| Abstract |
Laparoscopic sleeve gastrectomy (LSG) modifies the upper gastrointestinal tract motility. Controversial data currently exist. The aim of the study was to evaluate esophageal motility before and after LSG. Morbid obese patients scheduled for LSG underwent reflux symptoms evaluation and manometry preoperatively and postoperatively. The preoperative and postoperative results were compared and analyzed. Eighteen patients were enrolled. Heartburn and regurgitation improved in 38.9% and 11.1% of the patients, but deteriorated in 11.1% and 27.8% of the patients, respectively. Lower esophageal sphincter (LES) total length decreased postoperatively (p=0.002). Resting and residual pressures tended to decrease postoperatively (mean difference [95% confidence interval]: -4 [-8.3/0.2] mmHg, p=0.060; -1.4 [-3/0.1] mmHg, p=0.071, respectively). Amplitude pressure decreased from 95.7±37.3 to 69.8±26.3 mmHg at the upper border of LES (p=0.014), and tended to decrease at the distal esophagus from 128.5±30.1 to 112.1±35.4 mmHg (p=0.06) and mid-esophagus from 72.7±34.5 to 49.4±16.7 mmHg (p=0.006). Peristaltic normal swallow percentage increased from 47.2±36.8 to 82.8±28% (p=0.003). Postoperative regurgitation was strongly negatively correlated with LES total length (Spearman's r=-0.670). When groups were compared according to heartburn status, statistical significance was observed between the groups of improvement and deterioration regarding postoperative residual pressure and postoperative relaxation (p<0.002, p<0.002, respectively). With regard to regurgitation status, there was statistically significant difference between groups regarding preoperative amplitude pressure at the upper border of LES (p<0.056). Patients developed decreased LES length and weakened LES pressure after LSG. Esophageal body peristalsis was also affected in terms of decreased amplitude pressure, especially at the upper border of LES. Nevertheless, body peristalsis was normalized postoperatively. LSG might not deteriorate heartburn. Regurgitation might increase following LSG due to shortening of LES length, particularly in patients with range of preoperative amplitude pressure at the upper border of LES of 38.9-92.6 mmHg. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 22 July 2017.
All research outputs
#14,356,760
of 22,990,068 outputs
Outputs from Clinical and Experimental Gastroenterology
#155
of 307 outputs
Outputs of similar age
#175,438
of 314,061 outputs
Outputs of similar age from Clinical and Experimental Gastroenterology
#4
of 9 outputs
Altmetric has tracked 22,990,068 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 307 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one is in the 44th percentile – i.e., 44% 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 314,061 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
