|November 15, 2018
Summary
Peroral endoscopic myotomy (POEM) for esophageal achalasia can cause complications like hypercapnia and perforation. However, these adverse events were successfully managed during the endoscopic procedure in this study.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- Esophageal achalasia is a motility disorder requiring intervention.
- Peroral endoscopic myotomy (POEM) is an established treatment for achalasia.
Purpose of the Study:
- To analyze complications associated with POEM in esophageal achalasia patients.
- To evaluate the management of these complications during the procedure.
Main Methods:
- Retrospective analysis of 27 patients undergoing POEM for achalasia.
- Documentation of intraprocedural complications.
Main Results:
- Identified complications included hypercapnia, capnoperitoneum, hemorrhage, and esophageal perforation.
- All noted complications were effectively suppressed during endoscopic manipulation.
Conclusions:
- POEM for esophageal achalasia is associated with specific, manageable complications.
- Endoscopic techniques allow for the successful suppression of adverse events during POEM.

Distance Corrections
290
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Power Factor Correction
539
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

Esophageal Varices-I: Introduction
1.5K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Hemodialysis II: Procedure and Complications
821
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Esophageal Perforation-I: Introduction
600
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Esophageal Strictures-I: Introduction
875
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
