Hybrid-APC Margin Ablation to Prevent Post EMR Adenoma Recurrence

2019-07-16 10:38:48 | BioPortfolio

Summary

Endoscopic Mucosal Resection (EMR) is the current standard for effective endoscopic resection of such colon adenomas. If resection is possible in one piece (so called "en bloc" resection) then recurrence rates are low. However, most non-pedunculated polyps >2 cm are removed in pieces ("piece-meal" resection) which leads to disease recurrence rates between 12-30%. In the March 2019 issue of Gastroenterology Bourke et al. presented that post EMR ablation of the resection margins using soft coagulation with the tip of a resection snare reduces adenoma recurrence to 5% compared to 21% recurrence found in the control group. Hybrid Argon Plasma Coagulation (h-APC) combines an ablation technique (APC) with the option for submucosal saline injection using a high-pressure water jet. The technique allows to lift dysplastic epithelium thus creating a safety cushion under the mucosa is lifted with a saline injection and then to ablate larger areas more thoroughly and with a higher energy setting, with a low risk for side effects or complications.

Medical and Biotech [MESH] Definitions

A method of tissue ablation and bleeding control that uses argon plasma (ionized argon gas) to deliver a current of thermocoagulating energy to the area of tissue to be coagulated.

Ionized gases, consisting of free electrons and ionized atoms or molecules which collectively behave differently than gas, solid, or liquid. Plasma gases are used in biomedical fields in surface modification; biological decontamination; dentistry (e.g., PLASMA ARC DENTAL CURING LIGHTS); and in other treatments (e.g., ARGON PLASMA COAGULATION).

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
