Liver cysts larger than 5 cm are mainly treated by cyst “windowing” (also known as cyst “debridement” or cyst “debridement and decompression”), and in some cases, partial hepatectomy. Most of these procedures are now performed laparoscopically. Liver cysts are a common benign disease of the liver. When the cysts grow to a certain size, they can compress the surrounding organs and cause symptoms such as abdominal distension, nausea, vomiting and abdominal pain. Ultrasound is the first choice for diagnosis. For liver cysts larger than 5cm, cyst “windowing” (also known as cyst “decapitation” or cyst “decapitation and decompression”) can be performed after symptoms appear. Some patients who are suitable for resection may also undergo partial hepatectomy. If there is a complication of infection or bleeding, a drain may be placed after the operation and removed when the drainage fluid becomes clear. Suffering from liver cysts, you should seek medical treatment in time and under the guidance of the doctor, do not take medication without authorization, so as not to delay the condition. Pay attention to rest on weekdays, avoid overwork, and maintain a regular routine.
