Current developments for pelvic exenteration in gynecologic oncology.
OBJECTIVE
The present review aims to update new techniques of pelvic exenteration including minimal invasive surgery, and discuss other aspects of this radical surgery, including worldwide differences.


RESULTS
Major advances are made since the first description of pelvic exenteration and the operation is still under evolution. Explorative laparoscopy prior to exenteration is a valuable alternative to laparotomy to elect candidates for pelvic exenteration. There are considerable differences with respect to indications, contraindications, preoperative staging and adjuvant therapy after exenteration in different countries. Advances in laparoscopic instruments also led to the laparoscopic exenteration. The main limiting step of the operation is urinary diversion. New techniques of laparoscopic-assisted and robotic-assisted techniques of urinary diversion have been reported that decrease the operation time. Vascularized muscle flaps are preferred by many surgeons to fill the empty pelvis and provide an acceptable vaginal reconstruction. J-pouch seems to be a safer technique than end-to-end coloanal anastomosis for bowel reconstruction. Developments in the bioengineering tissue for pelvic reconstruction are required.


CONCLUSIONS
Laparoscopy has the advantages of decreased blood loss, improved convalescence, lower incidence of wound infection and incisional hernia, short recovery periods, rapid return of bowel function, better pain control and improved cosmetics compared with laparotomy for pelvic exenteration. Magnification and improved visualization permits en-bloc dissection of tumor and good anastomosis technique. New techniques of urinary diversion, orthotopic neobladder and coloanal are promising.
