As these instances are exceedingly rare, these lesions need not require endoscopic surveillance or removal once definitively diagnosed. This is why they are often diagnosed on routine mucosal biopsy sampling at the time of an index EGD or colonoscopy. Type III gastric carcinoid tumors are the sporadic form and are not associated with high gastrin levels. Intermediate-sized GCTs of 1—2 cm may undergo annual surveillance, or possibly endoscopic resection provided the lesion does not penetrate deeper than the submucosal layer on EUS evaluation. However, there are challenging aspects in EUS of the stomach, especially in the prepyloric region and the gastric angle where maintaining the water level and the probe scanning perpendicular to the wall can sometimes be hard to achieve. The latter together with their esophageal counterparts may correlate with the risk of variceal bleeding[ 34 ]. For larger lesions, surgical resection seems to be the best alternative; 2 Extrinsic compressions: Compressions on the gastric wall from organs neighboring the stomach may occasionally present as SMLs and sometimes can cause diagnostic problems. A thickening of the gastric wall layers, as well as the presence of gastric or paragastric collateral varises may also be seen[ 123234 ].

    Therefore once definitively diagnosed, they do not require regular endoscopic surveillance. Alternatively, these lesions may also be referred for surgical resection, including some minimally invasive transanal resection techniques.

    Such a technique will help depict the full extent of the lesion and its relation to neighboring organs and structures. Once resected, follow-up endoscopies are recommended at 6 and 12 months after therapy as per NCCN guidelines [ Kulke et al.

    This should be followed by careful inspection and determination of the size and shape of the lesion, the regularity of its borders, its echogenic characteristsics, presence of vessels facilitated by the Doppler-imaging possibilities of modern electronic echoendoscopes. They produce a high-resolution image in the near field with limited penetration depth, which ranges from to cm, depending of the ultrasound frequency used.

EUS has also found a role in the treatment and follow up of esophageal and gastric varices[ 1232 ]. They mostly arise from within the submucosal layer of the GI tract wall and grow towards the mucosa, often making it feasible to obtain a definitive diagnose by means of standard biopsy with a regular forceps.

The third, echo-rich, layer corresponds to the submucosa, the fourth echo-poor to the muscularis propria, and the fifth echo-rich to the serosa, which is usually not easily distinguishable from the surrounding echo-rich tissue. Endoscopically, they frequently display a central area of umbilication within the center of the lesion as seen in Figure 3b.
