This is a 57 year-old, Female with liver cirrhosis and esophageal varices, who was scheduled in another institution for total gastrectomy. Was referred to our unit for a second opinion. Endoscopic Mucosectomy Is Performed.

Early gastric cancer (EGC) is defined as invasive gastric cancer that invades no more deeply than the submucosa, irrespective of lymph node metastasis (T1, any N). While EGC is of particular importance for patient care in Eastern Asia, its significance extends to other disciplines and patient populations.

Early Gastric Cancer

Early Gastric Cancer of the fundus

Early gastric cancer (EGC) is an adenocarcinoma confined to the mucosa or sub mucosa irrespective of lymph node involvement. The term “early” is related to primary lesion features and not to “early” detection. This histological entity, as defined in 1962 by the Japanese Society of Gastroenterological Endoscopy, was based on the observation that gastric cancer of this type had a favorable prognosis, with a five year survival greater than 90%.

Early Gastric Cancer of the fundus

The prognosis of gastric cancer is closely related to the stage of disease at diagnosis. Early gastric cancer, whereby disease is limited to mucosa and submucosa, confers a survival rate of greater than 90% in 5 years in many centres. Gastric cancer is still a major cause of cancer mortality worldwide.

Most patients with early gastric cancer present with symptoms indistinguishable from benign peptic ulcer disease. Screening for this group of patients improves detection rate of early gastric cancer and therefore its prognosis. Endoscopy for surveillance of premalignant lesions has been explored with this objective in mind. Serology testing for biomarkers such as pepsinogen, anti-Helicobacter pylori antibody and gastrin has been studied as an alternative to endoscopy. There is compelling evidence for the role of H. pylori in the initiation of Correa's cascade (stepwise progression from chronic active gastritis, atrophic gastritis, intestinal metaplasia, dysplasia and finally adenocarcinoma). Regression of premalignant lesions has been demonstrated with H. pylori eradication. However, it is not known whether this might effectively prevent gastric cancer in either low or high-risk population.

 


 

Endoscopic Mucosectomy

Endoscopic Mucosectomy Submucosal injection solution

 Injection of physiological saline;

This technique uses a combination of submucosal injection, aspiration of tissue into a clear soft plastic cap attached to the tip of the endoscope, and snare excision. [78]

Various single-use devices that include a combination of cap and specially designed snare are commercially available. Typically, the snare is opened within the distal internal rim of the cap, tissue is aspirated within the cap and snare, the snare is closed around the captured tissue, and a standard snare cautery is applied to excise the tissue. Caps are available in various sizes and have either a flat (cylindrical) or oblique end.

 

 

Endoscopic Mucosal Resection (EMR)

Video Endoscopic Sequence 5 of 14.

Aspiration of tissue during ligation-assisted endoscopic mucosal resection (EMR).

Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have provided new alternatives for minimally invasive treatment of gastrointestinal adenomas and early-stage cancers that involve a minimum risk of lymph-node metastasis. The use of submucosal injections is essential to the success of these endoscopic resection techniques. The “ideal” submucosal injection solution should provide a sufficiently high submucosal fluid cushion for safe and effective EMRs and ESDs while also preserving lesion tissue for accurate histopathological assessment. In the past, normal saline (NS) solution was commonly used for this purpose, but it is difficult to achieve the proper submucosal elevation and maintain the desired height with NS. Therefore, other safe and effective facilitative submucosal injection solutions have been developed that also take into account relevant cost-benefit considerations. This review examines recent advances in the development of effective submucosal injection solutions for use during endoscopic resections.

Endoscopic Mucosectomy

Endoscopic mucosectomy is a routine treatment mode for benign and malignant gastric lesions. The prognosis of patients with endoscopically treated early gastric cancer does not differ from patients subjected to surgical gastrectomy,

 


Endoscopic Mucosectomy

Video Endoscopic Sequence 7 of 14.

Various accessories and techniques are used. Mucosectomy snares are made of stiffer wire and designed to grasp flat tissue. A deeper plane of resection is achieved by using endoscopic suction or saline injection to lift the lesion-bearing mucosa. Fitting a transparent cap on the tip of the endoscope can enhance the lifting power of suction. The cap has a rim to hold an open mucosectomy snare.Mucosectomy can also be assisted by band ligation of tissue (analogous to variceal ligation). Other accessories include a ceramic ball-tipped needle knife to carve out extensive flat growths. Piecemeal resection technique allows the resection of a broad surface area, ensuring complete removal of the lesion.

