Watermelon colon treated by argon plasma coagulation

Gastrointestinal Endoscopy, 2005
report of a gastric ulcer as a direct result of an LVAD or any other implantable device. We speculate that the gastric ulcer and subsequent perforation in our patient was caused by local ischemia that resulted from pressure exerted by the device on the gastric wall. Each mechanical pulsation of the device may further increase the pressure damage.

Argon plasma noise temperature similarity

IEEE Transactions on Electron Devices, 1975
Noise temperature data from argon plasmas at 1-50 mmHg are given. Similarity is shown to exist when the discharge currents are scaled according to a constant current/radius ratio. The consequences of the new method of scaling are discussed.

Argon Plasma Coagulation for Inferior Turbinate Reduction

Annals of Otology, Rhinology & Laryngology, 2000
Surgical reduction of the inferior turbinate remains a widely used therapy for nasal obstruction caused by hyperplastic turbinates. Current methods are costly and time-consuming, require nasal packing, and cause extended postoperative swelling. Argon plasma coagulation (APC) is a new, innovative technique in otorhinolaryngological surgery that is ...

NEW ARGON PLASMA COAGULATION METHOD FOR SUPERFICIAL ESOPHAGEAL CARCINOMAS: ARGON PLASMA COAGULATION‐SUBEPITHELIAL ABLATION

Digestive Endoscopy, 2007
Argon plasma coagulation (APC) has been introduced to the field of therapeutic endoscopy and is now widely used. A new ablation technique is herein proposed for the treatment of superficial esophageal carcinomas. According to this technique, after the initial ablation, we exfoliate the epithelium and then perform a second ablation (APC‐subepithelial ...

Argon plasma electrosurgical coagulation.

Biomedical sciences instrumentation, 1998
Both argon plasma electrosurgical coagulation (APEC) and conventional electrosurgical fulguration (CEF) apply electrosurgical energy to the target tissue through a plasma. Presented here is a detailed examination of this process. Consideration of the fundamental processes and characteristics of plasmas and the various parameters they are dependent upon

Argon plasma coagulation in endoscopy

1997
Argon plasma coagulation (APC) represents a new method of contact-free electrocoagulation in which energy is transmitted to the tissue through ionized argon gas. Its application has been used with success in open surgery. After design and development of special endoscopic probes, APC was introduced in flexible endoscopy in 1991 in Tuebingen, Germany ...

Zustandsänderungen im isothermen Argon‐Plasma

Beiträge aus der Plasmaphysik, 1960
AbstractDie nachfolgende Rechnung und das aus ihr entwickelte Diagramm befassen sich mit den möglichen thermodynamischen Zustandsänderungen eines strömenden Argon‐Plasmas in den Druck‐ und Temperaturbereichen 10 < p < 3 · 106 dyn/cm2 und 5000 < T < 26000 °K.

Argon Plasma Coagulation in Gastroenterology

2018
Interventional procedures are a milestone in the evolution of digestive tract endoscopy. Argon plasma coagulation (APC) is a well-established technique included in the endoscopic armamentarium. This device is intended for thermal coagulation of tissues and originally APC developed as an alternative to laser in open and laparoscopic surgery.
