Clinical Effect Observation Of Delta-shaped Anastomosis In Single-utility Incision Video-assisted Thoracoscopic And Laparoscopic In The Treatment Of Esophageal Carcinoma

Objective: To investigate the technical feasibility,safety,and clinical efficacy of delta-shaped anastomosis in single-utility incision video-assisted thoracoscopic and laparoscopic in the treatment of esophageal carcinoma,and summarize the clinical experience.delta-shapedMethods: A randomized control study,according to the Yixing People's Hospital,100 cases of middle and low thoracic esophageal carcinoma were randomly divided into A group(single-utility incision VAST and end to side circular stapled anastomosis,n=30)?B group(four-port VAST and end to side circular stapled anastomosis,n=36)and C group(ingle-utility incision VAST and delta-shaped anastomosis,n=34).Operation time,intraoperative blood loss,the number of surgeries converted to open,chest drainage duration,degree of chest pain,lymph node dissection number,postoperative complications(pulmonary infection,recurrent laryngeal nerve injury,anastomotic fistula and stricture)were compared.Results: All patients of three groups patients reached R0 resection surgery,postoperative pathology confirmed the vertical cut end were negative.There were no statistically significant differences with operation time(248.67±27.00 vs 236.39±34.16min),intraoperative blood loss(166.33±46.19 vs 155.28±52.78ml),the number of surgeries converted to open(2/30 vs 1/36),chest drainage duration(6.77±2.69 vs7.28±3.22d),lymph node dissection number(17.27±3.08 vs 18.19±3.87),pulmonary infection(2/30 vs 4/36),recurrent laryngeal nerve injury(1/30 vs 0/36)between A and B group.There were statistical difference in degree of chest pain(3.43±1.14 vs 4.31±1.53 score)between A and B group.There were no statistically significant difference in anastomotic fistula(1/30 vs 3/34)between A and C group.There were statistical difference in anastomotic stricture(5/30 vs 0/34)between A and C group.Conclusion: Delta-shaped anastomosis in single-utility incision video-assisted thoracoscopic and laparoscopic in the treatment of esophageal carcinoma is technically safe and feasible,that can relieve pain and reduce the anastomotic strictures.
