Treatment of supragastric belching with cognitive behavioral therapy improves quality of life and reduces acid gastroesophageal reflux.

OBJECTIVES: Excessive supragastric belching (SGB) manifests as troublesome belching, and can be associated with reflux and significant impact on quality of life (QOL). In some GERD patients, SGB-associated reflux contributes to up to 1/3 of the total esophageal acid exposure. We hypothesized that a cognitive-behavioral intervention (CBT) might reduce SGB, improve QOL, and reduce acid gastroesophageal reflux (GOR). We aimed to assess the effectiveness of CBT in patients with pathological SGB. METHODS: Patients with SGB were recruited at the Royal London Hospital. Patients attended CBT sessions focused on recognition of warning signals and preventative exercises. Objective outcomes were the number of SGBs, esophageal acid exposure time (AET), and proportion of AET related to SGBs. Subjective evaluation was by patient-reported questionnaires. RESULTS: Of 51 patients who started treatment, 39 completed the protocol, of whom 31 had a follow-up MII-pH study. The mean number of SGBs decreased significantly after CBT (before: 116 (47-323) vs. after 45 (22-139), P<0.0003). Sixteen of 31 patients were shown to have a reduction in SGB by >50%. In patients with increased AET at baseline, AET after CBT was decreased: 9.0-6.1% (P=0.005). Mean visual analog scale severity scores decreased after CBT (before: 260 (210-320) mm vs. after: 140 (80-210) mm, P<0.0001). CONCLUSIONS: Cognitive behavioral therapy reduced the number of SGB and improved social and daily activities. Careful analysis of MII-pH allows identification of a subgroup of GERD patients with acid reflux predominantly driven by SGB. In these patients, CBT can reduce esophageal acid exposure.

Clinical utility of the solid meal test during high-resolution esophageal manometry. A study in a Latin American population.

INTRODUCTION AND AIMS: The solid test meal (STM) is a challenge test that is done during esophageal manometry and appears to increase the diagnostic yield of the study. The aim of our analysis was to establish the normal values for STM and evaluate its clinical utility in a group of Latin American patients with esophageal disorders versus healthy controls. MATERIAL AND METHODS: A cross-sectional study was conducted on a group of healthy controls and consecutive patients that underwent high-resolution esophageal manometry, in which STM was done at the final part of the study and consisted of asking the subjects to eat 200 g of precooked rice. The results were compared during the conventional protocol and the STM. RESULTS: Twenty-five controls and 93 patients were evaluated. The majority of the controls (92%) completed the test in under 8 min. The STM changed the manometric diagnosis in 38% of the cases. The STM diagnosed 21% more major motor disorders than the conventional protocol; it doubled the cases of esophageal spasm and quadrupled the cases of jackhammer esophagus, whereas it demonstrated normal esophageal peristalsis in 43% of the cases with a previous diagnosis of ineffective esophageal motility. CONCLUSIONS: Our study confirms the fact that complementary STM during esophageal manometry adds information and enables a more physiologic assessment of esophageal motor function to be made, compared with liquid swallows, in patients with esophageal motor disorders.

[Cerebellopontine angle and internal auditory canal lipomas: report of four cases and review of the literature]. / Lipomas de angulo pontocerebeloso y conducto auditivo interno: serie de 4 casos clínicos y revisión de la literatura.

AIM: Lipomas are exceptional tumors at the Cerebellopontine Angle (CPA) or the Internal Auditory Canal (IAC). We evaluate clinical, histological and radiological characteristics of the cases diagnosed in our Hospital and the results of conservative versus surgical treatment. MATERIAL AND METHODS: We report 4 cases of CPA and/or IAC and review 99 previously reported in the literature. RESULTS: Unilateral tinnitus was the most frequent symptom (100%). All lesions showed hyperintensity on T1 and hypo/isointensity on T2--weighted MNR images. Two patients underwent a retro-sigmoidal approach without complete tumoral resection and with additional neurological consequences. Another two cases were followed up by annual MNRs. During the follow-up period (4.2 years average), neither clinical nor radiological changes were detected. CONCLUSION: The surgical resection of CPA y/o IAC lipomas is associated to a significant morbidity due to the high vascularization and the dense adherence of these lesions to the surrounding tissues. The MNR is the suitable technique for differential diagnosis between lesions at this location.
