Recent trends in breast reconstruction have transitioned toward the skin-sparing type of mastectomy and immediate reconstruction using autologous tissue. This study was designed to document trends in the management of patients with unilateral breast cancer and to determine how they influence management of the contralateral breast. All patients who underwent unilateral breast reconstruction at Emory University Hospitals from January of 1975 to December of 1999 were reviewed. The cohort was stratified by timing of reconstruction (immediate versus delayed), method of reconstruction, and mastectomy type (skin-sparing versus non-skin-sparing). The methods of reconstruction included implant, latissimus dorsi flap, and transverse rectus abdominis musculocutaneous (TRAM) flap. Contralateral procedures to achieve symmetry included augmentation, mastopexy, augmentation/mastopexy, and reduction. A total of 1394 patients were evaluated, including 689 delayed and 705 immediate reconstructions. Sixty-seven percent of delayed-reconstruction patients (462 of 689) had a symmetry procedure performed on the opposite breast, compared with 22 percent for the immediate-reconstruction patients (155 of 705) (p = 0.001). The percentage of times a contralateral procedure was performed was highest for implant reconstructions (89 percent delayed and 57 percent immediate) and lowest for TRAM flap reconstructions (59 percent delayed and 18 percent immediate). Augmentation mammaplasty was the most common symmetry procedure for implant reconstruction (41 percent), whereas reduction was the most common procedure for autologous tissue reconstruction (57 percent). Immediate unilateral breast reconstructions were stratified into non-skin-sparing mastectomy (n = 205) and skin-sparing mastectomy (n = 500). Thirty-four percent of patients with a non-skin-sparing mastectomy defect (70 of 205) underwent a contralateral breast procedure, compared with 17 percent of patients with a skin-sparing mastectomy defect (85 of 500) (p = 0.001). The percentage of times a contralateral procedure was performed in immediate reconstruction, stratified by mastectomy and reconstruction type, was only significant for TRAM flap reconstructions (25 versus 11 percent). Trends in the management of unilateral breast cancer from delayed to immediate reconstruction and from implants to autologous tissue have reduced the incidence of contralateral symmetry procedures. Reduction mammaplasty is the most common symmetry procedure used for autologous tissue reconstruction, with augmentation predominating when implants are used. The type of mastectomy also effects the management of the opposite breast, with skin-sparing mastectomy further reducing the incidence of contralateral procedures in immediate TRAM flap reconstruction, compared with non-skin-sparing mastectomy.
Post mastectomy breast reconstruction continues to evolve in both timing and technique; however, multiple surgical procedures are usually required. The purpose of this report was to determine the number of secondary procedures required to complete the breast reconstruction and factors that influence this process. All patients who underwent breast reconstruction at Emory University Hospital between 1975 and 2000 were reviewed. The end point and inclusion criterion was completion to nipple reconstruction. Secondary procedures were determined per patient for either unilateral or bilateral reconstructions, and defined as any surgical manipulation of the reconstructed breast, contralateral breast, or donor site. The cohort was stratified by timing and method of reconstruction. Additional variables included risk factors, radiation therapy, and complications. A total of 888 patients completed the reconstructive process (738 unilateral and 150 bilateral). The average number of secondary procedures was 3.99 for unilateral, and 5.54 for bilateral. Delayed reconstructions had a higher number of secondary procedures in both groups. Transverse rectus abdominus musculocutaneous flap reconstruction tended to have more secondary procedures than implant or latissimus dorsi with or without implant reconstructions. Radiation therapy increased the number of secondary procedures in unilateral (3.9 versus 4.6, P < 0.001) and in bilateral reconstructions (5.7 versus 6.4, P = 0.032). The number of secondary procedures also increased exponentially with the number of risk factors (0-4), and patients with any complication had a higher number of secondary procedures for unilateral (4.5 versus 3.6, P < 0.001) and bilateral reconstructions (6.4 versus 4.5, P < 0.001). Secondary breast and donor site procedures were used as an outcome measure to formulate comparisons. Autologous tissue reconstruction required more secondary procedures, likely in part to donor site revisions. Delayed reconstruction, the need for radiation therapy, any complication, and more risk factors significantly increased the number of secondary procedures required to complete the reconstructive process.
The presence of a preexisting subcostal incision alters the approach to breast reconstruction and is thought to predispose to donor site skin complications and flap loss. The purpose of this study was to determine whether the presence of a subcostal scar affects breast or donor site morbidity adversely after transverse rectus abdominis musculocutaneous (TRAM) flap breast reconstruction. Twenty-six patients with a right subcostal incision (group A) underwent TRAM flap breast reconstruction (13 immediate, 13 delayed). The average age was 51 years, and the patients had an average body mass index of 25.3. There were 15 right, 10 left, and 1 bilateral reconstruction (4 free flaps, 22 pedicled). Outcome measures were compared with 126 age- and risk-matched patients (group B) who underwent TRAM flap reconstruction without any preexisting abdominal scar. The average age in group B was 46.7 years, and the patients had an average body mass index of 24.8. The average length of stay in group A was 5.9 days, compared with 4.8 days in group B ( < 0.05). There were no significant differences in breast-related complications. Donor site complications were higher in group A, with abdominal wall skin necrosis being significantly higher in patients with a subcostal incision (25%) compared with those patients without abdominal wall scars (5%; = 0.02). Multivariate analysis revealed a 6.5-fold increase in donor site complications in patients with a subcostal incision and a smoking history ( < 0.05). When adjusted for radiation treatment, the increased incidence in donor site complication rate was only marginally significant ( = 0.08). TRAM flap breast reconstruction in patients with preexisting right subcostal scars is effective with certain technical modifications; however, there is a slight predisposition to increased abdominal wall complications. Smoking influenced outcome further in patients with a subcostal incision, stressing the importance of proper patient selection.
