Summary
Complications are common after laparoscopic adjustable gastric banding (LAGB). CT scans revealed that 43% of patients had complications, with many found incidentally and some being clinically significant.
Area of Science:
- Radiology
- Gastroenterology
- Bariatric Surgery
Background:
- Laparoscopic adjustable gastric banding (LAGB) was a prevalent bariatric procedure.
- LAGB devices are frequently encountered on CT scans in clinical practice.
- Understanding LAGB-associated complications is crucial for accurate radiological interpretation.
Purpose of the Study:
- To determine the frequency of complications associated with LAGB.
- To describe the spectrum of LAGB complications observed on CT scans.
- To differentiate between symptomatic and incidental findings.
Main Methods:
- Retrospective review of CT scans for patients with LAGB.
- Search term 'band' used for identification between December 2011 and April 2017.
- Classification of complications as symptomatic or incidental based on clinical presentation.
Main Results:
- Complications were identified in 43.1% of 160 patients who underwent LAGB.
- Esophageal dilatation (29.4%) and pulmonary complications (8.2%) were most frequent.
- Over half of the identified complications (54.2%) were incidental, with 18% of these being clinically important.
Conclusions:
- LAGB complications are frequent, detected in nearly half of CT scans.
- A significant proportion of complications are incidentally found and can be clinically important.
- Radiologists must be aware of the spectrum of LAGB complications for accurate diagnosis.

17.2K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

01:16Gastric Motility
3.2K
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.

Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

844
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,...

01:16Gastric Emptying
3.8K
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...

01:26Gastric Phase of Digestion
3.4K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...
