Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided.RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients(RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery(P = 0.42) and stage of the disease(P = 0.16). Intraoperative blood loss was significantly lower in the LG(95.93 ± 119.22) and RG(117.91 ± 68.11) groups compared to the OG(127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG(27.78 ± 11.45), LG(24.58 ± 13.56) and OG(25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay(P < 0.0001). A similar complications rate was found(P = 0.13). The leakage rate was not different(P = 0.78) between groups.CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster postoperative functional recovery.展开更多

According to the tumor location, the patients were allocated to two different groups; two patients received robotic total gastrectomy with TVSE and the other six received robotic distal gastrectomy with TVSE.RESULTS: Surgical procedures were successfully performed in all eight cases without conversion. The mean age was 55.3(range, 42-69) years, and the mean body mass index was 23.2(range, 21.6-26.0) kg/m2. The mean total operative time and blood loss were 224(range, 200-298) min and 62.5(range, 50-150) m L, respectively. The mean postoperative hospital stay was 3.6(range, 3-5) d. The mean number of lymph nodes resected was 23.6(range, 17-27). None was readmitted within 30 d of postoperation. During the follow-up, no stricture developed nor was any anastomotic leakage detected.CONCLUSION: It is possible to perform a TVSE following a full robot-sewn gastrectomy with standard D2 lymph node resection for female gastric cancer patients.展开更多

Genomic DNA was prepared from peripheral blood leukocytes. Genotypes and allele frequencies were determined in patients and healthy controls using restriction fragment length polymorphism analysis of PCR products.RESULTS: The frequencies of IL-1β+3 594T, IL-10-1082G and CD14-159T allele were similar in patients with mild or severe pancreatitis and in controls. Within SAP patients, no significant differences were found in the allele distribution examined when etiology was studied again. Patients with septic shock showed a significantly higher prevalence of IL-10-1082G allele than those without shock (x2 = 5.921,P = 0.015).CONCLUSION: IL-10-1082G plays an important role in the susceptibility of SAP patients to septic shock. Genetic factors are not important in determination of disease severity or susceptibility to AP.展开更多

METHODS: Sixty-six patients undergoing gastrointe-stinal anastomosis proximal to the ileocecal junction were randomized into two groups according to the anastomotic method, CAC or stapler. RESULTS: The postoperative recovery of patients in CAC and stapled anastomosis groups was similar. No postoperative complication related to the anastomotic method was found in either group. Both upper gastrointestinal contrast radiography at the early postoperative course and endoscopic examination after a 6-mo follow-up showed a better healing at the compression anastomosis. CONCLUSION: CAC can be used not only in colonic surgery but also in gastrointestinal anastomosis. Our result strongly suggests that CAC anastomosis is safe in various complication circumstances. However, it should be further conf irmed with a larger patient sample.展开更多

Here, we aimed to evaluate whether patients who received neoadjuvant chemotherapy can be enrolled into the ERAS program for locally advanced gastric cancer. Methods: From April 2015 to July 2017, 114 patients who received neoadjuvant chemotherapy for locally advanced gastric cancer were randomized into ERAS and standard care (SC) groups. Postoperative length of stay, complications, bowel function, and nutritional status were recorded. Results: The postoperative length of stay of the ERAS group was shorter compared with that of the SC group (5.9 ± 5.6 vs. 8.1 ± 5.3 days, P=0.037).The postoperative complication rate was 9.3% in the ERAS group and 11.5% in the SC group(P=0.700).The time to first flatus (2.7 ± 2.0 vs. 4.5 ± 4.6 days, P = 0.010) and time to a semi-liquid diet (3.2 ± 2.1 vs. 6.3 ± 4.9 days, P 〈 0.001) in the ERAS group were shorter compared with those in the SC group. On the 10thday after surgery, the values of weight, total protein, albumin, and prealbumin of the ERAS group were lower compared with those of the SC group. Conclusions: Patients who received neoadjuvant chemotherapy could be enrolled into ERAS programs for locally advanced gastric cancer. The nutritional status of these patients was not adversely affected.展开更多

The Avrami equation was used to analyze the isothermal crystallization process, while the analysis of nonisothermal crystallization process was based on the Jeziorny-modified Avrami model and Mo model. The kinetics results of isothermal and nonisothermal crystallization verified the peculiar effects of branches on the crystallization process of PP backbones in PP-g-PS and PP-g-PnBA graft copolymers: on one hand, the interaction between branches (n-n interaction between PS branches, or dipole-dipole interaction between PnBA branches) restrained the mobility and reptation ability of the PP backbones, which hindered the crystallization process; on the other hand, the heterogeneous nucleation effect resulting from the branched structure and fluctuation-assisted nucleation mechanism (caused by microphase separation between the PS or PnBA rich phase and the PP rich phase) became more pronounced with increasing branch length, which facilitated the crystallization process.展开更多

