Laser Coagulation of Pilonidal Sinus With/Without Intraoperative Ultrasound Control (LCPSwUsC)

Laser Coagulation in the Treatment of Pilonidal Sinus With Intraoperative Ultrasound Control: Multicenter Prospective Randomized Trial.

LASER COAGULATION OF THE PILONIDAL SINUS WITH INTRAOPERATIVE US CONTROL: PROTOCOL FOR A PROSPECTIVE MULTICENTER RANDOMIZED CLINICAL STUDY.

Adaptive randomized controlled equivalence study with one planned non-blinded interim analysis.

Studie Overzicht

Gedetailleerde beschrijving

When analyzing the literature data, we did not find any publications that assess the quality of this operation. The technical characteristics of laser radiation, such as power, mode, amount of energy transferred, and type of fiber, are considered in all publications, which is an objective criterion. On the other hand, the surgeon's mechanical treatment and laser exposure of the internal lining of the pilonidal cyst do not have clear criteria for analysis. An intraoperative ultrasound examination can visualize the position of the surgical instrument in the sinus cavity, providing an objective confirmation of the completeness of the surgical intervention. We have proposed criteria for the quality of mechanical and laser treatment of the pilonidal sinus duct based on intraoperative ultrasound examination: the location of the instrument in the lumen of the cyst cavity; the instrument is passed along the entire length of the pilonidal sinus duct.

Standard management protocol: the operation is performed under local infiltration anesthesia, with access from 1-2 points using a 4-6 mm skin trepan. Next, a button probe and a sharp Volkmann spoon are used for probing. Finally, the working part of the light guide is inserted, and ultrasound monitoring is performed to ensure proper orientation of the light guide throughout the pilonidal sinus passage and secondary passages. After that, the sinus is treated with a laser having the following characteristics: wavelength 1940 nm; end-fire; power 9 W; in constant mode. Repeated mechanical and laser treatment is performed with the same laser radiation characteristics, without ultrasonic control. The calculation of the total energy (both effects) does not exceed 200 J per cm of the sinus length.
