Background
To obtain a clear surgical margin, abdominoperineal excision (APE) for rectal cancer frequently leaves a large perineal defect surrounded by irradiated tissue. A vertical rectus abdominis myocutaneous (VRAM) flap may facilitate healing of this wound. The current study aims to determine the effect of VRAM flap perineal reconstruction following APE on patient quality of life (QOL).
Methods
This is a retrospective cohort study from a prospectively collected database. Data on QOL were assessed via telephone questionnaire using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30, EORTC QLQ-C29 and the Cleveland Clinic QOL questionnaires.
Results
Twenty-seven patients underwent primary perineal closure, and 12 patients underwent a VRAM flap perineal reconstruction. The mean duration of follow-up was 16.8 months. Overall, there was no significant difference in the Cleveland Clinic QOL score between groups (VRAM vs. no VRAM: 0.7 ± 0.2 vs. 0.7 ± 0.2, p 0.735). Patients in the VRAM group had lower levels of fatigue (5.5 ± 9.9 vs. 23.6 ± 19.2, p 0.004). Patients in the VRAM group had reduced sore skin scores around the stoma site (11.0 ± 16.2 vs. 31.8 ± 31.1, p 0.036). VRAM flap was associated with an increased incidence of abdominal wall hernia (VRAM vs. no VRAM: 25 % vs. 0 %, p 0.024).
Conclusions
This study is limited by its non-randomized retrospective design and relatively small sample size. A significant difference in patient QOL was not demonstrated between VRAM flap and primary perineal closure after APE for rectal cancer. Further studies in this area are warranted.
