Seprafilm and adhesive small bowel obstruction in colorectal/abdominal surgery: an updated systematic review.

BACKGROUND

The efficacy of Seprafilm in preventing clinically significant adhesive small bowel obstruction (ASBO) is controversial and deserves further review. The aim of this review was to assess the utility of Seprafilm in preventing clinically significant adhesive bowel obstruction after abdominal operations, with separate focus on colorectal resections. The secondary aim was to provide an updated literature review on the safety profile of this implant.

METHODS

An up-to-date systematic review was performed on the available literature between 2000 and 2023 on PubMed, EMBASE, Medline, and Cochrane Library databases. The main outcome measures were rates of adhesive bowel obstruction, as well as rates of intervention. The secondary outcome was the clinical safety profile of Seprafilm as described in current literature.

RESULTS

A total of 17 observational studies were included, accounting for 62,886 patients. Use of Seprafilm was associated with a significant reduction in adhesive bowel obstruction events (OR 0.449, 95% CI: 0.3271 to 0.6122, p < 0.001), with preserved efficacy seen in laparoscopic cases. This did not translate into a reduced rate of reintervention. Clinicians should also be aware of isolated reports of a paradoxical inflammatory reaction leading to fluid collections after Seprafilm use, although they appear uncommon.

CONCLUSION

Seprafilm can be considered in select patients although further study to determine which patients will benefit most is required.
