Transcatheter Arterial Embolization in the Treatment of Abdominal Bleeding in Patients Being Treated with Open Abdomen Due to Duodenal Fistula

摘要

Background This study aimed to investigate the transcatheter arterial embolization (TAE) in treatment of abdominal bleeding in patients being treated with open abdomen due to duodenal fistula. Methods This was a retrospective study performed at our center. From January 2005 to November 2010, all patients with abdominal bleeding were treated with surgical hemostasis (SH) and included in SH group. From January 2012 to December 2018, all patients with a bleeding were treated with TAE and included in the TAE group. Clinical data were reviewed and compared between the two groups. The effect of TAE in the management of abdominal bleeding was evaluated. Results A total of 131 patients were enrolled, and there were 64 in the SH group and 67 in the TAE group. The success rate of hemostasis was higher in the TAE group (89.55% vs. 73.44%, adjusted OR = 4.065, 95% CI 1.336-12.336,P = 0.013). Moreover, the recognition rate of hemorrhagic vessels in the TAE group was higher (91.04 vs. 51.56;P < 0.001). The re-bleeding occurred in 20 patients, 7(11.67%) in the TAE group and 13(27.66%) in the SH group. The re-bleeding rate in SH group was higher (adjusted HR = 2.564, 95% CI 1.023-6.428,P = 0.045) Conclusions TAE is an effective method in treatment of abdominal bleeding in patients being treated with open abdomen due to duodenal fistula.
