Aim.To generalize and present current data on the development of approaches to hemorrhoidectomy, as well as to analyse the function of the rectal closing apparatus after surgery.Key findings.The haemorrhoid disease is one of the most common human diseases and the most common reason for visiting a coloproctologist. In Russia, the prevalence of haemorrhoids amounts to 130–145 people per 1,000 adult population, with its proportion in the structure of colon diseases varying from 34 to 41 %. Minimally invasive methods for treating such conditions have been shown to be effective in patients with 1–3 stage haemorrhoids. However, these methods have shown little value at stage 4 hemorrhoids, largely because they fail to affect all parts of the disease pathogenesis. Thus, hemorrhoidectomy remains to be the “gold standard” for stage 4 hemorrhoids treatment, which is aimed at eliminating the three main vascular collectors. Hemorrhoidectomy is accompanied by the risk of stricture and postoperative anal sphincter failure. In this regard, it is necessary to assess the functional state of the rectal closing apparatus after hemorrhoidectomy. Improving hemorrhoidectomy, for example, by the use of an ultrasonic scalpel, allows the hemorrhoidectomy to be performed without additional sewing of vessels and coagulation, and the injury of the anal sphincter to be minimized.Conclusion. The possibility of injuring the anal sphincter is a serious problem in anal surgery. Anal sphincter incontinence is a serious illness that exacerbates the patients’ social life. Unfortunately, the issue of anal sphincter incontinence after hemorrhoidectomy is under-investigated, resulting in few rehabilitation programs.

AIM: to improve the results of treatment in hemorrhoid Grade IV.PATIENTS AND METHODS: the prospective randomized study included 101 patients with combined hemorrhoids Grade IV were divided in two groups. Both groups were homogenous in age and gender. All patients underwent open hemorrhoidectomy with monopolar coagulation. Low-temperature argon plasma application was implemented in postoperative period as an additional option in the main group at 2, 4, 6, 8, 14, 21, 30 days after surgery. Visual Analogue Scale (VAS, 0 to 10 points) was used to assess pain intensity. Bacteriological and cytological tests performed at 2, 8, 14, 21, 30 days and then every 7 days until the wounds were completely healed. The area of the postoperative wound and the rate of healing were calculated using a planimetric method. Quality of life was assessed before surgery, and on days 8 and 30 using the SF-36 questionnaire.RESULTS: on the 30th day after surgery, cytology confirmed wound healing occurred in 38 (76.0%) patients of the main group and in 18(36.0%) patients in the control group, p = 0.0001. VAS score at day 8 after surgery was 3 (3; 4) and 4 (3; 5) points in main and control group, respectively, p = 0.00003. Quality of life measuring showed significant difference in the physical component between groups: 48 (44; 53) vs 42 (38; 48) points in the main and control group, respectively (p < 0.05). On the 30th day after the procedure, the physical component of the quality of life was 48 (44; 53) points in the patients of the main group, 42 (38; 48) — in the control group, p = 0.005. There was found significant difference in wound microbial content between groups: 104 vs 107 CFU on the 30th day after the surgery.CONCLUSION: the low-temperature argon plasma accelerates wound healing, as well as reduces the pain intensity. A significant antimicrobial effect was detected.

AIM: to assess late results of surgery for incomplete internal anal fistulas.PATIENTS AND METHODS: the prospective cohort study included 156 patients with in complete internal anal fistulas in 2014-2017.RESULTS: complete efficacy of the treatment was obtained in 132/147 (89.8%) patients, 106/117 (90.6%) revealed no anal incontinence (AI). Recurrence developed in 15/147 (10.2%) cases and 11/147 (7.5%) — anal incontinence. Newly developed incontinence was revealed in 7/117 (6.0%) patients: 6/117 (5.1%) had mild AI and 1/117 (0.9%) — moderate. The increase of AI degree showed 4/30 (13.3%) patients.CONCLUSION: a differentiated approach to anal fistulas surgery made it possible to minimize risk of incontinence and recurrence.

