Negative pressure wound therapy does not decrease postoperative wound complications in patients undergoing mastectomy...

Area of Science:

• Surgical Oncology
• Wound Healing
• Medical Devices

Background:

• Mastectomy patients face high rates of wound complications.
• Negative pressure wound therapy (NPWT) shows promise for closed surgical incisions.
• Limited data exists on NPWT for closed mastectomy incisions.

Purpose of the Study:

• To evaluate the efficacy of NPWT in reducing postoperative complications after mastectomy.
• To compare wound complication rates between NPWT and conventional care in mastectomy patients.

Main Methods:

• Prospective study of 50 mastectomy patients treated with NPWT for seven days post-surgery.
• Comparison with a historical control group (111 patients) from a randomized controlled trial.
• Primary outcome: postoperative wound complications (infection, necrosis, dehiscence) within three months.

Main Results:

• Wound complication rates were 28% in the NPWT group versus 18.9% in the control group (OR=1.67).
• No statistically significant difference in unplanned hospital visits or clinically significant seroma (CSS) development.
• NPWT did not demonstrate a benefit in reducing complications for closed mastectomy incisions.

Conclusions:

• Avelle negative pressure wound therapy does not decrease postoperative wound complications after mastectomy.
• NPWT offers no significant advantage over standard care for preventing complications or seromas in closed mastectomy wounds.
