Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
ObjectiveTo investigate the association between the preoperative nutritional risk and anastomotic leakage following anterior resection for the rectal cancer. MethodsA total of 321 patients with rectal cancer underwent anterior resection in our hospital between January 2008 and December 2013 were retrospectively analyzed. Preoperative nutritional status was evaluated using NRS 2002. Correlation of clinicopathologic characteristics with postoperative anastomotic leakage was evaluated using single factor analysis and Logistic regression model. ResultsAmong the 321 patients, the incidence of postoperative anastomotic leakage was 5.6% (18/321). Single factor analysis showed that the NRS2002 score≥3, clinicalpathologic stage (Ⅲ-Ⅳstage) and distance of tumor from the anal verge were the risk factors of anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Logistic regression analysis revealed that the NRS2002 score (OR=4.125, 95% CI=2.062-7.004), clinicalpathologic stage (OR=3.334, 95% CI=2.062-7.004) and the distance of tumor from the anal verge (OR=2.341, 95% CI=2.559-15.838) were the independent risk factors for anastomotic leakage after anterior leakage following anterior resection for rectal cancer. Conciusions Preoperative NRS2002 score is helpful to predict the risk of anastomotic leakage after anterior resection of rectal cancer. Nutrition education should be strengthened to decrease the morbidity of the anastomotic leakage following anterior resection for the patients who's NRS2002 score≥3.
ObjectiveTo compare the complication morbidity of mechanical and hand-sewn esophagogastric anastomosis systemically. MethodsMedline (January 1960 to June 2015), EMbase (January 1980 to June 2015), Cochrane Library (January 1996 to June 2015), Web of Science (January 1980 to June 2015) and other databases were searched to identify randomized controlled trials (RCTs) about comparing the complication morbidity of hand-sewn and mechanical anastomosis. Moreover, the references were searched by search engines such as Google Scholar. Papers were screened according to the inclusion and exclusion criteria. And then the data were extracted. The quality of current meta-analysis was assessed by GRADE profiler 3.6 software. The meta-analysis was conducted using Stata 12.0 software. ResultsA total of 1 611 patients in 14 RCTs were reviewed. The results suggested that the anastomatic leakage rate of mechanical method showed no significant difference from that of hand-sewn method[RR=1.07, 95%CI (0.76, 1.51), P=0.699]. While the anastomatic stenosis rate was even higher[RR=1.59, 95%CI (1.21, 2.09), P=0.001]. ConclusionMechanical method can't reduce the anastomotic leakage rate following esophagogastrostomy, while it maybe increase the risk of anastomotic stenosis on the contrary. The patients' physical condition should be considered when surgeons make the choice.
Objective To analyse postoperative complications and cause of death for carcinoma of esophagus. Methods A retrospective study was undertaken for data of 2 085 patients with esophageal carcinoma from 1963 to 2003, the patients were divided into group A (332 cases,1963-1983), group B(727 cases,1984-1993) and group C (1 026 cases,1994-2003) by time. The postoperative complications and cause of death were analysed. Results Resectability rate, incidence rate of postoperative complications and hospital mortality were 90.84%(1 894/2 085), 11.61% (242/2 085) and 1.82% (38/2 085) respectively. Main complications were pulmonary complications (3.93%,82/2 085),anastomotic leak (3.12%,59/1 894), and cardiovascular disease (1.29%,27/2 085). Resectability rate of group B and group C were higher than that of group A, incidence rate of postoperative complications and hospital mortality of group B and group C were lower than that of group A. Resectability rate of group C were higher than that of group B, incidence rate of postoperative complications except pulmonary complications and hospital mortality of group C were lower than those of group B. Conclusions Pulmonary complications and anastomotic leak are main postoperative complications and cause of hospital death for carcinoma of esophagus, they are decreasing in recent years because of the progress of anesthetic,surgical technique and perioperative management.
The risk factors of esophagogastric anastomotic leak in the perioperative period include malnutrition, smoking, steroid use, bowel preparation, chemotherapy, duration of surgery, vasopressor drugs use, intravenous fluid administration, blood transfusion and surgical anastomotic technique, which can be reduced with the improvement of surgeons' ability to identify the high-risk patients. This article summarizes the specific measures for these risk factors: preoperative nutritional support for 5–7 d for malnourished patients, full intestinal preparation, perioperative smoking cessation, limitation of steroids and vasopressors drug applications, avoidance of early operations (<4 weeks) following chemotherapy, and the goal-directed fluid management.
