What is a bowel perforation or hole in your colon and what are the symptoms? Who is at risk? And how is a perforation treated? Overview Your colon is composed of layers of smooth muscle and mucous membranes. The innermost layer, called the mucosa, is soft and pliant—similar to the tissues in your mouth. Bowel perforations occur when a hole is made in this lining, often as a result of colon surgery or serious bowel disease. A hole in the colon then allows the contents of the colon to leak into the usually sterile contents of your abdominal cavity. Symptoms The symptoms of a bowel perforation can vary and may come on slowly or rapidly depending on the underlying cause. Symptoms may include: Abdominal pain (often severe and diffuse) Severe abdominal cramping Bloating Nausea and vomiting A change in your bowel movements or habits. Rectal bleeding Fever (usually not immediately) Chills Fatigue Risk Factors Scientists have found that a number of factors may increase your risk of developing a bowel perforation. These include both factors involved in surgery or a procedure (iatrogenic causes) and bowel diseases characterized by inflammation. Risk factors may include: Recent or prior abdominal. Recent or prior pelvic surgery. Age greater than 75. History of multiple medical problems. Trauma to the abdomen or pelvis (such as in an automobile accident.) A history of diverticular disease. A history of inflammatory bowel disease. Colon cancer Use of the monoclonal antibody immunotherapy drug ipilimumab. Pelvic adhesions (scar tissue, usually related to previous surgeries.) Female gender (women typically have a more flexible colon, which can lead to accidental perforation during medical procedures, including a colonoscopy.) Diagnostic and surgical procedures involving the digestive tract, abdomen, or pelvis. Risk factors for a perforation during a colonoscopy include being female, older age, a history of diverticular disease, and bowel obstructions. Causes Bowel perforations may occur spontaneously (unexpectedly) as a result of a medical condition or instead be a complication of various diagnostic and surgical procedures which accidentally create a hole in the colon. Trauma, especially blunt trauma to the abdomen, is also an important cause of bowel perforations. Procedure associated causes include: Enema – An improperly or forcefully inserted rectal tube for an enema can rip or push through the colon lining. Bowel preparation for colonoscopy - Rarely, the bowel preparation for a colonoscopy can result in a perforation. This is more common in people with a history of constipation. Sigmoidoscopy – Although the endoscope for a flexible sigmoidoscopy is flexible, perforation remains a risk, but a rare one. Colonoscopy – The tip of the endoscope has the potential to push through the inner lining of the colon, although this is a rare complication of the procedure and is not seen in the virtual colonoscopy. Perforation of the bowel associated with a colonoscopy is more common in those who have the severe acute disease of the bowel as well as those who are on steroid medications. The colonoscopy perforation rate appears to be around 1 in 1400 people who have screening colonoscopies and 1 of 1000 people who have a therapeutic colonoscopy (for example, to remove a polyp.) Abdominal or pelvic surgery, particularly colon surgery as for colon cancer. Causes of spontaneous bowel perforation (those unrelated to surgery or procedures) include: Inflammatory bowel disease/colitis such as Crohn's disease and ulcerative colitis. The lifetime risk of a bowel perforation with Crohn's disease is between one and three percent, making this a very common cause. Severe bowel obstruction, especially when the colon is "weakened" by diverticular disease, another process, or cancer. Trauma. Ischemic bowel disease (when the blood supply to the colon is compromised.) Colon cancer. Foreign body ingestion - Most commonly due to the ingestion of fish bones, and bone fragments, as well as non-food items. Severe bowel impaction. Diagnosis If your doctor suspects a bowel perforation, she can order tests to confirm her suspicion. A simple abdominal x-ray may show gas outside the colon but is not often diagnostic. A CT scan of your abdomen with or without contrast or a barium enema or swallow may be needed. A complete blood count may show an elevation of your white blood cell count if the perforation has been present for a while, or evidence of anemia due to bleeding. Small perforations may sometimes take several imaging studies and time to accurately diagnose. Treatment Perforation of the bowel is considered a medical emergency and requires immediate treatment. Left untreated, the contents of the bowel can leak out and cause inflammation, infection and even abscesses in your abdomen. The technical name for this is peritonitis, which is a painful precursor to sepsis—or a body-wide infection. The majority of perforations are surgically repaired. Depending on the location and size of the tear, the doctor might be able to fix it through an endoscope, similar to the one used during a colonoscopy—but this is not an option for everyone. Open bowel surgery may or may not result in a stoma and colostomy: an artificial opening outside of your stomach where stool drains into a small bag until the bowel is healed. Complications Complications of untreated perforation may include: Bleeding Infection (peritonitis and sepsis) Death Complications depend on a person's general health, as well as the amount of time it has taken to diagnose and treat the perforation. Recovery During your initial recovery period, you will not be able to drink or eat anything by mouth. This is called resting the bowels and allows the inner lining time to heal properly. You will also have a nasogastric tube in place to drain the contents of your stomach for a period of time. You may receive intravenous antibiotics and nutrition for a few days if you're in the hospital. Although you may be anxious to return to your normal routine, it's important that you give your colon time to heal properly, and follow your doctor's orders. The Bottom Line Bowel perforation may occur spontaneously, such as with inflammatory bowel disease, or during surgery or diagnostic tests. Symptoms may come on rapidly, or instead slowly, and should be considered in anyone who has risk factors for a perforation combined with risk factors for the condition. When caught early, there are different treatment options available, but even with surgery (which is most often required) the bowel can often be preserved and repaired without a colostomy. Recovery can take time, both for healing, and to correct and risk factors which led to the perforation.

