The property controlled excision " on the basis of ensureing clinical efficacy, improves the safety of operation, reduces complication, reduce " second operation "
Incidence is the important topic of carcinoma of the rectum surgery.The most common complication of rectal cancer surgery is " anastomotic leakage ", and incidence is
10-20%, there are two types of the processing modes that anastomotic leakage occurs, and one is small for previous anastomotic leak, and leakage quantity is few, drains, can be by drawing
The expectant treatments such as stream, anti-inflammatory are cured；Another is that leak is big, leakage quantity is more, drainage effect is poor, and the excrement sample enteral containing a large amount of bacteriums is held
Object leaks into abdominal cavity, and infection occurs infectious shock, jeopardize trouble quickly in the rapid disperse in abdominal cavity, secondary acute peritonitis, severe patient
Person's life, therefore this some patients has to promptly receive " the fistulization operation " for the purpose of saving life, in time holds enteral
Object turn of tidal stream receives third time " closing fistula " operation, huge injury is brought to patient's body and mind again after mouth to be anastomosed leakage healing after the several months.Cause
How this improves the treatment rate of anastomotic leakage, avoids " secondary to close fistula operation " and because the third time that row " fistulization " is brought " is closed
Fistula " is performed the operation, and is the intractable technical barrier that current carcinoma of the rectum surgery faces.
The method that prevention and treatment anastomotic leakage mainly uses placing peritoneal cavity drainage at present, diameter about 5-8mm is common
Several side openings are cut in latex or silicone tube one end, are placed near previous anastomotic, outside other end lead body, occur in anastomotic leakage hindgut
It is tolerant by peritoneal cavity drainage tube lead body outside, play the role of early warning and treatment.But in actual use, because drainage tube is placed on
Side, the homonymy anastomotic leakage for adjoining drainage tube is easy drainage, and is not easy to draw if the leakage such as offside far from drainage tube, and drains
Tube capacity easily gives a discount in vivo, side opening is easy blocking, drainage tube coverage area is small, and drainage effect is poor.Therefore patient is often because coincideing
Mouth leakage drainage effect is bad and has to receive to perform the operation again, and greatly psychology and financial burden are brought to patient.
But if anastomotic leakage can guarantee adequate drainage, outside the timely lead body of excrement sample intestinal contents, secondary acute abdomen is avoided
Film is scorching, then anastomotic leakage overwhelming majority energy self-heal, to avoid " secondary fistulization operation ", and then avoids third time " closing fistula "
Operation, reduces the additional increased two operations brought by anastomotic leakage complication, and what thus reduction was brought makes patient's body and mind
At huge injury.But the drainage device of rectal cancer surgery does not have essential change, clinic to continue to use more over nearly more than 100 years
