A prospective randomized study comparing retroperitoneal drainage with no drainage and no peritonization following radical hysterectomy and pelvic lymphadenectomy for invasive cervical cancer.

OBJECTIVE

To evaluate the postoperative morbidity and lymphocyst formation in invasive cervical cancer patients undergoing radical hysterectomy and pelvic lymphadenectomy (RHPL) with no drainage and no peritonization compared with retroperitoneal drainage and peritonization.

METHODS

Between July 1999 and May 2000, 100 patients with stage IA-IIA cervical cancer undergoing RHPL in Chiang Mai University Hospital were prospectively randomized to receive either no peritonization and no drainage (Group A = 48 cases) or retroperitoneal drainage and peritonization (Group B = 52 cases). Perioperative data and morbidity were recorded. Transabdominal and transvaginal sonography were performed at 4, 8 and 12 weeks postoperatively to detect lymphocyst formation.

RESULTS

Both groups were similar regarding age, size and gross appearance of tumor, tumor histology and stage. There was no difference between groups in respect of operative time, need for blood transfusion, intraoperative complications, hospital stay, number of nodes removed, nodal metastases, and need for adjuvant radiation and chemotherapy. Asymptomatic lymphocysts were sonographically detected at 4, 8 and 12 weeks postoperatively in 3 (6.8%), 2 (4.6%), and 3 (7.7%) of 44, 43, and 39 patients, respectively in Group A, whereas none was found in Group B (P = 0.2). No significant difference was found in term of postoperative morbidity in the two groups.

CONCLUSION

Routine retroperitoneal drainage and peritonization after RHPL for invasive cervical cancer can be safely omitted.
