Abstract

The study aims to investigate the clinicopathological features and surgical outcomes of neuroendocrine tumors of ampulla of Vater (NETAoVs) patients who underwent pancreaticoduodenectomy. From January 2007 to December 2014, 45 patients underwent pancreaticoduodenectomy for malignant disease of the ampulla of Vater in our institution. Of those, 5 patients were diagnosed as neuroendocrine tumors. The data included age, sex, presenting symptoms, preoperative imaging, preoperative type of biopsy results, type of operation, pathologic findings and survival status. The patient's mean age was 55.2 ± 9.7 years. Endoscopic ultrasound guided biopsy was performed in 4 patients and gastroduodenoscopic biopsy was performed in one patient. All showed neuroendocrine tumor without mitosis. Mean tumor size was 1.9 ± 0.56 cm (range, 1.2-2.0 cm). Lymph node metastases were detected in two patients. All patients were synaptophysin-positive. Median periods of follow-up were 45 months (range, 43-78 months). Recurrence after operation occurred in two patients. 4 patients were alive at the last follow-up. Radical resection for NETAoVs can provide the information of status of lymph node metastasis after surgery. However, correlation between lymph node metastasis and overall survival is uncertain to date.

Attention Score in Context

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 06 July 2017.
All research outputs
#15,467,628
of 22,985,065 outputs
Outputs from BMC Gastroenterology
#843
of 1,763 outputs
Outputs of similar age
#198,815
of 316,440 outputs
Outputs of similar age from BMC Gastroenterology
#5
of 17 outputs
Altmetric has tracked 22,985,065 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,763 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one is in the 40th percentile – i.e., 40% 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 316,440 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
