Objective To evaluate the role of preoperative 64 multi-detector spiral CT (MDCT) in predicting the extent of radical resection for advanced gastric cancer (AGC)． MethodsThe imaging data of 70 patients with AGC were collected and analyzed. The N2 lymph node metastasis was predicted by the MDCT indications, and compared with that postoperative pathological results. Results Sixty-two patients were treated with surgical intervention. The sensitivity, specificity, and accuracy of N2 positive prediction by MDCT was 92.0% (46/50), 75.0% (9/12) and 88.7% (55/62), respectively. Extended resection was performed in 81.6% (40/49) patients who were predicted as N2 positive, and D2 resection was performed in 92.3% (12/13) patients who were predicted as N2 negative.Conclusion The MDCT is a valuable technique to predict N2 lymph node metastasis, and to determine the extent of resection for AGC.
ObjectiveTo analyze the related risk factors of influencing on postoperative severe complications (PSC) in elderly patients with gastric cancer. MethodsAltogether 202 cases of elderly patients with gastric cancer who received surgical treatment between January 2003 and December 2008 in this hospital were analyzed. On the basis of the degree of complications, the patients were divided into the group with PSC and the group without PSC. The relevant clinical and laboratory data were evaluated, and compared with statistical analysis. ResultsClinically the preoperative comorbidity, total gastrectomy, more than 800 ml intraoperative blood loss, intraoperative transfusion, and combined organ resection were significantly correlated with PSC (Plt;0.05). In laboratory data, the lower preoperative serum albumin and the blood glucose level on the first day after operation were significantly correlated with PSC (Plt;0.05). ConclusionThe preoperative comorbidity, lower serum albumin, and extended radical resection are the danger factors leading to PSC.
Objective To investigate the reasonable indication of splenectomy in radical resection for advanced proximal gastric cancer (APGC). Methods Fifty patients with APGC were studied and classified into total gastrectomy with splenectomy (TGS) group (n=18) and total gastrectomy without splenectomy (TG) group (n=32). The operation time, hospitalized duration, complications, and lymphe node metastasis at the spleen hilus were compared between two groups. Results The operation time, hospitalized duration and subphrenic infection rate in the TGS group were significantly higher than those in the TG group (Plt;0.05). The rate of lymph node metasitasis of No.10 and No.11 in the TG group was not different from that in TGS group (Pgt;0.05). Conclusion Direct spleen and its vessel invasion are the reasonable indication of splenectomy in radical resection for APGC.
Objective To evaluate the clinical application of modified Orr Roux-en-Y type digestive tract reconstruction. Methods Thirty-eight patients with gastric cancer were randomly classified into modified group （accepted modified Orr Roux-en-Y type digestive tract reconstruction, 18 cases） and ρ group （accepted ρ type esophagojejunostomy, 20 cases） according to the date of operation. Operative time, blood loss in operation, complications after operation, emptying time of pouch, and change of body weight before and 3 months after operation were compared between two groups. Results Compared with the ρ group 〔(283±35) min〕, the operative time of modified group 〔(229±18) min〕 was significantly shorter （Plt;0.05）. The holo-empyting time of pouch in modified group 〔(35.7±4.9) min〕 was longer than that in ρ group 〔(3.0±0.5) min〕, Plt;0.01. Blood loss in operation, complications after operation, and the body weight change had no statistical difference between two groups （Pgt;0.05）. Conclusion Modified Orr Roux-en-Y type reconstruction with a pouch function is useful in clinical application， which is not only easy to operate, but also can reduce the operative time and the complications.
