Insights
Downhill varices, though rare, pose a risk of life-threatening bleeding. This study analyzed 129 patients, highlighting the importance of understanding their causes and effective treatments like banding therapy.
Area of Science:
- Gastroenterology
- Vascular Medicine
Background:
- Downhill varices are often underestimated regarding their potential for severe bleeding complications.
- Understanding the risk factors and clinical presentation of downhill varices is crucial for patient management.
Purpose of the Study:
- To analyze the incidence, causes, and bleeding characteristics of downhill varices.
- To compare the bleeding risk between downhill and uphill varices.
- To draw attention to the potential severity of downhill varices.
Main Methods:
- Retrospective analysis of electronic endoscopy records from January 2004 to December 2012.
- Inclusion of 129 patients with identified downhill varices from 25,680 upper gastrointestinal endoscopies.
- Evaluation of primary endpoints: incidence, causes, bleeding type, and severity; secondary endpoints: varix size and bleeding risk comparison.
Main Results:
- Downhill varices were identified in 0.5% of patients (129 out of 25,680).
- Associated conditions included central venous catheter/port implantation (26), pacemaker history (22), pulmonary embolism (7), COPD (4), mediastinal tumors (2), and goiter (1).
- Vena cava superior syndrome was present in 62 patients.
Conclusions:
- Downhill varices have an incidence of 0.5% and can lead to fatal bleeding.
- Endoscopic banding therapy is a safe and effective treatment.
- Investigating the origin of severe downhill varices is essential for targeted therapy.
Aim:
Downhill varices are not so safe as thought and can lead to life-threating or mortal bleeding complication, even if rare. In order to draw attention to this topic, we analysed 129 patients.
Materials And Methods:
We evaluated the electronic endoscopy data records of all patients undergoing upper gastrointestinal endoscopy over a nine-year period from January 2004 till December 2012, within a retrospective approach. The primary endpoints, incidence, causes, kind of resulting upper gastrointestinal bleeding, and the severity of the bleeding were evaluated. Secondary endpoints were the evaluation of the size of downhill varices and a comparison of the risk of bleeding between downhill varices and uphill varices.
Results:
Downhill varices were identified, described, and/or documented in 129 patients of 25,680 upper gastrointestinal endoscopies. 26 patients had central venous catheter or port implantation, 22 patients had a history of an implantation of a cardiac pacemaker, 7 patients had severe pulmonary artery embolism, and 4 patients had severe chronic obstructive pulmonary disease. Two patients had mediastinal tumors, and one patient had a large retrosternal goiter as a possible cause of the vena cava syndrome. Altogether, 62 patients were related to a vena cava superior syndrome; 67 were not.
Conclusions:
Downhill varices can be seen with an incidence of 0.5%. Therapeutic means are the banding therapy as a safe and effective option. Severe bleedings associated with downhill varices can be mortal. Severe forms of downhill varices should be examined in relation to the origin in order to start a specific therapy.