Hemorrhoids are varicose (enlarged and swollen) veins around the outside of the anus or in the lower rectum. The rectum is the last part of the bowel that leads to the anus, the opening at the end of the bowel where fecal matter leaves the body. Everyone has hemorrhoidal tissue in this area that’s made up of blood vessels, connective tissue, and some muscle. These “cushions” don’t always become enlarged or distended, but as we age, this phenomenon becomes more common — causing what we call hemorrhoids, also known as piles. Hemorrhoids can be caused in a number of ways, often by straining to make a bowel movement. Lifting heavy objects, along with other activities that may cause straining, can also lead to hemorrhoids. Experiencing increased pressure during pregnancy and being overweight are other contributing factors. Hemorrhoids may be painful and particularly bothersome if they are recurrent, but they are not dangerous or life-threatening, and symptoms usually go away within a few days. There are plenty of effective ways to treat them, as well as options for the less common types of hemorrhoids that may be more problematic.

Anal Fistula When an irregular false tract occurs between the inside of the rectum and the outside skin surface, an Anal Fistula forms. The anal fistula is classified according to the condition of the tract and the relation of the internal opening to the anal sphincter muscle. Most commonly, this condition develops because of an anal abscess that went untreated. The anal abscess itself is usually the result of a small gland that becomes infected. The most common symptoms are pain, recurrent swelling, pus discharge and discomfort during the discharge of stool. The most common treatment in India is a surgical treatment; the most common method is the minimally invasive Video Assisted Anal Fistula Treatment. Symptoms What are the typical symptoms of anal-fistula? Swelling around the anal area Redness around the rectal area Pus drainage Rectal pain. Causes What causes anal fistulas? It usually occurs as a result of some damage to the tissue around the anus. It begins as a sort of inflammation in the rectal area. Later, it becomes an abscess which gets regularly infected and reinfected by faeces. This causes the fistula to form near the anus. If the fistula seals over, pus can start accumulating. Because of this pus-drain, anal fistulas can be very painful. Anal fistulas usually occur because of: An injury caused by constipation Anal glands becoming infected Crohn’s disease Abscess of the large intestine

When the skin of the anus gets cut or damaged, that is called an anal fissure. It is very similar to what happens when our dry lips get chaffed. Fissures typically bleed and cause pain, which is why they are often confused with haemorrhoids/ piles. When the anal muscles are stretched too far, it usually causes strain on the anus. This can occur to people who suffer from constipation or prolonged diarrhoea. It also occurs for older patients due to decreased blood flow to the anal area. It is not uncommon for women to develop anal fissures after giving birth as well. And it can also happen to people who have Crohn’s disease. With more severe cases of anus tearing, an external lump will form on the anus. These are the sentinel piles tell-tale of chronic fissures. The issue of anal fissures can be solved by medicine or by surgery and also by laparoscopic treatment. Symptoms Some signs and symptoms of anal fissures : Pain during bowel movement Pain after the bowel movements Blood on the stool or toilet paper Anal itching Visible damage to the skin of the anus A small lump that’s close to the anal fissure. Treatments Chemical Sphincterotomy Chemical Sphincterotomy is basically a Botox Injection for anal fissures; it is a very common Treatment for Anal Fissures. If the anal fissure doesn’t heal, it’s usually because of the spasm of the internal anal sphincter muscle which reduces blood supply to that area and further aggravation occurs to the fissure during the passage of motion through a spasmodic anal canal. The Botox is injected into the anal sphincter. This injection is used to prevent spasm and cause temporary paralytic relaxation until the tissues are renewed. The effects last for three months and the anal fissure heals during that time. Percutaneous Closed Lateral Internal Sphincterotomy This surgery, popularly known as CLIS, is a quick minimal invasive surgical method performed by specialized doctors under local anaesthesia that is used to treat chronic anal fissures. It is performed on the internal part of the anal muscle, the internal anal sphincter. The surgical procedure basically lowers the pressure of the internal anal sphincter and the spasm is reduced by dividing this internal anal sphincter. The fissure is healed because anal spasm is lowered and blood flow to the area is improved. Due to the closed technique, the wound is smaller and it heals faster.