The mean age was 55.3(range, 42-69) years, and the mean body mass index was 23.2(range, 21.6-26.0) kg/m2. The mean total operative time and blood loss were 224(range, 200-298) min and 62.5(range, 50-150) m L, respectively. The mean postoperative hospital stay was 3.6(range, 3-5) d. The mean number of lymph nodes resected was 23.6(range, 17-27). None was readmitted within 30 d of postoperation. During the follow-up, no stricture developed nor was any anastomotic leakage detected.CONCLUSION: It is possible to perform a TVSE following a full robot-sewn gastrectomy with standard D2 lymph node resection for female gastric cancer patients.

文摘AIM: To investigate IL-1β+3 594 in the 5th intron, IL-10-1 082 and CD14-159 polymorphisms in patients with acute pancreatitis (AP) and septic shock.METHODS: The study included 215 patients (109 with acute severe pancreatitis (SAP), 106 with acute mild pancreatitis (MAP)) and 116 healthy volunteers. Genomic DNA was prepared from peripheral blood leukocytes. Genotypes and allele frequencies were determined in patients and healthy controls using restriction fragment length polymorphism analysis of PCR products.RESULTS: The frequencies of IL-1β+3 594T, IL-10-1082G and CD14-159T allele were similar in patients with mild or severe pancreatitis and in controls. Within SAP patients, no significant differences were found in the allele distribution examined when etiology was studied again. Patients with septic shock showed a significantly higher prevalence of IL-10-1082G allele than those without shock (x2 = 5.921,P = 0.015).CONCLUSION: IL-10-1082G plays an important role in the susceptibility of SAP patients to septic shock. Genetic factors are not important in determination of disease severity or susceptibility to AP.
文摘AIM: To investigate the feasibility of compression anastomosis clip (CAC) for gastrointestinal anastomosis proximal to the ileocecal junction. METHODS: Sixty-six patients undergoing gastrointe-stinal anastomosis proximal to the ileocecal junction were randomized into two groups according to the anastomotic method, CAC or stapler. RESULTS: The postoperative recovery of patients in CAC and stapled anastomosis groups was similar. No postoperative complication related to the anastomotic method was found in either group. Both upper gastrointestinal contrast radiography at the early postoperative course and endoscopic examination after a 6-mo follow-up showed a better healing at the compression anastomosis. CONCLUSION: CAC can be used not only in colonic surgery but also in gastrointestinal anastomosis. Our result strongly suggests that CAC anastomosis is safe in various complication circumstances. However, it should be further conf irmed with a larger patient sample.
文摘Background:Enhanced recovery after surgery (ERAS) protocols or fast-track (FT) programs enable a shorter hospital stay and lower complication rate.Minimally invasive surgery (MIS) is associated with a lesser trauma and a quicker recovery in many elective abdominal surgeries.However,little is known of the safety and effectiveness made by ERAS protocols combined with MIS for gastric cancer.The purpose of this study was to evaluate the safety and effectiveness made by FT programs and MIS in combination or alone.Methods:We summarized an 11-year experience on gastric cancer patients undergoing elective laparotomy or minimally invasive gastric resection in standard cares (SC) or FT programs during January 2004 to December 2014.A total of 984 patients were enrolled and assigned into four groups:open gastrectomies (OG) with SC (OG + SC group,n =167);OG with FT programs (OG + FT group,n =277);laparoscopic gastrectomies (LG) with FT programs (LG + FT group,n =248);and robot-assisted gastrectomies (RG) with FT programs (RG + FT group,n =292).Patients&#39; data were collected to evaluate the clinical outcome.The primary end point was the length of postoperative hospital stay.Results:The OG + SC group showed the longest postoperative hospital stay (mean:12.3 days,median:11 days,interquartile range [IQR]:6-16 days),while OG + FT,LG + FT,and RG + FT groups recovered faster (mean:7.4,6.4,and 6.6 days,median:6,6,and 6 days,IQR:3-9,4-8,and 3-9 days,respectively,all P 〈 0.001).The postoperative rehabilitation parameters such as flatus time after surgery (4.7 ± 0.9,3.1 ± 0.8,3.0± 0.9,and 3.1 ± 0.9 days) followed the same manner.After 30 postoperative days&#39; follow-up,the total incidence of complications was 9.6% in OG + SC group,10.1% in OG + FT group,8.1% in LG + FT group,and 10.3% in RG + FT group.The complications showed no significant differences between the four groups (all P 〉 0.05).Conclusions:ERAS protocols alone could significantly bring fast recovery after surgery regardless of the surgical technique.MIS further reduces postoperative hospital stay.It is safe and effective to apply ERAS protocols combined with MIS for gastric cancer.

