For the past two years, this technique has been used without complications in all patients in whom direct or random biopsies of the diaphragmatic peritoneal surfaces are indicated. Several advantages of this technique include: 1, specimens taken for biopsy from all peritoneal surfaces, including infracolic and pelvic, can be easily obtained in this manner; 2, surgical clips are inert, hemostatic and easy to apply; 3, in reassessment operations, previously placed clips lead the surgeon to areas where implants or occult metastases were initially found, and 4, the clips could potentially serve as anatomic markers in planning adjuvant treatment, especially irradiation therapy.
