| Abstract |
Most submucosal tumors (SMTs) in the esophagogastric junction (EGJ) are irregularly shaped and different from those in the esophagus, where submucosal tunneling endoscopic resection (STER) has been proven effective and safe. However, few reports paid attention to STER for SMTs in the EGJ. The aim of the study was not only to evaluate the effect of STER in patients with SMTs in the EGJ but to analyze the risk factors for failure of en bloc resection. A consecutive of 47 patients with SMTs originating from the muscularis propria (MP) layer in the EGJ underwent STER were retrospectively included between September 2012 and December 2016. Thirty-five tumors underwent en bloc resection, and the other 12 tumors received piecemeal resection. The tumor size, operation time, en bloc resection rate, complications, residual, and local recurrence were achieved and compared between the two groups. Forty-six of 47 lesions (97.9%) were successfully resected. The mean lesion size was 29.7 ± 16.3 mm. Both the en bloc resection rate and complete resection rate were 74.5% (35/47). No severe complications occurred in the 47 patients. Patients in the piecemeal resection group had more irregularly shaped lesions, longer tumor diameter, larger tumor size (≥40 mm), longer operation time, and longer hospital stay after procedure (P < 0.05), and there were no statistically differences between the two groups in in-operative complications, post-operative complications, and residual rate (P > 0.05). By univariate analysis and stepwise logistic regression analysis, irregular shape and tumor diameter ≥20 mm were two risk factors for failure of en bloc resection. STER is an effective and safe technique for the treatment of SMTs arising from the MP layer in the EGJ. Irregular shape and tumor diameter ≥20 mm are the reliable risk factors for en bloc resection failure. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 15 August 2017.
All research outputs
#18,567,744
of 22,997,544 outputs
Outputs from Surgical Endoscopy
#4,792
of 6,096 outputs
Outputs of similar age
#242,660
of 316,580 outputs
Outputs of similar age from Surgical Endoscopy
#120
of 144 outputs
Altmetric has tracked 22,997,544 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,096 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 6th percentile – i.e., 6% 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 316,580 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 144 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.
