1 month after surgery was (18.5±1.9) kg/m 2, which was higher than that before operation ((17.6±2.3) kg/m 2), the BMI at 6 months after operation was (20.3±2.5) kg/m 2, which was higher than that at 1 month after operation, and the differences were statistically significant ( t=-4.15 and -4.45, P=0.002 and 0.001). The scores of 8 domains of SF-36 including physical functioning, general health, vitality, mental health, role-physical, bodily pain, social functioning and role-emotional of 12 patients before operation, at 1 month after operation and 6 months after operation were 49.6±13.6, 63.3±13.5 and 75.4±8.6, 17.1±11.2, 33.2±14.5 and 56.0±12.2, 30.0±12.6, 45.0±13.5 and 67.5±8.7, 41.3±18.7, 52.0±15.4 and 68.0±8.2, 0.0 (0.0 to 75.0), 25.0 (0.0 to 100.0) and 50.0 (25.0 to 100.0), 87.8 (44.0 to 100.0), 90.8 (57.0 to 100.0) and 100.0 (94.0 to 100.0), 12.5 (0.0 to 50.0), 50.0 (37.5 to 75.0) and 81.3 (50.0 to 87.5), 0.0 (0.0 to 100.0), 66.7 (33.3 to 100.0) and 100.0 (33.3 to 100.0), respectively. The scores of 8 domains at 1 month after operation were all higher than those before operation, and the differences were statistically significant ( t=-5.25, -5.32, -4.87 and -2.51, Z=-2.97, -2.20, -3.11 and -3.00; all P<0.05). The scores of 8 domains at 6 months after operation were all higher than those at 1 month after operation, and the differences were statistically significant ( t=-4.34, -7.48, -7.10 and -4.64, Z=-2.49, -2.20, -2.97 and -2.07; all P<0.05). Conclusion:The clinical application of the improved mushroom-shaped occluder in the treatment of refractory thoracogastric-airway fistulas is effective and relatively safe.
