Experimental: RAMPS group
Radical antegrade modular pancreatosplenectomy (RAMPS) includes the following aspects.
Firstly, the surgical approach is "antegrade", which means from the right to the left, the pancreatic neck will be transected at first and the spleen will be seperated at last.
Secondly, lymph nodes dissection includes not only the regional lymph nodes(No.10,11,18
lymph nodes), but also N1 station lymph nodes (N1: 6, 8a, 8p, 12a2/b2/p2, 13a/b, 14b/c/d, 14v, 17a/b), No.7, 9 lymph nodes, the lymph nodes anterior and left of superior mesenteric artery, as well as the peripheral nerve of celiac trunk.
Thirdly, the transection platform is in the pancreatic neck, which is mandatory.
At last, left prerenal fascia will be resected.
When the tumor abuts or infiltrates the left adrenal gland, left adrenalectomy will be performed, which is also called "posterior approach RAMPS".
While in normal cases, left adrenal gland will be preserved.

Active Comparator: SRPS group
Standard retrograde pancreatosplenectomy(SRPS) includes several key points.
Firstly, the surgical approach is "retrograde", which means from the left to the right, spleen will be seperated at first and the pancreas will be transected later on.
Secondly, only the regional lymph nodes will be dissected, which include No.10, No.11, No.18 lymph nodes, and No.9 lymph nodes should be dissected only when the lesion is in pancreatic neck.
Thirdly, the transection platform is in the left side of the lesion, but transection at pancreatic neck is not mandatory.
At last, the surgical plane is anterior to the left renal fascia, prerenal fascia will be preserved.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Overall survival
Time Frame: 21 months
|
Overall survival was defined as the time from surgery to either death or last follow-up.
Patients will be observed or contacted every 2 months in the first 2 years after surgery and then every 3 months thereafter.
Overall survival measurement will be based on patient's survival status and what is the date of death if the patient is not alive.

21 months

Measure Description |
Time Frame |
|---|---|---|
|
Disease free survival
Time Frame: 11 months
|
DFS was calculated from the date of surgery to the date of recurrence or last follow-up if recurrence did not occur.
Recurrence was diagnosed by imaging examination like CT, MRI, PET-CT and PET-MRI.
|
11 months
|
|
R0 resection rate
Time Frame: 1 month
|
R0 resection was defined as absence of malignant cells within 1 mm from the resection margin using the Royal College of Pathologists definition.
The assessment of the margin status will be done by pathologists.
|
1 month
|
|
retrieved lymph nodes
Time Frame: 1 month
|
The dissected lymph nodes will be sent to pathology department and the pathologists will separate the lymph nodes and give reports about how many lymph nodes are found and if the lymph nodes are positive or negative.
|
1 month
