Influence of liver function after laparoscopy-assisted totally laparoscopic gastrectomy.

Background: Previously, some studies have proposed that total laparoscopic gastrectomy (TLG) is superior to laparoscopic-assisted gastrectomy (LAG) in terms of safety and feasibility based on the related intraoperative operative parameters and incidence of postoperative complications. However, there are still few studies on the changes in postoperative liver function in patients undergoing LG. The present study compared the postoperative liver function of patients with TLG and LAG, aiming to explore whether there is a difference in the influence of TLG and LAG on the liver function of patients.

[Transumbilical single-port access laparoscopic surgery for colorectal cancer].

Objective: To evaluate the surgical outcomes after transumbilical single-port access laparoscopic surgery for colorectal cancer.

Methods: Patients undergoing transumbilical single-port access laparoscopic radical resection for colorectal cancer at the Zhongshan Hospital of Xiamen University were included.

Results: Three patients underwent transumbilical single-port access laparoscopic radical resection for sigmoid colon cancer and 1 for rectal cancer between August 2010 and September 2010.

[Expression of inductive nitric oxide synthase and vascular endothelial growth factor in colonic carcinoma, and their effects on tumor angiogenesis].

Objective: To investigate the expression of inductive nitric oxide synthase (iNOS) and vascular endothelial growth factor (VEGF), and their relations with clinicopathological parameters in colonic carcinoma.

Method: Immunohistochemistry (streptomycin avidin-biotin peroxidase complex, SP) was used to detect the expression of iNOS, VEGF, collagen IV, FVIII Ag in colonic adenocarcinoma, and micro vessel density (MVD) was counted.

Results: The positive rates of iNOS and VEGF in colonic carcinoma were 76% and 80% respectively.
