Overview
Surgery is the mainstay of treatment for Fournier gangrene.[1]. As the patients are cardiovascularly unstable, immediate resuscitation with intravenous fluids, colloids and inotropic agents are usually necessary.[2]
Surgery
Radical surgical debridement
Surgery is the mainstay of treatment for Fournier gangrene.[1]
- Indications include:[1]
- Patients displaying intense pain and skin color change such as edema and/or ecchymoses
- Signs of skin ischemia with blisters and bullae
- Altered mental status, hypotension, elevated band forms in the differential WBC count and metabolic acidosis.
- Immediate surgical referral remains the only method of reducing mortality and morbidity in Fournier gangrene patients.[3][4]
- As the patients are cardiovascularly unstable, immediate resuscitation with intravenous fluids, colloids and inotropic agents are usually necessary.[2]
- Effects of analgesia can be measured by documenting pain score regularly.
- Stop any NSAIDs on patient admission.
Procedure
- Radical debridement of areas of overt subcutaneous necrosis should be done in the operation theater in the lithotomy position to allow access to all perineal structures.
- Deep fascia and muscle are rarely involved, thus debridement is usually not required.
- Separation of the skin and subcutaneous tissue with a hemostat has been recommended to define the limits of excision. Debridement is stopped where these tissues do not separate easily.
Fecal and urinary diversion
- Urinary or fecal diversion is required to treat an underlying condition or prevent wound contamination.[5]
- When there is gross urinary extravasation or periurethral inflammation, suprapubic cystostomy is required. A urinary catheter is used in milder cases.
- Colostomy is required when there is gross sphincter infection or colonic or rectal perforation.
- Testes are temporarily implanted into subcutaneous tissue pouch (medial thigh or lower abdomen) until healing or reconstruction is complete.
- Orchidectomy is performed if there is any pre-existing epididymo-orchitis or scrotal abscess.
Plastic reconstruction
- The split thickness skin graft is a commonly used technique for reconstructive surgery. For large defects, rotational or free myocutaneous flaps and omental flaps are used to cover larger defects.[5]
Wound management
- The wound is monitored closely after surgery.
- Multiple surgical debridement are required with an average of 3.5 procedures per patient.[6]
- Sodium hypochlorite or hydrogen peroxide are used post-operatively for topical application.[7]
- Lyophilized collagenase (an enzyme that digests and debrides necrotic tissues) is used for enzymatic debridement twice daily until definite reconstruction can be performed.[8]
Vacuum-assisted closure device
The vacuum assisted closure device is used for faster and effective wound closure.[9][1] This devices helps wound healing by absorbing excess exudates, reducing localized edema, and finally drawing wound edges together.
