The liver is the largest solid organ in the body. It is located in the right upper part of the
abdominal cavity, below the breathing muscle (diaphragm), and behind the rib cage. It is
surrounded by multiple vital organs, the stomach lies on its left, the gallbladder sits just
below the edge of the liver, and the small and large intestines travel along its lower
border. The liver is made of two parts, a bigger right lobe and a smaller left lobe. The
liver is connected to the intestines through a conduit called the common bile duct. The
gallbladder that has a function of storing bile is also connected to the common bile duct
via the cystic duct.
The liver is responsible for a plethora of vital functions, including but not limited to detoxification of body wastes, production of essential nutrients for body function, it produces bile that helps with fat digestion, it has a very important role in immunity, and it produces clotting factors to prevent bleeding.
The liver is the only visceral organ that has the ability to regenerate. After liver surgery the remaining liver portion will grow in volume as to assume the function of the liver portion that was surgically removed. In healthy livers, we only need 20-25% of our liver to survive, that means that, if needed, a 75-80% of the liver can be surgically resected. That is not the case in livers that diseased, as in fatty liver and livers of cirrhotic patients per example, in which cases about 30-50% of the liver is needed for survival.
The liver get its blood supply though two sources: the hepatic artery and the portal vein.
Blood after circulating through the substance of the liver and detoxified, drains into
hepatic veins that direct blood back to the heart. These blood vessels and bile ducts
divide into smaller branches that supply individual segments of the liver. There are 8
segments in a human liver.
Liver surgery is mainly based on this internal liver anatomy. The aim of surgery is the remove as little liver substance as possible and maintaining adequate blood supply and adequate drainage of the remaining portion of liver.
Liver diseases vary between benign diseases and cancerous diseases. Common symptoms depend on the nature of the problem but in general include:
Liver diseases that are treated with surgery are usually tumors or masses/cysts. The are divided into three categories:
The extent of surgery of the liver is dictated by the location of the disease, whether
benign, malignant or pre-malignant,. Liver surgery is one of the biggest and most
involving surgeries in the abdomen, and that is due to the proximity of the liver to vital
organs, in addition to important blood vessels.
The aim of liver is to remove the diseased fragment of the liver, and leave behind a healthy, disease-free liver portion with adequate blood supply through conservation of arteries, veins, and bile ducts, supplying and draining that remaining part.
Surgery of the liver includes working around large blood vessels, adding to the risk of the surgery. Bleeding is always a concern in large liver surgeries where a big portion of the liver needs to be excised. Removing the right lobe of the liver is called Right Hepatectomy, and removing the left lobe of the liver is called Left Hepatectomy. Removal of part of a liver love is called Partial Hepatectomy.
In certain tumors of the liver, the current approach is to burn the liver lesion in place instead of surgically removing it. This is a novel approach for selected liver tumors that we use nowadays, to spare some patient the morbidity and the complications of large liver resections. Liver ablation is done on patients that cannot tolerate and will not survive a major liver resection, or in some tumors that are very small and be ablated achieving similar results to liver resection. This procedure can be done through small band-aid type incisions where a camera is inserted into the belly and an ultrasound probe is used to locate the tumor in the substance of the liver, then a thin microwave antenna is inserted through the skin to target that lesion and burn it in place using microwave technology. This is a very safe and effective procedure when indicated. Patients will be discharged home the same day, or will spend one night in the hospital at the most.
You just had liver ablation surgery and completed your hospital stay after the procedure. It is now safe to be discharged home. Your surgeon will be keeping a close eye on your progress even if are at home. Healing from a liver ablation surgery usually takes a few days.
We encourage resuming walking and light activity immediately; as soon as you are sure
you are not going to have issues with dizziness or lightheadedness. You may resume
driving when it is comfortable to walk up and down stairs. Don’t plan on any strenuous
activities, like sports or going to the gym, until your postop appointment. Your surgeon
may have specific instructions to add to this; usually these are outlined to you before
surgery. The bottom line: if it hurts, don’t do it!
Driving should not be attempted until you are off pain medications and able to go up and down stairs comfortably. You should be able to slam on the brakes to avoid an accident without causing any pain.
