Issues and controversies in esophageal inlet patch

Table 1 Clinicopathologic classification of cervical heterotopic gastric mucosa (CHGM) proposed by von Rahden et al[7] and proposed management

CHGM I	Asymptomatic individuals with esophageal CHGM- reassurance of the patient+ optional follow up
CHGM II without morphologic changes	Symptomatic individuals with esophageal CHGM (globus sensation, cough, hoarseness or "extraesophageal manifestations")- reassurance and explain to the patient possible implication such as esophageal hypersensitivity+ acid suppression, prokinetic+ select cases to exclude H Pylori if persistence of symptoms+ endoscopic reevaluation in case of suspected complication of inlet patch
CHGM III	Inlet patch complications- endoscopic therapy (e.g., dilatation, argon plasma coagulation, radiofrequency ablation)
CHGM IV	Dysplasia within the inlet patch- endoscopic management (EMR, ESD)+ surveillance
CHGM V	Invasive cancer within the inlet patch- interdisciplinary team decision (gastroenterologist- oncologist- surgeon)
