ABSTRACT
@#Objective To compare the safety of manual anastomosis and mechanical anastomosis after esophagectomy by meta-analysis. Methods The randomized controlled trials (RCTs) about manual anastomosis and mechanical anastomosis after esophagectomy were searched from PubMed, EMbase and The Cochrane Library from inception to January 2018 by computer, without language restrictions. Two authors according to the inclusion and exclusion criteria independently researched literature, extracted data, evaluated bias risk and used R software meta package for meta-analysis. Results Seventeen RCTs were enrolled, including 2 159 patients (1 230 by manual anastomosis and 1 289 by mechanical anastomosis). The results of meta-analysis showed that: (1) there was no significant difference in the incidence of anastomotic leakage between mechanical and manual anastomosis (RR=1.00, 95%CI 0.67–1.48, P=0.181); (2) no significant difference was found in the 30-day mortality (RR=0.95, 95%CI 0.61–1.49, P=0.631);(3) compared with manual anastomosis, the mechanical anastomosis group may increase the risk of anastomotic stenosis (RR=0.74, 95%CI 0.48-1.14, P<0.001). Conclusion Esophageal cancer surgery using a linear or circular stapler can increase the incidence of anastomotic stenosis after surgery. There is no significant difference in the anastomotic leakage and 30-day mortality between manual anastomosis, linear stapler and circular stapler.
ABSTRACT
Objective To study the influence of the operation through tubular stomach plus mechanical anastomosis on the life quality of patients with esophageal cancer.Methods Seventy patients with esophageal cancer were treated by operation,tubular stomach plus mechanical anastomosis were used.They were followed up for six months.The quality of life was evaluated.Results The average time for the operation was 120 min and the average amount of bleeding was 291.3ml.Compared with before surgery,there was significant difference in emotion,activity,sleep and diet ( P ＜ 0.05 ).Conclusion The operation through tubular stomach plus mechanical anastomosis could significantly improve the quality of life of patients with esophageal cancer.
ABSTRACT
Objective To review the outeonle of intrathoracic esophageal reconstruction using circular stapler after esophageal or cardiac cancer resection.Methods From June 1996 to April 2007,744 patients underwent tumor removal and intrathoracie esophageal reconstruction in Daping Hospital.Of all patients,658 suffered from thoracic esophageal cancer and the other 86 from cardiac cancer.The operative modalities consisted of gastroesophageal anastomosis at the top of tim thoracic cavity or above the aortic arch in 402 patients,gastroesophageal anastomosis below the aortic arch in 317,and total gastrectomy in 25(esophageal replacement with colon in 21 patients and esophagojejunostomy in 4).Results Anastomotie bleeding oecurred in 5 patients intraoperatively.One patient died of acute respiratory distress syndrome,1 of septic shock and 1 of hepatic failure postoperatively.Psychiatric disorder was observed in 5 patients,respiratory complications in 34,anastomotie fistula in 4,and anastomotic stricture in 20.Three weeks after the operation,the esophageal manometric examination in 25 patients showed that intraesophageal,anastomotie and intragastric pressures were(-0.2±2.0),(1 1.2±4.4)and(2.4±1.5)mm Hg(1 mm Hg=0.133 kPa),respectively.Twenty-four hour pH monitoring demonstrated that 13 patients had abnormal DeMeester score(＞14.72),3 of thenl developed reflux symptoms and got relieved after receiving acid suppression therapy for 1.0-2.2 months.The 13 patients with abnormal DeMeester score were followed up for 3-38 months,and the pH value of the esophagus was back to normal in 2 patients,and it almost remained the same in 9 patients.Two patients died of tumor reculTenee of metastasis.Conclusions Intratlmracic esophageal reconstruction with circular stapler is safe,reliable and able to reduce the postoperative complications such as anastomotic fistula.
