Introduction: Pelvic exenteration is a highly invasive procedure, with a reported rate of 20%–80% for serious complications. Thus, the prevention of postoperative complications is a major issue. Many previous reports have emphasized the importance of filling the dead space to prevent postoperative complications. In addition to filling the dead space, we believe that achieving sufficient drainage is extremely important. In this paper, we present a new combined method of the extended rectus abdominis myocutaneous flap and vacuum drainage with multiple drains, which achieved a lower frequency of complications. Case Presentation: The subjects were 6 patients who underwent reconstruction following pelvic exenteration during a 7-year period between April 2005 and September 2013. We retrospectively measured the volume of the pelvic cavity and that of the rectus abdominis flap on lateral computed tomography (CT) scans to calculate the percentage of the dead space that was filled by the flap. There were no problems with flap engraftment in any of the patients. There were no serious complications, and no patient required additional surgery. The percentage of the dead space filled ranged from 25% to 46% (mean: 32%). Conclusion: The rectus flap + vacuum drainage method, which uses an extended rectus abdominis myocutaneous flap to decrease the pelvic dead space and multiple vacuum suction drains, was associated with the prevention of serious complications.
