Hernias Often Need Surgery To Correct

Dear Doctor: If you’ve got an abdominal hernia and it doesn’t bother you, can you just leave it alone? How is it treated? I’ve read about using mesh, but apparently some of them have turned out to be defective.

Dear Reader: The muscles that surround the abdominal cavity play a number of important roles. They support upright posture and controlled movement; aid in breathing; and play a role in urination, bowel movements, coughing, singing, vomiting and childbirth. They also keep the abdominal organs, tissues and intestines safely in place. When these muscles develop an opening that allows fatty tissue or a portion of the intestine to protrude, it’s known as a hernia. Although the majority of hernias develop in the abdominal area, they can also occur in the region of the groin and the upper thigh.

Abdominal hernias are common. They can occur in anyone, including babies, children and women, but are most often seen in men over the age of 40. When a hernia develops, you will notice a swelling or lump that is present when you’re standing up or using your abdominal muscles. The swelling will often vanish when you lie down. The condition is usually pain-free in its early stages. Some people report feeling pressure, or a tugging sensation, at the site of the hernia. None of the different types of hernia will heal on its own.

When a hernia is small and painless, some doctors recommend watchful waiting, perhaps with the use of supportive garments. But studies have shown that when left untreated, a hernia will often continue to grow in size and eventually begin to cause pain. In the most severe cases, a hernia can become strangulated. This occurs when the surrounding muscle contracts and cuts off the blood supply to the protruding tissue. That means that a portion of intestines inside the body are also starved of blood. Symptoms of a strangulated hernia include sudden and severe pain, bloody stool, fever, nausea and vomiting, inability to pass gas, constipation and exhaustion. A strangulated hernia is a serious and life-threatening condition that requires immediate medical treatment.

Hernias that grow larger over time or begin to cause pain require surgical repair. The procedure involves first returning the displaced tissues to their proper place in the abdomen, and then repairing the gap in the muscles. This is done by either sewing a patch of surgical mesh over the weakened area or with stitches.

The procedure can be a laparoscopic surgery, which is a minimally invasive technique performed through tiny incisions in the abdomen, or via open surgery. This involves the same series of repairs, but through a larger incision. In most cases, a hernia repair is an outpatient procedure and doesn’t require an overnight hospital stay.

Hernias have a high rate of recurrence, and surgical mesh is most effective at strengthening the weakened area. And, while it’s true that some brands of surgical mesh have been subject to recalls, those products are no longer on the market. Be sure to share your concerns with your surgeon, who will help you choose the best treatment for your specific situation.

Radiation Therapy Can Cause Damage to Surrounding Tissues

Dear Doctor: A close relative had extensive radiation therapy for an early breast cancer. The treatment was effective, but it damaged the surrounding tissues, including her aortic valve. What are the potential side effects of radiation therapy?

Dear Reader: Radiation therapy, also known as radiotherapy, is a type of cancer treatment that uses intense beams of energy to kill cancer cells. Most often, it uses X-rays, a type of electromagnetic radiation, but a newer type of therapy uses protons. These are subatomic particles that carry a positive charge. Although both approaches to radiation therapy are effective at killing cancer cells, each can cause a range of side effects. These vary from person to person and depend not only on the type and location of a person’s cancer, but also on their general health as well.

Unlike chemotherapy, which is systemic, radiation therapy is a highly localized treatment. A person’s tumor is mapped, and the beams of energy are precisely focused on the area. Even so, surrounding healthy tissues are often damaged. Due to the physical properties of protons, that type of radiotherapy can be successful at sparing surrounding tissues. However, proton therapy isn’t widely available and can’t be used for all cancers. Radiation therapy with X-rays, while successful at killing cancer cells, can also cause damage to healthy tissues.

Radiation therapy sessions last about 15 minutes and are not painful. Treatment is administered five days a week and lasts from three to nine weeks, depending on the cancer. The energy used to kill the cancer cells is quite powerful and, over time, the nearby healthy tissues tend to sustain damage. This results in a range of side effects. A common one is fatigue, which begins during the course of treatment and can persist for several weeks or months after treatment has ended. Many people develop skin problems such as dryness, itching, blistering or peeling in the site where the radiation is delivered. Depending on the part of the body receiving the treatment, additional side effects can include swelling, or edema; hair loss; nausea; trouble swallowing; diarrhea; problems with urination; or changes to taste.

When heart muscle is exposed to radiation therapy, as happens in treatment for breast cancer, Hodgkin lymphoma and cancers of the lung or esophagus, injuries can occur. These can include the heart valve injury that your relative experienced, as well damage to the coronary arteries, the tissues that cover the heart, the specialized cells that control heart rhythm and the heart muscle itself. These injuries can develop in the days and months after treatment, but are most often seen a year or more later.

The good news is that advances in radiotherapy over the years have lessened the incidence of cardiac injury. In addition, modern treatment protocols are often performed in partnership with a cardiologist. Their job is to assess a patient’s risk of heart injury prior to treatment and to monitor their progress during the course of radiotherapy. The goal is to craft an effective cancer treatment that doesn’t cause more health problems than it solves.

Vasectomy Is an Easy Outpatient Procedure

Dear Doctor: After three planned children and one unexpected (but much-loved) arrival, my wife and I think a vasectomy is a good idea. What will happen? How permanent is a vasectomy?

Dear Reader: A vasectomy is a safe and effective kind of birth control that works by disrupting the pathway that carries a man’s sperm. This is done via a simple elective surgery in which the vas deferens, which are the two tubes that carry sperm from the testicles to the urethra, are cut or blocked. The procedure, which is usually performed by a urologist, is close to 100% effective, with just one or two pregnancies per 1,000 procedures. The surgery can be reversed, but the success rate of future pregnancies varies.

A vasectomy is done on an outpatient basis, either in the urologist’s office or a surgery center. It’s likely that your doctor will ask you to avoid blood-thinning medications in the week leading up to the surgery. These include non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen, and also may include prescription drugs such as warfarin and apixaban. This is done to limit bleeding during the procedure. It’s important to note that you should never stop taking prescription blood thinners without first consulting with your doctor.

The procedure itself is done under a local anesthetic, so the patient is awake. In the traditional method, the surgeon uses a scalpel to make either one or two incisions in the scrotum in order to reach the vas deferens. A segment of each tube is cut away, and the open ends are sealed shut, either by cauterization or with stitches. The incisions in the scrotum are also closed up.

A newer type of vasectomy, known as the “no-scalpel” method, uses a small puncture to access the vas deferens. Studies suggest that the no-scalpel method results in less pain and fewer post-surgical complications, including infections and blood clots. Additional complications can include pain, swelling, bruising and blood in the semen. Delayed complications can include post-vasectomy pain syndrome, or PVPS. This is prolonged post-surgical discomfort or pain and occurs in 1% to 2% of cases.

Following the surgery, you’ll be asked to wear a supportive garment, such as a jock strap or tight-fitting underwear, for a day or two. Ice packs will be used to reduce swelling, and your doctor will advise you on any pain meds you may need. It’s important to rest for a day or two after surgery, and then to limit activity, such as sports or heavy lifting, for at least a week beyond that. If at any time you experience signs of infection, call your doctor immediately. These include fever and redness, swelling or discharge at the surgical site that don’t improve.

Sperm continues to be present after a vasectomy. That means it’s important to keep using birth control until a follow-up semen analysis, performed six to 12 weeks after the procedure, gives you the all-clear. And remember, although a vasectomy will prevent pregnancy, it doesn’t protect against sexually transmitted diseases. Anyone outside of a monogamous relationship should continue to protect themselves with condoms.
