About

To investigate the clinical efficacy and safety of laparoscopic bursectomy and D2 lymphadenectomy (LBDL group) versus laparoscopic D2 lymphadenectomy (LDL group) in advanced gastric cancer by prospective randomized controlled clinical trial.

Full description

To compare the LBDL group and LDL group in the advanced gastric cancer. A prospective randomized controlled trial will be performed in the GI department, Guangdong provincial hospital of Chinese Medicine from November 2016 to November 2024. The sample size，100 cases with advanced gastric cancer, will be needed after calculated by the statistics. The 100 cases will be randomly divided into two groups: LBDL group and LDL group. Primary outcomes are the 3 years' Disease-free survival (DFS) rate, The secondary outcomes are the 3 years' and 5 years' Disease-free survival (DFS) rate, the 3 years and 5 years Overall survival（OS）rate, operative time, the total blood loss, the intra-operative complication and the post-operative complication, the number of lymph nodes dissected, the number of conversion to open laparotomy, and the other outcomes are the average time of ground activities, the hospital stay. The data in two groups will be compared.

100 participants in 2 patient groups

The bursectomy and D2 lymphadenectomy

Experimental group

Description:

Laparoscopic bursectomy and D2 lymphadenectomy will be performed for the treatment of patients assigned to this group.The key of this approach are that anterior lobe of transverse mesocolon and capsula pancreatis will be dissected with the D2 lymphadenectomy according to the guidelines of National Comprehensive Cancer Network(NCCN)

Treatment:

Procedure: Laparoscopic bursectomy and D2 lymphadenectomy

The D2 lymphadenectomy

Active Comparator group

Description:

Laparoscopic D2 lymphadenectomy will be performed for the treatment of patients assigned to this group.The key of this approach is that D2 lymphadenectomy is carried out according to the guidelines of National Comprehensive Cancer Network(NCCN) without dissociation of anterior lobe of transverse mesocolon and capsula pancreatis.

Treatment:

Procedure: Laparoscopic D2 lymphadenectomy
