Omentoplasty in the management of filarial lymphoedema.
A trial of omentoplasty was carried out on 20 patients with unilateral filarial lymphoedema to assess its role in the reduction of oedema volume after failed lymphonodo-venous shunt (LNVS) or as a primary procedure. Omentoplasty was done through a midline laparotomy. The omentum was mobilized from the colon, preserving both gastroepiploic vessels, and transferred to the thigh either through the lower end of the laparotomy incision or through a separate stab and placed subcutaneously in the upper third of the thigh. There was no operative mortality. Morbidity was mainly incisional hernia and superficial wound infection. Fourteen of 18 patients had more than 25% reduction in oedema volume during the immediate postoperative period, and 5 of the 18 had more than 50% reduction. However, there was a gradual loss of response with time. Age, gender, grade of lymphoedema, duration, and previous surgery did not influence the outcome. The incidence of incisional hernia could be reduced by transferring the omentum through the midline. There was a statistically significant reduction in postoperative adenolymphangitis attacks whether or not the oedema volume was reduced. In some patients the oedema was reduced sufficiently to permit subcutaneous excision of the lymphoedematous tissue. There appears to be a definite but limited role for omentoplasty in patients who have failed LNVS.
