  Anastomosis - Wikipedia, the free encyclopedia
A second case in which the idea of anastomosis finds application is in the theory of Symbiogenesis, in which the emergence of new forms of life (species) are seen to be emergent from the formation of novel symbiotic relationships.
Coronary anastomoses are a clinically vital subject: the coronary anastomosis is the blood supply to the heart.
anastomosis is to stitch together two cut ends of any hollow organ, usually to restore continuity after resection, or to bypass an unresectable disease process.

 Ileoanal Anastomosis - Definition, Purpose, Demographics, Description, Diagnosis/Preparation, Aftercare, Risks, Normal ...
Ileoanal anastomosis is a surgical procedure in which the large intestine is bypassed and the lower portion of the small intestine is directly attached to the anal canal.
To perform an ileoanal anastomosis, the surgeon detaches the ileum from the colon and the anal canal from the rectum.
Because an ileoanal anastomosis is a procedure that is done after a patient has failed to respond to other therapies, the patient's condition has been diagnosed by the time the doctor suggests this surgery.

The anastomosis procedure is performed by passing the end of the graft vessel through the inner lumen of the inner sleeve until the end of the vessel extends a short distance from the distal end of the sleeve.

Anastomosis of the descending hypoglossal branch to the distal stump of the hypoglossal nerve trunk is of little or no help in improving tongue dexterity.[2,3,11] One-half of the hypoglossal nerve can be cut and used for anastomosis.

 Section 5 Chapter 29 Intestinal Anastomosis
One study that examined the relative efficiency of absorbable and nonabsorbable material concluded that the strength of the anastomosis, expressed as a percentage of normal tissue strength, was essentially the same regardless of the type of suture used.
Initially, tissue eversion at the stapled anastomosis was a major concern, given that everted hand-sewn anastomoses had previously been shown to be inferior to inverted ones; however, the greater support and improved blood supply to the healing tissues associated with stapling tend to counteract the negative effects of eversion.
Even when the anastomosis had to heal under adverse conditions (e.g., carcinomatosis, malnutrition, previous chemotherapy or radiation therapy, bowel obstruction, anemia, or leukopenia), no significant differences were apparent between stapled and hand-sewn anastomoses.

All the patients with the anastomosis at chest (except those who had jejunum as a substitute organ and one case with stomach as a substitute organ) were considered for omentoplasty.
For the anastomosis at the level of neck, omentoplasty was taken as a routine policy since year 2004 with the exceptions in few cases, where it was not considered because of technical difficulties.
It is believed that covering an anastomosis, particularly the one at high risk of dehiscence (e.g., after preoperative radiotherapy), with a well vascularized flap of omentum provides oxygen and nutrients for improved healing.

 Anastomosis
An anastomosis is a surgical connection between 2 structures.
For example, when a segment of intestine is surgically removed, the 2 remaining ends are sewn or stapled together (anastomosed), and the procedure is referred to as an intestinal anastomosis.
Examples of surgical anastomoses are colostomy (an opening created between the bowel and the abdominal skin) and arterio-venous fistula (an opening created between an artery and vein) for hemodialysis.

 Anastomosis definition - Medical Dictionary definitions of popular medical terms
An anastomosis may be naturally occurring or artificially constructed and be created during the process of embryonic development or by surgery, trauma or pathological means.
An anastomosis may, for example, connect two blood vessels (as in a naturally occurring arteriovenous anastomosis, a connection between an artery and a vein) or it may connect the healthy sections of the colon or rectum after a cancerous or otherwise diseased portion has been surgically removed.
Anastomosis has been in medical usage since the Greek physician Galen (129-200 AD) used it to describe the interconnections between blood vessels.

The anastomosis is then completed with little difficulty.
The tip of the catheter is inserted into the bladder, and the anterior bladder neck is progressively sutured around the circumference of the membranous urethra without "bunching." No attempt is made to tighten the bladder neck.
Seven sutures are usually used in the anastomosis with a "racquet handle" closure, and eight are usually used if there is no bladder neck redundancy.