The basic rule is take in what your body is telling you. It takes about a week at least after liver surgery in order to resume a regular diet. Your stomach will be slow at digesting food especially after a large liver resection, certainly faster with laparoscopic or robotic surgery. Some find it easier to digest bland foods, light foods, or predominantly liquids. Make sure you stay hydrated, and avoid excessive caffeine. Also, no alcohol if you are taking prescription pain medications. We strongly recommend being on supplements like Ensure or Boost after surgery for a few weeks.
Constipation is very common after surgery. We recommend staying well hydrated, and using Miralax, prune juice, or Milk of Magnesia for a few days until things are back to normal. Do not let more than 48 hours go by without a bowel movement without starting the above medications. If they fail to help within another 24 hours, call our office. Diarrhea is common if you are taking antibiotics. If you have this problem, we would suggest either probiotics while you are on the antibiotics, or eating yogurt with active cultures. If diarrhea occurs more than 4-6 times daily for more than 48 hours, call us. Make sure your doctor is aware of any chronic difficulties with urination (like prostate trouble) before surgery.
Usually surgical wounds will have either glue or steri-strips (butterfly tapes) on them, often covered with gauze. Glue, steri-strips, or waterproof plastic dressings can all get wet the day after surgery (unless your surgeon advises differently). Wounds with visible staples or sutures can get wet in the shower after 48 hours. Do not submerge your wound (tub bathing or swimming) for one week. If you have a feeding tube, do not submerge in water until this tube is removed. If you have a surgical drain, do not submerge in water until that drain is removed. While soap will not harm the wound, do not scrub it. Do not apply peroxide or other chemicals unless you have been told to do so by your doctor. After 48 hours, change or remove gauze dressings or Bandaids. Do not leave soiled or wet dressings on the wound beyond 48 hours. Most wounds can then remain uncovered, unless you have been told otherwise. Light gauze covering to prevent chafing is acceptable if you wish. You may notice a slight drainage (usually pink or reddish in color) from the incision site. This is normal and not a cause for concern. Light pinkness immediately surrounding the incision, and not spreading over time, is normal. Bruising is common and may extend for up to an inch. Spreading redness, progressive swelling with bruising, and malodorous drainage are not normal and should prompt a call to our office.
If you are sent home with surgical drains, you will likely be given instructions at the time
of discharge for care of them, and a log sheet to record the output. It is important to
note the daily output of the drain(s) so we will know when to remove them. Drains that
empty into a suction bulb or attached bag can get wet in the shower. If there is gapping
of the skin around the drain. Do not submerge the drain site underwater, such as tub
bathing or swimming. Slight pinkish or yellowish drainage from around the tube is
normal while it is in place, as is a small amount of redness at the site. Gauze over the
site may help protect your clothing from staining. Foul smelling or copious drainage
around the drain, or spreading redness around the drain, is not normal and should
prompt a call to our office. If the drain reservoir fails to hold suction when you squeeze
it, or if the drainage suddenly drops to near zero, call our office.
Normal care of drains includes emptying the fluid in the reservoir every 8 hours and recording the amount per 24 hour period. Bring this record to your postoperative appointment. The fluid may need to be emptied more frequently if the drainage is heavy. Fluid will often be red at first, then pink, then yellow as the wound heals. Stringy material in the tubing or reservoir is normal.
Prescription pain medications are there to help you recover comfortably, but stop them as soon as you are able. Side effects of nausea, vomiting, dizziness, fatigue, poor appetite, and above all constipation, are common. If you have these issues, try to use ibuprofen and Tylenol instead (see below). Do not use alcohol or drive if you are taking prescription pain medications. Unless you are told differently by your surgeon or primary doctor, you can take 400 mg ibuprofen every 4-6 hours, or 800 mg every 8 hours, for the first 3-5 days after surgery, for a maximum dose of about 2400 mg/day (refer to the label for specific dosing based on age and weight). It is best if you can take some food with this medication. Tylenol is also acceptable in small liver surgeries, however should be avoided in large liver surgeries, or if you have cirrhosis. Blood thinners should only be restarted after surgery according to the plan discussed with you by your surgeon or prescribing doctor before surgery. If this was not made clear to you, call our office. All other medications should be resumed once you get home. Vitamins and supplements are not necessary to help you heal, unless you have a known deficiency. You may resume them after you get home if you wish. We would suggest sleep aids not be used while you are on narcotic pain medications.
