Methods Sixty-six postoperative patients with gastric cancer combined diabetes were divided into 3 groups according to the balanced principle. In the frist group (FD group), FD was the nutrition preparation for 21 patients. In the second group (fresubin group), fresubin and the ordinary insulin injection were the nutrition preparation for 21 patients. In the third group (TPN group), the nutrition preparation came from TPN and the ordinary insulin injection for 24 patients. FD, fresubin or TPN were given at 24 h after operation, the levels of blood glucose for empty stomach, after meal (enteral nutrition or TPN) and the common complications compared among 3 groups of postoperative patients. Results ① In FD group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition were stable with little fluctuation and no insulin was needed with 1 case of hyperglycemia (4.8%). In fresubin group and TPN group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition or TPN were unstable with big fluctuation, with 6 cases (28.6%) and 8 cases (33.3%) of hyperglycemia, 5 cases (23.8%) and 6 cases (25.0%) of hypoglycemia in fresubin group and TPN group, respectively. Compared with fresubin group and TPN group, the rate of pathoglycemia was lower in FD group, the difference had statistical significance separately (Plt;0.05); There was no significant difference between fresubin group and TPN group (Pgt;0.05). ② The rates of infection of incisional wound in FD group (4.8%) and fresubin group (23.8%) were lower than that of TPN group (33.3%), there was significant difference among 3 groups (Plt;0.05); The time of passage of gas by anus in FD group and fresubin group were shorter than that in TPN group (Plt;0.05); There was no significant difference between FD group and fresubin group (Pgt;0.05). There were no significant differences of the rates of abdominal distension or diarrhea among 3 groups (Pgt;0.05). Conclusion Regarding postoperative patients with gastric cancer combined diabetes, in the early time field test group of the nutrition preparation, FD is better than fresubin or TPN, which does not increase the risk of the blood glucose change and have few complications.
ObjectiveTo explore the clinical effect of keeping the pancreatic capsule in radical gastrectomy for early stage of gastric cancer.
MethodsTwo hundreds and seven patients with early stage of gastric cancer who were treated in our hospital from Jan 2011 to December 2011 were enrolled prospectively, and were divided into experimental group (n=95) and control group (n=112). Patients in experimental group kept the pancreatic capsule in radical gastrec-tomy, but patients in control group didn't keep the pancreatic capsule. Comparison of the clinical effect between the 2 groups was performed.
ResultsThe blood loss[(134.1±5.3) mL vs. (150.3±3.7) mL] and operation time[(76.4±5.7) min vs. (87.5±9.1) min]of experimental group were all lower or shorter than those of control group (P<0.05), but there were no significant difference between the 2 groups in incidence of total complication[7.37% (7/95) vs. 10.71% (12/112)], stomal leak[3.16% (3/95) vs. 4.46% (5/112)], and anastomotic stenosis[4.21% (4/95) vs. 6.25% (7/112)], P>0.05. All of the 207 patients were followed-up for 1-36 months, with the median time of 17.5 months. During the follow-up period, in experimental group, there were 30 patients suffered from recurrence, 23 patients suffered from metastasis, and 44 patients died, and the 1-and 3-year survival rates was 84.21% (80/95) and 53.68% (51/95) respectively, 1- and 3-year disease free survival rates was 80.00% (76/95) and 48.42% (46/95) respectively; in control group, there were 37 patients suffered from recurrence, 23 patients suffered from metastasis, and 49 patients died, and the 1-and 3-year survival rates was 85.71% (96/112) and 56.25% (63/112) respectively, 1-and 3-year disease free survival rates was 81.25% (91/112) and 49.11% (55/112) respectively. There were no significant difference in the 1-and 3-year survival rate, 1-and 3-year disease free survival rate (P>0.05). In addition, there were no significant difference in the survival and disease free survival situation (P>0.05).
ConclusionsSurvival and disease free survival situation of keeping the pancreatic capsule in radical gastrectomy is similar with traditionally radical gastrectomy, but surgery of keeping the pancreatic capsule in radical gastrectomy has the advantages of less bleeding and shorter operation time, which is worthy of further study.
Objective
To systematically review the efficacy and safety of totally laparoscopic total gastrectomy (TLTG) versus laparoscopic-assisted total gastrectomy (LATG) for patients with gastric cancer.
Methods
Databases including PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI were searched to collect cohort studies about TLTG vs. LATG for gastric cancer from inception to February 28th 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.
