ABSTRACT
Objective To investigate the therapeutic effects of endoscopy for palliative treatment of advanced pancreatic cancer. Methods A typical case of un-resectable advanced pancreatic cancer was reviewed, who underwent obstruction of upper gastrointestinal tract, obstructive jaundice and alimentary tract hemorrhage subsequently. The patient received multiple placement of intestinal tract stents, common bile duct stents and hemostatic treatment endoscopically. Because of the obstruction of upper gastrointestinal tract, jejunalostomy and retrograde endoscopy through the orificium fistulae were performed to place bile duct stents. Results The patient survived for 10 months with good life quality after diagnosis, obstruction of upper gastrointestinal tract, obstructive jaundice and alimentary tract hemorrhage were cured and didn't recur till death.Conclusion Therapeutic endoscopy, safe and effective, is the first choice for advanced pancreatic cancer complicated with obstruction of digestive tract (including gastrointestinal tract, bile duct and pancreatic duct).
ABSTRACT
[Objective] To explore the techniques of hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure. [Methods] 18 patients with portal hypertension were operated by hand-assisted laparoscopic splenectomy plus portozygos disconnection. [Results] The operations were completed successfully. The mean operative time was 180(150～260) minutes, the mean blood loss estimated was 540(200～2 000) mL, the mean weight of spleen was 910 (500～2000) g and the mean length of hospital stay was 9.7 (8～18) days after operation. All patients had recovered rapidly and suffered less pain and only 5 patients needed analgesic. The mean recovery time of the bowel function was 52(24～74) hours. The hand incisions healed well, and only one occurred complications and another suffered death. [ Conclusions ] Hand-assisted laparoscopic splenectomy plus portozygos disconnection procedure is to be feasible and safe, and has the merits of minimally invasive surgery.
ABSTRACT
Objective To study the feasibility and curative effect of laparoscopic radical resection of rectal carcinoma. Methods Sixty-two cases were enrolled in this study between Feb 2003 and Mar 2005, including 32 cases undergoing laparoscopic radical resection (19 Dixon and 13 Miles) , and 30 cases undergoing open radical resection (22 Dixons and 8 Miles). Results The mean operation time of laparoscopic group was 195 min, and open group was 156 min (P 0. 05 ). The GI and urination function of laparoscopic group recovered faster than open group ( evacuated was 2. 7 days vs. 3. 7 days, P
ABSTRACT
Objectives:To investigate the influence of PN via portal vein on insulin and glucagon in liver regeneration. Methods:The rabbits were randomly devided into control group( n =5),PN via portal vein group(group Ⅰ, n =10) and PN via central vein group(group Ⅱ, n =10).The PN was performed for 6 days after partial hepatectomy.The concentration of serum insulin and glucagon in portal and perpheral vein were analysed with radioimmunoassay. Results:The concentration of serum insulin was increased in group Ⅰ and group Ⅱ,and it was increased significantly( P 0.05),but it was increased significantly in portal vein blood in group Ⅰ( P
