Background: Vulvoperineal defects resulting from surgical treatment of (pre)malignancies may result in reconstructive challenges. The vertical rectus abdominis muscle flap and, more recently, the fasciocutaneous lotus petal flap are often used for reconstruction in this area. The goal of this review is to compare the postoperative complications of application of these flaps. Methods: A comprehensive literature search of the PubMed, MEDLINE and Cochrane Library databases was performed until 6 June 2020. Search terms included the lotus petal flap, vertical rectus abdominis muscle flap and the vulvoperineal area. Articles were independently screened by two researchers according to the PRISMA-guidelines. Results: A total of 1074 citations were retrieved and reviewed, of which 55 were included for full text analysis. Following lotus petal flap reconstructions, the complication rate varied from 0.0% to 69.9%, with more complications concerning the recipient site compared with the donor site complications (26.0% versus 4.5%). Following vertical rectus abdominis muscle flap reconstructions the complication rate varied between 0.0% and 85.7% with almost twice the number of recipient site complications compared to donor site complications (37.1% versus 17.8%). Conclusions: Overall, the lotus petal flap has lower complication rates at both the donor and the recipient site compared with the vertical rectus abdominis muscle flap. When both options seem viable, the lotus petal flap procedure may be preferred on the basis of the reported lower complication rates.

Background: Lotus petal flaps are often used to reconstruct defects in the vulvoperineal area. Wound complications occur more often after surgery in the vulvoperineal area than in other areas of the body. Postoperative complications have a great impact on patients' well-being, length of hospital stay, care needed, and return to participation in daily life. Therefore, it is important to determine which patients are more prone to develop complications., Methods: All lotus petal flap reconstructions in our center between January 2004 and August 2014 were retrospectively reviewed. Complications were categorized by the Clavien-Dindo classification., Results: Ninety-three patients with 137 flaps were reviewed. The complication rates did not differ significantly between the reconstruction areas. In 30.1% of subjects, no complications were reported. A total of 51.7% of the subjects experienced Clavien-Dindo grade I or II complications, which required no or minor intervention. In 18.3% of subjects, intervention was required under general anesthesia (Clavien-Dindo grade IIIb complications), usually for debridement (64.7%). Donor site morbidity occurred in 14.0% of the subjects. The age group younger than 60 years showed a significantly higher rate of complications compared with the group older than 60 years (P = 0.015; odds ratio, 0.235; 95% confidence interval, 0.073-0.754)., Conclusions: This is the largest study to date on the complications of the lotus petal flap reconstruction. Complication rates did not differ between vulvar, perineal, and vulvoperineal reconstruction. Young patients seem to have a higher risk of developing complications.

After flexor tendon injury, most attention is given to the quality of the tendon repair and postoperative early passive dynamic mobilisation. Schemes for active mobilisation have been developed to prevent tendon adhesions and joint stiffness. This paper describes five patients to demonstrate the cerebral consequences of immobilisation allowing only passive movements, which implies a prolonged absence of actual motor commands. At the end of such immobilisation, PET imaging revealed reduced blood flow in specific motor areas, associated with temporary loss of efficient motor control. Effective motor control was regained after active flexion exercises which was reflected in normalised cerebral activations. This suggests that temporary, reversible cerebral dysfunction may affect the outcome of flexor tendon injuries.
