Chances may vary 15-50% but if the patient suffering from chemical paritonitis need again laproscopy or laprotomy to remove the cyst contents that cause irritation in the peritonium. Until unless you remove irritant it is difficult to control infection and inflammation. Please consult your surgeon immediately he will examine and treat you accordingly.
