The aim – to analyze the results of treatment of patients with combined pathology of the anal canal and rectum using Surgitron radio wave surgery and high-frequency electrosurgery "KLS Martin". Materials and methods. The analysis of surgical treatment of 236 patients with combined anal canal and rectum with Surgitron radio wave surgery, 50 patients using KLS Martin high-frequency electrosurgery and 112 patients who have been traditionally operated using a metal scalpel. After surgical interventions using radio-wave and high-frequency electrosurgery devices, morphological examination of tissues was conducted to study the depth of their necrosis. Results. It has been established that the use of Surgitron, as well as the high-frequency electrosurgical apparatus "KLS Martin", reduces the duration of the surgery to 15 ± 5 minutes, reduces the volume of blood loss to 20 ± 10 ml, the need for narcotic analgesics to 2 ± 1 ml, and terms of inpatient treatment of patients up to 4 ± 1 day. The results of the morphological study indicate that the application of the above-mentioned surgical techniques leads to a negligible depth of tissue necrosis from 0.165 ± 0.11 mm using the Surgitron apparatus to 0.192 ± 0.12 mm when used with the KLS Martin apparatus, ensuring cosmetic operations. Conclusions. The use of the Surgitron radio-wave surgery and the KLS Martin electrosurgical apparatus for the treatment of patients with combined pathology of the anal canal and rectum due to insignificant tissue effects contributes to reducing the duration of the operation, reducing the volume of intraoperative blood loss, significantly reducing the pain in the postoperative period, reduction of the terms of inpatient treatment of patients, which determines their rapid medical and social rehabilitation. Also due to the minimal effect on the tissue, the healing of the postoperative wound is faster, which contributes to the formation of a delicate elastic scar and prevents the formation of scar strictures of the anal canal, as well as insufficiency of the anal sphincter in the postoperative period.

Objective. To evaluate the effectiveness of surgical treatment of anal canal and rectum combined pathology, through combined surgical interventions using modern electro- and radiosurgical technologies. Materials and methods. A comparative evaluation of the results of surgical treatment of 681 patients with combined pathology of the anal canal and rectum, who underwent combined single-stage operations using high-frequency electrosurgery and radio-wave surgery. Results. In case of application the device for radio-wave surgery "Surgitron", and also devices of high-frequency electrosurgery "ERBE ICC 200", "EFA", "KLS Martin" duration of operation is reduced to (15 - 25 ± 3) minutes, volume of blood loss decreases to (15 ± 6) ml, the need for narcotic analgesics decreases up to (2 ± 1) ml, the duration of inpatient treatment was reduced up to (4 ± 1) days. Conclusions. The use of modern radio- and electrosurgical technologies for the treatment of combined anorectal pathology prevents the occurrence of anal canal strictures and scarring of the perianal areas, causing the cosmeticity of combined operations.

AbstractTo report the experience and advantageous effects of high-frequency radio wave electrocautery in modified Hotz operations for epiblepharon, We reviewed the records of all pediatric patients who underwent a modified Hotz operation with the use of high-frequency radio wave electrocautery (Ellman Surgitron Dual Frequency RF S5; Ellman International, Inc, Hewlett, NY) for epiblepharon between March 2016 and September 2019 at Korea University Guro Hospital. We evaluated the success rate, complications, recurrence rate and degree of satisfaction of our technique. Information from the medical records was collected, including demographics, ocular symptoms, severity of keratopathy, operation time, success/recurrence rate, and complications. 133 patients (98.52%) showed good correction of epiblepharon without complications or unpleasant cosmetic problems during 3 months of median follow-up period. Two patients (1.48%) showed recurrent corneociliary touch, but the degree was very mild and re-operation was not performed. One patient showed mild ectropion on his left lower eyelid, but the patient recovered well without operation. For complications, suture abscess and granulation were the most common, 3 cases in each, but all of those were temporary and resolved with conservative management. The approach with electrocautery for epiblepharon allows precise and fast incision of the lower eyelid, little bleeding, and minimal scarring. Surgical outcomes associated with the modified Hotz operation with electrocautery were consistent with previous studies.

The Difference

On the basis of propagation the characteristics of Multi-hop High-Frequency Radio waves in Marine environment, the modeling and analysis method of ocean signal reflection model are firstly introduced from the attenuation of the radio wave. Then the difference between the influence of ocean and earth on wireless communication is studied. By studying the influence of ship on the loss of radio wave propagation, the original ocean model is improved. Finally, an ocean signal reflection model suitable for different marine environments is obtained.
