The best surgical treatment for high cryptoglandular perianal fistulas could not be identified. More randomized controlled trials are needed to find the best treatment. The mucosa advancement flap is the most investigated technique available.
No conclusion about the best surgical intervention for rectovaginal fistulas could be formulated. More large studies of high quality are needed to find the best treatment for rectovaginal fistulas. A design for these high-quality studies was formulated.
Over the past two decades, the risk of developing a perianal fistula was stable, as well as its recurrence rate, underlining the lasting need for improving treatment strategies for this invalidating condition.
The use of pulsed electromagnetic fields (PEMF) to stimulate bone growth has been recommended as an alternative to the surgical treatment of ununited scaphoid fractures, but has never been examined in acute fractures. We hypothesised that the use of PEMF in acute scaphoid fractures would accelerate the time to union by 30% in a randomised, double-blind, placebo-controlled, multicentre trial. A total of 53 patients in three different medical centres with a unilateral undisplaced acute scaphoid fracture were randomly assigned to receive either treatment with PEMF (n = 24) or a placebo (n = 29). The clinical and radiological outcomes were assessed at four, six, nine, 12, 24 and 52 weeks. A log-rank analysis showed that neither time to clinical and radiological union nor the functional outcome differed significantly between the groups. The clinical assessment of union indicated that at six weeks tenderness in the anatomic snuffbox (p = 0.03) as well as tenderness on longitudinal compression of the scaphoid (p = 0.008) differed significantly in favour of the placebo group. We conclude that stimulation of bone growth by PEMF has no additional value in the conservative treatment of acute scaphoid fractures.
This study shows it is safe, after c-VATS (bi-)lobectomy, to remove the chest tube within 24 h in 58.8%, and within 48 h in 82.5% of patients. As was also shown in other studies, this leads to shorter length of hospital stays, lower costs, and most importantly, reduces patient morbidity without the added risk of complications.
Fistulotomy seems to be associated with a healing rate of 0.81 (95% CI 0.71-0.85) after 5 years. However, major incontinence is still reported by 26.8% of patients and only 26.3% of patients had a perfect continence status.
BackgroundHealing rates after surgical closure for high perianal fistula in patients with Crohn’s disease are even more disappointing than in patients with cryptoglandular fistulas. The objective was to improve healing rates by combining the well-known mucosal advancement flap with platelet-rich plasma.MethodsA prospective pilot study was conducted in one tertiary referral centre. Consecutive patients with primary or recurrent Crohn’s disease-related high perianal fistulas, defined as involving the middle and/or upper third parts of the anal sphincter complex, were included. A staged procedure was performed with non-cutting seton treatment for 3 months first, followed by a mucosal advancement flap with injection of platelet-rich plasma into the fistula tract.ResultsTen consecutive patients were operated on between 2009 and 2014. Half (50 %) of the patients had undergone previous fistula surgery. Mean follow-up was 23.3 months (SD 13.0). Healing of the fistula was 70 % (95 % confidence interval, 33–89 %) at 1 year. One (10 %) patient had a recurrence, and in two (20 %) patients, the fistula was persistent after treatment. An abscess occurred in one (10 %) patient. The median post-operative Vaizey score was 8.0 (range 0–21), indicating a moderate to severe continence impairment.ConclusionsThe results of combining the mucosal advancement flap with platelet-rich plasma in patients with Crohn’s disease-related high perianal fistulas are moderate with a healing rate of 70 %. Further investigation is needed to determine the benefits and risks on continence status for this technique in this patient population.
The long-term outcome results of patients with primary and recurrent high cryptoglandular perianal fistulas treated with a seton followed by mucosal advancement flap and platelet-rich plasma show low recurrence, complication, and incontinence rates. Therefore, this technique seems to be a valid option as treatment. Larger and preferably randomized controlled studies are needed to further explore this surgical technique.
