What is intestinal anastomosis?
An anastomosis is a medical term used to describe connection or opening between two organs or tissues. When a part of the small or large intestine is surgically removed due to a disease or condition, the two sections of the remaining part of the intestine are joined together (intestinal anastomosis) to re-establish the continuity of the intestine.
Why is intestinal anastomosis done?
The intestinal anastomosis is performed following the surgical removal of part of the intestine due to intestinal diseases ore cancers. Removal of parts of the intestine may be necessary for the following conditions:
- Intestinal gangrene (tissue death due to loss of blood supply)
- Malignancy (cancer)
- Benign tumors (e.g., intestinal polyps, intussusception, worm infestations with intestinal obstruction)
- Infections tuberculosis complicated with stricture or perforation)
- Perforations due to infection, ulcers or trauma
- Damage to the intestine due to radiation therapy.
- Complications with bleeding, stricture or perforation
- Inflammatory bowel disease, ulcerative colitis or Crohn disease
- Scarring and adhesions causing the intestinal block
- Chronic constipation
- Birth defects of the intestine (e.g. Meckel’s diverticulum, cysts, Hirschsprung disease)
Intestinal resection and anastomosis are performed during the same procedure. The procedure may be done in adults and children.
When to avoid intestinal anastomosis
The intestinal anastomosis may not be feasible in conditions with a high risk of anastomotic leakage. In such cases, the surgeon may advise alternative techniques.
The intestinal anastomosis is avoided in patients with the following conditions:
How is intestinal anastomosis performed?
The intestinal anastomosis is performed under anesthesia. After removal of the part of the small or large intestine, the remaining two sections are anastomosed using sutures or surgical staples.
What are the three types of intestinal anastomosis?
The surgeon decides on which surgical technique to perform the intestinal anastomosis based on the patient and the condition. The three types of intestinal anastomosis are::
- Side-to-side anastomosis: In this technique, the sides of each part of the bowel are either sutured or stapled rather than the two ends.
- End-to-end anastomosis: In this technique, the two open ends of the intestines are connected.
- End-to-side anastomosis: In this technique, the end of the intestine which is smaller is connected to the side of the larger section.
What are the complications of intestinal anastomosis?
Like any major surgery, there is a risk of complications during and after the anastomosis surgery. Some common complications are:
- Reaction to anesthesia
- Localized blood clot and smaller blood clots which enter the blood vessels causing heart and lung complications.
- Damage to surrounding structures
- Scarring and adhesions, causing intestinal narrowing and/or blockage
- Wound dehiscence (a condition where the cut made during a surgical procedure separates or ruptures after being stitched together)
- Anastomotic leak (intestinal contents may leak through the site of anastomosis) which may lead to systemic infection
- Altered bowel movements

Indigestion (Dyspepsia, Upset Stomach Pain)Indigestion (dyspepsia) can be caused by diseases or conditions that involve the gastrointestinal (GI) tract, and also by some diseases and conditions that do not involve the GI tract. Indigestion can be a chronic condition in which the symptoms fluctuate in frequency and intensity. Signs and symptoms that accompany indigestion include pain in the chest, upper abdominal pain, belching, nausea, bloating, abdominal distention, feeling full after eating only a small portion of food, and rarely, vomiting.
Is Sepsis Contagious?Sepsis is a potentially life-threatening infection that may be caused by: bacteria, fungi, viruses, or parasites. Sepsis spreads within the body from the infection site. Treatment of sepsis typically involves the administration of intravenous medications.
SepsisSepsis (blood poisoning) is a potentially deadly infection with signs and symptoms that include elevated heart rate, low or high temperature, rapid breathing and/or a white blood cell count that is too high or too low and has more than 10% band cells. Most cases of sepsis are caused by bacterial infections, and some cases are caused by fungal infections. Treatment requires hospitalization, IV antibiotics, and therapy to treat any organ dysfunction.
The Digestion Process (Parts, Organs, and Functions)Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestive process also involves creating waste to be eliminated, and is made of a series of muscles that coordinate the movement of food. Learn more about digestion and the body parts that make it possible, including the mouth, pharynx, esophagus, stomach, small intestine, colon, rectum, anus, pancreas, liver, and gallbladder.
What Is Distal Gastrectomy Surgery?Antrectomy (distal gastrectomy) is a procedure that involves surgical removal of the lower 30% of the stomach (antrum). Surgeons follow removal by creating an attachment with an opening (anastomosis) from the remaining portion of the stomach to the duodenum (gastroduodenostomy) or the jejunum (gastrojejunostomy) of the small intestine. This surgery treats severe gastric ulcers and stomach tumors.
