What is syringomyelia? Syringomyelia is the accumulation of fluid in the scrotum caused by excessive secretion or absorption of the sphincter. Inflammation, trauma, tumors and other scrotal and testicular pathologies can cause syringomyelia. It is generally classified as testicular syringomyelia, testicular and spermatic syringomyelia (i.e. infantile type), traffic syringomyelia (i.e. congenital syringomyelia) and spermatic syringomyelia. Diagnostic points of syringomyelia: 1. There may be a round or oval soft syringomyelia swelling on the affected scrotum or spermatic cord. 2, clinical symptoms are not significant, occasionally there is swelling and pulling discomfort, when obviously enlarged or can affect urination. 3. Positive transillumination test of the swelling. 4.B ultrasound examination can clarify the diagnosis. Causes of syringomyelia 1. It has not been fully clarified, and may be caused by a variety of reasons leading to increased secretion and decreased absorption of the sphincter; 2. Primary diseases, such as acute and chronic orchitis, epididymitis, spermatorrhea, etc., which stimulate increased exudation of the sphincter and cause fluid accumulation. Or tuberculosis and tumor exudation of the testes and epididymis themselves cause effusion; 3. congenital factors, such as defects in the lymphatic duct system of the sphincter cavity; 4. surgical injury to the scrotum or lymphatic reflux obstruction caused by filariasis and schistosomiasis; surgical methods for syringomyelia 1. traffic syringomyelia, the surgical method is similar to that of inguinal hernia surgery. In addition to excision of the sphincter, the sphincter duct communicating with the abdominal cavity must be ligated at the internal inguinal ring and done in high suspension. 2.Sphincter reversal is the most commonly used surgical method. For larger syringomyelia, most of the sphincter is removed and then turned to the posterior side of the testis and spermatic cord, and the plasma membrane of the sphincter is sutured outward. The suture should not be too tight when closing the sheath of the spermatic cord, so as not to impede blood circulation and testicular atrophy. 3.Sphincter partial excision is suitable for smaller spermatic cord syringomyelia, middle-aged and older patients with larger syringomyelia and patients with serious adhesions around the syringomyelia that cannot be easily separated in a large area. After excision of the anterior wall of the cyst, the sphincter is sutured tightly to the endothelial layer to prevent bleeding and recurrence of adhesions. 4.Sphincterotomy is also commonly used for spermatic sphincter effusion. The sphincter of the effusion is carefully separated from the spermatic cord and excised completely.
