Some issues Dr. Isabel Carlton Clark, MD can help you with:

Biopsy

A biopsy is a procedure performed to remove a small sample of cells for testing. The cells are examined in a laboratory to check for disease, or sometimes to see how badly a known disease is affecting them. Biopsy can be performed on any part of the body.

Although biopsy is most often associated with cancer, it can also be used to check for other diseases, such as infections. A biopsy sample can be scraped, cut, collected with a needle, taken with a machine that punches out a tiny piece, or removed with the tiny tools in an endoscope.

In most cases, a biopsy is a simple outpatient procedure. Depending on the procedure, patients may need to stop taking certain medications beforehand, such as blood thinners. It is important for patients to tell doctors if they are pregnant, as certain biopsies require the use of x-rays to guide the needle to the right location. There is usually very little pain associated with a biopsy. Patients will have to wait a few days to hear the results.

Breast Biopsy

Breast biopsy is a procedure where a small sample of tissue is collected from the breast for testing. A physician may prescribe a breast biopsy for a variety of reasons, but they are most frequently prescribed for a lump found in the breast. Biopsy samples extracted are examined by pathologists in a laboratory setting and are tested to determine if they are cancerous or benign, or indicative of some other condition. Depending on the lab results, physicians may prescribe additional treatment. Other circumstances which may prompt a breast biopsy include:

  • Mammograms that detect other unusual features in the chest, such as a cyst or calcium deposit
  • Breast scans or ultrasounds that display abnormalities
  • Nipple changes, such as scaling, crusting, or bloody discharge

Breast biopsies are collected through several different procedures and the specific type of biopsy that a patient receives depends on the size, location, and features of a breast lump or irregularity. The three main methods of collecting a breast biopsy include:

  • Fine needle aspiration (FNA biopsy), where a thin needle is directed into a breast lump or abnormality, extracting a small sample of tissue or liquid
  • Core needle biopsy (CNB biopsy), where a hollow needle is directed into a breast lump or abnormality, extracting cylinders of tissue called "cores"
  • Open (surgical) biopsy, where a breast lump is removed through an incision in the breast

Fine needle aspiration (FNA) and core needle biopsy (CNB) are sometimes image-guided, where a mammogram, ultrasound, or MRI helps direct the physician performing the needle extraction.

Fine needle aspiration, the most common biopsy method, generally requires few patient preparations. It is recommended patients avoid using lotion, deodorant, and perfume prior to their biopsy procedure. FNA biopsy is performed with local anesthesia (topical numbing cream) and typically has a quick recovery, but patients may experience soreness for a few days. Core needle biopsy extracts slightly more tissue than an FNA biopsy.

Open (surgical) biopsy is more invasive and requires general anesthesia, where patients are put to sleep during the procedure. Patients must fast prior to the surgery. After the biopsy is performed, patients are monitored in a recovery room for a time before being discharged, when they will need someone else to provide transportation.

Although some may consider breast biopsy to be a simple procedure, it can catch critical issues - particularly breast cancer - that impact wellness. If a breast biopsy reveals an underlying condition like life-threatening cancer, patients can receive the diagnosis and medical treatment that is necessary for their long-term health.

Pancreatectomy (Pancreas Removal)

Pancreatectomy is surgery to remove part or all of the pancreas to treat pancreatitis, tumors, or cancer. The pancreas is located behind the stomach and near the small intestine and spleen. There are three sections of the pancreas:

  • The head, which is the portion closest to the intestines
  • The body, which is the middle portion of the pancreas
  • The tail, which is the portion nearest the spleen

Pancreas removal procedures differ based on how much of the pancreas and surrounding organs are removed. There are three types of pancreatectomy:

  • Distal pancreatectomy removes the tail and body of the pancreas. This procedure treats tumors confined to these areas.
  • Pancreaticoduodenectomy, or the Whipple procedure, removes the pancreas, duodenum, bile duct, and, sometimes, part of the stomach. The Whipple procedure is used for pancreatic tumors that have not spread past the head of the pancreas and for other conditions affecting the pancreas, duodenum, and bile duct.
  • Total pancreatectomy removes the whole pancreas along with the duodenum, gallbladder, parts of the stomach and bile duct, surrounding lymph nodes, and, potentially, the spleen. Rarely performed, total pancreatectomy treats conditions that involve the entire pancreas, such as tumors found in multiple sites on the pancreas, or for rare tumors such as intraductal papillary mucinous neoplasms (IPMN).

Pancreatectomy can be done by open or minimally invasive surgery. During a laparoscopic pancreatectomy, the surgeon will use tiny incisions to insert a thin tube with a camera, or laparoscope, into the abdomen. Open surgery, or a laparotomy, is performed through a larger incision on the abdomen. If additional organs are removed, some procedures may require that the small intestine be reconnected to the stomach.

The hospital for pancreatectomy stay may be between 1-3 weeks. Generally, laparoscopic surgeries require shorter recovery periods. Whether patients undergo an open or laparoscopic procedure is determined by factors such as their condition and the extent of their procedure. For example, open surgery tends to be more common for distal pancreatectomies. If patients have difficulty eating, they may require a nasogastric tube, inserted through the nose, to carry food to their stomachs. A catheter can be inserted into the bladder if patients have trouble urinating. Full recovery may take about two months.
