The transoral, endoscopic route has been suggested as a possible approach for the correction of severe gastroesophageal reflux. Such a procedure would involve no mobilization of the cardia or other structures. The optimal placement, number, and configuration of sutures remains undefined.
With the use of a previously developed endoscopic sewing machine, this study was undertaken in baboons with two suture arrangements immediately below the lower esophageal sphincter. A linear arrangement (group I) and a circular arrangement (group II) were compared. During the 6 months after the procedure, the animals were evaluated using manometry, fluoroscopic barium swallow, upper gastrointestinal endoscopy, and a pressure volume test.
A significant increase in lower esophageal sphincter length was demonstrated only in group II (p = 0. 010). A significant increase in lower esophageal sphincter pressure was demonstrated only in group I animals (p = 0.008). The abdominal length increased in group I (p = 0.004) and group II (p = 0.004). The yield pressure and yield volume did not differ significantly from those measured previously in control animals. No evidence of reflux, stricture formation, esophagitis, or other pathology was noted.
Some manometric parameters associated with gastroesophageal reflux are altered by the endoscopic placement of sutures below the gastroesophageal junction, with no associated serious complications.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 March 2015.
All research outputs
#9,516,022
of 27,783,697 outputs
Outputs from Gastrointestinal Endoscopy
#4,101
of 7,919 outputs
Outputs of similar age
#16,595
of 46,443 outputs
Outputs of similar age from Gastrointestinal Endoscopy
#11
of 38 outputs
Altmetric has tracked 27,783,697 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,919 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.0. This one is in the 23rd percentile – i.e., 23% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 46,443 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 38 others from the same source and published within six weeks on either side of this one. This one is in the 2nd percentile – i.e., 2% of its contemporaries scored the same or lower than it.
