Haemostasis with APC
Non-contact coagulation procedure with superior quality of hemostasis
|
Thermal hemostasis using the ERBE APC 2 is achieved with relatively low energy outputs and thermal heating of the tissue. Argon-Plasma Coagulation (APC) is frequently used to treat chronic, actively bleeding, non-varicose lesions of the gastrointestinal tract. Especially diffuse venous and arterial oozing bleeding can be controlled very well by APC. To treat diffuse bleeding of large surfaces such as occur with ulcerous bleeding, it is necessary to carry out coagulation over a larger surface while limiting the penetration depth. Effective APC modes and various APC probes with diverse beam forms (see detailed fig. 1) generate the necessary tissue effects for a safe hemostasis. |
Indications
- Superficial and small vascular hemorrhages
- Tumor bleeding
- Radiation proctitis
- Vascular malformations, i.e. GAVE syndrome, angiodysplasias, teleangiectasias
Advantages of ERBE equipment
- Non-contact procedure, no sticking of the instrument tip to the tissue
- Effective, even surface coagulation, for uniform hemostasis and devitalization
- Better dosage of penetration depth leads to safer application
- Limited risk of perforation
- Minimal carbonization and smoke plume formation, minimal pollution through unpleasant odors
- Safe procedure with few complications

Operation steps

Treatment of Radiation Proctitis
Radiation proctitis can take the form of teleangiectasias and hemorrhagic mucosal changes in the area of the rectum
(see fig.). The use of APC to treat radiation proctitis is already established; it can lead to an improvement of symptoms and bleeding episodes after an average of two sessions carried out at an interval of three to four weeks.

Angiodysplasia located in the gastric antrum
Usually an application using a low energy output is sufficient to staunch the bleeding. The use of low energy outputs also helps to minimize the risk of perforation in thin-walled areas (e.g. the small intestine or the right colon), where angiodysplasias often occur.
