Differential Diagnosis for Pus Discharge from C-Section Wound 9 Years Post-Operation
- Single Most Likely Diagnosis
- Chronic wound infection or sinus formation: This is the most likely diagnosis given the long-standing nature of the symptoms. A chronic infection can persist for years, especially if the wound was not properly healed or if there was a retained foreign body.
- Other Likely Diagnoses
- Incisional hernia with infection: An incisional hernia can occur years after a cesarean section and may become infected, leading to pus discharge.
- Suture granuloma or reaction: A granuloma or reaction to sutures used in the cesarean section can cause a chronic discharge.
- Epithelialized tract or fistula: An epithelialized tract or fistula can form between the skin and the uterus or other internal organs, leading to chronic discharge.
- Do Not Miss Diagnoses
- Uterine dehiscence or rupture: Although rare, uterine dehiscence or rupture can occur years after a cesarean section and may present with discharge or other symptoms. This is a life-threatening condition that requires immediate attention.
- Retained foreign body (e.g., surgical sponge): A retained foreign body can cause a chronic infection and discharge. This is a serious condition that requires prompt diagnosis and treatment.
- Rare Diagnoses
- Actinomycosis: A rare bacterial infection that can cause chronic discharge and abscesses.
- Tuberculous infection: A rare cause of chronic discharge and infection, especially in endemic areas.
- Malignancy (e.g., scar endometriosis): Rarely, a malignancy can occur in the scar tissue of a cesarean section, leading to discharge or other symptoms.
