Heip,    my husband was diagnosed with a peritoneal cyst about two years ago,   he was rushed into emergency surgery to have it opened to drain.  It has recurred at least six more times (lost count) of which 4 required surgery.  He has been seen by a surgeon,  who quarterized (sp) the last site (between his scrotum and rectum)  who suggested he see an gastroenterologist who did a colonoscopy and a cat scan,  but found nothing.   He in turn recommended he see a dermatologist!  All the while this thing is leaking blood/pus and will build up only to open up when he least expects it.   We are beside ourselves.  Who would you recommend we see to make a diagnosis and solve his problem.
Hi, It could be a wound infection or abscess. Consult a general surgeon and get evaluated. Thorough wound debridement is required. All the pus debris has to be removed and antibiotics might be required. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
