Insights
Enhanced recovery programs can pose risks for patients undergoing VRAM flap perineal reconstruction. Early catheter removal may compromise flap viability, necessitating guideline revisions for improved patient safety and surgical outcomes.
Area of Science:
- Surgical reconstruction
- Enhanced recovery protocols
- Urology
Background:
- The enhanced recovery program (ERP) is a multimodal perioperative care strategy aimed at reducing surgical stress and length of hospital stay.
- The pedicled vertical rectus abdominis myocutaneous (VRAM) flap is a reconstructive technique used in perineal surgery.
- ERP was implemented in our institution in 2006 for colorectal surgical patients.
Observation:
- A patient undergoing perineal reconstruction with a VRAM flap developed bladder outflow obstruction.
- This obstruction compromised the viability of the VRAM flap.
- The complication occurred despite adherence to the enhanced recovery program.
Findings:
- Early catheter removal, a common component of ERP, can lead to bladder outflow obstruction in VRAM flap reconstructions.
- Bladder outflow obstruction poses a significant risk to flap viability in this patient population.
- Current ERP guidelines may not adequately address the specific needs of patients undergoing VRAM flap perineal reconstruction.
Implications:
- New guidelines are being developed to exempt patients undergoing VRAM flap reconstruction from certain ERP elements, specifically early catheter removal.
- Avoiding early catheter removal may prevent bladder outflow obstruction and preserve flap viability.
- These revised guidelines aim to enhance patient safety and optimize outcomes in complex perineal reconstructions.
Abstract:
The enhanced recovery programme, pioneered in the colorectal surgical setting, aims to reduce the length of inpatient stay following a procedure and was started in our trust in 2006. We present the case of a patient who underwent perineal reconstruction with a pedicled vertical rectus abdominis myocutaneous (VRAM) who subsequently developed bladder outflow obstruction compromising flap viability. As a result of our experience we are in the process of producing new guidelines that advocate patients undergoing a VRAM flap for perineal reconstruction should be exempt from aspects of the enhanced recovery programme, in particular early removal of the catheter should be avoided.
