Insights

Primary acquired gastric outlet obstruction (GOO) is rare in older children but presents with nonbilious vomiting. Surgical intervention, like gastrojejunostomy, offers a curative solution for this condition.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Clinical Case Series

Background:

  • Idiopathic hypertrophic pyloric stenosis is the most common cause of gastric outlet obstruction (GOO) in infants.
  • Late-onset pyloric stenosis beyond infancy is rare, and its etiology is poorly understood.

Purpose of the Study:

  • To report the experience of managing 5 cases of primary acquired GOO in older children.
  • To describe similarities and differences in management within this patient population.

Main Methods:

  • Retrospective single-center study.
  • Analysis of 5 patients with primary acquired GOO between July 2014 and June 2018.
  • Review of clinical presentation, diagnostic workup, and surgical outcomes.

Main Results:

  • Patients ranged from 3 to 6 years old, with one female.
  • All presented with recurrent, nonbilious vomiting and failure to thrive.
  • Diagnostic imaging showed a dilated stomach and delayed gastric emptying; surgery (retrocolic gastrojejunostomy) was curative in all cases.

Conclusions:

  • Primary acquired GOO should be considered in older children with nonbilious vomiting and failure to thrive.
  • Prompt surgical intervention is crucial for adequate nutrition and development.
  • Further research is needed to understand the pathophysiology and guide prevention/treatment.

Lattice Centering and Coordination Number

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

Upon food entry, the stomach initiates...

Center of Gravity

The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

Center of Gravity

The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

Center of Mass

The center of mass is the point at which the total mass of an object can be said to be concentrated. It is a fundamental principle in mechanics and physics that applies to all objects regardless of their shape or size. The center of gravity is the point at which an object’s weight appears to be concentrated and can be used to balance the object perfectly.
The knowledge of the center of mass can also help us to describe and predict the motion of objects. For example, when a ball is thrown...

Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
