| Abstract |
Mechanical gastro-intestinal anastomosis using stapler is a critical step in laparoscopic Roux-en-Y gastric bypass (RYGB). To date the effect of the direction of staples on anastomotic leak has not been investigated. The study aim was to investigate the impact of the direction of staples on the integrity of the gastro-jejunal anastomosis. Eight gastro-jejunostomy (GJ) models were performed using porcine stomach and small intestine. Specimens were divided into group A where the cartridge was in the gastric lumen with the anvil in the jejunal lumen and vice versa in group B. Enterotomy was closed and gastric and jejunal ends were stapled off. Burst pressure (BP) was measured by infusion of methylene blue saline into the GJ model until leak occurred. Site of leak, BP, and total volume (TV) infused were recorded. Compliance (C) was calculated from the equation ΔTV/ΔBP. The BP was greater in group A compared to group B (18 mmHg (range 15-25) versus 11 mmHg (range 8-15); p = 0.045) despite similar TV between the groups 60.00 mL (range 55.00-65.00) versus 51.25 mL (range 40.00-60.00); p = 0.11). The compliance did not significantly differ between groups A and B (6.38 mL/mmHg (range 4.34-8.59) versus 5.61 mL/mmHg (range 3.93-7.21); p = 0.48). BP recorded when the stapler cartridge was introduced in the gastric lumen was higher than when it was introduced from the jejunal lumen. The lack of difference in compliance between groups suggests that the difference in BP was due to the difference in the direction of staples. |

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 03 May 2018.
All research outputs
#15,332,207
of 23,577,654 outputs
Outputs from Obesity Surgery
#2,055
of 3,471 outputs
Outputs of similar age
#198,765
of 327,764 outputs
Outputs of similar age from Obesity Surgery
#32
of 52 outputs
Altmetric has tracked 23,577,654 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,471 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.9. This one is in the 38th percentile – i.e., 38% 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 327,764 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 52 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