文摘Background: Most studies on enhanced recovery after surgery (ERAS) for gastric cancer exclude patients who received neoadjuvant chemotherapy. Here, we aimed to evaluate whether patients who received neoadjuvant chemotherapy can be enrolled into the ERAS program for locally advanced gastric cancer. Methods: From April 2015 to July 2017, 114 patients who received neoadjuvant chemotherapy for locally advanced gastric cancer were randomized into ERAS and standard care (SC) groups. Postoperative length of stay, complications, bowel function, and nutritional status were recorded. Results: The postoperative length of stay of the ERAS group was shorter compared with that of the SC group (5.9 ± 5.6 vs. 8.1 ± 5.3 days, P=0.037).The postoperative complication rate was 9.3% in the ERAS group and 11.5% in the SC group(P=0.700).The time to first flatus (2.7 ± 2.0 vs. 4.5 ± 4.6 days, P = 0.010) and time to a semi-liquid diet (3.2 ± 2.1 vs. 6.3 ± 4.9 days, P 〈 0.001) in the ERAS group were shorter compared with those in the SC group. On the 10thday after surgery, the values of weight, total protein, albumin, and prealbumin of the ERAS group were lower compared with those of the SC group. Conclusions: Patients who received neoadjuvant chemotherapy could be enrolled into ERAS programs for locally advanced gastric cancer. The nutritional status of these patients was not adversely affected.
文摘At present,natural orifice specimen extraction surgery(NOSES)has attracted more and more attention worldwide,because of its great advantages including minimal cutaneous trauma and post-operative pain,fast post-operative recovery,short hospital stay,and positive psychological impact.However,NOSES for the treatment of gastric cancer(GC)is still in its infancy,and there is great potential to improve its theoretical system and clinical practice.Especially,several key points including oncological outcomes,bacteriological concerns,indication selection,and standardized surgical procedures are raised with this innovative technique.Therefore,it is necessary to achieve an international consensus to regulate the implementation of GC-NOSES,which is of great significance for healthy and orderly development of NOSES worldwide.

文摘Effects of branches on the crystallization kinetics of polypropylene-g-polystyrene (PP-g-PS) and polypropylene-g- poly(n-butyl acrylate) (PP-g-PnBA) graft copolymers with well-defined molecular structures were systematically investigated by DSC. The Avrami equation was used to analyze the isothermal crystallization process, while the analysis of nonisothermal crystallization process was based on the Jeziorny-modified Avrami model and Mo model. The kinetics results of isothermal and nonisothermal crystallization verified the peculiar effects of branches on the crystallization process of PP backbones in PP-g-PS and PP-g-PnBA graft copolymers: on one hand, the interaction between branches (n-n interaction between PS branches, or dipole-dipole interaction between PnBA branches) restrained the mobility and reptation ability of the PP backbones, which hindered the crystallization process; on the other hand, the heterogeneous nucleation effect resulting from the branched structure and fluctuation-assisted nucleation mechanism (caused by microphase separation between the PS or PnBA rich phase and the PP rich phase) became more pronounced with increasing branch length, which facilitated the crystallization process.

文摘Background:Urinary catheterization(UC)is a conventional perioperative measure for major abdominal operation.Optimization of perioperative catheter management is an essential component of the enhanced recovery after surgery(ERAS)programme.We aimed to investigate the risk factors of urinary retention(UR)after open colonic resection within the ERAS protocol and to assess the feasibility of avoiding urinary drainage during the perioperative period.Methods:A total of 110 colonic-cancer patients undergoing open elective colonic resection between July 2014 and May 2018 were enrolled in this study.All patients were treated within our ERAS protocol during the perioperative period.Data on patients’demographics,clinicopathologic characteristics,and perioperative outcomes were collected and analysed retrospectively.Results:Sixty-eight patients(61.8%)underwent surgery without any perioperative UC.Thirty patients(27.3%)received indwelling UC during the surgical procedure.Twelve(10.9%)cases developed UR after surgery necessitating UC.Although patients with intraoperative UC had a lower incidence of post-operative UR[0%(0/30)vs 15%(12/80),P=0.034],intraoperative UC was not testified as an independent protective factor inmultivariate logistic analysis.The history of prostatic diseases and the body mass index were strongly associated with post-operative UR.Six patients were diagnosed with post-operative urinary-tract infection,among whom two had intraoperative UC and four were complicated with post-operative UR requiring UC.Conclusion:Avoidance of urinary drainage for open elective colonic resection is feasible with the implementation of the ERAS programme as the required precondition.Obesity and a history of prostatic diseases are significant predictors of postoperative UR.
