ABSTRACT
Objective To explore the safety and effectiveness of central venous catheter for thoracic drainage after esoph-agectomy.Methods We prospectively analyzed 95 patients who underwent esophagectomy for esophageal carcinoma in our de-partment from August 2016 to August 2017.Forty-six patients with central venous catheter drainage were observation group, and 49 patients with traditional chest-tube closed drainage were control group.Compared the differences of drainage amount, pain score, postoperative patient quality of life score, duration of drainage and chest tube incision healing between the two groups.Results There were no significant differences in daily drainage volume and patency of drainage tube between the two groups(P>0.05).Compared with the control group, the duration of thoracic drainage in the observation group was significant shorter, the pain intensity score was significant lower , and the emotional function of postoperative patient quality of life was sig-nificant better(P<0.01).There were more patients suffered uncomfortable symptoms, such as nausea, vomiting, pain, in-somnia in the control group(P<0.05).Conclusion The application of central venous catheter in thoracic drainage can de-crease the postoperative pain and improve the postoperative quality of life for esophageal carcinoma patients after esophagecto-my.It is safe and feasible for thoracic drainage after esophagectomy .
ABSTRACT
Objective To investigate the perioperative characteristics and changing trends of gastric electrical activity of thoracic (tube) stomach in patients with esophageal cancer.Methods The clinical data of 30 patients with esophageal cancer who were admitted to the Sichuan Cancer Hospital between March 2013 and November 2013 were prospectively analyzed.All the eligible patients underwent esophageal cancer resection by Ivor-Lewis according to the inclusion criteria.The electrogastrograms of patients were recorded at preoperative day 1 and at postoperative day 3,7, 11 and 30.The electrogastrograms of patients at preoperative day 1 were used as the control.The parameters of electrogastrogram were analyzed including main frequency, coefficient of dominant frequency instablility, main power, postprandial/preprandial power ratio, percentage of normal gastric slow wave,percentage of slow gastric slow wave and percentage of tachycardia gastric slow wave.Measurement data with normal distritution were presented as x ± s, and measurement data with skew distritution were presented as M (Qn).The postoperative time and pre-and post-prandial electrogastrograms were compared by the repeated measures two-way ANOVA.The comparison between groups were evaluated with the LSD test and analysis of variance.Results Thirty patients were screened for eligibility with a mean age of 62 years (range, 49-75 years), including 26 males and 4 females.The pre-and post-prandial main frequencies were changed from 2.83 ± 0.13 and 3.01 ± 0.17 before operation to 2.66 ± 0.10 and 2.82 ± 0.10 at postoperative day 30 with coherent changing trend.The main frequencies at postoperative each time points were significantly lower than those before operation while postprandial above indicators were higher than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =285.62, P ＜ 0.05).There was no interaction between the time and meal (F =0.22, P ＞ 0.05).The pre-and post-prandial coefficients of dominant frequency instablility were changed from 0.133 ±0.031 and 0.045 ±0.019 before operation to 0.150 ±0.043 and 0.115 ±0.010 at postoperative day 30 with coherent changing trend, and coefficients of dominant frequency instablility at postoperative each time points were significantly higher than those before operation while postprandial above indicators were lower than preprandial those, showing a significant reducing trend with the passage of postoperative time (F =16.51, P ＜ 0.05).The pre-and post-prandial main powers were changed from (85 ± 15) μV and (149 ± 23) μV before operation to (74 ± 9) μμV and (98 ± 10) μV at postoperative day 30, and main powers at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =48.45, P ＜ 0.05).There was interaction between the time and meal (F =7.39, P ＜ 0.05).The postprandial/preprandial power ratio was changed from 3.00 ± 0.35 before operation to 2.52 ± 0.25 at postoperative day 30, and postprandial/preprandial power ratios at postoperative each time points were significantly lower than those before operation, showing a significant increasing trend with the passage of postoperative time (F =26.66, P ＜ 0.05).The pre-and post-prandial percentages of normal gastric slow wave were changed from 81％ ± 6％ and 94％ ± 5％ before operation to 57％ ± 5％ and 70％ ± 5％ at postoperative day 30 with coherent changing trend, and percentages of normal gastric slow wave at postoperative each time points were significantly lower than those before operation while postprandial above indicators was lower than preprandial those, showing a significant increasing trend with the passage of postoperative time (F =49.36,P ＜0.05).There was no interaction between the time and meal (F =0.24, P ＞ 0.05).The pre-and postprandial percentages of slow gastric slow wave were changed from 17％ ± 7％ and 4％ ± 4％ before operation to 32％±4％ and 21％±4％ at postoperative day 30 with coherent changing trend, and percentages of slow gastric slow wave at postoperative each time points were significantly higher than those before operation while preprandial above indicators were higher than postprandial those, showing a significant reducing trend with the passage of postoperative time (F =46.54, P ＜ 0.05).There was interaction between the time and meal (F =18.12, P ＜ 0.05).The pre-and post-prandial tachycardia gastric slow wave percentages were changed from 1.55％ (1.04％,2.21％) and 1.95％ (1.74％, 4.22％) before operation to 8.97％ (5.76％, 12.02％) and 12.41％ (8.04％,16.85％) at postoperative day 30 without completely coherent changing trend, and percentages of tachycardia gastric slow wave at postoperative each time points were significantly higher than those before operation while postprandial above indicators were higher than preprandial those, showing a significant difference between before operation and postoperative day 3 (Z =11.47, 13.28, P ＜ 0.05) and no significant difference among the postoperative day 7, 11, 30 (Z =1.88, 0.31, 0.03, P ＞ 0.05).There was no interaction between the time and meal (F=0.85, P＜0.05).Conclusions After the esophagectomy, gastric electrical activity of thoracic (tube) stomach is also retained before and after the meal.There are significant differences among the main frequency, main power, coefficients of dominant frequency instablility, postprandial/preprandial power ratio,percentage of normal gastric slow wave, percentage of slow gastric slow wave, percentage of tachycardia gastric slow wave of thoracis (tube) stomach, they have changed dynamically in the perioperative period.
