“…As the majority of studies included heterogeneous patient groups, further risk factor assessment in these studies has been potentially confounded by the strong influence of ASA class. Therefore, specific risk factors in ASA class I and II patients are There are several possible mechanisms for hypoxemia during conscious sedation [20]. Most common mechanisms include hypoventilation due to depression of the respiratory drive by sedation and analgesic medications.…”

“…The presence of heterotopic gastric mucosa in the proximal esophagus can sometimes be shown by Tc 99 pertechnate injection and, more often, by radiography 24,25 . However, the most practical method is endoscopy and biopsy.…”

“…99m Tc-pertechnetate scintigraphy has been used to detect ectopic gastric mucosa, but its use has previously been confined to patients with a total thyroidectomy or those caking suppressive thyroid hormone supplements. In patients with a normal thyroid gland, there was overlapping activity between the uptake in the thyroid gland and the ectopic esophagea l mucosa, as both lie at the same level (22). As shown in Figure 3, using tomographic technique and three-dimensional reconstructi on we were able to demonstrate the patch of heterotopic gastric mucosa in our patient, even t hough it lay behind a normall y functioning thyroid gland.…”

The case of an elderly man with hete rotopic gastric mucosa of the ce rvical esophagus associated with an esophageal we b, as well as a d iscussion ofhete rotopic gastric mucosa, arc presented. T he presen ce of an ' inle t patch ' is a commo n e ndoscopic fi nd ing; about 10% of the population will have the hc tc ro to pic mucosa just below the upper esophagea l sphincter. Although th ere is controversy regardi ng pathogenesis, a congenital origin is fa voured over an acquired lesio n, The parc hes may be single, multiple or c irc umferentia l. His to logically, just over ha lf a rc ectopic gastric fu ndic mucosa a nd 90% of the pa tc hes conta in both parie ta l a nd c hief cells. Most patients with the inlet patch rema in asympto matic; about 15% w ith have mild pharyngeal d isco mfort and/or high dysphagia. Sympto ms will often accompa ny the deve lo pme nt of a comp lication, such as ulceration , that may be associated with bleeding, a stricture at the squamocolumnar junctio n o r an esophageal web. D iagnost ic manoeu vres to identify the mucosa include barium stud ies, endoscopy, Congo red sra ining to visua lize ac id production and nuclear medic ine scans. N o treatmen t is necessary unl ess complications develop. Compl ications can be treated successfu lly with H z blocke rs and/or e ndoscopic dilation. N o fo llow-up appears to be necessary as the re is no proof fo r malignan t transformation of the ecto pic mucosa.
