A review of oesophageal manometry testing in a district general hospital

摘要

Although several modalities are available to investigate oesophageal motility disorders, manometry is the gold standard. The procedure is increasingly available in district general hospitals but the clinical utility of this investigation in this setting remains unclear. The aim in this study was to evaluate the use and outcome of oesophageal manometry in a district general hospital. Data on 100 consecutive oesophageal manometry procedures were analysed, taking into account the referral pattern, indications, and results. The indications were gastro-oesophageal reflux disease (preoperative assessment before fundoplication) (58), dysphagia (28), chest pain (12), and epigastric pain (2). Diagnoses were made using predefined standard criteria and were as follows: normal (41), non-specific motility disorder (NSMD) (38), achalasia (15), diffuse oesophageal spasm (4), and scleroderma (2). Of the 58 patients who had undergone manometry as a preoperative assessment of oesophageal motility, 27 (47%) were abnormal. Twenty five (43%) had NSMD and two (3%) had achalasia. Forty eight of these preoperative cases were combined with 24 hour pH recording, which confirmed acid reflux in 35 (73%). The experience reported here reflects the published evidence that the use of manometry is changing. It is now more commonly used for assessment before antireflux surgery and for dysphagia, and the use in the assessment of chest pain is declining. The findings confirm the importance of eliminating achalasia before inappropriate antireflux surgery.
