Gastroesophageal reflux disease: key messages for clinicians

Esophageal rupture after Heimlich maneuver: a case report and literature review

The Heimlich maneuver (HM) is lifesaving in a patient choked by a foreign body. It is safe and effective and does not require specific instruments. Nevertheless, rare severe complications have been reported, such as traumatic injury of the gastrointestinal tract, pneumomediastinum, rib fracture, diaphragm rupture, acute thrombosis of abdominal aortic aneurysm and mesenteric laceration. Abdominal injuries are the most common complications, especially esophageal and gastric wall rupture. This anatomic site is the most common location of organ injuries, in consequence of the main target of the force generated by the HM. Furthermore, the execution of HM by an untrained person may increase the risk for possible serious complications. Usually, HM complications are treated surgically, but based on clinical conditions, a conservative approach is possible. In our report, we described a case of esophageal rupture after a forceful HM, and we made a brief revision of literature concerning HM complications. We have also assessed the correlation between HM complications, abuse of non-steroidal anti-inflammatory drugs and the execution of the abdominal thrusts by untrained rescuers.

Can esophageal symptoms be associated with sleep disorders in esophageal rare diseases? A prospective case-control study across achalasia, eosinophilic esophagitis and gastroesophageal reflux disease

BACKGROUND

The association between sleep disorders and gastroesophageal reflux disease (GERD) has been the subject of several studies; however, quality of sleep has been under investigated in adult patients with eosinophilic esophagitis (EoE) and achalasia (Ach). This study aims to evaluate the prevalence of sleep disturbances in patients with EoE and Ach compared to GERD patients and their associations with esophageal symptoms.

METHODS

Thirty Ach patients and 20 EoE patients were consecutively enrolled and compared to a control group of 46 GERD patients. All patients underwent a standardized questionnaire investigating the intensity-frequency scores (from 0 to 6) of esophageal symptoms, Pittsburgh Sleep Quality Index (PSQI) questionnaire to assess sleep quality, a SF-36 survey to investigate health-related quality of life (both physical (PCS) and mental (MCS) component scales), Beck Depression Inventory-II (BDI-II) and State Trait Anxiety Inventory (STAI) to assess the presence of depression and anxiety.

RESULTS

The prevalence of sleep disturbances was 66.7% in Ach, 50% in EoE, and 60% in GERD patients (P=0.5). PCS and MCS significantly correlated with depression and anxiety levels. Ach patients showed significantly higher intensity-frequency scores of dysphagia for solids (Scheffè P<0.001) and liquids (Scheffè P<0.001) than EoE and GERD patients. No differences were found in the intensity-frequency scores of the esophageal symptoms among the three groups. There was a significant association between worst quality of sleep and higher intensity-frequency scores of regurgitation.

CONCLUSIONS

Sleep disturbances are common with Ach and EoE, similar to GERD patients. Moreover, there is a significant association between regurgitation, a typical GERD symptom, and poor quality of sleep, independent from diagnosis.

Diagnostic value of reflux episodes in gastroesophageal reflux-induced chronic cough: a novel predictive indicator

Background

Multichannel intraluminal impedance and pH-monitoring (MII-pH) is an essential testing modality for gastroesophageal reflux-induced chronic cough (GERC), while the existing diagnostic criteria still have some inherent defects. This study aimed to explore the diagnostic value of a direct and objective index, reflux episodes, and related parameters in MII-pH in different types of GERC.

Methods

Patients with chronic cough suspected of gastroesophageal reflux disease who successfully received MII-pH were enrolled. The differences in MII-pH parameters were analyzed among patients with different etiologies and the predictive diagnostic value of reflux episodes and related parameters were analyzed in patients with GERC, acid GERC, and non-acid GERC, and compared with existing diagnostic criteria.

Results

A total of 190 patients with suspected GERC who underwent MII-pH were enrolled; 131 of these patients were finally diagnosed with GERC. When the reflux episodes were used to diagnose GERC, the area under the curve (AUC) was 0.684; when the acid reflux episodes and the ratio of acid reflux episodes were used to diagnose acid GERC, the AUCs were 0.769 and 0.854; when the non-acid reflux episodes and the ratio of non-acid reflux episodes were used to diagnose non-acid GERC, the AUCs were 0.735 and 0.705, respectively. When the non-acid reflux episodes > 58 and the proportion of non-acid reflux episodes > 68.18% were used alone or in combination to diagnose non-acid GERC, their diagnostic value was significantly better than SAP or SI (all ps < 0.05).

Conclusion

The number of reflux episodes has a good diagnostic value for GERC, especially in the diagnosis of non-acid GERC.
