ObjectiveTo investigate the postoperative risk factors for gastrointestinal stromal tumors.MethodsFrom December 2005 to December 2010,sixty-one gastrointestinal stromal tumors patients of People' s Hospital of Tongling city gastrointestinal surgery department were analyzed retrospectively.Using the logistic regression model to calculate the postoperative recurrence risk factors. Results Sixty-one patients underwent operation,including gastrectomy (40 cases ),partial intestina parva resection (7 cases),partial colon resection ( 3 cases ),Dixon' s operation ( 2 cases ) and tumorectomy ( 9 cases ).Fifteen patients were given postoperative imatinib Mesylate Capsules (Glivec) treatment.Fifty-seven patients were followed-up more than 1 year and 7 cases were found palindromia ( 12％ ).Logistic model shows that the malignant degree of gastrointestinal stromal tumors is the only risk factor of postoperative palindromia.ConclusionsMalignant degree of gastrointestinal stromal tumors is the main risk factor for postoperative palindromia.Imatinib mesylate capsules treatment may be beneficial to the greater stage patients.

Objective To investigate the impact of different hepatic vascular inflow occlusion methods on hepatic parenchymal function in partial hepatectomy.Methods Between 2009 and 2010,62 hepatocellular carcinoma (HCC) patients underwent partial hepatectomy.In 13 patients,partial hepatectomy was carried out without using any inflow occlusion (group A).In 29 patients intermittent Pringle's maneuver (group B) while in 20 patients selective hepatic inflow occlusion (group C) were used.Intraoperative indocyanine green retention rate at 15 minutes (ICGR15) was measured using pulse spectrophotometry before and during hepatectomy. Results (1) Blood loss in group A was greater than group B and C (P=0.016,P=0.001).(2) There was no significant difference in the preoperative ICGR15 values among group A,B and C.The intraoperative ICGR15 for group B was significantly higher than group A and C (P=0.011,P=0.030).(3) A significant correlation was found between the level of ICGR15 and total inflow clamp time (r =0.484,P =0.001) and blood loss (r=0.349,P=0.005),respectively.(4) Compared with group A and B,postoperative liver function recovered significantly faster in group C.Conclusion Selective hepatic inflow occlusion was useful in controlling blood loss and it was beneficial to the hepatic functional reserve in the liver remnant.
