Ulcerative Colitis
Ulcerative colitis is an condition of inflammation or ulcers in the lining of the large intestine, rectum and colon. Rarely is the small intestine affected by ulcerative colitis. Ulcerative colitis is also referred to as proctitis. While this condition can affect anyone, it is noticed more often in the US, England, Eastern Europe and persons of Jewish ancestry. Ulcerative colitis is a chronic condition that is often noticed to run in families. The symptoms of Ulcerative colitis are similar to Crohn's disease. But this disease tends to affect the small intestine or the mouth, esophagus, appendix or duodenum. Ulcerative colitis and Crohn's disease are both inflammatory bowel diseases. Typical symptoms of Ulcerative colitis include fatigue, nausea and severe abdominal cramps. Rectal bleeding and diarrhea are noticed with persons suffering from Ulcerative colitis, though the intensity depends on the inflammation. There is loss of appetite and weight loss. The symptoms may tend to recur at regular intervals or when eating highly seasoned food or raw fruits and vegetables. Other conditions such as hepatitis, osteoporosis, anemia and arthritis are sometimes triggered by Ulcerative colitis.
Ulcerative colitis has been traced to abnormal disorder of the immune system of the intestine. Consequently the immune system triggers off an inflammation of the intestinal tissues. Often a diet high in fat and refined foods may be responsible for ulcerative colitis. Symptoms of ulcerative colitis tend to come in spurts, with periods of acute illness followed by periods of remission. If left untreated, persons suffering from ulcerative colitis carry significant risk of carcinoma. Treatment for ulcerative colitis is based on the seriousness of the condition. While medication can help in most cases, surgery is resorted to for severe inflamation and life-threatening condition. Medications cannot cure ulcerative colitis but they can help in maintaining periods of remission. The patient can enjoy a better quality of life. Anti-inflammatory and immunomodulators are prescribed for patients of ulcerative colitis to reduce inflammation.
Colonoscopy
Colonoscopy allows the doctor to look into the interior lining of the large intestine. Through this procedure, the doctor is able to detect inflamed tissue, abnormal growths, polyps, tumors and ulcers. Early signs of cancer in the colon and the rectum can also be detected through colonoscopy. This procedure is also used to study unexplained changes in bowel habits, to evaluate symptoms of abdominal pain, rectal bleeding and sudden weight loss. The colonoscope is a thin flexible instrument whose length ranges from 48 inches to 72 inches. A small video camera is attached to the colonoscope so that photographic, electronic or videotaped images of the large intestine can be taken. Colonoscope is used to view the entire colon as well as a small portion of the lower small intestine.
The colon should be completely empty for colonoscopy to be thorough and safe. The liquid diet should be clear of any food colorings. It should be fat free. The colonoscope is gradually inserted into the rectum and slowly guided into the colon. The scope transmits an image of the inside of the colon onto a video screen so that the doctor can carefully examine the lining of the colon. The scope blows air into the colon and inflates it so that the doctor has a better view of the colon. During the procedure, the doctor is able to remove abnormal growths like polyp in the colon.
Colonoscopy aids the doctor to remove most polyps without abdominal surgery.
Colonoscopy is more accurate than a routine x ray to detect polyps, tumors, ulcers and cancers at early stage.
Colonoscopy is done most often to investigate and find the cause of blood in the stool, abdominal pain and diarrhea.
Certain patients with previous history of polyps or colon cancer, patients with family history of particular malignancies, colon problems are advised to have periodic colonoscopies because they are at greater risk of polyps or colon cancer.
Virtual colonoscopy: Here the technique that is adopted uses a CAT scan to construct virtual images of the colon. These images are similar to the views of the colon obtained by direct observation through colonoscopy. However, virtual colonoscopy cannot find small polyps which are less than 5 mm in size. These can be seen by the traditional colonoscopy. Virtual colonoscopy is not as accurate as colonoscopy in finding cancers or pre-malignant lesions that are not protruding. Virtual colonoscopy also cannot remove polyps.
Inguinal Hernia
A hernia is used to describe a condition where A loop of the intestine enters the inguinal canal in the groin region. This creates a bulge through a weakened spot or tear in the abdominal wall. An inguinal hernia is a situation where the hernia occurs near the groin on account of any inherent weakness of the inguinal canal. Obesity, lifting of heavy objects and multiple pregnancies can lead to an inguinal hernia. Inguinal hernia is a common type of hernia that affects thousands each year. It is noticed that men tend to suffer inguinal hernia condition more often than women. This is because of the weakness of the inguinal canal in men that occurs due to descent of the testicales into the scrotum.
In many cases, there are no symptoms of inguinal hernia. But some patients notice a lump in the groin region near the thigh. In rare cases, an inguinal hernia can lead to blockage of the intestine. There might be discomfort in the groin area when bending or lifting. This might be accompanied by swelling or pain in the scrotum. Certain conditions like cystic fibrosis or chronic constipation can lead to an inguinal hernia. Those with a family history of hernias are more susceptible to developing an inguinal hernia. Smoking, obesity and pregnancy can increase your risk of developing a hernia.
Surgical treatment of inguinal hernia involves removal of the protruding part of the intestine and repair of the abdominal wall. In some cases, all potential hernial openings are secued with patches. This surgery is performed either by laparoscopy or conventional abdominal incision. Large hernias cannot be treated with laparoscopy.
