Effect of Helicobacter pylori eradication on development of erosive esophagitis and gastroesophageal reflux disease symptoms: a post hoc analysis of eight double blind prospective studies

OBJECTIVES: The aim of this study was to assess the development of erosive esophagitis, the development of gastroesophageal reflux disease (GERD) symptoms in patients without prior symptomatic or endoscopic GERD, and the worsening of GERD symptoms in patients with prior symptomatic GERD in a post hoc analysis of eight double-blind prospective trials of Helicobacter pylori ( H. pylori) therapy in 1165 patients. METHODS: Patients with active or past duodenal ulcer and without baseline erosive esophagitis had end of study endoscopies 4–30 wk after completion of therapy. A total of 533 patients had heartburn and regurgitation scores assessed at baseline and 4 wk after end of therapy, and were divided into two groups: 1) no prior GERD symptoms (N = 127) and 2) prior GERD symptoms (N = 406). H. pylori was assessed at baseline and ≥4 wk after therapy by rapid urease test, histology, and culture. RESULTS: Erosive esophagitis developed in 24 (4%) of 621 patients with cure versus 14 (3%) of 544 with persistent H. pylori (OR = 1.52, 95% CI = 0.78–2.97). In the longest study (28–30-wk follow-up), esophagitis developed in two (7%) of 28 patients with cure versus five (7%) of 76 with persistent infection. New GERD symptoms developed in 13 (14%) of 92 patients with cure versus seven (20%) of 35 with persistent infection (OR = 0.66, 95% CI = 0.24–1.82). GERD worsened in 20 (7%) of 269 with cure vs 20 (15%) of 137 with persistent H. pylori (OR = 0.47, 95% CI = 0.24–0.91; p = 0.02). CONCLUSIONS: Our results do not support the hypothesis that H. pylori eradication in patients with duodenal ulcer disease leads to the development of erosive esophagitis, the development of new symptomatic GERD, or worsening of symptoms in patients with pre-existing GERD.

Barrett's esophagus: a surgical disease

Barrett's metaplasia can develop in patients with gastroesophageal reflux disease (GERD), and metaplasia can evolve into dysplasia and adenocarcinoma. The optimal treatment for Barrett's metaplasia and dysplasia is still being debated. The study reported herein was designed to assess the following: (1) the incidence of Barrett's metaplasia among patients with GERD; (2) the ability of laparoscopic fundoplication to control symptoms in patients with Barrett's metaplasia; (3) the results of esophagectomy in patients with high-grade dysplasia; and (4) the character of endoscopic follow-up programs of patients with Barrett's disease being managed by physicians throughout a large geographic region (northern California). Five-hundred thirty-five patients evaluated between October 1989 and February 1997 at the University of California San Francisco Swallowing Center had a diagnosis of GERD established by upper gastrointestinal series, endoscopy, manometry, and pH monitoring. Thirty-eight symptomatic patients with GERD and Barrett's metaplasia underwent laparoscopic fundoplication. Eleven other consecutive patients with high-grade dysplasia underwent transhiatal esophagectomies. Barrett's metaplasia was present in 72 (13%) of the 535 patients with GERD. The following results were achieved in patients who underwent laparoscopic fundoplication (n = 38): Heartburn resolved in 95% of patients, regurgitation in 93% of patients, and cough in 100% of patients. With regard to transhiatal esophagectomy (n = 11), the average duration of the operation was 339 ± 89 minutes. The only significant complications were two esophageal anastomotic leaks, both of which resolved without sequelae. Mean hospital stay was 14 ± 5 days. There were no deaths. The specimens showed high-grade dysplasia in seven patients and invasive adenocarcinoma (undiagnosed preoperatively) in four (36%). These results can be summarized as follows: (1) Barrett's metaplasia was present in 13% of patients with GERD being evaluated at a busy diagnostic center; (2) laparoscopic fundoplication was highly successful in controlling symptoms of GERD in patients with Barrett's metaplasia; (3) in patients with high-grade dysplasia esophagectomy was performed safely (invasive cancer had eluded preoperative endoscopic biopsies in one third of these patients); and (4) even though periodic endoscopic examination of Barrett's disease is universally recommended, this was actually done in fewer than two thirds of patients being managed by a large number of independent physicians in this geographic area.
