ABSTRACT

Objective To investigate the clinical results of end-to-end invagination pancreaticojejunostomy.end-to-end invagination pancreaticojejunostomy and duct-to-mucosa pancreaticojejunostomy of pancreaticoduodencetomy of patients with pancreatic and periampullary carcinoma. Methods Fifty-two patients underwent different pancreaticoduodenectomy in our hospital from August 1995 to July 2006 were collected and analyzed retrospectively.The incidence of pancreatic leakage,operation time,the blood loss and the postoperative complications were analyzed. Results Twenty-five patients received end-to-end invagination pancreaticojejunostomy.Sixteen patients received end-toside invagination pancreaticojejunostomy.Eleven patients received end-to-side pancreaticojejunal mucosa-mucosa anastomosis.The operation time of the duct-to-mucosa pancreaticojejunostomy was shorter than the two of the others(4 ~7.15 h).The perioperative comphcations occurred in 18 cases and the long-term postoperative complications occurred in 10 cases.The average length of stay in hospital was(19.32 ±5.45)days.Two cases died during perioperative period. Conclusion End-to-eed invagination pancreaticojejunostomy,end-to-side invagination pancreaticojejunostomy and end-to-side pancreaticojejunal mucosa-mucosa anastomosis are all common anastomosis methods.Pancreatic leakage is a serious postoperative complication.The selection of anastomosis method is based on the condition during operation.

ABSTRACT

Objective To compare the distribution of collagen type Ⅲ and Ⅳ in mucosa of normal and carcinoma cardiac tissues and to analyze the influence of changed collagen on auto-fluorescence after canceration.Methods Using immunohistochemical technique with monoclonal anti-collagen typeⅢ and Ⅳ,the difference of distribution in extracellular matrix of two types collagen between normal and carcinoma tissues from 16 patients were measured with semi-quantitative score methods.Results In normal mucosa,the epithelial basement membrane showed an intense positive reaction for monoclonal anti-collagen Ⅳ and an intensively stained ring band was formed around the grand basement membrane.The collagen type Ⅲ formed ring-like structures apparently representative of fibriform collagen immediately adjacent to the epithelial basement membrane.In carcinomatous mucosa,immunoreaction of the carinomatous cell nest was negative,and only remnants of positively were seen at the site of the former membrane by collagen type Ⅳ.The change of collagen type Ⅲ was not apparent and the positive reaction in carcinomatous stroma was more intensity than in normal stroma.There was significant difference in distribution of collagen type Ⅲ and Ⅳ between the normal and carcinomatous tissues(P
