Laparoscopic pelvic mesh placement with closure of pelvic floor entrance to prevent small intestine radiation trauma - A retrospective cohort analysis

Background: In most pelvic malignancies radiation therapy is a main part of the treatment concept. The main dose limiting organ is the small intestine. Different mechanical methods to prevent radiation damage to the small intestine have been described. We herein report a retrospective study of laparoscopic placement of an absorbable vicryl mesh in patients requiring pelvic radiotherapy displacing the bowel out of the radiation field.

Patients/methods: The study included 6 consecutive patients requiring definitive radiotherapy due to locally advanced prostate cancer. All patients had small intestine within the radiation fields despite the use of non-invasive displacement methods.

Results: All patients underwent laparoscopic small bowel displacement from the pelvis and closure of the pelvic floor entrance using vicryl mesh placement. Peri- or postoperative complications were not seen. Postoperative radiotherapy planning CT scans confirmed displacement of the small intestine allowing all patients to receive the planned radiotherapy volume.

Conclusion: Laparoscopic mesh placement represents a safe and efficient procedure in patients requiring high-dose pelvic radiation, presenting with unacceptable small intestine volume in the radiation field. As an alternate to native tissue, the vicryl mesh is a safe, effective substitute for small bowel exclusion from external-beam radiation therapy.
