Symmary. About 300 surgical treatments for hemorrhoids are known now. The most common method in the world remains the Milligan-Morgan operation and its numerous modifications. These surgical interventions are essential in the choice of surgical treatment for chronic hemorrhoids. However, both open and closed hemorrhoidectomy have their disadvantages. Purpose. To study the effectiveness of various surgical treatments for patients with chronic hemorrhoids using a laser coagulator. Materials and methods. We conducted a clinical examination and treatment of 140 patients with chronic grade III-IV hemorrhoids by Goligher. All patients were presentably divided into three groups. The first group included 60 patients who had classic open hemorrhoidectomy - the Milligan-Morgan operation. The second group included 40 patients in whom had surgical treatment with a laser coagulator - laser open hemorrhoidectomy. The third group consisted of 40 patients who underwent laser open hemorrhoidectomy, supplemented with laser transcutaneous submucosal mucopexia. Results and discussion. Analyzing the indicators of pain in different groups of patients at different postoperative period, we found that on the first postoperative day the classic Milligan-Morgan surgery, the was most uncomfortable procedure (the first group of patients). Among the patients in the second and third groups there were no people who rated pain above 7 points. In the first group, the median period of first defecation was in 5.0 days. As for in patients of the second group, the first defecation was observed in terms of the 3-5 days with a median of 4.0 days. A similar indicator was observed in patients of the third group. Patients in the second and third groups did not indicate severe pain during the first act of defecation. The anal hematoma was found only in patients of the first group (p<0.01). Anal infiltration occurred in 12.5±5.23 % in the third group (p<0.01). Infections of wounds were not found in any group. Conclusion. Laser open hemorrhoidectomy is an effective method of surgical treatment of patients with chronic hemorrhoids. However, like the classic open hemorrhoidectomy Milligan-Morgan, it allows to eliminate only pathological substrate (cavernous bodies). To prevent recurrence of the disease, it should be supplemented with laser transcutaneous submucosal mucopexia. Analysis of cases of early postoperative complications showed that the classic Milligan-Morgan hemorrhoidectomy, compared with intraoperative laser coagulation, had a significantly higher frequency (p<0.001).
The most important factors in the development of chronic haemorrhoids today are considered to be the combination of two factors (vascular and mechanical) that lead to the development of hemorrhoids. The underlying vascular factor is the vascular dysfunction, providing arterial blood flow through the arteries to the cavernous bodies and outflow through the cavernous veins, which leads to dilation of cavernous bodies and the formation of vascular malformations.There were performed clinical examination and treatment of 140 patients with chronic hemorrhoids of stage III-IV according to Goligher. The features of arterial blood supply of the anal canal were evaluated by transrectal ultrasound examination.It was found that there was no clear linear relationship between the number of anal arteries with increased blood flow and the number of hemorrhoidal nodes in the patient. Each node was supplied with blood from one or two arteries: the node placed at 11 o'clock had blood supply from the arteries visualized at 10 and 11 o'clock, the node at 3 o'clock - arteries at 3 and 5 o'clock, the node at 7 o'clock - arteries at 7 and 9 o'clock. The arteries were most frequently visualized at the first (89.4%), the third (93.3%), the seventh (88.8%) and the eleventh (93.4%) hours. With less frequency the hemodynamically significant arteries were visualized at the fifth (65.0%), the ninth (62.8%) and the tenth (66.7%) hours. The arteries that were suppliing blood hemorrhoidal vessels were located in the internal sphincter at a depth of 5 to 10 mm. In the area of 3, 7 and 11 hours, they overlapped with a mosaic pattern that corresponded to the localization of the cavernous body and resembled an arteriovenous fistula according to the СDS.
