Introduction:
The Angelchik prosthesis (AP) is a historic antireflux device which consists of a C-shaped silicone ring placed around the gastroesophageal junction (GEJ) and secured by Dacron tape. We present a rare experience with an AP and its impact on bariatric surgical outcomes.
Case:
Our patient is a 66-year-old woman who had an open antireflux procedure with an AP in 1987. She presented to a bariatric clinic for consideration of bariatric surgery for the treatment of morbid obesity and associated comorbidities. She also reported significant problems with reflux and dysphagia. After an appropriate work-up, an AP was identified at her GEJ. She was taken to the operating room for laparoscopic removal with planned interval laparoscopic sleeve gastrectomy. Intraoperatively, the AP was identified around the GEJ; after extensive adhesiolysis, the prosthesis was removed. Postoperatively, in order to determine if the AP had caused any lasting esophageal motility problems, the patient underwent a high-resolution esophageal manometry which demonstrated normal esophageal motility. Interval laparoscopic sleeve gastrectomy was performed safely 9 weeks later.
Conclusion:
Although rarely used, it is still possible to encounter an Angelchik prosthesis in practice. General and bariatric surgeons need to be aware of this rare device and understand how to manage its related complications.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Uncertainty: Confidence Intervals
Interpretation of Confidence Intervals
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...
Interval Level of Measurement
Data measured using the interval scale are similar to ordinal level data because they have a definite arrangement. However, in the interval level of measurement, the differences between data values are meaningful even though the data does not have a starting point.
Temperature is measured using the interval scale. It is measurable data, and the difference between...
