The laparoscope has become an important tool in the diagnosis of benign and malignant condition in the abdominal cavity. Laparoscopy indicated for patients with malignant disease may show either primary or metastatic malignant disease within the abdomen. In current clinical practice, management strategies for intra-abdominal malignancies have become increasingly sophisticated. As result, it is critically important that disease staging be accurate and effective. Despite the many preoperative radiological staging modalities available such as CT, MRI and PET, scan there often exists a small but significant marginal error between preoperative diagnosis and surgical finding at laparatomy. CT documented the primary mass lesion in all patients (100%). CT showed intra-abdominal metastatic lesions in 7 patients (17.5%). The primary in this: 2 colorectal carcinoma, 2 bladder carcinoma, 1 gastric, 1 biliary, and 1overian. The intraperitoneal metastesis in this 7 patients. In 5 patients out of the 11 patients with HCC. Laparoscopic was not done for this last 5 patients as they were considered indicate for palliative non surgical treatment. Diagnostic laparoscopy was done for 35 patients who were considered to be candidate's for surgery, either curative or palliative resection or bypass operation. Laparoscopy documented the findings of CT in all patients. However laparoscopy discovered the following findings which was not documented in CT. Conclusion : CT scan and diagnostic laparoscopy are very valuable tools in diagnosis and staging of intra-abdominal malignancies. They are complementary and not competitive.
