Objective To explore an effective and minimal invasive drainage procedure for intrathoracic anastomotic leakage after esophagectomy. Method A total of 14 patients (10 males and 4 females, aged 48 to 70 years) with encapsulated effusion due to thoracic anastomotic leakage after esophagectomy were performed accurate thoracic drainage which was guided by ultrasonography in Renji Hospital from January 2012 through December 2014. The J shape flexible catheter was placed into the effusion cavity near the leakage. Gasric drainage and enteral nutrition support were conducted as well. Result All the patients with leakage healed smoothly. The hospital stay was 27 to 94 days. Time of drainage was 17 to 89 days. The drainage volume was 5-260 ml per day. No complication related to drainage occurred. Conclusion Placing the J shape flexible catheter for plural drainage guided by ultrasonography or chest CT scan is a desirable and less injured therapy for intrathoracic leakage after esophagectomy.
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.
ObjectiveTo analyze the risk factors of anastomotic leakage after esophagectomy.MethodsThe clinical data of 1 328 patients with esophageal cancer, who underwent esophagectomy in the First Affiliated Hospital of Henan University of Science and Technology from January 2010 to December 2016, were retrospectively analyzed. There were 726 males and 602 females, at an average age of 67.2±14.1 years. According to whether there was anastomotic leakage after operation, patients were divided into two groups: an anastomotic leakage group (167 patients) and a non-anastomotic leakage group (1 161 patients). Univariate and multivariate logistic regression analysis was used to identify related risk factors of anastomotic leakage after operation.Results The incidence of postoperative anastomotic leakage was 12.6% (167/1 328). Univariate analysis showed that body mass index, arrhythmia, chronic obstructive pulmonary disease (COPD), diabetes, preoperative albumin level, preoperative chemotherapy and chemoradiotherapy, lesion location, anastomosis types and postoperative pulmonary infection were associated with statistically significant increase in risk of cervical anastomotic leakage (P<0.05). Logistic regression analysis showed that preoperative COPD, lesion location and postoperative pulmonary infection were independent risk factors of cervical anastomotic leakage after esophagectomy (P<0.05).ConclusionThe occurrence of cervical anastomotic leakage after esophageal cancer is related to many factors. The preoperative COPD, the lesion location and the postoperative pulmonary infection are independent high risk factors. Paying attention to these factors and doing perioperative management can effectively reduce the occurrence of anastomotic leakage.
Objective To confirm the difference between internal and external pressure of cervical esophageal and to discuss the relations between cervical esophageal pressure difference with the formation of cervical anastomotic leakage. Methods In the present study, 12 New Zealand white rabbits were used. We applied a pressure transducer to describe the variation of pressure of intrathoracic, thoracic esophagus, cervical esophagus and upper esophageal sphincter during resting and cough. Pressure value was recorded and read through MD3000 system. And the difference between each point was analyzed. Results The pressures resulting from the cough induced were significantly higher in intrathoracic than in thoracical esophagous (10.2±0.6 cm H2O vs. 36.7±1.0 cm H2O), exhibited significantly higher in upper esophageal sphincter and thoracic esophagous than in cervical esophageal (7.5±0.2 cm H2O vs. 12.0±0.4 cm H2O, vs. 10.2±0.6 cm H2O). Conclusion Cervical anastomotic leaks are affected by many factors.And the most notabe one is the constant pressure from inside-out around cervical anastomotic.
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.
ObjectiveTo investigate the risk factors for anastomotic leakage after McKeown esophagectomy, and to establish a risk prediction model for early clinical intervention.MethodsWe selected 469 patients including 379 males and 90 females, with a median age of 67 (42-91) years, who underwent McKeown esophagectomy in our department from 2018 to 2019. The clinical data of the patients were analyzed.ResultsAmong the 469 patients, 7.0% (33/469) patients had anastomotic leakage after McKeown esophagectomy. Logistic analysis showed that the risk factors for anastomotic leakage were operation time >4.5 h, postoperative low albumin and postoperative hypoxemia (P<0.05). A prognostic nomogram model was established based on these factors with the area under the receiver operator characteristic curve of 0.769 (95%CI 0.677-0.861), indicating a good predictive value.ConclusionOperation time >4.5 h, postoperative low albumin and postoperative hypoxemia are the independent risk factors for anastomotic leakage after McKeown esophagectomy. Through the nomogram prediction model, early detection and intervention can be achieved, and the hospital stay can be shortened.
