Changes To The Abdominal Wall After DIEP Flap Breast Reconstruction

February 4, 2020 updated by: Kim Alexander Tønseth, Oslo University Hospital

Structural Changes In The Abdominal Wall After Deep Inferior Epigastric Perforator Flap Breast Reconstruction

The purpose of this study was to perform an evaluation of the structural changes in the abdominal wall after harvesting a DIEP flap in breast reconstruction.

14 women undergoing secondary, unilateral breast reconstruction were recruited to the study and underwent a 2 year postoperative CT scan of the abdomen (without contrast).

Structural changes were assessed by comparing the abdominal CT scans performed prior to surgery with the 2 year postoperative CT scans.

Detailed Description

The purpose of this study was to perform an evaluation of the structural changes in the abdominal wall after harvesting a DIEP flap in breast reconstruction.

14 women undergoing secondary, unilateral breast reconstruction were recruited to the study and underwent a 2 year postoperative CT scan of the abdomen (without contrast).

Structural changes were assessed by comparing the abdominal CT scans performed prior to surgery with the 2 year postoperative CT scans.

The following structural changes were evaluated at four specific levels of the abdomen by two radiologists (among the authors): 1) rectus diastasis, 2) thickness and width of the rectus muscles, 3) thickness of the adipose tissue, 4) hernias (in the zone between the xiphoid process and the symphysis).

The measurement levels chosen were: 1) 7 cm below the xiphoid process, 2) umbilicus level, 3) "central zone" (between level 2 and 4), 4) 5 cm above the symphysis

Statistical analysis were performed to see if the structural measurements were significantly different comparing preoperative CT versus 2 year postoperative CT.

Study Population

14 women consecutively undergoing secondary, unilateral breast reconstruction with a DIEP flap were identified and recruited to participate in the study. The patients were informed about of risks and benefits and gave written consent prior to participation. All smokers stopped smoking 4 weeks prior to surgery
