What Is a TME Surgery?

Total mesorectal excision (TME) is a surgical procedure to remove cancer from the end of the anal area (rectum).

Total mesorectal excision (TME)is a type of procedure to removecancerfrom the end of the anal area (rectum). In this procedure, the surgeon removes the part of the rectum that containscancerand some healthy tissue on either side.

They also remove the fatty tissue (mesorectum) around the rectum, which contains the blood vessels andlymph nodes. Removing the mesorectum reduces the risk of anycancerbeing left behind. This procedure can sometimes be used for early-stagecancers更高的直肠和无法访问by other procedures.

A specially designed magnifying scope is inserted through the anus and into the rectum. This allows the surgeon to remove the cancerous part with greater precision and accuracy.

Total mesorectal excision (TME) surgeryis recommended for patients who have cancers in the middle and lower area of the rectum. It is now considered the gold standard procedure for removing tumors in the middle and lower areas of the rectum.

Total mesorectal excision (TME)is performed under general anesthesia with or without an epidural painkiller. The procedure is performed by a specially designed instrument called a laparoscope.

直肠和结肠释放的年代urrounding attachments so that the diseased segment can be safely removed along with some of the fatty tissue that carries the blood vessels and lymph drainage to the bowel.

The ends of the intestine are then reattached. At the end of the operation, the abdominal wall is stitched up and then the skin is closed, usually with absorbablesutures.

The rectal procedure has three different methods of approach:

• Anterior resection or TME:Anterior resection is usually used for cancers in the upper and middle parts of the rectum (close to the colon). After the cancer is removed from the area, the surgeon rejoins the two open ends of the intestine. Some people may need an artificial opening called astomaafter this operation. This artificial opening is usually closed after a few months.
• Colo-anal and J pouch surgery:This method may be used for removing cancers in the lower rectum. The surgeon removes the entire rectum and attaches the intestine to the anus. Sometimes, the surgeon makes a pouch (called a J pouch) from part of the colon, before joining it to the anus. The pouch acts like a new rectum and stores stools until it is convenient to pass them. Usually, the patients need an artificial opening for this procedure, which is later closed upon the patient’s recovery.
• Abdominoperineal resection (APR):This method is usually used for cancers that are very low in the rectum (near to the anus). To remove all cancers, the surgeon needs to remove the rectum and anus. The patient might have a permanent artificial opening for this procedure because the anal area is completely removed.

Total mesorectal excision (TME) procedureis associated with the following risks:

• Anesthesia complications such asheadache, drowsiness, andvomiting
• Bleeding
• Pain
• Infection in the surgical area
• Leak from the joined area
• Blood clotin the veins orlungs
• Impaired rectum function
• Stigma due to the presence of an artificial opening

Patients who haverectal cancerthat is confined to the lower two-third of the rectum are generally considered good candidates for a total mesorectal excision (TME) surgery. Patients are usually discharged within a week after the procedure. Patients typically have a five-year survival rate with fewer complications after a TME procedure.

Complete mesocolic excision (CME)is the surgical treatment of colon (large intestine) cancer. The goal of this procedure is to remove the affected large intestine along with some healthy tissue on either side.

通常,医生也消除了脂肪组织(mesocolon) around the colon, which contains the blood vessels and lymph nodes. Removing the mesocolon reduces the risk of any cancer being left behind.

This procedure is performed under a specially designed laparoscope under general anesthesia. CME adopts the same principle as total mesorectal excision (TME).