ObjectiveTo explore the superiority of pleural tenting in Ivor-Lewis esophagogastrectomy. MethodsWe prospectively included 200 esophagus cancer patients with Ivor-Lewis esophagogastrectomy in our hospital between 2013 and 2015 year. The patients were allocated into two groups including a trial group and a control group with 100 patients in each group. There were 72 males and 28 females at an average age of 54.76±6.62 years in the trial group and 66 males and 34 females at an average age of 55.72±6.38 years in the control group. In the trial group pleural tenting was used to cover the anastomotic stoma and gastric tube, while in the control group pleural tenting was not used. Postoperative complications after one year, pressure on the level of the anastomotic stoma, and the grade of quality of life were compared between the two groups. ResultNo statistically significant differences were found in preoperative epidemiological and postoperative pathological characteristics, as well as the postoperative complications and the one-year survival rate (P > 0.05). Quality of life was better in the trial group than that of the control group. ConclusionPleural tenting is a simple, safe, and effective technique for improving quality of life of the patients.
【Abstract】ObjectiveTo study the positive effect of recombinant human epidermal growth factor (rhEGF) on rabbit intestinal anastomotic wound healing after bowel resection. MethodsFortyeight white rabbits were randomly divided into study group in which rhEGF was injected and spinged in the submucosa and mucosa respectively during intestinal anastomosis after bowel resection, and control group in which only intestinal resection and anastomosis was performed. The leukocyte was counted. The incidence of anastomotic leakage and the synthesis of collagen fibrils and hydroxyproline were observed. ResultsThe leukocyte numbers in the anastomotic tissue in two groups rabbits increased slightly 3 d, 5 d and 7d after intestinal anastomosis, but the difference between study group and control group was insignificant (Pgt;0.05). The incidence of anastomotic leakage in the control group (16.7%) was higher than that of the study group (4.3%). The area of collagen fibrils 3 d, 5 d and 7d after intestinal anastomosis in the study group were significantly more than that in the control group (P＜0.05). Number of fibroblast was higher in the study group and the cells appeared bigger nucleus and dense colouration as well as enriched plasm. Angiogenesis in anastomosis tissue in the study group was significant and normal structure was present. Cell structure of anastomosis mucosa was damaged in the control group. Synthesis of hydroxyproline in anastomotic tissue 5 d and 7 d after anastomosis in the study group was more than that in the control group (P＜0.05).ConclusionInflammation was present in the whole process of wound healing, and local using of EGF had insignificant effect on system inflammation. EGF functions as chemoattractant and increases the recruitment of leukocytes, monocytes and fibroblasts into the wound area. EGF increases the production of collagen, angiogenesis and the synthesis of hydroxyproline. So EGF could promote wound healing and protect from anastomosis leakage in this study.
ObjectiveTo investigate the feasibility of thoracolapascopic esophagectomy (TLE) without routine nasogastric (NG) intubation for patients with esophageal cancer (EC). MethodsClinical data of 78 EC patients under-going TLE without perioperative NG intubation in Affiliated Cancer Hospital of Zhengzhou University from January to September 2013 were analyzed (non-NG intubation group, including 48 male and 30 female patients with their age of 61.1± 8.5 years). Seventy-eight EC patients undergoing TLE with routine NG intubation for 7 days in 2012 were chosen as the control group (NG intubation group, including 50 male and 28 female patients with their age of 60.3±7.0 years). Operation time, postoperative morbidity, gastrointestinal functional recovery and patient discomfort were compared between the 2 groups. ResultsThere was no in-hospital death in either groups. There was no statistic difference in the incidences of pulmonary infection (16.7% vs. 19.2%, P=0.676), anastomotic leakage (1.3% vs. 2.6%, P=0.560) or NG tube replacement (3.8% vs. 2.6%, P=0.649) between non-NG intubation group and NG intubation group. Time for recovery of intestinal motility (2.5± 1.1 days vs. 4.3±1.2 days, P < 0.05) and time for air evacuation (3.6±1.7 days vs. 5.8±2.1 days, P < 0.05) of non-NG intubation group were significantly shorter than those of NG intubation group. Ninety-seven percent of the patients (76/78)in NG intubation group had uncomfortable feeling including dry mouth and sore throat, and only 6% of the patients (5/78) in non-NG intubation group had nausea. All the patients were followed up for 3 months after discharge. There was no intestinal obstruction, pneumonia or late anastomotic leakage during follow-up. ConclusionTLE without routine NG intubation is safe and feasible for EC patients, which can not only reduce patients' discomfort but also improve early recovery of gastrointestinal function.
