Investigations

Investigations

The investigation of a patient with PMP should include a high-resolution CT scan of the abdomen and pelvis with oral and intravenous contrast. A full colonoscopy should be performed to exclude a primary colorectal cancer. Laparos copy may provide additional staging information by allowing direct visualisation of the small bowel where radiologically occult miliary disease may be found. Ideally laparoscopy should be performed at a centre wher e subsequent CRS would be undertaken. Laparoscopy also facilitates tissue diagnosis, although this is not always necessary . In experienced centres the clinical and radiological features are often su ffi cient to establish a diagnosis of PMP .
