Imaging examination: Yang (1993) 17 cases were clinically suspected of anorectal abscess or fistula, 6 cases were clinically suspected of abscess, and anus ultrasound AUS examination also showed abscess; In addition, 82%(9/ 1 1) AUS found fistula, but routine clinical examination failed to find it.
By comparing AUS with magnetic resonance imaging, it is considered that the former is sometimes valuable in the diagnosis of interssphincter fistula, but not in the diagnosis of external sphincter fistula and trans-sphincter fistula, while the latter has absolute superiority and accuracy in the diagnosis of complex high anal fistula, horseshoe anal fistula and difficult cases that are difficult to diagnose in clinic.
Follow the doctor's advice, pay attention to diet and anti-inflammatory treatment after operation, and leave the hospital at least ten days later. Of course, I suggest going to the hospital for consultation, hoping to help you. It is suggested that in life, pay attention to diet, drink plenty of water, eat more fruits and vegetables in diet, and keep the stool unobstructed.
Routine examination before operation, such as ECG chest film, blood test, etc. The cost depends on what level of hospital you go to for surgery. Big hospitals and provincial hospitals are expensive, but also depends on what anesthesia you use during the operation, the waist anesthesia is much more expensive, and your recovery after the operation.
After anorectal surgery, you must follow the doctor's arrangement, clean the anus after defecation to prevent the bridge from healing again, and eat more fruits and vegetables, drink more water, keep the stool unobstructed and eat more high-protein food after surgery, which is conducive to wound recovery.
