The brand new July problem of Techniques in Coloproctology boasts two records regarding the laser treatment out of fistula-in-ano: an editorial from the Giamundo (Laser facial treatment to have anal fistulas: do you know the pitfalls?) and you will exclusive post of the de- Bonnechose et al. (Laser beam ablation regarding fistula area (LAFT) and you may cutting-edge fistula-in-ano: “an appropriate sign” has become sharper…).
To summarize all the Authors affirmed your fistula-in-ano laser facial treatment is an effective rectal sphincter-rescuing techniques and the rate of success is going to be in contrast to the newest almost every other advanced rectal fistulas rectal sphincter sparing process (fibrin adhesive, plugs)
Area of the indication of the strategy ‘s the therapy of large or complex rectal fistulas, where almost every other surgical procedures could possibly get impact the fresh new continence.
Just like the within the Books there was an excellent variability from the overall performance in the method – in particular Giamundo profile a recuperation rates out-of 71,1% [Giamundo ainsi que al. Colorect Dis 2014], whenever you are de Bonnechose regarding forty-two,6% – the purpose of the brand new Experts is to try to check out the this new predictive products out-of victory otherwise failure out-of laser skin treatment to have fistula-in-ano.
New customers commonly exactly similar ranging from knowledge: part of the biases may be the higher variability in the method of, length and you can sized this new fistulas, the size of the inner opening therefore the ratio away from inter-sphincteric, trans-sphincteric or supra-sphincteric system.
- fistula system length
- fistula diameter (less efficient over 4-5 mm)
- internal starting size
The newest Authors agree with the desire out-of fistula area preparation once the a bridge-to-procedures that have abscesses drainage, fistula curettage and placement of a loose seton, that will result in the synthesis of fibrotic muscle and you may fistula quality.
As the LAFT are 
a blind techniques, various other crucial area ‘s the evaluation of your quantity of the fresh new requisite times towards the shrinkage, with regards to complete number of opportunity administered and of amount of your time put per centimeter away from fistula. The final is hard to-be counted but Giamundo thinks one to is more significative versus total number of opportunity given during the method.
- fistulas demanding less than eight hundred J
- fistulas requiring more eight hundred J
In the end, when we thought just like the end-point the newest recurrence price, genuine recurrence have to be differentiated off low-recovery or chronic fistula
Fistulas demanding lower than eight hundred J got a substantially high data recovery price (65%) than the fistulas demanding more than eight hundred J (32%): this is informed me by the huge diameter fistulas which need far more times to-be closed otherwise of the “overburning” effect of excessively energy.
Some other questionable section is the treatment of the inner orifice: regarding research by Bonnechose the interior orifice wasn’t signed, but in people having large interior beginning (bigger than the newest probe) the fresh new heling rates are straight down (15.4%). Because one to both Author highly recommend the brand new closing out of an extensive inner opening which have an improvements flap.
Laparoscopic proper hemicolectomy (LRHC) is a type of performed techniques that is sensed by many people so you’re able to feel a basic out-of care regarding treatment of harmless and malignant disorder of one’s correct colon, enabling shorter recuperation which have analogous oncological overall performance in comparison to open processes [van Oostendorp et al. Surg Endosc. 2017].
Extracorporeal (EC) and intracorporeal (IC) anastomosis was basically discussed getting ileocolic anastomosis: to execute EC anastomosis a greater mobilization of one’s colon to the your body, mesenteric tractions and you may exteriorization of your intestinal owing to midline periumbilical cut are needed. On the other hand, IC anastomosis does not require intestinal exteriorization plus the resected part of your own colon will be brought because of an effective midline vertical incision otherwise an effective Pfannenstiel incision; not, it is technically demanding and requires enhances laparoscopic feel [Ricci C mais aussi al. Langenbecks Arch Surg. 2017].
