Abstract:

Objective

To analyze the complications of temporary abdominal aortic balloon occlusion in pelvic tumor resection surgery and the risk factors affecting the occurrence of severe complications.

Methods

Pelvic tumor patients who underwent surgery at the Department of Retroperitoneal Tumor Surgery, Peking University International Hospital from January 2014 to June 2024 were collected.All the patients used the temporary abdominal aortic occlusion balloon during the operation. According to the severity of postoperative complications (based on the Clavien-Dindo classification), the patients were divided into a severe complication group (complications≥grade 3) and a non-severe complication group (no complications or complications≤grade 2). The occurrence of postoperative complications in all patients was statistically analyzed, and by comparing the differences in clinical and pathological data between the two groups, the possible risk factors related to the occurrence of severe complications were explored.

Results

A total of 25 patients were included, of which 21 achieved R0/R1 resection. A total of 6 patients experienced severe complications (≥grade 3) (24%), all of whom recovered and were discharged after treatment, with no perioperative deaths. There were no significant differences between patients with severe complications and those without in terms of gender, age, tumor status, combined organ resection, intraoperative bleeding and transfusion volume, operation time, number of occlusions, or postoperative hospital stay (P>0.05). The cumulative occlusion time (P=0.001) and the longest single occlusion time (P=0.032) were longer in the group with severe complications.

Conclusion

Prolonged occlusion time and longer single occlusion time may be risk factors for severe complications after the use of temporary abdominal aortic occlusion balloon in pelvic tumor resection surgery. By reducing intraoperative occlusion time, it is possible to reduce the occurrence of severe postoperative complications while minimizing bleeding.
