anastomosis

[ə‚nas·tə′mō·səs]
(medicine)
A surgical communication made between blood vessels, for example, between the portal vein and the inferior vena cava.
An opening created by surgery, trauma, or disease between two or more normally separate spaces or organs.
(science and technology)
The union or intercommunication of parts or branches, such as blood vessels, streams, or leaf veins. Also known as inosculation.
A network of parts or branches created by the process of anastomosis.

Anastomosis

 

in animals, connections between nerves, muscles, and blood or lymphatic vessels. Anastomoses between arteries and veins, without the formation of capillary networks—that is, arteriovenous anastomoses—are of importance in regulating the blood supply of organs. In clinical practice, anastomosis is the name given to a connection between tubular organs which is artificial or has arisen as a consequence of disease. In higher plants, anastomosis is the connecting of tubular structures—for example, veins in leaves and branchings of latex vessels. In fungi, anastomosis is the connecting or concresence of two mycelium hyphae with the establishing of intercommunication between them. This occurs with an insufficiency of food and plays a role in the formation of diploid mycelium and the heterokaryon of haploid mycelium, since the cell nuclei move from one cell into another through the anastomoses.

Intestinal anastomosis was achieved using a single layer of simple interrupted suturing pattern with an absorbable braided suturing material (Catgut-3/0), (Coolman et al.
Group B: The circular mechanical stapler (EEA(tm) 21 mm and 25 mm Single-Use Stapler, (Ethicon(r), Johnson and Johnson, Pakistan) of 21 and 25 mm in diameter was used to generate end-to-end intestinal anastomosis (Martel and Boushey, 2007).
Suturing time: When intestinal anastomosis suturing times between Groups A and B were compared, a significant difference was found in the duration of operation (P[?
The aim of the current study was to determine by univariate and multivariate analyses the factors associated with clinically significant AL in patients who underwent large intestinal anastomosis (without a protective stoma).
The medical records of 647 patients who underwent large intestinal anastomosis during the study period were reviewed.
Intraoperative and Postoperative blood transfusion have adverse effects on elective intestinal anastomosis, significantly increase rate of surgical site infection, but regarding anastomosis leak and faecal fistula, post-operative blood transfusion has more adverse effects.

Both continuous and interrupted sutures are commonly used in fashioning intestinal anastomosis.
Interrupted single layer serosubmucosal suture is the "gold standard" for intestinal anastomosis and 2 is preferred hand sewen technique .
Intestinal anastomosis can be performed by a hand-sewn technique using absorbable and non-absorbable sutures or stapling device, suture anastomosis (hand-sewn technique) is the commonly used option because of the availability and affordability of suture material and familiarity with procedure.
Halsted (1887) emphasized the importance of submucosa in intestinal anastomosis because it is the strongest layer of the bowel, suture should be taken and considered as risk factor for anastomosis leak.
The key findings in this study was that post-operative complications did not differ significantly after early oral feeding with late starting of feeding after intestinal anastomosis.
