ABSTRACT
Objective To discuss the manifestations, diagnosis and management of acute superior mesenteric artery occlusion (ASMAO). Methods The clinical data of 15 cases of ASMAO admitted in our hospital between 2000 and 2007 were analyzed retrospectively. Results The causes of ASMAO were mesenteric artery embolism in 11 patients and mesenteric artery thrombosis in 4 patients. All cases underwent emergency laparotomy, in which 2 cases underwent removal of the embolus, 11 cases were subjected to resection of necrotic bowel after removal of the embolus, and 2 cases gave up definite surgery. Postoperative heparin anticoagutherapy was used in all patients. The overall mortality rate was 27% (4 cases). Conclusions Acute superior mesenterie artery occlusion should be suspected in a patient with sudden abdominal pain, especially in those who have organic cardiac disease. Early diagnosis and prompt embolectomy are the key to save the patients.
ABSTRACT
Objective To approach the effect of prosthetic valve at preventing reflux esophagitis.Methods After the total gastrectomy and esophagojejunostomy,interrupted suture was apphed to form a prosthetic valve at output and input beyond Braun's stoma.Results Only one got light reflux esophagitis in 15 patients.Conclusion Prosthetic valve can prevent reflux esophagitis,and the operation is convenient and safe,which is deserved to be in generalization and approach the latest method.
ABSTRACT
Objective To evaluate the clinical significance of the intraoperative detection of peritoneal micrometastases of gastric cancer.Methods In selected 50 cases of gastric cancer in which no obvious peritoneal metastasis was found preoperatively or during laparotomy,Douglas′s pouch peritoneal biopsy was undertaken intraoperatively,then HE and CK-20 immunohistochemistry staining of the specimens was performed.The expression of CK-20 mRNA in peritoneal irrigation fluid was also determined by RT-PCR.Results HE staining of all cases was negative.The positive rate of CK-20 immunohistochemistry staining was 24.0 %(12/50),and 36.0 %(18/50) with RT-PCR method.The positive rate of CK-20 mRNA was significantly related with the histological type,the depth of invasion and the number of lymph node metastasis(P
ABSTRACT
Objective: To observe the role of parenteral nutrition and laparoscopic therapy in chylous ascites.Methods: A patient with chylous ascites was therapied with parenteral nutrition(4 weeks) and laparoscopic therapy and parenteral nutrition(1 week) subsequently.Output of ascites was daily measured from the drainage catheter of abdominal cavity.The body weight and other nutritional indexes were determined.Results: During the course of parenteral nutrition,the production and output of ascites gradually decreased,the body weight increased,and the serum album in level kept unchanged.After laparoscopic therapy and parenteral nutrition(1 week),ascites decreased significantly and did not rebound after diet,the body weight and the serum album in level also obviously increased.Conclusion: Laparoscopic therapy and parenteral nutrition are very useful in the treatment of patients with chylous ascites.
