RESECTION OF PELVIC TUMOURS – HEMIPELVECTOMY OR INTERNAL HEMIPELVECTOMY

The purpose of this study is to compare functional results of hemipelvectomy and internal hemipelvectomy following resection of pelvic tumours. The emotional acceptance of such surgery is also examined. From 1998 to 2003, 19 male and 13 female patients, aged from 6 to 76 years, underwent hemipelvectomy, and 12 male and seven female patients, aged from 13 to 65 years, underwent internal hemipelvectomy. In the series as a whole, follow-up ranged from 1 to 156 months. Five patients with external hemipelvectomy, six with internal hemipelvectomy and one who underwent internal hemipelvectomy followed by external hemipelvectomy were evaluated functionally, clinically and psychologically. Patients expressed emotional concern about body image and mobility. Psychosocial adjustment was difficult for all patients, but some were able to overcome their difficulties more easily than others. Patients with internal hemipelvectomy rather than external hemipelvectomy had more difficulty adjusting emotionally. The site of the tumour and morbidity rates, which remain high when limb-sparing surgery is performed for pelvic tumours, are important considerations when deciding upon the type of surgery. Patients and their families need extensive preoperative psychological preparation and postoperative psychotherapy is imperative.
