PS01.150: NEW METHOD OF ESOPHAGO-GASTRO ANASTOMOSIS AFTER ESOPHAGECTOMY

Abstract Background Medical science has introduced a lot of innovations and advanced equipment since the first esophagectomy was performed, nevertheless surgeons still continue to discuss benefits of certain methods and suggest changes to them because mortality and post-operative complications after esophagus resection remain high. The choice of the surgical approach, anastomosis location and its variety, conduit location and its variety, the volume of lymph node dissection and the use of minimally invasive present the most important and complex issues for surgeons. Methods The research included 40 patients who were given Lewis surgery for malignant tumors of esophagus in Shalimov's National Institute of Surgery and Transplantation: Control group comprised 20 patients who were given Lewis surgery involving end-to-side classical mechanical EGA through a circular suturing tool.; Research group comprised 20 patients who were given Lewis surgery involving invaginated mechanical EGA. (image 1). The objects for estimation included post-operative mortality as well as the number of post-operative anastomosis complications: the number of EGA leakages in the early post-operative period and the number of post operative strictures in the EGA area three months after the surgery. Data processing was done by means of Statistic—licensed application programs for Windows. Differences were considered valid if р < 0,05. Results Research group did not register a single case of EGA leakage while one patient in control group (р < 0,05). had the leakage which was stopped by means of ‘Endovac’ system. There were 2 cases of esophagus post-operative strictures which developed 3 months after the surgery in the research group which was less than in the control group which saw 6 cases of strictures of EGA (р < 0,05). Neither of the groups had any cases of post-operative mortality. Conclusion Our results allows us to conclude that invaginated mechanical EGA within Lewis surgery reduces post-operative complications of anastomosis in patients with esophagectomy.
