A 28-year-old man presented with a 9-year history of chronic ulcerative colitis (UC), treated initially with Asacol and more recently with Imuran, and rectal polyps. Biopsies one year ago were diagnosed as adenoma-like low grade dysplasia in association with chronic active colitis. The patient subsequently underwent a transanal excision of the irregular folds, and the tissue sections were read as markedly inflamed hyperplastic polyps with superficial mucosal ulcerations and no evidence of dysplasia or malignancy. The patient now has recurrence of a circumferential nodular mucosal fold in the rectum that is concerning for malignancy, in addition to a continuous inflammatory process involving the rectum and left colon. The right colon is relatively free of inflammatory disease. Biopsies were obtained.
A surgical procedure to disconnect the lower part of the small bowel from the bowel and pulling it through an incision in the abdominal wall is known as ileostomy surgery. There can be various reasons that your doctor may choose to give you an ileostomy. Those reasons mainly include ulcerative colitis, Crohn’s disease, cancer, and familial polyposis.
The main aim of an #ileostomy is to divert the passage of wastes away from the colon and towards an opening in the #abdomen. This opening is known as a stoma. The surgeon does it after removing or resting the diseased part of the bowel. It allows bodily wastes to leave the body through the stoma. This surgical procedure is generally a lifesaving operation.
Another type of #intestinal #ostomy is the #colostomy, which involves pulling out of a part of the colon. The surgeon, during colostomy surgery, dissects the colon to separate the healthy section of the colon from the diseased part. He then pulls the healthy end out of a cut in the abdomen to create a stoma after removing or resting the diseased section. The surgical technique to create an ileostomy is the same as that of a colostomy.
Ileostomy surgery
The surgeon puts the patient to sleep by administering general #anesthesia. The place of the stoma will depend on the site of the illness and the patient’s preferences or needs. The incision to start the procedure is usually 8 inches long down the midline on the patient’s abdomen. This incision dissects the abdominal skin, muscles, and subcutaneous tissues. The procedure may involve the removal of the #colon alongside or excluding the colon and rectum, depending on how much the disease has spread. The surgeon also closes the anal canal with the help of stitches.
An ileostomy can be temporary or permanent, based on the type or severity of the disorder. The two basic types of permanent ileostomy are a convention and continent ileostomy. The convention or Brooke ileostomy necessitates the patient to wear an ostomy bag the entire time. The stoma drains all the fecal materials into the ostomy bag. With this ileostomy, you are going to have no control over when you move your bowels, as a stoma doesn’t have any #sphincter #muscles. A continent ileostomy consists of an internal reservoir inside the abdomen. There will be a stoma on the belly, but it will not need an ostomy bag to cover it. You will be able to draw waste materials out of your internal pouch through a flexible catheter. The two types of continent ileostomy include a Kock pouch and BCIR.
Contrary you what you may have been thinking, an ileostomy gives you a chance to start a healthy and happy life after getting rid of the life-threatening condition. Some people acknowledge that their ileostomies have helped them to be even more active and healthier after the procedure because their quality of life was not that good before surgery due to illness. It all comes down to the mindset.
If you have a bowel condition so severe that your doctor recommends an ileostomy, be sure to discuss everything and clear your doubts instead of being stressed about the prospects of losing a body function.
The tumor consists of anaplastic polygonal cells in sheets with no tubular, cribriform, or villous differentiation. There is brisk peritumoral lymphocytosis, as well as some intratumoral lymphs.

