ABSTRACT
Objective To investigate the diagnosis and treatment of gastric stromal tumor(GST). Methods Retrospective analysis was made on the clinical data of 18 cases of GST. The diagnosis of 18 cases was confirmed by pathology. Local resection of the tumor was performed in 2 cases,partial gastrectomy in 5 cases, subtotal gastrectomy in 9 cases, and total gastrectomy with lymph node clearance in 2 cases. Results Most of the patients were over forty years old.In 55.5% of cases,the location of tumor was at the middle of the stomach,and 61.0% of cases were intragastric growth type.The preoperative diagnostic rate was 27.8%,misdiagnostic rate was 72.2%.The resectability rate was 100%. No postoperative complications and operative death occurred in this series. Fifteen cases were followed up for 1 to 10 years. During follow up,2 cases died of recurrence of the tumor, and the other patients were still alive. Conclusion The GST patients lack typical clinical manifestations, and the preoperative diagnosis is difficult.Barium meal examination and gastroscopy are the main supplementary examinations.A combination of histological and immunohistochemical examinations is helpful to confirm the diagnosis.Surgical resection is the only effective therapeutic method.
ABSTRACT
Objective To compare of the effect of portaazygous devascularization(PADV) and combination operation(splenorenal shunt plus portaazygous devascularization)on the treatment of esophageal variceal bleeding(EVB).Methods 28 cases of EVB admitted from October 1995 to October 2000 were divided randomly into two groups:(1)PADV group (14 cases);(2) combination operation(14 patients).The free portal pressure(FPP) and portal veinous flow(PVF)were measured intraoperatively; and pre and post-operative barium meal and therapeutic effect between 2 groups were compared.Results The average value of FPP of PADV group and combination operation group reduced (4.81?7.26)cmH 2O and (10.03?2.66)cmH 2O respectively after operation, there were significant difference (both P
