“…The sensitivity of the scintigraphic measurement of bolus transport to detect a manometrically proven oesophageal motor disorder has been reported to amount to 44% (Mughal et al 1986), 84% (Blackwell et al 1983) and 75% (De Caestecker et al 1986). The specificity, that is the percentage of asymptomatic individuals with normal oesophageal manometry having normal bolus transport, has been found to amount to 71% (Mughal et al 1986).…”

For the recognition and characterisation of oesophageal motor disorders, manometry represents the most reliable tool but yields no information on bolus transport. The transport can be quantitated by radionuclide techniques. The patient is positioned supine beneath a gamma-camera and instructed to swallow a radiolabelled bolus in a single gulp. Using a marker over the cricoid and the activity in the stomach as landmarks, regions of interest are drawn representing the upper, middle and lower third of the oesophagus and the gastric fundus. Activity-time curves enable one to recognise the clearance patterns in these regions. In combination, manometric and radionuclide transit studies recognise a higher number of motor disorders than either procedure alone. Radionuclide methods also are the most reliable and sensitive to quantitate gastric emptying. Procedure, meal size and composition as well as patient position must be standardised and correction techniques applied. The emptying of solid and liquid meal constituents can be evaluated concomitantly. Solids start to empty only after a lag phase of varying extent. With semi-solid meals, which are emptied at the same rate as solid meals of identical composition in the postlag phase, the recording time can be considerably shorter. Besides gastric emptying, the amplitude, frequency and propagation velocity of antral contractions can be recorded using serial images of short frame time and specially devised analytic techniques.

“…Several studies have compared the utility of esophageal scintigraphy to manometry to assess the value of scintigraphy as a diagnostic test [25][26][27][28]. There has been wide variation in the methodology of scintigraphy performed over the years (e.g., bolus consistency, volume and temperature of bolus, single or multiple swallows, imaging protocols, and data analysis), which may explain the sometimes conflicting results of these comparison studies.…”

The use of esophageal transit and gastric emptying studies in the evaluation of patients undergoing laparoscopic fundoplication

et al. 2010

Nuclear scintigraphic assessment of esophageal transit and gastric emptying are valuable, user-friendly tools to identify and avoid functional motility problems in the setting of fundoplication. These studies seem to be a reasonable alternative to manometry in assessing esophageal function before surgery in this setting. Postoperative symptoms may be related to objective changes in esophageal transit or gastric emptying. The causes may be iatrogenic in nature or related to vagal denervation with associated changes in esophagogastric compliance. Awareness of these physiologic changes may prompt further technical precautions at the time of surgery to avoid vagal injury and also may facilitate postoperative medical management.

The route of reconstruction following esophagectomy.Retrosternal reconstruction shows an increased rate of postoperative non-surgical complications and a slightly increased mortality compared to posterior mediastinal reconstruction. Radionuclid transit through the gastric tube is significantly longer in either way of reconstruction compared to normal controls. Tracerretention is significantly increased after retrosternal reconstruction. This however has no impact on the patients' quality of life. We therefore recommend posterior mediastinal reconstruction provided that curative resection is definitely achieved in order to avoid possible complications by local recurrence. In the palliative situation we would rather choose the retrosternal route of reconstruction as the functional disadvantages had no negative effect on quality of life and the general disadvantages seem to be neglectable in this situation. The same is true if adjuvant radiation of the tumorbed is planned. Pyloroplasty in our opinion is unnecessary. The presternal route of reconstruction is underrepresented in the literature. In our experience it has no indication.
