Small bowel obstruction after FloSeal use

Objective:
FloSeal is a thrombin-gelatin hemostatic matrix that is used to obtain hemostasis. There have been isolated case reports of FloSeal causing bowel obstructions, requiring surgical intervention. We report 3 cases of what we believe were FloSeal-induced small bowel obstructions (SBO).
Methods:
We present a series of small bowel obstructions after FloSeal use. Our series includes urology, gynecologic oncology, and general surgery cases at the same institution where the product was appropriately used and resulted in the same complication.
Results:
FloSeal was used for hemostasis in all patients. In each instance, a small bowel obstruction developed in 7 days to 9 days. All patients were reexplored laparoscopically and found to have an intense inflammatory reaction at the site of the FloSeal. The adhesions were lysed and the obstructions resolved.
Conclusions:
Although further study is needed, the common factor in all these SBOs was a hemostatic agent. In our and others' series, the time to SBO was 7 days to 9 days. If an early postoperative SBO occurs after FloSeal is used, prompt reexploration should be considered.
Insights
FloSeal (thrombin-gelatin hemostatic matrix) may cause small bowel obstructions (SBO) 7-9 days post-surgery. Prompt reexploration is recommended for early postoperative SBO after FloSeal use.
Area of Science:
- Surgical complications
- Gastroenterology
- Medical device safety
Background:
- FloSeal is a widely used hemostatic matrix for achieving hemostasis during surgical procedures.
- Previous isolated case reports have suggested a potential link between FloSeal use and bowel obstructions.
Observation:
- This series presents three cases of small bowel obstruction (SBO) following the appropriate use of FloSeal across various surgical specialties.
- The patients developed SBOs between 7 and 9 days postoperatively.
Findings:
- Laparoscopic reexploration revealed intense inflammatory reactions and adhesions at the sites where FloSeal was applied.
- Surgical lysis of adhesions successfully resolved the obstructions in all reported cases.
Implications:
- The findings suggest a potential causal relationship between FloSeal and the development of early postoperative SBOs.
- Prompt surgical reexploration should be considered in patients presenting with SBO after FloSeal application.
- Further investigation into the inflammatory properties of hemostatic agents like FloSeal is warranted.