The surgical procedure in which the surgeon brings an end of the small #intestine out through the belly is known as ileostomy surgery. The end of the small intestine sticks out on the abdominal wall to form a stoma. An ileostomy can be temporary or permanent.
You may require a temporary #ileostomy if your lower bowel needs to rest for a specific duration to heal. Ileostomy surgery is generally a part of colorectal cancer surgery, diverticulitis surgery, or J-pouch surgery to treat familial polyposis or ulcerative colitis. The surgeon will most likely construct a loop stoma to give you a temporary ileostomy.
You may need a permanent ileostomy if your large intestine needs to be removed, or your anus stops functioning due to a severe condition. Reasons you may need a permanent ileostomy may include Crohn’s disease, #colonic dysmotility, ulcerative colitis, familial #polyposis, and some #cancers. You will probably need an end stoma for the permanent ileostomy.
Caring for ileostomy
Caring for your ileostomy almost entirely involves the use of the ostomy pouch. For this purpose, you may be looking at a wide range of options to pick the one that fits your requirements and lifestyle. You will be able to purchase ostomy supplies from local medical supply stores or by ordering online.
Living with an ileostomy
All you need is to remain motivated to get back to your healthy self after ileostomy #surgery. Once your bowel recovers, you will be able to live normally. A few aspects of living with an ileostomy are worth mentioning here.
• Unless your job requires you to lift heavy objects, you should be able to return to your workplace. There will undoubtedly be some changed in your routine due to pouching requirements, but effective management won’t let these interruptions affect your work. You may also talk to your employer and coworkers about your ileostomy.
• Having an ileostomy doesn’t mean that you are going to have to say goodbye to your social life. You may be concerned about the leakage and odor, but the good news is that modern-day ostomy supplies prevent leakages and odors in the best possible way.
• The location of the ileostomy is just above the beltline, meaning that you can wear anything you want. Ostomy appliances remain flat with the belly. You can also wear an ostomy belt to keep your ostomy appliance snugly in place.
• You can resume your physical training regimen after ileostomy surgery. You are going to have to allow your bowel to recovery, though. You can play all sports, but make sure that they do not involve lifting too heavy objects because it can cause harmful stress on your stoma. You can talk about it with your doctor or ET.
• You may have to commit to a selected diet plan right after surgery, and continue with it until your bowel fully recovers. Once your bowel heals, you can start introducing your favorite foods back into your diet.
It is best to remain in touch with your #ostomy care nurse and doctor. Managing an ileostomy is not hard. You just have to have the right information. Your doctor and ET are the authentic sources that can provide you the accurate information about how to live with an ileostomy or any other kind of ostomy.
There are two types of bowel #ostomies: colostomy and ileostomy. An ileostomy refers to an intestinal diversion, which results in the part of the #ileum being pulled out of an incision in the belly. Resultantly, the feces pass out without proceeding to the colon. A colostomy, on the other hand, is when the surgeon pulls out a part of the colon through a cut in the belly. Both ostomies result in an opening in the abdomen. This opening is known as the stoma.
Both the colostomy and ileostomy can be permanent or temporary, depending on the underlying condition.
Why may you need a colostomy or ileostomy?
Your surgeon may want to give a colostomy or ileostomy when you need the removal or bypassing of a part of your bowel. An ileostomy or colostomy may be a part of the treatment for following health conditions or reasons.
• Cancer in the rectum, anus, or colon
• Inflammatory bowel #disease
• Familial adenomatous #polyposis (FAP)
• Bowel obstruction
• Injury
• Diverticulitis
Locations of a colostomy or ileostomy
The location of a #bowel ostomy depends on the site of the infection. A colostomy is divided into four subtypes, and each subtype gets its name from the location of the ostomy.
• A colostomy in the sigmoid colon is known as a sigmoid colostomy. This one is the most common colostomy type.
• A colostomy in the descending part of the #colon is called a descending colostomy. It is located on the left side of the abdomen.
• A colostomy in the transverse portion of the colon is known as a transverse colostomy. It is located somewhere in the upper abdomen.
• A colostomy in the ascending part of the large intestine is known as the ascending colostomy. It is the part of the colon that connects with the ileum. It is the least common type of colostomy.
• An ileostomy, as the name suggests, is created on the ileum, which is the end of the small intestine.
The location of the bowel ostomy determines the consistency of the stool passing out of the stoma. The primary function of the colon is to absorb water from the stool as it proceeds towards the rectum and anus. There will be more watery stool passing out of the stoma if the surgeon removes more length of the colon. That said, an ileostomy results in more water consistency of the stool, as it bypasses the entire colon.
What happens after surgery?
After surgery, you will need to stay in the hospital for 5-10 days, depending on the duration of the initial recovery. The doctors will give you pain medication to help you remain comfortable. You will need to limit your diet to liquids for a couple of days after surgery. You can introduce solid foods into your diet gradually.
Right after surgery, the stoma will be swollen. Its color and overall appearance will be much like the inside of your mouth. The stoma has a lot of blood vessels that can cause it to bleed when you rub it, but the absence of nerve endings in it means that you won’t feel any pain.
The overall recovery after ostomy surgery can last up to six or eight weeks. During this time, your doctor will instruct you to limit your physical activities, and stick to a more restricted diet. You will be able to introduce your favorite foods back into your diet gradually after the recovery phase is over.
Presumed Familial Polyposis: Multiple colonic polyps (<20) was seen in the right colon of this 76 years old male with a past history of rectal carcinoma resected 12 years previously. Histology of these polyps was that of tubular adenoma. He had 4 polyps including villous adenoma removed 4 years previously from the same right colon; and his upper endoscopy revealed duodenal hyperplastic polyp. He refused genetic testing and denied any family history fo colorectal neoplasm.
Note that the cancer (left) meets normal mucosa (right) abruptly, with no evidence of a pre-existing adenoma.

Ulcerative colitis is associated with acute and chronic inflammation of the colon. There is a loss of the normal haustral folds and the colon may become tubular. "Pseudo-polyposis" may also occur with regenerative tissue of the normal colon.
Note multiple polyps (mostly pedunculated) and at least one large mass at the hepatic flexure coated with contrast.

Found this in my purse as I was rummaging around for a Certs. Hmm, now who could this be from . . . I wonder. Had I set my purse up upon the counter while talking to Shelby at that horrid establishment? I must have, whereupon she must have slipped it in; anyways, I’ve half a mind to turn this car around, drive back there and give that girl a piece of my mind, both concerning her general demeanor and her apparent “sex-positive” “lifestyle”. Lifestyle. Please. Gays get a pass from using that word since they still face acute discrimination, if not outright savage persecution (looking at you witheringly, Iran). Everyone else, ugh. Just ugh.
And just what point had Shelby intended to get across by slipping me this in the first place? Is it some kind of oblique come-on? Disgusting! I must be nearly twenty years her senior!
Andrew and I toured Coco the Colossal Colon tonight. He did not want to climb through it, but agreed to keep me company. You can tell he's secretly having a blast.
