Adhesions

Adhesions are bands of scar-like tissue. Normally, internal tissues and organs have slippery surfaces so they can shift easily as the body moves. Adhesions cause tissues and organs to stick together. They might connect the loops of the intestines to each other, to nearby organs, or to the wall of the abdomen. They can pull sections of the intestines out of place. This may block food from passing through the intestine.

Adhesions can occur anywhere in the body. But they often form after surgery on the abdomen. Almost everyone who has surgery on the abdomen gets adhesions. Some adhesions don't cause any problems. But when they partly or completely block the intestines, they cause symptoms such as:

• Severe abdominal pain or cramping
• Vomiting
• Bloating
• An inability to pass gas
• Constipation

Adhesions can sometimes cause infertility in women by preventing fertilized eggs from reaching the uterus.

No tests are available to detect adhesions. Doctors usually find them during surgery to diagnose other problems.

Some adhesions go away by themselves. If they partly block your intestines, a diet low in fiber can allow food to move easily through the affected area. If you have a complete intestinal obstruction, it is life-threatening. You should get immediate medical attention and may need surgery.

Anal Disorders

What is the anus?

Your anus is the opening at the end of your large intestine. It is where stool (poop) leaves your body.

Problems with the anus are common. They include:

• Hemorrhoids
• Abscesses
• Fissures, small cracks or tears in the lining of your anus
• Anorectal fistula, an abnormal tunnel from your anus or rectum to the skin surface
• Anal itching (pruritus ani)
• Cancer

Your symptoms will depend on which disorder you have. But some of the more common symptoms may include:

• Bleeding
• Discharge
• Itching
• Pain
• Swelling

To make a diagnosis, your health care provider will ask about your symptoms and medical history. Depending upon your symptoms, your provider may:

• Check the skin around your anus for anything that looks abnormal.
• Perform a digital rectal exam (DRE). For this exam, your provider inserts a lubricated, gloved finger into the lower part of your rectum to feel for lumps or anything unusual.
• Order tests, such as an anoscopy.

You may be embarrassed to talk about your anal troubles. But it's important to let your provider know about your symptoms, especially if you have pain or bleeding. The more details you can give about your problem, the better your provider can help you.

Treatments vary, depending on the condition you have.

Appendicitis

The appendix is a small, tube-like organ attached to the first part of the large intestine. It is located in the lower right part of the abdomen. It has no known function. A blockage inside of the appendix causes appendicitis. The blockage leads to increased pressure, problems with blood flow, and inflammation. If the blockage is not treated, the appendix can burst and spread infection into the abdomen. This causes a condition called peritonitis.

The main symptom is pain in the abdomen, often on the right side. It is usually sudden and gets worse over time. Other symptoms may include:

• Swelling in the abdomen
• Loss of appetite
• Nausea and vomiting
• Constipation or diarrhea
• Inability to pass gas
• Low fever

Not everyone with appendicitis has all these symptoms.

Appendicitis is a medical emergency. Treatment almost always involves removing the appendix. Anyone can get appendicitis, but it is more common among people 10 to 30 years old.

Bile Duct Diseases

Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.

Different diseases can block the bile ducts and cause a problem with the flow of bile:

• Gallstones, which can increase pressure in the gallbladder and cause a gallbladder attack. The pain usually lasts from one to several hours.
• Cancer
• Infections
• Birth defects, such as biliary atresia. It is the most common reason for liver transplants in children in the United States.
• Inflammation, which can cause scarring. Over time, this can lead to liver failure.

Bladder Diseases

The bladder is a hollow organ in your lower abdomen that stores urine. Many conditions can affect your bladder. Some common ones are:

• Cystitis - inflammation of the bladder, often from an infection
• Urinary incontinence - loss of bladder control
• Overactive bladder - a condition in which the bladder squeezes urine out at the wrong time
• Interstitial cystitis - a chronic problem that causes bladder pain and frequent, urgent urination
• Bladder cancer

Doctors diagnose bladder diseases using different tests. These include urine tests, x-rays, and an examination of the bladder wall with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
