Some issues Dr. Michael Kevin O'Brien, MD, FACS, PhD 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.

Laparoscopic Surgery

Laparoscopic surgery is a kind of minimally invasive surgery using a thin, narrow tube called a laparoscope. Usually performed on the abdomen or the pelvic region, the surgeon makes a few very small incisions instead of one large one.

During the procedure, the surgeon inserts the laparoscope, which contains a light and camera that allows the surgeon to see what is happening inside the body. Then tiny tools are placed through the small openings and used to perform the surgery.

The most common laparoscopic surgery is gallbladder removal, but laparoscopic surgery may also be used for the removal of a kidney or appendix, to treat certain cysts and tumors, for bariatric surgery, for some GERD treatments, or for hernia repairs, among others.

Because laparoscopic surgery only uses a few tiny incisions, the scars are minimal and recovery is easier than with open surgery.

Peritoneal Dialysis

Peritoneal dialysis is a procedure that imitates renal (kidney) function by filtering patients' blood. When the kidneys do not work properly, waste can accumulate in the blood and unbalanced chemicals can impair the body's critical functions. In order to stay healthy, a person without proper kidney function must receive dialysis. There are two forms of dialysis treatment: hemodialysis and peritoneal dialysis. Both forms of dialysis are recurring treatments that in many cases last throughout the lifetime of the affected patient.

Peritoneal dialysis can be performed at home by oneself after an initial surgery. To start, a physician (generally a surgeon) will make a small incision in the lower abdomen and insert and surgically attach a catheter (thin tube). At home, the patient connects a pump to the abdomen catheter, delivering dialysate (dialysis fluid) from a bag hanging on a wheeled stand. This fluid enters the peritoneal cavity (greater abdomen area containing the stomach, liver, and intestines) and collects waste through osmosis, where waste in the blood moves across a membrane and into the dialysate. This process continues for several hours until the fluid concentration is equal between the blood and dialysate, at which point the fluid can be drained. The fluid can then be passed through a machine called a cycler, which removes waste and allows for the dialysate to be reused. This process is repeated about four times per day. Dialysis patients must limit the amount of fluid they consume prior to receiving dialysis and should also avoid eating salty foods. The cycler cannot filter more than a certain amount of waste products from the blood.

Kidneys are important organs, and peritoneal dialysis can be vital for those with renal dysfunction. Peritoneal dialysis may be a more convenient alternative to hemodialysis, which requires going into a clinic.
