Closure or reduction of the donor defect of a sural flap with a purse-string suture: Long-term results

Abstract

We aimed to reduce the defect with a purse-string suture to minimise the deformity of the flap donor area and to assess the later efficiency at long-term follow-up. We studied 20 patients who required a sural flap for the reconstruction of defects of the lower extremity. The mean (SD) area of the donor defect was roughly 28.7 (20.3) cm². The mean (SD) defect area after closure with a purse-string was 8.2 (5.8) cm² (p < 0.001). The measurements made in the third year were 8.4 (5.3) cm². The purse-string can be used successfully in the distal lower extremity, the long-term cosmetic outcome is good, and the scar has not expanded since the postoperative period.     

Improvisations in classic and modified techniques of flap surgery to improve the success rate for pressure ulcer healing in patients with spinal cord injury

The recurrence of pressure ulcers (PrUs) and dehiscence of reconstructive flap have always been a problem. The present study aimed to evaluate the results of reconstructive flap surgeries in patients with spinal cord injury (SCI) having PrUs, using classic and modified flaps with improvisations to decrease wound dehiscence, flap necrosis and tension in flap. This is a prospective clinical study. The setting was a tertiary care centre in northern India. Thirty‐five patients with SCI having 37 stage III and IV PrUs. PrUs were treated using classic and modified flaps with improvisations. The outcome was evaluated using criteria of wound dehiscence, flap necrosis and recurrence. The results of flap surgery were excellent in 32 (86·48%) patients, good in 4 (10·81%) patients and poor in 1 (2·7%) patient. Partial flap necrosis (2·7%), low incidence of PrU recurrence rate at flap site (5·4%) and overall PrU recurrence (11·4%) were the complications observed. Improvisation of classic and modified techniques of flap surgeries along with reinforcement of general care principles of paraplegia can be effective in minimising complications often associated with PrU reconstructive surgery thus improving the ultimate outcome.     

Correction of hypospadias with a vertical preputial island flap: the Göteborg experience of 47 patients

We report the follow-up of 47 patients with penile hypospadias who were treated by the Scuderi procedure between 1988 and 1998 at Sahlgrenska University Hospital, Göteborg, Sweden. Forty of the patients (85%) had had no previous operations, while the remaining seven had had meatotomy with chordectomy only, or an unsuccessful Dennis-Browne procedure. Hypospadias was distal in 35 (74%), mediopenile in 8 (17%), and proximal in 4 (9%); 21 (45%) showed signs of curvature. After a Scuderi urethroplasty one patient developed a fistula (2%) and 4 developed mild stenosis. The early success rate was therefore 42/47 (89%) and this later increased to 46/47 (98%) after non-surgical treatment of the stenoses. The results support the use of the Scuderi procedure for correction of primary and secondary penile hypospadias with a low complication rate.     

MatriDerm Decreases Donor Site Morbidity After Radial Forearm Free Flap Harvest in Transgender Surgery

BackgroundPhalloplasty with the radial forearm free flap is associated with a large donor site defect.AimTo compare two methods of donor site closure for functional and cosmetic long-term results: full-thickness skin grafting vs split-thickness skin grafting with MatriDerm.MethodsThirty-seven transgender patients had a neophallus created from a radial forearm free flap, and all were operated on by the same senior surgeon. Eight patients had their donor site defect closed by total skin grafting and 29 patients, operated on after 2009, received a split-thickness skin graft with MatriDerm closure. All 37 patients were evaluated by questionnaire and by careful clinical examination. Pressure perception was assessed with the Semmes-Weinstein monofilament test. Sensory recovery, skin quality, and cosmetic result also were compared. The contralateral arm was used as the control.OutcomesPressure perception values showed better sensory return in the MatriDerm group. Split-thickness skin grafting with MatriDerm achieved superior results in skin sensibility, superficial radial nerve recovery, and cosmetic aspect.ResultsOur findings support the hypothesis that MatriDerm can be used to preserve sensory function and decrease morbidity of the donor site.Clinical ImplicationsThe use of a dermal substitute decreases the morbidity of the forearm free flap donor site.Strengths and LimitationsThe strength of this study is its retrospective nature conducted of a prospectively maintained database of 37 consecutive radial forearm free flaps with superimposable dimensions and location performed by the same surgeon, thus limiting biases. A limitation is its small sample (particularly for the control group).ConclusionOur experience showed that the combination of a split-thickness skin graft with MatriDerm substantially decreases postoperative complications at the donor site defect on the forearm of transgender patients.Watfa W, di Summa PG, Meuli J, et al.