Aim: to improve the results of treatment of patients with hemorrhoidal disease of the 2nd and 3rd stages by using a diode laser with a wavelength of 1940 nm.Materials and methods. The study included 28 patients with hemorrhoids of the second or third stage. A new treatment method based on the use of a diode laser with a wavelength of 1940 nm was applied to all patients. This technique (laser hemorrhoidoplasty) provides for the thermal effect of laser radiation on the cavernous tissue of the internal hemorrhoid node and the terminal branches of the upper rectal artery. The intensity of postoperative pain syndrome was assessed and the clinical symptoms of hemorrhoidal disease manifestations were studied before and after surgery. To study the effectiveness of the proposed method and to assess the depth of thermal exposure to laser radiation, transrectal ultrasound with Dopplerography and pathomorphological examination were performed. The functional state of the rectal locking apparatus before surgery and in the postoperative period was assessed using sphincterometry. The quality of life of patients who underwent laser hemorrhoidoplasty was studied according to the SF 36 questionnaire.Results. Surgical intervention was performed under both local and spinal anesthesia. Intraoperative complications in the form of hemorrhoidal node bleeding were noted in 3 patients. In the early postoperative period, inflammatory edema of external hemorrhoids was diagnosed in 4 patients. The intensity of the pain syndrome was assessed on the VAS scale and by day 7 in 93 % of patients it did not exceed 1 point. All 28 patients were followed up within 1 to 6 months after the operation. All had no complaints characteristic of hemorrhoidal disease, no relapse of the disease was detected in any observation. Transrectal ultrasound with Dopplerography was performed, which made it possible to diagnose a 2–3-fold decrease in blood flow along the terminal branches of the upper rectal artery, and internal hemorrhoids determined earlier, before surgery, were not visualized already 1 month after surgery. According to sphincterometry, no violations of anal retention function were detected in all 28 patients.Conclusion. Surgical treatment of hemorrhoids of the 2nd and 3rd stages with the use of a diode laser with a wavelength of 1940 nm. with proper technical performance and the choice of optimal energy, it allows to achieve a good clinical effect. The proposed method of intervention ensures the absence of a pronounced pain syndrome, which does not lead to a significant decrease in the quality of life already in the early postoperative period and allows to shorten the period of labor rehabilitation. Laser hemorrhoidoplasty is a highly effective method of treating hemorrhoids at stages 2 and 3 of the disease and opens up the possibility of treatment on an outpatient basis.

Aim of review. To present literature data of the treatment of incomplete rectal fistulas with application of biological substances. Summary. Treatment of rectal fistulas remains burning issue in coloproctology due to unsatisfactory results of surgery resulting in high relapse rate, usually regardless of applied surgical method and high risk of severe complications as anal sphincter incompetence. This is why development of sparing methods of rectal fistula treatment that will allow to decrease intraoperative trauma of the anal sphincter at minimal risk of disease recurrence and, therefore, to prevent development of sphincter incompetence is important. Application of biological materials in rectal fistulas treatment result in reduction of the wound size, accelerates reparative processes and decreases degree of traumatization. Minimization of surgical impact on the anal sphincter allows repetitive application of biological materials up to the achievement of positive effect. Conclusion. Application of biological materials at sphincter-preserving technique provides decreased risk of development of postoperative anal sphincter incompetence.

Aim:to summarize the literature data on the treatment of rectal fistula using fibrin glue.Key findings:The prevalence of rectal fistula is about 9 cases per 100,000 population. Patients with rectal fistulas are frequently represented by the able-bodied middle-aged population group. The disease is extremely rarely observed in children and elderly people. Thus, this problem has a socially significant character. Fistula elimination is possible only by surgery, which is accompanied by the risk of fistula recurrence and the development of postoperative incontinence. In this regard, low-invasive techniques for the treatment of rectal fistulas, such as the use of fibrin glue, are being actively investigated.Conclusion:The use of fibrin glue as a sphincter-preserving technique eliminates the development of postoperative anal failure, while new technologies and materials aim to reduce the risk of the disease recurrence.
