HPs are the kind of polyps seen most frequently among all benign gastric polyps and are generally smaller than 2 cm, singular, sessile or pedicled, frequently located in the antrum but can be seen in all gastric localizations (6).
Papillae anales slightly narrow with some short satae; apophyses posteriores very slender, apophyses posteriores 2.02 times longer than apophyses anteriores; apophyses anteriores relatively thick; antrum well developed; ductus bursae narrow and relatively short; corpus bursae slightly long.
A radial incision starting at 1 O'clock on right ear and 11 O'clock on left ear drawn laterally towards incisura terminalis a nd soft tissues retracted after adequate mastoid bone exposure: Endaural extension was used for C2a (Posterior extension to the antrum and mastoid) lesions.
In the conventional group, the antral cross-section was monitored through ultrasonography to determine whether the tube entered the antrum based on the tube sound shadow.
For histological analysis 5 gastric biopsy specimens were collected, 2 from the corpus (one from the lesser curvature and one from the greater curvature), 2 from the gastric antrum (one from the distal lesser curvature and one from the area next to the incisura angularis and one from the distal greater curvature).
Also, we used a hanging suture between the gastric pouch and the afferent loop to minimize reflux and a retaining suture between the lower part of the pouch and the antrum to prevent it from twisting.
Functionally, the sleeve was divided into a passive sleeve and an accelerated antrum. The patients demonstrated a rapid gastroduodenal transit time.
Double contrast-enhanced abdominopelvic CT scan was performed and revealed a hypodense mass along the anterior wall of the gastric antrum with subsequent pyloric stenosis and luminal obstruction with gastric dilatation in the body and fundus (Figure 1).
A cone beam CT was performed to provide a 3D detailed location of the appliance (Figures 2(a) and 2(b)) and confirmed it to be located outside the maxillary antrum.
Biopsies of the gastric antrum and duodenum revealed increased apoptotic cells and were consistent with acute gastric and duodenal GVHD.
A large, 8 x 5 cm in size, multilobed polypoid gastric mass situated in the antrum was found in gastroscopy.
