- Using simultaneous manometry and cineradiography, oesophageal evacuation was studied while contrast medium was infused via a catheter. The distal half of the oesophagus could be filled with contrast medium without triggering peristalsis. The hydrostatic pressure necessary to open the lower oesophageal sphincter (LES) was of approximately the same magnitude as the pressure gradient between oesophagus and LES. No significant relaxation of the LES could be observed at the initiation of swallowing. The LES may be looked upon not only as a sphincter preventing reflux but also as a gate which must be forced open by food.

- In 149 patients, a standardized radiologic method for the detection of gastro-oesophageal reflux was applied and compared with the results obtained at endoscopy and by a manometric reflux test. Radiologic reflux was recorded in 53 patients, of whom 25 had reflux without abdominal compression and 51 with compression. At least one of the other two types of examination disclosed pathologic conditions in all but 2 of 53 patients. Oesophagitis was significantly more severe among the patients with reflux observed at radiography. The presence of hiatal incompetence with reflux only to the hiatal hernia but not to the oesophagus was not a strong indicator of gastro-oesophageal reflux disease. Hiatal hernia was present in a significantly larger number of the patients with reflux at radiography than in those without reflux. Increased width of the hiatus gave stronger evidence for reflux disease than in patients with a normal hiatus. Thus, the width of the hiatus also had a bearing on the diagnosis of gastro-oesophageal reflux disease.

- The aim of the study was to ascertain whether abdominal compression by a standardized technique increases the reliability of the radiologic diagnosis of gastro-oesophageal reflux. Eighty-eight patients were examined by means of a manometric reflux test, 24-hour measurements of pH and endoscopy. The radiologic examination was performed with and without graded abdominal compression, the patient at the same time turning from side to side. When abdominal compression was included the result of the radiologic examination was positive in 31 patients. In the absence of abdominal compression reflux was detected in 11 of these patients. In one patient reflux was detected only without compression. All these 31 patients had one more test positive and in 27 at least 2 more tests were positive. Another 21 patients had reflux disease as indicated by at least 2 of the 3 other tests. The compression technique seems to yield no false positive responses, and proved to be significantly more reliable than examinations without compression.

Radiologic Diagnosis of Gastro-Oesophageal Reflux - Comparison of barium and low-density contrast medium
- 1987

Tidskriftsartikel (refereegranskat)abstract
- It has been proposed that the high density of ordinary barium suspensions may complicate the radiologic diagnosis of gastro-oesophageal reflux. For this reason P-contrast was developed (Ferring AB); a contrast medium with the same density as water (1 g/cm3). A comparison of P-contrast and barium (Mixobar Ventrikel 400 mg/ml) was performed in 82 patients. All patients were examined with both contrast media and the findings were compared with those at reflux test at manometry, endoscopy and 24-hour pH monitoring. Another 40 patients and 15 symptom-free controls were examined with two different amounts of barium, 100 ml and 200 ml, to study if the radiologic diagnosis of reflux varied with the volume of contrast medium administered. P-contrast was found to have no advantages over barium for the diagnosis of gastro-oesophageal reflux. The outcome of the radiologic examination was not influenced by the different volumes of barium used.

Radiologic findings after fundoplication compared with a pH reflux test and symptoms
- 1986

Tidskriftsartikel (refereegranskat)abstract
- In a follow-up after fundoplication, 61 patients underwent a double contrast examination of the stomach and a radiologic examination to detect any gastro-oesophageal reflux. The radiologic findings were compared with pH reflux test and symptoms. Gastro-oesophageal reflux was found in 7 patients at radiologic examination. None of these patients had an adequate fundoplication at a double contrast examination of the stomach and all had symptoms indicating reflux. Recurrence of gastro-oesophageal reflux may be shown at the radiologic examination and predicted by the morphologic appearances at the double contrast examination.

Esophageal function, radiography, and dysphagia in Sjögren's syndrome

- Esophageal function and anatomy were investigated with manometry, acid perfusion test, acid clearing test, and x-ray in 11 patients with primary Sjögren's syndrom (SS) and in 11 with secondary SS. The manometric investigation revealed minor motor differences in the SS patients as compared to 16 controls, ie, shorter peristaltic contraction time of the whole esophagus, and faster peristaltic velocity preferably in the distal part of the esophagus, while the results from the reflux tests did not differ between patients and controls. Radiographic examination revealed upper esophageal webs in 10% (2/20), and hiatal hernia in 25% (5/20). The dysphagia as reported by 73% of the patients cannot be explained by webs or impaired motor function and is regarded to be secondary to lack of saliva, making the solid bolus passage difficult.

Scintigraphy, radiography, and acid clearing in dysphagia patients after anti-reflux surgery

- Oesophageal emptying was studied with scintigraphy, radiography, and the acid clearing test (ACT) in 18 patients reporting dysphagia and previously operated on with fundoplication. Radiography with contrast medium, isodense with water, revealed abnormalities in either motility or emptying capacity in 39% (7/18). A A barium meal showed abnormalities--that is, a tight repair, disruption of the fundoplication, or recurrence of the hernia--in 56% (10/18). The ACT was prolonged in 40% (6/15) of the patients. Pathological findings at scintigraphy with a solid bolus were found in 67% (12/18). Even if scintigraphy with a solid bolus is the method that identifies the highest number of patients with impaired oesophageal function among the tests used, it cannot differentiate between functional and anatomical disorders. A barium meal examination is the method of choice when an anatomical disorder is suspected.