Results
A total of six cohort studies were included, of which 407 cases were in the TLTG group, and 315 cases were in the LATG group. The results of meta-analysis showed that compared with LATG group, patients in TLTG group had shorter operation time (MD=–8.97, 95%CI –16.21 to –1.73, P=0.02), and initial postoperative feeding time (MD=–0.30, 95%CI –0.57 to –0.03, P=0.03). However, the anastomic time, bleeding volume, the number of dissected lymph nodes, proximal resection margin, initial flatus time, postoperative hospital stay, overall postoperative complications, anastomotic fistula, and anastomotic stenosis were similar between two groups (all P values>0.05)．
Conclusions
Compared with LATG, TLTG has shorter operation and recovery time for patients with gastric cancer. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To summarize the research progress of digestive tract reconstruction after total gastrectomy in gastric cancer. Methods The domestic and international published literatures about digestive tract reconstruction after total gastrectomy in gastric cancer were retrieved and reviewed. Results More and more attention had been paid to the postoperative quality of life after total gastrectomy in gastric cancer， and the most related factor for postoperative quality of life was the type of digestive tract reconstruction. The pouch reconstruction and preservation of enteric myoneural continuity showed beneficial effects on clinical outcomes. Current opinion considered the pouch reconstruction might be safe and effective， and was able to improve the postoperative quality of life of patients with gastric cancer. However， the preservation of duodenal pathway didn’t show significant benefits. Conclusion The optimal digestive tract reconstruction after total gastrectomy is still debating， in order to resolve the controversies， needs more in-depth fundamental researches and more high-quality randomized controlled trials.
ObjectiveTo explore risk factors of gastric paralysis following gastrectomy of gastric cancer and analyze its causes.
MethodsThe clinical data of 116 patients with gastric cancer for hospitalization time more than 21 days following gastrectomy were retrospectively analyzed from October 2011 to October 2013 in this hospital, in which 16 patients with gastric paralysis and 116 patients without gastric paralysis. The factors relevant gastric paralysis were analyzed by logistic regression analysis.
ResultsThe results of single factor analysis showed that the preoperative body mass index, history of diabetes, operative time, postoperative cardiovascular complications, albumin and hemoglobin levels within 3 d after operation, time to get out of bed after surgery, extubation time of gastric tube, the first drinking time and the first feeding time were associated with the gastric paralysis (P < 0.05), but the gender, age, time of diabetes history, life mode, smoking history, hypertension history, pylorus preserving or not, laparoscopy or not, intraoperative blood loss, intraoperative blood transfusion, uses of postoperative intraperitoneal chemotherapy drugs and postoperative analgesic drugs, and indwelling time of jejunum nutrition tube were not associated with gastric paralysis (P > 0.05). The results of logistic regression analysis showed that the preoperative body mass index, history of diabetes, operative time, time to get out of bed after surgery, and postoperative cardiovascular complications were the independent risk factors of gastric paralysis (P < 0.05).
ConclusionsThere are many factors that affect occurrence of gastric paralysis following gastrectomy of gastric cancer. Preoperative or intraoperative positive prevention measures could be taken according to the factors that might affect occurrence of gastric paralysis, which might be reduce gastric paralysis following gastrectomy of gastric cancer.
Objective To study the expressions of Wnt5a, MMP2, and MMP14 in the primary lesions of gastric cancer and the influences on clinicopathologic features. Methods The expressions of Wnt5a, MMP2, and MMP14 in the specimens of 106 patients with gastric cancer and 39 patients from the adjacent normal gastric tissues were detected by immunohistochemical staining, χ2 test and non-parametric test were used to analyze the relationships among them and between them and their influences on the clinicopathologic features. Results Extensive expressions of Wnt5a, MMP2, and MMP14 were demonstrated in the gastric cancer, which were significantly higher than those in the normal gastric tissues respectively (Plt;0.05). Positive expression of Wnt5a was associated with larger tumor diameter, deeper depth of invasion, higher degree of regional lymph node metastasis, later TNM stage, and higher rate of lymph node metastasis (Plt;0.05). In addition, Wnt5a expression was also associated with lymphatic infiltration and vascular infiltration (Plt;0.05). The expressions of MMP2 and MMP14 were associated with lymphatic infiltration, but not with vascular infiltration. Higher expressions of MMP2 and MMP14 were correlated with deeper tumor invasion, higher degree of regional lymph node metastasis, later TNM stage, and higher rate of lymph node metastasis (Plt;0.05). In addition, higher expression of MMP2 possesed greater tumor diameter (Plt;0.05). Spearman rank correlation analysis revealed the positive relation between Wnt5a and MMP2 （rs=0.240, P=0.014）, Wnt5a and MMP14 （rs=0.251, P=0.010）, as well as MMP2 and MMP14 （rs=0.444, P=0.000）. Conclusion Higher expressions of Wnt5a, MMP2, and MMP14 seem to promote invasion and metastasis of gastric cancer, and there are positive relations among their expressions.