ObjectiveTo analyze the common reasons of anastomotic leakage following sphincter preservation for rectal cancer, and to explore the better prevention and treatment strategies. MethodThe related literatures of the definition, common causes, and prevention and treatment status of anastomotic leakage were reviewed. ResultsCurrently rectal cancer was one of common malignant tumors, including about 2/3 low rectal cancer.Recently, sphincter preserving surgery had become the preferred surgical procedure.However, the incidence of anastomotic leakage keeping in higher was still the most serious and common complications.Through improving the general condition of the patients, improving surgical techniques, and standardized treatment could effectively reduce the incidence of anastomotic leakage. ConclusionReasonable preoperative assessment for the basic situation of patients with rectal cancer, standardized and individualized treatments, contribute to reduce incidence of anastomotic leakage and improve clinical outcomes in patients with low rectal cancer.
ObjectiveTo systematically review risk factors for esophagogastric anastomotic leakage (EGAL) after esophageal cancer surgery for adults to provide theoretical basis for clinical prevention and treatment.MethodsPubMed, Web of Science, The Cochrane Library, WanFang Data, VIP, CNKI and CBM were searched from inception to January 2020 to collect case control studies and cohort studies about risk factors for EGAL after esophageal cancer surgery. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, and then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 33 studies were included, including 19 case-control studies and 14 cohort studies, all of which had a Newcastle-Ottawa Scale (NOS)≥6. There were 26 636 patients, including 20 283 males and 6 353 females, and there were 9 587 patients in China and 17 049 patients abroad. The results of meta-analysis showed that the following factors could increase the risk for EGAL (P≤0.05), including patient factors (18): age, sex, body mass index (BMI), smoking history, smoking index (≥400), alcohol history, digestive tract ulcer, respiratory disease, lower ratio of forced expiratory volume in one second to forced vital capacity (FEV1/FVC), chronic obstructive pulmonary disease (COPD), coronary atherosclerosis, peripheral vascular disease, arrhythmia, diabetes, hypertension, cerebrovascular disease, celiac trunk calcification and descending aortic calcification; preoperative factors (6): abnormal liver function, renal insufficiency, American Society of Anesthesiologists (ASA) grading, neoadjuvant radiotherapy and preoperative albumin<35 g/L, preoperative lower albumin; intraoperative factors (7): retrosternal route, cervical anastomosis, thoracoscopic surgery, operation time≥4.5 h, tubular stomach, upper segment tumor, splenectomy; postoperative factors (5): respiratory failure, postoperative arrhythmia, use of fiberoptic bronchoscopy, pulmonary infection, deep venous thrombosis. Neoadjuvant chemotherapy could reduce the risk for postoperative EGAL (P<0.05). However, age≥60 years, upper gastrointestinal inflammation, diffusing capacity for carbon monoxide (DLCO%), thoracic surgery history, abdominal surgery history, glucocorticoid drugs history, neoadjuvant chemoradiotherapy, anastomotic embedding, end-to-end anastomosis, hand anastomosis, intraoperative blood loss and other factors were not significantly correlated with EGAL.ConclusionCurrent evidence suggests that the risk factors for postoperative EGAL include age, sex, BMI, smoking index, alcohol history, peptic ulcer, FEV1/FVC, COPD, diabetes, ASA grading, neoadjuvant radiotherapy, preoperative albumin<35 g/L, cervical anastomosis, thoracoscopic surgery, operation time≥4.5 h, tubular stomach, upper segment tumor, intraoperative splenectomy, postoperative respiratory failure, postoperative arrhythmia and other risk factors. Neoadjuvant chemotherapy may be the protection factor for EGAL. Due to limited study quality, more high quality studies are needed to verify the conclusion.
