Some issues Dr. Christine J. Ren-Fielding, MD can help you with:

Gallbladder Removal Surgery (Cholecystectomy)

The gallbladder is a small, pear-shaped organ on the right side of the upper abdomen, underneath the liver. Its purpose is to store bile, which is used to digest fat. Occasionally, the gallbladder can develop mineral stones, called gallstones. If they are large enough, gallstones can block the ducts in the gallbladder and cause swelling and infection. Gallstones can be treated with lifestyle changes and medication, but sometimes this is not enough. In these cases, it is best to remove the gallbladder before it can cause more serious problems. The surgical removal of the gallbladder is called a cholecystectomy.

Today, most gallbladder surgeries are done laparoscopically. Four tiny incisions are made in the abdomen, and small tools are inserted through these tiny incisions to perform the surgery. Because the incisions are much smaller, recovery time is much faster with this type of surgery. Patients are usually discharged from the hospital the same day. Sometimes, open surgery is used to remove a gallbladder. In this type of surgery, a cut about six inches long is made in the upper right abdomen. After the gallbladder is removed, it is sutured or stapled closed. With open surgery, patients usually stay in the hospital for two to three days to recover before they are discharged.

Gallbladder removal, like any surgery, carries some risks, such as bleeding, infection, or the development of blood clots. Doctors will tell patients how to minimize their risk for complications. After surgery, patients are advised to avoid strenuous activity for several days. They should not soak in a bath until their sutures or staples have been removed. Patients should wash hands before touching the area around the incision. It will take a couple of days until patients feel like themselves again and a few weeks until their scar has healed and faded.

Gastric Bypass Surgery

Gastric bypass surgery is a procedure that promotes weight loss by reducing the stomach and altering how the digestive system absorbs and processes food. The procedure treats morbid obesity, where one's weight impairs day-to-day function or poses serious health risks. Gastric bypass surgery is used only after other weight loss treatments are unsuccessful.

Generally, gastric bypass surgery is performed on patients who have a BMI of 40 or greater, or a BMI of 35 or greater with a weight-related health condition such as type 2 diabetes. Bariatric surgeons frequently expect patients to first attempt natural weight loss for about six months to prove to the surgeon that the patient is capable of maintaining a post-surgery diet and exercise regimen.

For obese patients, gastric bypass surgery has many potential health and weight benefits. Gastric bypass surgery restricts the amount of food the stomach contains, as well as:

Reduces the calories the stomach absorbs
Alters gastrointestinal hormones, which help to heal obesity-induced metabolic syndrome
Suppresses appetite
Alleviates conditions caused or exacerbated by obesity, such as obstructive sleep apnea, heart disease, and type 2 diabetes
Contributes to mental health by improving self-esteem

During gastric bypass surgery, the stomach is stapled to reduce its size, and a small hole is created in the stomach and attached to the middle section of the small intestine. This direct connection between the stomach and the middle of the small intestine creates a channel for some food to bypass the normal route. By bypassing the upper small intestine and larger region of the stomach, food is not fully absorbed and patients do not retain the same amount of calories as before. This procedure is also sometimes referred to as "Roux-en-Y" gastric bypass surgery. Some bariatric surgeons may perform a "laparoscopic bypass" which uses a tiny camera (laparoscope) to guide the procedure.

Gastric bypass surgery is performed with general anesthesia and as preparation, a liquid diet is required for two weeks prior to undergoing the surgery. After the surgery, patients will spend about two days in the hospital and may miss work for two to three weeks. In the first month after the surgery, patients are only able to consume small portions of liquid or soft food. Even after reintroducing solid food, patients feel full quickly, sometimes after eating just two or three tablespoons. Some patients experience "dumping syndrome" (rapid processing of food into the small intestine), which is common during the recovery process. Gastric bypass surgery patients must also make permanent lifestyle changes. For example, gastric bypass patients are required to take vitamins for life after surgery and required to forever avoid certain foods, such as alcohol, sugar, and high fat food.

While the gastric bypass recovery process can be challenging, surgery results are usually swift: most gastric bypass surgery patients lose nearly half to two thirds of their starting weight within two years of surgery.

Robotic Surgery

Robotic surgery is a type of minimally invasive surgery, using a tiny opening to get inside the body instead of making a large cut. It uses small tools attached to a thin robotic arm, which is controlled by the surgeon. Robotic surgery may be referred to by the specific kind of robot that is used. The most advanced robot currently in use is called the da Vinci, and surgery using it is sometimes called da Vinci surgery.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.
