Formalin instillation effectively treats hemorrhagic radiation proctitis. Both sponge stick and irrigation methods show success, with sponge stick application achieving higher initial hemostasis rates for radiation-induced rectal bleeding.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Radiation Oncology

Background:

  • Hemorrhagic radiation proctitis is a common complication of pelvic radiotherapy.
  • Formalin instillation is a recognized treatment, but technique variations exist.
  • Different instillation methods may impact efficacy and patient outcomes.

Purpose of the Study:

  • To evaluate the effectiveness of formalin instillation for radiation proctitis.
  • To compare outcomes between two distinct formalin instillation techniques: sponge stick (SS) and irrigation (IR).

Main Methods:

  • A prospective database identified 21 patients treated with 4% formalin for radiation proctitis.
  • Two techniques were compared: SS (sponge stick application, 2.5 min contact) and IR (aliquot irrigation, 30 sec contact).

  • Patient demographics, treatment details, procedural outcomes, and complications were analyzed.

    • Main Results:

    • The SS group (17 patients) showed a higher initial hemostasis rate (82.4%) compared to the IR group (75%).
    • Repeat instillation was required in 5.9% of SS patients and 25% of IR patients.
    • Adverse events included rectal pain and fecal incontinence in the SS group, and colitis in the IR group.

    Conclusions:

    • Formalin instillation is an effective treatment for refractory hemorrhagic radiation proctitis.
    • The sponge stick technique demonstrated a slightly higher success rate for initial bleeding control.
    • Both methods are viable, with careful consideration of potential complications.
