background: there are controversies regarding the usefulness of the pyloric drainage methods after esophagectomy as well as differences among various pyloric drainage techniques. therefore, we compared the outcome of pyloromyotomy, pylorus buginage, and no intervention methods on gastric emptying among patients undergone esophagectomy. materials and methods: in this randomized clinical trial, p...

BACKGROUND There are controversies regarding the usefulness of the pyloric drainage methods after esophagectomy as well as differences among various pyloric drainage techniques. Therefore, we compared the outcome of pyloromyotomy, pylorus buginage, and no intervention methods on gastric emptying among patients undergone esophagectomy.

Endoscopic submucosal dissection (ESD) has been widely accepted as a curative treatment for gastric neoplasm. Pyloric stenosis is a chronic complication that can be caused by ESD. The aim of this study is to clarify the risk factors and management for pyloric stenosis. From January 2004 to January 2014, a total of 126 patients who underwent ESD adjacent to pylorus were reviewed retrospectively....

(This section is meant for residents to check their understanding regarding a particular topic) QUESTIONS 1. Discuss the epidemiology of pyloric atresia. 2. Describe the etiology of pyloric atresia. 3. What anomalies are associated with pyloric atresia? 4. Discuss the genetics of pyloric atresia. 5. How can pyloric atresia be antenatally diag-nosed? 6. What are clinical features of pyloric atre...

Cardiac sac network activity (cycle period tens of seconds to minutes) has long been known to alter pyloric network activity (cycle period approximately 1 s), but these effects have not been quantified. Some pyloric muscles extract cardiac sac timed variations in pyloric motor neuron firing, and consequently produce cardiac sac timed movements even though no cardiac sac neurons innervate them. ...

that given here, applies the term pyloric canal to the passage through the pyloric sphincter in X-ray photographs of the stomach (fig. 4) and in the description of the movements of the stomach. Most radiologists still use the terms pyloric antrum or pre-pyloric segment for what is anatomically the pyloric canal, though Shanks (1938) uses the terms pyloric canal and pylorus as synonymous, statin...

In several systems, including some well studied invertebrate "model" preparations, rapid, rhythmic inputs drive slow muscles. In this situation muscle contractions can summate temporally between motor neuron bursts, tonically contract, and low-pass filter broad-band input. We have investigated how the muscles innervated by each motor neuron type of the rapid, rhythmic (cycle period, approximate...

In the isolated stomatogastric nervous system of the lobster Fasus lalandii, the strong modifications of the pyloric motor pattern induced by firing of the single anterior pyloric modulator neurone (APM) are due primarily to modulation by APM activity of the regenerative membrane properties which are responsible for the 'burstiness' of all the pyloric neurones and particularly of the non-pacema...

The hyperpolarization-activated inward cationic current (Ih) is known to regulate the rhythmicity, excitability, and synaptic transmission in heart cells and many types of neurons across a variety of species, including some pyloric and gastric mill neurons in the stomatogastric ganglion (STG) in Cancer borealis and Panulirus interruptus However, little is known about the role of Ih in regulatin...
