Stereotactic body radiotherapy as a rescue modality for definitive treatment of therapy-refractory fistulas after pancreatic surgery
Clinical Scorecard: Utilization of MR-guided Stereotactic Body Radiotherapy as a Salvage Treatment for Persistent Postoperative Pancreatic Fistulas Following Surgical Intervention
MR-guided stereotactic body radiotherapy (SBRT) to reduce fistula output and promote closure
Target Population
Patients with persistent, severe postoperative pancreatic fistulas unresponsive to conventional treatments
Care Setting
Postoperative management in specialized centers with access to MR-guided SBRT
Key Highlights
SBRT led to permanent drain removal in all five treated patients with refractory POPF.
Rehospitalizations due to fistula-related complications dropped to zero after SBRT.
No significant gastrointestinal toxicity observed; only mild fatigue reported in one patient.
Guideline-Based Recommendations
Diagnosis
Use ISGPS 2016 criteria to grade postoperative pancreatic fistulas (Grade B/C).
Identify refractory POPF by persistent high-output fistulas and severe complications despite standard care.
Management
Consider MR-guided SBRT as a salvage, non-invasive treatment option for refractory POPF after failure of conventional therapies.
Administer SBRT in 5 fractions of 4–8 Gy each under MR guidance.
Monitoring & Follow-up
Monitor drain output to assess treatment response, aiming for significant reduction and eventual removal.
Track rehospitalization rates and complications such as abscesses or drain malfunctions post-SBRT.
Risks
SBRT demonstrated minimal toxicity with no relevant gastrointestinal adverse effects in the reported series.
Potential mild fatigue may occur; long-term risks require further study.
Patient & Prescribing Data
Five male patients post pancreatic surgery (proximal, distal resection, or necrosectomy) with refractory Grade B/C POPF.
SBRT effectively reduced median drain output from 47.5 ml/day to 2 ml/day, enabling drain removal after a median of 44 days and eliminating rehospitalizations.
Clinical Best Practices
Integrate MR-guided SBRT into multidisciplinary management algorithms for refractory POPF.
Use SBRT as a salvage therapy when standard surgical and medical treatments fail.
Conduct prospective studies to validate efficacy and safety in larger patient cohorts.
