ABSTRACT
Digestive tract reconstruction is an important part of gastric carcinoma operation as well as tumor resection and lymph node dissection.Surgeons are seeking the optimal reconstruction method that reduces the occurrence of complications and maintains better quality of postoperative life extremely.Uncut Roux-en-Y anastomosis is a modified procedure in which an artificial jejunal occlusion is devised to avoid Roux stasis syndrome based on Billroth Ⅱ and Braun's anastomosis.Compared to the conventional Roux-en-Y anastomosis,the uncut Roux-en-Y anastomosis retains the advantage of preventing biliary and pancreatic secretions reflux,furthermore,it can decrease the symptoms associated with Roux stasis owing to the abnormal myoelectrical conduction of Roux limb.Because the early studies indicated that there was higher incidence of dehiscence or recanalization of the jejunal occlusion,the uncut Roux-en-Y anastomosis has not been widely applied.Since jejunal occlusion has been optimized recently,the uncut Roux-en-Y reconstruction may be an optional and appropriate method of digestive tract reconstruction after distal gastrectomy.
ABSTRACT
Colorectal cancer is one of the most common malignant tumor with high mortality rate.About a third of patients with colorectal cancer have either simultaneously or metachronous liver metastasis with poor prognosis.Therefore,the studies on the mechanisms of colorectal liver metastasis is significant.Recently,the research on the molecular mechanisms of colorectal liver metastasis is increasing,this paper summarizes some of them,and we hope providing new ideas for the diagnosis and treatment of colorectal cancer patients with liver metastasis.
