Transanal Surgery is nerve-racking enough, so being able to undergo a minimally invasive surgery makes it all better. The anus is susceptible to many types of diseases like cancer, polyps, ulcers, and abscess. Whenever these things are discovered in the anal cavity or rectum, it is important for them to be removed as quickly as possible. Transanal Surgery is typically used to treat polyps and tumors. There are limits to minimally invasive transanal surgery. If polyps or tumors are too far into the colon, minimally invasive transanal surgery is not possible. Early diagnosis of these things gives you a better prognosis and makes you an eligible candidate for transanal minimally invasive surgery.
The lower end of the digestive tract includes the rectum and anus. Rectal and anal cancer are very common. Rectal cancer is the third most common form of cancer in humans. The sigmoid colon is attached to the rectum, but diseases in this area are not always treatable by minimally invasive transanal surgery. The procedure is minimally invasive because there are no incisions made externally to the body. The instruments used, go through the anus. The problem with using this surgery for the colon is that the instruments are not flexible and cannot bend to take care of polyps and tumors in the colon.
There are two types of transanal minimally invasive surgery. The first type of minimally invasive surgery is called local transanal resection. Minimally invasive transanal surgery requires the use of an endoscope. The surgery does not require any external incisions. The endoscope is placed inside the anal cavity. The instrument cuts away layers in the rectal wall to remove polyps and tumors. The procedure only requires local anesthesia. This procedure gets polyps in the rectum and anus. Polyps any further than that cannot be taken care of by this type of surgery. This surgery can also be done laparoscopically. The surgery would require only small incisions in the abdominal wall. Small instruments go through the cut, and the surgery is performed relatively quickly.
Transanal endoscopic microsurgery is the second type of minimally invasive surgery. This procedure is common for early stage rectal cancer. This procedure can treat polyps and tumors further into the rectal cavity. This surgery is also endoscopic. You do not have to make any incisions to the outside of the abdomen. The procedure begins with the use of a magnifying scope. The scope is inserted into the rectum. This helps the surgeon see inside the rectal cavity. Not everyone can perform this surgery because it takes special expertise. The surgery is great because it is rare that there is a recurrence of tumors and polyps after surgery is completed. After the scope is inserted, the doctor then places in a port. The port gives access to laparoscopic tools. This procedure is extremely beneficial because of its accuracy, During surgery, the doctor also preserves the sphincter muscles. There is no risk of injuring those muscles. This surgery is not as popular because it requires a lot of skills and training. Many doctors are aware of the surgery, but they do not have the training to perform it.
There are many benefits to transanal minimally invasive surgery. The biggest benefit is the use of robots versus having to use a human hand. This type of surgery is considered minimally invasive because it does not require a large incision at all. Matter of fact, the surgery does not require any incisions to the outside of the body. The only cuts being made are on the inside, in the wall of the rectum. Laparoscopic surgery requires small incisions, but the recovery process is still very short. Minimally invasive surgery also takes less time. When surgery is short, you also have less bleeding. The interesting thing about local transanal resection is that you do not even have to be put to sleep. This cuts down the risk of reactions to anesthesia. After surgery, there is very little pain. You do not have to worry about large scars healing. The recovery is much quicker. With less pain, you will not have to use as many pain meds. Shorter hospital stays is always a plus. When you stay in the hospital for shorter periods of time, you decrease the risk of having hospital-acquired infections.
Transanal minimally invasive surgery is a great technique for removal of rectal polyps and tumors. The surgery has its limitations in that it cannot treat problems further into the colon, but there are other methods of surgery for that. It also cannot treat polyps and tumors that are too big. The tools are fairly small, so it is necessary for the polyps and tumors to be small as well. When polyps and rectal cancer are diagnosed early, the doctor can treat them by transanal minimally invasive surgery. It is important to keep up with your yearly physicals. Getting an early diagnosis can be the difference between you having transanal minimally invasive surgery and you needing surgery that opens the whole stomach cavity.
