Proton pump inhibitors and the time trends for esophageal dilation

Am J Gastroenterol. 2004 May;99(5):797-800. doi: 10.1111/j.1572-0241.2004.04169.x.

Abstract

Aim: Little is known about the impact of widespread proton pump inhibitor use on the need for dilation of esophageal strictures. To determine the time trends for upper endoscopy and stricture dilation before and after the availability of proton pump inhibitors.

Methods: The computerized databases of two large community hospitals were analyzed. Annual data on dilation procedures (by all methods) and upper endoscopy were obtained and analyzed in quartiles from 1986 to 2001 to determine if the relative or absolute need for dilation changed following the introduction of proton pump inhibitors in the United States. The number of prescriptions for acid suppressive agents (H2 receptor antagonists and proton pump inhibitors) for the corresponding time period was obtained from the IMS health database.

Results: A total of 57,496 upper GI endoscopies and 2,868 esophageal dilations were performed. The proportion of patients undergoing esophageal dilation increased from 4% in 1986-1989 to 6% in 1990-1993 (p < 0.001), remained unchanged (5.8%) in the period from 1994 to 1997 but declined significantly to 3.9% (p < 0.001) in the next quartile (1998-2001). Absolute numbers of dilation procedures declined significantly in the last quartile (1998-2001) and the proton pump inhibitor prescriptions in the United States increased markedly from 1995 onward.

Conclusions: The need for stricture dilation peaked in 1994 and has declined thereafter, corresponding to an increase in the use of proton pump inhibitors. The widespread use of proton pump inhibitors has not, however, abolished the need for esophageal dilation.
