Usefulness of the pedicled omental graft in thoracic surgery.

A retrospective evaluation on the usefulness of the pedicled omental graft (POG) in treating problems associated with thoracic surgery is reported. The omentum has been long used to manage numerous intra-abdominal problems because of its excellent blood supply that could limit the spread of infection. The POG finds even greater application in extraperitoneal use because it is able to extend to all areas of the thorax. In this study, we reviewed 25 patients with omentopexy cases in our thoracic surgery unit over the last 19 years. Indications and usage of the POG were divided into two categories. As a preventive measure, the POGs were used to wrap tracheal and bronchial anastomoses. As a corrective treatment, the POGs were used to wrap perforated esophageal lesions and bronchial stumps and cover postoperative bronchial and pulmonary fistulas, repair chest walls, fill empyema cavities, and control osteomyelitis in the sternum and ribs. Uneventful and successful treatments were obtained in 22 cases (88%). Two patients died due to multiple organ failure followed by sepsis, and another due to respiratory failure. The POG was considered to be effective and useful in treating both potential and existing conditions often encountered in thoracic surgery.
