Surgery for extraperitoneal pelvic neoplasms / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the methods of surgery for extraperitoneal pelvic neoplasms.</p><p><b>METHODS</b>Clinical data related to surgery of 84 cases of extraperitoneal pelvic neoplasms were extracted and retrospectively analyzed.</p><p><b>RESULTS</b>All 84 patients underwent operations, including one of them who received 4 operations within 6 months for resection of a single tumor. 58 abdominal, 16 buttock and 10 combined incisions were made in the series. Pelvic organs and structures were co-resected in 35 cases, including total pelvic exenteration in 2 cases and anterior pelvic exenteration in 2 cases. Common and/or external iliac vessels were resected and transplantations of artificial vessel were carried in 5 cases. Internal iliac arteries were ligated in 10 cases. The mean blood lose was 2 385 ml in our series and the largest was 15 000 ml. The complete resection rate of tumor was 81% for 84 operations and the largest resected tumor was 30 cm x 30 cm x 25 cm. There was no hospitalized death, and postoperative complication rate was 7% (6/84) in our series. Only 1 death were seen during the mean period of postoperative follow-up of 54 months, 22 operations were carried for 21 cases of recurrence, including 7 operations for 7 recurrences in a case within 12 years.</p><p><b>CONCLUSIONS</b>Making adequate abdominal or/and buttock incisions, exenterations of involved pelvic organs and structures, total pelvic exenteration if necessary, appropriate management of iliac vessels, planned re-operation for one tumor, and re-operation for recurrences are important methods for the treatment of extraperitoneal pelvic neoplasms.</p>
