Continuous esophageal pH monitoring during laparoscopic cholecystectomy
Surgical Endoscopy, 1994Gastro-esophageal regurgitation (GER) and eventual aspiration is considered a major risk during general anesthesia. High intraperitoneal pressure produced during laparoscopic cholecystectomy (LC) is a possible source of increased GER. We investigated the incidence of GER using continuous esophageal pH monitoring in 14 patients undergoing elective LC ...

The Reproducibility of Ambulatory Intra-Esophageal pH Monitoring [PDF]
, 1993 Prolonged intra-esophageal pH monitoring is regarded as the “gold standard” test for the diagnosis of abnormal gastro-esophageal reflux, with a reported sensitivity of 88% and specificity of 98% [1]. Its use has also been advocated in patients with atypical chest pain [2], lung disease [3], and to evaluate medical and surgical treatment [4]. Although a

Ambulatory esophageal pH monitoring using a wireless system
The American Journal of Gastroenterology, 2003Limitations of catheter-based esophageal pH monitoring are discomfort, inconvenience, and interference with normal activity. An alternative to conventional pH monitoring is the wireless Medtronic Bravo pH System. The aim of this study was to evaluate the safety, performance, and tolerability of this system.A total of 44 healthy subjects and 41 patients

Esophageal pH Monitoring of Postprandial Gastroesophageal Reflux
Digestive Diseases, 1993To analyze postprandial gastroesophageal reflux by means of ambulatory gastroesophageal pH monitoring for 24 h, four groups were studied prospectively: group A: 22 healthy volunteers; group B: 31 ...

Reproducibility of ambulatory esophageal pH monitoring in the aperistaltic esophagus
Dysphagia, 1996The reproducibility of ambulatory 24-h esophageal pH monitoring was evaluated in 16 consecutive patients by comparing the difference in two consecutive 24-h periods. The study group included 8 patients with scleroderma esophagus and 8 treated achalasia patients. The amount of reflux was expressed as the percentage of time the pH was < 4.0.

Ambulatory esophageal pH monitoring in children as an indicator for surgery
Journal of Pediatric Surgery, 1986Twenty-four-hour esophageal pH monitoring was performed in 59 children with symptoms of gastroesophageal reflux using a miniature pH electrode and a portable recording system to establish the diagnosis. Significant reflux was seen in 26 (44%) of the patients and these were treated for six weeks with cimetidine, Gaviscon, and Nestargel.

Evaluation of a new catheter for esophageal pH monitoring.
Hepato-gastroenterology, 1991A new catheter, provided with an Ion Sensitive Field Effect Transistor as a pH sensor and incorporating a reference electrode, was evaluated for esophageal pH recording. The pH-sensitivity was 54 mV/pH in vitro, with a linear response between pH 2 and pH 9.

A Small Flexible pH-Electrode for Esophageal Monitoring
1981A small flexible pH-electrode was developed for monitoring the esophageal pH of small infants (Fig. 1). The sensing part of the electrode consists of a 1.3 mm diameter pH glass hemisphere sealed onto a 1.3 mm glass tube. The total length of the glass electrode is 6 mm.
