Intravenous fluids are administered, especially if the blood pressure is low, and antibiotics are commenced. Empirical treatment with broad-spectrum antibiotics is usually necessary until it is known for certain which pathogen is causing the infection, and to which antibiotics it is sensitive. Combinations of penicillins and aminoglycosides are widely used, although ciprofloxacin has been shown to be effective in most cases, and may be preferred to aminoglycosides because of fewer side effects. Metronidazole is often added to specifically treat the anaerobic pathogens, especially in those who are very ill or at risk of anaerobic infections. Antibiotics are continued for 7–10 days. Drugs that increase the blood pressure (vasopressors) may also be required to counter the low blood pressure. Endoscopy
The definitive treatment for cholangitis is relief of the underlying biliary obstruction. This is usually deferred until 24–48 hours after admission, when the patient is stable and has shown some improvement with antibiotics, but may need to happen as an emergency in case of ongoing deterioration despite adequate treatment, or if antibiotics are not effective in reducing the signs of infection (which happens in 15% of cases).Endoscopic retrograde cholangiopancreatography (ERCP) is the most common approach in unblocking the bile duct. This involves endoscopy (passing a fiberoptic tube through the stomach into the duodenum), identification of the ampulla of Vater and insertion of a small tube into the bile duct.
If ORS is possible, pelvic should be performed to evaluate for a pelvic mass. [1]

Diagnosis
Surgical exploration and confirmation of possible ovarian tissue is required for the definitive diagnosis of ORS, and treatment by excision of the remnant ovarian tissue may be performed during the same procedure. For women who are not candidates for surgery, a clinical diagnosis can be made based on the symptoms and levels (follicle-stimulating hormone and estradiol, after bilateral oophorectomy) and/or findings consistent with the presence of residual ovarian tissue. Laparoscopy and histological assessment can aid in diagnosis. Treatment
Treatment for ovarian remnant  (ORS) is generally indicated for women with suspected ORS who have symptoms (such as  pain); have a pelvic mass; or need or desire complete removal of  to decrease the risk of ovarian  (for example, BRCA  ). The mainstay of treatment is surgery to remove the residual ovarian tissue. Women with ORS with a pelvic mass should have appropriate evaluation for malignancy (cancer). Hormonal therapy to suppress ovarian function is an alternative treatment for those who refuse surgery, or those who are not candidates for surgery. Medications may be used to treat ORS and include GnRH agonists, danazol, or progesterone. Epidemiology
The incidence of ovarian remnant syndrome is difficult to determine. The available data are limited to case reports or to retrospective case series. The best available data are from a study describing the frequency and outcome of laparoscopy in women with chronic pelvic pain and/or a pelvic mass who were found to have ovarian remnants.
