High Resolution Manometry versus Video Fluorography for Evaluating Dysphagia in Patients with Inflammatory Myopathy: A Pilot Study / 대한연하장애학회지

Objective@#Dysphagia has been reported to occur in patients with inflammatory myopathy (IM). Although high-resolution impedance manometry (HRIM) provides precise information regarding the pharyngeal pressure, it has not yet been used for assessing dysphagia in routine clinical practice. This study determined whether the results of HRIM for evaluating deglutition disorders in patients with IM could reflect an abnormality that can’t be identified by a video fluoroscopic swallowing study (VFSS). @*Methods@#We reviewed both VFSS and HRIM results of nine patients with IM, four of whom presented with globus sensation. @*Results@#Cricopharyngeal muscle dysfunction was noted in all four patients with globus sensation, and the upper esophageal sphincter residual pressure (UESRP) was higher (≥8 mmHg) in the patients with pharyngeal residue.Using VFSS and HRIM, we demonstrated that dysphagia in patients with IM may arise owing to failed relaxation of UES or decreased hyolaryngeal excursion. @*Conclusion@#In conclusion, UES-RP values of ≥8 mmHg indicate the presence of pharyngeal residue and globus sensation in patients with IM. HRIM provided a comprehensive assessment of the mechanisms of dysphagia, and HRIM facilitated recognizing subtle abnormalities in pharyngeal contraction and UES function. HRIM can overcome the limitations of VFSS by allowing clinicians to perform objective measurements in patients with IM.

Postpolypectomy Fever, a Rare Adverse Event of Polypectomy: Nested Case-Control Study

BACKGROUND/AIMS: Although postpolypectomy fever (PPF) without colon perforation or hemorrhage is rare, its incidence and risk factors have not been investigated. The objective of this study was to analyze the incidence and risk factors for PPF among inpatients. METHODS: Seven patients with PPF were matched with 70 patients without PPF from a total of 3,444 patients who underwent colonoscopic polypectomy. The PPF incidence during index hospitalization after colonoscopy was calculated, and univariate and multivariate analyses were performed to calculate the adjusted odds ratios (ORs) for risk factors. RESULTS: PPF without bleeding or perforation in the colon occurred in seven patients (0.2%). The median age was 58 years for cases and 61 years for controls. The median interval from polypectomy to occurrence of fever was 7 hours, and the median duration of fever was 9 hours. Polyp size >2 cm (adjusted OR, 1.08; 95% confidence interval [CI], 1.01 to 1.15; p=0.02) and hypertension (adjusted OR, 14.40; 95% CI, 1.23 to 180.87; p=0.03) were associated with a significantly increased risk of PPF. PPF increased the length of hospitalization. CONCLUSIONS: Although the crude incidence of PPF is low, PPF may prolong hospitalization. Risk factors for PPF include hypertension and large polyps.