ABSTRACT
Esophageal cancer is one of the most common malignant tumors in China.At present, the best treatment of esophageal cancer is surgery.For the patients with cervical lymph nodes metastases, three-field lymph nodes dissection is the main solution.Ultrasonography and computed tomography (CT) of the neck play a decisive role in the preoperative examinations for patients with esophageal cancer, and should be used as routine examinations before surgery at the qualified hospital in order to improve the accuracy of preoperative assessment of cervical lymph nodes metastases of esophageal cancer and screen potential patients with esophageal cancer undergoing three-field lymph nodes dissection.
ABSTRACT
Objective To explore the relationship between the anastomotic plane and gastric esophageal reflux by analysizing three different anastomotic plan pressure and esophageal 24 h dynamic pH.Methods From June 2011 to March 2012, 45 patients with esophageal cancer had undergone radical surgery.According to the different locations of esophageal carcinoma, we divided patients into three groups(cervical esophagogastrostomy group, above aortic arches for esophagogastrostomy group, low aortic arches for esophagogastrostomy group).we monitored the LESP, esophageal wet swallowing peristalsis amplitude and 24 h dynamic pH value two days before surgery, and monitored the anastomotic plane pressure, residual esophageal wet swallowing peristalsis amplitude and 24 h dynamic pH value 1 month and 2 months after surgery in the same way.Results Three groups' difference of LESP, esophageal wet swallowing peristalsis amplitude and percentage of total time of 24 h dynamic pH ＜4in preoperative was not statistically significant.The difference of esophagogastrostomy plane pressure in postoperative was not statistically significant, but the wet swallowing peristalsis amplitude and percentage of total time of 24 h dynamic pH ＜ 4 in postoperative was statistically significant.Three groups' difference of LESP(compared with esophagogastrostomy plane pressure), wet swallowing peristalsis amplitude and percentage of total time of 24 h dynamic pH ＜ 4 between preoperative and postoperative was also statistically significant.Conclusion For patients with esophageal neoplasms, we should completely resection the tumor, and remain esophagus as much as possible.
ABSTRACT
Background and purpose: Postoperative chemotherapy targets the metastatic cancer in the remaining lymph nodes, but the heterogeneity in multidrug resistance (MDR) of metastatic cancer cells is a main factor affecting chemotherapeutic efficacy. Recent studies only examined the primary lesion of esophageal squamous cell carcinoma(ESCC). There is no report about heterogeneity between the primary tumor and metastases lymph node. The purpose of this study was to explore the heterogenous expression and clinical signiifcance of multidrug resistance (MDR) associated proteins in primary tumors and metastatic lymph nodes in patients with thoracic ESCC. Methods:The expressions of lung cancer associated resistance protein (LRP), P-glycoprotein (P-gp), topoisomeraseⅡ(TOPO-Ⅱ), thymidylate synthase (TS), glutathione S-transferase-π (GST-π) were examined by immunohistochemistry in primary lesions and corresponding metastatic lymph nodes in 54 patients with thoracic ESCC. The differences between expression of primary lesions and matched metastatic lymph nodes were compared and analyzed in relationship with tissue differentiation degree. Results: The discordant rates of the expression and drug resistance between primary lesions and corresponding metastatic lymph nodes in LRP, P-gp, TS, TOPO-Ⅱ and GST-π were 63.0% and 26.9%, 42.6%and 22.2%, 48.1%and 25.9%, 50.0%and 29.6%, 18.5%and 1.9%respectively. The expression of LRP showed signiifcant difference between the primary tumors and lymph nodes (P=0.026). No signiifcant differences were found for the other four proteins, and GST-πwas expressed in all patients in both the primary tumors and lymph nodes. Protein expression was not associated with degree of differentiation. Conclusion:There is evident of heterogenous expression of MDR associated proteins in metastatic lymph nodes compared to the primary tumors of ESCC. The examination of expression levels of MDR associated proteins in metastatic lymph nodes is helpful to select the postoperative rational chemotherapy plan.
