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.

The nasoduodenal tube previously inserted is pulled through the anastomosis under vision and in case of doubts of distal obstruction saline is injected to test the canalization; finally, the ventral part of the anastomosis is laid to complete it, Figures 5(a) and 5(b).
The abdominal cavity was reopened and the degree of adhesion formation was assessed using the following scale: 0 = no adhesions; 1 = minimal adhesions, mainly between the anastomosis and the omentum; 2 = moderate adhesions occurring between the omentum and the anastomotic site and between the anastomosis and a loop of small bowel; and 3 = severe and extensive adhesions, including abscess formation [28].

Owing to adverse effects of pelvic irradiation on wound healing and colorectal anastomosis leakage as well as significant complications of fecal diversion by temporary loop ileostomy, we aimed to investigate the effect of HAM on the prevention of colorectal anastomosis leakage after neoadjuvant radiotherapy.
There was significant difference (p < 0.05) in AL between stapled and hand-sewn colorectal anastomosis. A Cochrane review of colorectal anastomosis after right hemicolectomy showed that the total anastomotic leakage rate in the stapler group was significantly reduced.17 An interesting subgroup analysis conducted by Friend PJ et al.18 found that there was more anastomotic leakage in hand-sewn colorectal anastomosis when analysing the anastomosis alone.
All five patients underwent total laparoscopic pancreaticoduodenectomy and intracorporeal anastomosis. Conversion laparotomy was not made during the operations.
Group A(arginine+glutamine+HMB): Received7 days of standard chow food plus arginine+glutamine+HMB rich diet preoperatively followed by right colonic transection and end-to-end anastomosis and received 7 days of standard chow food plus arginine+glutamine+HMB rich diet postoperatively before being sacrificed (n=10).
The pathology report described: a tumor with solid architecture, entirely invading the muscularis propria and extending into the perigastric adipose tissue without infiltration of the serosa; infiltration of the small intestine at the anastomosis site.
The purpose of this study is to investigate the surgical recurrence of Chinese populations suffering from CD with primary bowel resection and one-stage anastomosis in a specialist IBD medical center at the Nanjing General Hospital in Nanjing, in eastern China, and to identify risk factors for surgical recurrence of CD.
In this video, we review some background information surrounding a tubal reversal, followed by demonstration of a robotic interpretation of a 2-stitch anastomosis technique in a patient who successfully conceived and delivered.