We used rubber band ligation with the same bands that is used for of esophageal varices, which are sucked into a plastic hollow cylinder attached to the tip of the endoscope.The tissue is suctioned within the cylinder apparatus without infiltrating any solution.

In the simplest form of the procedure, a standard variceal band ligator device is used to aspirate the target lesion and apply a band around it (see the images below). After removal of the banding device, a separate snare is used to resect the lesion

Several session of ablative therapy was performed in order to overpass the cardias with the endoscope.

APC is a noncontact electrocoagulation device that useshigh-frequency monopolar current conducted to target tissuesthrough ionized argon gas (argon plasma). Electrons flow througha channel of electrically activated, ionized argon gas from theprobe electrode to the targeted tissue. Current density on arrivalat the tissue surface causes coagulation. Coagulation depth isdependent on generator power setting, flow rate of the argon gas,duration of application, and distance of the probe tip to thetarget tissue.

After the recanalization, We took advantage of introducedthe endoscope to the gastric camera and to apply morecoagulation to the tumor.The argon arc contacts tissue closest to the electrode allowing foren face or tangential coagulation. With thermal coagulation oftissue, a thin, superficial, electrically insulating zone of desiccationand a steam layer (from the boiling of tissue) result, bothcontributing to limit carbonization and depth of coagulation. Theinsulating zone of desiccation produces increased electricalresistance in the treated area. This prompts the current to moveto another point on the tissue surface where resistance islower. However, with prolonged application carbonization,vaporization, and deep tissue injury can occur.

Argon Plasma Coagulation, or APC for short, is a new
method of electrocoagulation. As a result, it allows for the
non-contact application of electrical energy to achieve
tissue destruction or hemostasis (the ability to stop
bleeding). APC uses high frequency electrical current
delivered via ionized argon gas. This gas, being
ionized, allows for the conduction of electricity, thus
leading to the term "argon plasma"

A mucosectomy is being performed.

Endoscopic mucosectomy is a treatment mode for benign
and malignant gastric lesions. The prognosis of patients
with endoscopically treated early gastric cancer does not
differ from patients subjected to surgical gastrectomy,
when the indications for endoscopic mucosectomy are
respected.


Video Endoscopic Sequence 4 of 11.

Saline dextrosa 50% and adrenalin 1/100.000 was injected
into the submucosa.

Traditionally, Barrett's esophagus was defined as the presence of columnar mucosa extending >/= 3 cm into the tubular esophagus. This definition has evolved into the presence of any specialized columnar epithelium in the esophagus as it became known that the presence of intestinal metaplasia of any length was associated with an increased risk of esophageal adenocarcinoma. Barrett's esophagus was simply referred to as short-segment (< 3 cm) or long-segment (>/= 3 cm). Even this definition became problematic when it was discovered that as many as 1 in 5 Barrett's esophagus patients have this specific epithelium in the region of an otherwise normal-appearing squamocolumnar junction (ie, intestinal metaplasia of the gastric cardia). While this latter lesion is of little clinical relevance (as neither dysplasia nor cancer occurs to be appreciably increased in that setting), cancer and dysplasia do occur in the more numerous short-segment Barrett's esophagus patients as well as the less commonly encountered long-segment Barrett's patients. While the long-segment patients likely have greater risk for neoplasia compared with the short-segment patients, the risk in short-segment cases is still increased over that of the general population. Whether surveillance exams should be at different intervals for these 2 classifications of Barrett's based on length is controversial, and current guidelines treat them identically.

Using endoscopic suction or saline injection to lift the lesion -bearing mucosa. Fitting a transparent cap on the tip of the endoscope can enhance the lifting power of suction. The cap has a rim to hold an open mucosectomy snare.

Endoscopic therapy has been employed for early-stage lesions in an attempt to avoid the high morbidity and mortality associated with current curative procedures such as esophagectomy.

Drawing up by Suction and Cutting This brings together several techniques which all necessi-tate drawing up the lesion by suction before the resection. This drawing by suction may be carried out with the aid of a plastic hood or of an elastic ligature unit.

Since the introduction of snare resection of pedunculated polyps (snare polypectomy) in the early 70's, many different devices and procedures were developed: strip-off biopsy, strip biopsy, with cap, and EMR with ligation.

After selecting appropriate cases by endoscopy, followed
if possible by endosonography, mucosectomy facilitates
complete histological analysis of the reselected tumor, and
makes it possible to determine precisely the quality
(curative or not) of the treatment carried out, in contrast to
destructive techniques (laser, dynamic phototherapy,
electrocoagulation).