ABSTRACT
Objective To evaluate the efficacy of circinal stapled suture and manual suture in cervical esophagogastric anastomosis in esophageal resection.Methods The clinical data of 187 patients with esophageal cancer who were admitted to the Cancer Hospital of Sichuan Province from January 2010 to January 2012 were retrospectively analyzed.All the patients were divided into the stapled suture group (98 patients) and manual suture group (89 patients).The time of anastomosis,operation time,time for dieting,duration of hospital stay,the incidence of postoperative complications and positive rate of esophageal remnant cancer cells of the 2 groups were compared.All data were analyzed using the t test or chi-square test.Results The time of anastomosis,operation time,time for dieting and duration of hospital stay were (7.8 ± 1.4) minutes,(227 ± 60) minutes,(6.3 ± 0.9) days and (14 ±4)days in the stapled suture group,which were significantly shorter than (28.5 ±2.3)minutes,(301 ±81)minutes,(8.4 ± 1.0)days and (22 ±9) days in the manual suture group (t =75.44,7.14,7.71,7.41,P ＜0.05).The incidence of anastomotic fistula was 1％ (1/98) in the stapled suture group,which was significantly lower than 8％ (7/89) of the manual suture group (P ＜ 0.05).The incidence of anastomotic stricture was 5％(5/98) in the stapled suture group,which was lower than 7％ (6/89) in the manual suture group,but no significant difference was detected (P ＞0.05).The positive rate of esophageal remnant cancer cells was 0(0/98),which was signifiantly lower than 4％ (4/89) in the manual suture group (P ＜0.05).Conclusion Circinal stapled suture in esophagogastric cervical anastomosis not only reduce the time of anastomosis,operation time and duration of hospital stay,but also decrease the incidence of anastomotic fistula and the positive rate of esophageal remnant cancer cells.
ABSTRACT
ObjectiveTo explore the effect of different nutritional support mdoes on humoral immunity and outcomes after esophagectomy in patients with esophageal carcinoma.MethodsForty-six patients with middle or low thoracic esophageal carcinoma underwent Ivor Lewis esophagectomy.The patients were randomized into enteral nutrition group ( EN,n =23 ) and enteral combined parenteral nutrition group ( EN + PN,n =23 ) based on the nutrition support modes.Serum levels of immunoglobulin (IgG,IgA,IgM,IgE,κ/λ light chain) and comphments (C3/C4) were assayed and compared on the 1st pre-operative day and at 18 hours as well as 3rd and 7th day after operation.The clinical outcomes including infection-related complications and hospital stay were compared between two group s.ResultsThere was no significant difference in all humoral immunity indicators between two groups at the eachpost-operative time point.In both two groups,the levels ofIgG [ (8.90 ± 1.75),(7.53 ±1.41) g/Land (8.64±2.44),(7.48±2.16) g/L],κ [ (2.14±0.46),(1.78±0.41) g/L,and (2.15 ±0.63),( 1.86 ± 0.62) g/L] and λ light chain [ ( 1.34 ± 0.45 ),( 1.11 ± 0.31 ) g/L and ( 1.20 ± 0.32),( 1.08 ± 0.35 ) g/L] were significantly lower 18 hours and 3rd day after operation than the pre-operative levels [ (12.15±2.86)and (11.11±2.96) g/L,(2.90±0.77) and (2.77±0.79) g/L,(1.79±0.57) and (1.56±0.41) g/L] (P=0.000,P=0.000,and P=0.004,P=0.000,and P=0.000,P=0.000,and P=0.011,P=0.000,and P=0.004,P=0.000,and P =0.008,P =0.000),and returned to the preoperative levels by the postoperative 7th day (P＞0.05),except for the level of κ light chain 7th day after operation in EN group [ ( 2.42 ± 0.69) g/L] ( P =0.027 ).The levels of IgA,IgE,and C3 were not significantly different during the perioperative period ( P ＞ 0.05 ).The level of IgM was not significantly different during the perioperative period in EN group (P ＞0.05),and was significantly lower on the 3rd post-operative day [ ( 1.00 ±0.53) g/L] than the pre-operative level [ ( 1.47 ±0.76) g/L] in the EN + PN group (P =0.031 ),and were not significantly different on the other time points (P ＞ 0.05 ).In the EN group,the C4 level was significantly lower at the postoperative 18 hours [ (0.24 ±0.08) g/L] than the pre-operative level [ (0.37 ±0.36) g/L] (P =0.030),and were not significantly different at the other time points ( P ＞ 0.05 ).In the EN + PN group,the C4 level was not significantly different during the perioperative period ( P ＞ 0.05 ).There was no significant difference in the infection-related complications and hospital stay between these two groups ( P =0.300,P =0.371 ).ConclusionsThe effects of EN or EN + PN on humoral immunity and outcomes after esophagectomy in patients with esophageal carcinoma are not different.Both these two nutritional support modes can not completely alleviate the harm to the humoral immunity.The EN is more cost-effective.
ABSTRACT