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 evaluate the effectiveness and safety of implanted sustained-release fluorouracil in gastric cancer surgery. Methods Literature search was conducted in the following databases: PubMed, EMbase, The Cochrane Library (Issue 6, 2012), CNKI, VIP and WanFang Data from inception to June, 2012. Randomized controlled trials (RCTs) or quasi-randomized controlled trials on implanted sustained-release fluorouracil for gastric cancer were included. Two reviewers independently identified the literature according to the inclusion and exclusion criteria, and then extracted the data and assessed the quality of the included studies. Then, meta-analysis was conducted using RevMan 5.1 software. Results A total of 7 studies involving 742 patients were included. The results of meta-analysis showed no significant difference in the rate of postoperative complications between the two groups (OR=0.93, 95%CI 0.54 to 1.59, P=0.79), while a significant reduction was found in the recurrence rate in the sustained-release fluorouracil group during 1 to 3 year follow-up (1 year after surgery: OR=0.32, 95%CI 0.22 to 0.46, P=0.02; 2 years after surgery: OR=0.19, 95%CI 0.08 to 0.42, Plt;0.001; 3 years after surgery: OR=0.40, 95%CI 0.24 to 0.67, P=0.004). As for the survival rate, no significant difference was found between the two groups 1 year after surgery (OR=1.98, 95%CI 0.92 to 4.25, P=0.08), while it was significantly higher in the sustained-release fluorouracil group than in the control group 2 to 3 years after surgery (2 years after surgery: OR=2.63, 95%CI 1.17 to 5.91, P=0.02; 3 years after surgery: OR=2.42, 95%CI 1.53 to 3.83, P=0.002). Adverse reaction rates in the sustained-release fluorouracil group were lower than those in the control group, but without significantly differences between the two groups (OR=1.22, 95%CI 0.49 to 3.07, P=0.67). Conclusion Compared with the control group, implanted sustained-release fluorouracil for gastric cancer can significantly reduce the recurrence rate 1 to 2 years after surgery and improve the overall survival rate 2 to 3 years after surgery without increasing the incidences of the postoperative complications and adverse reaction. However, due to the limitation of quantity and quality of the included studies, this conclusion should be further confirmed by more high quality, larger sample and multi-center RCTs.
ObjectiveTo detect the expression of motilin in gastric cancer tissues and to explore the relationship between motilin protein expression and clinicopathologic characteristics of gastric cancer. MethodsThe immunohistochemical staining was used to detect the expression of motilin protein in gastric cancer, paracancerous tissues, and normal gastric mucosa tissues. The relationship between motilin protein expression and clinicopathologic characteristics of gastric cancer was analyzed. ResultsThe expression of motilin protein in gastric cancer tissues (1 206.43±631.67) was significantly higher than that in normal gastric mucosa tissues and paracancerous tissues, respectively (Plt;0.01). The difference of motilin protein expression between normal gastric mucosa tissues and paracancerous tissues was not significant (Pgt;0.05). The expression of motilin protein in gastric cancer was correlated with the site of tumor, differentiation degree, and lymph node metastasis (Plt;0.05). ConclusionMotilin may participate in the carcinogenesis of gastric cancer, and correlated with the invasion and metastasis of gastric cancer.
Objective To evaluate the rational of peritoneal warm perfusion chemotherapy after the operation. MethodsOne hundred and two patients with gastric cancer were included in this study. One hundred milliliter of peritoneal fluid were collected respectively after opening the abdomen,before closing the peritoneal cavity,and after hyperthermic peritoneal perfusion chemotherapy for free cancer cells examination. ResultsAfter opening the abdomen, the positive rate of free cancer cells was 36.3%(37/102), and the positive rate before closure of peritoneal cavity was 52.9%(54/102), 31 cases of free cancer cells were found killed after the warm perfusion chemotherapy,the effect rate was 57.4%(31/54).The free cancer cells positive rate related to the tumor infiltration depth, serous membrane invasion area and the type of histopathology. Conclusion In the peritoneal cavity of patients with gastric cancer, free cancer cells are able to survive and have a high degree of activity. Hyperthermic peritoneal perfusion chemotherapy is an effective method to kill free cancer cells.
