A Systematic Review and Meta-analysis on Omentoplasty for the Management of Abdominoperineal Defects in Patients Treated for Cancer

Objective: The objective of this systematic review and meta-analysis was to examine the effects of omentoplasty on pelviperineal morbidity following abdominoperineal resection (APR) in patients with cancer. Background: Recent studies have questioned the use of omentoplasty for the prevention of perineal wound complications. Methods: A systematic review of published literature since 2000 on the use of omentoplasty during APR for cancer was undertaken. The authors were requested to share their source patient data. Meta-analyses were conducted using a random-effects model. Results: Fourteen studies comprising 1894 patients (n ¼ 839 omentoplasty) were included. The majority had APR for rectal cancer (87%). Omentoplasty was not significantly associated with the risk of presacral abscess formation in the overall population (RR 1.11; 95% CI 0.79–1.56), nor in planned subgroup analysis (n ¼ 758) of APR with primary perineal closure for nonlocally advanced rectal cancer (RR 1.06; 95% CI 0.68–1.64). No overall differences were found for complicated perineal wound healing within 30 days (RR 1.30; 95% CI 0.92–1.82), chronic perineal sinus (RR 1.08; 95% CI 0.53–2.20), and pelviperineal complication necessitating reoperation (RR 1.06; 95% CI 0.80– 1.42) as well. An increased risk of developing a perineal hernia was found for patients submitted to omentoplasty (RR 1.85; 95% CI 1.26–2.72). Complications related to the omentoplasty were reported in 4.6% (95% CI 2.5%– 8.6%). Conclusions: This meta-analysis revealed no beneficial effect of omentoplasty on presacral abscess formation and perineal wound healing after APR, while it increases the likelihood of developing a perineal hernia. These findings do not support the routine use of omentoplasty in APR for cancer

Fasciocutaneous Lotus Petal Flap for Perineal Wound Reconstruction after Extralevator Abdominoperineal Excision:Application for Reconstruction of the Pelvic Floor and Creation of a Neovagina

The extralevator abdominoperineal excision (ELAPE) procedure creates an extensive soft tissue defect of the pelvic floor. It has been suggested that primary reconstruction reduces the risk of wound infection and delayed wound healing in this high-risk area. Use of myocutaneous flaps or omentoplasty are associated with functional limitations and complications. We performed the perineal variant of the lotus petal flap, which was originally described for vulvar reconstruction. We aimed to verify if application of the lotus petal flap in pelvic floor reconstruction after ELAPE meets the goals of an ideal reconstruction. We performed a retrospective study of 28 patients who underwent the lotus petal flap procedure for pelvic floor reconstruction after ELAPE between January 2011 and March 2014. Median age was 62.1 years and 78.6 % of patients were female. In most patients the tumor was preoperatively irradiated (89.3 %) and in 28.6 % of the reconstructions a biological mesh was applied. No total flap loss occurred. Six (21.4 %) patients had no complications, while 13 (46.4 %) patients had minor complications (Clavien-Dindo grade I-II). Reoperation (Clavien-Dindo grade IIIb) was performed in nine patients (32.1 %), three of whom required a second lotus petal flap reconstruction. Median time until wound healing was 14 weeks. No additional surgery was performed for aesthetic problems. Reconstruction of the pelvic floor after ELAPE using the fasciocutaneous lotus petal flap has limited major complications, but still with a high incidence of minor wound complications. This retrospective cohort study shows limited consequences on form and function

Quality of Life and Sexual Functioning After Vulvar Reconstruction With the Lotus Petal Flap

Objective Resection of (pre) malignant lesions in the vulvoperineal area may result in large defects that cannot be closed primarily. The lotus petal flap technique is widely used for reconstruction. The aim of this study was to evaluate both quality of life (QoL) and sexual functioning of patients who underwent the lotus petal flap procedure, because no data are available on this topic. Methods A cross-sectional study was performed on all eligible patients (N = 38) who underwent the lotus petal flap procedure between 2005 and 2016. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30, Female Sexual Function Index, and Body Image Scale were used to evaluate QoL and sexual functioning. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and Female Sexual Function Index scores were compared with scores of age-matched healthy women. Results Twenty-six patients (68%) responded. The mean (SD) age was 65.5 (16.3) years, and the median follow-up time was 38.5 months (range 16-141 months). Quality of life scores were lower compared with healthy women in the domains physical, role, and social functioning. Sexual activity rates were comparable with healthy women; however, sexual functioning was worse. Although patients were satisfied about their sexual life, pain was reported. Conclusions Patients who underwent vulvar reconstructive surgery with lotus petal flaps seem to have a lower QoL compared with healthy women. Patients report more pain during sexual activity but are satisfied about their sexual functioning. These results should be included in preoperative counseling and follow-up of future patients eligible for vulvar reconstruction with a lotus petal flap
