Esophagogastric junction distensibility assessed using the functional lumen imaging probe

Figure 1 Flow chart of records identified through literature search and those excluded and included for analysis. Initial literature search identified 247 citations. After elimination of duplicate citations and abstract-only articles, 77 articles remained. The full-text articles of these 77 citations were reviewed and 19 studies met eligibility requirements for inclusion.

Figure 2 Healthy subjects. A: Mean values (open circles) with standard deviations (vertical boxes around means) and median values (closed circles) with 5^th to 95^th percentile (vertical boxes around medians), and ranges (vertical lines) for distensibility (mm²/mmHg) at FLIP bag volume of 30, 40, and 50 mL in healthy volunteers are shown in this plot; B: Mean values (open circles) with standard deviations (vertical boxes around means) and median values (closed circles) with 5^th to 95^th percentile (vertical boxes around medians), and ranges (vertical lines) for distensibility (mm²/mmHg) in GERD subjects before and after fundoplication are shown in this plot; C: Mean values (open circles) with standard deviations (vertical boxes around means) and median values (closed circles) with 5^th to 95^th percentile (vertical boxes around medians), and ranges (vertical lines) for distensibility (mm²/mmHg) in achalasia patients pre- and post-treatment using balloon length 7-10 cm at 40 mL bag volume are shown in this plot. The increase in EGJ distensibility post-achalasia treatment is illustrated here.
