Abstract

Background

Fistula-tract Laser Closure (FiLaC™) is a sphincter-saving technique for the treatment of anal fistulas that has been shown to be successful in the short and middle term. However, the long-term success rate is unknown. This study aimed to report long-term results in performing FiLaC™.

Methods

This study was performed as a retrospective observational study. Forty-five patients who underwent FiLaC™ between July 2010 and May 2014 were evaluated. In all cases, FiLaC™ was performed with a diode laser at a wavelength of 1470 nm by means of a radial fiber. Patients and fistula characteristics, previous treatments, healing rates, failures and postoperative incontinence were reviewed.

Results

Median follow-up time was 30 months (range 6–46 months). Thirty-five patients (78 %) had a history of previous surgery for their fistulas. Primary healing was observed in 32 patients (71.1 %), and the median healing time was 5 weeks (range 3–8 weeks). Eleven of the 13 failures (85 %) were early failures (persistent symptoms). No patient reported postoperative incontinence. The best healing rate was observed in patients who had been previously treated with loose seton (19/24, 79 %).

Conclusions

Long-term follow-up after FiLaC™ seems to confirm the favorable short-term success rates reported for this procedure. Although sealing of chronic anal fistulas may be obtained with FiLaC™ in a single treatment, our current strategy consists of placing a loose seton into the fistula tract a few weeks prior to laser treatment. Seton treatment facilitates the following laser procedure and seems to have favorable effects on healing.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

CME: 2 Punkte

Prof. Dr. med. Gregor Antoniadis Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

CME: 2 Punkte

Dr. med. Benjamin Meyknecht, PD Dr. med. Oliver Pieske Das Webinar S2e-Leitlinie „Distale Radiusfraktur“ beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
