Acid and bile reflux in erosive reflux disease, non-erosive reflux disease and Barrett's esophagus.

BACKGROUND/AIMS: Gastroesophageal reflux disease (GERD) may occur with acid, bile or in a mixed form. Endoscopic injury and mucosal metaplasia are a known sequlae to pathological GERD. The aim of the study was to determine the contribution of acid and duodenogastroesophageal reflux (DGER) to endoscopic severity in patients with GERD and Barrett's esophagus. METHODS: Ninety-one patients complaining of reflux symptoms were studied with upper gastrointestinal endoscopy and graded to non-erosive reflux disease (NERD), erosive reflux disease (ERD) and Barrett's esophagus (BE). Esophageal manometry and simultaneous ambulatory 24-h esophageal pH and bilirubin monitoring (Bilitec 2000) were done to all patients. RESULTS: Seventy one patients (78.0%) had ERD (Savary-Miller (grade I-III), 11 patients (12.1%) had NERD and 9 patients (9.9%) had BE suspected endoscopically and diagnosed by histological esophageal biopsy. Combined 24-h esophageal bilirubin and pH monitoring revealed that 39 patients (42.9%) had mixed acid and bile reflux, 16 (17.6%) had pathological acid reflux only, 18 (19.8%) had bile reflux only and 18 patients (19.8%) had no evidence of abnormal reflux. The percentage of the total time of bilirubin absorbance above 0.14, in 71 patients with ERD was (8.18 +/- 11.28%), and in 9 patients with BE was (15.48 +/- 30.48%) which was significantly greater than that in 11 patients with NERD (4.48 +/- 8.99%), p < 0.05 and p = 0.01 respectively. All BE patients had abnormal esophageal bile reflux (3 bile alone and 6 mixed bile and acid); 44 of 71 patients (61.97%) with ERD had abnormal esophageal bile reflux (13 bile alone and 31 mixed bile and acid); meanwhile 15 of them (21.2%) had abnormal acid exposure alone. Of the 11 patients with NERD, 4 patients (36.4%) had abnormal esophageal bile reflux, 2 of them mixed with acid. CONCLUSIONS: The Bilitec method reliably identifies the presence of bilirubin and quantitatively detects duodenogastroesophageal reflux of bile. Mixed reflux (acid and bile) is the chief pattern of reflux in GERD patients in this study. Bile reflux either alone or mixed with acid reflux contributes to the severity of erosive and non-erosive reflux disease as well as to Barrett's esophagus.

Quality of life and patient satisfaction 3 months and 3 years after laparoscopic Nissen's fundoplication.

BACKGROUND/AIM: This study is based on studying the quality of life and degree of satisfaction among gastroesophageal reflux disease (GERD) patients after Laparoscopic Nissen's fundoplication (LNF) operations. SUMMARY BACKGROUND DATA: A GERD patient is most interested in symptom relief, whereas his surgeon will also be interested in the improvement of anatomical and functional investigations. MATERIALS AND METHODS: One hundred patients with symptoms of GERD, adequate motility study and positive 24-hour pH studies underwent LNF in El-Mansoura Gastroenterology Center between 2002 and 2004. All patients completed the Gastroesophageal Reflux Disease-Health Related Quality Of Life (GERD-HRQL) questionnaire both pre- and postoperatively (early within 3 months after operation and late after 3 years). Furthermore, all patients were given a form with 4 grades (excellent, good, fair and poor) and they were requested to freely assess both the early and late clinical outcomes. RESULTS: There was statistically significant improvement in all the items of the GERD-HRQL questionnaire, both early and late (P < 0.001). With regard to patient satisfaction; only 58 cases showed excellent clinical satisfaction early postoperatively, while 29, 8 and 5 patients showed good, fair and poor responses, respectively. These figures improved on late followup (P < 0.05), i.e., 76 excellent, 16 good and 8 fair results. CONCLUSIONS: LNF improves all the items of quality of life among GERD patients significantly (P < 0.001). Patient satisfaction after LNF improves with time; 58 cases showed early postoperative excellent clinical satisfaction as compared to 76 late cases (P < 0.05). However, LNF may not be the standard management of reflux symptoms, particularly from some patients' perspective.
