Polypectomy is a procedure to remove a colon or gastric polyp. When a colonic or gastric polyp or polyps are detected by colonoscopy,
polypectomy should be done to assure that an invasive malignant tumoris
not present. because there is strong evidence of a premalignant potencial
for colonic polyps. Using computer-controlled electrocautery current, the base of the polyp
is first cauterized to prevent bleeding and then the stalk beneath is
severed with the wire loop.
Polypectomy can be defined as the endoscopic resection of polyps or tumors,
obviating the need for open surgery. This is one of the most important
scientific advances in the field of gastroenterology, since it enables
us to treat many gastric or colonic tumors, without the inconvenience
associated with major surgery. Our clinic has acquired a respectable experience
in this procedure , having seen and treated many cases with this method,
cases ranging from patients with small solitary polyps to multiple polyposis
with numerous tumors. In one case , we resected 108 polyps from the same
patient (in several sessions, over a period of four years), a feat which
is considered a "World Record" by some of our colleagues.. The procedure
or endoscopic polypectomy involves the introduction of a special wire
through the endoscope which is connected to a surgical snare-cautery
devise, enablelng the wire to cut and coagulate within the lumen of
the bowel. Once the polyp is detected endoscopically, it can be resected
with the use of this wire and any resultant bleeding can be controlled
by this device{s possibility to coagulate. This procedure can be performed
on an outpatient basis, eliminating the need for hospitalization. Normal
everyday activity may be resumed almost instantly by the patient. The sequence below shows the step by step extraction of one of the largest
polyps we have encountered. I can only remember one other polyps to be
larger, which was extracted in several sections. 72 year old female who complained of hemorrhoids. She effectively did
have hemorrhoids, but on digital rectal examination a large tumor was
found before the first valve, which later proved to be a villous adenoma
with dysplastic cells.
